Filter by:The National Vaccination Program, updated by the Ministry of Health in 2021, provides a new vaccination opportunity for frail patients against Herpes zoster virus (HZ). The new treatment option, on the other hand, is designed by combining VZV-specific antigen (gE) with an adjuvant system (AS01B) to induce antigen-specific cellular and humoral immune responses in individuals with preexisting immunity to VZV. Efficacy, assessed in people given two doses 2 months apart, is around 97% in those aged 50 years and 91% in those over 70 years. In the studies conducted, HZ-related hospitalizations were significantly reduced. The vaccine schedule calls for the administration of two doses 2 months apart. The current HZ Vaccination Program implemented at the regional level recommends its active and free offer in people from 18 years of age with congenital and/or acquired immunodepression, through a collaborative relationship involving, on the one hand, multispecialist and multiprofessional medical staff and, on the other hand, citizens called to play a role that is no longer passive but the subject of empowerment by consciously making their own health choices. The collaboration with ASL Roma1, in this sense, acquires value as guarantor of the supply of the adjuvanted recombinant anti-HZ vaccine and of the appropriate reporting of vaccination coverage, which to date is still far from the targets set by the PNPV'17-'19 in adults at risk for disease. The purpose of this study Single-center prospective longitudinal observational cohort study is to verify patients' compliance with the proposed vaccination, the effectiveness of counseling carried out by a multidisciplinary team in the hospital setting.
The purpose of this pilot study is to determine if the use of Purell hand sanitizer alters the duration, level of pain and discomfort during treatment, and the size of the HSV-1 lesion. The duration of an HSV-1 (herpes) lesion is the primary endpoint for this study. Size, pain, and discomfort are the secondary endpoints.
Almost 90 out of 100 people carry herpes simplex viruses (HSV). Once a person has been infected with the herpes viruses, he or she can't get rid of them for the rest of her/his life. For the most part, the viruses are in a dormant state. Only when the immune system is weakened, for example in the case of a serious illness or stress, are the viruses reactivated. They then mainly cause cold sores, which are harmless for healthy people and usually heal without therapy. However, especially in people with a weakened immune system, HSV can also cause serious infections, such as meningitis. In almost every second mechanically ventilated patient in intensive care who has pneumonia, HSV can be detected in the respiratory tract. This is caused by reactivation of the viruses as a result of the severe underlying disease and stress during intensive care therapy. Whether treatment of the herpes viruses (e.g. with acyclovir) is necessary in this situation and helps the patients to cure has not been clarified, especially as acyclovir can also cause side effects such as a deterioration in kidney function. Currently, the physicians decide to treat the herpes viruses in about half of the patients. Several studies have shown that patients for whom the physician decided to treat the viruses survived more often. However, all of these studies looked at the course of the disease only retrospectively and thus are subject to many biases (including physician selection of who receives treatment, missing data). A definitive conclusion as to whether herpesvirus therapy can be recommended cannot be drawn without doubt from these studies. Therefore, the investigators would like to investigate in a randomized controlled trial, i.e. patients are randomly assigned to the experimental (therapy of herpesviruses) or control group (no therapy of herpesviruses), the effect of therapy with acyclovir on survival in mechanically ventilated intensive care patients with lower respiratory tract infection (pneumonia) in whom a large amount of HSV was found in the respiratory tract. The goal of the study is to provide clarity on whether therapy will help patients recover.
This clinical trial is to study protective efficacy and safety of a recombinant herpes zoster vaccine (LZ901) and sponsored by Beijing Luzhu Biotechnology Co., Ltd. It is a phase Ⅲ, randomized, double-blind, placebo-controlled in healthy people aged 40 years and older. The study is to protect adults against shingles (herpes zoster / varicella zoster virus(VZV)). There will be about 26000 participators who will receive two-dose injection at the upper arm. LZ901 vaccine is made up of a tetramer of VZV glycoprotein E (VZV gE-Fc) and adsorbed with aluminum hydroxide adjuvant. This adjuvant can raise the immune response to a lot of antigens. It is the most widely used and safe adjuvant in various types of vaccines worldwide.
In Italy, the 2017-2019 National Immunization Plan recommended specific vaccinations for the elderly, defined as those 65 years old and older, and at-risk adults with age 50+ (adults presenting cardiovascular, respiratory, or metabolic diseases, immunodepression, etc.). However, the coverage target set by the Plan (50% for Herpes Zoster vaccination in 2019) was not reached. Providing additional data on the incidence of Herpes Zoster could improve the risks perception of the disease and the vaccination uptake. The present study will aim to describe a full picture of Herpes Zoster associated hospital admissions in Italy, focusing on co-morbidities which induce reduced varicella-zoster virus-specific cell-mediated immunity response. Furthermore, as varicella-zoster virus reactivation was reported in COVID-19-positive patients, a deepening on a possible relationship between the two infections will be investigated.
This study is an observational, cohort, prospective study looking at the frequency of Herpes Simplex Virus (HSV) 1 and or 2 outbreaks in HIV positive patients who's HIV virus is controlled on highly active anti-retroviral therapy. We will be enrolling fifty (50) patients.
This clinical trial is to study the safety and tolerability of a recombinant herpes zoster vaccine (LZ901) and sponsored by Beijing Luzhu Biotechnology Co., Ltd. It is a phase I, randomized, double-blind, placebo-controlled, dose escalation study in healthy people aged 50 to 70 years inclusive. The study is to protect adults against shingles (herpes zoster / varicella zoster virus(VZV)). There will be about 66 participators who will receive two-dose injection at the upper arm. LZ901 vaccine is made up of a tetramer of VZV glycoprotein E (VZV gE-Fc) and adsorbed with aluminum hydroxide adjuvant. This adjuvant can raise the immune response to a lot of antigens. It is the most widely used and safe adjuvant in various types of vaccines worldwide. In this study: 1. The participation is voluntary. 2. Before the study, participants will receive some tests for screening. If qualified, investigators will officially invite them to join this study. 3. The study vaccine is LZ901 with two different dose levels (50μg/0.5 mL, 100μg/0.5 mL). The placebo, which is saline solution, has no active drug. Participants will receive one of three as above mentioned. 4. Participants will be enrolled in one of four cohorts. If participants are enrolled in Cohorts 1 or 2, they will receive LZ901. If participants are enrolled in Cohorts 3 or 4, they will have a 2 out of 3 chance (66%) of receiving LZ901 and 1 out of 3 chance (33%) of receiving placebo. 5. In Cohort 3 and 4, the study staff and participants will not know which study treatment participants will be receiving. However, the study doctor can get this information in case of an emergency. 6. Participants will stay at the clinic for 30 minutes after each vaccination to observe if there are any uncomfortable. 7. This study will last about 8 months and will include about 8 study visits to the clinic. During this period, participants will receive a follow-up phone call and/or email by the study staff to follow the condition closely for safety, and record on diary/contact card. 8. Participants will receive some tests during the study, include safety tests such as physical examination, vital signs measurements, blood tests, urinalysis. Participants will be measured the levels of specific antibodies to see if the vaccine works well. This study is for research purposes only. Participants may not receive any direct benefits from participating in this study but have a chance to be in a study that may help others in the future.
Despite sex education in schools and prevention campaigns concerning sexually transmitted infections, genital herpes remains frequent infection. In 2016, according to the World Health Organization, more than 490 million people worldwide were living with a genital herpes infection.
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.
A Phase 1 study that will determine the valacyclovir dose that results in a systemic acyclovir exposure comparable to 10 mg/kg of parenterally administered acyclovir, which is an AUC0-12 of 24,000 ngxhr/mL to 48,000 ngxhr/mL. Neonates at risk of acquiring neonatal HSV will be enrolled in one of 2 cohorts. Cohort 1 will be comprised of eight subjects who will receive an initial dose of 10ml/kg of oral valacyclovir. Samples for PK assessments will be obtained to assess the exposure concentration. If the safety profile and the drug exposure concentrations in Cohort 1 are acceptable, eight new subjects will be enrolled in Cohort 2. The dose that these subjects will receive will be predicated upon the pharmacokinetic data from Cohort 1.
