Physiopathologie de la candidose oropharyngée au cours de l’infection par le VIH

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% (CI_95%=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.

OBJECTIVES

This study had for aim to identify the clinical status and the level of immuno-deficiency of HIV-infected patients on their first visit.

METHODS

One hundred and thirty-six HIV+ patients were prospectively evaluated from November 1, 2001 to May 31, 2002.

RESULTS

One hundred and thirty-four were infected with HIV1 and two with HIV2. The mean age on the first consultation was 37 +/- 2 years. The m/w sex ratio was 0.9. 46.3% were stage C. The main clinical symptoms were: weight loss (88%), fever (80%), cough (71%), diarrhea (51%). BMI was normal in 70% and KI > or =80% in 57% of the cases but immuno-deficiency was severe with CD4 cells count <200 per mm3 in 69%. The main diseases were digestive candidiasis (53%), pneumonia (18%), tuberculosis (12%), non-determined pneumonia (29%), prurigo (20%), zona (16%), cryptosporidiosis (4%), cerebral toxoplasmosis (3%), and Kaposi's sarcoma (1%).
