Association of opium use and tobacco smoking with α-, β-, and γ-human papillomavirus oral infection
Menée à l'aide d'échantillons salivaires prélevés chez 242 témoins et 498 patients atteints d'un carcinome épidermoïde de la tête et du cou, cette étude analyse l'association entre la consommation de tabac ou d'opium et le risque d'infection orale par le papillomavirus humain
Head and neck squamous cell carcinomas (HNSCCs) are linked to tobacco smoking, opium use, and human papillomavirus (HPV) infection. However, little is known about the association of HPV infection with risk factors of HNSCCs, including opium and tobacco use. This cross-sectional analysis of a national multi-center case–control study in Iran included 498 HNSCC cases and 242 controls. We investigated the association of opium and tobacco use with α- (n = 21), β- (n = 46), and γ-HPV (n = 52) types in saliva samples using type-specific bead-based multiplex genotyping assays (TS-MPG). We found that α-HPV positivity was significantly associated with tobacco smoking (OR = 10.35; 95% CI = 1.15, 93; p = .03), but not with opium use (OR = 1.06; 95% CI = 0.41, 2.76; p = .89). Additionally, tobacco smoking correlated with an elevated risk of β-species 2 HPV infection (OR = 1.28; 95% CI = 1.04, 1.58; p = .020). Conversely, opium use showed a positive association with γ-species 12 HPV infection (OR = 5.67; 95% CI = 1.43, 22.44; p = .013). These findings indicate that tobacco and opium use may influence the risk of HPV infection in different ways depending on the HPV genus and species. Further studies are needed to replicate these findings in other populations.
