Growth hormone treatment associates with improved circulating anti-aging protein Klotho and reduced arterial stiffness in children with CKD.

ABSTRACT:

Background

Chronic kidney disease (CKD) is characterized by low levels of the anti-aging protein α-Klotho and accelerated cardiovascular (CV) morbidity. Short-term treatment with growth hormone (GH) was shown to enhance soluble Klotho (sKlotho), the circulating form of α-Klotho, and endothelial function in patients with CKD. We hypothesized that long-term GH treatment in pediatric patients with CKD improves sKlotho levels and CV morbidity.

Methods

We performed a case-cohort study within the Cardiovascular Comorbidity in Children with Chronic Kidney Disease (4C) study including 101 children with CKD stages 3-5 treated with and without GH. Patients were assessed for serum sKlotho, intact fibroblast growth factor 23 (iFGF23), somatomedin insulin-like growth factor 1 (IGF1), pul
