Nonalcoholic fatty liver disease (NAFLD) is a serious health-related condition all over the world; the number of patients is increasing in Asian countries including Japan. Better understanding of its pathophysiology is required to develop effective therapeutics, as patients may go on to develop non-alcoholic steatohepatitis and hepatocellular carcinomas. While NAFLD is believed to be associated with metabolic risk factors such as obesity, diabetes, and dyslipidemia, its etiology remains largely unknown and the development or co-existence of NAFLD in patients with insulinoma has not been investigated. A 33-year-old male with an insulinoma, who had been hypoglycemic during the previous four years, developed abnormally elevated levels of liver enzymes and histological fatty liver characteristic of NAFLD by the time of admission to our hospital for resection of an insulinoma. His medical records for the previous eight years revealed that his bodyweight had increased gradually from 60 kg to 71 kg for seven years and then acutely increased to 79 kg in the latest one-year period. This sudden increase was thought to be due to the patient’s self-described overeating of fruits to forestall hypoglycemia. Fresh fruits are rich in fructose, and the patient’s triglycerides, alanine and aspartate transaminases showed an acute increase in the previous one-year period. After resection of the insulinoma, the levels of these parameters all were mostly restored, which suggests that hyperinsulinemia and subsequent hyperphagia played a role in the development of NAFLD in this case. This is the first report of patient with NAFLD and an insulinoma.

Luseogliflozin, a selective sodium glucose cotransporter 2 inhibitor, was demonstrated in a previous 24-week study of type 2 diabetic patients to be efficacious and well tolerated. This study mainly aimed to evaluate the long-term safety of luseogliflozin monotherapy in Japanese type 2 diabetic patients based on the Japanese guidelines. Additionally, long-term efficacy was also evaluated. Patients on diet and exercise therapy alone with an HbA1c of 6.9-10.5% received luseogliflozin 2.5 mg once daily for 52 weeks. For patients with insufficient glycemic control, this dose was able to be increased to 5 mg at Week 24. Adverse events (AEs), clinical laboratory tests, vital signs and 12-lead electrocardiograms were used to assess safety. Efficacy endpoints consisted of changes in HbA1c, fasting plasma glucose (FPG), and body weight from baseline. Of 299 patients who received luseogliflozin, 279 completed the study. Most AEs were mild in severity with incidences of AEs and adverse drug reactions at 75.3% and 16.7%, respectively. Although hypoglycemia was observed in 7 patients (2.3%), no major hypoglycemic episodes occurred. The incidences of AEs of special interest, including pollakiuria, volume depletion and urinary tract/genital infections, were at acceptable levels. Luseogliflozin significantly lowered HbA1c (-0.50%, P< 0.001), FPG (-16.3 mg/dL, P< 0.001) and body weight (-2.68 kg, P< 0.001) at Week 52 compared to baseline. Up-titration to 5 mg further improved glycemic control. In this long-term study of Japanese type 2 diabetic patients, luseogliflozin monotherapy was well tolerated for 52 weeks and provided a sustained glycemic lowering effect and reduced body weight.
