Psoriatic arthritis is an inflammatory arthritis without a clear etiology. Biological therapy has become key for its treatment, especially in more severe cases. There are several alternatives for biological treatment, including secukinumab. However, it is not clear how effective and safe it is, which is particularly relevant considering its high cost.To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach.We identified eight systematic reviews including three randomized trials overall. We concluded secukinumab in psoriatic arthritis leads to an improvement of disease activity and symptoms, and it is probably not associated to severe adverse events.
