Abstract

Insights

Severe alcoholic hepatitis (AH) patients treated with corticosteroids face a high risk of invasive fungal infections, particularly invasive aspergillosis (IA), leading to a near 100% mortality rate.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Critical Care Medicine

Background:

  • Severe alcoholic hepatitis (AH) carries a high short-term mortality risk, often due to infections.
  • The incidence and impact of invasive fungal infections in AH patients receiving corticosteroids remain largely unknown.

Purpose of the Study:

  • To investigate the incidence of invasive mycosis in patients with severe alcoholic hepatitis treated with corticosteroids.
  • To determine the impact of invasive fungal infections on mortality in this patient population.

Main Methods:

  • Retrospective analysis of 12 intensive care unit (ICU) patients with histologically proven AH.
  • Patients were treated with corticosteroids, with some also receiving pentoxifylline.

Main Results:

  • Five patients developed invasive aspergillosis (IA), three had candidemia, and two had Candida colonization.
  • IA was associated with 100% mortality, while candidemia had a 70% mortality rate.
  • Only two patients showed no evidence of fungal infection.

Conclusions:

  • Patients with severe AH exhibit increased susceptibility to invasive mycosis.
  • Invasive fungal infections in AH patients are associated with high mortality, necessitating high clinical suspicion and prophylactic strategies.

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to...

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.

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...

Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
