Noninvasive Fibrosis Assessment in Chronic Viral Hepatitis C associated with End Stage Renal Disease.

INTRODUCTION

HCV is considered the most encountered viral infection that affect patients after hemodialysis sessions. Even though liver biopsy is considered the golden standard for hepatic diagnosis, additional methods have been used for assessing liver fibrosis. Transient elastography (TE) has evolved as a reference method in some European countries and allows the physician to carry out a fibrosis evaluation in a noninvasive, low-cost and rapid method. Our objective was to assess the efficacy of TE in staging patients with HCV liver disease associated with ESRD, thus choosing the correct moment to perform the procedure.

MATERIALS AND

METHODS

We included 34 patients known with ESRD within the regional Nephrology Clinic of Olt County Hospital and also having positive hepatitis C viral liver marker. TE was performed before and hemodialysis and data was analyzed.

RESULTS

The patients where we have encountered significant changes were especially within the F0 and F1 stage with a decrease of fibrosis after hemodialysis. Thus, 7 patients which had no fibrosis (F0) went from 4,14±0,98kPa to 3,54±0,84 (p<0,05) and 12 patients from the F1 stage went from 6,22±0,39kPa to 5,47±0,58kPa. The other stages had no significant changes with F2 changing after hemodialysis from 8.03±0,62kPa to 7, 76±0,6kPa.

CONCLUSIONS

TE represents a valuable tool for stiffness assessment and should be taken into considerations as a major option for ESRD patients with liver disease. However, more patients should be enrolled to strengthen this theory and thus providing more reliable results.
