Case report: Diagnosis of cryptosporidiosis in renal transplantation in a low-prevalence setting

Abstract

In high prevalence settings, cryptosporidiosis is commonly implicated as a cause of a gastroenteritis syndrome in the organ transplant population. Stool microscopy is predominant diagnostic modality. Therapeutic options in this group of patients are limited, making their management exceptionally challenging. We describe a case of a renal transplant recipient with cryptosporidiosis confirmed by the stool FilmArray gastrointestinal panel (GIP) nucleic acid-based assay and stool microscopy, describe our institutional experience in diagnosing cryptosporidiosis in a low-prevalence setting, and review the available literature on management of this condition in the organ transplant population. In a low-prevalence setting, the GIP can serve as a rapid screening tool in the diagnosis of cryptosporidiosis.
