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…

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,…

Cold agglutinin disease (CAD) was the likely trigger of repeated mini-strokes in an 84-year-old woman with already compromised blood flow in the brain due to severe narrowing of a major artery that supplies blood to the brain, according to a case report from Portugal. The underlying mechanisms of red…

Treatment with rituximab — commonly used off-label for cold agglutinin disease (CAD) — was reported to successfully resolve a serious case of CAD secondary to an Epstein-Barr virus (EBV) infection and potential contraceptive pill toxicity in a young woman in Europe. The woman had developed severe jaundice and liver…

Zydus Lifesciences’ desidustat eases the anemia and red blood cell destruction that mark autoimmune hemolytic anemia, or AIHA, a group of autoimmune conditions that includes cold agglutinin disease (CAD), a study in a mouse model has found. The oral therapy was shown to stimulate red blood cell production…

Parsaclisib, an experimental oral therapy from Incyte, safely and effectively increased levels of hemoglobin in about half of people with cold agglutinin disease (CAD) in a small Phase 2 clinical trial, a study shows. Data from the study (NCT03538041), which included people with other forms of autoimmune…

Restarting Enjaymo (sutimlimab) after stopping it for up to four months was generally safe and brought blood markers of cold agglutinin disease (CAD) back to levels before its cessation. These are the findings of a Japanese open-label extension (OLE) study wherein seven CAD patients who completed one of…

How childhood autoimmune hemolytic anemia (AIHA) — a group of rare conditions that includes cold agglutinin disease (CAD) — is defined and classified varies widely, as does the approach to care for children with hard-to-treat disease, a review study shows. “Standardized definitions and classifications are needed to guide collaborative efforts…

The detection of cold agglutinins, the self-reactive antibodies that drive cold agglutinin disease (CAD), was crucial for the correct diagnosis and management of anemia — lower than normal levels of red blood cells or hemoglobin — in a 37-year-old man with several traumatic injuries after a motorcycle accident, according…

A woman in Costa Rica developed cold agglutinin disease (CAD) secondary to a diagnosis of systemic lupus erythematosus (SLE) that was complicated by nephritis, a serious kidney inflammation that often occurs with this form of lupus. CAD “is exceptionally rare in SLE, with few cases being reported in…
