Comparison of the efficacy and safety of a proposed biosimilar MSB11456 with tocilizumab reference product in subjects with moderate-to-severe rheumatoid arthritis: results of a randomised double-blind study.

Objective: To evaluate the efficacy, immunogenicity and safety of the proposed biosimilar MSB11456 versus European Union (EU)-approved tocilizumab reference product in patients with rheumatoid arthritis (RA) in a multicentre, randomised, double-blind, multinational, parallel-group study (NCT04512001).

Methods: Adult patients with moderate-to-severe active RA and inadequate clinical response to ≥1 disease-modifying antirheumatic drug (synthetic or biologic) receiving methotrexate were randomised to receive 24 weekly subcutaneous 162 mg injections of either MSB11456 or EU-approved tocilizumab. Equivalence between treatments was considered if the 95% CI (European Medicines Agency)/90% CI (US Food and Drug Administration) for the difference in mean change from baseline to week 24 in Disease Activity Score-28 Joint Count with erythrocyte sedimentation rate (DAS28-ESR) between treatments was entirely within prespecified equivalence intervals (-0.

Blood serum levels of amino-terminal pro-C-type natriuretic peptide in patients with systemic sclerosis.

The aim of this pilot study was to examine the association of serum levels of amino-terminal fragment of pro-C-type natriuretic peptide (NT-proCNP), as a substitute measure of serum C-type natriuretic peptide (CNP), with clinical and laboratory findings in patients with systemic sclerosis (SSc). Serum NT-proCNP, soluble (s)E-and sP-selectin levels were examined using specific enzyme-linked immunosorbent assay in 30 patients with SSc and 30 healthy controls. We found no statistically significant difference in serum levels of NT-proCNP neither between patients with SSc and healthy controls nor between those treated with immunosuppressive agents and untreated patients.

Fucosylation of serum alpha1-acid glycoprotein in rheumatoid arthritis patients treated with infliximab.

To analyze fucosylation of alpha(1)-acid glycoprotein (AGP) and to identify relations between AGP fucosylation and clinical and biochemical indices of disease activity in patients with rheumatoid arthritis (RA) treated with monoclonal antitumor necrosis factor (TNF) antibody infliximab, we examined 22 patients with RA who underwent a 54-week treatment with infliximab according to ATTRACT protocol. Blood samples were collected at baseline and before every infusion of infliximab. AGP fucosylation was measured using lectin-binding enzyme-linked immunosorbent assay utilizing fucose-specific lectin Aleuria aurantia (AAL).

[Anticardiolipin antibodies and cardiac involvement in systemic lupus erythematosus].

Unlabelled: Anticardiolipin antibodies (aCL) are present in 24-61% of patients (pts) with systemic lupus erythematosus (SLE). It is suggested that they may be associated with valvular abnormalities recognized on echocardiography (ECHO). To evaluate the relation of raised aCL and cardiac abnormalities we performed ECHO in 48 pts with SLE.
