CMAJ: new discovery! Decreased lymphocyte levels may increase the risk of all-cause death!

January 16, 2020 / BIOON / -- recently, a report was published in the Canadian Medical Association Journal In the previous study, scientists from Copenhagen University found that low levels of lymphocytes, or lymphadenia, may be an early warning of future diseases, and that low lymph counts are associated with a 60% increase in the risk of all-cause mortality Image source: Simon learning researcher Stig According to Dr Bojesen, our research shows that the risk of all-cause death in patients with lymphocytopenia will increase, which has nothing to do with other risk factors leading to all-cause death, such as age and other factors; through routine blood testing, we can find that lymphocytopenia, because the value of lymphocytopenia as an indicator of the future health of the body is not clear, usually patients will not be asked Please check further In this study, the researchers analyzed 108135 participants aged 20-100 who were recruited into the general population research program of Copenhagen from 2003 to 2015 The results showed that the low level of lymphocyte count was related to an increase of 1.6 times of the risk of all-cause death, and the low level of lymphocyte was also related to cancer, cardiovascular disease, respiratory disease and susceptibility Infection was associated with an increased risk of death from other causes (1.5-2.8 times), with 10372 participants dying during the study period The researchers said that the increase of age is directly related to the decrease of lymphocyte count, and the relationship between lymphocyte and death or the decrease of immune ability of the body leads to a variety of potentially fatal diseases; at the same time, the decrease of lymphocyte also means the decline of the body, leading to diseases and deaths The researchers hope that the results of this study may help clinicians to identify high-risk groups; using the absolute risk of all-cause mortality for 2 years, researchers can identify people at risk of lymphocytopenia, such as smokers over 80 years old, who may benefit from additional monitoring, although the benefits of such additional monitoring are still uncertain In the later stage, researchers will further study and clarify this Original source: Marie warny, Jens helby, B ø rge gr ø NNE nordestgaard, et al Accidental limphopnia and mortarity: a prospective court study, CMAJ (2020) doi: 10.1503/cmaj.191024
