Lyme Life Cycle

• Lyme disease is caused by a tick-borne spirochete, Borrelia burgdorferi.• Humans are an incidental host• The lifecycle of the spirochete is predominantly

between mice, deer and the deer tick. In CA ixodes pacificus is the vector and in the east coast it is ixodes scapularis• The nymph deer tick is the most likely to transmit

Lyme, and they are generally feeding in the spring and summer, adults feed in the fall

A closer look• Borrelia burgdorferi is found in NA. But also B

miyamotoi• Borrelia garinii and afzelii are found in Europe. Or

American patients returned from Europe.• Ticks are not the only way to get Lyme: sexual

and placental transmission

Early signs and symptoms of Lyme• Erythema Migrans onset 7-14 days after bite• Sore throat, myalgias, arthralgias, fever, chills,

and headache within days to 2 weeks after infection• If symptoms are severe and high fever is present

consider co-infection with human granulocytic anaplasmosis(HGA) and Babesia.• Babesia microti/duncani in the East and babesia

duncani in CA

Early disseminated Lyme

• Arthralgias, • Neurologic symptoms, headaches, cranial

neuropathy, diffuse or focal mononeuropathy multiplex, lymphocytic meningitis, plexopathy,• Radiculoneuropathy (Bannwarth syndrome)• Cardiac symptoms syncope, dyspnea, chest pain,

palpitations, A-V block• Skin involvement-secondary erythema migrans,

acrodermatitis chronicum atrophicans

Late Lyme disease

•Occurs months to years after infection and often a period of latency• Joint and neurologic symptoms most common• Sub acute encephalopathies, axonal

neuropathies and peripheral neuropathy• Bannwarth syndrome • Neuropsychiatric symptoms

IDSA Treatment of early Lyme disease without significant neurological or

cardiac symptoms

• Doxycycline 200mg bid• Amoxicillin 500mg tid • Cefuroxime 500mg bid• All the above are given for 14-21 days

Page 16: The Lyme Enigma Complexity and Controversy. Lyme Life Cycle Lyme disease is caused by a tick-borne spirochete, Borrelia burgdorferi. Humans are an incidental

ILADS treatment of Erythema Migrans without other symptoms

• Doxycycline 100mg qid or 200mg bid with food• Cefuroxime 1g bid• Amoxicillin 1g tid with probenicid 500mg tid if

pregnant dose Amoxicillin q6h• Treat for 21 days • If pregnant treat for 6 weeks and test for Babesia,

HGA, and Bartonella

IDSA treatment of Lyme carditis

• Ceftriaxone 2gm qd for 10-28 days• Doxycycline 100-200mg po bid for 10-28 days• For AV block or myopericarditis use either of

above regimes with appropriate inpatient monitoring. With resolution of heart block patient may be discharged home on po meds

ILADS

Early disseminated Lyme• Milder symptoms present for less than one year with

multiple Erythems Migrans lesions, constitutional symptoms, and lymphadenopathy, • Treat with oral therapy until no active disease for 4

weeks (4–6 months typical) using same antibiotic doses as outlined for Erythema Migrans • Pregnancy: As in Erythema Migrans, but duration as

above. Treat throughout pregnancy, and do not breast feed.

IDSA treatment of late Lyme disease arthritis

• Doxycycline 100mg bid• Amoxicillin 500mg tid • Cefuroxime 500mg bid• Treat for 28 days• If persistent or recurrent joint swelling retreat

with another 28 days of above antibiotics or 2-4 weeks of IV ceftriaxone

IDSA late neurologic Lyme disease

• This includes encephalopathy's and radiculopathies, Bannwarth syndrome• Treat with ceftriaxone 2 gm qd for 2-4 weeks• “Response to treatment is usually slow and may

be incomplete”• “Re-treatment is not recommended unless

relapse is shown by reliable objective measures”

ILADS Late Disseminated/ Chronic Lyme

• Symptoms present greater than one year, more severely ill patients, and those with prior significant steroid therapy or any other cause of impaired immunity: • Treat adults and pregnant woman with 10 or more

weeks of IV therapy , then oral or IM till asymptomatic for 6-8 weeksChildren: IV therapy for 6 or more weeks, then oral or IM follow up as above.

IDSAPost Lyme disease syndrome proposed

definition•Onset of the following symptoms within 6

months of a documented case of Lyme that has been treated by IDSA guidelines• Fatigue•Widespread musculoskeletal pain• Complaints of cognitive difficulties• Exclusion of any diagnosable disease

Why antibiotic treatments don’t work

• three forms of lyme (spirochete, L-form, cyst) • biofilm• tissue sequestration• patient’s intolerance to treatment: toxicity,

gastritis, mycosis, mitochondrial fatigue• co-infections• evolution of bacteria, i.e. resistance• targeted vs comprehensive treatment strategy

Why treatments don’t work

• Immune evasion• Using proteins that look like ours (ID badges),

avoid recognition and therefore destruction by complement pathway.• Mutate surface proteins. Encysting.• Using proteins that look like ours (feeding

misinformation), activate the immune system non-productively

Page 27: The Lyme Enigma Complexity and Controversy. Lyme Life Cycle Lyme disease is caused by a tick-borne spirochete, Borrelia burgdorferi. Humans are an incidental

Immune Evasion

•Modulation of it’s surface antigens, OspA and OspC• Evades complement pathway: OspC, CD59-like

complement inhibiting protein• OspA potent neutrophil stimulator and inducer of

IL-1b, TNF-a, and IL-6• Induces IL-10 initially to downregulate immune

response• Delayed conversion of IgM to IgG

Comprehensive Support

• anti-inflammatory: diet, herbs, proteolytic enzymes• lymphatics: walking, skin brushing, massage• gastro-intestinal: probiotics, regularity• liver support: phase I and II• brain/nerves: B12, herbals• methylation, glutathione• emotional/spiritual
