Inflammatory and Hematologic Liver and Platelet (HALP) Scores in Hypothermia-Treated Hypoxic-Ischemic Encephalopathy (HIE).

OBJECTIVE: This study examined systemic inflammatory indices and "Hemoglobin, Albumin, Lymphocyte, Platelet (HALP) scores" in neonates with hypoxic-ischemic encephalopathy (HIE). METHODS: A total of 43 neonates with moderate-to-severe HIE at 36 weeks' gestation were assessed. Systemic inflammatory markers were measured before HT commenced within 0-6 h after birth and between 60 and 72 h during and after therapy or before adjusting for hypothermia. RESULTS: Platelet counts, hemoglobin levels, and platelet indices in the HIE group were significantly lower at both time points (p = 0.001). Both the neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) decreased in the HIE group after hypothermia therapy (p = 0.001). Seizures, PVL, and kidney injuries were associated with higher HALP scores. The AUCs of NLR, PLR, MLR, SII, SIRI, and platelet, neutrophil, monocyte, and lymphocyte Index (PIV) showed significant sensitivity and specified HIE, with area under the curve (AUC) values of 0.654, 0.751, 0.766, 0.700, 0.722, and 0.749, respectively. CONCLUSIONS: A significant difference in systemic inflammatory markers was found between the HIE and control groups after hypothermia treatment, with significant reductions in the MLR and NLR. These markers, particularly MLR, were significant predictors of adverse clinical outcomes including seizures, PVL, and kidney damage.

Perinatal and Neonatal Outcomes of Refugee Infants in a Tertiary Hospital in Turkey.

Background Worldwide, the immigration problem has been increasing due to conflicts. In recent years, Turkey accepted more than 3.8 million refugees from many countries, principally Syria. Aims In this study, we aimed to evaluate the prenatal features and neonatal outcomes of refugees and Turkish controls hospitalized in a tertiary neonatal intensive care unit in Turkey. Materials and methods This retrospective case-control study included comparative data related to populations based on whether they were refugees or not. Their perinatal and neonatal "outcomes" were compared. Results Among the 254 analyzed neonates, 127 were born to refugee mothers, and 127 controls were born to non-refugee Turkish mothers. The refugee rate in our hospitalized neonates was nine, a young mother's age (p=0.010) with a higher rate of adolescent pregnancies at OR 2.78 (95% CI 0.96-8.05) (p=0.032), and consanguineous marriage at OR 0.57 (95% CI 0.32-1.02) (p=0.031) in comparison to non-refugees. The incidence of ABO incompatibility-related hemolytic jaundice (p=0.013) was higher in the refugees. The rate of formula feeding in the first month of life was significantly higher at OR 0.49 (95% CI 0.25-0.92) (p=0.027) in neonates born to refugee mothers. Despite lower perinatal care rates in refugees at OR 7.23 (95%CI 4.12-12.69) (<0.001), preterm morbidities did not differ between refugees and non-refugee preterm infants ≤32 gestational age (p>0.05). Conclusion The importance of breast milk must be strongly encouraged to initiate and promote exclusive breastfeeding for the infants of refugees. Race is still an important risk factor for ABO incompatibility-related hemolytic jaundice. Providing high-quality healthcare is sufficient to prevent worse outcomes in refugee neonates.

Awareness or neglecting the diagnosis of cow milk protein allergy in the neonatal period.

BACKGROUND AND OBJECTIVES: Cow milk protein allergy (CMPA) can mimic surgical disease, gastroenteritis, sepsis, and necrotizing enterocolitis in the neonatal period. For this reason, we aimed to evaluate the clinical features, differential diagnosis, and treatment methods of neonates with CMPA. METHODS AND STUDY DESIGN: The charts of twenty-six breastfed full-term and preterm newborns presenting with CMPA between October 2018 and February 2021 were retrospectively reviewed. The clinical symptoms, laboratory findings, and methods used in diagnosis and treatment were analyzed. RESULTS: CMPA was diagnosed in preterm infants 50% (n=13) at the same rate as in full-term infants 50% (n=13) between 32 to 38 weeks corrected age (median 36 weeks). Among patients with CMPA, 69.2% (n=18) had blood in the stool at the onset. Cow's Milk-related Symptom Score score was found to be significantly higher prior to diagnosis vs. after treatment with the cow milk protein-free mom's milk diet [12(11-13) vs. 4(3-5), p<0.001]. Seventy-two hours after the commencement of the mothers' elimination diet, macroscopic blood in stool disappeared in all patients except one patient. Oral food challenge (OFC) for the diagnosis of CMPA was carried out on all (n=26) neonates. Eosinophilia was seen in 46.2% of patients (n=12). The methemoglobin concentration was 1.1 to 1.5% (median 1.3%). CONCLUSIONS: CMPA should be kept in mind for well-appearing preterm and full-term infants suspected of necrotizing enterocolitis and gastroenteritis, respectively, presenting with bloody stool and eosinophilia. The use of OFC can be implemented since neonates were very well monitored in the neonatal intensive care unit. Treatment is possible by continuing breastfeeding.

Can We Estimate Late-Onset Sepsis by Serial Methemoglobin Levels? An Observational Study in Preterm Neonates.

Objective: To assess serial methemoglobin (MetHb) levels in preterm infants as a possible diagnostic method for late-onset sepsis (LOS). Methods: Preterm infants were assigned into two groups: those with culture-proven LOS and controls. Serial MetHb levels were measured. Results: The MetHb values of the LOS group were found to be significantly increased (p < 0.001). The cutoff value for the detection of LOS was calculated as MetHb > 1.75%, optimized for a sensitivity of 81.9% and specificity of 90%. After antimicrobial therapy, MetHb values were found to decrease significantly (p < 0.001). MetHb had an AUC of 0.810 for mortality using the calculated cutoff of >2% (p < 0.005). Conclusions: MetHb levels increase at the onset of LOS and decrease following treatment. MetHb can be added to other sepsis biomarkers as a rapid infectious process indicator for preterm neonates. MetHb > 2% is associated with LOS mortality.

Carboxyhemoglobin Levels in Preterm Neonatal Late-Onset Sepsis: to Predict or not to Predict.

Background: In this study, we aimed to evaluate carboxyhemoglobin (COHb) levels in diagnosing late-onset sepsis (LOS) in preterm neonates. Methods: The records of culture-positive LOS in preterm neonates hospitalized in NICU from January 2017 to July 2022 were reviewed. COHb levels, C-reactive protein, procalcitonin, and neutrophil to lymphocyte ratio of septic preterm infants were compared to controls. In addition, serial COHb levels measured within six hours before or 24h after blood culture sampling, three to seven days prior, and three to five days after starting antimicrobial therapy were retrieved from patient records. Results: The study included 77 blood-culture-positive preterm infants and 77 non-septic controls. During the LOS episode, the COHb values were found to be significantly increased (median: 1.8, IQR: 1.4-2.5) when compared to the control group (median: 1.2, IQR: 0.8-1.6) (p < 0.001). ROC analysis yielded an AUC of 0.714 for COHb (95% CI: 0.631-0.796, p<0.001). At an optimal cut-off of >1.5%, the test's sensitivity was 64.94%, the specificity was 72.73%, the positive predictive value was 70.42%, and the negative predictive value was 67.47%. LOS led to a dramatic rise followed by a decrease after the initiation of the antimicrobial therapy [1.8 (1.4-2.5)] vs. [1.45 (0.2-4)] p<0.001. Conclusion: COHb levels increased at the beginning of LOS, decreasing in response to antibiotics. When used in conjunction with other sepsis biomarkers, the variation of COHb can be important in evaluating late-onset sepsis episodes in preterm infants.

The Role of Lung Ultrasound as an Early Diagnostic Tool for Need of Surfactant Therapy in Preterm Infants with Respiratory Distress Syndrome.

OBJECTIVE: This study aimed to determine the accuracy of neonatal lung ultrasound (LUS) in predicting the need for surfactant therapy compared with chest X-ray (CXR) in preterm infants. STUDY DESIGN: A prospective double-blind study was conducted in infants with a gestational age <34 weeks with respiratory distress syndrome (RDS) by evaluation with LUS and CXR on admission. RESULTS: Among 45 preterm infants, the median (interquartile range [IQR]) LUS score was 4 (2-8) in the mild RDS group, whereas it was 10 (IQR: 9-12) in the severe RDS group (p < 0.01). The LUS score showed a significant correlation with the need for total surfactant doses (ρ = 0.855; 95% confidence interval [CI]: 0.801-0.902; p < 0.001). A cut-off LUS score of four predicted the need for surfactant with 96% sensitivity and 100% specificity (area under the curve [AUC]: 1.00; 95% CI: 0.97-1.00; p < 0.01). LUS scores predicted continuous positive airway pressure (CPAP) failure accurately (AUC: 0.804; 95% CI: 0.673-0.935; p = 0.001). A significant correlation was observed between LUS scores and positive end-expiratory pressure levels (ρ = 0.782; p < 0.001). During the study period, the CXR number per infant with RDS decreased significantly when compared with preceding months (p < 0.001). The LUS score in the first day of life did not predict the development of bronchopulmonary dysplasia (AUC: 0.274; 95% CI: 0.053-0.495; p = 0.065). CONCLUSION: The LUS score in preterm infants accurately predicts the severity of RDS, the need for surfactant and CPAP failure. The routine use of LUS can decrease the frequency of CXRs in the neonatal intensive care units. KEY POINTS: · LUS is a nonhazardous bedside technique.. · LUS predicts the need for surfactant in preterm infants.. · LUS predicts the severity of RDS better than CXR..

Acute Peritoneal Dialysis in Premature Infants.

OBJECTIVE: This study aimed to investigate the underlying causes and outcomes of less than 1500 g birth weight infants who underwent acute peritoneal dialysis (PD). METHODS: Case records of infants with birthweight less than 1500 g from January 2015 to June 2018 were reviewed. RESULTS: The median (range) birth weight and gestational age of the patients were 720 g (555-1055) and 26 weeks (23-27.5), respectively. Underlying factors for the development of acute kidney injury (AKI) were patent ductus arteriosus (PDA) (15 patients), necrotizing enterocolitis (NEC) (10 patients), sepsis (7 patients), asphyxia (2 patients) and hydrops fetalis (2 patients). Multifunctional 10 F flexible catheter was used for the procedure. Median PD onset time was 7 days (4.5-13.5) and median PD duration was 3 days (1.5-3.5). Overall mortality rate was 81 % (n=17). CONCLUSIONS: Despite high overall mortality, PD is technically feasible in very low birthweight (VLBW) and extremely low birthweight (ELBW) neonates using a multifunctional catheter.
