Introduction: Hepatitis C Virus (HCV) is the main culprit for liver diseases worldwide. In Manipur its incidence is increasing, mainly due to blood borne transmission through intravenous drugs users. Among the extrahepatic manifestations of HCV infection-arthropathy (joint pain, swelling and stiffness) is most common. Exact mechanism of arthropathy are not well elucidated but are probably connected with the participation of the immune system and due to the replicating virus in the affected tissues, organ systems.
Aim: To determine the articular manifestations in HCV infected patients and to study the association between articular manifestations and liver fibrosis.
Materials and Methods: This cross-sectional study enrolled 100 hepatitis C infected patients above 18 years of age who attended Medicine OPD, gastroenterology and liver clinic or admitted in the General Medicine wards, Regional institute of Medical Sciences (RIMS), Imphal, Manipur, India. Blood samples were collected for Complete Blood Count, Erythrocyte Sedimentation Rate, C Reactive Protein, Liver function test, Renal function test, HCV, Rheumatoid Factor (RF), Antinuclear Antibody (ANA), anti-ds DNA. Ultrasound (USG) whole abdomen and X-rays of involved joints were done when indicated. Markers for liver stiffness/fibrosis, {Aspartate Aminotransferases (AST) to Platelet Ratio Index (APRI)} score, The fibrosis-4 (FIB-4) score and AST/Alanine Transaminase (ALT) ratio were calculated and compared. The Statistical Package for Social Sciences(SPSS) (IBM) version 21.0 was used for statistical analysis. Chi-square and Fischer’s-exact test were used.
Results: A total of 100 hepatitis C infected patients were enrolled in the present study. Majority of the study subjects were males (63%) under 40 years of age (69%). Eighty-four (84%) patients were intravenous drug users. Joint pain, swelling and stiffness was present in 37 (37%), 31 (31%) and 24 (24%), respectively. Around 36 (36%), 45 (45%) and 29 (29%) of the participants had significant fibrosis with respect to FIB 4 score, APRI and USG finding, respectively.
Conclusion: The prevalence of joint pain was 37% in this study. Females and younger age group were more associated with articular manifestation. The present study concluded that patient with articular manifestation were seen to have significant fibrosis with respect to FIB 4 score, APRI and USG finding, AST/ALT.
