Filter by:The purpose of this randomized trial is to verify if leprosy patients, despite of their classification, can be treated with the same regimen without compromising patient cure and acceptability of the treatment. At present, patients classified as multibacillary leprosy are treated for 12 months with three drugs, and patients classified as paucibacillary leprosy are treated for 6 months with two drugs. The study is going to test a unified regimen for paucibacillary and multibacillary patients by treating leprosy patients with three drugs for 6 doses.
The purpose of the study is to see if new methods can be used to determine why Multidrug Therapy (MDT), used to cure leprosy patients effectively for twenty years, is not as effective against Leprosy in the Philippines. Researchers do not know how people get infected with leprosy or what causes the disease to relapse after cure with adequate MDT. Blood, skin scrapings, nasal swabs and biopsies, will be collected from leprosy patients to perform tests related to the detection of the disease and the germ. The tests will be used to find out if the bacteria in the body are related to the bacteria found in other patients or contacts. This will help the researchers to know where these bacteria come from, and to see how they spread. Other tests will be performed to see if the bacteria can be killed by two common medicines given to leprosy patients. Study participants will include individuals age 18 and older presenting to Leonard Wood Memorial for the diagnosis and/or relapse of leprosy.
The purpose of this study is to determine what factors contribute to the continued incidence of leprosy in Colombia. Study participants will include volunteering and consenting individuals, older than 4 years of age, representing three study groups: 1. healthy persons with no known contact with leprosy patients 2. patients reporting at Instituto Colombiano de Medicina Tropical-CES and Impresa Social del Estado Sanatorio Agua de Dios with a new diagnosis of leprosy or relapse of leprosy 3. household contacts of leprosy patients described in group 2. Blood, nasal swabs, slit skin smears, and biopsies will be taken from the volunteers to learn the strains of leprosy-causing bacteria in the area, the immune responses (body's response to disease) in local residents against the bacteria, and the pattern of leprosy transmission. Individuals will participate in this study for 1-10 days, and the study will last for 3 years.
The purpose of this study is to see how healthy people and leprosy patients react to 2 new skin tests for detecting leprosy. The study will evaluate the new skin tests that may aid in measuring the number of people exposed to leprosy and enable its diagnosis and treatment at an earlier stage. Participant's ages 18-60 living in Kathmandu, Nepal will be enrolled. Stages A and B of the study will use the skin test in healthy volunteers. Stage C will use the skin test in high risk volunteers (including individuals with leprosy), healthy individuals in contact with leprosy patients and individuals with tuberculosis (TB, lung disease). Study procedures will include injections, physical exam, and blood testing. Injection sites will be checked several times during the participant's study involvement (5 hours of time spread over approximately 1 month). Volunteers screened for the study, which have leprosy or tuberculosis will be treated or referred for treatment.
