Iron stores in essential thrombocythaemia. A study of 26 patients.
Postgraduate School of Haematology Farreras Valentí, University of Barcelona, Spain.Blut 07/1989; 58(6):291-4.
The iron status of 26 patients with essential thrombocythaemia (ET) was evaluated at diagnosis by means of bone marrow iron and blood studies, including serum ferritin determination. Nine patients were males, 17 females, and the mean age was 53 years (range 7-81). A decreased or absent iron level by semiquantitative estimation on bone marrow smears was observed in 77% of patients, and 81% had a low sideroblast score. Such a marrow pattern of iron depletion was equally distributed between both sexes. Contrasting with this, normal Hb, MCV, serum iron and serum ferritin were registered in the majority of cases. According to these results, absent or decreased marrow iron would be a common feature in ET, generally not reflecting true iron deficiency, as it occurs in the remaining chronic myeloproliferative disorders. Thus, in patients in whom ET is suspected, the diagnostic criterion of ruling out iron deficiency would be better served by serum ferritin measurement than by bone marrow iron estimation.

ABSTRACT: Stainable iron was absent or decreased in 36 of 45 bone marrow biopsy specimens (80 percent) among 33 patients with chronic-stage chronic granulocytic leukemia. Decreased iron did not correlate with sex, treatment status, duration of disease, marrow cellularity, or hemoglobin level. In contrast, marrow iron was absent or decreased in 34 percent of biopsy specimens at diagnosis of acute nonlymphocytic leukemia (p less than 0.0001) and 31 percent of biopsy specimens from patients with Hodgkin's disease (p less than 0.0001). The serum ferritin level was determined in eight patients with chronic granulocytic leukemia and absent marrow iron, and it was normal in all. Fifteen of 17 patients, followed with chronic-stage disease for one to four years after the finding of absent marrow iron, demonstrated increases in their hemoglobin levels during antileukemic therapy or maintained normal values. Thus, absent or decreased stainable marrow iron is a common finding in chronic granulocytic leukemia and usually does not indicate iron deficiency.The American Journal of Medicine 10/1986; 81(3):395-9.
