Filter by:The goal of this clinical trial is to compare the standard triple therapy with Bismuth quadruple therapy in children infected with Helicobacter pylori. The main questions to answer are: - the safety - the efficacy of the quadruple protocol with Bismuth subcitrate Participants will be randomised in 7-days eradication therapy group and 14-days eradication control group.
pleural infection remains a common medical problem with significant mortality and morbidity despite a better undrstanding of the aetiology , pathophysiology and recent advances in management approaches . the cornerstones of the managment op pleural infection include early identification of cases and accurate diagnosis . suitable antibiotic therapy , nutrition managment , efficient drainage of infected collection via chest tube with or without adjunctive therapies including intrapleural agents and ultimately surgical managment .
Malaria is a major public health problem. There were around 240 million cases of malaria and 627,000 deaths worldwide in 2020. Most of the deaths are in children under five living in Africa. It is a major problem for those who live in affected areas and for travellers. There is a great need for a safe, effective malaria vaccine. This study is being done to evaluate an experimental malaria vaccine for its safety and also look at the body's immune response to the vaccine. The vaccine tested in this study is called and "RH5.1". This is given with an adjuvant called "Matrix-M". This is a substance to improve the body's response to a vaccination. The aim is to use the vaccines and adjuvant to help the body make an immune response against parts of the malaria parasite. This study will assess: 1. The safety of the vaccines in healthy participants. 2. The response of the human immune system to the vaccines. This will be achieved by giving participants three doses of the RH5.1 vaccines at two different dose levels (10 micrograms and 50 micrograms). One group will have 3 doses of 10 micrograms given at 0, 1 and 6 months whilst the other will receive 2 doses of 50 micrograms (at 1 and 2 months) followed by a 10 microgram dose at 6 months- known as a 'delayed fractional dose'. Blood tests and information about any symptoms will be performed/collected that occur after vaccination. Information from previous studies suggests that a delayed fractional dose improves the immune response to the vaccine, particularly in terms of the antibody response. Current prediction is that this improvement is due to the delay in dosing, rather than the reduction in dose, and this study will help to answer that. Having a vaccine at a single dose is important for efficient production and dosing for vaccines rolled out in national programs so being able to move away from 'delayed fractional dose' regimens to 'delayed final dose' regimens will be important for vaccine development.
Bronchiolitis obliterans (BO) is an irreversible chronic obstructive pulmonary pathology leading to obstruction and/or obliteration of the small airways. In children, the most common form of BO occurs following a serious lower respiratory tract infection. This is a rare complication; the incidence is unknown. The diagnosis, often late, is made on clinical, spirometric and radiological arguments. The pathophysiology would be linked to damage to the airway epithelium. PIBO is most commonly associated with adenovirus (ADV) infection (serotypes 3, 7, 11 and 21) but also other viruses such as rhinovirus (RV). The treatment of PIBO is not clearly established, it remains empirical. The research hypothesis is that the morphology of the nasal epithelium of children with ADV or RV infection is different for those progressing to PIBO. The main objective of the proposed observational study is to characterize damage to the respiratory epithelium in these children. This is a single-center prospective longitudinal study (AP-HM), in children aged 1 month to 6 years, comparing children hospitalized for lower respiratory infection by ADV or RV progressing or not to PIBO. All children included will have a nasal swab and brushing on D0. Children developing PIBO will have nasal brushing with bronchial endoscopy with bronchial biopsies and bronchoalveolar washing at the time of PIBO diagnosis and again at M6 in case of partial response to treatment. This is therefore a pilot study aimed at defining damage to the respiratory epithelium in children with PIBO following an ADV or RV infection and the role of respiratory epithelial cells in PIBO.
Mongolia is a traditionally nomadic and population is scarce in rural areas. Thus, the medical care service is not sufficient. In 2000, Mongolian government has developed and implemented the millennium project in cooperation with WHO. During the years pap smear analysis of implemented in all rural areas and clinicians, lab technicians have been taught for the cervical cancer screening. However, the project has finished in 2015 and the rural and district hospitals has lost the trained professionals. Still the cervical cancer is in second place after liver cancer in women. The purpose of the study is to identify the type of HPV genotype and to treat the HPV infection by local interferon α2b. Materials and methods: HPV positive patients will be enrolled to the study. HPV genotype will be determined by the PCR in laboratory. Pap smear will be taken and staged by the CIN. Pathological tissue will be taken under colposcopy with acetic acid test. Follow up visit will be done on 10th, 30th days of the treatment. At the end of 90th days of treatment, pap and histology test will be repeated and CIN regression or viral eradication will be evaluated.
In this clinical trial, the growth (weight for age), product tolerance (product intake, comfort) and infection-related symptoms of healthy infants consuming an IF and FOF containing bio-active ingredients will be evaluated and compared to a group of infants consuming a standard IF and FOF
This is a multi-center, single arm, open-label, phase I study to determine the safety and effectiveness of EBV-TCR-T cell immunotherapy in treating EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) or EBV infection
Arginine is an adjunct to oral health care that has the potential to modulate the composition and activity of the microbial community of dental biofilms towards a health-related status without harmful effects for the resident oral microbiota. The aim of the study is to investigate the effects of arginine treatment compared to placebo on the composition, metabolism, and microarchitecture of biofilms grown in situ in the oral cavity of caries-active participants.
This study aims to collect clinical cases and follow-up data from patients with chronic pulmonary aspergillosis, post-COVID-19 aspergillosis, and post-COVID-19 patients without aspergillosis. Using in vitro assays, we will measure the phagocytic function of neutrophils when stimulated by fungal hyphae, their ability to produce neutrophil extracellular traps (NETs), the expression of cell surface molecules at the time of enrollment, changes in cell surface molecule expression after stimulation with fungal hyphae, and the quantification of autoantibodies in the blood. This research will focus on the short-term (within 3 months), medium-term (6-12 months), and long-term (more than 12 months) changes in cell surface molecules and functions following infection.
Osteoarthritis (OA) is the most common cause of disability in older adults worldwide affecting 7% of the global population, or more than 500 million people globally. Total joint replacements (TJR) can help bring relief to those with osteoarthritis when other treatment options are no longer helpful. Infection is the main reason hip and knee replacements "fail". Failure leads to repeat surgeries that are often more complicated and less likely to be successful than the first surgery. Reducing the risk of infection is extremely important, antiseptic washes and antibiotics may help us do that. After joint replacement surgery, orthopaedic surgeons wash and clean the surgical wound to lower the risk of infection. The goal of this clinical trial is to determine if the use of antiseptic solutions to wash the surgical site and placing an antibiotic directly into the wound will reduce the number of infections requiring reoperation. Patients having total joint replacements will be randomized (like flipping a coin) to receive 6 possible combinations of washes and / or antibiotics. Participants will be followed for one year after TJR to compare the rate of infection in each group.
