摘要
Objectives To study the change in plasma hemoglobin concentration in elderly patients with primary hypertension and/or type 2 diabetes complicated with end-stage renal disease （ESRD） determined by estimated glomerular filtration rate. Methods Two hundred and thirty cases of Chinese patients aged 60 years or older with primary hypertension and/or type 2 diabetes complicated with chronic kidney disease were enrolled in the study. Patients with chronic kidney disease were divided into ESRD group with estimated glomemlar filtration rate less than 15 mL . min^-1.1.73 m^-2 （7.80 ± 3. 14 mL. min^-1 . 1.73 m^-2） and non-ESRD group with estimated glomerular filtration rate 15 mL.min^-1 . 1.73 m^-2（29. 76 ± 12. 90 mL.min^-1 . 1.73 m^-2） or higher. The plasma hemoglobin concentration was compared between the above two groups retrospectively. Results There was significant decrease in plasma hemoglobin concentration in ESRD group compared with non-ESRD group （74.4 ± 22. 5 g/L vs 100. 8 ± 23.0 g/L, P 〈 0. 05 ）. After stratification by sex, there was also significant decrease in plasma hemoglobin concentration both in male and female of ESRD groups compared with their respective non-ESRD groups（77. 2±22. 0 g/L vs 104. 9 ±20. 7 g/L; 69. 7 ±22. 8 g/L vs 96.4± 24.8 g/L, P 〈 0. 05, respectively）. Plasma hemoglobin concentration was positively related to estimated glomerular filtration rate significantly in patients with ESRD （ P 〈 0. 05 ）. Conclusions Plasma hemoglobin concentration is decreased significantly, and is positively related to estimated glomerular filtration rate significantly in elderly patients with primary hypertension and/or type 2 diabetes complicated with ESRD determined by estimated glomerular filtration rate.
