Insights

Patients with COVID-19 and liver injury (LI) face significantly higher risks of mortality and poor outcomes. This large study highlights the severe consequences of liver injury in coronavirus disease 2019 patients.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Critical Care Medicine

Background:

  • Liver injury (LI) is common in COVID-19 patients.
  • Large-scale studies on risk factors and outcomes of LI in COVID-19 are limited.

Purpose of the Study:

  • To evaluate risk factors and clinical outcomes of LI in a large inpatient COVID-19 cohort.
  • To compare outcomes of patients with mild liver enzyme elevation (MEL) and LI against a control group.

Main Methods:

  • Included adult COVID-19 patients hospitalized between March and April 2020.
  • Defined LI and MEL based on peak liver enzyme levels (ALT/AST, ALP/bilirubin).
  • Compared patients with MEL and LI to a control group with normal liver enzymes.

Main Results:

  • 53.2% had MEL, 20.5% had LI among 1935 patients.
  • LI group had higher proportion of men, older patients, and African-Americans.
  • LI significantly increased risk of mortality (RR 4.26), ICU admission (RR 5.52), intubation (RR 11.01), and 30-day readmission (RR 1.81).

Conclusions:

  • COVID-19 patients with liver injury face significantly increased mortality risk.
  • Liver injury is associated with poorer clinical outcomes in coronavirus disease 2019.
  • Findings underscore the importance of monitoring liver function in COVID-19 patients.

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Inflammatory Bowel Disease I: Ulcerative Colitis

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...
