Etiology
- infection with Borrelia species
- transmission by infected ixodid (deer) ticks
- attachment of Ixodes scapularis for at least 36 hours[1]
- recurrent Lyme disease represents reinfection with a different genotype of Borrelia burgdorferi rather than relapse[17]
Epidemiology
- greatest prevalence in:
- southern New England
- middle Atlantic states, southwestern Virginia[30]
- Wisconsin
- Minnesota
- Northern California & Oregon
- Borrelia mayonii identified in Minnesota, Wisconsin, North Dakota
- factors contributing to increase in Lyme disease
- 30,000 cases of Lyme disease are reported to the CDC annually; the actual number of annual cases is roughly 10 times higher[21]
- 3 deaths due to Lyme carditis Nov 2012 - July 2013 (U.S.)[22]
Pathology
- obliterative endarteritis in synovium
- a peptidoglycan in the cell envelope of Borrelia burgdorferi is released but not degraded when the bacterium dies[43]
- the peptidoglycan lingers in synovial fluid & elicits an ongoing immune response*
* systemic administration of the peptidoglycan ellicits acute arthritis in mice[43]
Genetics
- chronic joint disease associated with HLA-DR4, often in combination with HLA-DR2
Clinical manifestations
- early localized disease
- characteristic rash - erythema migrans (60-80%)
- < 30 days after tick bite at site of tick attachment
- confirms diagnosis[1]
- case report shows image of periorbital erythema migrans[28]
- macular skin rash noted for Borrelia mayonii[31]
- generally develops 3-20 days after tick bite
- viral-like illness
- may present as fever & headache without rash[25]
- images[33][34]
- characteristic rash - erythema migrans (60-80%)
- spirochetemia
- weeks to months after initial tick bite
- multiple sites of erythema migrans[49]
- fever, headache, myalgias
- syncope
- dizziness
- shortness of breath
- cardiac manifestations
- substernal chest pain or palpitation
- mild congestive heart failure
- fluctuating AV nodal block
- complete heart block may develop (usually transient)[2][15][49]
- mild pericarditis
- neurological manifestations
- lymphocytic meningitis
- radiculitis radiculoneuritis
- often multifocal, polyradiculitis, meningoradiculitis[41]
- motor fibers & sensory fibers
- cranial neuritis[11] (image)[33]
- most commonly facial (CN VII) palsy (Bell's palsy)[46]
- bilateral CN VII palsy in an endemic area is diagnostic
- confused speech, somnolence, & visual impairment noted with Borrelia mayonii[31]
- acute, oligoarticular inflammatory arthritis[1]
- nausea/vomiting may be more common with Borrelia mayonii[31]
- late disease
- may develop years after initial tick bite & without evidence of antecedent disease
- chronic neurological manifestations
- chronic arthritis
- generally monoarticular or oligoarticular involving large joints
- knee is most commonly affected joint
- minimally symptomatic despite large effusions
- episodes may last days to months or may become chronic
- image[33]
- late stage skin manifestations
- severe fatigue is rare, less severe fatigue is uncommon[27]
- fibromyalgia may be associated with previous Lyme disease
- asymptomatic infection is uncommon (7% of all cases)
* images of erythema migrans[49]
Diagnostic criteria
- erythema migrans coupled with compatible epidemiology sufficient for diagnosis in early disease[1]
Laboratory
- Borrelia burgdorferi antibody in serum
- IgM appears 4 weeks after exposure
- IgG appears 6-8 weeks after exposure
- indicated for early disseminated & late Lyme disease, not indicated for acute (early) localized Lyme disease
- serologic testing for Lyme disease for hikers in edemic region presenting with monoarticular arthritis regardless of history of tick bite[1]
- ELISA now accepable alternatives to Western blot
- false positives with
- other spirochetal infection
- bacterial endocarditis
- parvovirus B19
- Epstein-Barr
- rheumatoid arthritis
- systemic lupus erythematosus
- false positives with
- Borrelia burgdorferi immunoblot IgG (Western blot)
- confirmatory test (IgG) - more specific than ELISA
- identifies IgG antibodies against specific components of Borrelia burgdorferi
- negative immnoblot IgG when symptoms have been present for >= 1 month excludes Lyme disease (no further testing is indicated)[1]
- Borrelia burgdorferi-specific immune complexes[4]
- seroreactivity often positive for months after antibiotic treatment of early disease & for years after treatment of late infection
- serologic tests for Lyme disease yield disparate results[12]
- Polymerase chain reaction for Borrelia Burgdorferi DNA
- used to detect Borrelia Burgdorferi DNA in:
- blood
- cerebrospinal fluid (CSF) sensitivity is poor[41]
- urine
- skin
- synovial fluid
- more sensitive than culture
- may detect Borrelia before antibody response
- more specific than ELISA
- offers no advantage over serologic testing[1]
- not widely available
- used to detect Borrelia Burgdorferi DNA in:
- lumbar puncture with CSF analysis for neuroborreliosis[1]
- lymphocytic pleocytosis
- elevated CSF protein
- oligoclonal immunoglobulins
- CSF glucose may be normal
- CSF/serum antibody index (ELISA not immunoblot) best method[41]
- CSF findings in Lyme meningitis indistinguishable from other forms of aseptic meningitis[1]
- synovial fluid analysis
- inflammatory with neutrophil predominance
- Borrelia Burgdorferi DNA
- less sensitive than Borrelia burgdorferi immunoblot IgG for late Lyme arthritis[1]
- cultures tend to be negative[1]
- see ARUP consult[14]
- un-approved test using immunostaining enriched culture specimens with or without PCR, considered positive when either immunostaining or PCR is positive
Diagnostic procedures
- electrocardiogram
- lumbar puncture for suspected neuroborreliosis
Radiology
- CT of head (neuroimaging) unnecessary for suspected neuroborreliosis
- neuroborreliosis rarely associated with parenchymal brain lesions[1]
Complications
- Lyme carditis, potentially fatal (sudden death)[22][26]
- 1% of patients with Lyme disease
- rarely fatal, mortality 0.002%
- complete heart block is usually transient[49]
- most patients with Lyme carditis are male[26]
- 42% with erythema migrans[26]
- patients with Lyme neuroborreliosis have increased risks for hematological cancer & skin cancers, otherwise similar long-term health outcomes to their unaffected peers
- post Lyme disease syndrome (chronic Lyme disease)
- non-specific but disabling symptoms
- repeat episodes of erythema migrans in appropriately treated patients due to reinfection, not to relapse[35]
Differential diagnosis
- southern tick-associated rash illness[1] (clinically indistinguishable from Lyme disease)
- coinfection with Anaplasma phagocytophilum since tick vectors are the same
- anaplasmosis associated with leukopenia & thrombocytopenia
Management
- general
- risk of disease after tick bite is low
- transmission of Borrelia from tick to person rarely occurs unless tick has attached & fed for at least 36 hours
- see prophylaxis (after tick bite) below
- antibiotic therapy is generally curative
- risk of disease after tick bite is low
- oral agents for treatment of early disease
- with manifestations of
- isolated facial palsy
- carditis (except 3rd degree heart block)
- Lyme arthritis
- acrodermatitis chronica atrophicans
- erythema migrans
- may be too early for serologic confirmation
- 1st line antibiotics
- doxycycline 100 mg PO BID for 10-21 days
- amoxicillin 500 mg PO TID
- if tetracyclines contraindicated: pregnant women; children < 8 years of age
- cefuroxime 500 mg PO BID
- alternative agent: azithromycin 500 mg PO QD
- Jarisch-Herxheimer reaction (5-10%)
- occurs within 1st days of treatment
- reaction is mild, generally lasting < 1 day
- with manifestations of
- intravenous antibiotics:
- indications
- neurologic manifestations (except isolated facial palsy)
- severe carditis (3rd degree AV block)
- 3rd degree AV block resolves in antibiotics
- hospitalize with cardiac monitoring during treatment[2][15]
- temporary cardiac pacemaker if indicated[2][15]
- refractory arthritis
- erythema migrans
- ceftriaxone 2 g IV QD for 14-28 days (1st line)
- alternative agents
- Penicillin G 20 million units IV QD for 14-28 days
- cefotaxime 2 g IV every 8 hours[1]
- 12 weeks of oral doxycycline or clarithromycin plus hydroxychloroquine following IV ceftriaxone no better than placebo[38]
- indications
- late stage (incubation period months to years)
- some patients with late features are refractory to antibiotic therapy
- oral therapy for 28 days (confirmed Lyme arthritis)
- IV antibiotics to 14-28 days (confirmed Lyme encephalopathy)
- post Lyme disease syndrome (do not diagnose chronic Lyme disease)
- management is symptomatic
- prolonged administration of antibiotics contraindicated[1]
- retreatment of persistent Lyme disease controversial[15]
- consider coinfection with anaplasmosis[36]
- synovitis
- prophylaxis after tick bite
- risk of contracting Lyme disease from tick bite is low, thus prophylaxis is generally not recommended
- however, a single 200 mg oral dose of doxycycline within 72 hours is 87% effective[5][6]
- consider doxycycline prophylaxis in endemic areas[5][6]
- Fibromyalgia associated with previous Lyme disease does not respond to antibiotic therapy
- vaccination
- recombinant outer surface protein A (OspA) vaccine is well tolerated by human volunteers
- adequate levels of IgG against OspA to inhibit in vitro replication of Borrelia burgdorferi are obtained by vaccination
- tick repellant (DEET)
- prognosis:
- 73% of children with confirmed Lyme disease with complete recovery
- 27% with non-specific residual symptoms at 5 years allegedly not different from uninfected children[16]
Notes
- unproven treatment for "chronic Lyme disease" can cause serious adverse events[39]
- long courses of IV antibiotics or immunoglobulins
