Congenital Nephrogenic Diabetes Insipidus (NDI) is a rare genetic disorder that causes massive polyuria. To better understand NDI in children, we present, to our knowledge, the largest retrospective case series to date. Our objective for this study was to describe clinical presentation, genetic etiology, treatment and outcomes in patients < 21 years with NDI.


Midwest Pediatric Nephrology Consortium centers (MWPNC) conducted a retrospective chart review.


We report 50 subjects from 12 centers. Median age at diagnosis was 125 days (interquartile range (IQR), 37, 296) with 86% male. 66% were white, 14% black, 8% Asian and 12% other race. 18% had a water deprivation test and 50% had a DDAVP loading test (median age at DDAVP 155 days (IQR, 101, 392)). At diagnosis, 74% had an elevated serum osmolality (> 300 MOsm/L). 54% had genetic testing with mutations in AVPR2 (65%), AQP2 (14%), and unavailable (21%). 28% had a diagnosis of CKD; 55% Stage 1, 36% Stage 2 and 9% Stage 5. Median age at time of CKD diagnosis was 4.1 years (IQR, 3.1, 9.4). 18% had abnormal renal ultrasound findings; the majority were hydronephrosis and pelvicaliectasis. Table 1 lists pharmacologic interventions. Other medications included chlorothiazide (2%), chlorthiadone (4%), other NSAIDS (8%) and spironolactone (6%). Figure 1 lists nutritional management. At last follow-up, 52% reported to have enuresis.


Our results suggest a multi-centered approach to this rare disease yields robust information that can inform future novel treatment studies and creation of a clinical consensus for management of children with NDI.
