References. SLE Criteria: 61. PRAAS/CANDLE: 3, 13–23, includes 4 previously unpublished patients evaluated or reviewed at NIH, and clinical updates from evaluation at NIH on 8 patients. SAVI: 4, 26–29 with clinical updates on 4 patients, 1 previously unpublished patient evaluated at NIH. MonoSLE: DNASE1 deficiency, n = 2 (10), C1q deficiency, n = 50–100 (9, 82, 85–88), DNASE1L3 deficiency, n = 17 (11).
Four or more of the 11 criteria are needed for diagnosis of SLE. Clinical features that are more specific for SLE and are typically not observed in SAVI are depicted in black. In SLE, these are triggered by immune complex deposition. Features in gray are less specific for SLE and can be triggered by mechanisms other than immune complex deposition (i.e., hematologic manifestations seen in SLE can be caused by autoantibodies directed to cell subsets or by bone marrow suppression aggravated by the release of type I IFN). Antibodies to cardiolipin can often be present in patients with other immune dysregulatory diseases and are less specific for SLE. Rare indicates reported in less than 20 % of cases that report on the feature
Evidence of immune complex deposition has been reported
Multifactorial or nonspecific findings in isolation
Antibodies specific to SLE are detected shortly before the development of specific organ disease
CANDLE: oral ulcers n = 1, pericarditis n = 1, seizures n = 2, nephrotic syndrome unknown etiology n = 1, Coombs positive anemia n = 1, SAVI: oral ulcers in 4/5 with 1 associated with recurrent HSV labialis. ANA titers fluctuate (inconsistently positive) and do not correlate with disease activity in CANDLE n = 12, SAVI n = 8
Seizures are a common feature in AGS as part of primary encephalopathy
