    Abstract:
    Iron-deficiency anemia is one of the major problems encountered in renal transplant recipients. The aim of this retrospective study was to reevaluate the causes of anemia among 100 anemic kidney recipients. Patients with serum creatinine levels greater than 2 mg/dL were excluded from the study. Female patients were considered to be anemic if the hemoglobin was <12 g/dL for males, <13 g/dL. Complete blood count, serum creatinine, serum iron, iron-binding capacity, ferritin, transferrin saturation, erythrocyte folate, and serum vitamin B(12) levels were measured in all patients. Mean hemoglobin value was 10.2 +/- 1.4 g/dL for female and 9.9 +/- 1.3 for male patients, mean corpuscular volume (MCV) 91.3 +/- 4.9 fL. We observed normocytic anemia in 60, macrocytic anemia in 30, and microcytic anemia in 10 patients. A low level of serum folate was observed in 9 (15%) and of vitamin B(12) in 5 (8.8%) of 60 patients with normocytic anemia. Folate deficiency was found in 18 (60%) and vitamin B(12) deficiency in 12 (40%) of 30 patients with macrocytic anemia. All patients with microcytic anemia had iron deficiency. Splenomegaly was seen significantly more often in patients with macrocytic than normocytic anemia (P =.008). Folate and vitamin B(12) deficiency were the major causes of nutritional anemia; oral or parenteral supplementation with these vitamins is likely to cure the anemia in the majority of cases.
