Filter by:The trial will evaluate the extended bactericidal activity of 14 consecutive days of oral administration of PA-824 at 200, 600, 1000 and 1200 mg per day in adult patients with newly diagnosed, uncomplicated, smear positive tuberculosis. A control group will receive standard TB treatment.
The aim of this study is to elucidate the prevalence of nontuberculous mycobacterial (NTM) co-infection in patients with smear positive pulmonary TB. To detect the NTM co-infection, we will perform duplex PCR targeted for mycobacterial hsp 65 gene using sputa. In addition, the clinical significance of this co-infection will be evaluated.
Tuberculosis is a highly prevalent chronic infectious disease caused by Mycobacterium tuberculosis. Cytokines are important biological mediators that regulate immune and inflammatory responses against the bacilli, witch include the acute phase response. Besides this, it becomes essential to determine markers of healing lesions, once this is currently carried out based on the clinical, radiological, and negative bacterioscopy.
Tuberculosis and vitamin D deficiency are important public health problems in India. Before the advent of effective antitubercular therapy, patients with tuberculosis were advised treatment and rest at sanatorium where sunshine was available in plenty. There have been reports associating vitamin D deficiency with tuberculosis in terms of incidence and beneficial response following addition of vitamin D to antitubercular therapy. Sputum AFB conversion rate is higher in patients with tuberculosis supplemented with vitamin D. The present study would systematically assess role of adjunct vitamin D therapy (cholecalciferol) in patients with pulmonary tuberculosis.
Estimate of clinical and microbiological efficacy of Levofloxacin (Tavanic) in combine therapy of MDR TB. Estimate of safety of Levofloxacin (Tavanic) in combine therapy of MDR TB.
This study will evaluate the effect of adding metronidazole to standard second-line therapy for tuberculosis in patients who have multi-drug resistant tuberculosis (MDR-TB) of the lungs. It will evaluate the safety and tolerability of metronidazole in combination with antituberculosis agents. Metronidazole is a drug widely used to treat bacterial and parasitic infections occurring in environments with very little oxygen such as the human colon. Nine million new cases of sputum-positive tuberculosis are diagnosed worldwide each year. Patients ages 20 and older who have symptoms of TB, who have been treated for tuberculosis but whose disease is multi-drug resistant, and who are not pregnant or breast feeding may be eligible for this study. They will be recruited in the National Masan Tuberculosis Hospital (NMTH), Masan, Republic of Korea. Patients will undergo the following tests and procedures: - Collection of sputum for counting of bacteria. - Drawing of blood for routine blood chemistry analysis; for measuring levels of metronidazole; TB lipid analysis; and for testing levels of T-cells, which are part of an immune response. - Two targeted positron emission tomography (PET) scans, each with a computed tomography (CT) scan, and five high-resolution CT scans. Patients will receive either an 8-week course of standard second-line agents plus placebo (sugar pill) or an 8-week course of standard agents plus metronidazole. The subjects, doctors and researchers will not know which patients are taking the metronidazole until after the first 2 years of the trial. A total of 60 patients will be assigned to two cohorts of 30 patients each. After 8 weeks, all patients will return to the standard of care chemotherapy, according to normal procedures at NMTH. Side effects of metronidazole commonly reported are vaginal discharge, symptoms of Candida cervicitis and vaginitis, headache, nausea and vomiting, and dizziness. Peripheral neuropathy, an abnormal condition of the nerves, may also be a side effect. The precise incidence of neuropathy is unknown but is usually related to the duration of metronidazole use. It can almost always be reversed when the drug is discontinued. Serious side effects, though rare, may include leukopenia and thrombocytopenia (disorders in the blood), seizures and other central nervous system problems, and hepatitis. This study may or may not have a direct benefit for participants. However, it is possible that patients' drug-resistant disease may be more effectively treated as a result of metronidazole. The study may help identify new methods for measuring drug effectiveness during TB studies.
The purpose of this study is to determine whether vitamin D enhances response to standard antibiotic treatment for pulmonary tuberculosis.
The purpose of this study is to determine if 30-day survival will be improved with addition of prednisone to standard tuberculosis (TB) therapy.
The purpose of this trial is to evaluate the safety, efficacy and pharmacokinetics of 100mg, 200mg , 300mg and 400mg once daily of OPC-67683, administered orally for 14 consecutive days, in patients with uncomplicated, smear-positive pulmonary TB. The four OPC-67683 treatment groups will comprise 12 patients each and the one standard therapy (Rifafour e-275) group six patients. Trial 242-06-101 is an exploratory and not a confirmatory trial and as such no hypothesis will be tested statistically. The control group, six patients treated with Rifafour, will serve as an control to confirm the microbiological assessments during the trial.
This study will evaluate the ability of 4 antibiotics to kill the bacteria that cause tuberculosis (TB). The antibiotics to be studied are linezolid, gatifloxacin, levofloxacin, and moxifloxacin. All are approved by the Brazilian health authorities to treat infections caused by germs other than TB. Seventy human immunodeficiency virus (HIV)-negative adults, aged 18-65 years, who have been newly diagnosed with pulmonary (lung) TB, will participate in this study. Study volunteers will be given one of the 4 study drugs or a comparison antibiotic, Isoniazid, which has been used around the world as a standard of care treatment for TB. Volunteers will stay in the hospital for 10 days and be given a study antibiotic 7 of those days. Blood and saliva samples will be taken. Six weeks later, volunteers will return for a final health check. All volunteers will receive 6 months of standard tuberculosis treatment.
