Multidisciplinary models for pregnancy care in patients with rheumatic diseases: Clinical experiences and experts opinion.

Objectives: To describe different models of multidisciplinary pregnancy care for patients with inflammatory and autoimmune rheumatic diseases, and the steps to follow concerning their implementation.

Methods: A qualitative study was conducted including: (1) a comprehensive literature search in PUBMED focused on multidisciplinary care models; (2) structured interviews with seven rheumatologists from multidisciplinary pregnancy clinics for patients with inflammatory and autoimmune rheumatic diseases. Data were collected related to the hospitals, medical departments, populations cared for, and multidisciplinary care models (type, material, and human resources, professional requirements, objectives, referral criteria, agendas, protocols, responsibilities, decision-making, research and educational activities, multidisciplinary clinical sessions, initiation/start, planning, advantages/disadvantages, and barriers/facilitators for implementation); (3) a nominal meeting group in which the results of searches and interviews were analyzed and the recommendations for the implementation of the multidisciplinary care models defined.

The ovarian reserve as measured by the anti-Müllerian hormone is not diminished in patients with rheumatoid arthritis compared to the healthy population.

Objectives: Rheumatoid arthritis (RA) is the most prevalent chronic inflammatory arthritis, affecting 0.5-1% worldwide population and predominates in females. Altered fertility has been reported due to a decrease in ovarian reserve secondary to sustained inflammation.

Incidence of COVID-19 in a cohort of adult and paediatric patients with rheumatic diseases treated with targeted biologic and synthetic disease-modifying anti-rheumatic drugs.

Objectives: To investigate the incidence of COVID-19 in a cohort of adult and paediatric patients with rheumatic diseases receiving targeted biologic and synthetic disease modifying anti-rheumatic drugs (tDMARDs) and to explore the possible effect of these treatments in the clinical expression of COVID-19.

Methods: A cross-sectional study comprising of a telephone survey and electronic health records review was performed including all adult and paediatric patients with rheumatic diseases treated with tDMARDs in a large rheumatology tertiary centre in Barcelona, Spain. Demographics, disease activity, COVID-19 related symptoms and contact history data were obtained from the start of the 2020 pandemic.

A questionnaire-based study on contraceptive practice in patients with rheumatic disease found no significant difference in age-matched healthy controls.

Objective: Birth control is crucial in preventing unplanned pregnancy. The study analyzed contraceptive practice in women and men with rheumatic disease.

Methods: A questionnaire-based study investigated the actual contraceptive practices in patients of reproductive age from three European countries and compared them to age-matched healthy women and men.

Genetic association between CD96 locus and immunogenicity to anti-TNF therapy in Crohn's disease.

The production of antibodies to anti-tumor necrosis factor alpha (TNF) agents is one of the main causes of treatment failure in Crohn's disease (CD). To date, however, the contribution of genetics to anti-TNF immunogenicity in CD is still unknown. The objective of the present study was to identify genetic variation associated with anti-TNF immunogenicity in CD.

Genetic variation at the glycosaminoglycan metabolism pathway contributes to the risk of psoriatic arthritis but not psoriasis.

Objective: Psoriatic arthritis (PsA) is a chronic inflammatory arthritis affecting up to 30% of patients with psoriasis (Ps). To date, most of the known risk loci for PsA are shared with Ps, and identifying disease-specific variation has proven very challenging. The objective of the present study was to identify genetic variation specific for PsA.

Epigenome-wide association study of rheumatoid arthritis identifies differentially methylated loci in B cells.

Epigenetic regulation of immune cell types could be critical for the development and maintenance of autoimmune diseases like rheumatoid arthritis (RA). B cells are highly relevant in RA, since patients express autoantibodies and depleting this cell type is a successful therapeutic approach. Epigenetic variation, such as DNA methylation, may mediate the pathogenic activity of B cells.
