Filter by:Background : The toll-like receptor is an essential receptor that stimulates the innate immunity response. In tuberculosis, toll-like receptors, particularly the TLR-2, and TLR-4 are crucial in recognizing various ligands with a lipoprotein structure in the bacilli. Vitamin D deficiency leads to lower expression of these receptors, Hence the immune response against Mycobacterium tuberculosis will be altered. Various studies addressed the importance of vitamin D supplementation in pulmonary tuberculosis but the effect of vitamin D in extrapulmonary tuberculosis, particularly spondylitis tuberculosis is not sufficiently identified. Objectives: To assess the effect of oral vitamin D supplementation on the expression of TLR-2, TLR-4, and clinical outcomes in spondylitis tuberculosis patients. Methodology: This study proposes a randomized clinical trial of oral vitamin D supplementation in spondylitis tuberculosis patients. Multiple arms will be established with different doses and control groups. The outcome of interest includes the clinical outcomes, the expression of TLR-2, and TLR 4 Hypothesis : It is assumed that oral supplementation of Vitamin D will increase the activation of Toll-Like Receptors and improves the clinical condition of Spondylitis Tuberculosis patients
Organ transplant recipients are a high incidence group of tuberculosis infection, and the incidence rate is 7-27 times that of the general population. The prevention of postoperative tuberculosis infection is an important part of kidney transplant recipients postoperative follow-up. Taking reasonable tuberculosis prevention strategies for organ transplant recipients can better prevent the occurrence of postoperative tuberculosis and reduce the unreasonable use of anti-tuberculosis drugs. The previous screening methods for active tuberculosis mainly include sputum smear culture, tissue biopsy, tuberculin skin test, tuberculosis antibody, tuberculosis DNA, and chest imaging. However, there is still a lack of accurate and effective means for screening for latent tuberculosis infection. The tuberculosis interferon-γ release test has recently received more and more attention as a means of screening for potential tuberculosis infection. However, how to apply tuberculosis interferon-γ release test in clinical practice is still controversial. The investigators hope to explore the clinical application prospects and practical value of tuberculosis interferon-γ release test through this research. According to the conclusion of the retrospective study, the investigators found that the recipients with negative TSPOT result maybe don't need follow the isoniazid treatment to prevent the development of tuberculosis even though participants have clinical risk factor of tuberculosis(include past tuberculosis history, the close contact with active tuberculosis patients, an area with a high incidence of tuberculosis, abnormal chest x ray performance ). The investigators will divided the recipients with tuberculosis risk factors into three groups randomly. Of course, the invention require written informed consent. The first group with positive tuberculosis interferon gamma release assay (TSPOT) result will follow through with the treatment ,which is a daily dose of isoniazid for six months(300mg daily) after kidney transplant surgery. The second group with negative TSPOT result will not follow through the isoniazid treatment. The third group will follow through with the isoniazid treatment no matter their TSPOT results. The investigators will conduct a prospective clinical trial with the first aim of exploring the effectiveness of TSPOT results in kidney transplant recipients with clinical tuberculosis risk factors, and the second aim of exploring the benefit of the isoniazid treatment follow the TSPOT results rather than clinical risk factors.
To determine the effect of pulmonary rehabilitation on pulmonary function in non-chronic obstructive pulmonary disease patients.To determine the effect of pulmonary rehabilitation on health related quality of life in non-chronic obstructive pulmonary disease patients.Limited researches are available in non chronic obstructive pulmonary disease patients.
Tuberculosis is still global burden disease at all the word and effect on quality life of patients and affect on health authorities because the cost of medicine and health cost . - A total of 1.4 million people died from TB in 2019 (including 208 000 people with HIV). Worldwide, TB is one of the top 10 causes of death and the leading cause from a single infectious agent (above HIV/AIDS). - In 2019, an estimated 10 million people fell ill with tuberculosis (TB) worldwide. 5.6 million men, 3.2 million women and 1.2 million children. TB is present in all countries and age groups. But TB is curable and preventable. - In 2019, 1.2 million children fell ill with TB globally. Child and adolescent TB is often overlooked by health providers and can be difficult to diagnose and treat. - In 2019, the 30 high TB burden countries accounted for 87% of new TB cases. Eight countries account for two thirds of the total, with India leading the count, followed by Indonesia, China, the Philippines, Pakistan, Nigeria, Bangladesh and South Africa. ( WHO) All TB cases and 92.5% controls were zinc deficient. The odds of TB cases with deficiencies of vitamin A and zinc was 2.3 (95% CI: 1.1 to 4.8) times more likely as compared to the controls. More than 80% of all participants had below average fulfilment of energy and vitamin A intakes. (7) Zinc is necessary for intact immune health and defense against infection but there are common health problem deficiency at developing countries and so zinc needs as supplement and the second problem zinc need helper for transfer through plasma membrane so zinc ionophore is a best solution as this problem so the investigators can use zinc ionophore as helper for zinc to enter the cells for autophagy
The main purpose of the present study is to compare the diagnostic yield of different aspiration techniques in Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) in the diagnosis of hilar/mediastinal adenopathy
Utilizing the Crosstalk Among Chicoric Acid, 13-Cis Retinoic Acid(Aerosolized), Minocycline and Vitamin D as a Potent Quadrate Therapy for treating patients with Multidrug-resistant TB and patient with both Multidrug-resistant TB and COVID-19 . A double-edged sword Clinical Study I)Part of Tuberculosis Tuberculosis (TB) is a major infectious disease killer globally. It affected 10 million and killed 1.4 million people in 2019 alone. The predicted impact of the COVID-19 pandemic is an additional 190,000 TB deaths in 2020, and it is expected in the next 5 y that there will be up to a 20% increase in the global TB disease burden , stressing the critical need for new safe and effective drugs against Mycobacterium tuberculosis (Mtb). In addition, controlling multidrug-resistant TB (MDR-TB) presents a huge public health challenge . New drug discovery could require several years with no guarantee but repurposing established may be useful to treat patients with tuberculosis . Here we demonstrate that we could utilize the crosstalk among Chicoric Acid, 13-Cis Retinoic Acid, Minocycline , and vitamin D as a novel quadrate therapy against TB.Drug-resistant tuberculosis represents a global emergency, requiring new drugs. Recently Minocycline was found to be highly potent in laboratory strains of Mycobacterium TB, and 30 drug-sensitive and multidrug/extensively drug-resistant clinical strains were susceptible to clinically attainable dosages. The lung concentration-time profiles of a 7 mg/kg/day human-equivalent minocycline dosage yielded bacterial kill rates comparable to first-line antituberculosis drugs. Extracellular bacilli were destroyed directly by minocycline. Minocycline also killed intracellular bacilli indirectly through granzyme A-driven apoptosis. Furthermore, minocycline showed dose-dependent antiinflammatory effect, suggesting that it may protect tuberculosis patients against immunopathology. A study showed that M. tuberculosis induced the expression of indoleamine 2,3-dioxygenase (IDO), an enzyme involved in tryptophan catabolism, in macrophages and in the lungs of animals (mice and macaque) with active disease. In a macaque model of inhalation TB, suppression of IDO activity reduced bacterial burden, pathology, and clinical signs of TB disease, leading to increased host survival. This increased protection was accompanied by increased lung T cell proliferation, induction of inducible bronchus-associated lymphoid tissue and correlates of bacterial killing . A recent study showed that Minocycline-induced significantly inhibition of IDO expression. But Minocycline-induced inhibition of IDO expression is retinoid-dependent. The combined treatment with minocycline and retinol, however, resulted in a striking, statistically significant decrease in IDO. Co-treatment with minocycline and retinol again resulted in decreased TNF-α and IL-6 levels. A study showed that IL-6 inhibits IFN-γ induced autophagy in Mycobacterium (TB) H37Rv infected macrophages. As well as neutralization of endogenous IL-6 by anti-IL-6 antibody significantly enhances the IFN-γ mediated killing of the intracellular bacteria. Minocycline's anti-inflammatory effects are mediated through RAR signaling. Therefore, The combined treatment with minocycline and retinol is expected to effectively inhibit (TB) and its inflammatory complication, Fortunately, Retinoic Acid significantly inhibits the in vivo growth of M. tuberculosis and the development of tuberculosis. In addition to, 13-Cis RA and Chicoric Acid ( CA ) enhanced the cell surface expression of HLA-DR and CD14 molecules on U937 macrophages and prevented the growth of Mtb within macrophages. Moreover, 13-cis RA and CA, have increased NO generation compared to untreated control macrophages, significantly . Both drugs have a significant inhibitory effect on Mtb growth but CA at the highest concentration was more potent than 13-cis RA . Therefore we will use retinoic acid to induce the effect of Minocycline as well as its ability to inhibit tuberculosis in combination with CA .Recent data showed that Vitamin D support innate immune responses to Mycobacterium TB and Low vitamin D levels were associated with a 5-fold increased risk for progression to tuberculosis. Deficiency of vitamin D has long been implicated in activation of (TB) . Serum vitamin D in TB patients are lower than in healthy controls . Vitamin D has been found to speed up the clearance of (TB) bacteria from the lungs of people with multi-drug resistant TB, according to a study of 1,850 patients. It was showed that Vitamin D receptor (VDR) must form a heterodimer complex with retinoid X receptor (RXR) to regulate gene transcription. Retinol plays a crucial role in lung development and signaling the vitamin D pathway. 9-cis-retinoic acid, an active vitamin A metabolite and the ligand of RXR, assists VDR signaling and suppresses the degradation of circulating vitamin D.
The Fujifilm SILVAMP TB LAM (FujiLAM; Fujifilm, Tokyo, Japan) is a novel (not commercialized) urine based point-of-care assay to diagnose TB in HIV-positive patients. A first study using urine frozen samples has reported a higher sensitivity of this test over the currently commercialised Alere Determine TB LAM Ag assay (AlereLAM).
Objective To determine if treatment completion with a 4-month rifampin (4R) or 3-month rifapentine (P) + isoniazid (H) weekly for 12 weeks (3HP) regimens is better than with a 3-month (3HR) regimen for treatment of latent tuberculosis (TB) infection (LTBI) in patients with end stage kidney disease. Methods Design: Multicenter, prospective, parallel-group, open-label, controlled clinical trial. Study population: All adult patients with ESKD in who treatment for LTBI is prescribed at 7 hospitals. Interventions: Patients who accept participation, will be randomly assigned to one of the 3 arms: 3HR (control) (90 doses), 4R (120 doses) or 3HP (12 doses). Outcome: Proportion of participants who discontinue permanently the assigned treatment. Follow-up: Periodic assessment for permanent or temporary discontinuation, and adverse events of the assigned treatment. Sample size: 225 subjects (75 per arm) will be needed to demonstrate, if exists, a 0.16 decrease in permanent discontinuation rates in the experimental arms (4R and 3HP) with respect to the control arm (3HR), with α= 0.025, β= 0.20, and 5% expected losses, and assuming a 0.25 proportion of permanent discontinuation in the control.
Resistance to anti-tuberculosis drugs is a continually growing problem. Multidrug-resistant tuberculosis (MDRTB) is resistance to at least rifampicin and isoniazid, and extensively drug-resistant TB is additional resistance to a fluoroquinolone and a second injectable line drug. Methods currently employed in testing for resistance are inadequate and a contributing factor to the 40-50% MDR-TB treatment success rate. Current drug susceptibility testing methods are slow for most drugs, taking weeks. Rapid molecular methods such as the line probe assays, e.g. Hain GenoType MDRTBplus and sl, provide resistant calls to only a limited number of drugs, and are often less useful in smear negative patients. Molecular technologies such as sequencing can provide a comprehensive readout of drug resistance and are able to detect resistant populations at very low levels (≤1%), thus enabling individualized therapy. This can be done directly from sputum. Targeted sequencing amplifies regions of genomic DNA associated with resistance prior to sequencing. Rapid analytic software is used to process the raw sequence data, identify resistance causing mutations and provide a readout of clinically relevant information. However, the feasibility, and more importantly the impact, of this approach has not been evaluated in a clinical trial to establish proof of concept. Aim 1: To conduct a randomised controlled trial to determine the impact of sputum-based targeted sequencing in detecting resistance to second-line TB drugs compared to the current programmatic standard of care (Hain MDRTBplus/sl and adjunct phenotypic drug susceptibility testing) when used to inform of treatment for MDR-TB. Aim 2: To compare currently available drug resistant sequencing pipelines for diagnostic accuracy, sensitivity, specificity and predictive value as compared to culture based phenotypic drug susceptibility testing. Aim 3: To compare the feasibility, accuracy, turn-aroundtime, and cost implications of the above-mentioned diagnostic approaches.
