Infectious arthritis in renal transplant patients

Area of Science:

• Nephrology
• Rheumatology
• Infectious Diseases

Background:

• Infectious complications are common in renal transplant patients.
• Septic arthritis is an infrequent but serious complication.
• Literature review revealed only 16 reported cases of infectious arthritis in transplant patients.

Purpose of the Study:

• To document the incidence and characteristics of septic arthritis in renal transplant recipients.
• To identify predisposing factors and clinical features of septic arthritis in this population.
• To emphasize the importance of monitoring the locomotor system in transplant patients.

Main Methods:

• Retrospective case review of renal transplant recipients over an 18-year period.
• Analysis of clinical data, synovial fluid analysis, and blood cultures.
• Literature search for reported cases of infectious arthritis in transplant patients.

Main Results:

• Six cases of septic arthritis were identified among over 800 renal transplants.
• The knee was the most commonly affected joint.
• Predisposing factors were present in all cases, with 3 having prior infections with the same organism. Initial joint infection occurred within 18 months post-transplant. Synovial fluid white blood cell counts were typically elevated, but peripheral blood counts were not always indicative. Blood cultures were positive in most bacterial cases.

Conclusions:

• Septic arthritis is a rare but significant complication in renal transplant recipients.
• Early recognition and management are essential, considering potential mimics.
• Vigilance regarding the musculoskeletal system is warranted in post-transplant care.
