A man with cold agglutinin disease (CAD) was found to have another autoimmune condition called pernicious anemia and vitamin B12 deficiency, according to researchers in the U.S. who called the case a rare instance of “three ongoing medical conditions simultaneously.” The case study, “A Case Report of Cold…

The induced reduction in body temperature during an emergency surgery to replace a damaged heart component revealed the presence of mild cold agglutinin disease (CAD) in a woman in India, a study reports. The case study, “Cardiopulmonary Bypass Surgery-Cold Alert!,” was published in Annals of Cardiac Anaesthesia.

Four rare disease advocacy groups have been chosen by the National Organization for Rare Disorders (NORD) to take part in IAMRARE, a program that will help them launch their own patient-powered natural history studies. Rare diseases, including cold agglutinin disease (CAD) often are poorly understood, and there…

Blood transfusions may be challenging in children with cold agglutinin disease (CAD), but should remain an option for those with severe disease, a small study in India suggests. Most of the eight children with CAD in the study received a blood transfusion, but none were complete matches in terms…

Multiple strategies to keep a woman with cold agglutinin disease (CAD) sufficiently warm right before and during hip replacement surgery allowed for a safe procedure and the absence of post-surgery complications, a case study shows. One way to reduce heat loss — and therefore prevent disease worsening — was…

A woman with cold agglutinin disease (CAD) secondary to a cancer also developed bilateral retinal vasculitis — inflammation of the blood vessels found at the back of both eyes — in what researchers claim to be “the first report of retinal vasculitis in a patient with CAD.” Initial treatment…

A test called Hevylite was superior to standard methods at detecting immunoglobulin M (IgM) — a type of antibody associated with cold agglutinin disease (CAD) — in the blood of people with the disease, a small study has shown. This suggests that Hevylite, sold by Binding Site,…

An elderly woman in Japan is the first reported patient in Asia to develop cold agglutinin disease (CAD) due to COVID-19, according to a new case study. The patient was found to have anemia, or an unusually low red blood cell count, that was not resolved with a blood…
