Chemical and carcinogenic risk in workplace are linked to an increase of the incidence of cancer in exposed workers. The aim of this observational study was to identify an association between exposure to chemical risk and changes in hematochemical parameters of workers exposed. The study examined blood count parameters performed on 4523 employees of Sapienza University of Rome from September 2019 to February 2020.

Background: Lung ultrasound (LUS) is a promising tool for detecting SSc-associated interstitial lung disease (SSc-ILD). Currently, consensus on the best LUS findings and execution technique is lacking.
Objectives: To compare qualitative and quantitative assessment of B-lines and pleural line (PL) alterations in SSc-ILD with chest CT analysis.
CXCL4 is an important biomarker of systemic sclerosis (SSc), an incurable autoimmune disease characterized by vasculopathy and skin/internal organs fibrosis. CXCL4 contributes to the type I interferon (IFN-I) signature, typical of at least half of SSc patients, and its presence is linked to an unfavorable prognosis. The mechanism implicated is CXCL4 binding to self-DNA, with the formation of complexes amplifying TLR9 stimulation in plasmacytoid dendritic cells (pDCs).

Chemokine (C-X-C motif) ligand 4 (CXCL4) is an early SSc biomarker that predicts worse disease outcome. We previously reported that CXCL4 is an autoantigen in SSc, and anti-CXCL4 antibodies correlated with IFN-I and were more abundant in patients with lung fibrosis.

Bioindicator(s) of SSc onset and progress are still lacking and the therapeutic approach remains a challenge. The T helper 1 (Th1) chemokine interferon (IFN)γ-induced protein 10 (IP-10/CXCL10) associates with disease progression and worse prognosis.

Methods: A cohort study was carried out on 114 SSc patients referred to our Scleroderma Clinic, matched for sex and age. Twenty-eight of them had missed scheduled examinations during the October 2020-March 2021 period and 86 has attended regular outpatient visits during the same period.
Chemokine (C-X-C motif) ligand 4 (CXCL4) is a biomarker of unfavorable prognosis in Systemic Sclerosis (SSc), a potentially severe autoimmune condition, characterized by vasculitis, fibrosis and interferon (IFN)-I-signature. We recently reported that autoantibodies to CXCL4 circulate in SSc patients and correlate with IFN-α. Here, we used shorter versions of CXCL4 and CXCL4-L1, the CXCL4 non-allelic variant, to search for autoantibodies exclusively reacting to one or the other CXCL4 form.

Moreover, when bound to "self" nucleic acids, LL37 acts as "danger signal," leading to type I interferon (IFN-I)/pro-inflammatory factors production. T-cell epitopes derived from citrullinated-LL37 act as better antigens than unmodified LL37 epitopes in SLE, at least in selected HLA-backgrounds, included the SLE-associated HLA-DRB1*1501/HLA-DRB5*0101 backgrounds.

Patients affected by systemic sclerosis (SSc) experienced constant fear because of their immunocompromised status. The aim of this study was to investigate the prevalence of SARS-CoV-2 infection and to analyze the lifestyle changes in a single-center cohort of SSc patients and if these changes were more severe than in the general population.

Before clinical manifestations of cardiovascular disease (CVD) occur, subclinical ATS can be investigated in different ways.
Aim: To evaluate the presence of subclinical ATS in a group of patients with SSc, and to identify different risk profiles among patients.
Systemic sclerosis (SSc) is characterized by skin/internal organ fibrosis, vasculopathy and autoimmunity. Chemokine (C-X-C motif) ligand 4 (CXCL4) is an SSc biomarker, predicting unfavorable prognosis and lung fibrosis. CXCL4 binds DNA/RNA and favors interferon (IFN)-α production by plasmacytoid dendritic cells (pDCs), contributing to the type I IFN (IFN-I) signature in SSc patients.
View Article and Find Full Text PDFSystemic sclerosis (SSc) is a chronic autoimmune disease characterized by fibrosis and vasculopathy. CXCL4 represents an early serum biomarker of severe SSc and likely contributes to inflammation via chemokine signaling pathways, but the exact role of CXCL4 in SSc pathogenesis is unclear. Here, we elucidate an unanticipated mechanism for CXCL4-mediated immune amplification in SSc, in which CXCL4 organizes "self" and microbial DNA into liquid crystalline immune complexes that amplify TLR9-mediated plasmacytoid dendritic cell (pDC)-hyperactivation and interferon-α production.

The inclusion of NC specific abnormalities increases the sensitivity of both 2013 ACR/EULAR and VEDOSS (Very Early Diagnosis of Systemic Sclerosis) classification criteria. We aimed to detect NC features able to predict progression toward established SSc in VEDOSS patients.

Methods: We enrolled 31 patients with SSc, randomly allocated to the occupational group (15 patients) or to the control group (16 patients). Each patient received specific outcome measures: Canadian Occupational Performance Measure (COPM), HAQ, Short-Form Health Survey (SF-36), Duruoz Hand Index (DHI), reassessed after 1 (T1) and three months (T2).
Objective: Pulmonary arterial hypertension (PAH) is a complication of SSc due to increased vascular resistance, and abnormal vascularity is a well-known feature of the disease as shown by nailfold videocapillaroscopy (NVC). This study investigated for specific NVC changes in SSc patients with and without PAH to assess any useful difference.
Methods: Twenty-four SSc patients, 12 with PAH and 12 without, entered the study.
Introduction: Digital ulcers (DU) occur in about 50% of systemic sclerosis (SSc) patients. Scleroderma DU are responsible for chronic pain and disability with the need of systemic and local treatments. Recently, capillaroscopic skin ulcer risk index (CSURI) has been validated as useful tool in predicting the appearance of new scleroderma ulcers and/or persistence of non-healing lesions, within 3 months from capillaroscopy evaluation.

Methods: Hand and wrist joints of 46 consecutive SSc patients and 15 healthy controls were studied by using PDUS. Each joint was evaluated for the presence of effusion, synovial hypertrophy, hyperaemia, bone erosions and cortical irregularities; in addition, local tendons for tenosynovitis and hyperaemia, and median nerve for entrapment neuropathy were examined.
Objectives: Systemic Sclerosis (SSc) is characterized by a microvascular damage due to an impairment of different angiogenic and angiostatic factors. Aim of this study was to measure plasma levels of nine molecules involved in these vascular processes in a group of SSc patients, respect to healthy controls (NC).
Methods: Sixty-five patients (M/F = 2/63; mean age = 57.
