Clinical trials

The purpose of this study is to determine whether continuous glucose monitoring (CGM) improves the detection and management of neonatal hypoglycaemia in newborns of mothers with insulin-treated gestational diabetes.

The aim of the study is to evaluate the effectiveness and safety of fecal microbiota transplantation (FMT) in reducing gastrointestinal (GI) and behavioral symptoms in children with autism spectrum disorder (ASD). Children with ASD often experience GI problems such as constipation, diarrhea, and abdominal pain. These symptoms can negatively affect their daily life and behavior. Recent research suggests that the gut microbiota-the community of bacteria and other microorganisms living in the intestines-plays an important role in digestion, immunity, and communication with the brain through the gut-brain axis. Modifying the gut microbiota may help improve GI symptoms and possibly behavioral functioning. FMT involves giving a preparation containing gut microbiota from a healthy donor after bowel cleansing. The product used in this study is MBiotix HBI Caps, produced by Human Biome Institute. A placebo (inactive substance) will also be used for comparison. Both will be given as frozen oral capsules that look identical. 20 children aged 6-12 years will take part. Participants will be randomly assigned to receive either the microbiota preparation or placebo. The study includes several visits over about 6 months. Before the first dose, every child will undergo bowel cleansing with a special preparation (Polyethylene Glycol, PEG). During the study, participants will be asked to keep a symptom diary, complete questionnaires, and record child's diet. Biological samples (stool, urine, saliva) will be collected at specific time points for analysis. Every child will also be assessed by a psychologist before the study begins and again during the study using standardized tools (Autism Diagnostic Observation Schedule, Second Edition, ADOS-2) to evaluate behavioral functioning and quality of life.

levated levels of S100B protein are a well-established marker of central nervous system (CNS) damage. Fetal anemia resulting from hemolytic disease of the fetus and newborn (HDFN) often necessitates intrauterine transfusions (IUTs) and represents a significant risk factor for CNS injury. However, it remains uncertain whether S100B protein levels can reliably predict which fetuses are at higher risk for CNS complications in this context. Furthermore, the potential role of measuring S100B concentrations before IUT in prenatal assessments, and its relationship to the severity of anemia and fetal cerebral blood flow, remains poorly understood. This study aims to investigate the concentration of S100B protein in cord blood from newborns with HDFN-related fetal anemia requiring IUT. The study group comprises pregnancies complicated by HDFN with abnormal middle cerebral artery (MCA) blood flow, indicating the need for IUT. In this group, S100B protein levels will be measured before each IUT, with additional measurements if further transfusions are required. The control group consists of pregnancies with HDFN that do not require IUT. Cord blood samples will be collected at birth to evaluate S100B protein levels in both groups. Additionally, fetal MCA blood flow will be monitored, and in the study group, fetal hemoglobin and hematocrit levels will be assessed before each IUT. The primary endpoints of the study include the measurement of cord blood S100B protein levels before IUT in the study group and at birth in both groups. Secondary endpoints will explore the potential correlations between S100B protein levels and umbilical cord blood gas parameters (e.g., pH, BE, lactate), fetal cerebral blood flow parameters (e.g., MCA-PSV values), and blood count parameters (e.g., hemoglobin and hematocrit levels), both before IUT in the study group and after birth in both groups.

S100B protein is a biomarker that increases following central nervous system (CNS) damage. Measuring this protein's levels may allow for the early identification of infants at high risk for developmental abnormalities, such as fetal growth restriction (FGR), even on the first day of life, in a non-invasive manner. Early detection could enable timely interventions and rehabilitation, potentially improving the child's prognosis and long-term outcomes. This study investigates two groups of full-term pregnancies: a study group with prenatally diagnosed late FGR, and a control group with normal fetal growth. Following delivery, cord blood samples from both groups will be analyzed for S100B protein concentrations, pH, base excess (BE), and lactate levels. Additionally, fetal blood flow parameters in the umbilical artery (UA), uterine arteries (UtA), ductus venosus (DV), and middle cerebral artery (MCA) will be monitored via ultrasound within 48 hours before delivery. This study aims to compare S100B protein concentrations in umbilical cord blood between the two groups and to assess correlations with fetal Doppler parameters, pH, BE, and lactate levels in cord blood gas analysis. Ultimately, we seek to determine the effectiveness of S100B protein concentration as a biomarker for diagnosing fetal CNS hypoxia- ischemia in FGR-affected children, compared to those with normal growth.
