The main determinants for the maintenance of water homeostasis are the hormone arginine-vasopressin (AVP) and thirst. Disturbances in these regulatory mechanisms can lead to the polyuria-polydipsia syndrome, which comprises of three different conditions: central diabetes insipidus (DI) due to insufficient secretion of AVP, nephrogenic DI caused by renal insensitivity to AVP action, and primary polydipsia due to excessive fluid intake and consequent physiologic suppression of AVP. It is crucial to determine the exact diagnosis because treatment strategies vary substantially...

Pharmacological chaperones recently opened new possibilities in G protein-coupled receptor drug discovery. Even more interestingly, some unique ligands combine pharmacological chaperoning and biased agonism properties, boosting their therapeutic interest in many human diseases resulting from G protein-coupled receptor mutation and misfolding. These compounds displaying dual characteristics would constitute a perfect treatment for congenital Nephrogenic Diabetes Insipidus, a typical conformational disease. This X-linked genetic pathology is mostly associated with inactivating mutations of the renal arginine-vasopressin V2 receptor leading to misfolding and intracellular retention of the receptor, causing the inability of patients to concentrate their urine in response to the antidiuretic hormone...

Acute renal failure can be caused by calcineurin inhibitors (CNIs), due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric renal failure with severe hypernatremic dehydration...

Tubulointerstitial nephritis (TIN) is the main renal involvement associated with primary Sjögren syndrome (pSS). TIN can manifest as distal renal tubular acidosis (RTA), nephrogenic diabetes insipidus, proximal tubular dysfunction, and others. We present a 31-year-old female with hypokalemic paralysis due to distal RTA (dRTA). She received symptomatic treatment and hydroxychloroquine with a good response. There is insufficient information on whether to perform a kidney biopsy in these patients or not. The evidence suggests that there is an inflammatory background and therefore a potential serious affection to these patients, such as hypokalemic paralysis...

Two processes are associated with progressive loss of renal function: 1) decreased aquaporin-2 (AQP2) expression and urinary concentrating capacity (Nephrogenic Diabetes Insipidus, NDI); and 2) changes in extracellular matrix (ECM) composition, e.g. increased collagen I (Col I) deposition, characteristic of tubule-interstitial fibrosis. AQP2 expression is regulated by both the ECM-to-intracellular scaffold protein integrin-linked kinase (ILK) by NFATc/AP1 and other transcription factors. In the present work, we used in vivo and in vitro approaches to examine ILK participation in NFATc3/AP-1-mediated increases in AQP2 gene expression...

Diabetes insipidus is a syndrome that associates both hypotonic polyuria and polydipsia, due to insufficient or ineffective arginine vasopressin (AVP) synthesis, or to AVP resistance. The diagnosis between central/renal origin, or an abnormal thirst regulation (primary polydipsia) is required to organize an adapted management. Because water deprivation tests are not reliable, it's often based on medical history, response to treatment and MRI. Copeptin is an AVP precursor which could be very helpful for the diagnosis...

Lithium is the mainstay treatment for patients with bipolar disorder, but it generally causes nephrogenic diabetes insipidus (NDI), a disorder in which the renal urine concentrating ability has become vasopressin insensitive. Li-NDI is caused by lithium uptake by collecting duct principal cells and downregulation of aquaporin-2 (AQP2) water channels, which are essential for water uptake from tubular urine. Recently, we found that the prophylactic administration of acetazolamide to mice effectively attenuated Li-NDI...

Vasopressin (AVP) induces antidiuresis, thus playing an essential role in body water and electrolyte homeostasis. Its antidiuretic effects are mediated chiefly by V2 vasopressin receptors (V2R) expressed along the distal nephron and collecting duct epithelia. NaCl reabsorption in the distal nephron, which includes the thick ascending limb (TAL) and distal convoluted tubule (DCT), largely depends on the activity of two structurally related Na-(K)-Cl cotransporters, NKCC2 in TAL and NCC in DCT. AVP-induced activation of these transporters contributes to urine concentration and renal electrolyte reabsorption...

BACKGROUND Sjögren's syndrome is an autoimmune disorder caused by the infiltration of monocytes in epithelial glandular and extra-glandular tissues. Hallmark presentations include mouth and eye dryness. Although renal involvement is uncommon in primary Sjögren's syndrome (pSS), patients may experience renal tubular acidosis type I (RTA I), tubulointerstitial nephritis, diabetes insipidus (DI), nephrolithiasis, and Fanconi syndrome. However, it is atypical to see more than 1 of these manifestations in a single patient...

Diabetes insipidus is a disease characterized by polyuria and polydipsia due to inadequate release of arginine vasopressin from the posterior pituitary gland (neurohypophyseal diabetes insipidus) or due to arginine vasopressin insensitivity by the renal distal tubule, leading to a deficiency in tubular water reabsorption (nephrogenic diabetes insipidus). This article reviews the genetics of diabetes insipidus in the context of its diagnosis, clinical presentation, and therapy.

The collecting duct of the mammalian kidney is important for the regulation of extracellular volume, osmolarity, and pH. There are two major structurally and functionally distinct cell types: principal cells and intercalated cells. The former regulates Na(+) and water homeostasis, while the latter participates in acid-base homeostasis. In vivo lineage tracing using Cre recombinase or its derivatives such as CreGFP and CreER(T2) is a powerful new technique to identify stem/progenitor cells in their native environment and to decipher the origins of the tissue that they give rise to...

Psychiatric patients treated with lithium (Li(+)) may develop nephrogenic diabetes insipidus (NDI). Although the etiology of Li(+)-induced NDI (Li-NDI) is poorly understood, it occurs partially due to reduced aquaporin-2 (AQP2) expression in the kidney collecting ducts. A mechanism postulated for this is that Li(+) inhibits adenylyl cyclase (AC) activity, leading to decreased cAMP, reduced AQP2 abundance, and less membrane targeting. We hypothesized that Li-NDI would not develop in mice lacking AC6. Whole-body AC6 knockout (AC6(-/-)) mice and potentially novel connecting tubule/principal cell-specific AC6 knockout (AC6(loxloxCre)) mice had approximately 50% lower urine osmolality and doubled water intake under baseline conditions compared with controls...

Cystinosis is the most common cause of inherited renal Fanconi syndrome in young children, and typically presents with laboratory findings of a proximal tubulopathy and corneal crystals by one year of age. We describe here renal biopsy findings in a 20-month-old patient with an atypical presentation of distal renal tubular acidosis, diabetes insipidus, and the absence of corneal crystals. Although renal biopsy is usually not necessary to establish the diagnosis of cystinosis, when the patient presents with atypical signs and symptoms, a renal biopsy may be extremely valuable...

Disruption of water and electrolyte balance is frequently encountered in clinical medicine. Regulating water metabolism is critically important. Diabetes insipidus (DI) presented with excessive water loss from the kidney is a major disorder of water metabolism. To understand the molecular and cellular mechanisms and pathophysiology of DI and rationales of clinical management of DI is important for both research and clinical practice. This chapter will first review various forms of DI focusing on central diabetes insipidus (CDI) and nephrogenic diabetes insipidus (NDI ) ...

The direct renin inhibitor aliskiren has been shown to be retained and persist in medullary collecting ducts even after treatment is discontinued, suggesting a new mechanism of action for this drug. The purpose of the present study was to investigate whether aliskiren regulates renal aquaporin expression in the collecting ducts and improves urinary concentrating defect induced by lithium in mice. The mice were fed with either normal chow or LiCl diet (40 mmol·kg dry food(-1)·day(-1) for 4 days and 20 mmol·kg dry food(-1)·day(-1) for the last 3 days) for 7 days...

Hypercalcemia can cause renal dysfunction such as nephrogenic diabetes insipidus (NDI), but the mechanisms underlying hypercalcemia-induced NDI are not well understood. To elucidate the early molecular changes responsible for this disorder, we employed mass spectrometry-based proteomic analysis of inner medullary collecting ducts (IMCD) isolated from parathyroid hormone-treated rats at onset of hypercalcemia-induced NDI. Forty-one proteins, including the water channel aquaporin-2, exhibited significant changes in abundance, most of which were decreased...

PURPOSE OF REVIEW: In nephrogenic diabetes insipidus (NDI), the kidney is unable to concentrate urine despite elevated concentrations of the antidiuretic hormone arginine-vasopressin. In congenital NDI, polyuria and polydipsia are present from birth and should be immediately recognized to avoid severe episodes of dehydration. Unfortunately, NDI is still often recognized late after a 'diagnostic odyssey' involving false leads and dangerous treatments.Once diagnosed, appropriate treatment can be started...
