[Oral galactose loading in characterizing the elimination and metabolizing performance of the liver in chronic renal
Insights
The galactose load test revealed impaired liver function in children with chronic renal insufficiency undergoing dialysis. Kidney transplant recipients on azathioprine also showed disturbed galactose metabolism, unlike those on cyclosporine-A.
Area of Science:
- Nephrology
- Hepatology
- Pediatrics
Context:
- Chronic renal insufficiency (CRI) affects liver function.
- Assessing liver performance is crucial in pediatric kidney disease management.
- Galactose metabolism serves as a marker for liver health.
Purpose:
- To characterize liver elimination and metabolization performance in children with CRI.
- To evaluate the impact of conservative treatment, chronic hemodialysis, and kidney transplantation on liver function.
- To investigate the effects of immunosuppressive therapies (azathioprine, cyclosporine-A) on galactose metabolism post-transplant.
Summary:
- The galactose load test was performed on children with healthy kidneys/livers, CRI (conservatively treated or on hemodialysis), and post-kidney transplant.
- Children on chronic hemodialysis exhibited elevated blood galactose levels, suggesting impaired liver function possibly due to uremic intoxication.
- Kidney transplant recipients on azathioprine showed disturbed galactose utilization, while those on cyclosporine-A had normal levels.
Impact:
- This study highlights potential liver dysfunction in pediatric patients with chronic renal insufficiency and post-kidney transplantation.
- Findings suggest that hemodialysis and azathioprine therapy may negatively impact liver metabolic capacity.
- Results indicate that cyclosporine-A may not adversely affect galactose metabolism in pediatric kidney transplant recipients.
Abstract:
For characterising the elimination and metabolisation performance of the liver in chronic renal insufficiency the galactose load test was carried out. 9 children with healthy liver and kidneys, 35 children with chronic renal insufficiency (15 were conservatively treated = group 1, 20 were in the chronic haemodialysis programme = group 2) as well as 5 children after kidney transplantation were examined. In group 1 a normal blood galactose concentration was present. Patients of the 2nd group showed increased concentrations of galactose in the blood which might refer to a decreased redox potential in the liver caused by the uraemic intoxication. In the group of patients who underwent a kidney transplantation in the patients with azathioprine therapy a disturbed use of galactose was present. Children with cyclosporin-A had a normal galactose concentration.
