[Morphology of the juxtaglomerular appartus in Bartter's syndrome (hyperplasia of the juxtaglomerular complex with secondary aldosteronism without hypertension)]. 1974

P Herranz, and L Ceballos, and G Herranz

In this paper a case of Bartter's syndrome is presented, stressing two facts: the asymmetric hyperplasia of the juxtaglomerular apparatus mostly located at the efferent arteriole. In the other hand, a new interpretation is suggested over so called "proliferative glomerulitis" seen in this syndrome. This hypothesis is based on data suggesting not a true inflammatory process but a similar lesion observed in the postnatal glomerular regression.

UI	MeSH Term	Description	Entries
D006965	Hyperplasia	An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.	Hyperplasias
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D007606	Juxtaglomerular Apparatus	A complex of cells consisting of juxtaglomerular cells, extraglomerular mesangium lacis cells, the macula densa of the distal convoluted tubule, and granular epithelial peripolar cells. Juxtaglomerular cells are modified SMOOTH MUSCLE CELLS found in the walls of afferent glomerular arterioles and sometimes the efferent arterioles. Extraglomerular mesangium lacis cells are located in the angle between the afferent and efferent glomerular arterioles. Granular epithelial peripolar cells are located at the angle of reflection of the parietal to visceral angle of the renal corpuscle.	Apparatus, Juxtaglomerular

D006929	Hyperaldosteronism	A condition caused by the overproduction of ALDOSTERONE. It is characterized by sodium retention and potassium excretion with resultant HYPERTENSION and HYPOKALEMIA.

D001477	Bartter Syndrome	A group of disorders caused by defective salt reabsorption in the ascending LOOP OF HENLE. It is characterized by severe salt-wasting, HYPOKALEMIA; HYPERCALCIURIA; metabolic ALKALOSIS, and hyper-reninemic HYPERALDOSTERONISM without HYPERTENSION. There are several subtypes including ones due to mutations in the renal specific SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.
