Rheumatoid arthritis-associated antibodies in healthy first-degree relatives of RA patients.

Rheumatoid arthritis (RA) affects approximately 1.5% of the population worldwide and 0.5-3.

Anti-carbamylated protein antibodies positivity and disease activity in Hispanic patients with established rheumatoid arthritis: An observational study.

Objectives: We aimed to determine the prevalence of anti-carbamylated protein (anti-CarP) antibodies in Mexican Hispanics with established rheumatoid arthritis (RA) and to assess their relationship with disease activity.

Methods: A cohort study was conducted in 278 patients with established RA during an 18-month follow-up. We measured IgG/IgM/IgA rheumatoid factor (RF), IgG anticitrullinated protein antibodies (ACPA) and IgG/IgM/IgA anti-CarP antibodies using enzyme-linked immunosorbent assay (ELISA).

Low-dose rituximab therapy in steroid-refractory thrombocytopenia due to systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease, characterized by multi-organ symptomatology. 16% of the patients with autoimmune thrombocytopenia have SLE and are associated with high mortality. Intravenous methylprednisolone or high-dose steroids are the first-line treatments in those patients who experienced life-threatening bleeding or have a severely low platelet count, whereas a second line includes splenectomy, as well as other immunosuppressive agents as monotherapy or combined therapy, including azathioprine, cyclophosphamide, cyclosporine, and mycophenolate mofetil.

Perception of the risk of adverse reactions to analgesics: differences between medical students and residents.

Background. Medications are not exempt from adverse drug reactions (ADR) and how the physician perceives the risk of prescription drugs could influence their availability to report ADR and their prescription behavior. Methods.
