SOCIETY FOR ENDOCRINOLOGY CLINICAL GUIDANCE: Inpatient management of cranial diabetes insipidus.

Endocr Connect 2018 Jul;7(7):G8-G11

Department of EndocrinologyOxford Centre for Diabetes, Endocrinology & Metabolism, Oxford, UK.

Cranial diabetes insipidus (CDI) is a treatable chronic condition that can potentially develop into a life-threatening medical emergency. CDI is due to the relative or absolute lack of the posterior pituitary hormone vasopressin (AVP), also known as anti-diuretic hormone. AVP deficiency results in uncontrolled diuresis. Read More

Transient diabetes insipidus in a post-partum woman with pre-eclampsia associated with residual placental vasopressinase activity.

Endocrinol Diabetes Metab Case Rep 2018 21;2018. Epub 2018 May 21.

Department of Endocrinology and Diabetes, Royal North Shore Hospital, Sydney, and University of Sydney, Sydney, Australia.

This case illustrates the exceedingly rare phenomenon of transient diabetes insipidus, in association with pre-eclampsia, occurring in the post-partum period following an fertilisation pregnancy, in an otherwise well 48-year-old lady. Diabetes insipidus can manifest during pregnancy, induced by increased vasopressinase activity secreted by placental trophoblasts and usually manifests in the third trimester. This presentation elucidates not only the intricate balance between the physiology of pregnancy and hormonal homeostasis, but also the importance of post-partum care as the physiological changes of pregnancy still hold pathological potential in the weeks immediately following delivery.

Genetic and clinical aspects of Wolfram syndrome 1, a severe neurodegenerative disease.

Pediatr Res 2018 May 28;83(5):921-929. Epub 2018 Feb 28.

Department of Pediatrics, University Hospital, Messina, Italy.

Wolfram syndrome 1 (WS1) is a rare autosomal recessive neurodegenerative disease characterized by diabetes insipidus, diabetes mellitus, optic atrophy, deafness, and other abnormalities. WS1 usually results in death before the age of 50 years. The pathogenesis of WS1 is ascribed to mutations of human WFS1 gene on chromosome 4p encoding a transmembrane protein called wolframin which has physiological functions in membrane trafficking, secretion, processing, and/or regulation of ER calcium homeostasis.

Division of Pulmonary, Critical Care, and Sleep Medicine, New York University School of Medicine, 462 First Avenue, NBV 7N24, New York, NY, 10016, USA.

Desmopressin, a synthetic vasopressin analog, is used to treat central diabetes insipidus, hemostatic disorders such as von Willebrand's disease, and nocturnal enuresis.

One too many diabetes: the combination of hyperglycaemic hyperosmolar state and central diabetes insipidus.

Endocrinol Diabetes Metab Case Rep 2018 11;2018. Epub 2018 Apr 11.

Department of Intensive Care Medicine, Lucerne Cantonal Hospital, Lucerne, Switzerland.

The combination of hyperosmolar hyperglycaemic state and central diabetes insipidus is unusual and poses unique diagnostic and therapeutic challenges for clinicians. In a patient with diabetes mellitus presenting with polyuria and polydipsia, poor glycaemic control is usually the first aetiology that is considered, and achieving glycaemic control remains the first course of action. However, severe hypernatraemia, hyperglycaemia and discordance between urine-specific gravity and urine osmolality suggest concurrent symptomatic diabetes insipidus. Read More

Chronic lithium treatment induces novel patterns of pendrin localization and expression.

Am J Physiol Renal Physiol 2018 Apr 18. Epub 2018 Apr 18.

Department of Medicine - Renal Division, Emory University School of Medicine, United States.

Prolonged lithium treatment is associated with various renal side effects and is known to induce inner medullary collecting duct (IMCD) remodeling. In animals treated with lithium, the fraction of intercalated cells (ICs), which are responsible for acid-base homeostasis, increases as compared to renal principal cells (PCs). In order to investigate the intricacies of lithium-induced IMCD remodeling, male Sprague Dawley rats were fed a lithium-enriched diet for 0,1, 2, 3, 6, 9, or 12 weeks. Read More

AKAPs-PKA disruptors increase AQP2 activity independently of vasopressin in a model of nephrogenic diabetes insipidus.

Nat Commun 2018 Apr 12;9(1):1411. Epub 2018 Apr 12.

Department of Nephrology, Tokyo Medical and Dental University (TMDU), Tokyo, 113-8510, Japan.

Congenital nephrogenic diabetes insipidus (NDI) is characterized by the inability of the kidney to concentrate urine. Congenital NDI is mainly caused by loss-of-function mutations in the vasopressin type 2 receptor (V2R), leading to impaired aquaporin-2 (AQP2) water channel activity. So far, treatment options of congenital NDI either by rescuing mutant V2R with chemical chaperones or by elevating cyclic adenosine monophosphate (cAMP) levels have failed to yield effective therapies.
