Clinical Measures

Objective.We evaluated endothelin (ET)-1 plasma levels and some clinical measures in patients with primary Raynaud’s phenomenon (PRP), and in patients with systemic sclerosis (SSc) and secondary RP (SRP), in the latter according to their different nailfold videocapillaroscopy (NVC) patterns of microangiopathy (early, active, and late).Methods.Ninety-nine patients with SSc, 49 with PRP, and 45 control subjects were studied. NVC was performed in all patients to distinguish the pattern of microvascular damage, and the morphological alterations were scored by a semiquantitative rating scale. ET-1 plasma levels were evaluated in all individuals by ELISA.Results.ET-1 plasma levels were significantly higher (p = 0.001) in patients with both PRP and SRP, compared to controls. A significant positive correlation (p = 0.03) was found between ET-1 plasma levels and SRP duration, but not between ET-1 plasma levels and PRP duration. Significant correlations were observed in patients with SSc between ET-1 plasma levels and clinical measures (e.g., digital ulcers), as well as the score value of single NVC measures, such as the number of capillaries, “ramified” capillaries, and enlarged capillaries (p < 0.05). Finally, the highest ET-1 plasma levels were found in patients with SSc showing the late pattern of microangiopathy when compared to the early pattern (p = 0.03) and to controls (p = 0.003).Conclusion.Highest ET-1 plasma levels were detected in the more advanced stage of the SSc microangiopathy, namely the late NVC pattern, characterized by capillary loss and increased tissue fibrosis; this might support the involvement of ET-1 in the progression of the microvascular/fibrotic SSc damage.

Scleroderma Pattern

Background:Nailfold videocapillaroscopy (NVC) abnormalities in subjects with isolated Raynaud’s phenomenon (RP) may be present before transition to secondary RP(SRP) and development of a NVC “scleroderma pattern” and are known to predict for evolution to a connective tissue disease (CTD) within few years [1]. In a previous study, we have demonstrated that the very early increase of capillary diameter over 30 μm is an independent predictor for development of Systemic Sclerosis (SSc) associated SRP [2].Objectives:Present pilot retrospective study aimed to investigate in a cohort of patients affected by CTD–related RP the presence of very early capillaroscopic morphological and quantitative abnormalities in the acquired pictures of NVC performed before the development of the NVC scleroderma-pattern. In particular, the study was addressed to identify a “very early”scleroderma pattern, in order to intercept patients with RP at high risk of evolution in a CTD, specifically SSc.Methods:We selected the NVCs of 273 SSc patients presenting one of the validated NVC “scleroderma patterns”. We enrolled 26 SSc patients having a NVC analysis performed before the development ofthe “very early”NVC pattern. As controls, we evaluated 26 patients affected by other CTDs with stable non-scleroderma pattern over time. The 16 images per patient obtained by NVC examination were analyzed for total number of capillaries, number and the limbs diameters of capillaries with a diameter >30 μm, and microhemorrhages. Statistical analysis was performed using non-parametric tests.Results:All 26 SSc patients showed dilated capillaries with a diameter >30 μm in their previous NVC. Patients later developing scleroderma pattern had statically higher number and percentage of capillaries with a diameter >30 μm (p=0.0004 and p=0.0005), as well as a larger apical dilatation >40 μm (p=0.002). A progressive and significant increase in all capillary diameters were only detected in patients later diagnosed for SSc (apical p=0.006, venous p=0.02, arterial p=0.03). A significant homogeneous and progressive dilation was observed from the apical region and then involving both venous and arterial branches, only in SSc patients (p=0.002).Conclusion:Present pilot study demonstrates, for the first time that, before to develop a validated NVC scleroderma-pattern, all potential SSc patients present significant very early morphological and quantitative NVC changes. In particular, the progressive and homogeneous capillary loop dilation over 40 μm in over 40% of total number capillaries significantly could contribute to identify RP patients who will develop a SSc pattern after 4-5 years.References:[1]Cutolo M, Sulli A, Pizzorni C, Accardo S.

Flow Mediated Dilatation

Previous studies have shown that patients with Raynaud’s phenomenon secondary to systemic sclerosis present abnormal endothelial function; the mechanisms responsible for the endothelial dysfunction are unknown but increased vascular oxidative stress could be a possible cause. The hypothesis that a potent water-soluble antioxidant can reverse endothelial dysfunction in these patients was tested in the present study. We examined 11 female patients with Raynaud’s phenomenon secondary to systemic sclerosis and ten healthy control women by ultrasound imaging of the brachial artery to assess flow-mediated (endothelium-dependent) and nitrate-induced (endothelium-independent) vasodilatation. Flow-mediated dilatation and nitrate-induced dilatation were significantly reduced in patients with Raynaud’s phenomenon, indicating abnormal endothelial and smooth muscle cell function. Patients with Raynaud’s phenomenon entered a double-blind, randomized, crossover placebo-controlled trial and received orally 2 g of ascorbic acid or placebo; vascular studies were repeated two hours after ascorbic acid or placebo administration. Flow-mediated dilatation did not improve after ascorbic acid (1.6 ± 2.2% to 2.2 ± 2.5%, ns) or placebo administration (1.2 ± 1,9% to 1.7 ± 1.4%, ns); also nitrate-induced dilatation was similar after ascorbic acid or placebo (16 ± 7.4% vs 17 ± 8%, ns), suggesting no effect of ascorbic acid on endothelial and vascular smooth muscle function. In conclusion, ascorbic acid does not reverse endothelial vasomotor dysfunction in the brachial circulation of patients with Raynaud’s phenomenon secondary to systemic sclerosis. The use of different antioxidants or different dosing of ascorbic acid may be required to show a beneficial effect on endothelial vasodilator function.
