Pulmonary cryptosporidiosis in HIV negative, immunocompromised host.
Cryptosporidia are intestinal spore forming protozoa, which cause intracellular infections, predominantly in the epithelial cells of the intestine. Extra-intestinal infections with Cryptosporidium parvum have been rarely reported. However, a few reports of pulmonary cryptosporidiosis in HIV/AIDS cases have been mentioned in literature. In immunocompromised individuals who do not have HIV-related disease, Cryptosporidiosis has been rarely reported. We present a case of respiratory infection caused by C. parvum. The patient was a 10-year-old child with nephrotic syndrome and was receiving corticosteroids for 6 months. The child had history of low-grade fever, breathlessness and cough with expectoration of 3 months duration. The patient was nonreactive for HIV, and there was no evidence of primary immunodeficiency. Major serum immunoglobulins (IgG, IgA, and IgM) were in normal range. Simultaneous gastrointestinal involvement with C. parvum was observed.
