This observational study was done on 52 cases of predialysis chronic kidney disease (CKD) patients with chronic anaemia. The aim of the study was to determine the tissue iron status, comparison of the tissue iron with serum iron profile and justification of giving iron in chronic kidney disease (CKD) patients on the basis of serum iron profile. Bone marrow iron stain was done in each case and compared with the serum iron profile. The mean age of the patients was 46.8 ± 12.6 years and the mean haemoglobin and serum creatinine levels of the study population were 9.36 ± 2.13 gm/dl and 8.0 ± 4.2 mg/dl respectively. Stainable iron deposits were present in 40 (77%) cases. The mean serum ferritin and transferin saturation (TSAT) of the 52 cases were found to be 412.9 ng/ml and 28.3% and that for the 12 iron deficient cases were 101.8 ng/ml and 23.8%. Over all normal (>100ng/ml <500ng/ml), increased (>500ng/ml) or low (>100 ng/ml) serum ferritin was found in 28 and 15 and nine cases respectively. On the other hand, normal (>20% >50%) and low (>20%) TSAT were found in 31 and 12 cases, and high TSAT (>50%) in only nine cases. Out of the 12 cases having no evidence of stainable iron in the marrow low serum ferritin and low TSAT were found in eight (66.6%) and six (50%) cases, and high TSAT and either normal or high serum ferritin in six (50%) & four (33.3%) cases respectively. Low TSAT was also found in six (15%) cases of those having iron deposits in the marrow. It is, therefore, concluded that absence of stainable iron in the bone marrow is a better evidence of iron depletion than the serum iron profile and that serum ferritin and TSAT correlate less well with the bone marrow iron status in patient with chronic kidney disease.
