Filter by:Test and evaluate a new diagnostic method (SRM-MS/MS: Selected Reaction Monitoring- Mass spectrometry) for Lyme Borreliosis on human skin biopsies. Patients included are those with the early skin manifestation (erythema migrans). This new proteomic method will be compared to the two existing method: culture of Borrelia and PCR detection of Borrelia (DNA detection of the bacteria).
The main objective of this study is to characterize the inflammatory proteins, gene polymorphisms, and transcriptome profiles in patients with erythema migrans to gain better insight into pathogenesis of early Lyme borreliosis and to define new immune modulators that could serve as biomarkers of disease activity.
The main purpose of this study is to compare effectiveness of two different culture media for cultivation of Borrelia burgdorferi sensu lato from skin specimens obtained from patients with erythema migrans.
Background: - While doxycycline is a standard antibiotic for treatment of erythema migrans in Europe as well as in the USA, the effectiveness of cefuroxime axetil in the treatment of adult patients with erythema migrans has been assessed only in the USA where the causative agent of Lyme disease is Borrelia burgdorferi, but not in Europe where the main etiologic agents are B. afzelii and B. garinii. - Controversy exists over the significance and even the existence of post-Lyme disease symptoms because of the high rate of similar background symptoms in the general population. Purpose: The two main purposes of this European, prospective clinical trial in which doxycycline and cefuroxime axetil are compared in the treatment of adult patients with erythema migrans and which included a control group to address the significance of post-Lyme disease symptoms are: - To assess and compare the effectiveness of doxycycline and cefuroxime axetil in the treatment of erythema migrans using clinical and bacteriological criteria (noninferiority testing approach), and - to compare the frequency of post-Lyme disease symptoms in adult patients treated for EM with antibiotics and the frequency of similar symptoms in control subjects without Lyme disease.
The investigators will compare the outcome of three groups of erythema migrans patients treated with doxycycline: a group without any accompanying symptoms, with mild symptoms and with severe symptoms that require lumbar puncture.
Tick borne diseases are increasing in Norway. Lyme borreliosis is the most common infection. Erythema migrans is mainly diagnosed and treated in general practice. There is disagreement about what antibiotic treatment that should be given. An RCT with the three most common antibiotics used, will support data for revision of national guidelines.
The purpose of this study is to compare the efficacy and safety of 15-day ceftriaxone versus 15-day doxycycline treatment in patients with multiple erythema migrans.
The purpose of this study is to compare the efficacy of 15-day versus 10-day doxycycline treatment in patients with erythema migrans.
This study will analyze cells from erythema migrans lesions, the "bull's eye" rash of Lyme disease. Little is known about what happens in the skin when it is infected with Borrelia burgdorferi, the bacteria that cause Lyme disease. This study will examine and compare laboratory findings in skin biopsies from people with Lyme disease and from healthy normal volunteers to try to better understand the infection. Healthy volunteers and people with untreated erythema migrans rash who are 18 years of age or older may be eligible for this study. All participants undergo a clinical examination, blood tests, between two to four skin biopsies (removal of a small piece of tissue for laboratory examination), and complete two health questionnaires. The biopsies are taken from the erythema migrans lesion in patients with Lyme disease and from skin on the legs, forearms, buttocks, or side from healthy volunteers. To collect the tissue, the skin at the biopsy site is numbed with injection of a local anesthetic and a sharp instrument is then used to remove a round plug of skin about the size of a pencil eraser. The wound may be closed with one or two sutures, or allowed to heal without sutures. The sutures are removed after a week to 10 days. Patients with Lyme disease receive treatment for their condition. In addition, at the time the sutures are removed and at 4 weeks, 6 months, and 12 months after their first visit they fill out a questionnaire and have additional blood tests.
