Abstract

Insights

Spontaneous fungal peritonitis (SFP) in cirrhosis patients leads to higher mortality, longer hospital stays, and increased costs compared to bacterial infections. Early diagnosis and antifungal treatment are crucial for better outcomes.

Area of Science:

  • Infectious Diseases
  • Hepatology
  • Critical Care Medicine

Background:

  • Cirrhosis impairs immune function, increasing susceptibility to infections.
  • Fungal infections in cirrhosis patients often present with delayed diagnosis and high mortality.
  • Prompt diagnosis and treatment of fungal infections are critical for this vulnerable population.

Purpose of the Study:

  • To analyze outcomes of cirrhotic patients readmitted with bacterial and fungal infections.
  • To compare in-hospital mortality, length of stay, and hospital resource utilization between spontaneous bacterial peritonitis (SBP) and spontaneous fungal peritonitis (SFP).

Main Methods:

  • Retrospective cohort study using the Nationwide Readmission Database (NRD) from 2016-2020.
  • Analysis of 393,195 index hospitalizations, focusing on 30-day and 90-day readmissions for SBP and SFP.
  • Hospital costs calculated using HCUP Cost-to-Charge Ratio files, adjusted for inflation.

Main Results:

  • SFP was associated with significantly increased mortality, longer length of stay (LOS), and higher hospital charges compared to SBP (P < 0.001).
  • Mean LOS for SFP ranged from 14.9 to 32.3 days, with Aspergilloses having the longest duration.
  • 30-day index admission charges were $51,739 for SFP versus $42,258 for SBP; readmission charges were $89,913 for SFP versus $64,266 for SBP.

Conclusions:

  • Spontaneous fungal peritonitis (SFP) presents worse outcomes than spontaneous bacterial peritonitis (SBP) in cirrhotic patients.
  • SFP should be considered in patients with cirrhosis who do not respond to antibiotic therapy.
  • Early recognition and antifungal treatment are vital for improving patient outcomes in SFP.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

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...

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...

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...

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...
