Background:Rheumatoid arthritis (RA) is an autoimmune disease, which mistakenly attacks the joints and induces the inflammatory changes that thicken the joints (the synovium) resulting in swelling and pain in and around the joints. It causes pain, joint deformity, and also affects the quality of life. The joint is affected symmetrically. It also can affect body systems, such as the cardiovascular, respiratory systems, or other systems, which manifest as extra-articular manifestations. Extra-articular manifestations of RA are documented less in India hence this study was undertaken to correlate RA with extra-articular manifestations as well as its relationship with serostatus in patients with extra-articular manifestations.Materials and Methods:Sixty patients (age between 18–60 years) attending Medicine/Rheumatology outpatient department were included in the study (12 months) who fulfilled the 2010 RA classification criteria laid down by American College of Rheumatology (ACR)/European League against Rheumatism (EULAR) for RA. All the subjects underwent a thorough history, clinical examination, and laboratory investigations. The relevant data were analyzed with appropriate statistical methods after 12 months’ duration.Results:Nearly 68.33% of the subjects were found to have extra-articular manifestations mostly in the age group of 31–40 years with prevalence higher in the female. In the seropositive patients, early morning stiffness (EMS) constitutes 63.82% of the total extra-articular manifestations in the patients followed by anemia (38.29%) and peripheral neuropathy (34.04%). On the other hand, in the seronegative cases, EMS (61.53%) followed by anemia (23.07), peripheral neuropathy (15.38%), and keratoconjunctivitis sicca (15.38%). Extra-articular manifestations in seropositive patients have a statistically significant relationship with the increase in the duration of the disease.Conclusion:Extra-articular manifestations need to be looked carefully as it is associated with more severe disease. Seropositivity and extra-articular manifestations both usually indicate that the RA is more severe and may affect the quality of life.
