Filter by:Pain in Herpes is a serious issue for patients. at the acute phase it is a moderate to severe pain . 30% patients will develop a post herpetic neuralgia this percentage up to 70 % after 60 years old. this post herpetic neuralgia will affect their life. Publication showed the efficiency of regional anesthesia on pain at the acute phase and a recent meta-analysis showed the role of efficient pain relief on the prevention of post herpetic neuralgia. there are still 2 questions to answer: 1/ do we need to perform the regional anesthesia to relief the pain at an early stage of after no response to the medical treatment? 2/ Are repeated blocks more efficient than a single block?
Varicella zoster virus (VZV) can lead to significant morbidity and mortality in transplant recipients. Current recommendations suggest a 4 week waiting period between vaccination and transplantation and consideration of booster immunizations if antibody response does not reach target levels. This four week waiting period can result in delayed transplant, rejection of an optimal organ, or missed opportunity to vaccinate. However, these recommendations are not evidence based. This is a prospective study to look at the immune response to varicella vaccine in children with chronic liver disease. Investigators will evaluate: 1. the time at which VZV DNA becomes undetectable in blood and saliva by PCR after vaccination in children with chronic liver disease and 2. the difference in humoral and cell mediated immune response to varicella immunization between children with chronic liver disease and healthy children.
The purpose of this study is to investigate whether there is an association between stroke or heart attack and reactivation of varicella zoster virus, measured by antibody levels, using linked data from the Health Survey for England and secondary care.
The study will evaluate the consistency of 3 lots of inactivated VZV vaccine for safety, tolerability, and immunogenicity in healthy adults. The primary hypothesis of the study is that the 3 lots of inactivated vaccine will demonstrate similar immunogenicity at 28 days after the fourth dose.
The purpose of the study is to learn more abou how the immune system responds to the chickenpox vaccine in adults who had never had chickenpox as a child and were then vaccinated as an adult. The study aims to learn more about the strength and duration of the protection provided by the vaccine in adults, and to observe the immune response to an additional dose of chickenpox vaccine in adults who had received the vaccine at least 5 years earlier. This is especially relevant to workers in a hospital who may be exposed to chickenpox.
This study will collect data on the safety of the MMRV vaccine (Priorix-Tetra™) used in routine practice in children aged 12 months to 12 years living in the Philippines.
This study will test the immunogenicity, safety, and tolerability of VARIVAX™ manufactured with the Varicella Enhanced Process (VEP) compared with the VARIVAX™ 2007 Process. The primary hypotheses being tested are 1)VARIVAX™ VEP will induce varicella-zoster virus (VZV) antibody responses that are non-inferior to those induced by VARIVAX™ 2007 process at 6 weeks after vaccination 1, and 2) VARIVAX™ VEP will induce an acceptable anti-VZV antibody response rate at 6 weeks after vaccination 1.
The goal is to demonstrate the immunogenicity and safety of Zostavax® in HIV positive individuals. Study participants are stratified into different patient groups according to their CD4 cell count, viral load and HIV Status. - Trial with medicinal product - Trial with immunomodulatory product / biological
