“…2 Studies investigating the prevalence of HPV in sex workers reported that types 16 and 18 were also the most common HPV genotypes. 28,33 Moreover, the study by Li et al revealed a similar distribution of HPV genotypes. 27 Although, prostitutes are routinely examined for HIV and other STIs in centers located in big cities, the existence and types of HPV have not been previously analyzed in Turkey.…”

“…[22][23][24][25] Another study that investigated HPV DNA by PCR reported a rate of 43.8% among female sex workers in Bulgaria, whereas it was 38.9% in China and 66.8% in Peru. [26][27][28] Previous studies from Turkey suggested an HPV DNA positivity rate between 8.7% and 21.6 %. [29][30][31] The rate in our study was higher than the average rate in Turkey, which may be attributed to the uniform compositon of the study group including only prostitutes.…”

A AB BS ST TR RA AC CT T OOb bj je ec ct ti iv ve e: : The human papilloma virus (HPV) causes various infectious clinical pictures and anogenital cancers, and it is recognized as the primary etiological agent of cervical cancer worldwide. In this study, we aimed to demonstrate the presence of HPV in prostitutes and to identify its genotypes in cervical specimens. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : This study included 137 commercial sex workers from Ankara brothels who were referred to the Ankara Municipality Hospital, Department of Venereal Diseases from September 3-7, 2007 for routine examinations and who volunteered to participate. After obtaining informed consent from the participants, one-on-one interviews were conducted to obtain sociodemographic data. Cervical specimens were collected from each subject in order to investigate HPV genotypes by DNA extraction. R Re es su ul lt ts s: : The tests for HPV DNA were positive in 53 specimens following the extraction of DNA from swab specimens collected from the prostitutes. Seven cases had genotypes associated with the low-risk cancer group, one had genotypes affiliated with the undetermined risk group, and 38 had genotypes related to the high-risk group. In addition, genotypes associated with more than one risk group were detected in seven other study participants. Four subjects had genotypes related to both the undetermined indefinite and high-risk groups, two had genotypes connected with the low and high-risk groups, and one had genotypes from all three risk groups. Eighty-four participants tested negative for HPV DNA. C Co on nc cl lu us si io on n: : Women working in brothels are at risk for venereal diseases. This should be considered to protect both their own health and public health. It is noteworthy that the genotypes of HPV identified in the prostitutes were predominately of the high-risk cancerous type. Therefore, information regarding HPV should be distributed to women working in the sex industry, and preventive measures should be implemented to protect them from acquiring HPV.

Background: Female sex workers (FSWs) are amongst the most susceptible groups to acquire human papillomavirus (HPV) infection and consequently, to develop cervical intraepithelial neoplasia and cervical cancer. This is the first systematic review and meta-analysis to provide estimates of the pooled prevalence of HPV infection and distribution of HPV types among FSWs across the world. Methods: Five computerized databases were searched for relevant studies published since the inception date of databases to September 2019. The pooled HPV prevalence was calculated by the random effect model described by DerSimonian-Laird. Subgroup analysis was performed to identify the probable sources of heterogeneity. The meta-analysis was performed using the “Metaprop” function in the R package Meta. Results: Sixty-six studies involving 22938 FSWs from 34 countries were included in this meta-analysis, and the pooled HPV prevalence was 41.97% (95% confidence interval (CI): 37.99%-46.05%). HPV-16 (10.42%, 95% CI: 8.61%–12.55%), HPV-52 (7.76%, 95% CI: 5.75%–10.39%), and HPV-53 (6.09%, 95% CI: 4.55%–8.12%) were the most common high-risk HPV types identified among FSWs. The polled estimated prevalence of HPV infection among FSWs before and after 2010 were slightly different, 43.64% (95% CI: 36.12%-51.46%) and 41.01% (95% CI: 36.35%-45.83%), respectively. Conclusion: Due to the high prevalence of HPV infection, particularly with high-risk types, FSWs have a great susceptibility to the development of cervical and vaginal cancers. Furthermore, they can transmit their infection to their clients, which may result in a high prevalence of HPV and incidence of HPV-associated malignancies among the general population.

“…Female sex workers (FSW) are at increased risk of acquiring high-risk type HPV infection compared to the general population [9,10], and when proper screening and treatment protocols are not present, are at additional risk for developing cervical cancer. In Lima, Peru, where sex work is permitted, registered FSW receive regular screening for sexually transmitted infections (STI) at designated health clinics such as the Centro de Salud “Alberto Barton” del Callao (Alberto Barton Health Center of Callao).…”

“…In Lima, Peru, where sex work is permitted, registered FSW receive regular screening for sexually transmitted infections (STI) at designated health clinics such as the Centro de Salud “Alberto Barton” del Callao (Alberto Barton Health Center of Callao). Studies have demonstrated a prevalence of cervical HPV among FSW in Lima of 50.6–66.8%, including high-risk types in 35.6–42.0%, thus highlighting the need for an intervention to ensure that women with high-risk HPV infection receive appropriate treatment to prevent progression to cervical cancer [9, 10]. …”

Barriers to Follow-Up for Abnormal Papanicolaou Smears among Female Sex Workers in Lima, Peru

et al. 2017

View full text Add to dashboard Cite

BackgroundCervical cancer is the most prevalent cancer among Peruvian women. Female sex workers (FSW) in Peru are at elevated risk for HPV infection, and receive annual Papanicolaou screening. The objective of this study was to identify barriers to follow-up for abnormal Pap smears among FSW in Peru.Methods97 FSW attending the Alberto Barton Health Center in Lima were surveyed regarding their STI screening history. 17 women with a history of an abnormal Pap smear were interviewed about their experiences regarding follow-up care.ResultsOf the 27 HPV-positive women, only 8 (30%) received follow-up treatment. Of the 19 women who did not receive follow-up, 7 (37%) had not been informed of their abnormal result. Qualitative interviews revealed that the major barrier to follow-up was lack of knowledge about HPV and potential health consequences of an abnormal Pap smear.ConclusionHPV infection is highly prevalent in Peruvian FSW, yet only 30% of FSW with abnormal Pap smears receive follow-up care. The predominant barriers to follow-up were lack of standardization in recording and communicating results and insufficient FSW knowledge regarding health consequences of HPV infection. Standardization of record-keeping and distribution of educational pamphlets have been implemented to improve follow-up for HPV.
