Publication Blood Glucose Levels and Characteristics of Hypoglycemia in Low Birth Weight Neonates(Nepal Paediatric Society (JNPS), 2021) Y, Ramesh Bhat; George, Juanitha; Lewis, Leslie; Purkayastha, JayashreeAbstract: Introduction: Low birth weight (LBW) neonates comprising of preterm and small for gestational age (SGA) are at risk of hypoglycemia. Hypoglycemia as such in LBW neonates is not well characterized. We aimed to study the blood glucose levels of these neonates and characterise the hypoglycemia. Methods: Blood glucose levels in singleton neonates with birth weight between 1500 gm and 2499 gm were studied prospectively. Glucose levels were assessed at six hour intervals in the first 48 hours of life and extended if indicated. Glucose level ≤ 45 mg/dL in the first 24 hours and < 50 mg/dL thereafter was considered hypoglycaemia. Results: A total of 320 among 3822 neonates satisfied inclusion criteria; 104 had at least one low glucose reading with an incidence of hypoglycaemia of 32.5%. Preterm neonates constituted 158 (49.4%) and SGA 76 (23.8%). Mean blood glucose values were lowest in the first hour of life (60.1 ± 17.2 mg/dL). Incidence of hypoglycemia was highest within one hour of life followed by day two of life (16.3% and 11.6% respectively). About 86 (82.6%) neonates were asymptomatic. Overall, 75% of neonates had a single episode of hypoglycemia and 25% had a recurrence. Hypoglycaemia was noted in 31.8% of neonates born to diabetic mothers, mostly in the first hour (57.1%). Other risk factors for hypoglycemia included intrapartum fluids, birth weight < 2000 g and polycythemia. Conclusions: About a third of LBW neonates had hypoglycemia; mostly on the first hour and day one of life. Asymptomatic nature of hypoglycaemia in the large majority and recurrent hypoglycemia in 25% cases warrants glucose monitoring in this subgroup.Publication Role of Neutrophil CD64 in the Diagnosis of Neonatal Sepsis(Nepal Paediatric Society (JNPS), 2022) Moideen, Adeel; Barche, Apurv; Andrade, Sneha Jaganathan; Verma, Aditya; Lewis, Leslie Edward; Purkayastha, Jayashree; Hadi, Ayesha ErumAbstract: Introduction: Neutrophil surface CD64 (Cluster of differentiation 64), the highaffinity Fc receptor, is quantitatively up-regulated during infection and sepsis. The diagnostic utility of NCD64 as a reliable marker of neonatal sepsis has not been explored so far. Hence this study has been conducted to compare NCD64 with other currently used infection markers including total leucocyte count, platelet count, absolute neutrophil count (ANC), band:neutrophil ratio and highly sensitive C reactive protein (hs-CRP). Methods: Consecutively born neonates between March 2014 to November 2014 were enrolled with documented sepsis (n = 81), clinical sepsis (n = 35), and no sepsis (n = 87). NCD64 was analyzed by flow cytometry. Results: Sepsis episodes had a higher median CD64 index of 10.35 (Range: 15.88, 6.87) as against 2.97 (Range: 5.53, 1.64) in the control group (p < 0.001). The percentage of NCD64 positive cells was also significantly higher in the sepsis group compared to the control group (63.90 ± 2.67 vs 15.07 ± 1.95; p = 0.001). In the ROC curve analysis NCD64, percentage of NCD64 positive cells had the highest AUC (AUC-0.914) using a cutoff of 28.01%, followed by CD64 mean fluorescence intensity (MFI) with an AUC of 0.850 using a cutoff of 5.54. NCD64 was significantly elevated in the groups with documented and clinical sepsis (p < 0.001). Conclusions: NCD64 is a highly sensitive marker for neonatal sepsis. Prospective studies incorporating NCD64 into a sepsis scoring system are warranted.
