Strongyloidiasis of the lungs
Introduction
Introduction to pulmonary faecal nematode A. faecalis generally parasitizes the submucosal layer of the human small intestine. It can also cause disseminated damage to the lungs and other internal organs in cases of severe infection or low immune function. The pulmonary faecal roundworm disease is caused by the filamentous mites of the roundworm of the genus A. faecalis invading the skin or mucous membrane, through the lymphatic or venous system, from the right heart to the lungs. It develops into a child worm in 3 to 30 days, and a small number of worms are in the lungs. Or mature in the bronchi, most of the worms penetrate the lungs and capillaries into the alveoli caused by a series of respiratory symptoms. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: respiratory infection Complications: pneumonia meningitis brain abscess
Cause
Cause of pulmonary faecal nematode
(1) Causes of the disease
A. faecalis generally parasitizes the submucosal layer of the human small intestine. It can also cause disseminated damage to the lungs and other internal organs in cases of severe infection or low immune function.
(two) pathogenesis
The pulmonary faecal roundworm disease is caused by the filamentous mites of the roundworm of the genus A. faecalis invading the skin or mucous membrane, through the lymphatic or venous system, from the right heart to the lungs. It develops into a child worm in 3 to 30 days, and a small number of worms are in the lungs. Or mature in the bronchi, most of the worms penetrate the lungs and capillaries into the alveoli caused by a series of respiratory symptoms.
Prevention
Pulmonary faecal disease prevention
Focus on strengthening publicity, promoting the harmless treatment of manure, reforming fertilization and farming methods, and conducting regular census and general treatment in epidemic areas.
Complication
Pulmonary faecal worm complications Complications pneumonia meningitis brain abscess
Severe pneumonia, meningitis, brain abscess.
Symptom
Pulmonary faecal disease symptoms common symptoms pimples dyspnea
Most of the clinical manifestations are mild, can be expressed as small local bleeding points, papules, transitional linear or banded urticaria, allergic bronchitis, lobular pneumonia or asthma, such as with serious diseases (such as leukemia) Malnutrition or low immunity (such as long-term use of glucocorticoids), severe diffuse infection and self-infection, patients often have fever, severe cough, cough, hemoptysis, shortness of breath, difficulty breathing, asthma and other symptoms, can also With multiple internal organs involved and systemic poisoning and other symptoms, even a short time to death, X-ray chest X-ray can be a bit like, small pieces, cord-like localized or diffuse inflammatory shadow, laboratory examination of peripheral blood leukocytes often Increased, up to 20 × 109 / L, eosinophils generally 25% to 30%, up to 70% to 80%, serum total IgE levels increased by 50%, serum IgG and IgE 90 for filamentous sputum antigen % patients are positive. If the female is parasitic in the bronchial epithelium, rod-shaped mites, filamentous mites, worms, adults and eggs can be found in the fresh sputum.
Examine
Examination of pulmonary faecal roundworm disease
White blood cell laboratory examination of peripheral blood leukocytes often increased, up to 20 × 109 / L, eosinophils generally in 25% ~ 30%, up to 70% ~ 80%, serum total IgE levels increased by 50%, for filamentous Serum IgG and IgE in sputum antigens are positive in 90% of patients. In the sputum, parasites and eggs are found. For example, females are parasitic on the bronchial epithelium. In the fresh sputum, rod-shaped mites, filamentous mites, worms, adults and eggs can be found. Can be diagnosed.
X-ray films can be a bit shape, small pieces, cord-like limitations or diffuse inflammatory shadows.
Diagnosis
Diagnosis and diagnosis of round worm disease in the lung
The diagnosis of lung damage in faecal roundworm disease needs to be comprehensively analyzed according to epidemiology, clinical manifestations and laboratory tests, but the lung faecal nematodes need fresh feces to find pathogens to diagnose.
Pneumocystis should be distinguished from bronchial pneumonia, bronchial asthma, tuberculosis, rheumatic fever and so on.
