Serum Adiponectin, Vitamin D, and Alpha-Fetoprotein in Children with Chronic Hepatitis C: Can They Predict Treatment Response?

Abstract EN

Background & Aims.

The currently available treatment for chronic hepatitis C (CHC) in children is costly and with much toxicity.

So, predicting the likelihood of response before starting therapy is important.

Methods.

Serum adiponectin, vitamin D, and alpha-fetoprotein (AFP) were measured before starting pegylated-interferon/ribavirin therapy for 50 children with CHC.

Another 21 healthy children were recruited as controls.

Results.

Serum adiponectin, vitamin D, and AFP were higher in the CHC group than healthy controls (p<0.0001, p=0.071, and p=0.87, resp.).

In univariate analysis, serum adiponectin was significantly higher in responders than nonresponders (p<0.0001) and at a cutoff value ≥8.04 ng/mL it can predict treatment response by 77.8% sensitivity and 92.9% specificity, while both AFP and viremia were significantly lower in responders than nonresponders, p<0.0001 and p=0.0003, respectively, and at cutoff values ≤3.265 ng/mL and ≤235,384 IU/mL, respectively, they can predict treatment response with a sensitivity of 83.3% for both and specificity of 85.7% and 78.6%, respectively.

In multivariate analysis, adiponectin was found to be the only independent predictor of treatment response (p=0.044).

Conclusions.

The pretreatment serum level of adiponectin can predict the likelihood of treatment response, thus avoiding toxicities for those unlikely to respond to therapy.
