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.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...
