A Rare Case of Cold Agglutinin Syndrome Associated With Legionella Pneumonia.

Cold agglutinin syndrome (CAS) is a rare subset of autoimmune hemolytic anemia (AIHA) and can be classified as either primary or secondary. Secondary cold agglutinin disease has been associated with both viral and bacterial pathogens with the most common bacterial pathogen being . pneumonia is a well-known causative agent for community-acquired pneumonia that can lead to a severe disease requiring hospitalization that is rarely associated with AIHA.

Anticoagulation With Platelet Transfusions for Acute Limb Ischemia With Severe Thrombocytopenia.

Acute limb ischemia (ALI) is a medical and surgical emergency, and the mainstays of treatment are therapeutic anticoagulation and surgery. These interventions require adequate platelet count and functionality. Anticoagulation and surgery can be complicated in thrombocytopenic patients and require interdisciplinary management for optimal outcomes, as literature is limited in this population.

Urgent Revascularization of the Left Proximal Circumflex Following Cessation of Cangrelor Within Six Hours of Procedure.

Patients undergoing procedures are often transitioned off anticoagulants using anti-platelet agents with short half-lives as a "bridge." We present the case of a patient with a history of in-stent thromboses who experienced a thrombotic event following a literature-guided bridging protocol. This case is one of the first to show that stopping cangrelor within six hours led to a need for urgent revascularization and suggests that the timing for discontinuing bridging agents should be customized based on the patient's history of increased blood clotting.
