By presenting this case we aim to not only highlight one of the rare presentations of Sjogren's syndrome but also the favourable response of our patient to potassium replacement alone. [ncbi.nlm.nih.gov]

• Poor Feeding

  The patient showed failure to thrive, poor feeding, hypotonia and vomiting crisis in absence of inborn errors of metabolism. [ncbi.nlm.nih.gov]

• Failure to Thrive

  We suggest that RTA be considered a diagnostic possibility in all children with failure to thrive and nephrocalcinosis. [ncbi.nlm.nih.gov]

• Vomiting

  Since causes of nausea and vomiting among HIV/AIDS patients are very diverse, awareness of this phenomenon is useful in diagnosing and managing the problem. [ncbi.nlm.nih.gov]

• Nausea

  Since causes of nausea and vomiting among HIV/AIDS patients are very diverse, awareness of this phenomenon is useful in diagnosing and managing the problem. [ncbi.nlm.nih.gov]

  The patient denied associated fever, nausea, vomiting, diarrhea, or recent illness prior to this admission. She noted recent polyuria prior to presentation, but denied dysuria or hematuria. [shmabstracts.com]

  For some kids, the first symptom of RTA is kidney stones, which can cause symptoms like: pain in the back or side that spreads to the lower abdomen pain while urinating pee that is red, brown, or cloudy frequent urge to urinate nausea and vomiting Over [kidshealth.org]

  Confusion Nausea Fatigue Vomiting ( 10 ). If your child experiences pain during urination, needs to urinate frequently, has cloudy or red/brown urine then these could be signs of kidney stones and hence RTA. [momjunction.com]

  Nausea, vomiting and anorexia are frequently present, particularly in children. Metabolic acidosis occurring in children is very rarely due to an inborn error of metabolism (conditions such as moderately severe gastroenteritis being more common). [patient.info]

• Normal Hearing

  Additionally, in a possible case of autosomal recessive dRTA with normal hearing, mutational analysis of ATP6V0A4 gene may be recommended first to confirm the diagnosis. [ncbi.nlm.nih.gov]

• Progressive Hearing Loss

  We identified two novel ATP6V0A4 mutations in a Chinese patient with distal renal tubular acidosis and late onset hearing loss, and presented the first direct evidence of progressive hearing loss associated with ATP6V0A4 mutations by sequential audiological [ncbi.nlm.nih.gov]

• Proximal Muscle Weakness

  Hypokalemic paralysis, proximal muscle weakness and voiding difficulty were the common modes of presentation. Doubling of serum creatinine during the study period was noted in 13 out of 27 patients who had GFR 60 mL/min (P [ncbi.nlm.nih.gov]

• Prominent Cheeks

  Their facial features are unique with prominent cheeks, well-defined philtrum, large bulbous nose, V-shaped upper lip border, full lower lip, open mouth with protruded tongue, and pits on the ear lobule. [ncbi.nlm.nih.gov]

• Bulbous Nose

  Their facial features are unique with prominent cheeks, well-defined philtrum, large bulbous nose, V-shaped upper lip border, full lower lip, open mouth with protruded tongue, and pits on the ear lobule. [ncbi.nlm.nih.gov]

• Nocturia

  Symptoms of renal failure such as nocturia, polyuria, oliguria, pruritus and anorexia. Recent history of urinary problems such as nephrolithiasis may indicate RTA. Recent history of severe or prolonged diarrhoea. Recent nutritional status. [patient.info]

• Nephrolithiasis

  This is the first demonstration of renal acidification defects and nephrolithiasis in heterozygous carriers of a mutant B1 subunit that cannot be attributable to negative dominance. [ncbi.nlm.nih.gov]

  Nephrolithiasis, which may occur in any of the subsets of type I renal tubular acidosis, accounts for most of the morbidity in adults and adolescents. Major risk factors for nephrolithiasis include alkaline urine, hypercalciuria and hypocitraturia. [doi.org]

• Small Kidney

  Renal ultrasound examinations revealed small kidneys, with varying degrees of hyperechogenicity and nephrocalcinosis. Additional findings included dilated ventricles and cerebral demyelination on brain imaging studies. [ncbi.nlm.nih.gov]

• Increased Bone Density

  Clinical manifestations of this autosomal recessive syndrome comprise increased bone density, growth failure, intracerebral calcification, facial dysmorphism, mental retardation, and conductive hearing impairment. [ncbi.nlm.nih.gov]

• Prolonged QT Interval

  Electrocardiogram showed rate 140/min, electrical alternans, multifocal ventricular ectopics, ventricular reentrant beats, ventricular couplets, and prolonged qT interval (corrected qT = 512 ms). Echocardiogram was normal. [ijccm.org]

  Serum level of potassium was 1.5 meq/l and electrocardiogram showed prolonged QT interval, ST depression, T wave flattening in V1-V4, and the presence of 'U' waves. Child was given potassium replacement therapy and recovered from paralysis. [indianjnephrol.org]

Treatment to correct the acidosis and hyperkalemia should be promptly initiated, and the tacrolimus dose adjusted when possible. [ncbi.nlm.nih.gov]

Management and treatment Alkali therapy is the standard treatment (to achieve normal serum bicarbonate levels). Patients are usually given sodium bicarbonate or sodium citrate. [orpha.net]

Treatment in the initial phase consists of alkalising agents such as bicarbonate or citrate and correction of the hypokalaemia. [revistanefrologia.com]

[…] distal renal tubular acidosis (dRTA) presents itself with variable clinical manifestations and often with late expressions that impact on prognosis. [ncbi.nlm.nih.gov]

Prognosis Hereditary dRTA is a permanent circumstance, with an excellent prognosis if therapy is established as soon as possible. Complications Chronic renal failure can be a complication of untreated nephrocalcinosis. [renaltube.com]

In dRTA, the potassium level can be low, normal, or even high depending upon the pathophysiologic abnormality. Early recognition and prompt treatment is imperative to avoid the serious consequences of severe electrolyte and metabolic disturbances. [sciencedomain.org]
