Filter by:Vaccines are used to prevent infectious diseases worldwide. Unfortunately, many vaccines, like the flu vaccine, are less effective in older adults. This single-centre open label partially randomised, partially placebo-controlled trial evaluates the differences in immune response between young and older adults after vaccination with a quadrivalent inactivated influenza vaccine and an adjuvanted herpes zoster vaccination. Exploring the underlying mechanisms between the differences in immunogenicity can provide important information for future vaccine development.
A five-month-old healthy girl who presented with painful herpetic gingivostomatitis and perioral vesicles.
This study examined the efficacy, safety and benefits of modern treatment and changes in the dynamics of the life of adult patients quality with severe herpes simplex in the current medical practice when combined therapy by acyclic nucleoside Valacyclovir and antiviral agent Kagocel versus monotherapy by Valacyclovir. This study also evaluated the structure of herpesvirus infections and the rate of mixed variants of the course, the rate of exacerbations of herpes simplex, the time of disappearance of human herpesvirus isolation and the features of the immune phenotype of patients taking different types of therapy.
The purpose of this study is to evaluate the safety, tolerability and efficacy of a single escalating doses of BD111 CRISPR/Cas9 mRNA Instantaneous Gene Editing Therapy administered via corneal injection in participants with refractory herpetic viral keratitis.
This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.
Lesions of herpes labialis are caused by the herpes simplex virus type 1 (HSV-1) and cause pain and aesthetic compromise. It is characterized by the formation of small vesicles that coalesce and rupture forming extremely painful ulcers, that evolve to crusts, dry desquamations until their complete remission. Currently, the treatment of these lesions is done with acyclovir. Although it diminishes the symptomatology, it causes viral resistance and does not prevent the recurrence of the lesions. It is known that photodynamic therapy (PDT) has numerous advantages, among them: the reduction of the time of remission, and does not cause resistance. A total of 30 patients with herpes labialis in the prodromal stage of vesicles, ulcers, and crusts will be selected to participate in the study and randomized into two groups: G1 control and G2 experimental. After signing informed consent, patients in group G1 will undergo the standard gold treatment for cold sores with acyclovir and simulated PDT treatment. Patients in the experimental G2 group will be treated simulating the gold standard treatment of herpes labialis (placebo) and PDT.
Subjects were recruited who were positive for antibody against herpes simplex virus type 1 (HSV-1) and self-reported having in the previous 12 months - 6 or more herpes labialis outbreaks (group A), - 1 or 2 outbreaks (group B), or - zero outbreaks (group C). Twelve subjects in each group were recruited. Blood was collected from these persons and peripheral blood mononuclear cells (PBMCs) isolated and tested for proliferation in vitro when stimulated with HSV-1-infected cell extracts, free HSV-1 virus, or Candida albicans extract. Candida albicans is a ubiquitous infectious fungus and its extract is used as a test of general immune response. RNA was also isolated from the PBMCs after incubation in the three stimuli and expression of 41 immune-related genes quantified by quantitative real-time PCR. Also serum anti-HSV-1 IgG levels were quantified. After the blood collection on day 1, the persons in group A (frequent cold sore sufferers) were treated with a single topical application of 2% squaric acid dibutyl ester (SADBE) in DMSO, applied to the inner aspect of the upper arm. These subjects returned on days 15 and 57 for blood collection, and their PBMCs were tested again on those dates for proliferation in vitro against the same stimuli and for gene expression and for serum anti-HSV-1 IgG levels.
This study aims to evaluate the efficacy of an intervention designed to reduce STI/HIV incidence by increasing the number of adolescent mothers who re-enroll and remain in school. The objective of the intervention is to have older mentor mothers, who themselves were pregnant adolescents, to mentor younger adolescent mothers. Mentor mothers will provide ongoing psychosocial support, help navigate re-admission to school, and help facilitate access to an existing State-sponsored cash transfer, the child support grant (CSG), in the early postpartum period. Our combination social protection program will enhance resilience of young adolescent mothers to facilitate their return to school and thereby reduce HIV risk. The investigators will evaluate the efficacy of the intervention using a pre-test post-test randomized controlled trial design. Participants in the intervention will receive the Mentoring Adolescent Mothers At School (MAMAS) intervention and standard postpartum care. Those in the control arm will receive standard postpartum care. Additionally, for those participants randomized to the intervention arm, mentor mothers will use participatory visual methods (e.g., photovoice, cell-films, drawings) as part of the intervention itself. Last, among those participants randomized to the intervention arm and who return for their 9-month assessment, the investigators will conduct 20 in-depth interviews to understand the process of resilience development from their perspective. Primary outcomes: School outcomes (initial outcomes) HYP 1.1: Program participation will increase school enrollment HYP 1.2: Program participation will increase school engagement HIV risk outcomes (intermediate outcomes) HYP 2.1: Program participation will reduce number of sexual partners HYP 2.2: Program participation will reduce inconsistent condom use HYP 2.3: Program participation will reduce intimate partner violence HYP 2.4: Program participation will decrease HIV/STI infection HYP 2.5 (for HIV+): Program participation will increase retention in care Secondary outcomes: HYP 5: Program participation will increase peer support HYP 6: Program participation will increase familial support HYP 7: Program participation will increase school re-admission HYP 8: Program participation will increase application to the child support grant HYP 9: Program participation will increase receipt of the child support grant
This study investigates the effects of Valaciclovir treatment to individuals with Alzheimer's disease or Mild Cognitive Impairment of Alzheimer's Disease Type. It is an open pilot trial where 36 participants will receive 4 weeks of Valaciclovir treatment. Participants will be investigated using different measures before and after the treatment period.
This study is a follow-up study from Study GEN-003-002 to evaluate long-term efficacy and immunogenicity of GEN-003 in subjects with genital HSV-2 infection.
