It often accompanies other autoimmune disorders like rheumatoid arthritis and lupus [<span>1</span>]. Despite its widespread occurrence and significant effect on quality of life, treatment strategies for pSS have traditionally been limited. These strategies have often focused on providing symptomatic relief rather than addressing the underlying disease process. pSS poses a complex challenge in the field of autoimmune disorders, particularly in terms of diagnosis and management. Traditionally, diagnosis has been reliant on clinical assessments and invasive biopsies, with therapeutic interventions limited to symptomatic relief. However, with new biomarkers and novel therapeutic strategies emerging, we are entering a new epoch in managing pSS. These advancements promise to revolutionize the field, offering targeted treatment regimens that could significantly enhance patient outcomes and quality of life [<span>2</span>].</p><p>PSS is characterized by the infiltration of lymphocytes into exocrine glands, which leads to the destruction of glandular tissue and, consequently, functional impairment. The exact cause of the condition remains unclear; however, it is believed that genetic predisposition, environmental triggers, and abnormal immune responses may contribute to its development. PSS is often underdiagnosed or misdiagnosed due to its nonspecific symptoms and overlap with other autoimmune conditions [<span>3</span>]. Traditional diagnostic methods, including subjective dry eye and dry mouth assessments, serological tests for autoantibodies, and salivary gland biopsy, have limitations in terms of invasiveness, specificity, and sensitivity. This underscores the urgent need for reliable, noninvasive biomarkers to improve early diagnosis, assess disease activity, and monitor therapeutic responses [<span>4</span>].</p><p>In pSS, biomarkers play an essential role in early diagnosis, assessment of the severity of the disease, and prediction of the prognosis. A summary of pSS biomarkers is shown in Table 1. The presence of autoantibodies such as SSA (Ro) and SSB (La) is a hallmark of pSS, but newer autoantibodies like ANA, RF, Anti-SP-1, Anti-PSP, Anti-CA-6, Anti-AQP5, and Anti-CarPare are garnering attention for their potential role in the early diagnosis of the disease. Elevated levels of cytokines and chemokines in blood samples, such as CXCL10, IL-6, IL-17A, CXCL13, IL-14a, and BAFF (B-cell activating factor), and decreased levels of CCL28 have been linked to early diagnosis and severe conditions. These not only serve as biomarkers for disease progression but also as potential therapeutic targets. The disease biomarkers are not limited to cytokines and chemokines. Detections of gas, receptors, protein, and RNAs also showed optimum disease prediction ability.
