Objective: This review aims to provide an estimate of sarcopenia prevalence and its impact on clinical characteristics in patients with systemic sclerosis (SSc).
Design: Systematic review and meta-analysis.
Data Sources: Embase, Medline, Web of Science and the Cochrane Central Register of Controlled Trials were systemically searched from inception to 24 May 2023.
Eligibility Criteria For Selecting Studies: We included observational studies that reported the prevalence of sarcopenia in patients with SSc.
Data Extraction And Synthesis: Two reviewers independently performed study selection and data extraction using standardised methods. Risk of bias was assessed using the Agency for Healthcare Research and Quality Scale and the Newcastle-Ottawa Scale. Meta-analysis was conducted using random effects models.
Results: A total of 4583 articles were screened and 9 studies with data from 815 patients were included in the analysis (8 cross-sectional studies and 1 retrospective cohort study). The overall prevalence of sarcopenia in patients with SSc was 22% (95% CI 17% to 28%). Patients with SSc with sarcopenia had a poorer quality of life (mean difference -12.02; 95% CI -19.11 to -4.93) and higher C reactive protein (CRP) levels (standardised mean difference 0.67; 95% CI 0.35 to 1.00).
Conclusions: Sarcopenia is common in patients with SSc. Patients with SSc with sarcopenia had a worse quality of life and higher CRP levels, based on our findings. Given the detrimental impact of sarcopenia on quality of life, future efforts aimed at early identification of sarcopenia in the clinical assessment of patients with SSc may have significance.

Autoimmune pulmonary alveolar proteinosis developed during treatment for systemic sclerosis: a case report.

Background: Reports of autoimmune diseases coexisting with autoimmune pulmonary alveolar proteinosis (autoimmune PAP; APAP) are extremely rare. APAP coexisting with autoimmune diseases may often be misdiagnosed as connective tissue disease-associated interstitial lung disease (ILD). Here, we describe a rare case of a patient with systemic sclerosis who was diagnosed with APAP after the exacerbation of lung opacities during treatment with immunosuppressive agents.

Objective: Early personalized identification of systemic sclerosis (SSc) patients at risk for scleroderma renal crisis (SRC) can help provide better treatment and improve outcomes. This study aimed to create and validate a new multi-predictor nomogram to predict SRC risk and compare it to an existing model.
Methods: A retrospective multicentre observational study was conducted using clinical data from SSc patients with SRC registered in the Chinese Rheumatism Data Center (CRDC) database.
Role of Exercise Stress Echocardiography in Systemic Sclerosis: Pathophysiological and Prognostic Significance of the Systemic Sclerosis with a Heart Failure and Preserved Ejection Fraction Phenotype.

Aims: Left ventricular (LV) diastolic dysfunction and heart failure with preserved ejection fraction (HFpEF) are common cardiac complications of patients with systemic sclerosis (SSc). Exercise stress echocardiography is often used in symptomatic patients with SSc to detect abnormal increases in pulmonary pressures during exercise, but the pathophysiologic and prognostic significance of exercise stress echocardiography to assess the presence of HFpEF in these patients is unclear.
Methods And Results: Patients with SSc (n=140) underwent ergometry exercise stress echocardiography with simultaneous expired gas analysis.
Variants and vaccines impact nasal immunity over three waves of SARS-CoV-2.

Viral variant and host vaccination status impact infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), yet how these factors shift cellular responses in the human nasal mucosa remains uncharacterized. We performed single-cell RNA sequencing (scRNA-seq) on nasopharyngeal swabs from vaccinated and unvaccinated adults with acute Delta and Omicron SARS-CoV-2 infections and integrated with data from acute infections with ancestral SARS-CoV-2. Patients with Delta and Omicron exhibited greater similarity in nasal cell composition driven by myeloid, T cell and SARS-CoV-2 cell subsets, which was distinct from that of ancestral cases.
