[Risk of infections associated with the use of biological medications; a review].

Biological medications are effective for the treatment of cancer and inflammatory diseases. The aim of this review is to summarize the available evidence in systematic reviews or meta-analyses about the risk of infection in patients with cancer, arthritis, psoriasis and inflammatory bowel disease who use biological medications. We included systematic reviews or meta-analyses of controlled clinical trials and case/control studies that analyze infections during and after treatment with FDA-approved biological medications for the treatment of cancer, arthritis, inflammatory bowel disease and psoriasis, both in adults and children.
