Euglycemic diabetic ketoacidosis (eDKA) has emerged as an adverse event associated with sodium-glucose transporter-2 inhibitors (SGLT2i). We present two consecutive cases of SGLT2i-induced eDKA, both manifested as life-threatening coronary vasospastic angina (VSA). Case 1: A 64-year-old male overweight patient with type 2 diabetes (BMI 28.

Article Synopsis
  • A delayed large local reaction (DLLR) is a skin reaction that can occur after receiving the mRNA-1273 COVID-19 vaccine, prompting an investigation into its correlation with sex and age.
  • The study, conducted in Tokyo, involved 5893 participants who reported symptoms of DLLR after their first vaccine dose, with interviews led by dermatologists.
  • Results showed that 12.7% of participants experienced DLLR symptoms, with a notably higher incidence in females (22.4%) and younger age groups (specifically those aged 30-59), but symptoms were mild and not harmful.

Adipose tissue hypoxia is an important feature of pathological adipose tissue expansion. Hypoxia-inducible factor-1α (HIF-1α) in adipocytes reportedly induces oxidative stress and fibrosis, rather than neoangiogenesis via vascular endothelial growth factor (VEGF)-A. We previously reported that macrophages in crown-like structures (CLSs) are both hypoxic and inflammatory.

Chronic inflammation is a pathophysiology of insulin resistance in metabolic diseases, such as obesity and type 2 diabetes. Adipose tissue macrophages (ATMs) play important roles in this inflammatory process. SIRT1 is implicated in the regulation of glucose metabolism in some metabolic tissues, such as liver or skeletal muscle.

Sarcoidosis and systemic sclerosis (SSc) rarely coexist. Here, we report a Japanese female SSc patient who developed systemic sarcoidosis. Her SSc was a limited type negative for anti-Scl-70 antibody and positive for anticentromere antibody (ACA).

Localized scleroderma (morphea) usually develops spontaneously, but the precise mechanisms underlying disease development are obscure. However, a significant number of cases suggest that morphea is induced by external stimuli. Herein, we report a case of morphea that developed after a needle biopsy.

Diet-induced obesity is reported to induce a phenotypic switch in adipose tissue macrophages from an antiinflammatory M2 state to a proinflammatory M1 state. Telmisartan, an angiotensin II type 1 receptor blocker and a peroxisome proliferator-activated receptor-γ agonist, reportedly has more beneficial effects on insulin sensitivity than other angiotensin II type 1 receptor blockers. In this study, we studied the effects of telmisartan on the adipose tissue macrophage phenotype in high-fat-fed mice.

Nonalcoholic fatty liver disease (NAFLD) is an abnormal liver metabolism often observed with insulin resistance and metabolic syndrome. Calorie restriction is a useful treatment for NAFLD and reportedly prolongs the life spans of several species in which sirtuin plays an important role. In this study, we examined whether the activation of SIRT1, a mammalian ortholog of sirtuin, may ameliorate the development of NAFLD.

Monocyte chemoattractant protein-1 (MCP-1) and angiotensin II (Ang II) in adipose tissue are thought to induce systemic insulin resistance in rodents; but the precise mechanism is not fully clarified. We examined the mechanism of Ang II-induced and/or tumor necrosis factor-alpha (TNF-alpha)-induced MCP-1 production from 3T3-L1 preadipocytes. The MCP-1 protein and MCP-1 mRNA expression in 3T3-L1 preadipocytes were increased significantly by stimulation with TNF-alpha.

Telmisartan, a new angiotensin II type 1 receptor blocker (ARB), was recently reported to stimulate PPARgamma, and stronger effects of Telmisartan on insulin sensitivity has been expected than the class effect of ARB. In the present study, we examined the effects of Telmisartan on insulin sensitivity and adipokine levels in hypertensive and type 2 diabetic patients. Outpatients with both hypertension and type 2 diabetes mellitus (n=36; male 23, female 13), received 20-40mg Telmisartan orally once daily for 6 months.
