Abstract:
Background: Limited studies have been carried out with prednisone (PRED) in treatment by
glucose intolerant individuals, even in this model the animals presented low blood glucose levels at
adulthood, by the high regenerative capacity of β-cell.
Objective: The aim was to evaluate the effects of the treatment of PRED in mild diabetes on biochemical
and immunological biomarkers.
Methods: Rats were randomly divided into four groups: control (C), treated control C+PRED (treatment
of 1.25 mg/Kg/day PRED); diabetic DM (mild diabetes) and treated diabetic DM+PRED (treatment
with same dose as C+PRED group). Untreated groups received vehicle, adjusted volume to body
weight. The treatment lasted 21 days and measured body weight, food and water intake, and glycemia
weekly. In the 3rd week, the Oral Glucose Tolerance Test (OGTT) and the Insulin Tolerance Test (ITT)
was performed. On the last day, the rats were killed and the blood was collected for biochemical analyzes,
leukogram and immunoglobulin G levels.
Results: There was a significant decrease in body weight in mild diabetes; however, the treatment in
diabetic groups increased food intake, glycemia, and the number of total leukocytes, lymphocytes and
neutrophils. On the other hand, it decreased the levels of triglycerides, high-density and very lowdensity
lipoproteins. In addition, diabetic groups showed glucose intolerance and mild insulin resistance,
confirming that this model induces glucose intolerant in adult life.
Conclusion: The results showed that the use of prednisone is not recommended for glucose intolerant
individuals and should be replaced in order to not to aggravate this condition.
