Filter by:The Purpose of this study is to evaluate the efficacy and safety of intravenous HRS -8427 in patients with complicated urinary tract infection, including acute pyelonephritis.
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
The purpose of this study is to evaluate the skin quality improvement and colonization efficacy following the application of probiotic Micrococcus luteus Q24 (BLIS Q24) to the face from a serum format in healthy adults.
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 is designed to evaluate the clinical and antibacterial efficacy, safety and pharmacokinetics of the drug Fluorothiazinone compared to placebo to prevent nosocomial gram-negative bacterial infections with participation of patients on mechanical ventilation. The main objectives of this study are: - Evaluation of the clinical and antibacterial efficacy of the drug Fluorothiazinone in combination with standard measures for the prevention of nosocomial infections compared to placebo in combination with standard measures for the prevention of nosocomial infections for the prevention of nosocomial infections caused by bacterial gram-negative flora in patients on mechanical ventilation. - Evaluation of the safety and tolerability of the drug Fluorothiazinone in patients on mechanical ventilation. - Evaluation of the pharmacokinetics (in whole blood) of the drug Fluorothiazinone with a single daily dose of 2400 mg/day. Researchers will compare results for the treatment and the placebo arms.
