The earliest clinical manifestation of SSc is usually Raynaud's phenomenon, a small-arteries vasospasm driven by vascular tone dysregulation and microcirculatory abnormalities, resulting in digital ulcers (DU) in up to 50% of patients. Many cytokines as well as growth factors have been shown to play a role in promoting vascular smooth muscle cell proliferation and fibroblast activation, leading to ischemic damage as well as skin fibrosis. We aim to investigate a possible difference in venous and arterial blood levels of many cytokines (Th1- and Th17-related), GM-CSF, and endothelin-1 (ET1) in patients with and without DU. In the same patients, the correlations between capillary damage, evaluated by nailfold videocapillaroscopy (NVC), extension of skin fibrosis, calculated by modified Rodnan skin score (mRSS), and cytokines, ET-1, and GM-CSF levels were also measured. Patients with DU showed venous levels of IL-1β (p=0.024), IL-6 (p=0.012), IL-22(p=0.006), and TGF-β (p=0.046) significantly higher compared to arterial levels and arterial levels of GM-CSF and TNF-alpha significantly higher compared to venous levels (p<0.001). NVC abnormalities were correlated with arterial TNFa and venous IL22, IL23, and IL17 levels and negatively correlated with venous ET-1 levels, whereas mRSS showed a negative correlation with IL-21(ρ = −0.427, p=0.050). The increased Th17-cytokine levels in venous compared to arterial blood of patients with DU suggest local cytokine production on ulcer site. The higher TNFa and GM-CSF levels in arterial blood of DU patients support the attempt to mitigate the hypoxic damage, and the correlation between Th17-cytokines, mRSS, NVC, and ET1 agrees with the potent profibrotic stimulus at the onset of the disease, which decreases as the SSc progresses.

Hand functioning is often impaired in patients with Systemic sclerosis. Neuromuscular Taping is a novel application of tape able to improve functioning. The aim of this study was to evaluate the possible role of this application in the hand functionality of patients with Systemic sclerosis. Women with a diagnosis of SSc has been recruited and evaluated using different scales before and immediately after NMT application and after one, three and six months. Fifty-three women has been evaluated and Cochin Hand Functional Disability scale, Hand Mobility in Sclerodermia, Modified Rodnan Skin Score and Dreiser Algo - Functional Index scores showed statistical significant differences during all the period; moreover a reduction of pain and Raynaud Phenomenon's and an improvement of finger flexion has been observed. Application of NMT in patients with Systemic sclerosis have showed beneficial effect and future studies are needed to confirm these results. [ABSTRACT FROM AUTHOR]

The outbreak of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, causing coronavirus disease 2019 (COVID-19), has had a deleterious effect on the delivery of care for all acute and chronic medical conditions ([[1]]). Despite some patients complaining of symptoms potentially related to COVID-19, only one was referred to the emergency department and was admitted to the hospital after confirmation of COVID-19 pneumonia. Our findings do not allow any conclusions to be drawn about the real incidence rate of COVID-19 in SSc; however, according to our data, SSc patients seem not to be at increased risk for developing severe COVID-19.
