The Successful Management of Stroke in Evans Syndrome by Anticoagulation with Warfarin, Intravenous Immunoglobulin (IVIG), and High-Dose Corticosteroid.

UNLABELLED

Evans syndrome (ES) is a rare autoimmune disorder characterised by autoimmune haemolytic anaemia (AIHA), immune thrombocytopenia and autoimmune neutropenia. The precise pathogenesis of ES remains unclear, but it is believed to involve immune-mediated destruction of erythrocytes and platelets. Thrombotic complications, such as stroke, are critical yet largely unrecognised in ES. Here, we present a case of an 80-year-old male with ES who developed multiple strokes, emphasising the complex management challenges associated with this condition. The patient, known for stage IIB lung adenocarcinoma, presented with right-sided weakness and was diagnosed with a stroke of undetermined aetiology. He was started on warfarin for secondary prevention alongside intravenous immunoglobulin (IVIG) and corticosteroids for ES. Stroke in ES is rarely reported, and the optimal management remains inconclusive due to its rarity. The patient's management was guided by existing guidelines for stroke prevention and anticoagulation in the setting of antiphospholipid syndrome. While anticoagulants are recommended for venous thromboembolism prophylaxis in AIHA, there are no clear guidelines for stroke prevention in ES. This case underscores the necessity of individualised treatment approaches and highlights the gaps in evidence regarding stroke management in ES. Future research is essential to determine the optimal management of stroke in this complex clinical scenario.

LEARNING POINTS

Evans syndrome is a rare autoimmune disorder characterised by the coexistence of autoimmune haemolytic anaemia and immune thrombocytopenia, which potentially increase venous and arterial thrombotic risk.Managing strokes in Evans syndrome remains challenging due to its rarity and lack of definitive guidelines, necessitating individualised treatment approaches.Future prospective studies are warranted to determine the optimal patient population that needs secondary prevention with anticoagulants following a stroke in the context of Evans syndrome.
