About

Breast milk jaundice (BMJ) is the main cause of neonatal hyperbilirubinemia. Excessive serum unconjugated bilirubin level will not only cause the interruption or early termination of breastfeeding, but also cause kernicterus. Which can cause long-term dysfunction in infants. But for a long time, BMJ diagnosis has relied on clinical exclusive methods, lack of objective and reliable laboratory indicators. Which leads to misdiag. This project is a single-center, prospective nested case-control study. It is planned to establish a neonatal BMJ cohort. According to the admission criteria, 100 cases of early-onset BMJ and late-onset BMJ will be completed, and 100 healthy controls collected during the same period. , Compare the detection results of fecal miRNA and intestinal flora of the two groups of BMJ children and healthy controls, draw the ROC curve of the joint diagnosis, conduct research on the combined diagnostic value of fecal miRNA and intestinal flora analysis, and try to find the feasibility and practical value of diagnostic markers for feces in infants with BMJ.

Full description

This project is a single-center, prospective nested case-control study to investigate feasibility and practical value of diagnostic markers in infants with BMJ.

According to the admission criteria, 100 cases of early-onset BMJ, 100 late-onset BMJ and 100 healthy controls will be selected. Their feces, peripheral venous blood and mothers' breast milk were collected for further testing. Compare the detection results of fecal miRNA and intestinal flora of the two groups of BMJ children and healthy controls, draw the ROC curve of the joint diagnosis, conduct research on the combined diagnostic value of fecal miRNA and intestinal flora analysis.

This study is to find the objective and reliable laboratory indicators to diagnose BMJ.

Trial design

300 participants in 3 patient groups

early-set BMJ group

Description:

Infants were admitted to our hospital at 4-7 days of age and were followed up to 28 days. Other pathological jaundice factors were excluded.Those who met the criteria were the early-onset BMJ group.

Treatment:

Diagnostic Test: Neonatal hyperbilirubinemia

late-onset BMJ group

Description:

Infants were admitted to our hospital after 7 days of age and were followed up to 28-42 days or until the jaundice disappeared. Other pathological jaundice factors were excluded..Those who met the criteria were late-onset BMJ

Treatment:

Diagnostic Test: Neonatal hyperbilirubinemia

healthy control

Description:

During the same period, the healthy newborns who were born in the obstetrics department of our hospital. These newborns were mainly breastfed or breastfed, and grew well. They were enrolled at 7-14 days of age and were followed up to 28-42 days without pathological jaundice.

Treatment:

Diagnostic Test: Neonatal hyperbilirubinemia
