Despite growing research efforts, no reliable biomarker currently exists for the
diagnosis and prognosis of multiple system atrophy (MSA). Such biomarkers are
urgently needed to improve diagnostic accuracy, prognostic guidance and also to
serve as efficacy measures or surrogates of target engagement for future clinical
trials. We here review candidate fluid biomarkers for MSA and provide
considerations for further developments and harmonization of standard operating
procedures. A PubMed search was performed until April 24, 2015 to review the
literature with regard to candidate blood and cerebrospinal fluid (CSF)
biomarkers for MSA. Abstracts of 1760 studies were retrieved and screened for
eligibility. The final list included 60 studies assessing fluid biomarkers in
patients with MSA. Most studies have focused on alpha-synuclein, markers of
axonal degeneration or catecholamines. Their results suggest that combining
several CSF fluid biomarkers may be more successful than using single markers, at
least for the diagnosis. Currently, the clinically most useful markers may
comprise a combination of the light chain of neurofilament (which is consistently
elevated in MSA compared to controls and Parkinson’s disease), metabolites of the
catecholamine pathway and proteins such as α-synuclein, DJ-1 and total-tau.
Beyond future efforts in biomarker discovery, the harmonization of standard
operating procedures will be crucial for future success.
