Lyme Disease Protocols
CHARACTERISTICS of BORRELIA BURGDORFERI
- Over 1500 gene sequences
- At least 132 functioning genes (in contrast, T. pallidum has 22 functioning genes)
- 21 plasmids (three times more than any known bacteria)
IMMUNE EVASION (‘STEALTH’ PATHOLOGY)
- Immune suppression
- Phase & antigenic Variation
- Physical seclusion
- Secreted factors
TYPES OF LYME DISEASE
- Early Lyme Disease (“Stage I”)
- At or before the onset of symptoms
- Can be cured if treated properly
- Disseminated Lyme (“Stage II”)
- Multiple major body systems affected
- More difficult to treat
- Chronic Lyme Disease (“Stage III”)
- Ill for one or more years
- Serologic tests less reliable (seronegative)
- Treatment must be more aggressive and of longer duration
CHRONIC LYME
- Disease changes character
- Involves immune suppression
- Less likely to be sero-positive for Lyme
- Development of alternate forms of Borrelia
- More likely to be co-infected
- Immune suppression and evasion
- More difficult to treat
- Protective niches
ALTERNATE MORPHOLOGIC FORMS
- Spirochete form- has a cell wall
- L-form (spiroplast)- no cell wall
- Cystic form
IMMUNE SUPPRESSION BY Borrelia burgdorferi
- Bb demonstrated to invade, inhibit and kill cells of the immune system
- The longer the infection is present, the greater the effect
- The more spirochetes that are present, the greater the effect
PROTECTIVE NICHES
- Within cells
- Within ligaments and tendons
- Central nervous system
- Eye
DIAGNOSING LYME
- It is a clinical diagnosis supported by appropriate testing (likelihood of a false negative must be understood)
- Look for multi-system involvement
- 17% recall a bite; 36% recall a rash
- 55% with chronic Lyme are sero-negative
- PCRs- 30% sensitivity at best- requires multiple samples, multiple sources
NATURAL KILLER CELL ACTIVITY AND NUMBER
- Low counts seen in active Lyme
- Reflects degree of infection
- Can be used as a screening test
- Can be used to track treatment response
- Can predict relapse
ELISA ANTIBODY TESTING
- Over 75% of patients with chronic Lyme are negative by ELISA
WESTERN BLOT
- Reflects antibody response to specific Bb antigens
- Different sensitivities and specificities of the bands
- Some bands are potentially seen in different bacteria- “nonspecific bands”
- Some bands are specific to spirochetes
- Some bands are specific to Bb
- Specific: 18, 23-25, 28, 31, 34, 37, 39, 58, 83 & 93
- Spirochetes in general: 41 (flagellum)
- First immune response if present is usually 41 and 23 KD bands
- Response to the 31 KD proteins is not usually seen for a year after initial infection
CDC IGG WB CRITERIA
- IGG WB 5 of the 10 bands (18, 23, 28, 30, 39, 41, 45, 58, 66)
- Criteria based on Early Lyme
- IGENEX adds 3 specific bands (31, 83 and 34) and 3 non-specific bands (22, 37, 73)
CDC IGM WB CRITERIA
- IGM WB 2 of the 3 bands 23, 39, 41
- IGENEX adds 3 specific bands (31, 34 and 83) and 3 non-specific bands (22, 37, 73)
REVISED CRITERIA WITH QUEST WB
- IGG WB: 2 specific band criteria have demonstrated improved sensitivity and maintained specificity
- Can diagnose Lyme if any one band (IgG or IgM) of 18, 23, 28, 39 or 58 kDa or if any 2 or more of the following bands are present: 30, 45, 41 and 93
- If negative or require further confirmation, can obtain IGENEX WB (adds specific bands of 31, 34 an 83, which are typically seen in chronic disease)
- Positive if any one band of 18, 23, 28, 31, 34, 39, 58 or 83
- If positive for Borellia on any test, test for neurotoxins.
- Consider testing for co-infections (discussed below)
- Check for coagulation defect
LYME DISEASE TREATMENT
- Use an integrative treatment for optimal results. Treating with just antibiotics has poor likelihood for success with chronic Lyme.
- Extended duration often needed for chronic lyme.
- Use clinical endpoints.
- Watch for Herxheimer reactions (may occur in 3-4 week cycles)
- Directed neutraceutical can be beneficial
- Immune Modulators
- Antibiotics
- Oral
- Intramuscular
- Intravenous
- Often need antibiotic combinations with lysomotropics in addition to integrative approach to address different forms (spirochete, L-form, cystic)
- Intravenous Antimicrobial IV’s (Viral Plus, etc) or IV Immunoglobulin
- Adjunctive medications (Lysosomotropics) to increase antibiotic effectiveness
NUTRACEUTICAL
- Samento
- Cumanda
- Fibrinolytic enzymes
- Give probiotics and natural antifungals when using prolonged antibiotics
IMMUNMODULATION
- Essential to improve immune function
- Proboost
- Maitake Mushroom
- Transfer Factor-Lyme specific
- Low Dose Naltrexone 3.5 mg qhs
ORAL ANTIBIOTICS
- Tetracyclines-Doxycycline, Minocycline or Tetracycline
- Good Tissue penetration
- Covers Borrelia and Ehrlichia
- Anti-inflamatory properties
- Photosensitivity, GI upset frequent
- Penicillins such as Augmentin or Amoxicillin
- Addition of Probenecid 500 mg/qd-tid
- Macrolides such as Zithromax, Biaxin
- Combination therapy often needed (ie plus cephalosporin or Flagyl)
- Well tolerated
- Improved tissue penetration with hydroxycholoroquine or amantadine
- Cephlosporins (3rd generation) Omnicef or (2nd generation) Ceftin
- Flagyl or tinidizole
- Kills spore forms of Borrelia
- May decrease effect of tetracyclines
- Antabuse reaction with alcohol
- Potentially neurotoxic
- Adults only
- Rifampin
IM ANTIBIOTICS
- Benzathine Pennicillin
- Excellent foundation for combination treatment
- No GI Side effects
- Efficacy may be close to IV
IV ANTIBIOTICS
- Consider if illness for greater than year
- Failure or intolerance of oral therapy
- Consider starting with IV antibiotics for 1- 3 months (until clearly improved) then oral/IM maintenance
- May require extended duration with long term disease and immune supression
- Ceftriaxone (Rocephin) most commonly used
- Risk of billiary slugging-use Actigall
- Monitor LFT’s
- Cefotaxime (Claforan)
- Monitor LFT’s
- Doxycycline
- Requires central line
- Do not use in pregnancy or children
- Azithromycin
- Requires central line
- Limited experience
- Unasyn
- Primaxin
CO-INFECTIONS IN LYME
- Very common and nearly universal in chronic Lyme
- Diagnostic tests even less reliable
- Co-infected patients more ill
- Co-infected patients more difficult to treat
POSSIBLE CO-INFECTIONS
- Babesia
- Bartonella
- Ehrlichia
- Mycoplasma
- Viruses such as EBV, CMV, HHV6, HHV7
- Others
TESTING
- Antibody testing has a high rate of false-negative
- Consider treatment if poor response despite negative test results
BABESIA
- Is a parasite (one study showed 66% of chronic Lyme have Babesia co-infection)
- Many different species found in ticks (13+)
- Not able to test for all varieties
- Diagnostic tests insensitive
- Chronic persistent infection documented
- Infection is immunosuppressive
TREATING BABESIOSIS
- Can be treated while on Lyme medications
- Lariam
- Atovaquone (Mepron) plus azithromycin
- Consider Flagyl or tinidiazole
- Artemesinin demonstrated to be beneficial
BARTONELLA
- More ticks in NE contain Bartonella than contain Lyme
- Clinically seems to be a different species than “cat scratch disease”
- Gastritis and rashes, CNS, seizures, tender skin nodules and sore soles
- Tests are insensitive
TREATING BARTONELLA
- Levaquin
- Cipro
- Doxy
- Zithromax
EHRLICHIA
- Flu-like symptoms of severe headaches, very painful muscles, low WBC counts or elevated liver enzymes
- Testing insensitive
TREATMENT OF EHRLICHIA
- Doxy
- Rifampin
ADJUNCTIAL MEDICATIONS TO INCREASE ANTIBIOTIC EFFECTIVENESS
- (Lysosomotropics) Will increase the effectiveness of antibiotics and improve success
- Porbenecid Decreases B-lactam excretion and used to achieve higher serum levels.
- Will also decrease excretion on NSAIDS, benzodiazepines and other medications
- Porbenecid Decreases B-lactam excretion and used to achieve higher serum levels.
- Hydoxychloroquine – decreases formation of cystic forms and increases penetration of antibiotics into cysts
- Amantadine – Increases penetration into cells and cysts, immune boosting and is antiviral
