Distribution of High-Risk Human Papillomavirus in Self-Collected Cervicalvaginal Samples from the General Malian Population

Cervical cancer (CC) remains a real public health problem in low- and middle-income countries, where technical resources and competent personnel are insufficient. Persistent cervix infection by high-risk human papillomavirus (Hr-HPV) is the main cause of CC development. In the current study, we examined the distribution of Hr-HPV in the general healthy Malian population using cervicovaginal self- sampling. A total of 354 women were recruited, with a median age of 34 ± 11.37 years, IQR (27–43). We found that 100% of participants agreed to self-sample at the health center. For result announcement 99.2% expressed their preference to be contacted by cell phone. Furthermore, 100% of study participants showed their willingness to undergo confirmatory CC test in case of Hr-HPV test proved positive, and to receive treatment in the event of the presence of cervical lesions. The overall prevalence of Hr-HPV was 21.2% (95% CI: 17–25.8). HPV31/35/33/52/58 with 11.9% (95% CI: 8.7–15.7) and HPV39/68/56/66 with 5.9% (95% CI: 3.7–8.9) were the most common Hr-HPV subtypes. We noted that Hr-HPV genotypes were more prevalent among women under 25 years, 36.1% (N = 61). In addition, the distribution of Hr-HPV was statistically associated with age, W = 12,374, p = 0.015. Our data showed that 25.3% (N = 19) of Hr-HPV-positive women were tested positive by VIA/VILI. Among the 19 VIA/VILI-positive women, histological examination showed that 4 were CIN1, 4 were CIN2, and 2 were CIN3 grades. In addition, the median age of participants with CIN2 and CIN3 was statistically higher than the median of those with CIN1 grade, 25 years IQR (21–26.75) versus 50 years, IQR (40.25–55), W = 24, p = 0.009. In sum, end-users are very satisfied with the cervicovaginal self-sampling device for identifying HR-HPV genotypes as part of CC screening. In addition, it enables hospital practitioners to take the necessary action after triaging women according to their HR-HPV genotype.
