摘要

Background

Autosomal dominant polycystic kidney disease (ADPKD) demonstrates broad genetic and phenotypic variability, with kidney failure (KF) occurring across a wide age spectrum. Despite several predictor tools, there remains a need to identify factors associated with rapid disease progression. This study describes the phenotypic characteristics of a multicentric cohort experiencing early-onset KF by age 40.

Methods

This retrospective, multicenter cohort study analyzed longitudinal data of rapidly progressive ADPKD patients (n = 199). The prevalence of established risk factors was compared to nine existing ADPKD cohorts (ntotal = 6782) with KF after 40 years of age. We examined the longitudinal impact of early hypertension and urological events on the risk of developing KF.

Results

The median age at ADPKD diagnosis was 22.3 years (IQR, 16.5–28.6) and median age of KF was 35.6 years (31.7–38.0). Hypertension was observed in 68.1% of cases, with early-onset hypertension being more common among those with accelerated progression towards KF. Urological events were present in 60.1% of cases, with a high burden of gross hematuria (30.4%). Existing ADPKD cohorts had a mean age of 45.5 years, with weighted prevalences of hypertension (71.1%), kidney stones (22.4%), hematuria (22.9%), and urinary tract infections (22.8%). Extrarenal manifestations were less prevalent compared to other ADPKD cohorts.

Conclusion

This study outlines a cohort of ADPKD patients with accelerated disease progression, reaching KF before age 40. Hypertension and urological events were highly prevalent at a young age, emphasizing the importance of early and regular blood pressure monitoring.
