[Long-term follow up of patients with pernicious anemia].Orv Hetil. 1990 May 13; 131(19):1007-10.OH
The authors give several data of 357 patients with megaloblastic anaemia diagnosed, treated and controlled between 1958-1988. 334 of the patients had anaemia perniciosa and 23 of them had postresectional megaloblastic anaemia. After listing the criteria of the diagnosis the authors detail the mean age of the patients at the time of diagnosis, the distribution of sexes, age and blood groups among the patients, the number of new cases per year, the frequency of relapsus of the disease and its association with other autoimmune diseases. They also deal with the characteristic seasonal fluctuation and the accumulated cases in families. Its association with malignant tumours, especially with stomach carcinoma was examined.
