This is the first nationwide study aimed to evaluate in-hospital mortality and comorbidities of extremely low birth weight (ELBW) infants in Thailand between 2015–2020. Data of ELBW infants were collected from the National Health Coverage Scheme. The incidence of ELBW Thai infants was 1.75 per 1000 live births. Sixty-five percent of ELBW infants were delivered in tertiary-care facilities, with 63% surviving until discharge. In-hospital mortality was 36.9%. Non-invasive respiratory supports were documented in just 17.6% of the study population, whereas total parenteral nutrition was used in 52.3% of neonates. There were several comorbidities, with the three most frequent including respiratory distress syndrome (70.7%), neonatal jaundice (66.7%), and sepsis (60.4%). The median hospitalization cost for one ELBW infant who survived was 296,438.40 baht ($8719). Conclusion: Thailand had an acceptable ELBW infant survival rate (63%), but comorbidities remained particularly severe and cost one hundred times the median hospital cost for one ELBW infant that survived in comparison to a normal newborn infant. Better health outcomes require strategies to raise awareness of the issues and the appropriate implementation of evidence-based solutions, particularly improving neonatal care facilities, as well as early referral of high-risk pregnant women and neonates, which will aid in the future reduction of neonatal morbidities and mortalities.

Background Neonatal jaundice is most commonly caused by blood group incompatibility but may also result from hereditary elliptocytosis (HE) associated with heterozygous SPTB mutations. Methods A retrospective descriptive study was conducted among 1,584 neonates presenting with jaundice over a 3-year period. Results Seventy-six neonates (4.8%) were diagnosed with HE, all carrying heterozygous SPTB mutations (Providence variant, n = 67; Buffalo variant, n = 9). Five had coexisting hemoglobinopathies. Early-onset jaundice occurred in 71 patients, with a median onset of 38 h. Peak total bilirubin levels ranged from 12.2 to 22.3 mg/dL. Most neonates required single phototherapy; seven required double phototherapy, and none underwent exchange transfusion. Anemia developed in 23 patients, of whom 17 required red cell transfusion. Conclusion HE is an under-recognized cause of early-onset neonatal jaundice and anemia. Despite early hyperbilirubinemia, most neonates have a benign clinical course with minimal long-term complications and infrequent need for transfusion.

Objective: To determine the incidence, causative pathogens, risk factors, and clinical outcomes of early-onset sepsis (EOS) in very preterm (gestational age < 32 weeks) and very low birth weight (birth weight < 1500 g) neonates. Methods: This retrospective study analyzed data from the Thai Neonatal Network registry (2019–2024; total 22 neonatal units). EOS was defined as bacteremia or bacterial meningitis within 72 h of birth. Results: Among 792 neonates (median [interquartile range] gestational age, 28 [26–29] weeks; median [interquartile range] birth weight, 960 [779–1190] g), the incidence of EOS was 4.0% (n = 32). Predominant pathogens were Escherichia coli (n = 10) and Acinetobacter baumannii (n = 9). Antibiograms showed high non-susceptibility for E. coli and A. baumannii to gentamicin (44.4% and 83.3%, respectively) and cefotaxime (37.5% and 75.0%, respectively). Although E. coli remained susceptible to amikacin and meropenem (100%), A. baumannii exhibited extensive resistance (66.7% and 83.3%, respectively). Multivariable analysis identified chorioamnionitis (adjusted odds ratio [aOR] 1.12; 95% confidence interval [CI]: 1.07–1.18) and 5 min Apgar score < 7 (aOR 1.05; 95% CI: 1.02–1.18) as significant risk factors. EOS was independently associated with increased early neonatal mortality within 7 days of life (aOR, 1.26; 95% CI: 1.16–1.36). Conclusions: The incidence of EOS is high among very preterm infants in Thailand and significantly increases mortality rates. The prevalence of multidrug-resistant A. baumannii in neonatal EOS is a critical concern that limits the efficacy of empirical treatments. These findings highlight the urgent need for targeted interventions and enhanced antimicrobial stewardship to improve neonatal survival rates.
