Pauling JD, et al. - Researchers gauged the clinical associations of systemic sclerosis (SSc)-Raynaud's phenomenon (RP) symptom characteristics and evolution of SSc-RP symptoms with disease progression. Distinct patterns of SSc-RP were seen among patients. These patterns may relate to progression of the obliterative microangiopathy of SSc. Diary-based approaches to assessing SSc-RP could be influenced by the difficulty distinguishing discrete SSc-RP attacks from persistent digital ischaemia in advanced SSc.
