Independent correlation between ischemia modified albumin and parathormone in hemodialysis patients

Introduction. Hemodialysis patients are the group which oxidative stress is found more exacerbated. Ischemia modified albumin (IMA) is a new and sensitive marker for ischemia and oxidative stress. At current study we evaluated relation between IMA and biochemical parameters in hemodialysis patients. Materials and Methods. Thirty-four patients on maintenance hemodialysis were included. Pre-hemodialysis and post-hemodialysis blood samples were taken. Serum IMA and biochemistry parameters were measured. Results. There was a positive correlation between alkaline phosphatase (ALP) and IMA (r=0,268, p<0,05), CRP and IMA (r=0,452, p=0,007), parathormone and IMA (r=0,436, p=0,010), There was a negative correlation between albumin and IMA (r=-0,338, p=0,05). Multiple regression analysis was run to predict IMA levels from parathormone, CRP and creatinine the model statistically significantly predicted relation p<0,05, R=0,506, out of four two variables added statistically significant to the prediction, PTH (p=0,006), CRP (p=0,029). In multiregression analysis, IMA was found to be associated with PTH and CRP independent of creatinine value. Conclusions. We showed for the first time that PTH is associated with IMA in hemodialysis patients, independent of the level of renal function.
