RESUMO

BACKGROUND: The burden of sexually transmitted infections (STIs) has been increasing in Kenya, as is the case elsewhere in sub-Saharan Africa, while measures for control and prevention are weak. The objectives of this study were to (1) describe healthcare provider (HCP) knowledge and practices, (2) explore HCP attitudes and beliefs, (3) identify structural and environmental factors affecting STI management, and (4) seek recommendations to improve the STI program in Kenya. METHODS AND FINDINGS: Using individual in-depth interviews (IDIs), data were obtained from 87 HCPs working in 21 high-volume comprehensive HIV care centers (CCCs) in 7 of Kenya's 8 regions. Transcript coding was performed through an inductive and iterative process, and the data were analyzed using NVivo 10.0. Overall, HCPs were knowledgeable about STIs, saw STIs as a priority, reported high STI co-infection amongst people living with HIV (PLHIV), and believed STIs in PLHIV facilitate HIV transmission. Most used the syndromic approach for STI management. Condoms and counseling were available in most of the clinics. HCPs believed that having an STI increased stigma in the community, that there was STI antimicrobial drug resistance, and that STIs were not prioritized by the authorities. HCPs had positive attitudes toward managing STIs, but were uncomfortable discussing sexual issues with patients in general, and profoundly for anal sex. The main barriers to the management of STIs reported were low commitment by higher levels of management, few recent STI-focused trainings, high stigma and low community participation, and STI drug stock-outs. Solutions recommended by HCPs included formulation of new STI policies that would increase access, availability, and quality of STI services; integrated STI/HIV management; improved STI training; increased supervision; standardized reporting; and community involvement in STI prevention. The key limitations of our study were that (1) participant experience and how much of their workload was devoted to managing STIs was not considered, (2) some responses may have been subject to recall and social desirability bias, and (3) patients or clients of STI services were not interviewed, and therefore their inputs were not obtained. While considering these limitations, the number and variety of facilities sampled, the mix of staff cadres interviewed, the use of a standardized instrument, and the consistency of responses add strength to our findings. CONCLUSIONS: This study showed that HCPs understood the challenges of, and solutions for, improving the management of STIs in Kenya. Commitment by higher management, training in the management of STIs, measures for reducing stigma, and introducing new policies of STI management should be considered by health authorities in Kenya.

RESUMO

BACKGROUND: Sentinel surveillance for HIV among women attending antenatal clinics using unlinked anonymous testing is a cornerstone of HIV surveillance in sub-Saharan Africa. Increased use of routine antenatal HIV testing allows consideration of using these programmatic data rather than sentinel surveillance data for HIV surveillance. METHODS: To gauge Kenya's readiness to discontinue sentinel surveillance, we evaluated whether recommended World Health Organization standards were fulfilled by conducting data and administrative reviews of antenatal clinics that offered both routine testing and sentinel surveillance in 2010. RESULTS: The proportion of tests that were HIV-positive among women aged 15-49 years was 6.2% (95% confidence interval [CI] 4.6-7.7%] in sentinel surveillance and 6.5% (95% CI 5.1-8.0%) in routine testing. The agreement of HIV test results between sentinel surveillance and routine testing was 98.0%, but 24.1% of specimens that tested positive in sentinel surveillance were recorded as negative in routine testing. Data completeness was moderate, with HIV test results recorded for 87.8% of women who received routine testing. CONCLUSIONS: Additional preparation is required before routine antenatal HIV testing data can supplant sentinel surveillance in Kenya. As the quality of program data has markedly improved since 2010 a repeat evaluation of the use of routine antenatal HIV testing data in lieu of ANC sentinel surveillance is recommended.

RESUMO

This is the first study to identify levels of recent HIV testing and associated factors among men who have sex with men (MSM) in Mozambique. Using data from Maputo (n = 493), Beira (n = 572), and Nampula/Nacala (n = 347), collected via respondent-driven sampling in 2011, and excluding those with prior known infection, we found that 30.4 % [95 % confidence interval (CI) 25.0-36.3 %], 42.1 % (95 % CI 36.8-47.3 %) and 29.8 % (95 % CI 22.9-36.9 %), respectively, had recently tested for HIV (≤12 months), while between three and five out of 10 MSM had never tested. A range of factors was associated with recent HIV testing such as familiarity with the modes of transmission, knowledge of antiretroviral treatment for HIV, contact with peer educators and awareness of partner serostatus; yet, surprisingly recent healthcare utilization was not associated with recent testing. Findings provide evidence that structural and behavioral interventions among MSM may play an important role in increasing HIV testing.

RESUMO

The population of men who have sex with men (MSM) has been largely ignored in HIV-related policies and programming in Mozambique and there is little information about the contribution of MSM to the HIV epidemic. An integrated biological and behavioral study among MSM using respondent-driven sampling was conducted in 2011 in Maputo, Beira and Nampula/Nacala. Men who reported engaging in oral or anal sex with other men in the last 12 months answered a questionnaire and provided a blood sample for HIV testing. The prevalence of HIV was 8.2 % (Maputo, n = 496), 9.1 % (Beira, n = 584) and 3.1 % (Nampula/Nacala, n = 353). Prevalence was higher among MSM ≥ 25 vs. 18-24 years: 33.8 % vs. 2.4 % (p < 0.001), 32.1 vs. 2.8 % (p < 0.001), and 10.3 vs. 2.7 % (p < 0.06), in each city respectively. The difference in prevalence demonstrates the need to increase prevention for younger MSM at risk for HIV and ensure care and treatment for older HIV-infected MSM.

RESUMO

BACKGROUND: An estimated 260,000 children under the age of 15 years acquired HIV infection in 2012. As much as 42% of mother-to-child transmission is related to breastfeeding. Antiretroviral prophylaxis for mothers or infants has the potential to prevent mother-to-child transmission of HIV through breast milk. OBJECTIVES: To determine which antiretroviral prophylactic regimens are efficacious and safe for reducing mother-to-child transmission of HIV through breastfeeding and thereby avert child morbidity and mortality. SEARCH METHODS: Using Cochrane Collaboration search methods in conjunction with appropriate search terms, we identified relevant studies from January 1, 1994 to January 14, 2014 by searching databases including Cochrane CENTRAL, EMBASE and PubMed, LILACS, and Web of Science/Web of Social Science. SELECTION CRITERIA: Randomized controlled trials in which HIV-infected mothers breastfed their infants, and in which the mothers used antiretroviral prophylaxis while breastfeeding their children or their children received antiretroviral prophylaxis for at least four weeks while breastfeeding, were included. DATA COLLECTION AND ANALYSIS: Abstracts of all trials identified were examined independently by two authors. We identified 15,922 references and examined 81 in detail. Data were abstracted independently using a standardized form. MAIN RESULTS: Seven RCTs were included in the review.One trial compared triple antiretroviral prophylaxis during pregnancy and breastfeeding with short antiretroviral prophylaxis to given to the mother to prevent mother-to-child transmission of HIV. At 12 months, the risks of HIV transmission, and of HIV transmission or death, were lower, but there was no difference in infant mortality alone in the triple arm versus the short arm. Using the GRADE methodology, evidence quality for outcomes in this trial was generally low to moderate.One trial compared six months of breastfeeding using zidovudine, lamivudine, and lopinavir/ritonavir versus zidovudine, lamivudine, and abacavir from 26-34 weeks gestation. At six months, there was no difference in risk of infant HIV infection, infant death, or infant HIV infection or death between the two groups. Evidence quality for outcomes in this trial was generally very low to low.One trial of single dose nevirapine versus six weeks of infant zidovudine found the risk of HIV infection at 12 weeks to be greater in the zidovudine arm than in the single dose nevirapine arm. Evidence quality for outcomes in this trial was generally very low.One multi-country trial compared single dose nevirapine and six weeks of infant nevirapine. After 12 months, infants in the extended nevirapine group had a lower risk of infant mortality compared with the control. There was no difference in the risk of HIV infection or death or in HIV transmission alone in the extended nevirapine group compared with the control. Evidence quality for outcomes in this trial was generally low to moderate.One trial compared single dose nevirapine plus one week zidovudine; the control regimen plus nevirapine up to 14 weeks; or the control regimen with dual prophylaxis up to 14 weeks. At 24 months, the extended nevirapine regimen group had a lower risk of HIV transmission and of HIV transmission or death vs. the control. There was no difference in infant mortality alone. Compared with controls, the dual prophylaxis group had a lower risk of HIV transmission and of HIV transmission or death, but no difference in infant mortality alone. There was no difference in these outcomes between the two intervention arms. Evidence quality for outcomes in this trial was generally moderate to high.One trial compared six weeks of nevirapine with six months of nevirapine. Among infants of mothers not using highly active antiretroviral therapy, there was no difference in risk of HIV infection among the six month nevirapine group versus the six week nevirapine group. Evidence quality for outcomes in this trial was generally low to moderate.One trial compared a maternal triple-drug antiretroviral regimen, infant nevirapine, or neither intervention. Infants in the maternal prophylaxis arm were at lower risk for HIV, and HIV infection or death when compared with the control group. There was no difference in the risk of infant mortality alone. Infants with extended prophylaxis had a lower risk of HIV infection and of HIV infection or death versus the control group infants. There was no difference in the risk of infant mortality alone in the extended infant nevirapine group versus the control. There was no difference in HIV infection, infant mortality, and HIV infection or death between the maternal and extended infant prophylaxis groups. Evidence quality for outcomes in this trial was generally low to moderate. AUTHORS' CONCLUSIONS: Antiretroviral prophylaxis, whether used by the HIV-infected mother or the HIV-exposed infant while breastfeeding, is efficacious in preventing mother-to-child transmission of HIV. Further research is needed regarding maternal resistance and response to subsequent antiretroviral therapy after maternal prophylaxis. An ongoing trial (IMPAACT 1077BF) compares the efficacy and safety of maternal triple antiretroviral prophylaxis versus daily infant nevirapine for prevention of mother-to-child transmission through breastfeeding.

RESUMO

We evaluated the impact of language concordance-clinician or public health worker fluency in a patient's primary language-on coronavirus disease 2019 (COVID-19) contact tracing outcomes among 2668 Spanish-speaking adults in San Francisco. Language concordance was associated with 20% greater odds of COVID-19 testing and 53% greater odds of support service referrals.

RESUMO

People living with HIV often have unmet needs for sexual and reproductive health (SRH) services. We present results of a systematic review of studies offering SRH services targeted to people living with HIV. Studies were selected from a broader SRH and HIV linkages review. Inclusion criteria included: (1) peer-reviewed journal articles with a pre-post or multiple-arm study design; (2) reported post-intervention evaluation data; and (3) published 1 January 1990 through 31 December 2007. Nine studies were identified with an average rigour score of 5.1 out of 9. Services included family planning (one study), sexually transmitted infection (STI) services (two studies), combined family planning and STI services (three studies) and multiple services (three studies). The review identified mostly positive effects on the outcomes measured, including condom and contraceptive use and quality of services. Yet gaps remain in the research to establish the best approaches for addressing needs and choices of people living with HIV. There is a need for high-quality intervention studies to determine the most successful and cost-effective strategies for providing SRH services to people living with HIV.

RESUMO

BACKGROUND: Serological tests can distinguish recent (in the prior 12 months) from long-term HIV infection. Integrating recency testing into routine HIV testing services (HTS) can provide important information on transmission clusters and prioritize clients for partner testing. This study assessed the feasibility and use of integrating HIV recency into routine testing. METHODS: We conducted a multi-method study at 14 facilities in Kenya, and key informant interviews with health care providers. We abstracted clinical record data, collected specimens, tested specimens for recent infection, returned results to participants, and conducted a follow-up survey for those recently infected. RESULTS: From March to October 2018, we enrolled 532 clients who were diagnosed HIV-positive for the first time. Of these, 46 (8.6%) were recently infected. Women aged 15-24 years had 2.9 (95% confidence interval: 1.46 to 5.78) times higher adjusted odds of recent infection compared with 15-24-year-old men and those tested within the past 12 months having 2.55 (95% confidence interval: 0.38 to 4.70) times higher adjusted odds compared with those tested ≥12 months previously. Fourteen of 17 providers interviewed found the integration of recency testing into routine HTS services acceptable and feasible. Among clients who completed the follow-up interview, most (92%) felt that the recency results were useful. CONCLUSIONS: Integrating recent infection testing into routine HTS services in Kenya is feasible and largely acceptable to clients and providers. More studies should be done on possible physical and social harms related to returning results, and the best uses of the recent infection data at an individual and population level.

RESUMO

OBJECTIVES: This analysis assessed the impact of undisclosed HIV infection and antiretroviral therapy (ART) on national estimates of diagnosed HIV and ART coverage in Kenya. METHODS: HIV-positive dried blood spot samples from Kenya's second AIDS Indicator Survey were tested for an antiretroviral biomarker by liquid chromatography-tandem mass spectrometry. Weighted estimates of diagnosed HIV and ART coverage based on self-report were compared with those corrected for undisclosed HIV infection and ART use based on antiretroviral test results. Multivariate analysis determined factors associated with undisclosed HIV infection and ART use among persons on ART. RESULTS: The antiretroviral biomarker was detected in 42.5% [confidence interval (CI) 37.4-47.7] of HIV-infected persons. Antiretroviral drugs were present in 90.7% (CI 86.1-95.2) of HIV-infected persons reporting HIV-positive status and receiving ART, 66.7% (CI 59.9-73.4) reporting HIV-positive status irrespective of ART use, 21.0% (CI 13.4-28.6) reporting HIV-negative status, and 19.3% (CI 9.0-29.5) reporting no previous HIV test. After correcting for undisclosed HIV infection and ART use, diagnosed HIV increased from 46.9 to 57.2% and ART coverage increased from 31.8 to 42.8%. Undisclosed HIV infection while on ART was associated with being aged 25-39 years and not visiting a health provider in the past year, while younger age and higher wealth were associated with undisclosed ART use. CONCLUSION: Substantial levels of undisclosed HIV infection and ART use among persons on ART were observed, resulting in diagnosed HIV underestimated by approximately 112000 persons and ART coverage by approximately 131000 persons. Supplementing self-reported ART status with objective measures of ART use in national population-based serosurveys can improve monitoring of HIV diagnosis and treatment targets in countries.

RESUMO

BACKGROUND: The international community agrees that the Millennium Development Goals will not be achieved without ensuring universal access to both sexual and reproductive health (SRH) services and HIV/AIDS prevention, treatment, care and support. Recently, there has been increasing awareness and discussion of the possible benefits of linkages between SRH and HIV programmes at the policy, systems and service delivery levels. However, the evidence for the efficacy of these linkages has not been systematically assessed. METHODS: We conducted a systematic review of the evidence for interventions linking SRH and HIV. Structured methods were employed for searching, screening and data extraction. Studies from 1990 to 2007 reporting pre-post or multi-arm evaluation data from SRH-HIV linkage interventions were included. Study design rigour was scored on a nine-point scale. Unpublished programme reports were gathered as "promising practices". RESULTS: Of more than 50,000 citations identified, 185 studies were included in the review and 35 were analyzed. These studies had heterogeneous interventions, populations, objectives, study designs, rigour and measured outcomes. SRH-HIV linkage interventions were generally considered beneficial and feasible. The majority of studies showed improvements in all outcomes measured. While there were some mixed results, there were very few negative findings. Generally, positive effects were shown for key outcomes, including HIV incidence, sexually transmitted infection incidence, condom use, contraceptive use, uptake of HIV testing and quality of services. Promising practices (n = 23) tended to evaluate more recent and more comprehensive programmes. Factors promoting effective linkages included stakeholder involvement, capacity building, positive staff attitudes, non-stigmatizing services, and engagement of key populations. CONCLUSIONS: Existing evidence provides support for linkages, although significant gaps in the literature remain. Policy makers, programme managers and researchers should continue to advocate for, support, implement and rigorously evaluate SRH and HIV linkages at the policy, systems and service levels.

RESUMO

OBJECTIVE: To conduct a systematic review of the literature and examine the effectiveness, optimal circumstances, and best practices for strengthening linkages between family planning and HIV interventions. DESIGN: Systematic review of peer-reviewed articles and unpublished program reports ('promising practices') evaluating interventions linking family planning and HIV services. METHODS: Articles were included if they reported post-intervention evaluation results from an intervention linking family planning and HIV services between 1990 and 2007. Systematic methods were used for searching, screening, and data extraction. Quality assessment was conducted using a 9-point rigor scale. RESULTS: Sixteen studies were included in the analysis (10 peer-reviewed studies and six promising practices). Interventions were categorized into six types: family planning services provided to HIV voluntary counseling and testing (VCT) clients, family planning and VCT services provided to maternal and child health clients, family planning services provided to people living with HIV, community health workers provided family planning and HIV services, VCT provided to family planning clinic clients, and VCT and family planning services provided to women receiving postabortion care. Average study design rigor was low (3.25 out of 9). Most studies reported generally positive or mixed results for key outcomes; no negative results were reported. CONCLUSION: Interventions linking family planning and HIV services were generally considered feasible and effective, though overall evaluation rigor was low.
