Correlation Between Pain, Disease Activity, and Rheumatoid Factor Positivity in Patients with Chikungunya Arthritis.

Chikungunya fever (CHIKF) is an acute viral disease caused by the chikungunya virus (CHIKV) transmitted by mosquitoes. The acute phase presents with limited symptoms and low mortality, but approximately half of cases progress to more chronic illness with persistent and disabling joint symptoms. To better characterize the burden of chronic disease, we analyzed the relationship between pain intensity, the Disease Activity Index by DAS28-ESR, rheumatoid factor (RF) positivity, sex, and age in a retrospective cohort of 133 patients with chikungunya arthritis (CHIKA).

Bone erosions and joint damage caused by chikungunya virus: a systematic review.

Background: Chikungunya fever is an emerging global infection transmitted by Aedes mosquitoes that manifests as an acute febrile illness with joint pain and can lead to chronic arthritis. The mechanism underlying chronic joint damage remains unclear; however, chronic chikungunya arthritis shares similarities with rheumatoid arthritis. Disease-modifying antirheumatic drugs have revolutionized rheumatoid arthritis treatment by preventing joint damage.

Chikungunya Arthritis Treatment with Methotrexate and Dexamethasone: A Randomized, Double-blind, Placebo-controlled Trial.

Background: Chikungunya fever is a reemerging epidemic disease caused by a single-stranded RNA alphavirus transmitted throughout by Aedes mosquitoes. Chikungunya virus infection is a biphasic disease in which 72% to 95% of affected individuals manifest acute chikungunya fever. Following the acute phase, more than 40% of affected individuals develop arthritis, often lasting more than 3 months, referred to as chronic chikungunya arthritis, which frequently mimics rheumatoid arthritis.

Quality of Life and Disability in Chikungunya Arthritis.

Background: Chikungunya virus infection, transmitted by Aedes mosquito vectors, causes outbreaks of chikungunya fever (CHIKF), throughout the tropical and subtropical world. Following acute infection, many CHIKF patients develop a second phase, chronic and disabling arthritis.

Objective: To evaluate the impact of chikungunya arthritis (CHIKA) on quality of life and disability in a cohort of Brazilian CHIKA patients.

Therapy for Chikungunya Arthritis: A Study of 133 Brazilian Patients.

Chikungunya fever is a global vector-borne viral disease. Patients with acute chikungunya are usually treated symptomatically. The arthritic phase may be self-limiting.

A Case Report of Chikungunya Fever, Rheumatoid Arthritis, and Felty's Syndrome.

Introduction: Chronic chikungunya (CHIK) arthritis, an inflammatory arthritis, often follows acute CHIK fever (CHIKF), a viral infection. The pathogenesis of chronic CHIK arthritis is poorly characterized, but may resemble other forms of inflammatory arthritis. Clinically, chronic CHIK arthritis sometimes mimics rheumatoid arthritis (RA).
