Exploring Nailfold Videocapillaroscopy in Children with Psoriatic Arthritis: Are There Any Hidden Vascular Signatures?

Objectives: Juvenile psoriatic arthritis (JPsA), a subtype of juvenile idiopathic arthritis, is a chronic inflammatory disease characterized by joint and skin involvement. Microvascular alterations, including endothelial dysfunction and inflammation, are thought to contribute to its pathophysiology. Nailfold videocapillaroscopy (NVC) is a non-invasive technique for assessing microvascular changes.
