Infections in organ transplant patients
Bacterial infections represent the major cause of morbidity in patients undergoing solid organ transplantation (SOT). Soft tissue infections from bacteria generally occur in the first month after transplantation when the skin is disrupted by the surgery itself or by indwelling catheters and lines. Incidence of wound infections in solid organ transplant patients ranges from 2% to 56%, depending on surgical technique, host characteristics, and antibiotic prophylaxis. The skin flora is also the culprit when introduced to less tolerant tissue such as the transplanted organ itself. This can lead to pyelonephritis and cystitis in renal transplant recipients, cholangitis, and intra-abdominal abscesses in liver transplants, and bronchitis and pneumonia in the lung transplant recipient. Frequently, bacteremia ensues and may again come to the attention of a dermatologist as a subcutaneous abscess from hematogenous spread.
