Disease

Clinical Manifestations
• Early Lyme Disease, localized
– Days-weeks
– Erythema migrans (EM)
• No symptoms other than rash in 20-30%
– Flu-like symptoms (70-80%)
• Headache = meningitis-like
– Flu-like syndrome without rash
• Uncommon
– Many unaware of tick bite

• 42F gardener
• Asymptomatic
– Growing rash over 5-7d
– Husband “worried”

Early Localized Lyme: Clinical
Manifestations and Diagnosis
• Erythema migrans
– At tick bite site, 7-14d average
– >5 cm = secure diagnosis
• Unsure? Observe for expansion
• Characteristic rash + epidemiology = Lyme
– Clinical diagnosis sufficient: no need for lab testing
– Serology insensitive for early disease
– Uncertain: Observe and obtain acute +
convalescent (4-6 wk) serology
June 2013
Wormser GP et al. Clin Infect Dis 2006;
43:1089–134
18
Early Lyme Disease
• Early disseminated Lyme
– Weeks-months
– Multiple erythema migrans
• Usually with flu-like symptoms, fever
– Neurologic (Bell’s palsy, radiculopathy, meningitis)
• Rash may occur simultaneously
– Musculoskeletal (arthritis, tendonitis, bursitis)
– Cardiac (AV block, rare carditis)
• Objective symptoms PLUS serology or
erythema migrans history

Case Presentation
• 53-year-old man awoke drooling on the
morning of today’s urgent office visit
– 4-7 days earlier, he had slight flu-like
symptoms and headache that resolved
– No rash
– Golfer
– Resident of Rockingham County
June 2013

21
Diagnosis – Facial Palsy
• Up to 25% due to B. burgdorferi
– Long Island
• Serology may take 4-6 wks to turn positive
– If untreated, recheck if initially negative
• Lumbar puncture optional
• 99% recover without antibiotic therapy
– Main role of abx: prevent late disease

Early Disseminated Lyme Disease:
Neurologic Manifestations
•
•
•
•
•
CN palsies
Radiculoneuritis
Mononeuritis multiplex
Meningitis
Encephalomyelitis
(rare)
• Optic Neuritis
– children >> adults
• Possible associations
– Hearing loss
June 2013
• Usually afebrile
• CSF
– <10% PMNs
– May be confused with
viral meningitis
• Most seropositive at
presentation
• Other tests:
– Helpful: CSF index,
intrathecal Ab production
– Not helpful: PCR
Wormser GP et al. Clin Infect Dis 2006;
43:1089–134
23
Clinical Manifestations of Late
Infection (Months-to-Years Later)
• Arthritis
– Usually large weight
bearing joint
– Almost 100% have knee
involvement
• Others: hip, ankle, TMJ
– 100% seropositive IgG
• including WB
– Synovial fluid
• >2000-25,000 WBC
• May have positive PCR if
not previously treated
• ~10% antibiotic refractory
June 2013
Wormser GP et al. Clin Infect Dis 2006;
43:1089–134
24
Neurologic Manifestations of Late
Infection
• Less common now compared with initial reports from
1970’s-1980’s
• Encephalopathy
–
–
–
–
Objective cognitive findings
CSF may be normal
Non-infectious?
Rare: 7 pts dx in 5 yrs by IDSA panel members
• Encephalomyelitis
– MRI abnormalities
– Rare in US: 1 pt dx in 5 yrs by IDSA panel members
June 2013
Wormser GP et al. Clin Infect Dis 2006;
43:1089–134
25
More Neurologic Manifestations of
Late Infection
• Peripheral Neuropathy
–
–
–
–
–
CSF normal
Stocking/glove paresthesia
Sensory findings
Intermittent radicular pain
Rare (9 patients in 5 years by IDSA Lyme panel
members)
• All late Neuroborreliosis: expect positive serology and
CSF antibodies
June 2013
Wormser GP et al. Clin Infect Dis 2006;
43:1089–134
26
Neurologic Manifestations of Late
Infection
• Caveats
– MRI reports often include Lyme disease in
the differential diagnosis
• Treat as unlikely unless proven otherwise
• Consider other diagnosis if Lyme serology
negative
– Intrathecal antibody production may persist
for years despite antibiotic therapy
June 2013
27
Lyme disease: Antibiotics
• Antibiotic-responsive illness
– 10-21d for early infection: oral doxycycline/amoxicillin
– 14-28d for late infection: orals or ceftriaxone IV
– Rare second courses of treatment needed
• Late manifestations from untreated infection
• Subjective symptoms may persist after abx
– More common in women
– Increased with longer duration of untreated infection
– No convincing evidence of persistent infection after abx

Lyme Disease Issues
• Diagnosis
– Unlike most bacterial infections, diagnosis is clinical
• Bacteria hard to detect by culture, PCR, microscopy
• Serological tests = laboratory diagnostic standard
– Up to 60-70% early Lyme (EM) seronegative
– EM is only characteristic finding
• Absent or unrecognized in 10-30%?
• Treatment: Late lyme arthritis
– ~10% have persistent arthritis unresponsive to abx
• Fatigue after early Lyme Disease
– 25% at 3 months; ≥5% (?) after 1 year

Lyme Disease: Expectations
• Subjective symptoms post-treatment
– Prospective studies (treated erythema migrans)
• 24% with mild symptoms at 3 months
– Fatigue, aches, neurocognitive symptoms
• 5-17% with symptoms at 6-12 months
• Culture confirmed LD (n = 96)
– 81 f/u (mean 5.6 yrs): 10% with symptoms
– 4% with symptoms at every visit

– Coxiella burnetti (Q
fever)1
– Brucella2
• Viral
– EBV3
– Viral hepatitis4
– Viral Meningitis5
• Parasitic

788 “Lyme” Patients Presenting to
a Lyme Center
• Active Lyme disease: 23%
• Prior Lyme disease: 20%
• Not Lyme disease: 57%
• Implication: Serology has poorpredictive value in patients without
objective signs and symptoms
June 2013
Steere AS, et al. JAMA 1993;269:1812
37
Lyme Serology: Two-Tier Testing
• First: ELISA/EIA/IFA Screen (Total AB)
• Second: Western blots (immunoblots)
– IgM:
• Need 2/3 bands: 23,39,41 kDa
• Caution: Use only for illness < 1 month
– Positive IgM WB alone = frequent false (+) Lyme
diagnosis
– Cross reactive with other bacterial and non-bacterial
antigens
June 2013
MMWR 1995;44:590
38
Lyme Serology
• Western blot
– IgG: Need 5 of 10 potential bands
• 18,23,28,30,39,41,45,58,66 or 93 kDa
– More reliable test
– Usually positive by wk 4-6 of infection
– Only use this test for sx > 6 wks.

MMWR 1995;44:590
39
Lyme testing: False Positives
• Non-specific sx
• Westchester NY
– 50/182 false (+) IgM
immunoblot
– 78% unnecessary
antibiotics
June 2013
Seriburi V et al. Clin Microbiol Infect 2012; 18: 1236–1240
40
Lyme Serologies
• Immunological test
– Host response to infection
– Does NOT detect actual bacteria
• Tests do NOT distinguish between
active or inactive disease
– 40-60% seropositive 25 years after initial infection
– No reason to follow titers routinely
June 2013
Clin Infect Dis. 2001 Sep 15;33(6):780-5
41
Common Clinical Scenarios with
Improper Use of Serology
1) EIA only, no Western Blot (WB)
2) WB only (without EIA/IFA)
–
>50% population reactive to 1 or more antigens
3) Using the IgM WB alone for symptoms >1 mo
–
Usually false positive
4) Serology at time of erythema migrans
5) Treating tests that “stay positive”
6) Testing samples by WB other than serum

Longer-term Antibiotic Courses Do Not
Influence Outcomes
• Evidence: Prospective trials, shorter term
outcomes – longer therapy without benefit
– Early Lyme disease1
(n=108: PCN, TCN, erythromycin)
– Erythema migrans2
(n=180: 10d doxy +/- CTX v 20d doxycycline)
– Late Lyme disease3
(n=143: 14d vs. 28d CTX)

Persistent Symptoms – Controlled Trial
Antibiotic Treatment v. Placebo
• Two studies of patients with clinical Lyme Disease
– 78 pts seropositive (IgG antibodies); 51 seronegative
• Entry criteria
– Well-documented Lyme disease
– Prior antibiotic treatment
– Persistent musculoskeletal pain, neurocognitive symptoms
(>70%), dysesthesia, fatigue (90%)
– Average duration of symptoms: 4 years
• Ceftriaxone 2 gm IV q24h x 30d, then doxycycline
200 mg x 60d vs. matched placebos
• Primary outcome: SF-36 scale measuring healthrelated quality of life at day 180

Cognitive Function: Lyme disease
• Companion study, n=129
• Used cognitive objective testing, mood scores
• >70% gave cognitive dysfunction as
complaint at study entry
– Patients had normal baseline neuropsych testing
– Suggests symptom report ≠ objective evidence
• No significant differences between groups

Science: How likely > 1 microbe?
• Depends on
geography
– Nymph I. scapularis
ticks 2-5%
– Adults 1-28%
• Usually B.
burgdorferi + other
• I. scapularis does
not transmit:

–
E. chaffeensis
