Ticks Feeding on Dog Ear
• Time of attachment: unknown in humans
• Animal models, Borrelia infection occur in <16 hrs
• Spirochetes in tick salivary glands prior to feeding
may cause rapid Borrelia transmission from ticks to
humans, case studies show rapid transmission

• Amoxil 50-100 mg/kg/day
• Rifampin 10 mg/kg/day
Optometrist referral and then:
• Plaquenil 100 mg BID
• Probiotics 2 hours after Antibiotic
46
• accidental double dosing:
Result: 2 days without pain and eye droop
resolved!
• Amoxil increased to 75 mg/kg/day
47
• Decreased severity of pain
• Some days “back to being Donny”
• More good days than bad
• Eye droop the telltale marker!
Risk/benefit analysis: informed decision to
continue antibiotics
48
Happy, sparkling, interactive
Extended family noted dramatic difference
11 days of lid droop gone
Change in location of pain, from feet/toes to
knees
Plan: try Azithromycin/Rifampin/Plaquenil
49
50
Within 2.5 weeks eye droop, leg
pain, crying/tantrums/anger &
bedwetting returned
Response on restarting: partial
? Resistance or tolerance?
Change to Septra/Amoxil/Azithromycin
Naturopath for herbals: BLt tincture
Within 4 weeks dramatic improvement
51
Minor leg pain
Rare day-end lid droop
Scholastically excelling!
Socially excelling!
Elispot 0 on all levels showing no T-immune cell
response to Borrelia
Now: One year later improvement
is sustained
52
Educational Points from this Case:
• Initial MD missed EM (erythema migrans)
• Our tests “failed” without clinical aspect
• Treatment had to be individualized,
flexible and “n of 1 trial”
• Life changing benefits from not giving up

“Daptomycin was the common element in

• Improvement continued for a year
• Wings of study post-IV were single agent oral,
NOT combination therapy used by clinicians

• Diversity of presentation: Great Imitator
• Variable morphologies: spirochete,
round bodies, intracellular
• Biofilms
• Co-infections
• Co-morbidities: impact on
endocrine and immune systems
• Slow reproductive cycle, stationary phases
• Other spirochete models (TB, syphilis)
• Example: latent TB treated with 6-9 months INH or 3-4
months of combinations; ACTIVE TB treated with 4 to
7 months of combinations - PHAC
• Syphilis has 22 functioning genes, the Lyme spirochete
has 132!
• “nearly all recommendations for the treatment of
syphilis are based not only on clinical trials and
observational studies, but many decades of clinical
experience” - CDC.
63
64
Awareness in Action
Education Needs:
1. Higher Level of Suspicion “Great Imitator”
2. Acute phase serology tests NOT helpful!
Clinical diagnosis is key
much more than “the target lesion”

Lyme Treatment
Essential Education
66
Educate: Principles of Treatment LD
1. Individual Patient-centered
2. Challenging: must be an N-of-1 trial
with informed consent of risks and
benefits
3. Possibly complicated by co-infections
67
• Wear hat, long sleeves and pants and
light coloured clothing
• Tuck pant legs into socks
• Use DEET insect repellant
• Check for ticks on body after outside
• Vaccinate pets and monitor for ticks
• Safety Zone of no plants between
forest and property
68
Treat with antibiotics: Doxycycline
100 -200 mg twice daily for 20 days to
prevent chronic disabling Lyme
disease
Doctor will submit the tick to PHL for
testing for Bb
69
• Doctors nervous of “doing the right
thing” because they fear reprisals
• Resulted in fewer doctors treating LD
• Many patients must go to US for
treatment
• Patients are driven underground to try
to find doctors who will treat them to
help them get better
70
Patients’ Perspective: Why are
Canadian patients leaving the
country for treatment?
• US Doctors with Extensive Expertise
• They get better
71
Diagnosis/management of Lyme hampered by:
• Incomplete understanding of Borrelia’s
pathophysiology
• Lack of reliable biomarkers
• Insufficient clinical trial evidence
In the future, successful management will be based
• Identification of actual pathophysiologic
mechanisms
• Methodology for determining which bacteria are
operating in a specific patient
• Targeted therapies, including combinations of
therapeutic modalities
72
• Create LD medical undergraduate curricula
• Accredited online courses from CFPC,
RCPS, CMA and Provincial Colleges
• Create Subspecialty post-graduate training
in tick-borne illness available for physicians
in any field (family practice, rheumatology,
psychiatry, neurology, cardiology, general
internal medicine etc.)
73
Research – better clinical tests based on Borrelia
species (burgdorferi, miyamotoi etc.) pathophysiology
Educate - Doctors about clinical guidelines
- Public about prevention
Support - chronically ill patients
Support - doctors treating LD in Canada
Creation of medical experts in emerging medical field
of tick borne illnesses
Creation of funded National Lyme Network including:
researchers, clinicians and patients to formulate next
steps quickly
74
Cost Effectiveness
Weeks vs. Years Treatment
Ability vs. Chronicity
Australia’s skin cancer prevention slogan: Sid the Seagull
Slip on a shirt, slop on sunscreen, slap on a hat & Stop skin cancer.
75
Cover up from your head to your
feet
Spray with DEET
When ticks eat your meat
Treat
Prevent Lyme Disease!
