[Review of 2 cases of severe infection with pulmonary Strongyloides stercoralis].

To improve the understanding of pulmonary Strongyloides stercoralis.Two paients were diagnosed with severe infection with pulmonary Strongyloides stercoralis by respiratory ICU of Xiangya Hospital. The clinical manifestations, laboratory tests, imaging and pathological data were analyzed. Another 87 cases in the literature were reviewed from 1973 to 2013.In the 2 cases, digestive symptoms were the first symptom and Strongyloides stercoralis was found in the lungs. Eosinophils was detected in the 13 death cases by blood routine examination, with 10 cases≤0.05× 10(9)/L.The farmers were the main infected people. Patients with basic diseases or with immunosuppression due to long-term glucocorticoid treatment tend to infect and even die after the infection with Strongyloides stercoralis. Eosinophil granulocyte reduction shows poor prognosis, which needs early diagnosis and treatment.
