Chronic eosinophilic pneumonia

Chronic eosinophilic pneumonia
This is a parasitic disease (hookworm, roundworm, etc.) and drug (nitrofurantoin due, etc.) caused by allergic, for pulmonary eosinophil infiltration consumption of a disease.

Interstitial lung, pulmonary and bronchial fine with leukocyte infiltration, mainly mature eosinophils, a small amount of tissue cells and lymphocytes, alveolar cells seen in eosinophilic particles containing a sharp edge and crystallization of the multinucleated giant cells, the disease-oriented The features. Some of the pulmonary blood vessels, is a pulmonary vein of vascular inflammation, and sometimes see multinucleated giant cells and eosinophilic granuloma.

Patients with more common in young and middle-aged women, fever, weight loss, night sweats. Cough and more present phlegm, with short breath and hemoptysis. Peripheral blood eosinophil cells in more than 20 to 70 percent.

Chest X-ray showed that not a paragraph or leaves around the patchy distribution of the shadow, often for bilateral distribution. Glucocorticoid treatment within 48 h after symptoms and chest film can quickly disappear. In the same part can be repeated, a few years later changed into a honeycomb or fibrosis.

According to the typical history, course and X-ray and other diagnosis can be made. However, eosinophil and other lung diseases associated with increased need for identification.

Simple pulmonary eosinophil infiltration of parasites and drug also caused by allergic, interstitial lung, alveolar walls and terminal bronchiole wall eosinophil infiltration stove, no clinical symptoms, a small amount of mucus Qingke Sputum, chest X-ray showed small pieces or large fuzzy shadow of a migratory. General without treatment.

Asthma pulmonary eosinophilia of aspergillosis is mainly caused by the repeated asthma, allergic as the characteristics of. And the alveolar interstitial more of eosinophil infiltration, bronchiectasis thin end of the present phlegm and full of thick, can find true mycelium. Chest X-ray more common in the upper Liangfei migration shadow. With glucocorticoid and antifungal treatment of asthma can control, the shadow disappeared.

Tropical eosinophilia of the infection, such as Brugia caused by pulmonary eosinophil cells and infiltration, the distribution was bronchial pneumonia, bronchial necrosis with small and eosinophilic abscess. Attack of asthma-like drama of cough, sputum less difficult Ke Chu, the sense of chest tightness, fatigue, Nacha. X chest film showing two Fei Wenli increased, with miliary or fuzzy shadow, may have chronic fibrosis. Filarial the anti-drug treatment, ease the symptoms a few days, the slow disappearance of lung disease.

Glucocorticoid treatment significantly, and often return to normal, due to stopping recurrence easier, it takes the whole course of treatment in more than a year.
