Active clinical trials for "Communicable Diseases"

Spinal cord stimulation (SCS) is a medical device inserted beside the spine to treat nerve pain. When the device becomes infected (which happens 4 % of the time) it needs to be taken out and put back in again at a later date. So far we are unsure of how much this process costs. I am going to analyse data collected on a database of all devices taken out due to infection and calculate an average cost of taking them out, the intermediate care and putting them back in again in our hospital only. This will enable us to understand how much this process costs and if there are any methods of reducing the chance of infection in the future; we will be able to work out how much the NHS should pay for these products based on this data. This will be done in Guys and St Thomas's from a database in the chronic pain research department in patients who had their device taken out due to infection. It will take 6 months and will all be retrospective. Additional details may be collected from patients electronic records where needed. These will be collected by a member of the direct care team and pseudonymised prior to adding to the research data set.

Chronic hepatitis C is a long-lasting infectious disease caused by hepatitis C virus (HCV). According to statistics by the World Health Organization (WHO), the global HCV prevalence is estimated at 2.8%, equating to approximately 185 million. Chronic HCV infection can lead to chronic inflammatory necrosis and fibrosis in the liver, and in some patients can develop into hepatic cirrhosis and even hepatocellular carcinoma (HCC), endangering the health and life of patients. The development of direct-acting antiviral agents (DAAs) since 2011 markedly improved antiviral efficacy and significantly shortened treatment cycle, making the drugs convenient for clinical use. Small molecule DAAs exert target-specific effects on proteins involved in the HCV life cycle and have been included in the treatment guidelines by leading associations for the study of liver diseases worldwide. Treatment regimen for hepatitis C - coblopasvir hydrochloride capsules combined with sofosbuvir tablets: Coblopasvir hydrochloride capsule is an NS5A inhibitor that inhibits the replication and assembly of HCV, and sofosbuvir tablet is a NS5B polymerase inhibitor. The primary efficacy results (sustained virologic response 12 weeks post-treatment, SVR12) were comparable between the phase II and III clinical studies: the overall SVR12 in subjects was 97%. The SVR12 after coblopasvir hydrochloride capsules combined with sofosbuvir tablets in genotype 3 infection with cirrhosis and genotype 3b infection with cirrhosis were superior to the results of sofosbuvir and velpatasvir tablets obtained in clinical studies in Asia (83% vs. 72%; 67% vs. 50%). Coblopasvir hydrochloride capsule and sofosbuvir tablet were approved for marketing by National Medical Products Administration of China in Feb. 2020 and Mar. 2020, respectively. This study is designed to evaluate the safety and efficacy of coblopasvir hydrochloride capsules combined with sofosbuvir tablets in clinical practice after marketing.

People of all ages are affected by intestinal parasitic infections(IPIs) ; however, children are the most commonly affected, which is linked to their poor hygienic practices, and weak immune status. In children, IPIs are associated with malabsorption, weight loss, anemia, poor growth rate, learning difficulties, mental retardation and intellectual problems . The difficulty of diagnosis is the main problem in the control of intestinal parasitic infections. The choice of a particular technique is usually influenced by affordability, simplicity, cost, sensitivity in addition to the level of technical skills involved. Microscopic examination remains the cornerstone of parasitological diagnosis which is time consuming and requires an experienced observer to identify the organism. Formalin-ether sedimentation technique is commonly used in laboratories owing to its ability to isolate a large variety of parasites. However, it's a labor intensive procedure and is usually associated with hazards of using the inflammable lipid solvents. The drawbacks of the previous techniques have encouraged the development of commercial products such as Feconomics which is a new ready to use kit for concentration of stool samples in parasitological diagnosis. The aim of the study is : evaluation of the efficacy of Feconomics technique in comparison to traditional techniques i.e., direct smear and formalin ethyl acetate sedimentation technique for the diagnosis of intestinal parasites in school children.

The goal of this observational study is to estimate the prevalence of HPV infections anal and ENT level and according to HIV status in transgender (TG) population. The main question it aims to answer is: What is the prevalence of HPV lesions in transgender population (TG); What kind of high risk HPV (hrHPV) and low risk HPV (lrHPV) are detected at the genital, anal and ENT level

The neurogenic bladder and bowel are two pathological conditions occurring when damaged innervation results in functional alteration of both the bladder and the bowel with a clinical presentation that can vary from retention to incontinence often associated with an increased risk of infection. Specific microbiological patterns of urinary microbiota are associated with states of well-being of the host and play protective and preventive functions for numerous urological pathologies such as urinary tract infections, urinary incontinence and bladder tumors. What the "healthy" profile of the bladder microbiota is in subjects with neurogenic bladder appears currently poorly reported in literature data. Indeed, in these populations different strains of uropathogenic microorganisms, such as E.Coli, Klebsiella, Pseudomonas and Enterococcus, are dominant compared to healthy subjects where Lactobacillus predominates. The characterization of the gut microbiota in terms of composition can be a key tool for understanding the effects that preventive therapeutic and nutritional approaches or clinical procedures have on it, subsequently offering the possibility of improving and complementing these treatments. Among human microbiota, the vaginal one, the "vaginoma", is among the most studied for its correlation with female health status. The "core" of the vaginal microbiome is Lactobacillus which under physiological conditions is represented in particular by Lactobacillus Crispatus, Lactobacillus Iners, Lactobacillus Jensenii and Lactobacillus Gasseri. Immune cells and related PRRs receptors interact with the microorganisms in the vaginal environment of the vaginal environment are the immune cells and the related PRRs receptors thus the close relationship between microbiome and immunity as well as between vaginoma and genitourinary well-being is now evident. The characterization of the gut, urinary and vaginal microbiota in patients with neurogenic bladder secondary to spina bifida and multiple sclerosis can help identify a "health promoting" profile to personalize and characterize the therapeutic approach.

Phase 1, open-label, dose-escalation study to evaluate the safety, tolerability, and immunogenicity of RVM-V001 administered as a single intramuscular injection in healthy adults. Three dose levels will be evaluated, with progression from low- to high-dose level based on the assessment of safety and tolerability. The study will be conducted at one or more sites in Australia.

Rationals: Infection with the Respiratory Syncytial Virus (RSV) is one of the most common causes of respiratory tract diseases. However, treatment for pediatric RSV infection remains supportive to prevent co-infection bacteria and respiratory failure. In recent years, preventive and supportive probiotic therapies for respiratory tract infections (RTIs) have been increasingly strengthened, however, the use of oral administrative probiotics as functional foods is effective only for mild symptoms and not applicable for Acute RTIs (ARTIs). Here, we propose that direct spraying of probiotics into the nose can be a fast and effective symptomatic treatment for ARTIs. Objectives: Investigate symptomatic treatment effects of probiotic product LiveSpo Navax, as liquid-suspension form containing Bacillus spores of safe B. subtilis ANA4 and B. clausii ANA39 strains, in children having acute respiratory diseases caused by RSV: Primary Objective: Evaluation of improved efficacy and reduced treatment time of LiveSpo Navax in children infected with RSV. Secondary Objectives: Measurement of changes in RSV viral load, co-infectious bacterial concentrations, and major cytokine indicators in the nasopharyngeal mucosa before and after 3 days using LiveSpo Navax. Endpoints: Primary endpoint: LiveSpo Navax alleviates RSV-infection symptoms about 25% more effectively, as indicated by 90% of patients using LiveSpo Navax (Navax group) are symptom-free at day 3-6 of intervention depending on symptoms, compared to 65% of patients in Control group. Secondary endpoint: Patients in Navax group had more significant reductions in RSV load (>10 fold) than patients in Control group at day 3 of intervention. Study Population: Sample size is 100. Description of Sites: The study is carried out at Vietnam National Children's Hospital. Description of Study Intervention: Totally 100 eligible patients are divided randomly into 2 groups (n = 50/group each): Patients in Control group received the routine treatment and three times per day 0.9% NaCl physiological saline while the and patients in Navax group received three times per day LiveSpo Navax in addition to the same standard of care treatment. The standard treatment regimen is 3-6 days but can be extended further depending on the severity of the patients' respiratory failure. Study Duration: 12 months

This study will compare the effects of AXA1125, an orally active mixture of amino acids, compared to placebo, on improving muscle function (metabolism) following moderate exercise in subjects with fatigue-Predominant Post-Acute Sequelae of SARS-CoV-2 as well as the safety and tolerability of AXA1125. Subjects will take one dose of AXA1125 or a placebo twice daily for 28 days.

The main goal of this study is to characterize the adaptive immune responses to SARS-CoV-2 infection in a cohort of children with cancer and impaired immune responsiveness and prolonged viral shedding of SARS-CoV-2, and to identify SARS-CoV-2 variants that might arise during poorly controlled virus replication

Primary objective: To compare telmisartan therapy + antiretroviral therapy (ART) versus ART alone during acute Human Immunodeficiency Virus (HIV)a infection in reducing systemic immune activation and trafficking of activated and HIV-infected cells to the central nervous system (CNS), and limiting establishment and persistence of the CNS reservoir of HIV. At 48 weeks (during the telmisartan therapy) and 72 weeks (~6 months after cessation of telmisartan augmentation), the investigator expect subjects in the telmisartan group will have reduced levels of blood and CSF immune activation markers, reduced brain inflammation, lower CSF HIV ribonecleic acid (RNA) and improved neuropsychological testing performance. Secondary objective: In subjects who are willing to undergo the optional inguinal lymph node biopsy, the study will determine whether subjects receiving telmisartan plus ART for 48 weeks develop less lymphoid tissue fibrosis than subjects receiving ART alone for 48 weeks. Subject population: Male and female subjects age ≥ 18 years old with acute HIV infection who are identified and enrolled in SEARCH 010/RV254 protocol will be asked to co-enroll in this study. Number of subjects: 21 Duration of follow-up: 72 weeks Study design: 21 acutely HIV-infected subjects will be randomized 2:1 to treatment with telmisartan + ART (n=14) vs. ART alone (n=7) for the first 48 weeks followed by ART alone in both arms to week 72. Blood and CSF, magnetic resonance imaging (MRI), and neuropsychological testing and exam will be collected at baseline, week 48 and week 72. Inguinal lymph node biopsy is an optional procedure that will be offered at baseline and week 48.
