Prevalence of Oral Mucosal Lesions and Relation to Serum Cotinine Levels-Findings from a Cross-Sectional Study in South Africa.

ABSTRACT: Oral mucosal lesions (OML) can decrease oral health-related quality of life and some have the potential to become malignant. The aim of the present study was to report the prevalence of OML in relation to age, sex, and serum cotinine levels in a population with mixed ancestry from South Africa. This study is part of the Cape Town Vascular and Metabolic Health (VHM) study, conducted between 2014-2016. Trained dental examiners assessed the oral mucosa for the presence of OML according to WHO criteria. In total, 1976 individuals were included in the study, being 1496 females (75.7%) and 480 males (24.3%) with average age of 49.5 years (SD = 15.3). In total, 262 lesions were detected in 252 participants (overall prevalence of 13%). Males had higher prevalence than females (14% vs. 9%, p = 0.008). Participants aged 25-34 had the highest prevalence rates (21%). Participants who had cotinine ?15 ng/mL had higher prevalence of OML as compared to those with <15 ng/mL (15% vs. 5%, p < 0.001). Most common lesions were nicotine stomatitis (33%) and leukoplakia (19%). Age, male sex, and higher cotinine levels were associated with increased prevalence of OML.

Project description:ObjectiveTo estimate the prevalence, incidence and persistence of anal HPV infection and squamous intra-epithelial lesions (SILs) among men living with HIV (MLHIV), and determine their risk factors.MethodsWe enrolled MLHIV ≥18 years, who attended 6-monthly visits for 18 months. Socio-behavioural data were collected by questionnaire. Clinicians collected blood sample (CD4+ count and HIV plasma viral load), anal swabs (HPV DNA testing) and anal smears (Bethesda classification) at each visit. HPV DNA testing and classification of smears were done at enrolment and last follow-up visit (two time points). Factors associated with persistent anal HPV infection and SILs were evaluated with generalized estimating equations logistic regression and standard logistic regression respectively.ResultsMean age of 304 participants was 38 (Standard Deviation, 8) years; 25% reported >1 sexual partner in the past 3 months. Only 5% reported ever having sex with other men. Most (65%) participants were taking antiretroviral treatment (ART), with a median CD4+ count of 445 cells/μL (IQR, 328-567). Prevalence of any-HPV infection at enrolment was 39% (88/227). In total, 226 men had anal HPV DNA results at both enrolment and final visits. Persistence of any-anal HPV infection among 80 men who had infection at enrolment was 26% (21/80). Any persistent anal HPV infection was more frequent among MLHIV with low CD4+ count (<200 vs. >500 cells/μL; aOR = 6.58; 95%CI: 2.41-17.94). Prevalence of anal SILs at enrolment was 49% (118/242) while incidence of SILs among MLHIV who had no anal dysplasia at enrolment was 27% (34/124). Of the 118 men who had anal dysplasia at enrolment, 15% had regressed and 38% persisted by month 18. Persistent anal HPV infection was associated with persistent SILs (aOR = 2.95; 95%CI: 1.08-10.89). ART status or duration at enrolment were not associated with persistent anal HPV infection or persistent SILs during follow-up.ConclusionIn spite of a high prevalence of anal HPV, HIV-positive heterosexual men have a low burden of anal HPV related disease. HPV vaccine and effective ART with immunological reconstitution could reduce this burden of infection.
