AimsProstanoids are indicated in the treatment of peripheral arterial disease (PAD). Available trials suggest that these compounds could reduce the symptoms of intermittent claudication, even though the quality of studies is poor. The present meta-analysis is aimed at verifying the effects of prostanoids on amputation rate and ulcer healing in patients with lower limb PAD.Materials and methodsThe review protocol was published on http://www.crd.york.ac.uk/prospero (CRD42015020258). A comprehensive search for published and unpublished trials comparing iloprost, alprostadil, prostaglandin-E1, epoprostenol, or taprostene with placebo/no therapy on amputation rate in patients with PAD and ulcer healing rate in patients with concomitant foot ulcers. Mantel–Haenzel odds ratio (MH-OR) was calculated with random effect models for the chosen endpoints.ResultsA total of 18 trials, enrolling 3,077 and 2,763 patients in the prostanoid and comparator groups, respectively were included in the analysis. Only 11 and 10 of those trials reported data on total and major amputations, respectively. Prostanoids were associated with a significantly lower risk of major (MH-OR [95% confidence interval] was 0.77 [0.63; 0.93], p = 0.007), but not total, amputations. Healing rate (available only in 7 trials) was not significantly augmented by prostanoid treatment.ConclusionsAvailable data are not sufficient to support an extensive use of prostanoids in patients with critical limb ischemia, as an adjunct to revascularization or as an alternative to major amputation in cases which cannot undergo revascularization.
