Pernicious anemia in a young Bahraini female.

Pernicious anemia (PA) is an autoimmune disorder associated with atrophic gastritis, presence of antibodies to gastric parietal cells and intrinsic factor (IF) and vitamin B2 malabsorption leading to megaloblastic anemia. It has a comparatively higher prevalence in people of North European origin, is uncommon in Arabs and usually affects the elderly. This report, the first from Bahrain, describes a rare case of PA in young female. The presenting symptoms, clinical and laboratory features were similar to those described in classical elderly Caucasian patients. No association with any other autoimmune disease was detected.
