Hepatomegaly:
Medical causes
(Handbook of Signs & Symptoms (Third Edition))
Amyloidosis
Amyloidosis is a rare disorder that may cause hepatomegaly and mild jaundice as well as renal, cardiac, and other GI effects.
Cirrhosis
Late in cirrhosis, the liver becomes enlarged, nodular, and hard Other late signs and symptoms affect all body systems
Respiratory findings include limited thoracic expansion due to abdominal ascites, leading to hypoxia. Central nervous system findings include signs and symptoms of hepatic encephalopathy, such as lethargy, slurred speech, asterixis, peripheral neuritis, paranoia, hallucinations, extreme obtundation, and coma. Hematologic signs include epistaxis, easy bruising, and bleeding gums. Endocrine findings include testicular atrophy, gynecomastia, loss of chest and axillary hair, or menstrual irregularities. Integumentary effects include abnormal pigmentation, jaundice, severe pruritus, extreme dryness, poor tissue turgor, spider angiomas, and palmar erythema.
The patient may also develop fetor hepaticus, enlarged superficial abdominal veins, muscle atrophy, right upper quadrant pain that worsens when he sits up or leans forward, and a palpable spleen. Portal hypertension — elevated pressure in the portal vein — causes bleeding from esophageal varices.
Diabetes mellitus
Poorly controlled diabetes in overweight patients commonly produces fatty infiltration of the liver, hepatomegaly, and right upper quadrant tenderness along with polydipsia, polyphagia, and polyuria
These features are more common in type 2 than in type 1 diabetes A chronically enlarged fatty liver typically produces no symptoms except for slight tenderness.
Granulomatous disorders
Sarcoidosis, histoplasmosis, and other such disorders commonly produce a slightly enlarged, firm liver.
Hepatic abscess
Hepatomegaly may accompany a fever (a primary sign), nausea, vomiting, chills, weakness, diarrhea, anorexia, an elevated right hemidiaphragm, and right upper quadrant pain and tenderness.
Hepatitis
In viral hepatitis, early signs and symptoms include nausea, anorexia, vomiting, fatigue, malaise, photophobia, a sore throat, a cough, and a headache Hepatomegaly occurs in the icteric phase and continues during the recovery phase
Also, during the icteric phase, the early signs and symptoms diminish and others appear: liver tenderness, slight weight loss, dark urine, clay-colored stools, jaundice, pruritus, right upper quadrant pain, and splenomegaly.
Leukemia and lymphomas
Leukemia and lymphomas are proliferative blood cell disorders that typically cause moderate to massive hepatomegaly and splenomegaly as well as abdominal discomfort
General signs and symptoms include malaise, a low-grade fever, fatigue, weakness, tachycardia, weight loss, bleeding disorders, and anorexia.
Liver cancer
Primary tumors commonly cause irregular, nodular, firm hepatomegaly, with pain or tenderness in the right upper quadrant and a friction rub or bruit over the liver Common related findings are weight loss, anorexia, cachexia, nausea, and vomiting
Peripheral edema, ascites, jaundice, and a palpable right upper quadrant mass may also develop. When metastatic liver tumors cause hepatomegaly, the patient’s accompanying signs and symptoms reflect his primary cancer.
Mononucleosis (infectious)
Occasionally, infectious mononucleosis causes hepatomegalyProdromal symptoms include a headache, malaise, and fatigue. After 3 to 5 days, the patient typically develops a sore throat, cervical lymphadenopathy, and temperature fluctuations. He may also develop stomatitis, palatal petechiae, periorbital edema, splenomegaly, exudative tonsillitis, pharyngitis and, possibly, a maculopapular rash.
Obesity
Hepatomegaly can result from fatty infiltration of the liver
Weight loss reduces the liver’s size.
Pancreatic cancer
In pancreatic cancer, hepatomegaly accompanies such classic signs and symptoms as anorexia, weight loss, abdominal or back pain, and jaundice Other findings include nausea, vomiting, a fever, fatigue, weakness, pruritus, and skin lesions (usually on the legs).
Pericarditis
In chronic constrictive pericarditis, an increase in systemic venous pressure produces marked congestive hepatomegaly Distended jugular veins (more prominent on inspiration) are a common findingThe usual signs of cardiac disease typically are absent; other features include peripheral edema, ascites, fatigue, and decreased muscle mass.
Jaundice:
Medical causes
(Handbook of Signs & Symptoms (Third Edition))
Carcinoma
Cancer of the ampulla of Vater initially produces fluctuating jaundice, mild abdominal pain, a recurrent fever, and chills
Occult bleeding may be its first sign. Other findings include weight loss, pruritus, and back pain.
Hepatic cancer (primary liver cancer or another cancer that has metastasized to the liver) may cause jaundice by causing obstruction of the bile duct. Even advanced cancer causes nonspecific signs and symptoms, such as right upper quadrant discomfort and tenderness, nausea, weight loss, and a slight fever. Examination may reveal irregular, nodular, firm hepatomegaly; ascites; peripheral edema; a bruit heard over the liver; and a right upper quadrant mass.
Withpancreatic cancer,progressive jaundice — possibly with pruritus — may be the only sign. Related early findings are nonspecific, such as weight loss and back or abdominal pain. Other signs and symptoms include anorexia, nausea and vomiting, a fever, steatorrhea, fatigue, weakness, diarrhea, pruritus, and skin lesions (usually on the legs).
Cholangitis
Obstruction and infection in the common bile duct cause Charcot’s triad: jaundice, right upper quadrant pain, and a high fever with chills.
Cholecystitis
Cholecystitis produces nonobstructive jaundice in about 25% of patients
Biliary colic typically peaks abruptly, persisting for 2 to 4 hours. The pain then localizes to the right upper quadrant and becomes constant. Local inflammation or passage of stones to the common bile duct causes jaundice. Other findings include nausea, vomiting (usually indicating the presence of a stone), a fever, profuse diaphoresis, chills, tenderness on palpation, a positive Murphy’s sign and, possibly, abdominal distention and rigidity.
Cholelithiasis
Cholelithiasis commonly causes jaundice and biliary colic
It’s characterized by severe, steady pain in the right upper quadrant or epigastrium that radiates to the right scapula or shoulder and intensifies over several hours. Accompanying signs and symptoms include nausea and vomiting, tachycardia, and restlessness. Occlusion of the common bile duct causes a fever, chills, jaundice, clay-colored stools, and abdominal tenderness. After consuming a fatty meal, the patient may experience vague epigastric fullness and dyspepsia.
Cirrhosis
With Laënnec’s cirrhosis, mild to moderate jaundice with pruritus usually signals hepatocellular necrosis or progressive hepatic insufficiency
Common early findings include ascites, weakness, leg edema, nausea and vomiting, diarrhea or constipation, anorexia, weight loss, and right upper quadrant pain. Massive hematemesis and other bleeding tendencies may also occur. Other findings include an enlarged liver and parotid gland, clubbed fingers, Dupuytren’s contracture, mental changes, asterixis, fetor hepaticus, spider angiomas, and palmar erythema. Males may exhibit gynecomastia, scanty chest and axillary hair, and testicular atrophy; females may experience menstrual irregularities.
With primary biliary cirrhosis,fluctuating jaundice may appear years after the onset of other signs and symptoms, such as pruritus that worsens at bedtime (commonly the first sign), weakness, fatigue, weight loss, and vague abdominal pain. Itching may lead to skin excoriation. Associated findings include hyperpigmentation; indications of malabsorption, such as nocturnal diarrhea, steatorrhea, purpura, and osteomalacia; hematemesis from esophageal varices; ascites; edema; xanthelasmas; xanthomas on the palms, soles, and elbows; and hepatomegaly.
Dubin-Johnson syndrome
With Dubin-Johnson syndrome, which is a rare, chronic inherited syndrome, fluctuating jaundice that increases with stress is the major sign, appearing as late as age 40
Related findings include slight hepatic enlargement and tenderness, upper abdominal pain, nausea, and vomiting.
Heart failure
Jaundice due to liver dysfunction occurs in patients with severe right-sided heart failure
Other effects include jugular vein distention, cyanosis, dependent edema of the legs and sacrum, steady weight gain, confusion, hepatomegaly, nausea and vomiting, abdominal discomfort, and anorexia due to visceral edema. Ascites are a late sign. Oliguria, marked weakness, and anxiety may also occur. If left-sided heart failure develops first, other findings may include fatigue, dyspnea, orthopnea, paroxysmal nocturnal dyspnea, tachypnea, arrhythmias, and tachycardia.
Hepatic abscess
Multiple abscesses may cause jaundice, but the primary effects are a persistent fever with chills and sweating
Other findings include steady, severe pain in the right upper quadrant or midepigastrium that may be referred to the shoulder; nausea and vomiting; anorexia; hepatomegaly; an elevated right hemidiaphragm; and ascites.
Hepatitis
Dark urine and clay-colored stools usually develop before jaundice in the late stages of acute viral hepatitis
Early systemic signs and symptoms vary and include fatigue, nausea, vomiting, malaise, arthralgia, myalgia, a headache, anorexia, photophobia, pharyngitis, a cough, diarrhea or constipation, and a low-grade fever associated with liver and lymph node enlargement. During the icteric phase (which subsides within 2 to 3 weeks unless complications occur), systemic signs subside, but an enlarged, palpable liver may be present along with weight loss, anorexia, and right upper quadrant pain and tenderness.
Pancreatitis (acute)
Edema of the head of the pancreas and obstruction of the common bile duct can cause jaundice; however, the primary symptom of acute pancreatitis is usually severe epigastric pain that commonly radiates to the back
Lying with the knees flexed on the chest or sitting up and leaning forward brings relief. Early associated signs and symptoms include nausea, persistent vomiting, abdominal distention, and Turner’s or Cullen’s sign. Other findings include a fever, tachycardia, abdominal rigidity and tenderness, hypoactive bowel sounds, and crackles.
Severe pancreatitis produces extreme restlessness; mottled skin; cold, diaphoretic extremities; paresthesia; and tetany — the last two being symptoms of hypocalcemia. Fulminant pancreatitis causes massive hemorrhage.
Sickle cell anemia
Hemolysis produces jaundice in the patient with sickle cell anemia
Other findings include impaired growth and development, increased susceptibility to infection, life-threatening thrombotic complications and, commonly, leg ulcers, swollen (painful) joints, a fever, and chills. Bone aches and chest pain may also occur. Severe hemolysis may cause hematuria and pallor, chronic fatigue, weakness, dyspnea (or dyspnea on exertion), and tachycardia. The patient may also have splenomegaly. During a sickle cell crisis, the patient may have severe bone, abdominal, thoracic, and muscular pain; a low-grade fever; and increased weakness, jaundice, and dyspnea.
Other causes
Drugs
Many drugs may cause hepatic injury and resultant jaundice
Examples include acetaminophen, phenylbutazone, I.V. tetracycline, isoniazid, hormonal contraceptives, sulfonamides, mercaptopurine, erythromycin estolate, niacin, troleandomycin, androgenic steroids, 3-hydroxy-3-methylglutaryl reductase inhibitors, phenothiazines, ethanol, methyldopa, rifampin, and dilantin.
Treatments
Upper abdominal surgery may cause postoperative jaundice, which occurs secondary to hepatocellular damage from the manipulation of organs, leading to edema and obstructed bile flow; from the administration of halothane; or from prolonged surgery resulting in shock, blood loss, or blood transfusion.
A surgical shunt used to reduce portal hypertension (such as a portacaval shunt) may also produce jaundice.
Introduction: Malignant Neoplasms:
What causes cancer?
(Professional Guide to Diseases (Eighth Edition))
Researchers have found that cancer develops from mutations within the genes of cells. Thus, cancer is a genetic disease. Cancer susceptibility genes are of two types. Some are oncogenes, which activate cell division and influence embryonic development, and some are tumor suppressor genes, which halt cell division.
These genes are typically found in normal human cells, but certain kinds of mutations may transform the normal cells. Inherited defects may cause a genetic mutation, whereas exposure to a carcinogen may cause an acquired mutation. Current evidence indicates that carcinogenesis results from a complex interaction of carcinogens and accumulated mutations in several genes.
In animal studies of the ability of viruses to transform cells, some human viruses exhibit carcinogenic potential. For example, the Epstein-Barr virus, the cause of infectious mononucleosis, has been linked to Burkitt's lymphoma and nasopharyngeal cancer.
High-frequency radiation, such as ultraviolet and ionizing radiation, damages the genetic material known as deoxyribonucleic acid (DNA), possibly inducing genetically transferable abnormalities. Other factors, such as a person's tissue type and hormonal status, interact to potentiate radiation's carcinogenic effect. Examples of substances that may damage DNA and induce carcinogenesis include:
❑alkylating agents — leukemia
❑aromatic hydrocarbons and benzopyrene (from polluted air) — lung cancer
❑asbestos — mesothelioma of the lung
❑tobacco — cancer of the lung, oral cavity and upper airways, esophagus, pancreas, kidneys, and bladder
❑vinyl chloride — angiosarcoma of the liver.
Diet has also been implicated, especially in the development of GI cancer as a result of a high animal fat diet. Additives composed of nitrates and certain methods of food preparation — particularly charbroiling — are also recognized factors.
The role of hormones in carcinogenesis is still controversial, but it seems that excessive use of some hormones, especially estrogen, produces cancer in animals. Also, the synthetic estrogen diethylstilbestrol causes vaginal cancer in some daughters of women who were treated with it. It's unclear, however, whether changes in human hormonal balance retard or stimulate cancer development.
Some forms of cancer and precancerous lesions result from genetic predisposition either directly (as in Wilms' tumor and retinoblastoma) or indirectly (in association with inherited conditions such as Down syndrome or immunodeficiency diseases). Expressed as autosomal recessive, X-linked, or autosomal dominant disorders, their common characteristics include:
❑early onset of malignant disease
❑increased incidence of bilateral cancer in paired organs (breasts, adrenal glands, kidneys, and eighth cranial nerve [acoustic neuroma])
❑increased incidence of multiple primary malignancies in nonpaired organs
❑abnormal chromosome complement in tumor cells.
Colorectal cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The exact cause of colorectal cancer is unknown, but studies showing concentration in areas of higher economic development suggest a relationship to diet (excess saturated animal fat). Other factors that magnify the risk of developing colorectal cancer include:
❑other diseases of the digestive tract
❑age (older than age 40)
❑history of ulcerative colitis (average interval before onset of cancer is 11 to 17 years)
❑familial polyposis (cancer almost always develops by age 50).
There are more than 130,000 cases of colorectal cancer diagnosed in the United States each year. It's the second-leading cause of cancer-related death, accounting for more than 50,000 per year. However, in almost all cases, it's treatable if caught early by colonoscopy.
Liver cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The immediate cause of liver cancer is unknown, but it may be a congenital disease in children. Adult liver cancer may result from environmental exposure to carcinogens, such as the chemical compound aflatoxin (a mold that grows on rice and peanuts), thorium dioxide (a contrast medium formerly used in liver radiography), Senecio alkaloids, and possibly androgens and oral estrogens.
Roughly 30% to 70% of patients with hepatomas also have cirrhosis. (Hepatomas are 40 times more likely to develop in a cirrhotic liver than in a normal one.)
Whether cirrhosis is a premalignant state or alcohol and malnutrition predispose the liver to develop hepatomas is still unclear. Other risk factors are exposure to the hepatitis C virus and the hepatitis B virus.
Liver cancer accounts for roughly 1% of all cancers in the United States and for 10% to 50% in Africa and parts of Asia. Liver cancer is most prevalent in men (particularly men older than age 60), and incidence increases with age. It's rapidly fatal, usually within 6 months, from GI hemorrhage, progressive cachexia, hepatic failure, or metastasis.
Malignant spinal neoplasms:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Primary tumors of the spinal cord may be extramedullary (occurring outside the spinal cord) or intramedullary (occurring within the cord itself). Extramedullary tumors may be intradural (meningiomas and schwannomas), which account for 60% of all primary malignant spinal cord neoplasms, or extradural (metastatic tumors from breasts, lungs, prostate, leukemia, or lymphomas), which account for 25% of these malignant neoplasms.
Intramedullary tumors, or gliomas (astrocytomas or ependymomas), are comparatively rare, accounting for only about 10%. In children, they're low-grade astrocytomas.
Spinal cord tumors are rare compared with intracranial tumors (ratio of 1:4). They occur equally in men and women, with the exception of meningiomas, which occur mostly in women. Spinal cord tumors can occur anywhere along the length of the cord or its roots.
Hepatomegaly:
Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))
Amyloidosis
This rare disorder can cause hepatomegaly and mild jaundice as well as renal, cardiac, and other GI effects.

The patient may also develop fetor hepaticus, enlarged superficial abdominal veins, muscle atrophy, right-upper-quadrant pain that worsens when he sits up or leans forward, and a palpable spleen. Portal hypertension—elevated pressure in the portal vein—causes bleeding from esophageal varices.
Diabetes mellitus
Poorly controlled diabetes in overweight patients commonly produces fatty infiltration of the liver, hepatomegaly, and right-upper-quadrant tenderness along with polydipsia, polyphagia, and polyuria. These features are more common in type 2 than in type 1 diabetes. A chronically enlarged fatty liver typically produces no symptoms except for slight tenderness.
Granulomatous disorders
Sarcoidosis, histoplasmosis, and other granulomatous disorders commonly produce a slightly enlarged, firm liver.
Heart failure
This disorder produces hepatomegaly along with jugular vein distention, cyanosis, nocturia, dependent edema of the legs and sacrum, steady weight gain, confusion and, possibly, nausea, vomiting, abdominal discomfort, and anorexia due to visceral edema. Ascites is a late sign. Massive right-sided heart failure may cause anasarca, oliguria, severe weakness, and anxiety. If left-sided heart failure precedes right-sided heart failure, the patient exhibits dyspnea, paroxysmal nocturnal dyspnea, orthopnea, tachypnea, arrhythmias, tachycardia, and fatigue.
Hemochromatosis
This rare disease of iron metabolism causes hepatomegaly, altered skin pigmentation and, possibly, cardiac failure.
Hepatic abscess
Hepatomegaly may accompany fever (a primary sign), nausea, vomiting, chills, weakness, diarrhea, anorexia, elevated right hemidiaphragm, and right-upper-quadrant pain and tenderness.
Hepatitis
In viral hepatitis, early signs and symptoms include nausea, anorexia, vomiting, fatigue, malaise, photophobia, sore throat, cough, and headache. Hepatomegaly occurs in the icteric phase and continues during the recovery phase. Also, during the icteric phase, the early signs and symptoms diminish and others appear: liver tenderness, slight weight loss, dark urine, clay-colored stools, jaundice, pruritus, right-upper-quadrant pain, and splenomegaly.
Leukemia and lymphomas
These proliferative blood cell disorders commonly cause moderate to massive hepatomegaly and splenomegaly as well as abdominal discomfort. General signs and symptoms include malaise, low-grade fever, fatigue, weakness, tachycardia, anorexia, weight loss, and bleeding disorders.
Liver cancer
Primary tumors commonly cause an enlarged, irregular, nodular, firm liver with pain or tenderness in the right upper quadrant and a friction rub or bruit over the liver. Common related findings are anorexia, weight loss, cachexia, nausea, and vomiting. Peripheral edema, ascites, jaundice, and a palpable right-upper-quadrant mass may also develop. When metastatic liver tumors cause hepatomegaly, the patient’s signs and symptoms reflect his primary cancer.
Mononucleosis (infectious)
Occasionally, this disorder causes hepatomegaly. Prodromal symptoms include headache, malaise, and fatigue. After 3 to 5 days, the patient typically develops a sore throat, cervical lymphadenopathy, and temperature fluctuations. He may also develop stomatitis, palatal petechiae, periorbital edema, splenomegaly, exudative tonsillitis, pharyngitis and, possibly, a maculopapular rash.
Obesity
Hepatomegaly can result from fatty infiltration of the liver. Weight loss reduces the liver’s size.
Pancreatic cancer
In this disease, hepatomegaly accompanies such classic signs and symptoms as anorexia, weight loss, abdominal or back pain, and jaundice. Other findings include nausea, vomiting, fever, fatigue, weakness, pruritus, and skin lesions (usually on the legs).
Pericarditis
In chronic constrictive pericarditis, an increase in systemic venous pressure produces marked congestive hepatomegaly. Distended jugular veins (more prominent on inspiration) are a common finding. The usual signs of heart disease typically are absent; other features include peripheral edema, ascites, fatigue, and decreased muscle mass.
Other causes
Drugs
Hepatomegaly is a rare but serious side effect of drugs used to treat HIV-positive hepatitis, such as tenofovir and lamivudine.
Jaundice [Icterus]:
Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))
Agnogenic myeloid metaplasia
This myeloproliferative disorder of the bone marrow may cause jaundice. Its typical effects, however, are associated with anemia, including fatigue, weakness, anorexia, massive splenomegaly, hepatomegaly, purpura, and bleeding tendencies.
Carcinoma
Cancer of the ampulla of Vater initially produces fluctuating jaundice, mild abdominal pain, recurrent fever, and chills. Occult bleeding may be its first sign. Other findings include weight loss, pruritus, and back pain.
Hepatic cancer (primary liver cancer or another cancer that has metastasized to the liver) may cause jaundice by causing obstruction of the bile duct. Even advanced cancer causes nonspecific signs and symptoms, such as right-upper-quadrant discomfort and tenderness, nausea, weight loss, and slight fever. Examination may reveal irregular, nodular, firm hepatomegaly, ascites, peripheral edema, a bruit heard over the liver, and a right-upper-quadrant mass.
With pancreatic cancer, progressive jaundice—possibly with pruritus—may be the only sign. Related early findings are nonspecific, such as weight loss and back or abdominal pain. Other signs and symptoms include anorexia, nausea and vomiting, fever, steatorrhea, fatigue, weakness, diarrhea, pruritus, and skin lesions (usually on the legs).
Cholangitis
Obstruction and infection in the common bile duct cause Charcot’s triad: jaundice, right-upper-quadrant pain, and high fever with chills.
Cholecystitis
This disorder produces nonobstructive jaundice in about 25% of patients. Biliary colic typically peaks abruptly, persisting for 2 to 4 hours. The pain then localizes to the right upper quadrant and becomes constant. Local inflammation or passage of stones to the common bile duct causes jaundice. Other findings include nausea, vomiting (usually indicating the presence of a stone), fever, profuse diaphoresis, chills, tenderness on palpation, a positive Murphy’s sign, and, possibly, abdominal distention and rigidity.
Cholelithiasis
This disorder commonly causes jaundice and biliary colic. It’s characterized by severe, steady pain in the right upper quadrant or epigastrium that radiates to the right scapula or shoulder and intensifies over several hours. Accompanying signs and symptoms include nausea and vomiting, tachycardia, and restlessness. Occlusion of the common bile duct causes fever, chills, jaundice, clay-colored stools, and abdominal tenderness. After consuming a fatty meal, the patient may experience vague epigastric fullness and dyspepsia.
Cholestasis
With benign, recurrent intrahepatic cholestasis, the patient experiences prolonged attacks of jaundice (sometimes spaced several years apart) accompanied by pruritus. Other signs and symptoms are similar to those of hepatitis—fatigue, nausea, weight loss, anorexia, pale stools, and right-upper-quadrant pain.
Cirrhosis
With Laënnec’s cirrhosis, mild to moderate jaundice with pruritus usually signals hepatocellular necrosis or progressive hepatic insufficiency. Common early findings include ascites, weakness, leg edema, nausea and vomiting, diarrhea or constipation, anorexia, weight loss, and right-upper-quadrant pain. Massive hematemesis and other bleeding tendencies may also occur. Other findings include an enlarged liver and parotid gland, clubbed fingers, Dupuytren’s contracture, mental changes, asterixis, fetor hepaticus, spider angiomas, and palmar erythema. Males may exhibit gynecomastia, scanty chest and axillary hair, and testicular atrophy; females may experience menstrual irregularities.
With primary biliary cirrhosis, fluctuating jaundice may appear years after the onset of other signs and symptoms, such as pruritus that worsens at bedtime (commonly the first sign), weakness, fatigue, weight loss, and vague abdominal pain. Itching may lead to skin excoriation. Associated findings include hyperpigmentation; indications of malabsorption, such as nocturnal diarrhea, steatorrhea, purpura, and osteomalacia; hematemesis from esophageal varices; ascites; edema; xanthelasmas; xanthomas on the palms, soles, and elbows; and hepatomegaly.
Dubin-Johnson syndrome
With this rare, chronic inherited syndrome, fluctuating jaundice that increases with stress is the major sign, appearing as late as age 40. Related findings include slight hepatic enlargement and tenderness, upper abdominal pain, nausea, and vomiting.
Glucose-6-phosphate dehydrogenase deficiency
Acute intravascular hemolysis following ingestion of such drugs as quinine or aspirin causes jaundice, pallor, dyspnea, tachycardia, and malaise. Palpation may reveal splenomegaly and hepatomegaly.
Heart failure
Jaundice due to liver dysfunction occurs in patients with severe right-sided heart failure. Other effects include jugular vein distention, cyanosis, dependent edema of the legs and sacrum, steady weight gain, confusion, hepatomegaly, nausea and vomiting, abdominal discomfort, and anorexia due to visceral edema. Ascites is a late sign. Oliguria, marked weakness, and anxiety may also occur. If left-sided heart failure develops first, other findings may include fatigue, dyspnea, orthopnea, paroxysmal nocturnal dyspnea, tachypnea, arrhythmias, and tachycardia.
Hemolytic anemia (acquired)
This disorder may produce prominent jaundice along with dyspnea, fatigue, pallor, tachycardia, and palpitations. Rapid hemolysis causes chills, fever, irritability, headache, and abdominal pain; severe hemolysis causes signs of shock.
Hepatic abscess
Multiple abscesses may cause jaundice, but the primary effects are persistent fever with chills and sweating. Other findings include steady, severe pain in the right upper quadrant or midepigastrium that may be referred to the shoulder; nausea and vomiting; anorexia; hepatomegaly; elevated right hemidiaphragm; and ascites.
Hepatitis
Dark urine and clay-colored stools usually develop before jaundice in the late stages of acute viral hepatitis. Early systemic signs and symptoms vary and include fatigue, nausea, vomiting, malaise, arthralgias, myalgias, headache, anorexia, photophobia, pharyngitis, cough, diarrhea or constipation, and a low-grade fever associated with liver and lymph node enlargement. During the icteric phase (which subsides within 2 to 3 weeks unless complications occur), systemic signs subside, but an enlarged, palpable liver may be present along with weight loss, anorexia, and right-upper-quadrant pain and tenderness.
Leptospirosis
Severe leptospirosis (Weil’s disease) may cause jaundice. This disorder begins suddenly with a frontal headache, severe muscle aches in the thighs and lumbar area, cutaneous hyperesthesia, abdominal pain, nausea, conjunctival suffusion, and vomiting. Chills and a rapidly rising fever follow. Signs and symptoms of meningeal irritation include drowsiness, decreased mentation, stiff neck, and positive Kernig’s and Brudzinski’s signs. Right-upper-quadrant tenderness, hepatomegaly, and jaundice indicate hepatic involvement; proteinuria, pyuria, and hematuria indicate renal involvement. Epistaxis, hematemesis, melena, and hemoptysis may also occur.
Pancreatitis (acute)
Edema of the head of the pancreas and obstruction of the common bile duct can cause jaundice; however, this disorder’s primary symptom is usually severe epigastric pain that commonly radiates to the back. Lying with the knees flexed on the chest or sitting up and leaning forward brings relief. Early associated signs and symptoms include nausea, persistent vomiting, abdominal distention, and Turner’s or Cullen’s sign. Other findings include fever, tachycardia, abdominal rigidity and tenderness, hypoactive bowel sounds, and crackles.
Severe pancreatitis produces extreme restlessness; mottled skin; cold, diaphoretic extremities; paresthesia; and tetany—the last two being symptoms of hypocalcemia. Fulminant pancreatitis causes massive hemorrhage.
Sickle cell anemia
Hemolysis produces jaundice in patients with this disorder. Other findings include impaired growth and development, increased susceptibility to infection, life-threatening thrombotic complications and, commonly, leg ulcers, (painful) swollen joints, fever, and chills. Bone aches and chest pain may also occur. Severe hemolysis may cause hematuria and pallor, chronic fatigue, weakness, dyspnea (or dyspnea on exertion), and tachycardia. The patient may also have splenomegaly. During a sickle cell crisis, the patient may have severe bone, abdominal, thoracic, and muscular pain; low-grade fever; and increased weakness, jaundice, and dyspnea.
Zieve syndrome
Caused by alcohol abuse, this relatively rare disorder produces abdominal pain and a sudden onset of severe jaundice. However, spider angiomas, ascites, and other signs of advanced liver disease are absent.
Other causes
Drugs
Many drugs may cause hepatic injury and resultant jaundice. Examples include acetaminophen, I.V. tetracycline, isoniazid, hormonal contraceptives, sulfonamides, mercaptopurine, erythromycin estolate, niacin, troleandomycin, androgenic steroids, HMG-CoA reductase inhibitors, phenothiazines, ethanol, methyldopa, rifampin, and phenytoin.
Treatments
Upper abdominal surgery may cause postoperative jaundice, which occurs secondary to hepatocellular damage from the manipulation of organs, leading to edema and obstructed bile flow; from the administration of halothane; or from prolonged surgery resulting in shock, blood loss, or blood transfusion.
A surgical shunt used to reduce portal hypertension (such as a portacaval shunt) may also produce jaundice.

Colorectal cancer:
Causes
(Handbook of Diseases)
The exact cause of colorectal cancer is unknown, but studies showing concentration in areas of higher economic development suggest a relation to diet (excess animal fat, particularly beef, and low fiber). Other factors that increase the risk of developing colorectal cancer include:
❑ other diseases of the digestive tract
❑ age (older than 40)
❑ history of ulcerative colitis (the average interval before onset of cancer is 11 to 17 years)
❑ familial polyposis (cancer almost always develops by age 50).
Liver cancer:
Causes
(Handbook of Diseases)
The immediate cause of liver cancer is unknown, but it may be a congenital disease in children. Adult liver cancer may result from environmental exposure to carcinogens, such as the chemical compound aflatoxin (a mold that grows on rice and peanuts), thorium dioxide (a contrast medium formerly used in liver radiography), Senecio alkaloids, androgens, or oral estrogens.
Risk factors
Roughly 30% to 70% of patients with hepatomas also have cirrhosis. (Hepatomas are 40 times more likely to develop in a cirrhotic liver than in a normal one.) Whether cirrhosis is a premalignant state or alcohol and malnutrition predispose the liver to develop hepatomas is still unclear. Another risk factor is exposure to the hepatitis B virus, although this risk will probably decrease with the availability of the hepatitis B vaccine.
Hepatomegaly:
Medical causes
(Signs & Symptoms: A 2-in-1 Reference for Nurses)
Cirrhosis
In late cirrhosis, the liver becomes enlarged, nodular, and hard. Other late signs and symptoms affect all body systems. Respiratory findings include limited thoracic expansion due to abdominal ascites, leading to hypoxia. Central nervous system findings include signs and symptoms of hepatic encephalopathy, such as lethargy, slurred speech, asterixis, peripheral neuritis, paranoia, hallucinations, extreme obtundation, and coma. Hematologic signs include epistaxis, easy bruising, and bleeding gums. Endocrine findings include testicular atrophy, gynecomastia, loss of chest and axillary hair, or menstrual irregularities. Integumentary effects include abnormal pigmentation, jaundice, severe pruritus, extreme dryness, poor tissue turgor, spider angiomas, and palmar erythema.
The patient may also develop fetor hepaticus, enlarged superficial abdominal veins, muscle atrophy, right-upper-quadrant pain that worsens when he sits up or leans forward, and a palpable spleen. Portal hypertension — elevated pressure in the portal vein — causes bleeding from esophageal varices.
Diabetes mellitus
Poorly controlled diabetes in overweight patients can produce fatty infiltration of the liver, hepatomegaly, and right-upper-quadrant tenderness along with polydipsia, polyphagia, and polyuria. These features are more common in type 2 than in type 1 diabetes. A chronically enlarged fatty liver typically produces no symptoms except for slight tenderness.
Heart failure
Heart failure produces hepatomegaly along with jugular vein distention, cyanosis, nocturia, dependent edema of the legs and sacrum, steady weight gain, confusion and, possibly, nausea, vomiting, abdominal discomfort, and anorexia due to visceral edema. Ascites is a late sign. Massive right-sided heart failure may cause anasarca, oliguria, severe weakness, and anxiety. If left-sided heart failure precedes right-sided heart failure, the patient exhibits dyspnea, orthopnea, paroxysmal nocturnal dyspnea, tachypnea, arrhythmias, tachycardia, and fatigue.
Hepatitis
In viral hepatitis, early signs and symptoms include nausea, anorexia, vomiting, fatigue, malaise, photophobia, sore throat, cough, and headache. Hepatomegaly occurs in the icteric phase and continues during the recovery phase. Also, during the icteric phase, the early signs and symptoms diminish and others appear: liver tenderness, slight weight loss, dark urine, clay-colored stools, jaundice, pruritus, right-upper-quadrant pain, and splenomegaly.
Leukemia and lymphomas
Leukemia and lymphomas are proliferative blood cell disorders that commonly cause moderate to massive hepatomegaly and splenomegaly as well as abdominal discomfort. General signs and symptoms include malaise, low-grade fever, fatigue, weakness, tachycardia, weight loss, bleeding disorders, and anorexia.
Liver cancer
Primary tumors commonly cause irregular, nodular, firm hepatomegaly, with pain or tenderness in the right upper quadrant and a friction rub or bruit over the liver. Common related findings are weight loss, anorexia, cachexia, nausea, and vomiting. Peripheral edema, ascites, jaundice, and a palpable right-upper-quadrant mass may also develop. When metastatic liver tumors cause hepatomegaly, the patient’s accompanying signs and symptoms reflect his primary cancer.
Mononucleosis (infectious)
Occasionally, infectious mononucleosis causes hepatomegaly. Prodromal symptoms include headache, malaise, and fatigue. After 3 to 5 days, the patient typically develops sore throat, cervical lymphadenopathy, and temperature fluctuations. He may also develop stomatitis, palatal petechiae, periorbital edema, splenomegaly, exudative tonsillitis, pharyngitis and, possibly, a maculopapular rash.
Obesity
Hepatomegaly can result from fatty infiltration of the liver. Weight loss reduces the liver’s size. Obesity may also produce findings related to respiratory difficulties, hypertension, cardiovascular disease, diabetes, renal disease, gallbladder disease, and psychological difficulties.
Pancreatic cancer
In pancreatic cancer, hepatomegaly accompanies such classic signs and symptoms as anorexia, weight loss, abdominal or back pain, and jaundice. Other findings include nausea, vomiting, fever, fatigue, weakness, pruritus, and skin lesions (usually on the legs).
Jaundice:
Medical causes
(Signs & Symptoms: A 2-in-1 Reference for Nurses)
Carcinoma
Cancer of the ampulla of Vater initially produces fluctuating jaundice, mild abdominal pain, recurrent fever, and chills. Occult bleeding may be its first sign. Other findings include weight loss, pruritus, and back pain.
Hepatic cancer (primary liver cancer or metastases to the liver) may cause jaundice by causing obstruction of the bile duct. Even advanced cancer causes nonspecific signs and symptoms, such as right-upper-quadrant discomfort and tenderness, nausea, weight loss, and slight fever. Examination may reveal irregular, nodular, firm hepatomegaly, ascites, peripheral edema, a bruit heard over the liver, and a right-upper-quadrant mass.
With pancreatic cancer, progressive jaundice — possibly with pruritus — may be the only sign. Related early findings are nonspecific, such as weight loss and back or abdominal pain. Other signs and symptoms include anorexia, nausea and vomiting, fever, steatorrhea, fatigue, weakness, diarrhea, pruritus, and skin lesions (usually on the legs).
Cholangitis
Obstruction and infection in the common bile duct cause Charcot’s triad: jaundice, right-upper-quadrant pain, and high fever with chills. The patient may also report pruritus. Acholic or hypocholic stools may be present.
Cholecystitis
Cholecystitis produces nonobstructive jaundice in about 25% of patients. Biliary colic typically peaks abruptly, persisting for 2 to 4 hours. The pain then localizes to the right upper quadrant and becomes constant. Local inflammation or passage of stones to the common bile duct causes jaundice. Other findings include nausea, vomiting (usually indicating the presence of a stone), fever, profuse diaphoresis, chills, tenderness on palpation, a positive Murphy’s sign and, possibly, abdominal distention and rigidity.
Cholelithiasis
Cholelithiasis commonly causes jaundice and biliary colic. It’s characterized by severe, steady pain in the right upper quadrant or epigastrium that radiates to the right scapula or shoulder and intensifies over several hours. Accompanying signs and symptoms include nausea and vomiting, tachycardia, and restlessness. Occlusion of the common bile duct causes fever, chills, jaundice, clay-colored stools, and abdominal tenderness. After consuming a fatty meal, the patient may experience vague epigastric fullness and dyspepsia.
Cholestasis
With benign, recurrent intrahepatic cholestasis, the patient experiences prolonged attacks of jaundice (sometimes spaced several years apart) accompanied by pruritus. Other signs and symptoms are similar to those of hepatitis — fatigue, nausea, weight loss, anorexia, pale stools, and right-upper-quadrant pain.
Cirrhosis
With Laënnec’s cirrhosis, mild to moderate jaundice with pruritus usually signals hepatocellular necrosis or progressive hepatic insufficiency. Common early findings include ascites, weakness, leg edema, nausea and vomiting, diarrhea or constipation, anorexia, weight loss, and right-upper-quadrant pain. Massive hematemesis and other bleeding tendencies may also occur. Other findings include an enlarged liver and parotid gland, clubbed fingers, Dupuytren’s contracture, mental changes, asterixis, fetor hepaticus, spider angiomas, and palmar erythema. Males may exhibit gynecomastia, scanty chest and axillary hair, and testicular atrophy; females may experience menstrual irregularities.
With primary biliary cirrhosis, fluctuating jaundice may appear years after the onset of other signs and symptoms, such as pruritus that worsens at bedtime (commonly the first sign), weakness, fatigue, weight loss, and vague abdominal pain. Itching may lead to skin excoriation. Associated findings include hyperpigmentation; indications of malabsorption, such as nocturnal diarrhea, steatorrhea, purpura, and osteomalacia; hematemesis from esophageal varices; ascites; edema; xanthelasmas; xanthomas on the palms, soles, and elbows; and hepatomegaly.
Glucose-6-phosphate dehydrogenase deficiency
Acute intravascular hemolysis following ingestion of such drugs as quinine or aspirin causes jaundice, pallor, dyspnea, tachycardia, and malaise. Palpation may reveal splenomegaly and hepatomegaly.
Heart failure
Jaundice due to liver dysfunction occurs in patients with severe right-sided heart failure. Other effects include jugular vein distention, cyanosis, dependent edema of the legs and sacrum, steady weight gain, confusion, hepatomegaly, nausea and vomiting, abdominal discomfort, and anorexia due to visceral edema. Ascites is a late sign. Oliguria, marked weakness, and anxiety may also occur. If left-sided heart failure develops first, other findings may include fatigue, dyspnea, orthopnea, paroxysmal nocturnal dyspnea, tachypnea, arrhythmias, and tachycardia.
Hemolytic anemia (acquired)
Acquired hemolytic anemia may produce prominent jaundice along with dyspnea, fatigue, pallor, tachycardia, and palpitations. Rapid hemolysis causes chills, fever, irritability, headache, and abdominal pain; severe hemolysis causes signs of shock.
Hepatitis
Dark urine and clay-colored stools usually develop before jaundice in the late stages of acute viral hepatitis. Early systemic signs and symptoms vary and include fatigue, nausea, vomiting, malaise, arthralgias, myalgias, headache, anorexia, photophobia, pharyngitis, cough, diarrhea or constipation, and a low-grade fever associated with liver and lymph node enlargement. During the icteric phase (which subsides within 2 to 3 weeks unless complications occur), systemic signs subside, but an enlarged, palpable liver may be present along with weight loss, anorexia, and right-upper-quadrant pain and tenderness.
Pancreatitis (acute)
Pancreatitis can cause jaundice; however, this disorder’s primary symptom is usually severe epigastric pain that commonly radiates to the back. Lying with the knees flexed on the chest or sitting up and leaning forward brings relief. Early associated signs and symptoms include nausea, persistent vomiting, abdominal distention, and Turner’s or Cullen’s sign. Other findings include fever, tachycardia, abdominal rigidity and tenderness, hypoactive bowel sounds, and crackles.
Severe pancreatitis produces extreme restlessness; mottled skin; cold, diaphoretic extremities; paresthesia; and tetany — the last two being symptoms of hypocalcemia. Fulminant pancreatitis causes massive hemorrhage.
Sickle cell anemia
Hemolysis produces jaundice in patients with sickle cell anemia. Other findings include impaired growth and development, increased susceptibility to infection, life-threatening thrombotic complications and, commonly, leg ulcers, swollen joints (sometimes painful), fever, and chills. Bone aches and chest pain may also occur. Severe hemolysis may cause hematuria and pallor, chronic fatigue, weakness, dyspnea (or dyspnea on exertion), and tachycardia. The patient may also have splenomegaly. During a sickle cell crisis, the patient may have severe bone, abdominal, thoracic, and muscular pain; low-grade fever; and increased weakness, jaundice, and dyspnea.
Other causes
Drugs
Many drugs may cause hepatic injury and resultant jaundice. Examples include acetaminophen, phenylbutazone, I.V. tetracycline, isoniazid, hormonal contraceptives, sulfonamides, mercaptopurine, erythromycin estolate, niacin, troleandomycin, androgenic steroids, HMG-CoA reductase inhibitors, phenothiazines, ethanol, methyldopa, rifampin, and dilantin.
Treatments
Upper abdominal surgery may cause postoperative jaundice, which occurs secondary to hepatocellular damage from the manipulation of organs. Postoperative jaundice may lead to edema and obstructed bile flow from the administration of halothane or from prolonged surgery resulting in shock, blood loss, or blood transfusion. A surgical shunt used to reduce portal hypertension (such as a portacaval shunt) may also produce jaundice.

Hepatomegaly:
Medical causes
(Nursing: Interpreting Signs and Symptoms)
Amyloidosis.Amyloidosis is a rare disorder that may cause hepatomegaly and mild jaundice as well as renal, cardiac, and other GI effects.
Cirrhosis.Late in cirrhosis, the liver becomes enlarged, nodular, and hard. Other late signs and symptoms affect all body systems. Respiratory findings include limited thoracic expansion due to abdominal ascites, leading to hypoxia. Central nervous system findings include signs and symptoms of hepatic encephalopathy, such as lethargy, slurred speech, asterixis, peripheral neuritis, paranoia, hallucinations, extreme obtundation, and coma. Hematologic signs include epistaxis, easy bruising, and bleeding gums. Endocrine findings include testicular atrophy, gynecomastia, loss of chest and axillary hair, or menstrual irregularities. Integumentary effects include abnormal pigmentation, jaundice, severe pruritus, extreme dryness, poor tissue turgor, spider angiomas, and palmar erythema.
The patient may also develop fetor hepaticus, enlarged superficial abdominal veins, muscle atrophy, right upper quadrant pain that worsens when he sits up or leans forward, and a palpable spleen. Portal hypertension—elevated pressure in the portal vein—causes bleeding from esophageal varices.
Diabetes mellitus.Poorly controlled diabetes in overweight patients commonly produces fatty infiltration of the liver, hepatomegaly, and right upper quadrant tenderness along with polydipsia, polyphagia, and polyuria. These features are more common in type 2 than in type 1 diabetes. A chronically enlarged fatty liver typically produces no symptoms except for slight tenderness.
Granulomatous disorders.Sarcoidosis, histoplasmosis, and other such disorders commonly produce a slightly enlarged, firm liver.
Hepatic abscess.Hepatomegaly may accompany a fever (a primary sign), nausea, vomiting, chills, weakness, diarrhea, anorexia, an elevated right hemidiaphragm, and right upper quadrant pain and tenderness.
Hepatitis.In viral hepatitis, early signs and symptoms include nausea, anorexia, vomiting, fatigue, malaise, photophobia, a sore throat, a cough, and a headache. Hepatomegaly occurs in the icteric phase and continues during the recovery phase. Also, during the icteric phase, the early signs and symptoms diminish and others appear: liver tenderness, slight weight loss, dark urine, clay-colored stools, jaundice, pruritus, right upper quadrant pain, and splenomegaly.
Leukemia and lymphomas.Leukemia and lymphomas are proliferative blood cell disorders that typically cause moderate to massive hepatomegaly and splenomegaly as well as abdominal discomfort. General signs and symptoms include malaise, a low-grade fever, fatigue, weakness, tachycardia, weight loss, bleeding disorders, and anorexia.
Liver cancer.Primary liver tumors commonly cause irregular, nodular, firm hepatomegaly, with pain or tenderness in the right upper quadrant and a friction rub or bruit over the liver. Common related findings are weight loss, anorexia, cachexia, nausea, and vomiting. Peripheral edema, ascites, jaundice, and a palpable right upper quadrant mass may also develop. When metastatic liver tumors cause hepatomegaly, the patient's accompanying signs and symptoms reflect his primary cancer.
Mononucleosis (infectious).Occasionally, infectious mononucleosis causes hepatomegaly. Prodromal symptoms include a headache, malaise, and fatigue. After 3 to 5 days, the patient typically develops a sore throat, cervical lymphadenopathy, and temperature fluctuations. He may also develop stomatitis, palatal petechiae, periorbital edema, splenomegaly, exudative tonsillitis, pharyngitis and, possibly, a maculopapular rash.
Obesity.Hepatomegaly can result from fatty infiltration of the liver. Weight loss reduces the liver's size.
Pancreatic cancer.In pancreatic cancer, hepatomegaly accompanies such classic signs and symptoms as anorexia, weight loss, abdominal or back pain, and jaundice. Other findings include nausea, vomiting, a fever, fatigue, weakness, pruritus, and skin lesions (usually on the legs).
Pericarditis.In chronic constrictive pericarditis, an increase in systemic venous pressure produces marked congestive hepatomegaly. Distended jugular veins (more prominent on inspiration) are a common finding. The usual signs of cardiac disease typically are absent; other features include peripheral edema, ascites, fatigue, and decreased muscle mass.
Jaundice [Icterus]:
Medical causes
(Nursing: Interpreting Signs and Symptoms)
Carcinoma.Cancer of the ampulla of Vater initially produces fluctuating jaundice, mild abdominal pain, a recurrent fever, and chills. Occult bleeding may be its first sign. Other findings include weight loss, pruritus, and back pain.
Hepatic cancer (primary liver cancer or another cancer that has metastasized to the liver) may cause jaundice by causing obstruction of the bile duct. Even advanced cancer causes nonspecific signs and symptoms, such as right upper quadrant discomfort and tenderness, nausea, weight loss, and a slight fever. Examination may reveal irregular, nodular, firm hepatomegaly; ascites; peripheral edema; a bruit heard over the liver; and a right upper quadrant mass.
With pancreatic cancer, progressive jaundice—possibly with pruritus—may be the only sign. Related early findings are nonspecific, such as weight loss and back or abdominal pain. Other signs and symptoms include anorexia, nausea and vomiting, a fever, steatorrhea, fatigue, weakness, diarrhea, pruritus, and skin lesions (usually on the legs).
Cholangitis.Obstruction and infection in the common bile duct cause Charcot's triad: jaundice, right upper quadrant pain, and a high fever with chills.
Cholecystitis.Cholecystitis produces nonobstructive jaundice in about 25% of patients. Biliary colic typically peaks abruptly, persisting for 2 to 4 hours. The pain then localizes to the right upper quadrant and becomes constant. Local inflammation or passage of stones to the common bile duct causes jaundice. Other findings include nausea, vomiting (usually indicating the presence of a stone), a fever, profuse diaphoresis, chills, tenderness on palpation, a positive Murphy's sign and, possibly, abdominal distention and rigidity.
Cholelithiasis.Cholelithiasis commonly causes jaundice and biliary colic. It's characterized by severe, steady pain in the right upper quadrant or epigastrium that radiates to the right scapula or shoulder and intensifies over several hours. Accompanying signs and symptoms include nausea and vomiting, tachycardia, and restlessness. Occlusion of the common bile duct causes a fever, chills, jaundice, clay-colored stools, and abdominal tenderness. After consuming a fatty meal, the patient may experience vague epigastric fullness and dyspepsia.
Cirrhosis.With Laënnec's cirrhosis, mild to moderate jaundice with pruritus usually signals hepatocellular necrosis or progressive hepatic insufficiency. Common early findings include ascites, weakness, leg edema, nausea and vomiting, diarrhea or constipation, anorexia, weight loss, and right upper quadrant pain. Massive hematemesis and other bleeding tendencies may also occur. Other findings include an enlarged liver and parotid gland, clubbed fingers, Dupuytren's contracture, mental changes, asterixis, fetor hepaticus, spider angiomas, and palmar erythema. Males may exhibit gynecomastia, scanty chest and axillary hair, and testicular atrophy; females may experience menstrual irregularities.
With primary biliary cirrhosis, fluctuating jaundice may appear years after the onset of other signs and symptoms, such as pruritus that worsens at bedtime (commonly the first sign), weakness, fatigue, weight loss, and vague abdominal pain. Itching may lead to skin excoriation. Associated findings include hyperpigmentation; indications of malabsorption, such as nocturnal diarrhea, steatorrhea, purpura, and osteomalacia; hematemesis from esophageal varices; ascites; edema; xanthelasmas; xanthomas on the palms, soles, and elbows; and hepatomegaly.
Dubin-Johnson syndrome.With Dubin-Johnson syndrome, which is a rare, chronic inherited syndrome, fluctuating jaundice that increases with stress is the major sign, appearing as late as age 40. Related findings include slight hepatic enlargement and tenderness, upper abdominal pain, nausea, and vomiting.
Heart failure.Jaundice due to liver dysfunction occurs in patients with severe right-sided heart failure. Other effects include jugular vein distention, cyanosis, dependent edema of the legs and sacrum, steady weight gain, confusion, hepatomegaly, nausea and vomiting, abdominal discomfort, and anorexia due to visceral edema. Ascites is a late sign. Oliguria, marked weakness, and anxiety may also occur. If left-sided heart failure develops first, other findings may include fatigue, dyspnea, orthopnea, paroxysmal nocturnal dyspnea, tachypnea, arrhythmias, and tachycardia.
Hepatic abscess.Multiple liver abscesses may cause jaundice, but the primary effects are a persistent fever with chills and sweating. Other findings include steady, severe pain in the right upper quadrant or midepigastrium that may be referred to the shoulder; nausea and vomiting; anorexia; hepatomegaly; an elevated right hemidiaphragm; and ascites.
Hepatitis.Dark urine and clay-colored stools usually develop before jaundice in the late stages of acute viral hepatitis. Early systemic signs and symptoms vary and include fatigue, nausea, vomiting, malaise, arthralgia, myalgia, a headache, anorexia, photophobia, pharyngitis, a cough, diarrhea or constipation, and a low-grade fever associated with liver and lymph node enlargement. During the icteric phase (which subsides within 2 to 3 weeks unless complications occur), systemic signs subside, but an enlarged, palpable liver may be present along with weight loss, anorexia, and right upper quadrant pain and tenderness.
Pancreatitis (acute).Edema of the head of the pancreas and obstruction of the common bile duct can cause jaundice; however, the primary symptom of acute pancreatitis is severe epigastric pain that commonly radiates to the back. Lying with the knees flexed on the chest or sitting up and leaning forward brings relief. Early associated signs and symptoms include nausea, persistent vomiting, abdominal distention, and Turner's or Cullen's sign. Other findings include a fever, tachycardia, abdominal rigidity and tenderness, hypoactive bowel sounds, and crackles.
Severe pancreatitis produces extreme restlessness; mottled skin; cold, dia-phoretic extremities; paresthesia; and tetany—the last two being symptoms of hypocalcemia. Fulminant pancreatitis causes massive hemorrhage.
Sickle cell anemia.Hemolysis produces jaundice in the patient with sickle cell anemia. Other findings include impaired growth and development, increased susceptibility to infection, life-threatening thrombotic complications and, commonly, leg ulcers, swollen (painful) joints, a fever, and chills. Bone aches and chest pain may also occur. Severe hemolysis may cause hematuria and pallor, chronic fatigue, weakness, dyspnea (or dyspnea on exertion), and tachycardia. The patient may also have splenomegaly. During a sickle cell crisis, the patient may have severe bone, abdominal, thoracic, and muscular pain; a low-grade fever; and increased weakness, jaundice, and dyspnea.
Other causes
Drugs.Many drugs may cause hepatic injury and resultant jaundice. Examples include acetaminophen, phenylbutazone, I.V. tetracycline, isoniazid, hormonal contraceptives, sulfonamides, mercaptopurine, erythromycin estolate, niacin, troleandomycin, androgenic steroids, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, phenothiazines, ethanol, methyldopa, rifampin, and dilantin.
Treatments.Upper abdominal surgery may cause postoperative jaundice, which occurs secondary to hepatocellular damage from the manipulation of organs, leading to edema and obstructed bile flow; from the administration of halothane; or from prolonged surgery resulting in shock, blood loss, or blood transfusion.
A surgical shunt used to reduce portal hypertension (such as a portacaval shunt) may also produce jaundice.
