[Epidemiology of anguillulosis among public school children in Abidjan, Cote d'Ivoire]. / Epidémiologie de l'anguillulose chez les enfants scolarisés à l'école publique à Abidjan (Côte d'Ivoire).

PURPOSE: Strongyloides stercoralis is a neglected soil-transmitted helminth species. In Cote d'Ivoire, as elsewhere, there is a lack of parasitologic and epidemiologic data pertaining to this parasite. The purpose of this study was to evaluate the prevalence and impact of sociodemographic factors on anguillulosis among public school children in Abidjan, Cote d'Ivoire. METHODS: Testing for Strongyloides stercoralis was performed in a random sample of 411 children from 10 public primary schools in Abidjan. Detection methods included direct examination of stool smears, the Baermann test and helminth coproculture study. RESULTS: The overall prevalence of anguillulosis was 2.7% (N=411) (IC95% = 1.34-4.73). The M/F sex-ratio was 1. No correlation was found between prevalence and sex (p = 0.12). Prevalence was higher among children who reported contact with swamps and rivers (respectively 80% and 7.9%) than those who did not report such contact (respectively 1.7% and 1.5%) (p <0.01). CONCLUSION: Contact with swamps and rivers is correlated with an increase in anguillulosis prevalence. Avoiding these areas and proper sanitation could help to reduce the prevalence of anguillulosis in Abidjan.

Oropharyngeal candidiasis prevalence among HIV-infected patients at the teaching hospital of Treichville (Abidjan, Côte d'Ivoire).

AIM OF THE STUDY: The aim of this study was to determine the mycological profile of oropharyngeal candidiasis among HIV-infected patients from Internal Medicine, Infectious and Tropical Diseases, and Pneumo-Phthisiology Diseases departments of the Teaching Hospital of Treichville in Abidjan, Côte d'Ivoire. PATIENTS AND METHODS: This was a cross-sectional study carried out on patients with lesions suggestive of oropharyngeal candidiasis from October 2010 to April 2011. Oral swabs were cultured, and Candida species were identified using a germ tube test, a chlamydospore formation assay, and the API 20C system. RESULTS: A total of 286 patients were included, among whom 99.1% were infected with HIV. The prevalence of oropharyngeal candidiasis was 79.4% (CI95%=74.4-83.8). Five different species of Candida were identified, with the predominant species being Candida albicans (95.2%). Most affected patients were female (54.6%, P<0.0001) between the ages of 30 and 45 (78.4%, P<0.0001). The most lesion types observed were thrush (87.8%). Patients infected with HIV1 (95.6%), with a primary school level of education (52.8%), under antiretroviral therapy (88.5%) and with tuberculosis as an associated pathology (62.5%) were the most commonly affected. Patients were mostly under ART first line treatment (86.4%) and at the beginning of the treatment (86.4%). CONCLUSION: Oropharyngeal candidiasis is frequent among HIV-infected patients. Better and early management of this vulnerable population should allow for a reduction in the high prevalence observed.
