Prevalence and Risk Factors for Renal Insufficiency among Adults Living with HIV in Tanzania: Results from a Cross-Sectional Study in 2020-2021.

With improved survival, adults living with HIV (ALHIV) are increasingly likely to experience age-related and HIV-related comorbidities, including renal insufficiency. Other risk factors for renal insufficiency (high blood pressure (BP), obesity, diabetes, and dyslipidemia) are also growing more common among ALHIV. To determine the prevalence of renal insufficiency (defined as an eGFR < 60 mL/min/1.73 m2) and factors associated with reduced eGFR, we conducted a cross-sectional study at six HIV clinics in Dar-es-Salaam, Tanzania. We applied multivariable (MV) ordinal logistic regression models to identify factors associated with reduced eGFR and examined the interaction of age with BP levels. Among the 450 ALHIV on ART analyzed [26% males; median age 43 (IQR: 18-72) years; 89% on tenofovir-containing ART; 88% HIV viral load ≤50 copies/mL], 34 (7.5%) had renal insufficiency. Prevalence was higher among males (12%) vs. females (6%), p = 0.03; ALHIV ≥50 (21%) vs. <50 years (2.5%), p < 0.001; those with high [≥130/80 mmHg (15%)] vs. normal [<120/80 mmHg (4%)] BP, p < 0.01 and those with dyslipidemia (10%) vs. those without (4.5%), p < 0.03. After adjusting for covariates, age (in years) was the only covariate with a statistically significant association with reduced eGFR (OR = 1.09 (1.07-1.12), p < 0.001). No significant interaction between age and BP was found. Interventions to increase routine screening for renal insufficiency, especially among older ALHIV, and improve BP control are critical to reducing kidney disease-related morbidity and mortality.

"I only seek treatment when I am ill": experiences of hypertension and diabetes care among adults living with HIV in urban Tanzania.

BACKGROUND: For adults living with HIV (ALHIV) and comorbidities, access to comprehensive healthcare services is crucial to achieving optimal health outcomes. This study aims to describe lived experiences, challenges, and coping strategies for accessing care for hypertension and/or diabetes (HTN/DM) in HIV care and treatment clinics (CTCs) and other healthcare settings. METHODOLOGY: We conducted a qualitative study that employed a phenomenological approach between January and April 2022 using a semi-structured interview guide in six HIV CTCs in Dar es Salaam, Tanzania. We purposively recruited 33 ALHIV with HTN (n = 16), DM (n = 10), and both (n = 7). Thematic content analysis was guided by the 5As framework of access to care. FINDINGS: The majority of the participants were females, between the ages of 54-73, and were recruited from regional referral hospitals. HIV CTCs at regional referral hospitals had more consistent provision of HTN screening services compared to those from district hospitals and health centers. Participants sought HTN/DM care at non-CTC health facilities due to the limited availability of such services at HIV CTCs. However, healthcare delivery for these conditions was perceived as unaccommodating and poorly coordinated. The need to attend multiple clinic appointments for the management of HTN/DM in addition to HIV care was perceived as frustrating, time-consuming, and financially burdensome. High costs of care and transportation, limited understanding of comorbidities, and the perceived complexity of HTN/DM care contributed to HTN/DM treatment discontinuity. As a means of coping, participants frequently monitored their own HTN/DM symptoms at home and utilized community pharmacies and dispensaries near their residences to check blood pressure and sugar levels and obtain medications. Participants expressed a preference for non-pharmaceutical approaches to comorbidity management such as lifestyle modification (preferred by young participants) and herbal therapies (preferred by older participants) because of concerns about side effects and perceived ineffectiveness of HTN/DM medications. Participants also preferred integrated care and focused patient education on multimorbidity management at HIV CTCs. CONCLUSION: Our findings highlight significant barriers to accessing HTN/DM care among ALHIV, mostly related to affordability, availability, and accessibility. Integration of NCD care into HIV CTCs, could greatly improve ALHIV health access and outcomes and align with patient preference.

High Prevalence of Sexually Transmitted and Reproductive Tract Infections (STI/RTIs) among Patients Attending STI/Outpatient Department Clinics in Tanzania.

We determined the prevalence and reported risk factors associated with sexually transmitted and reproductive tract infections (STI/RTIs) among patients who presented with genital symptoms in STI/outpatient department (OPD) clinics in two regional referral hospitals and six health centres in six regions in Tanzania. Methods: The patients were consecutively recruited, and the data collection was conducted in eight health care facilities from 2014 to 2016. Genital swabs were collected for the detection of the aetiological pathogens of STI/RTIs. Results: A total of 1243 participants were recruited in the study; the majority (1073, 86%) were women. The overall median age was 27.8. The prevalence of Neisseria gonorrhoeae was 25.7% (319/1243), with proportions of 50.9 and 21.5% for men and women, respectively, of Chlamydia trachomatis 12.9% (160/1241) and Mycoplasma genitalium 4.7% (53/1134). Unmarried men were more often likely to be infected with gonococcal infections as compared to their women counterparts (57.9 vs. 24.1%) p < 0.001. The majority presented with genital discharge syndrome (GDS) 93.6% (1163/1243), genital ulcer disease (GUD) 13.0% (162/1243) and GDS + GUD 9.6% (119/1243). GDS was more common in the health centres, 96.1% (1195/1243), vs. the regional referral hospitals, 92.2% (1146/1243) (p = 0.01), but those reported to the regional referral hospitals were more likely to be infected with N. gonorrhoeae (OR = 2.5) and C. trachomatis (OR = 2.1) than those from the health centres (p < 0.001). The prevalence of bacterial vaginosis (BV) and vaginal candidiasis (VC) was 24.1 and 10.4%, respectively. Interestingly, unmarried and BV-positive women were less likely to be infected with VC (p = 0.03), though VC was strongly inversely associated with an N. gonorrhoeae infection (p < 0.001). High proportions of N. gonorrhoeae (51.1%) and C. trachomatis (23.3%) were found in the Dodoma and Dar es Salaam regions, respectively. M. genitalium (7.6%) was found to be the highest in Mwanza. Conclusion: We reported a high prevalence of STI/RTIs. The findings suggest that these infections are common and prevalent in STI/OPD clinics in six regions of Tanzania. We recommend surveillance to be conducted regularly to elucidate the true burden of emerging and classical STI/RTIs by employing modern and advanced laboratory techniques for the detection and monitoring of STI/RTIs in low- and high-risk populations, including the community settings.

Ideal Cardiovascular Health: Distribution, Determinants and Relationship with Health Status among People Living with HIV in Urban Tanzania.

Background: Ageing adults living with HIV (ALHIV) have increased risk of cardiovascular diseases as a result of HIV-infection-related chronic immune activation and inflammatory responses. Cardiovascular health index (CVHI) is a valid and relatively simple index for assessing the cardiovascular health (CVH) of the general population. Use of this index among ALHIV in Sub Saharan Africa, a resource-restricted setting where it could be mostly beneficial, remains limited. Understanding of the distribution and associated factors may inform the design of optimal interventions to improve CVH of ALHIV. Objective: We aimed to assess the distribution and factors associated with CVHI scores among ALHIV in an urban setting in Tanzania. Methods: A cross-sectional study was conducted among ALHIV on antiretroviral therapy at six HIV clinics in Dar-es-Salaam, Tanzania. We summed the score of each of the seven CVHI metric to obtain the overall CVHI score and assessed the distribution of the score by sex. We then categorized the overall score into ideal (5-7), intermediate (3-4) and poor (<3) CVH categories and performed ordinal regression to identify CVHI score associated factors. Results: In all, 629 ALHIV [mean age of 43.5(SD ± 11.2) years] were enrolled. Most had ideal levels of blood glucose (96.2%) and smoking status (83.4%) while less than half had ideal BMI (48.1%), blood pressure (BP) (43.9%) and dietary intake (7.8%). Less than half (47.6%) showed ideal CVH, while less than 1% had all seven metrics at ideal level. Older age (0.96(95%CI:0.95-0.97), p-value < 0.001), being retired/unemployed (0.59(95%CI:0.43-0.81), p-value < 0.01), being employed (0.76(95%CI:0.62-0.94), p-value = 0.01) alcohol use (0.41(95%CI:0.21-0.80), p-value = 0.01) and presence of non-communicable disease comorbidities (0.68(95%CI:0.48-0.97), p-value = 0.04) had significant lower odds of ideal CVH. Conclusion: Based on our findings, interventions to improve CVH of ALHIV should target BP management, health education on diet for BMI control and reduction in alcohol consumption, particularly among ageing ALHIV with comorbidities.

Antimicrobial Susceptibility Testing Patterns of Neisseria gonorrhoeae from Patients Attending Sexually Transmitted Infections Clinics in Six Regions in Tanzania.

Antimicrobial resistance (AMR) is global health threat that is on the increase, and it has been adversely affecting the proper management of sexually transmitted infections (STI). Data on antimicrobial susceptibility testing patterns of N. gonorrhoeae are limited in local settings. We determined in vitro antimicrobial susceptibility and phenotypic profiles of N. gonorrhoeae isolated from STI/Outpatient Department (OPD) clinics. Minimum Inhibitory Concentrations (MIC) (µg/mL) were determined using E-Test and agar dilution methods for previously and currently recommended antimicrobial agents. A total of 164 N. gonorrhoeae isolates from urethral discharge and endocervical swabs were tested. The prevalence of resistant N. gonorrhoeae to tetracycline, norfloxacin, penicillin and ciprofloxacin were 98.6%, 82.2%, 84.3% and 75.6%, respectively. None of the isolates was resistant to kanamycin. Penicillinase producing N. gonorrhoeae (PPNG) was found to be 73.7%, with 56.7% and 43.3% observed among isolates from women and men, respectively. Tetracycline resistant-N. gonorrhoeae (TRNG) was found to be 34.0%, and QRNG with HLR to ciprofloxacin was 79.9%. The overall MDR-NG was 79.9%, and XDR-NG was 3.6%. MIC50 and MIC90 were 4.0 and 8.0 and 2.0 and 4.0 µg/mL for ciprofloxacin and norfloxacin, respectively. Dendrograms showed that 44 phenotypic groups are associated with a high rate of AMR among high MDR-NG and moderate XDR-NG isolates. The predominant groups of quinolone-resistant N. gonorrhoeae (QRNG)+PPNG (34.7%) and QRNG+PPNG+TRNG (32.9%) were observed among the isolates having HLR to ciprofloxacin. We reported a high prevalence of AMR (>90%) to previously recommended antimicrobials used for the treatment of gonorrhoea. Multidrug resistant N. gonorrhoeae (MDR-NG) was highly reported, and extensively drug resistant (XDR-NG) has gradually increased to the currently recommended cephalosporins including ceftriaxone and cefixime. Heterogeneous groups of QRNG+PPNG+ and QRNG+PPNG+TRNG were highly resistant to penicillin, tetracycline, ciprofloxacin and norfloxacin. A surveillance program is imperative in the country to curb the spread of AMR.

Persons living with HIV infection on antiretroviral therapy also consulting traditional healers: a study in three African countries.

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.

Incomplete adherence among treatment-experienced adults on antiretroviral therapy in Tanzania, Uganda and Zambia.

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.
