Filter by:The study is an observational blinded Validation study in pediatric patients below 3 years old with a diagnosis of Fever Without Source (FWS). In this study the investigators aim to validate the performance of a proteomic signature aiding the physicians to discriminate between viral and bacterial infections in febrile children. The study will also assess the prevalence of Human Enteroviruses (HEV), Human Parechoviruses (HPeV), Adenovirus (AdV) and Human Herpesvirus type 6 (HHV-6) viremia, as well as Kingella Kingae bacteremia in the study cohort.
BK virus nephropathy (BKVN), a consequence of the strong immunosuppressive therapy given after kidney transplantation, represents a growing problem in the kidney transplant (KT) setting. In recent cohorts, BKVN concerns up to 10% of kidney transplant recipients and early signs of BK virus (BKV) infection as development of asymptomatic viruria and viremia are even much more frequent (40% and 20% of patients, respectively). In this context, finding strategies to prevent BKV infection or treat patients before the occurrence of BKV nephropathy is challenging. For several years, detection of BKV replication by real-time PCR in urine and/or blood of kidney transplant recipients at early stages of infection allowed adaptation of their therapy. As BKV reactivates essentially in patients with over-immunosuppression, the first step of the treatment is the reduction of immunosuppression. However, reducing immunosuppression (IS) can lead to acute rejection and allograft loss. Other treatments have been proposed (cidofovir, quinolones) but their toxicity profile or their lack of clinical efficacy are now demonstrated. Hence, an efficient and safe strategy against uncontrolled BKV replication is urgently needed. MTor-inhibitors are well known immunosuppressive drugs used in organ transplantation to prevent graft-rejection. They have furthermore anti-viral effects that can be beneficial for prevention of viral infections after transplantation. Recent evidence that inhibition of mTor pathway had an impact on BK infected cells provides additional insight into the observed benefits associated with these drugs. The aim of our study is to evaluate the effect of the mTor inhibitor everolimus on the prevention of severe BKV infection (BKV nephropathy or loss of the allograft) after kidney transplantation compared to the reduction of immunosuppression alone in kidney recipients with BK viremia.
Prospective, open-label, single arm, non-randomized, proof-of-concept study. Eligible patients will sign a written informed consent and will be followed-up at screening, baseline (ART interruption) and at 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 32, 40, 48 weeks thereafter or at ART resumption. The study visits will include: general clinical assessment, routine laboratory tests including: creatinine, phosphorus, calcium, alkaline phosphatase, AST, ALT, fasting glucose, total cholesterol, HDL- and LDL-cholesterol, triglycerides, CD4+ cell count and CD4+/CD8+ ratio. Additional 30 mL of peripheral blood will be withdrawn at study visits for further virological, and immunological investigations and for bio-banking purposes. During follow-up, the occurrence of two consecutive HIV-1 RNA values >50 copies/mL or the occurrence of stage B or C AIDS-defining events or any serious non-AIDS clinical event at least potentially related to treatment interruption will be criteria for ART resumption. All patients with HIV-RNA<50 copies/mL at week 48 (end of the study) will resume their baseline ART regimen. The main demographic, clinical and therapy information will be accurately recorded at the study visits in an electronic Case Report Form.
This trial addresses the question of the viral load (VL) threshold for switching from first-line to second-line antiretroviral therapy (ART). The WHO currently sets the threshold at 1000 copies/mL. However, the optimal threshold for defining virological failure and the need to switch ART regimen has not been determined. In fact, people with VL levels of less than 1000 copies/mL, however, not fully suppressed, are at increased risk for drug resistance mutations (DRM) and subsequent virological failure. In resource-limited settings where VL monitoring is not as frequent as in high-income countries, this could have serious implications and patients may continue on a failing regimen for a long period. Our research consortium will conduct a multicenter, parallel-group, open-label, randomized clinical trial in a resource-limited setting to assess whether a threshold of 100 copies/mL compared to the WHO-defined threshold of 1000 copies/mL for switching to second-line ART among unsuppressed HIV-positive patients on first-line ART will lead to better outcomes.
This is a two-center study of 30 HIV-infected participants who have been on antiretroviral therapy (ART) for at least two years. Participants will be asked to undergo LN and GALT biopsies both before and after a closely monitored analytic treatment interruption (ATI).
This is an expanded access protocol designed to provide access of ATA230 to subjects with cytomegalovirus (CMV) viremia or disease, who are intolerant to, or failed, standard antiviral therapy and have no comparable treatment options.
The primary objective of this protocol is to provide expanded access to tabelecleucel to participants with Epstein-Barr virus-associated diseases and malignancies for whom there are no other appropriate therapeutic options, and who are not eligible to enroll in clinical studies designed to support the development and registration of tabelecleucel.
The study will prospectively determine the clinical utility of CMV cell-mediated immunity using the Quantiferon test. The investigators will use the assay results to tailor the duration of CMV prophylaxis in solid organ transplant patients.
The overall goal of this study is to rapidly improve clearance of BK viremia with Immunoglobulin (Privigen®) thereby decreasing the potential for formation of alloantibodies in renal transplant recipients that have had immunosuppression reduction due to BK viremia. Our approach is to perform a prospective, randomized, placebo controlled trial intravenous immune globulin (IVIg; Privigen®) plus protocolized immunosuppression reduction versus placebo and protocolized immunosuppression reduction in patients with BK viremia post-kidney transplantation.
Background: When there is a threat to the body, the immune system triggers inflammation. Too much inflammation can damage the body or cause painful symptoms. Some people with HIV feel sick after they start HIV drugs because their recovering immune systems cause too much inflammation. Or their immune systems can become activated all the time. This can cause serious health problems. Researchers want to test if the drug CC-11050 helps treat inflammation in people taking HIV drugs. Objectives: To test if CC-11050 is safe and well-tolerated for people with HIV who are taking HIV drugs. To see if it reduces inflammation. Eligibility: People ages 18 and older with HIV who have been on antiretroviral therapy for at least 1 year. Design: Participants will be screened with: Medicine review Physical exam and medical history Blood and urine tests Chest x-ray Electrocardiogram (ECG): Soft electrodes on the skin record heart signals. Participants will be randomly assigned to take capsules of either CC-11050 or a placebo. They will take the capsules every day for 12 weeks. They will continue to take their HIV drugs. Participants will have a baseline visit within 2 months of screening. This includes: Physical exam and medical history Blood and urine tests ECG Leukapheresis: Blood is removed by a needle in one arm and passed through a machine that removes white blood cells. The rest of the blood is returned through a needle in the other arm. Participants will have follow-up visits 2, 4, 8, 12, and 16 weeks after the baseline visit. These may include repeats of some of the baseline tests.
