NCT ID: NCT02452229 Completed - Burns Clinical Trials

Review of Human Herpes Viruses in Burns

Start date: March 2015
Phase: N/A
Study type: Observational

Herpes simplex virus, cytomegalovirus and varicella zoster virus infection are purported to play a pivotal role in morbidity and mortality in burns. Thus far, there is no existing systematic review (Level of Evidence III or higher) describing the unique role as well as concurrent infections of these viruses in burns. The aim of this review is to point out the clinical differences between these human herpes virus subtypes, to outline established therapy approaches, and to provide evidence for virus related morbidity and mortality in burns.

NCT ID: NCT01878383 Completed - Clinical trials for Herpes Simplex Virus

Identification of Herpes Simplex Virus (HSV) Shedding in the Female Genital Tract of Pregnant and Nonpregnant Women by GeneXpert PCR, Routine PCR, and Culture

Start date: January 2014
Phase:
Study type: Observational

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.

NCT ID: NCT01431326 Completed - Hypertension Clinical Trials

Pharmacokinetics of Understudied Drugs Administered to Children Per Standard of Care

PTN_POPS
Start date: November 2011
Phase:
Study type: Observational

Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).

NCT ID: NCT00942084 Completed - Neonatal Sepsis Clinical Trials

A Study to Describe the Pharmacokinetics of Acyclovir in Premature Infants (PTN_Acyclo)

Start date: September 2011
Phase: Phase 1
Study type: Interventional

Acyclovir is a drug used to treat herpes simplex virus (HSV) infections in babies. Appropriate dosing of acyclovir is known for adults and children but acyclovir has not been adequately studied in full-term or premature neonates. HSV is a very serious infection in babies <6 months of age and often results in death or profound mental retardation. HSV leads to profound mental retardation in young infants because the virus attacks the central nervous system. The investigators hypothesize that the currently recommended dose of acyclovir is inadequate to produce adequate blood levels to combat herpes simplex infection. The investigators propose to study acyclovir levels in the blood of babies who are placed on acyclovir to treat a suspected HSV infection. This will allow them to determine the appropriate dose in premature infants. This is an unmet public health need because it is likely that the drug behaves differently in premature infants than it does in term infants and older children. Premature babies have more body water and less body tissue. Their kidneys are more immature and do not function as well as full term infants. Premature neonates are also at the greatest risk from herpes infection because they have poorly functioning immature immune systems. Early and appropriate treatment with acyclovir has resulted in improved outcome in term infants.
