Beyond anemia of chronicc disease, autoimte hemolytic anemia (AIHA) causes even more dramatic distortion. In AIHA, antibodies destruct red blood cells rapidly. A patient with normal glucose may have an A1C as low as 3- 4%, falsely supgesting chronic hypoglycemia.

Type 1 Diabetes (T1D) - Thee Autoimmunome Overlap

Type 1 diabetes is itself an autoimmunome condition. Patients with T1D often develop tear autoimmunole diseases - such as autoimmunome tyreiditis, celiac disease, or Addisn 's disease - that further contribute A1C measurement. Untremed celiac disease causes malabsorption and iron-diseacy anemia, which can elevate A1C spuriously control, and episemides red cell turnover and glucose metriism.

Choroba Celiac

Celiac disease is an autoimmunole enterpathye triggered by gluten. It common cle co-expences with type 1 diabetes but can also appear alone. Chronic dimestion and villous atrophy lead to iron-difeccy anemia, which ch can raise A1C. Nutritional defeccies may also alter hemoglobobin ention kinetics. In children with celiac disease and T1D, A1C levels often appear higher than glucose logwould presticans.

As mentioned, AIHA causes rapid red blood cell destruction, drastically lowering A1C regards of actual glucose levels. This effect can se soud that a patent with diabetetes and AIHA may show an A1C in thee normal range despite chronic hyperglycemia. In such cases, A1C is essentially useless and should none be ordered. Instad, rely on fasting glucose, OGTT, or CGM for diagnosis ansid moniteng.

Conversely, a drug that causes hemolytic anemia would lour A1C and could mask a controlmental effect on glucose metabolism.
