Non-alcoholic fatty liver disease and Atherosclerosis at a crossroad:The overlap of a theory of change and bioinformatics

更新时间:2023-05-28

【摘要】Atherosclerosis(ATH) and non-alcoholic fatty liver disease(NAFLD) are medical conditions that straddle a communal epidemiology, underlying mechanism and a clinical syndrome that has protean manifestations, touching every organ in the body. These twin partners, ATH and NAFLD, are seemingly straightforward and relatively simple topics when considered alone, but their interdependence calls for more thought. The study of the mutual relationship of NAFLD and ATH should involve big data analytics approaches, given that they encompass a constellation of diseases and are related to several recognized risk factors and health determinants and calls to an explicit theory of change, to justify intervention. Research studies on the "association between aortic stiffness and liver steatosis in morbidly obese patients", published recently, sparsely hypothesize new mechanisms of disease, claiming the "long shadow of NAFLD"as a risk factor, if not as a causative factor of arterial stiffness and ATH. This statement is probably overreaching the argument and harmful for the scientific credence of this area of medicine. Despite the verification that NAFLD and cardiovascular disease are strongly interrelated, current evidence is that NAFLD may be a useful indicator for flagging early arteriosclerosis, and not a likely causative factor. Greater sustainable contribution by precision medicine tools, by validated bioinformatics approaches, is needed for substantiating conjectures,assumptions and inferences related to the management of big data and addressed to intervention for behavioral changes within an explicit theory of change.
