RESUMO
Sustained virologic response (SVR) after direct-acting antiviral (DAA) therapy for chronic hepatitis C results in significant decreases in liver stiffness measured by transient elastography (TE). The aim of this study was to clarify if TE can guide post-SVR management in patients with advanced fibrosis or cirrhosis prior to treatment as current guidelines are unclear on the role of TE after SVR. In total, 84 patients with hepatitis C virus and advanced fibrosis or cirrhosis and from a single center underwent DAA treatment and achieved SVR. Overall, 62% had improved liver stiffness that was consistent with regression of at least one stage of fibrosis. In the cirrhosis group, 48% showed fibrosis regression by at least two stages by TE (<9.5 kPa). In the F3 fibrosis group, 39% regressed by at least two stages (<7 kPa). The median time from SVR to regression by TE was 1 year. Fifteen patients with liver biopsies prior to SVR underwent a biopsy after SVR; 13 of these patients had improved liver stiffness (to <9.5 kPa). The post-SVR liver biopsies of only 4 patients showed F1-F2 while 11 patients showed F3-F4; however, morphometry of the first 11 biopsied patients revealed that 10 patients had an average 46% decrease in collagen content. Conclusion: This is the first DAA study that also has paired liver biopsies showing fibrosis regression. After SVR is achieved, improvements in liver stiffness measured by TE are seen in a majority of patients with advanced fibrosis/cirrhosis within 2 years. TE improvements are overstated when compared to histologic staging but confirmed with morphometric analysis. It is unclear whether TE following SVR can reliably predict when patients no longer require advanced fibrosis/cirrhosis monitoring after SVR.
RESUMO
We present a nulliparous woman with mild to moderate ulcerative colitis (UC) and multiple failed cycles of in vitro fertilization (IVF) in whom we achieved a successful, viable pregnancy following clinical and endoscopic UC remission. Infertile patients with inflammatory bowel disease who have failed multiple cycles of IVF should try to achieve clinical remission and mucosal healing (absence of erosions or ulcers) prior to reattempting conception. Furthermore, deficiencies in vitamin B12, vitamin D, and iron should be addressed.
