The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. RA attacks the lining of the joints (synovium), causing swelling that can result in aching and throbbing, and eventually deformity. Listing a study does not mean it has been evaluated by the U. Even though there have been many advances in the treatment of RA, psoriatic arthritis (Ps A), and other inflammatory arthritis, doctors still do not know what causes this inflammation in joints. Rheumatoid arthritis (RA) is an inflammatory form of arthritis that causes joint pain and damage. It is likely that RA occurs as a result of a complex combination of factors, including a person's genes; lifestyle choices, such as smoking and diet; and things in a person's environment, including bacteria or viruses. This study investigates the hypothesis that bacteria living in a person's mouth and/or intestinal tract are responsible, at least in part, for the development of Rheumatoid Arthritis. The investigators believe that by killing those bacteria with antibiotics, they might be able to understand how the immune system works and, maybe, what causes RA. If you would like to participate in this study, we will first ask you several questions regarding the status of your arthritis, the medications you use or have used in the recent past, your social and dietary habits, and your medical and surgical history.

Doxycycline is used to treat infective diseases because of its broadspectrum efficacy. High dose administration (100 or 200 mg/day) is often responsible for development of bacterial resistances and endogenous flora alterations, whereas low doses (20–40 mg/day) do not alter bacteria susceptibility to antibiotics and exert anti-inflammatory activities. In this study, we wanted to assess the efficacy of both low and high doxycycline doses in modulating IL-8, TNF-α, and IL-6 gene expression in Ha Ca T cells stimulated with LPS. Three experimental settings were used, differing in the timing of doxycycline treatment in respect to the insult induced by LPS: pretreatment, concomitant, and posttreatment.

I was prescribed a three week round of doxycycline because the symptoms seemed to point to Lyme and I had a tick about a month prior. I was also prescribed Ultram for the pain. RA is a chronic inflammatory disease that often leads to joint damage, deformity, and dysfunction. The treatment of this disease has been hampered by an incomplete understanding of its pathogenesis and the absence of identifiable etiologic factors. The etiology of RA has long been suspected to be triggered by infection with bacteria, especially mycoplasma. One approach to investigating the possible role of bacterial infection in RA is empiric treatment with antibiotics. Recent studies of patients with RA of relatively long duration suggest that oral minocycline therapy modestly improves the signs and symptoms of arthritis. Minocycline, while an effective broad spectrum anti-microbial agent, can also suppress collagenase, a degradative enzyme prominent in the pathogenesis of joint destruction. Two important questions remain concerning this approach: 1-Can the clinical efficacy of minocycline in RA be improved by intensifying the antibiotic regimen and/or selectively targeting early disease? Preliminary evidence from experimental animal models has suggested that doxycycline may be effective in preventing or slowing the progression of osteoarthritis (OA), perhaps through its ability to modulate the activity of cartilage-degrading matrix metalloproteases (MMPs). Despite this encouraging animal evidence, no studies have investigated doxycycline in humans with, or at risk for, OA. Here, Brandt et al (Arthritis Rheum 2005;52(7): 2015) examine the potential for doxycycline to slow the progression of unilateral knee OA in obese women. Obese women 45 to 64 years of age with radiographic evidence of moderate (K/L grade 2 or 3) unilateral knee OA were randomized to receive doxycycline 100 mg twice daily or matched placebo for 30 months. Adherence was assessed via electronic monitors affixed to the study drug containers. The primary outcome measure was the change in joint space width (JSW) in the medial tibiofemoral compartment for both the index and contralateral knees. JSW was measured via fluoroscopically positioned semi-flexed radiographs of the knees, obtained at baseline, 16 and 30 months.
