Insights

Angiotensin-converting enzyme inhibitors (ACEIs) significantly reduced hepatocellular carcinoma (HCC) risk in patients with chronic hepatitis B (HBV) and hypertension. Higher ACEI doses and longer treatment duration correlated with greater risk reduction.

Area of Science:

  • Hepatology
  • Cardiovascular Pharmacology
  • Oncology

Background:

  • Chronic hepatitis B virus (HBV) infection is a primary driver of hepatocellular carcinoma (HCC).
  • Angiotensin-converting enzyme inhibitors (ACEIs) show potential in mitigating HCC risk by influencing hepatic fibrogenesis, but large-scale data are scarce.

Purpose of the Study:

  • To investigate the association between ACEI use and HCC incidence in a nationwide cohort of patients with chronic HBV and hypertension.
  • To evaluate the dose-response relationship and impact of treatment persistence on HCC risk reduction.

Main Methods:

  • A nationwide cohort study utilized Taiwan's National Health Insurance Research Database (2010-2020).
  • Propensity score matching and time-varying Cox models were employed to analyze incident HCC risk in adult chronic HBV patients with hypertension, defining ACEI use by cumulative defined daily doses (cDDDs).

Main Results:

  • After propensity score matching (n=118,715 per group), ACEI users exhibited significantly lower HCC risk (aHR, 0.66).
  • A pronounced dose-dependent effect was observed, with the highest ACEI cDDD quartile showing the greatest risk reduction (aHR, 0.29).
  • The protective association remained consistent irrespective of concurrent nucleos(t)ide analogue therapy and was stronger with treatment persistence (>1 year).

Conclusions:

  • ACEI use is linked to a substantial, dose-dependent decrease in HCC risk among hypertensive patients with chronic HBV.
  • Repurposing ACEIs offers a promising strategy for HCC chemoprevention, especially for HBV carriers with hypertension ineligible for antiviral treatments.

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

Antihypertensive Drugs: Direct Renin Inhibitors

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

Antihypertensive Drugs: Angiotensin II Receptor Blockers

In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

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 binding...

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

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...
