The epidemiology of intestinal microsporidiosis in patients with HIV/AIDS in Lima, Peru.

We studied microsporidiosis in human immunodeficiency virus-positive patients in 2 Lima hospitals. Of 2652 patients, 66% were male, 6% received antiretroviral therapy (ART), and the median CD4 lymphocyte count was 131 cells/microL. Sixty-seven patients (3%) had microsporidiosis; stool specimens from 56 were identified as having Enterocytozoon bieneusi of 10 different genotypes. The 2 most common genotypes, Peru-1 and Peru-2, were not associated with significant increases in chronic diarrhea; other genotypes were associated with a 4-fold increased risk. Risk factors for E. bieneusi infection segregated by genotype: contact with duck or chicken droppings and lack of running water, flush toilet, or garbage collection with genotype Peru-1 and watermelon consumption with other genotypes. Shortened survival was associated with low CD4 lymphocyte count (P<.0001), no ART (P<.0001), and cryptosporidiosis (P=.004) but not with microsporidiosis (P=.48). Our data suggest the possibility of zoonotic E. bieneusi transmission and an association with poor sanitary conditions.[1]
