Anaemia was recorded in 41% of study subjects, estimated using K/DOQI recommendations. The prevalence of anaemia was increased from 30.2% to 44.8% of study patients with a rise of BP (from normal BP to hypertension; P &lt; 0.05). The mean Hb level at the start of RRT was 9.8 ± 2.1 g/dl. Only 18% of patients with renal anaemia had used erythropoiesis-stimulating agents before RRT (28 of 155). Anaemia is the prevalent condition at moderate degrees of CKD. The severity of anaemia in the CKD population is determined by evidence of diabetes, cardiovascular disease, and renal function. Anaemia may often be unrecognised or untreated.</p></abstract>

Chronic kidney disease (CKD) is a significant and prevalent health problem in the world. Anaemia is one of the most common manifestations in patients with CKD. The correction of anaemia with erythropoietin normalises haemoglobin level and improves quality of life.
