In December 2019, the world began to face a new reality. A new virus appears, and with it a new pandemic that is unprecedented for humanity. The global spread of COVID-19 can be described as the worst pandemic in humanity in the last century.
The first moment was of worry and reflection: what would be the next steps? What are the possible forms of combat? What is the behavior of the virus? How is the pathophysiology of the disease? There were months of intense study. Several research centers have come together brilliantly to produce results. Never in the history of science have results been generated and published so quickly. So, science has advanced a lot in just six months.
The great lesson I see from these months of the pandemic is that undoubtedly, it is time for individualized medicine.
The virus behaves completely differently in each individual. For the majority, it goes completely unnoticed, in others it causes a brief and inconvenient discomfort and for a significant but smaller percentage of individuals it is overwhelming and lethal. So, the “one fits all” approach, is no longer the best in this pandemic.
Obesity is one of the most important conditions that increases exponentially the mortality risk of SARS-CoV-2 patients. And this is the second epidemic we face in the world today. Besides obesity, diabetes, hypertension, heart conditions and another chronic disease increase the complications of the disease. Literature data demonstrate that there is a direct metabolic link between the state of inflammation and the “cytokine storm” contributing to the respiratory decline of COVID-19.
In the context of individualized medicine, the analysis of genetic polymorphisms can be an important tool to the prevention and possible aggravation of the disease. The analysis of genetic risk for obesity, diabetes, hypertension and nutritional deficiencies, can help patients and health professionals in making decisions regarding the health protocols to be taken.
Hypothesis-driven approaches to assess variants of specific, metabolically relevant genes in subjects enrolled in nutritional interventions can improve health and prevent complications.
In this scenario, where science has progressed more and more and with an emphasis on genomics and telemedicine, we have the ideal moment for the implementation of individualized medicine. The patient increasingly wants to take control and responsibility for his own health and the knowledge of his own DNA creates empowerment when health has never been so important.
