RESUMO

PURPOSE OF REVIEW: The objective of this study was to describe the increasing incidence and risk of cardiovascular disease among persons living with HIV (PLWH) in Sub-Saharan Africa. We also used data to compare hypertension (a common NCD among PLWH) outcomes between PLWH and HIV-uninfected individuals among older adults in Northwestern Tanzania. RECENT FINDINGS: Hypertension is increasingly common in Sub-Saharan Africa and a leading cause of cardiovascular disease for PLWH. Among those with hypertension, PLWH have a 50% higher risk of incident myocardial infarction compared to the general population. In response to the rising incidence of these non-communicable diseases (NCDs) among PLWH, recently, the Joint United Nations Program on HIV/AIDS supported the integration of NCD care into routine clinical care for HIV. However, data are lacking on levels of awareness of hypertension status, diagnosis, and antihypertensive medication adherence. Given the higher likelihood of elevated blood pressure among PLWH, there is an urgent need to implement interventions to improve blood pressure control in this population. Researchers should evaluate treatment barriers at multiple levels including health system, healthcare providers, and patients' level and tailor evidence-based interventions to increase achievement of blood pressure control for PLWH.

RESUMO

BACKGROUND: Hypertension and Diabetes mellitus are risk factors for cardiovascular diseases that cause 17 million deaths globally. Many of these deaths could have been prevented if hypertensive and diabetic patients had their blood pressure and glucose controlled. Less than 30% of hypertensive and diabetic patients on management have controlled their blood pressure and glucose respectively. This study aimed to determine the preparedness of health facilities in managing hypertensive and diabetic patients in terms of personnel; laboratory services provision, and local use of routinely collected data, and shows differences in preparedness between the levels of facilities. METHODS: We conducted a cross-sectional study in Government, faith-based and private health facilities in two districts in Kilimanjaro region in Tanzania from March to July 2017. We collected data through interviews and observations on the preparedness of the facilities for managing hypertension and DM. RESULTS: Forty-three (43) health facilities and 62 healthcare workers (HCW) participated in the survey. Services for hypertension and DM were available in 37 (86%) and 34 (79%) health facilities respectively. Eighteen (53%) and five (15%) facilities had HCW trained on hypertension and DM management respectively within two years preceding the survey. Regular adherence to treatment guideline was reported in 18 (53%) of the health facilities. More than third of health facilities were without basic equipment for managing hypertension and DM. All the recommended laboratory tests were only available in four (15%) hospitals and one health center. Valid first line medicines for both hypertension and DM were available in six (50%) health centers, four (24%) dispensaries and in four (80.0%) hospitals. Health data collection, analysis and local use for planning were reported in all hospitals, nine (75%) health centers and four (24%) dispensaries. CONCLUSIONS: Health facilities are not fully prepared to manage hypertension and DM. Health centers and dispensaries are mostly affected levels of health facilities. Government interventions to improve facility factors and collaborative approaches to build capacity to HCW are needed to enable health facilities be responsive to these diseases.

RESUMO

BACKGROUND: Despite the increased availability of anti-retroviral therapy, in-hospital HIV mortality remains high in sub-Saharan Africa. Reports from Senegal, Malawi, and Tanzania show rates of in-hospital, HIV-related mortality ranging from 24.2% to 44%. This mixed methods review explored the potential causes of preventable in-hospital mortality associated with HIV infections in sub-Saharan Africa in the anti-retroviral era. RESULTS: Based on our experience as healthcare providers in Africa and a review of the literature we identified 5 health systems failures which may cause preventable in-hospital mortality, including: 1) late presentation of HIV cases, 2) low rates of in-hospital HIV testing, 3) poor laboratory capacity which limits CD4 T-cell testing and the diagnosis of opportunistic infections, 4) delay in initiation of anti-retroviral therapy in-hospital, and 5) problems associated with loss to follow-up upon discharge from hospital. CONCLUSION: Our findings, together with the current available literature, should be used to develop practical interventions that can be implemented to reduce in-hospital mortality.

RESUMO

Background: Heart failure (HF) is a chronic progressive condition in which the heart is unable to pump enough blood to meet the body's need for blood and oxygen. Globally, about 64 million people are affected with HF. This study was undertaken to determine the magnitude and factors associated with potassium abnormalities in heart failure patients on diuretics in Tanzania. Methods: This was a hospital based cross-sectional study conducted at Bugando Medical Centre's outpatient clinic. The selection of this hospital was driven by the significant presence of heart failure patients in the facility and the convenience for the researchers, who were stationed at this facility during the study period. All consenting adult patients aged 18 years and above that were attending the cardiac clinic and had met Framingham criteria for heart failure and were taking diuretics for at least one month were included. Results: The prevalence of hypokalemia and hyperkalemia was found to be 4.3% And 19.3% respectively. The median (IQR) age was 61 (46-70) years and majority of them (52.8%) were females. most of the patients (87.7%) had New York Heart Association (NYHA) class III heart failure. Conclusion: Factors associated with potassium abnormalities include medication use, kidney disease and more severe heart failure. Healthcare providers should ensure that all patients with these associated factors receive regular electrolyte testing. Electrolytes should be part of the baseline investigation to all patients with heart failure starting treatment, and should be closely monitored in every clinic visit for early detection of these abnormalities and possible intervention, including dose adjustments.

RESUMO

Plasmodium spp. infections and cases of malaria are a long-standing public health problem for children living in middle- and low-income countries. Dengue virus causes an emerging under-recognized disease burden. A cross sectional study was conducted between March 2020 and December 2021 to determine the status of malaria and dengue fever, and the associated factors in children living in Mwanza, Tanzania. Clinical features were recorded; blood samples were analyzed using dengue NS1 rapid diagnostics test (NS1-RDT), malaria rapid diagnostic test (MRDT) and PCR and microscopy for malaria parasites. Descriptive analysis was based on infection status; odds ratio and confidence interval were used to determine the factors associated with dengue fever and malaria. The prevalence of malaria in the 436 children included in the final analysis was 15.6%, 8.5%, and 12.1% as determined by MRDT, blood smear examination and PCR, respectively. The prevalence of dengue fever determined by the NS1-RDT was 7.8%. Body rash, muscle and joint/bone pain were associated with a positive rapid dengue test result. Retro-orbital pain characterized Plasmodium spp. and dengue virus co-infections. Clinical signs and symptoms could not readily differentiate between malaria and dengue fever patients or patients co-infected with both causative agents underscoring the urgent need for the accurate laboratory diagnostics. Additional large-scale studies are required to assess the epidemiological burden of acute febrile illness in developing countries and to produce data that will guide empirical treatment.

RESUMO

BACKGROUND: The burden of healthcare associated infections (HCAIs) in low- and middle-income countries (LMICs) remains underestimated due to diagnostic complexity and lack of quality surveillance systems. We designed this study to determine clinical diagnosis, laboratory-confirmed, associated factors and risks of HCAIs. METHODS: This hospital-based longitudinal cohort study was conducted between March and June 2022 among adults (≥ 18 years) admitted in medical wards at BMC in Mwanza, Tanzania. Patients who were negative for HCAIs by clinical evaluations and laboratory investigations during admission were enrolled and followed-up until discharge or death. Clinical samples were collected from patients with clinical diagnosis of HCAIs for conventional culture and antimicrobial sensitivity testing. RESULTS: A total of 350 adult patients with a median [IQR] age of 54 [38-68] years were enrolled in the study. Males accounted for 54.6% (n = 191). The prevalence of clinically diagnosed HCAIs was 8.6% (30/350) of which 26.7% (8/30) had laboratory-confirmed HCAIs by a positive culture. Central-line-associated bloodstream infection (43.3%; 13/30) and catheter-associated urinary tract infection (36.7%; 11/30) were the most common HCAIs. Older age was the only factor associated with development of HCAIs [mean (± SD); [95%CI]: 58.9(± 12.5); [54.2-63.5] vs. 51.5(± 19.1); [49.4-53.6] years; p = 0.0391) and HCAIs increased the length of hospital stay [mean (± SD); [95%CI]: 13.8 (± 3.4); [12.5-15.1] vs. 4.5 (± 1.7); [4.3-4.7] days; p < 0.0001]. CONCLUSION: We observed a low prevalence of HCAIs among adult patients admitted to medical wards in our setting. Central-line-associated bloodstream infections and catheter-associated urinary tract infections are common HCAIs. Significantly, older patients are at higher risk of acquiring HCAIs as well as patients with HCAIs had long duration of hospital stays.

RESUMO

BACKGROUND: Worldwide, people with hypertensive urgency experience high rates of hospitalization and death due to medication non-adherence. Interventions to improve medication adherence and health outcomes after hypertensive urgency are urgently needed. METHODS: This prospective cohort assessed the effect of a peer counselor intervention-named Rafiki mwenye msaada-on the 1-year incidence of hospitalization and/or death among adults with hypertensive urgency in Mwanza, Tanzania. We enrolled 50 patients who presented with hypertensive urgency to 2 hospitals in Mwanza, Tanzania. All 50 patients received a Rafiki mwenye msaada an individual-level, time-limited case management intervention. Rafiki mwenye msaada aims to empower adult patients with hypertensive urgency to manage their high blood pressure. It consists of 5 sessions delivered over 3 months by a peer counselor. Outcomes were compared to historical controls. RESULTS: Of the 50 patients (median age, 61 years), 34 (68%) were female, and 19 (38%) were overweight. In comparison to the historical controls, the intervention cohort had a significantly lower proportion of patients with a secondary level of education (22% vs. 35%) and health insurance (40% vs. 87%). Nonetheless, the 1-year cumulative incidence of hospitalization and/or death was 18% in the intervention cohort vs. 35% in the control cohort (adjusted Hazard Ratio, 0.48, 95% CI 0.24-0.97; P = 0.041). Compared to historical controls, intervention participants maintained higher rates of medication use and clinic attendance at both 3- and 6-months but not at 12 months. Of intervention participants who survived and remained in follow-up, >90% reported good medication adherence at all follow-up time points. CONCLUSION: Our findings support the hypothesis that a peer counselor intervention may improve health outcomes among adults living with hypertensive urgency. A randomized clinical trial is needed to evaluate the intervention's effectiveness.

RESUMO

BACKGROUND: Stroke is a second leading cause of death globally, with an estimated one in four adults suffering a stroke in their lifetime. We aimed to describe the clinical characteristics, quality of care, and outcomes in adults with stroke in urban Northwestern Tanzania. METHODS: We analyzed de-identified data from a prospective stroke registry from Bugando Medical Centre in Mwanza, the second largest city in Tanzania, between March 2020 and October 2022. This registry included all adults ⩾18 years admitted to our hospital who met the World Health Organization clinical definition of stroke. Information collected included demographics, risk factors, stroke severity using the National Institutes of Health Stroke Scale, brain imaging, indicators for quality of care, discharge modified Rankin Scale, and in-hospital mortality. We examined independent factors associated with mortality using logistic regression. RESULTS: The cohort included 566 adults, of which 52% (294) were female with a mean age of 65 ± 15 years. The majority had a first-ever stroke 88% (498). Premorbid hypertension was present in 86% (488) but only 41% (200) were taking antihypertensive medications before hospital admission; 6% (32) had HIV infection. Ischemic strokes accounted for 66% (371) but only 6% (22) arriving within 4.5 h of symptom onset. In-hospital mortality was 29% (127). Independent factors associated with mortality were severe stroke (adjusted odds ratio (aOR) = 1.81, 95% confidence interval (CI) = 1.47-2.24, p < 0.001), moderate to severe stroke (aOR = 1.49, 95% CI = 1.22-1.84, p < 0.001), moderate stroke (aOR = 1.80, 95% CI = 1.52-2.14, p < 0.001), leukocytosis (aOR = 1.19, 95% CI = 1.03-1.38, p = 0.022), lack of health insurance coverage (aOR = 1.15, 95% CI = 1.02-1.29, p = 0.025), and not receiving any form of venous thromboembolism prophylaxis (aOR = 1.18, 95% CI = 1.02-1.37, p = 0.027). CONCLUSION: We report a stroke cohort with poor in-hospital outcomes in urban Northwestern Tanzania. Early diagnosis and treatment of hypertension could prevent stroke in this region. More work is needed to raise awareness about stroke symptoms and to ensure that people with stroke receive guidelines-directed therapy.

RESUMO

INTRODUCTION: Health insurance coverage is critical for persons living with chronic conditions such as heart failure. Lack of health insurance may affect the ability to access regular healthcare appointments, pay for medication refills which can result in frequent hospitalization that is associated with poor clinical outcomes. In scarce resource locations such as sub-Saharan Africa, where uptake of health insurance is still suboptimal, the effect of health insurance on chronic conditions such as heart failure is poorly understood. The objective of this study was to assess the association of health insurance on the severity of heart failure for patients attending outpatient clinics at tertiary hospitals in Mwanza, Tanzania. METHODS: As part of a larger cohort study, patients with heart failure were recruited from Bugando Medical Center (BMC) and Sekou Toure Regional Hospital (STRH) in Mwanza City, Tanzania. Heart failure was based on Framingham criteria and the severity was determined by New York Heart Association (NYHA) classification. Descriptive analysis and multivariable logistic regression were used to describe the study participants and to assess the association between health insurance status and the severity of heart failure at baseline. RESULTS: 418 patients were enrolled, and majority were female (n = 264, 63%), small scale farmers (n = 278, 66.5%) and were from Mwanza City (n = 299, 71.5%). More than two-thirds of patients did not have health insurance (n = 295, 70.6%) and the majority were in the NYHA I and II classification (n = 267, 64.7%). There was no association between health insurance status and the severity of heart (aOR 0.97; 95% CI 0.84-1.60). Being male, small-scale businessperson and those seen at STRH was associated with higher odds of being in NYHA Class III/IV (aOR = 1.97; 95% CI: 1.21-3.17), (aOR = 2.61; 95% CI: 1.27-5.34) and (aOR 1.91 95% CI: 1.17-3.13) respectively. Having secondary and college education was associated with lower odds of being in Class III/IV (0.42; 95% CI: 0.18-0.98) and (aOR = 0.23 95% CI: 0.06-0.86) respectively. CONCLUSION: In this study, only a third of the patients had health insurance. Health insurance was not associated with the severity of heart failure. Since heart failure is a chronic condition patients who do not have health insurance may incur out of pocket expenses, future research should focus on the effect of out-of-pocket expenditures on clinical outcomes.

RESUMO

BACKGROUND: Hypertensive urgency is associated with a high risk for cardiovascular events and mortality in the United States and Europe, but data from low-income countries and interventions to improve outcomes are lacking. METHODS: We conducted a 1-year prospective study of the prevalence and outcomes of hypertensive urgency (blood pressure (BP) ≥180 mm Hg/120 mm Hg without end-organ damage) in a busy outpatient clinic in Tanzania. RESULTS: Of 7,600 consecutive adult outpatients screened with 3 unattended automated BP measurements according to standard protocol, the prevalence of hypertensive crisis was 199/7,600 (2.6%) (BP ≥180 mm Hg/120 mm Hg) and the prevalence of hypertensive urgency was 164/7,600 (2.2%). Among 150 enrolled patients with hypertensive urgency, median age was 62 years (54-68), 101 (67.3%) were women, and 53 (35%) were either hospitalized or died within 1 year. In a multivariate model, the strongest predictor of hospitalization/death was self-reported medication adherence on a 3 question scale (hazard ratio: 0.06, P < 0.001); 90% of participants with poor adherence were hospitalized or died within 1 year. CONCLUSIONS: Patients with hypertensive urgency in Africa are at high risk of poor outcomes. Clinicians can identify the patients at highest risk for poor outcomes with simple questions related treatment adherence. New interventions are needed to improve medication adherence in patients with hypertensive urgency.

RESUMO

OBJECTIVE: To determine one-year, post-hospital mortality and the predictors of mortality in Tanzanian adults with heart failure (HF) compared to other admitted adults. METHODS: In this prospective cohort study we consecutively enrolled medical inpatients admitted during a 3-month period, screened for HF and followed until 12 months after hospital discharge. Standardized history, physical examination, echocardiography and laboratory investigations were obtained during hospital presentation. The primary outcome was one-year post-discharge mortality. The secondary outcome was in-hospital mortality. Cox regression adjusted for age and sex was used. RESULTS: During the study period, we enrolled 558 adults; 145 had HF and 107 of these survived until discharge. Patients with HF had a higher one-year post-hospital discharge mortality than all other diagnoses (62/107 (57.9%) vs 150/343 (43.7%), respectively, HR=1.57[1.13-2.18]). In-hospital mortality was similar. Markers of renal disease were more common in adults with HF (40/107 (37.4%) and were the strongest independent predictors of post-hospital mortality: low eGFR (HR=2.94[1.62-5.31]) and proteinuria (HR=2.03, [95%CI 1.13-3.66]). No patients discharged with the combination of low eGFR/proteinuria survived to the one-year endpoint. Of note, 79/145 (54.5%) of adults admitted with HF were newly diagnosed during hospital admission. CONCLUSIONS: Over half of adults discharged with HF died within 12months after discharge. Adults with HF had higher post-hospital mortality compared to other medical inpatients. Markers of renal disease were the strongest predictor of this mortality. Innovative interventions are needed to reduce post-hospital mortality in adults with HF and should focus on those with renal disease.

RESUMO

INTRODUCTION: Little is known about hepatotoxicity in patients with schistosome and HIV co-infections. Several studies have reported increased liver enzymes and bilirubin levels associated with schistosome infection. We investigated whether HIV-infected adults on antiretroviral therapy who had S. mansoni co-infection had a higher prevalence of hepatotoxicity than those without. METHODOLOGY/PRINCIPAL FINDINGS: We determined the presence and grade of hepatotoxicity among 305 HIV-infected outpatients who had been on medium-term (3-6 months) and long-term (>36 months) antiretroviral therapy in a region of northwest Tanzania where S. mansoni is hyperendemic. We used the AIDS Clinical Trial Group definition to define mild to moderate hepatotoxicity as alanine aminotransferase, alanine aminotransferase, and/or bilirubin elevations of grade 1 or 2, and severe hepatotoxicity as any elevation of grade 3 or 4. We determined schistosome infection status using the serum circulating cathodic antigen rapid test and used logistic regression to determine factors associated with hepatotoxicity. The prevalence of mild-moderate and severe hepatotoxicity was 29.6% (45/152) and 2.0% (3/152) in patients on medium-term antiretroviral therapy and 19.6% (30/153) and 3.3% (5/153) in the patients on long-term antiretroviral therapy. S. mansoni infection was significantly associated with hepatotoxicity on univariable analysis and after controlling for other factors associated with hepatotoxicity including hepatitis B or C and anti-tuberculosis medication use (adjusted odds ratio = 3.0 [1.6-5.8], p = 0.001). CONCLUSIONS/SIGNIFICANCE: Our work demonstrates a strong association between S. mansoni infection and hepatotoxicity among HIV-infected patients on antiretroviral therapy. Our study highlights the importance of schistosome screening and treatment for patients starting antiretroviral therapy in schistosome-endemic settings. Additional studies to determine the effects of schistosome-HIV co-infections are warranted.

RESUMO

Although target point-of-care (POC) ultrasonography has been shown to benefit patients in resource-limited settings, it is not clear whether a systematic POC ultrasound assessment in these settings can also lead to similar changes in patient management. A predefined systematic set of POC ultrasound scans were performed on inpatients at a tertiary referral hospital in Tanzania to see if this resulted in changes to patient management. Of the 55 patients scanned, an abnormality was detected in 75% (N = 41), and a change in patient management was recommended or implemented on the basis of POC ultrasound findings in 53% (N = 29). The main impact was earlier initiation of treatment due to more rapid and accurate diagnosis. Further research is warranted to determine whether systematic POC ultrasonography would result in improved patient outcomes in resource-limited settings.

RESUMO

INTRODUCTION: Little is known about outcomes after hospitalization for HIV-infected adults in sub-Saharan Africa. We determined 12-month, posthospital mortality rates in HIV-infected vs. uninfected adults and predictors of mortality. METHODS: In this prospective cohort study, we enrolled adults admitted to the medical wards of a public hospital in northwestern Tanzania. We conducted standardized questionnaires, physical examinations, and basic laboratory analyses including HIV testing. Participants or proxies were called at 1, 3, 6, and 12 months to determine outcomes. Predictors of in-hospital and posthospital mortality were determined using logistic regression. Cox regression models were used to analyze mortality incidence and associated factors. To confirm our findings, we studied adults admitted to another government hospital. RESULTS: We enrolled 637 consecutive adult medical inpatients: 38/143 (26.6%) of the HIV-infected adults died in hospital vs. 104/494 (21.1%) of the HIV-uninfected adults. Twelve-month outcomes were determined for 98/105 (93.3%) vs. 352/390 (90.3%) discharged adults, respectively. Posthospital mortality was 53/105 (50.5%) for HIV-infected adults vs. 126/390 (32.3%) for HIV-uninfected adults (adjusted P = 0.006). The 66/105 (62.9%) HIV-infected adults who attended clinic within 1 month after discharge had significantly lower mortality than the other HIV-infected adults [adjusted hazards ratio = 0.17 (0.07-0.39), P < 0.001]. Adults admitted to a nearby government hospital had similar high rates of posthospital mortality. CONCLUSIONS: Posthospital mortality is disturbingly high among HIV-infected adult inpatients in Tanzania. The posthospital period may offer a window of opportunity to improve survival in this population. Interventions are urgently needed and should focus on increasing posthospital linkage to primary HIV care.

RESUMO

SETTING: Clinical trials have shown that early initiation of antiretroviral therapy in HIV-infected patients with tuberculosis saves lives, but models for implementation of this new strategy have been under-studied in real-world settings. OBJECTIVE: To identify the barriers and possible solutions for implementing concurrent early treatment with antiretroviral and anti-tuberculosis therapy in a large East African referral hospital where the prevalence of both infections is high. DESIGN: In-depth interviews among hospital administrators, laboratory technicians, nurses, pharmacists, and physicians. RESULTS: Twenty-six hospital staff identified six key barriers and corresponding solutions to promote rapid initiation of antiretroviral therapy in HIV-infected inpatients with tuberculosis. These include revising systems of medication delivery, integrating care between inpatient and outpatient systems, training hospital nurses to counsel and initiate medications in inpatients, and cultivating a team approach to consistent guideline implementation. CONCLUSION: Most barriers identified by hospital staff were easily surmountable with reorganization, training, and policy changes at minimal cost. Efforts to reduce mortality for HIV and tuberculosis co-infected patients in accordance with new World Health Organization guidelines are currently hampered by implementation barriers in real-world settings. Our findings suggest that these can be overcome with strategic enactment of simple, realistic interventions to promote early dual treatment for HIV/tuberculosis co-infected patients.

RESUMO

BACKGROUND: Cryptococcal meningitis is a leading cause of death among HIV-infected individuals in sub-Saharan Africa. Recent developments include the availability of intravenous fluconazole, cryptococcal antigen assays and new data to support fluconazole pre-emptive treatment. In this study, we describe the impact of screening HIV-positive adult inpatients with serum cryptococcal antigen (CRAG) at a Tanzanian referral hospital. METHODS: All adults admitted to the medical ward of Bugando Medical Centre are counseled and tested for HIV. In this prospective cohort study, we consecutively enrolled HIV-positive patients admitted between September 2009 and January 2010. All patients were interviewed, examined and screened with serum CRAG. Patients with positive serum CRAG or signs of meningitis underwent lumbar puncture. Patients were managed according to standard World Health Organization treatment guidelines. Discharge diagnoses and in-hospital mortality were recorded. RESULTS: Of 333 HIV-infected adults enrolled in our study, 15 (4.4%) had confirmed cryptococcal meningitis and 10 of these 15 (66%) died. All patients with cryptococcal meningitis had at least two of four classic symptoms and signs of meningitis: fever, headache, neck stiffness and altered mental status. Cryptococcal meningitis accounted for a quarter of all in-hospital deaths. CONCLUSIONS: Despite screening of all HIV-positive adult inpatients with the serum CRAG at the time of admission and prompt treatment with high-dose intravenous fluconazole in those with confirmed cryptococcal meningitis, the in-hospital mortality rate remained unacceptably high. Improved strategies for earlier diagnosis and treatment of HIV, implementation of fluconazole pre-emptive treatment for high-risk patients and acquisition of better resources for treatment of cryptococcal meningitis are needed.
