Summary

The prevalence of hepatitis C virus infection (HCV) in patients with inflammatory bowel disease (IBD) ranges from 1-6%. Direct-acting antivirals (DAAs), with cure rates \>90%, represent a radical change from interferon-based therapies. The ECCO (European Crohn's and Colitis Organisation) guidelines (Kucharzik T, Ellul P, Greuter T, et al. ECCO Guidelines on the Prevention, Diagnosis, and Management of Infections in Inflammatory Bowel Disease. J Crohn's Colitis. 2021;15(6):879-913) warns about the risk of IBD reactivation due to the effect of DAAs, but HCV management in this situation is uncertain given the lack of evidence.

The project is proposed as the largest retrospective multicenter descriptive study carried out to evaluate the use of DAAs for HCV eradication in patients with IBD. The Eneida database (Zabana Y, Panés J, Nos P, et al. The ENEIDA registry (Nationwide study on genetic and environmental determinants of inflammatory bowel disease) by GETECCU: Design, monitoring, and functions. Gastroenterol y Hepatol. 2020;43(9):551-8.) of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) is an adequate registry to identify patients with HCV infection. The serological status of the infection is frequently recorded in the ENEIDA database, and it is generally evaluated at the time of IBD diagnosis, before starting immunosuppressive treatment. The ENEIDA registry has the advantage over large population studies that researchers have access to relevant details of the clinical history, which can respond to the controversies raised.

This multicenter retrospective descriptive study will provide useful information to be able to give evidence-based recommendations regarding treatment of HCV in patients with IBD.

Conditions

  • Inflammatory Bowel Diseases
  • Hepatitis C Virus Infection

Interventions

DRUG

Assess the effectiveness and safety of DAAs in patients with IBD.

Variables evaluated: age, gender, location, extent, phenotype, and activity of IBD, treatments, anti-HCV and viral load, DAA treatment and duration, fibrosis and hepatic decompensation and adverse effects (AE).

DRUG

Evaluate the interaction of DAAs with IBD drugs, particularly immunosuppressants and/or biologics.

Variables evaluated: Interactions.

OTHER

Assessment of the impact of DAAs on the course of IBD.

Qualitative variables will be expressed as a percentage and 95% confidence interval and quantitative variables as median and interquartile range. A priori it is difficult to determine which statistical analysis should be performed. It is basically a descriptive study, and the subsequent statistical analysis will depend on the evolution that the patients have presented in relation to the DAA treatment. If the drugs have been well tolerated without adverse effects, further statistical analysis will not be necessary. Instead, if the DAAs trigger activity outbreaks, variables related to the appearance of these outbreaks will be evaluated (type of DAA, immunomodulator, ...). To compare whether there are differences between the established groups, Chi Square (in qualitative independent variables), a t-student or ANOVA or their corresponding non-parametric tests (in quantitative independent variables) will be used. Statistical significance has been set at a probability level of \<0.05.
