High Clostridium difficile Infection among HIV-Infected Children with Diarrhea in a Tertiary Hospital in Mwanza, Tanzania

الملخص EN

Clostridium difficile causes a million of illnesses each year worldwide and can affect people of all ages.

Limited data exist on the prevalence of C.

difficile infections (CDI) among children below five years of age in developing countries.

This study is aimed at determining the prevalence, associated factors, and outcome of the Clostridium difficile infection among children with diarrhea attending a tertiary hospital in Mwanza, Tanzania.

Stool samples were collected and cultured anaerobically to isolate Clostridium difficile, followed by C.

difficile toxin A and B assay and ribotyping.

A total of 301 children with diarrhea were enrolled.

A total of 22 (7.31%, 95% CI: 0.89-0.95) nonrepetitive stool samples were positive for Clostridium difficile.

Eighteen (81%) of C.

difficile isolates were toxigenic, and 16 (72.7%) had unknown ribotypes.

Independent predictors of positive C.

difficile were as follows: positive HIV status, hospital stay of more than four days, high stool leukocyte count, and watery stool.

Clostridium difficile-positive children had significantly higher median duration of the diarrhea than those without C.

difficile.

Clinicians should consider C.

difficile as a possible cause of diarrhea in children living in developing countries and institute appropriate management to prevent associated morbidities and mortalities.

Furthermore, there is a need of joint effort to improve C.

difficile diagnosis and surveillance in developing countries to establish the unknown epidemiology of CDI in these countries.
