arthrtitis

BACKGROUND: Despite highly effective targeted therapies for rheumatoid arthritis, about 40% of patients respond poorly, and predictive biomarkers for treatment choices are lacking. We did a biopsy-driven trial to compare the response to rituximab, etanercept, and tocilizumab in biologic-naive patients with rheumatoid arthritis stratified for synovial B cell status. METHODS: STRAP and STRAP-EU were two parallel, open-label, biopsy-driven, stratified, randomised, phase 3 trials done across 26 university centres in the UK and Europe...

Tenosynovial giant cell tumor (TGCT) is a rare, benign, locally aggressive synovial based neoplastic process that can result in functional debilitation and end-stage arthrtitis. Although surgical resection is the primary treatment modality, novel systemic therapies are emerging as part of the multimodal armamentarium for patients with unresectable or complex disease burden. This review discusses the pathogenesis of TGCT, potential druggable targets and therapeutic approaches. It also evaluates the safety and efficacy of different systemic therapies...

BACKGROUND: Rheumatic diseases are increasingly present in the world population, represented by chronic joint and musculoskeletal pain. Among them, osteoarthritis (OA) is the most prevalent. It is considered the third most prevalent chronic non-communicable disease in the Brazilian population, being responsible for a high rate of physical disability and reduced quality of life. Little has been discussed about the social factors associated with this health condition. This study aimed to analyze the social factors associated with arthritis in the Brazilian population...

IL-1 family members include inflammatory and anti-inflammatory cytokines. They can be beneficial or detrimental, not only in cancer, but also in inflammatory conditions. Mast cells (MCs) originate from CD34+/CD117+/CD13+ pluripotent hematopoietic stem cells, express c-Kit receptor (c-Kit-R), which regulates the proliferation and sustain the survival, differentiation and maturation of MCs. They are immune cells involved in innate and adaptive immunity, allergy, autoimmunity, cancer and inflammation. MCs along with T cells and macrophages release interleukin (IL)-10, which is a pleiotropic immunoregulatory cytokine with multiple biological effects...

BACKGROUND: The G-DRG system reimburses sledge endoprosthetic implantations (UKA) at a much lower rate than surface replacements (TKA), at significantly different cost weights (CW). Therefore, when only G-DRG payments are considered, the complete endoprosthesis implantation produces higher gains. An orientation on these revenues alone, however, does not provide the basis for an economically sound decision-making process. The aim of this study is to present a comparison of the variable costs of the two procedures...

INTRODUCTION: Non-steroidal anti-inflammatory drugs and corticosteroids are both used in the treatment acute gouty arthritis and may adversely interact with colchicine. Gastrointestinal toxicity of colchicine is dose-dependent and can be aggravated by drug-drug and drug-patient interactions. CASE PRESENTATION: Colonic perforation associated with second-line administration of colchicine for acute gouty arthrtitis was identified in an elderly man with several comorbidities who was also treated with non-steroidal anti-inflammatory drugs and corticostroids...

OBJECTIVE: To evaluate the prevalence of thyroid disorders in a group of patients with psoriatic arthritis (PsA). METHODS: A complete thyroid investigation was carried out in 80 patients with PsA, in gender- and age-matched subjects (1:5) drawn from the general population (controls), and in 112 patients with rheumatoid arthrtitis (RA) with similar iodine intake. RESULTS: Anti-thyroid peroxidase antibodies (AbTPO), a hypoechoic thyroid, and subclinical hypothyroidism were significantly more frequent in women with PsA than in control women, and their frequency was similar to that in patients with RA (positive AbTPO titer 28%, 12%, and 31%; hypoechoic thyroid 31%, 16%, and 36%; subclinical hypothyroidism 25%, 8%, and 12%, respectively)...

OBJECTIVE: To study the circulating levels of interleukin-18 (IL-18), a proinflammtory cytokine implicated in the T helper I response, in patients with rheumatoid arthrtitis (RA) with or without amyloidosis. METHODS: Plasma IL-18 levels were studied by enzyme-linked immusorbent assay in 55 RA patients with reactive amyloidosis and in 55 RA patients without amyloidosis matched with respect to age, sex, seropositivity, disease duration and inflammatory activity, as well as in 55 healthy control subjects...
