Effect of SARS-CoV-2 infection on the liver

Effect of SARS-CoV-2 infection on liver function in patients with hepatitis B

OBJECTIVE

To investigate the impact of SARS-CoV-2 infection on liver function and prognosis in patients with HBV infection.

METHODS

A total of 154 HBV-positive patients (HBV ( +) group) and 154 HBV-negative patients (HBV (-) group) diagnosed with COVID-19 at Taizhou Hospital between December 10, 2022, and January 31, 2023, were included in this study. Clinical characteristics, treatment, and laboratory findings were collected from patients at three time points: before (T1), during (T2), and at the time of discharge (T3) from SARS-CoV-2 infection.

RESULTS

Compared to the HBV (-) group, the HBV ( +) group had a longer hospital stay (15 (9-22) days vs. 9 (5-16) days). Longitudinal comparisons of laboratory indicators from T1 to T3 showed a continuous decline in TP and ALB levels and a continuous increase in PT and TT levels in the HBV ( +) group. BUN levels increased during T2 and decreased thereafter. These differences were considered statistically significant (P < 0.05). Notably, the HBV ( +) group had a higher proportion of indicators elevated > 3 ULN from T1 to T2, including ALT (1.95%/5.19%), AST (3.25%/12.99%), ALP (1.95%/3.25%), GGT (4.55%/9.09%), TBIL (6.49%/9.09%), and DBIL (18.18%/22.73%). In the HBV (-) group, the elevations were mainly concentrated within 1-2 ULN, including AST (12.99%/22.08%), DBIL (10.39%/21.43%), BUN (12.99%/22.08%), CREA (20.13%/29.22%), and PLT (7.79%/14.94%). Furthermore, the incidence of liver injury from T1 to T3 was higher in the HBV ( +) group compared to the HBV (-) group (15.7% (20/127) vs. 7.2% (11/152), P < 0.05). Multivariate analysis showed that liver cirrhosis (HR = 4.847, 95% CI: 1.224-19.20, P = 0.025) and liver cancer (HR = 8.333, 95% CI: 2.156-32.209, P = 0.002) were independent risk factors for liver injury in the presence of SARS-CoV-2 infection.

CONCLUSION

SARS-CoV-2 infection has a higher proportion of liver injury in HBV-infected patients, affecting hepatic protein synthesis function. Those with cirrhosis and hepatocellular carcinoma are at higher risk of severe liver injury.

The Impact of SARS-CoV-2 on Liver Diseases and Potential Phytochemical Treatments

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has brought about numerous challenges. One of these challenges is the impact of SARS-CoV-2 on the liver. Although this virus primarily affects the lungs, it can induce elevated transaminase levels and the development of scar tissue in the liver, exacerbating preexisting liver conditions. Individuals with preexisting conditions, such as nonalcoholic fatty liver disease, alcohol-induced liver disease and hepatocellular carcinoma, face an increased risk of mortality from COVID-19. However, drugs currently used to treat COVID-19 have undesirable side effects, which make them unsuitable for patients with preexisting liver conditions. In this review, we explore the potential of phytochemicals, such as apigenin, berberine, curcumin, epigallocatechin-3-gallate, quercetin, resveratrol and silymarin, for treatment of the liver conditions, including nonalcoholic fatty liver disease, alcohol-induced liver disease and hepatocellular carcinoma. We also discuss significant associations between phytochemicals and COVID-19 by depicting their molecular interactions. Based on the discussed overlapping functions, it is important to assess the therapeutic efficacy of phytochemicals that possess hepatoprotective properties as potential alternative treatments for COVID-19.

COVID-19: a multi-organ perspective

In this mini review, we explore the complex network of inflammatory reactions incited by SARS-CoV-2 infection, which extends its reach well beyond the respiratory domain to influence various organ systems. Synthesizing existing literature, it elucidates how the hyperinflammation observed in COVID-19 patients affects multiple organ systems leading to physiological impairments that can persist over long after the resolution of infection. By exploring the systemic manifestations of this inflammatory cascade, from acute respiratory distress syndrome (ARDS) to renal impairment and neurological sequelae, the review highlights the profound interplay between inflammation and organ dysfunction. By synthesizing recent research and clinical observations, this mini review aims to provide an overview of the systemic interactions and complications associated with COVID-19, underscoring the need for an integrated approach to treatment and management. Understanding these systemic effects is crucial for improving patient outcomes and preparing for future public health challenges.

Prognostic Utility of dNLR, ALRI, APRI, and SII in COVID-19 Patients with Diabetes: A Cross-Sectional Study

The coronavirus disease 2019 (COVID-19) pandemic has necessitated the identification of biomarkers that can predict disease severity, particularly in vulnerable populations such as individuals with diabetes. This study aims to evaluate the predictive value of inflammatory and liver function markers, specifically derived Neutrophil to Lymphocyte Ratio (dNLR), aspartate aminotransferase (AST)-to-lymphocyte ratio (ALRI), AST to Platelet Ratio Index (APRI), and Systemic Inflammation Index (SII), in COVID-19 patients with and without diabetes. This cross-sectional study included 336 participants, comprising 168 patients with diabetes matched with 168 without, based on gender, body mass index (BMI), and COVID-19 severity at hospitalization. The study was conducted at Victor Babes Hospital for Infectious Diseases and Pulmonology from January 2021 to December 2023. All participants had a confirmed SARS-CoV-2 infection and met the inclusion criteria of being 18 years or older with type 1 or type 2 diabetes as per American Diabetes Association guidelines. At 3 days post symptom onset, significant differences in inflammatory and liver function markers were observed between the two groups. The dNLR, ALRI, APRI, and SII were notably higher in diabetic patients. At a dNLR cutoff of 2.685, the sensitivity and specificity were 70.312% and 65.978%, respectively, with an AUC of 0.624 (p < 0.001). The ALRI showed a cutoff of 0.812, with a sensitivity of 76.429% and specificity of 69.541% (AUC 0.752, p < 0.001). These markers demonstrated statistically significant hazard ratios at both 3 and 7 days, indicating their predictive relevance for severe COVID-19 outcomes. For instance, at 7 days, SII demonstrated a hazard ratio of 2.62 (CI: 1.29-5.04, p < 0.001), highlighting its strong prognostic capability. The study successfully identified significant differences in inflammatory and liver function markers between COVID-19 patients with and without diabetes, with these markers showing good predictive value for disease severity. The results underscore the potential of these biomarkers, particularly ALRI and SII, as valuable tools in managing COVID-19, aiding in the timely identification of patients at increased risk of severe outcomes.

Drug-induced liver injury as assessed by the updated Roussel Uclaf Causality Assessment Method following mild COVID-19 in a patient under anastrozole therapy-A case report

BACKGROUND

Anastrozole is a selective aromatase inhibitor used for the treatment of postmenopausal hormone-sensitive breast cancer. The major side effects include osteoporosis, hypercholesterolemia, and musculoskeletal events, such as arthralgia and myalgia. Other adverse events are rare, including symptoms of acne, masculinization, and drug-induced liver injury, with the latter reported in a few cases only.

CASE

Here, we report on a patient under anastrozole therapy who developed drug-induced liver injury as assessed by the updated Roussel Uclaf Causality Assessment Method 5 weeks after a mild SARS-CoV-2 infection, which is, to the best of our knowledge, the first report of its kind involving anastrozole. Discontinuation of anastrozole resulted in a marked improvement of the alanine aminotransaminase, and aspartate aminotransaminase as well as normalized lactate dehydrogenase serum levels already seen after 26 days. Surprisingly, however, the cholestatic serum markers gamma-glutamyl transpeptidase and alkaline phosphatase showed a further rise, and took another 4 weeks to drop significantly.

CONCLUSION

The presentation of this case is meant to alert physicians to a potential drug-induced liver injury following mild SARS-CoV-2 infection in patients under anastrozole medication.
