Hepatitis B and C infections in HIV-1 patients on combination antiretroviral therapy (cART) in Ghana: implications for immunologic recovery, clinical response to treatment, and hepatotoxicity

The Impact of Hepatitis B and/or C on Liver Function and on the Response to Antiretroviral Therapy in HIV-Infected Patients: A Romanian Cohort Study

Background: Hepatitis B (HBV) and C (HCV) virus coinfections remain major contributors to liver-related morbidity and mortality among people living with HIV (PLWH). This study aimed to assess the prevalence of HBV and/or HCV coinfections in a Romanian HIV cohort and to evaluate their impact on immunological, virological, and liver function parameters under antiretroviral therapy (ART). Methods: We retrospectively analyzed 462 HIV-infected patients (2018-2021) from the National Institute of Infectious Diseases, Bucharest, stratified into four groups: HIV mono-infection (n = 176), HIV/HBV (n = 114), HIV/HCV (n = 97), and HIV/HBV/HCV (n = 75) coinfections. Immunological (CD4 count, CD8 count, and CD4/CD8 ratio), virological (HIV-1 RNA), and hepatic parameters (ALT, AST, GGT, bilirubin, amylase, and lipase) were compared. Results: No significant differences were observed between groups regarding the immune recovery (mean CD4 count p = 0.89, HIV-RNA suppression p = 0.78). However, liver and pancreatic parameters showed statistically significant deterioration in the coinfected groups. ALT (p < 0.001), GGT (p = 0.009), total bilirubin (p = 0.011), amylase (p = 0.010), and lipase (p < 0.001) were significantly higher in the triple-infection (HIV/HBV/HCV) group compared to HIV mono-infected patients. Coinfection was also associated with a longer duration of illness (p = 0.002) and therapy (p = 0.021) and with a higher number of ART regimens used (p = 0.013). Conclusions: While HIV suppression and immune recovery were not significantly impaired by HBV/HCV coinfections, liver and pancreatic injuries were significantly more prevalent and severe in coinfected patients. Regular monitoring of hepatic function and integrated management strategies are recommended to minimize liver-related complications in this population.

Prevalence of Hepatitis C viral infection in Ghana: A systematic review and meta-analysis protocol

Background Hepatitis C virus (HCV) infection remains a major public health concern for many countries. A recent survey report in Ghana revealed a national HCV prevalence rate of 4.6% in a population of 35 million but with notably higher regional variations ranging from 8.6 to 14.4%. Considering that Ghana is targeting micro-elimination of HCV as part of the STOP Hepatitis C project, it is prudent to estimate the current epidemiological burden of hepatitis C for evidence-based policymaking, public health research, and program direction. An initial search of the literature showed a previous review that spanned from 1995 to 2015. The gap of almost 10 years may not reflect the current burden of hepatitis C in Ghana, hence this review. A systematic literature search will be performed in the major electronic databases and search engines including PubMed, Embase, Web of Science, CINAHL, and African Journals Online (AJOL). There will be a search for articles reporting on the prevalence of hepatitis C in Ghana from 2016 to 2024 in these databases. The protocol is registered with PROSPERO (CRD42024592505).

Correlates of internalized stigma and antiretroviral therapy adherence among people living with HIV in the Volta region of Ghana

OBJECTIVE

HIV-related stigma is a major public health concern compromising the rights and health outcomes of many people living with HIV (PLWH). Its reduction is said to be critical in strengthening the continuous efforts targeted at preventing and controlling HIV, as it directly impacts antiretroviral treatment adherence. This study examines the association between HIV-related stigma and adherence to antiretroviral therapy (ART) among PLWH in one of the 16 administrative regions of Ghana, Africa.

METHODS

This descriptive cross-sectional study employed a survey to assess the factors affecting the utilization of ART among PLWH (n = 155) in the Volta region. The Center for Support Evaluation adherence index and internalized stigma of AIDS Tool were used to collect data on medication adherence and stigma, respectively. Data was analyzed using R statistical analysis software. Logistic regression models were performed to ascertain the predictors of ART utilization among PLWH.

RESULTS

A greater proportion (70%) of the study's participants reported adherence to ART. We found a positive association between HIV-related internalized stigma and medication adherence such that reporting high levels of stigma on average was associated with high levels of medication adherence [OR = 1.08, 95% CI:1.01, 1.15]. Older age was related to higher adherence while reporting more depressive symptoms was associated with low medication adherence.

CONCLUSION

Our findings show that stigma may serve as a facilitator instead of a barrier to adhering to antiretroviral medication. Although this contradicts common narratives about stigma's destructive effect, it is possible to promote good health-seeking behavior when the fear component of stigma is considered. To encourage medication adherence towards meeting UNAIDS' 95-95-95 agenda and better understand stigma's role, further research is required.

Prevalence of occult hepatitis B infection among treatment-naive persons living with HIV in Ghana

Hepatitis B virus (HBV) constitutes a significant global health challenge, with more than 2 billion people infected globally and almost 291 million chronic cases. In Africa, coinfection of HBV with Human Immunodeficiency Virus (HIV) is high, yet the condition remains overlooked in many countries. While antiretroviral therapy (ART) has improved HIV survival, viral hepatitis continues to contribute to morbidity and mortality. Occult Hepatitis B infection (OBI), characterized by a low-level of HBV DNA in individuals with negative hepatitis B surface antigen (HBsAg), is an emerging concern among HIV seropositive individuals due to the risk of HBV reactivation and associated complications, especially hepatocellular carcinoma (HCC). Ghana has an estimated HBV/HIV coinfection prevalence of 13.6% making it important to also determine potential cases of OBI. This study aims to assess OBI prevalence in persons living with HIV (PLHIV). A cross-sectional study was conducted in five health facilities in the Cape Coast Metropolis. HBV-related serological markers were determined among 116 PLHIV using the Enzyme-Linked Immunosorbent Assay (ELISA) method. HBV DNA was extracted from 30 participants found to be HBsAg negative but positive for hepatitis B core antibody (HBcAb+). Nested PCR was employed in detecting HBV DNA and HBV viral load was performed using qPCR. The median age of the participants was 37 years (IQR 22-65). Serologically, 7.8% (n = 9, 95% CI: 3.5-22.7), 12.1% (n = 14), and 25.9% (n = 30) tested positive for solely HBsAg, HBsAb, and HBcAb respectively. OBI prevalence among HBsAg-/HBcAb+ participants was 16.7% (n = 5, 95% CI: 6.5-23.7) with a median HBV DNA level of 139.2 IU/ml (IQR, 96.7-142.0). The prevalence of OBI among HIV-positive participants in the Cape Coast Metropolis highlights the need to consider screening for HBV among HIV patients using nucleic acid amplification tests. This can inform medical management and reduce the risk of liver complications, including HCC.

Tenofovir disoproxil fumarate mediates neuronal injury by inducing neurotoxicity

PURPOSE

Highly active antiretroviral therapy (HAART) is an accepted treatment option for patients with virus infection. Mounting evidence indicated that persistent HAART treatment is implicated with increased morbidity of HIV-associated neurocognitive disorders (HAND) in patients. Tenofovir disoproxil fumarate (TDF), a novel nucleotide reverse transcriptase inhibitor (NRTI), was used in patients with HIV co-infected with HBV. And it is still a vital first-line antiretroviral compounds in HAART. However, whether persistent treatment with TDF is involved in HAND development remains to be further elucidated. In this study, we aimed to discuss the neurotoxicity of TDF.

METHODS

We used SH-SY5Y cells and primary neuronal cells to evaluate the neurotoxicity of TDF in vitro. The cytotoxicity of TDF on SH-SY5Y cells and primary neuronal cells was evaluated by the cell viability and LDH levels by MTT assay and LDH kit, respectively. Hoechst 33342 staining, TUNEL assay and flow cytometry were performed to evaluate the cells apoptosis. The intracellular reactive oxygen species (ROS) and malondialdehyde (MDA) production were measured by commercial kits. In addition, the activation level of caspase-3 was evaluated using spectrophotometry and western blotting.

RESULTS

Our results showed that TDF treatment significantly induced cell viability and induced apoptosis of SH-SY5Y cells and primary neuronal cells. Furthermore, the ROS levels and MDA productions were significantly up-regulated in nerve cells treated with TDF.  CONCLUSION: Our findings indicated that TDF may induce neuronal cell apoptosis through increasing the intracellular ROS and the expression level of caspase-3, which may be related to the increasing prevalence of HAND.

Failure to seroconvert after three doses of inactivated COVID-19 vaccines in a patient co-infected with HBV and HIV: A case report

In the global context of the COVID-19 pandemic, the overall benefits of getting any COVID-19 vaccine approved by the World Health Organization for emergency use outweigh the potential risks, even in people with weakened immune systems, including people living with HIV (PLWH). At present, there are no reports of HIV/hepatitis B virus (HBV) co-infected patients receiving a booster dose of the inactivated COVID-19 vaccine. Here, we describe a patient with HIV/HBV co-infection who did not seroconvert to three doses of the inactivated COVID-19 vaccine.

Evaluation of Clinical Biomarkers Related to CD4 Recovery in HIV-Infected Patients—5-Year Observation

Human Immunodeficiency Virus infection leads to the impairment of immune system function. Even long-term antiretroviral therapy uncommonly leads to the normalization of CD4 count and CD4:CD8 ratio. The aim of this study was to evaluate possible clinical biomarkers which may be related to CD4 and CD4:CD8 ratio recovery among HIV-infected patients with long-term antiretroviral therapy. The study included 68 HIV-infected patients undergoing sustained antiretroviral treatment for a minimum of 5 years. Clinical biomarkers such as age, gender, advancement of HIV infection, coinfections, comorbidities and applied ART regimens were analyzed in relation to the rates of CD4 and CD4:CD8 increase and normalization rates. The results showed that higher rates of CD4 normalization are associated with younger age (p = 0.034), higher CD4 count (p = 0.034) and starting the therapy during acute HIV infection (p = 0.012). Higher rates of CD4:CD8 ratio normalization are correlated with higher CD4 cell count (p = 0.022), high HIV viral load (p = 0.006) and acute HIV infection (p = 0.013). We did not observe statistically significant differences in CD4 recovery depending on gender, HCV/HBV coinfections, comorbidities and opportunistic infections. The obtained results advocate for current recommendations of introducing antiretroviral therapy as soon as possible, preferably during acute HIV infection, since it increases the chances of sufficient immune reconstruction.

Factors Associated with Liver Enzyme Abnormalities in HIV-HBV and/or HCV Co-infected Patients in Kinshasa, Democratic Republic of the Congo: Multicenter Cross-sectional Study

BACKGROUND AND OBJECTIVE

Liver enzyme abnormalities (LEA) are extremely common and sometimes severe in individuals infected with human immunodeficiency virus (HIV), but data for this disorder are lacking in the developing countries. The objective of this study was to identify factors associated with LEA in HIV-hepatitis B virus (HBV)/hepatitis C virus (HCV) co-infected patients in Kinshasa, Democratic Republic of the Congo.

METHODS

This cross-sectional analytical study included 180 people living with HIV (PLWHIV) mono-infected or co-infected with HBV/HCV between November 10, 2013 and January 10, 2014 in Kinshasa. Sociodemographic, clinical, biological, serological, and immunological data were analyzed. Levels of serum glutamate oxaloacetate transferase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were determined. Antibody levels were determined using enzyme-linked immunosorbent assay (ELISA).

RESULTS

The mean age of patients was 44.2±11.0 years; female sex was predominant (76.7%). Co-infection, mainly with HBV, but also HCV, was found in 43 (23.9%) patients. Elevated liver enzymes were found in 77 (42.8%) of the patients. No difference was found in the rate of liver enzyme abnormalities between patients with HIV mono-infection or HIV co-infection (46.7% versus 30.2%, respectively; P=0.08). Factors associated with LEA were age ≥50 years (adjusted odds ratio [OR] 2.7; 95% CI 1.4-5.5), duration of HIV infection >3 years (adjusted OR 2.7; 95% CI 1.4-5.5), and CD4 T cells count ≤303 cells/mm3 (adjusted OR 2.2; 95% CI 1.1-4.5).

CONCLUSIONS

Liver enzyme abnormalities are frequent in patients co-infected with HIV-HBV/HCV as well as in HIV patients without co-infection. Diagnosis is determined based on age, immunodeficiency, and length of illness.
