Identification of a Pool of miRNA to Improve Early Management of Perinatal Asphyxia and Hypoxic Ischemic Encephalopathy

Hypoxic-ischemic encephalopathy is the most common cause of neurological damage in the neonatal period. It has an incidence of about 1.5-2.5% of livebirths in developed countries. It is associated with a high rate of mortality and morbidity. Major neurological outcomes such as cerebral palsy, mental retardation, learning disabilities, epilepsy occur in approximately 25% of survivors. The diagnostic and prognostic tools currently available for enrollment have limitations and additional reliable biomarkers are needed for all phases of clinical management. Sarnat staging has taken on a role in identifying those infants who may benefit from treatment of hypothermia, resulting in the need for neurological evaluation and staging within 6 hours of life. Therapeutic hypothermia is still the best therapeutic treatment. A new tool in neuroscience research is represented by micro-ribonucleic acid (microRNA) profiling. The presence of microRNAs in blood, urine and saliva and the ability to measure their levels non-invasively has opened new doors in the search for peripheral biomarkers for the diagnosis and prognosis of neurodegenerative diseases and also as possible pharmacological targets. The aim of the present study is to analyze a specific cluster of miRNAs selected from data obtained by macroarray (NGS Pannel) on the entire microRNAome in healthy newborns with normal cord arterial pH value (7.26-7.35) as control cases and in newborns with fetal metabolic acidosis with a pH threshold value lower than 7.12 of the blood gas analysis from cord arterial blood. This latter group will be further stratified into two groups, neonates who will practice therapeutic hypothermia according to current guidelines and a further group who will not practice therapeutic hypothermia. This study will make a further international contribution in evaluating and identifying the potential of microRNAs as diagnostic and prognostic biomarkers in perinatal asphyxia and hypoxic ischemic encephalopathy. Furthermore, the study aims to identify specific microRNA sequences as new possible markers to be used as an additional parameter for the enrollment of therapeutic hypothermia, especially in cases of mild hypoxic-ischemic encephalopathy.

Early Hydrocortisone Versus Regular Treatment in Shock in Extremely Preterm Neonates - an Open Randomized Controlled Trial

The goal of this clinical trial is to determine the effectiveness of early use of hydrocortisone (since the diagnosis of shock) for its resolution within the first 72 hours in premature infants under 1,500 g. The main questions it aims to answer are: * Does the early use of hydrocortisone help solve shock in preterm infants under 1500 g faster than the standard treatment? * Does the early use of hydrocortisone help prevent death within the first seven days of presentation of shock in comparison to premature infants who receive regular treatment? Researchers will compare the early use of hydrocortisone plus the standard treatment to solve shock against just standard treatment. Participants will: * Be randomized to receive standard treatment for shock according to their neonatologist or this standard treatment plus hydrocortisone as soon as the diagnosis is done and treatment is started. * Be followed either until shock is solved or if they present death due to this event of shock.
