  • Title: Detection of Borrelia burgdorferi DNA in urine of patients with ocular Lyme borreliosis.
    Author: Pleyer U, Priem S, Bergmann L, Burmester G, Hartmann C, Krause A.
    Journal: Br J Ophthalmol; 2001 May; 85(5):552-5. PubMed ID: 11316715.
    Abstract:
    AIM: To evaluate the diagnostic value of the polymerase chain reaction (PCR) to detect Borrelia burgdorferi DNA in patients with ocular Lyme borreliosis. METHODS: Of 256 consecutive uveitis patients six selected individuals with clinical evidence for Lyme borreliosis and 30 patients with non-Lyme uveitis were enrolled. Lyme serology was performed by ELISA and western blotting. Urine samples were examined by an optimised nested polymerase chain reaction (PCR) protocol. RESULTS: Only four of six uveitis patients suspected for Lyme borreliosis were ELISA positive, while all six subjects showed a positive western blot. B burgdorferi PCR was positive in all of these six patients. Whereas two of the 30 controls had a positive Lyme serology, B burgdorferi DNA was not detectable by PCR in any sample from these patients. CONCLUSIONS: PCR for the detection of B burgdorferi DNA in urine of uveitis patients is a valuable tool to support the diagnosis of ocular Lyme borreliosis. Moreover, these patients often show a weak humoral immune response which may more sensitively be detected by immunoblotting.
