Cytokines for monitoring anti-tuberculous therapy: A systematic review

Abstract

The ability to monitor response to therapy for tuberculosis (TB) and confirm adequate treatment would be a major advance. The low reversion rate of interferon-gamma based assays means that they are unlikely to be useful for monitoring therapy. Several exploratory studies have evaluated the diagnostic potential of cytokine biomarkers other than interferon-gamma for monitoring anti-tuberculous therapy. A systematic review of these studies was performed to identify the most promising candidate biomarkers. TNF-α, IL-2, IL-6, IL-10 and IL-12 were the most extensively investigated cytokines. There was significant heterogeneity between studies in relation to study design and laboratory methodology,..
