Insights

Patients with vascular liver diseases (VLDs), specifically portosinusoidal vascular disease (PSVD) and splanchnic vein thrombosis (SVT), face a higher risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and related mortality. This highlights the need for targeted monitoring and care for these patients during the coronavirus disease 2019 (COVID-19) pandemic.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Epidemiology

Background:

  • Vascular liver diseases (VLDs), including portosinusoidal vascular disease (PSVD), splanchnic vein thrombosis (SVT), and Budd-Chiari syndrome (BCS), are complex conditions.
  • The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on patients with VLDs remains unclear.
  • Assessing COVID-19's effect on VLD patients' hepatic decompensation and survival is crucial.

Purpose of the Study:

  • To evaluate the prevalence and severity of SARS-CoV-2 infection in patients with VLDs.
  • To compare infection rates and outcomes in VLD patients versus the general population (GP).
  • To determine the association between VLDs, COVID-19 severity, hepatic decompensation, and mortality.

Main Methods:

  • An international observational study was conducted from March 2020 to March 2021.
  • Data were collected from 968 patients across Spain and France, including those with PSVD, SVT, and BCS.
  • Infection rates and severity metrics were compared between VLD patients and the GP.

Main Results:

  • The prevalence of SARS-CoV-2 infection was significantly higher in PSVD (19%) and SVT (14%) patients compared to the GP (6.5%).
  • VLD patients experienced increased hospital admissions (14%), ICU admissions (2%), and mortality (4%) from COVID-19 compared to the GP.
  • A history of ascites and post-COVID-19 hepatic decompensation were linked to increased COVID-19 mortality in VLD patients.

Conclusions:

  • Patients with PSVD and SVT are at an elevated risk for SARS-CoV-2 infection.
  • These patient groups also face a higher risk of developing severe COVID-19 disease.
  • VLDs, particularly PSVD and SVT, represent a significant risk factor for adverse COVID-19 outcomes.

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...

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...

Hepatic Portal System01:21

Hepatic Portal System

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...
