Abstract

The hybrid closed-loop (HCL) system, Medtronic MiniMed 770G, has been available for use by Japanese individuals with type 1 diabetes mellitus since 2021. The aim of this study was to evaluate the effect of its use on glycemic variability and quality of life (QOL) in this population. This multicenter, open-label, prospective observational study included 14 Japanese individuals with type 1 diabetes mellitus treated with MiniMed 640G. Participants who switched to the 770G system were evaluated for time in range (TIR) and other glycemic outcomes at baseline and at 3 and 12 months post-transition. QOL was assessed using the Diabetes Therapy-Related QOL (DTR-QOL) scale. The mean baseline glycated hemoglobin was 7.52 ± 1.05%, and body mass index (BMI) was 21.78 ± 3.07 kg/m2. By study completion, individuals used the HCL system approximately 80% of the time in a day. TIR showed improvement, with an increased achievement ratio of TIR > 70% at 12 months. Hypoglycemia occurrence was minimal at 12 months. In addition, all-time sensor glucose measurements decreased after 12 months, and there were no significant changes in BMI or daily insulin dose. DTR-QOL scores did not significantly differ, possibly owing to increased total alarms and sensor calibration times. Transitioning to the Medtronic MiniMed 770G system led to an improved achievement ratio of TIR > 70% and reduced hyperglycemia at 12 months. However, no significant change in QOL was observed, probably because of the increased number of total alarms.

期刊介绍: Diabetology International, the official journal of the Japan Diabetes Society, publishes original research articles about experimental research and clinical studies in diabetes and related areas. The journal also presents editorials, reviews, commentaries, reports of expert committees, and case reports on any aspect of diabetes. Diabetology International welcomes submissions from researchers, clinicians, and health professionals throughout the world who are interested in research, treatment, and care of patients with diabetes. All manuscripts are peer-reviewed to assure that high-quality information in the field of diabetes is made available to readers. Manuscripts are reviewed with due respect for the author''s confidentiality. At the same time, reviewers also have rights to confidentiality, which are respected by the editors. The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
