Thrombotic events are a rare complication of recombinant activated factor VII (rFVIIa) therapy in patients with hemophilia. We present a case of a 71-year-old male who developed ST-elevation myocardial infarction after receiving rFVIIa replacement therapy for acquired hemophilia A.
RESUMEN
Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening inflammatory syndrome of severe immune system activation. It is a diagnostic challenge with high morbidity and mortality. We present a case of HLH due to anaplasmosis infection. A 54-year-old man with chronic obstructive pulmonary disease presented with fever, nausea, vomiting, dyspnea, and arthralgias for 6 days. He had a rapidly progressive clinical decline requiring intubation for acute respiratory failure and dialysis for acute renal failure. He tested positive for anaplasmosis. His workup met criteria for HLH. He was treated with doxycycline and a steroid taper with clinical improvement allowing for extubation and renal recovery. Patients with persistent fevers, hepatosplenomegaly, cytopenias, and hyperferritinemia should be worked up for HLH.
RESUMEN
The coronavirus disease 2019 (COVID-19) pandemic has resulted in millions of deaths worldwide. The emergency use authorization for both the Pfizer-BioNTech and Moderna mRNA COVID-19 vaccinations was a major turning point in the battle against COVID-19. These vaccines have been well-tolerated; however, there have been reported cases of myocarditis and pericarditis after receiving the second dose of the vaccine. We present two cases of myocarditis and pericarditis that occurred after receiving the COVID-19 vaccination. Although there are other potential etiologies that could explain myocarditis and pericarditis in these cases, it is important to consider the COVID-19 vaccine as a plausible cause. More research is required to investigate the potential adverse effects of the available COVID-19 vaccines.
