Successful treatment of tuberculous meningitis in an Indian female under hemodialysis therapy

Hemodialysis is a well-known risk factor for severe infection by putting patients under an immunocompromised state. Such patients are prone to opportunistic pathogen and present with atypical manifestations during infection. Tuberculous meningitis is a central nervous system infection of Mycobacterium tuberculosis, accounting for the highest mortality of all forms of tuberculosis. In fact, the mortality rate of tuberculous meningitis in hemodialysis patients is extremely poor because early clinical diagnosis is difficult. Here, we report a case of tuberculous meningitis in a 61-year-old Indian hemodialysis patient, who presented with fever of unknown origin and was successfully treated with empiric treatment with standard four-drug regimen against tuberculosis. Comprehensive screening of the origin of fever revealed only the positive results of interferon-gamma release assay, which led us to initiate an empiric therapy for tuberculosis, before making a definitive diagnosis by cerebrospinal fluid nested PCR. Soon after the initiation of the treatment, the fever immediately abated. Although the patient experienced a single episode of paradoxical worsening and severe liver injury, she recovered well without any complications. This report provides a clinical course of the disease in a hemodialysis patient, highlighting the importance of early clinical diagnosis and rapid initiation of empirical tuberculosis treatment.
