L'h\u00e9morragie c\u00e9r\u00e9brale peut \u00eatre transmise par transfusion sanguine, sugg\u00e8re une nouvelle \u00e9tude.<\/p>\n

L'angiopathie amylo\u00efde c\u00e9r\u00e9brale, cause d'h\u00e9morragie spontan\u00e9e, pourrait \u00eatre transmise par le don de sang, ont indiqu\u00e9 des chercheurs dans une \u00e9tude. \u00e9tude<\/a>, publi\u00e9 dans Jama Network. Cependant, il est tr\u00e8s peu probable que des personnes souffrent d\u2019une h\u00e9morragie c\u00e9r\u00e9brale r\u00e9sultant directement d\u2019un don de sang.<\/p>\n

La CAA, un type de trouble c\u00e9r\u00e9brovasculaire qui provoque l'accumulation de prot\u00e9ines dans les petits vaisseaux sanguins du cerveau, est la cause fr\u00e9quente de nombreuses h\u00e9morragies c\u00e9r\u00e9brales r\u00e9currentes et spontan\u00e9es.<\/p>\n

L'h\u00e9morragie intrac\u00e9r\u00e9brale spontan\u00e9e est un caillot sanguin qui se d\u00e9veloppe en l'absence de traumatisme ou de chirurgie.<\/p>\n

Des \u00e9tudes ant\u00e9rieures sugg\u00e8rent que le CAA peut \u00eatre transmis par des proc\u00e9dures telles que la neurochirurgie et le traitement \u00e0 l'hormone de croissance.<\/p>\n

Dans la derni\u00e8re \u00e9tude, les chercheurs ont examin\u00e9 les donn\u00e9es de plus d'un million de patients provenant d'une base de donn\u00e9es su\u00e9do-danoise sur les transfusions, qui contient des enregistrements de donneurs de sang et de patients ayant re\u00e7u des transfusions sanguines depuis les ann\u00e9es 1970.<\/p>\n

\u00ab Dans cette \u00e9tude de cohorte exploratoire r\u00e9trospective, qui a inclus 759\u00a0858 patients en Su\u00e8de et 329\u00a0512 patients au Danemark, la r\u00e9ception de transfusions de globules rouges provenant de donneurs ayant d\u00e9velopp\u00e9 par la suite de multiples h\u00e9morragies intrac\u00e9r\u00e9brales spontan\u00e9es \u00e9tait significativement associ\u00e9e \u00e0 un risque accru de d\u00e9velopper une h\u00e9morragie intrac\u00e9r\u00e9brale spontan\u00e9e par rapport \u00e0 la r\u00e9ception d'une h\u00e9morragie intrac\u00e9r\u00e9brale spontan\u00e9e. transfusion de donneurs sans h\u00e9morragie intrac\u00e9r\u00e9brale ult\u00e9rieure \u00bb, ont \u00e9crit les chercheurs.<\/p>\n

L\u2019\u00e9tude a montr\u00e9 que seulement 0,11 TP3T des donneurs ont ensuite souffert d\u2019h\u00e9morragies c\u00e9r\u00e9brales r\u00e9currentes.<\/p>\n

\u00ab Les transfusions sanguines sont relativement courantes, ce qui fait de leurs \u00e9ventuels effets n\u00e9gatifs un probl\u00e8me de sant\u00e9 publique important. Cependant, dans ce cas, il est tr\u00e8s peu probable que vous souffriez d'une h\u00e9morragie c\u00e9r\u00e9brale due \u00e0 quelque chose de transmis par transfusion", a d\u00e9clar\u00e9 le dernier auteur de l'\u00e9tude, Gustaf Edgren, dans un communiqu\u00e9 de presse.<\/p>\n

Les chercheurs ont \u00e9galement d\u00e9couvert que les patients souffrant d'h\u00e9morragies c\u00e9r\u00e9brales r\u00e9currentes apr\u00e8s avoir re\u00e7u du sang de donneurs ayant h\u00e9morragies c\u00e9r\u00e9brales<\/a> \u00e9taient plus de deux fois plus susceptibles de souffrir eux-m\u00eames d\u2019une h\u00e9morragie c\u00e9r\u00e9brale.<\/p>\n

Pour confirmer davantage les r\u00e9sultats et identifier les prot\u00e9ines aberrantes associ\u00e9es au CAA, l\u2019\u00e9quipe de recherche pr\u00e9voit d\u2019\u00e9valuer les \u00e9chantillons de la biobanque danoise de l\u2019\u00e9tude sur les donneurs de sang.<\/p>\n

\u00ab Cette \u00e9tude ne d\u00e9montre pas de causalit\u00e9, donc l\u2019augmentation du risque observ\u00e9e pourrait d\u00e9pendre d\u2019autres facteurs.

However, it is highly unlikely that people would suffer a brain hemorrhage as a direct result of receiving donated blood.CAA, a type of cerebrovascular disorder that causes the piling up of proteins in the small blood vessels within the brain, is the common cause of many recurring and spontaneous brain hemorrhages.Spontaneous intracerebral hemorrhage is a blood clot that develops in the absence of trauma or surgery.Previous studies suggest that CAA can be transmitted through procedures like neurosurgery and growth hormone treatment.In the latest study, researchers looked into data from more than a million patients from a Swedish-Danish transfusion database, which holds records of blood donors and patients who had blood transfusions since the 1970s.\"In this exploratory retrospective cohort study, which included 759,858 patients in Sweden and 329,512 patients in Denmark, receiving red blood cell transfusions from donors who later developed multiple spontaneous intracerebral hemorrhages was significantly associated with an increased risk of developing spontaneous intracerebral hemorrhage compared with receiving a transfusion from donors without subsequent intracerebral hemorrhage,\" the researchers wrote.The study showed that only 0.1% of the donors subsequently suffered recurring brain hemorrhages.\"Blood transfusions are relatively common, which makes possible negative effects an important public health issue. However, in this case, it's very unlikely that you'd suffer a brain hemorrhage from something transmitted through a transfusion,\" the study's last author Gustaf Edgren said in a news release.The researchers also found that patients who suffered recurring brain hemorrhages after receiving blood from donors who had brain hemorrhages were more than twice as likely to suffer brain bleeding themselves.To further confirm the findings and to identify aberrant proteins associated with CAA, the research team plans to evaluate the samples from the Danish Blood Donor Study biobank.\"This study does not demonstrate causality, so the observed increase in risk could depend on other factors. More research is needed to confirm our findings and understand the potential underlying mechanism,\" said Jingcheng Zhao, the first author of the study.Researchers hope the study adds to the evidence that CAA can be transmitted between individuals, a finding that has consequences in several fields.Published by Medicaldaily.com","og_url":"https:\/\/urbancare.clinic\/fr\/lhemorragie-cerebrale-se-transmet-elle-par-les-transfusions-sanguines-une-etude-indique-quil-existe-un-leger-risque\/","og_site_name":"Urban Care Clinic","article_publisher":"https:\/\/www.facebook.com\/urbancarezanzibar","article_published_time":"2023-09-15T07:29:04+00:00","og_image":[{"url":"https:\/\/urbancare.clinic\/wp-content\/uploads\/2023\/09\/does-brain-hemorrhage-transmit-through-blood-transfusions-study-says-there-is-a-slight-chance.jpg","type":"","width":"","height":""}],"author":"Urban Care Clinic","twitter_card":"summary_large_image","twitter_image":"https:\/\/urbancare.clinic\/wp-content\/uploads\/2023\/09\/does-brain-hemorrhage-transmit-through-blood-transfusions-study-says-there-is-a-slight-chance.jpg","twitter_misc":{"\u00c9crit par":"Urban Care Clinic","Dur\u00e9e de lecture estim\u00e9e":"2 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/urbancare.clinic\/does-brain-hemorrhage-transmit-through-blood-transfusions-study-says-there-is-a-slight-chance\/#article","isPartOf":{"@id":"https:\/\/urbancare.clinic\/does-brain-hemorrhage-transmit-through-blood-transfusions-study-says-there-is-a-slight-chance\/"},"author":{"name":"Urban Care Clinic","@id":"https:\/\/urbancare.clinic\/#\/schema\/person\/f286c4d84be896d302aceda3ed7e789c"},"headline":"Does Brain Hemorrhage Transmit Through Blood Transfusions?
