Patients with Covid-19 exhibit different immunological profiles according to their clinical presentation 2020-09-28 .txt text/plain 2385 132 45 Conclusions In a population of elderly patients recently infected with Covid-19, CD10 + B cell levels were inversely correlated with clinical severity. However, clinical expression of Covid-19 is extremely variable, with, in some cases, asymptomatic or mild forms [15] , while in other subjects severe forms culminating in acute respiratory distress syndrome (ARDS) have been described, requiring patients to be transferred to Intensive Care Units. The aim of this study was to retrospectively analyze the immunological profile of patients at early stages of Covid-19 in order to identify potential risk factors for subsequent clinical deterioration. We conducted an observational, retrospective cohort study on patients admitted to the Internal Medicine and Infectious Diseases Department in Cannes General Hospital, from March to May 2020, with confirmed Covid-19 infection. In a population of elderly patients at a very early stage of Covid-19, we found that levels of CD10+ B lymphocyte cells were predictive of the clinical severity. ./cache/cord-326881-3j2e92dj.txt ./txt/cord-326881-3j2e92dj.txt
