Prevalence of Oral Lesions among HIV Positive Patients Attending Antiretroviral Therapy Centre in Rural Area of Western Maharashtra

Introduction: The Oral Manifestations (OM) of Human Immunodeficiency Virus (HIV) is indication of compromised immune status and disease progression. These Oral Lesions (OL) cause morbidity and affect quality of life of the patients. Aim: To evaluate the association between OM in patients with HIV infection and their level of cluster of differentiation 4 (CD4) count. Materials and Methods: The study was designed as a descriptive, cross-sectional study for a duration of two years which included a total of 565 known HIV-positive individuals visiting the regional Antiretroviral Therapy (ART) center for counseling and/or on Highly Active Antiretroviral Therapy (HAART) were selected irrespective of age and sex. The oral lesions were diagnosed using the presumptive criteria given by by the European Committee (EC) Clearinghouse, 1993. Oral and systemic manifestations were recorded and associated with CD4 counts. The data collected was subjected to statistical analysis using Statistical Package of Social Science (SPSS) 8.0 software and p-value was considered significant at a level of 0.05. Results: The male-to-female ratio was almost equal and 95.04% of the patients had reported heterosexual contact as the transmission route. The peak age of occurrence of HIV infection was during 31-40 years with the mean age of males and females 39.26 years and 34.46 years respectively. Pulmonary tuberculosis (16.11%) and herpes zoster (16.81%) were the most common systemic manifestations. The prevalence of OM reported was 86.01% and was higher in females than in males. Intraoral melanotic pigmentation (50.08%) was the most common finding, followed by periodontitis (36.46%), linear gingival erythema (14.51%), Necrotising ulcerative gingivitis (NUG) (4.42%), candidiasis (8.67%), oral ulcers, herpes zoster (5.13%), herpes simplex virus infection (1.17%) and salivary gland disease (SGD) (0.7%). There was a significant association (p=0.0110) between OL and reduced CD4 count. Conclusion: OL occur commonly in HIV infection. The decrease in CD4 count is associated with a wide range of OM. The result from this study can be used as predictive marker for oral manifestations in AIDS based on the level of immune suppression and help in improving their quality of life.
