A high RBC count combined with a low mean volume generally is attributed to thalassemia minor, either alpha or beta, or to polycythemia vera with iron deficiency. Among 330 patients with a mean corpuscular volume (MCV) less than 70 cumu, 35 had increased RBC counts. Of these, 26 had thalassemia minor and four had polycythemia vera. Five had secondary polycythemia (four from hypoxia, one from hypernephroma) with incidental iron deficiency. In the four of these patients given iron, the RBC count remained above normal and the MCV rose to normal. The RBC size distribution curves reliably distinguished between thalassemia minor and polycythemia with iron deficiency.

In myeloproliferative disorders many complications are caused by circulatory problems due to high leukocyte or platelet numbers and by hyperviscosity. With cytaphereses and mild cytostatics like Azathioprine, these problems are solved quickly and without major side effects. We report about plateletaphereses for polycythemia vera and megacaryocytic myelosis and leukocytaphereses for chronic myelogenous leukemia. In addition, erythrocytaphereses were carried out successfully in a patient with a combination of heterozygous sickle cell anemia and thalassemia minor.
