Esophageal symptoms such as gastroesophageal reflux disease, dysphagia and motility disorders including ineffective esophageal motility (IEM), and absent contractility are common in scleroderma. We aimed to assess the association of nailfold capillaroscopy findings with high-resolution esophageal manometry (HRM) results in patients evaluated for scleroderma. Methods: This was a retrospective study of patients assessed for scleroderma who underwent both NVC and HRM at Mayo Clinic Florida from 2020 to 2024. We collected demographic information and data including rheumatologic diagnosis, NVC findings, and HRM results. Abnormalities assessed on NVC were those characteristics of the ‘scleroderma pattern’ including abnormal capillary density, capillary dilation, microhemorrhages, giant capillaries, ramified appearance, and disorganized appearance. HRM studies were classified by the Chicago Classification version 4.0 (CCv4.0) Results: Of 28 patients included patients, 16 (57.1 %) were women with a median age of 60 years (range 25-80) and 26 (92.9%) Caucasian. Rheumatological diagnoses included 8 scleroderma, 4 mixed connective tissue disease, 8 rheumatological process but not scleroderma, 8 not meeting criteria for a rheumatological disorder. On HRM, 7 (25.0%) were normal, 10 patients (35.7%) met CCv4.0 criteria for IEM, 5 (17.9%) absent contractility, 5 (17.9%) esophagogastric outflow obstruction (EGJOO), and 1 (3.6%) distal esophageal spasm (DES). By NVC, 9 (32.1%) of patients were normal, 11 (39.3%) abnormal, and 8 (28.6%) met criteria for scleroderma pattern (giant capillaries, microhemorrhages, loss of capillary density and abnormal shapes). Scleroderma pattern on NVC was not predictive of IEM classification (p=0.067), however the presence of microhemorrhages was correlated with >50% failed peristalsis on HRM (p=0.05). Discussion: In this study,a scleroderma pattern on NVC was not associated with esophageal dysmotility although this study may be limited by power. However, presence of microhemorrhages did associate with >50% failed peristalsis. These findings suggest that certain findings on nailfold capillaroscopy such as microhemorrhages may be useful to predict esophageal dysmotility and future research with larger patient cohorts are needed
