HIV viral suppression and risk of viral rebound in patients on antiretroviral therapy: a two- year retrospective cohort study in Northern Tanzania. BMC Infect Dis 2024; 24:390. [PMID: 38605325 PMCID: PMC11007878 DOI: 10.1186/s12879-024-09161-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 02/21/2024] [Indexed: 04/13/2024] Open
Abstract
BACKGROUND The world is moving towards the third target of the Joint United Nations Programme on HIV/AIDS to ensure most people receiving antiretroviral therapy (ART) are virologically suppressed. Little is known about viral suppression at an undetectable level and the risk of viral rebound phenomenon in sub-Saharan Africa which covers 67% of the global HIV burden.This study aimed to investigate the proportion of viral suppression at an undetectable level and the risk of viral rebound among people living with HIV receiving ART in northern Tanzania. METHODOLOGY A hospital based-retrospective study recruited people living with HIV who were on ART for at least two years at Kibong'oto Infectious Disease Hospital and Mawenzi Regional Referral Hospital in Kilimanjaro Region, Tanzania. Participants' two-year plasma HIV were captured at months 6, 12, and 24 of ART. Undetectable viral load was defined by plasma HIV of viral load (VL) less than 20copies/ml and viral rebound (VR) was considered to anyone having VL of more than 50 copies/ml after having history of undetectable level of the VL less than 20copies/ml. A multivariable log-binomial generalized linear model was used to determine factors for undetectable VL and viral VR. RESULTS Among 416 PLHIV recruited, 226 (54.3%) were female. The mean (standard deviation) age was 43.7 (13.3) years. The overall proportion of undetectable VL was 68% (95% CI: 63.3-72.3) and 40.0% had viral rebound (95% CI: 34.7-45.6). Participants who had at least 3 clinic visits were 1.3 times more likely to have undetectable VL compared to those who had 1 to 2 clinic visits in a year (p = 0.029). Similarly, participants with many clinical visits ( > = 3 visits) per year were less likely to have VR compared to those with fewer visits ( = 2 visits) [adjusted relative risk (aRR) = 0.64; 95% CI: 0.44-0.93]. CONCLUSION Participants who had fewer clinic visits per year(ART refills) were less likely to achieve viral suppression and more likely to experience viral rebound. Enhanced health education and close follow-up of PLHIV on antiretroviral therapy are crucial to reinforce adherence and maintain an undetectable viral load.

Abstract
Occult hepatitis B (OHB) is characterized by the presence of hepatitis B virus (HBV) DNA in the blood of individuals who test negative for the hepatitis B surface antigen (HBsAg). OHB in blood donors can lead to HBV transmission through transfusions, yet the prevalence of OHB in Basrah, Iraq, is unknown. This study aimed to determine the prevalence of OHB in blood donation centers in Basrah and investigate the immune response to HBV in OHB-positive donors. We recruited 450 blood donors and categorized them into four groups based on HBV markers: the HBsAg-negative/HBsAb-negative/HBcAb-positive group, the recovery group (HBsAg-negative/HBsAb-positive/HBcAb-positive), the patient group (HBsAg-positive/HBsAb-negative/HBcAb-positive), and the apparently healthy group (negative for all HBV markers). We measured levels of IgG, IgM, complement components (C3 and C4), ALT, AST, and serum ALP in OHB-positive donors. Of the 450 donors, 97 (21.6%) were OHB-positive. IgG levels were significantly higher than IgM levels in OHB-positive donors. Healthy and HBsAg-negative/HBsAb-positive donors had significantly lower C3 levels than patients. IgG levels were significantly higher than IgM in both the patient and recovery groups. C3 levels were higher than C4 levels in all groups. The serum ALP level was significantly higher in the patient group. OHB prevalence in Basrah blood donors is high, indicating the potential for HBV transmission. OHB-positive donors showed an immune response to HBV. Our study provides insights into OHB prevalence and immune response in Basrah, with implications for diagnostic and therapeutic approaches in blood donation centers.

Hepatitis B and C viral coinfections and their association with HIV viral load suppression among HIV-1 infected patients on ART at Mekelle hospital, northern Ethiopia. AIDS Res Ther 2022; 19:57. [PMID: 36457041 PMCID: PMC9714192 DOI: 10.1186/s12981-022-00479-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 11/04/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Although Ethiopia is endemic to viral hepatitis and HIV, data that could guide population-specific interventions are limited. In this study, we determined the seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) and assessed their associations with HIV-1 viral load suppression among HIV-1 infected patients on antiretroviral therapy (ART) at Mekelle hospital in northern Ethiopia. METHODS Between February and April 2020, blood samples were collected from 439 participants. Samples were screened for HBsAg and anti-HCV on the immunochromatographic test and confirmed using the Enzyme-Linked Immuno-sorbent assay (Beijing Wantai Co. China). HIV-1 viral load was quantified using reverse transcription-polymerase chain reaction (RT-PCR) on the Abbott platform. Binary and multivariable logistic regression was performed to identify potential predictors. RESULTS Overall, 10% (44/439) and 3.6% (16/439) of the participants were coinfected with HBV and HCV, respectively. In a multivariate analysis, being illiterate (AOR = 6.57; 95% CI 1.04-41.6), and having a history of sexually transmitted infections (AOR = 4.44; 95% CI 1.31-15.0) and multiple sexual partners (AOR = 29.9; 95% CI 7.82-114.8) were associated with HBV infection. On the other hand, participants with a history of chronic non-communicable diseases (AOR = 10.6, 95% CI 1.61-70.1), and those reporting a history of sexually transmitted infections (AOR = 5.21, 95% CI 1.39-19.5) were more likely to be infected with HCV. In further analysis, HCV infection status was significantly associated with decreased viral load suppression rate (AOR = 7.14; 95% CI 2.18-23.3) whereas no significant association was observed with the HBV infection. CONCLUSIONS The HBV coinfection rate in our study is high and, as per WHO's standard, corresponds to a hyperendemic level. The HCV coinfection rate is also substantially high and urges attention given its influence on the viral load suppression of HIV patients on ART at our study site. Our findings suggest the need to adopt universal screening and vaccination of people with HIV against HBV and screening for HCV at our study site and in Ethiopia at large, which contributes to Ethiopia's progress towards the 2030 global target of reducing the HBV infection.

Prevalence of HIV and Its Co-Infection with Hepatitis B/C Virus Among Chronic Liver Disease Patients in Ethiopia. Hepat Med 2022; 14:67-77. [PMID: 35591850 PMCID: PMC9113656 DOI: 10.2147/hmer.s365443] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Accepted: 05/06/2022] [Indexed: 12/11/2022] Open
Abstract
Background The efficient use of antiretroviral drugs has significantly reduced AIDS-related morbidities and mortalities; however, mortality due to non-AIDS-related end-stage liver diseases is escalating in those living with HIV. Objective The study was designed to determine the prevalence of HIV and its co-infection with HBV and HCV among chronic liver disease (CLD) patients in Ethiopia. Methods Three hundred and forty-five CLD patients were included in this study in two groups: Hepatocellular carcinoma (HCC) (n=128) and non-HCC (n=217) patients. The non-HCC group comprised patients with advanced liver disease (n=98) and chronic hepatitis (n=119). Enzyme immunoassays were used to determine HBV and HCV infection markers. In addition, a serial rapid HIV testing algorithm was employed to screen HIV infection. Results Regardless of the stage of liver disease, the overall frequency of HIV was 4.3% (15/345), with a 2% (7/345) and 0.3% (1/345) of HIV/HBV and HIV/HCV co-infection rate. Of all HIV-infected patients (n=15), 46.7% (7/15) and 6.7% (1/15) were co-infected with HBV (HBsAg+HBcAb+) and HCV (anti-HCV+ HCV-RNA+), respectively, and 86.7% (13/15) exhibited a marker of HBV exposure (total HBcAb+). Overall, the frequency of HIV and its co-infection with HBV was more noticeable among HCC than non-HCC patients [8.6% (11/128) vs 1.8 (4/217), p=0.005 and 3.9% (5/128) vs 0.9% (2/217), p=0.1]. The rate of HIV mono-infection was 3.9% (5/128) vs 0.9% (2/217) among HCC and non-HCC patients. Conclusion The frequency of HIV and its co-infections with HBV/HCV exhibited an increasing pattern with the severity of the liver disease. Thus, screening all HIV-positive patients for HBV and HCV infection and all CLD patients for HIV infection and taking necessary preventive measures would be an essential strategy to prevent the progression of CLD and death related to liver disease in people living with HIV.

HIV, hepatitis B virus, and hepatitis C virus co-infection among HIV positives in antiretroviral treatment program in selected hospitals in Addis Ababa: A retrospective cross-sectional study. PLoS One 2022; 17:e0267230. [PMID: 35452472 PMCID: PMC9032368 DOI: 10.1371/journal.pone.0267230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Accepted: 04/05/2022] [Indexed: 11/22/2022] Open
Abstract
Introduction HIV co-infection with hepatitis B (HIV-HBV) and hepatitis C (HIV-HCV) is known to affect treatment outcomes of antiretroviral therapy (ART); however, its magnitude is not well documented. We aimed to determine the magnitude of HIV-HBV and HIV-HCV co-infections simultaneously in people living with HIV (PLHIV) enrolled in ART care in Addis Ababa. Methods We reviewed the medical records of adults ≥15 years who were receiving ART care in three high burden hospitals in Addis Ababa. Baseline clinical and laboratory test results were extracted from medical records. Co-infection was determined based on hepatitis B surface antigen (HBsAg) and hepatitis C virus antibody (anti-HCV) tests obtained from the medical records. A multivariable logistic regression model was used to identify the risk factors for hepatitis B and C co-infections. Results A total of 873 HIV-positive participants were included in this study. The median age of the participants was 37.5 years, and 55.7% were women. Overall, HIV-HBV co-infection was 5.96% (95% CI: 4.56–7.74), and HIV-HCV co-infection was 1.72% (95% CI: 1.03–2.83). The multivariable logistic regression showed that the male sex was the most independent predictor for viral hepatitis B co-infection with an odds ratio of 2.42(95% CI:1.27–4.63). However, HIV-HCV co-infection did not show a significant association in any of the sociodemographic data of the participants. Conclusion HIV co-infection with hepatitis B was moderately high in individuals enrolled in ART care in Addis Ababa. Men had significantly higher HIV-HBV co-infection. HIV co-infection with hepatitis C was relatively low. Strengthening integrated viral hepatitis services with HIV care and treatment services should be emphasized to improve patient care in health facilities.

Prevalence of Hepatitis C Virus Infection among Pregnant Women in Ethiopia: A Systematic Review and Meta-Analysis. Adv Prev Med 2021; 2021:6615008. [PMID: 34136287 PMCID: PMC8177971 DOI: 10.1155/2021/6615008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 02/12/2021] [Accepted: 05/20/2021] [Indexed: 12/18/2022] Open
Abstract
Background Hepatitis C virus infection during pregnancy is associated with a high risk of maternal complications and poor birth outcomes. There are variable reports on the prevalence of hepatitis C virus infection among pregnant women in Ethiopia. Therefore, this study aims to estimate the pooled prevalence of hepatitis C virus infection among pregnant women in Ethiopia. Methods A comprehensive search of electronic databases including PubMed, Scopus, EMBASE, the Cochrane Library, Web of Sciences, and Google Scholar was conducted from April 03, 2020, to May 03, 2020. The quality of included article was evaluated by the JBI. Heterogeneity between the studies was assessed using Cochrane Q and I2 test. The presence of publication bias was tested by funnel plots and Egger's test. A random-effects meta-analysis was computed to determine the pooled prevalence of HCV infection among pregnant women. Results Of 502 studies, 6 studies with a total of 2117 pregnant women were included in the meta-analysis. The overall pooled prevalence of hepatitis C virus infection among pregnant women in Ethiopia was 1.83% (95% CI: 0.61, 3.06). Besides, subgroup analysis revealed that the highest HCV prevalence among pregnant women was observed in Oromia region, 5.10% (95% CI: −0.53, 10.73). Conclusions This study shows an intermediate level of HCV infection among pregnant women in Ethiopia. The finding suggests the need of implementing a routine hepatitis C virus screening program for all pregnant women, which enables women to access HCV antiviral treatment to minimize vertical transmission to the newborn infants. Moreover, national and regional health programs should mandate and monitor the screening procedures so as to reduce the risk of hepatitis C virus infection.

Seroprevalence of Hepatitis C Viral Infection in Ethiopia: A Systematic Review and Meta-Analysis. ScientificWorldJournal 2021; 2021:8873389.

Abstract
Background Hepatitis C virus is a highly genetically heterogenous bloodborne pathogen that is responsible for acute and chronic hepatitis. Globally, an estimated 71 million population is chronically infected with this virus from which 399,000 people die every year. Its prevalence is high in Ethiopia and varies from region to region, even among different studies within a region. Methods Electronic databases, including Science Direct, Medline, HINARI, African Journals Online, TRIP database, African Index Medicus, and Directory of Open Access Journals, searched from 2010 to 2020 and published articles were included. Due to evidence of considerable heterogeneity, the pooled prevalence of anti-HCV was analyzed using the random-effects model. The possible sources of heterogeneity were analyzed through subgroup analysis, sensitivity analysis, and meta-regression. Funnel plots and Egger's test statistics were used to determine the presence of publication bias. Results The analysis of 56 articles showed that the prevalence of anti-HCV in Ethiopia ranged from 0% to 22%. The pooled prevalence estimated was 2% (95% CI 2.0–3.0), and the meta-regression statistics indicated that the diagnostic method (p=0.037), study group (p=0.005), and level of bias (p=0.035) showed statistically significant association with the outcome variable. The sensitivity analysis claims no influence on the overall effect estimate while removing a single study from the analysis at a time. Egger's test statistics (p ≤ 0.001) declare the presence of publication bias that is handled using time and fill analysis. Conclusions The pooled prevalence of anti-HCV in Ethiopia was high. Predictor variables, including the diagnostic method, study group, and level of bias, showed a statistically significant relationship with the outcome variable. Strengthening the scope of existing prevention and control programs and implementing novel approaches, including screen-and-treat, could significantly help to tackle this critical public health issue. The study provides a current estimate which is valuable for policymakers and other responsible bodies.

Abstract
The absence of hepatitis B surface antigen (HBsAg) and the presence of antibody to hepatitis B core antigen (anti-HBc) in the blood of apparently healthy individuals may not indicate the absence of circulating hepatitis B virus (HBV) and might be infectious. Despite the risk of HBV transmission, there has been no report from Ethiopia examining this issue; therefore, this study determined occult HBV infection (OBI) among isolated anti-HBc (IAHBc) HIV negative and HIV positive individuals on ART in eastern Ethiopia. A total of 306 IAHBc individuals were included in this study. DNA was extracted, amplified, and detected from plasma using a commercially available RealTime PCR platform (Abbott m2000rt) following the manufacturer's instructions. Data were entered into EPI Data version 3.1, cleaned, and analyzed using Stata version 13. Descriptive analysis was used to calculate prevalence, summarize sociodemographic data and other factors. From the 306 IAHBc individuals (184 HIV positive and 122 HIV negative) included in the study, 183 (59.8%) were female of which 142 (77.6%) were within the reproductive age group. DNA extraction, amplified and detection was conducted in 224 individuals. The overall OBI prevalence was 5.8% (5.6% in HIV negative and 6% in HIV positive) among the IAHBc individuals. The HBV DNA concentration among the occult hepatitis B individuals was < 200 IU/mL, indicating a true occult. This study reported the burden of OBI, which pauses a significant public health problem due to the high burden of HBV infection in the country. OBI may cause substantial risk of HBV transmission from blood transfusion, organ transplantation as well as vertical transmission as screening is solely dependent on HBsAg testing.

Abstract
Globally, in 2017 35 million people were living with HIV (PLHIV) and 257 million had chronic HBV infection (HBsAg positive). The extent of HIV-HBsAg co-infection is unknown. We undertook a systematic review to estimate the global burden of HBsAg co-infection in PLHIV. We searched MEDLINE, Embase and other databases for published studies (2002-2018) measuring prevalence of HBsAg among PLHIV. The review was registered with PROSPERO (#CRD42019123388). Populations were categorized by HIV-exposure category. The global burden of co-infection was estimated by applying regional co-infection prevalence estimates to UNAIDS estimates of PLHIV. We conducted a meta-analysis to estimate the odds of HBsAg among PLHIV compared to HIV-negative individuals. We identified 506 estimates (475 studies) of HIV-HBsAg co-infection prevalence from 80/195 (41.0%) countries. Globally, the prevalence of HIV-HBsAg co-infection is 7.6% (IQR 5.6%-12.1%) in PLHIV, or 2.7 million HIV-HBsAg co-infections (IQR 2.0-4.2). The greatest burden (69% of cases; 1.9 million) is in sub-Saharan Africa. Globally, there was little difference in prevalence of HIV-HBsAg co-infection by population group (approximately 6%-7%), but it was slightly higher among people who inject drugs (11.8% IQR 6.0%-16.9%). Odds of HBsAg infection were 1.4 times higher among PLHIV compared to HIV-negative individuals. There is therefore, a high global burden of HIV-HBsAg co-infection, especially in sub-Saharan Africa. Key prevention strategies include infant HBV vaccination, including a timely birth-dose. Findings also highlight the importance of targeting PLHIV, especially high-risk groups for testing, catch-up HBV vaccination and other preventative interventions. The global scale-up of antiretroviral therapy (ART) for PLHIV using a tenofovir-based ART regimen provides an opportunity to simultaneously treat those with HBV co-infection, and in pregnant women to also reduce mother-to-child transmission of HBV alongside HIV.

Ayana DA, Mulu A, Mihret A, Seyoum B, Aseffa A, Howe R. Hepatitis B virus seromarkers among HIV infected adults on ART: An unmet need for HBV screening in eastern Ethiopia. PLoS One 2019; 14:e0226922. [PMID: 31887187 PMCID: PMC6936828 DOI: 10.1371/journal.pone.0226922] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 12/07/2019] [Indexed: 02/08/2023] Open
Abstract
Progression of chronic HBV to cirrhosis, end-stage liver disease (ESLD), and hepatocellular carcinoma (HCC) is more rapid in HIV positive individuals than those with HBV alone; however, the distribution of HBV seromarkers in HIV infected individuals on antiretroviral therapy (ART) is not well described. To address this problem, we assessed the distribution of hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc) and hepatitis B surface antibody (anti-HBs) among HIV infected adults on ART in Eastern Ethiopia. A cross-sectional study was conducted from September 2017 to February 2018. Socio-demographic, behavioral and health related factors, and clinical data were collected using questionnaire and checklist. Plasma samples were tested for HBsAg, anti-HBc and anti-HBs seromarkers using ELISA. Data were double entered into EpiData 3.1, cleaned, exported to and analyzed using STATA 13. Descriptive and logistic regression analysis were conducted and statistical significance was decided at p≤0.05. A total of 901 participants were included and the prevalence of HBsAg was found to be 11.7% [95%CI (10, 14)]. Among the co-infected, 47.6% were also positive for anti-HBc, of which 58% were on an ART containing tenofovir (TDF). Among those screened for the three seromarkers, 38.1% were negative for all and 21% were positive only for anti-HBc (IAHBc). Being single, history of genital discharge and taking ART with TDF combination were significantly associated with HBV co-infection (p≤0.05). There is high burden HBV co-infection among individuals on ART. The unmet need of HBV screening prior to ART initiation leaves many co-infected individuals without appropriate management including therapy, close monitoring or vaccination when indicated, impacting disease prevention.

Taye BW. A Path to Ending Hepatitis C in Ethiopia: A Phased Public Health Approach to Achieve Micro-Elimination. Am J Trop Med Hyg 2019; 101:963-972. [PMID: 31516107 PMCID: PMC6838594 DOI: 10.4269/ajtmh.19-0295] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Accepted: 08/20/2019] [Indexed: 12/12/2022] Open
Abstract
Ethiopia's hepatitis C virus (HCV) prevalence is predicted to rise by 2030. To halt this increasing trend, a suitable approach to the elimination of HCV is needed. This review explores the current status, challenges, and opportunities and outlines a strategy for the micro-elimination approach in Ethiopia. I searched PubMed and EMBASE using combined Medical Subject Heading databases for the literature on HCV micro-elimination. A phased public health approach to HCV micro-elimination, including preparation/capacity building (phase I), implementation (phase II), and rollout and scale-up (phase III), targeting people living with HIV, prisoners, chronic hepatitis and cancer patients, blood donors, and pregnant women is a pragmatic strategy to Ethiopia. This can be implemented at general and tertiary care referral hospitals with a future scale-up to district hospitals through task-shifting by training general practitioners, nurses, laboratory technologists, and pharmacists. Availability of the highly effective direct-acting antivirals (DAAs) can be ensured by expanding the existing program that provides highly subsidized DAAs through an agreement with Gilead Sciences, Inc. and eventually aiming at domestic generic manufacturing. The significant enablers to HCV micro-elimination in Ethiopia include the control of healthcare-associated HCV infection, blood safety, access to affordable testing and pan-genotypic DAAs, task-shifting, multisectoral partnership, and regulatory support. General population-based HCV screening and treatment are not cost-effective for Ethiopia because of high cost, program complexity, and disease epidemiology.

Seroprevalence and associated factors of hepatitis B virus infection among HIV-positive adults attending an antiretroviral treatment clinic at Wolaita Sodo University Referral Hospital. Hepat Med 2019; 11:137-147. [PMID: 31565003 PMCID: PMC6735655 DOI: 10.2147/hmer.s206870] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Accepted: 06/19/2019] [Indexed: 12/19/2022] Open
Abstract
Background Hepatitis B virus infection (HBV) constitutes major public health problems in sub-Saharan Africa from different infections occuring in HIV positive patients. Ethiopia is a part of sub-Saharan Africa with 1.5% adult HIV prevalence, and also belongs to the intermediate to high HBV prevalence category. Hence, this study aimed to measure the seroprevalence and associated factors of HBV infection among HIV-positive adults attending an antiretroviral treatment (ART) clinic at Wolaita Sodo University Referral Hospital. Methods An institution-based cross-sectional study was conducted from October 15 to December 10, 2017 using a systematic random sampling technique. After getting informed written consent, data were collected by a structured and interviewer-administered questionnaire. Venous blood was collected and centrifuged to separate serum. Hepatitis B surface antigen (HBsAg) was detected from serum using an advanced quality one-step rapid test kit. Data were entered into EpiData version 3.01 and exported to SPSS version 20. Summary statistics, bivariate analysis, and multivariate analyses were performed. The variables having significant association of P<0.05 in the multivariate logistic regression were taken as independent factors. OR and 95% CI were used to measure the strength of the association. Results A total of 442 study participants, 187 males and 255 females, were included in this study. Overall prevalence of HBsAg was 37 (8.4%). Family history of HBV (adjusted OR=8.83, 95% CI=2.56–30.49), multiple sexual partners (adjusted OR=7.08, 95% CI=2.29–21.9), and CD4 count <200 cells/μL (adjusted OR=15.34, 95% CI=4.77–49.3) were found to be significantly associated with HBsAg positivity. Conclusion The prevalence of HBsAg in this study was high. Family history of HBV, multiple sexual partners, and CD4 count <200 cells/μL were independently associated with HBsAg positivity. Therefore, screening for HBV is recommended before initiation of ART in HIV patients and providing appropriate treatment for co-infection. Furthermore, accurate information on risk factors for HBV transmission should be provided. ![]()

Sero-prevalence of Hepatitis B and C viral co-infections among HIV-1 infected ART-naïve individuals in Kumasi, Ghana. PLoS One 2019; 14:e0215377. [PMID: 31002687 PMCID: PMC6474602 DOI: 10.1371/journal.pone.0215377] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Accepted: 04/01/2019] [Indexed: 12/28/2022] Open
Abstract
Background The study assessed the hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infection paradigm among the human immunodeficiency virus (HIV) infected patients attending a tertiary hospital in Ghana. Also, the immunological and virological characterisation of these viruses, prior to antiretroviral therapy (ART) initiation was investigated. Method A total of 400 HIV infected (HIV type-1) treatment naïve subjects ≥18 years were enrolled and tested for HBsAg and anti-HCV. Hepatitis B virus serological profile was performed on samples that were HBV positive. CD4+ T-cell count and HIV-1 RNA viral loads were determined using BD FacsCalibur analyzer (USA) and COBAS AmpliPrep/COBAS TaqMan Analyzer (USA) respectively. Results The overall prevalence of HBV/HCV co-infection among the HIV-1 patients was 18.0%. The prevalence of HIV-HBV and HIV-HCV co-infections were 12.5% and 5.5% respectively. The prevalence of active viral hepatitis (HBeAg-positive) among HIV-HBV co-infected patients was 40%. None of the patients had anti-HBc IgM. HIV-HBV co-infection was associated with lower CD4+ T-cell count as well as higher HIV-1 viral load compared to both HIV mono- infection and HIV-HCV co- infection (p<0.05) respectively. HBeAg positivity was associated with severe immunosuppression and higher HIV viral load. Patients aged 18–33 years [aOR = 9.66(1.17–79.61); p = 0.035], male gender [aOR = 2.74(1.15–6.51); p = 0.023], primary education [aOR = 9.60(1.21–76.08); p = 0.032], secondary education [aOR = 14.67(1.82–118.08); p = 0.012] and being single [aOR = 2.88(1.12–7.39); p = 0.028] were independent risk factors of HIV-HBV co-infections but not HIV-HCV co-infections. Conclusion The present study highlights the predominance of HBV exposure among the HIV infected patients in Ghana. HBV coinfection was associated with severe immunosuppression and higher HIV-1 viral load.

Abstract
Background Non-alcoholic Fatty Liver Disease (NAFLD) among type 2 diabetic patients is completely ignored in developing regions like Africa paving the way for public health and economic burden in the region. Therefore, the main objective of this research was to evaluate non-alcoholic fatty liver disease and associated factors among type 2 diabetic patients in Southwestern Ethiopia attending Diabetic Clinic of Jimma University Specialized Hospital (JUSH). Methods Facility based cross-sectional study design was used. Anthropometry, fatty liver (using utrasonography), liver enzymes, and lipid profiles were measured among type 2 diabetic patients who fulfilled the inclusion criteria. Socio-demographic and clinical characteristics were assessed using standard questionnaires. Results Ninety-six (96) type 2 diabetic patients were enrolled and non-alcoholic fatty liver disease prevalence was 73%. Of non-alcoholic fatty Liver disease documented patients, 35.4%, 31.3% and 6.3% exhibited mild, moderate and severe fatty liver diseases, respectively. Alanine aminotransferase (p ≤0.001), Triacyglycerol (p ≤0.001), total bilirubin (p ≤0.05), direct bilirubin (p ≤0.05) and diabetic duration (p ≤0.01) were significantly associated with non-alcoholic fatty liver disease among type 2 diabetic patients. The Aspartate aminotransferase/Alanine aminotransferase ratio among non alcoholic fatty liver disease patients was greater than one. Conclusions The magnitude of non-alcoholic fatty liver disease is high among study groups and it needs urgent action by healthcare systems. Therefore, targeted treatment approach inclusive of non-alcoholic fatty liver disease should be designed.

The burden of hepatitis B virus (HBV) infection, genotypes and drug resistance mutations in human immunodeficiency virus-positive patients in Northwest Ethiopia. PLoS One 2017; 12:e0190149. [PMID: 29281718 PMCID: PMC5744989 DOI: 10.1371/journal.pone.0190149] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Accepted: 12/09/2017] [Indexed: 12/24/2022] Open
Abstract
Background In sub-Saharan Africa, the hepatitis B virus (HBV) and human immunodeficiency virus (HIV) infections are endemic. Although there has been great progress in HIV care, universal HBV vaccination and care is lacking. In this study, we aimed to determine the prevalence of HBV, HBV genotypes, and drug resistance mutations in dual infected cases in a cohort of HIV patients in Northwest Ethiopia. Methods A total of 308 HIV-1 positive patients were enrolled into the study and tested for HBsAg in plasma. In HBsAg positive samples, HBV DNA was analyzed for HBV genotype using in-house nested PCR with HBV-specific pre-core / core or surface primers, and for HBV drug resistance mutations (DRMs) in polymerase region. Odds ratio at 95% confidence interval was calculated. Results Of the 308 HIV-positive subjects, 62.7% were female, median age 38 years (range 18–68, IQR: 27–49), and the median CD4 count 405 cells/μl (IQR: 75–734). Overall, 94.2% were on antiretroviral therapy (ART) frequently with combinations of Zidovudine (AZT)- Lamivudine (3TC)—Nevirapine (NVP). HBsAg was detected in 5.5% (95%CI 2.95–8.08%) of the study participants, of which the majority were infected with HBV genotype A (7A, 2E, 2D, 1C, 1 G). All HIV/HBV positive cases were on ART with anti-HBV activity (i.e., 3TC) and 3TC associated HBV DRMs (i.e., rtV173L, rtL180M, and rtM204V) were detected in 7/13 (53.8%) subjects. Conclusion In this cross-sectional study of HIV-infected individuals, we found 5.5% HBV/HIV co-infected cases. Most were receiving the first generation anti-HBV therapy with a low genetic barrier to resistance, and several carried mutations associated with anti-HBV (3TC) drug resistance. These data underscore the importance of integrating HBV screening to the HIV treatment guidelines for better management and prevention of HBV-related liver disease.

[PMID: 27993129 PMCID: PMC5168848 DOI: 10.1186/s12879-016-2090-1] [Citation(s) in RCA: 83] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2016] [Accepted: 12/03/2016] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The existing seroepidemiological data on viral hepatitis in Ethiopia showed a wide variation in prevalence pattern and the clinical and public health burden have been underestimated. The aim of this systematic review and meta-analysis was to provide a clear and comprehensive estimation of viral hepatitis epidemiology and the potential clinical burdens in Ethiopia. METHODS A comprehensive literature search was carried out from five decades (1968-2015) published studies from biomedical databases; PubMed, Google scholar, Medline and Web of Science. RESULTS The overall pooled prevalence of hepatitis B virus (HBV) was 7.4% (95%CI: 6.5-8.4). The pooled prevalence among subgroups showed 5.2% (95%CI: 3.7-7.4) in human immunodeficiency virus (HIV) infected individuals, 8.0% (95%CI: 5.9-10.7) in community based studies, 8.4% (95%CI: 5.4-12.7) in blood donors, 11.0% (95%CI: 7.5-15.9) in immigrants and 6.9% (95%CI: 5.6-8.5) in other groups. Among study parameters considered during meta-regression analysis, only study years were associated with a decreasing HBV prevalence rate over time. The overall pooled prevalence of anti-hepatitis C virus antibody (anti-HCV) was 3.1% (95%CI: 2.2-4.4). Unlike HBV, the anti-HCV prevalence in HIV infected individuals was higher (5.5%, 95%CI: 3.8-7.8%, p = 0.01) than the prevalence observed in the other subgroup of study population. Although relatively few data were available, hepatitis virus A (HAV), D (HDV) and E (HEV) were also circulated in Ethiopia. CONCLUSIONS This review indicates that all types of viral hepatitis origins are endemic in Ethiopia. Adapting a recommended diagnostic and treatment algorithm of viral hepatitis in the routine healthcare systems and implementing prevention and control policies in the general population needs an urgent attention.
