Development and initial validation of the Localized Scleroderma Skin Damage Index and Physician Global Assessment of disease Damage: a proof-of-concept study

Abstract: To complete the LS Cutaneous Assessment Tool (LoSCAT), we developed and evaluated the psychometric properties of the LoSDI and PGA-D in addition to the LS Skin Severity Index (LoSSI). These instruments will facilitate evaluation of LS patients for individual patient management and clinical trials. LoSDI and PGA-D demonstrated excellent reliability and high validity. LoSCAT provides an improved understanding of LS natural history. Further study in a larger group of patients is needed to confirm these preliminar… Show more

“…Skin induration is estimated on the basis of palpation of the peripheral section of the lesions and the ability to pinch the skin into a fold: 0 -skin unaffected/easy to move; 1 -mild increase in thickness/ skin normal to move; 2 -moderate increase in thickness, skin difficult to move/pinch into a fold; 3 -severe thickness/impossible to pinch skin into a fold. (Skin thickness at the margin is considered to be secondary to inflammatory process and indicate active disease stage; in contrast, skin thickness at the centre of a lesion is a consequence of excessive collagen deposition and reflects tissue damage) [44]. Emergence of new lesions or enlargement of pre-existing lesions within the past month is scored 3, and if the features are absent, a 0 score is given.…”
