Filter by:The purpose of this study is to determine the pharmacokinetic profiles of LP-001, an amoxicillin and clavulanate formulation, for use in pediatric patients with a bacterial infection.
Background: People with HIV usually take a combination of 2 or more anti-HIV drugs daily to help manage their infection. Sometimes, however, HIV becomes resistant to these drugs, and the infection cannot be treated. Untreated HIV infection can make people more vulnerable to other infections as well as some cancers. Better treatments are needed for people with drug-resistant HIV. Objective: To see if a study drug (UB-421) is effective in people with drug-resistant HIV. Eligibility: People aged 18 years and older with HIV that is resistant to anti-HIV drugs. Design: Participants will be in the study for 35 weeks. Participants will have separate screening and baseline visits within 2 months of each other. They will have a physical exam with blood and urine tests both times. On the second visit, they will undergo apheresis: Blood will be drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in the other arm. Participants will begin receiving the study drug 1 week after their baseline visit. UB-421 is given through a tube attached to a needle placed in a vein in the arm. They will return for UB-421 treatments every week for 26 weeks. Each visit will take 3 to 6 hours. Participants will have 2 follow-up visits 4 and 8 weeks after their last treatment with UB-421. Apheresis will be repeated at 1 of these visits.
This study is a prospective, multicentric, observational test negative design study on adults hospitalized for Severe Acute Respiratory Infection (SARI), regardless of their vaccination status.
The main objective of the study will be to assess the performance of the Next-Generation-Sequencing (NGS) diagnostics of Chlamydia trachomatis and Neisseria gonorrhoeae compared to reference techniques.
Fecal microbial transplantation is to transplant functional microbiota from the feces of healthy people into the gastrointestinal tract of patients, reconstruct new intestinal microbiota, and realize the treatment of intestinal and extra-intestinal diseases. Compared with ordinary commercial probiotics, FMT is more consistent with the composition of the intestinal microecological structure and can recover intestinal flora to the maximum extent and faster. FMT increases intestinal bacteria production function and helps to restore the systemic immune response so that sepsis pathogens are removed. The aim of this trial was to investigate the clinical effect of FMT in the treatment of patients with severe infections.
This study evaluates the efficacy of a single strain probiotic on the incidence, duration and severity of upper respiratory tract infections in healthy, school-age children.
The objective of the study is to evaluate the efficacy of minocycline for treatment Stenotrophomonas maltophilia infection. The hypothesis of study is the combination therapy with minocycline would be better than the monotherapy for treatment Stenotrophomonas maltophilia infection.
Menopausal women have an increased risk of recurrent urinary tract infections. This is likely due in part to hormonal changes occurring during menopause. As estrogen falls, the vaginal microbiome shifts from a healthy one to a less healthy one. Because the vagina is close to the urethra, this vaginal microbiome shift contributes to a loss of protection against urinary tract infections (UTIs). The investigators are asking whether improving the vaginal microbiome using an over-the-counter vaginal hygiene system can reduce frequency of recurrent UTI in menopausal women.
We hypothesize that a high CD4+ and CD8+ T cell count will reduce viremia upon challenge with a structurally heterologous virus, and correspondingly result in reduced magnitude of host response to challenge infection. Primary Objective: To compare, after challenge with a structurally heterologous vaccine, the differences in levels of viremia between healthy adults who received primary vaccination with either YF17D vaccine, chimeric JE-YF17D vaccine, or inactivated JE vaccine. 58 subjects will be randomised into 1 of 2 arms (Arm B1 and Arm B2) in a 1:1 ratio, in a double-blind fashion. Subjects in Arm B1 will receive JE-YF17D vaccine (Imojev, Sanofi Pasteur) on Day 0 followed by YF17D vaccine (Stamaril, Sanofi Pasteur) on Day 28. Subjects in Arm B2 will receive Stamaril on Day 0 followed by Imojev on Day 28. Arm B3 will be conducted as a separate single-arm open label design in 14 subjects. Subjects in Arm B3 will receive inactivated JE vaccine (Ixiaro, Valneva) on Day 0 followed by Stamaril on Day 28. The rationale for these three study arms is as follows: Arm B1 will show the impact low levels of viremia, and the resultant low levels of virus-specific CD4+ and CD8+ T cells, would have on YF17D infection. In contrast, YF17D vaccination in Arm B2 would produce high levels of viremia, and in turn high levels virus-specific T cells, thus likely ameliorating JE-YF17D infection. Arm B3 will serve as the control arm, as vaccination with inactivated JE vaccine would not produce any YF17D-specific T cell response. Notably, the first vaccination in Arms B1 and B2 would also provide the viremia response in the absence of virus-specific T cells, which would serve as a reference point to interpret the outcome of the second vaccination.
Nosocomial Infections (NI) are a common and dreadful complication for patients suffering from Acute Respiratory Distress Syndrome (ARDS) treated with Extracorporeal Membrane Oxygenation (ECMO). Unfortunately, no study has thoroughly evaluated NI in this fragile patient cohort. Newly developed antibiotics may help manage such infections, but their pharmacokinetics (PK) during ECMO has not been evaluated. Objectives of this prospective observational multicenter pharmacological no-profit study are: 1) describe incidence, microbial etiology, and resistance patterns, and assess risk factors for NIs in a large prospective cohort of ARDS patients undergoing ECMO. 2) provide a PK analysis of ceftazidime/avibactam, meropenem/vaborbactam, ceftolozane/tazobactam, and cefiderocol in adult patients undergoing ECMO Incidence, microbial etiology, and antibiotic resistance patterns of confirmed NIs will be prospectively collected and analyzed. In the subgroup of patients treated with ceftazidime/avibactam, meropenem/vaborbactam, ceftolozane/tazobactam, or cefiderocol as per clinical practice, blood and bronchoalveolar concentration of the antibiotic will be measured, and PK modeling carried out.
