This study is being conducted to determine if losartan, an angiotensin receptor blocker (ARB), is safe and effective in the treatment of posttraumatic stress disorder (PTSD) symptoms. The study is also intended to determine if certain genetic markers are useful in predicting PTSD symptom reduction with losartan. Approximately 160 subjects with chronic PTSD ages 18-65 will participate in this study across five sites. Subjects will be assigned by chance to take either flexibly dosed losartan (up to a maximum dosage of 100 mg) or placebo (which resembles the study drug but has no active ingredients), once a day for 10 weeks. Furthermore, it is hypothesized that CC homozygotes for rs4311 SNP in the ACE gene will have a superior response to losartan on PTSD symptoms compared to T carriers.
NCT01109407
Background: \- Multiple myeloma is a type of cancer that affects white blood cells and has a poor long-term survival rate. Two other types of cancer, monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma (SMM), may eventually progress and develop into multiple myeloma. Researchers are interested in collecting samples from individuals who have been diagnosed with MGUS and SMM to study possible risk factors for developing multiple myeloma. Objectives: \- To study risk factors that may cause MGUS and SMM to progress to multiple myeloma. Eligibility: \- Individuals at least 18 years of age who have been diagnosed with either MGUS or SMM but do not have multiple myeloma. Design: * Participants will be examined by study researchers at the initial visit, at 6 months following enrollment, and every 12 months for a maximum of 5 years. * The following tests may be performed: (1) blood and urine tests, (2) bone marrow aspiration and biopsy, (3) imaging studies, and (4) a skeletal survey (a series of skeletal X-rays of the skull, spine, pelvis, ribs, shoulders, upper arm, and thigh bones). * Treatment will not be provided as part of this protocol. - Participants will remain on the study for 5 years, or until their MGUS or SMM progresses to multiple myeloma requiring treatment.
