Insights
COVID-19 can cause severe thrombotic events, including stroke and limb clots. This case highlights a rare association with cold agglutinin autoimmune hemolytic anemia, emphasizing the need for prompt diagnosis and management in patients with COVID-19 and thrombosis.
Area of Science:
- Internal Medicine
- Hematology
- Infectious Diseases
Background:
- COVID-19 is a global pandemic characterized by respiratory symptoms and a significant inflammatory response.
- A hypercoagulable state is frequently observed in COVID-19 patients, leading to thrombotic complications.
- The interplay between COVID-19, thrombosis, and autoimmune conditions requires further investigation.
Observation:
- A patient presented with symptoms of cerebrovascular accident and confirmed blood clots in both upper extremities.
- Laboratory tests revealed the presence of cold agglutinin autoimmune hemolytic anemia (AIHA).
- The patient's condition rapidly deteriorated, resulting in death within 48 hours of admission.
Findings:
- This case describes a rare occurrence of cold agglutinin AIHA in a patient with COVID-19.
- The association between COVID-19, AIHA, and severe thrombotic events is not well-established.
- The patient experienced multiple thrombotic events, including stroke and peripheral clots.
Implications:
- This case underscores the importance of considering AIHA in the differential diagnosis of thrombotic events in COVID-19 patients.
- Early diagnosis and appropriate management of AIHA may be crucial for improving outcomes in these patients.
- Further research is needed to elucidate the mechanisms linking COVID-19, AIHA, and thrombosis and to guide therapeutic strategies.
Abstract:
Novel coronavirus disease 2019 (COVID-19) has spread throughout the world and has infected close to 4 million people. It commonly presents with fever, cough, and fatigue. Due to the high inflammatory response, it is suggested that the coagulation cascade is enhanced causing thrombotic events for many patients. We describe a patient with clinical features of cerebrovascular accident, as well as documented blood clots in bilateral upper extremities. Labs revealed the presence of cold agglutinin hemolytic anemia. The association between cold agglutinin autoimmune hemolytic anemia and thrombotic events in COVID-19 patients has not been well investigated. The patient unfortunately passed away within 48 hours after admission. This case stresses the importance of considering a full workup to diagnose autoimmune hemolytic anemia (AIHA) in COVID-19 patients with thromboses and possible implications for management.

The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
