Objective: To update the consensus document of the Spanish Society of Rheumatology (SER) regarding the use of targeted biological and synthetic therapies in rheumatoid arthritis (RA) with the aim of assisting clinicians in their therapeutic decisions.

Methods: A panel of 13 experts was assembled through an open call by SER. We employed a mixed adaptation-elaboration-update methodology starting from the 2015 Consensus Document of the Spanish Society of Rheumatology on the use of biological therapies in RA.

Article Synopsis
  • The EXXELERATE study found that patients with rheumatoid arthritis (RA) and high rheumatoid factor (RF) levels (>203 IU/mL) had worse clinical outcomes when treated with adalimumab (ADL).
  • This new study aimed to investigate how RF levels affect the serum levels of TNF inhibitors and the risk of secondary nonresponse in RA patients.
  • Results showed that high RF levels were linked to lower drug levels and a significantly higher risk of treatment discontinuation in patients using infliximab (IFX) or ADL, but not in those treated with certolizumab pegol (CZP).

Introduction: The nature of the relationship between inflammation, cardiovascular (CV) risk factors and atherosclerosis in axial spondyloarthritis (axSpA) remains largely unknown and sex differences in this regard are yet to be assessed.

Methods: Study including 611 men and 302 women from the Spanish multicentre AtheSpAin cohort to assess CV disease in axSpA. Data on CV disease risk factors were collected both at disease diagnosis and at enrolment, and data on disease activity, functional indices and carotid ultrasonography only at enrolment.

Background: Rheumatic and musculoskeletal diseases (RMDs) are chronic diseases that may alternate between asymptomatic periods and flares. These conditions require complex treatments and close monitoring by rheumatologists to mitigate their effects and improve the patient's quality of life. Often, delays in outpatient consultations or the patient's difficulties in keeping appointments make such close follow-up challenging.

Background: The role of ustekinumab (UST) and vedolizumab (VDZ) in the extraintestinal joint manifestations of inflammatory bowel disease (IBD) remain unclear, and most existing studies are retrospective. The aim of this prospective study was to analyze the incidence of new-onset joint disease or the worsening of pre-existing IBD-associated joint disease in patients treated with UST and VDZ.

Methods: The study population comprised IBD patients with previous spondyloarthritis (SpA) or new-onset arthropathy undergoing treatment with VDZ or UST.

Objective: To assess whether the retention rate of certolizumab pegol (CZP) was longer than that of other tumour necrosis factor inhibitors (TNFi) based on baseline rheumatoid factor (RF) levels.

Methods: Longitudinal, retrospective and multicentre study including patients with RA who were treated with any TNFi (monoclonal antibodies (mAB), etanercept (ETA) or CZP). Log-rank test and Cox regressions were conducted to evaluate the retention rate in the three groups according to the level of RF, with the third quartile of the baseline levels used as cut-off: <200 ( View Article and Find Full Text PDF

Article Synopsis
  • Certolizumab pegol (CZP) maintains stable serum levels in rheumatoid arthritis (RA) patients, regardless of baseline rheumatoid factor (RF) status, while treatment with infliximab (IFX) and adalimumab (ADL) shows varying serum drug levels based on RF levels.
  • A study of 170 RA patients found that high baseline RF levels were associated with lower serum drug levels for IFX and ADL, but not CZP, after six months.
  • Patients with high RF levels experienced higher rates of treatment discontinuation due to non-response with IFX and ADL compared to those receiving CZP, highlighting potential treatment differences based on RF levels.

Article Synopsis
  • The study aimed to explore the formation of anti-drug antibodies (ADA) against infliximab (IFX) and how these relate to drug levels and patient outcomes in rheumatoid arthritis (RA) and spondyloarthritis (SpA).
  • Serum samples were collected from 106 patients over time, and two different assays were used to detect ADA and measure IFX levels, with the drug-tolerant assay identifying ADA earlier than the drug-sensitive assay.
  • Results showed that patients who developed ADA earlier had lower levels of IFX and shorter drug survival, suggesting early immunogenicity affects the treatment's effectiveness.

Introduction: Rheumatoid arthritis (RA) is a heterogeneous disease in which therapeutic strategies used have evolved dramatically. Despite significant progress in treatment strategies such as the development of anti-TNF drugs, it is still not possible to differentiate those patients who will respond from who will not. This can lead to effective-treatment delays and unnecessary costs.

The emergence of large language models (LLM) with remarkable performance such as ChatGPT and GPT-4, has led to an unprecedented uptake in the population. One of their most promising and studied applications concerns education due to their ability to understand and generate human-like text, creating a multitude of opportunities for enhancing educational practices and outcomes. The objective of this study is twofold: to assess the accuracy of ChatGPT/GPT-4 in answering rheumatology questions from the access exam to specialized medical training in Spain (MIR), and to evaluate the medical reasoning followed by these LLM to answer those questions.

Background: There is a lack of outcome measures for the assessment of physical activity in patients with axial spondyloarthritis (axSpA). For this matter, the modified Short QUestionnaire to Assess Health (mSQUASH) was developed and validated, originally in Dutch.

Objective: To translate and cross-culturally adapt the mSQUASH into Spanish and to evaluate the equivalence of the translated version in patients with axSpA.

The 2021 guidelines on the prevention of vascular disease (VD) in clinical practice published by the European Society of Cardiology (ESC) and supported by 13 other European scientific societies recognize the key role of screening for chronic kidney disease (CKD) in the prevention of VD. Vascular risk in CKD is categorized based on measurements of estimated glomerular filtration rate (eGFR) and urine albumin to creatinine ratio (ACR). Thus, moderate CKD is associated with a high vascular risk and severe CKD with a very high vascular risk requiring therapeutic action, and there is no need to apply other vascular risk scores when vascular risk is already very high due to CKD.

Mobile health technology holds great promise for the clinical management of patients with chronic disease. However, evidence on the implementation of projects involving digital health solutions in rheumatology is scarce. We aimed to study the feasibility of a hybrid (virtual and face-to-face) monitoring strategy for personalized care in rheumatoid arthritis (RA) and spondyloarthritis (SpA).

Background: Rheumatic and Musculoskeletal Diseases (RMDs) substantially impact the lives of patients, with complex associations between disease severity and self-perceived health status. In this regard, the Coping with Rheumatic Stressors (CORS) questionnaire was developed to measure how patients with RMDs cope with stressors such as pain, limitations or dependency. The CORS is not currently available in Spanish, and therefore the adaptation of this instrument is needed.

Article Synopsis
  • The study aimed to understand differences between patients with difficult-to-treat rheumatoid arthritis (D2TRA), focusing on those with treatment failures due to inefficacy versus other causes like adverse events or poor adherence.
  • A total of 253 patients were analyzed, revealing no significant demographic differences between D2TRA patients and those who were successfully treated; however, those in the D2TRA-other group had fewer extra-articular manifestations.
  • The findings suggest that patients categorized under D2TRA-other are similar to non-D2TRA patients at the beginning of treatment, indicating potential areas for better management and understanding of this condition.
