Low-birth-weight individuals have a higher risk of hypertension and end-stage renal disease (ESRD). Here we investigated whether low birth weight was associated with earlier onset of ESRD in patients with autosomal dominant polycystic kidney disease (ADPKD). In collaboration with all Danish departments of nephrology, 307 of 357 patients with ADPKD and ESRD born and living in Denmark were recruited. We were able to analyze complete data of 284 patients obtained from both hospital medical files and midwife protocols in the Danish State Archives. Multivariable linear regression adjusted for birth weight, adult height, mean arterial pressure, gender, birth decade, and type of antihypertensive treatment showed that for every kilogram increase in birth weight, the age at onset of ESRD significantly increased by 1.7 years. Male gender and increased mean arterial pressure were both associated with earlier onset of ESRD. Patients treated with renin-angiotensin system blockade or calcium channel blockers during follow-up had significantly later onset of ESRD by 4.3 years and 2.1 years, respectively. Treatment with beta-blockade or a diuretic was not associated with the age at onset of ESRD. Thus, low birth weight may contribute to considerable phenotypic variability in the progression of renal disease between individuals with ADPKD.
