Updates in the diagnosis and management of Takayasu's arteritis

Takayasu's arteritis is a rare, chronic, large vessel vasculitis which affects the aorta and its large branches. Early diagnosis is important to prevent serious end organ damage, including to stroke and ischemic heart disease. Studies have demonstrated treatment response with methotrexate, azathioprine, and tumor necrosis factor (TNF) inhibitors. This article aims to describe to the reader key features of Takayasu's arteritis and highlights updated evidence in the diagnosis and management of these patients. We also review the 2021 ACR guidelines for Takayasu's arteritis and correlate them to the updated evidence discussed throughout the review. An extensive literature search was conducted via PUBMED, including the words 'Takayasu's diagnostic criteria,' 'Takayasu's treatment,' 'Takayasu's diagnosis,' 'Takayasu's imaging', and 'Takayasu's diagnostic criteria.' Search was filtered to include clinical trials, randomized controlled trials, systematic reviews, and meta-analyses. Articles in the English language or with English translation and published by the date of 20 December 2021 were included.
