title: Ultrastructural changes in parietal cells in iron deficiency anemia.
abstract: Eighteen patients with iron deficiency anemia (IDA) and 14 age and sex matched control subjects were studied with regard to ultrastructural changes in parietal cells. The control subjects had normal hemoglobin and serum iron levels and endoscopic examination of the upper gastrointestinal tract. Thirteen cases of iron deficiency anemia had chronic superficial gastritis on light microscopy. Ultrastructural abnormalities in the parietal cells, such as indented or pyknotic nucleus with irregular outline, grossly distorted canalicular system, abnormal large empty spaces in the cytoplasm and paucity of mitochondria, were demonstrated in all IDA patients but not in controls. The presence of superficial gastritis and ultrastructural changes were not related either to hemoglobin or serum iron levels in the IDA group.
