A dental infection triggered an attack of red blood cell destruction, or hemolysis, in a man in his 40s with cold agglutinin disease (CAD), according to a case report from Japan that, researchers say, highlights the need for CAD patients to maintain good oral hygiene. Previous studies have reported…

Treatment with rituximab — commonly used off-label for cold agglutinin disease (CAD) — was found to improve biomarkers of red blood cell destruction in people with CAD, but these benefits were often short-term and reversed within a few months, according to a real-world study in the U.S. The study also…

Thrombotic events (TE), or the blockage of blood flow due to blood clots, are relatively common among adults with cold agglutinin disease (CAD) and other forms of autoimmune hemolytic anemia (AIHA), according to a study in France. Researchers also found that experiencing five or more hemolytic attacks marked by…

Up to about 1 person in 100,000 in the U.S. is estimated to be diagnosed with primary cold agglutinin disease (CAD) each year and up to 3 in 10,000 people are living with the disease, a study that analyzed 2016-2023 data from national claim databases suggests. Primary CAD…

A 76-year-old woman with cold agglutinin disease (CAD) underwent an emergency upper endoscopy, a procedure to look at the upper gastrointestinal tract, without any disease-related complications, thanks to warming strategies that prevented her body temperature from getting too low, a study shows. Such strategies included raising the temperature of…

A man developed cold agglutinin disease (CAD) shortly after receiving a COVID-19 vaccine, which ultimately led to the diagnosis of an underlying blood cancer known as diffuse large B-cell lymphoma (DLBCL), according to a recent case report. While COVID-19 vaccines are considered safe and effective, the authors emphasized the…

Warming strategies to prevent body temperature from dropping enabled a 42-year-old woman with cold agglutinin disease (CAD) to undergo a hysterectomy under general anesthesia without any disease-related complications, a study shows. “Comprehensive strategies — including measures to promote heat production, maintain core temperature, and prevent redistributive hypothermia — are…

A middle-aged woman in Iran with a history of Raynaud’s phenomenon was found to have cold agglutinin disease (CAD) after developing blue-tinged skin, known medically as acrocyanosis, and other severe symptoms, according to a case report highlighting the importance of early diagnosis and treatment in CAD. Raynaud’s…

A 79-year-old woman developed cold agglutinin disease (CAD) secondary to a rare, aggressive type of blood cancer called intravascular large B-cell lymphoma (IVLBCL), a case study reports. B-cell lymphomas are a form of blood cancer that affects B-cells, the type of white blood cell that produces antibodies, including those that…

Cold agglutinin disease (CAD) appears to be the most common type of autoimmune hemolytic anemia (AIHA) — a group of autoimmune diseases marked by attacks on red blood cells — that is triggered by COVID-19, according to a review of published studies. Patients developed AIHA about 13 days after…
