Background: Raynaud’s phenomenon (RF) is a vasospastic condition characterized by episodic color changes of blanching, cyanosis, and hyperemia of the extremities of the body

Objectives: We aim to examine the clinical presentation, capillaroscopic findings and disease associations of Raynaud’s phenomenon (RP) in pediatric patients

Methods: We retrospectively enrolled a single-center cohort of 247 consecutive pediatric patients with RP admitted to Umraniye Training and Research Hospital, Pediatric Rheumatology Clinic, Istanbul, Turkey, since 2016. Medical records were analyzed for clinical presentation, disease associations, and physical examination and laboratory findings.

Results: We reported 247 patients (152 female, 95 male) with RP. Their mean age at disease onset was 14.5±2.55 years and median age at diagnosis was 15.4± 2.21 years. In patients with secondary RP syndrome (10.9%), the age of complaint was found to be lower than others (p=0.03). Although most patients have affected upper extremity (hand and fingers), lower extremity (toes) involvement was also detected in 50 (20%) patients. In both the patients with primary and secondary RP, main triggering factor was found as cold exposure. Biphasic (53.6%) color changes were more seen in primary RP, although triphasic (51.8%) color changes were more in patients with secondary RP (p=0.00). The presence of antinuclear antibodies and abnormal nailfold capillaries were more seen in patients with secondary RP (28% vs 74% and 35.3% vs 66.7, respectively p=0.00). Digital ulcer was detected 5.2% of patients (mostly secondary). Out of 247, 31 patients were treated with low-dose aspirin, 47 with calcium blockers, 25 with low-dose aspirin and calcium blockers, 16 with iloprost and/or bosentan, while the remaining 140 did not receive any drug.

Conclusion: Similar to adults, RP is more common in girls without an underlying disease. In patients with secondary RP, the symptoms. It has been shown that in patients with secondary RP, symptoms begin at a younger age and the ANA positivity and abnormal nailfold capillaries correlate.
