RESUMO

Late presentation to HIV care, i.e., presenting with < 200 CD4 cells/mL, is associated with higher mortality and worse outcomes. Despite that, a quarter of people living with HIV in Uganda still present late to care. We surveyed Ugandans living with HIV who enrolled in clinic ≤ 90 days prior. We compared groups who presented 'late' with CD4 < 200 and 'early' with CD4 > 350, stratifying by sex. We found men who presented late had higher externalized stigma than early presenters. Thirty-six percent of the entire cohort were depressed. Social support was stronger in late presenters versus early, although weak overall. Social support was inversely correlated with depression, with social support dropping as depression increased. Interventions to improve clinic privacy, reduce stigma, improve social support, and help women disclose their HIV status to male partners are needed to reduce late presentation to HIV care.

RESUMO

Achieving universal HIV test-and-treat will require targeted interventions for those with worse outcomes, including advanced HIV. We conducted qualitative, semi-structured interviews with healthcare workers (HCWs) and people living with HIV (PLWH) at 5 HIV clinics in Kampala, Uganda, to understand barriers to care. PLWH enrolled started/restarted on HIV treatment ≤3 months prior. PLWH were grouped as 1) "ART-experienced" or those restarted therapy after ≥12 months off, 2) ART naïve CD4 count <100 cells/uL "late presenters" or 3) ART naïve CD4 count >350 cells/uL "early presenters". In-depth interviews were conducted in Luganda, translated, and transcribed verbatim. Between May and August 2017, 58 PLWH and 20 HCWs were interviewed. High stigma and low social support emerged as themes among all as barriers to care. Alcohol abuse was a barrier for men. Fear of domestic violence and abandonment were barriers for women, limiting disclosure of their HIV status to their male partners. Clinic factors such as rapport with staff, distance, efficiency, and privacy impacted care. Future interventions to decrease delayed ART initiation should target stigma and social support. Assisted disclosure, contact tracing, and alcohol abuse treatment should be implemented. Strengthening client support, reducing wait times, and increasing privacy assurances would improve care-seeking behaviors.

RESUMO

OBJECTIVE: How clinics structure the delivery of antiretroviral therapy (ART) services may influence patient adherence. We assessed the relationship between models of HIV care delivery and adherence as measured by medication possession ratio (MPR) among treatment-experienced adults in Tanzania, Uganda and Zambia. METHODS: Eighteen clinics were grouped into three models of HIV care. Model 1-Traditional and Model 2-Mixed represented task-sharing of clinical services between physicians and clinical officers, distinguished by whether nurses played a role in clinical care; in Model 3-Task-Shifted, clinical officers and nurses shared clinical responsibilities without physicians. We assessed MPR among 3,419 patients and calculated clinic-level MPR summaries. We then calculated the mean differences of percentages and adjusted residual ratio (aRR) of the association between models of care and incomplete adherence, defined as a MPR <90%, adjusting for individual-level characteristics. RESULTS: In the adjusted analysis, patients in Model 1-Traditional were more likely than patients in Model 2-Mixed to have MPR <90% (aRR = 1.60, 95% CI 1-2.48). Patients in Model 1-Traditional were no more likely than patients in Model 3-Task-Shifted to have a MPR <90% (aRR = 1.58, 95% 0.88-2.85). There was no evidence of differences in MPR <90% between Model 2-Mixed and Model 3-Task-Shifted (aRR = 0.99, 95% CI 0.59-1.66). CONCLUSION: Non-physician-led ART programmes were associated with adherence levels as good as or better than physician-led ART programmes. Additional research is needed to optimise models of care to support patients on lifelong treatment.

RESUMO

BACKGROUND: Organization of HIV care and treatment services, including clinic staffing and services, may shape clinical and financial outcomes, yet there has been little attempt to describe different models of HIV care in sub-Saharan Africa (SSA). Information about the relative benefits and drawbacks of different models could inform the scale-up of antiretroviral therapy (ART) and associated services in resource-limited settings (RLS), especially in light of expanded client populations with country adoption of WHO's test and treat recommendation. METHODS: We characterized task-shifting/task-sharing practices in 19 diverse ART clinics in Tanzania, Uganda, and Zambia and used cluster analysis to identify unique models of service provision. We ran descriptive statistics to explore how the clusters varied by environmental factors and programmatic characteristics. Finally, we employed the Delphi Method to make systematic use of expert opinions to ensure that the cluster variables were meaningful in the context of actual task-shifting of ART services in SSA. RESULTS: The cluster analysis identified three task-shifting/task-sharing models. The main differences across models were the availability of medical doctors, the scope of clinical responsibility assigned to nurses, and the use of lay health care workers. Patterns of healthcare staffing in HIV service delivery were associated with different environmental factors (e.g., health facility levels, urban vs. rural settings) and programme characteristics (e.g., community ART distribution or integrated tuberculosis treatment on-site). CONCLUSIONS: Understanding the relative advantages and disadvantages of different models of care can help national programmes adapt to increased client load, select optimal adherence strategies within decentralized models of care, and identify differentiated models of care for clients to meet the growing needs of long-term ART patients who require more complicated treatment management.

RESUMO

INTRODUCTION: In accordance with global testing and treatment targets, many countries are seeking ways to reach the "90-90-90" goals, starting with diagnosing 90% of all people with HIV. Quality HIV testing services are needed to enable people with HIV to be diagnosed and linked to treatment as early as possible. It is essential that opportunities to reach people with undiagnosed HIV are not missed, diagnoses are correct and HIV-negative individuals are not inadvertently initiated on life-long treatment. We conducted this systematic review to assess the magnitude of misdiagnosis and to describe poor HIV testing practices using rapid diagnostic tests. METHODS: We systematically searched peer-reviewed articles, abstracts and grey literature published from 1 January 1990 to 19 April 2017. Studies were included if they used at least two rapid diagnostic tests and reported on HIV misdiagnosis, factors related to potential misdiagnosis or described quality issues and errors related to HIV testing. RESULTS: Sixty-four studies were included in this review. A small proportion of false positive (median 3.1%, interquartile range (IQR): 0.4-5.2%) and false negative (median: 0.4%, IQR: 0-3.9%) diagnoses were identified. Suboptimal testing strategies were the most common factor in studies reporting misdiagnoses, particularly false positive diagnoses due to using a "tiebreaker" test to resolve discrepant test results. A substantial proportion of false negative diagnoses were related to retesting among people on antiretroviral therapy. Conclusions HIV testing errors and poor practices, particularly those resulting in false positive or false negative diagnoses, do occur but are preventable. Efforts to accelerate HIV diagnosis and linkage to treatment should be complemented by efforts to improve the quality of HIV testing services and strengthen the quality management systems, particularly the use of validated testing algorithms and strategies, retesting people diagnosed with HIV before initiating treatment and providing clear messages to people with HIV on treatment on the risk of a "false negative" test result.

RESUMO

Traditional healers provide healthcare to a substantial proportion of people living with HIV infection (PLHIV) in high HIV burden countries in sub-Saharan Africa. However, the impact on the health of retained patients visiting traditional healers is unknown. In 2011, a study to asses adherence to anti-retroviral therapy (ART) performed in 18 purposefully selected HIV treatment centers in Tanzania, Zambia and Uganda showed that 'consulting a traditional healer/herbalist because of HIV' was an independent risk factor for incomplete ART adherence. To identify characteristics of PLHIV on ART who were also consulting traditional healers, we conducted a secondary analysis of the data from this study. It was found that 260 (5.8%) of the 4451 patients enrolled in the study had consulted a traditional healer during the last three months because of HIV. In multivariable analysis, patients with fewer HIV symptoms, those who had been on ART for >5.3 years and those from Tanzania were more likely to have consulted a traditional healer. However, at the time of the study, there was a famous healer in Manyara district, Loliondo village of Tanzania who claimed his herbal remedy was able to cure all chronic diseases including HIV. HIV treatment programs should be aware that patients with fewer HIV symptoms, those who have been on ART for five or more years, and patients attending ART centers near famous traditional healers are likely to consult traditional healers. Such patients may need more support or counseling about the risks of both stopping ART and poor adherence. Considering the realities of inadequate human resources for health and the burden of disease caused by HIV in sub-Saharan Africa, facilitating a collaboration between allopathic and traditional health practitioners is recommended.

RESUMO

INTRODUCTION: Influenza surveillance was conducted in Uganda from October 2008 to December 2014 to identify and understand the epidemiology of circulating influenza strains in out-patient clinic attendees with influenza-like illness and inform control strategies. METHODOLOGY: Surveillance was conducted at five hospital-based sentinel sites. Nasopharyngeal and/or oropharyngeal samples, epidemiological and clinical data were collected from enrolled patients. Real-time reverse transcription polymerase chain reaction (RT-PCR) was performed to identify and subtype influenza strains. Data were double-entered into an Epi Info 3.5.3 database and exported to STATA 13.0 software for analysis. RESULTS: Of the 6,628 patient samples tested, influenza virus infection was detected in 10.4% (n = 687/6,628) of the specimens. Several trends were observed: influenza circulates throughout the year with two peaks; the major one from September to November and a minor one from March to June. The predominant strains of influenza varied over the years: Seasonal Influenza A(H3) virus was predominant from 2008 to 2009 and from 2012 to 2014; Influenza A(H1N1)pdm01 was dominant in 2010; and Influenza B virus was dominant in 2011. The peaks generally coincided with times of higher humidity, lower temperature, and higher rainfall. CONCLUSION: Influenza circulated throughout the year in Uganda with two major peaks of outbreaks with similar strains circulating elsewhere in the region. Data on the circulating strains of influenza and its patterns of occurrence provided critical insights to informing the design and timing of influenza vaccines for influenza prevention in tropical regions of sub-Saharan Africa.

RESUMO

OBJECTIVES: To identify the reasons patients miss taking their antiretroviral therapy (ART) and the proportion who miss their ART because of symptoms; and to explore the association between symptoms and incomplete adherence. METHODS: Secondary analysis of data collected during a cross-sectional study that examined ART adherence among adults from 18 purposefully selected sites in Tanzania, Uganda, and Zambia. We interviewed 250 systematically selected patients per facility (≥ 18 years) on reasons for missing ART and symptoms they had experienced (using the HIV Symptom Index). We abstracted clinical data from the patients' medical, pharmacy, and laboratory records. Incomplete adherence was defined as having missed ART for at least 48 consecutive hours during the past 3 months. RESULTS: Twenty-nine percent of participants reported at least one reason for having ever missed ART (1278/4425). The most frequent reason was simply forgetting (681/1278 or 53%), followed by ART-related hunger or not having enough food (30%), and symptoms (12%). The median number of symptoms reported by participants was 4 (IQR: 2-7). Every additional symptom increased the odds of incomplete adherence by 12% (OR: 1.1, 95% CI: 1.1-1.2). Female participants and participants initiated on a regimen containing stavudine were more likely to report greater numbers of symptoms. CONCLUSIONS: Symptoms were a common reason for missing ART, together with simply forgetting and food insecurity. A combination of ART regimens with fewer side effects, use of mobile phone text message reminders, and integration of food supplementation and livelihood programmes into HIV programmes, have the potential to decrease missed ART and hence to improve adherence and the outcomes of ART programmes.

RESUMO

Equitable access to antiretroviral therapy (ART) for men and women with human immunodeficiency virus (HIV) infection is a principle endorsed by most countries and funding bodies, including the U.S. President's Emergency Plan for AIDS (acquired immunodeficiency syndrome) Relief (PEPFAR) (1). To evaluate gender equity in ART access among adults (defined for this report as persons aged ≥15 years), 765,087 adult ART patient medical records from 12 countries in five geographic regions* were analyzed to estimate the ratio of women to men among new ART enrollees for each calendar year during 2002-2013. This annual ratio was compared with estimates from the Joint United Nations Programme on HIV/AIDS (UNAIDS)(†) of the ratio of HIV-infected adult women to men in the general population. In all 10 African countries and Haiti, the most recent estimates of the ratio of adult women to men among new ART enrollees significantly exceeded the UNAIDS estimates for the female-to-male ratio among HIV-infected adults by 23%-83%. In six African countries and Haiti, the ratio of women to men among new adult ART enrollees increased more sharply over time than the estimated UNAIDS female-to-male ratio among adults with HIV in the general population. Increased ART coverage among men is needed to decrease their morbidity and mortality and to reduce HIV incidence among their sexual partners. Reaching more men with HIV testing and linkage-to-care services and adoption of test-and-treat ART eligibility guidelines (i.e., regular testing of adults, and offering treatment to all infected persons with ART, regardless of CD4 cell test results) could reduce gender inequity in ART coverage.

RESUMO

OBJECTIVES: To characterize antiretroviral therapy (ART) adherence across different programmes and examine the relationship between individual and programme characteristics and incomplete adherence among ART clients in sub-Saharan Africa. DESIGN: A cross-sectional study. METHODS: Systematically selected ART clients (≥18 years; on ART ≥6 months) attending 18 facilities in three countries (250 clients/facility) were interviewed. Client self-reports (3-day, 30-day, Case Index ≥48 consecutive hours of missed ART), healthcare provider estimates and the pharmacy medication possession ratio (MPR) were used to estimate ART adherence. Participants from two facilities per country underwent HIV RNA testing. Optimal adherence measures were selected on the basis of degree of association with concurrent HIV RNA dichotomized at less than or greater/equal to 1000 copies/ml. Multivariate regression analysis, adjusted for site-level clustering, assessed associations between incomplete adherence and individual and programme factors. RESULTS: A total of 4489 participants were included, of whom 1498 underwent HIV RNA testing. Nonadherence ranged from 3.2% missing at least 48 consecutive hours to 40.1% having an MPR of less than 90%. The percentage with HIV RNA at least 1000 copies/ml ranged from 7.2 to 17.2% across study sites (mean = 9.9%). Having at least 48 consecutive hours of missed ART was the adherence measure most strongly related to virologic failure. Factors significantly related to incomplete adherence included visiting a traditional healer, screening positive for alcohol abuse, experiencing more HIV symptoms, having an ART regimen without nevirapine and greater levels of internalized stigma. CONCLUSION: Results support more in-depth investigations of the role of traditional healers, and the development of interventions to address alcohol abuse and internalized stigma among treatment-experienced adult ART patients.

RESUMO

Although scale-up of antiretroviral therapy (ART) since 2005 has contributed to declines of about 30% in the global annual number of human immunodeficiency (HIV)-related deaths and declines in global HIV incidence, estimated annual HIV-related deaths among adolescents have increased by about 50% and estimated adolescent HIV incidence has been relatively stable. In 2012, an estimated 2,500 (40%) of all 6,300 daily new HIV infections occurred among persons aged 15-24 years. Difficulty enrolling adolescents and young adults in ART and high rates of loss to follow-up (LTFU) after ART initiation might be contributing to mortality and HIV incidence in this age group, but data are limited. To evaluate age-related ART retention challenges, data from retrospective cohort studies conducted in seven African countries among 16,421 patients, aged ≥15 years at enrollment, who initiated ART during 2004-2012 were analyzed. ART enrollment and outcome data were compared among three groups defined by age at enrollment: adolescents and young adults (aged 15-24 years), middle-aged adults (aged 25-49 years), and older adults (aged ≥50 years). Enrollees aged 15-24 years were predominantly female (81%-92%), commonly pregnant (3%-32% of females), unmarried (54%-73%), and, in four countries with employment data, unemployed (53%-86%). In comparison, older adults were more likely to be male (p<0.001), employed (p<0.001), and married, (p<0.05 in five countries). Compared with older adults, adolescents and young adults had higher LTFU rates in all seven countries, reaching statistical significance in three countries in crude and multivariable analyses. Evidence-based interventions to reduce LTFU for adolescent and young adult ART enrollees could help reduce mortality and HIV incidence in this age group.

RESUMO

BACKGROUND: In February 2012, the Lesotho Ministry of Health launched a national voluntary medical male circumcision (VMMC) program. To assess the motivations for seeking VMMC, a cross-sectional mixed methods study was conducted among clients aged 18 years and older at four sites. METHODS: A total of 161 men participated in individual survey interviews and 35 participated in four focus group discussions. RESULTS: Men sought medical circumcision for the following main reasons: protection against HIV (73%), protection from other sexually transmitted infections (62%), and improved penile hygiene (47%). Forty percent learned about VMMC through friends who had already accessed services. According to these men, perceived concerns hindering service uptake include fear of pain (57%), a female provider (18%), and "compulsory" HIV testing (15%). CONCLUSIONS: The study provides important insights into the motivations of clients seeking VMMC services. Findings can be used by the national VMMC program to attract more clients and address barriers to uptake.

RESUMO

OBJECTIVES: We assessed retention and predictors of attrition (recorded death or loss to follow-up) in antiretroviral treatment (ART) clinics in Tanzania, Uganda and Zambia. METHODS: We conducted a retrospective cohort study among adults (≥18 years) starting ART during 2003-2010. We purposefully selected six health facilities per country and randomly selected 250 patients from each facility. Patients who visited clinics at least once during the 90 days before data abstraction were defined as retained. Data on individual and programme level risk factors for attrition were obtained through chart review and clinic manager interviews. Kaplan-Meier curves for retention across sites were created. Predictors of attrition were assessed using a multivariable Cox-proportional hazards model, adjusted for site-level clustering. RESULTS: From 17 facilities, 4147 patients were included. Retention ranged from 52.0% to 96.2% at 1 year to 25.8%-90.4% at 4 years. Multivariable analysis of ART initiation characteristics found the following independent risk factors for attrition: younger age [adjusted hazard ratio (aHR) and 95% confidence interval (95%CI) = 1.30 (1.14-1.47)], WHO stage 4 ([aHR (95% CI): 1.56 (1.29-1.88)], >10% bodyweight loss [aHR (95%CI) = 1.17 (1.00-1.38)], poor functional status [ambulatory aHR (95%CI) = 1.29 (1.09-1.54); bedridden aHR1.54 (1.15-2.07)], and increasing years of clinic operation prior to ART initiation in government facilities [aHR (95%CI) = 1.17 (1.10-1.23)]. Patients with higher CD4 cell count were less likely to experience attrition [aHR (95%CI) = 0.88 (0.78-1.00)] for every log (tenfold) increase. Sites offering community ART dispensing [aHR (95%CI) = 0.55 (0.30-1.01) for women; 0.40 (0.21-0.75) for men] had significantly less attrition. CONCLUSIONS: Patient retention to an individual programme worsened over time especially among males, younger persons and those with poor clinical indicators. Community ART drug dispensing programmes could improve retention.

RESUMO

The inconclusive results of past trials and recent findings of partial protection of Tenofovir 1% gel underscore the need to better understand product adherence in microbicide trials. This study aimed to identify factors predicting couples' ability to sustain topical gel and condom use during clinical trial participation. We enrolled 100 Indian participants of a randomized, controlled safety trial of Tenofovir 1% gel (CT cohort) and 100 similar women who were ineligible or declined trial participation (NCT cohort). Compared to the NCT cohort, CT women reported higher baseline condom use, more positive attitudes towards condoms and higher levels of protection efficacy. While NCT condom use remained low, CT condom use increased dramatically during the study. Reported gel consistency was higher than condom consistency. Individual and couple-related factors predicted condom consistency and interest in future gel use, but not gel consistency. Findings could inform trial recruitment strategies and product introduction.

RESUMO

This study reports on the acceptability of 1% tenofovir microbicide gel among participants randomised to the coitally-associated use (n = 50) or daily use (n = 50) arms of a Phase II clinical trial in Pune, India. In a 6-month follow-up study, information on behavioural domains was collected on a 6-point Likert scale and gel acceptability was measured on a 5-point Likert scale. Random intercept logistic modelling was performed to examine the simultaneous effects of study arm, follow-up time, sociodemographic factors and behavioural domains on gel acceptability. The mean age of female participants was 32.7 years. Women in both study arms had similar sociodemographic profiles. Women liked features such as easy use of the gel and its protective effect against HIV. Messiness was the most disliked feature. Gel acceptability increased during subsequent follow-up visits in both arms, especially in the coitally-associated use arm. Non-acceptability of the gel was almost two and a half times higher in daily users (adjusted odds ratio 2.55, 95% CI 1.18-5.51; p = 0.017). Acceptability differed significantly between the two study arms at 2 months (68% vs 40%; p = 0.006) and 6 months (64% vs 46%; p = 0.07). Acceptability was significantly lower in those participants who reported 'messiness' as the most disliked feature (odds ratio 2.42, 95% CI 1.02-5.72; p = 0.045). In conclusion, microbicides were more acceptable in coitally-associated users than in daily users. Leakage was a problem that requires attention. Positioning of the product in a setting such as India where the majority of decision-making is done by men would need extensive and systematic education of men.

RESUMO

Research suggests that the HIV/AIDS epidemic has spread to monogamous women in India. Gender inequalities prevent women from asserting control over the circumstances that increase their vulnerability to infection. Men control most of the sexual decision-making. The present study explores views on use of microbicides by men and circumstances in which they might find microbicide use with their wives acceptable. Progressive in-depth interviews were conducted among 15 consenting men from Pune, India. Men felt that women with identifiable HIV risk, such as being a sex worker, having an HIV infected husbands or being educated; were more likely to use microbicides. Most high-risk men would permit or force their wives to use microbicides and had a higher intention to use microbicides compared with low-risk men probably due to perceived susceptibility. The majority of men with previous experience of microbicide use mentioned that privacy was important for gel use. Most low-risk men believed that they would be angry with covert gel use by their wives. They felt that covert use was impossible since their wives were under their control and they would notice the gel due to a change in their sexual experience. Low-risk men also opined that husband's permission was not required if he was HIV-infected or having extra-marital sex. Some men stressed the need for exercising sexual control while women inserted gel before sex. Men's risk-perception, knowledge about their safety concerns, as well as their behavior may affect acceptability of gel use, hence men's involvement and cooperation is imperative for microbicide gel use by women in India.

RESUMO

Few studies in Africa provide detailed descriptions of the vulnerabilities of female sex workers (FSW) to sexual and physical violence, and how this impacts on their HIV risk. This qualitative study documents FSW's experiences of violence in Mombasa and Naivasha, Kenya. Eighty-one FSW who obtained clients from the streets, transportation depots, taverns, discos and residential areas were recruited through local sex workers trained as peer counsellors to participate in eight focus-group discussions. Analysis showed the pervasiveness of sexual and physical violence among FSW, commonly triggered by negotiation around condoms and payment. Pressing financial needs of FSW, gender-power differentials, illegality of trading in sex and cultural subscriptions to men's entitlement for sex sans money underscore much of this violence. Sex workers with more experience had developed skills to avoid threats of violence by identifying potentially violent clients, finding safer working areas and minimising conflict with the police. Addressing violence and concomitant HIV risks and vulnerabilities faced by FSW should be included in Kenya's national HIV/AIDS strategic plan. This study indicates the need for multilevel interventions, including legal reforms so that laws governing sex work promote the health and human rights of sex workers in Kenya.

RESUMO

BACKGROUND AND OBJECTIVES: Female sex workers (FSWs) are thought to be at heightened risk for unintended pregnancy, although sexual and reproductive health interventions reaching these populations are typically focused on the increased risk of sexually transmitted infections. The objective of this study of FSWs in Kenya is to document patterns of contraceptive use and unmet need for contraception. METHODS: This research surveys a large sample of female sex workers (N = 597) and also uses qualitative data from focus group discussions. RESULTS: The reported level of modern contraceptives in our setting was very high. However, like in other studies, we found a great reliance on male condoms, coupled with inconsistent use at last sex, which resulted in a higher potential for unmet need for contraception than the elevated levels of modern contraceptives might suggest. Dual method use was also frequently encountered in this population and the benefits of this practice were clearly outlined by focus group participants. CONCLUSION: These findings suggest that the promotion of dual methods among this population could help meet the broader reproductive health needs of FSWs. Furthermore, this research underscores the necessity of considering consistency of condom use when estimating the unmet or undermet contraceptive needs of this population.
