We report a case of a 59-year-old woman with metastatic carcinoma of the ileocecal region who received FOLFOX(oxaliplatin/leucovorin/5-fluorouracil) and bevacizumab therapy and exhibited a partial remission with minimal side effects. She developed a mild self-limited episode of immune-mediated hemolytic anemia during her 16th cycle of chemotherapy, which precluded her from receiving further oxaliplatin. We review the literature on oxaliplatin-induced immune-mediated hemolysis, including its mechanism, presenting symptoms, laboratory features, management, and implications for future therapy.

Objective: To determine if oxidative stress induces phosphatidylserine (PS) externalization in canine erythrocytes and if exposure to antioxidants prevents such changes.
Methods: This was an in vitro, experimental study using 5 healthy, adult, purpose-bred research Beagles. Fresh EDTA-anticoagulated blood samples were collected from each dog, and erythrocytes were harvested.

Autoimmune hemolytic anemia (AIHA) is a multifactorial disease that causes immune-mediated red blood cell destruction, resulting in anemia and hemolysis symptoms. Despite a significant understanding of its pathogenesis, the precise causes of AIHA remain largely unclear and are thought to be multifactorial. In this paper, we presented a case of sickle cell anemia who developed severe AIHA that failed to maintain response to multiple treatment lines, including steroids, intravenous immunoglobulin, rituximab, and immune suppressive medications.

Thrombotic microangiopathies (TMA) are a group of conditions that present with varying degrees of microthrombi, thrombocytopenia, microangiopathic hemolytic anemia, renal dysfunction, and neurological impairment. Etiologies can be primary, such as thrombotic thrombocytopenic purpura (TTP), hemolytic uremic syndrome (HUS), and atypical hemolytic uremic syndrome (aHUS), or secondary, such as due to systemic infections, malignancies, immune-mediated conditions, and hypertensive emergencies. In hypertensive emergencies, this presentation can occur from mechanical stress placed on red blood cells as they pass through narrowed arteries due to edema and microangiopathic changes within the vessels themselves.

The presence of erythrocyte ghost cells (EG) in blood smears indicates intravascular haemolysis or in-vitro haemolysis. However, observer reliability in detection of EG has not been documented. Immediate blood smear preparation is advised but may not always be practical.
