Hope in Lyme disease battle

New bill would protect physicians who prescribe long-term therapy

St. PAUL — Those who suffer chronic, debilitating Lyme disease have only a handful of doctors, maybe three in the state, willing to treat them.

There are probably more, but those physicians are forced to fly under the radar when it comes to aggressive treatment for the tick-bite malady.

Legislation introduced at the Capitol recently by Sen. John Marty, DFL-Roseville, and Sen. Ray Vandeveer, R-Forest Lake, hopes to change that.

Senate Bill No. 1631 allows a doctor to treat chronic Lyme disease without fear of disciplinary action by the state Board of Medical Practice. The legislation is based on a Connecticut law allowing physicians to use their best clinical judgment when treating Lyme disease.

Three states, Connecticut, Rhode Island and California, have passed similar bills to protect physicians.

Marty, who is chair of the Senate health committee, acknowledged a lack of consensus on Lyme treatment in a statement released last month. Even doctors in other states feel they will face severe repercussions for treating patients, he said after a lawmaker’s meeting with state and national Lyme health experts.

One of those experts was Dr. Betty Maloney, a family practice physician from the Forest Lake area who advocates for the Minnesota Lyme Action Support Group.

“It is a principle of medical ethics that patients hear treatment options, including risks and benefits of alternative treatments to make a choice,” Maloney told the Press. “Now patients with persistent Lyme disease hear only strategies advanced by the Infectious Diseases Society of America (IDSA). They don’t learn the alternatives – longer antibiotic therapy or combinations of antibiotics – to make an informed choice.”

Marty and Vandeveer’s bill would make it possible for physicians to prolong administration of antibiotics longer than the recommended 28-day treatment course by removing concerns about medical board interference, noted Maloney. She attended a July IDSA hearing in Washington, DC, to discuss current guidelines for treating Lyme disease, submitting more than 80 pages of research analyses on behalf of the International Lyme & Associated Diseases Society. The 2006 IDSA guidelines state there is no evidence long-term antibiotics cure chronic Lyme.

The issue is complicated because the disease is complicated, Maloney said. “I am not trying to promote a particular agenda beyond wanting patients to get the care they need. I want the science to speak. In some instances, we have lost track of the science and become political on this issue. I’m not sure why it’s political, but if the disease is defined in very narrow fashion, insurance companies have the right to deny care.”

A medical ethicist was asked to submit guidelines for selecting review panel members, according to Maloney. Anyone who made $10,000 related to care and treatment of Lyme patients was omitted from the panel. “Essentially all physicians who treat Lyme were eliminated,” Maloney pointed out. “That was ludicrous. So no one on the panel really understands nuances of treating a Lyme disease patient; who understands the importance of treating co-infecting organisms. The panel doesn’t understand the level of fatigue in Lyme patients and how sick they are — fatigue like ‘I can’t get out of bed.’ Lyme patients aren’t working. They have cognitive issues. The spectrum is wide.”

After review of written submissions and hearing transcripts, the IDSA panel is expected to make a decision on whether guidelines need revision by the end of year.

Meanwhile Lyme disease cases are dramatically increasing in Minnesota, which is considered a hot spot for tick-borne illness. Anoka, Washington and Chisago County are all included on maps of high-risk areas for tickborne disease.

According to Maloney, tick numbers change season to season and by zip code. Pockets of infection have to do with trees, especially oak trees, which attract rodents.

The primary host for the blacklegged, or deer, tick is not deer, but mice. The first stage of its life cycle, the larvae, becomes infected with the bacteria responsible for Lyme disease, Borrelia burgdorferi, after feeding on diseased mice. The next stage is the poppy-seed-sized nymph, the stage that causes the most human cases. Nymphs live in leaf litter under oak trees. Woodpiles are another source of infestation because mice nest there.

Left untreated, Lyme disease can cause a multitude of problems, including paralysis, arthritis, flu-like illness, irregular heartbeat, and loss of ability to concentrate, according to the Minnesota Department of Health. It can infect any organ, including the brain, heart, joints and nervous system. It has also been called the “Great Imitator” because it can look like other diseases. Many sufferers have been misdiagnosed with conditions such as fibromyalgia or chronic fatigue. If the brain is infected, the misdiagnosis might be MS, ALS or Parkinson’s.

If the Marty/Vandeveer legislation passes, will doctors who treat Lyme be confident they won’t be investigated? “Employers might still mandate how physicians treat Lyme, but it is one more obstacle to access removed,” replied Maloney. “I want physicians and patients to go back to relationships. The bill helps that. It allows physicians to more fully enter into a relationship with Lyme patients.”

BBK07, a dominant in vivo antigen of Borrelia burgdorferi, is a poteantial marker for serodiagnosis of Lyme disease.

One of the recently identified Borrelia burgdorferi immunogens, BBK07, is characterized for its expression in the spirochete infection cycle and evaluated for its potential use as a serodiagostic marker for Lyme Disease. We show that bbk07 is expressed at extremely low levels in vitro and in ticks, but is dramatically induced by spirochetes once introduced into the host, and is highly expressed throughout mammalian infection. In contrast, the expression of bbk12, a paralog of bbk07 with 87% amino acid identity, although expressed in vitro, remained undetectable in vivo throughout murine infection and in ticks. BBK07 is localized in the outer membrane and the amino-terminal domain of the antigen is exposed on the microbial surface. A truncated BBK07 protein representing the amino-terminal domain is able to effectively detect antibodies to B. burgdorferi, both in experimentally infected mice and in humans. Further characterization of the immunodominant antigens of B. burgdorferi, such as BBK07, could contribute to the development of novel serodiagnostic markers for detection of Lyme disease.

Lyme disease patients rally for better diagnostic tests

Canadian Lyme disease patients are calling for better doctor training and more accurate tests so sufferers can be diagnosed and treated quickly before their side effects become crippling and chronic.

At rallies across Canada this week, patients called for greater awareness of the disease within the medical community, and asked provincial governments to train doctors to recognize the disease.

“We have people on crutches, we have people that couldn’t come today because they are bedridden,” Lyme disease patient Gwen Barlee told CTV News at a rally in Vancouver. “Most people I know who have Lyme disease don’t have jobs anymore.”

More than 20,000 cases of Lyme disease are diagnosed across North America every year.

The disease is contracted through the bite of an infected tick. Bacteria from the bite enter the bloodstream and can infect joints, the heart and even the brain.

Some experts believe that thousands more suffer for years without an accurate diagnosis. They say blood tests used in Canada are not as sophisticated as those used in the United States, and that few doctors are trained to recognize the symptoms.

Lyme disease can be cured early with antibiotics. However, it can lead to a lifetime of pain, disability and neurological problems if left untreated.

“Our treatment is very expensive, very prolonged and our prognosis is now uncertain,” said patient Rob Manten at a rally in Ontario. “I want to see things changed and I call on our government to assist us in making that happen.”

Their message echoed that of experts published in the Canadian Medical Association Journal earlier this year.

In their report, researchers said Lyme disease, which was largely unheard of in the 1980s, is now found across the country.

The tick that carries the Lyme-causing bacteria Ixodes scapularis is found in Nova Scotia, New Brunswick, southern Quebec, southern Ontario and southeastern Manitoba.

The tick that spreads the bacterium in the West, Ixodes pacificus, is now widespread in southern British Columbia.

The researchers called for better surveillance measures for ticks as they spread throughout Canada. They also called on public health officials to better inform the public and doctors about local risk levels, prevention and the need for early diagnosis.

“Current passive surveillance for tick vectors has identified new endemic areas, but additional methods are needed to precisely identify where Lyme disease is emerging in Canada,” they wrote.

Toll‐Like Receptors 1 and 2 Heterodimers Alter Borrelia burgdorferi Gene Expression in Mice and Ticks

Filed under: Lyme Disease, Lyme Disease News — Tags: , , , , — joethetick @ 5:36 pm

The Journal of Infectious Diseases, Volume 0, Issue 0, Page 000, Latest Articles.

Borrelia burgdorferi, the agent of Lyme Disease, is recognized by Toll‐like receptor (TLR) 1 and 2 heterodimers. Microarray analysis of in vivo B. burgdorferi gene expression in murine skin showed that several genes were altered in TLR1/2‐deficient animals compared with wild‐type mice. For example, expression of bbe21 (a gene involved in B. burgdorferi lp25 plasmid maintenance) and bb0665 (a gene encoding a glycosyl transferase) were higher in TLR1/2‐deficient mice than in control animals. In contrast, messenger RNA levels for bb0731 (a spoJ‐like gene) and bba74 (a gene encoding a periplasmic protein) were lower in TLR1/2‐deficient mice than in wild‐type animals. The expression profiles of…

Researchers To Probe Whether Lyme Disease Will Follow Spread Of Ticks Across U.S.

Filed under: Lyme Disease News — Tags: , , — joethetick @ 10:59 am

Potentially debilitating Lyme Disease doesn’t afflict people everywhere that the ticks harboring it are found. At least not yet. A five-university consortium wants to find out why. These ticks are on the move. As ticks expand into new areas, more people will likely become infected, said Michigan State University fisheries and wildlife assistant professor Jean Tsao.

Tick Saliva May Cure Skin, Liver and Pancreas Cancer

Useful Little Blood Suckers?

It goes to show that you never know where science is going to make its next discovery. Brazilian researchers were studying the repulsive (to me anyway — maybe some of you think they’re cuddly) Amblyomma cajennense tick and discovered an interesting protein in its spit. After some testing on rats with tumors, it looks like tick saliva might hold the key to cure cancers of the skin, liver and pancreas. More details below.

How Does it Work?

According to AFP, the Factor X active protein in the tick spit “shares some characteristics with a common anti-coagulant called TFPI (Tissue Factor Pathway Inhibitor), specifically a Kunitz-type inhibitor which also has been shown to interfere with cell growth.” Since a cancer is basically a group of cells that are growing out of control, controlling this growth is very important.

So the protein was tested on cultures of cancerous cells and “exceeded all expectations.” It didn’t kill normal cells, just those with cancer!

The next step was testing on rats:

“If I treat every day for 14 days an animal’s tumor, a small tumor, this tumor doesn’t develop — it even regresses. The tumor mass shrinks. If I treat for 42 days, you totally eliminate the tumor,” the scientist said.

Don’t Uncork the Champagne Yet

But of course, these results are still just phase 1. the scientists might yet hit speed bumps, or even walls, and not be able to turn this into a cancer treatment. And even if everything works fine, it could take a few years before a drug is made.

But it’s very promising, and goes to show that we still have much to learn from nature and that when we destroy it, we could be losing things like… tick spit.

Insect Repellants Dangerous?

Annoying mosquitoes can ruin your evening around the campfire, but the painful aftermath of a bite can be hazardous, as more diseases are spread by mosquitoes than any other insect or animal.

Lyme disease, transmitted by ticks, has been detected in 49 states, and some parts of the Southeast are suffering from an epidemic of mosquito-borne encephalitis. Fear and warnings about West Nile virus and other insect-transmitted disease have driven sales of repellents up by 36 percent over the past two years. Recent studies, however, are suggesting that some of our favorite products carry dangers of their own.

There are two classes of insect repellents: natural and chemical. Chemical repellents typically use DEET (diethyl-meta-toluamide), while the active ingredients in natural products often include essential plant oils.

If you use a bug repellent that contains DEET:

–Choose products containing less than 20 percent DEET and use them sparingly. Apply just enough to cover exposed skin and/or clothing.

–Do not apply DEET containing products over cuts, wounds, or irritated skin.

–Do not spray in enclosed areas.

–Avoid DEET if you’re taking any medication (including antihistamines). Combined exposure of DEET with other chemicals or drugs is more dangerous than DEET alone.

–After returning indoors, wash treated skin with soap and water.

–Never use insect repellent containing DEET on infants, and use caution with children. A developing nervous system is more susceptible to damage caused by chemicals.

Natural bug repellents are gaining popularity as reports accumulate about the dangers of chemical repellents. Natural formulations use mainly essential plant oils to battle insects.

MAKE YOUR OWN BUG SPRAY

You can make your own bug spray by mixing together a carrier oil with any essential oils in a 10:1 ratio in a 4 oz. spray bottle. Shake well before each use. Refrigerate for up to a week. Be sure to test on a small area before using. Add a few drops of your home-made solution to your shampoo or liquid soap for added protection.

Essential oils are not to be used internally! If using for the first time, test the oil or oil blend on a small patch of skin before applying.

JUST SAY NO TO BUGS

Mosquitoes are attracted to heat, light, and two chemicals produced by humans-carbon dioxide and lactic acid. Mosquitoes breed in standing water and tend to remain close to their birthplace. To repel mosquitoes, make your yard a hard place for mosquitoes to thrive.

Tie a sheet of dryer sheets through a belt loop when outdoors during mosquito season. Get rid of standing water around and outside of the house. Turn over plastic wading pools or wheelbarrows when not in use, and do not allow water to stagnate in birdbaths. Clean out clogged roof gutters. Avoid the outdoors at dusk, in the early evening or at dawn when mosquitoes are heaviest. If you are outdoors during those times, wear long-sleeved shirts, long pants, and socks.

Don’t let bug bites stop you from the great outdoors, but remember to use common sense when applying any type of insect repellent.

Actress Parker Posey Diagnosed with Lyme Disease

Parker Posey

Parker Posey

40-year-old Actress Parker Posey pulled out of an off-Broadway play, called “This,” to focus on battling her tick-borne illness.

Lyme Disease is easily treatable with a short course of antibiotics if diagnosed during it’s early-stage of infection, as it has been for Posey. If left untreated, the Borrelia bacteria can lead to severe heart, neurological and mental problems.

Producers of “This” plan to go ahead with the play in November, but have yet to name Posey’s replacement.

Parker Posey, had been planning to play a single-mom poet dealing with life and love in Melissa James Gibson’s This at the Mainstage Theater. Previews start Nov. 6 and, according to the production’s artistic director, they will kick off as scheduled with a replacement to be announced later.
