A Pilot of Pediatric/Adult Study of Gene Expression Profiling and Clinical Characterization of Phototoxicity

This study will examine the phototoxicity, a reaction to light that is like exaggerated sunburn, which occurs in people who take medications such as voriconazole, a medication used to fight fungus. Sunscreens might protect the skin from the reaction. Although phototoxicity from voriconazole is not completely understood, it may be related to how that medication is metabolized in the liver by enzymes called cytochrome P450 enzymes-and mainly by one known as 2C19. A way to evaluate phototoxicity is through microarrays, which measure how much each gene is expressed in cells from tissues such as skin. Patients ages 8 and older who are scheduled to begin taking or who currently take voriconazole may be eligible for this study. Also, patients ages 18 to 45 in good health who have skin tone known as Type 2, which usually burns and tans only slightly following sun exposure, may be eligible. All patients will visit the Dermatology Clinic. They will complete two questionnaires, on medical history and medications, as well as the skin response to sunlight, and donate about 3 teaspoons of blood. Patients who are scheduled to take voriconazole will visit the clinic four times, that is, two visits 2 consecutive days before beginning the medication and two visits on 2 consecutive days after taking it for at least 7 days. Each visit will take 1 to 2 hours. Patients about to take voriconazole will have a blood test and undergo a physical exam of the skin test site, on the buttocks. Researchers will take photographs of the specific site and do tests to measure skin reaction to ultraviolet (UV) light. UV light will be shined on 15 small areas of the skin, each 1 x 1 centimeters. After 24 hours, any redness that occurs on the skin will be checked. Afterward, patients will begin taking voriconazole according to directions by the researchers. At 10 or more days later, patients will visit the clinic. Sunscreen will be applied and 1 hour later after administration of voriconazole, a blood sample will be drawn to check the level of medication. Then UV light will be shined on 23 areas of skin 1 x 1 centimeters. More photographs will be taken of test sites to record changes in skin redness. On the next day, the skin response will be evaluated. Participants in the control group will be asked to avoid UV radiation by wearing hats and clothing, and using sunscreen. They will be given the doxycycline, an antibiotic, and undergo procedures with UV light shined on small areas of the skin, on the buttocks. Control participants will have 7 study days, with visits lasting from 1 to 3 hours and probably not exceeding 8 hours. They will have two shave biopsies on Study Day 2 and on Study Day 7 to determine how the skin has responded to UV light exposures. ...

Impact of Procalcitonin-guided Algorithm on Early Discontinuation of Antibiotic Therapy

In this randomized controlled open-label trial, conducted in 7 French Pediatric and Neonatal Intensive Care Units (ICUs), investigator team hypothesize that the use of a procalcitonin (PCT)-guided algorithm to discontinue antibiotic treatment will decrease antibiotic duration in critically ill children treated for a suspected or proven bacterial infection. Two hundred and ninety-six eligible patients will be randomly assigned in two groups: either PCT-guided or standard-of-care antibiotic discontinuation, and monitored over 28 days, until the end of their hospitalization, or up to the end of antibiotic treatment for bacterial infection recurrence occurring up to 28 days after the day of randomization.

A Study to Evaluate the Immunogenicity and Safety of 13-valent Pneumococcal Conjugate Vaccine (PCV13i) in Healthy Infants Aged 2 Months (Minimum 6 Weeks)

This is a Phase 3 randomized, observation-blinded, active-controlled, parallel-group clinical trial designed to evaluate the immunogenicity, safety, and functional antibody response of the experimental vaccine versus the control vaccine in healthy Thailand infants vaccinated at a 2+1 schedule (2 months, 4 months and 12-15 months). The trial will enroll approximately 600 healthy infants aged 2 months (at least 6 weeks) who will be randomly assigned in a 1:1 ratio to receive either the experimental or control vaccine, with 100 in each group (200 in total) randomized to subgroups and subject to additional immunogenicity assessments. All participants will be evaluated for solicited adverse events for 7 days and unsolicited adverse events for 30 days post each vaccination. Immunogenicity evaluation will be performed in all participants at baseline and post the booster dose, while the sub-cohort participants will be evaluated for post primary series immunogenicity additionally.

Large Algorithm Setting and Validation Study

In this pilot study, prospectively acquired clinician-collected and participant-collected vaginal swab specimens will be obtained from up to 1000 individuals with signs and symptoms of vaginitis to develop and validate a bacterial vaginosis diagnostic algorithm and evaluate the performance of the Nanopath assay. The Nanopath assay is an amplification-free molecular test that detects pathogens associated with vaginitis. The performance of the Nanopath assay will be assessed by comparing Nanopath assay results to previously FDA-cleared commercial tests and yeast culture.

Personalized Antibiotic Therapy - Point-of-Care Determination of Blood Levels of Beta-Lactam Antibiotics Using Coated-Blade-Spray Ion Mobility Spectrometry

A new analytical method for determining beta-lactam antibiotic concentrations in the blood of intensive care patients is to be evaluated. Patients receive antibiotic therapy with beta-lactam antibiotics in the general surgery intensive care unit. Blood samples are collected daily for routine clinical testing; a portion of these samples is used for the new method. The antibiotic levels, routinely measured using the gold standard, are documented and used as a reference point. The goal of the study is to establish a rapid and cost-effective method for determining beta-lactam antibiotic levels, which will subsequently enable rapid dose adjustment.

Study of the Involvement of IL-17 / IL-22 Pathway in Bacterial Exacerbations of COPD

Chronic obstructive pulmonary disease (COPD) is a worldwide chronic inflammatory disease of the airways linked to environmental exposure. The chronic course of COPD is often interrupted by acute exacerbations which have a major impact on the morbidity and mortality of COPD patients. A bacterial etiology for these exacerbations is common (almost 50%). Moreover, airway bacterial colonization linked to an increased susceptibility is observed in COPD patients. Effective Th17 immune response is needed to develop a good response against bacteria. Thus, this study aims to demonstrate that there is a defective IL-17/ IL-22 response to bacteria in COPD leading to airway bacterial colonization and infection.

Viromes in Infants Presenting With a Septic Syndrome

Fever in infants younger than 3 months is a common reason for emergency department visits and is associated with a significant risk of serious bacterial infections. Because it is difficult to distinguish bacterial from viral infections at presentation, management is often aggressive and includes invasive procedures, hospitalization, and empiric antibiotic therapy. Despite advances in molecular diagnostics, the etiology of fever remains unidentified in a substantial proportion of cases. This study aims to assess the presence of pathogenic viruses in respiratory and intestinal samples from febrile infants younger than 3 months compared with afebrile controls, and to explore associations with clinical, biological, environmental, and socio-economic factors

Diagnostic Application of AI-ROSE in Severe Pneumonia

AI-ROSE is an innovative immunofluorescence staining combined with artificial intelligence image analysis technology that uses a fully automated fluorescence microscope to image pathogens in real time. AI algorithms automatically identify pathogen types (such as bacteria, fungi, etc.) and cellular backgrounds, quickly interpret results, and automatically issue color graphic reports for clinical doctors to take earlier and more accurate targeted treatment for critically ill patients. This study used bronchoalveolar lavage fluid as a biological sample and compared it with traditional examination methods to analyze the diagnostic accuracy and clinical practicality of AI-ROSE in patients with severe pneumonia.
