Background:
The goal of this study was to investigate whether ceftriaxone combination therapy is associated with better clinical outcomes than respiratory fluoroquinolone monotherapy for adults with community-acquired pneumonia (CAP). We conducted a meta-analysis of published studies.
Methods:
Using the PubMed, EMBASE, and Cochrane Library databases, we performed a literature search of available randomized controlled trials (RCTs) published as original articles before September 2017.
Results:
Nine RCTs, involving 1520 patients, were included in the meta-analysis. The pooled relative risks (RRs) for the efficacy of ceftriaxone combination therapy versus respiratory fluoroquinolones monotherapy were 0.96 (95% CI: 0.92-1.01), based on clinically evaluable populations, and 0.93 (95% CI: 0.88-0.99) based on intention-to-treat (ITT) populations. No statistically significant differences were observed in microbiological treatment success (pooled RR=0.99, 95% CI: 0.90-1.09), although drug-related adverse events were significantly lower with ceftriaxone combination therapy than with respiratory fluoroquinolones monotherapy (pooled RR=1.27, 95% CI: 1.04-1.55).
Conclusions:
Current evidence showed that the efficacy of ceftriaxone combination therapy was similar to respiratory fluoroquinolone monotherapy for hospitalized CAP patients, and was associated with lower drug-related adverse events.
