Changes in body weight and composition, metabolic parameters, and quality of life in patients with type 2 diabetes treated with subcutaneous semaglutide in real-world clinical practice.

Subcutaneous once-weekly (ow) semaglutide is a recent treatment option for type 2 diabetes (T2D) and obesity, but real-world data on weight loss and associated changes in body composition, nutrients intake, and quality of life are still scarce. This observational, prospective clinical study involved all T2D patients starting ow semaglutide according to routine care between December 2021 and February 2022. Clinical information was collected after 6 months (T6) and 12 months (T12) from semaglutide initiation (T0). Bioelectrical Impedance Analysis (BIA) was performed to measure changes in body composition. Diabetes Treatment Satisfaction Questionnaire (DTSQ) and the 36 - items Short Form Health Survey (SF-36) were administered as patient-reported outcomes (PROs). Changes in continuous endpoints (weight, body composition, nutrients intake, other clinical parameters, and PROs) were assessed using mixed models for repeated measurements. Overall, 90 patients (age 63.0 ± 10.0 years; diabetes duration 7.6 ± 5.9 years; 58.9% men; HbA1c 7.7 ± 1.1%; weight 95.4 ± 19.4 Kg, BMI 34.6 ± 6.4 Kg/m2; 36.7% naïve to diabetes treatment, 43.3% on metformin, 10.0% on dual oral therapy, and 10.0% treated with schemes including insulin) were included in the study. After 6 months from semaglutide initiation, body weight significantly decrease by -4.69 Kg (95%CI -6.19;-3.19) (primary endpoint). After 12 months, body weight was further reduced (-5.38 Kg; 95%CI -7.79;-2.97). At BIA, fat mass was significantly reduced by 2.1 Kg after 6 months but only slightly reduced after 12 months vs. baseline; lean mass was also significantly reduced by over 3 Kg both at 6 and 12 months. Intake of all nutrients declined in the first 6 months of therapy, although only lipids reduction reached the statistical significance (-6.73 g; p=0.02). Statistically significant improvements in BMI, waist circumference, glycemic control, blood pressure and lipid profile were documented. Satisfaction with treatment (DTSQ questionnaire) and mental health (MCS score of SF-36 questionnaire) significantly increased during the follow-up. The study documented real-world benefits of semaglutide for treating obesity in T2D subjects, with important changes on clinical and patient-reported outcomes. Loss of lean mass associated with weight loss warrants attention; parallel strategies to preserve skeletal muscle and improve physical function, i.e. nutritional education and structured exercise, are of great importance.

Food knowledge of patients at the first access to a Diabetology center. / Conoscenze alimentari in pazienti afferenti ad un centro di diabetologia

Il diabete rappresenta una patologia in costante aumento: familiarità, età e stili di vita rappresentano i principali fattori di rischio per questa malattia e per le complicanze ad essa correlate. Considerando l'importanza del regime alimentare per la prevenzione e il trattamento di questa patologia, scopo del presente studio è stato quello di valutare le conoscenze alimentari di pazienti al primo accesso presso un centro di Diabetologia e di indagare sulla loro eventuale influenza su alcuni parametri ematici. È stato somministrato il questionario di Moynihan. La relazione tra i punteggi ottenuti e le variabili emoglobina glicata, BMI, glicemia a digiuno, è stata analizzata attraverso regressione multipla basata sul metodo dei minimi quadrati ordinari (modello OLS). Il response rate è stato del 73,3%. Il punteggio medio totale ottenuto dal questionario è stato di 23,61 ed è stata osservata una correlazione statisticamente significativa (p<0,0473) tra i migliori punteggi del questionario e i valori di Hb1Ac. Questo studio è il primo passo di un'indagine più ampia che verrà condotta nell'ottica di promuovere una formazione del paziente volta a verificare nel tempo le ricadute positive sulle scelte alimentari e sui parametri clinici.
