Evaluation of plasma zinc and copper in patient with chronic renal failure in Khartoum State - Sudan

The kidney is complex vital organs, and has many functions. The main function it‘s removal of toxic and excess  substancesfrom the plasma, if there is any defect in the kidney like renal failure can disrupt  this function. The aim of this study was to determine the level of Zinc and Copper in Sudanese patient with chronic renal failure. This study was designed as case control, which includes 100 blood samples, a 60 from these sample were collected from patient with chronic renal failure and 40 samples were collected from health individual as control group and the sample is collected by using sterile disposable syringes and separated by centrifuge. Carried out in Ribat University Hospital in Khartoum state, during period from March to June 2018. And the plasma levels of zinc and copper determined by the use of atomic absorption spectrophotometer (OPERATOR’S MANUAL January 2003 VER 3.94 C), and the obtained results were analyzed by SPSS. The result of this study showed that there was significant decrease (p<0.05) in the plasma levels of zinc and copper in patient with chronic renal failure compared to the control subjects. The mean of plasma Zn was 0.3mg/l in test group and 0.7mg/l in control group with p. value of 0.002 and the mean of plasma Copper was 0.5mg/l in test group and 0.7mg/l in control group with p. value of 0.019. Also the study showed the gender and age of the patient, also the duration of the disease have no effect on the plasma level of zinc and copper (p 0.05). The study concludes that the plasma level of zinc and copper are low in patient with chronic renal failure. And the gender and age of the patient also the duration of disease have no significant effect on the plasma level of zinc and copper. Keywords: Chronic Renal Failure, Zinc, Copper, Sudanese
