Hematopoietic stem cell transplantation (HSCT) is well-established therapy for patients with malignant hematological diseases. Varicella zoster virus (VZV) reactivation, clinically manifested as herpes zoster (HZ), is a major complication that affects up to 50% of patients. Most patients will require hospitalization. Despite treatment with high dose acyclovir, patients may develop severe complications including the disabling postherpetic neuralgia, corneal ulceration, viral dissemination and secondary bacterial infection. The median onset of infection is the fifth month following transplantation, with 91% of cases occurring within the first year. Direct vaccination of transplants recipients with subcutaneous live-attenuated VZVv before transplantation and up to one year after transplantation is contraindicated. A small prospective non-randomized study has demonstrated that subcutaneous vaccination for donors before HSCT may offer some protection against VZV reactivation in the recipients. Recently, dose-sparing influenza vaccine delivered via a novel intradermal microneedle has been shown to elicit a good immunogenic response in both healthy and elderly subjects. We sought to assess the efficacy and safety of the novel intradermal live-attenuated VZVv in sibling donors undergoing HSCT.
A new paediatric formulation (oral liquid) has been developed for flexible and accurate dosing of valacyclovir in children. To establish the bioavailability of this new formulation, healthy volunteers will be exposed to the new formulation and to valacyclovir tablets. The concentration of valacyclovir in their blood after exposure to the oral liquid will be measured and compared to the tablet.
Palatability testing of a new paediatric formulation of valacyclovir in children 4-12 years of age and at least one of their parents. Children will be included, who received (val)acyclovir prophylaxis in the past, or will probably need it in the future i.e. children with primary immune deficiency or cancer.
Herpes Zoster (shingles) is caused by reactivation of latent varicella zoster virus (VZV) that usually occurs decades following initial exposure. The risk of developing shingles increases with age. Shingles presents as a painful, itchy blistering rash that usually involves a single portion of the skin and lasts about 7-10 days. The risk of developing shingles increases with age in healthy people, and has been shown in some studies to be increased in people with rheumatoid arthritis and other autoimmune diseases. Zostavax, a live-attenuated vaccine against the varicella zoster virus, was first approved by the FDA for the prevention of Shingles among people 60 years and older, and is now approved for use in people aged 50 years and older. Because rheumatoid arthritis and some of the medications used to treat rheumatoid arthritis can impair the body's immune system, it is not known how much of an immune response can be generated in people with rheumatoid arthritis. The goals of this study are to measure the immune response after standard vaccination with Zostavax in people with rheumatoid arthritis in comparison to people with healthy immune systems. All participants will be 50 years old or older, and subjects with rheumatoid arthritis will not be eligible if they are taking certain biologic medications, including TNF inhibitors (Etanercept or Adalimumab). Ten healthy subjects and 10 subjects with rheumatoid arthritis will all receive a single vaccination with Zostavax, then will be followed for 12 weeks to assess the immune response and for the development of local rash or other potential side effects.
To study about the immunogenicity, safety and efficacy of varicella-zoster virus vaccine in HIV-infected children.
