Bartter syndrome: causes, diagnosis, and treatment.

Int J Nephrol Renovasc Dis 2018 9;11:291-301. Epub 2018 Nov 9.

Nephrology Division, Universidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina, São Paulo, Brazil,

Bartter syndrome is an inherited renal tubular disorder caused by a defective salt reabsorption in the thick ascending limb of loop of Henle, resulting in salt wasting, hypokalemia, and metabolic alkalosis. Mutations of several genes encoding the transporters and channels involved in salt reabsorption in the thick ascending limb cause different types of Bartter syndrome. A poor phenotype-genotype relationship due to the interaction with other cotransporters and different degrees of compensation through alternative pathways is currently reported. Read More

Living kidney donation from people at risk of nephrolithiasis, with a focus on the genetic forms.

Urolithiasis 2018 Nov 23. Epub 2018 Nov 23.

UOC Nefrologia, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

Deciding whether to accept a donor with nephrolithiasis is a multifaceted task because of the challenge of finding enough suitable donors while at the same time ensuring the safety of both donors and recipients. Until not long ago, donors with a history of renal stones or with stones emerging during screening on imaging were not considered ideal, but recent guidelines have adopted less stringent criteria for potential donors at risk of stones. This review goes through the problems that need to be approached to arrive at a wise clinical decision, balancing the safety of donors and recipients with the need to expand the organ pool.

Nephrolithiasis secondary to inherited defects in the thick ascending loop of henle and connecting tubules.

Urolithiasis 2018 Nov 20. Epub 2018 Nov 20.

Division of Nephrology and Hypertension, Inselspital, Bern University Hospital, University of Bern, Freiburgstrasse 15, 3010, Bern, Switzerland.

Twin and genealogy studies suggest a strong genetic component of nephrolithiasis. Likewise, urinary traits associated with renal stone formation were found to be highly heritable, even after adjustment for demographic, anthropometric and dietary covariates. Recent high-throughput sequencing projects of phenotypically well-defined cohorts of stone formers and large genome-wide association studies led to the discovery of many new genes associated with kidney stones.

[Bartter syndrome, severe rare orphan kidney disease: a step towards therapy through pharmacogenetic and epidemiological studies].

G Ital Nefrol 2018 May;35(3)

Dipartimento di Farmacia - Scienze del Farmaco, Università di Bari, Italia.

Bartter syndromes (BS) types 1-5 are rare salt-losing tubulopathies presenting with overlapping clinical phenotypes including marked salt wasting and hypokalemia leading to polyuria, polydipsia, volume contraction, muscle weakness and growth retardation. These diseases are due to an impairment of sodium, potassium, chloride reabsorption caused by mutations in genes encoding for ion channel or transporters expressed in specific nephron tubule segments. Particularly, BS type 3 is a clinically heterogeneous form caused by mutations in CLCNKB gene which encodes the ClC-Kb chloride channel involved in NaCl reabsorption in the renal tubule. Read More

Late-onset Bartter syndrome type II.

Clin Kidney J 2017 Oct 8;10(5):594-599. Epub 2017 May 8.

Experimental and Clinical Research Center (ECRC), a joint cooperation between the Charité Medical Faculty and the Max Delbrück Center for Molecular Medicine (MDC) in the Helmholtz Association of National Research Centers, Berlin, Germany.

Mutations in the ROMK1 potassium channel gene () cause antenatal/neonatal Bartter syndrome type II (aBS II), a renal disorder that begins , accounting for the polyhydramnios and premature delivery that is typical in affected infants, who develop massive renal salt wasting, hypokalaemic metabolic alkalosis, secondary hyperreninaemic hyperaldosteronism, hypercalciuria and nephrocalcinosis. This BS type is believed to represent a disorder of the infancy, but not in adulthood. We herein describe a female patient with a remarkably late-onset and mild clinical manifestation of BS II with compound heterozygous missense mutations, consisting of a novel c. Read More

Neonatal bartter syndrome in an extremely low birth weight baby.

Saudi J Kidney Dis Transpl 2017 Sep-Oct;28(5):1162-1164

Department of Neonatology, Lokmanya Tilak Municipal Medical College and Hospital, Mumbai, Maharashtra, India.

Early diagnosis of Bartter syndrome (BS) in the neonatal period is a clinical challenge, more so in an extremely low birth weight (ELBW) baby because of the inherent renal immaturity and the associated difficulty in fluid management. However, once a diagnosis is made, the disorder is known to respond well to fluid and electrolyte management, prostaglandin inhibitors, and potassium-sparing diuretics. Herein, we report a case of neonatal BS in a very premature ELBW infant. Read More

Zhonghua Nei Ke Za Zhi 2017 Sep;56(9):712-716

Gitelman syndrome (GS) is an autosomal recessive, salt-losing tubulopathy caused by inactivating mutations in the 123 gene that encodes the thiazide-sensitive sodium-chloride cotransporter (NCC). GS is characterized by hypokalemic metabolic alkalosis, hypomagnesemia and hypocalciuria. GS is one of the most common inherited renal tubulopathy with a prevalence estimated at about one to ten per 40 000 people. Read More
