Hemolytic Anemia as a Provoking Factor for Recurrent Venous Thromboembolism: A Case Report.

Warm antibody autoimmune hemolytic anemia (WAIHA) is a rare disease that leads to the destruction of red blood cells in the reticuloendothelial system through the mediation of agglutinins (immunoglobulin G (IgG) type in most cases) that attach to the erythrocyte wall at 37 °C. The association of WAIHA and venous thromboembolism (VTE) seems to be higher than other hemolytic disorders classically associated with VTE and there is a current investigation aimed at clarifying this association and establishing some criteria to use anticoagulant treatment in patients with WAIHA. Despite this, WAIHA is a rare cause for the development of recurrent VTE under secondary prophylactic anticoagulant treatment, with only a few cases described in the literature.

A retrospective analysis of incidence and severity of COVID-19 among hypertensive patients: the other side.

Objective: The role of hypertension in COVID-19 has not been clearly elucidated yet. The aim of this study was to evaluate the incidence and severity of COVID-19 in a hypertensive population and assess whether there is a link between blood pressure control and SARS-CoV-2 infection outcomes.

Methods: This was a single-center retrospective observational study that evaluated the incidence and severity of COVID-19 in a chronic hypertensive population (n=1,637) from a specialized consultation of Hypertension and Cardiovascular Risk of Internal Medicine in a tertiary hospital in Madrid (Spain).
