Insights
Direct-acting antiviral agents (DAAs) significantly improved sexual dysfunction in both men and women with hepatitis C virus (HCV) infection. This viral clearance led to enhanced sexual function in both sexes post-treatment.
Area of Science:
- Hepatology
- Virology
- Sexual Medicine
Background:
- Hepatitis C virus (HCV) infection can lead to sexual dysfunction (SD) in both males and females.
- The impact of direct-acting antiviral agents (DAAs) on SD in HCV patients requires further investigation.
Purpose of the Study:
- To assess the effect of HCV clearance achieved through DAAs on sexual dysfunction in male and female patients.
- To evaluate the efficacy of DAAs in restoring sexual function in individuals with chronic HCV.
Main Methods:
- A cohort of 100 sexually active men and 100 sexually active women with chronic HCV, eligible for DAAs, were enrolled.
- Male participants completed the International Index of Erectile Function (IIEF-5), and female participants completed the Female Sexual Function Index (FSFI).
- Assessments were conducted before, during, and 3 months after DAA treatment for HCV.
Main Results:
- HCV treatment with DAAs led to a statistically significant improvement in erectile function scores (IIEF-5) in men (p < .01).
- Female participants showed a significant increase in overall sexual function scores (FSFI) post-treatment (p < .01).
- No significant difference was observed in the degree of sexual function improvement between males and females at any assessment point (p > .05).
Conclusions:
- HCV clearance using DAAs is associated with significant improvements in sexual dysfunction in both men and women.
- DAA therapy represents an effective strategy for addressing sexual dysfunction in patients with chronic hepatitis C.
- The study highlights the positive impact of viral eradication on overall quality of life, including sexual health, in HCV patients.
Objective:
The impact on male and female sexual dysfunction of treating hepatitis C virus (HCV) using direct-acting antiviral agents (DAAs) has not been sufficiently studied. The aim of this study was to assess the impact of HCV clearance with DAAs on sexual dysfunction (SD) in both sexes.
Methods:
In chronic HCV patients who were eligible for DAAs, 100 sexually active men completed the Arabic version of the international index of erectile function questionnaire (IIEF-5), and the same number of sexually active women completed Female Sexual Function Index (FSFI), before, at the end of, and 3 months after, treatment for HCV.
Result:
The mean of the IIEF-5 scores for male patients was 16.29 ±.07 before treatment, 16.88 ± 3.63 3 months after treatment (p < .01), and was significantly higher, at 19.06 ± 3.31 6 months after treatment cessation (p < .01). In female patients, the mean total FSFI score at baseline was 19.22 ± 2.40 and after 3 months of treatment was 21.61 ± 3.45 (p < .01), with a significant increase (25.09 ± 4.52) after 6 months (p < .01). No difference in the improvement of sexual function was reported either after 3 months or at the end of treatment between males and females (p > .05).
Conclusions:
Significant improvement in SD associated with HCV infection in both sexes was recorded following viral clearance using DAAs treatment.
