    Abstract: Huntington’s disease (HD) is a fatal, inherited, neurodegenerative disorder, characterized by chorea, motor instabilities, psychiatric manifestations and cognitive decline. Early genetic testing provides an opportunity for clinical interventions aimed at delaying onset and/or slowing progression of disease; however, current treatments for HD are limited, with only two FDA-approved drugs available to manage chorea. Encouragingly, however, several disease-modifying treatment approaches are in the therapeutic pipeline, with more than 200 clinical studies, and many more preclinical studies, in the works. Robust and reliable biomarkers are needed to predict disease onset, monitor disease progression and assess treatment responses. More specifically, biomarkers to stratify patients for clinical trials and biomarkers to track drug efficacy will certainly lead to improved clinical trial design and success. This book represents the first book focused solely on biomarkers for HD and represents a distinct resource that will be informative, not only for clinicians and those involved in clinical trial design, but also for a wide range of neurodegenerative disease researchers. This edited volume is written by top leaders in the field, and takes a cross-disciplinary approach to cover a broad spectrum of biomarker types, in order to provide the latest advances in the development of biochemical, molecular, imaging and digital biomarkers that have been investigated for HD. With the ultimate goal of treating patients, the development of disease-associated biomarkers has never been more important.

    Description: Growing evidence suggests that inflammatory responses, in both the brain and peripheral tissues, contribute to disease pathology in Huntington’s disease (HD), an inherited, progressive neurodegenerative disorder typically affecting adults in their 30–40 s. Hence, studies of inflammation-related markers in peripheral fluids might be useful to better characterize disease features. In this study, we measured levels of C-reactive protein (CRP), Interleukin-6 (IL-6), interleukin 1 beta (IL-1B), and alpha-amylase (AA) in saliva and plasma from n = 125 subjects, including n = 37 manifest HD patients, n = 36 premanifest patients, and n = 52 healthy controls, using immunoassays. We found increases in salivary levels of IL-6, IL-1B and CRP across different disease groups and increased levels of IL-6 in the plasma of HD patients as compared to premanifest patients and controls. The levels of salivary IL-6 were significantly correlated with each of the other salivary markers, as well as with IL-6 levels measured in plasma. Further, salivary IL-6 and IL-1B levels were significantly positively correlated with Total Motor Score (TMS) and chorea scores and negatively correlated with Total Functional Capacity (TFC) in HD patients, whereby in healthy control subjects, IL-6 was significantly negatively correlated with Montreal Cognitive Assessment (MoCA) and the Symbol Digit Modalities test (SDM). Interestingly, the plasma levels of IL-6 did not show similar correlations to any clinical measures in either HD or control subjects. These findings suggest that salivary IL-6 is particularly relevant as a potential non-invasive biomarker for HD symptoms. The advent of an effective, dependable salivary biomarker would meet the urgent need for a less invasive means of identifying and monitoring HD disease progression.
