A 4-year-old girl presented with severe pallor and intermittent passage of cola-coloured urine. Routine investigations were suggestive of auto-immune haemolytic anaemia. Red cell agglutination was observed in peripheral smear and patient's serum was positive for cold agglutinins. Thorough work-up ruled out secondary cold agglutinin disease. Patient was treated successfully with corticosteroids.

The Prevalence of Peripheral Erythrophagocytosis in Pediatric Immune-Mediated Hemolytic Anemia.
Hematol Rep
January 2025
Children's Haematology and Cancer Centre, Mount Elizabeth Hospital, Singapore 228510, Singapore.
Background: Peripheral erythrophagocytosis appears to be a unique sign of acquired immune-mediated hemolytic anemia. It is said to be rare but its prevalence among patients with autoimmune hemolytic anemia has not been studied.
Methods: In this retrospective study from July 2014 to June 2024, the clinical and laboratory features, treatment and outcomes of children diagnosed with autoimmune hemolytic anemia were described.
Intraoperative vascular anastomosis occlusion due to cold agglutinin disease during brain surgery: a case report.
JA Clin Rep

Department of Anesthesiology and Pain Medicine, Gifu University Hospital, 1-1 Yanagido, Gifu, 501-1194, Japan.
Background: Cold agglutinin disease (CAD) is an autoimmune hemolytic anemia that induces blood coagulation and hemolysis upon exposure to cold temperatures. Strict temperature control is essential to mitigate these effects, especially during surgical procedures where hypothermia is possible.
Case Presentation: A 57-year-old male, 165 cm and 72 kg, diagnosed with CAD, underwent cerebral vascular anastomosis.
Cold agglutinin syndrome as a precursor for the diagnosis of low‑grade lymphoma: A case report.
Med Int (Lond)

Department of Hematology, Dokuz Eylul University Hospital, Izmir 35000, Turkey.
Cold agglutinin syndrome is a form of acquired hemolytic anemia that typically arises from underlying conditions, such as infections, autoimmune disorders or lymphoid malignancies. The majority of patients remain asymptomatic and are diagnosed with anemia through routine complete blood count (CBC) testing. The present study describes the case of a male patient in his 50s who sought a second opinion at the authors' clinic due to newly detected anemia.

Department of Internal Medicine, Uwajima City Hospital, Uwajima, JPN.
We report a case of coexisting cold agglutinin and cryoglobulin in a patient with severe anemia following COVID-19 infection, in whom direct antiglobulin testing revealed C3d positivity and immunoglobulin G negativity. There was no evident hemolytic anemia, thrombosis, or clinically significant IgM monoclonal gammopathy. The anemia improved with folic acid supplementation alone accompanied by a decrease of the cold agglutination titer, and the direct antiglobulin test became negative.

Front Med (Lausanne)
December 2024
Department of Clinical Pharmacology, Medical University of Vienna, Vienna, Austria.
Introduction: Although rituximab is approved for several autoimmune diseases, no formal dose finding studies have been conducted. The amount of CD20+ cells differs significantly between autoimmune diseases and B-cell malignancies. Hence, dose requirements of anti-CD20 therapies may differ accordingly.
