Risk of SDRs Under 3HP and 1HP Regimen for LTBI
Latent Tuberculosis InfectionSuccessful implement of preventive therapy for subjects with latent tuberculosis infection (LTBI) is the critical step for elimination of tuberculosis (TB). The major obstacle of traditional preventive therapy is the unacceptable long treatment duration, taking isoniazid 5mg/kg daily for a total of 9 months (9H), thus seriously compromising its acceptability. With the introduction of 12-doses weekly high-dose (15 mg/kg) rifapentine plus isoniazid (3HP regimen), the completion rate of 3HP has be shown to be much higher than 9H. However, 4.9% to 9.1% of LTBI cases who received 3HP failed to complete treatment because of side effects. Systemic drug reactions (SDRs), even hypotension and shock, under 3HP treatment are higher than 9H treatment. A recent study in HIV patients demonstrated that a new short-term regimen, consisting of isoniazid 5mg/kg plus rifapentine 10mg/kg daily for one month (1HP), has a similar risk of adverse reactions as 3HP. Clinical study with head-to-head comparison between 3HP and 1HP, however, remains lacking. The prospective multicenter study is conducted to investigate whether risk of SDRs under 1HP is lower than that under 3HP. Hypothesis: 1HP has a lower incidence rate of SDRs than 3HP Objectives: To compare the risk of SDRs in 1HP treatment and in 3HP treatment To explore side effect profile of 1HP Methods: This multicenter randomized control trial will compare the risk of SDRs under conventional 3HP regimen (Arm 1: 3HP), and a new regimen consisting of daily rifapentine (10 mg/kg) plus isoniazid (5 mg/kg) for 1 month (Arm 2: 1HP).

NICU Antibiotics and Outcomes Trial
Microbial ColonizationExtreme Prematurity4 moreThe goal of the NANO trial is to study the longstanding clinical practice of empirically administering intravenous antibiotics to extremely low birthweight (ELBW) infants in the first days of life. In this 802-subject multicenter placebo-controlled randomized clinical trial, the hypothesis to be tested is that the incidence of adverse outcomes is higher in babies receiving empiric antibiotics (EA) in the first week of life compared to babies receiving placebo. The study targets a population of ELBW infants in whom the clinical decision to use or not use EA is currently most challenging -- infants that are clinically stable that did not have a known exposure to intraamniotic infection and were not born preterm for maternal indications. The primary outcome is the composite outcome of late-onset sepsis (LOS), necrotizing enterocolitis (NEC), or death during the index hospitalization. Secondary safety outcomes will include total antibiotic days, days to full enteral feedings, and common morbidities in preterm infants that have previously been linked to EA, e.g. retinopathy of prematurity and bronchopulmonary dysplasia. Weight and length z-score, and head circumference, are standard measures to be collected weekly by clinical team per a standardized protocol.
mNGS -Guided Antimicrobial Treatment in Early Severe Community-Acquired Pneumonia Among Immunocompromised...
Severe Acute Respiratory InfectionCommunity-acquired Pneumonia3 moreSevere Community-acquired pneumonia (SCAP) is a leading global infectious cause of intensive care unit (ICU) admission (approximately 20%-30%), and the primary reason of mortality and morbidity in immunocompromised patients. There is a global increase of patients with distinct immunocompromised conditions due to the advance of cancer treatment, increasing biologics, and immunosuppressants for autoimmune diseases and growing organ transplant recipients, and it has been estimated that patients with immunocompromised conditions account for approximately 35% of all intensive care unit (ICU) admissions. Immunocompromised patients with SCAP have more factors to complicate with sepsis, respiratory failure, acute respiratory distress syndrome, and the mortality rate can be up to 50%. With the aim to apply early accurate antimicrobial therapy to improve clinical prognosis of SCAP patients with immunocompromised conditions, timely identification of pathogen is particularly important. Conventional microbiological diagnostic methods such as standard microbiologic cultures, microscopy, polymerase chain reaction (PCR), respiratory virus multiplex PCR, as well as pathogen-specific antigens and antibody assays, are currently commonly used to detect pathogens, although they have various limitations. However, conventional antimicrobial therapy depends on the results of conventional diagnostic methods, which may delay timely accurate antimicrobial therapy at the initial stage, and the mortality of immunocompromised patients with SCAP may be increased. Metagenomic next-generation sequencing (mNGS), which can determine pathogens more quickly (usually within 24h) and accurately comparing with conventional diagnostic methods by analyzing cell-free nucleic acid fragments of pathogens using appropriate lower respiratory tract (LRT) specimen, is increasingly used in severe respiratory infectious disease, especially among immunocompromised patients. This study aims to determine whether mNGS (using LRT specimen) guided antimicrobial treatment improves clinical prognosis of SCAP patients with immunocompromised conditions when compared with conventional antimicrobial treatment.

Hydrochloric Acid Lock Therapy for Central Line-associated Bloodstream Infections
Central Line-associated Bloodstream Infection (CLABSI)Aim: This study will test whether treatment of central line-associated bloodstream infections (CLABSI) with hydrochloric acid lock therapy (HALT) can significantly reduce the risk of treatment failure (comprising failure to clear initial infection, relapse of infection, or reinfection) in patients treated for cancer or hematologic diseases. Study design: A multicentre, double-blinded, randomized controlled trial. Patient population: Patients (0-100 y) with cancer or a hematologic disorder and a CLABSI treated at Copenhagen University Hospital, Aarhus University Hospital, or Odense University Hospital, Denmark. Randomization: Patients are equally assigned (1:1) to receive either HALT or placebo (normal saline). In addition to the study intervention, patients in both arms will receive standard systemic antibiotic therapy. Sample size: A target population of 250 patients
The Safety, Completion Rate and Prevention Effect by Rifamycin-containing Regimens for Latent Tuberculosis...
PulmonologyTuberculosis (TB) remains the leading infectious disease worldwide and kidney transplant recipients (KTR) is high risk population needing prevention from reactivation, which cause high mortality. In fact, its latent tuberculosis infection (LTBI) is increasing after transplantation and has been identified as a risk factor for TB. However, the suitable regimen for LTBI treatment in KTRs remains unclear. Currently, three-month rifamycin-containing regimens, such as weekly rifapentine and isoniazid (3HP) or daily rifampicin and isoniazid (3HP), are common because its non-inferiority to nine-month of daily isoniazid (9H) and high completion rate by its short course in TB contacts. However, KTRs have many differences from general population, like use of immune-suppressants and possible residual renal insufficiency, so that to prescribe rifamycin-containing LTBI treatment regimens may have many concerns. One biggest concern is that drug-drug interaction between rifamycin and immunosuppressants. In addition, there is no study before in investigating the use of rifamycin-containing regimen in the population of KTRs (only study for kidney transplant candidates).
