Oral manifestations of HIV infection in adult patients from the province of Sancti Spiritus, Cuba.
BACKGROUND
Studies on the prevalence of HIV-related oral lesions (HIV-OL) have shown great variations among different countries. The aim of this study was to describe the prevalence of HIV-OL in adults infected with HIV in the province of Sancti Spiritus, Cuba, and to determine the factors associated with the presence of HIV-OL.


METHODS
A cross-sectional observational study was performed between November 2006 and August 2007 at the Hospital General Universitario 'Camilo Cienfuegos', Sancti Spiritus. One hundred and fifty-four HIV-infected patients were included. Patients were examined and interviewed by a periodontal specialist. Diagnosis of HIV-OL was based on clinical criteria. Demographical, clinical and laboratory data were obtained. Independent association of each factor with HIV-OL was assessed by logistic regression modelling.


RESULTS
The prevalence of HIV-OL was 40.9%. The commonest manifestation was oral hairy leucoplakia (n = 19; 12.3%); oral candidiasis (n = 17; 11%); herpes simplex virus infection (n = 11; 7.4%); and aphthous ulcer (n = 9; 5.8%). Principal factors associated with the presence of HIV-OL were CD4(+) lymphocytes <500 cells/mm(3) (OR: 2.06; 95% CI: 1.019-4.195) and smoking (OR: 2.03 CI: 1.037-3.982).


CONCLUSIONS
This study described the prevalence of HIV-OL in 154 HIV-infected patients which represent about 80% of those known to be infected in the province of Sancti Spiritus. The prevalence of HIV-OL was lower than those reported from developing countries. Oral hairy leucoplakia and oral candidiasis were the most prevalent HIV-OL. Smoking and CD4(+) cells count <500 cells/mm(3) were the two factors independently associated with the presence of HIV-OL.
