[Viral arthritis and vasculitis].

Area of Science:

• Rheumatology
• Infectious Diseases
• Virology

Background:

• Viral arthritis and vasculitis are crucial differential diagnoses in patients presenting with acute polyarticular arthritis, especially when accompanied by fever and rash.
• Specific populations, including those at high risk and returning travelers, warrant particular attention.
• While Parvovirus B19 is a leading cause in Europe, the prevalence of rubella, hepatitis B, and C viruses has decreased.

Purpose of the Study:

• To highlight the significance of viral arthritis and vasculitis as differential diagnoses.
• To emphasize the evolving landscape of viral causes, including the increasing relevance of arthritogenic alphaviruses due to global travel.
• To underscore the importance of recognizing these conditions for timely diagnosis and management, as they can indicate treatable viral infections.

Main Methods:

• Literature review and synthesis of current knowledge on viral arthritis and vasculitis.
• Analysis of etiological factors, clinical presentations, and epidemiological trends.
• Discussion of diagnostic considerations and therapeutic implications.

Main Results:

• Parvovirus B19 is the most common cause of viral arthritis in Europe.
• Arthritogenic alphaviruses are gaining prominence due to international travel.
• Viral arthritis is typically self-limiting, often requiring symptomatic treatment with NSAIDs for pain management.

Conclusions:

• Viral arthritis and vasculitis necessitate careful consideration in specific clinical scenarios.
• The etiologic spectrum of viral arthritis is dynamic, influenced by factors like global travel.
• Prompt diagnosis is essential as arthritis and vasculitis can be manifestations of treatable viral infections such as Hepatitis B, C, and HIV.
