Active clinical trials for "Infections"

Interleukin 29 (IL-29) is a substance that is produced in the body to help fight viral infections. The purpose of this study is to evaluate the safety and antiviral effects of several different doses of PEG-rIL-29 (a man-made form of IL-29) when it is given in combination with daily oral doses of ribavirin (an antiviral drug) to subjects with hepatitis C infection who have received no prior treatment for this disease.

The safety and tolerability of hLF 1-11 given in multiple doses has to be established first in HSCT recipients who are at risk of developing, but have not yet developed, infectious complications due to invasive fungal or bacterial disease. These patients are different from healthy volunteers because they have received myeloablative treatment, which not only arrests haematopoiesis resulting in neutropenia but also induces mucosal barrier injury both of which predispose to infections, which typically occur during the week after transplant. It is therefore essential to know that hLF 1-11 is safe and well tolerated when given during neutropenia and mucosal barrier injury before infections ensue.

The purpose of this study is to look at the safety and effectiveness of a pill called Trizivir that is a combination of three anti-HIV drugs (zidovudine, lamivudine, and abacavir). Zidovudine and lamivudine are often given combined in one pill (Combivir). In this study, Trizivir will be compared to Combivir plus abacavir.

This protocol offers diagnosis and standard medical treatment for various parasitic gastrointestinal infections. Gastrointestinal parasites are either worms (helminths) or one-celled animals called protozoans which live in the human intestines. Often, parasitic infections do not cause illness. In these cases, drug treatment is not indicated, because treatment can have adverse side effects. Patients will be examined for their immune responses, correlation between the number of parasites and disease, and other studies. Individuals with known or suspected parasitic diseases of the gastrointestinal tract, including amebiasis, giardiasis, hookworm, strongyloidiasis, trichuriasis, pinworm, tapeworm, trichinosis, clonorchis, opisthorchis, coccidiosis, paragonimiasis, and echinococcus may be eligible for this study. Patient evaluations may include blood and urine tests, stool examination, X-rays, ultrasound studies and, uncommonly, duodenal aspiration for examination of fluid from the duodenum (first part of the small intestine). Other tests may be required, depending on the parasite and disease. Direct examination of the tissues of the intestines may be required to rule out certain infections. Research procedures include collection of stool, blood and duodenal fluid when the diagnosis has been established and these procedures are not required for medical care. Patients with strongyloidiasis may also be given a diagnostic skin test similar to skin tests for tuberculosis and allergies. Research procedures on children will be limited to collection of stool, urine and blood. No more than 7 milliliters (1 1/2 teaspoons) per kilogram (2.2 pounds) body weight of blood will be collected in children over a 6-week period. In adults no more than 30 tablespoons of blood will be collected in a 6-week period. Parasites may fail to respond to treatment. In these cases, it may be necessary to grow the parasite in the laboratory in order to test treatments in the test tube. Patients who do not respond to standard medications and dosing may need different doses of drugs or drugs or combinations of drugs used in the United States for other medical problems. If these medications or doses are used, patients will be informed of their possible side effects.

In adult HIV-positive patients, data on the safety and immunogenicity of the quadrivalent HPV (qHPV) vaccine have been reported with excellent results (13 14); also, the results of a clinical trial of qHPV vaccine conducted in seropositive patients older than 36 years (WLHIV and MSM) have been published. Even now, there is not a trial about immunogenicity and safety of a 9-valent human papillomavirus vaccine in HIV-positive women; for this reason, the investigators plan to conduct this clinical trial. HYPOTHESYS: The administration of Nonavalent HPV vaccine (HPV-9) in adult women living with HIV will produce antibodies against nine genotypes of HPV, thus preventing the acquisition of new infections by those genotypes. Besides, this will prevent the cervical and anal dysplasia in these women.

Cytomegalovirus (CMV) infections is a severe infection in patients of rheumatic disease treated with corticosteroid and immunosuppressive agents. Ganciclovir is the main therapy in CMV infection, accompanied with diverse side effects, including neutropenia, anemia, disorder of renal function and so on, which are also common symptoms of rheumatic diseases. Additionally, prolonged antiviral treatment may delay recovery of virus, specific immune responses, resulting in an increasing of late-onset CMV disease. IL-2 is a pleotropic cytokine which can promote the proliferation and function of CD8+ T cells and NK cells through the combination with IL-2 receptor. Recently, several studies have revealed that low dose IL-2 is an effective and safe therapy for autoimmune disease. In systemic lupus erythematous patients, additionally, patients treated with low-dose IL-2 had lower incidence of infection with increased percentages of natural killer (NK) cells. In this prospective clinical trial, we propose to assess the effective and safety of low-dose IL-2 combined with ganciclovir in the treatment of CMV infection. Meanwhile, we will assess the immune response of after IL-2 treatment.

Aim: Therefore, we aimed to compare the efficacy of susceptibility testing guided therapy vs. empirical therapy in the third-line eradication for refractory H. pylori infection assess the long-term impact of eradication therapy on the antibiotic resistance and microbiota of the gut flora and the metabolic factors. Methods: This will be a multi-center, open labeled trial Patients: 360 patients with failure to H. pylori eradication for at least two times will be enrolled Determination of antibiotic resistance of H. pylori: Agar dilution test will be used to determine the minimum inhibitory concentrations of levofloxacin, tetracycline, rifabutin, and clarithromycin to guide the selection of antibiotics. Treatment regimens and assignment: Eligible patients will be randomized to receive either one of the treatments (A) Susceptibility testing guided therapy or (B) Empirical therapy Outcome Measurement: Primary End Point: Eradication rate will be evaluated according to Intent-to-treat (ITT) analyses. Secondary End Point: 1. Eradication rate according to per protocol analysis (PP analysis); 2. Frequency of adverse effects.

Helicobacter pylori infection causes active peptic ulcer disease and related complications like bleeding and pyloric obstruction. Usually, clinicians tended to treat Helicobacter pylori infection after active peptic ulcer disease and related complicaitons getting healed, which spent time and money. This study is designed to evaluate the efficacy and safety of intravenous administration of metronidazole, levofloxacin and esomeprazole triple therapy in the treatment of Helicobacter pylori infection combined with peptic ulcer disease related complications.

This is an open label randomised controlled study of oral ivermectin (600 mcg/kg/d* 3 day) versus combined of hydroxychloroquine plus darunavir/ ritonavir for 5 days treatment among asymptomatic carrier of SAR-CoV2 adult Thai population. Both study treatment regimens will have oral zinc sulfate combination treatment ( 200mg. twice daily). Outcomes include safety and duration of detectable of SAR-CoV2 in nasopharyngeal/ throat (NP) swab by polymerase chain reaction amplification (PCR) after treatment. 40-50 patients in each treatment arm is planned, with an interim analysis when approximately 50% of cases is enrolled.

The use of bilateral total knee replacements (TKR) is increasing with the number of patients with bilateral end-stage knee osteoarthritis. Bilateral TKR can be performed in three different ways: single-stage, two-team simultaneous bilateral TKR (two surgeons bilateral TKR); single-stage, a sequential bilateral TKR (single surgeon bilateral TKR); and two-stage bilateral TKR. Periprosthetic joint (PJI) infections are serious complications after TKR that negatively affect the aimed outcome, decrease patient satisfaction, and increase morbidity and mortality. The incidence of PJI is 1-2% and the number of cases is projected to grow as the indications for TKR continue to increase. Investigators will prospectively compare the incidence of periprosthetic joint infection between groups.
