Oral manifestations of HIV infection and their correlation with CD4 count

Human Immunodeficiency Virus (HIV)-related oral lesions can be used as markers of the immune status. The present cross-sectional study was conducted to identify the oral manifestations in HIV-infected individuals and their association with reduced Cluster of Differentiation 4 (CD4) count. The study population included known HIV-positive patients. A detailed case history of 399 HIV-positive patients was obtained and general examination was carried out. Diagnosis of oral lesions was done based on presumptive criteria of EEC Clearinghouse, 1993. The CD4 count was determined in 369 patients and correlated with oral manifestations. The prevalence of oral lesions was found to be 76.70% (n = 306). Oral candidiasis (157 (39.3%)) was the most common oral lesion associated with HIV infection. Amongst various forms of oral candidiasis, erythematous candidiasis (122 (39.3%)) outnumbered the other forms. The mean CD4 count of patients with oral lesions (207 cells/mm3) was less than in patients without oral lesions (291 cells/mm3) (P = 0.002). Oral candidiasis was found to be significantly correlated to a reduced CD4 cell count below 200 cells/mm3 (P = 0.000; Odds ratio = 3.1; 95% Confidence interval 1.9-4.9) with good sensitivity, best specificity and positive predictive value. Oral manifestations may be used as an alternative to CD4 count at field-based settings to diagnose the immune compromised status of HIV-infected individuals. (J Oral Sci 53, 203-211, 2011)
