Abstract
Background
The Amazon region of Brazil experienced a large epidemic of East Central South African (ECSA) chikungunya virus (CHIKV) in 2017 and continuous transmission of CHIKV persists. The impact of chronic arthritis caused by ECSA CHIKV is unknown.
Objective
The study aim was to describe the duration, severity, and characteristics of CHIKV arthritis in Roraima, Brazil, in comparison with local controls to further understand the long-term rheumatologic impact of ECSA CHIKV infection.
Methods
We performed a cross-sectional analysis comparing clinical arthritis outcomes among 40 cases with chronic (> 3 months) arthritis attributed to their CHIKV disease (n = 40) with control participants who were exposed to CHIKV but did not develop chronic arthritis (n = 40), rheumatoid arthritis controls (n = 40), and healthy controls lacking CHIKV exposure and arthritis (n = 40).
Findings
Our primary finding is that over 2 years post-infection, patients report moderate arthritis disease severity comparable with rheumatoid arthritis with the most significant impact on decreased quality of life from pain.
Main conclusions
These findings suggest that chronic arthritis caused by ECSA CHIKV infection has had a moderate impact in the Americas.
Key Points • Chikungunya infection is responsible for moderate arthritis disease severity. • The East Central South African (ECSA) strain of CHIKV is a cause of persistent arthritis in Roraima, Brazil. |
