Objective:
To ascertain zinc deficiency in patients with insulin-dependent diabetes mellitus (IDDM) and evaluate the relationship between zinc clearance and body height velocity.
Research Design And Methods:
Six boys and 11 girls with IDDM and zincuria and glycosuria were studied. Study quality and specific descriptive information concerning relationship and outcome measurement were assessed.
Results:
The values of total-body zinc clearance in IDDM patients were higher than in the control subjects (24.6 +/- 1.8 vs. 15.1 +/- 0.6 ml.kg-1.h-1, P less than 0.01). There was a negative correlation between body zinc clearance values and height velocity in IDDM patients.
Conclusions:
Patients with IDDM have a secondary zinc deficiency, and normal growth may be stunted.
