慢性疲劳么？小心病毒感染

Virus Link To Chronic Fatigue Syndrome?
慢性疲劳么？ 可能与病毒感染相关
Study: 80% Of People With CFS Show Evidence Of Stomach Bug, Compared To 20% In General Population
研究表明： 80%患慢性疲劳综合征的人伴有胃肠不适症状，而普通人群中仅有20%人伴有胃肠不适。
A group of viruses known to cause respiratory and gut infections may also be a major trigger for chronic fatigue syndrome, known as CFS.
一组已知导致呼吸及胃肠道感染的病毒可能是主要导致慢性综合征（CFS）的促发剂。
In a newly published study, four out of five CFS patients showed evidence of chronic enterovirus infection in stomach tissue biopsies, compared with just one in five healthy people.
最新发表的研究中， 对慢性疲劳综合征患者进行胃组织活检，其中4/5的患者都有慢性肠病毒感染，而在健康人群中，其仅1/5的人会有被感染的证据。
Enteroviruses are very common, second only to the common cold viruses as the most common viral infections in humans, according to the CDC. Most people who are infected with an enterovirus have no symptoms at all.
根据疾病控制中心的数据，除了感冒病毒（cold viruses）外，肠病毒是第二常见的感染人体的病毒。大多数人感染肠病毒后没有任何症状。
California infectious disease specialist John Chia, M.D., says his findings point to chronic infection with the virus as a possible cause of chronic fatigue syndrome in a large percentage of patients.
加利福尼亚的感染性疾病专家John 医师谈到，在大量病人中，他发现慢性病毒感染可能是慢性疲劳综合征的病因之一。
But a longtime CFS researcher says the complex disorder is not likely to be so easily explained.
但是，长期研究慢性疲劳综合征的学者指出不大可能如此容易的解释这种复杂的紊乱性疾病。
James Jones, M.D., of the CDC’s chronic viral diseases branch, says despite extensive research, no cause-and-effect relationship between an active infectious agent and chronic fatigue syndrome has been established.
疾病控制中心慢性病毒性疾病分部的James Jones医师说道，尽管做了大量的研究，目前没有任何感染性病原体与慢性疲劳综合征建立起因果联系。
“This is an illness with a lot of different origins, and to assume that its cause is due to an infection because the symptoms are similar to an infection is a great leap,” Jones tells WebMD.
Jones对WebMD说：“该病有不同的起源。由于其与感染性疾病症状相似而假设其可能与感染相关使对该病的研究有一个飞跃。
Other Conditions Lead To CFS
导致慢性疲劳综合征的其他情况
In previous research, Chia reported finding evidence of chronic infection in the muscles of CFS patients.
在较早的研究中，Chia报道发现在慢性疲劳综合征患者肌肉中发现慢性感染。
In the new study, he looked for similar evidence in stomach tissue taken from CFS patients who had the diagnostic procedure known as endoscopy, in which a long tube with a camera is inserted via the mouth into the stomach and
biopsies of tissue are taken.
在新的研究中，他从慢性疲劳综合征患者的胃组织中寻找相似的线索。 这些病人均接受了内镜检查，即通过口腔将一根携带照相机的管子插入胃部，并且取出组织活检。
Specimens from 165 CFS patients and 34 people without the disorder were tested, and Chia found evidence of possible chronic infection in 82 percent of the CFS patients and 20 percent of the well patients.
检查了163位CFS患者及34位无紊乱症状的人。Chia发现，数据表明82%的CFS患者可能有慢性感染，而无紊乱者中仅20%有感染迹象。
Though the findings must be verified, Chia says they suggest a strong association between possible chronic infection with enterovirus and chronic fatigue syndrome.
尽管仍需进一步证明该发现，Chia指出这表示慢性疲劳综合征可能与肠病毒慢性感染相关性很大。
“Although finding a chronic infection in the stomach may not directly prove a similar infection in the brain, muscle, or heart, it opens up a new direction in the research for this elusive disease,” he writes in the latest online edition of the Journal of Clinical Pathology.
他在最新的临床病理杂志在线版中写道:“虽然在胃中发现了慢性感染不能直接证明会在脑、肌肉、心脏中存在相似的感染，但是为这种原因不明的疾病提供了新的研究方向。”
Specifically, he says endoscopy could prove to be a relatively simple test to confirm persistence of enterovirus infection in CFS patients, as well as a way of following responses to antiviral treatments.
他特别提到内镜检查能够提供一种相对简单的检测方法证明在CFS患者体内存在持续肠病毒感染，同时其还可以观察抗病毒治疗的效果。
Chronic Fatigue and Immune Disorder Syndrome Association of America president Kimberly McCleary says CFS has turned out to be a much more complex illness than anyone could have predicted.
美国慢性疲劳和免疫紊乱综合征协会主席Kimberly McCleary谈到，CFS成为一种任何人都无法预测的极其复杂的疾病。
“It is unlikely that we are ever going to find just one bug to explain all cases of CFS,” she says.
她说：“我们不大可能通过发现一种病毒就能解释CFS的所有情况。”
She points to recent research from Australia finding that three very different infections result in a CFS-like condition in 12 percent of cases.
她指出据澳大利亚研究者发现，在12%的病理中，3种不同的感染可以导致一种CFS类情况。
“It is quite possible that both an infectious agent and the [body’s] response to that agent act as triggers,” she says.
她说：“也许感染病原体和身体对该病原体的反应都在疾病发生中起作用。”
