1 multicenter open-label randomized controlled trial
This is a national, multicenter, prospective, open-label randomized controlled superiority trial with stratification on the presence of neurological symptoms at inclusion and on the presence/absence of risk factors for central pontine myelinolysis (chronic alcohol abuse, malnutrition, serum potassium < 3.0 mmol/L). This is a study with two comparative groups at a ratio of (1:1): - Experimental arm: DDVAP + standard of care - Control arm: standard of care alone As already explained, due to the nature of the treatments received, investigator blinding to group assignment is not feasible. Indeed, the administration of DDAVP leads to an important decrease in urine output and increase in urine osmolarity which are clinically obvious very rapidly. However, all investigators will be unaware of aggregate outcomes during the study and brain MRI imaging will be performed and analyzed blinded to the randomization group (see secondary outcomes section). Biological analyses as well as statistical analyses will be performed blinded to treatment group.
Randomised Controlled None Experimental arm: DDAVP (IMP) + Standard of care (SOC)

1) IMP = DDAVP = MINIRIN©

2) SOC = standard hyponatremia treatment in accordance with international recommendations (without DDAVP administration*):
* DDAVP can be used in rescue strategy: administration when the target SNa is exceeded and overcorrection has already occurred.
- Presence of neurological symptoms: NaCl 3% 150 ml or 2mL/kg in case of weight < 50kg or > 120kg over 20 min
- Absence of neurological symptoms isotonic fluid (NaCl 0.9%) but never hypotonic
- Route of administration: intravenous
- Duration of treatment: 48h maximum
- In case of suspected overcorrection (= sudden significant diuresis or obviously overcorrection): Stop NaCl 3% infusion + glucose hypotonic fluid (D5 or D2.5): 10 ml/kg over 1h under strict monitoring.
- In case of hypovolemia: saline solution (NaCL 0.9%) at a rate of 0.5 à 1 ml/kg/h
- In case of hypervolemia: physicians are allowed to use furosemide
- In case of hypokalaemia: potassium chloride (KCl), amount of KCl administration will depend on severity of hypokalemia. Physicians will be made aware that KCl administration may contribute to the rise of SNa.During potassium administration, the rate of 3% saline solution infusion should be slowed proportionally.
