Roles and responsibilities of expert clients in adolescent HIV service delivery in Eswatini: a conventional content analysis.

We aimed to elucidate the specific roles and responsibilities of expert clients in service delivery among adolescents living with HIV in Eswatini, and to provide recommendations for enhancing adolescent service provision among expert clients and similar lay health workers throughout low- and middle-income countries. An exploratory qualitative descriptive methodology using conventional content analysis was used to meet our study aims. We recruited 20 expert clients and 12 key informants (programme managers, programme coordinators and nurses) to participate in semi-structured interviews, and we arranged four focus group discussions among adolescents living with HIV with seven to ten participants per focus group. Adherence counselling in clinical and community settings was considered paramount to the roles and responsibilities of expert clients with regard to adolescent-specific HIV service delivery. The following recommendations were made to enhance expert client service delivery practices among adolescents: (1) training in adolescent developmental, sexual and reproductive needs; (2) training to enhance clinical knowledge and skills; (3) additional work equipment and compensation; and d) more parent and guardian engagement in their work. While expert clients meet the needs of adolescents living with HIV in several capacities, they require additional resources, skills and training to improve their work, especially in the realm of sexual and reproductive health. Future research is needed to evaluate the impact of expert client service delivery on adolescent health outcomes.

Challenges encountered by human immunodeficiency virus positive pregnant women on taking antiretrovirals in a public health unit of the Manzini region, Swaziland.

In Swaziland, the Ministry of Health adopted the prevention of mother-to-transmission (PMTCT) Option A as a feasible and less costly way to expand the PMTCT services nationwide. Despite major success since the programme started, some barriers, such as the challenge of follow-up care for human immunodeficiency virus (HIV)-positive pregnant mothers still exist. The present study aimed to describe the challenges that HIV-positive pregnant mothers encountered on taking antiretrovirals (ARVs) in a health unit of the Manzini region, Swaziland. A qualitative, exploratory and descriptive research design was used, and data were collected through semi-structured individual interviews and field notes. Purposive sampling was used to select the study site and the population. Permission was requested from the participants to record the interviews. The study population were HIV-positive pregnant mothers, aged between 18 and 40 years, which were enrolled in the PMTCT B+ programme. The PMTCT B+ programme was perceived as preventing the transfer of HIV transmission from mother to child. It boosts the mother's immune system, prevents opportunistic infections and prolongs life. Challenges of taking ARVs emerged as a theme. The participants displayed knowledge and understanding of the programme, yet discrimination and no support from families and partners were mentioned.

Women's satisfaction with maternity experience at a regional hospital in Swaziland: A cross sectional survey.

Clinical care during labor and childbirth is important, however understanding women's preferences and experiences have become more important in assessing quality health care delivery and maternity services utilization. Knowledge on women's satisfaction will be one of the important steps towards solving maternal and child health problems faced in Swaziland. The aim of the study was to determined maternity experiences and women's demographic characteristics that affect perceived satisfaction with maternity care at a regional hospital in Swaziland. A cross sectional survey using structured interview questionnaire was used to obtain data from 198 women who had a normal childbirth during their postnatal hospital stay. One-way ANOVA and t-test were used to examine association between variables and stepwise multiple linear regression analysis was conducted to identify predictors of satisfaction. The final model indicated that respecting women's description of pain/discomfort, staff kindness, gender of birth assistant, never being alone during labor and woman's education level determined satisfaction with maternity experience, explaining 44.6% of the variation in maternity satisfaction (F= 30.932, p <.001). The study findings show the importance of provider related factors (interpersonal aspect of care, gender of provider) and consideration of woman's education on satisfaction with care during intrapartum and postpartum.

"They have been neglected for a long time": a qualitative study on the role and recognition of rural health motivators in the Shiselweni region, Eswatini.

BACKGROUND: Community health workers (CHWs) are increasingly engaged to address human resource shortages and fill primary healthcare gaps. In Eswatini, a cadre of CHWs called Rural Health Motivators (RHM) was introduced in 1976 to respond to key public health challenges. However, the emergence of health needs, particularly HIV/TB, has been met with inadequate programme amendments, and the role of RHMs has become marginalised following the addition of other CHWs supported by non-governmental organisations. This study was implemented to understand the role of RHMs in decentralised HIV/TB activities. In this paper, we explore the findings in relation to the recognition of RHMs and the programme. METHODS: This exploratory qualitative study utilised individual in-depth interviews, group and focus group discussions, participatory methods (utilising a game format) and observations. Participants were purposively selected and comprised RHM programme implementers, community stakeholders and local and non-governmental personnel. Data collection took place between August and September 2019. Interviews were conducted in English or siSwati and transcribed. SiSwati interviews were translated directly into English. All interviews were audio-recorded, manually coded and thematically analysed. Data was validated through methodical triangulation. RESULTS: Suboptimal organisational structure and support, primarily insufficient training and supervision for activities were factors identified through interviews and observation activities. Significant confusion of the RHM role was observed, with community expectations beyond formally endorsed tasks. Community participants expressed dissatisfaction with receiving health information only, preferring physical assistance in the form of goods. Additionally, gender emerged as a significant influencing factor on the acceptability of health messages and the engagement of RHMs with community members. Expectations and structurally limiting factors shape the extent to which RHMs are recognised as integral to the health system, at all social and organisational levels. CONCLUSIONS: Findings highlight the lack of recognition of RHMs and the programme at both community and national levels. This, along with historical neglect, has hindered the capacity of RHMs to successfully contribute to positive health outcomes for rural communities. Renewed attention and support mechanisms for this cadre are needed. Clarification of the RHM role in line with current health challenges and clearer role parameters is essential.

Prevalence of abnormal glucose metabolism among adults attending an outpatient department at a tertiary referral hospital in Swaziland: a cross-sectional study.

BACKGROUND: The exact prevalence of type 2 diabetes mellitus (T2DM) and pre-diabetes in Swaziland remains unknown. Estimates suggest that the prevalence rate of type 2 diabetes mellitus is between 2.5 and 6.0% in Swaziland. The disparity in these estimates is due to a lack of quality data but the prevalence of diabetes is increasing in Swaziland. This study estimates the prevalence of type 2 diabetes mellitus and pre-diabetes among patients in a tertiary hospital in Manzini, Swaziland. METHODS: A cross-sectional observational survey was used to estimate the crude and age-adjusted prevalence rates of diabetes and pre-diabetes (impaired fasting glucose (IFG) and impaired glucose tolerance (IGT)) in the Manzini regional referral hospital of Swaziland. Diabetes was defined as a fasting blood glucose (FBG) ≥ 7.0 mmol/L (126 mg/dL) and pre-diabetes was defined as an FBG of 6.1-6.9 mmol/L (110-125 mg/dL) and an FBG < 7.0 mmol/L (< 126 mg/dL), respectively for IFG and IGT. A random sample of 385 participants was used. Data analysis was done using SPSS version 26 and the level of statistical significance was set at α < 0.05. RESULTS: The crude prevalence of type 2 diabetes mellitus and pre-diabetes was 7.3% [95% CI 4.9-10.3] and 6.5% [95% CI 4.2-9.4], respectively, with clear gender differences in the prevalence of diabetes (men 1.6% vs women 5.7%, p = 0.001). On the other hand, significantly more men (3.6%) had pre-diabetes than women (2.9%) (p = 0.004). The overall age-adjusted prevalence rates of type 2 diabetes mellitus and pre-diabetes were 3.9 and 3.8%, respectively. Among the diabetic group, 3 (10.7%) had known T2DM, whereas 25 (89.3%) were newly diagnosed during the study. Advancing age, gender, raised blood pressure, abnormal body mass index, and wealth index were significant risk factors for T2DM or prediabetes. CONCLUSION: The prevalence of type 2 diabetes mellitus among adult outpatients in the Raleigh Fitkin Memorial hospital was higher than previously reported in the health facility in Manzini; suggesting the need for routine T2DM screening at outpatient departments.

Decentralising NCD management in rural southern Africa: evaluation of a pilot implementation study.

BACKGROUND: The prevalence of non-communicable diseases, and associated morbidity and mortality, is increasing rapidly in low and middle-income countries where health systems often have limited access and lower quality of care. The intervention was to decentralise uncomplicated non-communicable disease (NCD) care from a hospital to nurse practitioners in health centres in a poor rural district in Eswatini, southern Africa. The objective of this study was to assess the feasibility and impact of decentralised care for NCDs within nurse-led clinics in order improve access and inform healthcare planning in Eswatini and similar settings. METHODS: In collaboration with the Eswatini Ministry of Health, we developed and implemented a package of interventions to support nurse-led delivery of care, including: clinical desk-guide for hypertension and diabetes, training modules, treatment cards and registries and patient leaflets. Ten community clinics in the Lubombo Region of Eswatini were randomly selected to be trained to deliver NCD care for a period of 18 months. Observational data on follow-up rates, blood pressure (BP), glucose etc. were recorded and evaluated. We compared blood pressure and blood glucose measurements between the first and fourth visits and fitted a linear mixed effects model. RESULTS: One thousand one hundred twenty-five patients were recruited to the study. Of these patients, 573 attended for at least 4 appointments. There was a significant reduction in mean BP among hypertensive patients after four visits of 9.9 mmHg systolic and 4.7 mmHg diastolic (p = 0.01), and a non-significant reduction in fasting blood glucose among diabetic patients of 1.2 mmol/l (p = 0.2). Key components of NCD care were completed consistently by nurses throughout the intervention period, including a trend towards patients progressing from monotherapy to dual therapy in accordance with prescribing guidelines. CONCLUSIONS: The findings suggest that management of diabetes and hypertension care in a rural district setting can be safely delivered by nurses in community clinics according to a shared care protocol. Improved access is likely to lead to improved patient compliance with treatment.

Modifiable risk factors associated with non-communicable diseases among adult outpatients in Manzini, Swaziland: a cross-sectional study.

BACKGROUND: Four major non-communicable diseases (NCD), including T2DM, contributed to nearly three-quarters of all deaths worldwide in 2017. Dietary and lifestyle actors associated with NCDs are potentially modifiable. Therefore, this study was conducted to determine the dietary and lifestyle factors associated with T2DM, pre-diabetes, and hypertension among adult outpatients in Manzini, Swaziland. METHODS: A random sample of 385 subjects aged 18 years and above was selected. The data regarding demographics, socio-economic status, lifestyle behaviour, diet, and physical activities were collected. Additionally, participants' anthropometric measurements and vital signs were taken. A biochemical examination was done for fasting plasma glucose, and a 2-h oral glucose tolerance test, where necessary. The Statistical Package for Social Sciences (SPSS) version 26 was used for this data analysis, and the level of statistical significance was set at p < 0.05. RESULTS: A total of 385 (197 men and 188 women) subjects aged 18 years and older participated in the study. The overall prevalence of hypertension was 48.3%, while the prevalence of hypertension stage 1 and 2 were 29.4 and 19%, respectively. Smoking, SES and consumption of sweet drinks, salty processed foods, fruits, and vegetables were significantly associated with T2DM. However, in the multivariate analysis, only consumption of vegetables (p < 0.0001), fruits (p =0.014), sweet drinks (p = 0.042), and salty processed foods (p = 0.005) remained significantly associated with T2DM. Smoking (p = 0.002) and consumption of fruits (p < 0.0001), vegetables (p < 0.0001), and sweet drinks (p = 0.043) were independently associated with pre-diabetes, while the consumption of vegetables (p = 0.002) and salty processed foods (p = 0.003) were the factors independently associated with hypertension. CONCLUSIONS: The factors associated with T2DM, pre-diabetes, and hypertension are potentially modifiable. Therefore, interventions which target lifestyle changes at primary health care and population levels are warranted to address the growing burden of these chronic conditions in Swaziland.

A SARS-CoV-2 Surveillance System in Sub-Saharan Africa: Modeling Study for Persistence and Transmission to Inform Policy.

BACKGROUND: Since the novel coronavirus emerged in late 2019, the scientific and public health community around the world have sought to better understand, surveil, treat, and prevent the disease, COVID-19. In sub-Saharan Africa (SSA), many countries responded aggressively and decisively with lockdown measures and border closures. Such actions may have helped prevent large outbreaks throughout much of the region, though there is substantial variation in caseloads and mortality between nations. Additionally, the health system infrastructure remains a concern throughout much of SSA, and the lockdown measures threaten to increase poverty and food insecurity for the subcontinent's poorest residents. The lack of sufficient testing, asymptomatic infections, and poor reporting practices in many countries limit our understanding of the virus's impact, creating a need for better and more accurate surveillance metrics that account for underreporting and data contamination. OBJECTIVE: The goal of this study is to improve infectious disease surveillance by complementing standardized metrics with new and decomposable surveillance metrics of COVID-19 that overcome data limitations and contamination inherent in public health surveillance systems. In addition to prevalence of observed daily and cumulative testing, testing positivity rates, morbidity, and mortality, we derived COVID-19 transmission in terms of speed, acceleration or deceleration, change in acceleration or deceleration (jerk), and 7-day transmission rate persistence, which explains where and how rapidly COVID-19 is transmitting and quantifies shifts in the rate of acceleration or deceleration to inform policies to mitigate and prevent COVID-19 and food insecurity in SSA. METHODS: We extracted 60 days of COVID-19 data from public health registries and employed an empirical difference equation to measure daily case numbers in 47 sub-Saharan countries as a function of the prior number of cases, the level of testing, and weekly shift variables based on a dynamic panel model that was estimated using the generalized method of moments approach by implementing the Arellano-Bond estimator in R. RESULTS: Kenya, Ghana, Nigeria, Ethiopia, and South Africa have the most observed cases of COVID-19, and the Seychelles, Eritrea, Mauritius, Comoros, and Burundi have the fewest. In contrast, the speed, acceleration, jerk, and 7-day persistence indicate rates of COVID-19 transmissions differ from observed cases. In September 2020, Cape Verde, Namibia, Eswatini, and South Africa had the highest speed of COVID-19 transmissions at 13.1, 7.1, 3.6, and 3 infections per 100,0000, respectively; Zimbabwe had an acceleration rate of transmission, while Zambia had the largest rate of deceleration this week compared to last week, referred to as a jerk. Finally, the 7-day persistence rate indicates the number of cases on September 15, 2020, which are a function of new infections from September 8, 2020, decreased in South Africa from 216.7 to 173.2 and Ethiopia from 136.7 to 106.3 per 100,000. The statistical approach was validated based on the regression results; they determined recent changes in the pattern of infection, and during the weeks of September 1-8 and September 9-15, there were substantial country differences in the evolution of the SSA pandemic. This change represents a decrease in the transmission model R value for that week and is consistent with a de-escalation in the pandemic for the sub-Saharan African continent in general. CONCLUSIONS: Standard surveillance metrics such as daily observed new COVID-19 cases or deaths are necessary but insufficient to mitigate and prevent COVID-19 transmission. Public health leaders also need to know where COVID-19 transmission rates are accelerating or decelerating, whether those rates increase or decrease over short time frames because the pandemic can quickly escalate, and how many cases today are a function of new infections 7 days ago. Even though SSA is home to some of the poorest countries in the world, development and population size are not necessarily predictive of COVID-19 transmission, meaning higher income countries like the United States can learn from African countries on how best to implement mitigation and prevention efforts.

High Genetic Diversity of Plasmodium falciparum in the Low-Transmission Setting of the Kingdom of Eswatini.

BACKGROUND: To better understand transmission dynamics, we characterized Plasmodium falciparum genetic diversity in Eswatini, where transmission is low and sustained by importation. METHODS: Twenty-six P. falciparum microsatellites were genotyped in 66% of confirmed cases (2014-2016; N = 582). Population and within-host diversity were used to characterize differences between imported and locally acquired infections. Logistic regression was used to assess the added value of diversity metrics to classify imported and local infections beyond epidemiology data alone. RESULTS: Parasite population in Eswatini was highly diverse (expected heterozygosity [HE] = 0.75) and complex: 67% polyclonal infections, mean multiplicity of infection (MOI) 2.2, and mean within-host infection fixation index (FWS) 0.84. Imported cases had comparable diversity to local cases but exhibited higher MOI (2.4 vs 2.0; P = .004) and lower mean FWS (0.82 vs 0.85; P = .03). Addition of MOI and FWS to multivariate analyses did not increase discrimination between imported and local infections. CONCLUSIONS: In contrast to the common perception that P. falciparum diversity declines with decreasing transmission intensity, Eswatini isolates exhibited high parasite diversity consistent with high rates of malaria importation and limited local transmission. Estimates of malaria transmission intensity from genetic data need to consider the effect of importation, especially as countries near elimination.

Changes in disclosure, adherence and healthcare interactions after the introduction of immediate ART initiation: an analysis of patient experiences in Swaziland.

INTRODUCTION: There are concerns that immediate ART initiation (regardless of CD4 count) negatively affects HIV status disclosure, ART adherence and healthcare interactions. We assessed changes in these factors after the 'Early access to ART for all' intervention, a universal test-and-treat study in Swaziland. METHODS: We recruited two samples of participants between 2014 and 2017. The first group was interviewed before the intervention (control); the second group at the implementation and 6 months thereafter (intervention). RESULTS: High levels of disclosure to partners (controls and intervention: 94%) and family members (controls: 78%, intervention: 79%) were reported, and high levels of adherence (85% did not miss a dose among the controls, 84% in the intervention group). There were no changes in patients reporting feeling pressured to initiate ART (controls: 10%, intervention: 11%). The quality of interaction with healthcare workers improved after the intervention; healthcare workers explained more often the choice of ART initiation (controls: 88%, intervention: 93%) and the meaning of both CD4 and viral load test results (controls: 15%, intervention: 47%). More patients in the intervention group reported receiving test results (controls: 13%, intervention: 46%). We observed no changes in disclosure, adherence or patient experiences 6 months into the intervention compared to its start. CONCLUSION: Our results suggest that both reported adherence and disclosure levels remain high after the introduction of immediate ART in Swaziland. We observed an improvement in the healthcare interactions, possibly due to training at participating facilities, which will be an important element for a successful roll-out of immediate ART.

OBJECTIF: Il y a des craintes que l'initiation de l'ART immédiat (quel que soit la numération des CD4) affecte négativement la divulgation du statut VIH, l'adhésion au traitement et les interactions avec les soins de santé. Nous avons évalué les modifications de ces facteurs après l'intervention «Accès précoce à l'ART pour tous¼, une étude universelle de dépistage et traitement au Swaziland. MÉTHODES: Nous avons recruté deux échantillons de participants entre 2014 et 2017. Le premier groupe a été interviewé avant l'intervention (témoins), le deuxième groupe lors de l'implémentation et six mois après (intervention). RÉSULTATS: Des niveaux élevés de divulgation aux partenaires (témoin et intervention: 94%) et aux membres de la famille (témoins: 78%, intervention: 79%) ont été rapportés, ainsi que des taux élevés d'adhésion (85% n'ont pas oublié une dose chez les témoins, 84% dans le groupe d'intervention). Aucun changement n'a été observé chez les patients déclarant se sentir poussés à commencer l'ART (témoins: 10%, intervention: 11%). La qualité de l'interaction avec les agents de la santé s'est améliorée après l'intervention; les agents de santé expliquent plus souvent le choix de l'initiation de l'ART (témoins: 88%, intervention: 93%) et la signification des résultats des tests de CD4 et de la charge virale (témoins: 15%, intervention: 47%). Plus de patients du groupe d'intervention ont déclaré avoir reçu les résultats des tests (témoins: 13%, intervention: 46%). Nous n'avons observé aucun changement dans la divulgation, l'adhésion ou l'expérience des patients six mois après le début de l'intervention par rapport à son début. CONCLUSION: Nos résultats suggèrent que les taux d'adhésion et de divulgation rapportés restent élevés après l'introduction de l'ART immédiat au Swaziland. Nous avons observé une amélioration des interactions avec les soins de santé, probablement due à la formation dispensée dans les établissements participants, ce qui constituera un élément important pour le succès du déploiement de l'ART immédiat.

Programmatic outcomes and impact of rapid public sector antiretroviral therapy expansion in adults prior to introduction of the WHO treat-all approach in rural Eswatini.

OBJECTIVES: To assess long-term antiretroviral therapy (ART) outcomes during rapid HIV programme expansion in the public sector of Eswatini (formerly Swaziland). METHODS: This is a retrospectively established cohort of HIV-positive adults (≥16 years) who started first-line ART in 25 health facilities in Shiselweni (Eswatini) between 01/2006 and 12/2014. Temporal trends in ART attrition, treatment expansion and ART coverage were described over 9 years. We used flexible parametric survival models to assess the relationship between time to ART attrition and covariates. RESULTS: Of 24 772 ART initiations, 6% (n = 1488) occurred in 2006, vs. 13% (n = 3192) in 2014. Between these years, median CD4 cell count at ART initiation increased (113-265 cells/mm3 ). The active treatment cohort expanded 8.4-fold, ART coverage increased 8.0-fold (7.1% in 2006 vs. 56.8% in 2014) and 12-month crude ART retention improved from 71% to 86%. Compared with the pre-decentralisation period (2006-2007), attrition decreased by 5% (adjusted hazard ratio [aHR] 0.95, 95% confidence interval 0.88-1.02) during HIV-TB service decentralisation (2008-2010), by 17% (aHR 0.83, 0.75-0.92) during service consolidation (2011-2012), and by 20% (aHR 0.80, 0.71-0.90) during further treatment expansion (2013-2014). The risk of attrition was higher for young age, male sex, pathological baseline haemoglobin and biochemistry results, more toxic drug regimens, WHO III/IV staging and low CD4 cell count; access to a telephone was protective. CONCLUSIONS: Programmatic outcomes improved during large expansion of the treatment cohort and increased ART coverage. Changes in ART programming may have contributed to better outcomes.

OBJECTIFS: Evaluer les résultats du traitement antirétroviral (ART) à long terme durant l'expansion rapide du programme de lutte contre le VIH dans le secteur public d'Eswatini (anciennement Swaziland). MÉTHODES: Il s'agit d'une cohorte établie de manière rétrospective d'adultes VIH positifs (≥ 16 ans) qui ont commencé un ART de première ligne dans 25 établissements de santé à Shiselweni (Eswatini) entre janvier 2006 et décembre 2014. Les tendances temporelles de l'attrition dans l'ART, de l'extension de la couverture ART ont été décrites sur 9 ans. Nous avons utilisé des modèles de survie paramétriques flexibles pour évaluer la relation entre le temps écoulé avant l'attrition dans l'ART et les covariables. RÉSULTATS: Sur 24.772 initiations à l'ART, 6% (n = 1.488) ont eu lieu en 2006 contre 13% (n = 3.192) en 2014. Entre ces années, le nombre médian de cellules CD4 au début du traitement ART a augmenté (113 à 265 cellules/mm3 ). La cohorte de traitement actif a été multipliée par 8,4, la couverture ART par 8,0 (7,1% en 2006 contre 56,8% en 2014) et la rétention brute sous ART est passée de 71% à 86%. Par rapport à la période antérieure à la décentralisation (2006-2007), l'attrition a diminué de 5% (rapport de risque ajusté [aHR]: 0,95, intervalle de confiance à 95%: 0,88 à 1,02) au cours de la décentralisation des services VIH-TB (2008-2010), de 17% (HR: 0,83; 0,75-0,92) lors de la consolidation du service (2011-2012) et de 20% (HR: 0,80; 0,71-0,90) lors de la poursuite de l'extension du traitement (2013-2014). Le risque d'attrition était plus élevé pour le jeune âge, le sexe masculin, les résultats pathologiques de l'hémoglobine initiale et biochimiques, des schémas thérapeutiques plus toxiques, un stade III/IV de l'OMS et une faible numération des cellules CD4; l'accès au téléphone était protecteur. CONCLUSIONS: Les résultats programmatiques se sont améliorés au cours de l'expansion importante de la cohorte de traitement et de l'augmentation de la couverture ART. Les changements apportés au programme ART peuvent avoir contribué à de meilleurs résultats.

Decreased risk of HIV-associated TB during antiretroviral therapy expansion in rural Eswatini from 2009 to 2016: a cohort and population-based analysis.

OBJECTIVES: This paper assesses patient- and population-level trends in TB notifications during rapid expansion of antiretroviral therapy in Eswatini which has an extremely high incidence of both TB and HIV. METHODS: Patient- and population-level predictors and rates of HIV-associated TB were examined in the Shiselweni region in Eswatini from 2009 to 2016. Annual population-level denominators obtained from projected census data and prevalence estimates obtained from population-based surveys were combined with individual-level TB treatment data. Patient- and population-level predictors of HIV-associated TB were assessed with multivariate logistic and multivariate negative binomial regression models. RESULTS: Of 11 328 TB cases, 71.4% were HIV co-infected and 51.8% were women. TB notifications decreased fivefold between 2009 and 2016, from 1341 to 269 cases per 100 000 person-years. The decline was sixfold in PLHIV vs. threefold in the HIV-negative population. Main patient-level predictors of HIV-associated TB were recurrent TB treatment (adjusted odds ratio [aOR] 1.40, 95% confidence interval [CI]: 1.19-1.65), negative (aOR 1.31, 1.15-1.49) and missing (aOR 1.30, 1.11-1.53) bacteriological status and diagnosis at secondary healthcare level (aOR 1.18, 1.06-1.33). Compared with 2009, the probability of TB decreased for all years from 2011 (aOR 0.69, 0.58-0.83) to 2016 (aOR 0.54, 0.43-0.69). The most pronounced population-level predictor of TB was HIV-positive status (adjusted incidence risk ratio 19.47, 14.89-25.46). CONCLUSIONS: This high HIV-TB prevalence setting experienced a rapid decline in TB notifications, most pronounced in PLHIV. Achievements in HIV-TB programming were likely contributing factors.

OBJECTIFS: Ce document évalue les tendances des notifications de la tuberculose (TB) à l'échelle des patients et de la population lors de l'expansion rapide du traitement antirétroviral à Eswatini, où l'incidence de la TB et du VIH est extrêmement élevée. MÉTHODES: Les prédicteurs et les taux de TB associée au VIH à l'échelle des patients et de la population ont été examinés dans la région de Shiselweni à Eswatini de 2009 à 2016. Les dénominateurs annuels à l'échelle de la population obtenus à partir des données de recensement projetées et des estimations de la prévalence obtenues à partir d'enquêtes de population ont été combinés avec des données de traitement de la TB à l'échelle individuel. Les prédicteurs de la TB associée au VIH à l'échelle du patient et de la population ont été évalués à l'aide de modèles de régression logistique multivariée et binomiale négative multivariée. RÉSULTATS: Sur 11.328 cas de TB, 71,4% étaient coinfectés par le VIH et 51,8% étaient des femmes. Les notifications de TB ont été réduites de 5,0 fois entre 2009 et 2016, passant de 1.341 à 269 cas par 100.000 personnes-années. Le déclin était de 6,0 fois chez les PVVIH contre 3,0 fois dans la population négative pour le VIH. Les principaux prédicteurs de la TB associée au VIH à l'échelle des patients étaient les traitements antituberculeux récurrents (rapport de cotes ajusté [aOR] 1,40; intervalle de confiance à 95% [IC]: 1,19 à 1,65), un statut bactériologique négatif (aOR: 1,31; 1,15 à 1,49) et manquant (aOR: 1,30; 1,11 à 1,53) et le diagnostic au niveau des soins de santé secondaires (AOR 1,18; 1,06 à 1,33). Par rapport à 2009, la probabilité de contracter la TB a diminué pour toutes les années, de 2011 (aOR: 0,69; 0,58 à 0,83) à 2016 (aOR: 0,5; 0,43 à 0,69). Le prédicteur le plus prononcé de la TB à l'échelle de la population était le statut VIH-positif (rapport de risque d'incidence ajusté: 19,47; 14,89 à 25,46). CONCLUSIONS: Ce contexte de prévalence élevée de la TB-VIH a connu un déclin rapide du nombre de notifications de TB, plus prononcé chez les PVVIH. Les réalisations dans la programmation VIH-TB étaient probablement des facteurs contributifs.

Stigma and outness about sexual behaviors among cisgender men who have sex with men and transgender women in Eswatini: a latent class analysis.

BACKGROUND: Men who have sex with men (MSM) and transgender women in Sub-Saharan Africa are subjected to high levels of sexual behavior-related stigma, which may affect mental health and sexual risk behaviors. MSM and transgender women who are open about, or have disclosed their sexual behaviors appear to be most affected by stigma. Characterizing the mechanism of action of stigma in potentiating HIV-risks among these key populations is important to support the development of interventions. METHODS: In this study, a total of 532 individuals were recruited across Eswatini (Swaziland) through chain-referral-sampling from October - December 2014, including 419 cisgender MSM and 109 transgender women. Participants were surveyed about demographics, stigma, outness of same-sex practices to family members and healthcare workers, and mental and sexual health. This study used latent class analysis (LCA) to determine latent constructs of stigma/outness, and used multinomial logistic regression to determine associations with underlying constructs and sexual risk behaviors. RESULTS: Three latent classes emerged: 1) Those who reported low probabilities of stigma (55%; 276/502); 2) Those who reported high probabilities of stigma including physical violence and fear/avoidance of healthcare, and were not "out" (11%; 54/502); and 3) Those who reported high probabilities of stigma including verbal harassment and stigma from family and friends, and were "out" (34%; 172/502). Relative to the "low stigma" class, participants from an urban area (adjusted odds ratio [AOR] = 2.78, 95% Confidence Interval [CI] = 1.53-5.07) and who engaged in condomless anal sex (AOR = 1.85, 95% CI = 1.17-2.91) were more likely to belong to the "high stigma, 'out'" class. In contrast, those who had a concurrent male or female partner were more likely to belong to the "high stigma, not 'out'" class AOR = 2.73, 95% CI = 1.05-7.07). Depression was associated with membership in both high-stigma classes (AOR = 3.14, 95% CI = 1.50-6.55 "not out", AOR = 2.42, 95% CI = 1.51-3.87 "out"). CONCLUSIONS: Sexual behavior stigma at a community level is associated with individual-level risk behaviors among MSM and transgender women, and these associations vary by level of outness about sexual practices. Achieving sufficient coverage of evidence-based stigma interventions may be key to realizing the potential impact of HIV prevention and treatment interventions for MSM and transgender women in Eswatini.

Factors associated with isoniazid resistant tuberculosis among human immunodeficiency virus positive patients in Swaziland: a case-control study.

BACKGROUND: Isoniazid resistant tuberculosis is the most prevalent type of resistance in Swaziland and over two-thirds of the isoniazid resistant tuberculosis patients are tuberculosis and human immunodeficiency virus co-infected. The study aimed to determine risk factors associated with isoniazid resistant tuberculosis among human immunodeficiency virus positive patients in Swaziland. METHODS: This was a case-control study conducted in nine healthcare facilities across Swaziland. Cases were patients with isoniazid resistant tuberculosis (including 78 patients with isoniazid mono-resistant tuberculosis, 42 with polydrug-resistant tuberculosis, and 77 with multidrug-resistant tuberculosis). Controls were presumed drug-susceptible tuberculosis patients (n = 203). Multinomial logistic regression was used to determine related factors. RESULTS: The median time lag from diagnosis to tuberculosis treatment initiation was 50 days for isoniazid mono or poly drug-resistant tuberculosis, 17 days for multidrug-resistant tuberculosis compared to 1 day for drug-susceptible tuberculosis patients. History of previous tuberculosis treatment was positively associated with either isoniazid mono or poly drug-resistant tuberculosis (OR = 7.91, 95% CI: 4.14-15.11) and multidrug-resistant tuberculosis (OR = 12.20, 95% CI: 6.07-24.54). Isoniazid mono or poly resistant tuberculosis patients were more likely to be from rural areas (OR = 2.05, 95% CI: 1.23-3.32) and current heavy alcohol drinkers compared to the drug-susceptible tuberculosis group. Multi drug-resistant tuberculosis patients were more likely to be non-adherent to tuberculosis treatment compared to drug-susceptible tuberculosis group (OR = 3.01, 95% CI: 1.56-5.82). CONCLUSION: To prevent and control isoniazid resistant tuberculosis among HIV-positive patients in Swaziland, the tuberculosis program should strengthen the use of rapid diagnostic tests, detect resistance early, promptly initiate supervised tuberculosis treatment and decentralize quality tuberculosis services to the rural areas. Adherence to tuberculosis treatment should be improved.

Experiences from a community advisory Board in the Implementation of early access to ART for all in Eswatini: a qualitative study.

BACKGROUND: Engaging communities in community-based health research is increasingly being adopted in low- and middle-income countries. The use of community advisory boards (CABs) is one method of practicing community involvement in health research. To date, few studies provide in-depth accounts of the strategies that CAB members use to practice community engagement. We assessed the perspectives, experiences and practices of the first local CAB in Eswatini (formerly known as Swaziland), which was implemented as part of the MaxART Early Access to ART for All study. METHODS: Trained Swazi research assistants conducted two focus group discussions and 13 semi-structured interviews with CAB members who had been part of the MaxART study for at least 2.5 years. Interviews explored CAB composition and recruitment, the activities of CAB members, the mechanisms used to engage with communities and the challenges they faced in their role. RESULTS: The MaxART CAB played an active role in the implementation of the Early Access to Art for All study, and activities mainly focused on: (1) promoting ethical conduct, in particular privacy, consent and confidentiality; (2) communication and education, communicating about the study and educating the community on the benefits of HIV testing and early access to HIV treatment; and (3) liaising between the community and the research team. Strategies for interacting with communities were varied and included attending general community meetings, visiting health facilities and visiting public places such as cattle dipping tanks, buses, bars and churches. Differences in the approach to community engagement between CAB members living in the study areas and those residing outside were identified. CONCLUSION: The experiences of the first CAB in Eswatini demonstrate that community engagement using CABs is a valuable mechanism for engaging communities in implementation studies. Considerations that could impact CAB functioning include clearly defining the scope of the CAB, addressing issues of CAB independence, the CAB budget, providing emotional support for CAB members, and providing continuous training and capacity building. These issues should be addressed during the early stages of CAB formation in order to optimize functioning.

Process and Outcomes of a Recursive, Dialogic Member Checking Approach: A Project Ethnography.

There is limited empirical evidence about member checking, a long-standing qualitative research technique for establishing validity. I conducted directed content analysis of ethnographic data detailing the process and outcomes of a "dialogic" member checking approach I implemented in rural Swaziland. It involved 10 participants, checking results about their participation and empowerment as co-researchers in participatory health research. The process involved participants in four recurring stages: thinking independently, hearing findings, appraising findings, and negotiating final representations. It increased the transferability and accuracy ("transactional" validity) of the results by adding richly descriptive data and establishing the extent of participant agreement with my findings. It had emancipatory outcomes ("transformational" validity) including developing critical understandings, influencing the research trajectory to "give voice" to participants, and establishing more equitable researcher-researched relationships. Further development, implementation, and appraisal of recursive, dialogic approaches can advance member checking as a technique for enhancing "holistic" validity in qualitative health research.

"I don't want them to know": how stigma creates dilemmas for engagement with Treat-all HIV care for people living with HIV in Eswatini.

"Treat-all" programmes aim to improve clinical outcomes and to reduce HIV transmission through regular HIV testing and immediate offer of antiretroviral therapy (ART) for those diagnosed HIV-positive, irrespective of immunological status and symptoms of disease. Global narratives on the benefits of Treat-all anticipate reduced HIV-related stigma and increased "normalisation" of HIV with Treat-all implementation, whereby HIV is remoulded as a manageable, chronic condition where stigmatising symptoms can be concealed. Drawing on Goffman's stigma work, we aimed to investigate how stigma may influence the engagement of clinically asymptomatic people living with HIV (PLHIV) with Treat-all HIV care in Shiselweni, Eswatini (formerly Swaziland). This longitudinal research comprised 106 interviews conducted from August 2016 to September 2017, including repeated interviews with 30 PLHIV, and one-off interviews with 20 healthcare workers. Data were analysed thematically using NVivo 11, drawing upon principles of grounded theory to generate findings inductively from participants' accounts. Stigma was pervasive within the narratives of PLHIV, framing their engagement with treatment and care. Many asymptomatic PLHIV were motivated to initiate ART in order to maintain a "discreditable" status, by preventing the development of visible and exposing symptoms. However, engagement with treatment and care services could itself be exposing. PLHIV described the ways in which these "invisibilising" benefits and exposing risks of ART were continually assessed and navigated over time. Where the risk of exposure was deemed too great, this could lead to intermittent treatment-taking, and disengagement from care. Addressing HIV related stigma is crucial to the success of Treat-all, and should thus be a core component of HIV responses.

Projected cervical Cancer incidence in Swaziland using three methods and local survey estimates.

BACKGROUND: The scarcity of country data (e.g. a cancer registry) for the burden of cervical cancer (CC) in low-income countries (LCIs) such as Swaziland remains a huge challenge. Such data are critical to inform local decision-making regarding resource allocation [1]. We aimed to estimate likely cervical cancer incidence in Swaziland using three different methodologies (triangulation), to help better inform local policy guidance regarding likely higher "true" burden and increased resource allocation required for treatment, cervical cancer screening and HPV vaccine implementation. METHODS: Three methods were applied to estimate CC incidence, namely: 1) application of age-specific CC incidence rates for Southern African region from GLOBOCAN 2012 extrapolated to the 2014 Swaziland female population; 2) a linear regression based model with transformed age-standardised CC incidence against hr-HPV (with and without HIV as a covariate) prevalence among women with normal cervical cytology; and 3) a mathematical model, using a natural history approach based on parameter estimates from various available literature and local survey estimates. We then triangulated estimates and uncertainty from the three models to estimate the most likely CC incidence rate for Swaziland in 2015. RESULTS: The projected incidence estimates for models 1-3 were 69.4 (95% CI: 66.7-72.1), 62.6 per 100,000 (95%CI: 53.7-71.8) and 44.6 per 100,000 (41.5 to 52.1) respectively. Model 2 with HIV prevalence as covariate estimated a higher CC incidence rate estimate of 101.1 per 100,000 (95%CI: 90.3-112.2). The triangulated ('averaged') age-standardized CC incidence based across the 3 models for 2015 was estimated at 69.4 per 100,000 (95% CI: 63.0-77.1) in Swaziland. CONCLUSION: It is widely accepted that cancer incidence (and in this case CC) is underestimated in settings with poor and lacking registry data. Our findings suggest that the projected burden of CC is higher than that suggested from other sources. Local health policy decisions and decision-makers need to re-assess resource allocation to prevent and treat CC effectively, which is likely to persist given the very high burden of hr-HPV within the country.

Marginalization and social change processes among lesbian, gay, bisexual and transgender persons in Swaziland: implications for HIV prevention.

Swaziland has among the highest national adult HIV prevalence globally. There is limited knowledge of HIV vulnerabilities and prevention engagement among lesbian, gay, bisexual and transgender (LGBT) persons in the context of Swaziland's criminalization of consensual same-sex practices. This study explored social processes of marginalization to assess how they could potentiate HIV vulnerabilities and limit engagement in HIV prevention services. Additionally, we assessed positive change to better understand existing strategies employed by LGBT persons to challenge these HIV prevention barriers. Guided by community-based research methodology and conducted in Mbabane and Manzini, Swaziland, data were collected by LGBT peer-research assistants (PRA) in collaboration with an LGBT community organization in Manzini. Semi-structured interviews were conducted by trained PRAs and explored HIV prevention, including experiences of stigma and coping. Audio files were transcribed verbatim, translated to English, and analyzed using thematic techniques. Among participants (n = 51; mean age: 26.47, SD: 4.68), 40 self-identifed as gay or lesbian (78.4%), 11 bisexual (22.6%), and 12 (23.5%) identified as transgender. Findings highlighted three primary processes of marginalization and positive change in structural, community, and internal domains. First, structural marginalization, which included criminalization, healthcare discrimination, and a scarcity of LGBT tailored HIV prevention resources was challenged by grassroots networks created to access and share specific HIV resources with LGBT persons and the Ministry of Health. Second, community marginalization included stigma and multi-dimensional forms of violence, however, this was met with LGBT persons providing mutual peer support, including for accessing HIV testing services. Thirdly, internal marginalization comprised of self-stigma and associated sexual risk practices was contrasted with coping strategies focused on self-acceptance, stemming from social support and leading to healthcare utilization. Jointly, these findings can inform the implementation of community-based and rights affirming HIV prevention and care cascade strategies that improve coverage of services with LGBT persons in Swaziland.

Field suitability and diagnostic accuracy of the Biocentric® open real-time PCR platform for plasma-based HIV viral load quantification in Swaziland.

BACKGROUND: Viral load (VL) testing is being scaled up in resource-limited settings. However, not all commercially available VL testing methods have been evaluated under field conditions. This study is one of a few to evaluate the Biocentric platform for VL quantification in routine practice in Sub-Saharan Africa. METHODS: Venous blood specimens were obtained from patients eligible for VL testing at two health facilities in Swaziland from October 2016 to March 2017. Samples were centrifuged at two laboratories (LAB-1, LAB-2) to obtain paired plasma specimens for VL quantification with the national reference method and on the Biocentric platform. Agreement (correlation, Bland-Altman) and accuracy (sensitivity, specificity) indicators were calculated at the VL thresholds of 416 (2.62 log10) and 1000 (3.0 log10) copies/mL. Leftover samples from patients with discordant VL results were re-quantified and accuracy indicators recalculated. Logistic regression was used to compare laboratory performance. RESULTS: A total of 364 paired plasma samples (LAB-1: n = 198; LAB-2: n = 166) were successfully tested using both methods. The correlation was high (R = 0.82, p < 0.01), and the Bland-Altman analysis showed a minimal mean difference (- 0.03 log10 copies/mL; 95% CI: -1.15 to 1.08). At the clinical threshold level of 3.0 log10 copies/mL, the sensitivity was 88.6% (95% CI: 78.7 to 94.9) and the specificity was 98.3% (95% CI: 96.1 to 99.4). Sensitivity was higher in LAB-1 (100%; 95% CI: 71.5 to 100) than in LAB-2 (86.4%; 95% CI: 75.0 to 94.0). Most upward (n = 8, 2.2%) and downward (n = 11, 3.0%) misclassifications occurred at the 2.62 log threshold, with LAB-2 having a 16 (95% CI: 2.26 to 113.27; p = 0.006) times higher odds of downward misclassification. After retesting of discordant leftover samples (n = 17), overall sensitivity increased to 93.5% (95% CI: 85.5 to 97.9) and 97.1% (95% CI: 90.1 to 99.7) at the 2.62 and 3.0 thresholds, and specificity increased to 98.6% (95% CI: 96.5 to 99.6) and 99.0% (95% CI: 97.0 to 99.8) respectively. CONCLUSIONS: The test characteristics of the Biocentric platform were overall comparable to the national reference method for VL quantification. One laboratory tended to misclassify VL results downwards, likely owing to unmet training needs and lack of previous hands-on practice.
