Objectives To compare pre and post-ART attrition between youth (15–24 years) and other patients in HIV care, and to investigate factors associated with attrition among youth. Design Cohort study utilizing routinely collected patient-level data from 160 HIV clinics in Kenya, Mozambique, Tanzania, and Rwanda. Methods Patients at least 10 years of age enrolling in HIV care between 01/05 and 09/10 were included. Attrition (loss to follow-up or death 1 year after enrollment or ART initiation) was compared between youth and other patients using multivariate competing risk (pre-ART) and traditional (post-ART) Cox proportional hazards methods accounting for within-clinic correlation. Among youth, patient-level and clinic-level factors associated with attrition were similarly assessed. Results A total of 312 335 patients at least 10 years of age enrolled in HIV care; 147 936(47%) initiated ART, 17% enrolling in care and 10% initiating ART were youth. Attrition before and after ART initiation was substantially higher among youth compared with other age groups. Among youth, nonpregnant women experienced lower pre-ART attrition than men [sub-division hazard ratio=0.90, 95% confidence interval (CI): 0.86–0.94], while both pregnant [adjusted hazard ratio (AHR) = 0.85, 95% CI: 0.74–0.97] and nonpregnant (AHR = 0.79, 95% CI: 0.73–0.86) female youth experienced lower post-ART attrition than men. Youth attending clinics providing sexual and reproductive health services including condoms (AHR = 0.47, 95% CI: 0.32–0.70) and clinics offering adolescent support groups (AHR = 0.73, 95% CI: 0.52–1.0) experienced significantly lower attrition after ART initiation. Conclusion Youth experienced substantially higher attrition before and after ART initiation compared with younger adolescents and older adults. Adolescent-friendly services were associated with reduced attrition among youth, particularly after ART initiation.

We conducted an implementation science study of a community-based ART distribution program for HIV-positive female sex workers (FSW) whereby clients received ART services through community-based mobile and home-based platforms. We compared 6-month treatment-related outcomes in the community-based ART arm (N = 256) to the standard facility-based ART delivery arm (N = 253). Those in the intervention arm were more likely to have initiated ART (100.0% vs. 71.5%; p = 0.04), be currently taking ART at the 6-month visit (100.0% vs. 95.0%; p < 0.01), and less likely to have stopped taking ART for more than 30 days continuously (0.9% vs. 5.7%; p = 0.008) or feel high levels of internalized stigma (26.6% vs. 39.9%; p = 0.001). In the adjusted regression model, internalized stigma (adjusted OR [aOR]: 0.5; 95% CI 0.28-0.83) and receiving community-based ART (aOR: 208.6; 95% CI 12.5-3479.0) were significantly associated with ART initiation. Community-based ART distribution model can improve linkage to and adherence to ART over standard facility-based ART programs for FSWs.

BackgroundHIV testing and counselling (HTC) is an essential component for HIV prevention and a critical entry point into the HIV continuum of care and treatment. Despite the importance of HTC for HIV control, access to HTC services among female sex workers (FSWs) in sub-Saharan Africa (SSA) remains suboptimal and little is known about factors influencing FSWs’ access to HTC. Guided by the client-centred conceptual framework, we conducted a systematic review to understand the facilitators and barriers influencing FSWs in SSA to access HTC services.MethodsA systematic search was conducted in MEDLINE, POPLINE and Web of Science databases for literature published between January 2000 and July 2017. References of relevant articles were also searched. We included primary studies of any design, conducted in SSA and published in the English language. Studies conducted in multi-sites inclusive of SSA were included only if data from sites in SSA were separately analysed and reported.Similarly, studies that included other subpopulations were only eligible if a separate analysis was done for FSWs. This review excluded papers published as systematic reviews, editorial comments and mathematical modelling. The protocol for this review is registered in the Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42017062203.ResultsThis review shows that factors related to approachability, acceptability, availability, affordability and appropriateness of the services are crucial in influencing access to HTC services among FSWs in SSA. These factors were mediated by individual attributes such as HIV risk perceptions, awareness of the availability of HTC, and perceptions of the importance and quality of HTC services. The decision to utilise HTC was predominantly hampered by discriminatory social norms such as HIV stigma and criminalisation of sex work.ConclusionsFSWs’ access to HTC is facilitated by multiple factors, including individual awareness of the availability of HTC services, and perceived quality of HTC especially with regard to assured confidentiality. Concerns about HIV stigma and fear about discrimination due to community intolerance of sex work acted as major barriers for FSWs to seek HTC services from the facilities offering health services to the general population.Electronic supplementary materialThe online version of this article (10.1186/s12889-018-6362-0) contains supplementary material, which is available to authorized users.

In Tanzania, HIV infection remains much higher among female sex workers (FSWs) than among other adult women. In addition to HIV, sexually transmitted infections (STIs) and pregnancy prevention are major concerns for FSWs in Tanzania. This study used a programmatic surveillance approach to examine protection against STIs/HIV and unintended pregnancy (dual method use) among FSWs in an outreach-based HIV prevention, care, and treatment program in Tanzania. 119,728 FSWs made a first visit to services served by the Sauti Project from January 2016 to September 2017. Of these 79,774 were current contraceptive users-of those, 4548 (5.7%) took a contraceptive as well as condoms, the study measure of dual family planning (FP) method use. Ninety-one percent (n = 4139) of FSWs taking dual FP methods were provided with an injectable in addition to condoms. Dual method use was lower in this study than in research studies in the region, highlighting potential differences between findings from research studies and evidence from a routine service provision setting. Self-reported consistent condom use among FSWs was 16.1%. The findings call for further research and programs to address FSW agency to increase dual protection against STIs/HIV and unintended pregnancy.

To protect HIV-infected patients and health care workers, there is an urgent need to scale up IC practices at HIV care and treatment sites, particularly at sites without anti-tuberculosis treatment services.

We have conducted a longitudinal study on factors associated with candidal vaginal colonization, a precursor of vaginitis, in a cohort of HIV-infected women in Italy. All consecutive women attending a single, tertiary care clinical site were offered free screening for sexually transmitted infections and genital disorders every 6-12 months. Candidal vaginal colonization was defined as a positive culture for Candida spp. in an asymptomatic woman. From January 1998 to July 2002 we analysed 214 women. The baseline prevalence of candidal vaginal colonization was 16.8%. In the logistic regression analysis, the time since HIV infection > or =36 months (odds ratio [OR] = 0.18, 95% confidence interval [CI] 0.016-0.53, P = 0.002) and a plasma viral load > or =10,000 copies/mL (OR = 3.9, 95% CI 1.03-14.9, P = 0.045) were independently associated with candidal colonization. Among 130 women who were followed for a mean period of 24 months, the incidence of vaginal colonization was 10.7/100 women-years. In the Cox regression analysis, a CD4(+) T-lymphocytes count <100 cells/microL during the follow-up was associated with an increased risk of candidal vaginal colonization (OR = 4.45, C.I. = 1.20-16.81, P = 0.03). Risk of candidal vaginal colonization episodes in HIV-infected women significantly increase when CD4(+) T-lymphocytes are less than 100.

In a multicenter, prospective, randomized, open-label study of isoniazid-preventive therapy (IPT) for latent tuberculosis infection, illegal immigrants from countries where tuberculosis is highly endemic were enrolled at two clinical sites in Northern Italy. Of 208 eligible subjects, 82 received supervised IPT at a dose of 900 mg twice weekly for 6 mo (Regimen A), 73 received unsupervised IPT 900 mg twice weekly for 6 mo (Regimen B), and 53 received unsupervised IPT 300 mg daily for 6 mo (Regimen C). Supervised IPT was delivered at either one tuberculosis clinic or one migrant clinic. The probability of completing a 26-wk regimen was 7, 26, and 41% in Regimens A, B, and C, respectively (p < 0.005, Log- rank test calculated using Kaplan-Meier plots). The mean time to dropout was 3. 8, 6, and 6.2 wk in Regimens A, B, and C, respectively (p = 0.003 for regimen A versus either Regimens B or C). Treatment was stopped in five subjects (2.4%) because of adverse events. The rate of completion of preventive therapy for latent tuberculosis infection among illegal immigrants was low. Supervised, clinic-based administration of IPT significantly reduced adherence. Alternative strategies to implement preventive therapy in illegal immigrants are clearly required.
