ATM and systemic sclerosis: Prior research has demonstrated that abnormalities in capillary morphology can serve as predictive markers for the development of DUs, thereby emphasizing the utility of NVC in clinical assessments and as monitoring tool even after Ssc diagnosis, to better identify SSc patients at higher risk of DU [34].The well-documented association of DU with serum ATA [35, 36] reinforces the prognostic value of these clinical and serological parameters, hallmarks of more aggressive disease phenotypes [3, 15, 31].
