[Chronic diarrhea and Cryptosporidium in diabetic patients with normal lymphocyte subpopulation. 2 case reports].

Two cases of diabetic patients with normal TCD4+ cell count with chronic diarrhoea and Cryptosporidium are described herein. In both cases serologic tests for HIV were negative. The fact that these patients developed a pathology usually seen in presence of low TCD4+ cell counts suggests that some immune defect other than cellular might be involved in the pathogenesis of this infection. Authors concluded that intentional search for Cryptosporidium should be considered in the study of the diabetic patient with chronic diarrhoea.
