We read with great interest the article ‘Development and validation of the Scleroderma Clinical Trials Consortium Damage Index (SCTC-DI): a novel instrument to quantify organ damage in systemic sclerosis’ by Ferdowsi et al.1 We commend the authors’ to have come up with the much-needed concept of a damage index in systemic sclerosis. Differentiating activity from chronicity or damage is one of the key aspects in treatment of all rheumatological disorders and dictates the aggressiveness of treatment strategies employed.
