Case of new-onset fulminant type 1 diabetes mellitus accompanied by autoimmune thyroid disease after SARS-CoV-2 infection.

There is growing evidence suggesting an association between severe acute respiratory coronavirus syndrome coronavirus 2 (SARS-CoV-2) infection and various extrapulmonary diseases since the advent of coronavirus disease 2019 (COVID-19) pandemic. However, case reports of fulminant type 1 diabetes mellitus (FT1D) following SARS-CoV-2 infection are limited. We encountered a 44-year-old Japanese woman who developed FT1D accompanied by subclinical thyrotoxicosis caused by autoimmune thyroid disease (AITD) approximately one week after SARS-CoV-2 infection.

Combined pituitary hormone deficiency harboring CHD7 gene missense mutation without CHARGE syndrome: a case report.

Background: Heterozygous loss-of-function mutations in the chromodomain helicase DNA-binding protein 7 (CHD7) gene cause CHARGE syndrome characterized by various congenital anomalies. A majority of patients with CHARGE syndrome present with congenital hypogonadotropic hypogonadism (HH), and combined pituitary hormone deficiency (CPHD) can also be present. Whereas CHD7 mutations have been identified in some patients with isolated HH without a diagnosis of CHARGE syndrome, it remains unclear whether CHD7 mutations can be identified in patients with CPHD who do not fulfill the criteria for CHARGE syndrome.

Exogenous insulin antibody syndrome in a patient with diabetes secondary to total pancreatectomy.

Exogenous insulin can induce insulin antibodies that have a low affinity/high binding capacity. Similar to what is observed in insulin autoimmune syndrome, these insulin antibodies can cause fasting hypoglycemia and postprandial hyperglycemia, a phenomenon known as "exogenous insulin antibody syndrome" (EIAS). Cases of EIAS in patients with type 1 and type 2 diabetes have been sporadically reported, mainly in Asia.

Endocrinological Features of Hartsfield Syndrome in an Adult Patient With a Novel Mutation of .

Hartsfield syndrome (HS: OMIM 615465) is a rare congenital disease associated with a mutation of the gene () with the main features of holoprosencephaly and ectrodactyly. Patients with HS also present with endocrinological deficits, such as isolated hypogonadotropic hypogonadism and central diabetes insipidus. Although there are several studies on infancy/childhood history, there is no study of infant/childhood/adolescent/young adult HS natural history and endocrinological findings.

Effects of alogliptin on the ratio of glycated albumin to HbA1c in patients with type 2 diabetes mellitus.

The ratio of glycated albumin (GA) to HbA1c (the GA/HbA1c ratio) has been used as a glycemic control indicator that reflects postprandial plasma glucose levels or glycemic variability. In this study, we investigated the effects of alogliptin, a DPP-4 inhibitor, on the GA/HbA1c ratio in patients with type 2 diabetes mellitus. Thirty-eight patients with type 2 diabetes mellitus whose glycemic control was stable were enrolled, and alogliptin (12.
