Prevalence and Subtype Distribution of High-Risk Human Papillomavirus Among Women Presenting for Cervical Cancer Screening at Karanda Mission Hospital

Prevalence of High Risk HPV amongst marginalized urban women in India and its implications on vaccination: A cross sectional study

Cervical cancer is the second most common cancer among reproductive age women in India. It is a preventable by HPV vaccination programs and effective screening but it is abysmally low at less than 2% in India.

OBJECTIVE

To find out the prevalence and distribution of high risk HPV subtypes in urban slums and its implications.

METHODS

A cross-sectional study was done to know prevalence and distribution of high risk HPV subtypes. We screened 956 women. Data was analyzed using IBM SPSS 25.

INCLUSION CRITERIA

Married women between 30-45 years of age EXCLUSION CRITERIA: Women with known cervical cancer at the time of the survey or those who had undergone hysterectomy.

RESULTS

32.47% of women were HPV positive and out these about 84.50% were positive for high risk HPV. HPV 6 and 11 were not seen in the population. After 16 and 18, 58 was the most common variant seen in our study. Currently used vaccines in India do not cover 58.

CONCLUSION

There is a need for knowing and understanding distribution of high risk HPV to have effective strategy to elimination cervical cancer from India. DNA based HPV screening is a useful method along with vaccination to prevent cervical cancer.

Anal and cervical human papillomavirus genotypes in women co-infected with human immunodeficiency virus: A systematic review

Human papillomavirus (HPV) and human immunodeficiency virus (HIV) infections are sexually transmitted. There are several HPV genotypes and clinical manifestations. Determining which genotypes circulate worldwide and/or in specific geographic areas can help with prevention programs and vaccine distribution. This systematic review aimed to investigate the most frequent anal and cervical HPV genotypes in women co-infected with HPV/HIV. The PubMed, Scientific Electronic Library Online, and Latin American and Caribbean Literature in Health Sciences databases were used to search for articles published between January 2015 and August 2021, and the included articles followed the defined selection criteria. Based on the 51 articles included, HPV16 was the most prevalent (41%) genotype, followed by HPV52 (17%) and HPV58 (14%). Based on the comparative analyses of the HIV-negative women with HPV and the HPV/HIV co-infected groups, HPV16 was frequent in both groups; HPV58, HPV31, and HPV52 were more frequent in the co-infected group; and HPV18 was more common in HIV-negative women with HPV. HPV/HIV co-infected women most frequently presented the HPV genotypes 16, 58, and 52, whereas HIV-negative women with HPV had a higher frequency of HPV16, HPV18, and HPV52 genotypes. The results indicate the importance of genotype surveillance as a strategy to improve preventive measures against HPV infection and its complications.

Cervical human papillomavirus prevalence, risk factors and outcomes in a cohort of HIV-infected women in Harare, Zimbabwe

Background

Human papillomavirus (HPV) associated invasive cervical cancer (ICC) is common in Zimbabwe, disproportionately affecting women living with HIV (WLHIV). Understanding high-risk HPV (hrHPV) infection in relation to cervical disease is important for ICC prevention amongst WLHIV.

Objectives

To describe the prevalence of cervical hrHPV, type distribution, associated risk factors and ICC screening outcomes in an urban cohort of Zimbabwean women.

Methods

In this cohort study, WLHIV were tested for hrHPV infection using the Cepheid Xpert® HPV assay and followed up for incident cervical disease. Follow-up assessments were done by visual inspection with acetic acid (VIA). Descriptive statistics and logistic regression were used to describe hrHPV burden and association between hrHPV and potential risk factors. Incidence rates (IR) and rate ratios of cervical disease by hrHPV infection status were also calculated.

Results

Amongst 321 WLHIV recruited, hrHPV prevalence was 24.9% (n = 80). Fifty-two of these women (65%) were positive for hrHPV types other than 16 or 18/45. Younger age (22–29 years), early sexual debut (13–16 years) and antiretroviral therapy (ART) regimen (second-line ART) were independently associated with hrHPV positivity. Positive VIA IR ratio between hrHPV-positive and -negative women was 12.57 (95% confidence interval [CI]: 4.14–38.19). Only women with hrHPV infection had incident cervical disease (IR: 6.41/100 person-years, (95% CI: 3.33–12.32). There were no ICC cases by the end of the 2-year follow-up.

Conclusion

There was a high prevalence of hrHPV infection other than 16 and 18/45 in this cohort. Integrating HPV testing in cervical cancer screening programmes may increase screening intervals in hrHPV-negative women, reducing costs for programmes. We recommend further research into cross protectivity of the bivalent and quadrivalent HPV vaccines against these other hrHPV types.
