To retrospectively evaluate the efficacy and safety of rituximab (Rtx) treatment in patients with anti-synthetase syndrome (ASS) and severe interstitial lung disease (ILD). ⋯ This study, which included 24 Rtx-treated ASS patients with severe ILD, reports improved PFTs after a median 52 months follow-up post-Rtx. The best outcome was observed in patients with a disease duration <12 months and/or acute onset/exacerbation of ILD. The study indicates that Rtx could be a treatment option for selected ASS patients, but infections should be given attention.

Multicenter Study
Responsiveness of the 36-item Short Form Health Survey and the Lupus Quality of Life questionnaire in SLE.
This study aimed to estimate the responsiveness to change of a generic [the 36-item Short Form Health Survey (SF-36)] and a specific health-related quality of life questionnaire [the Lupus Quality if Life questionnaire (LupusQoL)] according to SLE patients' self-reported changes in health status. ⋯ Both the SF-36 and LupusQoL were responsive to changes in QoL in SLE patients over a 3 month interval. LupusQoL seems to be more appropriate to measure improvements in QoL.

Observational Study
Assessment of myocardial fibrosis and microvascular damage in systemic sclerosis by magnetic resonance imaging and coronary angiotomography.
Cardiac involvement in SSc is characterized by myocardial fibrosis, arrhythmias and pericarditis. Prevalence studies have shown variable results. The objective of this study was to determine the prevalence of cardiac involvement in SSc patients using the non-invasive, highly sensitive diagnostic methods of cardiac MRI and coronary angiotomography. ⋯ The prevalence of myocardial fibrosis on MRI attributable to SSc is 45%, is more frequent and severe in dcSSc patients, is associated with lower LVEF and affects mainly basal LV walls. Microvascular damage in SSc is common and is associated with elevated ultrasensitive CRP levels. Cardiac damage due to SSc is not associated with coronary artery disease.
