BACKGROUND: Behçet's syndrome (BS) is one of the multisystemic diseases that presents with oral ulceration and several other systemic manifestations including genital ulceration, folliculitis, erythema nodosum-like lesions, uveitis, and arthropathy. Ocular manifestation, central nervous system involvement, and gastrointestinal manifestation account for most of the complications of this disease, whereas orogenital ulceration and dermatological involvement affects the quality of life. The cause of the disease is not fully elucidated; however, herpesviruses have long been thought to play a pivotal role in the disease pathogenesis. OBJECTIVE: To investigate the seroprevalence and salivary shedding of herpesviruses in BS. METHOD: The levels of specific immunoglobulin G in six different herpesviruses in serum samples collected from 54 BS, 28 healthy controls (HC), and 7 recurrent aphthous stomatitis (RAS) patients were investigated. Salivary viral load was also quantified for these viruses in matched saliva samples using quantitative real-time polymerase chain reaction. RESULTS: The BS had lower cytomegalovirus (CMV) IgG level in comparison to HC (p=0.0226) and RAS (p=0.0450). There was statistically significant higher salivary shedding of Epstein-Barr virus (EBV) in BS in comparison to HC (p=0.0052), but not RAS (p=0.3318). CONCLUSIONS: A high EBV shedding was observed in both BS and RAS and a lower level of CMV IgG was observed in BS only. The reason for the observed lower level of CMV IgG in BS is not clear. However, one explanation might be a defect in the cross-talk between innate and adaptive immune responses which was suggested by a previously described defect in the toll-like receptor 1 and 2 heterodimer formation and function, this being the initial receptor sensing of CMV.
