Luseogliflozin improves liver fat deposition compared to metformin in type 2 diabetes patients with non‐alcoholic fatty liver disease: A prospective randomized controlled pilot study

This study aimed to assess the effect of luseogliflozin on liver fat deposition and compare luseogliflozin to metformin in type 2 diabetes (T2D) patients with non‐alcoholic fatty liver disease (NAFLD). Thirty‐two T2D patients with NAFLD diagnosed by computed tomography or abdominal sonography were recruited. Participants were randomly assigned to receive either luseogliflozin (2.5 mg, newly administered) or metformin (1500 mg, newly or additionally administrated). Data on the liver‐to‐spleen attenuation ratio (L/S), visceral fat area, body mass index, glycated hemoglobin (HbA1c), alanine aminotransferase (ALT), fasting plasma glucose, C‐peptide immunoreactivity (CPR), and CPR index were collected at baseline and after 6 months. The change in L/S was significantly greater in the luseogliflozin group than in the metformin group. Similarly, the changes in the visceral fat area, HbA1c, and body mass index were significantly greater in the luseogliflozin group than in the metformin group. The changes in ALT, fasting glucose, CPR, and CPR index were not significant in both groups. In conclusion, luseogliflozin significantly reduced liver fat deposition as compared to metformin, which may indicate clinical relevant benefits for NAFLD.

Hypoglycemia and glycemic variability are associated with mortality in non-intensive care unit hospitalized infectious disease patients with diabetes mellitus.

We aimed to identify factors – glycemic control, reactive inflammatory biomarkers or vital signs – associated with mortality in diabetic patients admitted to hospital for various infections (non‐intensive care unit).

Evaluation of safety of insulin degludec on undergoing total colonoscopy using continuous glucose monitoring

There is little information regarding how to use insulin degludec (D) when diabetic patients are preparing for total colonoscopy (TCS).

Investigating the Relationship between Morning Glycemic Variability and Patient Characteristics Using Continuous Glucose Monitoring Data in Patients with Type 2 Diabetes

Objective To investigate the relationship between patient characteristics and morning glycemic variability. Methods We retrospectively evaluated 106 patients with type 2 diabetes who underwent continuous glucose monitoring during admission. The highest postprandial glucose level (within 3 hours after breakfast; ‘highest level’), the time from the start of breakfast to the highest postprandial glucose level (‘highest time’), the difference between the pre-breakfast and highest postprandial breakfast glucose level (‘increase’), the area under the curve (AUC; ≥180 mg/dL) for the glycemic variability within 3 hours after breakfast (‘morning AUC’), and the post-breakfast glucose gradient (‘gradient’) were calculated. We analyzed the associations between these factors and nocturnal hypoglycemia and the patients’ characteristics by using a regression analysis. Results After stepwise multivariate adjustment, significant independent associations were found between ‘highest level’ and high age, low BMI, and high HbA1c; ‘highest time’ and high HbA1c, low C-peptide immunoreactivity (CPR), and low fasting plasma glucose (FPG); the ‘increase’ and high age, low BMI, high HbA1c, low FPG and hypoglycemia; ‘morning AUC’ and high age, high HbA1c and hypoglycemia; and ‘gradient’ and long duration of diabetes and low BMI. Conclusion Higher age and lower BMI are associated with higher ‘highest’ and ‘increase’ levels. Higher HbA1c levels were linked to a longer ‘highest time’, and longer durations of the diabetes, while lower BMI values were related to a higher ‘gradient’.

Glomerulonephritis Caused by CV Catheter-related Blood Stream Infection

A 45-year-old woman under home parenteral nutrition was admitted with recurrent fever and a worsening renal function. A diagnosis of central venous catheter-related blood stream infection (CVCRBSI) was made according to the identification of coagulase-negative Staphylococcus from both the peripheral blood and the removed CV catheter, along with an improvement of the symptoms following the removal of the catheter. Renal impairment with hypocomplementemia was thought to be secondary to the immune complex formation and deposition in the kidneys in response to prolonged bacteremia. This was confirmed by the pathological findings. Clinicians should therefore be aware that glomerulonephritis may be induced by long-term CVCRBSI.

l-Menthol sprayed on gastric mucosa causes edematous change.

Background and study aims: l-Menthol (LM), sprayed on the distal gastric mucosa, is a safe antispasmodic agent used during esophagogastroduodenoscopy (EGD). However, it seems to affect gastric mucosal endoscopic findings. Therefore, we evaluated whether LM causes specific changes and impacts the endoscopic morphology of gastric lesions. Patients and methods: A total of 98 patients scheduled to undergo EGD were randomly assigned to receive LM solution (160 mg of 0.8 % LM added to 2.5 mL of indigo carmine [IC]; n = 49; LM group) or decuple-diluted IC solution without LM (n = 49; placebo group). We compared the incidence of specific mucosal changes and the difference in the endoscopic findings of several gastric lesions between these groups. Results: Annular-reticular – like mucosal changes appeared immediately after the administration of LM solution. This change was observed in 71.4 % of the LM group compared with 12.2 % of the placebo group (P < 0.01). In the placebo group, this change was observed in 14.7 % of subjects with atrophic gastritis compared with 6.7 % of those without atrophic gastritis (P = 0.39), whereas in the LM group, this change was observed in 84.8 % of subjects with atrophic gastritis compared with 43.8 % of those without atrophic gastritis (P < 0.01). Most early gastric cancers, erosions, and ulcers observed in this study became well demarcated after LM administration, although the incidence of gastric lesions did not differ significantly between the two groups. Conclusion: LM changes the gastric mucosa into edematous mucosa, and this occurs more frequently in atrophic gastric mucosa than in pathologic lesions. LM may facilitate the demarcation of pathologic gastric lesions without intestinal metaplasia.

Development of an external-to-internal convertible endoscopic biliary drainage device – a preliminary prospective feasibility study

Background and study aims  Endoscopic nasobiliary drainage (ENBD) for a malignant stricture in the bile duct has some advantages over endoscopic biliary stenting (EBS). However, ENBD may cause nasopharyngeal discomfort. We developed an external-to-internal convertible endoscopic biliary drainage (ETI-EBD) device that enables both internal and external drainage to occur during a single endoscopy. Patients and methods  This device consists of three parts, comprising a 5-Fr ENBD tube (250 cm) (ENBD-t), an 8.5-Fr EBS tube (7 cm) (EBS-t), and an 8-Fr pusher tube for EBS (230 cm) (P-t). The EBS-t is mounted over the ENBD-t at the distal end of the ENBD-t. The P-t is also placed over the ENBD-t. After an endoscopic sphincterotomy, the EBS-t of the device is inserted into the papilla, then the duodenal endoscope is withdrawn, leaving the device in place. After ENBD, only the ENBD-t was withdrawn from the P-t. At this point, the EBS-t was isolated and left without endoscopy or radiography. Results  ETI-EBD was successfully placed in all consecutive 21 patients (100 %). The release of EBS-t from ENBD-t wit was successfully completed in 19 patients (90.5 %). There were 4 patients with kink of P-t when exchanging this device from the mouth to the nose. It was difficult for 2 patients to withdraw the ENBD-t because of poor lubrication performance. There were no significant complications associated with the use of the device. Conclusion  This device allows for both external and internal biliary drainage with a single endoscopy.
