Background And Aim: Iloprost is recommend worldwide for the treatment of RP and the healing of DUs. The aim of this study is to report the regimens of Iloprost administered in different rheumatological centers within the same regional Health System Methods: A questionnaire exploring different items related to the use of Iloprost was developed and reviewed by three expert rheumatologists. The questionnaire was distributed as an online survey to all local SSc referral centers in Emilia-Romagna (Italy).

Redox sensitive human mitochondrial aconitase and its interaction with frataxin: In vitro and in silico studies confirm that it takes two to tango.

Mitochondrial aconitase (ACO2) has been postulated as a redox sensor in the tricarboxylic acid cycle. Its high sensitivity towards reactive oxygen and nitrogen species is due to its particularly labile [4Fe-4S] prosthetic group which yields an inactive [3Fe-4S] cluster upon oxidation. Moreover, ACO2 was found as a main oxidant target during aging and in pathologies where mitochondrial dysfunction is implied.

Pulmonary embolism and renal artery thrombosis in a patient with patent foramen ovale.

Background And Aim: Paradoxical embolism is a rare condition in which a thrombus migrates from the venous system to the arterial circulation, usually through a patent foramen ovale (PFO). Pulmonary embolism (PE) and isolated occlusion of one renal artery has been seldom reported.

Methods: We describe a case of a 47-year old white man with a one-month history of exertional dyspnea who was admitted to our hospital for  severe pain in the right lumbar region.

Instruments for Outcome Evaluation of Specific Domains in Primary Sjögren's Syndrome.

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disorder characterized by very heterogeneous features. The spectrum of this disorder may vary from benign but disabling symptoms such as dryness, due to lachrymal and salivary involvement, pain and fatigue, to systemic, potentially severe, manifestations that may involve any organ. In recent decades, the arrival of biotechnological therapy has offered new opportunities for the treatment of this-until now-orphan disease.

Management of Sjögren's Syndrome: Present Issues and Future Perspectives.

In view of the new possibilities for the treatment of primary Sjögren's syndrome (pSS) given by the availability of new biotechnological agents targeting the various molecular and cellular actors of the pathological process of the disease, classification criteria aimed at selecting patients to be enrolled in therapeutic trials, and validated outcome measures to be used as response criteria to these new therapies, have been developed and validated in the last decades. Unfortunately, the therapeutic trials so far completed with these new treatments have yielded unsatisfactory or only partially positive results. The main issues that have been evoked to justify the poor results of the new therapeutic attempts are: (i) the extreme variability of the disease phenotypes of the patients enrolled in the trials, which are dependent on different underlying patterns of biological mechanisms, (ii) the fact that the disease has a long indolent course, and that most of the enrolled patients might already have irreversible clinical features.

The Role of Interferons in the Pathogenesis of Sjögren's Syndrome and Future Therapeutic Perspectives.

There is a great deal of evidence pointing to interferons (IFNs) as being key cytokines in the pathogenesis of different systemic autoimmune diseases, including primary Sjögren's syndrome (pSS). In this disease, a large number of studies have shown that an overexpression of type I IFN, the 'so-called' type I IFN signature, is present in peripheral blood mononuclear cells, and that this finding is associated with the development of systemic extra-glandular manifestations, and a substantial production of autoantibodies and inflammatory cytokines. In contrast, the absence or a milder expression of type I IFN signature and low level of inflammatory cytokines characterizes patients with a different clinical phenotype, where the disease is limited to glandular involvement and often marked by the presence of widespread pain and depression.

High NEMO score values in nailfold videocapillaroscopy are associated with the subsequent development of ischaemic digital ulcers in patients with systemic sclerosis.

Background: Nailfold videocapillaroscopy (NVC) is a feasible method that allows the observation of the microvascular changes that mark the course of systemic sclerosis (SSc). In previous studies, we demonstrated that the NEMO score, i.e.

Impact of COVID-19 outbreak in an Italian cohort of patients with systemic sclerosis.

Background: Mortality rate in patients infected by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) can be related to the presence of comorbidities like diabetes, cardiovascular and pulmonary diseases. On the contrary, few data exist on the impact of CoronaVirus Disease 2019 (COVID-19) on patients with rheumatic disorders, namely in those having pulmonary involvement and treated with immunosuppressive agents. The present survey is aimed at knowing the impact of COVID-19 in a cohort of patients with systemic sclerosis (SSc).

The Model for Early COvid-19 Recognition (MECOR) Score: A Proof-of-Concept for a Simple and Low-Cost Tool to Recognize a Possible Viral Etiology in Community-Acquired Pneumonia Patients during COVID-19 Outbreak.

This study aims to assess the peripheral blood cell count "signature" of Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) to discriminate promptly between COronaVIrus Disease 19 (COVID-19) and community-acquired pneumonia (CAP). We designed a retrospective case-control study, enrolling 525 patients (283 COVID-19 and 242 with CAP). All patients had a fever and at least one of the following signs: cough, chest pain, or dyspnea.

Taking care of systemic sclerosis patients during COVID-19 pandemic: rethink the clinical activity.

COVID-19 outbreak has quickly spread worldwide, causing a high pressure on the health-care system. In Italy, from March 8, 2020, all the deferrable clinical activities have been suspended to increase the health care offer for COVID-19 patients. The hospital organization has been modified also in order to assure non-COVID-19 patients assistance.

Nailfold Videocapillaroscopy is a Useful Tool to Recognize Definite Forms of Systemic Sclerosis and Idiopathic Inflammatory Myositis in Interstitial Lung Disease Patients.

Nailfold videocapillaroscopy (NVC) is an easy tool used for the assessment of patients with Raynaud's phenomenon (RP) as possibly associated with systemic sclerosis (SSc). Recent insights have also highlighted its role in the diagnostic assessment of idiopathic inflammatory myopathies (IIMs). The aim of this study is to describe the diagnostic role of NVC in a series of 361 consecutive patients with interstitial lung disease (ILD).

Quantification of Ground Glass Opacities Can Be Useful to Describe Disease Activity in Systemic Sclerosis.

Interstitial lung disease (ILD) is the main cause of death in systemic sclerosis (SSc) patients. Usually, patients have lung involvement characterized by ground glass opacities (GGOs), but honeycombing (HC) is also possible. The Wells score is a semi-quantitative index, which is able to assess ILD by distinguishing its main components.

Patients with Interstitial Lung Disease Secondary to Autoimmune Diseases: How to Recognize Them?

The diagnostic assessment of patients with Interstitial Lung Disease (ILD) can be challenging due to the large number of possible causes. Moreover, the diagnostic approach can be limited by the severity of the disease, which may not allow invasive exams. To overcome this issue, the referral centers for ILD organized Multidisciplinary Teams (MDTs), including physicians and experts in complementary discipline, to discuss the management of doubtful cases of ILD.

Gene Expression Profiles in Primary Sjögren's Syndrome With and Without Systemic Manifestations.

Objective: To investigate the gene expression profile in patients with Sjögren's syndrome that is characterized by different clinical phenotypes.

Methods: RNA from peripheral blood mononuclear cells was purified in 8 patients with glandular features (GFs) and widespread pain (WP) and 11 with extraglandular manifestations (EGMs) and then was analyzed by hybridization on a human gene chip exploring more than 40,000 human genes. Differentially expressed genes (DEGs) in the two subgroups (ie, those with false discovery rate-corrected values ≤ 0.

NEMO score in nailfold videocapillaroscopy is a good tool to assess both steady state levels and overtime changes of disease activity in patients with systemic sclerosis: a comparison with the proposed composite indices for this disease status entity.

Background: In previous studies, we demonstrated that the NEMO score, i.e. the cumulative number of microhaemorrhages (MHEs) and microthromboses (MTs), observed in nailfold videocapillaroscopy was a good indicator of the steady state level of disease activity (DA) in patients with systemic sclerosis (SSc) when the European Scleroderma Study Group (EScSG) index was considered the gold standard.

Clinical, serological and radiological features of a prospective cohort of Interstitial Pneumonia with Autoimmune Features (IPAF) patients.

Background: The term Interstitial Pneumonia with Autoimmune Features (IPAF) describes patients with Interstitial Lung Diseases (ILDs) and clinical or serological features of autoimmune diseases insufficient to reach a specific classification of a Connective Tissue Disease (CTD). Currently, retrospective studies on IPAF patients have proven to be heterogeneous in general characteristics, outcomes and High-Resolution Computed Tomography (HRCT) pattern. This study aims to describe for the first time the clinical, serological and radiological features of a prospective cohort of IPAF patients.

Regional grafting of autologous adipose tissue is effective in inducing prompt healing of indolent digital ulcers in patients with systemic sclerosis: results of a monocentric randomized controlled study.

Background: A randomized controlled trial (RCT) was performed to confirm preliminary uncontrolled data indicating that regional adipose tissue (AT) grafting (G) is effective in inducing ischemic digital ulcer (IDU) healing in patients with systemic sclerosis (SSc).

Patients And Methods: SSc patients with IDUs were randomized to be blindly treated with AT-G or a sham procedure (SP). AT-G consisted of injection, at the base of the finger with the IDU, of 0.

Interstitial Lung Disease in patients with Polymyalgia Rheumatica: A case series.
