Skin biopsies of 36 patients with erythema migrans and
acrodermatitis chronica atrophicans (ACA) before therapy and those of 8 patients after therapy were examined for Borrelia
burgdorferi DNA by PCR. Skin biopsies of 27 patients with
dermatological diseases other than Lyme borreliosis and those of 10 healthy persons were examined as controls. Two different primer sets
targeting 23S rRNA (PCR I) and 66-kDa protein (PCR II) genes were used.
PCR was performed with freshly frozen tissue (FFT) and
paraffin-embedded tissue (PET). For FFT specimens of erythema migrans,
73% were positive by PCR I, 79% were positive by PCR II, and 88%
were positive by combining PCR I and II. For PET specimens, PCR was
less sensitive (PCR I, 44%; PCR II, 52%). For FFT specimens of ACA,
PCR I was positive for two of five patients and PCR II was positive for four of five patients. B. burgdorferi was cultured from
79% of the erythema migrans specimens but not from any of the ACA
lesions. Elevated B. burgdorferi antibodies were detected
in sera of 74% of erythema migrans patients and 100% of ACA patients.
All urine samples were negative by PCR II, whereas PCR I was positive
for 27%. However, hybridization of these amplicons was negative.
Sequencing of three amplicons identified nonborrelial DNA. In
conclusion, urine PCR is not suitable for the diagnosis of skin
borreliosis. A combination of two different primer sets achieves high
sensitivity with skin biopsies. In early erythema migrans infection,
culture and PCR are more sensitive than serology.
