Incomplete distal renal tubular acidosis in children
Acta Paediatrica, International Journal of Paediatrics, 2020AbstractAimTo describe incomplete distal renal tubular acidosis (iDRTA) in paediatric patients, a term used for the diagnosis of patients who do not develop spontaneous overt metabolic acidosis but are unable to acidify the urine in response to an ammonium chloride load.MethodsTests used to explore urinary acidification were revised.

Hyperammonaemia in a child with distal renal tubular acidosis
Pediatric Nephrology, 2005A 5-month-old girl with distal renal tubular acidosis (RTA) and hyperammonaemia that had lasted for 12 days, despite metabolic acidosis correction, is presented in this report. The patient showed failure to thrive, poor feeding, hypotonia and vomiting crisis in absence of inborn errors of metabolism.

Distal Renal Tubular Acidosis and the Potassium Enigma
Seminars in Nephrology, 2006Severe hypokalemia is a central feature of the classic type of distal renal tubular acidosis (RTA), both in hereditary and acquired forms. In the past decade, many of the genetic defects associated with the hereditary types of distal RTA have been identified and have been the subject of a number of reviews.

"Superscan" Appearance in Distal Renal Tubular Acidosis
Clinical Nuclear Medicine, 1991Distal renal tubular acidosis (RTA) is known to cause metabolic bone abnormalities. For the first time to our knowledge, a case of distal RTA is reported in association with a superscan on bone scintigraphy. Reported cases of metabolic bone diseases producing a superscan appearance were reviewed, and underlying mechanisms are discussed.

Distal renal tubular acidosis in a cat with pyelonephritis
Veterinary Record, 1986A four-year-old castrated male domestic shorthair cat with recent onset of lethargy and depression was found to have hypokalaemia, low plasma bicarbonate concentration and a urine pH of 7. Subsequent findings of hyperchloraemic metabolic acidosis with failure to produce acid urine led to a diagnosis of distal renal tubular acidosis.

Distal Renal Tubular Acidosis: Pathogenesis and Classification
American Journal of Kidney Diseases, 1982Distal renal tubular acidosis results from ineffective addition of hydrogen ions to the lumen of the distal nephron. The syndrome is manifested by hyperchloremic metabolic acidosis often associated with hypokalemia. More recently, it has been recognized that hyperkalemia rather than hypokalemia can be a dominant feature of some cases of distal renal ...

Distal Renal Tubular Acidosis in Selective Hypoaldosteronism
Southern Medical Journal, 1978Renal mechanisms for metabolic acidosis in selective hypoaldosteronism were investigated in a patient with marked renal insufficiency. Studies demonstrated a distal hydrogen ion secretory defect. Control of elevated serum potassium levels did not normalize urinary acid excretion, but systemic acidosis was improved.

Canine Distal Renal Tubular Acidosis and Urolithiasis
Veterinary Clinics of North America: Small Animal Practice, 1986Distal RTA is characterized by decreased distal renal tubular hydrogen ion secretion, decreased ability to acidify urine, hypercalciuria, hyperphosphaturia, hypocitraturia, and metabolic acidosis. Because of the resulting alterations in urine composition and pH, patients with distal RTA are predisposed to urolithiasis and renal calcification. Diagnosis

Acidosis increases magnesiuria in children with distal renal tubular acidosis
Pediatric Nephrology, 2004In experimental animals, metabolic acidosis increases renal magnesium (Mg) excretion, whereas metabolic alkalosis reduces it. The objective of this study was to examine renal magnesium handling (U(Mg)) in children with primary distal renal tubular acidosis (DRTA).

Screening Renal Stone Formers for Distal Renal Tubular Acidosis
British Journal of Urology, 1989Summary— A group of 110 consecutive renal stone formers were screened for distal renal tubular acidosis (RTA) using morning fasting urinary pH (mfUpH) levels followed by a short ammonium chloride loading test in patients with levels above 6.0. In 14 patients (12.7%) a renal acidification defect was noted; 13 had
