Lung function data of North-African patients with rheumatoid arthritis: a comparative study between anti-citrullinated peptides antibodies positive and negative patients.

Introduction: Although lung damages are among the leading causes of death from Rheumatoid Arthritis (RA), few studies have assessed the spirometric and plethysmographic data and profile of patients with RA, particularly those with Anti-Citrullinated Peptides Antibodies Positive (ACPA+).

Aim: To compare the spirometric and plethysmographic data and profile of RA patients ACPA+ and ACPA-.

Methods: This comparative pilot study was performed over a two-year period (2018-2019) in Algiers (Algeria).
