RESUMO

BACKGROUND: Sub-Saharan African countries have a high burden of viral hepatitis and poor access to screening and care. The aim of this study was to evaluate the feasibility and acceptability of using the plasma separation card (PSC) for viral hepatitis B and C screening among people living with HIV (PLHIV) in Cameroon and Uganda. METHODS: This is a cross-sectional study carried out between 05/2021 and 03/2023 including 192 PLHIV in Cameroon (n = 104) and Uganda (n = 88). Basic sociodemographic variables and whole blood samples were collected. Adequate filling with blood of PSCs was used to determine feasibility together with participant responses to questions on acceptability. A logistic regression model was carried out to assess the relationship between PSC acceptability and factors of interest. RESULTS: 70% of participants reported PSC as an acceptable viral hepatitis screening tool, and it was significantly more accepted in Uganda than Cameroon (100% vs. 43.2%, p < 0.001). Similarly, 75% of PSCs had at least one spot sample filled and were viable for analysis, 99% were correctly filled in Uganda and 53.4% in Cameroon. Reported ease of method performance (aOR: 24.77 95% CI 2.97-206.42, p = 0.003) and reduced collection time (aOR: 3.73 95% CI 1.26-11.04, p = 0.017) were associated with greater odds of PSC acceptance. HBsAg + and anti-HCV + prevalence were 11.1% and 1.0%, respectively. CONCLUSIONS: In spite of country differences, overall, the PSC was reported as a feasible and acceptable viral hepatitis testing method. Acceptability and feasibility of the method must be explored in heterogeneous target communities and qualitative research to better understand country-specific barriers and facilitators should be carried out.

RESUMO

Background: There was no data on the prevalence of Gastrointestinal bleeding (GI) among patients admitted on the emergency ward at Mulago hospital. This was partly because the medical records were not adequately completed as designed. Objective: To estimate the prevalence of gastrointestinal bleeding and the frequency of selected predictors of mortality on the emergency ward. Methods: This was a chart review incorporating quality improvement methods in the process of data collection. The health care team was educated on documentation of gastrointestinal bleeding while being assessed weekly for knowledge and practice of completion of the Casualty Assessment form (CAF) from which a documented diagnosis of GI bleeding and selected predictors of mortality were looked for. Results: Of the 1881 CAF assessed, 278 had a documented diagnosis of GI bleeding, resulting in a prevalence of 6.8%. Of the patients with GI bleeding, 14.1% had age greater than 60 years, 24.0% had a systolic blood pressure less than 100mmHg and 44.5% had a heart rate greater than 100 beats per minute. Conclusion: The prevalence of GI bleeding on the medical emergency ward of Mulago hospital is high. This calls for strategies for resuscitative management of this life-threatening medical emergency. Among the selected predictors of mortality, tachycardia was most frequent followed by hypotension. These should always be assessed in a patient with GI bleeding and resuscitative measures with blood transfusion and intravenous fluids undertaken to correct them.

RESUMO

Prevention of mother-to-child transmission of hepatitis B virus (HBV) infection is a cornerstone of efforts to support progress towards elimination of viral hepatitis. Current guidelines recommend maternal screening, antiviral therapy during the third trimester of high-risk pregnancies, universal and timely HBV birth dose vaccination, and post-exposure prophylaxis with hepatitis B immunoglobulin for selected neonates. However, serological and molecular diagnostic testing, treatment and HBV vaccination are not consistently deployed, particularly in many high endemicity settings, and models predict that global targets for reduction in paediatric incidence will not be met by 2030. In this article, we briefly summarise the evidence for current practice and use this as a basis to discuss areas in which prevention of mother-to-child transmission can potentially be enhanced. By reducing health inequities, enhancing pragmatic use of resources, filling data gaps, developing advocacy and education, and seeking consistent investment from multilateral agencies, significant advances can be made to further reduce vertical transmission events, with wide health, societal and economic benefits.

RESUMO

COVID-19 has had devastating effects on health systems but reports from sub-Saharan Africa are few. We compared inpatient admissions, diagnostic tests performed, clinical characteristics and inpatient mortality before and during the COVID-19 pandemic at an urban tertiary facility in Uganda. We conducted a retrospective chart review of patients admitted at Kiruddu National Referral Hospital in Uganda between January-July 2019 (before the pandemic) and January-July 2020 (during the pandemic). Of 3749 inpatients, 2014 (53.7%) were female, and 1582 (42.2%) had HIV. There was a 6.1% decline in admissions from 1932 in 2019 to 1817 in 2020. There were significantly fewer diagnostic tests performed in 2020 for malaria, tuberculosis, and diabetes. Overall, 649 (17.3%) patients died. Patients admitted during the COVID-19 pandemic (adjusted odds ratio [aOR] 1.2, 95% confidence interval [CI] 1.04-1.5, p = 0.018), patients aged ≥ 60 years (aOR 1.6, 95% CI 1.2-2.1, p = 0.001), HIV co-infected (aOR 1.5, 95% CI 1.2-1.9, p < 0.001), and those admitted as referrals (aOR 1.5, 95% CI 1.2-1.9, p < 0.001) had higher odds of dying. The COVID-19 pandemic disrupted inpatient service utilization and was associated with inpatient mortality. Policy makers need to build resilience in health systems in Africa to cope with future pandemics.

RESUMO

Measures to contain the Corona Virus Disease 2019 (COVID-19) pandemic curtailed access to prevention and treatment services for endemic infectious diseases like HIV. We used an uncontrolled before-and-after study design to compare general and HIV positive (HIV+) inpatient outcomes at a tertiary hospital in Uganda, using electronic records of medical inpatients. Data was downloaded, cleaned in Microsoft Excel, and exported to STATA for analysis. We determined the difference in number of admissions and median length of hospital stay using Mann-Whitney U test; and difference in median survival and incidence rates of mortality using Kaplan - Meier statistics, between the pre- and peri-COVID-19 groups. Of 7506 patients admitted to Kiruddu NRH, 50.8% (3812) were female and 18.7% (1,401) were aged 31-40 years, and 18.8% (1,411) were HIV+. Overall, 24.6% (1849) died. Total admissions were lower (2192 vs. 5314 patients), overall mortality rate higher (41.8% vs. 17.6%, p < 0.01), median length of hospital stay longer (6 vs. 4 days, p < 0.01) and median survival shorter (11 vs. 20 days, Chi-square = 252.05, p < 0.01) in the peri- than in pre-COVID-19 period. The adjusted hazard ratio (aHR) of death was 2.08 (95% CI: 1.85-2.23, p < 0.01) in the peri- compared to the pre-COVID-19 period. These differences were more pronounced in HIV + patients. Compared to pre-COVID-19, the peri-COVID-19 period registered lower inpatient admissions but poorer treatment outcomes for general and HIV + inpatients. Emerging epidemic responses should minimize disruption to inpatient care, especially for HIV + individuals.

RESUMO

BACKGROUND: Despite facing a dual burden of HBV and HIV, Africa lacks experience in offering integrated care for HIV and HBV. To contextualize individual and group-level feasibility and acceptability of an integrated HIV/HBV care model, we explored perspectives of health care providers and care recipients on feasibility and acceptability of integration. METHODS: In two regional hospitals of West Nile region, we performed a demonstration project to assess feasibility and acceptability of merging the care of HBV-monoinfected patients with existing HIV care system. Using interviews with health care providers as key informants, and 6 focus groups discussions with 3 groups of patients, we explored feasibility [(i)whether integration is perceived to fit within the existing healthcare infrastructure, (ii) perceived ease of implementation of HIV/HBV integrated care, and (iii) perceived sustainability of integration] and acceptability [whether the HIV/HBV care model is perceived as (i) suitable, (ii) satisfying and attractive (iii) there is perceived demand, need and intention to recommend its use]. We audio-recorded the interviews and data was analysed using framework analysis. RESULTS: The following themes emerged from the data (i) integrating HBV into HIV care is perceived to be feasible, fit and beneficial, after making requisite adjustments (ii) integration is acceptable due to the need for both free treatment and anticipated collaboration between HIV and HBV clients in terms of peer-support (iii) there are concerns about the likely rise in stigma and the lack of community awareness about integrated care. CONCLUSION: The integrated HIV/HBV care model is feasible and acceptable among both providers and recipients. Necessary adjustments to the existing care system, including training, for community sensitization on the reasons and significance of integration are required.

RESUMO

Failure to access antiviral medications is a leading cause of hepatitis B (HBV)-associated morbidity and mortality in sub-Saharan Africa (SSA). Despite guideline availability, SSA is not on course to meet its elimination targets. We characterized factors associated with antiviral medication use and challenges to offering chronic care in a large Ugandan institution. We abstracted HBV care data. 2,175/2,209 (98.5%) had HBV-infection. Most participants were men [1,197 (55%)]; median (IQR) age 27 years (19-35); 388/1689 (23.0%) had cirrhosis by sonography and 141/2175 (6.5%) by the aspartate aminotransferase to platelet ratio index (APRI) score ≥2. Of the eligible, 20/141 (14.2%) with APRI score ≥2 and 24/388 (6.2%) with sonographic evidence of liver cirrhosis were not on antiviral medications. Overall, 1,106 (51%) were on medications though 65.8% had not been fully investigated. In multivariate analysis, age ≥35 years [OR (95% CI) = 1.52 (1.01-2.28), p=0.043], APRI ≥2 [OR (95% CI) =1.79 (1.482.16), p<0.001], hepatitis B viral load >2,000IU/mL [OR (95% CI) = 6.22 (5.08-7.62), p<0.001] were associated with antiviral medications use. Over half of participants in care had not been fully evaluated although on treatment and many eligible patients did not access medications. There is need to bridge these gaps for SSA to realise its HBV elimination goals.

RESUMO

BACKGROUND: Hepatitis B and HIV care share health system challenges in the implementation of primary prevention, screening, early linkage to care, monitoring of therapeutic success and long-term medication adherence. SETTING: Arua regional referral hospital (RRH) and Koboko district hospital (DH), the West Nile region of Uganda. DESIGN: A cross-sectional hospital-based cost minimisation study from the providers' perspective considers financial costs to measure the amount of money spent on resources used in the stand-alone and integrated pathways. DATA SOURCES: Clinic inputs and procurement invoices, budgetary documents, open market information and expert opinion. Data were extracted from 3121 files of HIV and hepatitis B virus (HBV) monoinfected patients from the two study sites. OBJECTIVE: To estimate provider costs associated with running an integrated HBV and HIV clinical pathway for patients on lifelong treatment in low-resource setting in Uganda. OUTCOME MEASURES: The annual cost per patient was simulated based on the total amount of resources spent for all the expected number of patient visits to the facility for HBV or HIV care per year. RESULTS: Findings showed that Arua hospital had a higher cost per patient in both clinics than did Koboko Hospital. The cost per HBV patient was US$163.59 in Arua and US$145.76 in Koboko while the cost per HIV patient was US$176.52 in Arua and US$173.23 in Koboko. The integration resulted in a total saving of US$36.73 per patient per year in Arua RRH and US$17.5 in Koboko DH. CONCLUSION: The application of the integrated Pathway in HIV and HBV patient management could improve hospital cost efficiency compared with operating stand-alone clinics.

RESUMO

INTRODUCTION: The "2for1" project is a demonstration project to examine the feasibility and effectiveness of HBV care integrated into an HIV clinic and service. An initial phase in implementation of this project was the development of a specific training program. Our objective was to describe key features of this integrated training curriculum and evaluation of its impact in the initial cohort of health care workers (HCWs). METHODS: A training curriculum was designed by experts through literature review and expert opinion. Key distinctive features of this training program (compared to standard HBV training provided in the Government program) were; (i) Comparison of commonalities between HIV and HBV (ii) Available clinic- and community-level infrastructure, and the need to strengthen HBV care through integration (iii) Planning and coordination of sustained service integration. The training was aided by a power-point guided presentation, question and answer session and discussion, facilitated by physicians and hepatologists with expertise in viral hepatitis. Assessment approach used a self-administered questionnaire among a cohort of HCWs from 2 health facilities to answer questions on demographic information, knowledge and attitudes related to HBV and its prevention, before and after the training. Knowledge scores were generated and compared using paired t- tests. RESULTS: A training curriculum was developed and delivered to a cohort of 44 HCWs including medical and nursing staff from the two project sites. Of the 44 participants, 20 (45.5%) were male, average age (SD) was 34.3 (8.3) with an age range of 22-58 years. More than half (24, 54.5%) had been in service for fewer than 5 years. Mean correct knowledge scores increased across three knowledge domains (HBV epidemiology and transmission, natural history and treatment) post-intervention. However, knowledge related to diagnosis and prevention of HBV did not change. CONCLUSION: A structured HBV education intervention conducted as part of an HIV/HBV care integration training for health care workers yielded improved knowledge on HBV and identified aspects that require further training. This approach may be replicated in other settings, as a public health strategy to heighten HBV elimination efforts.

RESUMO

BACKGROUND: Infection prevention and control (IPC) practices are required to prevent nosocomial infection by severe acute respiratory syndrome coronavirus 2. In low- and middle-income countries, where resources are often limited, IPC practices are infrequently assessed. AIM: To assess the availability of the core components of World Health Organization (WHO) IPC practices at health facilities in Southwestern Uganda. METHODS: We assessed the availability of WHO IPC core components using a modified WHO IPC Assessment tool. We determined differences between government versus private ownership and by type of health facility. FINDINGS: We assessed 111 of 224 (50%) health facilities in four districts. The most frequently achieved core component of IPC strategies was environmental cleanliness with 75 of 111 (68%) facilities scoring >85%. The most infrequently achieved core component of IPC strategies was personal protective equipment (PPE) with only one of seven (14%) hospitals and no other facilities scoring >85%. Of the 20 hospital or health center IV facilities, five (25%) received an overall score of >85% compared to only one of 91 (1%) health center II or III facilities (odds ratio [OR] 30.0 [95% CI: 3.27-274.99], p=0.003). Of the 73 government facilities, two (3%) received an overall score of >85% compared to five of 38 (13%) private facilities (OR 0.24 [95% CI: 0.04-1.37], p=0.11). CONCLUSION: Few facilities in four districts in Southwestern Uganda achieved >85% availability of WHO IPC core components. Provision of PPE in these facilities should be prioritized.

RESUMO

BACKGROUND: The drive to eliminate viral hepatitis by 2030 is underway. However, locally generated data on active infection is required to focus such efforts. We performed a regionally-inclusive survey to determine prevalence of active HCV, genotypes and related factors among Ugandan blood donors. METHODS: Participants from regional blood banks and blood collection centers were surveyed for information on demographic, clinical and lifestyle factors. Blood was assayed for HCV infection, HCV genotypes and subtypes. Logistic regression was performed to determine factors associated with active HCV infection. RESULTS: Of 1243 participants, 1041 (83.7%) were male, average age (SD), 27.7 (9.8). Prevalence of active HCV infection was 7.8% and we identified 3 genotypes. Median age (adj. OR (95% CI) = 1.03 (1.01-1.06), p-value = 0.040)), Northern region of birth versus Central or Eastern (adj. OR (95% CI) = 10.25 (2.65-39.68), p-value = 0.001)), Northern residence, versus Central or Eastern (adj. OR (95% CI) = 0.23 (0.08-0.65), p-value = 0.006)), and being married (versus single/divorced) adj. OR 2.49(1.3-4.79), p-value = 0.006 were associated with active HCV infection. CONCLUSION: Targeted interventions in at-risk populations coupled with linkage to care and treatment will help achieve the WHO elimination goals in this setting.

RESUMO

BACKGROUND: HIV infection and opportunistic infections cause oxidative stress (OS), which is associated with tissue damage. Anti-retroviral therapy (ART) is used to treat HIV and decrease the risk of opportunistic infections, but it is unclear whether ART reduces OS. Association of ART with OS was investigated. METHODS: We stratified a convenience sample of frozen serum or plasma from HIV-infected, ART-naïve (n=21); HIV-infected, ART-treated (n=14); HIV and PTB co-infected, ART-naïve (n=21); HIV and PTB co-infected, ART-treated (n=25) patients. Controls (n=21) were HIV-negative adults without TB symptoms. Concentration of OS markers namely: transaminases (ALT and AST), gamma glutamyl transpeptidase (GGT), albumin, total protein, malondialdehyde (MDA), vitamin C, and total anti-oxidant status (TAS) were determined. RESULTS: AST (p<0.001), GGT (p<0.001), total protein (p=0.001) and MDA (p<0.001) were higher in HIV patients compared to controls. Vitamin C (P<0.0001) and albumin (p<0.01) were lower in HIV-patients relative to controls. ART was only associated with higher albumin (p=0.001), higher GGT (p=0.02) and lower vitamin C (p=0.009). HIV and PTB co-infection was only significantly associated with higher GGT (p=0.01) and AST (p=0.03). CONCLUSION: We identified severe OS among HIV-patients. ART was associated with both increased and reduced markers of OS hence suggesting that ART may not attenuate OS.

RESUMO

INTRODUCTION: Both Human Immunodeficiency Virus (HIV) and S.mansoni infections are common in Uganda and can cause liver disease. No study has determined co-infection significance in Uganda. We carried out a study on the burden, pattern and factors that contribute to peri-portal fibrosis (PPF) in HIV infected patients attending a Primary healthcare setting at Pakwach. METHODOLOGY: We conducted a cross-sectional study in the HIV clinic at Pakwach health centre IV. Data on demographics, contact with the Nile, CD4+ cell count, ART and alcohol use were collected. Urinary Circulating Cathodic Antigen (CCA), was done for S. Mansoni detection. Liver scan was done for presence and pattern of PPF. HBsAg testing was performed on all participants. Data was analyzed using Stata Version 10. RESULTS: We enrolled 299 patients, median age 39 years (IQR 16), most were female, 210 (73%). Overall, 206 (68.9%) had PPF, majority 191 (92.7%) had pattern c, either alone (63 participants) or in combination with pattern d (128 participants). Age of 30-50 years was significantly associated with PPF (OR 2.28 p-value-0.003). CONCLUSION: We found high prevalence of S. mansoni and PPF in the HIV infected population and age was a significant factor for PPF. We recommend all HIV infected patients be examined routinely for S. mansoni infection for early anti-schistosomal treatment.

RESUMO

OBJECTIVE: Antiretroviral therapy (ART) may interfere with replication of hepatitis B virus (HBV), raising the hypothesis that HBV infection might be prevented by ART. We investigated the incidence and risk factors associated with HBV among HIV-infected adults in Rakai, Uganda. METHODS: We screened stored sera from 944 HIV-infected adults enrolled in the Rakai Community Cohort Study between September 2003 and March 2015 for evidence of HBV exposure. Serum from participants who tested anti-hepatitis B core-negative (497) at baseline were tested over 3-7 consecutive survey rounds for incident HBV. Poisson incidence methods were used to estimate incidence of HBV with 95% confidence intervals (CIs), whereas Cox proportional regression methods were used to estimate hazard ratios (HRs). RESULTS: Thirty-nine HBV infections occurred over 3342 person-years, incidence 1.17/100 person-years. HBV incidence was significantly lower with ART use: 0.49/100 person-years with ART and 2.3/100 person-years without ART [adjusted HR (aHR) 0.25, 95% CI 0.1-0.5, P < 0.001], and with lamivudine (3TC) use: 0.58/100 person-years) with 3TC and 2.25/100 person-years without 3TC (aHR 0.32, 95% CI 0.1-0.7, P =  < 0.007). No new HBV infections occurred among those on tenofovir-based ART. HBV incidence also decreased with HIV RNA suppression: 0.6/100 person-years with 400 copies/ml or less and 4.0/100 person-years with more than 400 copies/ml (aHR, 6.4, 95% CI 2.2-19.0, P < 0.001); and with age: 15-29 years versus 40-50 years (aHR 3.2, 95% CI 1.2-9.0); 30-39 years versus 40-50 years (aHR 2.1, 95% CI 0.9-5.3). CONCLUSION: HBV continues to be acquired in adulthood among HIV-positive Ugandans and HBV incidence is dramatically reduced with HBV-active ART. In addition to widespread vaccination, initiation of ART may prevent HBV acquisition among HIV-positive adults in sub-Saharan Africa.

RESUMO

BACKGROUND: Co-infection with hepatitis B (HBV) and hepatitis D (HDV) is common among human immunodeficiency virus (HIV) infected individuals in developing countries and it aggressively accelerates progression of liver disease to cirrhosis and other complications. There is scarcity of data on HDV in sub-Saharan Africa .We investigated the sero-prevalence and factors associated with HDV antibody among HIV/HBV co-infected patients attending a large urban HIV clinic in Uganda. METHODS: We screened 189 HIV/HBV co-infected individuals for anti-HDV immunoglobulin G (IgG) and performed logistic regression to determine the associated factors. Socio-demographic, clinical data, immunological status, and liver fibrosis (as determined by the Aspartate transaminase to platelet ratio index and transient elastography) were included. RESULTS: Participants were predominately young and of sound immunologic status (median age 40 years, median CD4 440 cells/µl). 98% were on ART regimens containing anti-HBV active medications (95.2% were on TDF/3TC while 4.8% on 3TC containing regimen). Median duration on ART was 36 months (IQR 22-72). Anti-HDV was detected in 6/198, 3.2% (95% CI 1.14-6.92%), associated with male gender and a duration of more than 5 years since HIV diagnosis. CONCLUSIONS: The sero-prevalence of HDV antibodies among the HIV/HBV co-infected patients is low in a Ugandan urban cohort.

RESUMO

BACKGROUND: The prevalence of hepatitis B virus (HBV) infection in Uganda is 10%. Hepatitis B virus genotypes impact on treatment response, rate of spontaneous recovery and progression of chronic HBV infection and hepatocellular carcinoma. There is little information on the HBV genotypic distribution in Uganda. OBJECTIVES: To determine HBV genotypes in Uganda. METHODS: The MBN clinical laboratory performs HBV viral load and genotype testing in Uganda. It receives hepatitis B surface antigen (HBsAg)-positive samples from all over the country for additional HBV testing. Samples are stored for 6 months before being discarded. Our study used delinked stored samples. PCR-positive samples had DNA extracted and used as template for HBV genome amplification by nested PCR. Reverse hybridisation was performed and genotypes were determined by the line probe assay method (INNO-LiPA). RESULTS: One hundred stored HBsAg-positive plasma samples with detectable viral loads were analysed. Of these, 93 samples showed PCR amplification products and gave genotype-specific probe lines on the INNO-LiPA assay. Of the patients, where gender was recorded, 60.9% were female, and the overall median age (IQR) was 25 (2-60) years. There was a predominance of HBV genotype D (47 patients; 50.5%), followed by genotype A, (16 patients; 17.2%). One patient (1.1%) had genotype E. In 28% of the samples mixed infections were detected with genotypes A/E (9.7%) and A/D (6.5%) being most common. Genotypes B, C, E and H only occurred as part of mixed infections. CONCLUSION: Hepatitis B genotypes D and A were predominant in our study population.

RESUMO

BACKGROUND: Co-infection with hepatitis B (HBV) and hepatitis D (HDV) is common among human immunodeficiency virus (HIV) infected individuals in developing countries and it aggressively accelerates progression of liver disease to cirrhosis and other complications. There is scarcity of data on HDV in sub-Saharan Africa .We investigated the sero-prevalence and factors associated with HDV antibody among HIV/HBV co-infected patients attending a large urban HIV clinic in Uganda. METHODS: We screened 189 HIV/HBV co-infected individuals for anti-HDV immunoglobulin G (IgG) and performed logistic regression to determine the associated factors. Socio-demographic, clinical data, immunological status, and liver fibrosis (as determined by the Aspartate transaminase to platelet ratio index and transient elastography) were included. RESULTS: Participants were predominately young and of sound immunologic status (median age 40 years, median CD4 440 cells/µl). 98% were on ART regimens containing anti-HBV active medications (95.2% were on TDF/3TC while 4.8% on 3TC containing regimen). Median duration on ART was 36 months (IQR 22-72). Anti-HDV was detected in 6/198, 3.2% (95% CI 1.14-6.92%), associated with male gender and a duration of more than 5 years since HIV diagnosis. CONCLUSIONS: The sero-prevalence of HDV antibodies among the HIV/HBV co-infected patients is low in a Ugandan urban cohort.
