Special Issue Information

Dear Colleagues,

Systemic sclerosis (SSc) is a complex, multifaceted autoimmune disease characterized by vascular abnormalities, immune system dysregulation, and progressive fibrosis of the skin and internal organs. Despite significant strides in understanding the pathogenesis of SSc, it remains a challenging condition to diagnose and manage due to its heterogeneity and its variability in clinical manifestations.

The Special Issue “Recent Advances in Understanding Systemic Sclerosis” aims to highlight the latest research findings and clinical advancements in the field of SSc. Our goal is to provide a comprehensive overview of the current state of knowledge and to explore innovative therapeutic approaches that could improve patient outcomes.

Topics within the scope of this Special Issue include, but are not limited to, the following:

  • Diagnosis and assessment of SSc;
  • Pathophysiology of SSc;
  • The role of genetic and environmental factors in disease development;
  • Cutting-edge insights into the molecular mechanisms underlying fibrosis;
  • Novel and emerging therapies for SSc.

By bringing together leading experts and researchers, this Special Issue seeks to foster collaboration and stimulate further investigation into systemic sclerosis. We hope that the insights presented here will pave the way for improved diagnostic tools, more effective treatments, and ultimately, better quality of life for patients affected by this debilitating disease.

Background: Systemic sclerosis (SSc) represents a multidimensional disease affecting various organs and systems, with the common denominator being the vascular pathology encountered in the micro- and macrocirculation of SSc patients. Recently, much progress has been made toward understanding the molecular basis of endothelial injury and subsequent fibroblast activation, thus paving the way for specific therapy that can target and counteract these processes. Aim: In this review, we examined the latest preclinical and clinical data on therapeutic options to address vascular abnormalities in SSc. Results: We discuss the efficacy of current treatments, including pharmacological agents and emerging therapies, in mitigating vascular damage and improving patient outcomes based on preclinical models and clinical trials that offer evidence of their safety and effectiveness. Conclusions: Although promising therapeutic strategies emerge, optimizing the management of vascular abnormalities in SSc requires further research. Full article

Introduction: Calcinosis cutis (CC), the pathological deposition of calcium salts in the skin, is a frequent and challenging complication of systemic sclerosis (SSc). Despite its high prevalence, the underlying pathophysiology remains poorly understood, complicating treatment strategies. Material and Methods: This narrative review synthesizes the literature on CC in the context of SSc. The current understanding and treatment of CC in SSc is reviewed, focusing on the role of hypoxia in its pathogenesis and the therapeutic potential of sodium thiosulfate (STS). Results and Discussion: Research indicates a potential link between hypoxia and the development of CC in SSc, shedding light on novel pathogenic mechanisms. Additionally, promising results from treatments such as STS spurs interest in conducting larger, randomized controlled trials to validate these findings. Full article

Background: Interstitial lung disease (ILD) has replaced scleroderma renal crisis as the leading cause of mortality in systemic sclerosis (SSc), with a 10-year mortality of 40%. There have been well-powered randomised control trials (RCTs) demonstrating the effect of cyclophosphamide (CYC), mycophenolic acid (MMF), nintedanib and tocilizumab (TCZ) in SSc-ILD but a paucity of sufficiently powered studies investigating other agents in the disease. Methods: This is a narrative review which examines the existing evidence for immunosuppressive treatments, transplant and adjunctive therapies in SSc-ILD by reviewing the key landmark trials in the last two decades. Results: MMF for 2 years is as effective as oral CYC for 1 year. Rituximab (RTX) is non-inferior to CYC. TCZ appears to have a beneficial effective regardless of the extent of lung involvement. Conclusions: There is now a strong evidence base supporting the use of MMF as the first line option in SSc-ILD. RTX, CYC and TCZ are viable therapeutic options if there is ILD progression on MMF. Anti-fibrotic and pulmonary arterial (PAH) treatments likely add long-term synergistic benefits. There remains a role for lung transplantation in select patients. Full article

Systemic sclerosis (SSc) is a rare, multifactorial autoimmune disease characterized by widespread vascular damage and fibrosis. Pulmonary involvement is a significant manifestation of SSc, contributing to considerable morbidity and mortality. Therefore, identifying reliable biomarkers is of the utmost importance. This review explores emerging biomarkers to enhance diagnostic accuracy, prognostic assessment, and disease monitoring in SSc lung involvement. We discuss recent findings in immunological biomarkers, inflammatory indicators, and other parameters that can function as potential diagnostic and prognostic tools. A comprehensive understanding of these biomarkers could result in earlier and more accurate detection of pulmonary complications in SSc, aiding in timely intervention. Furthermore, we explore the advances in disease monitoring through innovative biomarkers, focusing on their roles in disease activity and treatment response. Integrating these novel biomarkers into current clinical practice and therapeutic protocols through clinical trials can revolutionize the management of SSc-related lung disease, ultimately improving patient outcomes and quality of life.
