Assessment of Serum Zinc and Copper Levels among Sudanese Patients with Diabetes Mellitus Type 2 in Khartoum State-Sudan

Abstract

Background: Diabetes population in Sudan is around one million 90% have type 2 diabetes. In Sudan diabetes is as increasing problem, being responsible for 10% of hospital admission and mortality. Measurement of zinc and copper is an important in decrease development of complication of DM, any disturbance in level of both zinc and copper have role in pathogenesis, prognosis of type 2 DM. This study aimed to assess the relationship between DM type 2 and trace elements by measured serum zinc and serum copper levels among Sudanese DM type 2 in Khartoum state. Materials and Methods: This is a descriptive, case control study, was conducted in Khartoum state, Sudan. During the period from April to July 2018. Forty Sudanese patients with DM (20 controlled patients with DM and 20 uncontrolled patients with DM) Diabetes patients were divided into controlled and uncontrolled groups by measuring HbA1C. (Female 25% and male 15%), with different age. were selected as case and 30 apparently healthy individuals were selected as control group. Serum zinc and copper levels were analysis using Atomic Absorption Spectroscopy and ichroma for HbA1c, the obtained results were analyzed using social science software package. Results: This study showed significant lower of serum zinc in diabetes type 2 patients comparison with control group and on another hand showed significant increase of serum copper in diabetes type 2 patients. We concluded serum zinc significant lower in both diabetes group than healthy group, copper significant high in both diabetes group than healthy group, gender have significant effect in serum zinc and copper, weak positive correlation between zinc and HbA1C and weak negative correlation between copper and HbA1C. Conclusion: This study concluded that the serum levels of Zinc significant lower in type 2 diabetes than healthy individuals. Serum levels of Copper significant increase in type 2 diabetes than healthy individuals as have been found in present study. Gender have significant effect in serum Zn and Cu in diabetic patients. Weak Positive correlation between serum Zinc with HbA1c and weak negative correlation between copper with HbA1c.
