Cryptosporidium infection among hemodialysis patients attending to the dialysis center at Kosti Teaching Hospital, Sudan.

Cryptosporidiosis is an illness caused by a protozooan parasite Cryptosporidium. Cryptosporidium species are an opportunistic pathogens cause a diarrheal disease worldwide, and can be more severe in immunocompromized patients. Until now, a little data have been available on its prevalence rate among haemodialysis patients in Sudan. Therefore, this article was designed to examine the prevalence of Cryptosporidium among hemodialysis Sudanese patients attending hemodialysis center at Kosti Teaching Hospital. A case-control study including one-hundred and twelve hemodialysis patients between November 2016 and January 2017 have been conducted. For the control group, we include one-hundred and twelve normal population. A total of two-hundred and twenty-four stool samples were collected. The stool samples were processed and examined using the modified Ziehl-Neelsen (ZN) staining method. High Cryptosporidium prevalence of 14/112 (12.5%) was detected in hemodialysis patients compare to the normal individuals 3/112 (2.7%). There was no correlation between the prevalence of Cryptosporidium infection with the age, sex, and the duration of dialysis (P>0.05). Therefore, an early detection and prompt treatment of Cryptosporidium infected hemodialysis patients is crucial.
