Humoral Response of Patients With Autoimmune Rheumatic Disease to BNT162b2 Vaccine: A Retrospective Comparative Study.

Objective The effectiveness and safety of SARS-CoV-2 vaccines in patients with autoimmune rheumatic diseases (ARDs) treated with immunomodulators remain uncertain. Therefore, this study aimed to evaluate whether the humoral immune response to the BNT162b2 vaccine differs between patients without and with ARDs treated with immunomodulators. Methods We retrospectively reviewed 3208 electronic medical records from the database of the Hamad Medical Corporation (HMC) outpatient rheumatology clinics to capture patients with ARDs and control patients without autoimmune inflammatory diseases.

Cardiac Tamponade: An Unusual Cause of a Severe Headache with Normal Blood Pressure.

Cardiac tamponade is a life-threatening condition characterized by slow or rapid compression of the heart due to the accumulation of fluid in the pericardial space and rarely presents mainly as a headache. We report an unusual presentation of cardiac tamponade associated mainly with severe headache over three days and mild shortness of breath in a 60-year-old male not known to have any previous heart disease. Immediate computed tomography (CT) scan of the head ruled out intracranial hemorrhage.
