Eosinophilia

Introduction to eosinophilia The occurrence of eosinophilia is characterized by an immune response: initial stimulation with a snail (line) insect can cause a primary and relatively low level of response; however, repeated stimulation results in an amplified or secondary eosinophilic response. . basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: Asthma

Causes of eosinophilia

Common causes of this disease are:

1 Parasitic diseases such as aphids, hookworms and schistosomiasis.

2 allergic diseases such as bronchial asthma and urticaria.

3 skin diseases such as psoriasis, eczema and exfoliative dermatitis.

4 blood diseases and tumors, such as lymphoma, eosinophilic leukemia, chronic myeloid leukemia, metastatic cancer.

5 systemic lupus erythematosus and other autoimmune diseases.

6 certain pulmonary-derived eosinophilia.

7 certain drugs, such as cyanine, streptomycin, sulfonamides.

8 other, such as eosinophilic gastroenteritis and endocarditis and lymphogranuloma.

There are also eosinophilic syndromes of unknown cause.

Eosinophilia prevention

To prevent the cause of the disease, if the underlying cause is not detected, the patient's complications should be followed up. Patients with organ-accumulating eosinophilia should be treated regardless of the degree of organ involvement. The purpose is to Reduce eosinophils and block the effects of eosinophil products.

Eosinophilic complications Complications asthma

Common complications of this disease are infections, common clinical symptoms: low fever, fever, fatigue, nodules, cough, asthma, wheezing, chest pain, itching, wheezing.

Symptoms of eosinophilia Common symptoms Nodules, weakness, wheezing, wheezing, itching, chest pain, low fever

Common clinical symptoms: low fever, fever, fatigue, nodules, cough, asthma, wheezing, chest pain, itching, wheezing.

Diagnosis: should focus on travel and allergies and the history of the use of drugs, through physical examination and chest X-ray, ECG, urine, liver, kidney function tests may lead to the diagnosis of the underlying cause and the estimation of organ damage, depending on the clinical Special diagnostic tests for performance, including examination of fecal eggs and parasites, and serological examination of parasitic diseases and connective tissue diseases, may not have a diagnosis of the stage of the intestinal life cycle during stool examination, so stool examination Negative does not rule out the cause of the parasite (such as Trichinella requires muscle biopsy, visceral aphid migration and filarial infection for other tissue biopsy), duodenal aspiration to exclude special parasites (such as the genus) The cause is necessary.

Increased serum vitamin B12 and/or decreased white blood cell alkaline phosphatase may suggest a underlying disease of myeloproliferative disease, bone marrow smears, biopsy and cytogenetics may be helpful in diagnosis, especially in the presence of immature cells in peripheral blood.

Examination of eosinophilia

1. Physical examination.

2. Chest X-ray, ECG, urine, liver, kidney function tests.

3. Special diagnostic tests, including examination of fecal eggs and parasites, and serological examination of parasitic diseases and connective tissue diseases.

4. Serum vitamin B12 and / or leukocyte alkaline phosphatase examination.

Diagnosis and identification of eosinophilia

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

This disease should be distinguished from eosinophilic leukemia.
