Disease activity score for still's disease.

Objective: To develop the Still's Disease Activity Score (SDAS).

Methods: We used data from the prospective adult-onset Still's disease cohort study and evaluated the disease activity. An expert group selected the most frequent, reproducible, and objective variables significantly modified in statistical analysis when comparing patients in the active group and in the remission group.

Proposal of a new diagnostic algorithm for adult-onset Still's disease.

Objective: This study was performed to develop a new diagnostic algorithm for adult-onset Still's disease (AOSD).

Methods: We conducted a multicenter prospective nationwide case-control study in tertiary Internal Medicine, Rheumatology, and Infectious Diseases departments, to include successively patients with suspected AOSD based on the presence of two or more major criteria of Yamaguchi and/or Fautrel classifications. Patients were classified as AOSD or controls according to a predefined procedure.

Validation of the neutrophil-to-lymphocyte ratio as a new simple biomarker of adult onset Still's disease: A STROBE-Compliant prospective observational study.

This study was performed to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of adult onset Still disease (AOSD) and its performance to improve the sensitivity of the classifications criteria (Yamaguchi and Fautrel Classifications). We conducted a multicenter prospective nationwide case-control study in Internal medicine, Rheumatology and Infectious disease departments, to include successively patients with suspected AOSD (2 or more major criteria of Yamaguchi or Fautrel classifications). All clinical and biological features were collected in a consensual and standardized clinical assessment at baseline and during follow-up.
