ACR 2012 Special Report 4

ACR Special Report: Chicago, IL 2011

Update on Biomarkers

A holy grail of lupus is to identify a panel of blood tests that can tell physicians how a patient’s disease will progress and what treatments would be most beneficial. This is particularly difficult given that the disease presents so differently in so many patients. But a poster presented at the ACR meeting by researchers at the Hospital for Special Surgery in New York City, including ALR Scientific Advisory Board Chair Mary “Peggy” Crow, MD, reports on a recent study that may eventually provide that information.ix

The researchers conducted genetic analyses and measured levels of 44 autoantibodies and pro-inflammatory cytokines on 169 blood samples from 23 patients with lupus and 5 healthy donors that had been collected over 3 years. The two most common gene signatures were type 1 interferon (IFN-1) inducible genes and neutrophil granule-related genes. Patients with neither gene signature had only mild disease; while those with both the IFN-1 and neutrophil signatures were more likely to experience vascular complications such as cardiovascular and kidney damage, and much higher levels of anti-SSA/Ro autoantibodies. Patients who expressed the IFN-1 signature only were more likely to have mucocutaneous manifestations, such as those affecting the skin, scalp, and nails, and much higher levels of tumor necrosis factor.

Key point: This study provides promising data on the potential of a biomarker panel to identify subsets of lupus disease that could guide treatment decisions. Additional clinical trials are necessary, however.
