| Sumario: | Santosh Nagaraju, Richard S Mangus, Tyra A Salisbury, Weston J Bush, Jason P Davis, John A Powelson, Jonathan A Fridell Department of Surgery, Indiana University School of Medicine, Indianapolis, IN, USACorrespondence: Richard S Mangus Email rmangus@iupui.eduAbstract: Type 1 diabetes (DM1) is associated with loss of skeletal muscle and bone mass and may affect body fat stores. This study employs computed tomography (CT) scans to assess the body composition of DM1 patients referred for pancreas transplant compared to healthy controls. A 1:1 case–control design matched study patients with otherwise healthy patients from the trauma database. Matching criteria included age ± 5 years, gender, and body mass index (BMI) ± 2kg/m2. Nutrition variables included serum albumin and protein levels, BMI, and CT measures of muscle mass and fat stores. There were 22 subjects and 22 controls (median DM1 duration 24 years). DM1 patients had less muscle mass and less subcutaneous fat but no difference in visceral fat. Patients with the greatest muscle deficit were those with DM1 greater than 20 years and those younger than age 40. DM1 patients maintain similar BMI and protein levels compared to healthy controls but have marked deficits of muscle and subcutaneous fat. These results inform the nutritional management of DM1 patients and quantify the muscle and fat deficits present in these patients. At highest risk are young patients and those with duration of DM1 over 20 years.Keywords: computed tomography, sarcopenia, sarcopenic obesity, nutrition, type 1 diabetes |
