Active clinical trials for "Bronchopulmonary Dysplasia"

The aim of the TINN2 study is to evaluate the efficacy of azithromycin in prevention of bronchopulmonary dysplasia in preterm neonates.

This study is an open-label, single-center, dose escalation study to evaluate of safety and efficacy of human umbilical cord -derived mesenchymal stem cells (hUC-MSCs) in children with moderate and severe bronchopulmonary dysplasia.

The purpose of this study is to evaluate long-term safety and efficacy outcomes following previously administered short-term exposure to SHP607, as compared to a standard neonatal care group.

Spontaneous breathing supported by nasal continuous positive airway pressure (nCPAP) is thought to have some advantages compared with mechanical ventilation in premature infants. In addition, early surfactant administration has been shown to be superior to delayed use. The aim of this pilot study was to describe the feasibility of TAKE CARE (early administration of surfactant in spontaneous breathing) procedure and compare its short-term and long-term results with InSurE procedure.

This is a follow-up study to investigate the long-term safety and efficacy of human umbilical cord -derived mesenchymal stem cells (hUC-MSCs), for the treatment of BPD in premature infants. Subjects who participated in and completed the initial stage of the PhaseⅠtrial (NCT03558334 ) will be followed-up until 48 months after the hUC-MSCs transplantation.

Premature birth is a major cause of neonatal death in addition to neonatal asphyxia and infections. Early in life, premature babies must get aggressive nutrition so that there is no extrauterine growth restriction (EUGR) in the Intrauterine Growth Restriction (IUGR) group compared to the non-IUGR group. Other factors that also play a role are long episodes of fasting, the fulfillment of nutrition (macro and micronutrients) from the start, time to start breastfeeding (ASI), duration of parenteral total administration, the incidence of respiratory distress syndrome and incidence of necrotizing enterocolitis. Zinc is one of the micronutrients which is very risky for deficiency in premature babies. Babies with zinc deficiency experience growth disorders as much as 67%. In India, infants who received zinc supplementation increased after being given 10 days of zinc supplementation and lower mortality rates in the group with supplementation. Very low birth weight babies and bronchopulmonary dysplasia who received zinc supplementation during the week showed good clinical progress and the growth rate also increased. The investigators believe this study has the potential for decreasing infant mortality from its current level and can be a growth indicator for preterm babies.

The study aims to investigate efficacy and safety of nasal mask and prongs used in non-invasive ventilation in newborns by using esophageal pressure transducer. The parameters including ventilation duration, hospitalization duration, pulmonary outcomes and side effects will be evaluated.

Background: Ventilator induced lung injury (VILI) remains a problem in neonatology. High frequency oscillatory ventilation (HFOV) provides effective gas exchange with minimal pressure fluctuation around a continuous distending pressure and therefore small tidal volume. Animal studies showed that recruitment and maintenance of functional residual capacity (FRC) during HFOV ("open lung concept") could reduce lung injury. "Open lung HFOV" is achieved by delivering a moderate high mean airway pressure (MAP) using oxygenation as a guide of lung recruitment. Some neonatologists suggest combining HFOV with recurrent sigh-breaths (HFOV-sigh) delivered as modified conventional ventilator-breaths at a rate of 3/min. The clinical observation is that HFOV-sigh leads to more stable oxygenation, quicker weaning and shorter ventilation. This may be related to improved lung recruitment. This has however to our knowledge not been tested in a clinical trial using modern ventilators. Purpose, aims: To compare HFOV-sigh with HFOV-only and determine if there is a difference in oxygenation expressed as a/A-ratio and/or stability of oxygenation expressed as percentage time with oxygen saturation outside the reference range. To provide information on feasibility and treatment effect of HFOV-sigh to assist planning larger studies. We hypothesize that oxygenation is better during HFOV-sigh. Methods: Infants at 24-36 weeks corrected gestational age already on HFOV are eligible. Patients will be randomly assigned to HFOV-sigh (3 breaths/min) followed by HFOV-only or vice versa for 4 alternating 1-hours periods (2-treatment, double crossover design, each patient being its own control). During HFOV-sigh set-pressure will be reduced to keep MAP constant, otherwise HFOV will remain at pretrial settings. Outcome will be calculated from normal clinical parameters including pulx-oximetry and transcutaneous monitoring of oxygen and carbon-dioxide partial pressures.

Critically ill babies less than 1 month of age have deficient amounts of the antioxidant glutathione and a high incidence of disease associated with oxidative injury compared to healthy babies. These diseases include but are not limited to damage to the eyes, lungs, and intestines. Frequently becoming chronic and potentially life threatening, these diseases result in a significantly decreased quality of life to the infant along with increased costs to the infant's family and society. The amino acid cysteine comprises a third of the tripeptide glutathione and directly influences glutathione production. Older children ill with infection and stable, premature neonates administered cysteine supplementation to their diet have been previously shown to increase their glutathione production and concentrations. Furthermore, cysteine supplementation in the ill children resulted in a quicker resolution of their illness. Although most critically ill babies require IV nutrition (i.e., TPN) before and during their illness, commercially available TPN does not include cysteine as a significant nutrient. Cysteine has effectively become a safe and standard supplement to routine TPN in a few major hospitals in the U.S. The purpose of this study is to evaluate the ability of cysteine supplementation to increase glutathione production and concentrations in critically ill babies. Furthermore, the investigators want to evaluate whether cysteine supplementation results in less oxidative tissue injury and ultimately less severe illnesses. The study will enroll babies admitted to the UCLA Medical Center Neonatal Intensive Care Unit (NICU) and they will be chosen at random and in a blinded fashion to receive either cysteine or non-cysteine supplementation to their routine TPN. Small blood samples along with a single 6 hour infusion of a non-radioactive, stable isotope labeled amino acid will be used to measure the production of glutathione as well as other compounds in the blood to give a quantitative assessment to the severity of illness. Clinical information relevant to the babies' illness and subsequent recovery will be recorded. The results will be compared between cysteine vs. non-cysteine groups and before vs. after individual supplementation. By demonstrating the effect of cysteine supplementation on glutathione production, the incidence and/or severity of disease from oxidative injury in critically ill babies may be decreased if glutathione production is improved.
