BACKGROUND AND OBJECTIVE: Lipodystrophy is a potential clinical complication induced by insulin therapy, and it is believed that its frequency has been reduced by using recombinant human insulin. Aim of this study was to determine the frequency of recombinant human insulin induced lipodystrophy in diabetic patients. MATERIALS AND METHODS: This cross sectional study was done on 220 diabetics referring to Imam Educational Hospital of Sari Township in 2007-2008 who had been under treatment with recombinant human insulin at least three months before. First, the anthropologic and clinical features of the patients were recorded in questionnaire, then all of the patients were examined clinically for lipodystrophy. In all patients, glycosylated hemoglobin (HbA1C) was measured for control of the blood glucose. The obtained data were analyzed by the descriptive statistical methods, t-test and 2 test. RESULTS: From the total 220 diabetics under study, 35 (15.9%) had insulin induced lipodystrophy, of them 32 (14.5%) had lipohypertrophy and 3 (1.4%) with lipoatrophy. Factors such as age, sex, level of education, body mass index (BMI), type of diabetes, period of using insulin and injection site had significant influence in development of insulin induced lipodystrophy (p<0.05). CONCLUSIONS: Findings of this study revealed that despite using a recombinant human insulin, the frequency of the lipodystrophy particularly of lipohypertrophy still remained high level. Therefore, a regular examination of the diabetic patients for this complication is necessary, specially in the individuals who have a defective control on their blood glucose level.
