We experienced four cases with hyponatremia due to SIADH, which seems to be related to inflammation. The plasma Na concentration decreased when the patients had fever and increased plasma CRP level. In such conditions, plasma vasopressin concentration (PAVP) and the plasma interleukin-6 (IL-6) concentration were increased. There was significant correlation between them. The animal experiments were carried out to investigate the role of interleukin in the development of SIADH. Intravenous administrations of IL-1 beta increased AVP, atrial natriuretic hormone (ANH) and ACTH. The changes in AVP and ACTH were abolished by the pretreatment with an intravenous administration of indomatacin. Moreover, the intracerebroventricular administration (ICV) of IL-1 beta also increased AVP, atrial natriuretic hormone (ANH) and ACTH. The pretreatment of indomatacin attenuated the changes in AVP and ACTH. The intravenous administration of IL-1 beta increased the urinary sodium excretion. The pretreatement of HS142-1, an ANH antagonist, abolished the increase in urinary sodium excretion induced by IL-1 beta. These results suggested that the interleukin play an important role in the development of SIADH associated with inflammation.
