Abstract

BACKGROUND: Primary Sjogren’s syndrome is a system chronic autoimmune disorder, it's a etiology is still not well understood. The syndrome is characterized by lymphocytic infiltrates in exocrine organs. There has been no previous prevalence study about Sjogren’s syndrome in Iraq.OBJECTIVE: To determine the prevalence rate of primary Sjogren’s syndrome among Rheumatology clinic patients in Iraq.PATIENTS AND METHODS:A cross –sectional Rheumatology clinic – based survey was performed on 1000 consecutive patients aged 18-70 years attending rheumatology clinic during the first 9 months of the year 2019. Patients fulfilling the 2002 criteria for the classification of Sjogren’s syndrome, and those fulfilling the 2010 criteria for classification of rheumatoid arthritis were recorded to estimate the prevalence of primary Sjogren’s syndrome.RESULTS: Among the 1000 studied adult rheumatic disease pateints attending the rheumatology clinic, there were 98 pateints diagnosed as primary Sjogren’s syndrome and 165 patients diagnosed as rheumatoid arthritis. By compairing the prevalence of primary Sjogren’s syndrome with that of rheumatoid arthritis and extrapolating of data, we found that the estimated prevalence of pSS is 0.59% of population, which is more common in elderly females. It comes next only to rheumatoid arthritis in frequency among connective tissue diseases in Iraq. CONCLUSION: Primary Sjogren’s estimated prevalence is 0.59% of the population, and was more common in elderly females.
