Objectives: To evaluate the relationship between serum iron and ferritin concentrations with some characteristics of chronic kidney diseases. Subjects and methods: A cross-sectional study with a study group of 124 stage 3 - 5 chronic kidney disease patients, and a control group of 66 healthy people at Department of Nephrology and Hemodialysis, 103 Military Hospital. | Journal of military pharmaco-medicine n09-2018 SURVEY ON THE RELATIONSHIP BETWEEN SERUM CONCENTRATION OF IRON, FERRITIN AND SOME CHARACTERISITICS IN PATIENTS WITH STAGE 3 TO 5 CHRONIC PREDIALYSIS KIDNEY DISEASE Nguyen Van Hung1, Nguyen Cao Luan2; Le Viet Thang3 SUMMARY Objectives: To evaluate the relationship between serum iron and ferritin concentrations with some characteristics of chronic kidney diseases. Subjects and methods: A cross-sectional study with a study group of 124 stage 3 - 5 chronic kidney disease patients, and a control group of 66 healthy people at Department of Nephrology and Hemodialysis, 103 Military Hospital. Results: The mean concentrations of serum iron in study group was significantly lower than control group ( µmol/L versus µmol/L), but the mean concentrations of serum ferritin in study group was higher than control group ( ng/mL versus ng/mL) with p 5 mg/L: diagnosed as increase. * Statistical analysis: Statistical analyses were conducted using SPSS . 115 Journal of military pharmaco-medicine n09-2018 RESULTS The study group with average age was years old, there were male; female, mean glomerular filtration rate was mL/min.
