Abstract/OtherAbstract:
Enteric pathogens associated with chronic diarrhoea in HIV-positive patients were studied. The study was conducted during January 1995-December 1998. Stool specimens from all diarrhoea patients (n = 26) were examined microscopically for ova and parasites using wet preparations and stained smears. Stool samples from diarrhoea patients were also cultured on appropriate media to isolate enteric bacterial pathogens. Of the 59 patients, 26 (44%) had prolonged diarrhoea for more than 4 weeks. Enteric pathogens were detected in 19 (73%) of the 26 patients: 17 patients harboured a single pathogen, and 2 patients had mixed pathogens. The detection rate of emerging parasites, including Isospora, Cryptosporidium, Blastocystis hominis, and Strongyloides stercoralis as a single agent, was significantly higher than conventional pathogens (50% vs 19.2%; p < 0.05). Only one patient harboured both conventional and emerging pathogens (Entamoeba histolytica and Cryptosporidium). Isospora belli was detected in 8 (31%) of the 26 diarrhoea patients: in 7 (27%) patients as a single agent and in one patient with S. stercoralis. Cryptosporidium was identified in 3 (11%) diarrhoea patients: in 2 (8%) patients as a single agent and in one patient with E. histolytica, followed by B. hominis in 2 (8%) patients. E. histolytica was most commonly isolated (3/26; 11.5%), followed by Giardia lamblia, enteropathogenic Escherichia coli, and Campylobacter jejuni (one patient each). Parasitic pathogens were frequently associated with HIV-positive patients with diarrhoea in northern India. I. belli was the most frequent parasite isolated, followed by Cryptosporidium. Stools of all HIV-positive patients with diarrhoea should thoroughly be investigated to identify aetiologic agents for proper management.
