- Efficacy and safety of daily treatments for drug-susceptible pulmonary tuberculosis: a systematic review and network meta-analysisPublication . Imazu, Priscila; Santos, Josiane M.; Beraldi-Magalhães, Francisco; Fernandez-Llimos, Fernando; Tonin, Fernanda; Pontarolo, RobertoObjectives: To evaluate and update the evidence on the comparative efficacy and safety of antimicrobial drugs regimens for treating pulmonary drug-susceptible tuberculosis (DS-TB). Methods: A systematic review was performed with searches in PubMed and Scopus (PROSPERO-CRD42019141463). We included randomised controlled trials comparing the effect of any antimicrobial regimen lasting at least 2 weeks. The outcomes of interest were culture conversion and incidence of adverse events. Bayesian network meta-analyses and surface under the cumulative ranking curve (SUCRA) analyses were performed. Results were reported as odds ratio with 95% credibility intervals. Key findings: Fifteen studies were included in the meta-analysis (n = 7560 patients). No regimen was statistically more effective than the WHO standard approach (rifampicin, isoniazid, ethambutol, and pyrazinamide). The use of rifapentine 450 mg instead of rifampicin in the standard regimen demonstrated to be statistically safer than all other options for serious adverse events (e.g. hepatotoxicity, arthralgia) (OR ranging from 0.0 [Crl 0.00-0.04] to 0.0 [0.00-0.97]; SUCRA probabilities of 10%). Therapies containing rifapentine (Rp1500HEZ, Rp900HEZ) and moxifloxacin (RMEZ, RHMZ) are effective regarding culture conversion, but statistical uncertainty on their safety profile exists. Conclusion: The WHO standard regimen remains an overall effective and safe alternative for DS-TB. For intensive phase treatments, drugs combinations with rifapentine and moxifloxacin seem to reduce treatment duration while maintaining efficacy.
- Systematic review with network meta-analysis on the treatments for latent tuberculosis infection in children and adolescentsPublication . Santos, Josiane M.; Fachi, Mariana M.; Beraldi-Magalhães, Francisco; Böger, Beatriz; Junker, Allan M.; Domingos, Eric L.; Imazu, Priscila; Fernandez-Llimos, Fernando; Tonin, Fernanda; Pontarolo, RobertoBackground: We aimed to synthesize the evidence on the efficacy and safety of different treatment regimens for latent tuberculosis infection (LTBI) in children and adolescents. Methods: A systematic review with network meta-analysis was performed (CRD142933). Searches were conducted in Pubmed and Scopus (Nov-2021). Randomized controlled trials comparing treatments for LTBI (patients up to 15 years), and reporting data on the incidence of the disease, death, or adverse events were included. Networks using the Bayesian framework were built for each outcome of interest. Results were reported as odds ratio (OR) with 95% credibility intervals (CrI). Rank probabilities were calculated via the surface under the cumulative ranking analysis (SUCRA) (Addis-v.1.16.8). GRADE approach was used to rate evidence's certainty. Results: Seven trials (n = 8696 patients) were included. Placebo was significantly associated with a higher incidence of tuberculosis compared to all active therapies. Combinations of isoniazid (15–25 mg/kg/week) plus rifapentine (300–900 mg/week), followed by isoniazid plus rifampicin (10 mg/kg/day) were ranked as best approaches with lower probabilities of disease incidence (10% and 19.5%, respectively in SUCRA) and death (20%). Higher doses of isoniazid monotherapy were significantly associated with more deaths (OR 18.28, 95% ICr [1.02, 48.60] of 4–6 mg/kg/day vs. 10 mg/kg/3x per week). Conclusions: Combined therapies of isoniazid plus rifapentine or rifampicin for short-term periods should be used as the first-line approach for treating LTBI in children and adolescents. The use of long-term isoniazid as monotherapy and at higher doses should be avoided for this population.
