Restrictive antibiotherapy after renal transplantation.

Area of Science:

• Nephrology
• Infectious Diseases
• Transplantation Medicine

Background:

• Renal transplantation outcomes are significantly impacted by post-operative infections.
• Prophylactic antibiotic use is common but may contribute to resistance and side effects.

Purpose of the Study:

• To evaluate the benefits of a protocol involving surveillance and targeted infection treatment in renal transplant recipients.
• To assess the impact of a restrictive antibiotic policy on infection management and patient outcomes.

Main Methods:

• Follow-up of 42 patients after 44 renal transplantations.
• Systematic microbiologic and clinical surveillance for infections.
• Aggressive etiologic investigation and cause-specific antibiotic selection.
• Avoidance of prophylactic antibiotherapy.

Main Results:

• 124 infections recorded over 18,030 follow-up days (110 bacterial, 11 viral, 3 protozoal).
• Common infection sites: urinary tract (80), skin wounds (17), lower respiratory tract (10).
• Low incidence of septicemia (3) and infection-related mortality (1).
• Restrictive antibiotic use: Ampicillin and "minor" drugs used 74.5% of the time; gentamicin 2.6%; combined therapy 1.2%.

Conclusions:

• A restrictive policy for antibiotic therapy in renal transplant recipients is associated with favorable outcomes.
• Systematic surveillance and targeted treatment effectively manage infections while minimizing antibiotic exposure.
