British Isles Lupus Assessment Group (BILAG) developed an index for evaluating disease activity in patients with systemic lupus erythematosus (SLE). The index is based on several findings, each of which is categorized. The authors are from multiple universities in Great Britain.
Patient selection: followup assessment
Severe manifestations - key findings:
(1) proteinura (see above)
(2) active urine sediment
(3) histological evidence of active nephritis
Severe manifestations - additional:
(4) hypertension (see above)
(5) renal function (see above)
Moderate manifestations:
(1) proteinuria (see above)
(2) renal function (see above)
Mild manifestations:
(1) proteinuria (see above)
(2) hypertension
History:
(1) history of previous renal disease

Purpose: To grade the severity of renal involvement on a followup visit in a patient with systemic lupus erythematosus (SLE) using the BILAG criteria.
Specialty: Immunology/Rheumatology
Objective: severity, prognosis, stage, differential diagnosis and mimics, red flags, disease progression, prevention
ICD-10: M32,
