Community-based sero-prevalence of hepatitis B and C infections in South Omo Zone, Southern Ethiopia

Knowledge, attitude, and practice towards hepatitis B and C virus infection and associated factors among adults living at selected woredas in Gamo Zone, Southern Ethiopia: a cross-sectional study

BACKGROUND

Hepatitis is an inflammation of the liver tissue. It is one of the serious public health problems. Though an individuals' knowledge, attitude, and practice level is very vital in order to ensure the control of its adverse health impacts, little is known regarding these issues in the community level. Therefore, this study was aimed to assess knowledge, attitude, and practice towards hepatitis B and C virus infection and associated factors among adults living at selected woredas in Gamo Zone, Southern Ethiopia.

METHODS

Community based cross-sectional study design was conducted among 633 adults living at selected woredas in Gamo Zone, Southern Ethiopia. Data were collected by pretested, well-structured questionnaire. The collected data were checked, coded and entered into Epi-data version 4.6.0.2 and were exported to SPSS version 25 for analyses. Bivariable and multivariable logistic regression were done to identify independent factors associated with knowledge, attitude, and practice towards hepatitis B and C virus infection.

RESULTS

According to this study, 366(58.1%), 95% CI: (54.23-61.96) of the participants had good knowledge. 381(60.5%), 95% CI: (56.65-64.30) of the participants had favourable attitude. 317(50.3%), 95% CI: (46.40-54.23) of the participants had good practice. From factor analysis, sex, number of sexual partners, sharing sharp material, and vaccination status were significantly associated with knowledge; residence, occupational status, income level, sharing sharp material, and vaccination status were significantly associated with attitude; and residence, occupational status, and vaccination status were identified to be significantly associated with practice towards Hepatitis B and C virus infection.

CONCLUSION

Based on the study findings, it could be observed that good knowledge, favourable attitude, and good practice were indicated nearly above the half, only by half, and nearly above the half of the study participants respectively. Implementing actions that could increase awareness regarding limiting the number of sexual partner, not sharing sharp materials, and urbanization is recommended. Moreover, woreda administrators, and other related authorities should consider knowledge, attitude, and practice as an implementation area, and also it would be better to create an opportunities to promote vaccination practices.

Frequency of viral infections in adolescent and adult in-patient Ethiopians with acute leukemia at presentation to a tertiary care teaching hospital: a cross-sectional study

BACKGROUND

Leukemic patients are prone to infectious agents such as viruses due to dysregulated immune system resulting from infiltration of the bone marrow by malignant cells, chronic stimulation, reactivation of some viruses and viral pathogenicity as well as rarely from acquisition of a new infections leading to severe complications. However, the prevalence of these infections has not been systematically documented in resource-limited settings such as Ethiopia.

OBJECTIVE

To determine the prevalence of HBV, HCV, and HIV among adult and adolescent in-patients with acute leukemia before the administration of chemotherapy, at the Tikur Anbessa Specialized Hospital (TASH) in Addis Ababa, Ethiopia.

METHODS

A cross sectional study was conducted on 176 adult and adolescent inpatient Ethiopians, who were diagnosed with acute leukemia from April 2019 to June 2021. Socio-demographic characteristics and relevant clinical data were collected. Peripheral blood samples were collected and tested for HBV, HIV, and HCV using Enzyme-Linked Immunosorbent Assay (ELISA) and real-time PCR. Chi-square tests were used to assess associations between variables.

RESULTS

Of the 176 patients, 109(62%) were males. The median age was 25[IQR,18-35] yr, with a range from 13 to 76 year. The prevalence of HBV (positivity for HBsAg plus HBV DNA), HCV and HIV was 21.6%, 1.7%, and 1.7%, respectively. HBsAg was positive in 19 cases (10.8%). Among 157 HBsAg negative patients, 52(33.1%) were positive for Anti-HBcAg; of these seropositive cases, 47.5% were positive for HBV DNA. Most DNA positive, HBsAg negative cases (79.0%) had DNA concentrations below 200 IU/ml indicating true occult HBV infection (OBI). Of the 176 cases, 122 had a history of blood transfusions, but no statistically significant association was found between HBV infection and blood product transfusion history (P = 0.963).

CONCLUSIONS

The prevalence of HBV, HIV and HCV in patients with acute leukemia was similar to the national prevalence level of these infections. Given the HBsAg positivity and the high prevalence of occult hepatitis B infection in our study, these patients may be at increased risk for chemotherapy related hepatitis flares. Hence, clinicians caring these patients are strongly advised to screen their patients for HBV and also for HIV and HCV infections routinely.

Cancer signs and risk factors awareness in Addis Ababa, Ethiopia: a population-based survey

BACKGROUND

There is a paucity of data on public awareness of cancer in Ethiopia. This study assessed cancer signs, symptoms, and risk factors awareness among individuals aged 18 and older in Addis Ababa, Ethiopia.

METHOD

A population-based face-to-face interview was conducted applying a validated cancer awareness measure (CAM) tool. A total of 600 adults (315 males and 285 females) were recruited using a multistage sampling technique. One open-ended and ten closed-ended questions were used to assess awareness of cancer signs and symptoms. To assess awareness of cancer risk factors, one open-ended and twelve closed-ended questions were used. Logistic regression analysis was used to test the association between sociodemographic status and awareness of cancer signs, symptoms, and risk factors.

RESULTS

Based on the responses for the open-ended questions, unexplained bleeding (23.16%) and smoking (24.17%) were the most frequently recalled cancer sign and risk factor, respectively. Based on the responses for the closed questions, the majority of respondents identified tiredness all the time (80.7%) as a cancer symptom and alcohol use (82.5%) as a cancer risk factor.  The odds of cancer signs and symptoms awareness was higher in those with primary (AOR = 4.50, 95% CI, 1.72-11.79, p = 0.02), secondary (AOR = 4.62; 95% CI 1.86-11.43; p = 0.001), and tertiary (AOR = 7.51; 95% CI 3.04-18.56; p < 0.001) education than those who were illiterate. The odds of awareness about cancer signs and risk factors was 0.28 (95% CI 0.12-0.65; p = 0.003) and 0.22 (95% CI 0.83-0.58; p = 0.002) times lower, respectively, among individuals aged 60 and older than those aged 18 to 29.

CONCLUSIONS

Young adults who attended formal education of primary or higher level may have a better cancer signs and symptoms awareness. Future education interventions to increase awareness of the society in Addis Ababa may target illiterate and the elderly.

Undiagnosed Seroprevalence of Hepatitis B and C Virus Infections in the Community of Wolaita Zone, Southern Ethiopia

Background

Despite Ethiopia’s hepatitis endemic status with intermediate to hyperendemic level, there is no national strategy for monitoring, preventing, and controlling viral hepatitis. In order to advise community-based intervention programs, studies on the magnitude, determinant factors, and understanding of indigenous social organization are important. Thus, this study examined undiagnosed seroprevalence and associated factors for HBV and HCV infections among community members in Wolaita Zone, Southern Ethiopia.

Methods

A cross-sectional study was conducted on 320 individuals from randomly selected two woredas in the Wolaita Zone to determine the magnitude of HBV and HCV. Multistage sampling was used to select participants. Relevant clinical and sociodemographic data were collected using a structured questionnaire. One test strip technique was used for the screening of hepatitis B surface antigen and for antibodies against HCV. Both tests were confirmed by ELISA methods. The associated factors were assessed using bivariate and multivariate logistic regression analyses. P-values less than 0.05 were considered statistically significant.

Results

The seroprevalence for HBV infection was 6.6% (95% CI: 4.22%, 8.69%) using a one-step HBsAg test strip and 5.6% (95% CI: 3.47%, 8.58%) using confirmatory test (ELISA). The two tests had a very good agreement (K = 0.918; SE = 0.047; P < 0.001). The overall seroprevalence for HCV infection was 1.9% (95% CI: 0.9%, 3.0%). All four of the one-step HCV test strip positives were also positive by ELISA. One (0.3%) of the participants was co-infected with HBV and HCV. Hospital admission (AOR = 0.22; 95% CI = 0.5–0.95) and needle stick (AOR = 0.15; 95% CI = 0.07–0.72) were independently associated with HBV infections.

Conclusion

According to the current study, in Wolaita community, there is endemic to HBV at a higher-intermediate level and to HCV at a low level. It would be imperative to increase awareness of transmission modes and prevention of infection, as well as vaccination, in order to reduce the burden of both HBV and HCV.

Magnitudes and Correlates of Human Immunodeficiency Virus, Hepatitis B Virus, and Syphilis among Pregnant Mothers Attending Antenatal Care in Addis Ababa, Ethiopia

Background

Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and syphilis are major sexually transmitted infections (STIs) among the general population in Ethiopia, which in turn result in a wide range of adverse pregnancy outcomes. Hence, it is important to determine the seroprevalence and risk factors of HIV, HBV, and syphilis infection among pregnant mothers attending antenatal care in Addis Ababa, Ethiopia.

Method

A cross-sectional study was conducted among 286 pregnant women from February 1, 2021, to March 30, 2021, in four selected public hospitals in Addis Ababa. Sociodemographic, risky sociocultural, behavioral, and hospital-related factors were collected using an interview-administered questionnaire. Detection of anti-HIV antibodies, hepatitis B surface antigen (HBsAg), and rapid plasma reagin (RPR) for syphilis was conducted. A binary logistic regression analysis was used to determine predictors of STIs using SPSS version 25.

Result

A total of 281 pregnant mothers with a mean age of 27.5 (SD 4.6) completed the study. Among the participants, the seroprevalence rates of HIV, HBV, and syphilis were 15 (5.3%), 9 (3.2%), and 5 (1.8%), respectively. Twenty six (9.3%) of the participants tested positive for any one of the STIs, and 3 (1.1%) of the women had HIV and syphilis coinfections. History of multiple sexual partners (AOR 3.42, 95% CI: 1.6-11.63) and STIs (AOR 3.7; 95% CI: 1.70-13.45) were significantly associated with HIV infection. Likewise, history of abortion (AOR 7.65, 95% CI: 1.17-49.74), tattooing (AOR 9.72, 95% CI: 1.41-66.73), and rape (AOR 9.72, 95% CI: 1.41-66.73) were significantly associated with hepatitis B virus infection. Husband history of multiple sexual partners (AOR 20.9, 95% CI: 1.8-241.8) was significantly associated with syphilis infection. The educational level of participants, history of tattooing (AOR 6.24, 95% CI: 1.79-21.7), and history of multiple sexual partners (AOR 5.15, 95% CI: 1.68-15.7) were independent predictors of infection with any one of the STIs.

Conclusion

There is still a high burden of HIV, HBV, and syphilis among pregnant mothers in Ethiopia. History of multiple sexual partners, abortion, rape, and tattooing was a significant predictor of STIs.

A Primary Screening Method for Liver Cancer in Chronic Hepatitis B Carriers: A Prospective Community-Based Cohort Study

Background

Patients with hepatitis B virus (HBV) were invited to receive ultrasound and alpha-protein examination directly in China. However, not all HBV carriers need to be subjected to further tests. This study aimed to develop a feasible primary screening method to narrow down potential high-risk individuals of liver cancer among populations with HBV.

Methods

Based on a prospective community-based cohort, potential risk factors were selected as the predictors, including age, sex, smoking, alcohol consumption, diabetes, liver cancer family history, liver diseases in mothers, source of water, body mass index (BMI), and psychological trauma. Cox proportional regression model was applied to predict the 3-year absolute risk of liver cancer and derive risk scores. The area under receiver operating characteristic curve (AUROC) and calibration plot were used to assess the performance of the model. Bootstrap resampling was used for internal validation.

Results

Age, sex, BMI, alcohol consumption, liver diseases in mothers, and psychological trauma were independent risks of liver cancer. The 1- to 3-year AUROC of the prediction model was 71.15% (95% CI, 66.88–75.42), 71.16% (95% CI, 67.42–74.90), and 72.95% (95% CI, 64.20–81.70), respectively. The predicted risk was calibrated well with the observed liver cancer risk. Bootstrap resampling showed that C-index was 0.70 (0.67–0.74). A 32-point risk score was also developed and a score over 5 was identified for patients at extremely high risk.

Conclusions

A user-friendly primary screening method was created that could estimate the 3-year absolute risk of liver cancer and identify extremely high-risk individuals among the population with HBV.

Seroprevalence and Associated Factors of Hepatitis B and C Virus Among Pulmonary Tuberculosis Patients Attending Health Facilities in Gondar Town, Northwest Ethiopia

Background

Hepatitis B virus (HBV) and hepatitis C virus (HCV) are hepatotropic viruses whose primary replication occurs in the liver. Despite the significant clinical importance of early screening of hepatitis B and C virus infection in decreasing the hepatotoxicity effect of anti-tuberculosis drugs, screening of hepatitis B and C virus among tuberculosis (TB) patients before treatment has not been practiced in Ethiopia. Thus, this study was conducted to determine the seroprevalence and associated factors of HBV and HCV infections among pulmonary TB (PTB) patients attending health facilities in Gondar, Northwest Ethiopia.

Methods

A cross-sectional study was conducted among 145 bacteriologically confirmed PTB patients from January 1 to May 30, 2019. After obtaining a signed informed consent from each participant, data on socio-demographic, clinical, and associated factors were collected using a structured pre-tested questionnaire. Besides, a blood sample was collected to determine HBsAg and HCV antibodies by enzyme linked immune sorbent assay (ELISA). The data were entered and analyzed using SPSS version 21. A Fisher's exact test was used to see the relationship between dependent and independent variables, and a p-value ≤0.05 was considered as statistically significant.

Results

Out of the 145 PTB patients screened, 5 (3.4%) patients tested positive for HBsAg, yet none of them were found to be positive for anti-HCV. Besides, the proportion of HIV-positive was 12 (8.3%). History of hospital admission (P= 0.005), tattooing (P= 0.009) and dental extraction (P=0.003) were significantly associated with HBsAg.

Conclusion

Although anti-HCV antibodies were not detected, the prevalence of HBV was relatively high in tuberculosis patients. This study highlights the need for the introduction of routine screening of viral hepatitis markers for all TB patients before anti-TB treatment for better management of patients. Likewise, further clinical and epidemiological studies are needed.

[Seroprevalence of viral hepatitis B and its associated factors determined based on data from a screening campaign targeting the general population in Benin]

INTRODUCTION

hepatitis B is a global public health problem. The purpose of this study was to determine the prevalence of hepatitis B virus (HBV) and its associated factors based on data from a mass screening in several localities across Benin.

METHOD

we conducted a cross-sectional descriptive and analytical study with prospective data collection. Data collection was carried out during voluntary free hepatitis B screening organized by the Rotary Club in 23 localities across Benin from the 20th to 28th July 2019. Rapid test for diagnostic orientation was used for the detection of HBs antigen.

RESULTS

a total of 9035 volunteers were included in the study. They were mostly of Benin origin (99%), with a mean age of 27 years; 51.1% of them were singles, mainly schoolchildren, pupils or students (37.9%). HBV seroprevalence was 6% (545/9035) [95%CI=5.5%-6.5%]. In univariate analysis, factors associated with HBs Ag colonization were: age, sex, marital status, education level, occupation and a history of diabetes, scarification and hepatitis C, while in multivariate analysis they were: sex, age and education level.

CONCLUSION

HBV seroprevalence is 6% in the study population. HBV infection mainly affects male subjects over 17 years of age with secondary-level education.

Impacts of hepatitis B and hepatitis C co-infection with tuberculosis, a prospective cohort study

BACKGROUND

This study was conducted to estimate the prevalence, determinants of hepatitis B, hepatitis C and the survival of tuberculosis patients until drug-induced hepatitis.

METHODS

Prospective cohort study design was implemented. The data were collected from September 2016 - May 2019. Systematic random sampling was used to select the study participants. Baseline data were collected before the patient starts DOTS, the sign of liver toxicity was assessed every week. Tuberculosis treatment outcomes and WHO clinical stage was recorded at the end of 6th months. Descriptive statistics were used to estimate the prevalence of hepatitis B, hepatitis C viral infections and their effect on tuberculosis treatment outcomes. Binary logistic regression was used to identify the determinants of hepatitis B and C infections. The Kaplan Meier survival curve was used to estimate the survival of tuberculosis patient and Cox regression was used to identify the predictors of drug-induced hepatitis.

RESULTS

A total of 3537 tuberculosis patients were followed. The prevalence of hepatitis B and C viral infection among tuberculosis patients were 15.1 and 17.3% respectively. Hepatitis B viral infection among tuberculosis patients was associated with alcohol, sex, HIV, chronic illness. Hepatitis C viral infection among tuberculosis patients was associated with alcohol, sex, HIV, chronic illness. The incidence density for liver toxicity among tuberculosis patients was 843/15707 person-months and liver toxicity was determined by HIV, Hepatitis B, Hepatitis C, the severity of tuberculosis and chronic illnesses.

CONCLUSION

Decision-makers should consider incorporating screening for hepatitis B and C viral infection during tuberculosis treatment.

Management of hepatitis B and hepatitis C coinfection: an expert review

INTRODUCTION

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections share common routes of transmission. HBV/HCV coinfection can lead to interactions affecting mechanisms of infection and therapy.

AREAS COVERED

In the review, we present epidemiology of HBV/HCV coinfection and current therapeutic options for both viruses. The possibility of drug-drug interactions during the treatment of coinfected patients is discussed. However, the major part of the review is dedicated to interactions between viruses and risk of HBV reactivation during HCV treatment with direct-acting antivirals (DAA). Finally, we analyze available international and national guidelines for the management of HBV reactivations related to DAA administration.

EXPERT OPINION

The most important international societies' guidelines include comments on HBV/HCV coinfection, but due to their inconsistency we present a proposal of management for HBV/HCV coinfected patients focusing mostly on HBV reactivation in patients treated for HCV. We provide some advice that should be considered in future guidelines for the management of HBV/HCV coinfection.

Epidemiology of hepatitis B and C virus infections among patients who booked for surgical procedures at Felegehiwot referral hospital, Northwest Ethiopia

Background

Hepatitis B virus(HBV) and hepatitis C virus(HCV) are the main causes of cirrhosis, liver cancer, and death. This study aimed to determine the seroprevalence and associated factors of HBV surface antigen(HBsAg) and anti-HCV among patients screened for surgery at Felegehiwot referral hospital, Northwest Ethiopia.

Methods

A hospital-based cross-sectional study was conducted among 433 patients in 2018. Data on socio-demographic and risk factors were collected by an exit interview using a pretested structured questionnaire. A venous blood sample of 5ml was collected from each participant, and serum was tested for HBsAg and anti-HCV using one-step rapid test kits and enzyme-linked immunosorbent assay. Multivariable logistic regression analysis was computed to identify factors associated with HBV and HCV infections. The odds ratio with 95%CI was used to describe the strength of association and statistical significance.

Results

A total of 422 patients gave data and included in the analysis. The mean age of patients was 36±5 years. About two-thirds, 269(64%) and 274(65%) patients were males, and from rural areas, respectively. The seroprevalence of HBsAg was 34(8%) followed by 18(4.3%) anti-HCV and 4(0.9%) co-infections. Being single(AOR = 1.96, 95%CI = 1.12–3.10), rural residence (AOR = 2.68, 95%CI = 1.28–5.61), ever heard about HBV (AOR = 2.41, 95%CI = 1.18–5.20), having multiple sexual partners(AOR = 2.85, 95%CI = 1.30–5.58), HIV positive(AOR = 3.14, 95%CI = 1.31–7.61), history of tooth extraction(AOR = 3.0, 95%CI = 1.40–6.56), hospitalization history(AOR = 2.95, 95%CI = 1.26–5.81), sharing of sharp instruments (AOR = 3.86, 95%CI = 1.82–8.79), and had blood contact(AOR = 2.64, 95%CI = 1.14–5.42) were statistically significant factors to HBV infection. Similarly, sharing of sharp instruments(AOR = 4.65, 95%CI = 1.32–15.1), tooth extraction practice(AOR = 2.81, 95%CI = 1.12–6.56), surgical history (AOR = 3.68, 95%CI = 1.64–9.82), hospitalization history(AOR = 4.51, 95%CI = 1.62–8.35) and had blood contact(AOR = 3.2, 95%CI = 1.56–8.51) were significant factors to HCV infection.

Conclusion

The seroprevalence of HBsAg and ant-HCV was high compared to WHO and previous study findings. Giving special attention to awareness creation, rural settings, improving personal behaviors, infection prevention activities of health facilities, quality of healthcare procedures is crucial to prevent viral hepatitis infection.
