RÉSUMÉ
Introduction Imeglimin is a novel oral antihyperglycaemic drug used to treat type 2 diabetes mellitus (T2DM). In 2022, its clinical use was approved in Japan; however, there is limited data on its practical efficacy. Thus, we retrospectively investigated the clinical efficacy of imeglimin for six months at the National Defense Medical College, Tokorozawa, Japan. Material and methods We conducted a single-center retrospective analysis to elucidate the efficacy of imeglimin in the treatment of T2DM. Ten patients were enrolled, and their biomarkers and geographic data were analyzed. The primary endpoint was the change in HbA1c level at six months after imeglimin treatment compared to the baseline values. Other demographic and laboratory parameters, including sex, age, BMI, renal function, liver function, lipid profile, and transient elastography data, were also analyzed. Results A significant improvement in the HbA1c levels (8.1 % at baseline to 6.9 % at six months after treatment, P value = 0.01) was observed in this study, suggesting that imeglimin is a promising option for treating T2DM. In addition, no negative effects on renal function were observed, and albumin levels tended to decrease from baseline values. Among the nonalcoholic fatty liver disease (NAFLD) cases, liver conditions, especially fat content, tended to improve in this short-term period. Conclusions Imeglimin is suggested to have a beneficial effect not only on glycemic control but also on renal and liver function. However, further studies are required to better understand the long-term efficacy of this drug.
RÉSUMÉ
RATIONALE: Although patients with central disorders of hypersomnolence (CDH) exhibit characteristic symptoms of hypersomnia frequently, it takes 5 to 15 years from the onset for its diagnosis due to the lack of symptom recognition. Here, we present a case of idiopathic hypersomnia (IH), a CDH, wherein early diagnosis was aided by a video footage of a spontaneous sleep attack. PATIENT CONCERNS: A 21-year-old man lost consciousness while driving and experienced an accident. He had complained of excessive daytime sleepiness (EDS) over half a year. During his hospitalization for close monitoring of the loss of consciousness, an in-room surveillance camera captured a 14-minutes long spontaneous sleep attack, during which he experienced general muscle weakness and loss of consciousness without warnings or convulsions leading to a fall from the bed. There were no abnormalities in vital signs. DIAGNOSES: There was no significant cataplexy and less than 2 sleep-onset rapid eye movements (SOREM) in 2 sleep latency tests, with a mean sleep latency of 2.1 and 4.6 minutes. Other sleep deprivation syndromes were excluded from differential diagnosis and finally, a diagnosis of IH was confirmed according to the criteria of the Third Edition of the International Classification of Sleep Disorders. During the course of the disease, attention-deficit/hyperactive disorder (ADHD) and a gaming disorder also diagnosed. INTERVENTIONS: Pharmacological treatment with modafinil was administered for IH and methylphenidate for ADHD. Cognitive behavioral therapy was performed for the gaming disorder. OUTCOMES: The EDS improved, and sleep attacks were no longer observed. The disruption of daily life caused by the gaming disorder was also reduced. LESSONS: Video recordings of sleep attacks are beneficial for identifying the cause of loss of consciousness. Home video recordings may be helpful in the early diagnosis of IH.
