Dual targeted therapy in patients with psoriatic arthritis and spondyloarthritis: a real-world multicenter experience from Spain.

Dual targeted therapy (DTT) has emerged as a promising approach in patients with refractory spondyloarthritis (SpA) or psoriatic arthritis (PsA) and extra-musculoskeletal manifestations of both diseases, but its effectiveness/safety ratio still remains unclear. This is a retrospective, real-world multicenter study in refractory SpA and PsA patients with simultaneous use of two biological or synthetic targeted agents. Effectiveness was assessed using Ankylosing Spondylitis Disease Activity Score with C-reactive protein (ASDAS-CRP) and Disease Activity in Psoriatic Arthritis (DAPSA) Score.

Ultrasonography in the diagnosis of suspected primary Sjögren's syndrome and concordance with salivary gland biopsy: a Spanish single-center study.

Objective: The study aims to evaluate the utility of major salivary gland ultrasonography for diagnosis of primary Sjögren's syndrome (pSS) and to assess its concordance with minor salivary gland biopsy (MSGB).

Methods: A cross-sectional study of 72 patients with suspected pSS was performed. Demographic, clinical, and serological data were collected.

A treat-to-target approach for gout confers renoprotective effect in patients with chronic kidney disease stage 3.

The aim of this study was to assess changes in the estimated glomerular filtration rate (eGFR) in gouty patients with chronic kidney disease (CKD) using a "treat-to-target" (T2T) approach in gout. This multicenter observational retrospective study included patients diagnosed with gout and CKD stage 3 taking xanthine oxidase inhibitors (XOIs) (allopurinol or febuxostat) for at least 12 months. All patients were treated using a T2T strategy according to national gout guidelines to achieve the target levels of serum uric acid (sUA; < 5-6 mg/dl) within 6 months of the first visit.

Impact of genetic variants of ATP binding cassette B1, AICAR transformylase/IMP cyclohydrolase, folyl-polyglutamatesynthetase, and methylenetetrahydrofolatereductase on methotrexate toxicity.

Objective: To analyze the effect of single nucleotide polymorphisms (SNPs) with well-known functional impact of methylenetetrahydrofolatereductase (MTHFR; rs1801131 and rs1801133), the membrane transporter ABCB1 (rs1045642), the AICAR transformylase/IMP cyclohydrolase (ATIC; rs2372536) and folyl-polyglutamatesynthetase (FPGS; rs1544105), on liver and bone marrow toxicity of methotrexate (MTX).

Patients And Methods: We analyzed 1415 visits from 350 patients of the PEARL (Princesa Early Arthritis Register Longitudinal) study: (732 with MTX, 683 without MTX). The different SNPs were genotyped using specific TaqMan probes (Applied Biosystems).

HLA-DRB1 association with Henoch-Schonlein purpura.

Objective: Henoch-Schönlein purpura (HSP) is the most common vasculitis in children but it is not exceptional in adults. Increased familial occurrence supports a genetic predisposition for HSP. In this context, an association with the human leukocyte antigen-HLA-DRB1*01 phenotype has been suggested in Caucasian individuals with HSP.
