Blood Count-derived Immunoinflammatory Markers in Thyroidassociated Ophthalmopathy

Area of Science:

• Ophthalmology
• Immunology
• Hematology

Background:

• Thyroid-associated ophthalmopathy (TAO) is an autoimmune condition affecting the eyes.
• Systemic immunoinflammatory parameters derived from blood counts are increasingly recognized for their role in various diseases.

Purpose of the Study:

• To evaluate the diagnostic and prognostic value of blood-count derived systemic immunoinflammatory parameters in patients with TAO.

Main Methods:

• A retrospective case-control study involving 46 TAO patients and 46 controls.
• Analysis of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio, and systemic immune-inflammatory index (SII).
• Assessment of associations between these parameters and clinical outcomes in TAO patients.

Main Results:

• Significant differences in NLR, PLR, SII, and lymphocyte count were observed between TAO patients and controls (p < 0.05).
• These inflammatory parameters showed no significant prognostic effect on TAO clinical outcomes.
• Lower initial platelet count and PLR were associated with the need for systemic treatment in TAO patients during follow-up (p = 0.001 and p = 0.02, respectively).
• Initial platelet count was significantly linked to subsequent steroid requirement (β = -0.02, p = 0.03).

Conclusions:

• NLR, PLR, and SII may serve as potential diagnostic markers for TAO.
• These markers lack significant prognostic value for TAO outcomes.
• A lower initial platelet count in TAO patients might indicate a higher likelihood of requiring systemic therapy.
