A male presenting with polyuria: a case of primary Sjögren syndrome

Sjogren syndrome is a chronic autoimmune disorder with lymphocytic infiltration of exocrine glands causing oral and ocular dryness and well recognized systemic manifestations. Although primary Sjogren syndrome (pSS) is common in women, it is not well recognized in men. This is the first reported case of pSS in a Sri Lankan male to the best of our knowledge. A 58-year-old man presented with polyuria. He has had sicca symptoms for six months and polyuria was secondary to the increased water intake to relieve oral dryness. Examination revealed enlarged tender bilateral salivary glands. After excluding secondary causes, he was diagnosed with pSS. The treatment commenced with steroids, azathioprine, and symptomatic therapy. Primary Sjogren syndrome is an overlooked diagnosis, especially in men, leading to increased morbidity given its multi-organ involvement. Recognition and supportive therapy can help to improve the quality of life of patients.
