Filter by:The Options for Delivering Isoniazid-Rifapentine (3HP) for TB Prevention (3HP Options Implementation Trial) study will be a three-arm, open-label, parallel, randomized trial. This hybrid effectiveness-implementation trial will be conducted among people living with HIV infection (PLHIV) enrolled in HIV/AIDS care at the Mulago Immune Suppression Syndrome (i.e., HIV/AIDS) clinic in Kampala, Uganda. The overall objective of this study is to identify a patient-centered delivery strategy that will facilitate acceptance and completion of a three-month (12-dose) regimen of weekly rifapentine (RPT) and isoniazid (INH) by PLHIV enrolled in routine HIV/AIDS care in a high HIV/TB burden country. The primary outcome will be acceptance and completion of 3HP. Additional objectives will be to evaluate the implementation and cost-effectiveness of each delivery strategy.
The primary objective of this clinical research study is to demonstrate performance of the normalized TB specific lymphocyte response in identifying patients with active TB disease. The secondary exploratory objective is to demonstrate that active TB cannot be identified using an antigen-to-mitogen ratio derived from an ELISA-based IGRA.
Traditionally, peritoneal tuberculosis has been classified as wet-ascitic, dry-plastic type and fibrotic -fixed types. there is substantial overlap between these definitions and the clinical implication of the categorisation into the three patterns is unclear. The clinical presentation will be used to divide participants into 1) Abdominal distension dominant disease or 2) Pain Dominant and/or 3) Obstruction dominant peritoneal tuberculosis. The radiological findings between these groups will be compared if findings on radiology are discriminative of these three patterns of presentation.
LASER-TBM is a parallel group, randomized, multi-arm phase IIa trial evaluating the safety of increased dose rifampicin (RIF) plus linezolid (LZD), with or without aspirin (ASA), for the treatment of HIV-infected adults with tuberculous meningitis (TBM). The study will recruit 100 HIV-infected adults with TBM across four sites in South Africa. The primary endpoint is the occurrence of solicited treatment-related adverse events. Secondary endpoints include death and disability (including neurocognitive impairment), radiological outcomes, and the occurrence of immune reconstitution inflammatory syndrome (IRIS). A nested pharmacokinetic (PK) substudy aims to: 1. Describe the plasma and cerebrospinal fluid (CSF) PK of LZD and high dose RIF. 2. Evaluate the relationship between drug exposures, toxicity and efficacy. 3. Compare exposures between intravenous and oral RIF administration. 4. Investigate the impact of high dose RIF on LZD and dolutegravir (DTG).
The lack of data relating to the DDI between ATV and RIF is a major limitation to the use of ATV in patients who require treatment for TB. The VirTUAL Workpackage 2 will explore the necessary dose escalation required to overcome this interaction in non-pregnant HIV-infected adults who are virologically suppressed on bPI-based ART, and who are administered RIF as a study drug, not as part of a full TB treatment regimen. As the specific objective of WP2 is to define the dose of ATV, participants taking an alternative bPI will be transitioned to ATV for the duration of that study. However, to extrapolate the results of this study to special populations such as pregnant and postpartum women, children and adolescents and those with other 'special' characteristics such as obesity (BMI >30 Kg/m2) or malnutrition (BMI <18.5 Kg/m2) we propose to undertake sparse sampling for pharmacokinetic analysis from individuals who require ATV-based ART for their clinical care. Sparse PK data will be obtained opportunistically from participants in the 'special populations' defined above who are receiving ATV as part of their routine clinical care. Subjects will be identified from clinics including the Joint Clinical Research Center (JCRC) and Infectious Diseases Institute (IDI), Kampala, and from sites including Groote Schuur Hospital and Gugulethu Community Health Centre, Cape Town. The ATV/r data from "special populations" will enable validation and refinement of both the PBPK model (WP1) and the pop-PK models (WP4) of the VirTUAL consortium.
Thalassemia becomes one of global health issue and so does Indonesia. In 2015, more than 7600 children were diagnosed as this hemoglobin genetic disease wherein anemia and lifetime blood transfusion contribute to their morbidity and mortality in Indonesia. Major β-Thalassemia is the most common type found. However, along with disease progression and age, iron accumulation and dysregulation becomes the most common complication exist. In cellular level, this condition results in cell and tissue damage especially immune cells and promotes favor condition for siderophilic bacteria such as Mycobaterium tuberculosis (Mtb) to growth rapidly. Severe infection becomes the second most cause of death in thalassemia-β major patients. Tuberculosis (Tb) remains the global health issue especially in developing countries. Based on World Health Organization (WHO) report on 2015, Indonesia is the second highest burden of TB in the world. Both of adaptive and innate immune system plays important role in Mtb recognition and eradication. However, immune cells mechanism and activity in response to Mtb infection during iron accumulation condition on thalassemia-β major patients may be altered therefore need for further study. Macrophage is an adaptive immune cell, has a pivotal role on circulating-iron regulation and serves as Mtb host cell. To understand macrophage activity on thalassemia-β major patients can be studied by monocyte characteristic stimulated by Mtb antigen and evaluated by its differentiation into three subsets based on CD14 and CD16. Mtb antigen presentation is identified by HLA-DR expression on monocyte membrane. Vitamin D is one of the most affected micronutrients on major β-thalassemia patients, yet it has immunomodulatory effect on immune system. Recent finding of vitamin D receptor (VDR) expressed in monocyte strongly convince that vitamin D should be maintained in major β-thalassemia patients where it is found lower in these patients. Thus, this original and true report aimed to declare that the research activity has finished and the data has been elaborated. Future plan is developing the original article based on the research finding corroborating the previous knowledge and innovative suggestion for the quality of thalassemia.
A prospective interventional study was conducted in Services Instituton of Medical Sciences all patients who underwent emergency laparotomy from 2008-2018 due to abdominal tuberculosis. Data were analyzed using SPSS version 21
This trial will evaluate whether empirical treatment against cytomegalovirus and tuberculosis improves survival of HIV-infected infants with severe pneumonia.
TB043 is a clinical challenge trial primarily to evaluate the safety of BCG challenge administered by the aerosol inhaled route in healthy, BCG naive (Group 1-7) as well as historically BCG vaccinated UK adults (Group 8) . The trial will also look to evaluate and compare the amount of BCG recovered from the lungs as various points after challenge.
