Abstract:
Background

Infectious agents are considered as one of the possible etiological factors of systemic lupus erythematosus (SLE). It has been suggested that torque teno virus (TTV) may trigger autoimmune disorders, but few studies have been conducted on the relationship between this virus and autoimmune diseases, especially SLE. The present study aimed to evaluate the association between TTV frequency and SLE.

Materials & Methods

Serum samples were collected from a total of 116 participants, including 58 healthy people and 58 SLE patients who referred to the rheumatology clinic of Shahid-Beheshti hospital in Kashan, Iran from January 2020 to January 2021. After the extraction of viral DNA from the samples, a nested PCR test was performed using specific primers to detect TTV.

Findings

TTV was detected in 43 SLE patients (74.1%, 95% CI: 63.4-86.2) and 33 healthy individuals (56.9%, 95% CI: 44.1-69.0). A significant correlation was found between SLE and the presence of TTV (r= .32, p= .03). There was no correlation between the presence of TTV and musculoskeletal involvements, skin lesions, renal manifestations, and hematological manifestations (r< .05, p> .05). TTV was detected more frequently in patients with active lupus than in patients with quiescent disease, and this difference was significant (p= .048).

Conclusion

A significant association between TTV and SLE was observed in the present study; however, further studies are needed to investigate the role of TTV in the pathogenesis and clinical course of SLE.
