Mycobacterium tuberculosis (M. tuberculosis) infection is still a problem that cannot be overcome in Indonesia. In 2018 the number of tuberculosis (TB) sufferers in Indonesia reached more than 850/100,000 population, an increase around 20% from the previous year's incidence. One of the highest number of cases is in East Java Province, which is 38% of the total number of new TB cases in Indonesia. Extrapulmonary tuberculosis (EPTB) according to WHO classification criteria is an M. tuberculosis infection that occurs in tissues and organs outside the lung parenchyma. The incidence rate in Indonesia reaches 1-5% of the incidence of TB thus EPTB may often be forgotten. However, the diagnosis, therapy and monitoring post treatment in EPTB remains difficult to do. The focus of this research is tuberculous lymphadenitis (TB), due to 50% of EPTB cases in Indonesia was lymphadenitis TB. The risk factors for EPTB are immunocompromised conditions, such as HIV infection or comorbid conditions such as chronic kidney disease (CKD) and diabetes mellitus, but the mechanism of EPTB homing is still unclear. The mechanism of EPTB homing, especially TB lymphadenitis, really needs to be known for the development of diagnostics and therapy as well as preventing the occurrence of TB lymphadenitis. The importance of this research is to obtain compounds from the human immune response that can be developed as diagnostic markers and therapeutic targets for tuberculosis infection, especially TB lymphadenitis. Activated macrophages containing M. tuberculosis are carried by lymph flow to lymph nodes, where there is deposition of antigen-antibody complexes which then activate CC Chemokine Receptor-2 (CCR2) on lymphocytes, which are the primary receptors for Chemokine (CC motif) ligands ( CCL)-8 and CCL5, proteins expressed on macrophages containing M. tuberculosis. Activation of CCR2 increases the production of IL-10(10). IL-10 has been responsible for decreasing the secretion of TNF-, IFN-γ, and IL-1β (11). IFN-γ affects the process of M. tuberculosis elimination and the success of TB therapy, so that IL-10 is responsible for the failure of macrophages to eliminate M. tuberculosis. IL-10 also binds to Signal Transducer and Activator of Transcription 3 (STAT3) and STAT3 increases the release of Suppressor of Cytokine Signaling 3 (SOCS3). SOCS3 interferes with IFN-γ signaling for CCR2 recognition of M. tuberculosis-containing macrophages. On the other hand, the mechanism of T lymphocytes and macrophages that activate pro-inflammatory mediators (TNF-, IFN-γ, and IL-1β) and the association of IL-10 activation on STAT3, SOCS3 and CCR2 expression in the incidence of EPTB, especially TB lymphadenitis without TB infection remains unknown.
Tuberculosis (TB) is a preventable and curable disease mostly affecting lungs and caused by the bacteria called as Mycobacterium Tuberculosis (MTB). It is estimated that approximately 10 million people are diagnosed with TB every year in the world and 1.7 billion people are infected by MTB and at risk in terms of the development of the disease. Contacted person is the one who shares the same environment with the patient suffering from contagious TB and is exposed to MTB bacilli. Today, the aim of the TB control and prevention programs is to determine the active TB patients and provide cure by healing and also to screen those contacted with the TB patients and determine whether or not they have latent TB infection and treat them and to detect the active cases among the contacts. In the current guidelines, the importance of screening all the contacts of the patients with pulmonary TB and applying a protective treatment for the household in terms of community health care is emphasised. For this reason, it is of prime importance to perform contact screening of the relatives of the TB patients and apply protective treatment. The patients receiving TB and TB protection treatment need to use medicine regularly for at least six months. It is highly important to adherence this period for the success of the treatment. However, it has been reported in the literature that the rate of nonadherence to the TB treatment varies between 20-80% and the nonadherence to the TB treatment is the most serious barrier in the control of the disease. İncomplete treatment may result in long-lasting infection, drug resistance, relapse, and death. In the litareture, it has been stated in the study conducted with the individuals with some chronic diseases that tele-follow-up is effective in providing the self-care agency of patients and the cognitive-social adaptation. It has been reported that some problems emerge especially in the TB patients such as the interruption of treatment, forgetting medication (24.5%), side-effects of drugs, (23.3%), symptomatic recovery (19.5%), failure to know the necessity of completing the life cycle of drugs by most of patients and not receiving adequate training and these problems may be managed more effectively by tele-follow-up. As is known, nurses are involved in all the processes of protecting-promoting the health of the individuals, families and society and their recovery in case of disease. Moreover, providing the protective treatment by performing the required screening for treating TB patients, their follow-up and preventing the development of disease in contacted ones has a vital importance in preventing the spread of TB in the society. Nurses may follow the findings of patients, obtain information about the process, produce information and transmit information with this system (reporting drug changes, performing training follow-up of patients etc.). In the literature, it has been emphasised that tele-mobile nursing services is a cost-effective method since it decreases the hospitalisation rate and period of the TB patients. Accordingly, the main aim of this study is to assess the effect of the training and the telephone follow-up provided by the nurse for the TB patients and contacts on the medication adherence.
The purpose of this study is to conduct a multi-country, multi-site, epidemiologic study designed to assess the proportion of interferon gamma release assay (IGRA) positivity, at site level, and to build capacity to conduct a future TB vaccine efficacy study.
A Phase 4 operational study to assess the effectiveness, feasibility, acceptability, and cost effectiveness of the GeneXpert MTB/XDR (Xpert XDR; Cepheid) assay for rapid triage-and-treatment of DR-TB-A multi-centre, multi-country prospective cohort study
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.
This is a randomized, double-blind, parallel-controlled study, for evaluation of safety and immunogenicity of three doses of an inactivated COVID-19 vaccine (CoronaVac) in pulmonary tuberculosis patients aged 18-75 years. 200 tuberculosis patients and 40 healthy adults aged 18-75 years will be recruited in this study. Of them, 200 pulmonary tuberculosis patients will be randomized at a 1:1 ratio to receive two doses of standard dosage CoronaVac plus one dose of double dosage CoronaVac or two doses of standard dosage CoronaVac plus one dose of standard dosage CoronaVac at a schedule of 0, 28, 56 days, respectively. Other 40 healthy subjects served as an external control group will be vaccinated with two doses of standard dosage CoronaVac at a schedule of 0, 28 days. The occurrence of adverse events within 28 days after each dose vaccination and serious adverse events within 3 months after full vaccination will be observed. In addition, blood samples will be collected on day 0 before the first dose and 28 days and 3 months after the last dose vaccination in all participants and 28 days after second dose in pulmonary tuberculosis patients. Each subject will remain in this study for 5 months (healthy group) or 6 months (tuberculosis group).
Tuberculosis (TB) is a global epidemic and for many years has remained a major cause of death throughout the developing world. Zambia is among the top 30 TB/HIV high burden countries. Chest X-ray (CXR) is recommended as a triaging test for TB, and a diagnostic aid when available. However, many high-burden settings lack access to experienced radiologists capable of interpreting these images, resulting in mixed sensitivity, poor specificity, and large inter-observer variation. In recognition of this challenge, the World Health Organization has recommended the use of automated systems that utilize artificial intelligence (AI) to read CXRs for screening and triaging for TB. In this study, we primarily evaluate the performance of our AI algorithm for TB, and secondarily for Abnormal/Normal.
