Filter by:To evaluate the safety and efficacy of intermittent intravenous (IV) foscarnet in the treatment of acyclovir-resistant herpes simplex virus (HSV) infections in AIDS patients and other immunocompromised patients. To evaluate the necessity, efficacy, and safety of IV maintenance foscarnet therapy in preventing recurrent disease. To confirm the pharmacokinetics of intermittent induction and maintenance IV regimens.
To evaluate the safety of topically applied SP-303 gel and to compare the efficacy of SP-303 gel in combination with acyclovir, relative to acyclovir alone, for the treatment of recurrent Herpes Simplex Virus (HSV) 1 and 2 infections, affecting the genital, perianal and neighboring areas, in patients with AIDS.
The purpose of this study is to see if cidofovir gel (Forvade) is safe and effective in treating herpes simplex in patients with AIDS who do not respond to acyclovir.
PRIMARY: To evaluate the clinical activity of foscarnet cream on the index lesion of mucocutaneous herpes simplex virus (HSV) infections in immunocompromised patients previously unresponsive to acyclovir treatment. SECONDARY: To evaluate the clinical activity and virologic activity of foscarnet cream on all treated lesions in this patient population. To evaluate the local tolerance and side effects of treatment with foscarnet cream in this patient population.
To evaluate the safety and tolerance of topical cidofovir (HPMPC) therapy for refractory mucocutaneous herpes simplex virus disease in AIDS patients. To determine whether topical HPMPC therapy can induce re-epithelialization and healing of refractory mucocutaneous herpes simplex virus disease in AIDS patients. To evaluate the virologic effects of topical HPMPC therapy on herpes simplex virus shedding from refractory lesions.
To determine the safety and efficacy of oral valacyclovir hydrochloride ( 256U87 ) compared to acyclovir in the treatment of recurrent anogenital herpes in HIV-infected patients with CD4 counts = or > 100 cells/mm3.
To evaluate the safety and efficacy of intermittent intravenous (IV) foscarnet in the treatment of acyclovir-resistant herpes simplex virus (HSV) infections in AIDS patients and other immunocompromised patients. To evaluate the necessity, efficacy, and safety of IV maintenance foscarnet therapy in preventing recurrent disease. To confirm the pharmacokinetics of intermittent induction and maintenance IV regimens.
To evaluate the safety and efficacy of oral valacyclovir hydrochloride (256U87) vs. acyclovir in the treatment of recurrent anogenital herpes in HIV-infected patients (CD4 greater than or equal to 100).
This study will evaluate the effectiveness of the drug valaciclovir in preventing transmission of genital herpes from an infected to an uninfected sexual partner. Genital herpes is caused by the herpes simplex virus 2 (HSV-2), or, infrequently herpes simplex virus 1 (HSV-1). Valaciclovir prevents the herpes virus from multiplying and may also reduce its transmission between partners. Couples 18 years of age and older in which one partner is infected with HSV-2 (source partner) and the other is not (susceptible partner), may be eligible for this study. Candidates will be screened with blood tests for routine laboratory studies and to verify the presence or absence of HSV-2 or HSV-1 infection. Participants will give a medical history, undergo a physical examination, including genital examination, and receive counseling on safer sex practices and how to recognize signs and symptoms of a possible first episode of genital herpes. Source partners will also be counseled on transmission of genital herpes, and susceptible partners will be interviewed about their sexual history and practices. The source partner will be randomly assigned to take either a 500-mg tablet of valaciclovir or placebo (a pill with no active ingredient) daily for 8 months. All participants will be given diary cards to complete for a month-the source partner will record any drug side effects and the susceptible partner will record any signs or symptoms of possible HSV infection. Participants will be seen in the clinic once a month for 8 months. At these visits, source partners will 1) return unused study medication and the completed diary card; 2) discuss any adverse drug side effects experienced in the last month; 3) review medications other than the study drug taken in the last month; 4) undergo counseling on safer sex practices, transmission of genital herpes, and recognizing signs and symptoms of a first episode of genital herpes; and 5) review symptoms and recurrences of genital herpes experienced during the last month. During the final visit, they will also provide a blood sample for routine testing and possible use in future studies. Susceptible partners will 1) have a blood sample drawn for HSV testing; 2) undergo safer sex counseling; 3) review any symptoms experienced over the last month; 4) be interviewed about sexual exposure and practices; and 5) return the completed diary card. Source partners who have a recurrence of genital HSV while on the study will be asked to have their lesions cultured and will be offered open-label valaciclovir treatment. Susceptible partners who contract genital herpes from the source partner during the study will have a genital examination to verify a fist episode of genital herpes and will receive 10 days of open-label treatment with valaciclovir. Cultures will be taken from the mouth and genitals, current medical conditions will be reviewed, blood samples will be drawn on treatment days 1 and 10, and treatment side effects will be reviewed on days 5 and 10. At the end of the study, infected partners will be offered a 12-month course of valaciclovir, one 500-mg tablet daily. Participants will be followed in the clinic once every 3 months to provide blood samples, return unused study medication and the diary card, discuss any drug side effects, review medications taken besides the study drug, and review symptoms or recurrences of genital herpes. All participants will be asked to complete a questionnaire for gathering information about people with genital herpes and people at risk for the infection.
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.
