[Cerebral salt loss as Schwartz-Bartter-syndrome in childhood (author's transl)]. 1976

M U Müller, and J R Bierich

Schwartz-Bartter-syndrome as a consequence of severe cerebral alterations like bacterial and tuberculous meningitis, encephalitis, hydrocephalus and brain haemorrhage has been observed in 7 cases. Massive natriuresis is followed by marked hyponatremia and hypochloremia which may lead to an intracellular brain edema. Sodium administered even in high dosage is lost rapidly through the kidney, and does not normalize the serum level of sodium. The Schwartz-Bartter-syndrome is caused by inadequatly elevated ADH-secretion with consecutive water retention and an increase in plasma volume. Consecutively an increased excretion of sodium takes place causing a substantial loss of bound water. An analogous situation was seen in a child with neurohormonal diabetes insipidus after an overdosage of ADH, which resulted in a hypervolemia, marked hyponatremia and massive natriuresis. The increased excretion of sodium may be the result of reduced reabsorption of sodium in the proximal tubuli of the kidney, caused by a humeral natriuretic factor (the socalled "third factor"). In the serum of one of our patients an increased natriuretic activity could be shown; this is the first time in a child with Schwartz-Bartter-syndrome.

D008581 Meningitis Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (CARCINOMATOUS MENINGITIS), and other inflammatory conditions may produce this syndrome.

D009318 Natriuresis Sodium excretion by URINATION. Natriureses
D009994 Osmolar Concentration The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per liter of solution. Osmolality is expressed in terms of osmoles of solute per kilogram of solvent.

D001810 Blood Volume Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME. Blood Volumes,Volume, Blood,Volumes, Blood
D001927 Brain Diseases Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.

D001929 Brain Edema Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).
