Active clinical trials for "Infections"

CMV infection is common in transplant patients and can cause graft loss. CMV is a major factor in increasing morbidity, and post-transplant costs. The CMV infection is associated with many deleterious indirect effects including rejection, interstitial fibrosis and tubular atrophy, mortality. In addition to the potential for undesirable clinical outcomes associated with CMV, there is also a negative economic aspect. Patients who developed CMV events have been found to use significantly more inpatient and outpatient resources than patients without CMV disease. Universal prophylaxis is associated with high treatment cost and the potential for drug-related toxicity. It can be speculated that use of EVR may offer additional economic benefits in terms of decreased utilization associated with prevention of CMV disease, and reduce use of costly prophylaxis. Any efforts to reduce costs in renal transplants are very important and may have a great impact in total cost of a renal program. And the other hand, the clinical data suggest that EVR is associated with a decrease in CMV incidence compared to mycophenolic acid (MPA). CMV replication is dependent upon 1 ou 2 mTor pathways and in vitro studies support an association between mTor inhibitors and decreased CMV infection and disease. In cardiac transplantation, the use of EVR was associated with a lower incidence of CMV events. Some clinical trials data have also shown that use of EVR was associated with a lower incidence of CMV infection compared to MPA following renal transplantation. Brennan et al compared the incidence of CMV in three clinical trials using EVR versus MPA in De Novo renal transplants. They pooled for analysis the studies B201, B251 and A2309, all double-blind, randomized, parallel-groups that compared the incidence of freedom form and incidence of CMV between EVR groups and MPA groups. The results of this pooled analysis of over 2000 patients de novo renal transplant demonstrated that EVR was associated with a decrease in and delay in the time of onset of CMV events compared to MPA. Our hypothesis is that basiliximab in combination with low dose tacrolimus, everolimus and prednisone may result in comparable efficacy (BCAR) observed in patients receiving tacrolimus/mycophenolate/prednisone but with a better safety profile (CMV infection) and cost-effectiveness.

Whether non-bismuth quadruple therapy (concomitant therapy) is more effective than bismuth quadruple therapy or triple therapy for 14 days remains unknown. Therefore, we aim to compare the eradication rates and long term re-infection rates of quadruple therapy for 10 days versus non-bismuth quadruple therapy for 10 days vs. triple therapy for 14 days. Methods: This will be a multi-center, open labeled, randomized control trial Patients: H. pylori infected patients who have willingness to receive eradication therapy Testing for H. pylori infection Before First Line Ttreatment (1)Any two positive of rapid urease test, histology, serology and culture or a positive UBT will be considered as H. pylori infected After First Line Treatment: C13-Urea breath test will be used to assess the existence of H. pylori 6-8 weeks after first line therapy. Long term reinfection: C13- Urea breath test will be used to assess the recurrence of H. pylori 1 year after eradication therapy

Epidemiological studies showed that 20-30% of patients with uncomplicated urinary tract infections risked recurrent infection. Urinary tract infection causes marked discomfort for the patient, has a negative impact upon quality of life, and is associated with high social and health costs in terms of specialist appointments, laboratory and instrumental tests and prescriptions . Although diverse cycles of antibiotic therapy and prophylaxis have been proposed, doubts persist about the most efficacious pharmacological agents, duration of prophylaxis , the incidence of adverse effects and relapse when antibiotic therapy is suspended. Aims of the study: To compare the efficacy of two prophylactic schedules (Prulifloxacin vs Phosphomycin): in reducing the number of urinary tract infection episodes during prophylaxis in reducing the number of urinary tract infection episodes after prophylaxis in improving the patient's quality of life . To assess : Tolerability of antibiotic prophylaxis The incidence of resistance to antibiotic therapy

Recent data have demonstrated beneficial health outcomes of microbiota transplantation for the treatment of Clostridium Difficile infection. The investigators propose testing whether fecal transplantation from a healthy donor can lead to a recovery from Clostridium Difficile recurrent/treatment-resistant infection.

The purpose of this study is to see if valacyclovir (Valtrex) is a safe and effective treatment for ano-genital HSV infections (herpes simplex virus infections of the anus and external genitals) in HIV-infected patients.

The number of patients requiring joint replacement is increasing due to its success in restoring function and pain relief, and the growing population of the elderly. One of the most serious complications of arthroplasty is joint prosthesis infection. Due to the absence of prospective, randomized, controlled studies, there is no consensus concerning diagnosis and treatment of prosthetic joint infections. The main objective of this trial is to evaluate the clinical efficacy of rifampin combination therapy versus monotherapy using cloxacillin or vancomycin in early staphylococcal infections after total hip and knee arthroplasty.

The purpose of this study is to find out more about cytomegalovirus (CMV) and how it is spread between people. One thousand adolescent males ages 12-17 years will participate in this study. Participants will be given a questionnaire about risk factors for CMV. A small blood sample (2-3 teaspoons) will be taken to test for CMV infection. Subjects that are CMV seronegative may participate in the second part of this study, which will involve returning to the clinic at regularly scheduled visit times to provide blood, urine, and saliva (spit) samples. This part of the study will take at least 24 months to complete. Subjects that test positive for CMV during the 2nd portion of the study will be invited to participate in the 3rd part of the study. This part of the study will require 8 regularly scheduled visits to provide blood, urine and saliva samples, over a 12-month period. The maximum amount of time a subject will participate in the study is 36 months.

Helicobacter pylori colonizes approximately to 50% of the world-wide population. There is an exigency to find routes alternating to control the infection with an ample perspective but without the complications of induction of resistance to antibiotics. Supplement dietetic with Lactobacillus reuteri (L. reuteri) in humans takes to the colonization of epithelium gastric and this, combined with the observation of which L. reuteri has the capacity to inhibit the growth of H. Pylori and its union to the gastric mucosa, indicates the potential that the native human bacteria control and influence in the colonization in humans. The acid-lactic bacteria (in particular the lactobacillus) have been studied by their effects in humans infected with H. Pylori with some success to reduce the load of bacteria Studies using supplements with L. reuteri as much in infected symptomatic patients as asymptomatic with H. pylori showed a clear reduction of the load of bacteria after 4 weeks of use and this was concordant with a reduction in the symptoms associated to the infection.

The overall aim is to validate the current use of FDG PET/CT for the diagnosis of infection and inflammation and examine the usefulness of PET/CT applying also other tracers. The results should allow us to confirm our primary hypothesis: "FDG-PET/CT is better than established methods to confirm or exclude the diagnosis of infection/inflammation".

The eradication rate of the standard H. pylori eradication therapy (such as the triple therapy with a proton pump inhibitor [PPI], amoxicillin and clarithromycin) depends on bacterial susceptibility to clarithromycin and genotypes of CYP2C19 in patients. The investigators intend to investigate whether the tailored therapy based on the two above-mentioned factors increases the cure rate of the initial eradication therapy.
