Objective: The aim of this study was to evaluate the influence of anti-infliximab (IFX) antibodies on three different points of care: response/tolerance to IFX, tapering strategy, and in a subsequent treatment with a second tumor necrosis factor inhibitor (TNFi).
Methods: A prospective cohort of 60 patients with radiographic axial spondyloarthritis who received IFX were evaluated retrospectively regarding clinical/laboratorial data, IFX levels, and anti-IFX antibodies at baseline, after 6, 12 to 14, 22 to 24, 48 to 54, 96 to 102 weeks, and before tapering or switching.
Results: Anti-IFX antibodies were detected in 27 patients (45%), of whom 23 (85.
Objectives: To evaluate humoral responses to three doses of the inactivated SARS-CoV-2 vaccine (CoronaVac) in patients with spondyloarthritis (SpA) and the effect of therapy, compared with a control group (CG).
Methods: Prospective cohort of axial SpA/psoriatic arthritis patients and age/sex-balanced CG from the CoronavRheum phase 4 trial (NCT04754698). CoronaVac was given in two doses (28-days interval) with a booster at day 210.
Psoriatic arthritis (PsA) is a chronic and systemic immune disease characterized by inflammation of peripheral and/or axial joints and entheses in patients with psoriasis (PsO). Extra-articular and extracutaneous manifestations and numerous comorbidities can also be present. These recommendations replace the previous version published in May 2013.

Over some decades, nonsteroidal anti-inflammatory drugs (NSAIDs) have been the basis for the pharmacological treatment of patients with axial spondyloarthritis (axSpA). However, the emergence of the immunobiologic agents brought up the discussion about the role of NSAIDs in the management of these patients.

The classification axial spondyloarthritis is adopted when the spine and/or the sacroiliac joints are predominantly involved. This version of recommendations replaces the previous guidelines published in May 2013.

- The study aimed to assess the prevalence of dyslipoproteinemia (abnormal lipid levels) in a group of 28 patients with polyarticular juvenile idiopathic arthritis, excluding factors like diabetes and medication that could affect lipid levels.
- Results showed that 71% of the patients had dyslipoproteinemia, primarily characterized by low levels of high-density lipoprotein (HDL) cholesterol, with male patients showing significantly lower HDL than females.
- The findings suggest that dyslipoproteinemia is common among these patients regardless of disease activity or treatment, highlighting the need for early intervention to manage lipid levels effectively.
Collagen V shows promise as an inducer of the death response via caspases. Remodeling of the microenvironment by collagen V, tumoral/vascular apoptosis, and the immune response were evaluated, based on the prognosis of 65 patients with surgically excised non-small cell lung cancer. Immunofluorescence, immunohistochemistry, morphometry, tridimensional reconstruction, and a real-time polymerase chain reaction were used to evaluate the amount, structure, and molecular chains of collagen V, tumoral and vascular apoptosis, immune cells, and microvessel density.
