Safety and efficacy of additional levofloxacin in tuberculous meningitis: A randomized controlled pilot study
Abstract
BACKGROUND: Levofloxacin is an effective bactericidal category III antitubercular drug. There is paucity of studies comparing the role of additional levofloxacin to standard antitubercular regimen in the patients with tuberculous meningitis (TBM).
AIMS: To compare the safety and efficacy of adding levofloxacin to standard four drug ATT regimen (RHZE).
SUBJECTS AND METHODS: The patients with TBM diagnosed on the basis of clinical, cerebrospinal fluid (CSF) and MRI criteria were included. Children below 15 years, patients with pregnancy, seizures, liver failure, kidney failure and malignancy were excluded. The baseline clinical, CSF and MRI characteristics were noted and consciousness was evaluated by Glasgow Coma Scale (GCS). The patients were randomized to RHZE (rifampicin, isoniazid, pyrazinamide and ethambutol) and RHZEL (RHZE and levofloxacin) groups. Outcome was defined at 6 months. Primary outcome was death and secondary outcomes were disability as assess by Barthel Index score and adverse events.
RESULTS: Out of 110 TBM patients screened, 57 fulfilled the inclusion criteria. Their median age was 35 (15-75) years. 29 patients received RHZEL and 28 RHZE. The baseline clinical, biochemical and MRI characteristics were similar in the two groups. At 6 months, 11 (19.3%) patients died, 38 (66.7%) had good and 7 (12.3%) poor outcome. There was insignificant survival benefit in RHZEL group compared to RHZE (HR-2.61, 95% CI 0.73-9.36, P = 0.14), 25% patients died in RHZE where…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 110 participants or records.
