Active clinical trials for "Infections"

Objectives: A recent randomized trial showed that 14-day sequential therapy containing high dose proton pump inhibitor was higher than 95% in the first line treatment. However, whether the 14-day sequential therapy is more effective than 10-day bismuth quadruple therapy remains unknown. Therefore, the investigators aimed to compare the eradication rates and long term re-infection rates of sequential therapy for 14 days versus bismuth quadruple therapy for 10 days in the second line treatment.

to assess the efficacy and safety of recombinant human interferon α-2b gel (Yallaferon®) for the treatment of patients with cervical HPV-16 and/or HPV-18 infections; to analyze the HPV type infections and clinical negative conversion.

This study is a Phase 2b/3, multi-center study designed to evaluate the efficacy, safety, and tolerability of the strategy of shifting clinically stable patients receiving suppressive combination antiretroviral therapy to PRO 140 monotherapy and maintaining viral suppression for 48 weeks following study entry. Consenting patients will be shifted from combination antiretroviral regimen to weekly PRO 140 monotherapy for 48 weeks during the Treatment Phase with the one week overlap of existing retroviral regimen and PRO 140 at the beginning of the study treatment and also one week overlap at the end of the treatment in subjects who do not experience virologic failure.

A new anti-HIV medicine (Dolutegravir) combined with 2 currently used anti-HIV medicines is non-inferior to the standard combination of medicines used in terms of efficacy and better in terms of toxicity.

Background: Tuberculosis (TB) is a severe disease and a major cause of death in many people worldwide. It is caused by a bacteria that enters through the lungs and can spread elsewhere in the body. People with latent TB have the bacteria that lie dormant but can become active and cause disease. These people are offered treatment to prevent development of active TB. Worldwide, a lot of people with LTBI also have a parasitic worm called a helminth that can stay in the gut or the blood. These parasites can affect the immune system and cause diseases like TB to become worse. Researchers want to see how helminth infection makes it harder for people to fight TB infection. Objectives: - To study how the immune system of people with latent tuberculosis infection (LTBI) acts to prevent development of active TB. Also, to study how helminth infection might affect this immune response. Eligibility: Adults age 18 70 with LTBI as defined by an approved blood test called QuantiFERON TB Gold. No evidence of infections like Hepatitis or HIV Pregnant subjects and subjects taking medications that suppress the immune system are not eligible. Have not received prior treatment for LTBI. Participants might be still eligible if prior treatment for active TB has been received Design: Screening phase: - Participants will be screened with medical history, physical exam, and blood tests for other infections/conditions which might affect the immune system. They will have testing for active TB i.e. blood testing as well as testing of their spit, scans and X-rays. Baseline phase: Only eligible participants will be entered into the study. Participants will have interviews, medical history, and physical exam. Blood will be drawn from an arm vein for testing. Participants will collect stool samples at home for 3 days in a row to test for helminth infection.. Participants may have apheresis. Blood cells are removed by needle. They pass through a separator machine which returns everything but the cells back to the participant. Participants may have procedures at the start and end of the study that let researchers look into the lungs and collect cells. Study phase, about 2 years: All participants will be offered treatment for LTBI which lasts 6-9 months. Participants being treated for LTBI will have about 11 study visits. They will visit monthly for 9 months while on treatment, then 6 and 12 months after treatment. Participants not eligible/refusing treatment for LTBI will be made aware of active TB, then have 3 other visits, about 6, 12, and 24 months after the baseline visit. Participants who have helminth infection will receive appropriate treatment. All participants will have blood drawn at each visit.

Objective To observe the safety and tolerability of Pazufloxacin Mesylate Ear Drops of different concentrations in patients with simple chronic suppurative otitis media.

The purpose of this study is to assess efficacy of a new 14-day sequential therapy for the rescue treatment of refractory Helicobacter pylori infection, and whether it is safe while maintaining an ideal eradication rates. The researchers also want to testify whether a double-dose rabeprazole has equal efficacy to double-dose esomeprazole to provide sufficient acid inhibition.

The clinical trial is designed as a phase II, crossover clinical trial. It will be carried out in healthy volunteers, who will receive two different antibiotic regimen based on ceftriaxone. One of the regimens had shown clinical effectiveness in this scenario, but it is not suitable for OPAT programs. In the other hand, a new treatment schema useful in OPAT programs is proposed, but there is still a lack of pharmacokinetic data to support it. The plasma drug concentrations will be measured in both cases, comparing the minimal drug concentration observed and the pharmacokinetic profiles of the two regimens.

The purpose of this study is to evaluate efficacy of a 14-day concomitant therapy for the third-line treatment of Helicobacter pylori infection, and whether it is safe while maintaining an ideal eradication rates.
