Transient Tachypnea of the Newborn Is Associated With an Increased Risk of Hospitalization Due to Respiratory Syncytial Virus Bronchiolitis

The use of immature granulocyte and other complete blood count parameters in the diagnosis of transient tachypnea of the newborn

Background

Although Transient tachypnea of the newborn (TTN) is one of the most common causes of respiratory distress in the newborn period, there is no laboratory parameter used to diagnose it. Immatur granulocyte (IG) measurement is accepted as a useful indicator that can be used in early detection of many infectious conditions, especially neonatal sepsis. In this study, it was aimed to determine if IG and other complete blood count (CBC) parameters could be used as laboratory findings supporting TTN diagnosis.

Materials and methods

This study, which was retrospectively planned, was conducted in the neonatal intensive care unit (NICU) a public hospital between January 1, 2019 and January 31, 2021. Randomly selected 50 infants, hospitalized with the diagnosis of TTN, constituted the patient group of the study. 50 infants hospitalized with the diagnosis of hyperbilirubinemia and did not have any additional problems accepted as the control group. IG and other CBC parameters of infants in the patient and control groups were compared in the study.

Results

There was no significant difference between the patient and control groups in terms of demographic data and types of delivery (p > 0.05). The rate of delivery by elective cesarean section (C/S) was significantly higher than the rate of normal spontaneous vaginal (NSV) delivery in the patient group (p < 0.001). The IG number and percentage, WBC (white blood cell) count, RDW (red cell distribution width), number and percentage of NRBC (nucleated red blood cell), neutrophil and lymphocyte ratio, count and percentage of basophil and PLR (platelet/lymphocyte ratio) of the patient group was significantly higher than the control group (p < 0.05).

Conclusion

According to the findings obtained in the study, it was concluded that IG and other CBC parameters may be used to support clinical and imaging findings to diagnose transient tachypnea of the newborn.

•

There was no significant difference between the patient and control groups in terms of demographic data and types of delivery.

•

The rate of elective cesarean section (C/S) was significantly higher than normal spontaneous vaginal (NSV) delivery in the patient group.

•

The IG number and percentage, WBC count, RDW, number and percentage of NRBC, neutrophil and lymphocyte ratio, count and percentage of basophil and PLR of the patient group was significantly higher than the control group.

•

IG and other CBC parameters can be useful to support clinical and imaging findings to diagnose TTN.

Human Epididymis Protein 4 Levels in Neonates with Respiratory Disorder

Results

There were no differences found in the HE4 levels determined for the mothers' blood samples and umbilical cord blood samples in all investigated groups. In comparison with healthy children, the elevated HE4 levels were observed in neonates with TTN. Significant positive correlation between HE4 and CRP as well as PCT levels was observed in all investigated neonates. The receiver operating characteristic (ROC) curve analysis demonstrated the cut-off value for the serum HE4 in the researched neonates at the level of 318.5 pmol/L, yielding the sensitivity of 73.9% and specificity of 66.7% for the early diagnosis of TTN.

Conclusions

Serum HE4 could be considered as a candidate biomarker for the early diagnosis of pulmonary dysfunction in the newborns.
