1. What is the ACR/EULAR SLE Classification Criteria?

The ACR/EULAR (American College of Rheumatology/European Alliance of Associations for Rheumatology) classification criteria for systemic lupus erythematosus (SLE) provides a standardized method for classifying patients with this autoimmune disease. The criteria include various clinical and immunological domains with weighted scores.

2. How Does the Calculator Work?

The calculator sums points from various criteria:

Score = sum of points for criteria (e.g., ANA 10, lupus nephritis 10, etc.)

Entry criterion: ANA titer ≥1:80 is required for classification
Classification threshold: Total score ≥10 points

3. Importance of SLE Classification

Details: Accurate classification is crucial for clinical trials, epidemiological studies, and ensuring consistent diagnosis across different healthcare settings. The ACR/EULAR criteria provide improved sensitivity and specificity compared to previous classification systems.

4. Using the Calculator

Tips: Select appropriate options for each criterion. Note that ANA titer ≥1:80 is required as an entry criterion, and the total score must be ≥10 for SLE classification.

5. Frequently Asked Questions (FAQ)

Q1: What is the purpose of these classification criteria?
A: The criteria help standardize patient classification for research studies and clinical trials, ensuring consistent inclusion criteria across different studies.

Q2: Are these criteria used for diagnosis?
A: While helpful, these are classification criteria, not diagnostic criteria. Clinical judgment remains essential for individual patient diagnosis.

Q3: Why is ANA ≥1:80 required?
A: This serves as an entry criterion because nearly all SLE patients have positive ANA, though positive ANA can occur in other conditions and healthy individuals.

Q4: What's the difference from previous criteria?
A: The 2019 ACR/EULAR criteria have improved sensitivity (93%) and specificity (93%) compared to previous criteria, with better performance across diverse populations.

Q5: Can this calculator replace clinical assessment?
A: No, this is a tool to assist with classification. Final diagnosis should be made by qualified healthcare professionals considering the full clinical picture.
