Popis: | Objective: Arginine vasopressin (AVP; antidiuretic hormone) and corticotropin-releasing hormone are the two major secretagogues of hypophyseal adrenocorticotropin (ACTH). Interleukin-6 (IL-6) is a potent stimulator of thehuman hypothalamic-pituitary-adrenal axis (HPA) and a secretagogue of both parvocellular and magnocelullar AVP. We have previously suggested that IL-6-stimulated AVP secretion may be the origin of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) in inflammatory conditions. Study design: To further elucidate the relationship between IL-6 and SIADH as well as IL-6 and HPA axis activity, we studied eight previously healthy children (age 6.3 ′ 4.8 [mean ′ SD] years, weight 23.8 ′ 10.5 kg) who - after sustaining head trauma - presented SIADH during hospitalization (for 7.1 ′ 3.8 days) in the pediatric intensive care unit (P-ICU). Routine blood samples were taken twice daily at 08:00 and 20:00 hours. All children but one survived. Measurements included blood and urine osmolality (BlOsm and UrOsm, respectively), serum cortisol (F) and IL-6, plasma ACTH and AVP. Correlations were assessed with linear regression among the areas under the curve (AUC) of BlOsm, UrOsm, ACTH, F, IL-6 and AVP, separately for BlOsm values |
