Uso de boceprevir y telaprevir en pacientes con VHC (aspectos prácticos)

Barriers to HCV treatment in the era of triple therapy: a prospective multi-centred study in clinical practice

BACKGROUND & AIMS

(i) To describe the demographic, clinical, virological and histological characteristics of the patients undergoing evaluation for indication of triple therapy against hepatitis C virus genotype 1, and to identify the reasons why candidate patients are excluded; and (ii) to evaluate the characteristics of the healthcare environment related to treatment.

METHODS

Observational, prospective and multi-centred study involving 16 hospitals of Spain. Data were collected on 1122 patients receiving attention in the outpatient clinics between June and December 2012.

RESULTS

Of the 1122 patients evaluated, 769 were finally included in this study; 27% (211/769) had contraindications to the therapy. Of those without contraindications, 54% (301/558) did not receive the treatment, and so, only about a third of the patients (33%-257/769) underwent therapy. The reasons for not initiating therapy were as follows: patient refusal (30%), mild disease/awaiting new treatments (34%), restrictions by the health service (30%), other reasons (6%). In univariate analyses, the probability of receiving treatment was related to: age <60 years, male gender, high education level, advanced fibrosis, having had previous treatment, being assessed in a centre of excellence. In multivariate analyses, the factors independently related to the probability of receiving treatment were as follows: high education level of the patients (P = 0.004), advanced fibrosis (P < 0.001) and centres of excellence (P = 0.009).

CONCLUSION

Despite the high efficacy of triple therapy, only a small proportion of patients receive the treatment. The causes related to non-treatment depend on patient factors, disease stage and characteristics of the health-service provision.

[Telaprevir in treatment-naïve patients with HCV monoinfection]

Chronic hepatitis due to the hepatitis C virus (HCV) infection affects nearly 180 million people worldwide. This infection is curable. Until 1 year ago, the only treatment for genotype 1 HCV was the combination of pegylated interferon and ribavirin, which was only moderately effective (40-50%). The introduction of new antiviral agents, such as telaprevir, represents a change of paradigm and has revolutionized the treatment of this infection. This drug has increased the likelihood of viral response (to 80%) and has allowed treatment length to be shortened in more than 50% of patients. New stopping rules have been developed to avoid the development of resistances. Finally, special attention should be paid to potentially serious adverse effects, particularly anemia and cutaneous alterations.
