Tuberculous meningitis in a renal transplant recipient

Tuberculous meningitis is a very rare, but serious extrapulmonary complication of mycobacterial infections in immunocompromised patients, such as organ transplant recipients. We describe here a 66-year-old Turkish woman without any history of tuberculosis, who received a renal allograft transplant in 1994. After a pilgrimage to an endemic area for tuberculosis, she presented with fever and headache in August 1998. Clinical examination revealed positive meningism and hyperreflexia. Lymphocytosis was noted in her cerebrospinal fluid (CSF) and Mycobacterium tuberculosis infection was detected by PCR within the CSF. Despite immediate triple antituberculosis therapy, the patient's clinical condition deteriorated rapidly, with the development of septic shock syndrome, and she died three weeks after admission due to cardiovascular and respiratory failure. Mycobacterial infections, including extrapulmonary manifestations, should thus be considered in all renal transplant recipients presenting with unexplained fever. Preventive therapy, i.e. isoniazid prophylaxis, may also be recommended for patients risking exposure in areas endemic for tuberculosis.
