Unexpected rapid symptom response after praziquantel to intestinal Schistosoma mansoni symptoms: A case report from Rwanda

Abstract

The clinical effect of praziquantel on chronic intestinal schistosomiasis in the literature is lacking. We report a patient who presented with 3 years of non-specific abdominal pain and underwent colonoscopy, which revealed colon polyps that, on biopsy, were confirmed to be due to Schistosoma mansoni. The patient was given a single dose of praziquantel, and his abdominal symptoms disappeared within 24 h. Patients with abdominal pain in the setting of chronic Schistosoma infection should be given praziquantel and assess response clinically.
