PubMedID: 22783884 Background: The aim of this study was to compare the chromium levels of plasma (PCL), erythrocyte (ECL) and urine (UCL) in type 1 diabetics and healthy subjects and to review the relation between metabolic parameters. Methods: We evaluated 165 subjects who were: newly diagnosed type 1 diabetics (group 1 [n = 29]); previously diagnosed type 1 diabetics (group 2 [n = 18]); non-diabetic control subjects who were admitted and treated for any reason in hospital (group 3 [n = 21]); and two other groups of control subjects from two schools that have different socioeconomic levels (group 4 [n = 48] and group 5 [n = 49]). Results: PCL in group 1 and group 2 subjects (7.21 1 4.78 and 10.94 1 3.04 mcg/L, respectively) was significantly lower than in all control groups (21.84 1 7.87, 16.11 1 7.44, 17.25 1 8.58 mcg/L, respectively) (P < 0.05). A significant difference in PCL between the group 1 and group 2 subjects was present (7.21 1 4.78 and 10.94 1 3.04, respectively) (P = 0.021). ECL (as tissue chromium) in group 1 and group 2 subjects (13.99 1 11.37 and 19.64 1 12.58, respectively) was significantly lower than in all control groups (28.20 1 7.34.25, 49 1 12.47, 26.37 1 9.77 mcg/L, respectively) (P = 0.05). UCL in group 1 and group 2 subjects (11.44 1 6.88 and 15.68 1 6.75 mcg/L, respectively) was significantly lower than in group 3 subjects (28.83 1 9.37mcg/L) (P < 0.05). There were significant correlations between length, bodyweight and PCL in the group 1 subjects (r = 0.42, P = 0.22 and r = 0.53, P = 0.03, respectively). There was a negative correlation between plasma glucose and UCL, which was not statistically significant in group 2 subjects (r = -0.4, P = 0.061). Conclusion: There was a negative chromium balance in type 1 diabetics. This negative balance may affect the insulin function badly. If this negative balance should be confirmed by recent studies we suggest that chromium supplementation with insulin is necessary for type 1 diabetes. © 2012 The Authors. |
