Insights

Abnormal liver enzymes in COVID-19 patients without chronic liver disease indicate a higher risk of in-hospital death and need for mechanical ventilation. Cholestasis poses the greatest danger.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Critical Care Medicine

Background:

  • Coronavirus disease 2019 (COVID-19) infection frequently causes abnormal liver enzymes.
  • The long-term impact of these hepatic enzyme elevations remains unclear.

Purpose of the Study:

  • To determine the prevalence and prognostic significance of initial liver enzyme levels in a large cohort of COVID-19 patients.
  • To assess the association between liver enzyme abnormalities and clinical outcomes in COVID-19 survivors and non-survivors.

Main Methods:

  • Retrospective analysis of electronic medical records for 10,614 COVID-19 patients admitted between March 1, 2020, and April 30, 2020.
  • Analysis of baseline demographics and liver chemistries.
  • Primary outcome: in-hospital mortality. Secondary outcome: composite of in-hospital mortality or mechanical ventilation.

Main Results:

  • Patients with abnormal liver tests exhibited increased risks of mortality and the composite outcome compared to those with normal liver enzymes.
  • These associations persisted after adjusting for demographic factors.

Conclusions:

  • Liver enzyme abnormalities are linked to increased mortality and mechanical ventilation needs in COVID-19 patients without pre-existing liver disease.
  • Cholestasis in COVID-19 patients is associated with the highest risk of adverse outcomes.

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...

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...

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...
