Whelan J, Abbing-Karahagopian V, Serino L, Unemo M. Gonorrhoea: a systematic review of prevalence reporting globally. BMC Infect Dis 2021; 21:1152. [PMID: 34763670 PMCID: PMC8582208 DOI: 10.1186/s12879-021-06381-4] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Accepted: 06/09/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The World Health Organization (WHO) recommends periodic gonorrhoea prevalence assessments in the general population or proxies thereof (including pregnant women, women attending family planning clinics, military recruits, and men undergoing employment physicals for example) and in population groups at increased risk, including men-who-have-sex-with-men (MSM) and sex workers. METHOD We evaluated reported prevalence data, including estimates from proxy general population samples to reflect the WHO recommendations. We describe the outcomes from the general population country-by-country and extend previous reviews to include MSM, sex workers, and extragenital infections. RESULT AND CONCLUSION In our systematic search, 2015 titles were reviewed (January 2010-April 2019) and 174 full-text publications were included. National, population-based prevalence data were identified in only four countries (the United States of America, the United Kingdom, Peru, New Caledonia) and local population-based estimates were reported in areas within five countries (China, South Africa, Brazil, Benin, and Malawi). The remaining studies identified only reported test positivity from non-probability, proxy general population samples. Due to the diversity of the reviewed studies, detailed comparison across studies was not possible. In MSM, data were identified from 64 studies in 25 countries. Rectal infection rates were generally higher than urogenital or pharyngeal infection rates, where extragenital testing was conducted. Data on sex workers were identified from 41 studies in 23 countries; rates in female sex workers were high. Current prevalence monitoring was shown to be highly suboptimal worldwide. Serial prevalence monitoring of critical epidemiological variables, and guidelines to optimize prevalence study conduct and reporting beyond antenatal settings are recommended.

Prevalence and genotype distribution of genital human papillomavirus infection in female sex workers in the world: a systematic review and meta-analysis. BMC Public Health 2020; 20:1455. [PMID: 32977797 PMCID: PMC7519561 DOI: 10.1186/s12889-020-09570-z] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Accepted: 09/20/2020] [Indexed: 12/16/2022] Open
Abstract
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 the 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-two studies involving 21,402 FSWs from 33 countries were included in this meta-analysis, and the pooled HPV prevalence was 42.6% (95% confidence interval (CI): 38.5-46.7%). HPV-16 (10.1, 95% CI: 8.2-12.5%), HPV-52 (7.9, 95% CI: 5.9-10.7%), and HPV-53 (6.0, 95% CI: 4.4-8.1%) were the most common high-risk HPV types identified among FSWs. The pooled estimated prevalence of HPV infection among FSWs before and after 2010 were slightly different, 43.6% (95% CI: 36.1-51.4%) and 41.9% (95% CI: 37.2-46.8%), 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 the incidence of HPV-associated malignancies among the general population.

Abstract
OBJECTIVE Neisseria gonorrhoeae infection is a global, major public health problem. It is the second leading bacterial sexually transmitted infection (STI) in sub-Saharan Africa and worldwide. As study findings on the topic are inconsistent, we conducted a systematic review and meta-analysis to determine the pooled prevalence of N. gonorrhoeae infection in sub-Saharan Africa among reproductive-aged women. METHODS Published studies were systematically retrieved from PubMed, Embase, CINHAL and Science Direct. Their quality was measured using the Joanna Briggs Institute critical appraisal checklist for studies reporting prevalence data, and the score of each included study had to meet at least 4.5 out of 9 indicators of quality. RESULTS The meta-analysis of 35 studies showed that the pooled prevalence of N. gonorrhoeae infection among reproductive-aged women in sub-Saharan Africa was 3.28% (95% confidence interval 2.61%, 3.94%). CONCLUSION The prevalence of N. gonorrhoeae infection was higher than that found in other studies carried out in the region. The results suggest that greater attention should be paid to the primary prevention of N. gonorrhoeae. We recommend the implementation of STI education for reproductive-aged women and the use of specific and rapid diagnostic testing for N. gonorrhoeae infection in STI clinics. N. gonorrhoeae screening and treatment should be integrated into in- and outpatient clinics to reduce infection among reproductive-aged women.

Abstract
Chlamydia trachomatis and Neisseria gonorrhoeae constitute major public health problems among women, but the burden of infection in sub-Saharan Africa is poorly documented. We conducted a structured review of the prevalence and incidence of genital, oral and anal C. trachomatis and N. gonorrhoeae infection in women in sub-Saharan Africa. We searched Medline, EMBASE and Web of Science over a 10-year period for studies on epidemiology of genital, oral and anal chlamydial infection and gonorrhoea in women in all countries of sub-Saharan Africa. We assessed geographic and demographic differences in prevalence and incidence of infection; weighted mean prevalence estimates were calculated with a random-effect model. A total of 102 study results were included, with data available for 24/49 of sub-Saharan countries. The weighted prevalence of chlamydial infection was lower among women in community-based studies (3.9%; 95% CI: 2.9-5.1%) than for women recruited at primary healthcare facilities (6.0%; 95% CI: 4.2-8.4%, p < 0.001); the same was observed for gonorrhoea (2.2%; 95% CI: 1.2-4.0% vs. 4.2%; 95% CI: 3.2-5.6%, p < 0.001). Prevalence of Chlamydia among sex workers was 5.5% (95% CI: 4.2-7.3%) and gonorrhoea 7.6% (95% CI: 5.4-11%). Seven studies reported on incidence which varied between 0.75-28 and 2.8-17 per 100 person-years-at-risk for chlamydial infection and gonorrhoea, respectively. Only two studies reported on anal infections and one on oral infection. This overview underscores the considerable incidence and prevalence of genital C. trachomatis and N. gonorrhoeae in women in different settings in sub-Saharan Africa. Better control strategies are warranted to reduce the burden of infection and to prevent long-term complications of these infections.

Clinical characteristics of hypertrophic herpes simplex genitalis and treatment outcomes of imiquimod: a retrospective observational study. Int J Infect Dis 2015; 33:165-70. [PMID: 25660091 DOI: 10.1016/j.ijid.2015.02.002] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2014] [Revised: 01/29/2015] [Accepted: 02/02/2015] [Indexed: 10/24/2022] Open
Abstract
OBJECTIVE Atypical presentations of herpes simplex genitalis are becoming more frequent. The aim of this study was to investigate the atypical clinical manifestations and treatment of this infection. METHODS The charts of patients with herpes simplex genitalis who attended our clinics between January 2009 and December 2013 were reviewed retrospectively. RESULTS Of 294 patients, 147 (50%) were male with a mean (standard deviation, SD) age of 48.3 (16.8) years. An ulcerative lesion was the most common symptom (48.3%), followed by vesicle clusters (36.4%). The mean duration of symptoms at first visit was 6 days. Oral acyclovir was administered to 87.6% of patients. Hypertrophic manifestations were observed in 4.8% (14/294) of patients; 50% (7/294) were male, with a mean age of 44.5 (SD 9) years. All patients with hypertrophic manifestations were infected with HIV. Hypertrophic manifestations had a mean duration of onset of 53.3 days. Acyclovir was prescribed to 11 (78.6%) patients. The mean duration to cure was 40.9 days. Topical imiquimod was given in six resistant cases (42.9%) as adjunctive therapy. CONCLUSIONS Atypical manifestations of herpes simplex genitalis require careful consideration because their frequency is rising, particularly in patients with HIV infection. Although acyclovir is important in their treatment, imiquimod provides an additional benefit in resistant cases.
