HRR as a Novel Biomarker in Sjögren's Syndrome

Sjögren's syndrome (SS) is an autoimmune disorder characterized by chronic salivary and lacrimal gland dysfunction leading to dry mouth (xerostomia) and dry eye (xerophthalmia) sensation (1). Although dry mouth and dry eye are the main symptoms, the disease may influence many organs and systems. Diagnosis is made with ocular surface staining scores, anti-SS-A/SS-B auto-antibody positivity, and minor salivary gland biopsy (2). The Complete blood count (CBC) is a simple, inexpensive, accessible, and routinely used laboratory parameter that can be linked to oxidative stress, inflammation and microvascular flow resistance. Parameters include NLR and PLR values may be calculated by using CBC parameters (3). Neutrophil/lymphocyte ratio is used as an inflammatory marker in the diagnosis and prognosis of many cardiovascular diseases, malignancies, and infections (4-6). Peripheral inflammatory biomarkers of hematologic indices had been suggested by numerous studies to play a role during SS onset and progression.
