Active clinical trials for "Infections"

Invasive fungal infections (IFI) remain the major cause of death among neutropenic patients receiving chemotherapy for leukemia, or submitted to stem cell transplantation. Patients with a history of invasive fungal infection (IFI) are at high risk of developing relapse and fatal complications. Prompt intensive antifungal therapy, have improved responses and survival, allowing an increase of antifungal treatments, including secondary antifungal prophylaxis. Few studies have addressed the role of previous IFI in the feasibility of stem cell transplant, or the secondary prophylaxis with antifungal drugs in preventing recurrence of infection after transplantation. However, given the lack of prospective studies, the role of secondary antifungal prophylaxis remains unclear. Itraconazole is a wide-spectrum triazole antifungal agent active against Candida albicans, non-albicans, Aspergillus spp., Blastomyces dermatitidis, Blastomyces coccidioides, Cryptococcus neoformans, Sporothrix schenkii, Paracoccidioides brasiliensis, Histoplasma spp. and various kinds of yeast fungi and mycetes. The role of itraconazole IFI prophylaxis treatment has been proved by many interventional studies. In this prospective, multicentric study of secondary prophylaxis, itraconazole will be given at standard dose to patients undergoing allogeneic stem cell transplantation or chemotherapy with prior invasive fungal infection, to assess the efficacy and safety of itraconazole secondary prophylaxis.

This study will further evaluate the ACAM-CDIFF™ vaccine in a population of middle-aged to elderly individuals at risk of exposure to Clostridium difficile because of impending hospitalization or residence in a care facility. Primary Objectives: To describe the safety profile of subjects in each of the study groups. To describe the immune responses elicited by toxoid A and toxoid B of subjects in each of the study groups. Observational Objective: To describe the occurrence of first-time Clostridium difficile infection (CDI) episodes.

In recent years, influenza viruses that have traditionally infected animals have infected humans as well. The H2N3 influenza virus, which first appeared in pigs in the Midwest United States in 2006, may pose a potential health concern to humans. This study will evaluate the safety of and immune response to a vaccine designed to protect people from the H2N3 influenza virus.

The objectives of this study are: (1) to evaluate the safety and tolerability of VP 20621 dosed orally for up to 14 days in adults previously treated for CDI; (2) to characterize the frequency and duration of stool colonization with the VP 20621 strain of C. difficile; (3) to evaluate the efficacy of VP 20621 for prevention of recurrence of CDI; and (4)to select a dose regimen of VP 20621 to be used in future studies.

The study compared the magnitude of the antibody response and safety of a GBS Trivalent Vaccine in HIV positive and HIV negative pregnant women and their offspring. In addition the study investigated the maternal to fetal transfer of antibodies induced by the investigational vaccine.

In this study the investigators will determine whether corticosteroids given at the time of urinary tract infection help prevent permanent damage to the kidneys.

The purpose of this study is to compare the incidence of opportunistic infections between HIV-infected patients who continue and discontinue primary or secondary prophylaxis for opportunistic infections in whom receiving combination antiretroviral therapy and achieve undetectable HIV-1 RNA, but CD4 cell counts are less than 200 cells/mm3.

This is a study of patients undergoing gynecologic surgery who require post-operative catheterization to determine if prophylactic antibiotic treatment decreases the risk of post-operative urinary tract infection in these patients.

Men who have sex with men (MSM) have an increased risk of developing anal human papillomavirus (HPV) infections, which can be a risk factor for anal cancer. HIV-infected women are also at risk of anal cancer. This study will evaluate the effectiveness of the Food and Drug Administration (FDA)-approved quadrivalent HPV vaccine, Gardasil, at preventing anal HPV infection in HIV-infected MSM and HIV-infected women.

This is a single center, observational study of posaconazole PK sampling in lung transplant recipients. The patients enrolled will have up to 6 (3ml) pk samples (a total of 18 ml) and one 10ml blood sample for a total collection of 28ml of blood obtained over the entire study. In addition, the investigators will collect medical record information and any excess BAL samples available during the study (tests done as part of the patient's clinical care and the samples would have been discarded once diagnosis was made).
