Activity and Damage Indices for Sjögren's Disease

Area of Science:

• Rheumatology
• Immunology
• Autoimmune Diseases

Background:

• Primary Sjögren's disease (SjD) presents with diverse clinical features, complicating management and outcome assessment.
• Disease activity in SjD involves both systemic manifestations and patient-reported outcomes (PROs).
• Existing assessment tools like ESSDAI and ESSPRI have limitations in capturing the full spectrum of SjD activity.

Purpose of the Study:

• To review current Sjögren's disease assessment tools.
• To highlight the need for composite outcomes and validated damage assessment methods.
• To emphasize the importance of comprehensive evaluation for disease progression and treatment impact.

Main Methods:

• Review of existing Sjögren's disease activity indices (ESSDAI, ESSPRI).
• Discussion of composite outcome measures (STAR, CRESS).
• Analysis of the unmet need for damage assessment in SjD.

Main Results:

• Current indices like ESSDAI and ESSPRI have limitations and do not fully capture disease activity or patient burden.
• Composite scores (STAR, CRESS) integrate multiple parameters for a more comprehensive assessment.
• A validated method for assessing irreversible damage in SjD is currently lacking.

Conclusions:

• Sjögren's disease assessment requires complementary tools for systemic activity and PROs.
• Composite scores represent a recent innovation for comprehensive disease activity evaluation.
• Validated damage assessment is crucial for fully evaluating Sjögren's disease progression and therapeutic impact.
