[Persistent neutrophilic meningitis in a patient with the acquired immunodeficiency syndrome].
Persistent neutrophilic meningitis is rarely found and it is characterized by predominance of the number of neutrophils in samples of C SF (cerebrospinal fluid) from the patient after seven days of treatment. The above patient in HIV positive; he has developed fever and mental disorder for 4 months and has presented neutrophilic pleocytosis in analysis of CSF for more than 5 months. Since the beginning or the treatment he has taken antituberculous drugs and corticosteroids. For 3 months, the serologic evaluation, smears and cultures were negative. On the 60th day in hospital, the investigation of acid-fast bacilli in CSF was positive and culture confirmed the presence of Mycobacterium tuberculosis resistant to isoniazid. Several factors that may have caused this uncommon development were discussed: the disturbance of cell-mediated immunity, mainly in release of IL 8 and TNF, the simultaneous use of medicines that could alter the CSF concentration of antituberculous drugs, and the increasing number of multiresistant strains.
