    Abstract

    Introduction: Nailfold videocapillaroscopy is a non-invasive tool for the assessment of peripheral microcirculation, the main indication is the study of Raynaud's phenomenon, poorly standardized outside of this context. There is no clear information in real-life about the reasons for referral, the presence of clinical findings of autoimmune diseases, the frequency of patterns of autoantibodies, and specific capillaroscopic findings. Objective: The purpose of this survey is to describe the sociodemographic, clinical, paraclinical, and angioscopy findings of a cohort of subjects referred to a capillaroscopy service in North-western Colombia. Methods: A retrospective study was conducted, from 2015 to 2018. Categorical variables were expressed in frequency and percentage and quantitative variables in mean and standard deviation or median with interquartile range, depending on the distribution of the data. Results: A total of 318 capillaroscopies were performed for the first time. The main referral reason was Raynaud‘s phenomenon (n=134; 42.1%). The most frequent baseline capillaroscopic pattern found was normal (n=123; 38.7%). Of the 12 capillaroscopies that presented a non-specific pattern at a 6-month follow-up, only one (8.3%) progressed to a scleroderma pattern. In the subjects with systemic sclerosis, the most frequent clinical finding was sclerodactyly (n=34; 37.8%), and 42/44 individuals (95.4%) had positive antinuclear antibodies; the most frequent pattern was centromere (n=27; 64.3%). Conclusions: In a real-world setting, the main referral reason for capillaroscopy was Raynaud‘s phenomenon; more than a third of the subjects had normal capillaroscopic findings. Sclerodactyly was the most frequent clinical finding in patients with scleroderma capillaroscopic pattern.
