RESUMEN
PURPOSE OF REVIEW: This review focuses on the association between RA and heart failure, highlighting the role of inflammation and the prevalence of heart failure with preserved ejection fraction (HFpEF) in this population. RECENT FINDINGS: The incidence of heart failure in RA patients is two to three times higher than in the general population, with inflammation playing a significant role independent of traditional cardiovascular risk factors. HFpEF accounts for about half of heart failure cases and is increasingly recognized in RA patients, although it remains underdiagnosed. Atypical presentations and non-specific symptoms further complicate diagnosis. Early control of inflammation has been shown to reduce the risk of heart failure development and progression, improving both morbidity and mortality outcomes. Rheumatoid arthritis (RA) is a systemic inflammatory disease affecting approximately 1% of the population, with cardiovascular disease being the leading cause of premature death in these patients.

SARS-CoV-2 infection is causing a pandemic disease that is reflected in challenging public health problems worldwide. Human leukocyte antigen (HLA)-based epitope prediction and its association with disease outcomes provide an important base for treatment design. A bioinformatic prediction of T cell epitopes and their restricted HLA Class I and II alleles was performed to obtain immunogenic epitopes and HLA alleles from the spike protein of the severe acute respiratory syndrome coronavirus 2 virus. Also, a correlation with the predicted fatality rate of hospitalized patients in 28 states of Mexico was done. Here, we describe a set of 10 highly immunogenic epitopes, together with different HLA alleles that can efficiently present these epitopes to T cells. Most of these epitopes are located within the S1 subunit of the spike protein, suggesting that this area is highly immunogenic. A statistical negative correlation was found between the frequency of HLA-DRB1*01 and the fatality rate in hospitalized patients in Mexico.
