Insights

Antiphospholipid antibodies (aPLs) were found in 12.6% of hepatitis B virus (HBV)-infected patients, primarily as IgM anticardiolipin antibodies (aCL Ab). Most aPLs persisted for 12 weeks, showing a weak association with Antiphospholipid Syndrome (APS) clinical manifestations.

Area of Science:

  • Immunology
  • Hepatology
  • Infectious Diseases

Background:

  • Infections are frequently linked to antiphospholipid antibodies (aPLs).
  • Hepatitis B virus (HBV) infection is a common global health concern.

Purpose of the Study:

  • To determine the prevalence, persistence, clinical significance, and characteristics of aPLs in HBV-infected patients.
  • To investigate the association between aPLs and clinical manifestations in HBV infection.

Main Methods:

  • Assessed anticardiolipin antibodies (aCL Ab), anti-β(2)-glycoprotein I antibodies (β(2)GPI Ab), and lupus anticoagulant (LA) in 143 HBV patients and 32 controls.
  • Follow-up specimens were collected from patients with elevated aPL levels.

Main Results:

  • A total of 12.6% of HBV patients tested positive for aPLs, predominantly IgM aCL Ab.
  • Persistent aPLs were observed in 71.4% of patients over a 12-week period.
  • No significant clinical manifestations related to aPLs were identified in the study cohort.

Conclusions:

  • IgM aCL Ab were the most common aPLs in HBV infection, with a weak link to Antiphospholipid Syndrome (APS) clinical features.
  • Unlike transient aPLs in other infections, aPLs in HBV patients demonstrated persistent detection over 12 weeks.
  • The findings highlight the distinct profile of aPLs in HBV infection, emphasizing their persistence rather than transient presence.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

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 the...

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Chronic Pancreatitis I: Introduction01:25

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
