During the past decade, intravenous iron supplementation to ESA (erythropoiesis-stimulating agent) therapy has emerged as an option to augment hemoglobin response in anemic cancer patients. In this paper, the results of seven published randomized clinical trials assessing the role of iron supplementation to ESA therapy in the hematology/oncology setting will be discussed. The pathogenetic mechanisms behind functional iron deficiency, a major reason for ESA hyporesponsiveness in cancer, will also be described.

Post transplant anemia (PTA) is a common issue in kidney transplant recipients. Most importantly it is associated with an impaired allograft function. Other important factors associated with PTA are immunosuppressive drugs (MPA, AZA and SRL), iron deficiency, infections (Parvo B19), older donor age, rejection episodes, an increased inflammatory state, and erythropoietin hyporesponsiveness. As there are no adequately powered RCTs in the kidney transplant population on anemia treatment with ESA, we have to rely on what we know from the large RCTs in the CKD population. The recently published KDIGO guidelines do not recommend treatment with ESA if Hb is >10 g/dl. Repletion of iron stores is emphasized. Post transplant leukopenia (PTL) and thrombocytopenia (PTT) are frequent complications especially in the first six months after kidney transplantation. Myelosuppression caused by immunosuppressive agents (MPA, AZA, SRL, rATG), antimicrobial drugs (VGCV), and CMV infection is the predominant cause. There are no widely accepted guidelines on treatment strategies, but most often dose reduction or discontinuation of causative medication is done. Most clinicians tend to decrease MPA dose, but this is eventually associated with an increase in acute rejection episodes. VGCV dose reduction (preemptive treatment instead of CMV prophylaxis) may be a successful strategy. In severe cases G-CSF treatment is an important management option and seems to be safe.

INTRODUCTION. The objective of this survey was to describe the nephrologists attitude on the diagnosis and treatment of patients with non-dialysis Chronic Kidney Disease (CKD stages 3, 4 and 5), with iron deficiency anemia and no response/intolerance to oral iron therapy. Furthermore, this survey describes the nephrologists view about the impact of lack of anemia correction on patient health, as well as the influence of organization and management of nephrological centers on IV iron management. MATERIALS AND METHODS. 60 nephrologists were interviewed via web by using an interactive simulation that investigates nephrologists clinical and therapeutic approach on 3 different types of patients; subsequently, a questionnaire was administered with in-deeper questions. RESULTS. Regarding the first virtual patient, 64% of nephrologists still choose oral iron, while IV iron was chosen by 16% of them. 36% opted for ESA. For the other two virtual patients the most selected treatments were combinations of oral iron + ESA (42% and 36%) or IV iron + ESA (21% and 38%), respectively. According to what was perceived by nephrologists, issues related to IV iron are: patient discomfort due to frequent hospital transfers for IV administration (50%), inadequate center organization (48%), fear of damaging the venous tree (40%). CONCLUSIONS. Half of the nephrologists stated they are unsatisfied with available iron therapies. Difficult therapy management and restrictions of health structure were identified as barriers to the prescription of IV iron therapy. A smaller number of administrations and less free-iron toxicity are expected from nephrologists from the new iron preparations for the management of iron deficiency in patients not responding/intolerant to oral iron therapy.
