Systems Medicine: Sketching the Landscape

Abstract

To understand the meaning of the term Systems Medicine and to distinguish it from seemingly related other expressions currently in use, such as precision, personalized, -omics, or big data medicine, its underlying history and development into present time needs to be highlighted. Having this development in mind, it becomes evident that Systems Medicine is a genuine concept as well as a novel way of tackling the manifold complexity that occurs in nowadays clinical medicine-and not just a rebranding of what has previously been done in the past. So looking back it seems clear to many in the field that Systems Medicine has its origin in an integrative method to unravel biocomplexity, namely, Systems Biology. Here scientist by now gained useful experience that is on the verge toward implementation in clinical research and practice.Systems Medicine and Systems Biology have the same underlying theoretical principle in systems-based thinking-a methodology to understand complexity that can be traced back to ancient Greece. During the last decade, however, and due to a rapid methodological development in the life sciences and computing/IT technologies, Systems Biology has evolved from a scientific concept into an independent discipline most competent to tackle key questions of biocomplexity-with the potential to transform medicine and how it will be practiced in the future. To understand this process in more detail, the following section will thus give a short summary of the foundation of systems-based thinking and the different developmental stages including systems theory, the development of modern Systems Biology, and its transition into clinical practice. These are the components to pave the way toward Systems Medicine.

“…Despite all the advances and elucidation of a vast amount of molecular mechanisms, onedisease one-target paradigm has its limits and new trends of pharmacology such as polypharmacology and drug repurposing have developed to cure complex diseases which can rarely be due to an impairment or dysfunction in just one gene or molecule [7]. Recently, the deficiencies of the dominant reductionism in medical research have become more evident, resulting in attention towards systems biology to understand the complex interconnections within biological systems [8][9][10][11][12][13][14][15][16][17][18][19].…”

The 4-H of Biomarkers in Arthritis: A Lot of Help, Occasional Harm, Some Hype, Increasing Hope

“…While signatures generated using these methods appear simple, clinicians are not equipped to apprehend how complex these computer-generated biomarkers are and what they mean. The ultimate objective of these composite biomarkers is "systems medicine," integrating biochemical, physiological, and environmental interactions 18 . Yet questions remain: will patients benefit from this techno -logy-driven explosion of biomarkers and do we prepare adequately for them?…”

Sensitivity and robustness of comorbidity network analysis

“…Systems medicine consists in the adoption into medical research of principles and techniques from systems biology, which in turn are described as global, integrative, and holistic (Hood et al 2013;Ayers and Day 2015;Kirschner 2016). Networks are a prime illustration, having become a staple of systems biology (Pavlopoulos et al 2011) and seen extensive use in systems medicine (Gietzelt et al 2016).…”
