Bartter syndrome: an overview
From the Department of Paediatrics, Faculty of Medicine and Health Sciences, United Arab Emirates University, Al Ain, United Arab Emirates
The term Bartter syndrome denotes a group of renal diseases which share a common denominator of hypokalaemia and metabolic alkalosis. The patch-clamp technique has made possible the analysis of single ion channels, improving our understanding of the molecular physiopathology of all the Bartter-like syndromes. Genetic mapping of each defect has further clarified the mutations involved and the possible modes of inheritance. This improved understanding has opened new avenues for therapy, improving mortality and morbidity in these patients. Another group of illnesses, the pseudo-Bartter syndrome, may produce a hypokalaemic metabolic alkalosis without primary renal disease. The underlying illness needs to be identified and treated.
