Abstract
Behçet's disease (BD) is a multisystemic chronic vasculitis. Sustained and enhanced immune responses were reportedly associated with active BD. Although genetic polymorphisms increase development risk, genetic factors alone cannot account for BD development, suggesting the involvement of exogenous factors. Also, how various infectious agents promote BD in high-risk populations is not fully understood. In this review, we summarized the current findings on the associations of infectious agents with BD pathogenesis. The review also highlights the potential microbial risk factors and their pathogenic role in BD progression. Interactions between genetic and infectious risk factors was also discussed. Furthermore, evidence implied that after the eradication of infectious agents, BD symptoms and recurrence decreased, thus highlighting that combined use of antibiotics may be an effective therapy for BD. Finally, we summarized the main limitation of the current related studies, providing valuable insights and a basis for future studies on BD pathogenic factors.

Characterization of Occult Hepatitis B Virus Infection Among Iranian Patients with Behcet's Disease; Correlation with Clinical Status. HEPATITIS MONTHLY 2021; 21. [DOI: 10.5812/hepatmon.105078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Revised: 02/13/2021] [Accepted: 02/13/2021] [Indexed: 08/30/2023]
Abstract
Background: Behcet's disease (BD) is a chronic multisystem vasculitis with an unknown etiology. During the past years, several reports are published on the occult hepatitis B infection (OBI), the presence of hepatitis B virus (HBV) DNA in the absence of HBsAg, in rheumatic diseases. Objectives: The current study aimed to, firstly, investigate the prevalence of OBI in patients with BD, and, secondly, its potential association with the clinical and therapeutic status of BD. Methods: HBV serological markers and HBV DNA were evaluated in 220 consecutive BD patients to detect OBI. Demographic and clinical data of OBI positive and negative groups were compared. Results: The mean age of patients was 39.24 (± 10.57), and 134 (62.9%) were male. The mean disease duration was 14.13 (± 8.63) years. No HBsAg positive case was found, but HBV DNA was found in 19 (8.6%) patients. The median viral load value was 475.84 copy/mL. We compared clinical data of 10 OBI positive and 156 OBI negative BD patients with complete and accessible data. There was no difference between the two groups concerning demographic characteristics (age, sex, and disease duration), different clinical manifestations, or types of medications (immunomodulatory, cytotoxic, and corticosteroids). Conclusions: This is the first study showing a rather high prevalence of OBI among BD patients. We did not find any correlation between OBI positivity and different clinical manifestations, medications, or HLA-B51. Further studies are needed on a larger group of patients and by molecular HBV evaluation (as well as serologic) regarding this possible association.

Abstract
Abstract
Background: Behcet’s disease (BD) is a chronic, inflammatory multisystemic condition of unknown etiology. Although the cause of BD is not clear, it is believed to be the result of an autoimmune process triggered by an infectious or environmental agent (possibly local to a geographic region) in a genetically predisposed individual.
Objective: To detail current knowledge of the role of microorganisms in the pathogenesis of BD and review the infectious etiology of this disease.
Methods: The review based on publication in SCOPUS, Science direct, and PubMed.
Results: A microbial infection has been implicated in the development of the disease to explain the strong inflammatory reactions observed, the activation of monocytes and macrophages, and the induction of proinflammatory cytokines and chemokines detected. Common factors linking some of the possible pathogenetic agents are extrinsically induced tissue stress or heat shock proteins, which react with host tissues and elicit significant T-helper type 1 cell responses.
Conclusion: Based on collected data, we conclude that the microorganisms discussed seem to participate and, at least in part, act as triggers during the course of BD. By clarifying the microbial associations of BD and finding its etiology, particularly the causative antigens leading to BD, it would be easier to suggest more effective treatment and preventive strategies for this disease.

Abstract
Behçet's disease (BD) is a recurrent systemic inflammatory disorder of unknown origin characterized by oral and genital mucous ulcer, uveitis, and skin lesions. Involvement of large vessels, central nervous system (CNS), gastrointestinal tract and thrombotic events are less frequent but can be life threatening. The aim of this review is to provide new insights into the pathogenesis of BD. Over the past year substantial advances have been done in the understanding of the genetic [1,2] and immunology [3] of BD. BD is at the crossroad between autoimmune and autoinflammatory syndromes. In common with autoimmune diseases BD shares class I MHC association. However, in contrast to autoimmune disorders, BD has clinical features that seem to be mostly autoinflammatory. The pathogenesis of BD is still unknown, but major determinants of the genetic and immune system abnormalities have been reported recently. Triggering infectious factors are supposed to participate in the outbreak of BD in genetically predisposed patients. Two recent large genome-wide association study (GWAS) conducted in Turkey and Japan reported association between single nucleotide polymorphism (SNP) of interleukin (IL)-10 and IL-23R/IL-12RB2 genes and BD. New insights into the perturbations of T cell homeostasis of BD recently emerged. We have recently demonstrated the promotion of Th17 responses and the suppression of regulatory T cells (Tregs) that were driven by interleukin (IL)-21 production and that correlates with BD activity. Inflammatory cells within BD inflammatory lesions included mostly neutrophils, Th1 and Th17 cells, and cytotoxic CD8+ and γδ T cells. Altogether, the recent progresses in the knowledge of BD pathogenesis pave the way for innovative therapy.
