BackgroundAlterations in serum levels of trace elements reported in type 2 diabetes mellitus (T2DM) have been linked with induction of T2DM and associated complications.ObjectivesTo assess serum levels of copper (Cu), zinc (Zn) and selenium (Se) in T2DM patients with adequate and poor glycemic control.Patients And MethodsThis study was performed at King Khalid University Hospital, Riyadh. A total of 100 consenting T2DM patients comprising of 50 patients with glycated hemoglobin (HbA1c) less than 6.5% and 50 patients with HbA1c more than 6.5% along with a group of 50 normal healthy individuals were included in the study. Serum levels of Cu, Zn and Se were measured by inductively coupled plasma-mass spectrometry (ICP-MS) instrument.ResultsAmong T2DM patients with HbA1c <6.5%, mean serum Cu levels (13.4+4.3µmol/L) were not different from the controls (14.5+1.92µmol/L) whereas Zn (9.9+2.7µmol/Lvs15+3.2µmol/L;p<0.0001) and Se levels (1+0.2µmol/Lvs1.62+0.2µmol/L; p<0.0004) were lower than the controls. Among T2DM patients with HbA1c >6.5% mean serum Cu (18.1+4.1µmol/Lvs14.5+1.9µmol/L; p<0.0001), Zn (15+3.2µmol/Lvs13.5+1.9µmol/L; p<0.009) and Se (1.62+0.2µmol/Lvs1.17+0.16µmol/L;p<0.0001) were significantly higher than the controls. HbA1c% negatively correlated with HbA1c >6.5% (r = -0.302; p<0.03).ConclusionCu, Zn and Se homeostasis was altered in T2DM patients and varied with glycemic control.© 2020 Hasanato RMW.
