Biomarkers are indicators of biological processes. In lupus we especially require activity biomarkers to look at pre- dicting flares, differentiating damage from activity, and assessing response to treatment. There are numerous mol- ecules that have been evaluated for these purposes, but studies suffer from limitations of design, statistical rigor, and outcome measure. The best biomarker remains the oldest one, double-standard deoxyribonucleic acid (dsDNA) and has many longitudinal studies to back it, and shows the ability to predict renal flares. Apart from this anti-C1q, cell-bound complement activation products and urinary molecules-chemokines and neutrophil gelatinase-associated lipocalin (NGAL)-are promising. The interferon signature has not lived up to its promise; however, microRNA (miRNA) signature is newly coming up as a marker of activity. Even if we do come up with better biomarkers, there is lack of clarity on issues of socio-economic impact as well as psychological impact of frequent testing for biomarkers.
