COVID-19-associated Multisystem Inflammatory Syndrome in Children: A Multicentric Retrospective Cohort Study.

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new entity affecting a small percentage of children during the COVID-19 pandemic. MATERIALS AND METHODS: Demography, clinical, and laboratory variables of children admitted from April to September 2020 with MIS-C were studied retrospectively at eight hospitals in Delhi, India. RESULTS: We identified 120 patients [median age: 7 years (interquartile range (IQR): 4-10)] with male-to-female ratio of 2.3:1. Overall, 73 out of 120 children (60.8%) presented with shock, 63 (52.5%) required inopressor support, and 51 (43%) required respiratory support. We categorized the cohort into three observed clinical phenotypes: MIS-C with shock (n = 63), MIS-C with Kawasaki disease (KD) (n = 23), and MIS-C without shock and KD (n = 34). Atypical presentations were hypothermia, orchitis, meningoencephalitis, demyelination, polyneuropathy, pancreatitis, and appendicitis. Ninety-four percent had laboratory evidence of SARS-CoV-2 (78.3%, seropositive and 15.8%, RT-PCR positive). The median C-reactive protein (CRP) was 136 mg/L (IQR, 63.5-212.5) and ferritin was 543 ng/mL (IQR, 225-1,127). More than 90% received immunomodulatory therapy (intravenous immunoglobulins and/or steroids) with an excellent outcome (96% survived). CRP and absolute neutrophil count (ANC) were correlated statistically with severity. CONCLUSION: MIS-C data from Delhi are presented. Rising CRP and ANC predict the severe MIS-C.

Long-term Outcome of Children with Recurrent Abdominal Pain.

We report on long-term follow-up [mean (SD) duration, 44.7 (4.3) mo] of 48 out of 132 children with recurrent abdominal pain, who were a part of an earlier study at our hospital. 31 (64.5%) children still experienced pain; 26 (54.1%) reported their pain to be better than before, 4 children reported it to be same as before, and one child reported it worse than before. 17 out of 31 children had pain fitting into one of the categories of functional gastrointestinal disorders in the Rome III criteria; most commonly functional abdominal pain (n=6) and functional constipation (n=3). In majority of children with functional recurrent abdominal pain, pain may persist over the next 3-4 years, but shows slight improvement in frequency and severity.

Use of Transpulmonary Pressure Monitoring in the Management of Extrapulmonary Pediatric Acute Respiratory Distress Syndrome With multi organ dysfunction syndrome (MODS): Are We Peepophobic?

Manipulation of positive end-expiratory pressure (PEEP) has been shown to improve the outcome in pediatric acute respiratory distress syndrome (PARDS), but the "ideal" PEEP, in which the compliance and oxygenation are maximized, while overdistension and undesirable hemodynamic effects are minimized, is yet to be determined. Also, for a given level of PEEP, transpulmonary pressure (TPP) may vary unpredictably from patient to patient. Patients with high pleural pressure who are on conventional ventilator settings under inflation may cause hypoxemia. In such patients, raising PEEP to maintain a positive TPP might improve aeration and oxygenation without causing overdistension. We report a case of PARDS, who was managed using real-time esophageal pressure monitoring using the AVEA ventilator and thereby adjusting PEEP to maintain the positive TPP.

Etiology and Risk Factors Determining Poor Outcome of Severe Pneumonia in Under-Five Children.

OBJECTIVES: To determine the etiology of severe pneumonia (pneumonia with chest indrawing) in under-five children, and to study the risk factors for poor outcomes viz., 'treatment failure', 'need for change in antibiotics', 'prolonged hospital stay', 'need for mechanical ventilation' and 'mortality.' METHODS: Children (age 2 mo to 5 y) with pneumonia and chest drawing were enrolled prospectively from October 2012 through September 2013. Clinical history was recorded, and examination, anthropometry and investigations (including chest X-ray, blood culture and nasopharyngeal swab culture) were performed. Children were managed as per standard guidelines, and recovery outcomes were recorded in form of 'treatment failure' (defined as persistence of features of severe pneumonia after 72 h or worsening of clinical condition before 72 h), need for change of antibiotics and prolonged (>5 d) hospital stay. The associations between the clinical, anthropometric and diagnostic risk factors and the recovery outcomes were evaluated by univariate and multivariate logistic regression analysis. RESULTS: Out of 120 children enrolled in the study, 36 (42%) were culture positive (nasopharyngeal/blood); most common bacteria isolated were Streptococcal pneumoniae and Staphylococcal aureus, respectively. Treatment failure was seen in 15 (12.5%), 34 (28.3%) needed change of antibiotics, and 50 (41.6%) children required prolonged hospitalization. Low birth weight, overcrowding, general danger signs (lethargy/unable to drink), clinical rickets, crepitation, leukocytosis and positive blood culture were significant risk factors for treatment failure, prolonged hospital stay and antibiotics change. On multivariate logistic regression analysis, respiratory rate of >70/min (OR 19.94, 95%CI 1.42-280.29), lethargy/unconsciousness (OR 114.2, 95%CI 3.14-4147.92), and positive blood culture (OR 15.24, 95%CI 2.53-91.67) had more chances of treatment failure. Duration of hospital stay was prolonged in those who had inability to drink (OR 3.89, CI 1.37-10.99) or abnormal chest X-ray (OR 8.45, CI 3.56-20.04). Children with rickets (OR 3.69, CI 1.14-11.96), and those with abnormal chest X-ray (OR 9.66, CI 2.62-35.53) had a higher odds of change in antibiotics. Presence of wheeze was a protective factor for treatment failure (OR 0.03, CI 0.00-0.37) and change of antibiotics (OR 0.24, CI 0.07-0.74). CONCLUSIONS: Staphylococcus aureus and Streptococcus pneumoniae are the predominant organisms causing severe pneumonia in our setting. Children with risk factors such as respiratory rate >70/min, rickets, lethargy/unconsciousness, not able to drink, abnormal chest X-ray or positive blood culture are likely to have a delayed recovery or need of change of antibiotics, whereas those with wheeze are likely to recover faster with less chances of treatment failure.
