A comparison of different dosing regimen of intravenous paracetamol for hemodynamically significant patent ductus arteriosus closure in premature neonates <32 weeks: a prospective observational study.

OBJECTIVE: To compare the efficacy of low vs conventional dose intravenous paracetamol in early closure of haemodynamically significant patent ductus arteriosus within 7 days of life. METHODS: Preterm infants (<32 weeks of gestation) having echocardiographic evidence of hsPDA were given low dose (15 mg/kg initially followed by 7.5 mg/kg every 6 hourly) vs conventional dose (15 mg/kg every 6 hourly) for 5-7 days. RESULTS: In total, 56 infants (28 in each group) were enrolled. Ductal closure was achieved in 96% infants in the low-dose group and 100% infants in the conventional group (P = 1.00). Secondary outcomes, including ductal reopening and need for the second course of medical treatment (21% vs 3.5%, P = 0.1), median duration of hospital stay [30 (15, 43.5) vs 27 (18.5,45), P = 0.64], cumulative oxygen requirement [17.5 (7, 25) vs 14 (8.5, 25), P = 0.89], mortality (10.7% vs 25%, P = 0.29) and other morbidities, were comparable in both the groups. Median paracetamol levels were comparable in both the groups [53.4 µg/L (47, 2,70) vs 62.5 (55.6, 81.2), P = 0.67]. CONCLUSION: Low-dose paracetamol was non-inferior to conventional dose paracetamol for early ductal closure in preterm infants.

Diagnostic Accuracy of Point-of-Care Testing of C-Reactive Protein, Interleukin-6, and Procalcitonin in Neonates with Clinically Suspected Sepsis: A Prospective Observational Study.

OBJECTIVE: Sepsis often prompts clinicians to start empirical antibiotics in suspected neonates while awaiting diagnosis. The next-generation testing with point-of-care (POC) techniques offers a lead-time advantage that could bridge the gap by providing a timely diagnosis. MATERIALS AND METHODS: We conducted a prospective diagnostic study in 82 neonates enrolled between May and October 2022 in a level III neonatal intensive care unit. All neonates with a new episode of clinically suspected sepsis were included. Diagnostic accuracy of POC testing of C-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin (PCT) with standard laboratory methods was performed. RESULTS: The mean gestation age and birth weight of the neonates were 33.17 ± 4.25 weeks and 1,695.4 ± 700.74 grams, respectively. Most neonates were preterm (75%) with nearly equal proportions of early (51.22%) and late-onset (48.78%) sepsis. The POC CRP correlated well with standard CRP (r = 0.8001, 95% CI: 0.706-0.867, p < 0.0001). Among the three biomarkers, CRP had the maximum diagnostic accuracy (area under the curve [AUC] - 0.73) followed by PCT (AUC - 0.65) and IL-6 (0.55). There was no significant difference in the diagnostic accuracy of CRP (p = 0.46), PCT (p = 0.29), and IL-6 (p = 0.60) in early- and late-onset sepsis. The mean time for POC estimation of IL-6, PCT, and CRP was 12 ± 3 min which was significantly less compared to 366 ± 61 min for standard techniques (p < 0.001). CONCLUSION: POC CRP correlates well with standard techniques of estimation, and CRP alone and in combination with PCT has good diagnostic accuracy in neonatal sepsis.

Epidermolysis bullosa in a mother-infant dyad.

Epidermolysis Bullosa is an inherited mechanobullous disorder which presents in the neonatal period as blistering skin lesions. In this case report, we describe an uncommon presentation of Epidermolysis Bullosa Simplex in a term infant, weighing 2640 g, born to a mother who was also diagnosed with Epidermolysis Bullosa Pruriginosa during the course of the evaluation of her newborn. The clinical situation presented us with a unique dilemma with regard to routine newborn care practices including handling, skin and diaper care. Though the presentation was typically characteristic of EB, we illustrate with images the diagnostic modalities and challenges faced in the hospital while caring for this fragile skin in a low and middle-income country's neonatal intensive care unit. This is the first reported case of a neonate with Epidermolysis Bullosa Simplex born to a mother with Epidermolysis Bullosa Pruriginosa.

A case report on umbilical artery catheter embolization in a neonate, and its surgical management.

Umbilical arterial and venous catheters are used widely in management of critically ill neonates. Being delicate, they can get inadvertently damaged by needles, scissors, or tight purse-string sutures during insertion and removal. Umbilical artery catheter embolization is a rare and dreaded complication, with less than 15 cases reported to date. We describe a term neonate, in whom a 3.5-Fr umbilical artery catheter, accidentally broken and dislodged, was surgically retrieved through right common iliac arteriotomy, safely and completely. Direct surgical retrieval of umbilical catheters while avoiding attempts at local exploration maybe considered a first line in management, particularly if endovascular facilities are unavailable or inaccessible.

Multisystem inflammatory syndrome in neonates (MIS-N): a systematic review.

Recently, a new pattern of multisystem inflammatory syndrome following an infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has emerged globally. The initial cases were described in the adult population followed by sporadic cases in the pediatric population also. By the end of 2020, similar reports were recognised in the neonatal age group. The purpose of this study was to systematically review clinical characteristics, laboratory parameters, treatment, and outcomes of neonates with multisystem inflammatory syndrome in neonates (MIS-N). A systematic review was conducted after registering with PROSPERO and electronic databases including MEDLINE, EMBASE, PubMed, SCOPUS, Google Scholar, and Web of Science were searched from January 1st 2020 till September 30th 2022. A total of 27 studies describing 104 neonates were analysed. The mean gestation age and birth weight was 35.9 ± 3.3 weeks and 2255.7 ± 783.7 g respectively. A large proportion (91.3%) of the reported cases belonged to the South-East Asian region. The median age of presentation was 2 days (range: 1-28 days) with cardiovascular system being the predominant system involved in 83.65% followed by respiratory (64.42%). Fever was noted in only 20.2%. Commonly elevated inflammatory markers were IL-6 in 86.7% and D-dimer in 81.1%. Echocardiographic evaluation suggested ventricular dysfunction in 35.8% and dilated coronary arteries in 28.3%. Evidence of SARS-CoV-2 antibodies (IgG or IgM) was seen in 95.9% neonates and evidence of maternal SARS-CoV-2 infection, either as history of COVID infection or positive antigen or antibody test, was noted in 100% of the cases. Early MIS-N was reported in 58 (55.8%) cases, late MIS-N in 28 (26.9%), and 18 cases (17.3%) did not report the timing of presentation. There was a statistically increased proportion of preterm infants (67.2%, p < 0.001), and a trend towards increased low birth weight infants, in the early MIS-N group when compared to the infants with late MIS-N. Fever (39.3%), central nervous system (50%), and gastrointestinal manifestations (57.1%) were significantly higher in the late MIS-N group (p = 0.03, 0.02, 0.01 respectively). The anti-inflammatory agents used for the treatment of MIS-N included steroids 80.8% which were given for a median of 10 (range 3-35) days and IVIg in 79.2% with a median of 2 (range 1-5) doses. The outcomes were available for 98 cases, of whom 8 (8.2%) died during treatment in hospital and 90 (91.8%) were successfully discharged home.   Conclusion: MIS-N has a predilection for late preterm males with predominant cardiovascular involvement. The diagnosis is challenging in neonatal period due to overlap with neonatal morbidities and a high risk of suspicion is warranted, especially in presence of supportive maternal and neonatal clinical history. The major limitation of the review was inclusion of case reports and case series, and highlights need of global registries for MIS-N. What is Known: • A new pattern of multisystem inflammatory syndrome following SARS-CoV-2 infection has emerged in adult population with sporadic cases now being reported in neonates. What is New: • MIS-N is an emerging condition with a heterogeneous spectrum and has a predilection for late preterm male infants. Cardiovascular system is the predominant system involved  followed by respiratory, however fever remains an uncommon presentation unlike other age-groups. There are two subtypes based on timing of presentation, with early MIS-N being reported more in preterm and low-birth weight infants.

A single-center observational study on clinical features and outcomes of 21 SARS-CoV-2-infected neonates from India.

Coronavirus disease-19 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is an ongoing pandemic with significant morbidity and mortality. Neonates represent a vulnerable population, in which we have limited knowledge of its natural history, optimal management, and outcomes. In this retrospective observational study from a low-middle-income setting, clinical characteristics and outcomes of neonatal SARS-CoV-2 infection were evaluated. We report an incidence of 10.6% of SARS-CoV-2 infection (21 neonates), among a group of 198 neonates with suspected infection. Most of the SARS-CoV-2-infected neonates were term (80.9%) and none required any resuscitation. The infection was detected by a positive nasopharyngeal swab reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV-2. Neonatal COVID-19 manifestations developed in one-third (33.3%) of the infected neonates. Most of them demonstrated the involvement of respiratory (33.3%) and gastrointestinal systems (4.8%). Laboratory parameters suggested multi-systemic involvement, with elevated creatine kinase (CK) (76.2%), creatine kinase-myocardial band (CK-MB) (76.2%), and lactate dehydrogenase (LDH) (71.4%) levels. Supportive treatment was given to infected neonates with intensive care required in six neonates (28.6%). This included four preterm and two term neonates, of which two received non-invasive and one received invasive ventilation with intra-tracheal surfactant instillation. IgM antibodies against COVID-19 were detected in one neonate. All neonates with COVID-19 improved and were successfully discharged.Conclusion: SARS-CoV-2 in neonates has a wide clinical spectrum. Further studies are needed which are adequately powered to completely understand the course of this infection in neonates, its implications not only in the neonatal period but also on long-term follow-up. What is Known: • SARS-CoV-2 infection has a predilection for all age groups but with limited literature on clinical profile, outcomes, and long-term follow-up in neonates. What is New: • SARS-CoV-2 infection in neonates has a wide clinical spectrum and displays a significant overlap with common neonatal conditions. • Most neonates with COVID-19 improved with supportive care, though a subset required intensive care, emphasizing the need for cautious monitoring and management.
