Objectives: We report a case of an infant with nephrogenic diabetes insipidus (NDI) diagnosed by the measurement of serum copeptin. There is only one study that previously evaluated the use of copeptin measurement in a pediatric patient.
Case Presentation: We present a 10-month-old child with polyuria-polydipsia syndrome (PPS) and hypernatremia that could not support water restriction due to increased risk of dehydration and worsening of his condition. Therefore, plasma measurement of copeptin allowed the diagnosis of NDI.
Conclusions: The water deprivation test (WDT) is considered the gold standard for diagnosis in PPS. However, WDT has serious limitations regarding its interpretation. Furthermore, the WDT can cause dehydration and hypernatremia, especially in young children. Therefore, the measurement of plasma copeptin seems to be a promising method to perform an earlier, safer, and accurate investigation of PPS. Up to now, our study is the second to report the usefulness of copeptin in children.

The renal tubule and collecting duct express a large number of proteins, all having putative immunoreactive motives. Therefore, all can be the target of pathogenic autoantibodies. However, autoimmune tubulopathies seem to be rare and we hypothesize that they are underdiagnosed.

Background: Zoledronic acid (ZA) is widely used for the treatment of osteolytic bone metastases in malignancies and osteoporosis, but it has been associated with renal impairment. In this study, we investigated adverse events (AEs) related to renal and urinary system diseases associated with ZA using the U. S.

Nephrogenic diabetes insipidus (NDI) results from the kidneys' inability to concentrate urine. We describe a 6-month-old male with a history of poor weight gain who presented with an incidental finding of hypernatremia (155 mEq/L) during an episode of acute gastroenteritis. The arginine vasopressin (AVP) test, along with molecular analysis revealing the M272R mutation in the AVP receptor 2 (AVPR2) gene, confirmed the diagnosis of congenital NDI.

Article Synopsis
- The study aimed to identify genetic factors contributing to treatment-resistant nocturnal enuresis in children who had already undergone various therapies.
- Twenty-one patients aged 5-18 with treatment-resistant enuresis were analyzed using a specialized genetic panel that included 19 genes associated with the condition.
- Results showed that 20 patients had no significant genetic changes, while one patient had a variant in the AQP2 gene, suggesting that nocturnal enuresis is likely influenced by multiple factors rather than a single genetic cause.
