Lupus Identified as Leading Trigger of Rare Blood Disorder in Young Women

Why it matters

Autoimmune hemolytic anemia (AIHA) is a rare condition in which the immune system mistakenly attacks and destroys the body's own red blood cells, leading to fatigue, shortness of breath and, in severe cases, death. The disorder affects roughly one to three people per 100,000 each year and carries a mortality rate of about 11%, making early detection important for anyone who experiences unexplained anemia symptoms.

What the study found

In a review of 78 patients treated at a major hospital, 83.33% were female and the average age was 26.06 years. The warm type of AIHA, in which antibodies act best at body temperature, accounted for 91.03% of cases, making it by far the most common form. When AIHA was linked to another disease (a secondary cause), Systemic Lupus Erythematosus (SLE), an autoimmune disease that can affect many organs, was the most frequent trigger. Laboratory testing showed that the strongest direct Coombs test result (+3) appeared in 47.89% of warm, 33.33% of cold and 75% of mixed cases, while the most common indirect Coombs test result was +2 in warm (30.99%) and mixed (75%) cases and +3 in cold cases (66.67%).

What it means for people

These findings help patients understand why young women may be at higher risk for AIHA and why lupus should be considered when symptoms arise. Clinicians gain clearer data on how often lupus underlies the disorder and on the typical laboratory patterns, aiding quicker diagnosis and targeted treatment. Researchers add valuable epidemiological information that can guide future studies on AIHA and its connections to other autoimmune diseases.
