RESUMO
BACKGROUND: The International Society for Human and Animal Mycology (ISHAM) working group proposed recommendations for managing allergic bronchopulmonary aspergillosis (ABPA) a decade ago. There is a need to update these recommendations due to advances in diagnostics and therapeutics. METHODS: An international expert group was convened to develop guidelines for managing ABPA (caused by Aspergillus spp.) and allergic bronchopulmonary mycosis (ABPM; caused by fungi other than Aspergillus spp.) in adults and children using a modified Delphi method (two online rounds and one in-person meeting). We defined consensus as ≥70% agreement or disagreement. The terms "recommend" and "suggest" are used when the consensus was ≥70% and <70%, respectively. RESULTS: We recommend screening for A. fumigatus sensitisation using fungus-specific IgE in all newly diagnosed asthmatic adults at tertiary care but only difficult-to-treat asthmatic children. We recommend diagnosing ABPA in those with predisposing conditions or compatible clinico-radiological presentation, with a mandatory demonstration of fungal sensitisation and serum total IgE ≥500â IU·mL-1 and two of the following: fungal-specific IgG, peripheral blood eosinophilia or suggestive imaging. ABPM is considered in those with an ABPA-like presentation but normal A. fumigatus-IgE. Additionally, diagnosing ABPM requires repeated growth of the causative fungus from sputum. We do not routinely recommend treating asymptomatic ABPA patients. We recommend oral prednisolone or itraconazole monotherapy for treating acute ABPA (newly diagnosed or exacerbation), with prednisolone and itraconazole combination only for treating recurrent ABPA exacerbations. We have devised an objective multidimensional criterion to assess treatment response. CONCLUSION: We have framed consensus guidelines for diagnosing, classifying and treating ABPA/M for patient care and research.

Data are limited on the genetic profile of primary ciliary dyskinesia (PCD) from developing countries. Here, we report one of the first study on genetic profile of patients with suspected PCD from India. In this prospective cross-sectional study, we enrolled 162 children with suspected PCD. We recorded clinical features, relevant laboratory tests for PCD and performed whole exome sequencing (WES). We are reporting 67 patients here who had positive variant/s on WES. We had 117 variants in 40 genes among 67 patients. Among the 108 unique variants, 33 were categorized as pathogenic or likely pathogenic (P/LP). We had nine novel variants in out cohort. The 29 definite PCD cases, diagnosed by composite reference standards, had variants in 16 genes namely LRRC6/DNAAF11 (5), DNAH5 (3), CCDC39 (3), HYDIN (3), DNAH11 (2), CCDC40 (2), CCDC65 (2) and one each DNAAF3, DNAAF2, CFAP300, RPGR, CCDC103, CCDC114, SPAG1, DNAI1, and DNAH14. To conclude, we identified 108 unique variants in 40 genes among 67 patients. The common genes involved in definite cases of PCD in Indian patients were LRRC6, DNAH5, CCDC39, and HYDIN. Our findings suggest a need to develop a separate genetic panel for PCD in the Indian population.
RESUMO
OBJECTIVE: To determine if initial fluid resuscitation with balanced crystalloid (e.g., multiple electrolytes solution [MES]) or 0.9% saline adversely affects kidney function in children with septic shock. DESIGN: Parallel-group, blinded multicenter trial. SETTING: PICUs of four tertiary care centers in India from 2017 to 2020. PATIENTS: Children up to 15 years of age with septic shock. METHODS: Children were randomized to receive fluid boluses of either MES (PlasmaLyte A) or 0.9% saline at the time of identification of shock. All children were managed as per standard protocols and monitored until discharge/death. The primary outcome was new and/or progressive acute kidney injury (AKI), at any time within the first 7 days of fluid resuscitation. Key secondary outcomes included hyperchloremia, any adverse event (AE), at 24, 48, and 72 hours, and all-cause ICU mortality. INTERVENTIONS: MES solution ( n = 351) versus 0.9% saline ( n = 357) for bolus fluid resuscitation during the first 7 days. MEASUREMENTS AND MAIN RESULTS: The median age was 5 years (interquartile range, 1.3-9); 302 (43%) were girls. The relative risk (RR) for meeting the criteria for new and/or progressive AKI was 0.62 (95% CI, 0.49-0.80; p < 0.001), favoring the MES (21%) versus the saline (33%) group. The proportions of children with hyperchloremia were lower in the MES versus the saline group at 24, 48, and 72 hours. There was no difference in the ICU mortality (33% in the MES vs 34% in the saline group). There was no difference with regard to infusion-related AEs such as fever, thrombophlebitis, or fluid overload between the groups. CONCLUSIONS: Among children presenting with septic shock, fluid resuscitation with MES (balanced crystalloid) as compared with 0.9% saline resulted in a significantly lower incidence of new and/or progressive AKI during the first 7 days of hospitalization.

INTRODUCTION: Data are scarce on hs-CRP as a biomarker for airway inflammation in pediatric asthma. We aimed to examine correlation between hs-CRP and asthma control levels. METHODS: Children with physician-diagnosed asthma, ages 6-15 years, were enrolled. GINA-2016 criteria were used to assess the level of asthma control. The relationships between serum hs-CRP and each of asthma control measures (asthma control criteria, spirometry, impulse oscillometry, eosinophil counts and fractional exhaled nitric oxide (FeNO) were assessed. RESULTS: 150 asthmatic children were enrolled; 52 (35%) had well controlled asthma, 76 (51%), and 22 (14%) children had partly controlled and uncontrolled asthma, respectively. Median (IQR) values of hs-CRP were 0.47 (0.1, 1.67) mg/L in well controlled, 0.30 (0.1, 1.83) mg/L in partly controlled, and 2.74 (0.55, 3.74) mg/L in uncontrolled asthma (p = 0.029). Using receiver operator characteristic (ROC) curve analysis, area under the curve for hs-CRP (mg/L) to discriminate between uncontrolled and (controlled + partly controlled) asthma was 0.67 (95% CI 0.55, 0.80) and a cutoff 1.1 mg/L of serum hs-CRP level had a sensitivity of 68.1% with specificity of 67.97%. In two groups of hs-CRP (<3 mg/L) and hs-CRP (≥3 mg/L), high hs-CRP group had higher proportion of uncontrolled asthmatic children (p = 0.03). CONCLUSION: We observed higher serum hs-CRP values in children with uncontrolled asthma, suggesting its potential role as a biomarker of asthma control.

OBJECTIVES: To determine the discriminatory value of various impulse oscillometry (IOS) parameters, and to find the cutoff value of the appropriate parameter for identifying exercise-induced bronchoconstriction (EIB) in children with asthma. METHODS: This cross-sectional study was conducted in India from October 2016 to March 2018 in children with asthma who were 6-15 years of age. One hundred and five children were enrolled and subjected to pre-exercise IOS and spirometry followed by free running treadmill test as an exercise challenge. All children could achieve minute ventilation >17.5-21 times of FEV1 during the exercise challenge test. Then, IOS and spirometry were performed at 10 ± 2, 20 ± 2, and 30 ± 2 min post-exercise challenge. EIB was defined as reduction of FEV1 ≥10% within 30 min of exercise. For purposes of analysis, the children were grouped into two categories: "EIB Present" or "EIB Absent". RESULTS: The prevalence of EIB in our study was 20.95% (n = 22). ΔR5max percentage within 30 min post-exercise (AUC 0.74; 95% CI: 0.64, 0.84) had the best discriminating capacity among all IOS parameters for identifying EIB. A cutoff value of 14.1% increase in R5 within 30 min post-exercise was obtained for detection of EIB (sensitivity-95.45%, specificity-50.6%, PPV-33.87% and NPV-97.67%). CONCLUSIONS: A percentage change in R5 with a cutoff value of 14.1% increase post-exercise had the best discriminatory capacity among all IOS parameters for detection of EIB in children with asthma. However, low positive predictive value (PPV) with high negative predictive value (NPV) made this cutoff value more apt to rule out EIB.

Chemotherapy-induced nausea and vomiting (CINV) remain the most distressing event in patients receiving highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). This meta-analysis was conducted to evaluate the efficacy and safety of olanzapine containing regimen in preventing CINV in children on HEC and MEC. We searched PubMed, Embase, and Cochrane central register of controlled trials electronic databases to identify randomized clinical trials that compared 2 groups who either got olanzapine (olanzapine group) or placebo/no olanzapine (control group) for the prevention of CINV in children. The primary outcome was to determine the efficacy of olanzapine (complete response). The secondary outcomes were nausea control, the need for rescue medications, and adverse events of olanzapine. Three randomized clinical trials (n=394 patients) were included in this meta-analysis (olanzapine group, n=194, and placebo/control group, n=200). The pooled analysis of this meta-analysis found that olanzapine had a higher complete response in all phases of emesis in the HEC group and only in the acute phase in HEC/MEC groups compared with the control group. Olanzapine had higher nausea control in all phases of HEC but no nausea control in HEC/MEC. Olanzapine also reduced the need for rescue medications. A significant number of patients in the olanzapine group experienced somnolence (grades 1 and 2), but none of the participants discontinued the study due to side effects. In conclusion, this meta-analysis showed that olanzapine significantly prevented CINV in HEC. There was also a lesser need for rescue medications in the olanzapine group. Somnolence was higher in the olanzapine group, but it was clinically insignificant.

Background & objectives: Studies assessing the spatial and temporal association of ambient air pollution with emergency room visits of patients having acute respiratory symptoms in Delhi are lacking. Therefore, the present study explored the relationship between spatio-temporal variation of particulate matter (PM)2.5 concentrations and air quality index (AQI) with emergency room (ER) visits of patients having acute respiratory symptoms in Delhi using the geographic information system (GIS) approach. Methods: The daily number of ER visits of patients having acute respiratory symptoms (less than or equal to two weeks) was recorded from the ER of four hospitals of Delhi from March 2018 to February 2019. Daily outdoor PM2.5 concentrations and air quality index (AQI) were obtained from the Delhi Pollution Control Committee. Spatial distribution of patients with acute respiratory symptoms visiting ER, PM2.5 concentrations and AQI were mapped for three seasons of Delhi using ArcGIS software. Results: Of the 70,594 patients screened from ER, 18,063 eligible patients were enrolled in the study. Winter days had poor AQI compared to moderate and satisfactory AQI during summer and monsoon days, respectively. None of the days reported good AQI (<50). During winters, an increase in acute respiratory ER visits of patients was associated with higher PM2.5 concentrations in the highly polluted northwest region of Delhi. In contrast, a lower number of acute respiratory ER visits of patients were seen from the 'moderately polluted' south-west region of Delhi with relatively lower PM2.5 concentrations. Interpretation & conclusions: Acute respiratory ER visits of patients were related to regional PM2.5 concentrations and AQI that differed during the three seasons of Delhi. The present study provides support for identifying the hotspots and implementation of focused, intensive decentralized strategies to control ambient air pollution in worst-affected areas, in addition to the general city-wise strategies.

Monogenic lupus is a subset of lupus caused by single-gene disorders, integrating the paradoxical combination of autoimmunity and immunodeficiency. Pulmonary manifestations with recurrent pneumonia and bronchiectasis have rarely been described as the predominant presentation of juvenile lupus and may suggest an alternate differential like primary immunodeficiency, especially in early childhood. We describe a case of 10-year girl who presented with a history of recurrent pneumonia, arthritis, alopecia, and poor weight gain for the past 2 years. On examination, she had respiratory distress, bilateral diffuse crackles and arthritis of the small joints of hands. Lab investigations showed pancytopenia, low complement levels and high titers of ANA and anti-dsDNA antibodies. The patient was diagnosed with juvenile lupus. Imaging studies revealed evidence of multiple lobar collapse and consolidation with bronchiectasis. She was started on steroids, HCQ and supportive measures for bronchiectasis. The child reported relief in initial symptoms of lupus on follow-up but developed recurrent thrombocytopenia requiring IVIG and escalating the doses of oral steroids. The young age and atypical presentation prompted a screening for monogenic lupus, and clinical exome sequencing revealed a novel homozygous missense variation in exon 20 of the C4Agene with clinically reduced C4 levels, consistent with the diagnosis of C4A deficiency.

Clinical features of COVID-19 range from mild respiratory symptoms to fatal outcomes. Autopsy findings are important for understanding COVID-19-related pathophysiology and clinical manifestations. This systematic study aims to evaluate autopsy findings in paediatric cases. We searched PubMed, EMBASE, and Cochrane Database Reviews. We included studies that reported autopsy findings in children with COVID-19. A total of 11 studies (24 subjects) were included. The mean age of patients was 5.9 ± 5.7 years. Grossly, there was pericardial and pleural effusion, hepatosplenomegaly, cardiomegaly, heavy soft lung, enlarged kidney, and enlarged brain. The autopsy findings of the lungs were diffuse alveolar damage (78.3%), fibrin thrombi (43.5%), haemorrhage (30.4%), pneumonia (26%), congestion and oedema (26%), angiomatoid pattern (17.4%), and alveolar megakaryocytes (17.4%). The heart showed interstitial oedema (80%), myocardial foci of band necrosis (60%), fibrin microthrombi (60%), interstitial and perivascular inflammation (40%), and pancarditis (30%). The liver showed centrilobular congestion (60%), micro/macrovesicular steatosis (30%), and arterial/venous thrombi (20%). The kidney showed acute tubular necrosis (75%), congestion (62.5%), fibrin thrombi in glomerular capillaries (37.5%), and nephrocalcinosis, mesangial cell hyperplasia, tubular hyaline/granular casts (25% each). The spleen showed splenitis (71.4%), haemorrhage (71.4%), lymphoid hypoplasia (57.1%), and haemophagocytosis (28.6%). The brain revealed oedema (87.5%), congestion (75%), reactive microglia (62.5%), neuronal ischaemic necrosis (62.5%), meningoencephalitis (37.5%), and fibrin thrombi (25%). SARS-CoV-2 and CD68 were positive by immunohistochemistry in 85.7% and 33.3% cases, respectively. Autopsy findings of COVID-19 in children are variable in all important organs. It may help in better understanding the pathogenesis of SARS-CoV-2.

BACKGROUND: Vitamin D supplementations for asthma control had shown inconsistent results. We aimed to study efficacy and safety of vitamin D supplementation in asthmatic children who were vitamin D deficient. METHODS: This double-blind, randomized controlled trial enrolled asthmatic children of 4-12 years of age who had 25-hydroxyvitamin D [25(OH)D] levels <20 ng/mL. The participants were randomized to receive either vitamin D orally 1000 IU/d for 9 months or similar-looking placebo. The primary outcomes were the proportion of children having the Childhood Asthma Control Test (CACT) score of ≥20 at the end of the treatment and adverse effects. RESULTS: The trial included 250 children (125 in each group) with a mean age of 8.1 ± 2.3 years and 180 boys. The baseline parameters were similar between the groups, including CACT score (21.7 ± 4.2 vs 21.9 ± 3.6, vitamin D vs placebo). At the end of the study, the proportion of asthmatic children who had CACT score ≥ 20 was similar between vitamin D and placebo group (93.6% vs 92.0%, P = .625). The number of exacerbations of asthma and side effect profile was also identical between the groups. 25(OH)D levels increased significantly in the vitamin D group (18.06 ± 7.11 vs 12.03 ± 5.98 ng/mL, P < .001). The results did not change when we did subgroup analysis for children with baseline CACT score < 20 and 25(OH)D levels at the end of the study ≥20 ng/mL. CONCLUSION: Vitamin D supplementation in asthmatic children with vitamin D deficiency did not improve control of asthma.

OBJECTIVES: To assess the prevalence of gastroesophageal reflux in mechanically ventilated children using 24-hour esophageal pH-metry and its role as a risk factor for ventilator-associated pneumonia. DESIGN: Prospective cohort study. SETTING: PICU of a tertiary care hospital from North India. PATIENTS: Mechanically ventilated children 1-15 years old in PICU from July 2015 to June 2017, excluding those receiving acid suppressants, known cases of gastroesophageal reflux disease, having upper gastrointestinal bleed. INTERVENTION: Demographic details, baseline investigations, diagnosis, treatment details, and Pediatric Risk of Mortality III score were recorded at enrollment. Gastroesophageal reflux was evaluated using 24-hour esophageal pH-metry. Children were followed up for 7 days or 48 hours after extubation for development of ventilator-associated pneumonia using Centers for Disease Control and Prevention criteria. Pathologic acidic gastroesophageal reflux was defined as fall in esophageal pH less than 4 for more than 4% of total time, whereas pathologic alkaline gastroesophageal reflux as rise in esophageal pH greater than 7 for more than 17% of total time. MEASUREMENTS AND MAIN RESULTS: Sixty-one children (median [interquartile range], age 73 mo [30-132 mo]; 44 boys [72%]) were enrolled. Median Pediatric Risk of Mortality III score was 10.0 (3-16). Median duration of ventilation was 6 days (3-9 d). Pathologic gastroesophageal reflux (acidic or alkaline) was present in 47 children (77%). Twelve children (19.7%) met criteria for pathologic acidic gastroesophageal reflux, whereas 44 children (72.1%) had pathologic alkaline gastroesophageal reflux; nine children (14.7%) had both pathologic acidic and alkaline gastroesophageal reflux. Of the enrolled children, 17 (27.9 %) developed ventilator-associated pneumonia. No patient had both pathologic acidic gastroesophageal reflux and ventilator-associated pneumonia. Of 17 children who developed ventilator-associated pneumonia, 12 (70.5%) had pathologic alkaline gastroesophageal reflux as compared to 32 children (72.7%) among the 44 children who did not develop ventilator-associated pneumonia (p = 0.87). CONCLUSIONS: The current study shows high incidence of gastroesophageal reflux on 24-hour esophageal pH-metry in mechanically ventilated children with medical diagnoses. The significance of this finding and its impact on ventilator-associated pneumonia and other ventilator-associated events need to be examined in larger studies.

INTRODUCTION: There is a lack of large multicentric studies in children with COVID-19 from developing countries. We aimed to describe the clinical profile and risk factors for severe disease in children hospitalized with COVID-19 from India. METHODS: In this multicentric retrospective study, we retrieved data related to demographic details, clinical features, including the severity of disease, laboratory investigations and outcome. RESULTS: We included 402 children with a median (IQR) age of 7 (2-11) years. Fever was the most common symptom, present in 38.2% of children. About 44% had underlying comorbidity. The majority were asymptomatic (144, 35.8%) or mildly symptomatic (219, 54.5%). There were 39 (9.7%) moderate-severe cases and 13 (3.2%) deaths. The laboratory abnormalities included lymphopenia 25.4%, thrombocytopenia 22.1%, transaminitis 26.4%, low total serum protein 34.7%, low serum albumin 37.9% and low alkaline phosphatase 40%. Out of those who were tested, raised inflammatory markers were ferritin 58.9% (56/95), c-reactive protein 33.3% (41/123), procalcitonin 53.5% (46/86) and interleukin-6 (IL-6) 76%. The presence of fever, rash, vomiting, underlying comorbidity, increased total leucocyte count, thrombocytopenia, high urea, low total serum protein and raised c-reactive protein was factors associated with moderate to severe disease. CONCLUSION: Fever was the commonest symptom. We identified additional laboratory abnormalities, namely lymphopenia, low total serum protein and albumin and low alkaline phosphatase. The majority of the children were asymptomatic or mildly symptomatic. We found high urea and low total serum protein as risk factors for moderate to severe disease for the first time.

BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) may be a risk factor for poorly controlled asthma in children. The studies regarding prevalence and risk factors of ABPA in children with poorly controlled asthma are limited in number. OBJECTIVES: To determine prevalence and risk factors of ABPA and aspergillus sensitization (AS) in children with poorly controlled asthma. METHODS: In this prospective cross-sectional study from a tertiary care center in India, we enrolled asthmatic children 5-15 years of age with poorly controlled asthma. We did the following investigations: spirometry, skin prick test, serum total immunoglobulin E (IgE), aspergillus-specific IgE and immunoglobulin G, serum precipitin for Aspergillus, absolute eosinophil count, chest X-ray and high-resolution computed tomography of the chest. ABPA and AS were diagnosed as per the recently proposed criteria. RESULTS: We enrolled 106 children [boys 72 (67.9%); mean age of 10.2 ± 2.6 years] with poorly controlled asthma. The prevalence of ABPA and AS were 11.3% (95% CI, 5.2-17.5%) and 61.3% (95% CI, 52.0-70.7%), respectively. The presence of brownish sputum was significantly more in ABPA compared with non-ABPA patients (33.3 vs. 4.2%, p = 0.002). The age, gender, allergic rhinitis and gastroesophageal reflux were not significantly different in ABPA compared with non-ABPA patients. CONCLUSION: The prevalence of ABPA and AS was 11.3 and 61.3%, respectively in children with poorly controlled asthma. We could not find any risk factors for ABPA except that the presence of brownish sputum was more in children with ABPA. Spirometry parameters were not significantly different in ABPA compared with non-ABPA patients.

OBJECTIVE: To study the clinical impact of respiratory viral infection in children with cystic fibrosis (CF). DESIGN: Retrospective cohort study. SETTING: Tertiary care referral centre for CF in India. PARTICIPANTS/PATIENTS: Children with CF attending a pediatric chest clinic. METHODS: Case records of the children with CF who had a pulmonary exacerbation with documented acute respiratory viral infection between October 2013 and December 2014 (Group I) and an equal number of controls (Group II) with pulmonary exacerbation in absence of acute respiratory viral infection were reviewed. OUTCOME MEASURES: The two groups were compared for the following outcomes over a period of 12-18 months: bacterial colonization, antibiotics usage, pulmonary exacerbations, numbers of outpatient visits, hospitalization and oxygen therapy and spirometric parameters. RESULTS: In total, 46 children [23 each with viral infection (Group I) and without viral infection (Group II)] of age 7-264 months were enrolled; baseline clinical status and pulmonary function tests were comparable. Mean (SD) follow-up duration in those who had viral infection and who had no viral infection was 15.7 (7.1) and 17.5 (5.4) months, respectively. On follow-up, children with viral infection (Group I) had adverse outcome in form of greater worsening of Shwachman clinical scores, number of pulmonary exacerbations requiring antibiotic usage [4 (2.1%)] and [2.8 (1.7%)], need for intravenous antibiotics 30.4% vs. 8.7%, hospitalization rates 31.8% vs. 4.3% and mortality 30.4% vs. 4.7%, respectively. CONCLUSION: Acute viral infection in children with CF affected course of illness on follow-up, including frequent and severe pulmonary exacerbations requiring hospitalization, intravenous antibiotics, decline in CF scores and increased mortality over next 12-18 months.

Background: The role of respiratory viruses (RV) in children with cancer having febrile neutropenic episodes has not been well studied. The objectives of our study were to investigate the prevalence and clinical outcomes of Respiratory viral infection (RVI). Methods: Children with cancer and febrile neutropenia (FN) having acute respiratory infections (ARI) were considered as cases and febrile neutropenic cancer patients without ARI were considered as controls. A throat swab sample was obtained for the detection of 21-respiratory pathogens. Results: A total of 81 episodes of FN in cases and 37 episodes of FN in controls were included. Prevalence of RVI (at least 1 RV) was seen in 76.5% of cases and 48.6% of controls (p = 0.005). The mixed-respiratory viruses (co-infections of ≥2 viruses) were seen only in cases (26%) (p = 0.00). Rhinovirus (36.8%) and respiratory syncytial virus (13.6%) were the most frequently detected viruses. Median duration of fever before presentation was more in cases with RVI compared to without RVI [2 (1-5) days vs 1 (1-5) day (p = 0.012)]. The median total duration of febrile period was 4 (IQR, 3-6) days in cases with RVI and 3 (IQR, 1-4) days in cases without RVI (p = 0.005). The median duration of antibiotic days were longer in cases with RVI as compared to patients without RVI [9 (IQR, 7-17) days vs 7 (IQR, 6-10) days (p = 0.046)] respectively. Conclusion: There was high prevalence of RVI in children with cancer and FN; more in association with ARI. The RVI were associated with prolonged febrile period and days of antibiotics therapy.

OBJECTIVES: To determine the prevalence of insulin resistance (IR), dyslipidemia and metabolic syndrome (MS) in children with asthma, aged 10 to 15 y, and to determine if these metabolic abnormalities showed an association with asthma symptom control and lung function. METHODS: A cross-sectional study was conducted at a tertiary centre in north India. Consecutive children with physician diagnosed asthma were enrolled. Asthma symptom control over previous four weeks was assessed as per Global Initiative for Asthma (GINA) recommendations. Fasting plasma glucose, serum insulin and lipid levels were estimated. Homeostasis Model Assessment- Insulin Resistance (HOMA-IR) was used as a marker of IR. Spirometry was performed for assessing lung function. RESULTS: Eighty-three children were enrolled. Median (IQR) age was 12.0 (11.0, 13.5) y and mean (SD) body mass index (BMI) Z score was -0.42 (1.0). Median (IQR) HOMA-IR was 1.65 (1.06, 2.39). Prevalence of IR was 42.3% (95% CI: 31.7-52.9%). Number of children with elevated triglycerides, total cholesterol, and low-density lipoprotein (LDL)-cholesterol was 4 (4.8%), 4 (4.8%) and 5 (6%), respectively. Sixty-seven (80.7%) children had low high-density lipoprotein (HDL)-cholesterol. Only one subject was found to have metabolic syndrome. Presence of IR and elevation in serum insulin and triglycerides were associated with poorer asthma control, independent of BMI. None of the metabolic parameters were associated with lung function, after adjusting for height. CONCLUSIONS: Among children with asthma, aged 10 to 15 y, the prevalence of IR was 42.3% (95% CI: 31.7-52.9%). Elevated serum insulin, triglycerides, and presence of IR were associated with poorer asthma control, after adjusting for BMI.

We analyzed the records of 869 children who underwent flexible bronchoscopy. We found procedural complications in 6.7% (n = 59), with severe events in 3.2% (n = 28). Age < 1 y, recurrent respiratory papillomatosis, and finding lower airway malacia on bronchoscopy were identified as independent risk factors for developing complications with adjusted odds ratio (95% CI) of [2.6 (1.3, 4.9); P = 0.004], [5.4 (1.7, 17.6); P = 0.005] and [2.1 (1.1, 4.0); P = 0.031], respectively.
RESUMO
OBJECTIVES: To evaluate the role infant pulmonary function tests (Tidal Breathing Flow Volume Loops, TBFVL) in children with airway anomalies and to correlate the TBFVL so obtained with bronchoscopy findings. METHODS: In this prospective cohort study, we enrolled children aged 0-2 years with airway anomalies and performed TBFVL and bronchoscopy. The primary outcome measure was graphic pattern of TBFVL in laryngomalacia. Secondary outcome measures were types of TBFVL results in various airway anomalies and controls. RESULTS: Out of 53 children enrolled, 28 (52.3%) had laryngomalacia. Pattern 3 (fluttering of inspiratory limb) was commonest TBFVL pattern in laryngomalacia. Among TBFVL parameters, the ratio of inspiratory time to expiratory time (Ti/Te) and tPTEF/tE was significantly high in children with isolated laryngomalacia compared to controls. At six months of follow-up, TBFVL pattern 1 (normal) became the commonest pattern. CONCLUSION: A particular type of airway anomaly may have a characteristic graphic pattern in TBFVL and TBFVL pattern may indicate improvement in airway anomalies in follow-up.
