Background: Rheumatoid arthritis (RA) is an immune-mediated, polyarthritis linked with various genetic and environmental causative agents. Among environmental triggers, Epstein-Barr Virus (EBV) is considered the most potent etiological agent.
Objective: This study aimed to investigate the prevalence of EBV and its genotypes in RA patients and to investigate their association with clinical and laboratory parameters of RA.
Methodology: This study included blood samples of RA and control healthy individuals (100 each). Blood samples along with clinical and laboratory parameters were collected from patients after consent in the Department of Rheumatology, at Lady Reading Hospital, in Peshawar Pakistan. Blood samples were processed for DNA extraction followed by PCR amplification for EBV detection and genotype discrimination.
Results: RA patients were 85 females and 15 males with a mean age of 40.13±14.05 years. EBV Type-1 was detected in 45% of RA and 9% of control cases. The mean disease duration of RA patients was 6.61±6.23 years. Out of 100 diseased patients, 43% were seropositive rheumatoid arthritis (SPRA) and showed a significant correlation with a family history of RA in EBV-positive individuals (P = 0.017). The demographic, clinical, and laboratory parameters of RA patients showed a non-significant association with EBV. Moreover, only a family history and Serum creatinine of RA patients showed a significant association with EBV (P = 0.0001 and P = 0.022 respectively).
Conclusion: It is concluded that EBV-1 is prevalent and associated with RA. Further investigation is required for detailed genetic analysis of EBV to determine its possible role in modulating the immune system in RA.
