Italian randomized trial of hemoglobin maintenance to prevent or delay left ventricular hypertrophy in chronic kidney disease

This study is part of a 3-country study testing whether normal levels of hemoglobin (Hgb) delay the progression of left ventricular (LV) growth in chronic kidney disease (CKD) patients not on dialysis. This was an open-label, randomized, multicenter, controlled trial conducted in 27 tertiary-care hospitals in Italy. Treated subjects (n=46) received epoetin-alpha (EPO-alpha) to maintain Hgb levels in the range 12-14 g/dL. Control subjects (n=49) were not treated unless their Hgb decreased to 9.0 g/dL. Primary outcome was LV mass index (MI) change after 24 months. Subcutaneous EPO-alpha was withdrawn in Europe and the study prematurely terminated; therefore, a 12-month analysis was carried out. Mean age was 57 years (38% were women, 18% with diabetes, 76% taking ACEI or ARB and 22% statins). EPO-alpha median final dose was 2,000 IU/week. Hgb significantly increased (12.4 -/+ 1.1 g/L) for the treatment group and decreased for controls (11.3 -/+ 1.3 g/L; p
