Insights

Direct-acting antivirals (DAAs) improve liver stiffness in chronic hepatitis C (CHC) patients. However, high baseline glucose levels impede fibrosis regression and may increase hepatocellular carcinoma (HCC) risk, highlighting the importance of glycemic control.

Area of Science:

  • Hepatology
  • Viral Hepatitis
  • Metabolic Syndrome

Background:

  • Chronic hepatitis C (CHC) remains a significant global health issue.
  • Direct-acting antivirals (DAAs) achieve high sustained virologic response (SVR) rates.
  • Factors influencing fibrosis regression and hepatocellular carcinoma (HCC) development post-SVR require further investigation.

Purpose of the Study:

  • To evaluate hepatic stiffness regression at 24 weeks post-SVR (SVR24).
  • To identify factors impacting hepatic stiffness changes after DAA treatment.
  • To explore the relationship between glycemic status and outcomes in CHC patients post-DAA therapy.

Main Methods:

  • Retrospective analysis of 166 CHC patients treated with DAAs.
  • Assessment of hepatic stiffness using acoustic radiation force impulse (ARFI).
  • Collection of anthropometric and biochemical parameters at baseline and SVR24.

Main Results:

  • Viral eradication significantly improved hepatic stiffness, liver enzymes (ALT, AST, γGT), and platelet count.
  • Patients with baseline glucose > 110 mg/dL showed significantly less hepatic stiffness regression.
  • Baseline HbA1c strongly correlated with the change in hepatic stiffness (DeltaStiffness).
  • Hyperglycemic patients who developed HCC (4.2%) exhibited no stiffness regression or platelet count recovery.

Conclusions:

  • DAA treatment offers overall benefits for CHC patients, including improved liver stiffness.
  • Glycemic decompensation negatively impacts liver fibrosis regression.
  • Hyperglycemia may facilitate HCC development in CHC patients post-DAA therapy.

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...

Hepatic Drug Clearance: Restrictive and Nonrestrictive Clearance01:09

Hepatic Drug Clearance: Restrictive and Nonrestrictive Clearance

Hepatic clearance refers to the volume of blood cleared of a drug by the liver per unit of time. It plays a crucial role in drug metabolism and elimination. While hepatic clearance is commonly estimated by subtracting renal clearance from total body clearance, other pathways, such as pulmonary or biliary clearance, may also contribute. However, these pathways are generally less significant than hepatic and renal clearance.
Most drugs undergo restrictive clearance, which is proportional to the...

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: 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...

Hepatic Drug Clearance: Effect of Protein Binding01:09

Hepatic Drug Clearance: Effect of Protein Binding

Hepatic clearance is influenced by protein binding based on the drug's extraction ratio. Drugs with high extraction ratios are considered flow-limited and remain unaffected by protein binding during hepatic clearance. On the other hand, drugs with low extraction ratios may be impacted by plasma protein binding, although the extent of this influence depends on the fraction of the drug bound.
For low-extraction-ratio drugs that are less than 80% protein-bound, minor changes in protein binding...

Hepatic Drug Excretion: Influencing Factors01:16

Hepatic Drug Excretion: Influencing Factors

The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...
