Brief Summary:
The acceleration of population aging and the improved management of comorbidities lead to an increase in the number of multi-pathological elderly patients admitted to geriatric services. This is an extremely specific population in terms of immunology due to the presence of immunosenescence (physiological aging of the immune system) and the potential additional effect of multiple chronic pathologies (comorbidities) presented by these patients.
The specific effect of multiple chronic pathologies on the immune status of elderly patients is currently underexplored because most studies on immune system aging only include elderly patients who do not have comorbidities or treatments that could impact the immune system (e.g. SENIEUR protocol). Therefore, their results are not applicable to patients in geriatric services.
The decrease in monocyte expression of HLA-DR (mHLA-DR) has been studied as a marker of immune alteration in intensive care units in the context of sepsis, but also in chronic pathologies (e.g. cancer, diabetes, renal insufficiency). These chronic pathologies are frequently found in elderly subjects.
The objective of the study would therefore be to investigate the relative contribution of age (immunosenescence) and comorbidities to the alteration of the immune status of geriatric patients through the measurement of mHLA-DR.
To date, no study has explored mHLA-DR in a population of multi-pathological geriatric patients. Our work aims to generate initial data through a pilot study in hospitalized multi-pathological subjects over 75 years old in geriatric services.
