Tuberculous meningitis in children

Abstract

Initial empiric treatment for central nervous system (CNS) tuberculosis should include four antituberculous drugs until results of cultures and sensitivities are available. Treatment should include isoniazid, rifampin, pyrazinamide, and either ethambutol or streptomycin. Total treatment should extend for 12 months. Daily therapy should be used for the first 2 months, followed by either twice a week treatment or continued with daily therapy for the duration with directly observed therapy (DOT). Pyrazinamide should be included in all treatment regimes for the first 2 months of therapy. Corticosteroids should be used in the management of children with tuberculous meningitis. Corticosteroids have been shown to decrease mortality, long-term neurologic complications, and permanent sequelae. Prednisone is often used at a dosage of 1 to 2 mg/kg per day. Steroids should be used for 4 to 6 weeks, and then tapered over the next 2 to 3 weeks. Cerebrospinal fluid (CSF) cultures and other infected sites must be aggressively pursued in order to obtain an organism for identification and sensitivities testing. Cranial CT scans with contrast should be included in the early diagnostic work-up of a child with suspected CNS tuberculosis infection. Hydrocephalus is often an early finding and may be helpful in establishing the diagnosis of CNS tuberculosis. Treatment of CNS tuberculosis should be for 12 months. All children with CNS tuberculosis should be promptly reported to the local public health department. Public health will facilitate the case-contact study and assist with follow-up and DOT after discharge. Directly observed therapy should be given for the entire treatment course. This is best accomplished with the collaboration of local public health services. Children with tuberculous meningitis should be evaluated in follow-up monthly. Monitoring should include determining adherence to drug treatment, an interval history for signs and symptoms of disease progression, careful physical examinations and evaluation for adverse effects of drugs. Liver function tests should be obtained at baseline, 2-, 4-, 6-, and 8 weeks, and then monthly for the first several months of treatment. Children with tuberculous meningitis should be tested for HIV infection, including pre- and post-test counseling.

Traitement de la tuberculose

“…L'adjonction d'un stéroïde est indiquée dans les cas graves de tuberculose cérébrale ou ménin-gée accompagnés de signes d'hypertension intracrânienne au début du traitement [42] ainsi que dans les tuberculoses bronchiques sténosantes, notamment chez l'enfant, et dans la péricardite. Elle n'a pas fait ses preuves en cas de pleurésie tuberculeuse [43].…”
