NCT06282718
Acute respiratory infection (ARI) is the commonest reason for consulting in community care. Furthermore, new and re-emerging pathogens are often first noticed in primary care (PC). The POS-ARI-PC study is a long-term study, with the aim of describing the nature of ARI in adults and children presenting to PC across Europe. The POS-ARI-PC study will provide critically important data on the presentation and management of ARI, and build a research-ready infrastructure for studies related to the treatment, diagnosis, and prevention of ARI in primary care settings. Additional observational studies will be embedded and use the infrastructure developed in POS-ARI-PC.
NCT07159230
This study aims to evaluate the clinical value of point-of-care multiplex PCR testing (POCT) in guiding early diagnosis and target treatment for acute respiratory infections in primary healthcare settings.
NCT05814237
Acute respiratory infections (ARI) are one of the most frequent reasons for hospital admission and antibiotic use, and can be caused by a broad range of pathogens, including respiratory viruses with proven epidemic potential, e.g. influenza and coronaviruses. The POS-ARI-ER study will focus on describing the different routine diagnostic and therapeutic practices in the work-up and treatment of ARI, as well as clinical outcomes across the patient population. In addition, POS-ARI-ER aims to characterise both the adult patient population with ARI presenting to acute hospital settings in Europe, and the aetiology of ARI in these patients.

Antibiotic resistance is an increasingly serious problem in Switzerland which is associated with the exposure and overall uptake of antibiotics in a population. Reduced antibiotic prescribing for outpatients is paralleled by a decrease in antibiotic resistance rates. In a recent pragmatic trial, the investigators found only promising yet not very conclusive results as those were present only in some groups. This nationwide antibiotic stewardship program with routine feedback on antibiotic prescribing was not associated with an overall change in antibiotic use. In older children, adolescents, and younger adults fewer antibiotics were prescribed, but not consistently over the entire intervention period. Hence, the investigators now aim to evaluate a better-tailored program to obtain a better understanding of the effects on patient-relevant outcomes, antibiotic resistance, and the underlying mechanisms leading to different effects in certain subgroups of patients. The investigators plan to evaluate a nationwide antibiotic stewardship program combining routine prescription feedback with the provision of physician and patient education material for primary care physicians in Switzerland. The project is conducted within the framework of the National Program on antimicrobial resistance by the Swiss National Science Foundation. Also, additional subprojects will be done where we will assess the impact of COVID-19 on AB prescription by comparing the years 2017,2018, and 2019 with the year 2020 data.

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
NCT02046577
The main purpose of this study is to determine whether weekly oral vitamin D supplementation is effective to prevent acute respiratory tract infections in children. The hypothesis of the study is that vitamin D supplementation reduces the incidence and severity of acute respiratory tract infections in children.
NCT00272116
Zinc deficiency is common in developing country children, as food intakes are often low, foods from animal sources are infrequently used, the bioavailability of zinc from staple cereal-based diets is limited and zinc losses occur during recurring diarrheal illnesses. Zinc deficiency is associated with impairment in immunological and other defenses against infection and increased rates of serious infections. Due to limitations in currently used biochemical markers, supplementation trials in populations likely to be deficient provide a reliable means of assessing health consequences of zinc deficiency. A significantly lower incidence and prevalence of diarrhea has been observed in zinc supplemented developing country children in several placebo-controlled trials. The effect of routine zinc supplementation on lower respiratory tract infection is still unclear. We, therefore, evaluated the impact of daily zinc supplementation in a representative sample of children aged 6 to 30 months enrolled from a New Delhi slum area, with a sample size sufficient to determine the impact on the incidence of severe diarrhea and acute lower respiratory infection.
