Abstract
BACKGROUND HIV/HCV coinfection is associated with a rapid progression to liver damage. Specifically, NK cell population dysregulation is of particular interest, as these cells have been shown to block HCV replication effectively and have an anti-fibrogenic activity. The NKp30 receptor is linked to tumor cell lysis and has a crucial role during viral infections. In the present study, we determined the subpopulations of NK cells based on CD56 and CD16 expression, NKp30 receptor expression, its isoforms A, B, and C, along with the cytotoxicity molecules in patients with HIV/HCV. RESULTS evidenced by the APRI and FIB-4 indices, the HCV-infected patients presented greater liver damage than the HIV and HIV/HCV groups. The HCV group presented a decreased expression of NKp30 isoform A, and NK cell frequency was not different between groups; however, CD56brigth subpopulation, NKp30 receptor, and CD247 adaptor chain were decreased in HIV/HCV patients; further, we described increased levels of soluble IL-8, IL-10, IL-12, and IL-23 in the serum of HIV/HCV patients. CONCLUSIONS HCV and HIV/HCV patients have multiple parameters of non-fitness status in NK cells; awareness of these dysfunctional immunological parameters in HIV/HCV and HCV patients can elucidate possible novel therapeutics directed towards the improvement of NK cell fitness status, in order to improve their function against liver damage.

Evaluating Hepatotoxicity: A Comparative Analysis of New Generation versus Historical Antiretroviral Agents. Infect Dis Rep 2024; 16:423-434. [PMID: 38804441 PMCID: PMC11130917 DOI: 10.3390/idr16030031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 04/19/2024] [Accepted: 04/23/2024] [Indexed: 05/29/2024] Open
Abstract
(1) Background: Since the advent of zidovudine in 1987, antiretroviral therapy has undergone significant evolution, marked by the introduction of 34 antiretroviral drugs and 24 fixed-dose combinations. Despite these advances, hepatotoxicity remains a formidable challenge, influencing morbidity, mortality, and treatment adherence in HIV-infected patients. This study aims to compare the hepatotoxic effects of latest-generation antiretroviral medications with those of older-generation therapies, assessing their long-term impact on liver health in HIV patients. (2) Methods: This retrospective study analyzed data from 304 HIV patients treated with either latest-generation or older-generation antiretroviral drugs over four years. Patients were monitored for hepatotoxicity through liver function tests at diagnosis, six months, and one-year post-treatment initiation. (3) Results: Initial and six-month liver function tests showed no significant differences between the two groups. However, at one-year post-treatment, patients on latest-generation antiretrovirals exhibited significant improvements in ALT, AST, and ALP levels, suggesting a better safety profile regarding hepatotoxicity. Additionally, a significantly lower incidence of splenomegaly was observed in patients treated with newer medications. (4) Conclusions: The findings suggest that the latest-generation antiretroviral medications may offer a safer profile in terms of hepatotoxicity compared to older therapies, with potential benefits for long-term liver health. This study underscores the importance of continuous monitoring and further research to optimize ART strategies, ensuring improved patient outcomes and quality of life for individuals living with HIV.

Abstract
Lenacapavir is a novel, first-in-class, multistage inhibitor of HIV-1 capsid function approved for the treatment of multidrug-resistant HIV-1 infection in combination with other antiretrovirals for heavily treatment-experienced people with HIV. Two Phase 1, open-label, parallel-group, single-dose studies assessed the pharmacokinetics (PK) of lenacapavir in participants with moderate hepatic impairment [Child-Pugh-Turcotte (CPT) Class B: score 7-9] or severe renal impairment [15 ≤ creatinine clearance (CLcr) ≤29 mL/min] to inform lenacapavir dosing in HIV-1-infected individuals with organ impairment. In both studies, a single oral dose of 300 mg lenacapavir was administered to participants with normal (n = 10) or impaired (n = 10) hepatic/renal function who were matched for age (±10 years), sex, and body mass index (±20%). Lenacapavir exposures [area under the plasma concentration-time curve from time 0 to infinity (AUCinf) and maximum concentration (Cmax)] were approximately 1.47- and 2.61-fold higher, respectively, in participants with moderate hepatic impairment compared to those with normal hepatic function, whereas lenacapavir AUCinf and Cmax were approximately 1.84- and 2.62-fold higher, respectively, in participants with severe renal impairment compared to those with normal renal function. Increased lenacapavir exposures with moderate hepatic or severe renal impairment were not considered clinically meaningful. Lenacapavir was considered generally safe and well tolerated in both studies. These results support the use of approved lenacapavir dosing regimen in patients with mild (CPT Class A: score 5-6) or moderate hepatic impairment as well as in patients with mild (60 ≤ CLcr ≤ 89 mL/min), moderate (30 ≤ CLcr ≤ 59 mL/min), and severe renal impairment.

CD4/CD8 Ratio Recovered as a Predictor of Decreased Liver Damage in Adults Infected With HIV: 16-Year Observational Cohort Study. JMIR Public Health Surveill 2024; 10:e45818. [PMID: 37846087 PMCID: PMC10806443 DOI: 10.2196/45818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 08/23/2023] [Accepted: 10/17/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND As the life expectancy of individuals infected with HIV continues to increase, vigilant monitoring of non-AIDS-related events becomes imperative, particularly those pertaining to liver diseases. In comparison to the general population, patients infected with HIV experience a higher frequency of liver-related deaths. The CD4/CD8 ratio is emerging as a potential biomarker for non-AIDS-related events. However, few existing studies have been specially designed to explore the relationship between the CD4/CD8 ratio and specific types of non-AIDS-related events, notably liver damage. OBJECTIVE This study aimed to investigate the potential association between the CD4/CD8 ratio and the development of liver damage in a sizable cohort of patients infected with HIV receiving antiretroviral treatment (ART). Additionally, the study sought to assess the effectiveness of 3 antiretroviral drugs in recovering the CD4/CD8 ratio and reducing the occurrence of liver damage in this population. METHODS We conducted an observational cohort study among adults infected with HIV receiving ART from 2004 to 2020 in Guangxi, China. Propensity score matching, multivariable Cox proportional hazard, and Fine-Gray competing risk regression models were used to determine the relationship between the CD4/CD8 ratio recovered and liver damage. RESULTS The incidence of liver damage was 20.12% among 2440 eligible individuals during a median follow-up period of 4 person-years. Patients whose CD4/CD8 ratio did not recover to 1.0 exhibited a higher incidence of liver damage compared to patients with a CD4/CD8 ratio recovered (adjusted hazard ratio 7.90, 95% CI 4.39-14.21; P<.001; subdistribution hazard ratio 6.80, 95% CI 3.83-12.11; P<.001), findings consistent with the propensity score matching analysis (adjusted hazard ratio 6.94, 95% CI 3.41-14.12; P<.001; subdistribution hazard ratio 5.67, 95% CI 2.74-11.73; P<.001). The Efavirenz-based regimen exhibited the shortest time for CD4/CD8 ratio recovery (median 71, IQR 49-88 months) and demonstrated a lower prevalence of liver damage (4.18/100 person-years). CONCLUSIONS Recovery of the CD4/CD8 ratio was associated with a decreased risk of liver damage in patients infected with HIV receiving ART, adding evidence for considering the CD4/CD8 ratio as a potential marker for identifying individuals at risk of non-AIDS-related diseases. An efavirenz-based regimen emerged as a recommended choice for recovering the CD4/CD8 ratio and mitigating the risk of liver damage.

Abstract
OBJECTIVE Evaluating hepatic metabolic changes in people with HIV (PWH) with advanced disease, before and after antiretroviral therapy (ART) initiation, using [ 18 F]-fluorodeoxyglucose (FDG) PET-computed tomography (PET/CT). FDG PET/CT noninvasively quantifies glucose metabolism in organs. DESIGN/METHODS Forty-eight viremic PWH (CD4 + cell counts <100 cells/μl) underwent FDG PET/CT at baseline and approximately 6 weeks after ART initiation (short-term). Twenty-seven PWH participants underwent follow-up scans 2 years after treatment (long-term). FDG PET/CT scans from 20 healthy controls were used for comparison. Liver FDG uptake was quantified from the PET/CT scans. Imaging findings as well as clinical, laboratory, and immune markers were compared longitudinally and cross-sectionally to healthy controls. RESULTS Liver FDG uptake was lower at baseline and short-term in PWH compared with controls ( P < 0.0001). At the long-term scan, liver FDG uptake of PWH increased relative to baseline and short-term ( P = 0.0083 and 0.0052) but remained lower than controls' values ( P = 0.004). Changes in FDG uptake correlated negatively with levels of glucagon, myeloperoxidase, sCD14, and MCP-1 and positively with markers of recovery (BMI, albumin, and CD4 + cell counts) ( P < 0.01). In multivariable analyses of PWH values across timepoints, BMI and glucagon were the best set of predictors for liver FDG uptake ( P < 0.0001). CONCLUSION Using FDG PET/CT, we found decreased liver glucose metabolism in PWH that could reflect hepatocytes/lymphocytes/myeloid cell loss and metabolic dysfunction because of inflammation. Although long-term ART seems to reverse many hepatic abnormalities, residual liver injury may still exist within 2 years of treatment initiation, especially in PWH who present with low nadir CD4 + cell counts.

Abstract
Physiologically based pharmacokinetic (PBPK) models have gained in popularity in the last decade in both drug development and regulatory science. PBPK models differ from classical pharmacokinetic models in that they include specific compartments for tissues involved in exposure, toxicity, biotransformation, and clearance processes connected by blood flow. This study aimed to address the gaps between the mathematics and pharmacology framework observed in the literature. These gaps included nonconserved systems of equations and compartment concentration that were not biologically relatable to the tissues of interest. The resulting system of nonlinear differential equations is solved numerically with various methods for benchmarking and comparison. Furthermore, a sensitivity analysis of all parameters were conducted to elucidate the critical parameters of the model. The resulting model was fit to clinical data as a performance benchmark. The clinical data captured the second line of antiretroviral treatment, lopinavir and ritonavir. The model and clinical data correlate well for coadministration of lopinavir/ritonavir with rifampin. Drug-drug interaction was captured between lopinavir and rifampin. This article provides conclusions about the suitability of physiologically based pharmacokinetic models for the prediction of drug-drug interaction and antiretroviral and anti-TB pharmacokinetics.

Markers of Immune Activation and Inflammation Are Associated with Higher Levels of Genetically-Intact HIV in HIV-HBV Co-Infected Individuals. J Virol 2022; 96:e0058822.

Abstract
Co-infection with hepatitis B (HBV) and human immunodeficiency virus (HIV) increases overall and liver-related mortality. In order to identify interactions between these two viruses in vivo, full-length HIV proviruses were sequenced from a cohort of HIV-HBV co-infected participants and from a cohort of HIV mono-infected participants recruited from Bangkok, Thailand, both before the initiation of antiretroviral therapy (ART) and after at least 2 years of ART. The co-infected individuals were found to have higher levels of genetically-intact HIV proviruses than did mono-infected individuals pre-therapy. In these co-infected individuals, higher levels of genetically-intact HIV proviruses or proviral genetic-diversity were also associated with higher levels of sCD14 and CXCL10, suggesting that immune activation is linked to more genetically-intact HIV proviruses. Three years of ART decreased the overall level of HIV proviruses, with fewer genetically-intact proviruses being identified in co-infected versus mono-infected individuals. However, ART increased the frequency of certain genetic defects within proviruses and the expansion of identical HIV sequences. IMPORTANCE With the increased availability and efficacy of ART, co-morbidities are now one of the leading causes of death in HIV-positive individuals. One of these co-morbidities is co-infection with HBV. However, co-infections are still relatively understudied, especially in countries where such co-infections are endemic. Furthermore, these countries have different subtypes of HIV circulating than the commonly studied HIV subtype B. We believe that our study serves this understudied niche and provides a novel approach to investigating the impact of HBV co-infection on HIV infection. We examine co-infection at the molecular level in order to investigate indirect associations between the two viruses through their interactions with the immune system. We demonstrate that increased immune inflammation and activation in HBV co-infected individuals is associated with higher HIV viremia and an increased number of genetically-intact HIV proviruses in peripheral blood cells. This leads us to hypothesize that inflammation could be a driver in the increased mortality rate of HIV-HBV co-infected individuals.

Abstract
BACKGROUND Comprehensively estimating the impacts of HIV-1 subtype diversity on long-term clinical outcomes during antiretroviral therapy (ART) can help inform program recommendations. METHODS The HIV-1 sequence data and clinical records of 5950 patients from all 14 prefectures in Guangxi, China, during 2008-2020 were included. Evolutional trends of CD4+ T-lymphocyte count and viral load were explored, and the effects of HIV-1 subtypes on clinical outcomes were estimated by the Cox proportional hazards model. The polymorphisms involved in drug resistance mutation were analyzed. RESULTS Compared with patients with CRF07_BC, patients with CRF01_AE and CRF08_BC showed poor immunologic and virologic responses to antiretroviral therapy. Although the median expected time from ART initiation to virologic suppression for all patients was approximately 12 months, patients with CRF01_AE and CRF08_BC had a long time to achieve immune recovery and a short time to occur immunologic failure, compared with patients with CRF07_BC. Adjusted analysis showed that both CRF01_AE and CRF08_BC were the negative factors in immune recovery and long-term mortality. In addition, CRF08_BC was a negative factor in virologic suppression and a risk factor of virologic failure. This poor virologic response might result from the high prevalence of drug resistance mutation in CRF08_BC. CONCLUSIONS Compared with patients with CRF07_BC, patients with CRF01_AE could benefit more from immediate ART, and patients with CRF08_BC are more suitable for PI-based regimens. These data emphasize the importance of routine HIV-1 genotyping before ART, immediate ART, and personalized ART regimens to improve the prognosis for patients undergoing ART.

Abstract
OBJECTIVES The study aimed to investigate the incidence of and risk factors for liver damage in patients with human immunodeficiency virus type-1 (HIV-1) mono-infection receiving antiretroviral therapy (ART). METHODS We retrospectively analyzed the clinical data of patients who were diagnosed with HIV-1 infection and initiated ART from January to December 2017. Among them, 382 patients with HIV-1 mono-infection and normal baseline liver function were included in the analysis. The incidence of liver damage at each follow-up point, and possible risk factors for liver damage were evaluated via COX regression survival analyses. RESULTS The overall incidence of liver damage (grade I-IV) was 27.23% (interquartile range [IQR]: 26.38%-28.72%). Grade I liver damage was most common and accounted for 22.13% of cases (IQR: 21.06%-24.04%), while grade II liver damage accounted for 3.40% of cases (IQR: 3.19%-4.26%). COX regression and survival analyses revealed that baseline body mass index (BMI), alanine aminotransferase (ALT) level, CD4+ T cell count, HIV-1 viral load, and the antiretroviral regimen were significantly correlated with the occurrence of liver damage. Moreover, baseline ALT levels and HIV-1 viral load were identified as independent risk factors for liver damage in patients with HIV-1 mono-infection. CONCLUSION Liver damage is common in patients with HIV-1 mono-infection undergoing ART. Patients with risk factors for liver damage should be well-informed before the initiation of ART, and liver function should be closely monitored during ART even in patients with normal liver function before ART.

Front Med (Lausanne) 2022; 9:817370. [PMID: 35273978 PMCID: PMC8901992 DOI: 10.3389/fmed.2022.817370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Accepted: 01/31/2022] [Indexed: 12/04/2022] Open
Abstract
Background: This study investigated the factors correlated with severe liver damage among HIV-infected inpatients. Methods: We retrospectively collected the first hospitalized HIV-infected patients in the Department of Infectious Disease of the First Affiliated Hospital of China Medical University from January 1, 2010, to December 31, 2019. We used multivariate logistic regression to identify the factors associated with severe liver damage. Results: A total of 493 patients with abnormal liver tests were recruited. Among 63 cases (12.8%) with severe liver injury, drug-induced liver injury (DILI) identified by the updated Roussel Uclaf Causality Assessment Method (RUCAM) score as the direct cause was found in 43 cases. Anti-tuberculosis drug (ATD) exposure [adjusted odds ratio (aOR) = 1.835, 95% confidence interval (CI): 1.031–3.268], cotrimoxazole exposure (aOR = 2.775, 95% CI: 1.511–5.096), comorbidity of viral hepatitis (aOR = 2.340, 95% CI: 1.161–4.716), alcohol consumption history (aOR = 2.392, 95% CI: 1.199–4.769), and thrombocytopenia (aOR = 2.583, 95% CI:1.127–5.917) were associated with severe liver injury (all P < 0.05). Conclusions: DILI was the predominant cause of severe liver damage, followed by hepatitis virus co-infection. For patients with alcohol consumption and thrombocytopenia, frequent monitoring of liver function tests should be considered.

Abstract
PURPOSE OF REVIEW To date, more than 30 antiretroviral drugs have been approved by the Food and Drug Administration for the treatment of HIV infection. As new drugs with better efficacy and safety profile become available for clinical practice, older drugs are either withdrawn from the market or become no longer actively prescribed. We review hepatotoxicity associated with contemporary antiretroviral drugs, with emphasis on data from the past 3 years. RECENT FINDINGS Although less robust data exists for side effects of contemporary antiretroviral medications recently approved for the management of HIV (i.e., doravirine, ibalizumab, fostemsavir, cabotegravir), the risks of substantial hepatotoxicity appears to be minimal with these agents. SUMMARY Although newer antiretroviral drugs are better tolerated than their earlier counterparts, they are not completely devoid of adverse drug reactions, including hepatotoxicity. Monitoring patients on antiretroviral therapy for treatment-emergent liver injury should continue to be part of routine clinical care.

Abstract
Introducción. Para prevenir el desarrollo de enfermedad hepática crónica en pacientes con VIH durante la Terapia Antirretroviral de Gran Actividad (TARGA) se deben estimar y monitorear cambios en el perfil hepático.
Objetivo. Determinar la variación de las concentraciones del perfil hepático en pacientes con VIH durante la TARGA.
Materiales y métodos. Estudio retrospectivo longitudinal realizado en 100 pacientes con VIH atendidos en el Hospital Nacional Hipólito Unanue, Lima, Perú, entre 2015 y 2017. Se incluyeron pacientes en todos los estadios de infección clínica que estuvieran recibiendo TARGA y en los que se contara con resultados del perfil hepático para alanina aminotransferasa (ALT), aspartato aminotransferasa (AST), fosfatasa alcalina (FA), Gammaglutamiltranspeptidasa (GGT), y proteínas totales (PT). Se realizaron tres análisis de control de la función hepática (cada 3 meses) durante la TARGA y los participantes se agruparon en niveles normales y elevados para todos los marcadores hepáticos. Las diferencias entre las muestras analizadas fueron determinadas mediante la prueba t de Student para muestras relacionadas, con un intervalo de confianza de 95% y un nivel de significancia de p<0.05.
Resultados. La edad promedio fue de 33±9.56 años y el 67% fueron varones. Los valores séricos promedio de AST, ALT, y FA disminuyeron entre la primera y la tercera medición (p=0.021, p=0.076, y p=0.002, respectivamente). No se observaron diferencias significativas en los niveles de GGT y PT entre las tres mediciones, ni entre los pacientes con valores normales y elevados para AST, ALT, FA y PT, pero sí para GGT (p=0.010).
Conclusiones. Se observaron variaciones en los niveles de los marcadores hepáticos de todos los participantes, con una tendencia a la reducción en AST, ALT y FA entre las etapas iniciales y finales de la terapia, lo que implica que la TARGA podría ejercer un rol en el daño tisular hepático.

Abstract
Contemporary antiretroviral agents afford enhanced potency and safety for patients living with HIV. Newer antiretroviral drugs are often better tolerated than those initially approved in the early stages of the HIV epidemic. While the safety profile has improved, adverse drug reactions still occur. We have segregated the antiretroviral agents used in contemporary practice into class groupings based on their mechanism of antiviral activity (non-nucleoside reverse transcriptase inhibitors, nucleoside reverse transcriptase inhibitors, integrase inhibitors, protease inhibitors, and entry inhibitors) while providing a review and discussion of the hepatoxicity seen in the most relevant clinical literature published to date. Clinical literature for individual agents is discussed and agent comparisons afforded within each group in tabular format. Our review will provide a summative overview of the incidence and medications associated with hepatic adverse reactions linked to the use of contemporary antiretroviral drugs.

Abstract
Coronavirus disease 2019 is a pandemic disease caused by a novel RNA coronavirus, SARS coronavirus 2 (SARS-CoV-2), which is implicated in the respiratory system. SARS-CoV-2 also targets extrapulmonary systems, including the gastrointestinal tract, liver, central nervous system and others. SARS-CoV-2, like other RNA viruses, targets the liver and produces liver injury. This literature review showed that SARS-CoV-2-induced liver injury is different from other RNA viruses by a transient elevation of hepatic enzymes and does not progress to liver fibrosis or other unfavorable events. Moreover, SARS-CoV-2-induced liver injury usually occurs in the presence of risk factors, such as nonalcoholic liver fatty disease. This review highlights the important differences between RNA viruses inducing liver injury taking into consideration the clinical, biochemical, histopathological, postmortem findings and the chronicity of liver injury that ultimately leads to liver fibrosis and hepatocellular carcinoma.

Abstract
The aim of this study was to develop and externally validate a simple-to-use nomogram for predicting the survival of hospitalised human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients (hospitalised person living with HIV/AIDS (PLWHAs)). Hospitalised PLWHAs (n = 3724) between January 2012 and December 2014 were enrolled in the training cohort. HIV-infected inpatients (n = 1987) admitted in 2015 were included as the external-validation cohort. The least absolute shrinkage and selection operator method was used to perform data dimension reduction and select the optimal predictors. The nomogram incorporated 11 independent predictors, including occupation, antiretroviral therapy, pneumonia, tuberculosis, Talaromyces marneffei, hypertension, septicemia, anaemia, respiratory failure, hypoproteinemia and electrolyte disturbances. The Likelihood χ2 statistic of the model was 516.30 (P = 0.000). Integrated Brier Score was 0.076 and Brier scores of the nomogram at the 10-day and 20-day time points were 0.046 and 0.071, respectively. The area under the curves for receiver operating characteristic were 0.819 and 0.828, and precision-recall curves were 0.242 and 0.378 at two time points. Calibration plots and decision curve analysis in the two sets showed good performance and a high net benefit of nomogram. In conclusion, the nomogram developed in the current study has relatively high calibration and is clinically useful. It provides a convenient and useful tool for timely clinical decision-making and the risk management of hospitalised PLWHAs.

Abstract
In an era of improved survival due to modern antiretroviral therapy, liver disease has become a major cause of morbidity and mortality, resulting in death in 15-17% of human immunodeficiency virus (HIV)-infected patients. Alcohol enhances HIV-mediated liver damage and promotes the progression to advanced fibrosis and cirrhosis. However, the mechanisms behind these events are uncertain. Here, we hypothesize that ethanol metabolism potentiates accumulation of HIV in hepatocytes, causing oxidative stress and intensive apoptotic cell death. Engulfment of HIV-containing apoptotic hepatocytes by non-parenchymal cells (NPCs) triggers their activation and liver injury progression. This study was performed on primary human hepatocytes and Huh7.5-CYP cells infected with HIV-1ADA, and major findings were confirmed by pilot data obtained on ethanol-fed HIV-injected chimeric mice with humanized livers. We demonstrated that ethanol exposure potentiates HIV accumulation in hepatocytes by suppressing HIV degradation by lysosomes and proteasomes. This leads to increased oxidative stress and hepatocyte apoptosis. Exposure of HIV-infected apoptotic hepatocytes to NPCs activates the inflammasome in macrophages and pro-fibrotic genes in hepatic stellate cells. We conclude that while HIV and ethanol metabolism-triggered apoptosis clears up HIV-infected hepatocytes, continued generation of HIV-expressing apoptotic bodies may be detrimental for progression of liver inflammation and fibrosis due to constant activation of NPCs.
