CASE STUDY| Your microbiome may be a riskfactor for disease
A number of genes involved in susceptibility to inflammatory bowel disorders (IBDs), including Crohn disease and ulcerative colitis, have been identified. However, it is clear that other risk factors, both genetic and nongenetic, are important in triggering the onset of these diseases. Recent research has centered on understanding the role of the gut microbiome and its interactions with the host genome in IBD. It is known that the microbiome of those with IBD is different from that of those whose IBD is in remission, and it is also different from that of people who do not have IBD. These observations suggest that transfer of microbiota from unaffected individuals via fecal microbial transplantation (FMT) might be a successful treatment for IBD. This idea is supported by the use of FMT as an effective treatment in IBD individuals for a potentially life-threatening infection caused by the bacterium Clostridium difficile. Currently, four clinical trials are underway to evaluate the use of FMT as a treatment for IBD.
If you had IBD, how would you react if your physician recommended that you enroll in one of these clinical studies to evaluate fecal transplants as a treatment?
To review:
As an individual with inflammatory bowel disorder(IBD), how one would react if recommended by a physician to participate in the clinical trial for IBD treatment.
Introduction:
IBD is an inflammatory disorder that has recently been associated with gut microbiome. Several genetic and non-genetic factors have been identified to be associated with IBD. Recent researches have suggested an important role of the microbiome and its interaction with the host genome in IBD patients. Research has supported the evidence that there is a difference in the gut microbiome of individuals with IBD and the ones who do not have. Therefore, transfer of microbiota from unaffected individuals throughfecal microbial transplantation (FMT) might be a successful treatment for IBD. To advocate this hypothesis, four clinical trials are undergoing.
Explanation of Solution
FMT is a therapy to transfer fecal microbiota from unaffected to the affected individual. This therapy has helped in treating a potentially life-threatening infection caused by bacterium Clostridiumdifficile.
Depending on the intensity of the disease, one must see whether it is a better option or not. In case IBD is detected at a very early age, one should not agree to undergo clinical trials. It is better to first been treated with conventional anti-inflammatory drugs. On the other hand, if the disease is chronic and no positive results have been seen with drugs, in such case one can opt to participate in the clinical trial in a hope to get rid of the disorder.
Therefore, it can be concluded that based on the degree of disease and the time period since its onset, it must be decided whether to participate or not in the clinical trials.

- An outbreak of Ebola between 2014 and 2016 resulted in 28,616 cases and 11,310 deaths in Guinea, Liberia and Sierra Leone. An additional 36 cases and 15 deaths were reported outside these 3 countries. This deadly disease urged the need for extensive research on Ebola to better understand and treat the disease and prevent future outbreaks. Ebola is a - SSRNA virus. What does this mean for how it is converted into proteins? Does this virus require additional machinery to be infectious? Can you hypothesize based on how it replicates in the cell what scientists might hope to target for treatment or prevention of Ebola?arrow_forwardIn 2013, there was an outbreak of methicillin-resistant Staphylococcusaureus (MRSA) at an NFL training facility.

A settlement with undisclosed terms was reached in2017. MRSA is highly contagious and is spread by direct skin contactor by airborne transmission and can result in amputation or death.In addition, MRSA is very difficult to treat because it is resistant tomany antibiotics.

Mad-cow disease is caused by a prion, an infectious particle that consists only of protein. In 1986, the media began reporting that cows all over England were dying from a mysterious disease. Initially, there was little interest in determining whether humans could be affected. For 10 years, the British government maintained that this unusual disease could not be transmitted to humans. However, in March 1996, the government did an about-face and announced that bovine spongiform encephalopathy (BSE), commonly known as mad-cow disease, can be transmitted to humans, where it is known as variant Creutzfeldt-Jakob disease (vCJD). As in cows, this disease eats away at the nervous system, destroying the brain and essentially turning it into a spongelike structure filled with holes. Victims experience dementia; confusion; loss of speech, sight, and hearing; convulsions; coma; and finally death. Prion diseases are always fatal, and there is no treatment. Precautionary measures taken in Britain to prevent this disease in humans may have begun too late. Many of the victims contracted it over a decade earlier, when the BSE epidemic began, and the incubation period is long (vCJD has an incubation period of 10 to 40 years). A recent study concluded that 1 in 2,000 people in Great Britain carry the abnormally folded protein that causes vCJD. In spite of these numbers, the death rate from vCJD remains low. It is not clear whether this means that the incubation period for the disease is much longer than previously thought, or whether they may never develop the disease.

- The human intestinal tract is home to a vast, diverse microbial community. The bacteria that comprise this microbial community serve a number of important, beneficial functions. However, some bacterial species have been suggested to play a role in certain forms of cancer. One such bacteria is Fusobacterium nucleatum (i.e., F. nucleatum). Investigators wishing to study the role of F. nucleatum in colorectal cancer developed a new assay for detecting these bacteria in tumor tissue. In controlled experiments, the test was highly sensitive in detecting F. nucleatum and also had high specificity. To examine consistency in their test findings, the investigators also conducted repeat tests in 50 tissue samples. From these repeat tests, the investigators observed that the overall number of samples in which F. nucleatum was detected was almost identical (10 out of 50 on the first test vs. 11 out of 50 on the repeat test); for 9 samples, F. nucleatum was detected on both the initial and the…arrow_forwardThis article highlights a young doctor at Elmhurst Hospital during the beginning of Covid-19 pandemic.
