In a cohort of patients with SLE originating from Israel and Europe vitamin D serum concentrations were found to be inversely related to disease activity.

The Central European Congress of Rheumatology (CECR) has been organized by seven Central European countries: Austria, Croatia, Czech Republic, Hungary, Poland, Slovakia, and Slovenia. These countries have lots of similarities, but also differences, with respect to rheumatology research. In this paper, based on questionnaires, we wish to demonstrate achievements and difficulties in rheumatology research performed in our region.

AimThe objective was to examine the prevalence of atherosclerotic cardiovascular disease (ASCVD) and its risk factors among patients with RA with diabetes mellitus (RA-DM) and patients with RA without diabetes mellitus (RAwoDM), and to evaluate lipid and blood pressure (BP) goal attainment in RA-DM and RAwoDM in primary and secondary prevention.MethodsThe cohort was derived from the Survey of Cardiovascular Disease Risk Factors in Patients with Rheumatoid Arthritis from 53 centres/19 countries/3 continents during 2014–2019. We evaluated the prevalence of cardiovascular disease (CVD) among RA-DM and RAwoDM. The study population was divided into those with and without ASCVD, and within these groups we compared risk factors and CVD preventive treatment between RA-DM and RAwoDM.ResultsThe study population comprised of 10 543 patients with RA, of whom 1381 (13%) had DM. ASCVD was present in 26.7% in RA-DM compared with 11.6% RAwoDM (p<0.001). The proportion of patients with a diagnosis of hypertension, hyperlipidaemia and use of lipid-lowering or antihypertensive agents was higher among RA-DM than RAwoDM (p<0.001 for all). The majority of patients with ASCVD did not reach the lipid goal of low-density lipoprotein cholesterol <1.8 mmol/L. The lipid goal attainment was statistically and clinically significantly higher in RA-DM compared with RAwoDM both for patients with and without ASCVD. The systolic BP target of <140 mm Hg was reached by the majority of patients, and there were no statistically nor clinically significant differences in attainment of BP targets between RA-DM and RAwoDM.ConclusionCVD preventive medication use and prevalence of ASCVD were higher in RA-DM than in RAwoDM, and lipid goals were also more frequently obtained in RA-DM. Lessons may be learnt from CVD prevention programmes in DM to clinically benefit patients with RA .

Antibodies (Abs) against the structure specific recognition protein 1 (SSRP1) were reported in a small systemic lupus erythematosus (SLE) series but not in other systemic autoimmune diseases. The aim of the study was to confirm the selective presence of anti-SSRP1 Abs in a larger SLE series and to evaluate their relationship with disease activity and other immune markers. Anti-SSRP1 Abs were investigated by a 'home made' ELISA in: 120 SLE, 65 rheumatoid arthritis (RA), 51 systemic sclerosis (SSc), 23 Churg-Strauss syndrome (CSS) and 40 idiopathic autoimmune urticaria (IAU) patients and 190 healthy controls. Sera from MRL lpr/lpr and Balb-c mice were also tested. Anti-SSRP1 Abs were detected in 43 SLE (35.8%), nine SSc (17.6%), eight RA (12.3%), six IAU (15%), three CSS (13%) patients and five healthy controls (2.6%). Antibody prevalence and titers were significantly higher in SLE patients than in sera from both normal and disease controls. Anti-SSRP1 Ab activity was also detected in sera from MRL lpr/lpr but not Balb-c mice. The antibodies did not correlate with the disease activity evaluated as the ECLAM index score and were more prevalent in patients without renal involvement. No correlation was found with other serum autoantibodies. Our results confirm that anti-SSRP1 Abs are associated with but not specific for the lupus disease.
