SUMMARY
AimTo compare the effectiveness and safety of clindamycin ⁄ aminoglycoside with broad-spectrum b-lactam monotherapy in patients with intraabdominal infections by performing a meta-analysis of randomized controlled trials (RCTs).
MethodsThe relevant 28 RCTS were retrieved from PubMed searches and reviewed by two reviewers independently.Results b-lactam monotherapy was more effective regarding cure of the infection than clindamycin ⁄ aminoglycoside (3177 clinically evaluable patients, fixed effects model, OR = 0.67, 95% CI: 0.55-0.81). The same result was found in several subset analyses. There was no difference in all-cause mortality and attributable-to-infection mortality [2382 intention-to-treat (ITT) patients, fixed effects model, OR = 1.25, 95% CI: 0.74-2.11 and 1976 ITT patients, OR = 1.19, 95% CI: 0.59-2.41, respectively]. There was no difference regarding overall adverse events and ototoxicity (1460 ITT patients, OR = 1.05, 95% CI: 0.80-1.37, and 1404 ITT patients, OR = 3.22, 95% CI: 0.72-14.45, respectively). However, treatment with clindamycin ⁄ aminoglycoside was more likely to be associated with nephrotoxicity compared to b-lactam (3065 ITT patients, OR = 3.7, 95% CI: 2.09-6.57). Clindamycin ⁄ aminoglycoside was less likely to be associated with antibiotic-associated diarrhoea compared to b-lactam (3050 ITT patients, OR = 0.68, 95% CI: 0.46-1.00).
ConclusionThe results of our meta-analysis suggest that b-lactams are more effective in the treatment of intra-abdominal infections compared with clindamycin ⁄ aminoglycoside.
