Filter by:The purpose of the study is to assess the efficacy, safety and tolerability of NGX 4010 applied for 60 minutes for the treatment of PHN.
The purpose of the study is determine if an investigational drug, NGX-4010 (high-concentration capsaicin dermal patches) is effective in treating pain associated with post-herpetic neuralgia (PHN).
Shingles is an infection commonly seen in children with a weakened immune system (immunocompromised children). The immune system can be weakened as a result of medications that patients receive for cancer or other serious illness or as a result of a bone marrow transplantation. Shingles in children with a weakened immune system may spread throughout the body and in some instances may be life-threatening. Acyclovir is a medication that is routinely used to treat immunocompromised children with shingles in order to prevent further spread of their shingles and to help them heal faster. Acyclovir is also given to bone marrow transplant patients to prevent reactivation of HSV infection. Valacyclovir is a new drug that is metabolized (broken down in the body) to acyclovir. Valacyclovir is given by mouth and studies done in adults have shown it to be more effective than acyclovir given by mouth. The purpose of this study is to - study the pharmacology of this drug (how the body handles this drug), - determine if oral Valacyclovir can be safely given to children with shingles, and - determine the type of side effects that occur when oral Valacyclovir is given to immunocompromised children.
The purpose of this study is to gain initial information on the tolerability of high-dose capsaicin patches in patients with Painful Postherpetic Neuralgia. The study will also collect preliminary information on safety and efficacy.
A randomized control trial testing whether a relaxation response based intervention, Tai Chi Chih, will affect Varicella Zoster Virus (VZV) specific immunity measures of psychological adaptation and health function in the older adult.
The incidence and severity of HZ (or shingles), as well as the frequency and severity of its complications, increases markedly with increasing age. More than half of all cases occur in persons over the age of 60. Even without complications, HZ can interfere with an elderly patient's ability to perform essential activities of daily living, resulting in a loss of independence that is emotionally devastating and frequently irreversible. The most common complication of HZ in elderly persons is postherpetic neuralgia (PHN), which frequently results in disordered sleep, chronic fatigue, anxiety and severe depression. Antiviral therapy has a modest impact on the acute phase of HZ. However, it does not appear to prevent the development of PHN. This study is a 5.5 year randomized, double-blind, placebo-controlled, efficacy trial to determine whether vaccination with live-attenuated Oka/Merck varicella-zoster decreases the incidence and/or severity of herpes zoster (HZ) and its complications in adults 60 years of age and older.
OBJECTIVES: I. Compare the efficacy and safety of two doses of oral valacyclovir in immunocompromised patients with uncomplicated herpes zoster. II. Compare quality of life, pain, and medical resource utilization in patients treated with these 2 regimens.
OBJECTIVES: I. Determine whether opioid (morphine) treatment results in better management of pain than treatment with tricyclic antidepressant (nortriptyline). II. Assess the effects the two treatments have on affective and cognitive functions. III. Determine whether the presence of psychiatric comorbidity, particularly depression, can predict the outcome of the two treatments.
To determine the efficacy of oral 882C87 compared with oral acyclovir in the treatment of localized herpes zoster in immunocompromised patients. To assess the safety and tolerance of oral 882C87 in immunocompromised patients.
In our current clinical trial, we are comparing the effects of two NMDA receptor antagonists to placebo in patients with painful distal symmetrical diabetic neuropathy or post-herpetic neuralgia. The treatments in this three-period crossover study are dextromethorphan, up to 920 mg/day (about 8 times the antitussive dose), memantine, 30-50 mg/day, and placebo. Memantine is an NMDA antagonist used in Europe to treat Parkinson's disease and Alzheimer's disease. The underlying hypothesis, based on studies of painful neuropathies in animal models, is that neuropathic pain is caused largely by sensitization of central nervous system neurons caused by excitatory amino acid neurotransmitters, acting largely through NMDA receptors. A previous small trial of dextromethorphan suggested efficacy in diabetic neuropathy pain. The study requires one visit to the NIH outpatient Pain Research Clinic, and consists of three 9-week treatment periods. Patients who respond to one of the medications will be invited to participate in further controlled studies of the medication followed by up to several years of open-label treatment under continued observation.
