Nearly half of children and teens with autoimmune hemolytic anemia (AIHA) — a group of disorders that includes cold agglutinin disease (CAD)  — have signs of erythrophagocytosis, or the removal of old and damaged red blood cells by immune cells, in blood samples, a small study shows. While erythrophagocytosis…

Few cases of cold agglutinin disease (CAD) secondary to systemic lupus erythematosus, or SLE, have been reported over the past seven decades, but all occurred in women, according to a study by two researchers in Colombia. In addition to describing two new cases of CAD secondary to SLE —…
Clinicians detected B-cell lymphoma, a type of blood cancer, in a 53-year-old man two years after he was diagnosed with cold agglutinin disease (CAD) marked by anemia, or low counts of red blood cells, but no symptoms, a case study indicates. All signs of lymphoma and CAD disappeared after…

A man with rheumatoid arthritis and cold agglutinin disease (CAD) achieved complete remission following treatment with rituximab, an antibody-based therapy commonly used off-label for CAD, a recent case study indicates. Rituximab therapy also treated the man’s cooccurring immune thrombocytopenia, an autoimmune disorder marked by the destruction of platelets, which…
A Japanese man with severe anemia — a condition marked by too few red blood cells in the body — following a case of COVID-19 tested positive for cold agglutinins and cryoglobulins, two types of antibodies that become reactive in the cold, according to a new report. Cold agglutinins are…
Very low doses of rituximab rapidly reduced blood levels of disease-driving B-cells in people with cold agglutinin disease (CAD) and other forms of autoimmune hemolytic anemia (AIHA), but this suppression was not consistently sustained over time. Those are the findings of a small pilot Phase 2 clinical…
Warming and an extra dose of corticosteroid medication were part of multiple strategies doctors used to allow for a safe Cesarean section (c-section), without complications, in a pregnant woman with cold agglutinin disease (CAD), according to a case report. The woman was kept warm right during her hospital stay,…
