NCT00177970
In this trial, eligible patients will be randomly assigned to receive a single dose of 400 mg/kg of IVIG or a normal saline infusion as placebo over 4-6 hours, in addition to their usual medications for CDAD. We expect to enroll approximately 40 patients over a period of two years from UPMC Shadyside Hospital, McKeesport Hospital, and St. Margaret's Hospital who are unresponsive to standard antimicrobial therapy for CDAD. During the course of this study we expect that IVIG group compared with placebo group will have fewer number of stools per day (\< 3 per day). Secondary endpoints will include normal WBC count, normal body temperature, 75% reduction in abdominal pain / tenderness, and decrease in length of hospital stay. Subjects will sign a written informed consent prior to any study procedures. Patients will be monitored closely during the infusion of the study medication and will continue to be monitored on a daily basis up to the time of discharge. Data collection will include vital signs, CBC, stool C. difficile cytotoxin assay, and stool counts before and after therapy.
NCT00343603
The purpose of this research study is to evaluate an investigational system that may allow doctors to show images of the different parts inside the eye that show greater detail than current equipment can produce.
NCT00393874
The purpose of this research study is to evaluate and compare the effects of experimental treatments aimed at improving insomnia and nightmares in men and women military veterans between the ages of 18 and 60 years old, and who have a condition called Posttraumatic Stress Disorder. Insomnia refers to difficulty falling or staying asleep, although enough time is allowed for sleeping. Insomnia is also associated with daytime consequences, such as lack of energy, irritability, and difficulty concentrating. Nightmares are bad dreams that may or may not awaken the sleeper, and that cause discomfort during the daytime. Chronic Posttraumatic Stress Disorder (PTSD) refers to symptoms that occur after someone experienced or witnessed a life-threatening event, and that persist for three months or more after the event. Symptoms include flashbacks, nightmares, feelings of detachment from others, sleep disturbances, irritability, anxiety, and efforts to avoid people and places associated with the life-threatening event. These symptoms occur after a life-threatening event. Symptoms that persist for more than one month indicate the presence of PTSD. In the present study, we will study people with chronic PTSD, which refers to PTSD symptoms that persist for more than 3 months. Efficacy of a treatment is defined as the capacity to produce the desired effects. In this study, we will evaluate and compare the capacity of two active experimental treatments to reduce insomnia and nightmares associated with PTSD, and one inactive intervention, called a placebo, for people who continue to have sleep difficulties despite receiving treatment with an antidepressant medication called a selective serotonin reuptake inhibitor (SSRI, like Prozac, Paxil, Zoloft, Celexa). The two active experimental treatments are a medication, prazosin, and a brief behavioral intervention, which involves exercises and techniques to reduce nightmares and improve sleep quality. Prazosin is an approved medication by the Food and Drug Administration (FDA) against high blood pressure, but is not FDA-approved for posttraumatic insomnia and nightmares.
