Differences in Clinical Profiles and Biologic Treatment Approaches for Autoimmune Rheumatic Diseases Across Regions in Mexico: An Analysis of the BIOBADAMEX Cohort.

Objective: Being Mexico a very diverse developing country, the access to health care varies among geographical regions. We aimed to assess the differences in clinical features and treatment prescription in 3 regions of Mexico using data from the Mexican Adverse Events Registry (BIOBADAMEX).

Methods: We included all BIOBADAMEX patients from 2016 to 2023, compared the prescription patterns, the sociodemographic, clinical, and treatment characteristics between the northern (NR), central (CR), and southern regions (SR), and addressed the treatment survival by calculating hazards ratios (HRs).

Right Ventricle and Autoimmune Diseases.

Autoimmune diseases can express pathologies in specific organs (e.g. thyroid, pancreas, skin) or generate systemic pathologies (generalized lupus erythematosus, rheumatoid arthritis, systemic sclerosis), the latter usually present systemic inflammatory phenomena.

Aspartic acid in the HLA-DRB1 chain and shared epitope alleles partially explain the high prevalence of autoimmunity in Mexicans.

Introduction: Autoimmune thyroid disease (AITD) is the most common autoimmune disorder worldwide. Remarkably, it is commonly accompanied by other autoimmune diseases, such as rheumatoid arthritis (RA). The immunopathogenic mechanisms behind the coexistence of these disorders are still not completely understood.

Mononeuritis Multiplex Associated With Antiphospholipid Antibodies.

In this article, we report the case of a 43-year-old male patient with mononeuritis multiplex associated with antiphospholipid antibodies. The patient had no other clinical or laboratory features of other systemic or autoimmune diseases or systemic vasculitis. He was treated with oral anticoagulant and mycophenolate mofetil, and is progressing favorably.
