Her medical history was notable for a diagnosis of seronegative RA, established in April 2018, based on the presence of symmetrical inflammatory polyarthritis involving the small joints of the hands, prolonged morning stiffness exceeding one hour, and elevated inflammatory markers-C-Reactive protein (CRP) at 28 mg/L and erythrocyte sedimentation rate (ESR) of 52 mm per hour, in the absence of detectable rheumatoid factor (RF) or anticitrullinated protein antibody (ACPA). This evidence concerns the gene CRP and rheumatoid arthritis.
