[Congenital multiple anomaly syndrome with recurrent vomiting accompanied with latent SIADH; a case report].
A 13-year-old girl with multiple minor anomalies and severe mental retardation had recurrent episodes of severe vomiting. At each episode, marked elevations of plasma ADH, ACTH, cortisol and salivary type amylase were found with reduction of serum Na level and osmolarity. This case is similar to that with periodic ACTH-ADH discharge syndrome (Sato). However, she had underlying disease, and neither hypertension nor depressive state was observed. Latent SIADH was detected by water loading test. After DZP administration, ADH secretion was suppressed in this test, and actually the duration of each attack was shortened. We considered that her vomiting was closely related with hypothalamic dysfunction, especially latent SIADH.
