Active clinical trials for "Staphylococcal Infections"

Prosthetic joint infection is a devastating complication of total joint arthroplasty ultimately leading to the failure of the total joint arthroplasty function and possibly death. Optimal treatment requires the resection of the infected total joint arthroplasty followed by prolonged parenteral antimicrobial therapy. This procedure is followed by reimplantation of a new total joint arthroplasty at a later date. Surgical debridement and retention of the infected total joint arthroplasty offers a more conservative surgical approach and has been proven to be cost-effective in selected groups of patients. Traditional medical therapy for staphylococcal infection would require an initial parenteral antimicrobial followed by chronic oral non-rifampin containing antimicrobial suppression regimen for the life of the total joint arthroplasty. With this strategy the success rate is close to 30%. Recently, several prospective studies of patients with THA, TKA and fracture fixation device infections conducted in Europe showed that the success rate with a 3-6 month course of a quinolone-rifampin combination is effective in 70% to 100% of cases. The proposed study will be a prospective open label observational cohort that will evaluate the outcome of Patients with S. aureus PJI treated with a medical regimen that includes oral levofloxacin- rifampin and debridement and retention of components. This medical regimen was approved for use by the Orthopedic Infectious Diseases focus group, Mayo Clinic, Rochester. 15 patients will be enrolled over a one-year period and followed up to minimum of 1 additional year. The outcome of this group will be compared to a historical group that is treated with traditional therapy.

Background: - Staphylococcus aureus, or staph, is commonly found on the skin and in the respiratory system. Sometimes people who get sick with staph infection do not get better with standard treatment. These staph infections can be serious and even deadly. Researchers want to find out why some people are more likely to get the infection. Objectives: - To look at the immune response of the skin when it is exposed to bacteria. Eligibility: People age 2 65 with hyper IgE syndrome (HIES) and those with recurrent staph infections. Healthy volunteers. Design: Participants will be screened with medical history, physical exam, and blood tests. Over 1 5 days, participants may have blood tests and a skin and nasal swab. They may have additional tests if needed. If they had a recent biopsy, researchers may ask for a sample from it. Some participants will spend the night at the clinic. Their vital signs will be taken and they will have blood drawn. Some participants will take aspirin or ibuprofen starting 2 days before their stay. Some participants will have blisters created on the inside of their forearm. Suction will pull a layer of skin from their arm. Skin will be removed. Different solutions will be applied to the blisters. Up to 3 biopsies may be taken. Children will not have blood tests or biopsies. Participants will be called every day for 10 days, then at 30 days after the procedure. Participants will have a follow-up visit 10 days after the procedure. Participants who did not get blisters or biopsies will not have any follow-up appointments.

Staphylococcus aureus bacteremia: impact of an intervention program in improving the clinical management and review of the clinical and molecular epidemiology.

This randomized phase III trial studies chlorhexidine gluconate cleansing to see how well it works compared to control cleansing in preventing central line associated bloodstream infection and acquisition of multi-drug resistant organisms in younger patients with cancer or undergoing donor stem cell transplant. Chlorhexidine gluconate may help reduce bloodstream infections and bacterial infections associated with the central line.

The primary objective is to demonstrate that the risk of S. aureus bacteremia (SAB) is correlated to the RNA III and SprD RNAs expression

Our hypothesis for the DERAIL MRSA program is that one can safely remove the colonization risk from nearly all residents (patients) in a way that does not interfere with the desired life-style for persons in these facilities and thereby reduce the risk of infection and lower the cost of care by avoiding preventable disease.

The prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) colonization and infections have been increasing in the general population, including the pediatric population. It has been reported that MRSA colonization persists for up to four years, and therefore the youngest pediatric patients, specifically those who are less than 2 years of age, have a high risk of prolonged colonization during a period of time when they are susceptible to significant skin and soft tissue infections (SSTIs) attributable to MRSA. Once prolonged colonization takes place, recurrent SSTIs are commonplace, resulting in substantial morbidity and in some cases mortality, as well as a significant cost to the healthcare system. Individuals colonized with MRSA have an increased risk of developing MRSA infections, which range from mild disease, such as carbuncles, to severe infections, such as necrotizing pneumonia and toxic shock syndrome. The prevalence of severe MRSA infections is also greatest in neonates and infants, where increased MRSA colonization has been observed. In the early infant period, the most common manifestation of MRSA disease is pustular skin lesions, which affect approximately 5% of the general population, with MRSA-colonization being a major risk factor for this disease. Moreover, the prevalence of pustular disease is increasing in the general population, and there are numerous case reports of invasive, life-threatening MRSA disease in the early infant period. Corresponding to the increasing prevalence in the community, the carriage of MRSA in pregnant women has also escalated, and vaginal carriage is significant in pregnant women. As an analogy, maternal vaginal Group B Streptococcal (GBS) colonization is the major risk for infant colonization regardless of whether early or late neonatal colonization or disease occurs. It is quite feasible that vaginal MRSA carriage predisposes newborns to colonization during the birthing process; however, this mechanism has not yet been well studied. There are other mechanisms implicated for early infant colonization, including close contact with MRSA-colonized mothers through daily care and breastfeeding. MRSA colonization in one household member greatly predisposes colonization in others; therefore, early infant colonization could result from contact with other MRSA-colonized individuals in a household. Currently, it is not clear which factors are the most important in influencing early infant MRSA colonization and subsequent infection. Not only is the prevalence of MRSA colonization and infection on the rise, but there have been few if any measures that have been established to prevent colonization and subsequent infection in adults and children. Eradication measures have shown limited long-term benefit. If vertical transmission of MRSA can be established as a critical event in the pathogenesis of disease, potentially effective strategies could be tested, and possibly the spread of MRSA in the community interrupted. Hypotheses and Specific Aims: Identify the proportion, rate and time of MRSA colonization in infants born to mothers with and without MRSA colonization; Compare risk factors for infant MRSA colonization in these two groups; Determine the prevalence and risk factors for developing MRSA infections in the MRSA-colonized infant.

Staphylococcus aureus (S.aureus) is a bacterium that causes many painful skin and soft tissue conditions, such as scalded-skin syndrome, boils, or impetigo. Serious cases may result in deadly complications but S.aureus can usually be treated successfully with antibiotics. There are, however, certain strains which cannot be treated with standard antibiotics. Methicillin-resistant staphylococcus aureus (MRSA) is one such strain. MRSA is increasingly being seen in both hospital and community settings, making it a serious public health issue. People with Atopic Dermatitis (AD), particularly those with a history of Eczema Herpeticum (EH), may be at greater risk for infection by MRSA. The reason for this higher risk is unknown but may be linked to extended treatment with staphylococcus antibiotics in addition to the absence of certain proteins on their skin, which have immune function. The purpose of this study is to determine the reasons for MRSA infection in AD participants with and without a history of EH.

Background: Community acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is an emerging pathogen of the 21st century whose incidence as a cause of local and invasive infections has significantly increased, especially in previously healthy term and near term newborns. The etiology of the increasing incidence of infection in previously healthy term and near-term newborns remains unclear. Hypothesis: The incidence of previously healthy newborns infected with CA-MRSA skin & soft tissue (SSTI) and invasive infections is higher in those born to mothers colonized with CA-MRSA. Pregnant women colonized with CA-MRSA are at higher risk for post-partum infection with this organism. Specific Aims: To determine the incidence of nasal and vaginal colonization with CA-MRSA in pregnant women and determine the genetic similarities of these strains. To study CA-MRSA transmission dynamics and evaluate the incidence of SSTI and invasive infections in newborns born to S. aureus colonized mothers. To study the efficacy of attempted decolonization in CA-MRSA colonized mothers in decreasing the incidence of transmission and development of SSTI and invasive infections in their infants during the first month of life. Potential Impact: Understanding the epidemiology of the transmission dynamics of CA-MRSA in previously healthy newborns will provide important information to support the development of strategies aimed at the interruption of transmission and prevention of infection caused by CA-MRSA in newborns, as well as in pregnant women. This will also allow for the development of infection control strategies to prevent the spread of this organism among post-partum units and nurseries.

Staphylococci represent the first etiologic agents of bone and joint infection (BJI), leading glycopeptides use, especially in case of methicillin-resistance or betalactam intolerance. Teicoplanin may represent an alternative to vancomycin because of its acceptable bone penetration and possible subcutaneous administration. Various studies have shown that teicoplanin pharmacodynamic profile was superior compared to vancomycin regarding bone diffusion. Few studies have investigated the use of teicoplanin in BJI, particularly through subcutaneous administration. The aim of this study assesses the efficacy and tolerance of teicoplanin in S. aureus BJI, especially focusing on subcutaneous use. This study is a retrospective single-center observational cohort study (2001 to 2011) including all consecutive patients managed at our institution receiving teicoplanin as part of S. aureus BJI treatment.
