Vitamin D deficiency in critically ill children with sepsis

BACKGROUND

Data on the prevalence of vitamin D deficiency (VDD) in critically ill children with sepsis and its association with illness severity and outcome are limited.

AIM

To investigate the prevalence of VDD in critically ill children with sepsis.

METHODS

One hundred and twenty-four critically ill children with sepsis aged 1-12 years were prospectively enrolled in a paediatric intensive care unit (PICU) in North India over a 1-year period. Demographic data, clinical signs and risk factors for VDD, Paediatric Index of Mortality III (PRISM III) score, and sequential organ failure assessment (SOFA) score were recorded. Plasma 25-hydroxy vitamin D [25(OH)D] levels were measured by ELISA within 24 hours of admission. The occurrence of septic shock, multiple organ dysfunction syndrome (MODS) and healthcare-associated infection (HCAI), need for mechanical ventilation and catecholamines, length of PICU stay and mortality were also recorded. Cases were compared with 338 apparently healthy children for baseline variables and vitamin D status.

RESULTS

Prevalence of VDD [25(OH)D level < 50 nmol/L] was higher among critically ill children with sepsis compared to healthy controls (50.8% vs 40.2%, P = 0.04). VDD was not associated with any significant difference in baseline demographic variables or risk factors for VDD. Although there was a trend toward increased PRISM III score, septic shock, MODS, HCAI, need for mechanical ventilation and catecholamines, length of PICU stay, and mortality, the difference was not statistically significant.

CONCLUSION

A high prevalence of VDD in critically ill children with sepsis was found but it was not associated with greater severity of illness or other clinical outcomes.

Cytokine Levels in Critically Ill Children With Severe Sepsis and Their Relation With the Severity of Illness and Mortality

OBJECTIVE

To study the baseline cytokine levels and their relation with the severity of illness and mortality in critically ill children with severe sepsis.

DESIGN

Subgroup analysis of a randomized, double-blind, placebo-controlled trial.

SETTING

Pediatric intensive care unit of a tertiary level teaching hospital in India.

PATIENTS

Fifty children with severe sepsis aged 3 months to 12 years.

MATERIAL AND METHODS

Blood was collected at admission for estimation of pro-inflammatory (interleukin 6 [IL-6], IL-12p70, IL-17, and tumor necrotic factor α [TNF-α]) and anti-inflammatory (IL-10 and transforming growth factor β1 [TGF-β1]) cytokines.

PRIMARY OUTCOME

To find out correlation between cytokine levels and severity of illness scores (Pediatric Risk of Mortality [PRISM] III score, Sequential Organ Failure Assessment [SOFA], and Vasoactive-Inotropic Score [VIS]).

SECONDARY OUTCOMES

To compare cytokine levels among survivors and nonsurvivors.

RESULTS

Baseline pro-inflammatory cytokine levels (median [interquartile range]) were IL-6: 189 (35-285) pg/mL, IL-12p: 48 (28-98) pg/mL, IL-17: 240 (133-345) pg/mL, and TNF-α: 296 (198-430) pg/mL; anti-inflammatory cytokine levels were IL-10: 185 (62-395) pg/mL and TGF-β1: 204 (92-290) ng/mL. Pro-inflammatory cytokines showed positive correlation with PRISM III score: IL-6 (Spearman correlation coefficient, ρ = 0.273, P = .06), IL-12 (ρ = 0.367, P = .01), IL-17 (ρ = 0.197, P = .17), and TNF-α (ρ = 0.284, P = .05), and anti-inflammatory cytokines showed negative correlation: IL-10 (ρ = -0.257, P = .09) and TGF-β (ρ = -0.238, P = .11). Both SOFA and VIS also showed weak positive correlation with IL-12 (ρ = 0.32, P = .03 and ρ = 0.31, P = .03, respectively). Among nonsurvivors (n = 5), the levels of all the measured pro-inflammatory cytokines were significantly higher as compared to survivors, IL-6: 359 (251-499) pg/mL versus 157 (97-223) pg/mL, P < .0001, IL-12p70: 167 (133-196) pg/mL versus 66 (30-100) pg/mL, P < .0001, IL-17: 400 (333-563) pg/mL versus 237 (122-318) pg/mL, P = .009, and TNF-α: 409 (355-503) pg/mL versus 330 (198-415) pg/mL, P = .002, respectively.

CONCLUSION

In critically ill children with severe sepsis, pro-inflammatory cytokines (especially IL-12p70) showed a weak positive correlation with severity of illness and were significantly higher among nonsurvivors.

Prevalence of vitamin D deficiency in apparently healthy children in north India

BACKGROUND

The data on the prevalence of vitamin D deficiency (VDD) in apparently healthy children from India is limited.

OBJECTIVE

To assess the prevalence of VDD in apparently healthy children.

DESIGN

Prospective study.

SETTING AND SUBJECTS

Apparently healthy children from the age groups of 3 months-12 years, from the upper socioeconomical status (USES), attending the outpatient department (OPD) of a private pediatric hospital in Chandigarh, India, for minor ailments were enrolled over a period of 6 months (March-August 2013).

METHODS

Plasma levels of 25-hydroxyvitamin D [25(OH)D] were measured by competitive electrochemiluminescence immunoassay.

RESULTS

In total, 338 children (188 boys, 150 girls) with mean age of 3.31 years were enrolled. The percentages of children with deficient, insufficient, and sufficient levels of 25(OH)D were 40.24%, 25.44%, and 34.32%, respectively. Clinical signs of VDD were seen in only 8.53% of the children. The mean (±SD) levels of 25(OH)D were 27.48 (15.99) ng/mL. On univariate analysis, deficient levels of 25(OH)D were associated with relatively younger age group, female sex, failure to thrive, exclusive breastfeeding, inadequate sun exposure, and no vitamin D supplements.

CONCLUSION

A high prevalence of clinical and biochemical VDD was noted in apparently healthy children belonging to the USES.

Clinical Profile, Hospital Course and Outcome of Children with COVID-19

OBJECTIVES

To describe the epidemiological and clinical characteristics and outcome of hospitalized children with COVID-19 during the initial phase of the pandemic.

METHODS

This was a cross-sectional descriptive study conducted at the dedicated COVID-19 hospital of a tertiary care referral center in North India. Consecutive children aged 14 y or younger who tested positive for SARS-CoV-2 by RT-PCR from nasopharyngeal swab between 1 April 2020 and 15 July 2020 were included.

RESULTS

Of 31 children with median (IQR) age of 33 (9-96) mo, 9 (29%) were infants. About 74% (n = 23) had history of household contact. Comorbidities were noted in 6 (19%) children. More than half (58%) were asymptomatic. Of 13 symptomatic children, median (IQR) duration of symptoms was 2 (1-5.5) d. Fever (32%) was most common followed by cough (19%), rapid breathing (13%), diarrhea (10%) and vomiting (10%). Severe [n = 4, 13%] and critical [n = 1, 3%] illnesses were noted more commonly in infants with comorbidities. Three (10%) children required PICU admission and invasive ventilation; one died. Median (IQR) length of hospital stay was 15 (11-20) d. Follow up RT-PCR before discharge was performed in 17 children and the median (IQR) duration to RT-PCR negativity was 16 (12-19) d.

CONCLUSIONS

In the early pandemic, most children with COVID-19 had a household contact and presented with asymptomatic or mild illness. Severe and critical illness were observed in young infants and those with comorbidities.

Severe Dengue and Associated Hemophagocytic Lymphohistiocytosis in PICU

OBJECTIVES

To study the clinico-laboratory profile and outcome of children with severe dengue and dengue-associated hemophagocytic lymphohistiocytosis (HLH).

METHODS

In this retrospective study, 22 children with laboratory confirmed severe dengue admitted to pediatric intensive care unit (PICU) were enrolled. Clinical features, laboratory parameters, and outcome were noted and compared between cases fulfilling HLH-2004 criteria and those without HLH.

RESULTS

Median (IQR) age was 8 (5-10.3) y. Fever was present for mean (SD) duration of 5.3 (2.1) d. Vomiting, respiratory distress, pain abdomen and hepatomegaly were other clinical features. Thrombocytopenia, anemia and elevated serum transaminases were noted in 91%, 41% and 30% respectively; coagulopathy and hypoalbuminemia were seen in 36% each. Half (n = 11, 50%) had dengue shock syndrome. Acute respiratory distress syndrome (ARDS) (n = 7, 32%) and acute kidney injury (AKI) (n = 6, 28%) were other major organ dysfunctions. Mean (SD) duration of PICU stay was 3.6 (1.5) d with 13.6% mortality. HLH was noted in 7 (32%) cases at a median (IQR) hospital stay of 5 (2-8) d. Children with HLH had significantly higher Pediatric Index of Mortality 2 (PIM 2) score at admission and higher frequency of pain abdomen, anemia, hypoalbuminemia, elevated alanine aminotransferase (ALT) and ARDS. Length of PICU stay (5.1 vs. 2.9 d) and mortality (28.6% vs. 6.7%) were higher in HLH group, however the difference was not statistically significant. Steroids were used in 4 cases with HLH and all survived, whereas among 3 who did not receive steroids, 2 died (p = 0.23).

CONCLUSIONS

Severe dengue presents with life-threatening organ dysfunctions. HLH is increasingly recognized in dengue infection and maybe considered as a differential diagnosis in children with lower hemoglobin, hypoalbuminemia, elevated ALT and severe organ dysfunction.

Novel Coronavirus 2019 (2019-nCoV) Infection: Part I - Preparedness and Management in the Pediatric Intensive Care Unit in Resource-limited Settings

First reported in China, the 2019 novel coronavirus has been spreading across the globe. Till 26 March, 2020, 416,686 cases have been diagnosed and 18,589 have died the world over. The coronavirus disease mainly starts with a respiratory illness and about 5-16% require intensive care management for acute respiratory distress syndrome (ARDS) and multi-organ dysfunction. Children account for about 1-2% of the total cases, and 6% of these fall under severe or critical category requiring pediatric intensive care unit (PICU) care. Diagnosis involves a combination of clinical and epidemiological features with laboratory confirmation. Preparedness strategies for managing this pandemic are the need of the hour, and involve setting up cohort ICUs with isolation rooms. Re-allocation of resources in managing this crisis involves careful planning, halting elective surgeries and training of healthcare workers. Strict adherence to infection control like personal protective equipment and disinfection is the key to contain the disease transmission. Although many therapies have been tried in various regions, there is a lack of strong evidence to recommend anti-virals or immunomodulatory drugs.

Proteus syndrome: Clinical profile of six patients and review of literature

OBJECTIVE:

Proteus syndrome (PS) is characterized by patchy or segmental overgrowth and hyperplasia of multiple tissues and organs, along with susceptibility to development of tumors. Very few cases are reported in literature from developing countries. Due to certain overlapping features with other overgrowth syndromes, diagnosis is usually delayed. Our aim was to describe clinical profile of this rare condition in six patients.

MATERIALS AND METHODS:

Retrospective case sheet review of patients followed in a Pediatric Genetic and Metabolic clinic at a tertiary care institute of North India with a diagnosis of hemihypertrophy/overgrowth syndrome.

RESULTS:

Six cases presented with asymmetric overgrowth and peculiar features suggestive of PS were included in this study. Age at presentation was 2 months to 10 years; two were males and four were females. Hemihypertrophy was noticed in only one case at birth, and focal overgrowths in rest of other patients were seen later during childhood.

CONCLUSION:

Due to certain overlapping features with other overgrowth syndromes, diagnosis of PS is usually delayed. Pediatricians are the first persons who come across such patients and they should be aware about this rare condition.

Acinetobacter Sepsis Among Out-born Neonates Admitted to Neonatal Unit in Pediatric Emergency of a Tertiary Care Hospital in North India

OBJECTIVES

To study the clinical profile, complications, antibiotic resistance pattern, treatment, and outcome of out-born neonates with Acinetobacter spp. sepsis admitted in Pediatric emergency of a tertiary care hospital in North India.

METHODS

In this subgroup analysis of a prospective study (conducted over 1 y, February 2018 through January 2019), neonates with Acinetobacter spp. sepsis were included. The data collection included demographic details, clinical features, pre-referral treatment, complications, antibiotic resistance pattern, treatment, and final outcome.

RESULTS

Acinetobacter spp. accounted for 10.6% (43/406) of all isolates and 22.7% (43/189) of Gram-negative isolates. The median (IQR) age at presentation was 1 (1-2) d, 2/3rd were male, and 46.5% were preterm. All were admitted in peripheral hospitals before referral to authors' centre and all received intravenous antibiotics and fluids. The resistance to different antibiotics was: Ciprofloxacin 82%, cephalosporins 78-100%, amikacin 75%, pipercillin-tazobactum 62%, carbapenems 50-85%, chloramphenicol 83%, and tetracycline 50-60%. All isolates were sensitive to colistin. The survival rate was 37.2% (n = 16) and 62.8% (n = 27) had poor outcome [death and Left against medical advice (LAMA)]. Higher proportion of neonates with Acinetobacter sepsis had septic shock, multi-organ dysfunctional syndrome (MODS), and disseminated intravascular coagulation (DIC); and higher proportion required mechanical ventilation, vasoactive drugs, and had poor outcome compared to those with sepsis due to other organisms.

CONCLUSIONS

Acinetobacter spp. accounts for high burden of sepsis among out-born neonates and is associated with alarmingly high resistance to cephalosporins, fluroquinolones, aminoglycosides, pipercillin-tazobactum, tetracyclines, and carbapenems. Neonates with Acinetobacter spp. sepsis had higher rates of complications, requirement of mechanical ventilation and vasoactive drugs, and poor survival.

Updated Management Protocol for Multisystem Inflammatory Syndrome in Children (MIS-C)

The multisystem inflammatory syndrome in children (MIS-C) is a post-viral immunological or hyper-inflammatory complication of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection commonly seen in older children, who commonly present with fever, multi-systemic involvement including myocardial dysfunction and shock, and hyper-inflammation. The treatment of MIS-C is adapted from the treatment of other immunological or hyper-inflammatory conditions and these treatment protocols are not uniform across the globe, and more so, in India. We propose a uniform management protocol for MIS-C based on our experience of treating MIS-C cases, available evidence till now, and recent guidelines. The aims are to identify children with MIS-C with high sensitivity, recognize other infections or inflammatory processes, stratify treatment based on severity, and manage hyper-inflammatory syndrome.

Acral Gangrene: Ugly Cousin of "COVID Toes" in Multisystem Inflammatory Syndrome in Children Associated with SARS-CoV-2?

A spectrum of dermatologic manifestations has been reported in multisystem inflammatory syndrome in children associated with SARS-CoV-2 infection. We report 2 patients with multisystem inflammatory syndrome in children and severe cardiovascular dysfunction who developed acral gangrene. Both responded well to therapy and recovered in the follow-up.

Nasotracheal vs. Orotracheal Intubation and Post-extubation Airway Obstruction in Critically Ill Children: An Open-Label Randomized Controlled Trial

Background: The data on long-term nasotracheal intubation among mechanically ventilated critically ill children is limited. The purpose of this study was to compare the rate of post-extubation airway obstruction (PEAO) with nasotracheal and orotracheal intubation. Methods: This open-label randomized controlled trial was conducted in PICU of a tertiary care and teaching hospital in North India from January-December 2020 involving intubated children aged 3 months-12 years. After written informed consent, children were randomized into nasotracheal and orotracheal intubation groups. Post-extubation, modified Westley's croup score (mWCS) was used at 10-timepoints (0-min, 30 min, 1, 2, 3, 6, 12, 24, 36, and 48-h after extubation) to monitor for PEAO. The primary outcome was the rate of PEAO; and secondary outcomes were time taken for intubation, number of intubation attempts, complications during intubation, unplanned extubation, repeated intubations, tube malposition/displacement, endotracheal tube blockade, ventilator associated pneumonia, skin trauma, extubation failure/re-intubation, duration of PICU stay, and mortality. Results: Seventy children were randomized into nasotracheal (n = 30) and orotracheal (n = 40) groups. Both the groups were similar in baseline characteristics. The rate of PEAO was similar between nasotracheal and orotracheal groups (10 vs. 20%, p = 0.14). The maximum mWCS and mWCS at 10-timepoints were similar in two groups. The time taken for intubation was significantly longer (85 vs. 48 s, p < 0.001) in nasotracheal group, whereas other secondary outcomes were similar in two groups. Conclusion: The rate of PEAO was not different between nasotracheal and orotracheal groups. Clinical Trial Registration:http://ctri.nic.in, Identifier: CTRI/2020/01/022988.

Multisystem Inflammatory Syndrome in Children: Follow-Up of a Cohort from North India

Multisystem inflammatory syndrome in children (MIC-S) is a hyperinflammatory manifestation of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Information on the long-term outcome of MIS-C is limited. This study was conducted to describe the long-term outcome of MIS-C from a tertiary care center in North India. Children admitted with MIS-C from September 2020 to January 2021 were followed up after discharge until June 2021. The details during the acute phase (clinical features, investigations, treatment, and outcome) and follow-up (symptoms, echocardiographic findings, ongoing treatment, and outcome) were collected retrospectively. During the acute phase, 40 children presented at median (interquartile range [IQR]) age of 7 (5-10) years with fever, mucocutaneous, gastrointestinal, and respiratory symptoms. The majority (66.7%) of the children had positive SARS-CoV-2 serology and elevated inflammatory markers (C-reactive protein, procalcitonin, ferritin, D-dimer, and fibrinogen), lymphopenia, and thrombocytopenia. Eighty percent had shock, 72.5% had myocardial dysfunction (left ventricular ejection fraction <55%), and 22.5% had coronary artery dilatation or aneurysm. Treatment included pediatric intensive care unit admission (85%), intravenous immunoglobulin (100%), steroids (85%), aspirin (80%), vasoactive drugs (72.5%), and invasive mechanical ventilation (22.5%). Two (5%) children died because of refractory shock. Thirty-four children were followed up with until a median (IQR) of 5 (3-6) months. During the follow-up, a majority were asymptomatic, myocardial function returned to normal in all, and only one had coronary artery aneurysm. Prednisolone and aspirin were given for a median (IQR) of 3 (2-4) weeks and 4 (4-6) weeks after discharge, respectively. There was one readmission and no death during the follow-up. To conclude, the long-term outcome of MIS-C is generally favorable with resolution of cardiovascular manifestations (myocardial dysfunction and coronary artery changes) in the majority of children during follow-up.

Impact of Recent SARS-CoV-2 Infection on the Course and Severity of Dengue in Children: A Prospective Observational Study from North India

In 2020, a considerable overlap occurred between the COVID-19 pandemic and seasonal dengue transmission in India. This study aimed to evaluate the effects of acute or recent infection with SARS-CoV-2 on the course and outcomes of dengue fever in children. We prospectively enrolled 44 children with a clinical and laboratory diagnosis of dengue fever. Assessment of acute and recent SARS-CoV-2 infection was done using reverse transcription-polymerase chain reaction and IgG antibody through ELISA. Children were grouped based on evidence of SARS-CoV-2 exposure and clinical severity, and outcomes were compared. The median age of the study cohort was 96 months (interquartile range [IQR]: 69-129 months). Fever (98%), vomiting (78%), abdominal pain (68%), hepatomegaly (68%), and edema (32%) were the common features. About two-thirds (N = 30) had severe dengue; 20 (45%) had dengue shock. Liver dysfunction (58%) and acute kidney injury (25%) were other major organ dysfunctions. Nineteen (43%) children stayed in the pediatric intensive care unit for a median duration of 5 days (IQR: 2-11 days). None had acute SARS-CoV2 infection; however, IgG against SARS-CoV-2 was detected in 15 (34%) cases. Children with recent exposure to SARS-CoV-2 showed a trend toward a lower incidence of acute kidney injury, fewer organ dysfunctions, and a lower frequency of invasive ventilation. Four children (9%) died; none of the deaths were in the SARS-CoV-2-exposed group. The present study exposes preliminary evidence that dengue fever might follow a less severe course in children with recent exposure to SARS-CoV-2 infection. However, it is pertinent to understand the antigenic similarity and cross-protective antibody response between the two viruses and their clinical relevance.

Defect of cobalamin intracellular metabolism presenting as diabetic ketoacidosis: a rare manifestation

Hypoglycemia is the usual feature of commonly occurring organic acidemias. Organic acidemias manifesting as hyperglycemia or diabetic ketoacidosis are rare and only a few cases have been reported. We report a 13-month-old boy who presented with vomiting, dehydration, coma, hyperglycemia, high anion gap metabolic acidosis and ketosis, mimicking diabetic ketoacidosis (DKA). Treatment with parenteral fluid, electrolytes, and insulin infusion resulted in an improvement in hyperglycemia, but persistence of metabolic acidosis and lack of improvement of neurologic status led us to suspect an organic acidemia. Urinary organic acid analysis revealed increased methylmalonic acid levels. In addition, hyperhomocysteinemia and homocystinuria were also noted in presence of normal vitamin B12 levels. This confirmed the diagnosis of cobalamin metabolism defect leading to combined methylmalonic aciduria and homocystinuria. There was some improvement in neurologic status and metabolic parameters after treatment with low-protein diet, vitamin B12, folic acid, and L-carnitine, but he ultimately succumbed to polymicrobial nosocomial sepsis. The entire MMACHC gene of the patient was sequenced and no mutations were identified. This is probably the first case report of cobalamin intracellular metabolism defect (CblC/CblD/CblF/CblJ or ABCD4) presenting as diabetic ketoacidosis.

Intensive Care Needs and Short-Term Outcome of Multisystem Inflammatory Syndrome in Children (MIS-C): Experience from North India

OBJECTIVES

To describe the intensive care needs and outcome of multisystem inflammatory syndrome in children (MIS-C).

METHODOLOGY

This retrospective study was conducted in the pediatric emergency, pediatric intensive care unit (PICUs) and the coronavirus disease 2019 (COVID 19) hospital of a tertiary teaching and referral hospital in North India over a period of 5 months (September 2020 to January 2021). Clinical details, laboratory investigations, intensive care needs, treatment and short-term outcome were recorded.

RESULTS

Forty children with median interquartile range age of 7 (5-10) years were enrolled. The common clinical features were fever (97.5%), mucocutaneous involvement (80%), abdominal (72.5%) and respiratory (50%) symptoms. Shock was noted in 80% children. Most cases (85%) required PICU admission where they received nasal prong oxygen (40%), non-invasive (22.5%) and invasive (22.5%) ventilation and vasoactive drug support (72.5%). The confirmation of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) exposure was in the form of positive serology (66.7%), reverse transcriptase polymerase chain reaction (10%), and contact with SARS-CoV-2 positive case (12.5%). The common echocardiographic findings included myocardial dysfunction (ejection fraction <55%; 72.5%), and coronary artery dilatation or aneurysm (22.5%). The immunomodulatory treatment included intravenous immunoglobulin (2 g/kg) (100%) and steroids (methylprednisolone 10-30 mg/kg/day for 3-5 days) (85%). Aspirin was used in 80% and heparin (low molecular weight) in 7.5% cases. Two children died (5%) and median duration of PICU and hospital stay in survivors were 5 (2-8) and 7 (4-9) days, respectively. Children with shock showed higher total leucocyte count and higher rates of myocardial dysfunction.

CONCLUSION

Cardiovascular involvement and shock are predominant features in severe disease. Early diagnosis can be challenging given the overlapping features with other diagnoses. A high index of suspicion is warranted in children with constellation of fever, mucocutaneous, gastrointestinal and cardiovascular involvement alongwith evidence of systemic inflammation and recent or concurrent SARS-CoV-2 infection. The short-term outcome is good with appropriate organ support therapies and immunomodulation.

Recurrent Guillain-Barré Syndrome: Clinical Profile and Outcome

OBJECTIVES

To compare clinical, neurological, treatment and outcome of recurrent Guillian-Barré Syndrome (GBS) with non-recurrent GBS. Also, to compare different episodes of recurrent GBS.

METHODS

The patient's case records were retrieved retrospectively from the electronic database and case record files. Clinical profile, nerve conduction study, treatment, and outcome details of children with a diagnosis of GBS admitted in Pediatric Intensive Care Unit (PICU) from 2010 to March 2022 were screened. Recurrent GBS cases, as defined by the National Institute of Neurological and Communicative Diseases and Strokes (NINCDS) criteria, were analysed separately. The comparison was made between the first episode of recurrent GBS with non-recurrent GBS, and predictors of recurrence were identified. A comparison of course and outcome was also done between different episodes of GBS in recurrent cases.

RESULTS

Recurrent GBS was observed in 11 (4.7%) out of 234 cases during the study period. The presence of respiratory (p 0.015) and gastrointestinal illness (p 0.007) as preceding illnesses were associated with recurrence. No difference was noted between the first episode of recurrent GBS and non-recurrent GBS. The first and second episodes of GBS in 11 recurrent cases were similar in course and outcome.

CONCLUSIONS

Recurrent GBS is underreported but a known entity. No difference was seen between the two episodes of recurrent GBS. However, more data is required to find the features of recurrent GBS so that limited PICU resources can be used judiciously and intervention planned accordingly.

Post-neonatal Tetanus in a PICU of a Developing Economy: Intensive Care Needs, Outcome and Predictors of Mortality

OBJECTIVES

To evaluate pediatric intensive care unit (PICU) needs, outcome and predictors of mortality in post-neonatal tetanus.

MATERIALS AND METHODS

Review of 30 consecutive post-neonatal tetanus cases aged 1 months to 12 years admitted to a PICU in north India over a period of 10 years (January 2006 to December 2015).

RESULTS

Chronic suppurative otitis media was the commonest portal of entry. All received tetanus toxoid, human tetanus immunoglobulin (HTIG) and appropriate antibiotics; 7 (23.3%) received intrathecal HTIG. Common complications were respiratory failure, rhabdomyolysis, autonomic dysfunction, acute kidney injury and healthcare-associated infections. PICU needs were as follows: ventilation; benzodiazepine, morphine and magnesium sulfate infusion; neuromuscular blockers, inotropes, tracheostomy and renal replacement therapy. Mortality rate was 40%; severity Grade IIIb, autonomic dysfunction, use of vasoactive drugs and those who did not receive intrathecal HTIG were significantly associated with mortality.

CONCLUSION

Post-neonatal tetanus is associated with high mortality, and PICU needs include management of spasms, autonomic dysfunction and complications and cardiorespiratory support.

Clinicolaboratory Profile, Treatment, Intensive Care Needs, and Outcome of Pediatric Inflammatory Multisystem Syndrome Temporally Associated with SARS-CoV-2: A Systematic Review and Meta-analysis

This study was aimed to summarize the current data on clinicolaboratory features, treatment, intensive care needs, and outcome of pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2; PIMS-TS) or multisystem inflammatory syndrome in children (MIS-C). Articles published in PubMed, Web of Science, Scopus, Google Scholar, and novel coronavirus disease 2019 (COVID-19) research database of World Health Organization (WHO), Centers for Disease Control and Prevention (CDC) database, and Cochrane COVID-19 study register between December 1, 2019 and July 10, 2020. Observational studies involving patients <21 years with PIMS-TS or MIS-C were reported the clinicolaboratory features, treatment, intensive care needs, and outcome. The search identified 422 citations and finally 18 studies with 833 participants that were included in this study, and pooled estimate was calculated for parameters of interest utilizing random effect model. The median age was 9 (range: 8–11) years. Fever, gastrointestinal symptoms, rash, conjunctival injection, and respiratory symptoms were common clinical features. Majority (84%) had positive SARS-CoV-2 antibody test and only one-third had positive reverse transcript polymerase chain reaction (RT-PCR). The most common laboratory abnormalities noted were elevated C-reactive protein (CRP), D-dimer, procalcitonin, brain natriuretic peptide (BNP), fibrinogen, ferritin, troponin, interleukin 6 (IL-6), lymphopenia, hypoalbuminemia, and thrombocytopenia. Cardiovascular complications included shock (65%), myocardial dysfunction (61%), myocarditis (65%), and coronary artery abnormalities (39%). Three-fourths of children required admission to pediatric intensive care unit (PICU) where they received vasoactive medications (61%) and mechanical ventilation (25%). Treatment strategies used included intravenous immunoglobulin (IVIg; 82%), steroids (54%), antiplatelet drugs (64%), and anticoagulation (51%). Mortality for patients with PIMS-TS or MIS-C was low (n = 13). In this systematic review, we highlight key clinical features, laboratory findings, therapeutic strategies, intensive care needs, and observed outcomes for patients with PIMS-TS or MIS-C. Commonly observed clinical manifestations include fever, gastrointestinal symptoms, mucocutaneous findings, cardiac dysfunction, shock, and evidence of hyperinflammation. The majority of children required PICU admission, received immunomodulatory treatment, and had good outcome with low mortality.

Pediatric empyema thoracis: What has changed over a decade?

OBJECTIVES

The purposes of this paper are to study clinicobacteriological profile, treatment modalities and outcome of pediatric empyema thoracis and to identify changes over a decade.

DESIGN

This is a retrospective study.

SETTING

Department of Pediatrics of a tertiary care hospital in North India.

PATIENTS

We enrolled 205 patients (1 month-12 years) of empyema thoracis admitted over 5 years (2007-11) and compared the profile with that of a previous study from our institute (1989-98).

RESULTS

Pleural fluid cultures were positive in 40% (n = 82) cases from whom 87 isolates were obtained. Staphylococcus aureus was the most common isolate (66.7%). Methicillin-sensitive S. aureus accounted for 56%, Methicillin-resistant S. aureus (MRSA) 10% and gram-negative organisms 18.3% of isolates. Intercostal drainage tube (ICDT) was inserted in 97.5%, intrapleural streptokinase was administered in 33.6%, and decortication performed in 27.8% cases. Duration of hospital stay was 17.2 (±6.3) days, duration of antibiotic (intravenous and oral) administration was 23.8 (±7.2) days and mortality rate was 4%. In the index study (compared with a previous study), higher proportion of cases received parenteral antibiotics (51.7% vs. 23.4%) and ICDT insertion (20.5% vs. 7%) before referral and had disseminated disease (20.5% vs. 14%) and septic shock (11.2% vs. 1.6%), less culture positivity (40% vs. 48%), more MRSA (10.3% vs. 2.5%) and gram-negative organisms (18.4% vs. 11.6%), increased use of intrapleural streptokinase and surgical interventions (27.8% vs. 19.7%), shorter hospital stay (17 vs. 25 days) and higher mortality (3.9% vs. 1.6%).

CONCLUSIONS

Over a decade, an increase in the incidence of empyema caused by MRSA has been noticed, with increased use of intrapleural streptokinase and higher number of surgical interventions.

Principles of Management of Central Nervous System Infections

CNS infections in children are medical emergency and are associated with high mortality and morbidity. For diagnosis, a high index of suspicion is required. Clinical assessment should be supplemented by laboratory investigations including CSF Gram stain and cultures, blood culture, PCR on CSF, serological tests, and imaging. Commonly associated life threatening complications include coma, seizure, raised intracranial pressure (ICP), focal deficits, shock, respiratory failure, and fluid and electrolyte abnormalities. Immediate management should first address control of airway, breathing and circulation; protocolized management of raised ICP and status epilepticus; maintaining adequate intravascular volume; and close monitoring for early detection of complications. Appropriate antimicrobial agents should be administered promptly according to the suspected pathogen. Clinical evaluation, laboratory workup, specific antimicrobial therapy, supportive treatment, and management of associated complications should go hand in hand in a protocolized way for better outcome.

Status Dystonicus in a Child with Familial Idiopathic Hypoparathyroidism

Hypoparathyroidism leading to status dystonicus is rarely reported in literature. The authors present an 8-y-old girl with idiopathic familial hypoparathyroidism who presented with status dystonicus. She was managed successfully with midazolam infusion, calcium and vitamin D supplementation, and oral anti-dystonia drugs.

Microorganisms Profile and Antimicrobial Resistance Pattern in Outborn Neonates in Northern India: A Hospital-Based Observational Study

BACKGROUND

Neonates born somewhere else (outborn) and treated in a referral centre have different microbiological profile. We report the microorganism's profile and antimicrobial resistance (AMR) in blood culture proven sepsis in outborn neonates.

METHODS

Culture positive neonatal sepsis from a neonatal unit of a referral institute catering to outborn neonates was studied over an 18 months duration. Data from the hospital information system were used to analyse the culture positivity rates, the spectrum of the microorganisms isolated and AMR pattern.

RESULTS

Out of 5258 admitted neonates, 3687 blood samples were sent for suspect sepsis. The blood cultures were positive in 537 (14.6%) samples from 514 neonates. Gram-positive cocci (GPC) were the most common [240 (45%)] followed by gram-negative bacilli (GNB) [233 (43.4%)] and fungi [64 (11.9%)]. Coagulase negative staphylococcus (CONS) contributed to two-thirds of GPC followed by Klebsiella [93 (17.3%)] and Acinetobacter species [52 (9.7%)]. In 403 (75%) neonates, organisms grew in the samples sent at or within 24 h of admission. The case fatality rate was significantly higher in those with culture positive sepsis. The resistance to meropenem and imipenem was documented in 57.1% and 49.7%, respectively and 48% of the GNB was multidrug resistant.

CONCLUSIONS

CONS followed by Klebsiella species were the most common organisms isolated. Three-fourths of the neonates had organisms grown at or within 24 h from admission. More than half of the GNB were multidrug resistant. The case fatality rate was significantly higher in those with culture positive sepsis.
