Pediatric nephrology (Berlin, Germany)·2014

This study investigated primary nocturnal enuresis (PNE) treatment with desmopressin (dDAVP). Findings suggest dDAVP acts centrally, not by supplementing arginine vasopressin (AVP) deficiency in enuretic children.

Area of Science:

  • Pediatric Nephrology
  • Endocrinology
  • Neuroscience

Background:

  • Primary nocturnal enuresis (PNE) treatment often involves desmopressin (dDAVP).
  • The underlying hypothesis suggests insufficient nocturnal arginine vasopressin (AVP) secretion in children with PNE.
  • Doubts persist regarding the theoretical basis of dDAVP treatment for PNE.

Purpose of the Study:

  • To investigate arginine vasopressin (AVP) regulation in children with PNE.
  • To evaluate the effect of dDAVP on short-term memory in children with PNE.
  • To challenge the AVP deficiency hypothesis in PNE.

Main Methods:

  • Compared plasma AVP levels after fluid restriction in children with PNE versus healthy controls.
  • Assessed short-term memory in children with PNE undergoing dDAVP treatment.

  • Analyzed AVP secretion in relation to plasma osmolality.

    • Main Results:

    • Children with PNE exhibited significantly higher plasma AVP concentrations than controls to maintain osmolality.
    • Children treated with dDAVP for PNE demonstrated significantly improved short-term memory.
    • Results align with AVP secretion being a function of plasma osmolality.

    Conclusions:

    • The findings contradict the hypothesis of AVP deficiency in enuretic children requiring supplementation.
    • Results indicate a potential central action of dDAVP.
    • A defect at the central AVP receptor level or in the signal transduction pathway is suggested.
