British Isles Lupus Assessment Group (BILAG) developed an index for evaluating disease activity in patients with systemic lupus erythematosus (SLE). This was based on the physician's intent to treat. The authors are from multiple universities in Great Britain.
Patient selection: SLE
Organ-based components:
(1) general
(2) mucocutaneous
(3) neurological
(4) musculoskeletal
(5) cardiopulmonary (cardiovascular/respiratory)
(6) vascular
(7) renal
(8) hematological

marked activity |

B |

C |

D |
0 |
no activity ever |
E |

number of components with marked activity =
= SUM(number of components with marked activity)
number of components with moderate or marked activity =
= SUM(number of components with marked activity, number of components with moderate activity)
total score =
= SUM(points for all 8 components)
Interpretation:
• minimum total score: 0
• maximum total score: 72
• minimum number of components with marked activity: 0
• maximum number of components with marked activity: 8
• minimum number of components with moderate or marked activity: 0
• maximum number of components with moderate or marked activity: 8
• The higher the scores the greater the disease activity.
