NEW DEVELOPMENTS IN THE DIAGNOSIS AND TREATMENT OF PERNICIOUS ANEMIA

Abstract
In this study, 45 patients with pernicious anemia were treated with crystalline vitamin B12 given orally without intrinsic factor. When 3000-10,000 [mu]g of vitamin B12 were given orally in a single dose to patients in relapse, clinical and hematological responses resembled those seen with parenteral therapy. Patients were maintained in complete remission by the administration of a single tablet containing 1000 [mu]g once per week. Eleven patients were satisfactorily maintained on this regimen for more than 3 years.
