Strongyloidiasis: prevalence, risk factors, clinical and laboratory features among diarrhea patients in Ibadan Nigeria.

Abstract

Strongyloidiasis is a parasitic infection caused by Strongyloides stercoralis. The infection is usually mild or asymptomatic in normal immunocompetent individuals, but could be very severe or even fatal due to hyper infection in individuals who are immunosuppressed. This study aimed at determining the prevalence, risk factors and features of strongyloidiasis among diarrhea patients in Ibadan. This is a descriptive cross-sectional study of diarrhea patients from a teaching hospital, three major government hospitals and one mission hospital in Ibadan. Self administered questionnaire, clinical assessment and laboratory investigations were used to confirm health status and presence of S. stercoralis. Diagnosis was made by microscopic examination of stool in saline preparation and formol-ether concentration. One thousand and ninety patients, (562 (51.6%) males and 528 (48.4%) females) consisting 380 (34.9%) children and 710 (65.1%) adults who had diarrhea were studied. The prevalence rate for the parasite among diarrhea patients was 3.0%. While the risk factor for infection remains contact with contaminated soil, malnutrition, steroid therapy, HIV/AIDS, lymphomas, tuberculosis, and chronic renal failure. Others are maleness, institutionalism and alcoholism. Predominant clinical presentations are abdominal pain, chronic diarrhea, and bloating and weight loss, Strongyloides stercoralis should be considered in diarrhea patients who are either malnourished or immunosuppressed.
