Active clinical trials for "Communicable Diseases"

This is a follow-up of a previous dose-ranging study aimed at investigating 2 doses of the trivalent inactivated split virion influenza vaccine when administered by intradermal route with that of the current pharmaceutical presentation administered by intramuscular route. Primary Objective: To assess the immunogenicity of two pharmaceutical presentations of the trivalent inactivated split virion influenza vaccine 21 days after a single injection in subjects aged 18 to 57 years. Secondary Objective: To evaluate the safety profile during the 21-day period following each vaccination in each study group

This is an open, randomized, multicenter clinical trial. Objectives: To describe the safety profiles during the 21 days following each primary and booster injection. To describe the immune response 21 days after each primary and booster injection of each formulation. To describe the antibody persistence after the first vaccination

As a result of the safety and immunogenicity data generated from earlier dose-ranging studies, the present formulation has been selected for further development in the elderly. Primary Objective: To compare the immunogenicity in subjects receiving investigational Fluzone with those of subjects receiving standard Fluzone®. Secondary Objectives: Immunogenicity: To describe the immunogenicity in subjects receiving investigational Fluzone and standard Fluzone®. Safety: To evaluate and describe the safety profile of investigational Fluzone in terms of solicited- and unsolicited adverse events and serious adverse events post-vaccination.

The purpose of this study is to determine whether the gentamicin-collagen sponge is safe and effective for preventing surgical wound infections in patients undergoing colorectal surgery.

The purpose of this program evaluation is to determine whether the Health Love Workshop, a group-level HIV behavioral intervention, reduces HIV-related sex risk behaviors and increases HIV protective behaviors of African American women and women of African descent. The intent of this program is to support an evaluation of the efficacy of the intervention and to provide feedback to the implementing organization to increase intervention effectiveness.

Subjects received HPV 16 L1 VLP vaccine or placebo (1:1 ratio). Endpoints included efficacy, immunogenicity, and safety.

Compared to young adults, the elderly mount a lower antibody response to vaccination. Thus, improvement of the immune response to influenza vaccination in this age group, which is at higher risk for influenza-related morbidity and mortality, represents an important unmet need. Primary Objectives: Immunogenicity: To demonstrate lot consistency of the Fluzone High Dose (Fluzone HD) manufacturing process through evaluation of the immune responses elicited by three different lots. To demonstrate the superiority of Fluzone HD vaccine compared to standard-dose Fluzone® vaccine. Secondary Objectives: Immunogenicity: To describe the seroprotection of Fluzone HD compared to that of standard dose Fluzone® vaccine. Safety: To describe the safety profile of Fluzone HD, in terms of solicited -, unsolicited adverse and serious adverse events post-vaccination. To describe clinical information on some additional defined criteria during the six months following vaccination.

The purpose of this study is to investigate the frequency of urinary tract infections with symptoms in spinal cord injured patients requiring intermittent catheterization for emptying the bladder. Patients will use either a coated catheter or an uncoated catheter with gel.

Acute respiratory tract infections (ARTI) are among the most frequent reasons for seeking medical attention in primary care. Although from predominantly viral origin, ARTIs are the most important condition for the prescription of antibiotics (AB), mainly due to the difficulty in primary care to differentiate between viral and bacterial etiology. Unnecessary AB use increases drug expenditures, side effects and AB resistance. A novel approach is to guide AB use by procalcitonin (ProCT), since serum levels are elevated in bacterial infections but remain lower in viral infections and inflammatory diseases. We aim to compare a strategy based on evidence-based guidelines with ProCT guided AB therapy in ARTIs with respect to outcome (days with restriction) and AB use. Patients presenting with ARTIs to primary care physicians and are intended to be treated with AB based on guidelines will be included and randomized 1:1 either to standard management or to the ProCT guided prescription of AB. All participating physicians will receive evidence-based guidelines for the management of patients with ARTIs. Patients with ARTI and in need of ABs by physicians' clinical judgment and with informed consent will be randomized to ProCT plus guidelines ("ProCT group") versus only guidelines guided AB treatment ("control group"). In patients randomized to the ProCT group, the use of antibiotics will be more or less discouraged (<0.1 or <0.25 ug/L) or encouraged (>0.5 or >0.25 ug/L), respectively. A re-evaluation in patients with ProCT (<0.1 or <0.25 ug/L) after 6 to 24 hours is mandatory. All patients will be reassessed at day 3 and it is recommended to stop AB in the ProCT group as described above. Structured phone interviews at days 14 and 28 will be done in all patients from both groups.

The majority of HIV infected people worldwide became infected with the virus through heterosexual contact. BufferGel and PRO 2000 Gel are vaginal gels designed to prevent women from becoming infected with HIV during sexual intercourse with an HIV infected partner. This study will test the safety and effectiveness of these gels.
