    A pre-term baby girl was born following a pregnancy complicated by severe polyhydramnios at a gestational age of 36 weeks. She was initially suffering from respiratory distress consistent with idiopathic respiratory distress syndrome, and altered electrolyte imbalance with hyponatremia, hypokalemia and hypochloremic metabolic alkalosis. However, during the third week of life when she had dehydration along with significant electrolyte imbalance, Bartter's syndrome was considered which was supported by findings of high renin and aldosterone levels. Treatment was done by correction of electrolytes and dehydration along with indomethacin. The drug was well tolerated. The infant showed correction of electrolyte imbalance. The features of this case suggest an extreme form of Bartter's syndrome presenting from the early days of life. The syndrome is reported because of it's rarity and alerts pediatricians to the antenatal and neonatal variant of Bartter's syndrome. (author)

    Antenatal Bartter syndrome is characterized by severe polyhydramnios in mother leading to premature delivery. Antenatal treatment has proven effective to prevent these problems. Postnatally newborns suffer from recurrent episodes of severe dehydration and electrolyte imbalance which can lead to fatal outcome. These manifestations are likely to be overlooked and missed under the umbrella of diagnosis of prematurity. This premature newborn with antenatal polyhydramnios had severe manifestations of polyuria, recurrent dehydration, electrolyte derangements and metabolic alkalosis. She was managed accordingly but unfortunately could not survive beyond 4 weeks.

    2016-01-01

    Bartter syndrome is a rare heterogeneous group of autosomal-recessive salt-losing renal tubular disorders that can present in fetal life (antenatal Bartter syndrome; ABS) as "unexplained" early-onset polyhydramnios, often associated with growth restriction. Prenatal diagnosis of the condition involves assessment of amniotic fluid biochemistry in a setting of polyuric polyhydramnios; with elevated chloride levels considered a consistent and diagnostic finding. Other amniotic fluid biochemical markers have been described, notably increased aldosterone levels, and low total protein levels. NOVEL INSIGHT: Antenatal Bartter syndrome is a heterogeneous group of renal disorders. While certain biochemical features in amniotic fluid might heighten suspicion, final diagnosis can only be made in the postnatal setting. In the setting of unexplained severe polyhydramnios, clinicians should continue to entertain the diagnosis of antenatal Bartter Syndrome and maintain neonatal surveillance, even if amniotic fluid markers do not support the diagnosis.

    Bartter syndrome represents the group of renal disturbances characterized by hypokaliemia and metabolic alkalosis. Some diseases could display hypokalemic metabolic alkalosis without primary tubular dysfunction. These disorders are called pseudo-Bartter syndrome. In this paper we present 2 cases of pseudo-Bartter syndrome related among to other things to overuse of diuretic drugs.

    2012-02-01

    We aim to review the clinical features of two renal tubular disorders characterized by sodium and potassium wasting: Bartter syndrome and Gitelman syndrome. Selected key references concerning these syndromes were analyzed, together with a PubMed search of the literature from 2000 to 2011. The clinical features common to both conditions and those which are distinct to each syndrome were presented. The new findings on the genetics of the five types of Bartter syndrome and the discrete mutations in Gitelman syndrome were reviewed, together with the diagnostic workup and treatment for each condition. Patients with Bartter syndrome types 1, 2 and 4 present at a younger age than classic Bartter syndrome type 3. They present with symptoms, often quite severe in the neonatal period. Patients with classic Bartter syndrome type 3 present later in life and may be sporadically asymptomatic or mildly symptomatic. The severe, steady-state hypokalemia in Bartter syndrome and Gitelman syndrome may abruptly become life-threatening under certain aggravating conditions. Clinicians need to be cognizant of such renal tubular disorders, and promptly treat at-risk patients.

    Bartter syndrome is a group of inherited, salt-losing tubulopathies presenting as hypokalemic metabolic alkalosis with normotensive hyperreninemia and hyperaldosteronism. Around 150 cases have been reported in literature till now. Mutations leading to salt losing tubulopathies are not routinely tested in Indian population. The authors have done the genetic analysis for the first time in the Bartter syndrome on two cases from India. First case was antenatal Bartter syndrome presenting with massive polyuria and hyperkalemia. Mutational analysis revealed compound heterozygous mutations in KCNJ1(ROMK) gene [p(Leu220Phe), p(Thr191Pro)]. Second case had a phenotypic presentation of classical Bartter syndrome however, genetic analysis revealed only heterozygous novel mutation in SLC12A gene p(Ala232Thr). Bartter syndrome is a clinical diagnosis and genetic analysis is recommended for prognostication and genetic counseling.

    Bartter's syndrome is characterized by generalized hyperplasia of juxtaglomerular apparatus, hyperreninism leading to secondary hyperaldesteronism, hypokalemic alkalosis and normal blood pressure. Although nephrocalcinosis has been described sporadically in patients with Barter's syndrome, this is still generally unrecognized. We reported a case of Barter's syndrome with nephrocalcinosis and discussed clinical significance of nephrocalcinosis in this syndrome.

    Bartter syndrome is a rare inherited defect in the thick ascending limb of the loop of Henle. It is characterized by low potassium levels (hypokalaemia), increased blood pH (alkalosis) and normal to low blood pressure. There are three types of Bartter syndrome: neonatal, the classic type and Gitelman syndrome. Nephropathic cystinosis is an autosomal recessive disorder characterized by accumulation of free cystine in lysosomes due to disorder of lysosomal transport that can lead to end stage renal failure within 10 years and multiorgan impairment. We report a 5 year 9 month old child with Bartter syndrome associated with nephropathic cystinosis, hypothyroidism and rickets. Hitherto, only a handful of similar cases have been reported in the literature.

    2012-01-01

    Full Text Available Antenatal Bartter syndrome (ABS is a rare autosomal recessive renal tubular disorder. The defective chloride transport in the loop of Henle leads to fetal polyuria resulting in severe hydramnios and premature delivery. Early onset, unexplained maternal polyhydramnios often challenges the treating obstetrician. Increasing polyhydramnios without apparent fetal or placental abnormalities should lead to the suspicion of this entity. Biochemical analysis of amniotic fluid is suggested as elevated chloride level is usually diagnostic. Awareness, early recognition, maternal treatment with indomethacin, and amniocentesis allow the pregnancy to continue. Affected neonates are usually born premature, have postnatal polyuria, vomiting, failure to thrive, hypercalciuria, and subsequently nephrocalcinosis. Hypokalemia, metabolic alkalosis, secondary hyperaldosteronism and hyperreninaemia are other characteristic features. Volume depletion due to excessive salt and water loss on long term stimulates renin-angiotensin-aldosterone system resulting in juxtaglomerular hyperplasia. Clinical features and electrolyte abnormalities may also depend on the subtype of the syndrome. Prenatal diagnosis and timely indomethacin administration prevent electrolyte imbalance, restitute normal growth, and improve activity. In this paper, authors present classification, pathophysiology, clinical manifestations, laboratory findings, complications, and prognosis of ABS.

    Pseudo-Bartter Syndrome is a rare medical disease of the kidney characterized by normal blood pressure, hypokalemic metabolic alkalosis, hyperreninemia and hyperaldosteronism with drug history of diuretics. We report US, CT and MRI findings of a patients with clinically proved Pseudo-Bartter syndrome. The patient was a 37 year old woman with a history of long term ingestion of the diuretics(furosemide) for 20 years. Renal US revealed hyperechoic renal medulla at both kidneys. The resistive index(RI), calculated from the duplex doppler waveform is 0.61. Unenhanced CT revealed faint high attenuation along the medulla. T1-weighted MRI revealed indistinct corticomedullary differentiation.

    Bartter syndrome consists a group of rare autosomal-recessive renal tubulopathies characterised by renal salt wasting, hypokalaemic metabolic alkalosis, hypercalciuria and hyperreninaemic hyperaldosteronism. It is classified into five types. Mutations in the KCNJ1 gene (classified as type II) usually cause the neonatal form of Bartter syndrome. We describe an adult patient with a homozygous KCNJ1 mutation resulting in a remarkably mild phenotype of neonatal type Bartter syndrome.

    2009-02-01

    Full Text Available We report a rare case of Bartter's syndrome in a 35-year-old woman with type 2 diabetes mellitus. The patient presented with leg weakness, fatigue, polyuria and polydipsia. Hypokalemia, metabolic alkalosis, and high renin and aldosterone concentrations were present, but the patient was normotensive. Gitelman's syndrome was excluded because of the presence of hypercalciuria, secondary hyperparathyroidism and bilateral nephrocalcinosis. The patient's condition improved upon administration of a prostaglandin synthetase inhibitor (acemetacin, oral potassium chloride and potassium-sparing diuretics. Five months later, the patient discontinued acemetacin because of epigastric discomfort; at the same time, severe hypokalemia and hyperglycemia developed. Glucagon stimulation and water deprivation tests were performed. Type 2 diabetes mellitus with nephrogenic diabetes insipidus was diagnosed. To avoid further gastrointestinal complications, the patient was treated with celecoxib, a selective cyclooxygenase 2 inhibitor. This case serves as a reminder that Bartter's syndrome is associated with various metabolic derangements including nephrogenic diabetes insipidus, nephrocalcinosis and diabetes mellitus. When treating Bartter's syndrome, it is also prudent to remember that the long-term use of nonsteroidal anti-inflammatory drugs and potassium-sparing diuretics may result in serious adverse reactions.

    Bartter syndrome is a severe inherited tubulopathy responsible for renal salt wasting, and hence electrolyte disorders and dehydration. Prenatally, it is characterized by severe polyhydramnios caused by fetal polyuria. We studied for the first time fetal urine in a Bartter syndrome case and demonstrated that the tubulopathy is already present at 24 weeks of gestation.

    Bartter syndrome (BS) is clinically classified into antenatal or neonatal BS (aBS) and classic BS (cBS) as well as five subtypes based on the underlying mutant gene; SLC12A1 (BS I), KCNJ1 (BS II), CLCNKB (BS III), BSND (BS IV) and CASR (BS V). Clinico-genetic features of a nationwide cohort of 26 Korean children with BS were investigated. The clinical diagnosis was aBS in 8 (30.8%), cBS in 15 (57.7%) and mixed Bartter-Gitelman phenotype in 3 cases (11.5%). Five of eight patients with aBS and all 18 patients with either cBS or mixed Bartter-Gitelman phenotype had CLCNKB mutations. Among the 23 patients (46 alleles) with CLCNKB mutations, p.W610X and large deletions were detected in 25 (54.3%) and 10 (21.7%) alleles, respectively. There was no genotype-phenotype correlation in patients with CLCNKB mutations. Twenty-three (88.5%) of the 26 BS patients involved in this study had CLCNKB mutations. The p.W610X mutation and large deletion were two common types of mutations in CLCNKB. The clinical manifestations of BS III were heterogeneous without a genotype-phenotype correlation, typically manifesting cBS phenotype but also aBS or mixed Bartter-Gitelman phenotypes. The molecular diagnostic steps for patients with BS in our population should be designed taking these peculiar genotype distributions into consideration, and a new more clinically relevant classification including BS and Gitelman syndrome is required.

    Bartter syndrome is an autosomic recessive disease characterized by severe polyuria and sodium renal loss. The responsible genes encode proteins involved in electrolyte tubular reabsorption. Prenatal manifestations, mainly recurrent polyhydramnios because of fetal polyuria, lead to premature delivery. After birth, polyuria leads to life-threatening dehydration. Prenatal genetic diagnosis needs an index case. The aim of this study was to analyze amniotic fluid biochemistry for the prediction of Bartter syndrome. We retrospectively studied 16 amniotic fluids of Bartter syndrome-affected fetuses diagnosed after birth, only six of them being genetically proven. We assayed total proteins, alpha-fetoprotein, and electrolytes and defined a Bartter index corresponding to the multiplication of total protein and of alpha-fetoprotein. Results were compared with two control groups matched for gestational age-non-Bartter polyhydramnios (n = 30) and nonpolyhydramnios (n = 60). In Bartter syndrome, we observed significant differences (p Bartter index (0.16, 0.82, and 1.0, respectively). No statistical difference was observed for electrolytes. In conclusion, Bartter syndrome can be prenatally suspected on amniotic fluid biochemistry (sensitivity 93% and specificity 100%), allowing appropriate management before and after birth.

    Bartter syndrome is a rare autosomal recessive disorder characterized by hypokalemia, salt loss, and metabolic alkalosis. Short stature is one of the clinical manifestations in these children. Although polyuria, polydipsia, hypokalemia, and salt loss may be responsible for growth retardation, the exact pathogenesis of short stature in Bartter syndrome is not known. In this study, we present three children diagnosed as having Bartter syndrome with short stature and growth hormone (GH) deficiency. After recombinant human growth hormone therapy (rhGH), their growth velocities were improved. These results indicate that GH deficiency may contribute to short stature in children with Bartter syndrome, and rhGH therapy would be an excellent adjunctive treatment for short children with this syndrome whose condition is resistant to conventional therapies in terms of growth.

    A five-year-old boy was referred to our pediatric clinic for evaluation of failure to thrive, headache, intermittent high fever, restlessness, polyuria, and polydipsia. His weight and height measurements were under the 3rd percentile. Clinical findings consisted of frontal bossing, carious teeth, O-bain deformity of the lower extremities, and moderate dehydration. The presence of metabolic alkalosis, hypokalemia, hypochloremia, and high renin and aldosterone levels were suggestive of Bartter syndrome and a treatment regimen for Bartter syndrome was started. At follow-up, the polyuria and hyponatremia were found to persist. A reassessment of the patient revealed findings consistent with proximal renal tubular acidosis such as metabolic acidosis with a high urinary pH, proteinuria, aminoaciduria with phosphaturia and hypercalciuria. Based on the presence of parental consanguinity as well as polyuria, proteinuria, low tubular reabsorption of phosphorus, generalized aminoaciduria, light yellow skin and hair color, the probable diagnosis of cystinosis was established and was confirmed by slit-lamp examination of the cornea showing cystine crystal deposition. Our case is a good example demonstrating that development of metabolic alkalosis does not exclude cystinosis and that all findings of the patient should be thoroughly evaluated. ©Journal of Clinical Research in Pediatric Endocrinology, Published by Galenos Publishing.

    Mutations in the MAGED2 gene, located on the X chromosome, have been recently detected in males with a transient form of antenatal Bartter syndrome or with idiopathic polyhydramnios. The aim of this study is to analyze the proportion of the population with mutations in this gene in a French cohort of patients with antenatal Bartter syndrome. The French cohort of patients with antenatal Bartter syndrome encompasses 171 families. Mutations in genes responsible for types 1-4 have been detected in 75% of cases. In patients without identified genetic cause ( n =42), transient antenatal Bartter syndrome was reported in 12 cases. We analyzed the MAGED2 gene in the entire cohort of negative cases by Sanger sequencing and retrospectively collected clinical data regarding pregnancy as well as the postnatal outcome for positive cases. We detected mutations in MAGED2 in 17 patients, including the 12 with transient antenatal Bartter syndrome, from 16 families. Fifteen different mutations were detected (one whole deletion, three frameshift, three splicing, three nonsense, two inframe deletions, and three missense); 13 of these mutations had not been previously described. Interestingly, two patients are females; in one of these patients our data are consistent with selective inactivation of chromosome X explaining the severity. The phenotypic presentation in our patients was variable and less severe than that of the originally described cases. MAGED2 mutations explained 9% of cases of antenatal Bartter syndrome in a French cohort, and accounted for 38% of patients without other characterized mutations and for 44% of male probands of negative cases. Our study confirmed previously published data and showed that females can be affected. As a result, this gene must be included in the screening of the most severe clinical form of Bartter syndrome.

    Bartter patients may be hypercalciuric. Additional abnormalities in the metabolism of calcium, phosphate, and calciotropic hormones have occasionally been reported. The metabolism of calcium, phosphate, and calciotropic hormones was investigated in 15 patients with Bartter syndrome and 15 healthy subjects. Compared to the controls, Bartter patients had significantly reduced plasma phosphate {mean [interquartile range]:1.29 [1.16-1.46] vs. 1.61 [1.54-1.67] mmol/L} and maximal tubular phosphate reabsorption (1.16 [1.00-1.35] vs. 1.41 [1.37-1.47] mmol/L) and significantly increased parathyroid hormone (PTH) level (6.1 [4.5-7.7] vs. 2.8 [2.2-4.4] pmol/L). However, patients and controls did not differ in blood calcium, 25-hydroxyvitamin D, alkaline phosphatase, and osteocalcin levels. In patients, an inverse correlation (P Bartter patients.

    To summarize the clinical characteristics of Bartter syndrome and investigate its pathogenesis. The clinical data of 6 cases of Bartter syndrome at our hospital from November 2006 to May 2010 were analyzed retrospectively. The onset age of Bartter syndrome was 13-35 years old. The main symptoms included weakness (6/6), paralysis (1/6), numbness (5/6) and tetany (4/6). All patients had normal blood pressure. The biochemical tests showed persistent hypokalemia, metabolic alkalosis (6/6) and hyperreninemia. The pathological examination of deltoid muscle biopsy showed the swelling, degeneration and necrosis of myocytes and the deposition of immunocomplex in myolemma. And the pathological examination of renal biopsy showed the hyperplasia of juxtaglomerular apparatus (5/6) and the deposition of immunocomplex. All symptoms were relieved after a therapy of potassium supplementation or a combination of indomethacin, spironolactone and immunosuppressant. When such clinical features as weakness, paralysis, tetany, hypokalemic alkalosis and normotension are encountered, Bartter syndrome should be suspected. Serum electrolytes, blood gas analysis and activation of the renin-angiotensin-aldosterone system should be examined for a definite diagnosis. The treatment of choice includes potassium and magnesium supplementation or in combination with prostaglandin synthetase inhibitor, aldosterone antagonist and immunosuppressant. Immunologic mechanism may participate in the course of Bartter syndrome.

    Bartter syndrome is a severe inherited tubulopathy characterized at birth by salt wasting, severe polyuria, dehydration, growth retardation and secondary hyperaldosteronism. Prenatally, the disease is usually discovered following onset of severe polyhydramnios. We studied amniotic fluid aldosterone concentration in cases of Bartter syndrome and in control groups. Amniotic fluid aldosterone was assayed by radioimmunoassay. We undertook a retrospective case-control study based on 36 cases of postnatally diagnosed Bartter syndrome and 144 controls matched for gestational age. Two controls groups were defined: controls with polyhydramnios (n=72) and control without polyhydramnios (n=72). Amniotic fluid aldosterone was compared between the three groups. The median amniotic fluid aldosterone concentration in the Bartter syndrome group (90 pg/mL) did not differ significantly from that in the controls with polyhydramnios (90 pg/mL, p=0.33) or the controls without polyhydramnios (87 pg/mL, p=0.41). In conclusion, amniotic fluid aldosterone assay cannot be used for prenatal diagnosis of Bartter syndrome.

    Cystinosis is a rare autosomal recessive disorder resulting from defective lysosomal transport of cystine due to mutations in the cystinosin lysosomal cystine transporter (CTNS) gene. The clinical phenotype of nephropathic cystinosis is characterized by renal tubular Fanconi syndrome and development of end-stage renal disease during the first decade. Although metabolic acidosis is the classically prominent finding of the disease, a few cases may present with hypokalemic metabolic alkalosis mimicking Bartter syndrome. Bartter-like presentation may lead to delay in diagnosis and initiation of specific treatment for cystinosis. We report a case of a 6-year-old girl initially presenting with the features of Bartter syndrome that was diagnosed 2 years later with nephropathic cystinosis and a novel CTNS mutation.

    Bartter syndrome type IV, also known as Bartter syndrome with sensorineural deafness (BSND), is caused by loss-of-function mutations in the BSND gene, which encodes barttin, an accessory subunit of chloride channels located in the kidney and inner ear. Patients with BS IV have a highly variable clinical phenotype. This report concerns a Korean male patient with antenatal Bartter syndrome due to a homozygous BSND p.G47R mutation, who presented with severe perinatal symptoms followed by a relatively benign course with preserved renal function after early infancy. In addition, the clinical features and the laboratory data of the patient were compared with those of previously reported patients with the same mutation.

    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.

    Pseudo-Bartter syndrome (PBS) describes an uncommon but well recognised complication of cystic fibrosis leading to hypochloraemic, hypokalaemic metabolic alkalosis. Pseudo-Bartter syndrome is usually seen at initial presentation or within the first two years of life in children with cystic fibrosis. Risk factors for development of PBS include warm weather conditions, severe respiratory or pancreatic disease and gastrointestinal losses (e.g. vomiting and diarrhoea). PBS is rare in older children and adolescents although epidemics have been associated with heat wave conditions in warmer climates. In this era of climate change, it is crucial that clinicians consider Pseudo-Bartter syndrome when patients with cystic fibrosis present unwell during summer. Copyright © 2014 Elsevier Ltd.

    Mutations in the ROMK1 potassium channel gene ( KCNJ1 ) cause antenatal/neonatal Bartter syndrome type II (aBS II), a renal disorder that begins in utero , 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 KCNJ1 missense mutations, consisting of a novel c.197T > A (p.I66N) and a previously reported c.875G > A (p.R292Q) KCNJ1 mutation. We implemented and evaluated the performance of two different bioinformatics-based approaches of targeted massively parallel sequencing [next generation sequencing (NGS)] in defining the molecular diagnosis. Our results demonstrate that aBS II may be suspected in patients with a late-onset phenotype. Our experimental approach of NGS-based mutation screening combined with Sanger sequencing proved to be a reliable molecular approach for defining the clinical diagnosis in our patient, and results in important differential diagnostic and therapeutic implications for patients with BS. Our results could have a significant impact on the diagnosis and methodological approaches of genetic testing in other patients with clinical unclassified phenotypes of nephrocalcinosis and congenital renal electrolyte abnormalities.

    Maternal transfer of heavy metals during fetal development or lactation possibly contributed to the clinical manifestations of Bartter syndrome and developmental delay in the offspring. An 11-month-old child diagnosed with Bartter syndrome and failure to thrive was treated concurrently for elevated metal burden while he was undergoing standard medical interventions. Treatment with body-weight doses of meso-2,3-dimercaptosuccinic acid (DMSA) reduced the body burden of lead, beryllium, copper, mercury, and cadmium at the three- and sixth-month follow-up tests. During the course of the six-month treatment, the patient gained 2.4 kg (5.2 lb) and grew approximately 9.5 cm (3.75 in). His weight shifted from significantly below the 5th percentile in weight to within the 5th percentile, and from below the 5th to within the 10th percentile for length. The child's acquisition of lead, beryllium, and copper correspond to his mother's history of stained glass assembly and occurred during fetal development or lactation, since there were no other identifiable sources that could have contributed to the heavy metal burden. Tests for known genetic mutations leading to Bartter syndrome were all negative. This case report highlights the potential benefit of DMSA for treatment of heavy metal body burden in infants who present with Bartter syndrome.

    Bartter syndrome, a group of disorders that encompasses multiple genetic defects with similar clinical presentation, has been divided into six different genotypes, according to different genetic defects, and into three main clinical variants (or phenotypes). Classic laboratory findings in all variants include hypochloremia, hypokalemia, and metabolic alkalosis with excessive excretion of chloride and potassium. Classic Bartter syndrome, neonatal Bartter syndrome, and Gitelman syndrome are the three main clinical variants. Classic Bartter syndrome and neonatal Bartter syndrome have defects in genes that affect transport channels in the ascending loop of Henle, where as in Gitleman syndrome the defect occurs in the transport channels of the distal convoluted tubule. Classic Bartter syndrome and neonatal Bartter syndrome have similar presenting symptoms, potential outcomes, and treatment, but different ages at presentation. Gitelman syndrome, a more benign condition than the other clinical variants, has the classic hallmark finding of hypomagnesemia and low to normal excretion of calcium. This differentiates it from the classic and neonatal variants of the disease. With early diagnosis and proper treatment, Bartter syndrome has a good prognosis. But failure to identify it can lead to tubulointerstitial nephritis and renal failure. We present a case of a 6-month-old boy with Bartter syndrome who presented with poor weight gain and an abdominal mass.

    Bartter syndrome (BS) may be associated with different degrees of hypercalciuria, but marked parathyroid hormone (PTH) abnormalities have not been described. We compared clinical and laboratory data of patients with either ROMK-deficient type II BS (n = 14) or Barttin-deficient type IV BS (n = 20). Only BS-IV patients remained mildly hypokalemic in spite of a higher need for potassium supplementation. Estimated glomerular filtration rate (eGFR) was mildly decreased in only four BS-IV patients. Average PTH values were significantly higher in BS-II (160.6 ± 85.8 vs. 92.5 ± 48 pg/ml in BS-IV, p = 0.006). In both groups, there was a positive correlation between age and log(PTH). Levels of 25(OH) vitamin D were not different. Total serum calcium was lower (within normal limits) and age-related serum phosphate (Pi)-SDS was increased in BS-II (1.19 ± 0.71 vs. 0.01 ± 1.04 in BS-IV, p < 0.001). The GFR threshold for Pi reabsorption was higher in BS-II (5.63 ± 1.25 vs. 4.36 ± 0.98, p = 0.002). Spot urine calcium/creatinine ratio and nephrocalcinosis rate (100 vs. 16 %) were higher in the BS-II group. PTH, serum Pi levels, and urinary threshold for Pi reabsorption are significantly elevated in type II vs. type IV BS, suggesting a PTH resistance state. This may be a response to more severe long-standing hypercalciuria, leading to a higher rate of nephrocalcinosis in BS-II.

    To describe the results of a long-term follow-up of Bartter syndrome patients treated with different drugs. Patients were diagnosed according to clinical and laboratory data. Treatment protocol was potassium supplementation, sodium, spironolactone, and non-steroidal anti-inflammatory drug. Patients who developed proteinuria were converted to angiotensin conversion enzyme inhibitor. The variables evaluated for each drug were Z-score for weight and stature, proteinuria, creatinine clearance, gastrointestinal complaints, amount of potassium supplementation, serum potassium and bicarbonate levels, and findings of upper digestive endoscopy. 20 patients were included. Follow-up was 10.1 ± 5.2 years. 17 patients received indomethacin for 5.9 ± 5.3 years; 19 received celecoxib, median of 35 months; and five received enalapril, median of 23 months. During indomethacin, a statistically significant increase was observed in the Z-score for stature and weight, without a change in the creatinine clearance. Seven of 17 patients had gastrointestinal symptoms, and upper digestive endoscopy evidenced gastritis in three patients and gastric ulcer in four patients. During celecoxib use, a significant increase was detected in the Z-score for stature and weight and a reduction of hyperfiltration; seven patients presented gastrointestinal symptoms, and upper digestive endoscopy evidenced mild gastritis in three. During enalapril use, no significant changes were observed in the Z-score for stature, weight and creatinine clearance. The conversion to enalapril resulted in a significant reduction in proteinuria. The authors suggest starting the treatment with celecoxib, and replacing by ACEi if necessary, monitoring the renal function. The safety and efficacy of celecoxib need to be assessed in larger controlled studies. Copyright © 2014 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

    Bartter syndrome encompasses a variety of inheritable renal tubular transport disorders characterized by hypokalemia and hypochloremic metabolic alkalosis. Bartter syndrome Type III is caused by genetic alterations in the chloride channel kidney B (CLCNKB) gene and often presents in the first 2 years of life, known as classic Bartter syndrome. However, in rare cases Bartter syndrome Type III has an antenatal presentation with polyhydramnios, premature delivery and severe dehydration in the first weeks of life. Associations between congenital anomalies of the kidney and urinary tract and Bartter syndrome are extremely rare. This case report presents a girl with Bartter syndrome Type III due to a homozygous CLCNKB mutation and bilateral congenital anomalies of the kidney and urinary tract. In addition, we describe the antenatal presentation as well as its perinatal management.

    Bartter syndrome type 3 is a clinically heterogeneous hereditary salt-losing tubulopathy caused by mutations of the chloride voltage-gated channel Kb gene ( CLCNKB ), which encodes the ClC-Kb chloride channel involved in NaCl reabsorption in the renal tubule. To study phenotype/genotype correlations, we performed genetic analyses by direct sequencing and multiplex ligation-dependent probe amplification and retrospectively analyzed medical charts for 115 patients with CLCNKB mutations. Functional analyses were performed in Xenopus laevis oocytes for eight missense and two nonsense mutations. We detected 60 mutations, including 27 previously unreported mutations. Among patients, 29.5% had a phenotype of ante/neonatal Bartter syndrome (polyhydramnios or diagnosis in the first month of life), 44.5% had classic Bartter syndrome (diagnosis during childhood, hypercalciuria, and/or polyuria), and 26.0% had Gitelman-like syndrome (fortuitous discovery of hypokalemia with hypomagnesemia and/or hypocalciuria in childhood or adulthood). Nine of the ten mutations expressed in vitro decreased or abolished chloride conductance. Severe (large deletions, frameshift, nonsense, and essential splicing) and missense mutations resulting in poor residual conductance were associated with younger age at diagnosis. Electrolyte supplements and indomethacin were used frequently to induce catch-up growth, with few adverse effects. After a median follow-up of 8 (range, 1-41) years in 77 patients, chronic renal failure was detected in 19 patients (25%): one required hemodialysis and four underwent renal transplant. In summary, we report a genotype/phenotype correlation for Bartter syndrome type 3: complete loss-of-function mutations associated with younger age at diagnosis, and CKD was observed in all phenotypes.

    2011-01-01

    Bartter syndrome is a hereditary disorder that has been characterized by the association of hypokalemia, alkalosis, and the hypertrophy of the juxtaglomerular complex with secondary hyperaldosteronism and normal blood pressure. By contrast, the genetic causes of Bartter syndrome primarily affect molecular structures directly involved in the sodium reabsorption at the level of the Henle loop. The ensuing urinary sodium wasting and chronic sodium depletion are responsible for the contraction of the extracellular volume, the activation of the renin-aldosterone axis, the secretion of prostaglandins, and the biological adaptations of downstream tubular segments, meaning the distal convoluted tubule and the collecting duct. These secondary biological adaptations lead to hypokalemia and alkalosis, illustrating a close integration of the solutes regulation in the tubular structures. PMID:21941653

    Full Text Available A rare case of neonatal Bartter syndrome presenting with severe hyperkalemia is reported in a preterm child born to consanguineous parents. This child also had ileal atresia, and meconium plugs were found at laparotomy. The diagnosis of cystic fibrosis was subsequently made on genetic testing. Despite full intensive care management and surgical interventions, he died of respiratory failure after 70 days. This is the first reported case of such conglomeration of pathologies in a newborn child. Second, in highlighting this case we want clinicians to be aware that a subtype of neonatal Bartter syndrome can present with initial hyperkalemia so that an erroneous diagnosis of pseudohypoaldosteronism is not made when this is seen in combination with hyperkalemia and hyperrenin hyperaldosteronism.

It is caused by loss-of-function mutations of the SLC12A1 gene, encoding the furosemide-sensitive Na-K-Cl cotransporter. Recently, a phenotypic variability has been observed in patients with genetically determined BS, including absence of nephrocalcinosis, hypokalemia, and/or metabolic alkalosis in the first year of life as well as persistent metabolic acidosis mimicking distal renal tubular acidosis. We report the case of a child with a genetically determined diagnosis of Bartter syndrome type 1 who presented with a phenotype of nephrogenic diabetes insipidus, with severe hypernatremia and urinary concentrating defect. In these atypical cases, molecular analysis is mandatory to define the diagnosis, in order to establish the correct clinical and therapeutic management.

    Pseudo-Bartter syndrome encompasses a heterogenous group of disorders similar to Bartter syndrome. Sometimes a few status may be nested, as in our case presented here. An 8-month-old boy was referred to our hospital with of intractable diarrhea, polyuria, persistent hypokalemia, abdominal distension and failure to thrive. He was born in the 34 6/7 gestational week (GW) to consanguineous parents. In the 30(th) GW polyhydramnios was verified by ultrasonography. The laboratory results showed hypokalemic-hypochloremic metabolic alkalosis, hyponatremia, and increased urinary loss of chloride, potassium and calcium. An audiogram test revealed complete sensorineural deafness. Ultrasonography revealed medullary nephrocalcinosis in both kidneys. Elevated plasma renin activity and aldosterone were found and a provisional diagnosis of type-IV neonatal Bartter syndrome was made. Treatment with indomethacin, spironolactone and additional intake of NaCl/KCl was initiated. Despite these therapies, the child's diarrhea persisted but serum potassium concentration normalized, and hypercalciuria and urine output reduced. After determining the high fecal chloride concentration, there was an immediate decompensation of the disease on indomethacin withdrawal, thus a diagnosis of type IV neonatal Bartter syndrome complicated with congenital chloride diarrhea was considered. Indomethacin, spironolactone and supplementary therapies with NaCl/KCl were continued, which resulted in the normalization of serum electrolytes as well as his physical development, but high contents of chloride in urine and faeces and nephrocalcinosis remains unchanged during 1-year follow-up. Because of the clinical and laboratory simulations between the various diseases that lead to hypokalemic-hypochloremic metabolic alkalosis, patients must be evaluated carefully.

    Bartter syndrome (BS) is a hereditary disease, with an autosomal recessive or autosomal dominant mode of transmission. It is characterized by salt wasting hypochloraemic, hypokalaemic metabolic alkalosis and hyperreninaemia with normal blood pressure. The primary defect is in the thick ascending limb of loop of Henle (TAL). Herein, we report a case that had typical features of BS like severe dehydration, severe hypokalaemia, metabolic alkalosis and failure to thrive but had normal aldosterone level which is very uncommon.

    Managing neonatal Bartter syndrome by achieving adequate weight gain is challenging. We assessed the correlation between weight gain in neonatal Bartter syndrome and the introduction of fluid and sodium supplementations and indomethacin during the first 4 weeks of life. Daily fluid and electrolytes requirements were analysed using linear regression and Spearman correlation coefficients. The weight gain coefficient was calculated as daily weight gain after physiological neonatal weight loss. We studied seven infants. The highest weight gain coefficients occurred between weeks two and four in the five neonates who either received prompt amounts of fluid (maximum 810 mL/kg/day) and sodium (maximum 70 mmol/kg/day) or were treated with indomethacin. For the two patients with the highest weight gain coefficient, water and sodium supplementations were decreased in weeks two to four leading to a significant negative Spearman correlation between weight gain and fluid supplements (r = -0.55 and -0.68) and weight gain and sodium supplementations (r = -0.96 and -0.72). The two patients with the lowest weight gain coefficient had positive Spearman correlation coefficients between weight gain and fluid and sodium supplementations. Infants with neonatal Bartter syndrome required rapid and enormous fluid and sodium supplementations or the early introduction of indomethacin treatment to achieve adequate weight gain during the early postnatal period. ©2015 Foundation Acta Paediatrica.

    Neonatal Bartter syndrome (NBS) is a rare autosomal recessive renal tubular disorder. This disease is characterized by hypokalemia, hypochloremia, and metabolic alkalosis that is often associated with failure to thrive and recurrent episodes of dehydration. The combination of BS and cholelithiasis in an infant is very rare. Herein, we report a premature male infant with NBS who developed cholelithiasis and hydrocephalus on clinical follow up. We recommend that periodic routine hepatobiliary ultrasonograpic screening for cholelithiasis should be performed in patients with NBS. © 2016 Japan Pediatric Society.

    We report a 5-year-old boy with thiazide-resistant Bartter syndrome. This is highly unusual since thiazide hypersensitivity is a common diagnostic finding in Bartter syndrome patients. Subsequent molecular testing identified compound heterozygosity for two novel mutations in KCNJ1, (c.556A > G and c.683G > A) which is associated with Bartter syndrome, and a paternally inherited polymorphism in SLC12A3 (c.791G > C). Mutations in SLC12A3 cause the thiazide-resistant tubulopathy Gitelman syndrome. Based on published studies of this polymorphism in SLC12A3 and the features of the proband's father, we postulate that this polymorphism modifies the phenotype of Bartter syndrome in the proband to thiazide resistance.

    Gitelman syndrome (GS) and Bartter syndrome (BS) are hereditary salt-losing tubulopathies (SLTs) resulting from defects of renal proteins involved in electrolyte reabsorption, as for sodium-chloride cotransporter (NCC) and furosemide-sensitive sodium-potassium-chloride cotransporter (NKCC2) cotransporters, affected in GS and BS Type 1 patients, respectively. Currently, definitive diagnosis is obtained through expensive and time-consuming genetic testing. Urinary exosomes (UE), nanovesicles released by every epithelial cell facing the urinary space, represent an ideal source of markers for renal dysfunction and injury, because UE molecular composition stands for the cell of origin. On these assumptions, the aim of this work is to evaluate the relevance of UE for the diagnosis of SLTs. UE were purified from second morning urines collected from 32 patients with genetically proven SLTs (GS, BS1, BS2 and BS3 patients), 4 with unclassified SLTs and 22 control subjects (age and sex matched). The levels of NCC and NKCC2 were evaluated in UE by SDS-PAGE/western blotting with specific antibodies. Due to their location on the luminal side of tubular cells, NCC and NKCC2 are well represented in UE proteome. The NCC signal is significantly decreased/absent in UE of Gitelman patients compared with control subjects (Mann-Whitney t-test, P Bartter type 1 (P Bartter type 1 patients from controls and, combined with clinical data, from other Bartter patients. Moreover, the receiver operating characteristic curve analysis using UE NCC densitometric values showed a good discriminating power of the test comparing GS patients versus controls and BS patients (area under the curve value = 0.92; sensitivity 84.2% and specificity 88.6%). UE phenotyping may be useful in the diagnosis of GS and BS, thus providing an alternative/complementary, urine-based diagnostic tool for SLT patient recognition and a diagnostic guidance in complex cases. © The Author 2014.

    Congenital chloride diarrhea (CCD) is a rare autosomal recessive disease which is characterized by intractable diarrhea of infancy, failure to thrive, high fecal chloride, hypochloremia, hypokalemia, hyponatremia and metabolic alkalosis. In this case report, we present the first female and the second official case of CCD in Iran. A 15-month-old girl referred to our hospital due to failure to thrive and poor feeding. She had normal kidneys, liver and spleen. Treating her with Shohl's solution, thiazide and zinc sulfate did not result in weight gain. Consequently, pseudo-Bartter syndrome was suspected, she was treated with intravenous (IV) therapy to which she responded dramatically. In addition, hypokalemia resolved quickly. Since this does not usually happen in patients with the pseudo-Bartter syndrome, stool tests were performed. Abnormal level of chloride in stool suggested CCD and she was thus treated with IV fluid replacement, Total parentral nutrition and high dose of oral omeprazole (3 mg/kg/day). She gained 1 kg of weight and is doing fine until present. CCD is a rare hereditary cause of intractable diarrhea of infancy. It should be considered in infants with unknown severe electrolyte disturbances.

    Bartter syndrome is an autosomal recessive renal tubulopathy that presents with hypokalemic, hypochloremic metabolic alkalosis associated with increased urinary loss of sodium, potassium, calcium and chloride. There is hyperreninemia and hyperaldosteronemia but normotension. A full term male neonate was referred at 20-day of age with features of sepsis and respiratory distress. He was evaluated and managed as case of septicemia with all supportive paraphernalia including mechanical ventilation. Investigations revealed electrolytes imbalance and metabolic alkalosis suggestive of Neonatal Bartter Syndrome (NBS). Raised aldosterone and renin levels confirmed the diagnosis. Electrolyte imbalance was corrected with fluids and indomethacin, treated successfully, discharged and parents counseled. He was thriving well at 9 months of age. Another 2 months old male baby presented with recurrent episodes of lethargy with dehydration and failure to gain weight. Investigations confirmed the diagnosis of NBS. He was also successfully treated with same medication. We report these 2 cases because of the rarity of NBS, presentation of which may mimic common illnesses like sepsis and gastroenteritis.

    Classic Bartter syndrome is a salt-wasting tubulopathy caused by mutations in the CLCNKB (chloride channel Kb) gene. Although growth hormone deficiency has been suggested as a cause for persistent growth failure in patients with classic Bartter syndrome, in our opinion the diagnoses of growth hormone deficiency has been unconvincing in some reports. Moreover, Gitelman syndrome seems to have been confused with Bartter syndrome in some cases in the literature. In the present work, we describe a new case with CLCNKB gene mutations and review the reported cases of classic Bartter syndrome associated with growth hormone deficiency. Our patient was a Japanese boy diagnosed as having classic Bartter syndrome at eight months of age. The diagnosis of Bartter syndrome was confirmed by CLCNKB gene analysis, which revealed compound heterozygous mutations with deletion of exons 1 to 3 (derived from his mother) and ΔL130 (derived from his father). His medical therapy consisted of potassium (K), sodium chloride, spironolactone, and anti-inflammatory agents; this regime was started at eight months of age. Our patient was very short (131.1cm, -4.9 standard deviation) at 14.3 years and showed profoundly impaired growth hormone responses to pharmacological stimulants: 0.15μg/L to insulin-induced hypoglycemia and 0.39μg/L to arginine. His growth response to growth hormone therapy was excellent. The present case strengthens the association between classic Bartter syndrome and growth hormone deficiency. We propose that growth hormone status should be considered while treating children with classic Bartter syndrome.

    Full Text Available Objective: To investigate the phenotype-genotype correlation in different genetic kinds of Bartter syndrome type 3 in children.Methods: Clinical and genetic data of 2 patients with different mutations in Bartter syndrome type 3 was analyzed while the prognosis was compared after a 6-year follow-up or 2-year follow-up, respectively.Results: Bartter syndrome is a kind of autosomal recessive inherited renal disorder. The manifestation and prognosis of Bartter syndrome change with mutation types, and severe mutation were often accompanied with unfavorable prognosis. Comprehensive therapy with ibuprofen, antisterone, captopril, and potassium have remarkable effect, while ibuprofen may improve growth retardation partly.Conclusion: Bartter syndrome should be considered when children have unreasonable continuous electrolyte disturbance, metabolic alkalosis and growth retardation.As a genetic disease, its clinical features depend on the mutation type. It can be ameliorated by electrolyte supplementation, prostaglandin synthetase inhibitors, angiotensin-converting enzyme inhibitors and potassium-sparing diuretic. Considering the following electrolyte disturbances, infections, growth retardation, kidney failure and even death, Bartter syndrome need lifelong treatment, early diagnosis and treatment is the most important.

    Phenotypic overlap exists among type III Bartter syndrome (BS), Gitelman syndrome (GS), and pseudo-BS/GS (p-BS/GS), which are clinically difficult to distinguish. We aimed to clarify the differences between these diseases, allowing accurate diagnosis based on their clinical features. A total of 163 patients with genetically defined type III BS (n = 30), GS (n = 90), and p-BS/GS (n = 43) were included. Age at diagnosis, sex, body mass index, estimated glomerular filtration rate, and serum and urine electrolyte concentrations were determined. Patients with p-BS/GS were significantly older at diagnosis than those with type III BS and GS. Patients with p-BS/GS included a significantly higher percentage of women and had a lower body mass index and estimated glomerular filtration rate than did patients with GS. Although hypomagnesemia and hypocalciuria were predominant biochemical findings in patients with GS, 17 and 23% of patients with type III BS and p-BS/GS, respectively, also showed these abnormalities. Of patients with type III BS, GS, and p-BS/GS, 40, 12, and 63%, respectively, presented with chronic kidney disease. This study clarified the clinical differences between BS, GS, and p-BS/GS for the first time, which will help clinicians establish differential diagnoses for these three conditions.

    The mutations in the CLCNKB gene encoding the ClC-Kb chloride channel are responsible for Bartter syndrome type 3, one of the four variants of Bartter syndrome in the genetically based nomenclature. All forms of Bartter syndrome are characterized by hypokalemia, metabolic alkalosis, and secondary hyperaldosteronism, but Bartter syndrome type 3 has the most heterogeneous presentation, extending from severe to very mild. A relatively large number of CLCNKB mutations have been reported, including gene deletions and nonsense or missense mutations. However, only 20 CLCNKB mutations have been functionally analyzed, due to technical difficulties regarding ClC-Kb functional expression in heterologous systems. This review provides an overview of recent progress in the functional consequences of CLCNKB mutations on ClC-Kb chloride channel activity. It has been observed that 1) all ClC-Kb mutants have an impaired expression at the membrane; and 2) a minority of the mutants combines reduced membrane expression with altered pH-dependent channel gating. Although further investigation is needed to fully characterize disease pathogenesis, Bartter syndrome type 3 probably belongs to the large family of conformational diseases, in which the mutations destabilize channel structure, inducing ClC-Kb retention in the endoplasmic reticulum and accelerated channel degradation.

    Little information is available on a long-term follow-up in Bartter syndrome type I and II. Clinical presentation, treatment and long-term follow-up (5.0-21, median 11 years) were evaluated in 15 Italian patients with homozygous (n = 7) or compound heterozygous (n = 8) mutations in the SLC12A1 (n = 10) or KCNJ1 (n = 5) genes. Thirteen new mutations were identified. The 15 children were born pre-term with a normal for gestational age body weight. Medical treatment at the last follow-up control included supplementation with potassium in 13, non-steroidal anti-inflammatory agents in 12 and gastroprotective drugs in five patients. At last follow-up, body weight and height were within normal ranges in the patients. Glomerular filtration rate was Bartter syndrome had a lower renin ratio (P Bartter syndrome. Patients with Bartter syndrome type I and II tend to present a satisfactory prognosis after a median follow-up of more than 10 years. Gallstones might represent a new complication of antenatal Bartter syndrome.

    Bartter syndrome is a rare autosomal recessive, salt-losing disorder characterized by hypokalemic hypochloremic metabolic alkalosis. A 10-year-old boy had severe growth retardation (height standard deviation score -8.15). He had a thin, triangular face, prominent ears and forehead, and big eyes. Megacystis, bilateral hydroureteronephrosis, and residual urine were detected in ultrasonography, but there was no vesicoureteral reflux. Lumbosacral magnetic resonance (MR) showed posterior disc bulging at L4-5. Serum sodium and chloride levels were normal, but mild hypokalemia was overlooked initially. During follow-up, hypokalemic hypochloremic metabolic alkalosis developed, with high urinary chloride and potassium excretion (52 and 43 mEq/L, respectively). The patient, with renal salt loss, was thought to have classic Bartter syndrome due to absence of nephrocalcinosis, presence of persistent hypercalciuria and sensorineural deafness, and presence of relatively mild clinical and laboratory findings, except polyuria initially. The child was treated with indomethacin, spironolactone, and oral potassium in addition to growth hormone (GH). During treatment, he had considerable increase in weight and height compared with the period of GH therapy only. We present this case because, although growth retardation is a major feature of Bartter syndrome, associated GH deficiency is rarely reported in the literature. Diagnosis of Bartter syndrome was made later, as our patient was followed for megacystis and megaureter secondary to the neurogenic bladder and GH deficiency initially; and proteinuria associated with focal segmental glomerulosclerosis responded to treatment for Bartter syndrome.

    A 30-year-old man with severe antenatal Bartter syndrome, diagnosed and treated in infancy, developed testicular carcinoma. Despite the known renal complications of cisplatin, this drug was used for his chemotherapy because of its superior antineoplastic effect. Nonsteroidal anti-inflammatory drug administration was continued during cisplatin therapy. Despite an increase in his oral potassium requirement, renal function was maintained following completion of chemotherapy. In spite of its significant associated nephrotoxicity, cisplatin can be used in patients with severe antenatal Bartter syndrome if required for therapy of malignancy.

    Bartter syndrome (BS) has been rarely reported in Chinese population except for a few case reports. This investigation was aimed to analyze the mutations of the causal genes in sixteen Chinese patients with BS, and review their followup and treatment. Identify mutations by the next generation sequencing and the multiplex ligation-dependent probe amplification (MLPA). Clinical characteristics and biochemical findings at the first presentation as well as follow-up were reviewed. 15 different CLCNKB gene mutations were identified in fourteen patients with BS, including 11 novel ones. A novel missense mutation and a novel small deletion were found from SLC12A1 gene. A novel gross deletion was found in CLCNKA gene. A recurrent missense mutation was identified from BSND gene. We found that the whole gene deletion mutation of CLCNKB gene was the most frequent mutation (32%), and the rate of gross deletion was up to 50 percent in this group of Chinese patients. The present study has found 19 mutations, including 14 novel ones, which would enrich the human gene mutation database (HGMD) and provide valuable references to the genetic counseling and diagnosis of the Chinese population.

    Neonatal Bartter syndrome (NBS) is an inherited renal tubular disorder associated with hypokalemic alkalosis. Here we report a case of genetically diagnosed NBS. Polyhydramnios was noted at 26 weeks. A boy was born at 31 weeks and 1 day, weighed 1344 g, and had an Apgar score of 8/8. We initiated indomethacin (IND) at a dose of 0.2 mg/kg/d on day 31, and increased it to approximately 3 mg/kg/d. However, his urinary calcium (Ca) levels remained unchanged. At 4 months of age, nephrocalcinosis was detected by ultrasound. The placenta weighed 700 g (+2.7 standard deviations). Although the proportion of terminal villi was consistent with the gestational age, many of them exhibited poorly dilated capillaries. Hemosiderin pigment was seen throughout the amniochorionic connective tissue and along about 50% of the trophoblast basement membrane (TBM). Von Kossa stain revealed the corresponding area of mineralization along the TBM. In our opinion, urinary Ca levels were high and did not change after IND initiation, indicating that nephrocalcinosis may be inevitable. Enhanced inflow of maternal plasma through the basement membrane would cause Ca deposition, given that the same finding was obtained in the case with polyhydramnios. The same mechanism would also explain the hemosiderin pigment distribution. PMID:23943704

    Bartter syndrome (BS) is a clinically and genetically heterogeneous inherited renal tube disorder characterized by renal salt wasting, hypokalemic metabolic alkalosis and normotensive hyperreninemic hyperaldosteronism. There have been several case reports of BS complicated by focal segmental glomerulosclerosis (FSGS). Here, we have reported the case of a BS patient who developed FSGS and subsequent end-stage renal disease (ESRD) and provided a brief literature review. The patient presented with classic BS at 3 months of age and developed proteinuria at 7 years. Renal biopsy performed at 11 years of age revealed a FSGS perihilar variant. Hemodialysis was initiated at 11 years of age, and kidney transplantation was performed at 16 years of age. The post-transplantation course has been uneventful for more than 3 years with complete disappearance of BS without the recurrence of FSGS. Genetic study revealed a homozygous p.Trp(TGG)610Stop(TGA) mutation in the CLCNKB gene. In summary, BS may be complicated by secondary FSGS due to the adaptive response to chronic salt-losing nephropathy, and FSGS may progress to ESRD in some patients. Renal transplantation in patients with BS and ESRD results in complete remission of BS. PMID:21359059

    Bartter syndrome type IV, characterized by salt-losing nephropathies and sensorineural deafness, is caused by mutations of BSND or simultaneous mutations of both CLCNKA and CLCNKB. GJB2 is the primary causative gene for non-syndromic sensorineural deafness and associated with several syndromic sensorineural deafness. Owing to the rarity of Bartter syndrome, only a few mutations have been reported in the abovementioned causative genes. To investigate the underlying mutations in a Chinese patient with Bartter syndrome type IV, genetic analysis of BSND, CLCNKA, CLCNKB and GJB2 were performed by polymerase chain reaction and direct sequencing. Finally, double homozygous mutations c.22C > T (p.Arg8Trp) and c.127G > A (Val43Ile) were detected in exon 1 of BSND. Intriguingly, compound heterozygous mutations c.235delC (p.Leu79CysfsX3) and c.109G > A (p.Val37Ile) were also revealed in exon 2 of GJB2 in the same patient. No pathogenic mutations were found in CLCNKA and CLCNKB. Our results indicated that the homozygous mutation c.22C > T was the key genetic reason for the proband, and a digenic effect of BSND and GJB2 might contributed to sensorineural deafness. To our knowledge, it was the first report showing that the GJB2 gene mutations were detected in Bartter syndrome. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    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. PMID:10779555

    Mutations in the CLCNKB gene encoding the ClC-Kb Cl(-) channel cause Bartter syndrome, which is a salt-losing renal tubulopathy. Here, we investigate the functional consequences of seven mutations. When expressed in Xenopus laevis oocytes, four mutants carried no current (c.736G>C, p.Gly246Arg; c.1271G>A, p.Gly424Glu; c.1313G>A, p.Arg438His; c.1316T>C, p.Leu439Pro), whereas others displayed a 30%-60% reduction in conductance as compared with wild-type ClC-Kb (c.242T>C, p.Leu81Pro; c.274C>T, p.Arg92Trp; c.1052G>C, p.Arg351Pro). Anion selectivity and sensitivity to external Ca(2+) and H(+), typical of the ClC-Kb channel, were not modified in the partially active mutants. In oocytes, we found that all the mutations reduced surface expression with a profile similar to that observed for currents. In HEK293 cells, the currents in the mutants had similar profiles to those obtained in oocytes, except for p.Leu81Pro, which produced no current. Furthermore, p.Arg92Trp and p.Arg351Pro mutations did not modify the unit-conductance of closely related ClC-K1. Western blot analysis in HEK293 cells showed that ClC-Kb protein abundance was lower for the nonconducting mutants but similar to wild-type for other mutants. Overall, two classes of mutants can be distinguished: nonconducting mutants associated with low total protein expression, and partially conducting mutants with unaltered channel properties and ClC-Kb protein abundance. © 2013 WILEY PERIODICALS, INC.

    Bartter syndrome (BS) type 1 is an autosomal recessive kidney disorder caused by loss‑of‑function mutations in the solute carrier family 12 member 1 (SLC12A1) gene. To date, 72 BS type 1 patients harboring SLC12A1 mutations have been documented. Of these 144 alleles studied, 68 different disease‑causing mutations have been detected in 129 alleles, and no mutation was detected in the remaining 15 alleles. The mutation types included missense/nonsense mutations, splicing mutations and small insertions and deletions ranging from 1 to 4 nucleotides. A large deletion encompassing a whole exon in the SLC12A1 gene has not yet been reported. The current study initially identified an undocumented homozygous frameshift mutation (c.1833delT) by Sanger sequencing analysis of a single infant with BS type 1. However, in a subsequent analysis, the mutation was detected only in the father's DNA. Upon further investigation using a next‑generation sequencing approach, a deletion in exons 14 and 15 in both the patient and patient's mother was detected. The deletion was subsequently confirmed by use of a long‑range polymerase chain reaction and was determined to be 3.16 kb in size based on sequencing of the junction fragment. The results of the present study demonstrated that pathogenic variants of SLC12A1 are heterogeneous. Large deletions appear to serve an etiological role in BS type 1, and may be more prevalent than previously thought.

We are presenting an infant with pseudo-Bartter syndrome caused by congenital chloride diarrhoea. Case Outline. A male newborn born in the 37th gestational week (GW to young healthy and non-consanguineous parents. In the 35th GW a polyhydramnios with bowel dilatation was verified by ultrasonography. After birth he manifested several episodes of hyponatremic dehydration with hypochloraemia, hypokalaemia and metabolic alkalosis, so as Bartter syndrome was suspected treatment with indomethacin, spironolactone and additional intake of NaCl was initiated. However, this therapy gave no results, so that at age six months he was rehospitalized under the features of persistent watery diarrhoea, vomiting, dehydration and acute renal failure (serum creatinine 123 μmol/L. The laboratory results showed hyponatraemia (123 mmol/L, hypokalaemia (3.1 mmol/L, severe hypochloraemia (43 mmol/L, alcalosis (blood pH 7.64, bicarbonate 50.6 mmol/L, high plasma renin (20.6 ng/ml and aldosterone (232.9 ng/ml, but a low urinary chloride concentration (2.1 mmol/L. Based on these findings, as well as the stool chloride concentration of 110 mmol/L, the patient was diagnosed congenital chloride diarrhoea. In further course, the patient was treated by intensive fluid, sodium and potassium supplementation which resulted in the normalization of serum electrolytes, renal function, as well as his mental and physical development during 10 months of follow-up. Conclusion. Persistent watery diarrhoea with a high concentration of chloride in stool is the key finding in the differentiation of congenital chloride diarrhoea from Bartter syndrome. The treatment of congenital chloride diarrhoea consists primarily of adequate water and electrolytes replacement.

    Antenatal type I Bartter syndrome (ABS) is usually identified by the presence of polyhydramnios, premature delivery, hypokalemia, metabolic alkalosis, hypercalciuria, and nephrocalcinosis caused by mutations in the Na-K-2Cl cotransporter (NKCC2)-encoding SLC12A1 gene. In this report, we describe a novel presentation of this syndrome with hypercalcemic hypercalciuric hyperparathyroidism, and review the literature of the variable atypical presentations of ABS.

    antenatal variant of Bartter syndrome is characterized by a history of polyhydramnios, premature birth, metabolic alkalosis, hypokalemia, polyuria and renal salt wasting. In this report we present a premature female baby with antenatal Barter syndrome who had three episodes of urinary tract infection (UTI), without evidence for congenital anomaly of the kidneys or urinary tract. antenatal Bartter syndrome was diagnosed according to the standard criteria. Ultrasound scan and voiding cystourethrography were performed to exclude congenital anomaly of the kidneys and urinary tract. the baby presented with early hyperkalemia and acidosis. The typical biochemical features of the Bartter syndrome were observed in the second month. Despite appropriate treatment she had persistent hypercalciuria. The clinical course was complicated with recurrent episodes of febrile UTIs. Urinary tract system imaging did not demonstrate congenital anomalies. She finally died of severe dehydration, acidosis and renal failure. since no congenital anomaly of the kidneys or urinary tract was demonstrated in our patient, we believe that severe, persistent hypercalciuria is the most important risk factor for development of recurrent UTIs.

    Bartter syndrome is a group of rare autosomal-recessive disorders caused by a defect in distal tubule transport of sodium and chloride. Blood gases and plasma electrolytes raise suspicion of this diagnosis and the definitive diagnosis is made by genetic study. Early treatment improves prognosis. The authors present the case of an 11-month-old child with early failure to thrive and severe regurgitation. Blood gases revealed hypochloraemic metabolic alkalosis, hyponatraemia and hypokalaemia. Blood pressure was normal and polyuria was documented. She began therapy with potassium chloride supplementation and indomethacin. There was clinical improvement and plasma potassium and bicarbonate normalised. The molecular study confirmed it was the classic form of Bartter syndrome. Despite being rare in clinical practice, which may lead to unnecessary medical investigation and diagnosis delay, in a child with failure to thrive, hypochloraemic metabolic alkalosis and hypokalaemia, this diagnosis must be considered.

    Maternal electrolyte imbalance is rarely reported as causative factor of severe perinatal brain injury. This case outlines a unique maternal and neonatal pseudo-Bartter syndrome presented with metabolic alkalosis and hypochloremia due to maternal severe vomiting. Neonatal MRI brain revealed extensive brain hemorrhages with porencephalic cysts. Subsequent investigation workup points towards maternal severe metabolic alkalosis as its cause. Careful medical attention should be paid to pregnant women with excessive vomiting to ensure a healthy outcome for both the mother and the baby.

The metabolic changes observed resembled Bartter syndrome, a group of congenital disorders affecting the distal segments of the renal tubules. The metabolic abnormalities reversed spontaneously 6 days after drug discontinuation. Acquired forms of Bartter syndrome have been reported during courses of antibiotic therapy; however, to our knowledge, this is the first documented case associated with colistimethate therapy in an adult.

  14. The Kallikrein-Kinin System in Bartter's Syndrome and Its Response to Prostaglandin Synthetase Inhibition

    The kallikrein-kinin system was characterized in seven patients with Bartter's syndrome on constant metabolic regimens before, during, and after treatment with prostaglandin synthetase inhibitors. Patients with Bartter's syndrome had high values for plasma bradykinin, plasma renin activity (PRA), urinary kallikrein, urinary immunoreactive prostaglandin E excretion, and urinary aldosterone; urinary kinins were subnormal and plasma prekallikrein was normal. Treatment with indomethacin or ibuprofen which decreased urinary immunoreactive prostaglandin E excretion by 67%, decreased mean PRA (patients recumbent) from 17.3±5.3 (S.E.M.) ng/ml per h to 3.3±1.1 ng/ml per h, mean plasma bradykinin (patients recumbent) from 15.4±4.4 ng/ml to 3.9±0.9 ng/ml, mean urinary kallikrein excretion from 24.8±3.2 tosyl-arginine-methyl ester units (TU)/day to 12.4±2.0 TU/day, but increased mean urinary kinin excretion from 3.8±1.3 μg/day to 8.5±2.5 μg/day. Plasma prekallikrein remained unchanged at 1.4 TU/ml. Thus, with prostaglandin synthetase inhibition, values for urinary kallikrein and kinin and plasma bradykinin returned to normal pari passu with changes in PRA, in aldosterone, and in prostaglandin E. The results suggest that, in Bartter's syndrome, prostaglandins mediate the low urinary kinins and the high plasma bradykinin, and that urinary kallikrein, which is aldosterone dependent, does not control kinin excretion. The high plasma bradykinin may be a cause of the pressor hyporesponsiveness to angiotensin II which characterizes the syndrome. PMID:96139

    Reactive oxygen species (ROS) are intermediates in reduction-oxidation reactions that begin with the addition of one electron to molecular oxygen, generating the primary ROS superoxide, which in turn interacts with other molecules to produce secondary ROS, such as hydrogen peroxide, hydroxyl radical, and peroxynitrite. ROS are continuously produced during metabolic processes and are deemed to play an important role in cardiovascular diseases, namely, myocardial hypertrophy and fibrosis and atherosclerosis, via oxidative damage of lipids, proteins, and deoxyribonucleic acid. Angiotensin II (Ang II) is a potent vasoactive agent that also exerts mitogenic, proinflammatory, and profibrotic effects through several signaling pathways, in part involving ROS, particularly superoxide and hydrogen peroxide. Moreover, Ang II stimulates NADPH oxidases, leading to higher ROS generation and oxidative stress. Bartter/Gitelman syndrome patients, despite elevated plasma renin activity, Ang II, and aldosterone levels, exhibit reduced peripheral resistance, normal/low blood pressure, and blunted pressor effect of vasoconstrictors. In addition, notwithstanding the activation of the renin-angiotensin system and the increased plasma levels of Ang II, these patients display decreased production of ROS, reduced oxidative stress, and increased antioxidant defenses. In fact, Bartter/Gitelman syndrome patients are characterized by reduced levels of p22(phox) gene expression and undetectable plasma peroxynitrite levels, while showing increased plasma antioxidant power and expression of antioxidant enzymes, such as heme oxygenase-1. In conclusion, multifarious data suggest that Bartter and Gitelman syndrome patients are a model of low oxidative stress and high antioxidant defenses. The contribution offered by the study of these syndromes in elucidating the molecular mechanisms underlying this favorable status could offer chances for new therapeutic targets in disease characterized by high

    Dent disease is an X-linked recessive disorder affecting the proximal tubule and is characterized by low-molecular-weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis/nephrolithiasis with a variable number of features of Fanconi syndrome. It is most often associated with mutations in CLCN5, which encodes the endosomal electrogenic chloride/proton exchanger ClC-5. Renal acidification abnormalities are only rarely seen in Dent disease, whereas the hypokalemic metabolic alkalosis associated with hyperreninemic hyperaldosteronism (Bartter-like syndrome) has been reported in only one patient so far. We report on a 5-year-old boy with Dent disease caused by mutation in CLCN5 gene, c.1073G>A, who presented with hypokalemic metabolic alkalosis and hyperreninemic hyperaldosteronism persisting over the entire follow-up. No mutations were found in NKCC2, ROMK, NCCT, or ClC-Kb genes. In addition, the patient exhibited growth failure associated with partial growth hormone (GH) deficiency. Coexistence of Bartter-like syndrome features with LMWP should prompt a clinician to search for Dent disease. The Bartter syndrome phenotype seen in Dent disease patients may represent a distinct form of Bartter syndrome, the exact mechanism of which has yet to be fully elucidated. Growth delay that persists in spite of appropriate therapy should raise suspicion of other causes, such as GH deficiency.

    Nephropathic cystinosis is an autosomal recessively inherited metabolic disorder presenting with metabolic acidosis, Fanconi syndrome and renal failure. We present a 6-year-old girl with severe growth failure, hyponatremia and hypokalemia. Her parents were 4(th) degree relatives. Two relatives were diagnosed as end stage renal failure. She also had persistant hypokalemic hypochloremic metabolic alkalosis. Her renal function was normal at presentation. She was thought to have Bartter syndrome with supporting findings of elevated levels of renin and aldosterone with normal blood pressure, and hyperplasia of juxtaglomerular apparatus. Her metabolic alkalosis did not resolve despite supportive treatment. At 6(th) month of follow-up proteinuria, glucosuria and deterioration of renal function developed. Diagnosis of cystinosis was made with slit lamp examination and leukocyte cystine levels. At 12(th) month of follow-up her metabolic alkalosis has converted to metabolic acidosis. In children presenting with persistant metabolic alkalosis, with family history of renal failure, and parental consanguinity, cystinosis should always be kept in mind as this disease is an important cause of end stage renal failure which may have features mimmicking Bartter syndrome.

    Pseudo-Bartter/Gitelman syndrome (p-BS/GS) encompasses a clinically heterogeneous group of inherited or acquired disorders similar to Bartter syndrome (BS) or Gitelman syndrome (GS), both renal salt-losing tubulopathies. Phenotypic overlap frequently occurs between p-BS/GS and BS/GS, which are difficult to diagnose based on their clinical presentation and require genetic tests for accurate diagnosis. In addition, p-BS/GS can occur as a result of other inherited diseases such as cystic fibrosis, autosomal dominant hypocalcemia, Dent disease, or congenital chloride diarrhea (CCD). However, the detection of the variants in genes other than known BS/GS-causing genes by conventional Sanger sequencing requires substantial time and resources. We studied 27 cases clinically diagnosed with BS/GS, but with negative genetic tests for known BS/GS genes. We conducted targeted sequencing for 22 genes including genes responsible for tubulopathies and other inherited diseases manifesting with p-BS/GS symptoms. We detected the SLC26A3 gene variants responsible for CCD in two patients. In Patient 1, we found the SLC26A3 compound heterozygous variants: c.354delC and c.1008insT. In Patient 2, we identified the compound heterozygous variants: c.877G > A, p.(Glu293Lys), and c.1008insT. Our results suggest that a comprehensive genetic screening system using targeted sequencing is useful for the diagnosis of patients with p-BS/GS with alternative genetic origins.

    Dent disease is an X-linked tubulopathy mainly caused by inactivating mutations of CLCN5. Features of Bartter syndrome such as hypokalemic metabolic alkalosis are rarely observed in patients with Dent disease. We report a Japanese male patient with Dent disease who also manifested features of Bartter syndrome. At the age of 3 years, he was diagnosed with Dent disease based on low molecular weight proteinuria and hypercalciuria. One year later, he was found to have features of Bartter syndrome, i.e., hypokalemia and metabolic alkalosis, and high levels of plasma renin activity and aldosterone with a normal blood pressure. Despite medical interventions, he developed chronic kidney disease stage 3 at the age of 21 years. To investigate the molecular basis of his disease, CLCN5, KCNJ1, SLC12A1, and CLCkb were analyzed and a novel mutation (Y567X) in CLCN5 was identified. Hypokalemic metabolic alkalosis is a rare manifestation in Dent disease. It is speculated that Dent patients with features of Bartter syndrome are susceptible to progression to renal failure. To study this hypothesis, additional observations and long-term follow-up of such patients are necessary.

    The calcium sensing receptor (CaSR) plays an important role in calcium homeostasis. Activating mutations of CaSR cause autosomal dominant hypocalcemia by affecting parathyroid hormone secretion in parathyroid gland and calcium resorption in kidney. They can also cause a type 5 Bartter syndrome by inhibiting the apical potassium channel in the thick ascending limb of the loop of Henle in the kidney. This study presents a patient who had autosomal dominant hypocalcemia with Bartter syndrome due to an activating mutation Y829C in the transmembrane domain of the CaSR. Symptoms of hypocalcemia occurred 12 days after birth and medication was started immediately. Medullary nephrocalcinosis and basal ganglia calcification were found at 7 years old and at 17 years old. Three hypercalcemic episodes occurred, one at 14 years old and two at 17 years old. The Bartter syndrome was not severe while the serum calcium concentration was controlled, but during hypercalcemic periods, the symptoms of Bartter syndrome were aggravated.

    Type II Bartter syndrome is caused by mutations in the renal outer medullary potassium (ROMK) channel, but the molecular mechanisms underlying this disease are poorly defined. To rapidly screen for ROMK function, we developed a yeast expression system and discovered that yeast cells lacking endogenous potassium channels could be rescued by WT ROMK but not by ROMK proteins containing any one of four Bartter mutations. We also found that the mutant proteins were significantly less stable than WT ROMK. However, their degradation was slowed in the presence of a proteasome inhibitor or when yeast cells contained mutations in the CDC48 or SSA1 gene, which is required for endoplasmic reticulum (ER)-associated degradation (ERAD). Consistent with these data, sucrose gradient centrifugation and indirect immunofluorescence microscopy indicated that most ROMK protein was ER-localized. To translate these findings to a more relevant cell type, we measured the stabilities of WT ROMK and the ROMK Bartter mutants in HEK293 cells. As in yeast, the Bartter mutant proteins were less stable than the WT protein, and their degradation was slowed in the presence of a proteasome inhibitor. Finally, we discovered that low-temperature incubation increased the steady-state levels of a Bartter mutant, suggesting that the disease-causing mutation traps the protein in a folding-deficient conformation. These findings indicate that the underlying pathology for at least a subset of patients with type II Bartter syndrome is linked to the ERAD pathway and that future therapeutic strategies should focus on correcting deficiencies in ROMK folding. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available Aminoglycoside-induced renal toxicity is well known and may manifest with nonoliguric renal failure or renal tubular dysfunction. Aminoglycoside-induced renal tubular dysfunction could result in diffuse damage or manifest as a Fanconi-like syndrome, Bartter-like syndrome, or distal renal tubular acidosis. We discuss a patient who developed severe renal tubular dysfunction secondary to short-term therapy with Amikacin, resulting in refractory hypokalemia, hypocalcemia, hypomagnesemia, metabolic alkalosis, and polyuria. This constellation of biochemical abnormalities mimic Type 5 Bartter′s syndrome, where there is activating mutation of the calcium sensing receptor in the thick ascending loop of Henle and the distal tubule. In this case this activation of the calcium sensing receptor was triggered by amikacin. This phenomenon has been described with gentamicin though never with amikacin. Recovery of the tubular dysfunction took 15 days following cessation of the offending drug, Amikacin.

    Human Bartter syndrome IV is an autosomal recessive disorder characterized by congenital deafness and severe renal salt and fluid loss. It is caused by mutations in BSND, which encodes barttin, a β-subunit of ClC-Ka and ClC-Kb chloride channels. Inner-ear-specific disruption of Bsnd in mice now reveals that the positive potential, but not the high potassium concentration, of the scala media depends on the presence of these channels in the epithelium of the stria vascularis. The reduced driving force for K+-entry through mechanosensitive channels into sensory hair cells entails a profound congenital hearing loss and subtle vestibular symptoms. Although retaining all cell types and intact tight junctions, the thickness of the stria is reduced early on. Cochlear outer hair cells degenerate over several months. A collapse of endolymphatic space was seen when mice had additionally renal salt and fluid loss due to partial barttin deletion in the kidney. Bsnd−/− mice thus demonstrate a novel function of Cl− channels in generating the endocochlear potential and reveal the mechanism leading to deafness in human Bartter syndrome IV. PMID:18833191

    This article describes two sisters with type III Bartter syndrome (BS) due to a novel missense variant of the CLCNKB gene. The phenotypic expression of the disease was very different in these two siblings. In one sister, the disease followed a very severe course, especially in the neonatal period and as a toddler. Both the classic symptoms and the biochemical features of the syndrome were striking. In addition, she presented with sensorineural deafness, a complication yet unreported in this subtype of BS In contrast, the least affected sister was symptom free and the biochemical features of the disease although present remained discrete throughout the prolonged follow-up. It is suggested that such a difference in the phenotypic expression of the disease is possibly secondary to the modifier effect of a gene and/or results from environmental factor(s).

    A woman with rectal cancer was scheduled for surgery. However, she also had hypokalemia, hyperreninemia, and hyperaldosteronism in the absence of any known predisposing factors or endocrine tumors. She was given intravenous potassium, and her blood abnormalities stabilized after tumor resection. Genetic analysis revealed mutations in several genes associated with Bartter syndrome (BS) and Gitelman syndrome, including SLC12A1 , CLCNKB , CASR , SLC26A3 , and SLC12A3 . Prostaglandin E2 (PGE2) plays an important role in BS and worsens electrolyte abnormalities. The PGE2 level is reportedly increased in colorectal cancer, and in the present case, immunohistochemical examination revealed an increased PGE2 level in the tumor. We concluded that the tumor-related PGE2 elevation had worsened the patient's BS, which became more manageable after tumor resection.

    Pseudo-Bartter Syndrome (PBS), although quite common in patients with cystic fibrosis (CF), is often missed as simple dehydration or Bartter syndrome. This study was performed in patients with PBS to compare the pattern and course of the disease with those with CF not manifesting with this syndrome. All patients with CF who attended the respiratory clinic at Queen Rania Al-Abdallah Hospital from January 2000 to April 2010 were included in this retrospective case-control study. A specially formulated data sheet was used and those with PBS and those not having the syndrome were identified. A total of 110 patients (51% female) with CF with a median age of seven years were followed-up. Eighteen (16.3%) of them had one or more episodes of PBS. The median follow-up period was 6.2 years. All the episodes occurred during summer and in infancy. Median age of the initial episode of PBS was three months. One-third of them were initially followed at the nephrology clinic. Three patterns of PBS were identified: single episode in three (16.6%) patients, recurrent in 12 (66.6%) patients and chronic in three (16.6%) patients. Early colonization of Pseudomonas spp before 1 st birthday was seen in 44% patients with PBS compared with 12% in other CF patients (P-value = 0.0075). The total number of colonized patients and other CF features at the time of the study did not differ significantly among patients, although the mean Shwachman-Kulczycki score is significantly lower in those with recurrent PBS (69 compared with 85 in other CF patients). Gene mutation was identified in only 30% of the entire cohort. PBS is common in patients with CF, and it should be kept in mind in any patient with hypotonic dehydration and metabolic alkalosis. Recurrent pattern is associated with earlier Pseudomonas colonization.

    The infantile variant of Bartter syndrome (IBS) is usually associated with maternal polyhydramnios, premature birth, postnatal polyuria and hypokalemic hypochloremic metabolic alkalosis and a typical appearance. IBS is thought to be an autosomal recessive trait. Several congenital tubular defects are associated with sensorineural deafness (SND). However, an association between the IBS and SND has not been reported so far. Here we describe 5 children of an extended consanguineous Bedouin family with IBS and SND. In 3 of the cases, the typical electrolyte imbalance and facial appearance were detected neonatally. SND was detected as early as age 1 month, suggesting either coincidental homozygotization of 2 recessive genes or a pleiotropic effect of one autosomal recessive gene. This association suggests that evaluation of SND is warranted in every case of IBS. 35 refs., 2 figs., 2 tabs.

    Full Text Available Bartter syndrome (BS I–IV is a rare autosomal recessive disorder affecting salt reabsorption in the thick ascending limb of the loop of Henle. This report highlights clinicopathological findings and genetic studies of classic BS in a 22-year-old female patient who presented with persistent mild proteinuria for 2 years. A renal biopsy demonstrated a mild to moderate increase in the mesangial cells and matrix of most glomeruli, along with marked juxtaglomerular cell hyperplasia. These findings suggested BS associated with mild IgA nephropathy. Focal tubular atrophy, interstitial fibrosis, and lymphocytic infiltration were also observed. A genetic study of the patient and her parents revealed a mutation of the CLCNKB genes. The patient was diagnosed with BS, type III. This case represents an atypical presentation of classic BS in an adult patient. Pathologic findings of renal biopsy combined with genetic analysis and clinicolaboratory findings are important in making an accurate diagnosis.

    Neonatal Bartter syndrome (NBS) is an autosomal recessive renal tubulopathy characterized by hypokalaemic, hypochloraemic metabolic alkalosis associated with increased urinary loss of sodium, potassium, calcium and chloride. There is hyperreninaemia and hyperaldosteronaemia but normotension. Congenital adrenal hyperplasia (CAH), another autosomal recessive condition, may present in the neonatal period with vomiting, hypovolaemia, failure to gain weight or ambiguous genitalia. We report a case of NBS and CAH combination in a neonate. A male neonate born at term was admitted with history of recurrent vomiting and dehydration episodes. Investigations revealed electrolytes imbalance, metabolic alkalosis, raised aldosterone and renin levels suggestive of NBS. He was treated successfully and discharged. He was re-admitted with the same symptoms. Further evaluation confirmed the presence of CAH as well. We report this case because of the rarity of this combination (NBS plus CAH) and to the best of our knowledge this is the first such case report from Pakistan.

    Antenatal Bartter syndrome is a rare condition that can present with different clinical features. These features include early onset maternal polyhydramnios, failure to thrive, prematurity and nephrocalcinosis.We are presenting this 20-day-old girl who had an antenatal history of polyhydramnios. She developed persistent non-bilious vomiting that was associated with constipation soon after birth. She presented with failure to thrive and features suggestive of intestinal obstruction. On the initial evaluation, she was noted to have hypokalaemic, hyponatraemic metabolic alkalosis. The initial work-up was done to exclude surgical and renal causes of her presentation, and the diagnosis was confirmed by gene analysis to be type III-classic Bartter syndrome. She was closely monitored for her growth and development with the appropriate salt replacement therapy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Bartter syndrome Type IV is a rare subtype of the Bartter syndromes that leads to both severe renal salt wasting and sensorineural deafness. This autosomal recessive disease is caused by mutations in the gene encoding barttin, BSND, an essential subunit of the ClC-K chloride channels expressed in renal and inner ear epithelia. Patients differ in the severity of renal symptoms, which appears to depend on the modification of channel function by the mutant barttin. To date, only a few BSND mutations have been reported, most of which are missense or nonsense mutations. In this study, we report the identification of the first insertion mutation, p.W102Vfs*7, in the BSND gene of a newborn girl with acute clinical symptoms including early-onset chronic renal failure. The results support previous data indicating that mutations that are predicted to abolish barttin expression are associated with a severe phenotype and early onset renal failure.

    Bartter syndrome is an autosomal-recessive inherited disease in which patients present with hypokalaemia and metabolic alkalosis. We present two apparently nonrelated cases with antenatal Bartter syndrome type I, due to a novel variant in the SLC12A1 gene encoding the bumetanide-sensitive sodium-(potassium)-chloride cotransporter 2 in the thick ascending limb of the loop of Henle. Blood samples were received from the two cases and 19 of their relatives, and deoxyribonucleic acid was extracted. The coding regions of the SLC12A1 gene were amplified using polymerase chain reaction, followed by bidirectional direct deoxyribonucleic acid sequencing. Each affected child in the two families was homozygous for a novel inherited variant in the SLC12A1gene, c.1614T>A. The variant predicts a change from a tyrosine codon to a stop codon (p.Tyr538Ter). The two cases presented antenatally and at six months of age, respectively. The two cases were homozygous for the same variant in the SLC12A1 gene, but presented clinically at different ages. This could eventually be explained by the presence of other gene variants or environmental factors modifying the phenotypes. The phenotypes of the patients were similar to other patients with antenatal Bartter syndrome. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Mutations of BSND, which encodes barttin, cause Bartter syndrome type IV. This disease is characterized by salt and fluid loss, hypokalemia, metabolic alkalosis, and sensorineural hearing impairment. Barttin is the β-subunit of the ClC-K chloride channel, which recruits it to the plasma membranes, and the ClC-K/barttin complex contributes to transepithelial chloride transport in the kidney and inner ear. The retention of mutant forms of barttin in the endoplasmic reticulum (ER) is etiologically linked to Bartter syndrome type IV. Here, we report that treatment with 17-allylamino-17-demethoxygeldanamycin (17-AAG), an Hsp90 inhibitor, enhanced the plasma membrane expression of mutant barttins (R8L and G47R) in Madin-Darby canine kidney cells. Administration of 17-AAG to Bsnd(R8L/R8L) knock-in mice elevated the plasma membrane expression of R8L in the kidney and inner ear, thereby mitigating hypokalemia, metabolic alkalosis, and hearing loss. These results suggest that drugs that rescue ER-retained mutant barttin may be useful for treating patients with Bartter syndrome type IV. Copyright © 2013 Elsevier Inc. All rights reserved.

    Non-immune hydrops fetalis (NIHF) is a challenging entity as it represents the end stage of several different disorders. Renal and genitourinary causes of NIHF are rare and include congenital renal malformations, tumors and ureter-urethra disorders. Herein, two NIHF cases with different renal causes were presented. The first case that had antenatal NIHF was diagnosed neonatal Bartter syndrome. The second case of NIHF with antenatal large cyst in the surrenal gland area required surgery and ectopic renal cyst was diagnosed. To our best of knowledge, these are the first reports of NIHF associated with neonatal Bartter syndrome and ectopic renal cyst in neonates. Although it may be coincidental, these cases suggest that both neonatal Bartter syndrome and unilateral ectopic renal cyst may cause NIHF development in neonates by several different mechanisms. Therefore, these two rare entities should be suspected in cases of NIHF with similar findings.

    The p.Ala204Thr mutation (exon 7) of the CLCNKB gene is a "founder" mutation that causes most of type III Bartter syndrome cases in Spain. We performed genetic analysis of the CLCNKB gene, which encodes for the chloride channel protein ClC-Kb, in a cohort of 26 affected patients from 23 families. The diagnostic algorithm was: first, detection of the p.Ala204Thr mutation; second, detecting large deletions or duplications by Multiplex Ligation-dependent Probe Amplification and Quantitative Multiplex PCR of Short Fluorescent Fragments; and third, sequencing of the coding and flanking regions of the whole CLCNKB gene. In our genetic diagnosis, 20 families presented with the p.Ala204Thr mutation. Of those, 15 patients (15 families) were homozygous (57.7% of overall patients). Another 8 patients (5 families) were compound heterozygous for the founder mutation together with a second one. Thus, 3 patients (2 siblings) presented with the c. -19-?_2053+? del deletion (comprising the entire gene); one patient carried the p.Val170Met mutation (exon 6); and 4 patients (3 siblings) presented with the novel p.Glu442Gly mutation (exon 14). On the other hand, another two patients carried two novel mutations in compound heterozygosis: one presented the p.Ile398_Thr401del mutation (exon 12) associated with the c. -19-?_2053+? del deletion, and the other one carried the c.1756+1G>A splice-site mutation (exon 16) as well as the already described p.Ala210Val change (exon 7). One case turned out to be negative in our genetic screening. In addition, 51 relatives were found to be heterozygous carriers of the described CLCNKB mutations. In conclusion, different mutations cause type III Bartter syndrome in Spain. The high prevalence of the p.Ala204Thr in Spanish families thus justifies an initial screen for this mutation. However, should it not be detected further investigation of the CLCNKB gene is warranted in clinically diagnosed families.

    Bartter syndrome (BS) is a hereditary condition transmitted as an autosomal recessive (Bartter type 1 to 4) or dominant trait (Bartter type 5). The disease associates hypokalemic alkalosis with varying degrees of hypercalciuria. Here we presented a case (BS type Ⅱ) of a 17 years old female presented with polyhydramnios, polyuria, nephrocalcinosis and hypokalemia, which was alleviated after treatment with celecoxib and vitamin D(3). DNA sequencing identified compound heterozygous KCNJ 1 gene mutations, c. 931C >T (p.R311W) and c. 445-446insCCTGAACAC (p.V149Afs, 150X), with the latter a novel mutation. Her father and mother were heterozygous carriers of c. 931C >T (p.R311W) and c. 445-446insCCTGAACAC (p.V149Afs, 150X), respectively. In conclusion, this case of BS type Ⅱ is caused by a novel compound heterozygous KCNJ 1 mutation. Further studies are needed to verify the effect of celecoxib in BS patients.

    Bartter syndrome (BS) is a group of genetic disorders characterized by hypokalemic metabolic alkalosis, hyponatremia and elevated renin and aldosterone plasma concentrations. BS type II is caused by mutations in the KCNJ1 gene and usually presents with transient hyperkalemia. We report here a novel KCNJ1 mutation in a male neonate, prematurely born after a pregnancy complicated by polyhydramnios. The infant presented with typical clinical and laboratory findings of BS type II, such as hyponatremia, hypochloremic metabolic alkalosis, severe weight loss, elevated renin and aldosterone levels and transient hyperkalemia in the early postnatal period, which were later normalized. Molecular analysis revealed a compound heterozygous mutation in the KCNJ1 gene, consisting of a novel K76E and an already described V315G mutation, both affecting functional domains of the channel protein. Typical manifestations of antenatal BS in combination with hyperkalemia should prompt the clinician to search for mutations in the KCNJ1 gene first. © 2013 The Authors.

    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. Specific therapy for BS is lacking and the only pharmacotherapy up today available is purely symptomatic and characterized by limiting side effects. The improvement of our understanding of the phenotype/genotype correlation and of the precise pathogenic mechanisms associated with BS type 3 as well as the pharmacological characterization of ClC-K chloride channels are fundamental to design therapies tailored upon patients' mutation. This mini review focused on recent studies representing relevant forward steps in the field as well as noteworthy examples of how basic and clinical research can cooperate to gain insight into the pathophysiology of this renal channelopathy, paving the way for a personalized therapy.

    To investigate the mutation of related genes and prenatal diagnosis of a family with Bartter syndrome (BS). The high-throughput capture sequencing technique and PCR-Sanger sequencing were used to detect pathogenic genes in the proband of this family and analyze the whole family at the genomic level. After the genetic cause was clarified, the amniotic fluid was collected from the proband's mother who was pregnant for 5 months for prenatal diagnosis. The proband carried compound heterozygous mutations of c.88C>T(p.Arg30*) and c.968+2T>A in the CLCNKB gene; c.88C>T(p.Arg30*) had been reported as a pathogenic mutation, and c.968+2T>A was a new mutation. Pedigree analysis showed that the two mutations were inherited from the mother and father, respectively. Prenatal diagnosis showed that the fetus did not inherit the mutations from parents and had no mutations at the two loci. The follow-up visit confirmed that the infant was in a healthy state, which proved the accuracy of genetic diagnosis and prenatal diagnosis. The compound heterozygous mutations c.88C>T(p.Arg30*) and c.968+2T>A in the CLCNKB gene are the cause of BS in the proband, and prenatal diagnosis can prevent the risk of recurrence of BS in this family.

    Bartter syndrome (BS) is classified into 5 genotypes according to underlying mutant genes and BS III is caused by loss-of-function mutations in the CLCNKB gene encoding for basolateral ClC-Kb. BS III is the most common genotype in Korean patients with BS and W610X is the most common CLCNKB mutation in Korean BS III. In this study, we tested the hypothesis that the CLCNKB W610X mutation can be rescued in vitro using aminoglycoside antibiotics, which are known to induce translational read-through of a nonsense mutation. The CLCNKB cDNA was cloned into a eukaryotic expression vector and the W610X nonsense mutation was generated by site-directed mutagenesis. Cultured polarized MDCK cells were transfected with the vectors, and the read-through was induced using an aminoglycoside derivative, G418. Cellular expression of the target protein was monitored via immunohistochemistry. While cells transfected with the mutant CLCNKB failed to express ClC-Kb, G418 treatment of the cells induced the full-length protein expression, which was localized to the basolateral plasma membranes. It is demonstrated that the W610X mutation in CLCNKB can be a good candidate for trial of translational read-through induction as a therapeutic modality.

    Pseudo Bartter syndrome (PBS) is defined as hypokalaemic hypochloraemic metabolic alkalosis in the absence of renal tubular pathology. Children with cystic fibrosis (CF) are at risk of developing electrolyte abnormalities and even PBS may occur. 5 months old female infant with a history of two events of dehydration with vomit, refusal to eat, chronic cough, polyuria, malnutrition, metabolic alkalosis, hypokalemia, hyponatremia, hypochloremia and acute renal failure. Chronic cough study was performed, discarding pulmonary tuberculosis, gastroesophageal reflux disease and impaired swallowing. PBS was diagnosed due to hypokalaemic hypochloraemic metabolic alkalosis in the absence of renal tubular pathology. CF was corroborated by electrolytes in sweat and through molecular analysis of the delta F508 mutation. This is one of the few reported cases linking PBS and this mutation. In patients with hyponatremic dehydration episodes with hypokalaemic hypochloraemic metabolic alkalosis, PBS should be considered as differential diagnosis. CF could be presented as PBS, mainly in patients younger than 2 years. Copyright © 2016 Hospital Infantil de México Federico Gómez. Publicado por Masson Doyma México S.A. All rights reserved.

    Bartter syndrome (BS) is a disorder with normotensive hypokalemic alkalosis and hyperreninemic hyperaldosteronemia. BS affects infants or early childhood. Patients with BS type 3 harbor mutation in CLCNKB, Cl channel Kb. Gitelman syndrome (GS) is a disorder in childhood, with mutation in SLC12A3. Isolated adrenocorticotropin deficiency (IAD) causes secondary adrenal insufficiency. Neither elderly cases, nor cases with IAD were previously reported in BS. A 72-year-old man was admitted with acute adrenal crisis. He had been treated for IAD for 19 years. He had no trouble during perinatal period, delivery, and growth. After the recovery from adrenal crisis, laboratory tests revealed hypokalemia; 3.0 mEq/L (normal: 3.5-4.5), impaired renal function: eGFR; 37.6 mL/min/1.73 m2, normomagnesemia; 2.1 mg/dL (1.7-2.3), hyperreninemia; 59.4 ng/mL/h (0.2-2.7), hyperaldosteronemia; 23.5 ng/dL (3.0-15.9), and normal urinary ratio of calcium/creatinine. In diuretic tests, he showed a fine response to furosemide, and a mild response to thiazide. In genetic tests, no mutation of SLC12A3 was found and homozygous mutation: c.1830 G > A in CLCNKB was shown. Thus he was diagnosed as BS type 3. Current case presented with unusual features as BS type 3, 1) his late and mild clinical manifestation suggested GS rather than BS, 2) laboratory data and diuretics tests did not show typical features as BS, and 3) IAD and chronic renal failure altered electrolyte metabolism. In conclusion, current case implies that BS type 3 should be considered even in elderly cases with normotensive hypokalemia, and highlights importance of endocrinological and genetic examinations.

    QT dispersion and JT dispersion are simple noninvasive arrhythmogenic markers that can be used to assess the homogeneity of cardiac repolarization. The aim of this study was to assess QT and JT dispersion and their relation with left ventricular systolic and diastolic functions in children with Bartter syndrome (BS). Nine neonatal patients with BS (median age 9.7 years) and 20 controls (median age 8 years) were investigated at rest. Both study and control subjects underwent electrocardiography (ECG) in which the interval between two R waves and QT intervals, corrected QT, QT dispersion, corrected QT dispersion, JT, corrected JT, JT dispersion and corrected JT dispersion were measured with 12-lead ECG. Two-dimensional, Doppler echocardiographic examinations were performed. Patients and controls did not differ for gender and for serum levels of potassium, magnesium, and calcium (p > 0.05). Both study and control subjects had normal echocardiographic examination and baseline myocardial performance indexes. The QT dispersion and JT dispersion were significantly prolonged in patients with BS compared to those of the controls {37.5 ms [interquartile range (IQR) 32.5-40] vs. 25.5 ms (IQR 20-30), respectively, p = 0.014 and 37.5 ms (IQR 27.5-40) vs. 22.5 ms (IQR 20-30), respectively, p = 0.003}. Elevated QT and JT dispersion during asymptomatic and normokalemic periods may be risk factors for the development of cardiac complications and arrhythmias in children with BS. In these patients the need for systematic cardiac screening and management protocol is extremely important for effective prevention.

    Type III Bartter syndrome (BS) is an autosomal recessive renal tubule disorder caused by loss-of-function mutations in the CLCNKB gene, which encodes the chloride channel protein ClC-Kb. In this study, we carried out a complete clinical and genetic characterization in a cohort of 30 patients, one of the largest series described. By comparing with other published populations, and considering that 80% of our patients presented the p.Ala204Thr Spanish founder mutation presumably associated with a common phenotype, we aimed to test the hypothesis that allelic differences could explain the wide phenotypic variability observed in patients with type III BS. Clinical data were retrieved from the referral centers. The exon regions and flanking intronic sequences of the CLCNKB gene were screened for mutations by polymerase chain reaction (PCR) followed by direct Sanger sequencing. Presence of gross deletions or duplications in the region was checked for by MLPA and QMPSF analyses. Polyuria, polydipsia and dehydration were the main common symptoms. Metabolic alkalosis and hypokalemia of renal origin were detected in all patients at diagnosis. Calciuria levels were variable: hypercalciuria was detected in 31% of patients, while 23% had hypocalciuria. Nephrocalcinosis was diagnosed in 20% of the cohort. Two novel CLCNKB mutations were identified: a small homozygous deletion (c.753delG) in one patient and a small deletion (c.1026delC) in another. The latter was present in compound heterozygosis with the already previously described p.Glu442Gly mutation. No phenotypic association was obtained regarding the genotype. A poor correlation was found between a specific type of mutation in the CLCNKB gene and type III BS phenotype. Importantly, two CLCNKB mutations not previously described were found in our cohort.

    Bartter and Gitelman syndromes (BS and GS) are inherited disorders resulting in defects in renal tubular handling of sodium, potassium and chloride. Previously considered as genotypic and phenotypic heterogeneous diseases, recent evidence suggests that they constitute a spectrum of disease caused by different genetic mutations with the molecular defects of chloride reabsorption originating at different sites of the nephron in each condition. Although they share some characteristic metabolic abnormalities such as hypokalemia, metabolic alkalosis, hyperplasia of the juxtaglomerular apparatus with hyperreninemia, hyperaldosteronism, the clinical and laboratory manifestations may not always allow distinction between them. Diuretics tests, measuring the changes in urinary fractional excretion of chloride from baseline after administration of either hydrochlorothiazide or furosemide show very little change (< 2.3%) in the fractional excretion of chloride from baseline in GS when compared with BS, except when BS is associated with KCNJ1 mutations where a good response to both diuretics exists. The diuretic test is not recommended for infants or young children with suspected BS because of a higher risk of volume depletion in such children. Clinical symptoms and biochemical markers of GS and classic form of BS (type III) may overlap and thus genetic analysis may specify the real cause of symptoms. However, although genetic analysis is available, its use remains limited because of limited availability, large gene dimensions, lack of hot-spot mutations, heavy workup time and costs involved. Furthermore, considerable overlap exists between the different genotypes and phenotypes. Although BS and GS usually have distinct presentations and are associated with specific gene mutations, there remains considerable overlap between their phenotypes and genotypes. Thus, they are better described as a spectrum of clinical manifestations caused by different gene mutations. PMID:26140272

    Inherited classic Bartter syndrome (cBS) is an autosomal recessive renal tubular disorder resulting from inactivating mutations in the asolateral chloride channel (C1C-Kb) and usually presents in early infancy or childhood with mild to moderate hypokalemia. Profound hypokalemic paralysis in patients with cBS is extremely rare, especially in middle age. A 45-year-old Chinese female patient was referred for evaluation of chronic severe hypokalemia despite regular K+ supplementation (1 mmol/kg/d). She had had two episodes of muscle paralysis due to severe hypokalemia (K+ 1.9 - 2.1 mmol/l) in the past 3 years. She denied vomiting, diarrhea, or the use of laxatives or diuretics. Her blood pressure was normal. Biochemical studies showed hypokalemia (K+ 2.5 mmol/l) with renal potassium wasting, metabolic alkalosis (HCO3- 32 mmol/l), normomagnesemia (Mg2+ 0.8 mmol/l), hypercalciuria (calcium to creatinine ratio 0.5 mmol/mmol; normal < 0.22 mmol/mol), high plasma renin activity, but normal plasma aldosterone concentration. Abdominal sonography revealed neither renal stones nor nephrocalcinosis. Acquired causes of cBS such as autoimmune disease and drugs were all excluded. Molecular analysis of the CLCNKB gene, encoding ClC-Kb, and SLC12A3, encoding the thiazide-sensitive sodium chloride cotransporter (NCC), revealed compound heterozygous mutations in CLCNKB (L335P and G470E) inherited from her parents; her SLC12A3 was normal. These two mutations were not identified in 100 healthy subjects. Her plasma K+ concentration rose to 3 - 3.5 mmol/l after the addition of spironolactone. Inherited cBS may present with hypokalemic paralysis and should be considered in adult patients with hypokalemia and metabolic alkalosis.

    We report the case of an infant boy with polyuria and a familial history of central diabetes insipidus. Laboratory blood tests disclosed hypokalemia, metabolic alkalosis, hyperreninemia, and hyperaldosteronism. Plasma magnesium concentration was slightly low. Urine analysis showed hypercalciuria, hyposthenuria, and high excretion of potassium. Such findings oriented toward type III Bartter syndrome (BSIII). Direct sequencing of the CLCNKB gene revealed no disease-causing mutations. The water deprivation test was positive. Magnetic resonance imaging showed a lack of posterior pituitary hyperintensity. Finally, direct sequencing of the AVP-NPII gene showed a point mutation (c.1884G>A) in a heterozygous state, confirming an autosomal dominant familial neurohypophyseal diabetes insipidus (adFNDI). This condition did not explain the patient's phenotype; thus, we investigated for Gitelman syndrome (GS). A direct sequencing of the SLC12A3 gene showed c.269A>C and c.1205C>A new mutations. In conclusion, the patient had a genetic combination of GS and adFNDI with a BSIII-like phenotype.

    Patients with renal diseases associated with salt-losing tubulopathies categorized as Gitelman and classic form of Bartter syndrome have undergone genetic screening for possible mutation capture in two different genes: SLC12A3 and CLCNKB. Clinical symptoms of these two diseases may overlap. Bartter syndrome and Gitelman syndrome are autosomal recessive salt-losing tubulopathies with hypokalemia, metabolic alkalosis, hyperreninemia, hyperplasia of the juxtaglomerular apparatus, hyperaldosteronism, and, in some patients, hypomagnesemia. Here we describe four patients from an inbred family with a novel missense variant in the CLCNKB gene. All of patients are asymptomatic; yet they have the typical metabolic abnormality of salt losing tubulopathies. One of those patients had hypomagnesaemia while others not. Clinical and laboratory data of all patients was described. All 4 patients have a homozygous c.490G > T missense variant in exon 5 of the CLCNKB gene. This variant alters a glycine into a cysteine on amino acid position 164 of the resulting protein (p.Gly164Cys). The c.490G > T variant is a novel variant not previously described in other patients nor controls. Polyphen analysis predicts the variation to be possibly damaging. Analysis of SLC12A3 was normal. Here in we are describing a novel homozygous c.490G > T missense variation was identified in exon 5 of the CLCNKB gene was identified in an Emirati patients with a mild manifestation of Bartter - Gitelman syndrome.

    Bartter syndrome (BS) is an inherited renal tubular disorder characterized by low or normal blood pressure, hypokalemic metabolic alkalosis, and hyperreninemic hyperaldosteronism. Type III BS is caused by loss-of-function mutations in CLCNKB encoding basolateral ClC-Kb. The clinical phenotype of patients with CLCNKB mutations has been known to be highly variable, and cases that are difficult to categorize as type III BS or other hereditary tubulopathies, such as Gitelman syndrome, have been rarely reported. We report a case of a 10-year-old Korean boy with atypical clinical findings caused by a novel CLCNKB mutation. The boy showed intermittent muscle cramps with laboratory findings of hypokalemia, severe hypomagnesemia, and nephrocalcinosis. These findings were not fully compatible with those observed in cases of BS or Gitelman syndrome. The CLCNKB mutation analysis revealed a heterozygous c.139G>A transition in exon 13 [p.Gly(GGG)465Glu(GAG)]. This change is not a known mutation; however, the clinical findings and in silico prediction results indicated that it is the underlying cause of his presentation.

    Cystic fibrosis (CF) is a fatal autosomal-recessive disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. CF is characterized by recurrent pulmonary infection with obstructive pulmonary disease. CF is common in the Caucasian population but is rare in the Chinese population. The symptoms of early-stage CF are often untypical and may sometimes manifest as Bartter syndrome (BS)-like hypokalemic alkalosis. Therefore, the ability of doctors to differentiate CF from BS-like hypokalemic alkalosis in Chinese infants is a great challenge in the timely and accurate diagnosis of CF. In China, sporadic CF has not been diagnosed in children younger than three years of age to date. Three infants, who were initially admitted to our hospital over the period of June 2013 to September 2014 with BS-like hypokalemic alkalosis, were diagnosed with CF through exome sequencing and sweat chloride measurement. The compound heterozygous mutations of the CFTR gene were detected in two infants, and a homozygous missense mutation was found in one infant. Among the six identified mutations, two are novel point mutations (c.1526G > C and c.3062C > T) that are possibly pathogenic. The three infants are the youngest Chinese patients to have been diagnosed with sporadic CF at a very early stage. Follow-up examination showed that all of the cases remained symptom-free after early intervention, indicating the potential benefit of very early diagnosis and timely intervention in children with CF. Our results demonstrate the necessity of distinguishing CF from BS in Chinese infants with hypokalemic alkalosis and the significant diagnostic value of powerful exome sequencing for rare genetic diseases. Furthermore, our findings expand the CFTR mutation spectrum associated with CF.

    ClC-Kb, a member of the ClC family of Cl(-) channels/transporters, plays a major role in the absorption of NaCl in the distal nephron. CLCNKB mutations cause Bartter syndrome type 3, a hereditary renal salt-wasting tubulopathy. Here, we investigate the functional consequences of a Val to Met substitution at position 170 (V170M, α helix F), which was detected in eight patients displaying a mild phenotype. Conductance and surface expression were reduced by ~40-50 %. The regulation of channel activity by external H(+) and Ca(2+) is a characteristic property of ClC-Kb. Inhibition by external H(+) was dramatically altered, with pKH shifting from 7.6 to 6.0. Stimulation by external Ca(2+) on the other hand was no longer detectable at pH 7.4, but was still present at acidic pH values. Functionally, these regulatory modifications partly counterbalance the reduced surface expression by rendering V170M hyperactive. Pathogenic Met170 seems to interact with another methionine on α helix H (Met227) since diverse mutations at this site partly removed pH sensitivity alterations of V170M ClC-Kb. Exploring other disease-associated mutations, we found that a Pro to Leu substitution at position 124 (α helix D, Simon et al., Nat Genet 1997, 17:171-178) had functional consequences similar to those of V170M. In conclusion, we report here for the first time that ClC-Kb disease-causing mutations located around the selectivity filter can result in both reduced surface expression and hyperactivity in heterologous expression systems. This interplay must be considered when analyzing the mild phenotype of patients with type 3 Bartter syndrome.

    Bartter syndrome (BS) Type IV, associated with a G47R mutation in the BSND gene, is known to result in a mild renal phenotype. However, we report here on three brothers with varying degrees of renal dysfunction from mild to end-stage renal disease associated with renal barttin and ClC-K expression. The brothers had histories of polyhydramnios, prematurity, polyuria, deafness, and small body size. Laboratory findings showed hypokalemic metabolic alkalosis, normotensive hyperreninemic hyperaldosteronism, and an increased urinary excretion of sodium, potassium and chloride, consistent with BS Type IV. Microscopic examination of renal tissue showed hyperplasia of cells at the juxtaglomerular apparatus with dilated atrophic tubules and tubulointerstitial fibrosis. A weak barttin signal related to CIC-K expression in the cytoplasm of tubule cells, but not the basement membrane, was noted. A sequence analysis of the BSND gene showed that the affected males were homozygous for a missense G47R mutation in exon 1 of BSND. These findings suggest that the G47R mutation results in a dramatic decrease in barttin expression, which appears to be related to the location of CIC-K being changed from the basement membrane to the cytoplasm in the tubule and might have varying effects on renal function associated with factors other than this gene.

    Pseudo-Bartter syndrome (PBS) describes an uncommon complication of cystic fibrosis leading to hypochloraemic, hypokalaemic metabolic alkalosis. PBS as the sole manifestation of cystic fibrosis in children is extremely rare and has never been described in patients carrying 5T variant. We report a clinical, biochemical and genetic study of a four year-old boy presenting a pseudo-Bartter syndrome as the sole manifestation of cystic fibrosis. All 27 exons and the flanking intron regions of the CFTR gene were analysed by PCR and direct sequencing. Direct sequencing was also used to analyse TG m T n and M470V polymorphisms in the patient and his parents. Two sweat tests were abnormal with elevated chloride levels at 78 and 88 mmol/L. DNA sequencing revealed a heterozygous mutation 711+1 G>T and an IVS8-T5 allele. The mutation 711+1 G>T is in trans with the IVS8-T5-TG11 allele and the child carried M470/V470 genotype. To the best of our knowledge, the genotype 711+1 G>T /IVS8-5T found in our patient is described for the first time. The role of TG11-5T-V470 allele in cases of cystic fibrosis with PB syndrome remains to be determined.

    Inactivated variants in CLCNKB gene encoding the basolateral chloride channel ClC-Kb cause classic Bartter syndrome characterized by hypokalemic metabolic alkalosis and hyperreninemic hyperaldosteronism. Here we identified two cBS siblings presenting hypokalemia in a Chinese family due to novel compound heterozygous CLCNKB mutations (c.848_850delTCT/c.1755A>G). Compound heterozygosity was confirmed by amplifying and sequencing the patient's genomic DNA. The synonymous mutation c.1755A>G (Thr585Thr) was located at +2bp from the 5' splice donor site in exon 15, further transcript analysis demonstrated that this single nucleotide mutation causes exclusion of exon 15 in the cDNA from the proband and his mother. Furthermore, we investigated the expression and protein trafficking change of c.848_850delTCT (TCT) and exon 15 deletion(E15)mutation in vitro. The E15 mutation markedly decreased the expression of ClC-Kb and resulted in a low-molecular-weight band (~55kD) trapping in the endoplasmic reticulum, while the TCT mutant only decreased the total and plasma membrane ClC-Kb protein expression but did not affect the subcellular localization. Finally, we studied the physiological functions of mutations by using whole-cell patch clamp and found that E15 or TCT mutation decreased the current of ClC-Kb/barttin channel. These results suggested that the compound defective mutations of CLCNKB gene are the molecular mechanism of the two cBS siblings.

    Directory of Open Access Journals (Sweden)

    Saskia Letz

    Full Text Available Activating calcium sensing receptor (CaSR mutations cause autosomal dominant hypocalcemia (ADH characterized by low serum calcium, inappropriately low PTH and relative hypercalciuria. Four activating CaSR mutations cause additional renal wasting of sodium, chloride and other salts, a condition called Bartter syndrome (BS type 5. Until today there is no specific medical treatment for BS type 5 and ADH. We investigated the effects of different allosteric CaSR antagonists (calcilytics on activating CaSR mutants.All 4 known mutations causing BS type 5 and five ADH mutations were expressed in HEK 293T cells and receptor signalling was studied by measurement of intracellular free calcium in response to extracellular calcium ([Ca2+]o. To investigate the effect of calcilytics, cells were stimulated with 3 mM [Ca2+]o in the presence or absence of NPS-2143, ATF936 or AXT914.All BS type 5 and ADH mutants showed enhanced signalling activity to [Ca2+]o with left shifted dose response curves. In contrast to the amino alcohol NPS-2143, which was only partially effective, the quinazolinone calcilytics ATF936 and AXT914 significantly mitigated excessive cytosolic calcium signalling of all BS type 5 and ADH mutants studied. When these mutants were co-expressed with wild-type CaSR to approximate heterozygosity in patients, ATF936 and AXT914 were also effective on all mutants.The calcilytics ATF936 and AXT914 are capable of attenuating enhanced cytosolic calcium signalling activity of CaSR mutations causing BS type 5 and ADH. Quinazolinone calcilytics might therefore offer a novel treatment option for patients with activating CaSR mutations.

    Romk knock-out mice show a similar phenotype to Bartter syndrome of salt wasting and dehydration due to reduced Na-K-2Cl-cotransporter activity. At least three ROMK isoforms have been identified in the kidney; however, unique functions of any of the isoforms in nephron segments are still poorly understood. We have generated a mouse deficient only in Romk1 by selective deletion of the Romk1-specific first exon using an ES cell Cre-LoxP strategy and examined the renal phenotypes, ion transporter expression, ROMK channel activity, and localization under normal and high K intake. Unlike Romk−/− mice, there was no Bartter phenotype with reduced NKCC2 activity and increased NCC expression in Romk1−/− mice. The small conductance K channel (SK) activity showed no difference of channel properties or gating in the collecting tubule between Romk1+/+ and Romk1−/− mice. High K intake increased SK channel number per patch and increased the ROMK channel intensity in the apical membrane of the collecting tubule in Romk1+/+, but such regulation by high K intake was diminished with significant hyperkalemia in Romk1−/− mice. We conclude that 1) animal knockouts of ROMK1 do not produce Bartter phenotype. 2) There is no functional linking of ROMK1 and NKCC2 in the TAL. 3) ROMK1 is critical in response to high K intake-stimulated K+ secretion in the collecting tubule.

    Full Text Available Abstract Gitelman syndrome (GS, also referred to as familial hypokalemia-hypomagnesemia, is characterized by hypokalemic metabolic alkalosis in combination with significant hypomagnesemia and low urinary calcium excretion. The prevalence is estimated at approximately 1:40,000 and accordingly, the prevalence of heterozygotes is approximately 1% in Caucasian populations, making it one of the most frequent inherited renal tubular disorders. In the majority of cases, symptoms do not appear before the age of six years and the disease is usually diagnosed during adolescence or adulthood. Transient periods of muscle weakness and tetany, sometimes accompanied by abdominal pain, vomiting and fever are often seen in GS patients. Paresthesias, especially in the face, frequently occur. Remarkably, some patients are completely asymptomatic except for the appearance at adult age of chondrocalcinosis that causes swelling, local heat, and tenderness over the affected joints. Blood pressure is lower than that in the general population. Sudden cardiac arrest has been reported occasionally. In general, growth is normal but can be delayed in those GS patients with severe hypokalemia and hypomagnesemia. GS is transmitted as an autosomal recessive trait. Mutations in the solute carrier family12, member 3 gene, SLC12A3, which encodes the thiazide-sensitive NaCl cotransporter (NCC, are found in the majority of GS patients. At present, more than 140 different NCC mutations throughout the whole protein have been identified. In a small minority of GS patients, mutations in the CLCNKB gene, encoding the chloride channel ClC-Kb have been identified. Diagnosis is based on the clinical symptoms and biochemical abnormalities (hypokalemia, metabolic alkalosis, hypomagnesemia and hypocalciuria. Bartter syndrome (especially type III is the most important genetic disorder to consider in the differential diagnosis of GS. Genetic counseling is important. Antenatal diagnosis for GS

    Amelogenesis imperfecta (AI) is a heterogeneous group of inherited dental enamel defects. It has rarely been reported in association with multiorgan syndromes and metabolic disorders. The metabolic disorders that have been reported in association with AI include hypocalciuria, impaired urinary concentrating ability, and Bartter-like syndrome. In literature, only three cases of AI and distal renal tubular acidosis (dRTA) have been described: two cases in adults and a solitary case in the pediatric age group. Here, we report a child with AI presenting with dRTA; to the best of our knowledge, our reported case is the only second such case in pediatric age group. Our case highlights the importance of recognizing the possibility of renal abnormalities in patients with AI as it will affect the long-term prognosis.

    Full Text Available Gitelman syndrome is a rare autosomal recessive hereditary salt-losing tubulopathy, that manifests as hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria. It is caused by mutations in the solute carrier family 12(sodium/chloride transporters, member 3 (SLC12A3 gene encoding the thiazide-sensitive sodium chloride cotransporter channel (NCCT in the distal convoluted tubule of the kidney. It is associated with muscle weakness, cramps, tetany, vomiting, diarrhea, abdominal pain, and growth retardation. The incidence of growth retardation, the exact cause of which is unknown, is lower than that of Bartter syndrome. Herein, we discuss the case of an overweight 12.9-year-old girl of short stature presenting with hypokalemic metabolic alkalosis. The patient, on the basis of detection of a heterozygous mutation in the SLC12A3 gene and poor growth hormone (GH responses in two provocative tests, was diagnosed with Gitelman syndrome combined with complete GH deficiency. GH treatment accompanied by magnesium oxide and potassium replacement was associated with a good clinical response.

  20. Pseudo-Bartter’s syndrome in patients with cystic fibrosis: A case series and review of the literature

    Directory of Open Access Journals (Sweden)

    Vilotijević-Dautović Gordana

    2015-01-01

    Full Text Available Introduction. Pseudo-Bartter syndrome (PBS is characterized by hyponatremic, hypochloremic metabolic alkalosis that mimics Bartter syndrome but with no pathology in the renal tubules. We present five patients with cystic fibrosis (CF and PBS. Cases Outline. Four children aged between three and five-and-one-half months with previously diagnosed CF and one aged 17 months with previously undiagnosed disease, were hospitalized during the summer season, with severe dehydration, oliguria, apathy and adynamia. Additionally, one of them had an ileostomy due to meconium ileus after birth. All children were on a diet without additional salt intake. Laboratory analysis on admission showed hyponatremia (115-133 mmol/L, mean 122.4 mmol/L, high plasma renin activity (229-500 pg/ml, mean 324 pg/ml and metabolic alkalosis (pH 7.5-7.6, mean 7.56 in all the patients, and in four of them high blood level of aldosterone (74-560 pg/ml, mean 295.9 pg/ml, hypokalemia (2.3-2.8 mmol/L, mean 2.6 mmol/L, hypochloremia (59-71 mmol/L, mean 66 mmol/L and low urinary sodium (5-12 mmol/L, mean 9 mmol/L. After intravenous rehydration followed by additional use of sodium and chloride in mean dosis of 1.78 mmol/kg per day, all the patients made a complete recovery. With advice for additional use of salt in the mentioned amount, the patients were discharged from the hospital. Conclusion. PBS is one of CF complications, especially in infants and young children in situations accompanied by increased sweating and/or other causes of additional loss of sodium and chlorine. Sometimes, as was the case with one of our patients, PBS may be the initial presentation form of the disease.

    Directory of Open Access Journals (Sweden)

    Stelmach Ewa

    2017-06-01

    Full Text Available Introduction. Hyponatremia is an important part of psychiatric practice. In order to analyze its causes and symptoms, the literature on hyponatremia in psychiatric patients has been reviewed. The work has been divided into two separate manuscripts. In the first one the authors discuss the syndrome of inappropriate antidiuretic hormone secretion (SIADH and hyponatremia occurring with the use of psychotropic drugs (antidepressants, antipsychotics, normotimics, while the second paper discusses research on psychogenic polydipsia. The causes of hyponatremia in patients treated in psychiatric wards include: water intoxication associated with polydipsia, somatic comorbidities, side effect of internal medicine and psychiatric drugs. The most common mechanism leading in these cases to hyponatremia is the syndrome of inappropriate secretion of vasopressin (SIADH. The SIADH syndrome is a group of symptoms, first described in 1967 by Schwartz and Bartter in The American Journal of Medicine, which results from the hypersecretion of antidiuretic hormone, also called vasopressin, which causes patients to develop normovolemic hyponatremia. The phenomenon of drug-induced hyponatremia in psychiatric practice is generally observed with the use of antidepressants, antipsychotics and anti-epileptic drugs (used in psychiatry as normotimic drugs.

    TAFRO syndrome is a newly recognized variant of idiopathic multicentric Castleman disease (iMCD) that involves a constellation of syndromes: thrombocytopenia (T), anasarca (A), fever (F), reticulin fibrosis (R), and organomegaly (O). Thrombocytopenia and severe anasarca accompanied by relatively low serum immunoglobulin levels are characteristic clinical findings of TAFRO syndrome that are not present in iMCD-not otherwise specified (iMCD-NOS). Lymph node biopsy is recommended to exclude other diseases and to diagnose TAFRO syndrome, which reveals characteristic histopathological findings similar to hyaline vascular-type CD. TAFRO syndrome follows a more aggressive course, compared with iMCD-NOS, and there is no standard treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

    Despite being known more than 60 years, refeeding syndrome (RS) still bears many uncertainties. For example, its definition is not clear and definite, and the attitude to it varies from the complete neglect to over-prevention.The term "refeeding syndrome" refers to electrolyte and metabolic changes occurring in malnourished patients after the readministration of nutrition. These changes concern especially to phosphates and ions. Potassium, magnesium, naturism and fluids balance are involved. The changes lead to cell energetic metabolism and electric potential disturbances, with related clinical symptoms.Fully developed refeeding syndrome is quite rare; nevertheless it can be fatal for the patient. However, even its development can lead to many complications increasing the patient's morbidity and the length of stay in the hospital. Yet the refeeding syndrome is more or less predictable and if kept in mind also preventable.The aim of this article is to get the reader to know more about this metabolic phenomenon and possible attitudes towards it.

    Poland's syndrome consists of the variable clinical features, but always includes unilateral aplasia of the chest wall muscles and ipsilateral anomalies of upper extremity. The incidence of Poland's syndrome, reported by different authors ranges from 1:10,000 to 1:100,000 and is observed more frequently in males than in females with the right side of the body affected more often than the left. The etiology of this syndrome is still discussed. However most of described cases were sporadic, rare familial incidence of Poland's syndrome were also presented. Therefore different etiologic factors of the Poland's syndrome are taken into account: genetic, vascular compromise during early stages of embriogenesis but also teratogenic effect of environmental xenobiotics (e.g. cigarette smoking by pregnant women). The authors present also the case of 20-years old man with inherited bilateral syndactyly with the right side aplasia of major pectoralis muscle and face asymmetry. The familial history was negative in respect to the features, associated with Poland's syndrome.

    Directory of Open Access Journals (Sweden)

    Fryns Jean-Pierre

    2006-06-01

    Full Text Available Abstract Pfeiffer syndrome is a rare autosomal dominantly inherited disorder that associates craniosynostosis, broad and deviated thumbs and big toes, and partial syndactyly on hands and feet. Hydrocephaly may be found occasionally, along with severe ocular proptosis, ankylosed elbows, abnormal viscera, and slow development. Based on the severity of the phenotype, Pfeiffer syndrome is divided into three clinical subtypes. Type 1 "classic" Pfeiffer syndrome involves individuals with mild manifestations including brachycephaly, midface hypoplasia and finger and toe abnormalities; it is associated with normal intelligence and generally good outcome. Type 2 consists of cloverleaf skull, extreme proptosis, finger and toe abnormalities, elbow ankylosis or synostosis, developmental delay and neurological complications. Type 3 is similar to type 2 but without a cloverleaf skull. Clinical overlap between the three types may occur. Pfeiffer syndrome affects about 1 in 100,000 individuals. The disorder can be caused by mutations in the fibroblast growth factor receptor genes FGFR-1 or FGFR-2. Pfeiffer syndrome can be diagnosed prenatally by sonography showing craniosynostosis, hypertelorism with proptosis, and broad thumb, or molecularly if it concerns a recurrence and the causative mutation was found. Molecular genetic testing is important to confirm the diagnosis. Management includes multiple-staged surgery of craniosynostosis. Midfacial surgery is performed to reduce the exophthalmos and the midfacial hypoplasia.

    Purpose: The purpose of this case study is to highlight the symptoms of the Nutcracker Syndrome (NCS), the methods of clinical investigations and the importance of differential diagnosis. Introduction: The NCS refers to left renal vein entrapment caused by abnormal branching patterns of the superior mesenteric artery from the aorta. 1,2 Clinical case presentation: A 27 years old female presented to the emergency department with complaints of abdominal discomfort, bloating, loose bowel motions and irregular micro-haematuria. The radiologist's report indicated the findings from computed tomography examination to be consistent with anterior NCS. Discussion: In most of the NCS cases the clinical symptoms are non-specific. 3 The syndrome is caused by a vascular disorder, but its clinical manifestation can relate to a wide range of abdominal, urological, endovascular or gynaecological pathologies. 4 Conclusion: Nutcracker Syndrome is a relatively rare disease and underdiagnosed may lead to left renal vein thrombosis

  2. Compartment syndromes

    Science.gov (United States)

    Mubarak, S. J.; Pedowitz, R. A.; Hargens, A. R.

    1989-01-01

    The compartment syndrome is defined as a condition in which high pressure within a closed fascial space (muscle compartment) reduces capillary blood perfusion below the level necessary for tissue viability'. This condition occurs in acute and chronic (exertional) forms, and may be secondary to a variety of causes. The end-result of an extended period of elevated intramuscular pressure may be the development of irreversible tissue injury and Volkmann's contracture. The goal of treatment of the compartment syndrome is the reduction of intracompartmental pressure thus facilitating reperfusion of ischaemic tissue and this goal may be achieved by decompressive fasciotomy. Controversy exists regarding the critical pressure-time thresholds for surgical decompression and the optimal diagnostic methods of measuring intracompartmental pressures. This paper will update and review some current knowledge regarding the pathophysiology, aetiology, diagnosis, and treatment of the acute compartment syndrome.

    Full Text Available Usher syndrome is an autosomal recessive disease with prevalence of 3–6/100.000 and is the most common syndrome that affects vision and hearing. Three subtypes are distinguished on the basis of different degree of hearing loss. All patients develop retinitis pigmentosa with night vision difficulties and constriction of visual field, and ultimately a decline in visual acuity and color vision. Future holds promise for gene therapy. We present a patient with typical clinical picture of Usher syndrome, who started noticing night vision problems at age 13. At age 25 he was operated on for posterior cortical cataracts. At age 34 he has only 5–10° of visual field remaining with 1.0 visual acuity in both eyes. Fundus autofluorescence imaging revealed a typical hyperautofluorescent ring on the border between normal and affected retina.

    Full Text Available Metabolic Syndrome is a combination of risk factors including common etiopathogenesis. These risk factors play different roles in occurence of atherosclerotic diseases, type 2 diabetes, and cancers. Although a compromise can not be achieved on differential diagnosis for MS, the existence of any three criterias enable to diagnose MS. These are abdominal obesity, dislipidemia (hypertrigliceridemia, hypercholesterolemia, and reduced high density lipoprotein hypertension, and elevated fasting blood glucose. According to the results of Metabolic Syndrome Research (METSAR, the overall prevalence of MS in Turkey is 34%; in females 40%, and in males it is 28%. As a result of “Western” diet, and increased frequency of obesity, MS is observed in children and in adolescents both in the world and in Turkey. Resulting in chronic diseases, it is thought that the syndrome can be prevented by healthy lifestyle behaviours. [TAF Prev Med Bull 2010; 9(5.000: 535-540

    Summary Introduction: Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. Objective: To describe a case of Eagle's syndrome. Case Report: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT) of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. Final Comments: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical. PMID:25992033

    Full Text Available Olmsted syndrome is a rare disorder characterized by the combination of periorificial, keratotic plaques and bilateral palmoplantar keratoderma. New associated features are being reported. Olmsted syndrome is particularly rare in a female patient, and we report such a case in a six year-old Indian girl, who presented with keratoderma of her soles since birth and on her palms since the age of two years along with perioral and perinasal hyperkeratosis. She had sparse, light brown, thin hair. Although the psychomotor development of the child was normal until 18 months of age, the keratoderma plaques had restricted the child′s mobility after that stage.

    Eagle syndrome occurs due to elongation of the styloid process or calcification of the stylohyoid ligament, which then may produce a pain sensation due the pressure exerted on various structures in the head and neck. When suspected, imaging helps in identifying the abnormally elongated styloid process or the calcified ligament. In recent years, three-dimensional CT (3DCT) has proved to be valuable in these cases. We report the case of a 62-year-old man with this syndrome in whom imaging with 3DCT conclusively established the diagnosis

Oral manifestations of this condition are not much discussed in the literature. But reported literature includes teeth, palate, periodontal and salivary changes. So the aim of this review is to illustrate the general manifestations, and especially the oral manifestations of Turner syndrome and evaluate their possible management.

    The authors report two recent cases of Fenton's syndrome, a very rare carpal fracture-dislocation. After some anatomophysiopathological considerations and a review of the literature, a wider nosographic frame is proposed in which the entity of the dislocation of the head of capitate bone is not essential. According to both the literature and personal findings, the authors remark that this syndrome is always found in the presence of two morphological variants of the distal radioulnar joint. Finally, the authors stress the importance of a corect diagnosis of this lesion to avoid unnecessary attempts of reduction

    A case of Reiter's syndrome occurring in a young mate aged 20 years having extensive skin lesions of keratoderina blenoffhagica is presented along with a review of literature. Although urethritis was absent, other clinical and histopathological features of the cutaneous lesions led us to the diagnosis. The-possible relationship of postural psoriasis to Reiter's syndrome is discussed. Failure of the patient to respond satisfactorily to steroids, antibiotics etc, prompted the use of rnethotrexate in the case. The result was dramatic, as the patient completely recovered within ten days of starting treatment.

    Full Text Available Larsen syndrome is a rare inherited disorder characterized by congenital dislocation of multiple joints along with other anomalies of heart, face, hands and bones. Larsen syndrome was first described in 1950 by Larsen, Schottstaedt and Bost. In the present report, we describe a 10 year old girl who presented with mid facial hypoplasia with depressed nasal bridge, high arched palate, bilateral talipes equinovarus and high arched feet. On examination, she had short stature (HAZ -3.5 SD with hyperextension of knee joint, fixed flexion of elbow joint. Awareness of this condition and associated complications may help in management and follow up of these patients.

    Joubert syndrome is a rare malformation of the posterior fossa, mainly affecting the cerebellar vermis, which generally appears as a dysplastic lesion. Other structures of the cervico medullary junction may be involved, with accompanying brainstem hypoplasia according to neuroimaging studies. The diagnosis is usually reached during, childhood, based on a constellation of changes in the child's neurological development that are supported by the results of imaging studied. Respiratory problems are the most common signs in newborns,leading to the suspicion of the presence of this syndrome. (Author) 11 refs

    Meigs' syndrome is a rare clinical condition commonly considered to be associated with malignant ovarian tumour. A case of unmarried female is presented who came with a slowly increasing abdominal mass. Clinical and ultrasonic investigations revealed a mobile, solid right adenexal tumour in the lower abdomen, along with ascites and pleural effusion of the right lung. The level of CA 125 was also raised. Diagnosis of Meigs' syndrome was confirmed after surgical intervention. The tumour was successfully removed and pleural effusion disappeared 15 days after the intervention. Cytomorphologic study of both the tumour and ascitic fluid was negative for malignancy. (author)

    A syndrome involving acute urinary retention in combination with sacral radiculitis and cerebrospinal fluid pleocytosis was first described by the American neurosurgeon Charles Elsberg in 1931. In many instances the aetiology is herpes simplex virus type 2 (HSV-2) reactivation from sensory neurons. In this case report we present a 34-year-old pregnant woman with previous undiagnosed sensory lumbosacral symptoms. She was hospitalized with HSV-2 meningitis and lumbosacral radiculitis but no genital rash. A week after the onset of symptoms she developed acute urinary retention, thus indicating Elsberg syndrome.

    Kartagener's Syndrome or Immotile Cilia Syndrome, a variant of Primary Ciliary Dyskinesia (PCD), is a rare autosomal recessive genetic disorder caused by defect in the tiny hair like structure, the cilia lining the respiratory tract (upper and lower), sinuses, eustachian tubes, middle ear and fallopian tubes. Here electron microscopy shows abnormal arrangement of ciliary tubules and patients with Kartagener's syndrome has an absence of dynein arms at the base of the cilia. The inability of cilia to move results in inadequate clearance of bacteria from the air passages, resulting in an increased risk of infection and causing bronchiectasis. Another result of ciliary immobility is infertility. A 60 years old lady was diagnosed as a case of Kartagener's syndrome. She had history of chronic cough for 20 years, irregular fever for 20 years and occasional shortness of breath for 5 years. Relevant investigations revealed dextrocardia, situs inversus, bilateral maxillary sinusitis with non pneumatised frontal sinus and bronchiectasis. She was treated with low concentration oxygen inhalation, antibiotic, bronchodilator, chest physiotherapy including postural drainage, vitamins and other supportive treatment.

    1994-03-01

    Paraneoplastic syndromes (PNS) comprise a diverse group of disorders that are associated with cancer but unrelated to the size, location, metastases, or physiologic activities of the mature tissue of origin. They are remote effects of tumors that may appear as signs, symptoms, or syndromes which can mimic other disease conditions encountered in veterinary medicine. Recognition of PNS is valuable for several reasons: the observed abnormalities may represent tumor cell markers and facilitate early diagnosis of the tumor; they may allow assessment of premalignant states; they may aid in the search metastases; they may help quantify and monitor response to therapy; and, they may provide insight into the study of malignant transformation and oncogene expression. This review will concentrate on the pathophysiology, diagnosis, and treatment of some of the common PNS encountered in veterinary medicine.

    PHACES syndrome associates a segmental facial hemangioma with cerebral malformations, aortic branches/cranial arteries anomalies, cardiac defects, eye anomalies or ventral wall defects. The aim of this study is to analyze our experience with this syndrome. Retrospective study of the cases seen at our unit in the last year. We treat 4 cases; 3 girls and 1 child. Besides the segmental hemangioma they presented: 3 vascular cerebral malformations; 2 structural cardiopathies; 2 cerebral malformations, 1 microftalmia. We did not find ventral wall defects. A case received treatment with two cycles of metilprednisolone i.v. and oral prednisone, with favourable course; two cases received initial treatment with oral prednisone continued of oral propanolol in rising pattern up to 2 mg/kg/day, Obtaining both the detention of the tumour growth and regression of the lesion, with very good tolerance. A 7-year-old patient has been treated with colouring pulse laser for her residual lesions. When we see a segmental facial hemangioma we must perform a wide diagnostic study in order to discard a PHACES syndrome. Multidisciplinar approach to the patient by a wide expert's group gets an earlier diagnose and improves the outcome. Propranolol is a promising therapeutic alternative.

    Helfenstein, Milton; Kuromoto, Jorge

    2010-01-01

    Knee pain is a common complaint in clinical practice, and pes anserinus tendino-bursitis syndrome (PATB) has been frequently diagnosed based only on clinical features that may cause equivocal interpretations. Patients complain of characteristic spontaneous medial knee pain with tenderness in the inferomedial aspect of the joint. Studies with different imaging modalities have been undertaken during the last years to identify whether these patients suffer from bursitis, tendinitis, or both. Nevertheless, little is known regarding the structural defect responsible for this disturbance. Due to these problems and some controversies, we suggest the term "anserine syndrome" for this condition. Diabetes Mellitus is a known predisposing factor for this syndrome. Overweight and osteoarthritis seem to represent additional risk factors; however, their role in the pathophysiology of the disease is not yet understood. Treatment includes non-steroidal anti-inflammatory drugs, physiotherapy, and injections of corticosteroid, with highly variable responses, from 10 days to 36 months to achieve recovery. The lack of knowledge about its epidemiological, etiological, and pathophysiological aspects requires future studies for this common and intriguing disorder.

    2016-01-01

    A 74-year-old gentleman was admitted to the regional neurosciences center with encephalopathy, myokymia, and dysautonomia. Chest imaging had previously identified an incidental mass in the anterior mediastinum, consistent with a primary thymic tumor. Antivoltage-gated potassium channel (anti-VGKC) antibodies were positive (titer 1273 pmol/L) and he was hypokalemic. Electromyogram and nerve conduction studies were in keeping with peripheral nerve hyperexcitability syndrome, and an electroencephalogram was consistent with encephalopathy. A diagnosis of Morvan syndrome was made, for which he was initially treated with high-dose steroids, followed by a 5-day course of intravenous immunoglobulin (IVIG) therapy. He also underwent thymectomy, followed by a postexcision flare of his symptoms requiring intensive care management. Further steroids, plasmapheresis, and IVIG achieved stabilization of his clinical condition, enabling transfer for inpatient neurorehabilitation. He was commenced on azathioprine and a prolonged oral steroid taper. A subsequent presumed incipient relapse responded well to further IVIG treatment. This case report documents a thymoma-associated presentation of anti-VGKC-positive Morvan syndrome supplemented by patient and carer narrative and video, both of which provide valuable further insights into this rare disorder. There are a limited number of publications surrounding this rare condition available in the English literature. This, combined with the heterogenous presentation, association with underlying malignancy, response to treatment, and prognosis, provides a diagnostic challenge. However, the association with anti-VGKC antibody-associated complexes and 2 recent case series have provided some scope for both accurate diagnosis and management. PMID:26740856

    2009-03-01

    Full Text Available Abstract Jacobsen syndrome is a MCA/MR contiguous gene syndrome caused by partial deletion of the long arm of chromosome 11. To date, over 200 cases have been reported. The prevalence has been estimated at 1/100,000 births, with a female/male ratio 2:1. The most common clinical features include pre- and postnatal physical growth retardation, psychomotor retardation, and characteristic facial dysmorphism (skull deformities, hypertelorism, ptosis, coloboma, downslanting palpebral fissures, epicanthal folds, broad nasal bridge, short nose, v-shaped mouth, small ears, low set posteriorly rotated ears. Abnormal platelet function, thrombocytopenia or pancytopenia are usually present at birth. Patients commonly have malformations of the heart, kidney, gastrointestinal tract, genitalia, central nervous system and skeleton. Ocular, hearing, immunological and hormonal problems may be also present. The deletion size ranges from ~7 to 20 Mb, with the proximal breakpoint within or telomeric to subband 11q23.3 and the deletion extending usually to the telomere. The deletion is de novo in 85% of reported cases, and in 15% of cases it results from an unbalanced segregation of a familial balanced translocation or from other chromosome rearrangements. In a minority of cases the breakpoint is at the FRA11B fragile site. Diagnosis is based on clinical findings (intellectual deficit, facial dysmorphic features and thrombocytopenia and confirmed by cytogenetics analysis. Differential diagnoses include Turner and Noonan syndromes, and acquired thrombocytopenia due to sepsis. Prenatal diagnosis of 11q deletion is possible by amniocentesis or chorionic villus sampling and cytogenetic analysis. Management is multi-disciplinary and requires evaluation by general pediatrician, pediatric cardiologist, neurologist, ophthalmologist. Auditory tests, blood tests, endocrine and immunological assessment and follow-up should be offered to all patients. Cardiac malformations can be

    This article reports on 14 cases of a trichorhinophalangeal syndrome in five successive generations. Besides the well-known characteristics of the TRPS the following symptoms observed in this family are new: Teething was considerably delayed, intelligence was reduced, and there were skin manifestations resembling eczema. Besides, struma colli and colitis ulcerosa were also observed. Subsequent observations have to clarify whether these symptoms are a facultative part of the TRPS pattern. The constant appearance of carriers of these characteristics during five generation points to dominant heredity.

    Full Text Available Cardiovascular disease is the leading cause of death in patients with chronic kidney disease.  Heart failure may lead to acute kidney injury and vice versa. Chronic kidney disease may affect the clinical outcomes in patients with cardiovascular disorders. Renal impairment with any degree of albuminuria has been increasingly recognized as an independent risk factor for cardiovascular events and heart failure hospitalizations, while chronic heart failure may cause chronic kidney disease. The bidirectional nature of these disorders contributes to the complexity and the composite definitions of cardiorenal syndromes. However, the most important clinical trials in heart failure tend to exclude patients with significant renal dysfunction. The mechanisms whereby renal insufficiency worsens the outcome in heart failure are not known, and several pathways could contribute to the ‘‘vicious heart/kidney circle.’’ Traditionally, renal impairment has been attributed to the renal hypoperfusion due to reduced cardiac output and decreased systemic pressure. The hypovolemia leads to sympathetic activity, increased renin-angiotensin aldosterone pathway, and arginine-vasopressin release. These mechanisms cause fluid and sodium retention, peripheral vasoconstriction, and volume overload. Therapy to improve renal dysfunction, reduce neurohormonal activation and ameliorate renal blood flow could lead to a reduction in mortality and hospitalization in patients with cardiorenal syndrome.

    Full Text Available Abstract Lowe syndrome (the oculocerebrorenal syndrome of Lowe, OCRL is a multisystem disorder characterised by anomalies affecting the eye, the nervous system and the kidney. It is a uncommon, panethnic, X-linked disease, with estimated prevalence in the general population of approximately 1 in 500,000. Bilateral cataract and severe hypotonia are present at birth. In the subsequent weeks or months, a proximal renal tubulopathy (Fanconi-type becomes evident and the ocular picture may be complicated by glaucoma and cheloids. Psychomotor retardation is evident in childhood, while behavioural problems prevail and renal complications arise in adolescence. The mutation of the gene OCRL1 localized at Xq26.1, coding for the enzyme phosphatidylinositol (4,5 bisphosphate 5 phosphatase, PtdIns (4,5P2, in the trans-Golgi network is responsible for the disease. Both enzymatic and molecular testing are available for confirmation of the diagnosis and for prenatal detection of the disease. The treatment includes: cataract extraction, glaucoma control, physical and speech therapy, use of drugs to address behavioural problems, and correction of the tubular acidosis and the bone disease with the use of bicarbonate, phosphate, potassium and water. Life span rarely exceeds 40 years.

    2018-01-01

    Cotard's syndrome is often described as the delusional belief that one is dead or non-existent. However, Jules Cotard's initial description (1880) of the "delusion of negations" was much richer and also involved delusions and claims of immortality and enormity, feelings of damnation, and illusions of bodily dissolution and transformation. Alternatively conceived as an extreme case of depression, hypochondria, or psychosis, the condition is considered rare and remains poorly understood. Cotard himself provided a taxonomy and several explanations for the condition, focusing on its distinction from classical persecutory delusions and suggesting that it could be a kind of reversed grandiosity. He proposed a psychosensory basis in the dissolution of mental imagery, which he then extended to a more general psychomotor impairment of volition. Other early authors highlighted a disorder of the bodily self, and more recent theories postulated an impairment of right hemispheric functions, leading to perceptual and somatosensory feelings of unreality, which coupled with reasoning impairments and an internalized attributional style led in turn to beliefs of non-existence. However, despite its striking presentation and its relevance to our understanding of self-awareness, Cotard's syndrome remains an elusive condition, rarely reported and poorly researched. © 2018 S.

    2006-12-01

    Full Text Available Abstract KBG syndrome is a rare condition characterised by a typical facial dysmorphism, macrodontia of the upper central incisors, skeletal (mainly costovertebral anomalies and developmental delay. To date, KBG syndrome has been reported in 45 patients. Clinical features observed in more than half of patients that may support the diagnosis are short stature, electroencephalogram (EEG anomalies (with or without seizures and abnormal hair implantation. Cutaneous syndactyly, webbed short neck, cryptorchidism, hearing loss, palatal defects, strabismus and congenital heart defects are less common findings. Autosomal dominant transmission has been observed in some families, and it is predominantly the mother, often showing a milder clinical picture, that transmits the disease. The diagnosis is currently based solely on clinical findings as the aetiology is unknown. The final diagnosis is generally achieved after the eruption of upper permanent central incisors at 7–8 years of age when the management of possible congenital anomalies should have been already planned. A full developmental assessment should be done at diagnosis and, if delays are noted, an infant stimulation program should be initiated. Subsequent management and follow-up should include an EEG, complete orthodontic evaluation, skeletal investigation with particular regard to spine curvatures and limb asymmetry, hearing testing and ophthalmologic assessment.

    2017-01-01

    Objective: Elsberg syndrome (ES) is an established but often unrecognized cause of acute lumbosacral radiculitis with myelitis related to recent herpes virus infection. We defined ES, determined its frequency in patients with cauda equina syndrome (CES) with myelitis, and evaluated its clinical, radiologic, and microbiologic features and outcomes. Methods: We searched the Mayo Clinic medical records for ES and subsequently for combinations of index terms to identify patients with suspected CES and myelitis. Results: Our search yielded 30 patients, 2 diagnosed with ES and an additional 28 with clinical or radiologic evidence of CES retrospectively suspected of having ES. We classified patients in 5 groups according to diagnostic certainty. MRI and EMG confirmed that 2 had only myelitis, 5 only radiculitis, and 16 both. Two had preceding sacral herpes infection and 1 oral herpes simplex. Spinal cord lesions were commonly multiple, discontinuous, not expansile, and centrally or ventrally positioned. Lesions generally spared the distal conus. Nerve root enhancement was occasionally prominent and was smooth rather than nodular. Lymphocytic CSF pleocytosis was common. Thirteen patients (43%) had viral isolation studies, which were commonly delayed; the delay may have accounted for the low rate of viral detection. Acyclovir was administered to 6 patients. Most patients recovered with sequelae; 1 patient experienced encephalomyelitis and died. Conclusion: ES is a definable condition likely responsible for 10% of patients with combined CES and myelitis. Radiologic findings are not entirely specific but may help in differentiating ES from some competing diagnostic considerations. We propose criteria to facilitate diagnosis. PMID:28534040

    2007-09-01

    Full Text Available Abstract Sotos syndrome is an overgrowth condition characterized by cardinal features including excessive growth during childhood, macrocephaly, distinctive facial gestalt and various degrees of learning difficulty, and associated with variable minor features. The exact prevalence remains unknown but hundreds of cases have been reported. The diagnosis is usually suspected after birth because of excessive height and occipitofrontal circumference (OFC, advanced bone age, neonatal complications including hypotonia and feeding difficulties, and facial gestalt. Other inconstant clinical abnormalities include scoliosis, cardiac and genitourinary anomalies, seizures and brisk deep tendon reflexes. Variable delays in cognitive and motor development are also observed. The syndrome may also be associated with an increased risk of tumors. Mutations and deletions of the NSD1 gene (located at chromosome 5q35 and coding for a histone methyltransferase implicated in transcriptional regulation are responsible for more than 75% of cases. FISH analysis, MLPA or multiplex quantitative PCR allow the detection of total/partial NSD1 deletions, and direct sequencing allows detection of NSD1 mutations. The large majority of NSD1 abnormalities occur de novo and there are very few familial cases. Although most cases are sporadic, several reports of autosomal dominant inheritance have been described. Germline mosaicism has never been reported and the recurrence risk for normal parents is very low (

    International Nuclear Information System (INIS)

    Castano Llano, Rodrigo; Chams Anturi, Abraham; Arango Vargas, Paula

    2009-01-01

    We described three cases of superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, chronic duodenal ileus, or cast syndrome. This syndrome occurs when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on endoscopic, radiographic and tomographic findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery is reserved for those who do not respond to nutritional therapy.

  10. [Syndrome X vs metabolic syndrome].

    Morales Villegas, Enrique

    2006-01-01

    Himsworth in 1939 postulated that Diabetes Mellitus type 2 (DM2) was not only an insulin deficiency state but also a cellular insulin insensitivity disease. Thirty years later, DeFronzo and Reaven demonstrated that insulin resistance (IR) preceded and predisposed for DM2 and atherosclerotic-cardiovascular-disease (ACVD). Reaven was the first to point out the relationship between IR and with hyperglycemia, dyslipidosis, and hypertension as mediators for ACVD, creating the concept of Syndrome X (SX) in 1988. WHO and, thereafter, other medical societies and medical groups, mainly ATP-III, in 2002, based on the difficulty of diagnosing IR in a simple, reliable, and inexpensive way, proposed and published the Metabolic Syndrome (MS) concept, as a group of five variables, i.e., obesity, hyperglycemia, hypertriglyceridemia, low HDL, and hypertension, as an easy clinical approximation to suspect and treat an increased cardiometabolic risk. Nowadays, there are deep and extensive controversies on this issue; however, these controversies do not really exist since all discordant points of view are rather quantitative and not qualitative in nature. This article is aimed at differentiating and harmonizing the complementary concepts of SX and MS, at analyzing why MS is a good "clinical window" to look for IR and its underlying manifestations, and finally to accept that the MS concept complements, but does not substitute or antagonize, traditional scales used to asses cardiovascular risk, such as the Framingham scale.

  11. Metabolic Syndrome: Polycystic Ovary Syndrome.

    2015-08-01

    Polycystic ovary syndrome (PCOS) is a heterogeneous condition characterized by androgen excess, ovulatory dysfunction, and polycystic ovaries. It is the most common endocrinopathy among women of reproductive age, affecting between 6.5% and 8% of women, and is the most common cause of infertility. Insulin resistance is almost always present in women with PCOS, regardless of weight, and they often develop diabetes and metabolic syndrome. The Rotterdam criteria are widely used for diagnosis. These criteria require that patients have at least two of the following conditions: hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. The diagnosis of PCOS also requires exclusion of other potential etiologies of hyperandrogenism and ovulatory dysfunction. The approach to PCOS management differs according to the presenting symptoms and treatment goals, particularly the patient's desire for pregnancy. Weight loss through dietary modifications and exercise is recommended for patients with PCOS who are overweight. Oral contraceptives are the first-line treatment for regulating menstrual cycles and reducing manifestations of hyperandrogenism, such as acne and hirsutism. Clomiphene is the first-line drug for management of anovulatory infertility. Metformin is recommended for metabolic abnormalities such as prediabetes, and a statin should be prescribed for cardioprotection if the patient meets standard criteria for statin therapy.

    Lubinsky, Mark; Kantaputra, Piranit Nik

    2016-10-01

    While most supernumerary teeth are idiopathic, they can be associated with a number of Mendelian syndromes. However, this can also be a coincidental finding, since supernumerary teeth occur in 6% or more of the normal population. To better define this relationship, we analyzed the evidence for specific associations. We excluded conditions with a single affected patient reported, supernumerary teeth adjacent to clefts or other forms of alveolar disruption (as secondary rather than primary findings), and natal teeth, which can involve premature eruption of a normal tooth. Since, the cause of supernumerary teeth shows considerable heterogeneity, certain findings are less likely to be coincidental, such as five or more supernumerary teeth in a single patient, or locations outside of the premaxilla. We found only eight genetic syndromes with strong evidence for an association: cleidocranial dysplasia; familial adenomatous polyposis; trichorhinophalangeal syndrome, type I; Rubinstein-Taybi syndrome; Nance-Horan syndrome; Opitz BBB/G syndrome; oculofaciocardiodental syndrome; and autosomal dominant Robinow syndrome. There is also suggestive evidence of an association with two uncommon disorders, Kreiborg-Pakistani syndrome (craniosynostosis and dental anomalies), and insulin-resistant diabetes mellitus with acanthosisnigricans. An association of a Mendelian disorder with a low frequency manifestation of supernumerary teeth is difficult to exclude without large numbers, but several commonly cited syndromes lacked evidence for clear association, including Hallermann-Streiff syndrome, Fabry disease, Ehlers-Danlos syndrome, Apert and Crouzon syndromes, Zimmermann-Laband syndrome, and Ellis-van Creveld syndrome. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  14. HEPATORENAL SYNDROME

    2001-12-01

    Full Text Available Background. Hepatorenal syndrome (HRS is acommon complication of advanced hepatic disease characterizedby marked abnormalities in arterial circulation and byrenal failure. An extreme arteriolar vasodilatation located inthe splanchnic circulation results in a reduction of total systemicvascular resistence and arterial hypotension. Vasoconstrictionoccurs in the renal circulation as in all other extrasplanchnicvascular territories. In the kidney, marked renalvasoconstriction results in a low glomerular filtration rate.Conclusions. The diagnosis of HRS is currently based on exclusionof other causes of renal failure. Prognosis of patientswith HRS is very poor. Liver transplantation is the best therapeuticoption, but it is seldom applicable due to the short survivalexpectancy of most patients with HRS, particularly thosewith the rapidly progressive type of HRS. New therapies developedduring the last few years, such as the use of systemicvasoconstrictors or transjugular intrahepatic portosystemicshunts (TIPS appear promising. Such treatments are of interestnot only as a bridge to liver transplantation but also as atherapy for patients who are not candidates for transplantation.

    Full Text Available Abstract Noonan Syndrome (NS is characterised by short stature, typical facial dysmorphology and congenital heart defects. The incidence of NS is estimated to be between 1:1000 and 1:2500 live births. The main facial features of NS are hypertelorism with down-slanting palpebral fissures, ptosis and low-set posteriorly rotated ears with a thickened helix. The cardiovascular defects most commonly associated with this condition are pulmonary stenosis and hypertrophic cardiomyopathy. Other associated features are webbed neck, chest deformity, mild intellectual deficit, cryptorchidism, poor feeding in infancy, bleeding tendency and lymphatic dysplasias. The syndrome is transmitted as an autosomal dominant trait. In approximately 50% of cases, the disease is caused by missense mutations in the PTPN11 gene on chromosome 12, resulting in a gain of function of the non-receptor protein tyrosine phosphatase SHP-2 protein. Recently, mutations in the KRAS gene have been identified in a small proportion of patients with NS. A DNA test for mutation analysis can be carried out on blood, chorionic villi and amniotic fluid samples. NS should be considered in all foetuses with polyhydramnion, pleural effusions, oedema and increased nuchal fluid with a normal karyotype. With special care and counselling, the majority of children with NS will grow up and function normally in the adult world. Management should address feeding problems in early childhood, evaluation of cardiac function and assessment of growth and motor development. Physiotherapy and/or speech therapy should be offered if indicated. A complete eye examination and hearing evaluation should be performed during the first few years of schooling. Preoperative coagulation studies are indicated. Signs and symptoms lessen with age and most adults with NS do not require special medical care.

    Full Text Available Goldenhar syndrome (GHS is also known as Oculo-Auriculo-Vertebral (OAV syndrome or Branchial arch syndrome. Duane retraction syndrome (DRS is a congenital disorder of ocular motility characterized by limited abduction, adduction or both. It is unilateral in 80% of cases. The important and interesting part of this eight months old child is presence of GHS with DRS. She has bilateral invol-vement, which is seen in only 5-8% of GHS, as compared to high incidence of unilateral involve-ment. This child also had refractive error of + 6.00/ - 1.5 * 180. At four year of age her vision with glass was 6/9. Children with GHS and DRS should have early eye examination done to treat the problem of refractive error. Keywords: Duane retraction syndrome; goldenhar syndrome, refractive error.

    Full Text Available Renal failure is a common major complication in patients with advanced cirrhosis and generally indicates a poor prognosis when combined with liver failure. Hepatorenal syndrome (HRS is characterised by a combination of disturbances in circulatory and kidney function. Arterial pressure is decreased in the systemic circulation due to reduced total systemic vascular resistance. Kidney dysfunction is caused by reduction in renal blood flow. The diagnosis of HRS is based on exclusion of other disorders that cause acute kidney injury in cirrhosis as there are no specific tests. There are two types of HRS with different characteristics and prognostics. Liver transplantation is the treatment of choice for all patients without contraindication. The best approach to the pharmacologic management is the administration vasoconstrictor drugs based on the pathogenesis. Many vasoconstrictors including vasopressin analogues (terlipressin, ornipressin and vasopressin, somatostatin analogues (octreotide and alpha-adrenergic analogues (midodrine and norepinephrine have been studied. In most of the studies intravenous albumin therapy was coadministered with vasoconstrictor drugs and suggested that albumin should be considered as the component of pharmacologic intervention in patients with HRS. Renal replacement therapy in the form of hemodialysis or continuous venovenous hemofiltration has been used in the management of HRS patients awaiting transplantation or in those with acute potentially reversible conditions. The artificial hepatic support systems require further investigation. (Journal of the Turkish Society Intensive Care 2012; 10: 37-44

    In a child with short stature, the finding of normal or elevated GH levels in the presence of low concentrations of IGF-I raises the following possibilities. (1) A modification of the GH molecule, which is still detected by RIA, but inactive biologically. Therefore, an RRA or bioassay for hGH should result in considerably lower GH measurements compared with RIA determinations in the same sample. As both bioassays as well as RRAs are not widely available and are hampered by several difficulties, few children with this presumptive diagnosis have been described. So far, it has not been possible to define a specific molecular defect in one of these patients. (2) Abnormalities of the GH receptor or postreceptor mechanisms lead to a GH insensitivity syndrome. Laron-type dwarfism is usually due to a deletion in the gene for hepatic GH receptors: the serum binding protein for GH is absent. In three additional populations, the Pygmies of Zaire, the little women of Loja in Ecuador and the Mountain Ok people in Papua New Guinea, alterations of GH receptor function have been described. Finally, some reports describe patients with normal or elevated serum levels of both growth hormone and IGF-I in whom resistance to IGF has been implied in the pathogenesis of small stature.

    Science.gov (United States)

    Papper, S

    1980-01-01

    Renal failure without apparent cause (the hepatorenal syndrome) may develop in the course of cirrhosis of the liver. While the development of renal failure bears a poor prognosis, spontaneous recovery can occur. The data suggest that for the most part patients die in rather than of renal failure. The latter seems to be only part of a broader more fundamental disturbance. The pathogenesis of HRS is unknown, but the evidence supports an impairment of effective renal perfusion. The two major hypotheses concerning the nature of the impaired perfusion are that it is a physiologic response to alterations in the extrarenal circulation, and that there is an unidentified humoral agent(s) produced by or inadequately inactivated by or bypassing the diseased liver and causing circulatory changes in the kidney as well as in other organs. It is possible that both mechanisms are operative. Treatment is unsatisfactory and emphasis is presently best placed upon searching for more treatable causes of renal functional impairment in individual patients.

    The Capgras syndrome is one of delusional-like misidentification syndrome in which a person holds a delusion that one or several his/her friends or relatives have been replaced by an identical-looking impostor. As any other delusional disorder, the Capgras syndrome is characterized by stability despite the indisputable arguments against fault views. Initially, this syndrome was considered as a presentation of schizophrenia but later it has been described in brain organic disorders, primarily in elderly patients with dementia.

    Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological entity characterized by headache, confusion, visual disturbances, seizures and posterior transient changes on neuroimaging. PRES has been described in several conditions including hypertensive encephalopathy, preeclampsia, eclampsia, infections, electrolyte imbalance, hypercalcaemia and use of several drugs. It occurs due to elevated blood pressure which exceeds the autoregulatory capacity of brain vasculature. The posterior circulation supplied by vertibro-basilar system has poor sympathetic innervation and, therefore, is frequently involved. The role of neuroimaging is to establish the initial diagnosis and to exclude other causes of neurological symptoms and signs. NCCT is sufficient to make the diagnosis in a proper clinical setting. MRI features are characteristic and has diagnostic and prognostic value. Diffusion weighted imaging (DWI) can differentiate this condition from ischemia/cytotoxic edema. Differential diagnosis of PRES includes PCA territory infarcts, venous thrombosis, demyelinating disorders, vasculitis and encephalitis. The diagnosis has important implications because the reversibility of the clinico-radiological abnormalities is contingent on the prompt control of blood pressure and/or withdrawing of the offending drug. We describe here a case of PRES in a 12 years old girl with acute lymphoblasts leukaemia, treated with cytostatics-vincristine, pharmorubycin and methotrexate. After 39 days from the beginning of the treatment there are good results in the myelogram and the flowcytometric examination, but the patient made two tonic-clonic seizures. CT and MRI were made and signs of leucoencephalopathy were diagnosed. Several control MRI examinations after cessation of the therapy and disappearance of the neurologic symptoms were made. The normal findings and the clinical course were the reasons for the PRES diagnosis

    Despite considerable progress in the diagnosis and treatment of deep vein thrombosis (DVT) of the lower extremities, one of every three patients will develop postthrombotic sequelae within 2 years; these sequelae are severe in approximately 20% of cases and produce considerable socioeconomic consequences. Among factors potentially related to the development of the postthrombotic syndrome (PTS) are older age, obesity, insufficient oral anticoagulant therapy, and recurrent ipsilateral thrombosis. Whether the extent and location of the initial thrombosis are associated with the development of PTS is controversial. Based on recent findings, the lack of vein recanalization within the first 6 months appears to be an important predictor of PTS, whereas the development of transpopliteal venous reflux is not. The diagnosis of PTS can be made on clinical grounds for patients with a history of DVT. The combination of a standardized clinical evaluation with the results of compression ultrasonography and Doppler ultrasound helps diagnose or exclude a previous proximal vein thrombosis. According to the results of recent clinical studies, the prompt administration of adequate compression elastic stockings in patients with symptomatic DVT has the potential to reduce the frequency of late PTS development by half. The management of this condition is demanding and often frustrating. However, when carefully supervised and instructed to wear proper elastic stockings, more than 50% of patients will either remain stable or improve during long-term follow-up. Clinical presentation helps predict the prognosis; the outcome of patients who refer with initially severe manifestations is more favorable than that of patients whose symptoms deteriorate progressively over time.

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Full Text Available Abstract First described in 1983, Barth syndrome (BTHS is widely regarded as a rare X-linked genetic disease characterised by cardiomyopathy (CM, skeletal myopathy, growth delay, neutropenia and increased urinary excretion of 3-methylglutaconic acid (3-MGCA. Fewer than 200 living males are known worldwide, but evidence is accumulating that the disorder is substantially under-diagnosed. Clinical features include variable combinations of the following wide spectrum: dilated cardiomyopathy (DCM, hypertrophic cardiomyopathy (HCM, endocardial fibroelastosis (EFE, left ventricular non-compaction (LVNC, ventricular arrhythmia, sudden cardiac death, prolonged QTc interval, delayed motor milestones, proximal myopathy, lethargy and fatigue, neutropenia (absent to severe; persistent, intermittent or perfectly cyclical, compensatory monocytosis, recurrent bacterial infection, hypoglycaemia, lactic acidosis, growth and pubertal delay, feeding problems, failure to thrive, episodic diarrhoea, characteristic facies, and X-linked family history. Historically regarded as a cardiac disease, BTHS is now considered a multi-system disorder which may be first seen by many different specialists or generalists. Phenotypic breadth and variability present a major challenge to the diagnostician: some children with BTHS have never been neutropenic, whereas others lack increased 3-MGCA and a minority has occult or absent CM. Furthermore, BTHS was first described in 2010 as an unrecognised cause of fetal death. Disabling mutations or deletions of the tafazzin (TAZ gene, located at Xq28, cause the disorder by reducing remodeling of cardiolipin, a principal phospholipid of the inner mitochondrial membrane. A definitive biochemical test, based on detecting abnormal ratios of different cardiolipin species, was first described in 2008. Key areas of differential diagnosis include metabolic and viral cardiomyopathies, mitochondrial diseases, and many causes of neutropenia and

    Full Text Available Ahmed H Alhammadi, Mohamed Khalifa, Lolwa Alnaimi Department of Pediatrics, Division of General Pediatrics, Hamad Medical Corporation, Doha, Qatar Abstract: Bartter syndrome is an autosomal recessive disease manifested by a defect in chloride transport in the thick loop of Henle, with different genetic origins and molecular pathophysiology. Children with Bartter syndrome generally present in early infancy with persistent polyuria and associated dehydration, electrolyte imbalance, and failure to thrive. Although early diagnosis and appropriate treatment of Bartter syndrome may improve the outcome, some children will progress to renal failure. We report a case of an 8-week-old infant who was admitted for electrolyte imbalance and failure to thrive. Laboratory studies revealed hypochloremic metabolic alkalosis with severe hypokalemia. Health care providers should consider Bartter syndrome when excessive chloride losses appear to be renal in origin and the patient has normal blood pressure and high levels of serum renin and aldosterone. Treatments, including indomethacin, spironolactone, and aggressive fluid and electrolyte replacement, may prevent renal failure in children with Bartter syndrome. Molecular genetics studies are indicated to identify the primary genetic defect. Keywords: Bartter syndrome, failure to thrive, metabolic alkalosis

    2014-03-01

    The incidence of cardiovascular disease increases considerably after the menopause. One reason for the increased cardiovascular risk seems to be determined by metabolic syndrome, in which all components (visceral obesity, dyslipidemia, hypertension, and glucose metabolism disorder) are associated with higher incidence of coronary artery disease. After menopause, metabolic syndrome is more prevalent than in premenopausal women, and may plays an important role in the occurrence of myocardial infarction and other atherosclerotic and cardiovascular morbidities. Obesity, an essential component of the metabolic syndrome, is also associated with increased incidence of breast, endometrial, bowel, esophagus, and kidney cancer. The treatment of metabolic syndrome is based on the change in lifestyle and, when necessary, the use of medication directed to its components. In the presence of symptoms of the climacteric syndrome, hormonal therapy, when indicated, will also contribute to the improvement of the metabolic syndrome.

    Tourette Syndrome (TS) is a neurodevelopmental disorder characterized by chronic motor and vocal tics. Although it is a common disorder in childhood, the etiology of Tourette Syndrome has not been fully elucidated yet. Studies, -conducted so far- have revealed differences in neurobiological structures of individuals who suffer from Tourette Syndrome. The objective of this review is to assess etiological and pathophysiological studies in the Tourette Syndrome literature. An electronical search was conducted in PubMed database using the keywords tic disorders, Tourette Syndrome, neurobiology, genetics, neuroimaging and animal models. Research and review studies published between 1985 and 2015, with a selection preference towards recent publications, were reviewed. According to the studies, genetic predisposition hypothesis is considered as a priority. However, a precise genetic disorder associated with Tourette Syndrome has not been found. The evidence from postmortem and neuroimaging studies in heterogenous patient groups and animal studies supports the pathological involvement of cortico-striato-thalamo-cortical (CSTC) circuits in Tourette Syndrome. Consequently, the most emphasized hypothesis in the pathophysiology is the dopaminergic dysfunction in these circuits. Furthermore, these findings of the animal, postmortem and neuroimaging studies have confirmed the neurodevelopmental hypothesis of Tourette Syndrome. In conclusion, more studies are needed to understand the etiology of the disorder. The data obtained from neurobiological studies of the disorder will not only shed light on the way of Tourette Syndrome, but also guide studies on its treatment options.

    Cushing's syndrome is a rare condition in the general population and is even less common during pregnancy with only a few cases reported in literature. The diagnosis of Cushing's syndrome may be difficult during pregnancy because the typical features of the disorder and pregnancy may overlap. However, Cushing's syndrome results in increased fetal and maternal complications, and diagnosis and treatment are critical. This report describes a case of 26-year-old female at the 19th week of pregnancy with symptoms and signs of hypercortisolism, where ACTH-independent Cushing's syndrome was diagnosed and treated by robotic laparoscopic adrenalectomy at the 21th week of gestation.

    Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

    Polycystic ovary syndrome (PCOS) is a heterogeneous disorder, where the main clinical features include menstrual irregularities, sub-fertility, hyperandrogenism, and hirsutism. The prevalence of PCOS depends on ethnicity, environmental and genetic factors, as well as the criteria used to define it. On the other hand, metabolic syndrome is a constellation of metabolic disorders which include mainly abdominal obesity, insulin resistance, impaired glucose metabolism, hypertension and dyslipidaemia. These associated disorders directly increase the risk of Type 2 diabetes mellitus (DMT2), coronary heart disease (CHD), cardiovascular diseases (CVD) and endometrial cancer. Many patients with PCOS have features of metabolic syndrome such as visceral obesity, hyperinsulinaemia and insulin resistance. These place patients with PCOS under high risk of developing cardiovascular disease (CVD), Type 2 diabetes (DMT2) and gynecological cancer, in particular, endometrial cancer. Metabolic syndrome is also increased in infertile women with PCOS. The aim of this review is to provide clear and up to date information about PCOS and its relationship with metabolic syndrome, and the possible interaction between different metabolic disorders.

  7. Wolfram syndrome 1 and Wolfram syndrome 2.

    Wolfram syndrome 1 (WS1) is an autosomal recessive disorder characterized by diabetes insipidus, diabetes mellitus, optic atrophy, and deafness (DI DM OA D syndrome) associated with other variable clinical manifestations. The causative gene for WS1 (WFS1) encoding wolframin maps to chromosome 4p16.1. Wolframin has an important function in maintaining the homeostasis of the endoplasmic reticulum (ER) in pancreatic β cells. Recently, another causative gene, CISD2, has been identified in patients with a type of Wolfram syndrome (WS2) resulting in early optic atrophy, diabetes mellitus, deafness, decreased lifespan, but not diabetes insipidus. The CISD2-encoded protein ERIS (endoplasmic reticulum intermembrane small protein) also localizes to ER, but does not interact directly with wolframin. ERIS maps to chromosome 4q22. Numerous studies have shown an interesting similarity between WFS1 and CISD2 genes. Experimental studies demonstrated that the Cisd2 knockout (Cisd2) mouse shows premature aging and typical symptoms of Wolfram syndrome. These researches provide interesting insight into the relation of neurodegenerative diseases, mitochondrial disorders, and autophagy and are useful for the pathophysiological understanding of both Wolfram syndrome and mitochondrial-mediated premature aging. The knowledge of WS1 and WS2 pathogenesis, and of the interactions between WFS1 and CISD2 genes, is useful for accurate diagnostic classification and for diagnosis of presymptomatic individuals.

    2003-01-01

    Bardet-Biedl syndrome (BBS) and Usher syndrome (USH) are the most prevalent syndromic forms of retinitis pigmentosa (RP), together they make up almost a quarter of the patients with RP. BBS is defined by the association of retinopathy, obesity, hypogonadism, renal dysfunction, postaxial polydactyly and mental retardation. This clinically complex syndrome is genetically heterogeneous with linkage to more than 6 loci, and 4 genes have been cloned so far. Recent molecular data present evidence that, in some instances, the clinical manifestation of BBS requires recessive mutations in 1 of the 6 BBS loci plus one or two additional mutations in a second BBS locus (tri- or tetra-allelic inheritance). USH is characterized by the combination of congenital or early-onset sensorineural deafness, RP, and variable degrees of vestibular dysfunction. Each of the three clinical types is genetically heterogeneous: 7 loci have been mapped for type 1, three loci for type 2, and two loci for type 3. Currently, 6 USH genes (MYO7A, USH1C, CDH23, PCDH15, USH2A, USH3) have been identified. Pathogenetically, mutations of the USH1 genes seem to result in defects of auditory and retinal sensory cells, the USH 2 phenotype is caused by defects of extracellular matrix or cell surface receptor proteins, and USH3 may be due to synaptic disturbances. The considerable contribution of syndromic forms of RP requires interdisciplinary approaches to the clinical and diagnostic management of RP patients.

  13. Redefining syndromic surveillance

    Directory of Open Access Journals (Sweden)

    Rebecca Katz

    2011-12-01

    Full Text Available With growing concerns about international spread of disease and expanding use of early disease detection surveillance methods, the field of syndromic surveillance has received increased attention over the last decade. The purpose of this article is to clarify the various meanings that have been assigned to the term syndromic surveillance and to propose a refined categorization of the characteristics of these systems. Existing literature and conference proceedings were examined on syndromic surveillance from 1998 to 2010, focusing on low- and middle-income settings. Based on the 36 unique definitions of syndromic surveillance found in the literature, five commonly accepted principles of syndromic surveillance systems were identified, as well as two fundamental categories: specific and non-specific disease detection. Ultimately, the proposed categorization of syndromic surveillance distinguishes between systems that focus on detecting defined syndromes or outcomes of interest and those that aim to uncover non-specific trends that suggest an outbreak may be occurring. By providing an accurate and comprehensive picture of this field’s capabilities, and differentiating among system types, a unified understanding of the syndromic surveillance field can be developed, encouraging the adoption, investment in, and implementation of these systems in settings that need bolstered surveillance capacity, particularly low- and middle-income countries.

    2006-09-01

    Full Text Available Abstract Plummer-Vinson or Paterson-Kelly syndrome presents as a classical triad of dysphagia, iron-deficiency anemia and esophageal webs. Exact data about epidemiology of the syndrome are not available; the syndrome is extremely rare. Most of the patients are white middle-aged women, in the fourth to seventh decade of life but the syndrome has also been described in children and adolescents. The dysphagia is usually painless and intermittent or progressive over years, limited to solids and sometimes associated with weight loss. Symptoms resulting from anemia (weakness, pallor, fatigue, tachycardia may dominate the clinical picture. Additional features are glossitis, angular cheilitis and koilonychia. Enlargement of the spleen and thyroid may also be observed. One of the most important clinical aspects of Plummer-Vinson syndrome is the association with upper alimentary tract cancers. Etiopathogenesis of Plummer-Vinson syndrome is unknown. The most important possible etiological factor is iron deficiency. Other possible factors include malnutrition, genetic predisposition or autoimmune processes. Plummer-Vinson syndrome can be treated effectively with iron supplementation and mechanical dilation. In case of significant obstruction of the esophageal lumen by esophageal web and persistent dysphagia despite iron supplementation, rupture and dilation of the web are necessary. Since Plummer-Vinson syndrome is associated with an increased risk of squamous cell carcinoma of the pharynx and the esophagus, the patients should be followed closely.

    Lambers, Wietske M; Kraaijenbrink, Bastiaan; Siegert, Carl E H

    2015-01-01

    The refeeding syndrome may occur during reintroduction of carbohydrates in malnourished patients. This syndrome is characterized by reduced plasma electrolyte levels, hypophosphataemia being most prevalent. The symptoms can vary from minor symptoms to severe neurological or cardiac symptoms. The pathophysiological mechanism comprises an increase in insulin levels, resulting in shifts of phosphate, potassium and magnesium into the intracellular environment, as well as fluid retention and relative deficiency of vitamin B1. There is growing interest in the screening and treatment of patients with malnutrition, due to which the incidence of refeeding syndrome is probably increasing. Currently, there is no single definition of this syndrome and therefore there is no solid scientific basis for screening and treatment. In this article we describe the rationale for screening and additional laboratory investigations. A prospective, controlled trial is important to define the clinical relevance of the refeeding syndrome and optimize its treatment.

    Science.gov (United States)

    Bogduk, N

    1980-11-15

    Low back pain, referred pain in the lower limbs, and spasm of the back, gluteal, and hamstring muscles are clinical features which can be induced in normal volunteers by stimulating structures which are innervated by the lumbar dorsal rami. Conversely, they can be relieved in certain patients by selective interruption of conduction along dorsal rami. These facts permit the definition of a lumbar dorsal ramus syndrome, which can be distinguished from the intervertebral disc syndrome and other forms of low back pain. The distinguishing feature is that, in lumbar dorsal ramus syndrome, all the clinical features are exclusively mediated by dorsal rami and do not arise from nerve-root compression. The pathophysiology, pathology, and treatment of this syndrome are described. Recognition of this syndrome, and its treatment with relatively minor procedures, can obviate the need for major surgery which might otherwise be undertaken.

    Heterogeneity of Waardenburg syndrome is demonstrated in a review of 1,285 patients from the literature and 34 previously unreported patients in five families in the Netherlands. The syndrome seems to consist of two genetically distinct entities that can be differentiated clinically: type I, Waardenburg syndrome with dystopia canthorum; and type II, Waardenburg syndrome without dystopia canthorum. Both types have an autosomal dominant mode of inheritance. The incidence of bilateral deafness in the two types of the syndrome was found in one-fourth with type I and about half of the patients with type II. This difference has important consequences for genetic counseling. Images Fig. 7 Fig. 8 Fig. 9 PMID:331943

    The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standardized and should be individualized and monitored by a multidisciplinary team. We report a typical case in a 30-year-old man with multiple basal cell carcinomas, keratotic pits of palmar creases and bifid ribs, with a history of several corrective surgeries for keratocystic odontogenic tumors, among other lesions characteristic of the syndrome.

    Antiphospholipid syndrome is revealed by Budd Chiari syndrome in 5% of the cases. Antiphospholipid syndrome is characterized by venous or arterial thrombosis, foetal loss and positivity of antiphospholipid antibodies, namely lupus anticoagulant, anticardiolipin antibodies and anti-beta2-glycoprotein I. Anticardiolipin antibodies was reported in auto-immune thyroid disorders, particularly in Grave's disease. Antiphospholipid syndrome associated to Grave's disease was reported in only three cases. To describe a case report of association of Grave's disease and antiphospholipid syndrome. We report the first case of Grave's disease associated with antiphospholipid syndrome, revealed by Budd Chiari syndrome. Our observation is particular by the fact that it is about a patient presenting a Grave's disease associated with antiphospholipid syndrome revealed by Budd Chiari syndrome. This triple association has never been reported in literature. Although association between antiphospholipid syndrome and Grave's disease was previously described, further studies evaluating the coexistence of these two affections in the same patient would be useful.

  5. The Marfan syndrome genetics

    Directory of Open Access Journals (Sweden)

    Galina Pungerčič

    2005-05-01

    Full Text Available Background: The Marfan syndrome is an autosomal dominant heritable disorder of connective tissue. It is caused by mutations in the fibrillin-1 gene encoding glycoprotein fibrillin-1, a component of microfibrils of extracellular matrix. Patients with Marfan syndrome show wide spectra of clinical signs, primarily on skeletal, cardiovascular and ocular organ systems. Cardiovascular complications (especially aortic aneurysm and aortic dissection are the most common cause of mortality of Marfan syndrome patients. Discovering genotype-phenotype correlations is complicated because of the large number of mutations reported as well as clinical heterogeneity among individuals with the same mutation. Despite the progress in the knowledge of the molecular nature of Marfan syndrome the diagnosis is still based mainly on the clinical features in the different body systems.Conclusions: Early identification of patient with Marfan syndrome is of considerable importance because of appropriate treatment that can greatly improve life expectancy. Unfortunately, despite the improvement of diagnostic methods, medical and surgical therapy, the mortality due to undiagnosed Marfan syndrome is still high. The present article reviews the molecular genetic studies of Marfan syndrome since the discovery of the mutations in the fibrillin-1 gene.

  6. Loin pain hematuria syndrome.

    2014-09-01

    Loin pain hematuria syndrome is a rare disease with a prevalence of ∼0.012%. The most prominent clinical features include periods of severe intermittent or persistent unilateral or bilateral loin pain accompanied by either microscopic or gross hematuria. Patients with loin pain hematuria syndrome initially present with hematuria, flank pain, or most often both hematuria and flank pain. Kidney biopsies from patients with loin pain hematuria typically reveal only minor pathologic abnormalities. Further, loin pain hematuria syndrome is not associated with loss of kidney function or urinary tract infections. Loin pain hematuria syndrome-associated hematuria and pain are postulated to be linked to vascular disease of the kidney, coagulopathy, renal vasospasm with microinfarction, hypersensitivity, complement activation on arterioles, venocalyceal fistula, abnormal ureteral peristalsis, and intratubular deposition of calcium or uric acid microcrystals. Many patients with loin pain hematuria syndrome also meet criteria for a somatoform disorder, and analgesic medications, including narcotics, commonly are used to treat loin pain hematuria syndrome-associated pain. Interventional treatments include renal denervation, kidney autotransplantation, and nephrectomy; however, these methods should be used only as a last resort when less invasive measures have been tried unsuccessfully. In this review article, we discuss and critique current clinical practices related to loin pain hematuria syndrome pathophysiology, diagnosis, treatment, and prognosis.

    Full Text Available Audience: This scenario was developed to educate emergency medicine residents on the diagnosis and management of a pediatric patient with toxic shock syndrome. The case is also appropriate for teaching of medical students and advanced practice providers, as well as a review of the principles of crisis resource management, teamwork, and communication. Introduction: Toxic shock syndrome is a low-frequency, high-acuity scenario requiring timely identification and aggressive management. If patients suffering from this condition are managed incorrectly, they may progress into multi-organ dysfunction and potentially death. Toxic shock syndrome has been associated with Streptococcus and Staphylococcus aureus (Staph. Approximately half of Staph cases are associated with menstruation, which was first described in the 1970s-1980s and was associated with the use of absorbent tampons.1 Group A Streptococcus may cause complications such as necrotizing fasciitis and gangrenous myositis.2 Pediatric patients may present critically ill from toxic shock syndrome. Providers need to perform a thorough history and physical exam to discern the source of infection. Management requires aggressive care with antibiotics and IV fluids. Objectives: By the end of this simulation session, the learner will be able to: 1 Recognize toxic shock syndrome. 2 Review the importance of a thorough physical exam. 3 Discuss management of toxic shock syndrome, including supportive care and the difference in antibiotic choices for streptococcal and staphylococcal toxic shock syndrome. 4 Appropriately disposition a patient suffering from toxic shock syndrome. 5 Communicate effectively with team members and nursing staff during a resuscitation of a critically ill patient. Method: This session was conducted using high-fidelity simulation, followed by a debriefing session and lecture on toxic shock syndrome.

    The Norrie syndrome, an x-chromosomal linked, recessive genetic disease, is described using ophthalmologic and genetic examinations of a family in three generations. The main symptom of this syndrome is retinal detachment with hemorrhages, which generally leads to blindness in early childhood. In addition to this, in 25--35% of the cases mental retardation and hearing problems are found. Special significance is to be attached to the differential diagnosis of this syndrome because the vascular proliferation on the retina is a non-specific, secondary reaction in children, which also occurs symptomatically in several other diseases.

    The refeeding syndrome is frequent and potentially deadly, still it is underdiagnosed. It is defined by clinical and biological manifestations that are seen upon refeeding of malnourished patients. It is the consequence of the transition from catabolism to anabolism. Ions intracellular shift caused by insulin and B1 vitamin deficiency are fundamental in the development of this syndrome. Riskconditions are well summarized by the NICE criteria. To avoid refeeding syndrome, it is fundamental to find and correct any electrolytic deficiency and to give thiamine before starting a slow and progressive oral, enteral or parenteral refeeding.

    Stendhal's syndrome occurs among travelers when they encounter a work of art of great beauty. It is characterized by an altered perception of reality, emotional disturbances, and crises of panic and anxiety with somatization. The patient profile described originally for this syndrome was of particularly sensitive individuals who were admirers of works or art: artists, poets, writers and art students, among others. The Russian writer Fyodor Mikhailovich Dostoevsky suffered from epilepsy and there is evidence that he presented the symptoms of Stendahl's syndrome while contemplating some works of art, particularly when viewing Hans Holbein's masterpiece, Dead Christ, during a visit to the museum in Basle.

    It is not common for a patient who survives cardiac arrest to experience significant neurologic impairment such as acute and chronic post-hypoxic myoclonus, known as Lance-Adams syndrome. This syndrome is predominantly characterized by myoclonus that starts days to weeks after cardiopulmonary resuscitation in patients who regained consciousness. Although several cases of LAS were reported, the decisive treatment method has not been established. We report a 43 year old man with Lance-Adams syndrome who showed long-term improvement through treatment with anti-myoclonic agents and participation in a rehabilitation program.

    Full Text Available Ehlers-Danlos syndrome is a group of clinically and genetically heterogeneous inherited connective tissue disorders with widespread manifestations. The prevalence of this syndrome is 1:5000 worldwide without gender, racial or ethnic associations. This syndrome is characterized by joint hypermobility, dermal hyperelasticity and tissue fragility caused by mutations in genes encoding collagen type I, III, V and enzymes involved in the posttranslational modifications of collagen. The oral manifestations include increased mucosal fragility, delayed wound healing, early onset generalized periodontitis and temporomandibular joint hypermobility. Children presenting with this syndrome are often misdiagnosed for hematological problem as they present with bruising, malignancy and/or child abuse. A thorough assessment of the patient is, therefore, essential for early diagnosis and patient referral. This paper reviews current literature, oral manifestations, diagnostic investigations and effective dental management.

    Full Text Available Gorlin-Goltz syndrome is an uncommon autosomal dominant inherited disorder, which is characterized by multiple odontogenic Keratocysts and basal cell carcinomas, skeletal, dental, ophthalmic, and neurological abnormalities, intracranial ectopic calcifications of the falx cerebri, and facial dysmorphism. Pathogenesis of the syndrome is attributed to abnormalities in the long arm of chromosome 9 (q22.3-q31 and loss or mutations of human patched gene (PTCH1 gene. Diagnosis is based upon established major and minor clinical and radiological criteria and ideally confirmed by deoxyribo nucleic acid analysis. We report a case of a 9-year-old girl presenting with three major and one minor feature of Gorlin-Goltz syndrome. Radiologic findings of the syndrome are easily identifiable on Orthopantomogram, chest X-ray, and Computed tomography scans. These investigations prompt an early verification of the disease, which is very important to prevent recurrence and better survival rates from the coexistent diseases.

    2014-12-01

    Exploding head syndrome is characterized by the perception of abrupt, loud noises when going to sleep or waking up. They are usually painless, but associated with fear and distress. In spite of the fact that its characteristic symptomatology was first described approximately 150 y ago, exploding head syndrome has received relatively little empirical and clinical attention. Therefore, a comprehensive review of the scientific literature using Medline, PsycINFO, Google Scholar, and PubMed was undertaken. After first discussing the history, prevalence, and associated features, the available polysomnography data and five main etiological theories for exploding head syndrome are summarized. None of these theories has yet reached dominance in the field. Next, the various methods used to assess and treat exploding head syndrome are discussed, as well as the limited outcome data. Finally, recommendations for future measure construction, treatment options, and differential diagnosis are provided. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Maffucci's syndrome consists of multiple cutaneous hemangiomas, dyschondroplasia, and enchondromas with potential for malignant change. We report a case of a 33-year-old man with Maffucci's syndrome who presented with a several month history of nasal congestion, facial pain, and diminished vision in his left eye. Radiological studies showed a large soft tissue mass centered in the sinonasal area, extending bilaterally into maxillary sinuses and orbits with compression of left optic nerve. Biopsy of the mass showed esthesioneuroblastoma (olfactory neuroblastoma). Chemotherapy resulted in initial improvement, but the tumor recurred and did not respond to further treatment, resulting in his death. Sarcomatous tumors are reported in Maffucci's syndrome, but this is a rare case of a neuroendocrine tumor in a patient with Maffucci's syndrome. (orig.)

    Full Text Available Children who have been programmed by one parent to be alienated from the other parent are commonly seen in the context of child-custody disputes. Its primary manifestation is the child’s campaign of denigration against a parent, a campaign that has no justification. It is said to result from a combination of a programming (brainwashing parent’s indoctrinations and the child’s own contributions to the vilification of the targeted parent. Many evaluators use the term parental alienation syndrome to refer to the disorder engendered in such children. However, there is significant controversy going on about the validity of parental alienation syndrome. The purpose of this article has been to describe and help to differentiate parental alienation syndrome and abuse for mental health professionals working in the field, and discuss the arguments about the validity of this syndrome.

    Horner syndrome consists of unilateral ptosis, an ipsilateral miotic but normally reactive pupil, and in some cases, ipsilateral facial anhidrosis, all resulting from damage to the ipsilateral oculosympathetic pathway. Herein, we review the clinical signs and symptoms that can aid in the diagnosis and localization of a Horner syndrome as well as the causes of the condition. We emphasize that pharmacologic testing can confirm its presence and direct further testing and management. PMID:28539793

    PTC or ERCP findings of four cases of Mirizzi syndrome were demonstrated. They consisted of a smooth stricture of the common hepatic duct, curved impressions of the duct and dilatation of proximal biliary radicles. CT could visualize the impacted stone in the neck of the gallbladder, dilatation of proximal common hepatic and intrahepatic duct. Absence of the dilatation of distal common bile duct could also be confirmed by CT, thus the diagnosis of Mirizzi syndrome might be possible by CT. (author)

    We recently managed a patient with the HELLP syndrome (Haemolysis, Elevated Liver enzymes and Low Platelet count) where there was a delay in diagnosis due to gastroenteritis. This case also reiterates the varied or lack of symptomatology in patients developing HELLP and obscuring the initial diagnosis. Patients with HELLP syndrome have significant maternal morbidity and mortality, hence clinical vigilance and high suspicion play a key role in the diagnosis and subsequent management.
