Abstract
INTRODUCTION: This study presents a 10-years longitudinal assessment of bone status in adolescents and young adults with type 1 diabetes (T1D). MATERIALS AND METHODS: Thirty two patients (12 female, aged 20.5±3.93 years, T1D duration 13.9±1.97 years) were studied using Quantitative Ultrasound (QUS) and Dual Energy X-ray Absorptiometry (DXA). Standard deviation scores (SDS) for these results were calculated. Following clinical parameters were analyzed: sex, age, T1D duration, anthropometric parameters, daily insulin requirement (DIR), mean of glycated hemoglobin (HbA1c) in the year preceding the examination, medication other than insulin, history of bone fractures and comorbidities. RESULTS: The current and past (measured 10 years earlier) QUS results did not differ and showed a significant correlation (r=0.55, p=0.001). We found no relation of QUS results and anthropometric parameters or gender. DXA parameters did not correlate with the present QUS measurement. DXA and QUS results were independent from HbA1c, co-morbidities or additional medicaments intake. CONCLUSIONS: Bone status parameters of the examined patients with currently suboptimal glycemic control were found to be lowered in comparison to normative reference population, both at baseline and follow-up, although no further deterioration was observed during the 10-year follow-up period.
