COVID-19 Risk: Clinical Tools for Assessing and Personalizing Immunity.

Bland, Jeffrey S

Researchers and clinicians all over the world are struggling to bring the spread of SARS-CoV-2 under control. Whether we refer to COVID-19 as a pandemic (a widely used word) or a syndemic (a new emerging term), we now know that specific immunotypes have been linked to both risk to infection and presentation of this disease. Application of assessment tools that support a fuller understanding of individual immune system status is next-level care that providers must prepare for and deliver. Commonly used biometric devices already gather data that can be relevant and useful to a phenotypic evaluation of immune function. These variables include pulse rate, blood oxygenation, sleep cycles, respiration rate, heart rate variability, continuous blood glucose monitoring, and ambulatory blood pressure. When coupled with traditional blood analytes and measurements of nutrient status, a more complete picture of immunological function may be revealed. Innovative questionnaires and algorithms can also be helpful additions to a clinician's toolkit. In a therapeutic relationship between provider and patient, this approach may lead to options for personalized immune intervention using diet, medical nutrition, and lifestyle medicine.
