Filter by:Randomized prospective multi-center imaging study which investigates the impact of different immunosuppressive protocols (Everolimus (Certican®) or Mycophenolate mofetil (CellCept®)) on cardiac allograft vasculopathy (CAV) in heart transplanted patients. Maximal intima-thickness will be visualized by optical coherence tomography (OCT) to assess the progression of CAV.
The Cologne Cohort of Neutropenic Patients (CoCoNut) is a non-interventional cohort study assessing risk factors, interventions, and outcome of immunosuppressed patients with or without opportunistic infections.
Background: - Gum disease is a condition in which the tissue around the tooth root becomes swollen and infected. This condition can cause tooth loss if it is not treated. Who gets gum disease and how bad it will be depends on (1) the different bacteria in the mouth and (2) how the immune system of an individual handles these bacteria. Researchers want to look at the oral bacteria and genetic immune problems of different people to learn how these affect gum disease and other conditions of the mouth. Objectives: - To study how immune system problems may lead to problems in the mouth, including gum disease. Eligibility: - Children and adults at least 7 years of age who have genetic problems with their immune system. - Healthy adults that have periodontal disease - Health adults that do not have periodontal disease Design: - This study will involve a screening visit and a study visit. - Participants will be screened with a medical history, blood work and a full oral and dental exam, including dental x-rays and photos. - The study visit will involve collection of blood, urine, and other samples, including saliva, plaque, and gum swabs. Any abnormal tissue will sampled for a biopsy. Additional oral and dental exams will be performed. Participants will also answer questions about any current medical or dental problems.
The purpose of this study is to evaluate the immunogenicity and safety of an adjuvanted A(H1N1)v influenza vaccine in HIV-infected and immunosuppressed patients after one and two injections.
This prospective, randomized study, comparing sirolimus to cyclosporine in renal transplant recipients, has two major objectives: 1. -To determine the incidence and the degree of interstitialfibrosis and arteriosclerosis, as wel as the glomerular volume in protocol biopsies at 6 months in sirolimus-and in cyclosporine-treated renal allograft recipients, by means of quantitative computerized image analysis. - To determine the prognostic implication of these morphologic changes. 2. To study the expression of genes, involved in inflammation and fibrosis, in protocol biopsies at 6 months in sirolimus-and cyclosporine-treated renal allograft recipients.
Varicella is a vaccine-preventable disease, which can be severe in immunosuppressed children. Currently, the (live) vaccine is not recommended in pediatric orthotopic liver transplant recipients. Furthermore, protection due to naturally acquired immunity to VZV or post-immunization isn't well described in this population.The questions asked are: - What is the influence of the immunosuppression required after orthotopic liver transplantation (OLT) on the maintenance of VZV-specific immunity elicited by wild-type varicella infection before OLT transplantation? - What is the influence of the immunosuppression required after OLT on VZV-specific immunity elicited by varicella immunization before OLT transplantation? - What is the influence of the residual immunosuppression at ≥ 12 months after OLT transplantation on the induction of VZV-specific B and T cell responses elicited by VZV vaccination after OLT transplantation? - What is the influence of the residual immunosuppression at ≥ 12 months after OLT transplantation on the persistence / waning of B and T cell responses elicited by VZV vaccination?
