Abstract

GARCIA, João Batista Santos et al. Clinical evaluation and prevalence of fibromyalgia in hepatitis C patients. BrJP [online]. 2019, vol.2, n.4, pp.308-315.  Epub Dec 02, 2019. ISSN 2595-3192.  http://dx.doi.org/10.5935/2595-0118.20190057.

BACKGROUND AND OBJECTIVES:

The worldwide distribution and etiology of fibromyalgia are poorly understood. It is believed that different factors are involved, such as hepatitis C virus infection. The aim of this study was to estimate the prevalence of fibromyalgia in hepatitis C virus infected patients, trying to identify the occurrence of liver injury, extrahepatic clinical manifestations, anxiety, depression, and the impact on the quality of life.

METHODS:

This is a cross-sectional study of patients (n=118) with hepatitis C virus infection who were compared with a group of clinically stable patients not infected with the hepatitis C virus (n=118). The Anxiety and Depression Questionnaire was applied, and for those diagnosed with fibromyalgia, the Fibromyalgia Impact Questionnaire. Liver biopsies were analyzed according to the METAVIR classification. The Schirmer test was performed to investigate abnormal tear production in the studied patients. Data analysis was performed using the Statistical Package for Social Sciences (SPSS) software, v.10.0.

RESULTS:

The prevalence of fibromyalgia in infected patients was 7.6%. In patients infected with fibromyalgia, a significant prevalence of anxiety and depression was observed. Fibromyalgia Impact Questionnaire scores were higher in infected patients with fibromyalgia. When comparing the complementary tests in infected patients with and without fibromyalgia, no significant differences were found for the Schirmer test, viral genotype, and degree of fibrosis and liver inflammation.

CONCLUSION:

In females, there was a positive relationship between hepatitis C virus infection, fibromyalgia, and extrahepatic symptoms, which translates into a higher prevalence of anxiety and depression and impaired quality of life.
