title: Association of secondary hyperparathyroidism with hemoglobin level in patients with chronic kidney disease.
abstract: OBJECTIVE
  Secondary hyperparathyroidism (SHPT) is one of the less recognized reasons of anemia in chronic kidney disease (CKD). In this study, we evaluated the role of SHPT as a cause of anemia and correlation of intact parathyroid hormone (iPTH) and hemoglobin (Hb) level in hemodialysis (HD) patients.
  
  
  METHODS
  This cross-sectional study was carried out in 63 individuals admitted in HD unit of the institute. Serum samples were collected and urea, creatinine, Hb, ferritin and iPTH levels were measured. Statistical analysis was carried out using the SPSS software (IBM, NY, USA).
  
  
  RESULTS
  Mean ± standard deviation for serum urea, creatinine, Hb, ferritin and intact PTH were 177 ± 15.52, 15.16 ± 2.28 mg/dl, 7.03 ± 2.26 g/dl, 654.7 ± 563.4 ng/ml, 539.18 ± 493.59 pg/ml respectively. A reverse correlation was found between intact PTH and Hb level.
  
  
  CONCLUSIONS
  A variety of postulated pathophysiological mechanisms linking SHPT and anemia in CKD are discussed. An efficient control of parathyroid hormone hypersecretion may be required to achieve a better management of anemia in HD patients.
