Atypical hemolytic uremic syndrome (aHUS) is an important differential diagnosis in thrombotic microangiopathy (TMA). The absence of definitive biomarkers usually allows for aHUS to be diagnosed only through a process of exclusion. Due to the unfavorable prognosis if adequate therapy is delayed or not provided, differential diagnostic considerations and initiation of treatment must occur promptly.

An 83-year-old female patient presented with angina pectoris, hemoglobinuria and jaundice. Laboratory diagnostics proved difficult due to hemolysis in all blood tubes, following re-evaluation after warming the blood sample.With low haptoglobin, elevated lactate dehydrogenase and elevated indirect bilirubin, we made a suspected diagnosis of autoimmune hemolytic anemia with cold antibodies, which was confirmed through a positive Coombs test and detection of C3d-loaded erythrocytes.

Transplantation-associated thrombotic microangiopathy (TMA) is a severe complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with high mortality. As calcineurin inhibitors (CNIs) reportedly contribute to TMA via drug-induced endothelial injury, treatment of TMA often involves CNI discontinuation or dose reduction. However, renal-limited TMA, defined as biopsy-proven renal TMA without the classical triad (hemolytic anemia, thrombocytopenia, and organ damage), has rarely been reported after allo-HSCT, and its optimal management remains unknown.

Hemolytic anemia (HA) is characterized by massive destruction of red blood cells (RBCs) and insufficient oxygen supply, which can lead to shock, organ failure, even death. Recent studies have preliminarily demonstrated the therapeutic effectiveness of whole blood exchange (WBE) in the management of acute hemolytic anemia and exhibited potential for reducing the duration of corticosteroid treatment, while the underlying mechanism of WBE therapy was not investigated in preclinical study. Hence, we investigate the therapeutic mechanisms of WBE in HA through established continued WBE therapy in rats creatively.

Hydroxyurea (HU) is frequently used in the treatment of various myeloproliferative neoplasms (MPN) where it reduces cell proliferation by impairing DNA synthesis leading to decreased hematopoiesis. Herein we report a case of a 65-year-old female who was diagnosed with Chronic myeloid leukemia and developed severe hemolytic anemia requiring multiple packed red blood cell (RBC) transfusions while being treated with hydroxyurea. The haemolysis persisted until discontinuation of the drug.
