Smoking is one of the important factors that increase the risk of RA infections by aiding in citrullinated protein production, CRP increases in RA patients and binds with the severity of the disease. The aim of the study is to evaluate the CRP and smoking effects on RA patients. 150 blood samples were taken; 100 for RA patients and 50 for healthy control, the patients were taken from the Baghdad Teaching Hospital / Rheumatologically Consulting Clinic in the period from November 2021 to February 2022.
