Allergic purpuras: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

Characteristic skin lesions of allergic purpura are purple, macular, ecchymotic, and of varying size. They’re caused by vascular leakage into the skin and mucous membranes. (See Purpuric lesions.) The lesions usually appear in symmetric patterns on the arms, legs, and buttocks and are accompanied by pruritus, paresthesia and, occasionally, angioneurotic edema. In children, skin lesions are generally urticarial and expand and become hemorrhagic. Scattered petechiae may appear on the legs, buttocks, and perineum.

Henoch-Schönlein syndrome commonly produces transient or severe colic, tenesmus (spasmodic contraction of the anal sphincter) and constipation, vomiting, and edema or hemorrhage of the mucous membranes of the bowel, resulting in GI bleeding, occult blood in the stool and, possibly, intussusception. Such GI abnormalities may precede overt, cutaneous signs of purpura. Musculoskeletal symptoms, such as rheumatoid pains and periarticular effusions, mostly affect the legs and feet.

In 25% to 50% of patients, allergic purpura is associated with GU signs and symptoms: nephritis; renal hemorrhages that may cause microscopic hematuria and disturb renal function; bleeding from the mucosal surfaces of the ureters, bladder, or urethra; and, occasionally, glomerulonephritis. Also possible are moderate and irregular fever, headache, anorexia, and localized edema of the hands, feet, or scalp.

Allergic rhinitis: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

In seasonal allergic rhinitis, the key signs and symptoms are paroxysmal sneezing, profuse watery rhinorrhea, nasal obstruction or congestion, and pruritus of the nose and eyes. It’s usually accompanied by pale, cyanotic, edematous nasal mucosa; red and edematous eyelids and conjunctivae; excessive lacrimation; and headache or sinus pain. Some patients also complain of itching in the throat and malaise.

In perennial allergic rhinitis, conjunctivitis and other extranasal effects are rare, but chronic nasal obstruction is common. In many cases, this obstruction extends to eustachian tube obstruction, particularly in children.

In both types of allergic rhinitis, dark circles may appear under the patient’s eyes (“allergic shiners”) because of venous congestion in the maxillary sinuses. The severity of signs and symptoms may vary from season to season and from year to year.

Latex allergy: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

Early signs that a life-threatening hypersensitivity reaction may be occurring include hypotension, tachycardia, and oxygen desaturation. Other clinical findings include urticaria, flushing, bronchospasm, difficulty breathing, pruritus, palpitations, abdominal pain, and syncope. Mild signs and symptoms may include itchy skin, swollen lips, nausea, diarrhea, and red, swollen, teary eyes.

Urticaria and angioedema: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

The characteristic features of urticaria are distinct, raised, evanescent (temporary) dermal wheals surrounded by an erythematous flare. These lesions may vary in size. In cholinergic urticaria, the wheals may be tiny and blanched, surrounded by erythematous flares.

Angioedema characteristically produces nonpitted swelling of deep subcutaneous tissue, usually on the eyelids, lips, genitalia, and mucous membranes. These swellings don’t usually itch but may burn and tingle.

anaphylaxis: Signs and symptoms
(Handbook of Diseases)

An anaphylactic reaction produces sudden physical distress within seconds or minutes after exposure to an allergen. A delayed or persistent reaction may occur up to 24 hours later. The severity of the reaction is inversely related to the interval between exposure to the allergen and the onset of symptoms. Usually, the first signs and symptoms include a feeling of impending doom or fright, weakness, sweating, sneezing, shortness of breath, nasal pruritus, urticaria, and angioedema, followed rapidly by symptoms in one or more target organs.

Systemic effects

Cardiovascular signs include hypotension, shock, and sometimes cardiac arrhythmias, which, if untreated, may precipitate circulatory collapse.

Respiratory signs and symptoms can occur at any level in the respiratory tract and commonly include nasal mucosal edema, profuse watery rhinorrhea, itching, nasal congestion, and sudden sneezing attacks. Edema of the upper respiratory tract, resulting in hypopharyngeal and laryngeal obstruction (hoarseness, stridor, and dyspnea), is an early sign of acute respiratory failure, which can be fatal.

GI and genitourinary signs and symptoms include severe stomach cramps, nausea, diarrhea, and urinary urgency and incontinence.

Article Excerpts About Symptoms of Allergies:

Something in the Air Airborne Allergens: NIAID (Excerpt)

The signs and symptoms are familiar to many:

In people who are not allergic, the mucus in the nasal passages simply moves foreign particles to the throat, where they are swallowed or coughed out. But something different happens to a person who is sensitive to airborne allergens.

As soon as the allergen lands on the mucous membranes lining the inside of the nose, a chain reaction occurs that leads the mast cells in these tissues to release histamine and other chemicals. These powerful chemicals contract certain cells that line some small blood vessels in the nose. This allows fluids to escape, which causes the nasal passages to swell, resulting in nasal congestion.

Histamine also can cause sneezing, itching, irritation, and excess mucus production, which can result in allergic rhinitis (runny nose). Other chemicals made and released by mast cells, including cytokines and leukotrienes, also contribute to allergic symptoms. (Source: excerpt from Something in the Air Airborne Allergens: NIAID)

Allergies: NWHIC (Excerpt)

Common symptoms for allergies include:

• Sneezing, often accompanied by a runny or clogged nose

• Coughing and postnasal drip

• Itching eyes, nose, and throat

• Watering eyes

• Allergic dermatitis: an itchy rash. (The most common skin condition in children ages 11- 14.)

• Allergic shiners: dark circles under the eyes caused by increased blood flow near the sinuses

• Allergic salute: persistent upward rubbing of the nose that causes a crease mark on the nose

• Conjunctivitis: an inflammation of the membrane that lines the eyelids, causing red-rimmed, swollen eyes, and crusting of the eyelids. Commonly known as pink eye.

Allergies: NWHIC (Excerpt)

Allergy symptoms often resemble a cold, however the cold seems to linger. Symptoms include a runny nose, itchy eyes, headaches, and sinus pain. Usually there is no fever. It is important to see a doctor about any respiratory symptoms that last longer than a week or two. Properly trained physicians can recognize patterns of potential allergens.
