RESUMO

BACKGROUND: Chronic hepatitis B virus (HBV) infection is the predominant cause of hepatocellular carcinoma in west Africa, yet data on the incidence of HBV-related hepatocellular carcinoma remain scarce. We aimed to describe the uptake and early outcomes of systematic ultrasound-based hepatocellular carcinoma screening in SEN-B, which is a prospective HBV cohort in Senegal. METHODS: In this prospective cohort study, we included treatment-naive, HBsAg-positive individuals who were referred to the two infectious diseases clinics (the Department of Tropical and Infectious Diseases and Ambulatory Treatment Center) at Fann University Hospital of Dakar, Senegal, between Oct 1, 2019, and Oct 31, 2022. All participants resided within the Dakar region. Participants underwent abdominal ultrasound, transient elastography, and clinical and virological assessments at inclusion and every 6 months. Liver lesions at least 1 cm in diameter on ultrasound were assessed using four-phase CT, MRI, or liver biopsy. Adherence to hepatocellular carcinoma surveillance was measured using the proportion of time covered, calculated by dividing the cumulative months covered by abdominal ultrasound examinations by the overall follow-up time, defined as the number of months from the date of cohort entry until the last recorded visit, hepatocellular carcinoma diagnosis, or death. Optimal adherence was defined as a proportion of time covered of 100%. FINDINGS: Overall, 755 (99·6%) of 758 participants had at least one abdominal ultrasound performed. The median age of the enrolled participants was 31 years (IQR 25-39), 355 (47·0%) of 755 participants were women, and 82 (10·9%) had a family history of hepatocellular carcinoma. 15 (2·0%) of 755 individuals were HBeAg positive, 206 (27·3%) of 755 individuals had HBV DNA of more than 2000 IU/mL, and 27 (3·6%) of 755 had elastography-defined liver cirrhosis. Of ten (1·3%) participants with a focal lesion at least 1 cm at initial assessment, CT or MRI ruled out hepatocellular carcinoma in nine, whereas imaging and subsequent liver biopsy confirmed one patient with hepatocellular carcinoma. Two further patients with hepatocellular carcinoma were diagnosed at study presentation due to the presence of portal thrombosis on ultrasound. Excluding the three participants with hepatocellular carcinoma identified at baseline, 752 participants were eligible for screening every 6 months. Median follow-up time was 12 months (IQR 6-18) and the median number of ultrasounds per patient was 3 (2-4). During 809·5 person-years of follow-up, one incident hepatocellular carcinoma was reported, resulting in an incidence rate of 1·24 cases per 1000 person-years (95% CI 0·18-8·80). Overall, 702 (93·0%) of 755 participants showed optimal hepatocellular carcinoma surveillance, but this proportion decreased to 77·8% (42 of 54 participants) after 24 months. INTERPRETATION: Hepatocellular carcinoma screening is feasible in HBV research cohorts in west Africa, but its longer-term acceptability needs to be evaluated. Long-term hepatocellular carcinoma incidence data are crucial for shaping tailored screening recommendations.

RESUMO

BACKGROUND: Of women with cervical cancer (CC) and HIV, 85% live in sub-Saharan Africa, where 21% of all CC cases are attributable to HIV infection. We aimed to generate internationally acceptable facility-based indicators to monitor and guide scale up of CC prevention and care services offered on-site or off-site by HIV clinics. METHODS: We reviewed the literature and extracted relevant indicators, grouping them into domains along the CC control continuum. From February 2021 to March 2022, we conducted a three-round, online Delphi process to reach consensus on indicators. We invited 106 experts to participate. Through an anonymous, iterative process, participants adapted the indicators to their context (round 1), then rated them for 5 criteria on a 5-point Likert-type scale (rounds 2 and 3) and then ranked their importance (round 3). RESULTS: We reviewed 39 policies from 21 African countries and 7 from international organizations; 72 experts from 15 sub-Saharan Africa countries or international organizations participated in our Delphi process. Response rates were 34% in round 1, 40% in round 2, and 44% in round 3. Experts reached consensus for 17 indicators in the following domains: primary prevention (human papillomavirus prevention, n = 2), secondary prevention (screening, triage, treatment of precancerous lesions, n = 11), tertiary prevention (CC diagnosis and care, n = 2), and long-term impact of the program and linkage to HIV service (n = 2). CONCLUSION: We recommend that HIV clinics that offer CC control services in sub-Saharan Africa implement the 17 indicators stepwise and adapt them to context to improve monitoring along the CC control cascade.

RESUMO

As human papillomavirus (HPV) immunisation and HPV-based cervical cancer (CC) screening programmes expand across sub-Saharan Africa, we investigated the potential impact of human immunodeficiency virus (HIV) status on high-risk (HR)-HPV distribution among women with CC in Côte d'Ivoire. From July 2018 to June 2020, paraffin-embedded CC specimens diagnosed in Abidjan, Côte d'Ivoire were systematically collected and tested for HR-HPV DNA. Type-specific HR-HPV prevalence was compared according to HIV status. Of the 170 CC specimens analysed (median age 52 years, interquartile range: [43.0-60.0]), 43 (25.3%) were from women living with HIV (WLHIV) with a median CD4 count of 526 [373-833] cells/mm3 and 86% were on antiretroviral therapy (ART). The overall HR-HPV prevalence was 89.4% [95% CI: 84.7-94.1]. All were single HR-HPV infections with no differences according to HIV status (P = .8). Among HR-HPV-positive CC specimens, the most prevalent HR-HPV types were HPV16 (57.2%), HPV18 (19.7%), HPV45 (8.6%) and HPV35 (4.6%), with no significant differences according to HIV status. Altogether, infection with HPV16/18 accounted for 71.1% [95% CI: 55.9-86.2] of CC cases in WLHIV vs 78.9% [95% CI: 71.3-86.5] in women without HIV (P = .3). The study confirms the major role of HPV16/18 in CC in Côte d'Ivoire and should support a regional scale-up of HPV16/18 vaccination programmes regardless of HIV status. However, vaccines targeting additional HR-HPV types, including HPV45 and HPV35, could further decrease future CC incidence in Côte d'Ivoire, both for WLHIV and women without HIV.

RESUMO

An estimated 38 million people live with human immunodeficiency virus (HIV) worldwide and are at excess risk for multiple cancer types. Elevated cancer risks in people living with HIV (PLWH) are driven primarily by increased exposure to carcinogens, most notably oncogenic viruses acquired through shared transmission routes, plus acceleration of viral carcinogenesis by HIV-related immunosuppression. In the era of widespread antiretroviral therapy (ART), life expectancy of PLWH has increased, with cancer now a leading cause of co-morbidity and death. Furthermore, the types of cancers occurring among PLWH are shifting over time and vary in their relative burden in different parts of the world. In this context, the International Agency for Research on Cancer (IARC) and the US National Cancer Institute (NCI) convened a meeting in September 2022 of multinational and multidisciplinary experts to focus on cancer in PLWH. This report summarizes the proceedings, including a review of the state of the science of cancer descriptive epidemiology, etiology, molecular tumor characterization, primary and secondary prevention, treatment disparities and survival in PLWH around the world. A consensus of key research priorities and recommendations in these domains is also presented.

RESUMO

OBJECTIVE: To assess the impact of HIV on access to invasive cervical cancer (ICC) care and overall survival (OS) in a time of universal access to antiretroviral therapy (ART). METHODS: A cohort of women prospectively diagnosed with ICC was consecutively recruited from 2018 to 2020 in public/private cancer centers in Côte d'Ivoire. Follow-up data were collected through facility- and phone-based approaches. Logistic and Cox regression models allowed analysis of factors associated with access to cancer care and OS, respectively. RESULTS: Overall, 294 women with ICC aged 50 years (interquartile range [IQR] 43-60) were enrolled, including 21.4% of women living with HIV (WLHIV), 87% being on ART. An advanced ICC clinical stage (III-IV) was less frequent in WLHIV (63.5% vs. 77.1% in HIV-uninfected women; P = 0.029). Cancer care was initiated in 124 (42.2%) women (54.0% in WLHIV; 39.0% in HIV-uninfected; P = 0.030). Factors independently associated with access to cancer care were International Federation of Gynecology and Obstetrics (FIGO) stage I-II (adjusted odds ratio [aOR] 3.58, 95% CI 2.01-6.38) and no treatment by traditional healers prior to ICC diagnosis (aOR 3.69, 95% CI 1.96-6.96). The 2-year OS was 37.9% (95% CI 30.0-47.9). HIV status was not predictive of mortality (adjusted hazard ratio [aHR] 0.98, 95% CI 0.60-1.69). An advanced clinical stage was the only measured predictor of death (aHR 1.59, 95% CI 1.02-2.47). CONCLUSION: In a time of universal access to ART, HIV infection was not associated with OS among women with ICC in Côte d'Ivoire. Higher access to cancer care in WLHIV might be mediated by enhanced access to ICC screening services, supporting the need to expand these services to other types of healthcare facilities.

RESUMO

BACKGROUND: Cervical cancer, a major public health problem in many developing countries, is usually associated with a poor survival related to an advanced disease at diagnosis. In Côte d'Ivoire and other developing countries with high cervical cancer prevalence, little is known about factors associated with advanced cervical cancer stages in a context of limited access to screening services. METHODS: From May to July 2019, we conducted a cross-sectional study using a mixed, quantitative and qualitative method. Information on socio-demographic and history of the disease was extracted from a rapid case ascertainement study performed by the cancer registry of Côte d'Ivoire that enrolled all women diagnosed with cervical cancer between July 2018 and June 2019. In-depth semi-structured interviews were conducted among a subset of these women (12 women) and six healthcare providers to further capture barriers to early cervical cancer diagnosis. Factors associated with an advanced stage III, IV (according to FIGO classification) were estimated by a logistic regression model. Qualitative data were analyzed using a thematic analysis technique guided by the treatment pathway model and triangulated with quantitative data. RESULTS: In total, 95 women with cervical cancer [median age = 51 (IQR 42-59)] years, were included. Among them, 18.9% were living with HIV and only 9.5% were covered by a health insurance. The majority (71.5%) were diagnosed with advanced cervical cancer. Being HIV-uninfected (aOR = 5.4; [1.6-17.8], p = 0.006) and being uninsured (aOR = 13.1; [2.0-85.5], p = 0.007) were independently associated with advanced cervical cancer in multivariable analysis. Qualitative data raised additional factors potentially related to advanced cervical cancer stages at diagnosis, including the lack of patient information on cervical cancer by healthcare providers and inadequate national awareness and screening campaigns. CONCLUSION: In a context of challenges in access to systematic cervical cancer screening in Côte d'Ivoire, access to health insurance or integrated healthcare program appear to be key determinants of early diagnosis of cervical cancer.

RESUMO

BACKGROUND: Treat-All guidelines recommend initiation of antiretroviral therapy (ART) for all people with HIV (PWH) on the day of diagnosis when possible, yet uncertainty exists about the impact of same-day ART initiation on subsequent care engagement. We examined the association of same-day ART initiation with loss to follow-up and viral suppression among patients in 11 sub-Saharan African countries. METHODS: We included ART-naive adult PWH from sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium who enrolled in care after Treat-All implementation and prior to January 2019. We used multivariable Cox regression to estimate the association between same-day ART initiation and loss to follow-up and Poisson regression to estimate the association between same-day ART initiation and 6-month viral suppression. RESULTS: Among 29 017 patients from 63 sites, 18 584 (64.0%) initiated ART on the day of enrollment. Same-day ART initiation was less likely among those with advanced HIV disease versus early-stage disease. Loss to follow-up was significantly lower among those initiating ART ≥1 day of enrollment, compared with same-day ART initiators (20.6% vs 27.7%; adjusted hazard ratio: .66; 95% CI .57-.76). No difference in viral suppression was observed by time to ART initiation (adjusted rate ratio: 1.00; 95% CI: .98-1.02). CONCLUSIONS: Patients initiating ART on the day of enrollment were more frequently lost to follow-up than those initiating later but were equally likely to be virally suppressed. Our findings support recent World Health Organization recommendations for providing tailored counseling and support to patients who accept an offer of same-day ART.

RESUMO

HIV substantially worsens human papillomavirus (HPV) carcinogenicity and contributes to an important population excess of cervical cancer, particularly in sub-Saharan Africa (SSA). We estimated HIV- and age-stratified cervical cancer burden at a country, regional and global level in 2020. Proportions of cervical cancer (a) diagnosed in women living with HIV (WLHIV), and (b) attributable to HIV, were calculated using age-specific estimates of HIV prevalence (UNAIDS) and relative risk. These proportions were validated against empirical data and applied to age-specific cervical cancer incidence (GLOBOCAN 2020). HIV was most important in SSA, where 24.9% of cervical cancers were diagnosed in WLHIV, and 20.4% were attributable to HIV (vs 1.3% and 1.1%, respectively, in the rest of the world). In all world regions, contribution of HIV to cervical cancer was far higher in younger women (as seen also in empirical series). For example, in Southern Africa, where more than half of cervical cancers were diagnosed in WLHIV, the HIV-attributable fraction decreased from 86% in women ≤34 years to only 12% in women ≥55 years. The absolute burden of HIV-attributable cervical cancer (approximately 28 000 cases globally) also shifted toward younger women: in Southern Africa, 63% of 5341 HIV-attributable cervical cancer occurred in women <45 years old, compared to only 17% of 6901 non-HIV-attributable cervical cancer. Improved quantification of cervical cancer burden by age and HIV status can inform cervical cancer prevention efforts in SSA, including prediction of the impact of WLHIV-targeted vs general population approaches to cervical screening, and impact of HIV prevention.

RESUMO

PURPOSE OF REVIEW: The purpose of our review was to summarize current recommendations on testing strategies, antiviral therapy eligibility and monitoring, and prevention of mother-to-child transmission of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, and to highlight major research gaps in low and middle-income countries (LMIC), with a particular focus on sub-Saharan Africa (SSA). RECENT FINDINGS: While data on the prevalence of HBV and HCV infections in LMIC are increasing, current knowledge on liver-related complications as well as on treatment outcomes remains limited. Furthermore, very little information is available on the feasibility and cost-effectiveness of large-scale testing and management strategies in high-prevalence settings. The availability of policy-relevant data is particularly scarce in SSA, which accounts for a significant part of the global burden of chronic viral hepatitis. SUMMARY: Current recommendations on the management and monitoring of chronic viral hepatitis rely mainly on data from high-income settings. The global elimination of viral hepatitis will only be achieved if prevention, testing, and treatment strategies tailored to specific LMIC are implemented. In order to inform scalable and cost-effective interventions, dedicated research initiatives have to be undertaken. Future studies will have to include the evaluation of innovative testing strategies, the validation of simplified methods to diagnose liver cirrhosis and hepatocellular carcinoma, and the monitoring of long-term treatment outcomes and toxicity. In addition, national plans to achieve the elimination of HBV mother-to-child transmission are urgently needed, including effective ways to test pregnant women, treat those who are eligible, and ensure birth dose vaccination is given to all newborns.

RESUMO

BACKGROUNDS: Cervical cancer (CC) incidence remains unacceptably high in Côte d'Ivoire. In an effort to prevent this malignant condition, a national CC screening program has been scaled up in the country. This study aimed at assessing CC screening uptake and its associated factors in Abidjan in 2018. METHODS: A cross-sectional survey was conducted from July to September 2018 in the main healthcare facilities of three randomly selected out of the eight health districts of Abidjan. During the study period, a standardized questionnaire was administrated by research assistants to all women aged 25 to 55 years old, attending the three participating facilities. Demographics, knowledge on CC, personal history of CC screening and reasons for not attending CC screening were collected. A logistic regression model was computed to document factors associated with reported CC screening uptake. RESULTS: A total of 1158 women with a median age of 32 years (IQR [27-36]), including 364 (31.4%) with no formal education were included. Of those participants, 786 (67.9%) had ever heard about CC. CC screening uptake at least once was reported by 7.5% [95% CI: 6.0-9.0] participants. In multivariable analysis, being ≥45 years (aOR: 6.2 [2.3-17.2]), having a university level (aOR: 2.8 [1.2-6.6]) (versus non formal education) and access to mass campaign information (aOR: 18.2 [8.5-39.1]) were associated with a reported CC screening uptake. The main reported barriers to CC screening were unawareness towards CC screening (75.5%), negligence (20.5%), fear of CC detection (3.9%) and fear of additional costs (3.3%). CONCLUSION: CC screening uptake remains low despite current initiatives to support awareness and prevention in Abidjan. Awareness campaigns need to be massively increased with the adjunction of tailored messages based on the level of women's education to enhance the CC screening coverage and reach the WHO goal of CC elimination by 2030.

RESUMO

Non-Hodgkin lymphomas (NHL) are underestimated causes of cancer in West Africa where chronic viral hepatitis and HIV are endemic. While the association with HIV infection has already been characterized, limited information is available on the association between chronic viral hepatitis and NHL in sub-Saharan Africa. A case-control study was conducted in referral hospitals of Abidjan (Cote d'Ivoire) and Dakar (Senegal). Cases of NHL were matched with controls on age, gender and participating site. The diagnosis of NHL relied on local pathological examination completed with immunohistochemistry. HIV, HBV and HCV serology tests were systematically performed. A conditional logistic regression model estimated the associations by the Odds Ratio (OR) with their 95% confidence interval (CI). A total of 117 NHL cases (Abidjan n = 97, Dakar n = 20) and their 234 matched controls were enrolled. Cases were predominantly men (68.4%) and had a median age of 50 years (IQR 37-57). While Diffuse Large B-cell lymphoma were the most reported morphological type (n = 35) among mature B-cell NHL, the proportion mature T-cell NHL (30%) was high. The prevalence figures of HBV, HCV and HIV infection were 12.8%, 7.7% and 14.5%, respectively among cases of NHL. In multivariate analysis, HBV, HCV and HIV were independently associated with NHL with OR of 2.23 (CI 1.05-4.75), 4.82 (CI 1.52-15.29) and 3.32 (CI 1.54-7.16), respectively. Chronic viral hepatitis B and C were significantly associated with NHL in West Africa. Timely preventive measures against HBV infection and access to curative anti-HCV treatment might prevent a significant number of NHL.

RESUMO

PURPOSE: Major improvements have occurred in access to invasive cervical cancer (ICC) screening in HIV-infected women over the past decade in sub-Saharan Africa. However, there is limited information on changes in the burden of HIV-related ICC at a population level. Our objective was to compare HIV-related ICC over a decade and document factors associated with HIV infection in women with ICC in Côte d'Ivoire. METHODS: A repeated cross-sectional study was conducted in referral hospitals of Abidjan, Côte d'Ivoire, through the 2009-2011 and 2018-2020 periods. Women diagnosed with ICC were systematically tested for HIV. Demographics, ICC risk factors, cancer stage (International Federation of Gynecology and Obstetrics), and HIV characteristics were collected through questionnaires. Characteristics of HIV-related ICC were compared between the periods, and factors associated with HIV in women diagnosed with ICC in 2018-2020 were documented through a multivariable logistic model. RESULTS: During the 2009-2011 and 2018-2020 periods, 147 and 297 women with ICC were diagnosed with estimated HIV prevalence of 24.5% and 21.9% (P = .53), respectively. In HIV-infected women, access to antiretroviral treatment increased from 2.8% to 73.8% (P < 10-4) and median CD4 cell count from 285 (IQR, 250-441) to 492 (IQR, 377-833) cells/mm3 (P = .03). In women diagnosed with ICC during the 2018-2020 period, HIV infection was associated with a less advanced clinical stage (International Federation of Gynecology and Obstetrics I or II stage) (adjusted OR, 2.2 [95% CI, 1.1 to 4.4]) and with ICC diagnosis through a systematic screening (adjusted OR, 10.5 [95% CI, 2.5 to 45.5]). CONCLUSION: Despite a persistently high proportion of HIV-related ICC over time in Côte d'Ivoire, HIV was associated with less advanced clinical stage at ICC diagnosis. Recent improvements in ICC screening services across HIV clinics might explain this association and support their implementation across non-HIV health facilities.

RESUMO

BACKGROUND: Cervical cancer prevention strategies recommend human papilloma virus (HPV) vaccination for female adolescents prior to their sexual debut. While HIV is a major risk factor for HPV infection in women of childbearing age, its prevalence among HIV-infected adolescent female is mostly unknown. This study aimed to describe the HPV prevalence and correlates among perinatally HIV-infected adolescent females prior to HPV immunisation. METHODS: A cross-sectional survey was conducted from January to June 2016, in the four major paediatric HIV clinics of Abidjan, Côte d'Ivoire. All HIV-infected females aged 11-16 years were approached to participate in the study. A questionnaire assessing sexual behaviours and genital hygiene practices was administered to participants completed with a systematic vaginal swab collection. HPV genotyping was performed using the Anyplex II HPV28 Detection (Seegene). A logistic regression analysis was performed to identify factors associated with the presence of HPV infection. HPV immunisation was proposed free of charge to all participants. RESULTS: A total of 250 participants were included, with a median age of 13 years (IQR 11-14). Among them, 237 (94.8%) were on antiretroviral treatment with a median CD4 count of 660 (IQR 439-914) cells/mm3. The overall prevalence of at least one HPV was 3.6% (95% CI 1.6 to 6.7) and the prevalence of at least one carcinogenic HPV was 2.8% (95% CI 0.7 to 4.8). Vaginal cleansing was reported by 75 (30%) of participants, with a median age at initiation of 12 years (IQR 10-13). Sexual activity was self-reported by 12 (4.8%) participants with a median age at sexual debut of 11 years (IQR 10-14). HPV infection was associated with vaginal cleansing (adjusted OR=7.0 (95% CI 1.4 to 31.6)). CONCLUSION: The reported low prevalence of carcinogenic HPV infections supports the appropriateness of HPV immunisation in this population. The reported association between cleansing practices and HPV infection deserves further prospective longitudinal studies.

RESUMO

PURPOSE: The objectives of the International epidemiology databases to evaluate AIDS (IeDEA) are to (i) evaluate the delivery of combination antiretroviral therapy (ART) in children, adolescents and adults in sub-Saharan Africa, (ii) to describe ART regimen effectiveness, durability and tolerability, (iii) to examine HIV-related comorbidities and coinfections and (iv) to examine the pregnancy-related and HIV-related outcomes of women on ART and their infants exposed to HIV or ART in utero or via breast milk. PARTICIPANTS: IeDEA is organised in four regions (Central, East, Southern and West Africa), with 240 treatment and care sites, six data centres at African, European and US universities, and almost 1.4 million children, adolescents and adult people living with HIV (PLWHIV) enrolled. FINDINGS TO DATE: The data include socio-demographic characteristics, clinical outcomes, opportunistic events, treatment regimens, clinic visits and laboratory measurements. They have been used to analyse outcomes in PLWHIV-1 or PLWHIV-2 who initiate ART, including determinants of mortality, of switching to second-line and third-line ART, drug resistance, loss to follow-up and the immunological and virological response to different ART regimens. Programme-level estimates of mortality have been corrected for loss to follow-up. We examined the impact of coinfection with hepatitis B and C, and the epidemiology of different cancers and of (multidrug resistant) tuberculosis, renal disease and of mental illness. The adoption of 'Treat All', making ART available to all PLWHIV regardless of CD4+ cell count or clinical stage was another important research topic. FUTURE PLANS: IeDEA has formulated several research priorities for the 'Treat All' era in sub-Saharan Africa. It recently obtained funding to set up sentinel sites where additional data are prospectively collected on cardiometabolic risks factors as well as mental health and liver diseases, and is planning to create a drug resistance database.

RESUMO

OBJECTIVES: The aim of this study was to estimate alcohol and tobacco use prevalence and their correlates among female sex workers (FSW), men who have sex with men (MSM) and drug users (DU) in Togo. DESIGN, SETTING AND PARTICIPANTS: A cross-sectional bio-behavioural study was conducted among 2115 MSM, FSW and DU in 2017 using a respondent-driven sampling method, in the eight biggest towns of Togo. Selection criteria for the MSM were being male and having had oral or anal intercourse with a man in the previous 12 months; for FSW, being a female and having exchanged sex for money in the previous 12 months; and for DU, consuming heroin, cocaine or hashish for MSM, FSW and DU, respectively. All participants had to be at least 18 years old and residing in the territory for the past 3 months. RESULTS: The prevalence of alcohol consumption, hazardous/harmful consumption and binge drinking was 64.8%, 38.4% and 45.5%, respectively. Current tobacco use was reported by 30.6% of participants and HIV prevalence was estimated at 12.5%. DU were more likely to engage in binge drinking compared with other key populations (adjusted odds ratio (aOR)=2.0; 95% CI 1.4 to 2.8; p=0.001). Participants who were identified as having hazardous/harmful alcohol consumption had almost three times the odds of tobacco consumption than those with no risky consumption (aOR=2.6; 95% CI 2.0 to 3.4; p=0.001). Hazardous/harmful alcohol consumption was three times more likely among participants with severe psychological distress compared with those with no psychological distress (aOR=3.3, 95% CI 2.2 to 5.1; p=0.001). CONCLUSION: Findings from this study demonstrate the need for the integration of mental health and substance abuse reduction interventions into HIV prevention programme, particularly those geared towards key populations.

RESUMO

OBJECTIVES: Despite the increasing number of interventions aiming to integrate cervical cancer screening into HIV clinics in sub-Saharan Africa, Women living with HIV (WLHIV) still have a high risk of developing cervical cancer. The aim of this study was to estimate the coverage of cervical cancer screening and associated factors among WLHIV in Abidjan, Côte d'Ivoire. DESIGN: Cross-sectional survey conducted from May to August 2017. SETTINGS: Outpatient setting in the four highest volume urban HIV clinics of government's or non-governmental organisation's sector in Côte d'Ivoire. PARTICIPANTS: All WLHIV, aged 25-55 years, followed since at least 1 year, selected through a systematic sampling procedure. INTERVENTION: A standardised questionnaire administered to each participant by trained healthcare workers. OUTCOME: Cervical cancer screening uptake. RESULTS: A total of 1991 WLHIV were included in the study, aged in median 42 years (IQR 37-47), and a median CD4 count (last known) of 563 (378-773) cells/mm3. Among the participants, 1913 (96.1%) had ever heard about cervical cancer, 1444 (72.5%) had been offered cervical cancer screening, mainly in the HIV clinic for 1284 (88.9%), and 1188 reported a personal history of cervical cancer screening for an overall coverage of 59.7% (95% CI 57.6 to 62.0). In multivariable analysis, university level (adjusted OR (aOR) 2.1; 95% CI 1.4 to 3.1, p<0.001), being informed on cervical cancer at the HIV clinic (aOR 1.5; 95% CI 1.1 to 2.0, p=0.017), receiving information self-perceived as 'clear and understood' on cervical cancer (aOR 1.7; 95% CI 1.4 to 2.2, p<0.001), identifying HIV as a risk factor for cervical cancer (aOR 1.4; 95% CI 1.1 to 1.8, p=0.002) and being proposed cervical cancer screening in the HIV clinic (aOR 10.1; 95% CI 7.6 to 13.5, p<0.001), were associated with cervical cancer screening uptake. CONCLUSION: Initiatives to support cervical cancer screening in HIV care programmes resulted in effective access to more than half of the WLHIV in Abidjan. Efforts are still needed to provide universal access to cervical cancer screening, especially among socioeconomically disadvantaged WLHIV.

RESUMO

OBJECTIVE: To report the successes and challenges of scaling up a population-based cervical cancer (CC) screening program from HIV clinics to various healthcare facilities in Abidjan, Côte d'Ivoire. METHOD: A retrospective analysis of characteristics, outcomes, and follow-up of women attending an initial CC screening visit in Abidjan between January 2010 and December 2014. Data were collected via forms that were systematically completed during CC screening visits. Data from the 2014 population census were used to estimate screening coverage. RESULTS: Among 16 169 women attending an initial CC screening, 1616 (10.0%) had a positive VIA test. Among 848 women eligible for immediate cryotherapy, 618 (72.9%) underwent the "see-and-treat" approach. The 1-year follow-up rate after cryotherapy was 23.1% (143/618), and was higher among women with HIV (111/362, 30.7%) than among other women (32/256, 12.5%) (P=0.001). The estimated coverage of CC screening in Abidjan was 1.2% (95% confidence interval, 0.6-3.1). CONCLUSION: Despite successful expansion of CC screening from HIV clinics to other facilities, the estimated screening coverage of the targeted population remained low. Follow-up of positively screened and treated women is a major challenge, especially outside HIV clinics, and would benefit from an innovative information system proving unique identification and tracking systems.

RESUMO

BACKGROUND: Sub-Saharan Africa is a region of both high human immunodeficiency virus (HIV) and anal cancer incidence. We conducted the first national study in Togo to assess human papillomavirus (HPV), HIV, and other sexually transmitted infection (STI) prevalence among men who have sex with men (MSM). METHODS: A multicentric cross-sectional study was conducted among MSM recruited in 4 Togolese cities. Anal swabs were collected to test HPV, herpes simplex virus (HSV), and 7 STIs. RESULTS: Among the 207 MSM, HIV and high-risk HPV (hrHPV) overall prevalence were 26.1% and 44.9%, respectively. The most common hrHPV types were HPV-35 (15.0%) and HPV-16 (13.0%). Prevalence of hrHPV and multiple HPV infections were higher among HIV-infected than among HIV-uninfected MSM (85.2% vs 30.7%, P < 10-5 and 85.2% vs 28.7%, P < 10-5, respectively). Other STIs, except hepatitis B virus, were also more prevalent among HIV-infected MSM (Neisseria gonorrhoeae, P = .03; Mycoplasma genitalium, P = .04; HSV-2, P = .001; and a trend for Chlamydia trachomatis, P = .06). In multivariate analysis (adjusted odds ratio [95% confidence interval]), HIV (10.1 [4.0-25.6]), living in Lomé (2.8 [1.1-7.1]), HSV-2 excretion (26.7 [2.9-244.3]), C. trachomatis (11.7 [2.3-58.9]), and M. genitalium infection (9.6 [3.1-29.9]) were associated with increased risk of hrHPV infection. CONCLUSIONS: We report a high burden of anal STIs with an unusual hrHPV type distribution among MSM, highlighting the critical need of implementation of a national strategy regarding prevention of STIs and vaccination against HPV.
