Real-world psychosocial impact among patients with juvenile idiopathic arthritis and families in Spain.

Background: To assess the psychosocial impact of moderate-severe juvenile idiopathic arthritis (JIA) on patients and their families, among those who had been treated with at least one anti-tumor necrosis factor (anti-TNF-α), according to routine clinical practice in Spain.

Patients And Methods: A 24-month observational, multicentric, cross-sectional and retrospective study was performed. Children diagnosed with JIA were enrolled at three tertiary-care Spanish hospitals.

Juvenile idiopathic arthritis in the young adult. Methodology, objectives, and initial data from the JUVENSER registry.

Objectives: To describe the methodology, objectives, and initial data of the registry of young adult patients diagnosed with Juvenile Idiopathic Arthritis (JIA), JUVENSER. The main objective of the project is to know the sociodemographic and clinical characteristics, and disease activity of patients with JIA reaching the transition to adulthood.

Material And Method: Longitudinal, prospective, multicentre study, including patients between 16 and 25 years old, with a diagnosis of JIA in any of its categories.

Ultrasound in pediatric rheumatology: Highlighting the differences with adults.

Musculoskeletal ultrasound (MSUS) is a powerful tool of major importance in rheumatology. MSUS is ideally suited for the evaluation of pediatric patients because it is a safe technique with a high patient acceptability, it does not require sedation, and it is excellent for exploring multiple joints. It is also the most operator-dependent imaging modality, and assessing joints in patients with juvenile idiopathic arthritis (JIA) is particularly challenging due to the unique features of the growing skeleton.

Effectiveness and safety of bisphosphonates therapy in secondary osteoporosis in children.

Introduction: There are few studies on effectiveness and safety of bisphosphonate therapy in secondary osteoporosis in children. The aim of this research was to analyse effectiveness and safety of bisphosphonates in secondary osteoporosis in children.

Patients And Methods: Multicentre retrospective study in patients younger than 18 suffering from secondary osteoporosis and who have received bisphosphonates.

A young girl with severe polyarteritis nodosa successfully treated with tocilizumab: a case report.

Background: Childhood Polyarteritis nodosa (PAN) is a systemic vasculitis with necrotizing inflammation of medium- and small-sized arteries. Disease evolution may be severe and refractory to standard treatment including prednisone, azathioprine and cyclophosphamide.

Case Presentation: We present the case of a young girl with severe PAN resulting in progressive ischemia and necrosis of fingers and toes.

Targeting of the CD80/86 proinflammatory axis as a therapeutic strategy to prevent severe COVID-19.

An excessive immune response known as cytokine storm is the hallmark of severe COVID-19. The cause of this cytokine rampage is yet not known. Based on recent epidemiological evidence, we hypothesized that CD80/86 signaling is essential for this hyperinflammation, and that blocking this proinflammatory axis could be an effective therapeutic approach to protect against severe COVID-19.

Overview of STING-Associated Vasculopathy with Onset in Infancy (SAVI) Among 21 Patients.

Background: Gain-of-function mutations in STING1 underlie a type I interferonopathy termed SAVI (STING-associated vasculopathy with onset in infancy). This severe disease is variably characterized by early-onset systemic inflammation, skin vasculopathy, and interstitial lung disease (ILD).

Objective: To describe a cohort of patients with SAVI.

Abatacept in interstitial lung disease associated with rheumatoid arthritis: national multicenter study of 263 patients.

Objective: To assess the efficacy of abatacept (ABA) in RA patients with interstitial lung disease (ILD) (RA-ILD).

Methods: This was an observational, multicentre study of RA-ILD patients treated with at least one dose of ABA. ILD was diagnosed by high-resolution CT (HRCT).

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.

Expert panel consensus recommendations for diagnosis and treatment of secondary osteoporosis in children.

Background: Osteoporosis incidence in children is increasing due to the increased survival rate of patients suffering from chronic diseases and the increased use of drugs that can damage bones. Recent changes made to the definition of childhood osteoporosis, along with the lack of guidelines or national consensuses regarding its diagnosis and treatment, have resulted in a wide variability in the approaches used to treat this disease. For these reasons, the Osteogenesis Imperfecta and Childhood Osteoporosis Working Group of the Spanish Society of Pediatric Rheumatology has sounded the need for developing guidelines to standardize clinical practice with regard to this pathology.

A Combined Transcriptomic and Genomic Analysis Identifies a Gene Signature Associated With the Response to Anti-TNF Therapy in Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is the most frequent autoimmune disease involving the joints. Although anti-TNF therapies have proven effective in the management of RA, approximately one third of patients do not show a significant clinical response. The objective of this study was to identify new genetic variation associated with the clinical response to anti-TNF therapy in RA.

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.

Genome-wide association study meta-analysis identifies five new loci for systemic lupus erythematosus.

Background: Systemic lupus erythematosus (SLE) is a common systemic autoimmune disease with a complex genetic inheritance. Genome-wide association studies (GWAS) have significantly increased the number of significant loci associated with SLE risk. To date, however, established loci account for less than 30% of the disease heritability and additional risk variants have yet to be identified.

Abatacept in patients with rheumatoid arthritis and interstitial lung disease: A national multicenter study of 63 patients.

Objective: Interstitial lung disease (ILD) is one of the most serious complications of rheumatoid arthritis (RA). In the present study, we aimed to assess the efficacy of abatacept (ABA) in patients with ILD associated to RA.

Methods: National multicenter, non-controlled, open-label registry study of RA patients with ILD treated with ABA.

Genome-wide pathway analysis identifies VEGF pathway association with oral ulceration in systemic lupus erythematosus.

Background: Systemic lupus erythematosus (SLE) is a genetically complex rheumatic disease characterized by heterogeneous clinical manifestations of unknown etiology. Recent studies have suggested the existence of a genetic basis for SLE heterogeneity. The objective of the present study was to identify new genetic variation associated with the clinically relevant phenotypes in SLE.
