Adipsia is a disease characterized by the absence of thirst even in the It is a rare condition that typically presents as hypernatremic dehydration. We describe two sisters with chronic hypernatremia, lack of thirst, and inappropriate osmoregulated vasopressin secretion. Only one sister, who presented with. Adipsia, also known as hypodipsia, is a symptom of inappropriately decreased or absent . Type A (essential hypernatremia syndrome) involves an increase of the level in which solvent molecules can pass through cell membranes (osmotic.

Adipsic hypernatremia patients with specific immune responses to SFO display common clinical features.

A complete evaluation of anterior pituitary functions was carried out for all patients at diagnosis and was repeated during follow-up if deemed necessary on the basis of clinical examination and serum free T 4 and morning cortisol determinations.

Views Read Edit View history. Hypo- and hypernatremia result in similar clinical symptoms, such as irritability, lethargy, weakness, nausea, seizures, and coma, but mortality is higher for hyponatremia Future Directions There are still two unresolved points related to the pathophysiology of this disorder: The only patient in our study with this vascular abnormality also had no visible hyperintense signal for the PP.

In patients developing adipsic hypernatremia caused by congenital abnormalities, such as septo-optic dysplasia, clinical characteristics often present as neurodevelopmental delay, seizures, thermal dysregulation, and anterior pituitary dysfunction [defects in the release control of GH, thyroid stimulating hormone TSHand ACTH] Conclusion Adipsic hypernatremia patients with specific immune responses to SFO display common clinical features.


The AVP release in this subtype occurs with normally functioning levels of osmoregulation.

They are therefore susceptible to axipsic. These patients generally had a poor prognosis, often due to respiratory failure, such as apnea. Approach to the Patient With Hypogonadotropic Hypogonadism.

Adipsic persons may undergo training to learn when it is necessary that they drink water. We are grateful to Drs. Injection of patient Ig into mice led to complement deposition, infiltration of inflammatory cells, and damage to the mouse SFO area resulting from apoptosis 14 Sign in to make a comment Sign in to your personal account.

Adipsia – Wikipedia

There is debate over whether osmoreceptor resetting could lead to the increase in threshold. Neonatal central diabetes insipidus CDI with or without adipsia is a very rare complication of various complex hypothalamic disorders.

J Pediatr Endocrinol Metab ; Obesity, growth hormone and weight loss. There are clear clinical differences in the presentation of CDI in infants and older children. Type C is generally the adipsia type found in patients with adipsic diabetes insipidus. New strategies to prevent specific inflammatory conditions would be required to treat these patients; a trial to reduce or eliminate patient autoantibodies deserves consideration.

The anterior hypothalamus is in close proximity to osmoreceptors which regulate the secretion of antidiuretic hormone ADH.
