Enteric Microorganisms in Rheumatoid Diseases: Causative Agents and Possible Mechanisms

Area of Science:

• Immunology
• Gastroenterology
• Rheumatology

Background:

• Seronegative spondarthropathies, including ankylosing spondylitis, Reiter's disease, and reactive arthritis, are associated with HLA-B27.
• Genetic predisposition is suggested by HLA-B27 prevalence, but environmental factors are also implicated.

Purpose of the Study:

• To discuss the role of foodborne enteric pathogens in the development of three seronegative spondarthropathies.
• To clarify the relationships within seronegative arthropathies through a clinical profile.
• To examine the evidence linking enteric pathogens to these conditions post-gastrointestinal illness.

Main Methods:

• Literature review and synthesis of existing evidence.
• Clinical profile analysis to delineate disease relationships.
• Examination of molecular and general mechanisms of disease and immune response.

Main Results:

• Foodborne enteric pathogens are implicated as triggers for seronegative spondarthropathies.
• Gastrointestinal illness can precede the onset of these arthropathies.
• Interactions between genetic factors (HLA-B27) and environmental exposures (pathogens) are crucial.

Conclusions:

• Enteric pathogens play a significant role in the etiology of seronegative spondarthropathies.
• Understanding these pathogen-host interactions is key to managing and preventing these conditions.
• Further research into molecular mechanisms can elucidate disease pathogenesis and inform therapeutic strategies.
