BACKGOUND: Gitelman's syndrome is manifested by hypokalemia, metabolic alkalosis, normal blood pressure, hyperreninemic hyperaldosteronism, hypomagnesemia and hypocalciuria. This study was carried out to investigate the effects of magnesium supplementation for correcting hypokalemia in Gitelman syndrome. METHODS: A Gitelman patient without hyperaldosteronism in our hospital was studied, oral supplementation periods of regimens for 60 days were divided into eight stages (each stage is at least over 5 days) such as 1 stage:no regimen supplementation period 2 stage:spironolactone 100 mg, alone period 3 stage:spironolactone 100 mg, MgO 1 g mixed period, 4 stage:spironolactone 100 mg, alone period, 5 stage:spironolactone 100 mg, MgO 1 g mixed period, 6 stage:spironolactone 150 mg, MgO 1 g mixed period, 7 stage: spironolactone 150 mg, MgO 1.5 g mixed period, 8 stage:spironolactone 150 mg, MgO 1.5 g, KCl 3.6 g mixed period. RESULTS: The highest value of plasm [K] was 3.3 mEq/L, the lowest value of TTKG was 2.6 during 3 stage, plasm [K] had tendency to increased and TTKG decreased, however next during 4 stage, the tendency of correcting hypokalemia diminished. The highest value of plasm [K] was only 3.3 mEq/L during 7 stage, the highest value of plasm [K] was 4.6 mEq/L during 8 stage. And the highest value of plasm ionized [Mg++] was 0.44 mmol/L during MgO 1.5 g supplementation. CONCLUSION: Magnesium alone fails to completely correct potassium and magnesium depletion despite tendency of correcting. Therefore, the optimal therapeutic regimens for correcting hypokalemia in Gitelman syndrome without hyperaldosteronism would be the magnesium and additional K supplementation.

Gitelman's sydnrome is a heritable renal disorder characterized by hypomagnesemia, hypokalemia and hypocalciuria. As compared to those with Bartter's syndrome, reduced urinary excretion of calcium and magesium wasting are essential features of Gitelman's syndrome. Interestingly, we have experienced a case of 32-year old man with a mixed type of Gitelman's syndrome and Bartter's syndrome, which includes normomagnesemia, normal renal magnesium excretion, and hypocalciuria. Herein we report the case of atypical Gitelman's syndrome with brief review of related literature.

Gitelman's syndrome is a heritable renal disorder characterized by hypomagnesemia, hypokalemia and hypocalciuria. Interestingly, we have experienced one patient who had chronic hypotension, normal serum magnesium level, normal plasma ionized magnesium level, hypokalemia and hypocalciuria. Immunohistochemistry showed the absence of NCCT staining in renal tissues of the patient. We report the case of atypical Gitelman's syndrome with a brief review of related literature.

6.Recurrent hypokalemia in an adult male: A case report on gitelman’s syndrome

Introduction:
Gitelman Syndrome (GS), a rare autosomal recessive inherited disorder, is frequently unrecognized in the
clinical setting. GS typically manifests with severe hypokalemia with debilitating and potentially fatal consequences if
untreated. As of writing, confirmatory genetic assays are currently unavailable in the country, and the diagnosis of GS is
primarily based on several biochemical laboratory tests. This results in the difficulty with prompt diagnosis of GS in the
locality.
Case:
We present a 52-year-old male who came in with chronic, intermittent paraparesis associated with persistent
hypokalemia. A diagnosis of GS was made biochemically based on renal wasting of potassium and magnesium,
hypocalciuria, and metabolic alkalosis. Electrolyte correction with lifelong supplementation, and administration of
Spironolactone resulted in the resolution of bilateral leg weakness. Electrolyte levels were maintained within normal limits
in the outpatient setting.
Conclusion
GS is an uncommon potentially debilitating disorder that may lead to problematic, potentially fatal
consequences to electrolyte abnormalities if left untreated. The lack of awareness and consequent delay in the diagnosis,
and the unavailability of confirmatory genetic testing remains a clinical challenge. Timely recognition and initiation of
treatment leads to early control of electrolyte levels, and better prognosis.

7.Acquired Gitelman Syndrome.

Acquired renal tubular disorder can be observed in various disease processes, especially autoimmune diseases. Gitelman syndrome is an autosomal recessive disease characterized by hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria. This disorder is caused by mutation in the SLC12A3 gene, which encodes the thiazide - ensitive NaCl cotransporter (NCCT). Acquired Gitelman syndrome has been reported and the majority has been associated with Sjogren's syndrome. The presence of circulating auto - antibodies to NCCT was suggested as a mechanism of acquired Gitelman syndrome. Treatment of acquired Gitelman syndrome was done with supplements of potassium and magnesium and prednisone was effective in some cases. Acquired Gitelman syndrome should be included in the differential diagnosis of renal involvement in patients with autoimmune diseases, especially Sjogren's syndrome.

Both Gitelman syndrome and Bartter syndrome are autosomal recessively inherited renal tubular disorders characterized by hypokalemic metabolic alkalosis, salt wasting and normal to low blood pressure. Gitelman syndrome is caused by mutations in the thiazide-sensitive Na- Cl cotransporter (NCCT) and distinguished from Bartter syndrome, which is associated with mutations of several genes, by the presence of hypomagnesemia and hypocalciuria. In most of the patients with Gitelman syndrome, the disease manifests with transient episodes of muscular weakness and tetany in the adult period, but, often, is asymptomatic. We report here an 11 years-old female with Gitelman syndrome who presented with aggravation of epileptic seizure. The diagnostic work-up showed typical clinical features of metabolic alkalosis, hypokalemia, hypomagnesemia and hypocalciuria. We also identified a heterozygote mutation(642CGC(Arg)>TGC(Cys)) and an abnormal splicing in the SLC12A3 gene encoding NCCT.

Gitelman's syndrome is an autosomal recessive disorder characterized by hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria that has recently been reported to be linked to thiazide-sensitive Na-Cl cotransporter gene mutation. We have experienced one patient whose initial complaint was paresthesia of hand and feet, who had hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria. We report the case of Gitelman's syndrome with a brief review of related literature.

We have experienced two patients who had hypokalemic metabolic alkalosis as well as hypomagnesemia and hypocalciuria with elevated plasma renin activity. We have performed renal clearance study after water loading, administration of furosemide and thiazide in two patients and two normal controls. Maximal free water clearance per 100 mL glomerular filtration rate(CH2O) and distal fractional chloride reabsorption[CH2O/(CH2O+CCl)] in our patients were reduced than the controls. Chloride clearance(CCl) was increased after furosemide administration but not after thiazide administration. Distal fractional chloride reabsorption[CH2O/(CH2O+CCl)] was dramatically decreased by furosemide administration in our patients, whereas thiazide had little effect on it. Fractional excretion of sodium, chloride, magnesium, calcium was increased by furosemide administration, whereas thiazide administration had little effect on this parameters. These findings suggested the presence of a defect in the distal convoluted tubule rather than in the thick ascending loop of Henle. Herein, we report two cases of Gitelman's syndrome diagnosed by renal clearace study after water loading, administration of furosemide and thiazide.
