Active clinical trials for "Infections"

The Coronavirus 2019 (COVID-19) pandemic has resulted in at least four million infections in Norway. The vast majority of cases are diagnosed and followed up in the community, but some with extensive symptoms and large degree of reduced function are referred to regional Covid-clinics. In total this patient group is placing an enormous burden on the already over stretched health care services. As the pandemic subsides the emerging threat of long-term disability from COVID remains to be quantified. Brain fog and cognitive symptoms are common in long COVID in 30% of mild infections resulting in sick leave and loss of daily function, with women overrepresented among long COVID sufferers. The true prevalence and underlying mechanisms of long COVID remains to be quantified. Although vaccination prevents severe infection and death, we have little knowledge on how best to rehabilitate those who suffers from long COVID. Here we propose to develop knowledge on treatment interventions to counteract disability from long COVID and lessening the burden on health care services. We will conduct a study of where we compare a short group intervention with systematic personalised neurocognitive rehabilitation to document symptom alleviation. Our overarching goal is to develop effective programmes for this evolving disease to reduce the suffering for the patients, and thereby reducing costs for health services and society at large.

To evaluate the safety and tolerability of partial HLA-matched VSTs against both CMV and EBV viruses in recipients of allogeneic hematopoietic stem cells with refractory viral infections (CMV and/or EBV). Preliminary evaluation of the efficacy of partial HLA-matched VSTs against both CMV and EBV viruses in recipients of allogeneic hematopoietic stem cells with refractory viral infections (CMV and/or EBV); To monitor the duration and expansion of multi-virus VSTs cells after infusion.

The aim of the study is to investigate the safety and immunogenicity of the RSV/Flu-01E vaccine for the prevention of respiratory syncytial virus infection in volunteers aged18 to 59 years and over 60 years.

Rationale: Respiratory tract infections (RTI) are a major cause of morbidity in young children in high- income countries and the major cause of mortality in developing countries. Causative bacteria and viruses are regular residents of the nasopharynx of asymptomatic individuals (colonization) and live there together with other presumed harmless commensals, without causing disease. These non-pathological infections/colonization episodes are important for transmission, intermediate step to disease and boost immune responses. The investigators recently validated the use of minimally-invasive nasal sampling methods that can be done at home for the study of host and microbial parameters in adults and children. In this study the investigators will focus on the daily microbial and immunological composition of the nasopharynx during health in relation to symptoms. Primary objective: Associate acquisition of pneumococcal colonisation with levels of pre-existing polysaccharide specific memory B cells. Secondary objectives include: Validate the use of synthetic absorptive matrices (SAM) for detection of respiratory pathogens versus nasopharyngeal swabs (NPS) and saliva; Assess dynamics of URT infection/colonisation and examine its relationship with symptoms, host responses and microbiota; Measure transmission between children and parents and immune responses in parents. Study design: Prospective community-based cohort study.total of 45 children, aged 1-5 years old attending daycare or (pre-)school, will be included, including a pilot of 10 children to assess tolerability. If there are insufficient pneumococcal acquisitions in the study to assess the primary outcome, additional children can be recruited in groups of 3 or 4 children (up to 10). For a subset of participating children, both parents will be asked to self-collect daily saliva during the study. Primary study parameters: Frequency of systemic polysaccharide specific B cells in children that become colonised during the study versus children that do not become colonised Secondary study parameters: Dynamics of respiratory bacteria and viruses during URT infection/colonisation. Presence and load for bacteria and viruses in children in SAM versus saliva and NPS. Local microbiota and immune profiles and association with infection/colonisation and symptomology. For a subset of parents, daily presence and load of bacteria and viruses as well as host immune factors measured in saliva.

Colistin can be used to treat the infection caused by carbapenem-resistant enterobacteriaceae(CRE). In China, patients diagnosed with Hospital-acquired-pneumonia (HAP)or bloodstream infection caused by CRE are recruited, and randomly assigned to two groups, and in one group the patients accept treatment with colistin, however in another group, the patients accept treatment without colistin. The efficacy and safety of the treatment between the two groups are compared.

The purpose of this study is to evaluate the efficacy and safety of delpazolid add-on therapy in Patients with Refractory Mycobacterium abscessus Complex Pulmonary disease

The goal of this clinical trial is to evaluate the effectiveness of sofosbuvir/daclatasvir combination for children aged ≥ 6 years old and adolescents with active HCV infection in Cambodia

The purpose of this study is to demonstrate the efficacy of Bacille Calmette Guerin (BCG) revaccination against sustained Mycobacterium tuberculosis infection versus placebo in previously BCG vaccinated QuantiFERON®-TB Gold Plus Assay (QFT) negative, healthy adolescents.

Determine the optimal therapeutic combination associated with complete clinical and anatomical remission of anal suppurations of Crohn's disease at 12 months.

Infectious diseases remain leading causes of mortality and morbidity in children. Rapid and accurate diagnosis of infectious diseases in children is important for developing an effective treatment and management strategy. However, the current diagnosis of infectious agents mainly depends on culture and molecular testing. Both of the methods either has long turnaround times or narrow detection range. Metagenome next generation sequencing (mNGS) has been applied to the diagnosis of central nervous system infection, lower respiratory tract infection and sepsis, which showed high positive rate, short turnaround time. However, there is currently no assessment of the diagnostic efficacy of mNGS in children infectious diseases. This study used the DNA extraction and library construction technology developed for children's low volume clinical samples to assess the sensitivity and specificity of mNGS in the diagnosis of infectious diseases, and the treatment outcome based on mNGS test results.
