title: [Insulin transference in 198 patients from 6 Latin American countries].
abstract: A multicentric, comparative, single-blind, randomized, prospective study was designed to evaluate the efficacy and safety of the transference from animal source insulins to rDNA human insulin in Latinamerican insulin-requiring diabetic patients. All the patients were on animal insulin for at least two months before inclusion. The patients were evaluated at the beginning, and at two and six weeks after inclusion. A total 198 patients completed the study and were considered evaluable: 94 were assigned to the animal insulin group, and 104 to the human insulin group. There were no statistically significant baseline differences between groups. The only statistically significant difference, detected at the end of the study, was a reduction in fasting blood glucose level in the human insulin group (animal insulin 212 +/- 95.3 initial vs 193 +/- 78.3 mg/dL final, p = 0.18; human insulin 198 +/- 86.8 vs 169 +/- 71.7, p = 0.025). There were no statistically significant initial-final changes in the rest of the parameters evaluated although a trend of reduction in glycohemoglobin levels was observed in both groups. There were more episodes of mild hipoglycemia in the human insulin group, and only one episode of severe unwarned hypoglycemia in the same group. We conclude that the transference of insulins in Latinamerican diabetic patients is effective and reasonably safe (with a dose adjustment when the change is made).
