Abstract

Tranexamic acid (TXA) is an antifibrinolytic drug primarily used for reducing blood loss in patients with major bleedings. Animal and cell studies have shown that TXA might modulate the inflammatory response by either enhancing or inhibiting cytokine levels. Furthermore, recent human studies have found altered inflammatory biomarkers in patients receiving TXA when compared with patients who did not receive TXA. In this systematic review we investigated the effect of TXA on inflammatory biomarkers in different patient groups. A systematic literature search was conducted on the databases PubMed and Embase to identify all original articles that investigated inflammatory biomarkers in patients receiving TXA and compared them to a relevant control group. The review was performed according to the PRISMA guidelines, and the literature search was performed on November 29, 2021. Thirty-three studies were included, among which 14 studies compared patients receiving TXA with patients getting no medication, another 14 studies investigated different dosing regimens of TXA, and finally five studies examined the administration form of TXA. The present review suggests that TXA has an anti-inflammatory effect in patients undergoing orthopaedic surgery illustrated by decreased levels of C-reactive protein and interleukin-6 in patients receiving TXA compared with patients receiving no or lower doses of TXA. However, the anti-inflammatory effect was not found in patients undergoing cardiac surgery, pediatric craniosynostosis patients, or in rheumatoid arthritis patients. The inflammatory response was not affected by administration form of TXA (oral, intravenous, or topical). In conclusion, an anti-inflammatory effect of TXA was consistently found among orthopaedic patients only.
