Parvovirus B19 in Rheumatic Diseases.

Area of Science:

• Virology and Immunology
• Rheumatology

Background:

• Parvovirus B19 (B19V) is a widespread human pathogen in the Parvoviridae family.
• B19V infects erythroid progenitor cells (EPCs), causing apoptosis and diverse clinical manifestations.
• It can also infect non-permissive cells, altering their physiology and contributing to pathogenesis.

Purpose of the Study:

• To provide fundamental information on Parvovirus B19.
• To highlight viral infection characteristics in permissive and non-permissive cellular systems.
• To focus on recent findings regarding B19V's pathogenic role in rheumatologic diseases.

Main Methods:

• Review of existing literature on Parvovirus B19.
• Analysis of viral-cellular interactions in different cell types.
• Synthesis of evidence linking B19V to autoimmune rheumatologic conditions.

Main Results:

• B19V infection leads to EPC apoptosis and can affect other cell types.
• Joint involvement is a common symptom in adult B19V infections.
• Emerging evidence suggests B19V's potential role in rheumatoid arthritis, juvenile idiopathic arthritis, systemic sclerosis, SLE, and vasculitis.

Conclusions:

• Parvovirus B19 exhibits diverse pathogenic mechanisms based on host cell interactions.
• B19V is increasingly implicated in the pathogenesis of several autoimmune rheumatologic diseases.
• Further research is warranted to elucidate the precise role of B19V in these conditions.
