OBJECTIVES To compare the antimicrobial activity of tigecycline and doxycycline against multiple isolates of Borrelia burgdorferi. METHODS In vitro antimicrobial assays were carried out using a microdilution assay. The time needed to inhibit, immobilize and kill the B31 strain of B. burgdorferi was determined. The MIC, MBC and concentration needed to immobilize the organism were determined fo...
BACKGROUND In this study, we assess the effectiveness of inhaled doxycycline, a tetracycline antibiotic displaying matrix metalloproteinases (MMP) inhibitory effects to prevent allergen-induced inflammation, hyperresponsiveness and remodeling. MMPs play key roles in the complex cascade of events leading to asthmatic phenotype. METHODS Doxycycline was administered by aerosols by the mean of a ...
Probiotics and antibiotics are widely used in poultry and may alter drug bioavailability by affecting the expression of intestinal ATP-binding cassette (ABC) efflux transporters. Therefore the aim of the present investigation was to evaluate the effect of Lactobacilli probiotics, administered alone or in combination with doxycycline, on the expression of ABCB1 (gene, encoding P-glycoprotein), A...
BACKGROUND/AIMS Doxycycline is a broad spectrum antibiotic that chelates metal ions and is frequently used as part of the treatment of ocular surface diseases. Its therapeutic value has been ascribed to an ability to inhibit matrix metalloproteinase (MMP) activity and both MMP and IL-1 synthesis. The aim of this study was to evaluate the role of doxycycline as an inhibitor of corneal MMPs and a...
The antimicrobial activity of a wound dressing is a key factor for preventing and treating wound infection. The current study evaluated the physiochemical properties and antimicrobial activities of semi-IPNs (interpenetrating polymer networks) based on chitosan/polyvinyl alcohol (PVA) films and nanofibers as candidates for wound dressings and investigated the effects of morphologies (nanofibrou...
BACKGROUND The aim of this study was to compare the response of doxycycline and bleomycin in pleurodesis of malignant pleural effusions. MATERIALS AND METHODS The radiologic and clinical responses of doxycycline and bleomycin in pleurodesis of malignant pleural effusions were compared in this randomized clinical trial. Forty-two patients were randomized to receive either bleomycin 45 mg or do...
BACKGROUND Limited data exist on the effectiveness of ceftriaxone plus doxycycline in the treatment of patients hospitalized with community-acquired pneumonia (CAP). METHODS We performed a retrospective cohort study of all adults hospitalized for pneumonia between January 1999 and July 2001 at an academic medical center. Outcomes were compared for patients with CAP treated with ceftriaxone pl...
OBJECTIVES Allergic rhinitis (AR) is a chronic upper respiratory tract disease that inflames the mucous membranes of the nose and occurs when circulating inflammatory cells including eosinophils and basophils migrate to and accumulate in the inflammation area by passing through the interstitium and capillary walls. To pass through these barriers, the inflammatory cells degrade extracellular mat...
OBJECTIVES The main objective of the present study is to study the therapeutic efficiency of doxycycline in a double-blinded randomised phase II study in a cohort of patients with sporadic Creutzfeldt-Jakob disease (sCJD). METHODS From the National Reference Center of TSE Surveillance in Germany, patients with probable or definite sCJD were recruited for a double-blinded randomised study with...
INTRODUCTION Benzathine penicillin G is the treatment of choice for syphilis, but doxycycline and tetracycline are effective second-line treatments. The objective of this study was to assess the serological response to treatment for early syphilis with benzathine penicillin compared with doxycycline or tetracycline. METHODOLOGY We examined rapid plasma regain (RPR) serological test results of...
