Filter by:The approach we will use is to employ measurement of the activation of white blood cells, to look at patterns of responses during a controlled infection of the gut with Mycobacterium bovis. M. bovis can be conveniently obtained in a safe and pure form as an oral vaccine. By giving three challenges of M bovis to the gut, we will simulate repeated gut infections with this organism. We can then compare the activation of cells in the blood to the immune responses seen after each challenge, to determine whether the non-specific defences of the gut can block each subsequent infection.
To assess protection against early life infections through supplementation of mothers during pregnancy to the newborns' growth, morbidity, immune status intra and extra-uterine.
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.
Iron deficiency is considered one of the main nutritional deficiency disorders despite the apparent availability of a high-quality diet even in developed countries, and Iron deficiency anemia (IDA) is the most common form of anemia in the world. IDA during pregnancy has been associated with adverse health consequences for both the mother and her developing fetus. Helicobacter pylori (Hp) may be the most common bacterial infection worldwide, infecting almost half of people in developed countries and 80% of people in developing countries. The available data on the prevalence of Hp infection in Taiwan population was 54.4%. We all know that infection with Hp is strongly associated with peptic ulcer and gastric cancer, but recent evidence suggests that Hp is associated with iron deficiency and anemia, although the mechanisms remain unclear. Till now, only few previous studies specifically have addressed a potential role of Hp infection on anemia or iron deficiency during pregnancy. Our previous Research showed, between the Hp infection (+) and Hp infection (-) gravidas, the associations between the Hp infection and iron deficiency were stronger, although not statistically significant. This might be due to that we needed more cases and evidences to prove the relationship between maternal Hp infection and serum iron, ferritin and hemoglobin levels, or we should further consider the interactions of the particular customs or diet preference of the Taiwanese gravidas. This longitudinal study will recruit 140 women from the antenatal care clinics of E-Da Hospital to examine the association between Hp infection and maternal IDA. The standardized interviews of mothers (anthropometric data, socioeconomic status, medical history, obstetric history, alcohol consumption during pregnancy, and history and duration of iron supplementation during pregnancy) will be conducted, Hp infection status will be determined by the urea breath test and IgG enzyme immunoassay, and the measurement of hemoglobin, iron, and ferritin levels will be obtained 5 times at various antepartum and postpartum points of time during pregnancy (routine prenatal visits of 1st, 2nd, and 3rd trimester, puerperium and 2 weeks after delivery). We hope that we could investigate the possible role of Hp infection in iron deficiency and iron-deficiency anemia during pregnancy in Taiwan, and that early detection and treatment of anemia may reduce the risk of blood transfusion and perinatal and maternal mortality.
Patient's on this protocol have a type of blood cell cancer, other blood disease or a genetic disease and have received a stem cell transplant. The donor of the stem cells was either a brother or sister, another relative, or a closely matched unrelated donor. The patient is being asked to participate in this study which tests if blood cells from the donor that have been grown in a special way, can prevent or be an effective treatment for early infection by three viruses - Epstein Barr virus (EBV), cytomegalovirus (CMV) and adenovirus. Adenovirus is a virus that usually causes symptoms of a common cold, but can cause serious life-threatening infections in patients who have weak immune systems. It can affect the lungs and cause very serious pneumonia, and can also damage the gut, liver, pancreas and eyes.CMV can also cause serious infections in patients with weak or suppressed immune systems. It usually affects the lungs, causing a very serious pneumonia, but it can also affect the gut, the liver and the eyes. Approximately 2/3 of normal people harbor this virus in their body. In healthy people CMV rarely causes any problems because the immune system can keep it under control, but after a transplant, the risk of developing CMV disease is much higher because the immune system is so weak. EBV is the virus that causes glandular fever. It is also a life long infection like CMV that is normally controlled by the immune system. When immunity is weak, the virus can become active and cause fevers, enlarged lymph nodes and sometimes a type of cancer called lymphoma. Investigators want to see if a kind of white blood cell called T lymphocytes (T cells)can be used to prevent and treat adenovirus, CMV and EBV in the early stages of reactivation or infection. T cells have been grown from the patient's stem cell donor in the laboratory in a way that will train them to recognize the virus and control it when they are given after a transplant. This treatment with specially trained T cells (also called CTLs) has had activity against these viruses in previous studies and in this study investigators want to see if they still have activity when they are made in a simpler and faster way. These donor-derived multivirus-specific special cell lines are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to evaluate whether donor-derived multivirus-specific special cell lines are safe and can control three viruses: EBV, CMV and adenovirus.
The primary focus of the study is the evaluation of the safety of treatment with moxifloxacin in a pediatric population 3 months to <18 years old. Approximately 450 pediatric subjects with a complicated intra-abdominal infection will be enrolled in the study and treated with either moxifloxacin intravenously and orally if switched to oral therapy or ertapenem (intravenously) and, if switched to oral therapy, amoxicillin/clavulanate.
Purpose: The study null hypothesis is that vitamin D supplementation will not influence time to acute respiratory tract infection in sheltered accommodation residents.
STUDY HYPOTHESIS : An infection prevention program adapted for the nursing home context can reduce by 5% the number of infections (urinary, upper and lower respiratory and gastrointestinal) in elderly residents in nursing homes. STUDY DESIGN : The proposal is for an interventional cluster (nursing home) study comprising 2 randomized groups: group 1 (interventional), comprising 25 nursing homes implementing a specific infection prevention program; and group 2 (control), 25 nursing homes continuing to implement their routine prevention measures.
The purpose of this trial is to investigate whether irrigation solution (soap vs. saline solution), or irrigation pressure (high vs. low) will decrease the rate of infection among patients with open fracture wounds.
The purpose of this study is to determine whether there is a drug interaction between GSK1349572 and the HIV protease inhibitors Tipranavir/Ritonavir (TPV/RTV).
