Case history: A 55 year-old female presented to A&E with left iliac fossa pain and vomiting, 8 days following her first dose of the AstraZeneca COVID-19 vaccine. She had a background of hypothyroidism, hypertension and hysterectomy for menorrhagia at age 25 – no prior thrombotic history. She underwent emergency laparoscopy for suspected torsion, which was converted to laparotomy for ovarian necrosis secondary to left ovarian vein thrombosis. Post-operatively, isolated...

Background: Corticosteroid Binding Globulin (CBG) binds >85% of plasma cortisol and controls the circulating free cortisol pool. Proteolytic cleavage by neutrophil elastase is proposed to reduce CBG binding affinity and increase free cortisol availability to inflamed tissues. The CORtisol NETwork (CORNET) consortium found that genetic variation at a locus spanning SERPINA1 (encoding alpha-1 antitrypsin, A1AT, the endogenous inhibitor of neutrophil elastase) and SE...

Introduction: Corticosteroid Binding Globulin (CBG) binds >85% of plasma cortisol and modulates free cortisol levels. Observations in vitro show that CBG is cleaved by neutrophil elastase (NE), a mechanism proposed to reduce CBG binding affinity and increase free cortisol availability to inflamed tissues. However, detection of cleaved CBG in vivo in human plasma is controversial, and any influence of NE on CBG cleavage has not been tested in vivo...
