Abstract:
Antimicrobial resistance has become a major global public health security problem that needs coordinated approaches at regional, national and international levels. Antibiotic overuse and the failure of control measures to prevent the spread of resistant bacteria in the healthcare environment have led to an alarming increase in the number of infections caused by resistant bacteria, organisms that resist many (multi-drug and extensively drug-resistant strains), if not all (pan-drug-resistant bacteria) currently available antibiotics. While Gram-positive cocci resistance (methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci) shows a heterogeneous geographical distribution, extended-spectrum β-lactamase-producing Enterobacteriaceae and carbapenem-resistant Enterobacteriaceae have become pandemic worldwide and endemic in some parts of the world, respectively. Moreover, currently available therapeutic options for resistant bacteria are very limited, with very few new agents in development. Antimicrobial resistance is especially relevant in decompensated cirrhosis. Firstly, cirrhotic patients are highly susceptible to develop infections caused by resistant bacteria as risk factors of multiresistance concentrate in this population (mainly repeated hospitalizations and antibiotic exposure). Secondly, inappropriate empirical antibiotic schedules easily translate into increased morbidity (acute kidney injury, acute-on-chronic liver failure, septic shock) and hospital mortality in advanced cirrhosis. Therefore, hepatologists must face nowadays a complex clinical scenario that requires new empirical antibiotic strategies that may further spread resistance. Global, regional and local preventive measures should therefore be implemented to combat antimicrobial resistance in cirrhosis including the restriction of antibiotic prophylaxis to high-risk populations, investigation on non-antibiotic prophylaxis, stewardship programs on adequate antibiotic prescription and on increasing awareness of the problem among health professionals, and well-defined early de-escalation policies based on rapid microbiological diagnostic tests. Other infection control practices such as hand hygiene and barrier precautions are also important. Clinical impact and cost-effectiveness of epidemiological surveillance programs (periodic rectal and nasal swabs) should also be explored.
Insights
Antimicrobial resistance is a global health crisis, particularly impacting patients with decompensated cirrhosis due to increased susceptibility and limited treatment options. New strategies are crucial to combat resistant infections in this vulnerable population.
Area of Science:
- Public Health
- Infectious Diseases
- Hepatology
Background:
- Antimicrobial resistance (AMR) is a significant global health threat, driven by antibiotic overuse and inadequate infection control.
- Resistant bacterial infections, including multi-drug and pan-drug resistant strains, are increasing worldwide.
- Decompensated cirrhosis patients face heightened susceptibility to resistant infections due to factors like frequent hospitalizations and antibiotic exposure.
Purpose of the Study:
- To highlight the critical challenge of antimicrobial resistance in decompensated cirrhosis.
- To discuss the increased morbidity and mortality associated with resistant infections in cirrhotic patients.
- To propose strategies for combating AMR in this population.
Main Methods:
- Review of current literature on antimicrobial resistance in cirrhosis.
- Analysis of risk factors and clinical outcomes in cirrhotic patients with resistant infections.
- Discussion of preventive measures and therapeutic strategies.
Main Results:
- Cirrhotic patients exhibit a high risk for infections caused by resistant bacteria.
- Inappropriate antibiotic regimens in cirrhosis lead to severe complications like acute kidney injury, liver failure, and septic shock.
- Limited therapeutic options are available for treating resistant bacterial infections.
Conclusions:
- Hepatologists must adopt new empirical antibiotic strategies to manage resistant infections in cirrhosis.
- Implementing global, regional, and local preventive measures is essential, including restricted antibiotic prophylaxis, non-antibiotic prophylaxis research, stewardship programs, and rapid diagnostics for de-escalation.
- Enhanced infection control practices and surveillance programs are vital for combating AMR in cirrhosis.
