Adding amynoglycoside to {beta} lactam does not improve results

In patients with neutropenia and sepsis, mortality when {beta} lactams and aminoglycosides are used together is no different from {beta} lactams used alone, but the risk of adverse effect is increased. Paul and colleagues (p 668) reviewed 64 trials with 7586 patients and found that the combination did not improve survival or reduce superinfection or colonisation rates; nephrotoxicity was more common with combination therapy. The overall quality of the studies was poor, the authors say, and it is of concern that studies comparing different {beta} lactams may not detect important harm to patients.
