University of Michigan school of dentistry discovered a gene therapy that lessens peritonitis. This gene therapy for peritonitis helps to stop autoimmune disease as well!
Excessive amounts of TNF alpha, an immune system signalling molecule, is linked not only to all inflammatory autoimmune disease, increased risk of cancer and heart disease but increased risk of infections.
According to the article below RA patients (likely all inflammatory autoimmune sufferers) have a four time higher risk of peritonitis than people without autoimmune disease.
U of Mich Ann Arbor has come up with an injection of an inactivated virus containing a gene for TNF alpha receptors. These receptors act as sponges to soak up excess TNF alpha.
Apparently we in the autoimmune community lack enough of these receptors. I personally suffer from frequent bacterial infections of the skin, peritonitis of the gums, and bouts of pnuemonia (as well as four skin cancer episodes with three kinds of skin cancer).
The dentists at U of Michigan were just trying to reduce peritonitis a bacteria driven disease of the gums that results in bleeding gums, then receding gums and eventually loss of teeth. Their gene therapy worked perfectly to reduce TNF alpha which reduced inflammation of the gums which reduced the bacteria's ability to infect.
However, a serendipitous side effect of treatment was that in RA patients their RA symptoms were substantially reduced as well. Apparently a high percentage of the patients they tried the gene therapy on had RA. No surprise when researching peritonitis.
The gene therapy treatment apparently consisted of a single shot in the arm. For RA patients a 30% reduction in symptoms. I would take a single shot for a 1% chance.
The improvement in RA patients should come as no surprise because the most effective meds for inflammatory autoimmune disease today soak up TNFalpha. Those meds are Enbrel, Humira, Remicade, and Cimzia.
This research is good news for us looking toward better therapies in the next two but offers no hope now unless maybe you have enough money to buy an endowment at U of Mich Ann Arbor which might get you access OR call you congressional Reps and US senators and ask them to support Abigail Alliance's FULL ACCESS to experimental medication and therapies.

Gene therapy effective treatment against gum disease
ANN ARBOR, Mich.---Scientists at the University of Michigan have shown that gene therapy can be used to successfully stop the development of periodontal disease, the leading cause of tooth loss in adults.
The findings will be published online Dec 11 in advance of print publication in Gene Therapy.
Using gene transfer to treat life threatening conditions is not new, but the U-M group is the first known to use the gene delivery approach to show potential in treating chronic conditions such as periodontal disease, said William Giannobile, professor at the U-M School of Dentistry and principal investigator on the study.
"Gene therapy has not been used in non-life threatening disease. (Periodontal disease) is more disabling than life threatening," said Giannobile, who also directs the Michigan Center for Oral Health Research and has an appointment in the U-M College of Engineering. "This is so important because the next wave of improving medical therapeutics goes beyond saving life, and moves forward to improving the quality of life."
The preclinical study offers was a collaboration with the Seattle-based biotechnology company Targeted Genetics. In July, Targeted Genetics released human trial results that showed the same gene therapy approach used to stop periodontal disease had positive affects in human patients with rheumatoid arthritis, another chronic, non-life threatening, disabling condition. The company tested 127 human subjects and showed a 30 percent improvement in pain relief, and gain of function, among other enhancements using the gene treatment.
People with rheumatoid arthritis are four times more likely to also be afflicted with periodontitis. Periodontal disease is also linked to systemic conditions such as heart disease, bacterial pneumonia and stroke, likely due to the spread of bacteria coming from the oral cavity that invade other parts of the body.
Using gene therapy, Giannobile's group found a way to help certain cells using an inactivated virus to produce more of a naturally-produced molecule soluble TNF receptor. This factor is under-produced in patients with periodontitis. The molecule delivered by gene therapy works like a sponge to sop up excessive levels of tumor necrosis factor, a molecule known to worsen inflammatory bone destruction in patients afflicted with rheumatoid arthritis, joint deterioration and periodontitis.
The gene also delivers quite a bit of genetic bang for the buck. The periodontal tissues were spared from destruction by more than 60-80 percent with the use of gene therapy.
"If you deliver the gene into the target cells once, it keeps producing in the cells for a very long period of time or potentially for the life of the patient," Giannobile said. "This therapy is basically a single administration, but it could have potentially life-long treatment effects in patients who are at risk for severe disease activity."
The next step is additional safety testing on periodontal patients, he said.
The research was funded by the National Institutes of Health. Co-authors included Haim Burstein, a research scientist at Targeted Genetics Corporation, and members of U-M research team Joni Cirelli, Chan Ho Park, Jim Sugai and Katie MacKool.
