Objective:

To assess current best evidence available to generate recommendations regarding the effectiveness and safety of tigecycline use in adults with skin and soft-tissue infections (SSTIs).

Materials and methods:

A systematic review of the literature was conducted by selecting meta-analyzes and controlled clinical trials (CCTs), which were assessed using the SIGN tool (Scottish Intercollegiate Guidelines Network) in order to generate evidence tables according to GRADE of studies of tigecycline in the SSTIs indication, and then using a modified Delphi Method to score the different recommendations.

Results:

Nine meta-analyzes were included compounded by five randomized clinical trials with a sample size of 1873 patients, where 952 patients were assigned to tigecycline. The group of patients with tigecycline showed no inferiority to the comparator in clinical cure (RR = 0.76 95% CI 0.57 - 1.03), microbiologic cure (RR = 0.92 95% CI 0.61 - 1.38), serious adverse events RR 1, 41 (95% CI 0.97 to 2.35) or mortality RR 1.9 (95% CI 0.84 to 4.3). Tigecycline may be related to increased frequency of minor adverse events of gastrointestinal origin.

Conclusion:

In adult patients with SSTIs, it is considered that the use of tigecycline in monotherapy in non-critically ill patients is equivalent in effectiveness to other antimicrobial treatment options. It should be especially considered as an adjustment therapy in patients with polymicrobial infections.
