Nailfold Videocapillaroscopy Alterations in Dermatomyositis and Systemic Sclerosis: Toward Identification of a Specific Pattern.

Objective: The term scleroderma pattern typically defines capillary abnormalities of scleroderma spectrum disorders, mainly systemic sclerosis (SSc) and dermatomyositis (DM). Our study aimed to investigate differences in nailfold videocapillaroscopy (NVC) between DM and SSc, with a cross-sectional and longitudinal evaluation.

Methods: NVC features of 29 consecutive patients with DM were compared with 90 patients with SSc categorized into the 3 subsets of scleroderma pattern: early, active, and late.

Prevalence and evolution of scleroderma pattern at nailfold videocapillaroscopy in systemic sclerosis patients: Clinical and prognostic implications.

Background: Microvascular involvement plays a decisive role in systemic sclerosis (SSc) pathogenesis occurring early in the course of the disease. Microangiopathy is responsible of important clinical manifestations, such as Raynaud's phenomenon, digital ulceration, and pulmonary arterial hypertension. Typical microvascular alterations, called scleroderma pattern, are detectable at nailfold capillaroscopy in a significant percentage of SSc patients; however its prevalence is highly variable in published studies.

Large Vessel Vasculitis Occurring in Rheumatoid Arthritis Patient under Anti-TNF Therapy.

Vasculitis is a heterogeneous group of disorders characterized by the presence of necrotic inflammatory phenomena and destruction of blood vessels. Vasculitis is classified as primary (idiopathic) or secondary to infections, connective tissue diseases and drugs but can also be considered as a paraneoplastic phenomenon. Evidence shows that the increasing use of biological agents results in a growing number of reports of autoimmune diseases induced by these therapies.
