Active clinical trials for "Respiratory Tract Infections"

Antibiotic resistance is a worldwide health care problem. Increasing use of antibiotics is associated with an increase in the prevalence of bacteria resistant to the antibiotic used. Reducing antibiotic use can be effected by improving antibiotic prescribing quality in two complementary ways. One is to limit antibiotic prescribing to those patients who will benefit from the treatment and two is to prescribe these patients the recommended antibiotic. International research has shown that a web-based communication training for the prescriber combined with an interactive booklet containing relevant patient information (Genomics to combat Resistance against Antibiotics for Community acquired LRTI in Europe INternet Training for Reducing antibiOtic use (GRACE INTRO)) can significantly and safely reduce antibiotic prescribing in adults presenting to primary care with acute cough/lower respiratory tract infections (LRTI). Quality assessment of antibiotic prescribing for respiratory infections in general practice has revealed the use of far too many (broad-spectrum) antibiotics in Belgium. In the proposed project, the investigators aspire to make Belgium the first European country to implement the most cost-effective part of the GRACE INTRO intervention (Translational Research on Antimicrobial resistance and Community-acquired infections in Europe (TRACE) e-learning, www.acutecough.org) at national level and to perform a scientifically sound assessment of the nationwide implementation on outpatient antibiotic use and societal cost.

Clinical research question: Can OM-85 reduce the recurrence of respiratory tract infections (RTIs) in children with AH by stimulating the immunological response of the host and therefore, as a consequence reduce the size of adenoid tissue in children with adenoid hypertrophy? Can this prevent further complications such as surgery need? Half of participants will receive OM-85, while other half will receive a placebo.

In Ethiopia, great majorities (95%) of households rely on solid biomass fuels such as wood, muck, crop residues, and charcoal burned in highly polluting stoves to meet the basic household energy needs with its severe health consequences due to emission of toxic indoor air pollutants. Correspondingly, household air pollution (HAP) from biomass fuel use is now estimated to be responsible for nearly 3.5 million premature deaths annually, with the highest disease burdens experienced by countries in sub-Saharan Africa. HAP ranks as the highest environmental risk factors to premature deaths globally and 2nd leading risk factor next to childhood underweight in most of sub-Saharan Africa countries as well as 3rd leading risk factor of disease next to childhood underweight, and suboptimal breastfeeding in Ethiopia. Usually prevention efforts aimed at reducing HAP and related health burdens have been focused on the use of energy efficient cookstoves. There is, however, rigorous lack of evidence in Ethiopia or in other similar settings whether it is possible to achieve adequate HAP reduction and improve health with locally made energy efficient baking stoves from a public health point of view. Particularly, the popular Ethiopian energy efficient "Injera" baking stove has not been researched through stove trial inquiry. Therefore, research studies are required in Ethiopia on health benefits achieved when households adopt energy efficient baking stoves. In view of that, cluster randomized controlled trial will be employed with experimental study design for one year to test the effectiveness of the Ethiopian improved "Injera" baking stove intervention on reducing HAP and childhood acute respiratory infection (ARI) through comparing equal size groups of children before and after part of households received an improved "Injera" baking stove. Accordingly, the proposed stove trial aims to address an important research gap by determining whether the Ethiopian improved "Injera" baking biomass stove intervention can adequately reduce HAP exposure to prevent childhood acute respiratory infection. With this objective, the proposed stove trial will test the hypothesis that there is a statistically significant difference in HAP levels and incidence of childhood ARI when using traditional versus improved "Injera" baking stove in Northwest Ethiopia

Interferon gamma is a powerful endogenous regulatory cytokine that activates the antiviral immune response, while it also has its own antiviral activity. The objective of this study was to evaluate the effectiveness of the proposed treatment regimen with Ingaron (INN: recombinant interferon gamma human, lyophilisate for preparing a solution for intramuscular and subcutaneous administration of 500,000 IU) in patients with viral pneumonia.

COVID-19 cases are rising substantially in Jordan. Since this is a novel virus, there is still much to be investigated surrounding its pathophysiology in order to attempt to find suitable treatments or better decision-making in the prognosis of the disease. This project aims to identify if soluble angiotensin-converting enzyme (ACE2) can be used as a prognostic factor for COVID-19 severity, which will allow clinicians to manage COVID-19 cases more efficiently. ACE2 is of interest since the coronavirus enters host cells through ACE2 receptors. It can slo be hypothesized that the irus may also bind to soluble ACE2, but without mediating its effects. It si, therefore, expected that those with higher levels of ACE2 would more likely have milder disease. This can potentially help improve survival rate, allowing clinicians to identify the higher-risk patients and monitoring them more closely.

This is an open-label, randomized, single-center, 2-period, 2-sequence, single-dose crossover design study in adult male and female healthy participants. Eligible participants will receive either treatment A (reference): Fluimucil® Acetylcysteine 2% oral solution, 200 mg N- acetylcysteine (NAC) in 10 mL dose, or treatment B (test): Acetylcysteine 2% oral solution, 200 mg NAC in 10 mL dose. Blood sampling will be collected pre-dose and up to 48 hours in each period. After completion of the second study period (i.e. last pharmacokinetic (PK) sample on Day 3 of Period 2) participants will be discharged from the clinic.

The purpose of this study is to identify and characterise bacteria present in the lower airways of children with suspected chronic LRTIs and for whom bronchoalveolar lavage (BAL) is indicated by the clinician.

The objective of this study was to confirm if two formulations of cephalexin tablets are bioequivalent. Test product was Ceporex® (1 g Cephalexin; GlaxoSmithKline) and reference product Keflex® (1 g Cephalexin; Eli Lilly). The single dosage was one tablet. The study was prospective, open-label, randomized, crossover, single dose, with 02 treatments, 02 sequences and 02 periods, under fasting conditions. The population was composed of 26 healthy volunteers, both genders, adults between 18-40 years. The comparative bioavailability of the two formulations was evaluated based in statistical comparisons of relevant pharmacokinetic parameters, obtained from data of drug concentrations in blood.

GSK is conducting a global retrospective chart review of patients treated with zanamivir as part of the Compassionate Use Program (CUP), in an effort to collect as much information as possible on the use of this investigational drug. The retrospective chart review is intended to gain a better understanding of the safety profile of investigational zanamivir and of clinical outcomes in the large number of patients treated outside of a clinical trial setting.

Chronic exposure to (cigarette smoke) CS causes biological changes, including airway remodeling and changes in baseline gene expression profiles at the level of the epithelium. Our own data indicate that chronic exposure to CS suppresses the ability of epithelial cells to enhance antiviral gene expression in response to influenza infection and activate host defense responses. While there is a large body of evidence supporting the notion that exposure to CS causes significant changes in host defense responses, which may be linked to permanent changes in epithelial cells at the genomic level, it is not known whether new and emerging tobacco products have similar or distinct effects. Using live attenuated influenza virus (LAIV) inoculation in human volunteers, this study will compare influenza-induced responses in non-smokers (NS), cigarette smokers (CS), e-cigarette smokers (EC), hookah smokers (HS), and Little Cigar smokers (LCS) in vivo. This will be done by analyzing nasal viral titers, antiviral defense responses, inflammatory mediator production, and markers of immune responses for LAIV-induced responses between the different groups of volunteers.
