PY - 2021 T2 - Current Diagnosis & Treatment: Rheumatology, 4e AB - ESSENTIALS OF DIAGNOSISLyme borreliosis should be considered in individuals who have a reasonable risk of exposure to Borrelia burgdorferi-infected ticks and who present with a characteristic complex of signs and symptoms.Classic clinical features occur in stages:Early localized infection (3–30 days after tick bite): a single hallmark skin lesion erythema migrans (EM), occasionally associated with fever, malaise, headache, arthralgias, and myalgias. These constitutional symptoms can occur in the absence of EM, but this is unusual.Early disseminated infection (weeks to a few months after tick bite): signs include multiple EM lesions, often with associated fever, migratory arthralgias, and myalgias; carditis manifested primarily as AV nodal block; neurologic features, including cranial nerve palsies (especially involving the facial nerve), lymphocytic meningitis, and radiculoneuropathies.Late infection (several months to years after tick bite): arthritis, including monoarticular and migratory pauciarticular arthritis; rarely neurologic features such as peripheral neuropathies or chronic mild encephalopathy.Supporting serologic evidence of exposure to B burgdorferi is present in the majority of cases but can be absent in early infection.
