CURING HEPATITIS C WITH THE NEW DIRECT ACTING ANTIVIRALS DID NOT IMPROVE INSULIN RESISTANCE AFTER ONE YEAR.

Abstract

BACKGROUND:

Chronic hepatitis C still figures as an important cause of morbidity among the Brazilian population, and is closely associated with metabolic disturbances, including insulin resistance (IR), which can be evaluated by the Homeostatic Model Assessment (HOMA-IR). IR may entail lower sustained virologic response (SVR) on certain therapeutic regimens and faster progression to advanced hepatic fibrosis. With the arrival of the direct acting agents (DAA) in hepatitis C treatment, there is an increased need in observing the impact in patients' IR profile while using such therapies.

OBJECTIVE:

- 1) To compare the results of HOMA-IR in patients affected by chronic hepatitis C before treatment with DAA and 12 months after finishing it with SVR. 2) To evaluate the evolution of weight after curing chronic hepatitis C.

METHODS:

We included patients older than 18 from two tertiary care in Curitiba - PR, of both sexes, with chronic hepatitis C, treated with DAA, from July 2015 to September 2017. We also evaluated the patients' levels of fasting insulin, fasting glucose and glycated hemoglobin before starting treatment and 12 months after finishing it. We also used epidemiologic data, such as age, sex, hepatic fibrosis degree, body mass index, abdominal circumference, viral genotype and the presence of diabetes mellitus before and after treatment. IR was assessed before and after treatment and calculated by the HOMA-IR score. Insulin resistance was defined by a HOMA-IR greater than 2.5. We excluded patients who lost follow-up, those who did not achieve SRV and those who did not have a laboratory profile. The results of quantitative variables were described by means, medians, and standard deviations. P values <0.05 indicated statistical significance.

RESULTS:

We included 75 patients in this study, with a mean age of 55.2 years and 60% of males. Forty-three patients had advanced fibrosis. Twenty one (28%) had a previous diabetes mellitus diagnosis. We identified 31 (41.3%) patients with IR before antiviral treatment, and this number increased to 39 (52%) after 12 months of finishing treatment, according to HOMA-IR. There was no statistic difference between insulin, glucose and HOMA-IR measurements before and after curing hepatitis C. We observed a weight gain in patients shortly after curing hepatitis C, but this did not persist at the end of the study. We also had no significant difference in IR prevalence when viral genotype was concerned.

CONCLUSION:

In this study, there was no statistically significant difference between HOMA-IR results in patients before and 12 months after treatment for hepatitis C. Even though patients gained weight after the cure, this was not statistically significant after a year (P=0.131).
