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. [journal.einstein.br]

Growth faltering, dwarfism, polydipsia, and weakness may be present in older children. Mild mental retardation is reported in few patients. [hindawi.com]

Postnatally patients present with polyuria, isosthenuria/hyposthenuria and are at high risk of dehydration, hypovolemic hypotension and shock. Patients are found to have complete sensorineural deafness. [rarediseases.info.nih.gov]

Sometimes a few status may be nested, as in our case presented here. Case Report: An 8-month-old boy was referred to our hospital with of intractable diarrhea, polyuria, persistent hypokalemia, abdominal distension and failure to thrive. [amjcaserep.com]

• Falling

  Without treatment, potassium levels in the blood could fall very low without the patient being aware of it, and can cause heart rhythm problems. How the disease works Bartter Syndromes can affect boys and girls equally. [kidneycareuk.org]

  As the serum potassium and/or magnesium falls in the untreated patient, the antikaliuretic effect of hypokalemia and the antimagnesiuretic effect of hypomagnesemia gradually reduce potassium and magnesium excretion until a new steady state is attained [intechopen.com]

• Anorexia

  BS was diagnosed based on the following four criteria: (1) severe hypokalemia (<3 mEq/L), (2) metabolic alkalosis, (3) normotensive or hypotension hyperreninemic hyperaldosteronism, (4) no drug abuse (diuretics or cathartics), anorexia nervosa, or chronic [nature.com]

• Fishing

  The most commonly applied techniques to detect these mutations are fluorescent in situ hybridization (FISH) and Southern blotting. FISH analysis has been preferred because it allows for visual determination of the copy number in the region examined. [nature.com]

• Recurrent Vomiting

  Recurrent vomiting, muscle cramps, spasms and failure to thrive are observed. Progression to renal failure is frequent. Hypokalemic alkalosis, hypomagnesemia, hyperprostaglandin E-uria and hypochloremia are noted (hypercalciuria is only transient). [rarediseases.info.nih.gov]

• Abdominal Pain

  Sometimes high doses are needed which can be difficult to digest and may cause unpleasant side effects like abdominal pains and diarrhoea. SlowK and Kay-Cee-L Liquid are preferable to SandoK. [kidneycareuk.org]

  After 10 years of long-term treatment with indomethacin, the child began to show adverse effects including upper abdominal pain with acid regurgitation, nausea, and vomiting. [journals.sagepub.com]

• Abdominal Distension

  Case Report: 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. [amjcaserep.com]

• Normal Hearing

  CLCKa is highly expressed in the inner ear and contributes to maintain the high potassium ion concentration in the endolymph necessary for normal hearing, disruption of the function of which thus leads to nerve deafness. [rarediseases.info.nih.gov]

• Impulsivity

  This deafness is of sensori-neural type, the problem being in translating the vibration of sound into nerve impulses in the inner ear. [kidneycareuk.org]

  One of the different functions of the kidney is maintaining a specific volume and composition of body fluids through the reabsorption of salts and minerals that conduct electrical impulses in the body (electrolytes). [rarediseases.org]

• Polyuria

  Postnatally patients present with polyuria, isosthenuria/hyposthenuria and are at high risk of dehydration, hypovolemic hypotension and shock. Patients are found to have complete sensorineural deafness. [rarediseases.info.nih.gov]

• Kidney Failure

  Kidney function is also normal if the disease is treated,[3] but occasionally patients proceed to end-stage kidney failure. [en.wikipedia.org]

Clinical Testing and Workup Laboratory tests that are used to diagnose these disorders include blood tests to determine serum electrolyte levels, specifically potassium, chloride, bicarbonate, magnesium, renin, and aldosterone levels and urine tests to [rarediseases.org]

• Hyponatremia

  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. [amjcaserep.com]

  (b) The patient had severe hypokalemia, hyponatremia, and hypochlorinemia, but these abnormalities improved after treatment with a non-steroidal anti-inflammatory drug and potassium supplementation. [journals.sagepub.com]

• Erythrocytosis

  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. [journal.einstein.br]

It is therefore important to remain on the correct amount of treatment to balance the body’s salt levels and prevent complications. [kidneycareuk.org]

The patient maintained normal growth and development after treatment (Figure 1(c)). Indomethacin was selected for this patient’s treatment because it is small enough to be crushed and dissolved in milk for infants to drink. [journals.sagepub.com]

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. [amjcaserep.com]

Standard Therapies Treatment The treatment of the Bartter syndromes is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. [rarediseases.org]

Caution in such treatment is required as treatment with potassium sparing diuretics may be dangerous in situations of gross salt and water wasting and circulatory volume contraction. Long-term prognosis is guarded. [hindawi.com]

Long-term prognosis is guarded. Lack of satisfactory control may lead to morbidity, growth failure, and renal insufficiency [2, 18, 23]. 8. Prognosis Untreated ABS patients may succumb to dehydration, dyselectrolytemia, and intercurrent infections. [hindawi.com]

Prognosis and Patient Counseling. Both Bartter and Gitelman syndromes are autosomal recessive inherited disorders, and genetic counseling of parents with an affected child is important. [cancertherapyadvisor.com]

With early treatment of the electrolyte imbalances, the prognosis for patients with classic Bartter Syndrome is good.[citation needed] History[edit] The condition is named after Dr. Frederic Bartter, who, along with Dr. [en.wikipedia.org]

Thus, we conclude that even with type III BS, active treatment can improve the patient’s height, weight, and biochemical indicators; maintain normal growth and development in children; and provide a comfortable prognosis. [journals.sagepub.com]

Etiology Infantile Bartter syndrome with deafness is caused by a defect in chloride transport in thick ascending loop of Henle and distal convoluted tubule as a consequence of inactivating mutations of the gene BSND (1p32.3) encoding for the protein Barttin [rarediseases.info.nih.gov]

Epidemiology It is the least common of all recessive types of Bartter syndrome. [rarediseases.info.nih.gov]

Last, the nonsense mutation Q32X allowed barttin to associate with ClC-K channels but prevented surface membrane insertion and channel activation. [jasn.asnjournals.org]

These drugs can prevent the secretion of aldosterone from the adrenal glands and counteract the effects of renin on the kidneys, thereby reducing potassium and acid loss. [rarediseases.org]
