Promoting Adherence to TB Regimens in Latino Adolescents Clinical Trials Resources presented on Clinical Trials Search isn't meant to be a substitute for qualified health advice, visits or professional assistance with a real medical. We aren't doctors. Always consult your mD about Promoting Adherence to TB Regimens in Latino Adolescents conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. Promoting Adherence to TB Regimens in Latino Adolescents Clinical research trials and Promoting Adherence to TB Regimens in Latino Adolescents health trials occur in a lot of of places throughout the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectivity of new does drugs. The role of the studies / projects is to resolve certain human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector corporations to detect remedies for all varieties of circumstances, such as Promoting Adherence to TB Regimens in Latino Adolescents. Promoting Adherence to TB Regimens in Latino Adolescents Clinical Trials and other clinical trials allow volunteers to obtain health treatment choices before they are available to the general public. Most times the human subjects recieve professional assistance for free of charge, and every now and again they are paid for their time. Sometimes there is a cost for a Promoting Adherence to TB Regimens in Latino Adolescents clinical trial. Human subjects frequently get the finest healthcare available for their Promoting Adherence to TB Regimens in Latino Adolescents condition. Risks are a reality, however, and may include extra or frequent physician visits, medical dangers (possibly life-threatening), and/or the treatment being uneffective. Trials are federally governed with strict guidelines to protect clinical trials patients.

Promoting Adherence to TB Regimens in Latino Adolescents
For Condition: Tuberculosis,Lung Diseases
Status: Completed
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: To test a public health model of screening, preventive isoniazid treatment, and adherence counseling plus medical education of primary care clinicians to enhance their skills and attention to TB control. Also, to test a behavioral adherence intervention for Latino adolescents with latent disease and a medical education program designed to enhance primary care (community clinic) practitioners' treatment of active and latent TB infection.
Details: BACKGROUND: Tuberculosis was on the decline from the mid 1950s until the mid 1980s; however, the United States is now experiencing a resurgence of tuberculosis. In 1992, approximately 27,000 new cases were reported, an increase of about 20 percent from 1985 to 1992. Not only are tuberculosis cases on the increase, but a serious aspect of the problem is the recent occurence of outbreaks of multidrug resistant (MDR) tuberculosis, which poses an urgent public health problem and requires rapid intervention. Control programs involve two major components. First, and of highest priority, is to detect persons with active tuberculosis and treat them with effective antituberculosis drugs, which prevents death from tuberculosis and stops the transmission of infection to other persons. Treatment of active tuberculosis involves taking multiple antituberculosis drugs daily or several times weekly for at least six months. Failure to take the medications for the full treatment period may mean that the disease is not cured and may recur. If sufficient medications are not prescribed early and taken regularly, the tuberculosis organism can become resistant to the drugs, and the drug resistant tubercuosis then may be transmitted to other persons. Drug resistant disease is difficult and expensive to treat, and in some cases, cannot be treated with available medications. The second major goal of control efforts is the detection and treatment of persons who do not have active tuberculosis, but who have latent tuberculosis infection. These people may be at high risk of developing active tuberculosis. The only approved treatment modality for preventive therapy requires treatment daily or twice weekly for a minimum of six months, and many patients do not complete the full course of therapy. Public and patient programs are needed to increase the awareness of the problems associated with tuberculosis control. The study is part of the NHLBI initiative "Behavioral Interventions for Control of Tuberculosis" . The concept for the initiative originated from the National Institutes of Health Working Group on Health and Behavior. The Request for Applications was released in October, 1994. DESIGN NARRATIVE: To extend the proposed model to most community clinic settings, the investigators are demonstrating outcome effectiveness as well as cost effectiveness in relation to the costs of failing to control latent TB in this population. Public school adolescents are screened and 300 PPD positive male and female Latino youth (13-18 years) are assigned at random to either usual medical treatment, usual medical treatment plus non-directed (attention control) counseling, or medical care plus behavioral adherence counseling. Concurrently participating clinic personnel receive training in TB control. The primary specific aims are to determine whether behavioral counseling increases clinic attendance and adherence to prescribed isoniazid medication relative to controls, and to determine if training increases professionals' knowledge and practice of TB screening and control treatment. Pill count and reported estimates of adherence are verified by random urine assays. Repeated measures analyses are used to assess the effects of professional training. Exploratory analyses identify correlates of adherence, and cost effectiveness analyses assess the relative costs of screening and treatment compared to the costs of not controlling TB.
