Prevalence and risk factors for hepatitis C virus, hepatitis B virus, and human immunodeficiency virus in transfused children in Kinshasa

Prevalence of hepatitis B and C viral co-infection and associated factors with HIV infection in children in South Kivu, Democratic Republic of the Congo

BACKGROUND

The World Health Organization's (WHO) 2030 goal of eradicating Hepatitis B and C viruses must also include HIV co-infected children. However, data on the prevalence of this condition are lacking in the Democratic Republic of Congo (DRC), which is considered as one of the countries with high-prevalence of these viruses. The need to assess the extent of this co-infection in the children of this country is therefore important in order to capitalize on efforts to improve prevention and management of both infections.

METHODOLOGY

This is a comparative cross-sectional study conducted from February 04, 2015 to September 03, 2019 at 14 General Reference Hospitals with a pediatric HIV management programme in South Kivu province. The study compared the frequency of hepatitis B (HBV) and C (HCV) markers and factors associated with these two viruses in two equal groups: HIV-positive and HIV-negative children. The data were analyzed using the SPSS version 20.0 software and the significance level was set at p-value less than 0.05.

RESULTS

The study involved a total of 594 children, 297 of whom were HIV-positive and 297 negative. HBsAg was found in 8.7% of HIV-positive patients and 0.7% for HCV antibodies. On the other hand, among the HIV-negative patients, the proportion of HBsAg was 0.7% but no cases with anti-HCV antibodies were detected. HIV status increases by 14 times the risk of co-occurring with HBV [OR 14.1 (95% CI: 3.33-60.2); p < 0.001] and this risk is not apparent for HCV (p = 0.297). Multivariate logistic regression showed that history of jaundice in the family (aOR:4.19;95% CI: 2.12-11.59), recent hospitalization (aOR:10.7;95% CI: 6.69-17.2), surgery (aOR: 3.24;95% CI: 1.18-8.92), piercing (aOR: 4.26;95% CI: 1.70-10.7) and transfusion in the last 6 months (aOR: 2.69;95% CI: 1.55-4.67) were significantly associated with higher risk of being HBV- HIV co-infected.

CONCLUSION

This study investigated the importance of hepatitis viral co-infections in HIV-positive children in South Kivu. Particular attention should be paid to prevention and early detection of these co-infections in this population.

Hepatitis B infection and risk factors among children living with HIV in Yaounde, Cameroon: an integrated management

Background

The endemicity of hepatitis B virus (HBV) prompted the systematic immunization of newborns in Cameroon since 2005. In the frame of a considerable burden of HIV/HBV co-infection (17.5%), monitoring HBV among children living with HIV (CLHIV) would guide toward HIV/HBV integrated paediatric care. We sought to ascertain the prevalence and determinants of HBV infection in the population of CLHIV and performance of commonly used rapid diagnosis tests (RDTs).

Methods

Cross-sectional study conducted from February through June 2017 in a subset of CLHIV ≤15 years old at the Essos Hospital Centre, Yaounde, Cameroon. HBV was tested by HBsAg ELISA sandwich in duplicates for each sample, and the mean optical density was calculated. The Determinants of HBV-prevalencewere evaluated, and p < 0.05 was the significance threshold. The performance of two HBV RDTs (Diaspot vs. HBV-5) was evaluated in comparison to ELISA (used as gold standard).

Results

Of the 83 CLHIV enrolled (54.2% female, mean age 8.7 [±3.8] years, 60% vaccinated against HBV, all breastfed), HBV-prevalence was 2.41% (2/83). HBV-positivity was significantly associated with unknown maternal HBV status (2.9% [2/69] vs. 0.0% [0/14], p = 0.0097) and vaginal delivery (2.4% [2/82] vs. 0.0% [0/1], p = 0.0018). Moreover, the most likely to be positive were aged 11 and 15 years, and had experienced neither anti-HBV vaccination nor anti-HBV serum administration, and both had not been treated with any antiseptic solution at birth. Regarding the performance of Diaspot vs. HBV-5 respectively, sensitivity was 100% (2/2) vs. 50% (1/2), while specificity was 100% (45/45) vs. 97.8% (44/45); positive and negative predictive values of Diaspot versus HBV-5 were respectively 100% (2/2) and 100% (45/45) versus 50% (1/2) and 97.8% (44/45).

Conclusion

HBV-infection in the population of CLHIV appears at a moderate prevalence, suggesting a decreased burden likely due to preventive measures including the wide vaccine coverage. Focusing on mothers with unknown HBV status and promoting safer delivery mode (caesarean section) for HBV-positive motherswould contribute toward pediatric HBV elimination. In context of limited resources, Diaspot test appears more reliable to rollout HBV-infection in the population of CLHIV. As findings are limited to a small sample size, studies on a wider population would be relevant.

Systematic review and meta-analysis of hepatitis C virus infection in the Democratic Republic of Congo

OBJECTIVES

Hepatitis C virus (HCV) infection is endemic in the Democratic Republic of the Congo (DRC), where the prevalence of HCV antibodies (anti-HCV) is reported to range from 0.2% to 13.7%. However, the reported prevalence rates have been inconsistent. Therefore, a meta-analysis of observational studies was conducted to provide updates on the prevalence of HCV infection in the DRC.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

Medline, EMBASE and Google Scholar were searched for publications reporting on HCV infection in the DRC up to autumn 2015. In addition, a manual search was undertaken to detect relevant papers. Studies performed in groups at low risk of HCV (blood donors and pregnant women) were used for the meta-analysis. The random effects model was used to estimate the pooled prevalence of anti-HCV.

RESULTS

Sixteen studies with 13,799 participants (aged 6 months-71 years) met the inclusion criteria. The studies were performed in blood donors, pregnant women, military personnel, individuals with human immunodeficiency virus, children, commercial sex workers, Congolese patients living in Canada, patients with sickle cell disease and hospitalized patients. The reviewed studies revealed the presence of anti-HCV in almost all studied age groups and did not differ between sexes. The pooled prevalence of anti-HCV was 2.9% [95% confidence interval 1.5-4.3%]. Subgroup analyses revealed that the prevalence rates of anti-HCV in blood donors and pregnant women were 2.7% (95% confidence interval: 1.1-4.4%) and 3.3% (1.4-5.1%), respectively.

CONCLUSIONS

HCV infection remains an issue of public concern in the DRC, demonstrating a need for adequate hepatitis control programmes. Efforts must be made to virtually eliminate transfusion-transmitted HCV throughout the country.

Seroprevalence of CMV, HSV-2 and HBV among HIV-Infected Malawian Children: A Cross-sectional Survey

BACKGROUND

Little is known about viral co-infections in African human immunodeficiency virus (HIV)-infected children. We examined the prevalence of seromarkers for cytomegalovirus (CMV), herpes simplex virus type 2 (HSV-2) and hepatitis B virus (HBV) infections among HIV-infected, antiretroviral treatment (ART)-naïve children in Lilongwe, Malawi.

METHODS

Ninety-one serum samples were tested for IgG and IgM antibodies to CMV, and IgG antibodies to HSV-2 and hepatitis B surface antigen (HBsAg). Baseline demographic, clinical and laboratory data were abstracted from electronic records.

RESULTS

CMV IgG was the most common positive result in all age groups (in 73% of children <1 year, and 100% in all other groups). Three patients were CMV IgM positive (3.3%), suggesting acute infection. HSV-2 IgG was positive in four patients (4.4%), and HBsAg in two (2.2%).

CONCLUSIONS

CMV infection occurred early in life, and few children had specific signs of CMV infection at the time of ART initiation. Unrecognized HBV infection represents opportunities for testing and treatment of HIV/HBV co-infected children.

Seroprevalence of hepatitis B and C viruses and risk factors in HIV infected children at the Felgehiwot referral hospital, Ethiopia

BACKGROUND

Liver hepatitis due to Hepatitis B (HBV) and hepatitis C virus (HCV) co-infection is the leading cause of morbidity and mortality in HIV infected children and it is more severe in resource poor settings. Data on seroprevalence of HBV and HCV among HIV infected children are scarce in Ethiopia. This study was conducted to determine seroprevalence and risk factors of HBV and HCV and its effect on liver enzyme among HIV-positive children aged 18 months to 15 years attending the paediatric HIV care and treatment clinic at Felege Hiwot referral hospital, Ethiopia.

METHODS

A cross-sectional study was conducted in May, 2014. Demographic and risk factors were collected using a structured questionnaire. Hepatitis B surface antigen (HBsAg) and anti-HCV antibodies were detected using an enzyme linked immunosorbent assay (ELISA). Alanine aminotransferase (ALT) levels were determined. The results were analyzed using descriptive and logistic regression.

RESULTS

A total of 253 HIV positive children, boys (52.5%) and girls (47.5%) took part in the study. The median age of the children was 11 years. Overall, 19 (7.5%) of HIV infected children were positive either for HBsAg or anti-HCV antibodies. The seroprevalence of HBV and HCV were 2.0% and 5.5%, respectively. All HBsAg positive children were in older age groups (11-15 years). Seroprevalence of HCV was higher in children from urban (7.7%) than rural (1.2%) residents (P=0.02). Overall, 29 (12.1%) of children had elevated ALT. Of these, 31.5% were from HBsAg or anti-HCV antibody positive children whereas 9.8% were from hepatitis B or C virus negative children (P=0.001). Multivariate logistic regression showed that being positive for HBsAg or anti-HCV antibody (AOR: 4.7(95% CI: 1.5-13.5) was significantly associated with elevated ALT.

CONCLUSION

HBV and HCV co-infections are common in HIV positive children. In HIV positive children, HBV and HCV co-infection were associated with elevate ALT. Routine screening for HBV and HCV in HIV infected children should be implemented.
