Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant

In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...

Background:

Traditional kidney explant cultures at air-liquid interfaces hinder 3D structure and developmental data interpretation.
Existing methods do not fully replicate the in vivo microenvironment for kidney development.

Purpose of the Study:

To develop and validate a 3D hydrogel embedding technique for real-time kidney morphogenesis.
To investigate the impact of hydrogel material properties (stiffness and adhesion) on kidney development.

Main Methods:

Utilized acrylated hyaluronic acid hydrogels for 3D kidney explant culture, allowing independent tuning of stiffness and adhesion.
Captured real-time kidney morphogenesis, tubule dynamics, and branching defects.
Analyzed the effects of varying hydrogel properties on nephron formation and kidney shape.

Main Results:

3D hydrogel culture better approximates in vivo niche spacing and tubule dynamics.
Sufficient hydrogel stiffness and adhesive ligands are crucial for maintaining kidney shape.
Increased hydrogel adhesion enhanced nephron formation per ureteric bud tip.
Matrix stiffness exhibited a "Goldilocks effect", with optimal development around 2 kPa.

Conclusions:

The 3D hydrogel embedding technique provides in vivo-like kidney morphogenesis, enhancing insights into congenital kidney diseases.
Understanding the mechanical boundary conditions is vital for fundamental kidney development research and renal engineering applications.
