Pediatric central diabetes insipidus (CDI)

Pediatric central diabetes insipidus (cen·​tral - di·​a·​be·​tes - in·​sip·​i·​dus) or CDI is a rare condition in which the kidneys are unable to concentrate (or dilute) the body’s urine.

What is pediatric central diabetes insipidus (CDI)?

Normalmente, el organismo libera una ADH (hormona antidiurética o vasopresina) desde la hipófisis hacia el torrente circulatorio, donde se desplaza hacia los riñones. Su función es concentrar la orina y ayudar a los riñones a regular la cantidad de agua en el organismo.

En el caso de los niños que tienen diabetes insípida, es posible que el organismo no libere suficiente ADH y que los riñones no reciban la cantidad de ADH adecuada. En algunos niños, existe la posibilidad de que los riñones no respondan a la ADH. Without the ability to concentrate urine, a child’s body will release large amounts of diluted urine and the body will become dehydrated

What are the different types of pediatric central diabetes insipidus (CDI)?

Existen dos tipos de diabetes insípida: 

  1. Central diabetes insipidus - Central diabetes insipidus happens when not enough ADH is produced or secreted from the pituitary gland. This is the most common type of the disease
  2. Nephrogenic diabetes insipidus - Nephrogenic diabetes insipidus happens when normal levels of ADH are produced and secreted, but the kidneys do not respond to it normally. Por lo general, esto se debe a un problema genético en los riñones. 

What are the signs and symptoms of pediatric central diabetes insipidus (CDI)?

Los síntomas de ambos tipos de diabetes insípida son similares.

What are the causes of pediatric central diabetes insipidus (CDI)?

  • Central diabetes insipidus is caused by damage to the hypothalamus or pituitary gland. This may be due to a head injury, brain surgery, brain tumor, pituitary tumor, encephalitis or meningitis. It may also be due to a genetic disorder. 
  • Nephrogenic diabetes insipidus is the result of a defect in the kidneys, which may be caused by a genetic disorder. Asimismo, las causas pueden ser enfermedad renal, hipercalcemia o la ingesta de determinados medicamentos, como el litio.
