Filter by: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
The purpose of this study is to evaluate the safety, pharmacokinetics, and effects of imatinib on myelopoiesis in adults when given with and without isoniazid and rifabutin. The results of this trial will determine the imatinib dose to be studied in a subsequent Phase IIB treatment trial of imatinib as an adjunctive therapy with an antimicrobial regimen (rifabutin, pyrazinamide (PZA), isoniazid (INH) and ethambutol) for drug-sensitive TB.
Drug therapy for persons living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) co-infected with latent tuberculosis infection (LTBI) is complex. Anti-tuberculosis drugs used to treat LTBI often induce drug metabolizing enzymes that share the same metabolic pathway as antiretroviral drugs used for those living with HIV/AIDS. This study evaluates the drug-drug interaction (DDI) potential of an antiretroviral drug when co-administered with a common anti-tuberculosis regimen of drugs.
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of pravastatin adjunctive therapy when combined with the standard tuberculosis (TB) treatment regimen in adults with TB.
Isoniazid preventive therapy (IPT) reduces the risk of tuberculosis in 60%. Young children are at higher risk of developing severe forms of TB, though this can be prevented with a full course of IPT. Preliminary data indicate that 60% of eligible children start IPT, and 30% complete it. Furthermore, children can be exposed to more than one case of TB in the household. Adults exposed to TB in the household setting are not necessarily aware of their risk. Uncertainties in the decisions of staff to prescribe IPT and limited health literacy among caretakers and families contribute to this. The investigators will determine the efficacy of an intervention package to increase IPT adherence and completion among children < 5 years old exposed to TB in the household. The investigators will assess the efficacy of the intervention by 1) measuring IPT completion at 6 months after treatment initiation and by 2) determining adherence to IPT by measuring isoniazid in urine at weeks 2, 8 and 24 in a random cluster sample of 10 health facilities and 20 control facilities with 10 children included in each facility (100 in intervention and 200 in control). The investigators will measure fidelity and reach, and acceptability among caretakers and health staff. The intervention package will consist of: 1) educational booklet for caretakers explaining why IPT needs to be given 2) a children's storybook, with weekly installments, over the 6-month course of IPT as a non-monetary incentive and 3) short messages services (SMS) reminders delivered to the caretaker for the weekly pick-up In September 2020, the protocol was updated to adapt to the COVID19 situation in Lima. One of the secondary outcome (isoniazid concentration in urine) was cancelled and the full intervention (educational booklet, weekly children storybook and weekly SMS) is now delivered through WhatsApp.
This is a double-blind, randomized (in 3:1 ratio -vaccine : placebo) study to assess the safety, reactogenicity and immunogenicity in healthy, BCG vaccinated adults.
Previous studies have shown that a small incentive can have a large impact on health behaviors like vaccinating children. New Incentives, an international non-governmental organization (NGO), aims to boost demand for immunization by offering cash incentives to caregivers who have their child vaccinated at a program clinic. In collaboration with New Incentives, IDinsight is conducting a study to see whether this approach will increase immunization in North West Nigeria. This study aims to investigate whether giving cash to caregivers in North West Nigeria who bring their infants to receive vaccination against common infections (tuberculosis, diphtheria, tetanus, pertussis, hepatitis B virus (HBV) infection, Haemophilus influenzae Type B (Hib), pneumococcal bacteria, measles, rotavirus, polio, yellow fever) increases the proportion of children who are immunized. The study's main hypothesis is that New Incentives' program will increase the percentage of children immunized with BCG, any PENTA, or Measles 1 by an average increase of at least 7-percentage points across all program clinics that share a similar profile to the clinics New Incentives will operate in at scale. The study is taking place in Jigawa, Katsina, and Zamfara States between August 2017 and January 2020.
