In the face of the emergence of COVID-19, the multisystem inflammatory syndrome in neonates, which is associated with severe acute respiratory syndrome-related coronavirus, has increasingly been reported. The clinical presentation and evolution of multisystem inflammatory syndrome (MIS) mimics neonatal diseases such as sepsis. Because of the similarities, these cases present clinical and laboratory peculiarities that necessitate distinguishing them from more common neonatal illnesses to reach a consensus on this new disease in the future. Here, we present two cases from India in which neonates had MIS-like manifestations but were later diagnosed with sepsis and metabolic disorder, posing a management dilemma.

| Introduction|| |
Increasing case reports of children suffering from potentially life-threatening pediatric inflammatory multisystem syndrome, also known as multisystem inflammatory syndrome in children (MIS-C), have been described amid the COVID pandemic. MIS-C is a new disease in children, with no known cause. It is thought to be the result of immune dysregulation caused by severe acute respiratory syndrome-related coronavirus (SARS-CoV-2) exposure. In contrast to MIS-C, where SARS-CoV-2 infection and multisystem inflammation occur in the same patient, a few case reports suggest neonatal multisystem inflammation (MIS-N) occurs because of maternal SARS-CoV-2 infection. A case series of twenty neonates with multisystem involvement, hyperinflammatory syndrome, and positive anti-SARS-CoV-2 Immunoglobulin G (IgG) antibodies was recently published, emphasizing the severity of the disease. Diagnosis and management of MIS-N remain a huge gray area, which could lead to overdiagnosis and overtreatment of neonates with clinical manifestations of MIS.,,, Hence, differentiating MIS-N from other causes is utmost important for providing the quality neonatal care. We present a case series of two neonates from India who had clinical manifestations such as MIS-N but a different underlying cause.
| Case Reports|| |
A male baby born to a primigravida mother by premature onset of spontaneous labor (gestation: 34 + 4 weeks and weight: 1954 g) was admitted to the newborn intensive care unit for transient tachypnea of the newborn, which resolved in 4 h. The mother had a history of COVID-19 infection 2 months before delivery. There was no history of chorioamnionitis or prolonged rupture of membranes. APGAR score at 1 and 5 min was 8/10 and 9/10, respectively. The neonate did well during the first 2 days of life and accepted oral feeds. On day 3, he developed tachycardia (heart rate: 230–250 beats per minute [BPM]). Electrocardiogram showed supraventricular tachycardia (SVT). There was no response to adenosine. The baby was cardioverted because of his cardiovascular instability (poor peripheral pulses, mottling, and significant cardiac dysfunction). For 3 h, sinus tachycardia (HR: 200–220 BPM) was maintained. Meanwhile, blood investigations revealed elevated inflammatory markers (C-reactive protein, procalcitonin, ferritin, and D-dimer), as well as positive serology for COVID antibodies [Table 1] and [Table 2]. IgG and total against SARS-CoV-2 were detected using VIDAS® SARS-COV-2 kits (BioMerieux SA, Marcy-I'Etioile, France), with MINIVIDAS using enzyme-linked fluorescent assay (ELFA). The neonate had generalized tonic convulsions hence was administered phenobarbitone.

The fever and underlying metabolic disturbance, that is, metabolic acidosis, were treated. Intravenous immunoglobulin (IVIG) was administered due to the likely diagnosis of MIS-N. Because sepsis could not be ruled out, intravenous (IV) methylprednisolone was not administered. The neonate did, however, develop tachyarrhythmia again, and this time, it did not respond to adenosine or cardioversion. Because of the refractory SVT, IV amiodarone was administered. As no clinical benefit was observed 2 h after amiodarone administration, IV methylprednisolone was given under the cover of broad-spectrum antibiotics – meropenem and vancomycin. Within 3 h, sinus rhythm was established, and hemodynamic stability improved significantly. Because clinical sepsis remained a possibility, additional methylprednisolone doses were withheld. Patient's blood and cerebrospinal fluid culture grew Group B Streptococcus (GBS). The final diagnosis was early-onset sepsis. The neonate was extubated on day 5, weaned off respiratory support by day 16, and discharged on day 25. [Figure 1] depicts a detailed timeline of clinical presentation and management.
A male newborn with asphyxia was referred for further management. He was delivered by emergency cesarean section at 36-week gestation due to fetal distress. At 1 and 5 min, the APGAR score was 3/10 and 5/10, respectively. Mother was gravida 4, had two spontaneous abortions and had a history of intrauterine death. The baby had moderate hypoxic ischemic encephalopathy (HIE) at the time of admission. Therapeutic hypothermia (TH) was started within 6 h of birth. The neurology improved from moderate stage of HIE to mild over the next 24 h, but there was an increased need for respiratory support, progressive metabolic acidosis, and hemodynamic instability in the form of hypotension. Hence, TH was discontinued, and controlled rewarming was done. The laboratory parameters were suggestive of multi-organ dysfunction. The neonate's serology for COVID antibodies was positive. IgG and total against SARS-CoV-2 were detected using VIDAS® SARS-COV-2 kits (BioMerieux SA, Marcy-I'Etioile, France), with MINIVIDAS using ELFA. The blood culture was negative. The neonate clinically was diagnosed to have MIS [Table 1] and [Table 2]. IVIG was administered. However, possibility of sepsis and inborn errors of metabolism (IEM) could not be ruled out, hence, methylprednisolone was not administered. The metabolic workup, which included blood for tandem mass spectroscopy and urine for gas chromatography–mass spectrometry, was ordered. The baby's clinical condition worsened over time, and he died on the 4th day of life. He was later diagnosed with 3-methyl glutaconic aciduria.
| Discussion|| |
Traditionally, any sick neonate with positive septic screen or raised inflammatory markers is considered to have probable sepsis or sepsis mimic-like IEM, etc. However, today amid pandemic, MIS-N appears to be the closest differential.,, Because the management for these two conditions is so different, distinguishing between MIS and sepsis or sepsis mimics becomes critical. The practical issue is that laboratory results supporting the MIS diagnosis are available within a few hours, whereas blood culture takes days, and the yield is also dependent on many factors.
The most difficult situation arises when the neonate suffers from a life-threatening emergency, as in the two cases described here. The neonate in first case had SVT, developed fever, and had positive inflammatory markers [Table 1]. The second case had progressive organ dysfunction and raised inflammatory markers. Both neonates were managed as per the standard protocol. Anti-SARS-CoV-2 IgG antibodies were positive in both the cases. In the MIS-N case series published by Pawar et al., 90% of the neonates had cardiac manifestations. Arrhythmia was observed in 44% and one neonate had asphyxia and died of multi-organ dysfunction. In both cases, there was no conclusive point-of-care test to rule out sepsis or metabolic disorder, and the only evidence was positive anti-SARS-CoV-2 antibodies.
Clinical improvement was seen in first case, whereas the neonate in second case had rapid downhill. The neonate in first case was later diagnosed with GBS sepsis and that in the second case was diagnosed with 3-methyl glutaconic aciduria. Both neonates had life-threatening clinical features warranting urgent treatment in the form of IVIG and methylprednisolone. It was not possible to rule out sepsis or metabolic disorder on the day of clinical deterioration. Diagnosis of GBS needs advanced microbiology facilities. Many centers in India may not have the advanced culture techniques, so GBS infection could have easily been missed and mislabeled as MIS-N. Similarly, in the second case, the result of metabolic work up was available after 7 days. As the clinical progress and history pointed toward probability of metabolic disorder, the work up was sent.
In both cases, although the clinical features and laboratory investigations were initially pointing toward diagnosis of MIS-N, we treated both babies as sepsis mimics, with close watch on the clinical progression.
| Conclusion|| |
Differentiating MIS from sepsis mimics (e.g., asphyxia, IEM, etc.) in newborns is difficult. Although methylprednisolone has been recommended in potentially life-threatening cases, the decision to continue should be reviewed on a regular basis based on the patient's clinical progress.
