Bacterial meningitis in solid organ transplant recipients: a population-based prospective study

Area of Science:

• Infectious Diseases
• Nephrology
• Immunology

Background:

• Solid organ transplant (SOT) recipients are susceptible to central nervous system infections.
• The incidence and clinical characteristics of bacterial meningitis in SOT recipients remain poorly understood.

Purpose of the Study:

• To investigate the occurrence, clinical course, and prognosis of bacterial meningitis in SOT recipients in the Netherlands.
• To compare the incidence of bacterial meningitis in renal transplant recipients to the general population.

Main Methods:

• A nationwide prospective cohort study on community-acquired bacterial meningitis (2006-2014) was utilized.
• Data from SOT recipients (>16 years old) with bacterial meningitis were analyzed, including prospective and retrospective information.
• Incidence rates were calculated and compared to the general population.

Main Results:

• Six SOT recipients, all renal transplant recipients, were identified.
• The annual incidence of bacterial meningitis was sevenfold higher in renal transplant recipients compared to the general population.
• Atypical presentations were common (83%), seizures occurred in 33%, and 67% had an unfavorable functional outcome.

Conclusions:

• Bacterial meningitis is a rare but severe complication in SOT recipients.
• SOT recipients have a high risk of meningitis, often presenting atypically, making diagnosis challenging.
• Prompt recognition and management are vital for improving outcomes in this vulnerable population.
