Hyponatremia associated with angioimmunoblastic lymphadenopathy.
Angioimmunoblastic lymphadenopathy (AIL) is a lympho-proliferative disorder whose clinical and histological features are now well recognized. Up to now, no attention has been focused on electrolytic disturbances associated with AIL. We report 12 cases of AIL with hyponatremia below 130 mmol/l on admission. Clinical and biological features suggest that hyponatremia of AIL is dilutional and related to plasma volume expansion. The mechanism of these hydro-electrolytic disturbances is unclear.
