Infections and systemic lupus erythematosus.

Area of Science:

• Immunology
• Infectious Diseases
• Rheumatology

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse clinical presentations.
• SLE progression is variable, marked by exacerbations, remissions, and potential for severe outcomes.
• The precise etiopathogenesis of SLE remains incompletely understood.

Purpose of the Study:

• To explore the association between infections and the onset or exacerbation of SLE.
• To investigate the potential causative or protective roles of specific infectious agents in SLE.
• To highlight the need for further research into the interplay between infections and autoimmunity.

Main Methods:

• Literature review focusing on infectious agents and their link to SLE.
• Analysis of proposed mechanisms for infection-induced autoimmunity.
• Examination of evidence for both causative and protective roles of infections.

Main Results:

• Infections, including Epstein-Barr virus (EBV), parvovirus B19, retroviruses, and cytomegalovirus (CMV), are strongly linked to SLE.
• Infections can potentially trigger or exacerbate SLE, but some may also offer protection.
• The interaction between microorganisms and the host immune system is complex and influences autoimmune outcomes.

Conclusions:

• Infectious agents are implicated in the pathogenesis of SLE, with specific viruses playing a potential role.
• The dual role of infections (causative or protective) in SLE requires further investigation.
• Understanding these interactions is crucial for managing SLE and its autoimmune sequelae.
