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...

INTRODUCTION: Autoimmune hypophysitis (AH) has a variable clinical presentation and natural history; likewise, its response to glucocorticoid therapy is often unpredictable. OBJECTIVE: To identify clinical and radiological findings associated with response to glucocorticoids. DESIGN AND METHODS: 12 consecutive patients with AH, evaluated from 2008 to 2016. AH was the exclusion diagnosis after ruling out other pituitary masses and secondary causes of hypophysitis...

BACKGROUND: Autoimmune hypothalamitis, which is among the causes of acquired central diabetes insipidus, has been described very rarely in the literature. This condition is probably provoked by the production of anti-vasopressin secreting cells antibodies and anti-hypothalamus antibodies, and is often associated with pituitary or polyendocrine autoimmunity. Correct diagnosis and immediate treatment are essential in order to avoid the progression of the pathological process. CASE DESCRIPTION: A woman diagnosed with central diabetes insipidus 12 year ago, suffering from panhypopituitarism and mild memory deficit came to our attention...

Erdheim-Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis characterized by a xanthogranulomatous infiltration of tissues by spumous histiocytes. Neurological involvement is frequent, but ischemic strokes have been exceptionally described. We report the case of a 68-year-old woman who presented with an acute ischemic stroke associated with a multisystemic disorder including insipidus diabetes, infiltration of the aorta and the carotid arteries, perirenal infiltration, aortitis, and lytic bone lesions...

Central diabetes insipidus (DI) is a rare clinical entity characterized by low circulating levels of antidiuretic hormone (ADH) presenting with polyuria and volume depletion. Pituitary surgery is the most common cause of central DI in adults. Pituitary and hypothalamic disease, particularly invasive neoplasms, rarely cause DI, being idiopathic cases responsible for the majority of non-surgical cases. HIV patients, especially those with poor virulogical control, are prone to the development of CNS neoplasms, particularly lymphomas...

Lithium is the mainstay treatment for patients with bipolar disorder, but 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 AQP2 water channels, which are essential for water uptake from pro-urine. Recently, we found that the prophylactic administration of acetazolamide to mice effectively attenuated Li-NDI. To evaluate whether acetazolamide might benefit lithium-treated patients, we administered acetazolamide to mice with established Li-NDI and six patients with a lithium-induced urinary concentrating defect...

BACKGROUND: Sheehan's syndrome occurs because of severe postpartum hemorrhage causing ischemic pituitary necrosis. Sheehan's syndrome is a well-known condition that is generally diagnosed several years postpartum. However, acute Sheehan's syndrome is rare, and clinicians have little exposure to it. It can be life-threatening. There have been no reviews of acute Sheehan's syndrome and no reports of successful pregnancies after acute Sheehan's syndrome. We present such a case, and to understand this rare condition, we have reviewed and discussed the literature pertaining to it...

BACKGROUND: Neonatal central diabetes insipidus (NCDI) remains a therapeutic challenge, as extremely low doses of enteral desmopressin cannot be titrated with current preparations. The aim of this study was to describe the use of orally administered dilute desmopressin in NCDI. METHODS: Nasal desmopressin (100 μg/mL) was diluted in 0.9% saline to 10 μg/mL. Infants were treated with 1-5 μg and doses were titrated to a twice-daily regimen. The feed volume was 150 mL/kg/day and titrated according to weight gain...

PURPOSE: Central diabetes insipidus is characterised by arginine vasopressin deficiency. Oxytocin is structurally related to vasopressin and is synthesised in the same hypothalamic nuclei, thus we hypothesised that patients with acquired central diabetes insipidus and anterior hypopituitarism would display an oxytocin deficiency. Moreover, psychological research has demonstrated that oxytocin influences social and emotional behaviours, particularly empathic behaviour. We therefore further hypothesised that central diabetes insipidus patients would perform worse on empathy-related tasks, compared to age-matched and gender-matched clinical control (clinical control-isolated anterior hypopituitarism) and healthy control groups...

Hyponatremia can be a complication of opioid therapy, which has been postulated to occur secondary to inappropriate antidiuretic hormone secretion (syndrome of inappropriate antidiuretic hormone secretion [SIADH]). We report severe hyponatremia following wisdom teeth extraction with opioid analgesia in a 19-year-old female with diabetes insipidus (DI) and acquired panhypopituitarism that challenges this theory. As this patient has DI, we believe opioid treatment caused severe hyponatremia by the following mechanisms: (1) Opioids have a direct antidiuretic effect independent of changes in ADH, as demonstrated in Brattleboro rats with central DI...

OBJECTIVE: Surgical removal plays an important role in treating children's craniopharyngioma. For a safe and minimally invasive craniotomy, a reformed surgical modality was proposed in this paper by combining the insertion of an Ommaya reservoir system (ORS) by stereotactic puncture, aspiration of cystic fluid in 2-day interval for consecutive 7-10 days, and the delayed tumor resection. PATIENTS AND METHODS: Eleven patients (aged from 5 to 9 years old) with giant cystic craniopharyngiomas who had undergone the reformed surgical modality during November 2014 and December 2015 were collected as group A...

The most common, and usually the only, endocrine disturbance in patients with hypothalamic hamartoma (HH) and epilepsy is central precocious puberty (CPP). The mechanism for CPP associated with HH may relate to ectopic generation and pulsatile release of gonadotropin-releasing hormone (GnRH) from the HH, but this remains an unproven hypothesis. Possible regulators of GnRH release that are intrinsic to HH tissue include the following: (1) glial factors (such as transforming growth factor α[TGFα) and (2) γ-aminobutyric acid (GABA)-mediated excitation...

BACKGROUND: Xanthomatous hypophysitis (XH) is extremely rare. Only 27 cases have been reported in the literature. No XH patient presenting with diabetes insipidus (DI) has been completely cured through surgery. Here, we describe the first XH case of a DI patient whose pituitary function was normalized postoperatively, without hormone replacement therapy. CASE DESCRIPTION: A 41-year-old woman suffered from polydipsia, DI, headache and breast discharge. Laboratory investigation revealed hyperprolactinemia...

INTRODUCTION: Colloid cysts are the most common pathologic lesions of the third ventricle. Although they are histologically benign, they may grow and can cause the hydrocephalus. A 5-year-old male patient underwent to surgery with the diagnosis of colloid cyst. In operation, after the anterior transcallosal approach, the cyst was punctured by syringe and obviously pus aspirated. CONCLUSION: Colloid cysts mostly remain silent and detected incidentally. Although it is rarely defined, rhinorrhea, hypopituitarism, diabetes insipidus, spasmodic torticollis, drop attack, aseptic meningitis, and coexistence with neurocysticercosis have been reported, but this is the first reported case of an infected colloid cyst...

REVIEW
Sebastian Bachmann, Kerim Mutig
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...

We report a case of a 17-year-old male who presented with pain in his right first toe. His pain and swelling had worsened and x-rays of his foot revealed erosive changes of the great toe distal phalanx suggesting possible osteomyelitis. His co-morbidities were morbid obesity and diabetes insipidus. He was admitted to the hospital, blood cultures were drawn, and he was started on vancomycin for presumed bacterial osteomyelitis. He underwent incision and drainage of the fluctuant abscess of the toe, where a culture of the wound was taken...

Erdheim-Chester Disease (ECD) is a rare, potentially fatal, multi-organ myeloid neoplasm occurring mainly in adults. The diagnosis is established by clinical, radiologic, and histologic findings; ECD tumors contain foamy macrophages that are CD68+, CD163+, CD1a-, and frequently S100-. The purpose of this report is to describe the clinical and molecular variability of ECD. Sixty consecutive ECD patients (45 males, 15 females) were prospectively evaluated at the NIH Clinical Center between 2011 and 2015. Comprehensive imaging and laboratory studies were performed, and tissues were examined for BRAF V600E and MAPK pathway mutations...
