Glossary for Liver symptoms

Medical terms related to Liver symptoms or mentioned in this section include:

  • $3-alpha-Hydroxyacyl-CoA Dehydrogenase Deficiency$: A rare inherited form of biochemical disorder characterized by the deficiency of a particular enzyme (3-Hydroxyacyl-CoA Dehydrogenase). The enzyme deficiency only affects certain body tissues, in particular the skeletal muscles. The lack of enzyme activity prevents some fats being converted into energy. Symptoms tend to be exacerbated during fasting as during fasting, the body tries to rely more heavily on fats for energy. Fatty acids that are not completely metabolized due to the enzyme deficiency may build up in various organs and cause serious complications.
  • $3-alpha-hydroxyacyl-coenzyme A dehydrogenase deficiency$: A rare inherited form of biochemical disorder characterized by the deficiency of a particular enzyme (3-Hydroxyacyl-CoA Dehydrogenase). The enzyme deficiency only affects certain body tissues, in particular the skeletal muscles. The lack of enzyme activity prevents some fats being converted into energy. Symptoms tend to be exacerbated during fasting as during fasting, the body tries to rely more heavily on fats for energy. Fatty acids that are not completely metabolized due to the enzyme deficiency may build up in various organs and cause serious complications.
  • $3-methylglutaconic aciduria, type 4$: A rare genetic disorder where the body's cells are unable to make sufficient energy resulting in an accumulation in the body of 3-methylglutaconic acid. Type 4 is characterized by symptoms which overlap type 1 and 3.
  • $4-Alpha-hydroxyphenylpyruvate hydroxylase deficiency$: A very rare metabolic disorder where a deficiency of a particular enzyme results in the urinary excretion of a chemical called hawkinsin. Symptoms start once the infant is weaned off breast milk.

The body has enough iron but the red blood cells are unable to utilize it in a normal manner and anemia results. The red blood cells become overloaded with iron and are unable to carry out their normal functions. Some forms of sideroblastic anemia are inherited but most tend to be acquired due to such things as exposure to toxins and certain drugs, leukemia, inflammatory conditions such as rheumatoid arthritis and nutritional deficiencies (e.g. copper and pyridoxine deficiency). Inherited forms usually appear in childhood whereas acquired forms usually occur in adulthood.

Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. There are three main subtypes (L1, L2 and L3) which are differentiated by the appearance of the cancerous cells: L1 is characterized by small, uniform cancer cells with a round nucleus and very little cytoplasm. L1 has a better prognosis than L2. L1 is the main form in children (about 85%) but is less common in adults (about 30%).
  • Leukemia, Lymphocytic, Acute, L2: Acute lymphocytic leukemia is a cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. There are three main subtypes (L1, L2 and L3) which are differentiated by the appearance of the cancerous cells: L2 is characterized by larger cells, an irregular-shaped nucleus, more cytoplasm and significant variation between cells. L2 has a poorer prognosis than L1. L2 is the main form in adults (about 65%) but is less common in children (about 15%).
  • Leukemia, Lymphocytic, Acute, L3: Acute lymphocytic leukemia is a relatively aggressive cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. There are three main subtypes (L1, L2 and L3) which are differentiated by the appearance of the cancerous cells. L3 is quite uncommon but is very similar to Burkitt's lymphoma - in fact, they may be considered the same disease with different manifestations.

  • Leukemia, Myeloid, Chronic-Phase: Myeloid leukemia is a form of cancer where the bone marrow makes too many myeloid cells (granulocytes and their precursors) in the bone marrow which accumulates in the blood and eventually invades various parts of the body. The chronic phase of myeloid leukemia usually involves few if any symptoms. This is the early stage of the disease and without treatment it generally progresses to the accelerated phase of the condition. The majority of patients diagnosed with myeloid leukemia are diagnosed during the chronic phase.
  • Leukemia, Myeloid, Philadelphia-Negative: Acute lymphocytic leukemia is a relatively aggressive cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. The Philadelphia negative form of the condition is not associated with a genetic mutation. It is distinguished from the positive form by the clinical course which is initially the same but progresses to eventual bone marrow failure without a distinct increase in blast cells. Other differences include poor response to chemotherapy, lower white blood cell counts, greater monocytosis, less basophilia, lower bone marrow myeloid to erythroid ratio and increased likelihood of developing thrombocytopenia. Philadelphia negative patients also tend to be older and median survival rates tend to be poorer.
  • Leukemia, Myeloid, Philadelphia-Positive: Acute lymphocytic leukemia is a relatively aggressive cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. The Philadelphia form of myeloid leukemia carries the poorest prognosis of all the different types. It involves an acquired genetic mutation which results in the production tyrosine kinase which causes too many white blood cells to be produced which results in a shortage of other blood cell types. Treatment is aimed at inhibiting the production of tyrosine kinase.
