Filter by:Kidney transplant recipients are at increased risk of infections, including Varicella-zoster virus (VZV) infections. Vaccination against VZV is routinely offered to all kidney transplant recipients and candidates in Denmark. In this exploratory observational study, the VZV specific immune response in kidney transplant candidates and recipients will be characterized at different time points in relation to transplantation, vaccination and infections. More knowledge on the immune reaction to transplantation, VZV vaccination and VZV infections may provide improved strategies for prevention and treatment of VZV infections in kidney transplant candidates and recipients.
The purpose of this study is to provide evidence as to whether RZV is immunogenic with an acceptable safety profile in Multiple Sclerosis patients on anti-CD20 treatment.
Background: Shingles is a painful, blistering rash caused by the same virus that causes chickenpox. Shingrix is a vaccine approved to prevent shingles in healthy adults over age 50 and in immunocompromised adults over age 18. Researchers want to learn more about how people with HIV respond to Shingrix. Objective: To learn how Shingrix affects the immune response in people with HIV. Eligibility: People aged 18 years and older with HIV. Healthy people aged 50 years or older are also needed. Design: Participants will have at least 4 clinic visits in 1 year. Participants will be screened. They will have a physical exam with blood and urine tests. At their first visit, participants will receive Shingrix as a shot in the upper arm. They will have a rectal swab; a cotton swab will be inserted into the rectum and rotated gently to collect bacteria. Participants will receive a second shot of Shingrix 2 months after the first one. They will visit the clinic again 3 and 12 months after the first shot. Participants will receive a 28-day memory tool. They will write down their symptoms between clinic visits. They will have up to 4 phone calls to talk about side effects of the shot. Participants may undergo apheresis: They will lie still while blood is drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in their other arm.
To compare the efficacy and tolerability of three different doses of Pascorbin® besides standard medication with placebo and the reduction of herpes zoster-associated clinical symptoms as an add-on therapy for patients suffering from acute herpes zoster in primary care
This randomized, double-blind, placebo-controlled, non-inferiority crossover study will evaluate the Herpes Zoster Sunbit (HZ/su) vaccine in SLE patients in order to evaluate safety and immunogenicity in patients with variable baseline clinical activities, ages and immunosuppressant exposures. The investigators hypothesize that HZ/su administration will be non-inferior to placebo with respect to the risk of moderate or severe SLE flare(s) occurring within 24 weeks of receiving the first dose of the assigned treatment. In addition, the investigators hypothesize that immunogenicity of the vaccine in SLE patients will be at least 50% of levels observed in healthy subjects from prior large clinical trials.
This is a phase II study that will examine the immunogenicity of the Shingrix vaccine in patients following an allogeneic stem cell transplant.
Herpes zoster is a common disease, usually caused by the reactivation of latent varicella zoster virus from the dorsal root ganglion. Acute herpes zoster is characterized by severe pain and the appearance of vesicular skin rashes that usually heal in 2-3 weeks. One of the complications of acute herpes zoster is post-herpetic neuralgia (PHN), which is usually defined as persistent pain lasing 90 days or more from the onset of skin rash. The reported incidence of PHN ranges from between 5% to over 50%. PHN can negatively impact one's quality of life due to serious physical, psychological, functional, and social disturbances due to consequences of chronic pain. Platelet rich plasma (PRP) is an emerging treatment option for chronic pain. It is currently used predominantly for treating musculoskeletal pain conditions such as osteoarthritis and tendinopathies. However, PRP promotes the healing of nerve injury and reduces neuropathic pain, making it a potentially promising treatment option for neuropathic pain. The effect of interlaminar epidural PRP for PHN has not been studied. In this study, a case series will be performed to investigate the analgesic effect of interlaminar epidural PRP for patients with thoracic herpes zoster.
Liver transplantation is the only curative treatment of end-stage liver disease, and every year, around 60 patients undergo liver transplantation in Denmark. Immunosuppressive therapy is necessary to avoid rejection of the transplanted organ. Over 90% of adults have been infected with at least one herpesvirus, and it is characteristic for herpesviruses that after a first-time infection, the virus remains dormant in the body and may reactivate, particularly if the host is immunosuppressed. An effective immune response against reactivation depends highly on T cells, but T cells are suppressed by immunosuppressive drugs given to organ transplant recipients. Infections caused by herpesviruses are therefore very common in organ transplant recipients, and particularly two herpesviruses, cytomegalovirus (CMV) and varicella-zoster virus (VZV) pose challenges after transplantation. CMV causes significant morbidity in transplant recipients, contributes to increased mortality and may contribute to loss of the transplanted organ. CMV infections occur in around 40% of liver transplant recipients within a year of transplantation. VZV causes chickenpox at first-time infection and shingles at reactivation. VZV is the second-most common infection in transplant recipients and occurs in around 9% of liver transplant recipients each year. Organ transplant recipients are at higher risk for disseminated disease with complications compared to immunocompetent persons. A limited number of drugs exist that reduce the risk of and treat CMV infection, but they may cause significant adverse events, and drug resistance is emerging. To avoid CMV infection, some liver transplant recipients receive prophylactic therapy, but due to toxicity, new treatment modalities are warranted. This requires knowledge about herpesvirus specific T cell function in liver transplant recipients, which currently is limited. The aim of this study is to provide an in-depth description of the protective immune response and immunological risk factors for CMV and VZV infections in liver transplant recipients and to identify patients at high risk in order to provide a platform for future treatment modalities against CMV and VZV infections in liver transplant recipients.
This study is a randomized and controlled Phase IV clinical trial.The purpose of this study is to evaluate the immunogenicity and safety of combined immunization with live attenuated varicella vaccine and inactivated hepatitis A vaccine in children aged 12-15 months.
