SGLT2 inhibitors as potentially helpful drugs in PI3K inhibitor-induced diabetes: a case report.

Background: Hyperglycemia is the most common side-effect of phosphatidylinositol 3-kinase (PI3K) inhibitors that are approved for the treatment of some advanced or metastatic breast cancers. This side-effect is likely due to the central role of PI3K in insulin signalling. Here we report the use of a sodium-glucose cotransporter 2 (SGLT2) inhibitor to manage severe hyperglycemia.

Phenotypic expression of diabetes secondary to a T14709C mutation of mitochondrial DNA. Comparison with MIDD syndrome (A3243G mutation): a case report.

Objective: To analyze the clinical and biochemical features of a recently described point mutation of mitochondrial DNA associated with diabetes. This mutation, characterized by a T14709C transition of a highly conserved nucleotide in the region coding for the glutamic acid tRNA, is heteroplasmic.

Research Design And Methods: The phenotypic expression in the insulin-requiring diabetic proband from the pedigree was compared to that of diabetic probands from three families with the classic A3243G mtDNA mutation (maternally inherited diabetes and deafness [MIDD] syndrome).

[Corticotropic adenoma in slow adrenal insufficiency].

This case report deals with an insulin-dependent diabetic patient suffering peripheral adrenal insufficiency who, after 12 years of substitutive treatment exhibited resistance to mineralo- and gluco-corticoids with relapse of melanodermia and plasma ACTH levels higher than 1500 pg/ml despite increasing doses. A corticotrop macroadenoma was diagnosed by MR imaging and functional tests and confirmed by surgical excision followed by disappearance of resistance. Pre-operative functional investigation show autonomisation of the adenoma but with some partial persisting regulation.
