In patients with IDA secondary to CBL, FCM significantly reduces the need of transfusions and achieves transfusion independence in half of the cases.

By using RNA slot-blot technique, the frequency and the degree of GST pi and mdr-1 gene coexpression were investigated in 23 AML patients, 9 ALL, 9 CLL and 11 cases of NHL in an attempt to study their clinical and prognostic relevance. GST pi and mdr-1 levels were expressed as arbitrary units (U) with respect to the negative controls (U = 0), MCF7 and HL60 sensitive cell lines, and the positive controls (U = 10), MCF7/DOXO and HL60/DNR resistant cell lines. The concomitant GST pi/mdr-1 gene overexpression showed a negative prognostic value in the set of newly diagnosed AML pts (10 cases), furthermore higher GST pi and mdr-1 mRNA levels were averagely detected in the relapsed/resistant ALL pts (4 cases), and in CLL (7 cases) and NHL (8 cases) heavily pretreated patients who were unresponsive to chemotherapy and with a disease progression. These preliminary data show that two different mechanisms of drug resistance can be coexpressed at the same time in those leukemias and lymphomas with a clinically unfavourable course.

BACKGROUNDAsymptomatic severe iron deficiency anemia is a common finding in subjects admitted to the outpatient anemia clinic. Although the condition can be easily be reversed with intravenous iron (IVI) therapy and several guidelines have suggested a restrictive threshold for using transfusion in hemodynamically stable patients, transfusion is often the rule in clinical practice. This study describes clinical practice results of IVI therapy without transfusion.STUDY DESIGN AND METHODSIn this multicenter retrospective observational study, data of severely anemic outpatients treated only with high‐dose IVI with ferric carboxymaltose were collected. Inclusion criteria were hemoglobin (Hb) level of less than 7.0 g/dL and ferritin level of less than 30 ng/mL or mean corpuscular volume of less than 75 fL.RESULTSOverall, 303 patients referred to the anemia clinic mainly from primary health care centers (46.2%) or the emergency department (28.7%) met the inclusion criteria. Median (interquartile range [IQR]) age was 47 (37‐62) years and 84.5% were female. The median (IQR) Hb concentration at first visit was 6.5 (6.1‐6.8) g/dL, 64 patients (21.1%) presented with a Hb level of less than 6.0 g/dL at diagnosis, and 11 of them (3.6%) had extreme anemia (Hb ≤ 5 g/dL). Gynecologic and gastroenteric bleeding were the main cause. After a mean IV administration of 1500 mg of iron, the Hb increased by a median of 5.7 g/dL. Thirteen patients experienced only mild side effects.CONCLUSIONSIn chronic very severe sideropenic anemias, third‐generation IVI is effective and safe for quick correction and avoidance of red blood cell transfusion. These results suggest that more specific guidelines for this clinical setting are warranted.
