The incidence of tuberculosis has decreased over the last 2 years on the national territory (6.4/100,000 inhabitants) but remains twice as high in Ile de France where it is increasing with an increase of almost 10% in the number of cases. reported between 2015 and 2017 . the notification rate of tuberculosis disease for the year 2020 was 14.3 cases per 100,000 inhabitants (i.e. 1757 cases declared) which is more than double that found at the national level . As the disease is multifocal, patients are likely to be hospitalized in different departments with variable care and compliance support offered. One of the major issues is compliance with treatment. Indeed, INVS data (2008-2014) report a percentage of treatment completed in pulmonary tuberculosis of 73% . Among these cases, 20% had a potentially unfavorable outcome, including 45% lost to follow-up, which creates a risk of relapse and contagiousness for those around them. The latest data reported in 2022 over the period 2014-2018 seem to show an increase in treatment completeness but completeness remains variable from one region to another and from one year to another Using Public Health France data, the investigator were able to collect the proportion of completeness of treatment at Saint Antoine hospital, which is 60% over the period 2014-2016 (Public Health France, unpublished data). In more recent work carried out within the department retrospectively between 2019-2021, the investigator compared treatment outcomes depending on whether or not patients benefit from ETP support and it is 66% among patients without it. benefited, thus confirming the data from Public Health France over a more recent period.. In this context, several other studies have shown the interest of a therapeutic education program on the completeness of the treatment.
NCT07520448
The goal of this interventional study is to evaluate three tuberculosis (TB) screening and prevention strategies in prisons in Paraguay. The main questions it aims to answer are: * Which strategy is more effective for reducing the incidence rate of active TB? * Which strategy is more effective for reducing the TB infection rate? * Are these strategies safe, feasible, and cost-effective in prison settings? Researchers will compare three cluster-based, non-randomized programmatic strategies implemented in three prisons. These strategies differ in the frequency of screening, the diagnostic methods used, and the approach to tuberculosis preventive therapy (TPT). Participants will: * undergo informed consent and clinical evaluation * receive TB screening through symptom assessment, chest digital X-ray with CAD, and rapid molecular testing, depending on site strategy * undergo IGRA testing and preventive therapy assessment, depending on the assigned strategy * be followed for 18 months, with screening rounds every 6 months or annually depending on the prison
NCT03828201
Multidrug-resistant tuberculosis (MDR-TB) is tuberculosis (TB) that is resistant to at least isoniazid and rifampicin, the two most important anti-TB drugs. It occurs in 3.6% of newly diagnosed TB patients in the world and 17% of patients who have been previously treated. In 2017, approximately 600,000 people were estimated to have acquired MDR-TB. However, only 25% of persons with MDR-TB were diagnosed and started on treatment, reflecting inadequate diagnostic capacity and lack of TB treatment capacity. In this multicenter, randomized, partially blinded, four-arm, phase 2 study, the investigators will examine the efficacy and safety of an all-oral regimen of bedaquiline, delamanid, levofloxacin, linezolid, and clofazimine given for 16, 24, 32 or 40 weeks

NCT07511244
This clinical trial aims to evaluate the safety and efficacy of spinal cord stimulation (SCS) in treating patients with urinary and bowel dysfunction after spinal cord injury (SCI). SCI is a highly disabling condition that can lead to sensory, motor, and autonomic nervous system dysfunction below the injury level. Neurogenic bladder and bowel dysfunction are common sequelae of SCI, seriously affecting patients' quality of life. Currently, clinical treatments can only partially alleviate urinary and bowel dysfunction, and more effective therapeutic approaches are still needed. Existing clinical studies have shown that SCS is gradually being applied to treat neurogenic bladder and bowel dysfunction in SCI patients. SCS can significantly improve urinary efficiency, bladder capacity, compliance, and detrusor pressure in SCI patients, thereby enhancing their quality of life. The main questions this study aims to answer include: 1. Can this protocol help patients restore partial urinary and bowel function? 2. Besides the restoration of partial urinary and bowel function , can the SCS therapy could also help patients to restore the walking function. Patients with urinary and bowel dysfunction more than 6 months after spinal cord injury will undergo epidural spinal stimulation electrode implantation surgery two weeks after functional assessment. Then the parameter optimization and rehabilitation will last for 6 months. The follow-up records and assessments will be conducted monthly at 2, 4, and 6 months after surgery.
NCT07502612
This pilot study investigates the effects of reducing pain medication including opioids and anticonvulsants, on spinal cord sensitivity during closed-loop spinal cord stimulation (SCS). Patients with Persistent Spinal Pain Syndrome Type 2 (FBSS/FNSS) will undergo a standard 21-day SCS trial with the Evoke closed-loop system, followed by permanent implantation if successful. Neurophysiological responses (activation plots, conduction velocity, chronaxie, rheobase) and patient-reported outcomes (VAS, activity, sleep, medication intake) will be collected during the trial and up to 6 months after implantation. The goal is to evaluate the relationship between medication tapering and spinal cord sensitivity

NCT07485868
Despite being a curable and preventable disease, tuberculosis still represents a major global health problem. It is estimated that 10.8 million people contracted tuberculosis in 2023, with an incidence of 134 per 100,000 inhabitants. In 2023, there were 1.25 million deaths, confirming this disease as a leading cause of death and the leading cause of death from a single infectious agent. It is a disease that primarily affects adults in their most productive years, with significant repercussions on family budgets. The aim of this study is to identify and characterize the demographic, epidemiological, microbiological, clinical, and radiological variables of the tuberculosis population that has come to our hospital's attention, as an exemplary population in a low-endemic setting. This study also aims to develop a tuberculosis risk score aimed at early differentiation between patients requiring respiratory isolation and those with negligible tuberculosis risk, and to improve diagnostic accuracy.

NCT06192160
A5409/RAD-TB is an adaptive Phase 2 randomized, controlled, open-label, dose-ranging, platform protocol to evaluate the safety and efficacy of multidrug regimens for the treatment of adults with drug-susceptible pulmonary tuberculosis (TB). A5409 hypothesizes that novel regimens for the treatment of pulmonary tuberculosis will result in superior early efficacy, as determined by longitudinal mycobacteria growth indicator tube (MGIT) liquid culture time to positivity (TTP) measurements over the first 6 weeks of treatment, and will have acceptable safety and tolerability over 8 weeks of treatment relative to standard of care \[(SOC) isoniazid/rifampicin/pyrazinamide/ethambutol (HRZE)\]. The study will run for 52 weeks, inclusive of 26 weeks of TB treatment comprised of 8 weeks of experimental or SOC treatment (based on treatment arm assignment) followed by 18 weeks of SOC treatment with 45 participants in each experimental treatment arm and at least 90 participants in the SOC arm.
NCT04894734
The purpose of this feasibility study is to compare the impact of Spinal cord stimulation \[SCS\] for Spinal Cord Injury (SCI) pain and rehabilitation. SCS, also known as Epidural Electrical Stimulation (EES), will be utilized along with conventional medical management (CMM) or CMM alone. Participation in this research study is expected to last approximately 24 months. All subjects will be evaluated and proceed with implantation of two SCS devices- one tailored based on the individual's SCI for the treatment of neuropathic pain of trunk and limb and a second near the bottom of the spinal cord (conus region) to study the impact on motor, sensory, bowel/bladder outcomes. All patients will also continue receiving CMM, such as medications and physical therapy. Participating subjects will be allocated to one of two treatment groups: 1. Placebo arm: SCS OFF + CMM. Under the direction of the study physician, the patient may receive a variety of treatments, such as medications and various forms of rehabilitation. 2. Treatment arm: SCS ON + CMM. The study treatment Spinal Cord Stimulation \[SCS\]: the study physician will perform a trial procedure to see if the study procedure works for the patient and may implant a permanent device if it is successful. There is a temporary trial procedure, or a "test drive," which usually lasts 5-7 days. If this is successful, patients will discuss a more permanent implant. This study involves the concurrent placement of two SCS devices (one focused on pain and the second for rehabilitation). For three months, treatment group subjects will have the SCS turned on and will have rehabilitation as part of their CMM. Participants in the placebo arm will have their SCS remain off and will undergo CMM with rehabilitation therapy similar to the treatment group. Neither the subjects nor the treatment team will know which patients are in the treatment or placebo arm. At the end of three months, the study group will be revealed and the placebo group subjects will be allowed to crossover and have their SCS turned on. Rehabilitation visits may be remote and the study duration is approximately 24 months. There may be additional blood tests and clinical exams to collect data on the effectiveness of the therapy. Data at follow-up visits will be compared to the subjects' baseline data and that of the control group at the respective visits.
NCT07472348
The objective of this observational study is to determine how frequently isoniazid (INH) causes liver injury (hepatotoxicity) in adults treated for tuberculosis (TB) or latent tuberculosis infection (LTBI) and to understand which factors increase this risk. The study also aims to describe how hepatotoxicity is managed in real-world clinical practice and whether treatments such as corticosteroids can improve liver function tests. The main questions this study aims to answer are: * How frequently does INH-induced hepatotoxicity occur in adults treated for TB or LTBI? * What demographic, clinical, microbiological, or lifestyle factors increase the risk of developing hepatotoxicity? * How do different management strategies, including treatment modification or the use of corticosteroids, affect liver recovery and completion of TB/LTBI therapy? This study does not involve experimental treatments. Researchers will analyze information already collected during routine clinical care, both retrospectively (from 2020 to 2025) and prospectively (2026-2028). There is no comparison group, but participants may have different clinical profiles or treatments, which will be compared to understand risk factors and outcomes. Participants will: * Receive standard treatment for tuberculosis or LTBI, including isoniazid, as prescribed by their treating physicians. * Undergo routine assessments, such as blood tests, microbiology, imaging, and clinic visits, as part of their regular care. * Their clinical data will be recorded in the study database to analyze liver function trends, treatment changes, and outcomes. The study will contribute to improving understanding of INH-induced hepatotoxicity and supporting safer and more effective treatment strategies for tuberculosis and LTBI.
NCT07469020
The goal of this interventional study is to evaluate the rate of existing lower limb peripheral artery disease (PAD) in patients with surgically lumbar spinal stenosis (LSS). PAD and LSS can present similar symptoms and it can be difficult to diagnose PAD using conventional methods, depending on the location of the arterial disease. The main questions it aims to answer are : * What's the prevalence of PAD in LSS patients? * Which exam among routine tools is the most accurate to diagnose PAD in this population? Around their surgery for LSS (a few weeks before or after), participants will be included in a vascular medicine service. After checking of eligibility criteria, they will undergo a contrast-enhanced CT scan for the diagnosis of PAD and various routine diagnostic tests: Doppler ultrasound, treadmill tests, pressure index, pulse palpation.
