Active clinical trials for "Respiratory Tract Infections"

The purpose of this study is to determine whether the consumption of a nutritional supplement with micronutrients and herbal extracts has an effect on the incidence of acute respiratory infections in susceptible adults. Our hypothesis is that subjects who consume the nutritional supplement will have a lower incidence and duration of acute respiratory infections in comparison with the placebo group.

The purpose is to determine if the consumption of study product has an effect on acute respiratory infections and/or diarrheal disease.

This is a feasibility double-blind randomised controlled trial in 32 participants. It evaluates the feasibility of a full trial which will examine the efficacy of weekly supplementation of cholecalciferol (vitamin D3) relative to placebo on the subsequent frequency and severity of objectively-verified symptomatic acute respiratory tract infection, overall and as a proportion of detected colonisations of the upper respiratory tract by 9 of the most common aetiologic viral pathogens.

Currently, there is no treatment for children less than one year of age with influenza related lower respiratory tract infection that is either considered standard or registered in any country. This dismal scenario exists even though influenza related LRTI is a significant illness causing morbidity and mortality, especially in children less than 6 months of age. Avian influenza has been reported rarely in children less than one. There are no data in Vietnam and very few data in Thailand on the burden of influenza in children less than one. This young age group suffers high mortality. Oseltamivir may be beneficial in such children. This is basis of this trial.

Background: The medical and economic burden of upper respiratory tract infections (URTIs) is extremely high, while prevention and treatment options are limited. Therefore, there is a constant need for new methods in order to significantly decrease such morbidity. Extensive evidence shows that vitamin D is associated with respiratory health, including in the prevention and treatment of URTIs. Competitive swimmers have a high prevalence of URTIs, and can serve as a model for research in this field. The study hypothesis is that vitamin D supplementation to young swimmers with low vitamin D levels will reduce the frequency, length, and severity of URTIs and their accompanying functional impairment, while improving cellular immune function and physical function. Methods: After screening 100 competitive adolescent swimmers to obtain ~60 with low serum levels of vitamin D, this study group will be randomized to receive either vitamin D supplementation (2000 IU/d) or placebo, given in a double blinded fashion for three months. Participants will fill a daily questionnaire regarding frequency, length and severity of URTIs symptoms and functional impairment. Blood will be drawn to evaluate changes in vitamin D status (25(OH)D) and immune function among study participants at the beginning of the study and after supplementation. Physical function on land and in water will also be assessed. Expected results: Increase in serum 25(OH)D levels following supplementation will significantly decrease the frequency, length and severity of URTI's and their functional impairment, while enhancing the cellular immune system function and physical capacity.

Acute illness is the most common presentation of children attending ambulatory care settings. Serious infections (e.g. meningitis, sepsis, pyelonephritis, pneumonia) are rare, but their impact is quite large (increased morbidity, mortality, induced fear in parents and defensive behaviour in clinicians). Early recognition and adequate referral of serious infections are essential to avoid complications (e.g. hearing loss after bacterial meningitis) and their accompanied mortality. Secondly, we aim to reduce the number of investigations, referrals, treatments and hospitalisations in children who are diagnosed with a non-serious infection. Apart from the cost-effectiveness, this could lead to less traumatic experiences for the child and less fear induction for the concerned parent. Finally, we aim to support the clinicians to rationalise their antibiotic prescribing behaviour, resulting in a reduction of antibiotic resistance in the long run.

This study assesses the seasonal of influenza vaccine effectiveness in adults hospitalised with laboratory-confirmed influenza through a network of hospitals in France. Also, To better understand the burden of other respiratory viruses such as respiratory syncytial virus (RSV) and SARS-CoV-2 in hospitalized adults, we need to describe and quantify the population hospitalized due to theses other respiratory viruses.

The purpose of this study is to conduct a Randomized Control Trial (RCT) in a developing country setting in order to evaluate the role of alcohol based hand sanitizers (ABHS) in preventing the transmission of infectious diseases in areas where water is a scarce resource. The investigators want to find out if the use of ABHS reduces the incidence of two leading causes of morbidity and mortality in children under 5 years of age in the developing world: acute diarrheal disease (ADD) and acute respiratory infections (ARI).

Diarrheal diseases are a major cause of morbidity and mortality globally in children less than 5 years of age. Prolonged diarrhea, recurrent infections and growth failure in developing countries are usually a consequence of micronutrient deficiencies including zinc. The primary aims of the proposed study are to evaluate the effect of the use of multiple micronutrient sprinkles including zinc on compliance of supplement use and the incidence of recurrent diarrheal and respiratory illnesses. The proposed study will be conducted at the Fima Lifshitz Metabolic Research Center, Department of Pediatrics, Universidade Federal Da Bahia, Salvador-Bahia, Brazil over a period of 18 months. This is a double-blind placebo-controlled trial involving the use of 2 types of micronutrient sprinkles in a group of 120 children who attend a day care center in Salvador, Bahia. They will be randomized into 2 groups of 60 children each. The intervention group will receive sprinkles containing zinc while the control group will receive micronutrient sprinkles without zinc. The primary outcome variables of interest are zinc status, stool zinc losses and diarrhea duration. Both groups of infants will be monitored at monthly intervals for an initial duration of 180 days for zinc status, diarrhea episodes, respiratory illness and growth. This study will allow for the establishment of a cohort of children who will be monitored in a micronutrient supplementation trial using sprinkles.
