  • VDOT for Monitoring Adherence to LTBI Treatment

    open to eligible people ages 13 years and up

    The three-month short-course treatment with isoniazid [H] and rifapentine [P] (3HP) recently recommended by the Centers for Disease Control and Prevention could dramatically increase the number of persons starting and completing treatment for latent tuberculosis infection (LTBI), but TB providers nationwide are hamstrung by the requirement that 3HP only be administered by directly observed therapy (DOT) in which patients are watched taking each medication dose in-person. We developed a novel mHealth application that allows patients to make and send videos of each medication dose ingested that are watched by healthcare providers via a HIPAA-compliant website to remotely monitor LTBI treatment adherence (Video DOT [VDOT]). This study will determine whether monitoring patients with VDOT achieves higher treatment completion rates and greater patient acceptability at lower cost than clinic-based in-person DOT.

  • Nurse-Led Community Health Worker Adherence Model in 3HP Delivery Among Homeless Adults at Risk for TB Infection and HIV

    Sorry, not yet accepting patients

    Tuberculosis (TB) is the prototypical disease of poverty as it disproportionately affects marginalized and impoverished communities. In the US, TB rates are unacceptably high among homeless persons who have a 10-fold increase in TB incidence as compared to the general population. In California, the rate of TB is more than twice the national case rate and recent TB outbreaks have been alarming. Among persons with active TB disease, over 10% die during treatment, with mortality being even higher among homeless persons with TB. While TB can be prevented by treating TB infection (TBI) before it develops into infectious, symptomatic disease, individual factors such as high prevalence of psychosocial comorbidities, unstable housing and limited access to care have led to poor adherence and completion of TBI treatment among homeless persons. Given the complex health disparity factors that affect TBI treatment adherence among homeless persons, this study will assess the feasibility of a theoretically-based novel model of care among persons with TBI and complex chronic illnesses. This study will evaluate an innovative, community-based intervention that addresses critical individual level factors which are potential mechanisms that underlie health disparities in completing TBI treatment among the predominantly minority homeless. The study hypothesis is that improving these conditions, and promoting health by focused screening for TBI, and early detection and treatment for these vulnerable adults will improve TB treatment completion and prevent future TB disease. The proposed theoretically-based health promotion intervention focuses on: 1) completion of TBI treatment, 2) reducing substance use; 3) improving mental health; and 4) improving critical social determinants of TB risk (unstable housing and poor health care access) among homeless adults in the highest TB prevalence area in Los Angeles. A total of 76 homeless adults with TBI will receive this program which includes culturally-sensitive education, case management, and directly observed therapy (DOT) delivery of medication among patients who have been prescribed 3HP (12 weeks treatment for latent TB infection) by a medical provider. This study will determine whether this intervention can achieve higher completion rates than the 65% completion rate among homeless persons reported by previous TB programs.

  • TBTC Study 31: Rifapentine-containing Tuberculosis Treatment Shortening Regimens

    Sorry, in progress, not accepting new patients

    The purpose of this study is to determine whether one or two four-month regimens of tuberculosis treatment are as effective as a standard six-month regimen for treatment of pulmonary tuberculosis (TB). All three regimens are administered daily, seven days each week, with direct observation of each dose by a health-care worker at least five of the seven days of each week. The standard six-month regimen is two months of isoniazid, rifampin, ethambutol, and pyrazinamide followed by four months of isoniazid and rifampin. The first short regimen is a single substitution of rifapentine for rifampin: two months of isoniazid, rifapentine, ethambutol, and pyrazinamide, followed by two months of isoniazid and rifapentine. The second short regimen is a double substitution of rifapentine for rifampin and moxifloxacin for ethambutol: two months of isoniazid, rifapentine, moxifloxacin, and pyrazinamide, followed by two months of isoniazid, rifapentine, and moxifloxacin. Target enrollment is 2500 participants. Each study participant will remain in the study for 18 months in order to include at least 12 months of evaluation of whether the participant's TB recurs.
