[Coexistence of Addison-Biermer's disease with autoimmune thyroiditis - case report]

Addison-Biermer's anaemia is an autoimmune disease and the most common cause of vitamin B12 deficiency. Hashimoto disease is the most common type of the thyroiditis and also has autoimmunological origin. Frequent coexistence of both mentioned entities has been observed. In the paper we report a case of a woman, who was diagnosed with pernicious anaemia (PA) with predominant neurological symptoms and concomitant autoimmune thyroiditis. Many efforts have been made in order to explain frequent coexistence of mentioned diseases. Both genetic (mainly HLA region genes) and environmental (mostly bacterial infections) factors are considered. The aim of the study (was to emphasize significance of diagnosing thyroid gland diseases among PA patients. It is also important to remember that neurological symptoms are frequent in the course of PA and may precede other complaints. However it should not prevent the right diagnosis.
