Inflammatory patterns in plasma associate with hepatocellular carcinoma development in cured hepatitis C cirrhotic patients.

ABSTRACT:

Introduction

The risk of hepatocellular carcinoma persists in some patients despite achieving sustained virologic response with current interferon-free direct-acting antiviral therapy for hepatitis C. The subject of an even higher carcinoma risk in this context has been reported and is currently being debated. The quest for understanding this paradox relative to the dynamics of inflammatory biomarkers in cirrhosis patients receiving antiviral therapy thus remains a subject of importance.

Objective

Here, we aimed at evaluating the effects of direct-acting antiviral therapy-induced hepatitis C cure on plasmatic markers of systemic inflammation measured before, during and after treatment. Specifically, soluble immune mediator phenotype associations that impact the odds of hepatocellular carcinoma development and the related changes that arise upon direct-acting antiviral-mediated hepatitis C clearance in cirrhosis patients was investigated.

Methods

Employing multiplex technology that measured up to 91 circulating biomarker proteins, we profiled the plasma soluble immune mediator concentrations of cirrhosis patients who developed posttreatment hepatocellular carcinoma and their respective negative controls, before and after direct-acting antiviral treatment.

Results

Elevated pretherapy concentrations of specific soluble immune mediators including MCP-3, GDNF, CDCP1, IL-17C, IL-17A, signalling lymphocytic activation family 1, CCL11, FGF-5, LIF-R, interleukin 10 (IL-10), IL-10RA, IL-15RA, beta NGF, CCL28, CCL25 and NT-3 distinguished patients who developed posttreatment hepatocellular carcinoma relative to those that did not. Particularly, GDNF, FGF-5 and IL-15RA displayed independent predictive biomarker attributes for delineating carcinoma emergence regardless of de novo or recurrence groupings. Upon successful therapy, the elevated pretherapy soluble immune mediator establishment of the patients who eventually developed hepatocellular carcinoma stayed largely unperturbed whereas a panel of some 38 soluble immune mediators in the posttherapy carcinoma-free patients experienced significant ameliorations.

Conclusions

These results have considerable implications for delineating potential hepatocellular carcinoma emergence before initiating direct-acting antiviral therapy for hepatitis C in cirrhosis patients. They provide preliminary contribution to unravelling cases where the benefit of direct-acting antiviral therapies would be superior to the risk of developing carcinoma.
