RESUMEN
Recently, the development of once-weekly incretin-based injections dulaglutide and semaglutide has drawn a great deal of attention. This study is aimed at comparing the efficacy of once-weekly GLP-1 receptor activator (GLP-1RA) dulaglutide and semaglutide on glycemic control and several metabolic parameters in patients with type 2 diabetes mellitus. We compared various clinical parameters between before and after switching from dulaglutide to semaglutide in "study 1" (pre-post comparison) and set the control group using propensity score matching method in "study 2." In "study 1," six months after the switching, HbA1c was significantly reduced from 8.2% to 7.6% and body mass index was also decreased from 30.4 kg/m2 to 30.0 kg/m2. Such effects were more pronounced in subjects whose glycemic control was poor. In "study 2," after 1 : 1 propensity score matching, glycemic control and body weight management were improved in the switching group compared with the dulaglutide continuation group. In this study including obese subjects with poor glycemic control, switching dulaglutide to semaglutide showed more beneficial effects on both glycemic and weight control irrespective of age, body weight, and diabetes duration. Therefore, we should bear in mind that it would be better to start using a relatively new once-weekly GLP-1RA semaglutide in clinical practice, especially in obese subjects with poor glycemic control with other GLP-1RAs.

BACKGROUND AND AIMS: Recently, pemafibrate, a selective PPARα modulator, has been developed as a treatment for hypertriglyceridemia and has attracted much attention. The aims of this study were to evaluate the efficacy and safety of pemafibrate in hypertriglyceridemia patients under clinical settings. METHODS AND RESULTS: We evaluated changes in lipid profiles and various parameters before and after 24-week pemafibrate administration in patients with hypertriglyceridemia who had not previously taken fibrate medications. There were 79 cases included in the analysis. 24 weeks after the treatment with pemafibrate, TG was significantly reduced from 312 ± 226 to 167 ± 94 mg/dL. In addition, lipoprotein fractionation tests using PAGE method showed a significant decrease in the ratio of VLDL and remnant fractionations, which are TG-rich lipoproteins. After pemafibrate administration, body weight, HbA1c, eGFR, and CK levels were not changed, but liver injury indices such as ALT, AST, and γ-GTP were significantly improved. CONCLUSION: In this study, pemafibrate improved the metabolism of atherosclerosis-induced lipoproteins in hypertriglyceridemia patients. In addition, it showed no off-target effects such as hepatic and renal damage or rhabdomyolysis.

Decreased pancreatic volume, increased pancreatic fat mass, and serrated pancreatic margins are characteristic morphological changes of the pancreas in subjects with type 2 diabetes mellitus. This retrospective study aimed to clarify the clinical significance of pancreatic morphological changes in subjects with type 2 diabetes mellitus who underwent abdominal magnetic resonance imaging. The mean age and HbA1c value were 59.1 ± 16.3 years old and 8.9 ± 2.3%, respectively. Pancreatic body mass corrected for body surface area (BSA) in subjects with diabetes mellitus was lower compared to those in normal glucose tolerance (49.4 ± 15.3 cm3 vs. 60.9 ± 7.8 cm3), although it did not reach a statistic significance. There was a negative correlation between BSA-corrected pancreatic volume and age, duration of diabetes, glycoalbumin, mean and max IMT, and there was a positive correlation between BSA-corrected pancreatic volume and HOMA2-ß. Serration of the pancreatic limbus was more often observed in subjects with diabetes mellitus compared to those in normal glucose tolerance (74.1% vs. 14.3%). Subjects with serrated changes were older and had higher HbA1c, and visceral fat area was significantly larger in subjects with serrated changes. BSA-corrected pancreatic volume in subjects with serrated changes was significantly smaller, and mean IMT was significantly thicker in subjects with serrulation. Furthermore, advanced diabetic retinopathy and diabetic nephropathy were more often observed in subjects with serrated changes. Taken together, decreased BSA-corrected pancreatic volume and serrated changes were associated with the progression of vascular complications in subjects with type 2 diabetes mellitus.

BACKGROUND: In subjects with hypothyroidism, edema is often observed, and pleural effusion and pericardial fluid could be also observed. The color of such fluid retention is usually yellow. Here we show a very rare case with hypothyroidism who had bloody pleural effusion and bloody pericardial fluid. CASE PRESENTATION: A 42-year-old male noticed chest pain and the aggravation of exertional dyspnea, and he was transported to our institution by emergency. He had Graves' disease and underwent total thyroidectomy about 4 years before. After then, he had been treated with 200 µg/day of levothyroxine sodium for the maintenance of thyroid function. However, he self-interrupted such medication about 2 years before. Thyroid function on admission was reduced as follows: free triiodothyronine, 1.60 pg/mL; free thyroxine < 0.40 ng/dL; thyroid-stimulating hormone 25.50 µU/mL. Inflammation markers were increased: white blood cells 25,280 /µL; C-reactive protein 18.66 mg/dL. A large amount of pericardial fluid and pleural effusion were observed in chest and abdominal computer tomography and echocardiography. In addition, we performed pleural effusion and pericardial fluid collection. Pleural effusion in this subject showed bloody color, but not yellow. In cell block specimen of pleural effusion and pericardial fluid, red blood cells, neutrophils and lymphocyte component were observed. In this subject, however, we were unable to find any obvious background disease causing bloody pericardial effusion. Finally, we concluded that bloody pleural effusion and bloody pericardial fluid were brought about in a subject with untreated known hypothyroidism after total thyroidectomy, triggered by pneumonia. CONCLUSIONS: In subjects with hypothyroidism, fluid and mucopolysaccharide are stored in interstitial space and protein osmolality is increased, thus leading to edema and fluid retention. It is noted here that pleural effusion and pericardial fluid in this subject showed bloody color and included red blood cells. There are no reports of bloody pericardial fluid with hypothyroidism. Therefore, it is important to keep in mind that a subject with some trigger, such as infection, may have a hematologic fluid retention that is not seen when hypothyroidism is present alone, as observed in this subject.

There are many tests for evaluating endogenous insulin secretory capacity. However, there are only a limited number of studies that have examined in detail in clinical practice which method most accurately reflects the ability to secrete endogenous insulin especially in hyperglycemic state. The purpose of this study was to find the endogenous insulin secretory capacity and a possible predictor of insulin withdrawal in subjects with type 2 diabetes requiring hospitalization due to hyperglycemia. In the endogenous insulin secretory test during hospitalization, CPR, CPR index, and ΔCPR after glucagon loading were all significantly higher in the insulin withdrawal group. On the other hand, there were no difference in fasting CPR index, HOMA-ß, SUIT, and 24-hour urinary CPR excretion between the two groups. In the glucagon test of the insulin withdrawal group, the cutoff value of ΔCPR was 1.0 ng/mL, the withdrawal rate of ΔCPR of 1.0 ng/mL or more was 69.2%, and the withdrawal rate of less than 1.0 ng/mL was 25.0%. In conclusion, it is likely that glucagon test is the most powerful tool for predicting the possibility of insulin withdrawal as well as for evaluating endogenous insulin secretory capacity in subjects with type 2 diabetes requiring hospitalization due to hyperglycemia.

Non-thyroidal illness (NTI) is a condition in which the hypothalamic-pituitary-thyroid system and thyroid hormone metabolism are abnormal due to non-thyroidal diseases. Although NTI has been reported to occur in hyperglycemic emergencies in children, there have been few studies in adult cases. In this study, we examined adult patients with hyperglycemia regarding the frequency of NTI and its triggers. Adult diabetic patients who were hospitalized for diabetic ketosis (DK), diabetic ketoacidosis (DKA), or hyperglycemic hyperosmolarity syndrome (HHS) were included in the study. Compared with the DK group, the DKA and HHS groups had higher admission blood glucose, Anion Gap, serum osmolality, creatinine, and urea nitrogen, and lower pH and eGFR. The frequency of NTI in the DKA, HHS, and DK groups was 80%, 70%, and 50%, respectively, and thyroid stimulating hormone (TSH) and free thyroxine 3 (FT3) were significantly improved after treatment for hyperglycemia. Multiple regression analysis showed a significant correlation between the decrease in FT3 level and 3-hydroxybutyrate and albumin. Acute metabolic failure associated with hyperglycemia tends to be associated with a high rate of NTI and low FT3 levels at the start of treatment. The data in this study clearly shows that transient NTI is frequently observed in subjects with acute metabolic disorders such as DKA, HHS and DK. In addition, we should bear in mind that thyroid hormone replacement therapy is not necessary in subjects with NTI due to DKA, HHS and DK, especially when overt symptoms of hypothyroidism are not observed.

AIMS/INTRODUCTION: This study examined the effect of daily walking steps on glycated hemoglobin, body mass index (BMI) and body composition while taking into consideration sedentary time (ST) in Japanese type 2 diabetes patients over a period of 12 months. MATERIALS AND METHODS: Self-administered ST values and information regarding daily walking steps were obtained and analyzed for 236 patients with type 2 diabetes who regularly visited the outpatient clinic. The patients - divided into three categories of daily walking steps: non-step counter user, <7,500 daily walking steps and ≥7,500 daily walking steps (HS) - were prospectively observed considering ST through the monitoring of glycated hemoglobin, BMI waist circumference (WC) and visceral fat accumulation (VFA) for 12 months. RESULTS: After 12 months, the participants categorized as the HS group had significantly reduced BMI and VFA independent of ST, as well as significantly reduced WC with high ST. WC and VFA disparities widened significantly at 12 months between the participants categorized as being in the non-step counter user group and the HS group with long ST. However, no difference in glycated hemoglobin levels and BMI were found among the three categories independent of ST. Compared with non-step counter users, the odds ratios with logistic regression models of improvement in BMI and VFA in the <7,500 daily walking steps and HS groups, and WC in the HS group after 12 months were significantly higher only among those with long ST. CONCLUSIONS: These results suggest that consideration of sedentary behavior in combination with daily walking steps might be essential for type 2 diabetes management.
