Abstract
Sickle cell trait (SCT) is the carrier state for sickle cell disease (SCD) and is usually perceived as a mild condition; however, previous studies have shown that hypoxemia may trigger sickle-cell related complications in these patients, including splenic infarction. Hypoxemia is a common finding in patients with COVID-19 pneumonia.We present the case of a 19-year-old male with a history of epilepsy who presented to the emergency room due to abdominal pain in the left flank that appeared after presenting generalized tonic-clonic seizures and fever. SARS-CoV-2 RT-PCR testing in nasopharyngeal swab was positive and an abdominal computerized tomography (CT) revealed a massive splenic infarction. Hemoglobinopathy study using high-efficiency liquid chromatography demonstrated the presence of 39.7% HbS, thus confirming the diagnosis of SCT.Hypoxemia, endothelial dysfunction and hypercoagulability caused by SARS-CoV-2 infection could lead to complement activation and microangiopathy, triggering the vaso-occlusive crisis that led to splenic infarction.
