Abstract

Renal transplantation is the treatment of choice for the end-stage renal disease. Hypervolemia and inflammation are commonly overlooked. We investigated whether hyper-volemia develops in kidney transplant recipients with estimated glomerular filtration rate (eGFR) >70 mL/min and if there is there any correlation between inflammatory cytokines and hypervolemia in the 1st month and at six months after transplantation. We measured serum tumor necrosis factor-α (TNF-α), interleukin (IL)-1, IL-6, and body composition indices in 11 healthy volunteers and 19 kidney transplant recipients (KTRs) with eGFR >70 mL/min at one month and six months posttransplant. At baseline, body mass index (BMI) and fat tissue index (FTI) were significantly higher and overhydration improved (P = 0.006) at 6th month in KTRs. There was no difference in BMI, FTI, lean tissue index (LTI), and serum levels of IL-1 and IL-6 in controls and KTRs at six months posttransplant. Volume overload and serum TNF-α levels were significantly lower in controls than KTRs. There was positive correlation between volume overload and serum TNF-α levels in KTRs. Compared to baseline, parameters including volume overload, BMI, and FTI were found to be improved at six months' post...Continue Reading
