[TREATMENT AND PREVENTION OF BACTERIAL AND MYCOTICINFECTION IN ACUTE LIVER FAILURE]
Abstract:
Patients with acute liver failure (ALF) have increased susceptibility to nosocomial and opportunistic infections as a result of various immune defects and the need for invasive monitoring procedures. Bacteriologically proven infection was recorded in up to 80% of these patients and, fungal infection in 32%. Clinical signs such as high temperature and high WBC are absent in 30% of the cases. These patients are prone to develop multiple and concomitant infections. The most common infection in ALF patients is pneumonia, accounting for 50% of episodes. These infections occurs early in the course of the disease. Selective parenteral and enteral antisepsis regimens (SPEAR) were evaluated in prospective controlled studies. Although in a initial study there was an overall reduction of infection episodes. A recent study has shown that the administration of oral non-absorbable antibacterials did not confer any additional benefit over prophylactic systemic antibacterials. In conclusion it is clear that antimicrobial prophylaxis does dramatically reduce the risk of infectious complications and contribute to the improvement in mortality from ALF.
Insights
Antimicrobial prophylaxis significantly reduces infectious complications in acute liver failure (ALF) patients, improving survival rates. Early intervention is crucial as infections like pneumonia are common and often lack typical symptoms.
Area of Science:
- Infectious Diseases
- Hepatology
- Critical Care Medicine
Background:
- Patients with acute liver failure (ALF) exhibit profound immune dysfunction, increasing susceptibility to nosocomial and opportunistic infections.
- Infections, particularly pneumonia, are frequent early complications in ALF, often presenting without classic signs like fever or elevated white blood cell (WBC) counts.
- Up to 80% of ALF patients experience bacteriologically proven infections, with fungal infections occurring in 32%.
Purpose of the Study:
- To evaluate the efficacy of selective parenteral and enteral antisepsis regimens (SPEAR) in reducing infection episodes in ALF patients.
- To assess the impact of antimicrobial prophylaxis on infectious complications and mortality in acute liver failure.
Main Methods:
- Review of prospective controlled studies evaluating antimicrobial prophylaxis strategies, including SPEAR.
- Analysis of infection rates, types of infections (bacterial and fungal), and clinical presentation in ALF patients.
- Comparison of outcomes between prophylactic systemic antibacterials and oral non-absorbable antibacterials.
Main Results:
- Initial studies indicated an overall reduction in infection episodes with SPEAR.
- Recent findings suggest that oral non-absorbable antibacterials offer no additional benefit over prophylactic systemic antibacterials.
- Pneumonia is the most common infection, occurring in 50% of episodes, often early in the disease course.
Conclusions:
- Antimicrobial prophylaxis is essential for reducing infectious complications in acute liver failure.
- Prophylactic strategies significantly contribute to improving mortality rates in ALF patients.
- The absence of typical infection signs (fever, high WBC) in 30% of ALF patients underscores the need for vigilant monitoring and prophylaxis.
