Adult-onset Still's disease preceded by influenza vaccination: Coincidence or true association?

Abstract

Background: Influenza vaccine has rarely been associated with the occurrence of systemic inflammatory diseases.

Objective: To present a case of adult-onset Still's disease (AOSD) following influenza vaccination, and subsequently explore the possible association between AOSD and influenza vaccination, as well as implications for clinical practice.

Methods: Case report.

Results: We report a case of 20-year-old woman who developed typical AOSD, characterized by spiking fever, arthritis and salmon-pink rash, one week after influenza vaccination. She responded well to systemic corticosteroids therapy. This is the first case report of influenza vaccination-associated AOSD from Thailand.

Conclusions: Influenza vaccination may be a trigger of AOSD but more data are needed to confirm the association. History of recent vaccination should be explored in patients suspected of having systemic inflammatory diseases including AOSD.
