Active clinical trials for "Infections"

This randomized controlled trial evaluates the efficacy of couples HIV testing and counseling retesting. Eligible couples previously enrolled in NCT05000866 are invited to participate. Those who do are randomized to either couples HIV testing and counseling (CHTC) retesting or an individual HIV testing control. Follow-ups occur 3 and 6 months post intervention.

The goal of this interventional study is to evaluate the pharmacokinetics, safety, and tolerability of 101-PGC-005 in healthy, adult, human subjects. The main question it aims to answer is what are the single and multi-dose PK properties of 101-PGC-005 in the systemic circulation Participants will receive a bolus injection of 101-PGC-005 administered intravenously once daily for 3 consecutive days. Blood and urine samples will be collected at predetermined timepoints for analysis.

Emergence of antibiotic resistance (AMR) is a serious concern for Low and Middle Income Countries (LMICs). Unregulated use of antibiotics, a major AMR driver, is highly prevalent in LMICs, with medicine stores as key providers. Physical interactions between One Health compartments increase cross-domain transmission risks, although the relative importance of different reservoirs is uncertain, with community-level dynamics of AMR in LMICs largely unquantified. In two rural health districts in Burkina Faso and DR Congo, a behavioural intervention bundle will be developed, targeting medicine stores and their communities, to optimise antibiotic use and improve hygiene, and hence reduce AMR prevalence and transmission. After a 6-month local co-development phase, the intervention will be implemented over 12 months and evaluated through a comparison between intervention and control clusters, consisting of one or more villages or neighbourhoods largely seeking healthcare with the same provider(s). The primary outcome measure is the change in Watch antibiotic provision from medicine stores (where a formal prescription is not required), assessed via patient exit interviews and simulated client visits. Changes in hygiene practices and AMR pathogen and gene carriage will be assessed in repeated population surveys. Rodents, living in close proximity to humans in much of sub-Sahara Africa, provide a proxy estimate of environmental AMR pathogen and gene exposure. Using modelling and sequencing of selected isolates, impact of AMR transmission by changes in antibiotic use and hygiene practices will be quantified.

The study was done to: Start antiretroviral therapy (ART) early in those recently or acutely infected with HIV-1 See how starting ART as soon as the infection is found affects the amount of HIV-1 in blood and how well the body fights the HIV-1 infection Look at the amount of HIV-1 DNA (genetic material for HIV-1) seen in CD4+ T-cells (infection-fighting cells in blood) after 48 weeks of ART See how early treatment for HIV affects the numbers of HIV-1 infection fighting cells (CD4+ and CD8+ T-cells) in blood

The primary purpose of the study is to evaluate whether most closely HLA-matched multivirus-specific T cell lines obtained from a bank of allogeneic virus-specific T cell lines (VSTs) have antiviral activity against three viruses: EBV, CMV and adenovirus. Reconstitution of anti-viral immunity by donor-derived VSTs has shown promise in preventing and treating infections associated with CMV, EBV and adenovirus post-transplant. However, the time taken to prepare patient-specific products and lack of virus-specific memory T cells in cord blood and seronegative donors, limits their value. An alternative is to use banked partially HLA-matched allogeneic VSTs. A prior phase II study at our institution using trivirus-specific VSTs generated using monocytes and EBV-transformed B cells gene-modified with a clinical grade adenoviral vector expressing CMV-pp65 to activate and expand specific T cells showed the feasibility, safety and activity of this approach for the treatment of refractory CMV, EBV and Adenovirus infections. However, the production process was lengthy, requiring 8-12 weeks, with exposure to biohazards (B95.8 EBV viral strain and adenovector), while antigenic competition between different viral components precluded increasing the spectrum of specificity beyond these three viruses. Investigator have overcome these limitations and in the current trial, they will evaluate whether rapidly generated, allogeneic most closely HLA-matched multivirus-specific VSTs, activated using overlapping peptide libraries spanning immunogenic antigens from CMV, adenovirus and EBV will be safe and produce anti-viral effects in allogeneic HSCT recipients infected with one of more of the targeted viruses that are persistent despite conventional anti-viral therapy. The study agent will be assessed for safety (stopping rules defined) and antiviral activity.

Cystectomy with urinary diversion (ileal conduit, orthotopic ileal bladder substitute, continent catheterizable pouch) is the best treatment option for patients with muscle-invasive bladder cancer. This intervention is one of the most challenging in urology and has a high rate of postoperative complications including around 30% of postoperative infections. Perioperative antibiotic prophylaxis (PAP) is widely accepted as a crucial preventive measure to reduce the incidence of surgical site infections (SSI). The rationale for PAP is the reduction of the local bacterial load at the site and time of intervention, and therefore a short duration of PAP of 24 to maximal 48 hours is recommended for all clean to clean-contaminated procedures.. Evidence supporting the optimal duration of PAP for radical cystectomy with urinary diversion is lacking. Based on data extrapolated from abdominal surgery, current guidelines recommend short-term PAP (≤24h) for all clean-contaminated procedures including radical cystectomy. However, a recent evaluation revealed a significant inter-hospital variability of PAP and showed that extended use (>48h) was common in patients undergoing radical cystectomy. Importantly, this study also demonstrated that longer duration of PAP incurred higher costs and was associated with an increased rate of C. difficile colitis. A small, prospective, non-randomized study showed equal efficacy of short-term PAP in preventing postoperative infections in patients undergoing radical cystectomy with ileum conduit compared to extended PAP. Nonetheless, larger randomized clinical trials supporting these findings are lacking. The unwarranted extended use of antibiotics is a major concern as exposure to antibiotics is a driving force for the development of (multi-) resistant bacteria and will lead to an increasing number of difficult-to-treat infections. This has been recognized on both national and international levels and is addressed within antimicrobial stewardship frameworks. This study will compare current practice (>48h PAP, "extended PAP") with the guideline recommended approach (24h PAP, "short term PAP") in a single-centre, prospective, randomised clinical non-inferiority trial. The primary outcome is the rate of SSI within 90 days post surgery. The aim of the study is to generate currently lacking evidence allowing for an optimised PAP strategy in a challenging surgical setting.

The purpose of this study is to identify and provide immediate antiretroviral therapy to a cohort of HIV-infected individuals with very early HIV infection (estimated date of infection within the last 90 days). The primary aim of the study is to evaluate whether initiation of dolutegravir plus emtricitabine/tenofovir during acute/early HIV infection leads to protection of CD4+ T cells and other immune cells in the peripheral blood and lymphoid tissue from infection.

endTB-Q Clinical Trial is a Phase III, randomized, controlled, open-label, non-inferiority, multi-country trial evaluating the efficacy and safety of two new, all-oral, shortened regimens for multidrug-resistant tuberculosis (MDR-TB) with fluoroquinolone resistance.

A Comparative Study of Autologous CD4+ T Cells Genetically Modified at the CCR5 Gene by Zinc Finger Nucleases SB-728 versus ex vivo Expanded Unmodified Autologous CD4+ T Cells in Treated HIV-1 Infected Subjects

Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract of unknown etiology. UC is characterized by recurring episodes of inflammation limited to mucosal and submucosal layers of the colon. The object of the present study was to determine the prevalence of intestinal protozoa and helminthes in UC patients, and the role of this changes in aetiopathogenesis of diseases. Patients will be examined before and after therapy. Parasites and protozoa prevalence and intensity will be detected by triple coproscopy.Microbiological study will be conducted before therapy for detection pathogenic bacteria only from UC patients infected with B. hominis . If intestinal pathogenic bacteria are found, participants will be excluded from further investigation.
