Background: There are few studies regarding the characteristics of mediastinal lymphadenopathy (MN) in patients with systemic sclerosis (SSc). Understanding its features could help radiologists interpret lung imaging more confidently.
Objective: To determine the prevalence and characteristics of MLN in patients with SSc and factors associated with MLN.
Material And Method: A retrospective review of medical records and high resolution computed tomography (HRCT) of the lungs of all patients with SSc at Srinagarind Hospital, Khon Kaen University, Thailand between 2009 and 2011 was done. Univariate and multivariate logistic regressions were used to analyze the outcomes.
Results: Sixty patients were eligible for the present study; the majority of them was women (71.7%) and had diffuse SSc (71.7%). The prevalence of MLN was 56.7% (36 in 60 cases). The distribution of MLN was mainly found in two or more locations (47.1%) and had isodensity on imaging (61.3%). The median size of nodes was 1.2 cm (inter-quartile range 1, 1.4 cm). Only the pulmonary fibrosis score was significantly associated with MLN with the adjusted odds ratio of 1.2 (95% confidence interval 1.1, 1.4, p = 0.03). There was no association between MLN with other factors.
Conclusion: MLN was prevalent in patients with SSc. The pulmonary fibrosis score was an independent factor associated with MLN.

Cardiac manifestations in systemic sclerosis (SSc) are variable and are associated with a poor prognosis, frequently resulting in impaired right ventricular function and heart failure. A high proportion of patients with SSc experience pulmonary arterial hypertension (PAH), interstitial lung disease, or myocardial involvement, all of which can lead to exercise intolerance. In this context, cardiopulmonary exercise testing (CPET) is a useful tool for diagnosing exercise intolerance, elucidating its pathophysiology, and assessing its prognosis.

Objective: To analyse work participation among patients with inflammatory rheumatic musculoskeletal diseases (iRMDs), namely rheumatoid arthritis (RA), axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and ANCA-associated vasculitis (AAV).
Methods: A cross-sectional sample of 16 421 patients from the National Database of the German Collaborative Arthritis Centers, aged <65 years were analysed. For each diagnosis, yearly rates of absenteeism, employment and disability pensions were analysed from 2010 to 2022.

Pulmonary arterial hypertension (PAH) is a complication of systemic sclerosis (SSc), and several screening algorithms have been proposed for the early detection of PAH in SSc. This study aimed to evaluate the predicting values of the DETECT algorithm for SSc-PAH screening in patients with SSc undergoing right heart catheterization (RHC) based on 2015 ESC/ERS echocardiographic criteria in a real-life setting. Patients fulfilling the 2013 ACR/EULAR classification criteria for SSc and with available data for PAH screening with the DETECT algorithm and the 2015 ESC/ERS echocardiographic criteria were retrospectively enrolled from January to June 2017 and then followed for 5 years.

Systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and idiopathic inflammatory myositis (IIM) are autoimmune diseases managed with long-term immunosuppressive therapies. Hu19-CD828Z, a fully human anti-CD19 chimeric antigen receptor (CAR) with a CD28 costimulatory domain, is engineered to potently deplete B-cells. In this study, we manufactured Hu19-CD828Z CAR T-cells from peripheral blood of SLE, IIM, and SSc patients and healthy donors (HDs).

Systemic sclerosis (SSc) is an immuno-inflammatory rheumatic disease that can affect both the skin and internal organs through fibrosis. Pulmonary arterial hypertension (PAH) is one of the most severe secondary complications. Structural changes in the vascular bed lead to increased pressures in the pulmonary circulation, severely impacting the right heart and significantly affecting mortality.
