Arterial stiffness and choroidal vascularity index in autosomal dominant polycystic kidney disease with preserved
Insights
Autosomal dominant polycystic kidney disease (ADPKD) is linked to increased arterial stiffness and choroidal vascular changes, even in early stages. These findings suggest widespread vascular issues in ADPKD patients with preserved kidney function.
Area of Science:
- Vascular Biology
- Nephrology
- Ophthalmology
Background:
- Autosomal dominant polycystic kidney disease (ADPKD) is a systemic disorder with early vascular effects.
- Subclinical vascular changes, including arterial stiffness and ocular microvascular alterations, may precede kidney function decline in ADPKD.
- Limited data exist on the relationship between systemic arterial stiffness and choroidal microvasculature in early ADPKD.
Purpose of the Study:
- To investigate the association between systemic arterial stiffness and choroidal microvascular structure in patients with early-stage ADPKD.
- To compare arterial stiffness and choroidal parameters between ADPKD patients and healthy controls.
- To identify determinants of arterial stiffness and choroidal vascularity in ADPKD.
Main Methods:
- Cross-sectional study including 41 ADPKD patients with preserved kidney function and 40 controls.
- Arterial stiffness assessed by cardio-ankle vascular index (CAVI).
- Choroidal microvasculature measured by spectral-domain optical coherence tomography, including choroidal vascularity index (CVI).
Main Results:
- ADPKD patients showed significantly higher CAVI and CVI compared to controls.
- No significant correlation was found between CAVI and CVI.
- ADPKD status was independently associated with higher CAVI and CVI.
Conclusions:
- Early-stage ADPKD is characterized by increased systemic arterial stiffness and choroidal microvascular remodeling.
- Elevated CAVI and CVI indicate early, multi-level vascular involvement in ADPKD.
- Combined assessment of systemic and ocular vascular parameters may offer insights into subclinical vascular changes in ADPKD.
Background:
Autosomal dominant polycystic kidney disease (ADPKD) is increasingly recognized as a systemic disorder with early vascular involvement, even before significant kidney function decline. Arterial stiffness and ocular microvascular alterations may reflect subclinical vascular changes in this population. However, data regarding the relationship between systemic arterial stiffness and choroidal microvascular structure in early ADPKD are limited.
Materials And Methods:
A total of 41 patients with ADPKD and 40 controls were included. In this single-center, cross-sectional study, patients with ADPKD and preserved kidney function (estimated glomerular filtration rate > 60 mL/min/1.73m2) and age- and sex-matched healthy controls were evaluated. Arterial stiffness was assessed using the cardio-ankle vascular index (CAVI). Ocular structural and microvascular parameters were measured using spectral-domain optical coherence tomography, including the choroidal vascularity index (CVI). Group comparisons, correlation analyses, and multivariable linear regression models were performed to identify independent determinants of CAVI and CVI.
Results:
CAVI was significantly higher in the ADPKD group compared with controls (p < 0.01). CVI was also significantly increased in patients with ADPKD, whereas subfoveal choroidal thickness did not differ between groups. No significant correlation was observed between CAVI and CVI. In multivariable analyses, ADPKD status remained independently associated with both higher CAVI and higher CVI after adjustment for relevant covariates.
Conclusion:
Patients with early-stage ADPKD exhibit increased systemic arterial stiffness and choroidal microvascular remodeling despite preserved kidney function. The coexistence of elevated CAVI and CVI suggests early, multi-level vascular involvement in ADPKD. Combined assessment of systemic and ocular vascular parameters may provide complementary insights into subclinical vascular alterations in this patient population.
