Borna virus is an RNA virus that was originally discovered in Germany. It is not known to be tick transmitted but via close person to person contact, via pregnancy, and via blood transfusion.
Borna virus is a brain infection. The good news is that it does not cause permanent damage once eradicated. About 30% of people tested are positive for latent Borna virus. The more stress a person is under, the more likely the virus will be found in an active form.
Testing for Borna virus is only available today in Germany. Since healthy people may test antigen positive, both an antigen positive test and a positive test for circulating immune complexes is needed to suggest illness.
Amantadine is the drug of choice for Borna virus treatment. Dosage is generally started at 200mg per day and may be increased to 400mg per day after checking Amantadine blood levels. 12 weeks of treatment can often inactivate the virus if a patient has a functional immune system; longer or indefinite treatment may be required in those with immune-suppression.
In patients with a presentation of depression or bipolar disorders, Borna virus may be a factor.
Both Dr. Willy Burgdorfer and Dr. Eva Sapi have identified nematodes in ticks. It is thus possible that patients with chronic Lyme may also have nematode (worm) infections.
Dr. Lawrence Klapow has identified a lung worm called Cryptostrongylus pulmoni in up to 75% of patients with CFIDS. These worms may not present with expected high eosinophils or elevated IgE as they suppress the immune system. Fatigue and rashes are common complaints. The worms live primarily in the lungs and can be diagnosed by lung tissue biopsy or via sputum samples.
Another interesting comment that was made was that nematodes are known to contain viruses and we may someday find that viruses such as XMRV and others are within the nematodes that have been identified in ticks. More research is needed.
Dr. B. shared the latest on promising pharmaceutical agents for chronic Lyme disease. The latest is Tigecycline which is a minocycline-like drug only available as an IV.
Intracellular drug levels of many antibiotics are reduced by efflux pumps which often make the intracellular levels of the drug too low to have a beneficial effect. With Tigecycline, the efflux pump is inhibited which increases intracellular concentrations. Nausea can be extreme in some cases. Sun sensitivity is an issue and the drug cannot be given to children or pregnant adults. Dr. B commented that this may be the most effective drug for chronic Lyme disease.
While on Tigecycline, intracellular levels of drugs such as Biaxin, Zithromax, and Ketek may be increased and these may then be more effective.
Acidic environments inactivate antibiotics. Unfortunately, Lyme lives best in acidic areas of the body. It is thus true that it may also be helpful to consider Plaquenil or Amantadine to alkalinize the body as another mechanism for making these antibiotic therapies more beneficial.
In patients with potential infection with Borna virus, Tigecycline plus Amantadine may be a powerful combination.
The discussion on IV led to further talk of Bicillin. At a dose of 1.2 million units 3-4 times a week, this may be as effective as IV therapy. Even at this dose, this is a relatively low dose of antibiotics but the sustained presence of the drug in the body adds to the effectiveness. In some patients, Bicillin is better than IV therapy. Injecting the drug over a 2 minute time period is suggested.
Dr. B has found Bicillin to be useful during pregnancy and with a combination of Bicillin and Zithromax, he has not had any ill babies since he began using this approach in 1991.
Several discussions at the conference suggested that IVIG may be highly beneficial in repairing damage to small nerve fibers. IVIG may be indicated in patients with neuropathies. Skin biopsies are needed to determine if the damage is present. When present, symptoms may include orthostasis (blood pressure related problems), air hunger, and GI problems due to autonomic dysfunction.
IVIG therapy can reverse the small nerve fiber damage and support the process of remyelination. Treatment generally lasts 6-18 months.
With patients that are Borrelia and Bartonella positive with possible Babesia, a cephalosporin plus a fluoroquinolone for 6 weeks to 3 months may be used. Then the doctor may replace the fluoroquinolone with a macrolide and add Mepron if needed. Cephalosporins increase the effect of fluoroquinolones in the treatment of Bartonella.
For very ill patients with Borrelia where Ceftriaxone has failed and the patient has Bartonella (or BLO) and possibly Mycoplasma, Tigecycline plus Amantadine with optionally adding Metronidazole or Tinidazole may be helpful.
Clinical Pearls and Observations
Dr. B. gave the group a number of "Clinical Pearls". He shared the following:
- Taking oral antibiotics and later IV is not as effective as doing IV first and later taking oral antibiotics
- DEET does not work. From work done by Eva Sapi, we must use Permethrin
- Quinine drugs for Babesia treatment seem to make later treatment for Bartonella with quinolones such as Levaquin less effective. When both Bartonella and Babesia are present, he suggests addressing Bartonella first
- Taking artemisinin daily for longer than 3 weeks can render it ineffective. A 2 week on 2 week off cycle may be appropriate
- Electrical shocks may be due to salt imbalances and occur in patients with low MSH and low ADH (anti-diuretic hormone)
- The only way to remove organic toxins from the body is with dry sauna
- NT Factor can make a significant difference in energy and stamina
- Parasites appear to be more common in patients living on the West Coast
- IVIG plays a much bigger role than ever expected
- Ketek is the most effective oral medication for Lyme but it is not without significant risks such as has QT interval impacts and also inhibits CYP3A4. Liver function must be closely monitored
- Flagyl requires a 2 week consistent dosing to be effective. 2 week pulses may be used. Vitamin B may be given to help reduce neuropathies seen with Flagyl administration
- Fluoroquinolone administration can lead to tendonitis. IV or IM magnesium and IV vitamin C may be helpful in reducing complications
- Alinia may be helpful as a Borrelia cyst-buster
Spending time at the ILADS event provides a sense of hope for the future. Brilliant minds are working together and collaborating on how to get patients well. It feels like we are getting closer...
Thanks Dr. B!
