Immune response to the recombinant vaccine against shingles in HIV-positive patients over 50 years old compared to an age- and sex-matched control population - a multicenter phase IV study_ Shingr’HIV
Résumé de l'étude
Shingles is caused by the reactivation of the chickenpox virus that remains in the nervous system for life once chickenpox is cured. Shingles presents as pain and a rash and can be complicated by severe and persistent pain (postherpetic neuralgia). The occurrence of shingles and postherpetic neuralgia increases beyond 50 years and in immunocompromised patients, particularly in people living with HIV. • There is a vaccine against shingles, Shingrix®, approved in Switzerland for all individuals over 50 years old as well as for all adults over 18 years old who are severely immunocompromised. • Although studies have shown that Shingrix® is well tolerated and effective in young HIV patients, the vaccine response in older patients who have lived with HIV for a long time is still not well understood, which may make their immune system less effective. Nevertheless, these patients are vulnerable to shingles and are part of the priority groups for vaccination. • The aim of this study is therefore to characterize the immune response and potential side effects of the Shingrix® vaccine in older HIV-positive patients treated with antiretroviral medications. Their response will be compared to that of a control group consisting of individuals over 50 years old and representative of the general population.

Intervention étudiée
Recombinant vaccine against shingles (Shingrix) administered intramuscularly in two doses separated by an interval of two months.
(BASEC)
Maladie en cours d'investigation
HIV-positive patients are considered at risk of developing a severe form of shingles due to a weakened immune system.
(BASEC)
HIV patients - participants registered in the Swiss HIV Cohort (SHCS) - over 50 years old - on antiretroviral therapy for more than 10 years - not having received the shingles vaccine - HIV viral load < 50 copies/ml Controls: - over 50 years old - not having received the shingles vaccine (BASEC)
Critères d'exclusion
- Ongoing signs of febrile or non-febrile infection at the time of the first vaccination. - Immunosuppression due to the following factors: o current malignant neoplasm o primary immunodeficiency; o recent transplantation (<2 years) of solid organs or bone marrow or any transplantation still requiring immunosuppressive treatment o Use of immunosuppressive medications (e.g., long-term glucocorticoids [an equivalent dose of prednisolone > 20 mg/day > 3 months], monoclonal antibodies, cytostatics, biological products, etc.) in the last 2 weeks - Having received a vaccine in the last month or scheduled to receive a vaccine in the next month - Having received a shingles vaccine in the past year - Having had shingles in the past year - Contraindication to RZV - Hospitalized patients - Unable to provide informed consent or to follow the study procedures, for example due to language issues, psychological disorders, dementia, etc. of the participant. - Participation in another study with an experimental drug within 30 days prior to and during this study.
