Congenital Nephrogenic Diabetes Insipidus

Abstract. Congenital nephrogenic diabetes insipidus is characterized by insensitivity of the distal nephron to arginine vasopressin. Clinical knowledge of this disease is based largely on case reports. For this study, data were collected on clinical presentation and during long-term follow-up of 30 male patients with congenital nephrogenic diabetes insipidus. The majority of patients (87%) were diagnosed within the first 2.5 yr of life. Main symptoms at clinical presentation were vomiting and anorexia, failure to thrive, fever, and constipation. Three older patients were diagnosed as a result of events not directly related to the disease. Except for a possibly milder phenotype in patients with a G185C mutation, no clear relationship between clinical and genetic data could be found. Most patients were on hydrochlorothiazide-amiloride treatment without significant side effects. Two patients suffered from severe hydronephrosis with a small rupture of the urinary tract after a minor trauma, and two patients experienced episodes of acute urine retention. Height SD scores for age remained below the 50th percentile in the majority of patients, whereas weight for height SD scores showed a catch-up after several years of underweight.

Congenital Nephrogenic Diabetes Insipidus

Abstract Background Diabetes insipidus (DI) can be a common cause of polydipsia and polyuria. Here, we present a case of congenital nephrogenic diabetes insipidus (CNDI) accompanied with central diabetes insipidus (CDI) secondary to pituitary surgery. Case presentation A 24-year-old Chinese woman came to our hospital with the complaints of polydipsia and polyuria for 6 months. Six months ago, she was detected with pituitary apoplexy, and thereby getting pituitary surgery. However, the water deprivation test demonstrated no significant changes in urine volume and urine gravity in response to fluid depression or AVP administration. In addition, the genetic results confirmed a heterozygous mutation in arginine vasopressin receptor type 2 (AVPR2) genes. Conclusions She was considered with CNDI as well as acquired CDI secondary to pituitary surgery. She was given with hydrochlorothiazide (HCTZ) 25 mg twice a day as well as desmopressin (DDAVP, Minirin) 0.1 mg three times a day. There is no recurrence of polyuria or polydipsia observed for more than 6 months. It can be hard to consider AVPR2 mutation in female carriers, especially in those with subtle clinical presentation. Hence, direct detection of DNA sequencing with AVPR2 is a convenient and accurate method in CNDI diagnosis.

Congenital Nephrogenic Diabetes Insipidus

Abstract Background and Objectives: Congenital nephrogenic diabetes insipidus (NDI) is a rare genetic disorder characterized by renal inability to concentrate urine. Establishing the genetic diagnosis appears particularly important to NDI for early detection and differential diagnosis.Method: We utilized a Chinese multicenter registry to investigate genotype and phenotype in children with NDI from 2014 to 2019. The structural locations of the pathogenic mutations from this study and the literature, as well as population variants retried from gnomAD were analyzed. Results: A total of 10 boys from 9 families carried mutations in AVPR2 (8/10) or AQP2 (2/10). Another 7 relatives of the families were diagnosed by sequencing for partial or subclinical NDI. Patients presented with dehydration, polyuria-polydipsia, and severe hypernatremia with a median age at diagnosis of 1.0 month (IQR 0.16, 18). Protein structural analysis revealed a notable clustering of diagnostic mutations in the transmembrane regions of AVPR2, and enrichment of diagnostic mutations by autosomal dominant inheritance (AD) in the C terminal region of AQP2. The pathogenic mutations are significantly more likely to be buried inside the domain comparing the population variants. Through structural analysis and in silico prediction, the eight mutations identified in this study were considered as presumably disease causative. The most common treatments were thiazide diuretics and non-steroidal anti-inflammatory drugs (NSAIDs). Emergency treatment of hypernatremic dehydration in neonates should not choose the isotonic saline as a rehydration fluid.Conclusion: Genetic analysis presumably confirmed the diagnosis of NDI in every patient of the studied cohort. A plea of early identifying NDI confirmed by phenotype and genotype, and consequently optimize the treatment.
