It is estimated that about 1% of the world population suffers from some form of rheumatoid arthritis: a persistent joint inflammation, which eventually destroy them. It is a disease known for centuries; but was not defined as such until 1900 at the hands of French doctor Augustine Jacob Lander-Beauvais such diseases are already named by Hippocrates and Galen. Despite this, today neither be cured nor its causes are known. However, there is news.
What we do know is that, like other devastating diseases such as sclerosis or fibromyalgia, arthritis has an autoimmune origin it is caused by a fault in our immune system, which mistakenly attacks the body’s own cells. In addition, this ruling, as increasingly pointing research, could be caused by a change in our intestinal flora.
A study published in 2013 by Jose Scher, a rheumatologist at the University of New York, showed that people with rheumatoid arthritis were significantly more likely to harbor bacteria in your gut Prevotella copri people who did not suffer from the disease. It could be just a coincidence, but in another study, Scher found that psoriatic arthritis -the joint inflammation caused by psoriasis, another disease had a significantly lower amount of certain intestinal bacteria.
The secret is in our guts
As aiming a revealing article by David Kohn for The Atlantic, Scher investigations are just some of the thousands who suggest that changes our microbiota-that is, the set of microorganisms that normally live in our body- a decisive effect our health. The population of microorganisms that live with us exceeds the number of own cells at a ratio of 10: 1, for every human cell took us 10 microbes.
The population of microorganisms that live with us exceeds the number of own cells at a ratio of 10 to 1: for every human cell took us 10 microbes. These bacteria are spread throughout the body, but are especially numerous in our digestive tract. The intestinal tract is home to thousands of species of bacteria, which together weigh between half a kilo and kilo and a half. It is also in the intestine where they live most of our defenses: at least two thirds of immune cells.
Many of these bacteria perform essential functions for our body (the most) and other impairs their proper functioning (the least). In addition, what seems increasingly clear is that their influence is not limited to the digestive tract: no changes in gut flora that affect our overall health and can lead to diseases that seemingly have nothing to do with what happens in our guts such as arthritis. This is a paradigm shift in The Atlantic. A player who actually is thousands, as many as different bacteria can swarm by our intestine.
Our micro biota has changed significantly in the last century, especially in the last 50 years,” he says in The Atlantic microbiologist at the University of New York Martin Blazer. He believes that the massive use of antibiotics is behind the extinction of numerous microbes previously found naturally in our body. However, drugs are not the only culprits: changes in diet, excessive hygiene and less contact with nature also have their share of blame.
Find the direct relationship between each type of bacteria and every autoimmune disease is a highly complex task. This rapid change is suffering our bacterial ecosystem may be directly related to the increased incidence of autoimmune diseases -and some scientists believe, with obesity.
In particular, has studied the relationship between changes in the micro biota and asthma. The bacterium Helicobacter pylori is present in most of the world’s adults, and the entire population of developing countries, but after analyzing the composition the intestinal flora in a group of American children Blaser found that only 6% had this bacteria. In his opinion, the disappearance of Helicobacter in developed countries is directly related to the overuse of antibiotics, and could be behind the increased incidence of diseases such as asthma, because, according to their studies, their presence reduces immune response body to stimuli air. It is ultimately a carmabola difficult to trace, but potentially fatal.
Find the direct relationship between each type of bacteria and every autoimmune disease is a highly complex task, but the relationship between one thing and another can understand anyone. The bacteria that inhabit our intestines have been developed thanks to that have managed to control the response of our immune system intruders. What is happening? By changing the composition of our micro biota, either because there are different bacteria or because the ratio between them is disproportionate, the immune system gets confused and starts to attack not only bacteria that attacked before, but also the body itself.
Since autoimmune diseases may be caused by changes in, the macrobiotic is logical that readjusting it is possible to find a cure for these diseases. Therefore, it is, but there is still a long way to go. To start, but discover that a bacterium is related to a disease is difficult to speak on this until we know why it is related. Returning to the case of rheumatoid arthritis we know that people who harbor the Prevotella copri are more likely to develop the disease but do not know if it’s because this bacterium over stimulates the immune system just attacking the joints, or because it shifts to other bacteria that are responsible for our defenses are not too aggressive.
