NON-ADHERENCE TO HEPATITIS C TREATMENT: A BRAZILIAN REPORT

Não aderência ao tratamento para hepatite C: um estudo brasileiro

ABSTRACT

BACKGROUND:

In Brazil, since 2015, the treatment of hepatitis C is provided by SUS (Public Health System) with direct-acting antiviral (DAA).

OBJECTIVE:

To describe the rate of non-adherence patients to hepatitis C treatment by DAA, investigating the epidemiological data in a large database from Curitiba, Brazil.

METHODS:

Retrospective study with patients treated between January 2015 and June 2019. Patients were considered adherent when received all medication doses during their treatment. The following data were evaluated: gender, age, type of treatment, period of treatment, presence of diabetes or HIV, previous therapy, originated from SUS or private medicine, fibrosis grade and HCV genotype.

RESULTS:

1248 patients (56.8% males) were studied and 102/1248 (8.2%) were non-adherent to treatment. Age or gender not influenced significantly; 10.2% patients from SUS and 3.7% individuals from private medicine were non-adherent (P<0.0001; OR=2.9; CI95%=1.6-9.1); 13.1% patients were co-infected with HIV and among them, 15.9% abandoned treatment. Individuals without co-infection presented 7.0% of non-adherence (P<0.0001; OR=2.5; CI=1.5-4.1). All the other variables showed no differences in the adhesion rate.

CONCLUSION:

Our study showed that 8.2% of patients were non-adherent to HCV treatment, and that patients from the Public Health System and co-infected with HIV were significantly less adherent.
