Filter by:The hallmark of HIV infection and AIDS is the continuous attrition of CD4 T cells. One of the mechanisms that may account for the CD4 attrition , is autoimmunity against the CD4 T cells, caused by autologous immune cells. Vaccination against autoimmune reactive T cells has been successfully tried in animal models of autoimmune diseases and is now being tried in patients with Multiple Sclerosis. The purpose of the present study is to test this hypothesis in HIV infection. We will vaccinate HIV infected patients in whom specific autoimmune reactivity against CD4 is present , with their own CD4 reactive T cells. Following that, we shall study the patients and find out if the T cell vaccination caused a rise in CD4 T cell levels, and whether it influenced HIV viral load, as well as HIV and CD4 specific immunity.
The purpose of this study is to test whether a U.S. Food and Drug Administration (FDA) approved laboratory test (PCT Kryptor) can help doctors make better decisions on the need for antibiotic therapy in ICU patients with suspected infections.
The impact of continuous veno-venous haemofiltration (CVVH) on sepsis-induced multiple organ failure severity is controversial. We thus sought to assess the effect of early application of haemofiltration on the degree of organ dysfunction and plasma cytokine levels in patients with severe sepsis or septic shock.
This study examines the cold processes of children aged 6 to less than 14. Children will be seen by the study staff 6 days in a row during the course of their naturally-acquired colds. Nasal secretions will be examined for chemicals that the body creates during a cold. Skin cells will be collected by brushing the inside of the child's cheek with a small brush. The cells will be examined for genes that may hold control the creation of these chemicals.
To assess the molecular epidemiology, clinical impact, treatment outcome and risk factors for infections caused by Enterobacteriaceae producing ESBLs in Italy in a large multicenter observational survey. SPECIFIC OBJECTIVES 1. To collect consecutive nonreplicate isolates of Enterobacteriaceae resistant to expanded-spectrum cephalosporins from clinical specimens from inpatients and outpatients. 2. To characterize the isolates for resistance phenotypes and for β-lactam resistance mechanisms. 3. To investigate the clonality of isolates. 4. To analyse the epidemiology of various resistance mechanisms/resistant clones. 5. To collect clinical and epidemiological data for patients with infections caused by the ESBL producers. 6. To analyse the epidemiology, risk factors and outcome for infections caused by ESBL producers.
To assess if a sequential treatment regimen better eradicates H. pylori than does a triple drug regimen in adults with dyspepsia or peptic ulcer disease.
Patients, who are considered suitable by their physicians to take part in this research, will have a physical examination (including an Electrocardiogram (ECG)), blood and urine samples taken, as well as a sample of the secretions or tissue around their infection site. In addition, the site of the infection will be photographed. The patients will be randomly assigned one of the treatments: intravenous (IV)/per oral (PO) moxifloxacin (drug under evaluation) or IV piperacillin/tazobactam followed by PO amoxicillin/clavulanic acid (i.e., one of the reference treatments for this kind of infection). The maximum treatment duration will be 21 days, and the minimum will be 7 days. During the hospitalization, the patients will have a physical examination every day. On Day 3-5 during therapy as well as at the end of treatment, the patients will have repeated examinations. These tests and evaluations will be repeated 14 to 28 days after the end of treatment. During this visit, blood and urine samples will be taken only if judged necessary by the physicians.
1. To study the efficacy of a therapeutic HIV vaccine consisting of autologous myeloid dendritic cells pulsed ex vivo with high doses of inactivated autologous HIV-1, in HIV-1 infected patients in a very early stages of the disease (CD4 > 450 x 10 6 /L). 2. To analyze the HIV-1 humoral and cellular immune responses induced by this immune-based therapy.
The purpose of this study is to investigate if treatment of CMV infection by antiviral drug Valcyte (R) affects the clinical outcome of glioblastoma multiforme in patients with local CMV infection in tumor tissue. The investigators' hypothesis states that CMV infection promotes tumor development and disease progression and inhibits immune responses against the tumor.
To investigate safety, tolerability and anti-viral activity in Integrase-Naïve HIV-1 infected adults
