ABSTRACT
BACKGROUND: Retinopathy of prematurity (ROP) is an important cause of visual morbidity among preterm infants. The objective of the study was to assess the relationship between the initial hematological parameters of the complete blood count (CBC) and ROP development in preterm neonates. METHOD: This retrospective cohort study was conducted in a neonatal intensive care unit in Odisha. The hematological parameters of the CBC conducted within the first 48 hours of age, demographic characteristics, neonatal morbidities, and ROP screening findings of preterm neonates (gestational age <34 weeks) were analyzed. Independent risk factors associated with ROP development were identified in a multivariate logistic regression model. RESULT: A total of 43 (29.1%) out of 148 neonates had any of the ROP stages (stage 1-26, 2-08, and 3-09). Birth weight (aOR 0.003; 95% CI 0.00, 0.11);hemoglobin (Hb) level (aOR 0.70; 95% CI 0.54, 0.90); presence of respiratory distress syndrome (RDS) (aOR 7.61; 95% CI 1.5, 36.39); and need for packed red blood cell (PRBC) transfusion (aOR 4.26; 95% CI 1.1, 16.44) were independently associated with ROP development. The odds of ROP were higher among the neonates with initial Hb 10.5-15.4 g/dL (OR (95% CI) 3.7(1.5, 8.9), p=0.003) and for neonates with Hb 15.4-17.3 g/dL (OR (95% CI) 2.5(1.01, 6.16), p=0.047) in comparison to neonates with initial Hb >17.3 g/dL. CONCLUSION: Preterm neonates with a lower level of Hb during the early postnatal days are at higher risk for ROP development and need to be prioritized for screening.
ABSTRACT
Background and objective Malnutrition remains a significant cause of childhood morbidity and mortality worldwide. Severe acute malnutrition (SAM) profoundly affects immune development, physiological functions, and metabolic processes, increasing susceptibility to infections. This study aimed to investigate the prevalence of acute bacterial infections and their antibiotic sensitivity patterns among SAM children admitted to a tertiary care hospital. Methodology This prospective observational study was conducted at the pediatric department of Kalinga Institute of Medical Sciences (KIMS), Bhubaneswar, Odisha, from November 2020 to October 2023. The study included 95 children aged 6-59 months meeting WHO criteria for SAM. Participants underwent comprehensive demographic assessments, clinical evaluations, and relevant laboratory tests, including blood and urine cultures with sensitivity testing. Results The study found that 82.1% of children had weight-for-height below -3 standard deviations, and 84.21% had mid-upper arm circumference below 115 mm, confirming SAM diagnosis. The most prevalent infections were acute gastroenteritis (47.3%), respiratory tract infections (46.3%), bacteremia (27.4%), and urinary tract infections (26.3%). Positive urine cultures were observed in 25 cases (26.3%), predominantly among females (68%). Escherichia coli (40%) and Klebsiella pneumoniae (24%) were the most common organisms isolated from urine, with high sensitivity to gentamicin (76%) and meropenem (72%). Blood cultures were positive in 26 cases (27.36%), with Staphylococcus aureus ââââââ(30.76%) and Klebsiella pneumoniae (23%) being predominant. Blood isolates showed significant sensitivity to vancomycin (73%), meropenem (69.2%), and linezolid (65.3%). Conclusion Acute gastroenteritis, respiratory tract infections, bacteremia, and urinary tract infections are prevalent among SAM children. Staphylococcus aureus was frequently isolated from blood cultures, while Escherichia coli were predominant in urine cultures. High sensitivity of urinary isolates to gentamicin and meropenem, and of blood isolates to vancomycin, meropenem, and linezolid, highlights effective antibiotic choices. These findings emphasize the importance of tailored antimicrobial therapy based on local sensitivity patterns to improve clinical outcomes in SAM children.
