53. Educational Points from this Case:

• Our tests “failed” without clinical aspect
• Treatment had to be individualized,

POOR MIC (minimum inhibitory

• Wings of study post-IV were single agent oral,
NOT combination therapy used by clinicians

• Diversity of presentation: Great Imitator
• Variable morphologies: spirochete,

• Biofilms
• Co-infections
• Co-morbidities: impact on
endocrine and immune systems
63. • 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.

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
67. 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
68. • 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
69. 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
70. • 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
71. Patients’ Perspective: Why are
Canadian patients leaving the
country for treatment?
• US Doctors with Extensive Expertise
• They get better
71
72. 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
73. • 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
74. 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
75. 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
76. Cover up from your head to your
feet
Spray with DEET
When ticks eat your meat
Treat
Prevent Lyme Disease!
