Stiff skin syndrome: evidence for an inflammation-independent fibrosis?

Objectives. Stiff skin syndrome (SSS) is a rare scleroderma-like syndrome of unknown aetiology. A 16-year-old boy presented with thoracic and abdominal asymmetry, and ‘orange peel' cutaneous lesions, with fibrotic stone-hard indurations at the buttocks, thighs and arms leading to secondary joint contractures of the extremities. Our aim was to analyse the expression of extracellular matrix (ECM) molecules and pro-fibrotic cytokines in the dermis and epidermis of SSS. Methods. The diagnosis of SSS was confirmed by clinical and histopathological examination. Collagen type 1 alpha-2 chain (Col1A2), fibronectin-1, thrombospondin-1, TGF-β, connective tissue growth factor (CTGF), IL-6, -1β, ET-1, Fibroblast growth factor receptor 3 (FGFR-3) and MCP-1 expression was analysed in SSS and age- and sex-matched healthy control skin by real-time PCR. VEGF expression was also studied. Results. Histopathological examination showed flattened dermal papillae, a scarce presence of sub-epidermal microvessels and mild dermal fibrosis, but no inflammatory infiltrates. In the SSS dermis, the expression of IL-1β, -6 and MCP-1 was low, whereas VEGF was intensively expressed. No differences were observed for TGF-β, CTGF and ET-1. In contrast, col1A2, fibronectin-1 and thrombospondin-1 were overexpressed in the SSS dermis. Conclusion. In our SSS patient, an overexpression of ECM proteins was detected, whereas no inflammatory infiltrates or up-regulation of pro-fibrotic cytokines were found. The data suggest that fibrosis in SSS might be independent from inflammatio

Treatment Patterns and Pharmacoutilization in Patients Affected by Rheumatoid Arthritis in Italian Settings

This study aimed to evaluate the treatment patterns and pharmacoutilization of patients with rheumatoid arthritis (RA) in real-world settings in Italy. This retrospective observational analysis was based on administrative databases of selected Italian entities. All adult patients with RA diagnosis confirmed by ≥1 discharge diagnosis of RA (ICD-9-CM code = 714.0) or an active exemption code (006.714.0) were enrolled in 2019. Two cohorts were created: one included patients prescribed baricitinib, the other those prescribed biological disease-modifying antirheumatic drugs (bDMARDs). Overall, 47,711 RA patients were identified, most of them without DMARD prescription. As a first-line prescription, 43.2% of patients were prescribed conventional synthetic DMARDs (csDMARDs), 5.2% bDMARDs and 0.3% baricitinib. In 2019, 82.6% of csDMARD users continued with the same DMARD category, 15.9% had a bDMARD, while 1.5% had baricitinib as second-line therapy. Overall, 445 patients used baricitinib during 2019. During follow-up, baricitinib was prescribed as monotherapy to 31% of patients, as cotreatment with csDMARDs and corticosteroids to 27% of patients, with corticosteroids to 28% of patients and with csDMARDs to 14% of patients. In line with previous findings, a trend of bDMARD undertreatment was observed. The treatment patterns of baricitinib patients could help to better characterize patients eligible for new therapeutic options that will be available in the future
