Safety of azithromycin in pediatrics: a systematic review and meta-analysis.

ABSTRACT: PURPOSE:To evaluate the toxicity of azithromycin in neonates, infants, and children. METHODS:A systematic review was performed for relevant studies using Medline (Ovid), PubMed, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, and International Pharmaceutical Abstracts. We calculated the pooled incidence of adverse drug reactions (ADRs) associated with azithromycin based on prospective studies (RCTs and prospective cohort studies) and analyzed the risk difference (RD) of ADRs between azithromycin and placebo or other antibiotics using meta-analysis of RCTs. RESULTS:We included 133 studies with 4243 ADRs reported in 197,675 neonates, infants, and children who received azithromycin. The safety of azithromycin as MDA in pediatrics was poorly monitored. The main ADRs were diarrhea and vomiting. In prospective non-MDA studies, the most common toxicity was gastrointestinal ADRs (938/1967; 47.7%). The most serious toxicities were cardiac (prolonged QT or irregular heart beat) and idiopathic hypertrophic pyloric stenosis (IHPS). Compared with placebo, azithromycin did not show increased risk ADRs based on RCTs (risk difference -?0.17 to 0.07). The incidence of QT prolonged was higher in the medium-dosage group (10-30 mg/kg/day) than that of low-dosage group (??10 mg/kg/day) (82.0% vs 1.2%). CONCLUSION:The safety of azithromycin as MDA needs further evaluation. The most common ADRs are diarrhea and vomiting. The risk of the most serious uncommon ADRs (cardiac-prolonged QT and IHPS) is unknown.

Project description:BackgroundMalaria is a major cause of morbidity and mortality in pediatrics in malaria endemic areas. Artemisinin-based combination therapies (ACTs) are the drugs of choice for malaria management particularly across malaria-endemic countries. This systematic review and meta-analysis was performed to assess efficacy and safety of ACTs for uncomplicated malaria in pediatric populations.MethodsA body of evidence was searched for published ACT trials until March 06, 2020. The search was focused on efficacy and safety studies of ACTs for uncomplicated malaria in pediatrics. PubMed library was searched using best adapted search terms after multiple trials. References were exported to the endnote library and then to Covidence for screening. Data was extracted using the Covidence platform. The per-protocol analysis report for the efficacy and the intention-to-treat analysis for the safety were synthesized. Met-analysis was carried using Open Meta-Analyst software. Random effects model was applied and the heterogeneity of studies was evaluated using I2 statistic.ResultsNineteen studies were included in the final analysis. Overall, crude, PCR-corrected P. falciparum malaria treatment success rate was 96.3 and 93.9% for day 28 and 42, respectively. In the subgroup analysis, PCR-corrected adequate clinical and parasitological response (ACPR) of dihydroartemisinin-piperaquine (DP) was 99.6% (95% CI: 99.1 to 100%, I2 = 0%; 4 studies) at day 28 and 99.6% (95% CI of 99 to 100%, I2 = 0%; 3 studies) at day 42. Nine studies reported ACT related adverse drug reactions (ADR) (8.3%, 356/4304). The reported drug related adverse reactions ranged from 1.8% in DP (two studies) to 23.3% in artesunate-pyronaridine (AP). Gastrointestinal symptoms were the most common ACT related adverse effects, and all ADRs were reported to resolve spontaneously.ConclusionACTs demonstrated a high crude efficacy and tolerability against P. falciparum. The high treatment success and tolerability with low heterogeneity conferred by DP has implication for policy makers who plan the use of ACTs for uncomplicated falciparum malaria treatment in pediatrics.

Project description:Vancomycin and teicoplanin are the glycopeptides currently in use for the treatment of infections caused by invasive beta-lactam-resistant gram-positive organisms. We conducted a systematic review and meta-analysis of randomized controlled trials that have compared vancomycin and teicoplanin administered systemically for the treatment of suspected or proven infections. A comprehensive search of trials without year, language, or publication status restrictions was performed. The primary outcome was all-cause mortality. Two reviewers independently extracted the data. Risk ratios (RRs) with 95% confidence intervals (CIs) were pooled by using the fixed-effect model (RRs of >1 favor vancomycin). Twenty-four trials were included. All-cause mortality was similar overall (RR, 0.95; 95% CI, 0.74 to 1.21), and there was no significant heterogeneity. In trials that used adequate allocation concealment, the results favored teicoplanin (RR, 0.82; 95% CI, 0.63 to 1.06), while in trials with unknown methods or inadequate concealment, the results favored vancomycin (RR, 3.61; 95% CI, 1.27 to 10.30). The latter trials might have recruited more severely ill patients. No other variable affected the RRs for mortality, including the assessment of glycopeptides administered empirically or for proven infections, neutropenia, the participant's age, and drug dosing. There were no significant differences between teicoplanin and vancomycin with regard to clinical failure (RR, 0.92; 95% CI, 0.81 to 1.05), microbiological failure (RR, 1.24; 95% CI, 0.93 to 1.65), and other efficacy outcomes. Lower RRs (in favor of teicoplanin) for clinical failure were observed with a lower risk of bias and when treatment was initiated for infections caused by gram-positive organisms rather than empirically. Total adverse events (RR, 0.61; 95% CI, 0.50 to 0.74), nephrotoxicity (RR, 0.44; 95% CI, 0.32 to 0.61), and red man syndrome were significantly less frequent with teicoplanin. Teicoplanin is not inferior to vancomycin with regard to efficacy and is associated with a lower adverse event rate than vancomycin.
