Active clinical trials for "Infections"

The aim of this study is to assess the efficacy of lopinavir/r in monotherapy and peg-interferon plus ribavirin for the control of both HIV and HCV infection respectively after 12 months of active treatment for HCV.

Upper respiratory tract infections (URTIs) are the most common illnesses in primary medical services but there is no established cure for these conditions in Western medicine. In Hong Kong, many patients use Chinese herbal medicine (CHM) for the treatment of URTIs but there is little research evidence on their effectiveness or side effects. The aim of this study is to test whether two commonly used Chinese herbal medicine (CHM) formulae guided by Traditional Chinese medicine (TCM) diagnosis will significantly increase recovery rate, and reduce the duration and/or severity of symptoms, and improve the quality of life of patients with URTIs in primary care. If a patient consents to take part in the study and is found eligible, he/she will be invited by the consulting doctor, and then be assessed by a registered Chinese medicine practitioner for whether the illness satisfies the TCM diagnosis of the two major TCM types of URTIs: Group A (Wind-cold syndrome) and Group B (Wind-heat syndrome). Subjects in Group A (Wind-cold syndrome) will be randomised to receive the Jing Fan Bai Du san or placebo. Subjects in Group B (Wind-heat syndrome) will be randomised to receive Ying Qiao san or placebo. Both group A and B treatments and placebo will be given in sachets of granules that are identical in appearance. Neither the Chinese medicine practitioner, the recruiting doctors, nor patient know whether a subject is taking CHM or placebo. 328 subjects (164 in each diagnosis group) will be recruited from patients consulting the Ap Lei Chau Government General Outpatient clinic for URTIs. Each subject is required to return to the clinic for follow-up assessment by the Chinese medicine practitioner on day 7 post-treatment and all subjects will be contacted by telephone on Day 2, 3, 5, 9, 11, 13,15 and 20 after treatment to assess their symptoms and to find out if they have developed any side effects or adverse reactions. The main outcome measure is any difference in the proportion of subjects who have resolution of the URTI on Day 7 between the treatment and placebo groups. The secondary outcome measures are the reduction in the duration and severity of symptoms, quality of life during the illness and side effects. This study will provide scientific evidence to support or refute the effectiveness of two commonly used CHM formulae in the treatment of URTIs.

The purposes of this study are: To understand whether the use of HIV therapy in persons with more advanced HIV disease results in greater side effects. To determine whether these side effects can be related to greater activation of the immune system.

A phase Ib partially blinded pilot study to evaluate the safety and immunological effects of PENNVAX-B with or without co-administration of constructs containing DNA encoding for the expression of either IL-12 or IL-15. Primary objectives To determine the safety of HIV-1 DNA constructs (PENNVAX-B). To determine the safety and optimal doses of the IL-12 and the IL-15 adjuvant constructs when given with PENNVAX-B. Secondary objectives To compare the various vaccine groups for their immunological responses to several HIV-1 antigens, utilizing the ELISPOT assay. To analyze antibody responses to the vaccine antigens over time. To measure CD8 cell proliferative responses to vaccine antigens over time.

To evaluate the single dose relative bioavailability of GSK1265744 10mg administered in either oral solution fasted, two 5mg tablets fasted, or two 5mg tablets following a moderate meal.

This a phase 2, randomized, open-label trial of GS-9256 plus GS-9190, two oral anti HCV drugs, for 28 days with and without ribavirin (RIBA) and with pegylated interferon (PEG)/RIBA in adults with chronic Hepatitis C virus (HCV). In Part A, approximately thirty (30) subjects 18-70 years of age who meet study entry criteria will be randomized (in other words, selected at random, like flipping a coin) to one of the two treatment groups (GS-9256 plus GS-9190 or GS-9256 plus GS-9190 plus RIBA). In Part B, an additional fifteen (15) subjects will receive 75 mg GS-9256 BID plus 40 mg GS-9190 BID in combination with PEG/RIBA. After the 28-day treatment period, subjects will receive PEG/RIBA as standard of care (SOC). Following randomization, subjects will return for a Baseline (Day 1) visit, at which time study medication will be dispensed and subjects will enter a 28 day treatment phase. During the treatment phase, subjects will receive oral study drugs twice daily for 28 days and PEG once weekly for Part B. Subjects then receive PEG/RIBA as local SOC starting on Day 28 (not provided as part of the study). Following completion of the 28-day treatment phase, subjects will be followed for approximately 72 weeks.

The primary purpose of this study is to determine if adding bleach baths to routine ways for prevention of Staph infections is helpful. The amount added is a very weak amount. This would provide a relatively inexpensive method to help prevent recurrent skin infections caused by the Staph germ. The investigators will also be studying how often Staphylococcus aureus lives in the nose, throat, and groin area.

This is a research study to see whether fat accumulation either under the skin or in the body's organs, for example, the liver, improves in men and women who take a drug called telmisartan. The investigators will be looking at how the amount of fat in the body changes when HIV-positive persons on effective anti-HIV therapy take telmisartan. The investigators will be using a CT scan to make this comparison. Telmisartan is not an HIV medication. It is a medication used to treat blood pressure, but has been shown to decrease fat in the organs in people both with and without high blood pressure. The study involves 8 visits over a period of about 24 weeks.

The aim of this study is to determine the efficacy and safety of once daily topical application of the combinational cream LAS41003 compared to the corresponding mono-substances in the treatment of candida infections in intertriginous areas at the trunk.

Background: Helicobacter pylori infection has been shown to be associated with the development of gastric cancer and peptic ulcer diseases. Eradication of H. pylori infection could reduce the occurence or recurrence of these diseases. However, it was estimated that 15-20% of patients would fail from first line standard eradication therapy and need second line rescue therapy. About 15-30% of patient would fail from second line therapy and need to be rescued with third line therapy. The commonly used salvage regimens include (1) Bismuth based quadruple therapy (combined with ranitidine or PPI plus two antibiotics) (2) Levofloxacin or moxifloxacin or rifabutin based triple therapy. However, Bismuth is not available in many countries and the administration method is complex. Its usage is limited by the high pill number and low compliance rate. In recent years, the concept of sequential therapy has been advocated in the treatment of H. pylori infection. The regimen includes a PPI plus amoxicillin for five days, followed by a PPI plus clarithromycin and metronidazole for another five days. The eradication rate in the first line treatment of sequential therapy had been reported to be as high as 90%. More importantly, it has been demonstrated that the eradication rate among patients with clarithromycin-resistant strains could be as high as 89%. According to the Maastricht III consensus meeting, it was recommended that susceptibility test should be done for patients who failed two treatments. Therefore, we aimed to assess the efficacy of susceptibility test driven sequential therapy as the third line therapy for those who fail from two standard eradication therapies. Methods: This will be a multi-center, open labeled pilot study Patients: Open labeled, non-comparative pilot study Testing for H. pylori infection: Before salvage treatment: either (1) any two positive of CLO test, histology, and culture or (2) a positive C13-UBT will be considered as failure of previous eradication treatment EGD with gastric biopsy will be done for H. pylori culture and susceptibility test After salvage treatment: C13-UBT will be used to assess the existence of H. pylori after 2nd or 3rd line salvage therapy Treatment regimens and assignment: D1-7: Nexium (40 mg, bid), Amolin (1 gm, bid) D8-14: Nexium (40 mg, bid), Flagyl (500 mg, bid) plus either one of the following according to antibiotic susceptibility test (1) Klaricid, 500 mg, bid or (2) Cravit, 250 mg, bid or (3) Tetracycline, 500 mg, bid Outcome Measurement: Primary End Point: Eradication rate will be evaluated according to Intent-to-treat (ITT) and per-protocol (PP) analyses Secondary End Point: the eradication rate according to antibiotic susceptibility before salvage therapy
