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.
Solute Carrier Family 12, Member 1
An inherited renal disorder characterized by defective NaCl reabsorption in the convoluted DISTAL KIDNEY TUBULE leading to HYPOKALEMIA. In contrast with BARTTER SYNDROME, Gitelman syndrome includes hypomagnesemia and normocalcemic hypocalciuria, and is caused by mutations in the thiazide-sensitive SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.
Failure to Thrive
A hereditary or acquired form of generalized dysfunction of the PROXIMAL KIDNEY TUBULE without primary involvement of the KIDNEY GLOMERULUS. It is usually characterized by the tubular wasting of nutrients and salts (GLUCOSE; AMINO ACIDS; PHOSPHATES; and BICARBONATES) resulting in HYPOKALEMIA; ACIDOSIS; HYPERCALCIURIA; and PROTEINURIA.
Potassium Channels, Inwardly Rectifying
Encyclopedias as Topic
Abnormally low potassium concentration in the blood. It may result from potassium loss by renal secretion or by the gastrointestinal route, as by vomiting or diarrhea. It may be manifested clinically by neuromuscular disorders ranging from weakness to paralysis, by electrocardiographic abnormalities (depression of the T wave and elevation of the U wave), by renal disease, and by gastrointestinal disorders.

Sodium Chloride Symporters
A cell surface receptor for INSULIN. It comprises a tetramer of two alpha and two beta subunits which are derived from cleavage of a single precursor protein. The receptor contains an intrinsic TYROSINE KINASE domain that is located within the beta subunit. Activation of the receptor by INSULIN results in numerous metabolic changes including increased uptake of GLUCOSE into the liver, muscle, and ADIPOSE TISSUE.
A condition of abnormally high AMNIOTIC FLUID volume, such as greater than 2,000 ml in the LAST TRIMESTER and usually diagnosed by ultrasonographic criteria (AMNIOTIC FLUID INDEX). It is associated with maternal DIABETES MELLITUS; MULTIPLE PREGNANCY; CHROMOSOMAL DISORDERS; and congenital abnormalities.
A group of intracellular-signaling serine threonine kinases that bind to RHO GTP-BINDING PROTEINS. They were originally found to mediate the effects of rhoA GTP-BINDING PROTEIN on the formation of STRESS FIBERS and FOCAL ADHESIONS. Rho-associated kinases have specificity for a variety of substrates including MYOSIN-LIGHT-CHAIN PHOSPHATASE and LIM KINASES.

A mutation linked with Bartter's syndrome locks Kir 1.1a (ROMK1) channels in a closed state. (1/139)Mutations in the inward rectifying renal K(+) channel, Kir 1.1a (ROMK), have been linked with Bartter's syndrome, a familial salt-wasting nephropathy. One disease-causing mutation removes the last 60 amino acids (332-391), implicating a previously unappreciated domain, the extreme COOH terminus, as a necessary functional element. Consistent with this hypothesis, truncated channels (Kir 1.1a 331X) are nonfunctional. In the present study, the roles of this domain were systematically evaluated. When coexpressed with wild-type subunits, Kir 1.1a 331X exerted a negative effect, demonstrating that the mutant channel is synthesized and capable of oligomerization. Plasmalemma localization of Kir 1.1a 331X green fluorescent protein (GFP) fusion construct was indistinguishable from the GFP-wild-type channel, demonstrating that mutant channels are expressed on the oocyte plasma membrane in a nonconductive or locked-closed conformation. Incremental reconstruction of the COOH terminus identified amino acids 332-351 as the critical residues for restoring channel activity and uncovered the nature of the functional defect. Mutant channels that are truncated at the extreme boundary of the required domain (Kir 1.1a 351X) display marked inactivation behavior characterized by frequent occupancy in a long-lived closed state. A critical analysis of the Kir 1.1a 331X dominant negative effect suggests a molecular mechanism underlying the aberrant closed-state stabilization. Coexpression of different doses of mutant with wild-type subunits produced an intermediate dominant negative effect, whereas incorporation of a single mutant into a tetrameric concatemer conferred a complete dominant negative effect. This identifies the extreme COOH terminus as an important subunit interaction domain, controlling the efficiency of oligomerization. Collectively, these observations provide a mechanistic basis for the loss of function in one particular Bartter's-causing mutation and identify a structural element that controls open-state occupancy and determines subunit oligomerization. Based on the overlapping functions of this domain, we speculate that intersubunit interactions within the COOH terminus may regulate the energetics of channel opening. (+info)
Channelopathies of inwardly rectifying potassium channels. (2/139)Mutations in genes encoding ion channels have increasingly been identified to cause disease conditions collectively termed channelopathies. Recognizing the molecular basis of an ion channel disease has provided new opportunities for screening, early diagnosis, and therapy of such conditions. This synopsis provides an overview of progress in the identification of molecular defects in inwardly rectifying potassium (Kir) channels. Structurally and functionally distinct from other channel families, Kir channels are ubiquitously expressed and serve functions as diverse as regulation of resting membrane potential, maintenance of K(+) homeostasis, control of heart rate, and hormone secretion. In humans, persistent hyperinsulinemic hypoglycemia of infancy, a disorder affecting the function of pancreatic beta cells, and Bartter's syndrome, characterized by hypokalemic alkalosis, hypercalciuria, increased serum aldosterone, and plasma renin activity, are the two major diseases linked so far to mutations in a Kir channel or associated protein. In addition, the weaver phenotype, a neurological disorder in mice, has also been associated with mutations in a Kir channel subtype. Further genetic linkage analysis and full understanding of the consequence that a defect in a Kir channel would have on disease pathogenesis are among the priorities in this emerging field of molecular medicine.

Dose related growth response to indometacin in Gitelman syndrome. (3/139)Growth failure is a recognised feature of Gitelman syndrome, although it is not as frequent as in Bartter syndrome. Indometacin is reported to improve growth in Bartter syndrome, but not in Gitelman syndrome, where magnesium supplements are recommended. This paper presents 3 sisters with Gitelman syndrome who could not tolerate magnesium supplements, and whose hypotension and polyuria were eliminated by taking 2 mg/kg/day indometacin, but who grew poorly. However, increasing the indometacin dose to 4 mg/kg/day improved their growth significantly, without changing their symptoms or biochemistry. Gastrointestinal haemorrhage necessitated the use of misoprostol. (+info)
pH gating of ROMK (K(ir)1.1) channels: control by an Arg-Lys-Arg triad disrupted in antenatal Bartter syndrome. (4/139)Inward-rectifier K(+) channels of the ROMK (K(ir)1.1) subtype are responsible for K(+) secretion and control of NaCl absorption in the kidney. A hallmark of these channels is their gating by intracellular pH in the neutral range. Here we show that a lysine residue close to TM1, identified previously as a structural element required for pH-induced gating, is protonated at neutral pH and that this protonation drives pH gating in ROMK and other K(ir) channels. Such anomalous titration of this lysine residue (Lys-80 in K(ir)1.1) is accomplished by the tertiary structure of the K(ir) protein: two arginines in the distant N and C termini of the same subunit (Arg-41 and Arg-311 in K(ir)1.1) are located in close spatial proximity to the lysine allowing for electrostatic interactions that shift its pK(a) into the neutral pH range. Structural disturbance of this triad as a result from a number of point mutations found in patients with antenatal Bartter syndrome shifts the pK(a) of the lysine residue off the neutral pH range and results in channels permanently inactivated under physiological conditions. Thus, the results provide molecular understanding for normal pH gating of K(ir) channels as well as for the channel defects found in patients with antenatal Bartter syndrome. (+info)
Novel mutations in thiazide-sensitive Na-Cl cotransporter gene of patients with Gitelman's syndrome. (5/139)Gitelman's syndrome (GS) is an autosomal recessive disorder characterized by metabolic alkalosis, hypokalemia, hypomagnesemia, and hypocalciuria that has recently been reported to be linked to thiazide-sensitive Na-Cl cotransporter (TSC) gene mutations. In this study, possible mutations in the TSC gene of six Japanese patients clinically diagnosed with GS were investigated. Twenty-six exons encoding TSC were amplified by PCR and then completely sequenced by the direct sequencing method. Patient A showed a missense mutation of Arg 642 to Cys on the paternal allele and a missense mutation of Val 578 to Met and a 2-bp deletion (nucleotide 2543-2544) on the maternal allele. This deletion results in a frameshift that alters codon 837 to encode a stop signal rather than phenylalanine, and it is predicted to lead to loss of the latter half of the intracellular carboxy terminus. In the second family, two affected sisters, patients B and C, had a homozygous missense mutation of Thr 180 to Lys. Both of their parents, who are consanguineously married, have a heterozygous Thr180Lys mutation. Patient D has a homozygous mutation Thr180Lys, which is the same as the second family. Haplotype analysis indicates that patients B and C are not related to patient D. In patients E and F, we could identify only one mutant allele; Ala569Glu and Leu849His, respectively. All of the mutations identified are novel except for the Arg642Cys mutation, which has been found in a Japanese GS patient. Although further in vitro study is required to prove that the mutations are responsible for GS, it is possible that Thr180Lys and Arg642Cys mutations might be common mutations in Japanese GS. (+info)
Uncompensated polyuria in a mouse model of Bartter's syndrome. (6/139)We have used homologous recombination to disrupt the mouse gene coding for the NaK2Cl cotransporter (NKCC2) expressed in kidney epithelial cells of the thick ascending limb and macula densa. This gene is one of several that when mutated causes Bartter's syndrome in humans, a syndrome characterized by severe polyuria and electrolyte imbalance. Homozygous NKCC2-/- pups were born in expected numbers and appeared normal. However, by day 1 they showed signs of extracellular volume depletion (hematocrit 51%; wild type 37%). They subsequently failed to thrive. By day 7, they were small and markedly dehydrated and exhibited renal insufficiency, high plasma potassium, metabolic acidosis, hydronephrosis of varying severity, and high plasma renin concentrations. None survived to weaning. Treatment of -/- pups with indomethacin from day 1 prevented growth retardation and 10% treated for 3 weeks survived, although as adults they exhibited severe polyuria (10 ml/day), extreme hydronephrosis, low plasma potassium, high blood pH, hypercalciuria, and proteinuria. Wild-type mice treated with furosemide, an inhibitor of NaK2Cl cotransporters, have a phenotype similar to the indomethacin-rescued -/- adults except that hydronephrosis was mild. The polyuria, hypercalciuria, and proteinuria of the -/- adults and furosemide-treated wild-type mice were unresponsive to inhibitors of the renin angiotensin system, vasopressin, and further indomethacin. Thus absence of NKCC2 in the mouse causes polyuria that is not compensated elsewhere in the nephron. The NKCC2 mutant animals should be valuable for uncovering new pathophysiologic and therapeutic aspects of genetic disturbances in water and electrolyte recovery by the kidney. (+info)
Bartter syndrome: an overview. (7/139)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.

Functional and structural analysis of ClC-K chloride channels involved in renal disease. (8/139)ClC-K channels belong to the CLC family of chloride channels and are predominantly expressed in the kidney. Genetic evidence suggests their involvement in transepithelial transport of chloride in distal nephron segments; ClC-K1 gene deletion leads to nephrogenic diabetes insipidus in mice, and mutations of the hClC-Kb gene cause Bartter's syndrome type III in humans. Expression of rClC-K1 in Xenopus oocytes yielded voltage-independent currents that were pH-sensitive, had a Br(-) > NO(3)(-) = Cl(-) > I(-) conductance sequence, and were activated by extracellular calcium. A glutamate for valine exchange at amino acid position 166 induced strong voltage dependence and altered the conductance sequence of ClC-K1. This demonstrates that rClC-K1 indeed functions as an anion channel. By contrast, we did not detect currents upon hClC-Kb expression in Xenopus oocytes. Using a chimeric approach, we defined a protein domain that, when replaced by that of rClC-K1, allowed the functional expression of a chimera consisting predominantly of hClC-Kb. Its currents were linear and were inhibited by extracellular acidification. Contrasting with rClC-K1, they displayed a Cl(-) > Br(-)> I(-) > NO(3)(-) conductance sequence and were not augmented by extracellular calcium. Insertion of point mutations associated with Bartter's syndrome type III destroyed channel activity. We conclude that ClC-K proteins form constitutively open chloride channels with distinct physiological characteristics. (+info)
Bartter syndrome - Wikipedia
Bartter syndrome is a rare inherited defect in the thick ascending limb of the loop of Henle. It is characterized by low potassium levels (hypokalemia), increased blood pH (alkalosis), and normal to low blood pressure. There are two types of Bartter syndrome: neonatal and classic. A closely associated disorder, Gitelman syndrome, is milder than both subtypes of Bartter syndrome. In 90% of cases, neonatal Bartter syndrome is seen between 24 and 30 weeks of gestation with excess amniotic fluid (polyhydramnios). After birth, the infant is seen to urinate and drink excessively (polyuria, and polydipsia, respectively). Life-threatening dehydration may result if the infant does not receive adequate fluids. About 85% of infants dispose of excess amounts of calcium in the urine (hypercalciuria) and kidneys (nephrocalcinosis), which may lead to kidney stones. In rare occasions, the infant may progress to renal failure. Patients with classic Bartter syndrome may have symptoms in the first two years of ...

N2 - Bartter syndrome comprises a group of rare autosomal-recessive salt-losing disorders with distinct phenotypes, but one unifying pathophysiology consisting of severe reductions of sodium reabsorption caused by mutations in five genes expressed in the thick ascending limb of Henle, coupled with increased urinary excretion of potassium and hydrogen, which leads to hypokalemic alkalosis. Bartter syndrome type IV, caused by loss-of-function mutations in barttin, a subunit of chloride channel CLC-Kb expressed in the kidney and inner ear, usually occurs in the antenatal-neonatal period. We report an unusual case of late onset presentation of Bartter syndrome IV and mild phenotype in a 20 years-old man who had hypokalemia, deafness, secondary hyperparathyroidism and erythrocytosis.

Bartter/Gitelman syndrome - Clinical Advisor
Bartter syndrome refers to several clinical disorders that result from defective sodium chloride (NaCl) reabsorption in the thick ascending limb of the loop of Henle, the site of action of loop diuretics. Gitelman syndrome results from a defect in the NaCl cotransporter in the distal convoluted tubule, where thiazide diuretics exert their effects, leading to similar but milder physiologic changes.. Failure to reabsorb NaCl in these two areas of the kidney leads to excess salt and water loss and stimulation of the renin-angiotensin-aldosterone system. Elevated aldosterone leads to increased potassium and hydrogen exchange for sodium in the distal tubule and results in the hypokalemia and metabolic alkalosis seen in both syndromes.. Antenatal Bartter syndrome (type I, II, IV, also called hyperprostaglandin E syndrome) is the most severe clinical variant. It is generally associated with prenatal polyhydramnios and premature delivery. Patients are noted to have severe electrolyte abnormalities, ...
Antenatal Bartter Syndrome, Information for Medical Personnel : BartterSite.org
Despite the recent sucesses in elucidating the molecular pathogenesis of the Bartter-like syndromes, therapies designed to arrest or correct the primary defects are not yet available. Therefore, the main therapeutic objective is to ameliorate the hypokalemic, hypochloremic, metabolic alkalosis. Potassium chloride supplementation is the mainstay of therapy. Oral supplementation alone is usually ineffective, however, in normalizing serum potassium concentrations, probably because large amounts of exogenous K further stimulates aldosterone synthesis with resultant increases in hyperkaliuria. The addition of K-sparing diuretics, eg, spironolactone, amilioride, or triamterene, may help to correct the total body K balance. In fact, the therapeutic combination of the K supplementation and K-sparing diuretics has been associated with increased growth rates in affected children. In young infants, marked urinary salt wasting may also occur and necessitate NaCl supplementation. Indomethacin therapy ...
Bartter Syndrome - Pulmonology Advisor
Bartter syndrome is a clinical condition associated with chronic metabolic alkalosis and hypokalemia. As opposed to Gitelman syndrome, Bartter syndrome has a normal serum magnesium (see section on Gitelman syndrome). The age of onset of clinical symptoms is within the first few years of life with the findings of polyuria and polydipsia, frequent dehydration, muscle cramps, and weakness. These patients often have salt craving to help replete intravascular volume. This is a genetic, recessive disorder and can be diagnosed prenatally.. This may be mistaken as familial hypokalemic paralysis (FHP), which is an autosomal dominant disease. FHP has intermittent hypokalemia with normal urinary potassium and normal total body potassium stores. ...

Membrane Ion Transport in Bartters Syndrome | Hypertension
Increased permeability of the cell membranes for Na+, usually measured in red blood cells, is a well-known phenomenon in Bartters syndrome.16-18 The degree of Na+ permeability differs between the patients with Bart-ters syndrome (Table 2⇑), as do Na+,K+,2Cl− antiport and calcium-dependent K+ permeability. Thus, a conclusion of heterogeneity of the Bartters syndrome (or Bartter-like syndromes) could be made. Indeed, even a preliminary analysis dissects Bartters syndrome into at least three different entities: (1) a type with hypercalciuria, normomagnesemia, increased cAMP-dependent NHE, nearly absent Na+,K+,2Cl− cotransport, increased calcium-activated K+ permeability, and a good effect of nonsteroidal anti-inflammatory drugs in the past (patients A through D, classic Bartters syndrome)1-4; (2) a type without calciuria, with hypomagnesemia, calmodulin-dependent enhancement of NHE, normal or increased Na+,K+,2Cl− cotransport, high calcium-dependent K+ permeability, and no effect of ...

Bartter syndrome: An infrequent tubulopathy of prenatal onset
Under physiological conditions, the ions reabsorp tion in the TALH is an extremely complex process that requires indemnity of the different channels and co transporters in the tubular cell. Any defect in any of them causes renal loss of sodium, chlorine, potassium, and calcium that will try to compensate in other seg ments of the tubule. The earliest manifestation of this tubular dysfunction is fetal polyuria, which leads in the last trimester of pregnancy to the development of seve re polyhydramnios.. Antenatal diagnosis is possible through documen tation of elevated chlorine levels in amniotic fluid and genetic study15.. The direct consequence of the molecular defect in the TALH is a reabsorption failure of filtered sodium. The high amount of sodium reaching the distal ne phron of the tubules exceeds the possibility of com pensation for the distal convoluted tubule and the collecting ducts causing sodium loss. The chronic loss of sodium leads to contraction of the extracellular vo lume and ...

Altered Systemic Hemodynamic and Baroreflex Response to Angiotensin II in Postural Tachycardia SyndromeClinical Perspective |...
The dose of Ang II used in this study produced a mild, but immediate response in the systemic vasculature, renal vasculature, and adrenal gland. The use of Ang II infusion at a physiological dose systemically provides a powerful and reproducible method of directly assessing the vascular response in vivo.21 In the present study, we demonstrated for the first time to our knowledge an attenuated systemic vascular response to Ang II infusion in POTS. This was evidenced by the significant smaller increment in mean arterial pressure in patients with POTS compared to healthy controls. The impaired vascular response in POTS may be related to the elevated level of circulating plasma Ang II that we and others have previously described in this population.10,11 The prolonged presence of high levels of Ang II have been shown to induce a state of relative vascular resistance to the pressor effect of Ang II22 in conditions such as Bartter syndrome, cirrhosis, and pregnancy.23-25 Furthermore, low sodium intake, ...

Certainly when the almost urine got to distal tubule 85% of the water had been already reabsorbed and all that had to be done was to finish up this process. In fact only 1% was supposed to go beyond the rather uniform looking cells of the distal tubule.. Gradually, however, our views began to change and through the advances in physiology, biochemistry and histology a different picture began to emerge. Nobody could have dreamed of the variety of cells in both the distal tubule and the collecting system. In a healthy person or animal, things seemed simple indeed, but let a defect or two creep in and then we begin to see the dragons.. We already understand quite a bit about what can happen. If we go back one page (to page 11) we note that the very first part of the distal tubule has cells with the characteristics of those of the thick ascending loop of Henle. These cells are marked in yellow and include the macula densa. A defect in these cells leads to Bartter s syndrome.. Next, come the cells (in ...

Gitelman syndrome - Wikipedia
Gitelman syndrome is an autosomal recessive kidney disorder characterized by low blood levels of potassium and magnesium, decreased excretion of calcium in the urine, and elevated blood pH. The disorder is caused by genetic mutations resulting in improper function of the thiazide-sensitive sodium-chloride symporter (also known as NCC, NCCT, or TSC) located in the distal convoluted tubule of the kidney. This symporter is a channel responsible for the transport of multiple electrolytes such as sodium, chloride, calcium, magnesium, and potassium. Gitelman syndrome was formerly considered a subset of Bartter syndrome until the distinct genetic and molecular bases of these disorders were identified. Bartter syndrome is also an autosomal recessive hypokalemic metabolic alkalosis, but it derives from a mutation to the NKCC2 found in the thick ascending limb of the loop of Henle. Affected individuals may not have symptoms in some cases. Symptomatic individuals present with symptoms identical to those of ...
KCNJ1 gene - Genetics Home Reference
Several dozen mutations in the KCNJ1 gene have been identified in people with Bartter syndrome type II. This form of the disorder causes severe or life-threatening health problems that become apparent before or soon after birth.. Some of the KCNJ1 gene mutations responsible for Bartter syndrome change single protein building blocks (amino acids) in the ROMK protein. These mutations prevent the protein from reaching the cell membrane or alter the channels ability to transport potassium ions. Other mutations in the KCNJ1 gene delete amino acids from the protein or lead to the production of an abnormally short, nonfunctional version of ROMK.. A loss of functional ROMK affects the normal activity of the NKCC2 protein, preventing it from transporting ions into kidney cells. As a result, the kidneys cannot reabsorb salt normally and excess salt is lost through the urine (salt wasting). The abnormal salt loss disrupts the normal balance of sodium, potassium, and other ions in the body. These ...

Rho Kinase Inhibition and Vascular Protection: Support From Studies in Bartter and Gitelman Syndrome | Arteriosclerosis,...
To the Editor:. In a recent article, Wolfrum et al1 have shown that in human cells in culture, inhibition of Rho kinase (RKO) activates Akt pathway, which they contend leads to cardiovascular protection via activation of eNOS. ROK (a downstream effector of RhoA G protein) involvement has been advanced in the pathogenesis of hypertension and atherosclerosis.2 This is based on its modulation of regulatory chain phosphorylation of myosin II which contributes to smooth muscle Ca2+ sensitization,3 increased expression of NAD(P)H oxidase,4 and induction of oxidative stress.. We would like to suggest that recent results from our ongoing studies in patients with Bartter and Gitelman syndrome (BS/GS)5 provide additional support for Wolfrum and colleagues conclusions as well as additional evidence for the importance of ROK in cardiovascular protection. Of direct relevance to the report of Wolfrum and coworkers1 is our recent demonstration in BS/GS patients that RhoA/Rho Kinase pathway is blunted6 and ...
Because a great many of the symptoms and signs of both Bartter s and Gitelman s syndromes are due to the overproduction of renin in the juxtaglomerular cells (JG cells) a more in depth study of the renin-angiotensin-aldosterone system must be made. Before going on with this it was decided to root out the old slides and pictures in the cellar and have a holiday looking at juxtaglomerular cells. It is doubtful if similar slides are made today because when these were made over forty years ago Bartter s syndrome had just been discovered and the discovery of Gitelman s syndrome was in the future. There was consequently no treatment for Bartter s syndrome beyond replacing potassium and the use of spironolactone. It proved to be no holiday and the slides were full of dust and heaven knows what. This recent diagram is included for orientation:. ...

Retina & Macula Specialists December 2016 - Retina & Macula Specialists
Sclerochoroidal calcification is an uncommon benign condition characterised by yellow-white subretinal masses that typically lie along the superotemporal vascular arcades in elderly Caucasian patients.1 Histopathologically, the lesions represent deposition of calcium pyrophosphate in the sclera and/or choroid.2 It is hypothesised that their superotemporal location may be related to the insertion of the superior oblique muscle.. Most cases of sclerochoroidal calcification are idiopathic, however occasionally there may be an underlying systemic cause such as hypercalcemia, hyperparathyroidism or hypomagnesemia. For this reason, baseline blood tests should be checked. The condition has been associated with renal tubular hypokalemic metabolic alkalosis syndromes including Bartter and Gitelman syndromes.1 Imaging features have been described by Fung et. al.3 These include fundus hyperautofluorescence and a rocky configuration on enhanced-depth imaging optical coherence tomography (EDI-OCT). The ...
Clinical presentation of genetically defined patients with hypokalemic salt-losing tubulopathies
ROMK, NKCC2, and NCCT mutations usually have uniform clinical presentations, whereas mutations in ClC-Kb occasionally lead to phenotypic overlaps with the NCCT or, less commonly, with the ROMK/NKCC2 cohort. Based on these results, we propose an algorithm for the molecular diagnosis of hypokalemic sa …

Association analysis between hypertension and CYBA, CLCNKB, and KCNMB1 functional polymorphisms in the Japanese population--the...
BACKGROUND Reproducibility of results is important for the validity of genetic association studies. Recently, 3 functional polymorphisms, G(-930)A in CYBA, T481S in CLCNKB, and E65K in KCNMB1, were reported to be associated with blood pressure (BP) status and the aim of this study was to confirm those findings using a large cohort representing the general Japanese population. METHODS AND RESULTS The study population consisted of 3,652 subjects recruited from the Suita study as representative of the general population in Japan. The genotypes of the 3 polymorphisms were determined by the TaqMan method. Logistic analysis indicated that the CYBA/G(-930)A polymorphism was associated with hypertension in male subjects. In the male population, the odds ratio of the GG genotype over GA + AA was 1.27 (95% confidence interval 1.01-1.57, p=0.034). Moreover, residuals of systolic and diastolic BP values were significantly higher in subjects with the GG genotype than in those with the GA or AA genotype (p=0.0007).

Our patient, a 31-year old, previously healthy Caucasian Swiss man, had a case of impressive symptomatic hypokalemia. His neurological symptoms (cramping and muscle weakness) resolved rapidly after correction of hypokalemia.. Hypokalemic paresis (paralysis) may be acquired in patients with thyrotoxicosis . Our patient showed neither clinical nor biochemical signs of this disease, which is mainly found in Asians but still is more common as a cause of severe neurological symptoms in a patient presenting with hypokalemia in our hospital than Gitelmans syndrome, with the latter being more commonly found by chance on the basis of a laboratory finding of low potassium. Our patient had no history suggestive of familial periodic paralysis. This rare, hereditary defect of calcium or magnesium channels in skeletal muscles enhances the likelihood that insulin secreted after the intake of carbohydrate-rich food or catecholamine bursts (in response to stress or exertion) will result in increased ...

Liddle syndrome (LS) is a familial disease characterized by early onset hypertension (HT). Although regarded as rare, its incidence may be greater than expected because the classical findings of hypokalemic metabolic alkalosis with suppressed renin and aldosterone levels are not consistently present. Herein, we present the case of an adolescent boy and maternal relatives who were followed up with misdiagnosis of essential HT for a long duration. Clinical diagnosis of LS was confirmed on genetic analysis. Despite carrying the same mutation, the index patient and the family members manifested heterogeneous phenotypes of the disease including age at presentation, degree of HT, presence of hypokalemia and renal/cardiac complications ...
Magnesium lactate in the treatment of Gitelman syndrome: patient-reported outcomes. - Jost Chemical Co.
Abstract:. BACKGROUND: Gitelman syndrome (GS) is a rare recessively inherited renal tubulopathy associated with renal potassium (K) and magnesium (Mg) loss. It requires lifelong K and Mg supplementation at high doses that are at best unpalatable and at worst, intolerable. In particular, gastrointestinal side effects often limit full therapeutic usage.. METHODS: We report here the analysis of a cohort of 28 adult patients with genetically proven GS who attend our specialist tubular disorders clinic, in whom we initiated the use of a modified-release Mg preparation (slow-release Mg lactate) and who were surveyed by questionnaire.. RESULTS: Twenty-five patients (89%) preferred the new treatment regimen. Of these 25, 17 (68%) regarded their symptom burden as improved and seven reported no worsening. Of the 25 who were not Mg-treatment naïve, 13 (59%) patients reported fewer side effects, 7 (32%) described them as the same and only 2 (9%) considered side effects to be worse. Five were able to ...
ECG Changes with Hypo-/Hyperkalemia | Anesthesia Board Review Courses | Anesthesiology Consultants
The resting membrane potential (RMP) of myocytes is determined by the Na+/K+-ATPase, which pumps 3 Na+ out for every 2K+ pumped and an open potassium channel that allows K to move outside the cell, down its concentration gradient. Both these events produce a negative intracellular change and a negative RMP. Since the potassium channel is the open at rest, changes in the internal or external K concentration may change the RMP according to the equation:. ERMP ≈ E = -[RT/F] ln [K+]I/ [K+]o. Thus, hypokalemia lowers the RMP, making it harder to achieve threshold for depolarization and hyperkalemia raises the RMP, making it easier to achieve threshold.. Causes of hypokalemia include inadequate intake, loss, or redistribution. Causes of loss can be: (1) GI: Diarrhea, (2) Skin: Sweating, (3) Renal: Lasix, HCTZ, Amphotericine, Cisplatin, Hyperaldosteronism, Cushings disease, Bartter sundrome. Causes of redistribution (entry into cells) include β-agonists, insulin, Hypokalemic per ...
The CLC family of chloride channels and transporters is made up - GLO1 inhibitors for neuropsychiatric
The CLC family of chloride channels and transporters is made up by nine members but just three of these ClC-Ka/b ClC-7 and ClC-2 have already been found up to now connected with auxiliary subunits. immunoglobulin (Ig)-like domains regulates its subcellular localization and activity in glial cells. The normal theme for these three proteins can be their requirement of an effective homeostasis since their breakdown leads to specific illnesses. We will review right here their properties and their part in regular chloride physiology as well as the pathological outcomes of their incorrect function. Intro Chloride is very important to many biological features such Apremilast as for example transepithelial fluid transportation acidification of intracellular organelles muscle tissue contraction neuronal membrane potential or cell quantity rules.

Gitelmans Syndrome, need advise - Rare Disases - Condition | Our Health
Hi, I was diagnosed with gitelman sydrome when I was 7 years old and I am now 19 years old. It has been so long that I have somewhat gotten used to feeling crappy, I really resent taking my medication just because its such a nuisance to have to take it so often and its almost easier to stay at a lower level than go up and keep up there. So yeah I feel sick sometimes and I have a good amount of symptoms but I dont have anything to compare it too so I dont really know. All my parents say and all the doctors say is take your medications but why? I dont even think taking them more often would change much plus sometimes I get really shaky and anxious from taking them. One time I took my medication all at once plus some pain killers for a headace and my body was shaking for 20 minutes and I had to lie down because I was so dizzy. I have had several doctors over the years but none of them have really known much of anything, even the one at childrens hospital in vancouver. So I have a lot of ...
