Randomized Controlled TrialA Prospective Randomised Controlled Trial of a Single Intravenous Infusion of Ferric Carboxymaltose vs Single Intravenous Iron Polymaltose or Daily Oral Ferrous Sulphate in the Treatment of Iron Deficiency Anaemia in Pregnancy.
Iron deficiency anaemia (IDA) is the most common nutritional deficiency affecting pregnant women worldwide. This study aims to compare the efficacy and safety of a newly available intravenous (IV) iron preparation, ferric carboxymaltose (FCM), against IV iron polymaltose (IPM), and standard oral iron (ferrous sulphate) for the treatment of IDA in pregnancy. This is an open-labelled prospective randomised controlled trial (RCT) with intention-to-treat analysis conducted at a primary health care facility with a single tertiary referral centre in Launceston. ⋯ Rapid parenteral iron repletion can improve iron stores, Hb levels and QoL in pregnant women, with ongoing benefits until delivery. Integration of IV iron for IDA in pregnancy can potentially improve pregnancy outcomes for the mother. Update of guidelines to integrate the use of new IV iron preparations in pregnancy is warranted.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialQuality of life on imatinib.
Imatinib (Gleevec), a highly effective specific tyrosine kinase inhibitor, demonstrates a better side effect profile than interferon-alpha (IFN), which impairs patients' quality of life (QoL). This phase III international study evaluated QoL outcomes in 1,106 newly diagnosed patients with chronic-phase chronic myeloid leukemia (CML) who were randomized to receive either imatinib 400 mg daily or IFN up to 5 MU/m(2)/d with cytarabine (Ara-C) 20 mg/m(2)/d added for 10 days every month (IFN + LDAC). Crossover to the other treatment arm was permitted due to a lack of efficacy or treatment intolerance. ⋯ Imatinib offers clear QoL advantages over IFN as first-line treatment of chronic-phase CML. In addition, patients who crossed over to imatinib reported higher QoL than those who remained on IFN. Semin Hematol 40(suppl 2):31-36.

Randomized Controlled Trial Multicenter Study Clinical TrialImatinib in patients with newly diagnosed chronic-phase chronic myeloid leukemia.
The International Randomized Study of Interferon and STI571 (IRIS) study prospectively compared imatinib with interferon-alpha/low-dose cytarabine (IFN/LDAC) in 1,106 newly diagnosed patients with Philadelphia chromosome-positive chronic myeloid leukemia (CML). Patients not responding to or intolerant of their assigned treatment were allowed to cross over. At 18 months, the projected probability of achieving a complete cytogenetic response was 76.2% for imatinib and 14.5% for IFN/LDAC, respectively (P <.01). ⋯ Most cross-overs to imatinib were due to interferon-intolerance. Overall survival was not different in the two groups at 19 months, reflecting efficient rescue of IFN/LDAC failures with imatinib. Imatinib should now be considered the standard therapy for newly diagnosed patients with CML.

Review Randomized Controlled Trial Clinical TrialPerioperative epoetin alfa increases red blood cell mass and reduces exposure to transfusions: results of randomized clinical trials.
To avoid the inherent risk of complications associated with perioperative allogeneic transfusion, preoperative autologous blood donation (PAD) is frequently employed by patients undergoing major elective surgical procedures. However, many patients are unable to donate a sufficient quantity of blood prior to surgery. Recent studies have shown that epoetin alfa (Procrit; Ortho-Biotech, Raritan, NJ) effectively increases red blood cell (RBC) mass when administered preoperatively and decreases the requirement for allogeneic transfusion. ⋯ Our study demonstrated that epoetin alfa is safe and effective in increasing RBC mass; however, iron stores considered sufficient for basal erythropoiesis may not optimally support the accelerated RBC production associated with epoetin alfa therapy. In a subsequent randomized multicenter trial, we compared weekly epoetin alfa dosing to daily dosing in patients undergoing elective major orthopedic surgery. The results of this study indicated that administering epoetin alfa on a weekly schedule for several weeks prior to surgery may be at least as effective and more convenient than perioperative daily epoetin alfa dosing.
