To have any hope of identifying many different diseases (or causative pathways) within the umbrella definition, a lot of patients are needed; and there are early plans for a study involving a 5,000-strong cohort of patients [this has all gone very quiet!!]. The idea is to explore everything: phenotypes, genotypes, gene expression, cells, cytokines, metabolites and more. Some of these individual features have been researched before, but not all together: and never on such a scale. High quality scientists would then have to be involved to look at applying the new technologies to the data generated from patients. But there has to be a multi-disciplinary approach, and nurses, for example, would be just as important as mathematicians in this operation.
New computer technology would be used to probe the mass of data, with the aim of finding distinct groups of patients who ‘cluster’ together with similar features, which should make it easier to home in on different causal molecular pathways in different types of patients. It is identifiying causal pathways that will lead to a much deeper understanding of ME/CFS and, hopefully, provide targets for drug therapy too.
