Presentation
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]
Childhood presentation of distal RTA includes vomiting, failure to thrive, metabolic acidosis, and hypokalemia. [indianjnephrol.org]
Entire Body System
- Pallor
General examination revealed mild pallor and normal vital parameters. Examination of the central nervous system revealed hypotonia with grade 3 power, proximally and distally, in all four limbs. No neck muscle weakness was present. [mjdrdypu.org]
The hydropic female newborn had intense pallor, generalized edema, prominent ascites, and massive hepatosplenomegaly (weight, 2445 g; Apgar scores, 2, 8, and 9). [bloodjournal.org]
In undiagnosed renal failure there may be dryness of mouth, eyes and skin, scratch marks on skin, pallor, drowsiness and fetor. [patient.info]
Gastrointestinal
- 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]
Cardiovascular
- Hypotension
[…] cotransporter in the distal convoluted tubule → impaired Na + and Cl - reabsorption → mild natriuresis → mild volume depletion → mild RAAS activation Clinical features Fatigue, muscle weakness Muscle cramps and/or tetany Mild polyuria Possibly, mild hypotension [amboss.com]
Presentation of cardiac toxicities of organophosphates may be of three types. [2] It may be intense sympathetic activity due to nicotinic effect producing tachycardia and hypertension or muscarinic activity producing bradycardia and hypotension. [ijccm.org]
Check vital signs, as hypotension may occur due to myocardial suppression in severe acidaemia. Tachypnoea is likely to be present. [patient.info]
Psychiatrical
- Withdrawn
The clinical diagnosis of DRTA in this patient is supported by the presence of hypercloremic metabolic acidosis during a long-term follow-up when alkali treatment was transiently withdrawn and by the presence of SNHL and nephrocalcinosis. [nature.com]
Neurologic
- Irritability
At 2 months of age, the infant had persistent failure to thrive and a 1-day history of irritability and vomiting and was readmitted for diagnostic evaluation. [pedsinreview.aappublications.org]
These include sicca symptoms (dryness and irritation of eyes, dysphagia, dental caries, hoarseness of voice), musculoskeletal symptoms (fatigue, arthralgia), nephrocalcinosis and chronic kidney disease and a greater propensity to develop lymphoid malignancies [mjdrdypu.org]
Urogenital
- 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]
Workup
[…] incomplete and only develop in the presence of an acid load occurs despite a normal or only mildly reduced glomerular filtration rate (GFR) causes are numerous poorly understood by many physicians RTA is often detected incidentally through an abnormal blood workup [lifeinthefastlane.com]

X-Ray
- 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]
Urine
- Glycosuria
Fanconi's syndrome, with generalized proximal tubular dysfunction, causes glycosuria, aminoaciduria, hypophosphatemia, and rickets. [nmckk.jp]
Glycosuria See separate Glycosuria article. Nephrogenic diabetes insipidus See also separate Diabetes Insipidus article. Caused by renal insensitivity to antidiuretic hormone. [patient.info]
There was no glycosuria or proteinuria. The urinary potassium level was 24 meq/l, which indicates renal potassium wasting (exceeding 20 meq/l). [indianjnephrol.org]
Serum
- Hyperchloremia
Based on clinical findings (delayed growth and O-bein deformity) and laboratory tests (hypokalemia, hyperchloremia, partially compensated metabolic acidosis, alkaline urine and nephrocalsinosis), a diagnosis of distal renal tubular acidosis (dRTA) was [ncbi.nlm.nih.gov]
Features Chronic metabolic acidosis with hyperchloremia and normal anion gap. Urinary pH is usually over 5.5 although acidemia with normal glomerular function. [renaltube.com]
Idiopathic (Sporadic) Type 1 Distal Renal Tubular Acidosis Physiology Impaired distal tubular H+ secretion/ excessive back-diffusion of H+ in collecting duct (by intercalated cells) Renal bicarbonate loss: bicarbonate is replaced by chloride (produces hyperchloremia [mdnxs.com]

QT, RR, ST Intervals
- 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
Treatment to correct the acidosis and hyperkalemia should be promptly initiated, and the tacrolimus dose adjusted when possible. [ncbi.nlm.nih.gov]
From review of pediatrics texts from 1830 to 1850, a recommended treatment plan would have included (1) general measures such as country air and exercise, and fish oils such as cod and halibut (vitamin D), and (2) specific treatments of tonics (containing [doi.org]
Prognosis
[…] 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]

Prevention
To prevent the nephrocalcinosis from deteriorating, she was given potassium-sodium citrate. Since administration, she has not experienced spontaneous stone passage or renal colic. [ncbi.nlm.nih.gov]
Correcting acidosis and low potassium levels restores normal growth patterns, allowing bone to mature while preventing further renal disease. Vitamin D supplements may also be needed to help prevent bone problems. [niddk.nih.gov]
