RESUMEN
BACKGROUND Sodium-glucose cotransporter 2 (SGLT2) inhibitors are used to improve the prognosis of patients with diabetes, heart failure, or chronic kidney disease. The use of SGLT2 inhibitors in patients without diabetes is expected to increase. Diabetic ketoacidosis is a severe complication of SGLT2 inhibitors in patients with diabetes. People without diabetes are thought to be less likely to develop ketoacidosis, and reports of SGLT2 inhibitor-induced ketoacidosis are uncommon in people without diabetes. CASE REPORT Herein, we describe a case of ketoacidosis in an 83-year-old Japanese woman without diabetes who was administered SGLT2 inhibitors for heart failure (ejection fraction: approximately 30%). Two weeks prior to admission, she had suffered a vertebral fracture and rib fracture due to a fall, which was followed by anorexia, but she continued to take SGLT2 inhibitors. On admission, blood test results revealed a blood glucose level of 124 mg/dL, hemoglobin A1C level of 5.9%, pH of 7.329, HCO3â» concentration of 14.3 mmol/L, and a ß-hydroxybutyrate concentration of 5150 µmol/L, leading to a diagnosis of euglycemic ketoacidosis. The patient's C-peptide level was consistent with the blood glucose levels on admission, indicating that she had adequate insulin secretion. The patient was treated only with glucose administration without insulin and was discharged after discontinuation of the SGLT2 inhibitor. CONCLUSIONS This case illustrates that patients with or without diabetes may develop SGLT2 inhibitor-related ketoacidosis after several days of inadequate food intake; therefore, patients should be informed of this risk.

AIMS/INTRODUCTION: Diabetes mellitus is reported as a risk factor for increased coronavirus disease 2019 (COVID-19) severity and mortality, but there have been few reports from Japan. Associations between diabetes mellitus and COVID-19 severity and mortality were investigated in a single Japanese hospital. MATERIALS AND METHODS: Patients aged ≥20 years admitted to Osaka City General Hospital for COVID-19 treatment between April 2020 and March 2021 were included in this retrospective, observational study. Multivariable logistic regression analysis was carried out to examine whether diabetes mellitus contributes to COVID-19-related death and severity. RESULTS: Of the 262 patients included, 108 (41.2%) required invasive ventilation, and 34 (13.0%) died in hospital. The diabetes group (n = 92) was significantly older, more obese, had longer hospital stays, more severe illness and higher mortality than the non-diabetes group (n = 170). On multivariable logistic regression analysis, age (odds ratio [OR] 1.054, 95% confidence interval [CI] 1.023-1.086), body mass index (OR 1.111, 95% CI 1.028-1.201), history of diabetes mellitus (OR 2.429, 95% CI 1.152-5.123), neutrophil count (OR 1.222, 95% CI 1.077-1.385), C-reactive protein (OR 1.096, 95% CI 1.030-1.166) and Krebs von den Lungen-6 (OR 1.002, 95% CI 1.000-1.003) were predictors for COVID-19 severity (R2 = 0.468). Meanwhile, age (OR 1.104, 95% CI 1.037-1.175) and Krebs von den Lungen-6 (OR 1.003, 95% CI 1.001-1.005) were predictors for COVID-19-related death (R2 = 0.475). CONCLUSIONS: Diabetes mellitus was a definite risk factor for COVID-19 severity in a single Japanese hospital treating moderately-to-severely ill patients.

We herein report a case of Addison's disease caused by tuberculosis characterized by atypical hyperpigmentation, noted as exacerbation of the pigmentation of freckles and the occurrence of new freckles, that was diagnosed in the presence of active pulmonary tuberculosis. The clinical condition of the patient was markedly ameliorated by the administration of hydrocortisone and anti-tuberculosis agents. When exacerbation of the pigmentation of the freckles and/or the occurrence of new freckles are noted, Addison's disease should be considered as part of the differential diagnosis. In addition, the presence of active tuberculosis needs to be assumed whenever we treat patients with Addison's disease caused by tuberculosis, despite its rarity.

We report a case of 71-year-old man who developed a hypersensitivity syndrome associated with terbinafine. He was placed on terbinafine (250 mg/d) for the treatment of tinea pedis due to diabetes mellitus. Following the treatment with terbinafine, he developed drug-induced hypersensitivity syndrome (DIHS). Systemic corticosteroid led to transient improvement of his clinical manifestations. Three months after disease onset, he presented with panperitonitis due to ileal perforation, and underwent an emergency operation. The affected ileum was resected and ileostomy was performed in the terminal ileum. Cytomegalovirus (CMV)-specific IgG antibodies were significantly increased, high-titer CMV antigenemia was detected, and pathological examination of the resected ileum confirmed CMV infection. Based on these observations, we strongly recommend that physicians monitor reactivation of the family of herpesvirus other than herpesvirus 6, to manage DIHS properly.

A 55-years-old man was admitted to our hospital with a 6-month history of general fatigue, purulent nasal discharge, polyuria, and polydipsia. Endocrinological findings revealed central diabetes insipidus (CDI) with mild anterior pituitary dysfunction. Imaging studies revealed thickening of the proximal end of the pituitary stalk just below the third ventricle, a mass in the paranasal sinus, and a mass encompassing the abdominal aorta. Histopathology of the mass in the paranasal sinus revealed abundant IgG4-positive plasma cells, and the IgG4 serum level was markedly elevated. Thus, he was diagnosed with IgG4-related multifocal fibrosclerosis. Therapy with prednisolone resulted in complete resolution of clinical symptoms and reduction in size of the masses in the affected organs. However, CDI remained unchanged. This is the first case in which the cause of CDI was IgG4-related multifocal fibrosclerosis. IgG4-related sclerosing disease should be included in the differential diagnosis of thickening of the pituitary stalk with CDI, and a search for extra-pituitary involvement is essential.

An 18-year-old man with 4-year history of central diabetes insipidus and partial pituitary dysfunction was admitted to our hospital because of headache and nasal discharge. Magnetic resonance imaging (MRI) revealed abnormal mass in the sella turnica invading into the cavernous sinus and sinus maxillaries along with thickened tentorium cerebelli. Histopathology of the mass in the sinus maxillaries revealed spindle-shaped cells arranged in a fascicular pattern with varied myxoid and collagenized regions with various inflammatory cells. Immunostaining revealed the spindle-shaped cells were positive for smooth muscle actin. These features were identical to those of inflammatory myofibroblastic tumor (IMT). He was diagnosed with IMT in the sella turnica and other regions. Corticosteroid therapy improved clinical symptoms and follow-up MRI revealed amelioration of the thickened tentorium cerebelli. However, the other lesions were unchanged and pituitary dysfunction did not improve. Although rare, IMT should be considered in the differential diagnosis of a sellar mass. Early treatment with corticosteroid therapy may reduce the risk of disease progression.

A 78-year-old woman was treated with 40 mg of prednisolone for microscopic polyangitis, and favorable effects were observed. However, her blood pressure increased and she developed severe thrombocytopenia. Thrombotic microangiopathy (TMA) due to malignant hypertension was suspected and she was treated with an angiotensin-converting enzyme inhibitor; her platelet count then rose. She showed a close temporal relationship between initiation of corticosteroid therapy and the onset of TMA. Corticosteroid therapy should be used with caution in patients with underlying vascular endothelial damage.
