OBJECTIVE To observe the effects of liraglutide on cardiovascular metabolism, left ventricular structure and function of non-alcoholic fatty liver disease (NAFLD) patients with type 2 diabetes mellitus (T2DM). METHODS Totally 351 NAFLD patients with T2DM were enrolled retrospectively, who visited the Department of Endocrinology in our hospital from January 2019 to December 2022. They were divided into control group (196 cases) and observation group (155 cases) according to different treatment regimens. The control group received conventional standard treatment, and the observation group was additionally given Liraglutide injection 0.6 mg/d subcutaneously once a day based on the control group, adjusted to 1.2 mg/d after 7 days. Both groups received regular treatment for more than 12 months. The propensity matching method was used to match the two groups of patients at a ratio of 1∶1. The cardiovascular metabolism indexes and cardiac ultrasound parameters were compared, and the correlation between left ventricular structure, function parameters and cardiovascular metabolism indexes was analyzed. RESULTS After propensity score matching, there was no significant difference in baseline clinical data between the two groups (each 155 cases) before treatment (P>0.05). After 12 months of treatment, the waist circumference, weight, body mass index (BMI), systolic blood pressure (SBP), fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c) and triglyceride (TG) of both groups, as well as the diastolic blood pressure (DBP), total cholesterol (TC), uric acid (UA) and left ventricular mass (LVM) of the observation group, exhibited a significant decrease compared to pre-treatment levels (P<0.05). The high-density lipoprotein cholesterol (HDL-C), estimated glomerular filtration rate (eGFR), and E/A ratio in both groups, as well as the aspartate aminotransferase (AST) in the control group and the left ventricular ejection fraction (LVEF) in the observation group, were all significantly increased compared with before treatment in the same group (P<0.05). Moreover, the improvement of the above indicators (except for TG and SBP) in the observation group was generally more significant than those in the control group (P<0.05). The left ventricular structure and functional parameters (LVM, LVEF, E/A ratio) of the two groups before and after treatment had varying degrees of correlation with the patients’ waist circumference, body weight, BMI, SBP, FBG and HbA1c. Moreover, BMI (observation group: β= 0.229, P=0.004) and SBP (control group: β=0.240, P=0.004; observation group: β=0.226, P=0.007) were independent influential factors for LVM of the patients. CONCLUSIONS Liraglutide combined with conventional standard treatment can effectively control blood glucose in NAFLD patients with T2DM, reduce waist circumference, body weight and blood pressure, improve blood lipid disorders, and protect their cardiac structure and function.
Résumé
OBJECTIVES@#Patients with classical type 1 diabetes mellitus (T1DM) require lifelong dependence on exogenous insulin therapy due to pancreatic beta-cell destruction and absolute insulin deficiency. T1DM accounts for about 90% of children with diabetes in China, with a rapid increase in incidence and a younger-age trend. Epidemiological studies have shown that the overall glycated haemoglobin (HbA1c) and compliance rate are low in Chinese children with T1DM. Optimal glucose control is the key for diabetes treatment, and maintaining blood glucose within the target range can prevent or delay chronic vascular complications in patients with T1DM. Therefore, this study aims to investigate the glycemic control of children with T1DM from Hunan and Henan Province with flash glucose monitoring system (FGMS), and to explore factors associated with glycemic variability.@*METHODS@#A total of 215 children with T1DM under 14 years old were enrolled continuously in 16 hospitals from August 2017 to August 2020. All subjects wore a FGMS device to collect glucose data. Correlation of HbA1c, duration of diabetes, or glucose scan rates with glycemic variability was analyzed. Glucose variability was compared according to the duration of diabetes, HbA1c, glucose scan rates and insulin schema.@*RESULTS@#HbA1c and duration of diabetes were positively correlated with mean blood glucose, standard deviation of glucose, mean amplitude of glucose excursions (MAGE), and coefficient of variation (CV) of glucose (all P<0.01). The glucose scan rates during FGMS wearing was significantly positively correlated with time in range (TIR) (P=0.001) and negatively correlated with MAGE and mean duration of hypoglycemia (all P<0.01). Children with duration ≤1 year had lower time below range (TBR) and MAGE when compared with those with duration >1 year (all P<0.05). TIR and TBR in patients with HbA1c ≤7.5% were higher (TIR: 65% vs 45%, TBR: 5% vs 4%, P<0.05), MAGE was lower (7.0 mmol/L vs 9.4 mmol/L, P<0.001) than those in HbA1c >7.5% group. Compared to the multiple daily insulin injections group, TIR was higher (60% vs 52%, P=0.006), MAGE was lower (P=0.006) in the continuous subcutaneous insulin infusion group. HbA1c was lower in the high scan rates (≥14 times/d) group (7.4% vs 8.0%, P=0.046), TIR was significantly higher (58% vs 47%, P<0.001), and MAGE was lower (P<0.001) than those in the low scan rate (<14 times/d) group.@*CONCLUSIONS@#The overall glycemic control of T1DM patients under 14 years old in Hunan and Henan Province is under a high risk of hypoglycemia and great glycemic variability. Shorter duration of diabetes, targeted HbA1c, higher glucose scan rates, and CSII are associated with less glycemic variability.

The impairment of islets β cell by autoimmune response is an important cause of type 1 diabetes mellitus (T1DM). Some monogenic autoimmune syndromes could induce T1DM in difference chance, which are important disease models to deeply understand autoimmunity and T1DM. This article reviews the diagnosis, treatment and genetic detection of eight known single gene autoimmune syndromes associated with T1DM, arming to expand the diagnosis and treatment of T1DM.
Résumé
This study reported a family of mitochondrial diabetes mellitus complicated with chronic hereditary pancreatitis. A 18-year-old woman presented with self-reported hyperglycemia and chronic epigastric pain was admitted to our hospital. Clinical data and family history were collected. Mitochondrial gene sequencing and whole exon gene sequencing showed that the proband carried mutation of mt.3243A>G and heterozygous mutation of SPINK1 c. 194+ 2T>C, which was considered as mitochondrial diabetes mellitus with chronic pancreatitis.
Résumé
Objective This study was carried out to analyze the clinical characteristics of pseudohypopara-thyroidism(PHP) type 1b, and to improve the understanding and diagnosis of the disease. Methods Five patients with molecular diagnosis of pseudohypoparathyroidism type 1b in our hospital during 2018 were enrolled, their clinical data, biochemical indicators, imaging, and gene detection results were analyzed. Results There were 4 females and 1 male, with low calcium, high phosphorus and high PTH seran con centrations. The onset age span was large and the onset symptoms were different. Family history may not be obvious. There wer was abnormal methylation of GNAS gene or deletion of exon STX16 in methylation-specific multiplex ligation-dependent probe amplification ( MS-MLPA ) detection while gene sequeming result was negative. Conclusion MS-MLPA detection was still needed in patients with suspected PHP but negative gene sequencing result. Different methylation abnormalities and copy number variations might be correlated with the onset symptoms and familial of type 1b PHP.
