Insights

Patients with Cushing's syndrome (CS) have a significant prevalence of hepatitis B virus (HBV) infection. Antiviral prophylaxis should be considered for these patients due to the risk of HBV reactivation.

Area of Science:

  • Endocrinology
  • Hepatology
  • Immunology

Background:

  • Hepatitis B virus (HBV) reactivation is a risk in immunosuppressed individuals.
  • Current guidelines address exogenous corticosteroids but not endogenous hypercortisolemia in Cushing's syndrome (CS).

Purpose of the Study:

  • To determine the prevalence of HBV infection in CS patients.
  • To evaluate the need for antiviral prophylaxis in CS patients.

Main Methods:

  • Retrospective analysis of 72 CS patients screened for HBV (2016-2021).
  • Patients categorized by cortisol burden: overt CS, mild autonomous cortisol secretion (MACS), and remission.
  • Analysis of HBV serology and clinical outcomes over time.

Main Results:

  • 19.4% of CS patients were anti-HBc IgG positive; 4 had chronic HBV, 15 had isolated anti-HBc IgG.
  • 5.5% of patients were HBsAg positive, indicating inactive chronic HBV.
  • Two patients experienced HBV reactivation, and one had an HBV flare.

Conclusions:

  • CS patients exhibit a notable prevalence of HBV infection.
  • Long-term hypercortisolemia in CS necessitates a consensus on HBV screening, follow-up, and prophylaxis.
  • Prophylaxis is particularly important in regions with high HBV prevalence.

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Hepatic Drug Excretion: Enterohepatic Cycling01:17

Hepatic Drug Excretion: Enterohepatic Cycling

Enterohepatic cycling involves the active secretion of drugs and their metabolites into the bile via transporters in the canalicular membrane of hepatocytes. This secretion is an integral part of the digestive process, releasing these substances into the gastrointestinal (GI) tract.
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Adrenal Gland Disorders

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

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...
