Active clinical trials for "Herpes Simplex"

This is a prospective, randomized clinical trial looking to determine the role of prophylactic treatment with topical corticosteroids in preventing recurrences in patients with a history of infectious epithelial keratitis, stromal keratitis,endotheliitis, or iridocyclitis. Patients will be enrolled to one of two treatment arms: Control arm: oral acyclovir 400 mg BID OR valacyclovir 500 mg daily or Study arm: oral acyclovir 400 mg BID OR valacyclovir 500 mg qdaily + topical corticosteroid eye drops.

Methadone treatment has became one of main actions taken in China to control the spread of HIV among drug users. However，the average methadone dose used is relatively low. An intensive methadone maintenance treatment (MMT) provider training on methadone dosage may be effective in increasing the methadone dose levels prescribed to new patients. The study will evaluate the effectiveness of a tailored education program for MMT service providers using subsequent methadone dose prescribed to new patients. The effects of methadone dose, with and without the inclusion of additional psychosocial services, will then be measured through MMT retention and illicit opioid use.

The purpose of this study is to evaluate the performance of the Sentosa SA HSV1/2 Qualitative PCR Test. Precision of results and concordance of results with a reference assay will be evaluated.

PCR detection of HSV DNA shedding in the female genital tract using the GeneXpert system (Cepheid, Sunnyvale CA) will be compared with traditional (routine) PCR (pregnant and nonpregnant women) and with HSV culture (nonpregnant women). The GeneXpert system performs all sample-processing steps and real-time PCR in a single integrated cartridge. The standard cartridge is an inexpensive disposable plastic cartridge with filtration and ultrasonic lysis capabilities. It consists chiefly of several combined molded plastic components: a cartridge body containing eleven fluid reservoirs or chambers along with an attached PCR tube, a specialized valve body with an ultrasonic interface containing a sub-micron filter and glass lysis beads, and a rotary valve with an axial syringe barrel. The operation of the cartridge is simple. The rotary valve contains an inlet and an outlet port. Fluid such as a sample buffer can be drawn up into a syringe drive through the inlet port of the rotary valve and then dispensed into any other chamber within the cartridge by rotating the valve and expelling the fluid through the outlet port. The fluid can either be passed through a filter contained within the valve assembly or it can be passed directly into the next chamber without filtration, depending on the path that is chosen. The cartridge fluidics and subsequent real-time PCR all are performed within the GeneXpert instrument. The GeneXpert contains multiple modules (ICORE units) that can be independently programmed to drive the syringe/rotary valve, and to perform four-color real-time PCR. Each cartridge fits inside one module, and all processing, PCR, and analysis steps are performed automatically. Each ICORE module can be run and analyzed independently, so batching of samples is unnecessary.

The purpose of this study is to collect data on the incidence, complications, economic burden and impact on the quality of life in adults aged ≥ 50 years with HZ disease in Italy.

The purpose of this study is to determine the seroprevalence of Hepatitis A Virus (HAV), Varicella-Zoster virus (VZV), Cytomegalovirus (CMV), Herpes Simplex (HSV) and Bordetella pertussis (BP)infections in Mexico.

Total 7 institutions will be recruited i.e. Clinical Infectious Disease Research Unit Department of Clinical Tropical Medicine, Faculty of Tropical Medicine Mahidol University,Bamrasnaradura Infectious Disease Institute ,Pramonkutklao Hospital,Rajavithi Hospital,NationalCancerInstitute,Institute of Dermatology,Raj Pracha Samasai Institute OBJECTIVES Measure the burden of illness due to herpes zoster (Zoster) and post-herpetic neuralgia (PHN) (severity and duration); Assess the quality of life (QoL) and quality adjusted life years (QALY) lost due to Zoster and PHN; Describe health care resource utilization associated with Zoster and PHN; Describe the direct and indirect costs per case of Zoster and PHN

This study will examine the structure of the receptor molecule for the herpes simplex virus (HSV) and determine if the receptor's structure is related to susceptibility to infection with the virus. There are two types of herpes virus-HSV-1 and HSV-2. HSV-1 commonly causes cold sores, and HSV-2 usually causes genital herpes. The herpes virus enters (infects) cells through protein molecules on the cell's surface. This study will explore possible differences between the structure of the HSV receptor molecule in different people to understand better how infection occurs. The study will also look at proteins on white blood cells (Fc receptors, cytokines and mannose binding protein) that may influence the risk of infection with HSV. Information from this study may lead to new treatments to prevent HSV infection. People 18 years of age and older who are infected with HSV and people who are not infected with the virus may be eligible for this study. Participants will have blood drawn to confirm whether or not they have been infected with the virus. The blood sample will also be used to study the genes for the HSV receptor, Fc receptors, cytokines, mannose binding protein and related proteins on the white blood cells. No more than 40 milliliters (8 teaspoons) of blood will be drawn. Participants who are found to have antibodies to HSV-2 will be offered counseling and advice on practicing safe sex techniques to help prevent sexually transmitted diseases, including HSV-2 infection.

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.

The purpose of this study is to collect data on the incidence, complications and impact on quality of life of herpes zoster (HZ) disease in adults >=50 years of age in Spain. This study will also collect data on costs related to the HZ disease, especially postherpetic neuralgia (PHN)
