RESUMEN

Immune-mediated or autoimmune encephalitis (AE) is a relatively new, rare and elusive form of encephalitis in children. We retrospectively collected seropositive children (0-18 years old) with well characterized antibodies through 3 reference laboratories in Israel. Clinical symptoms, MRI and EEG findings and treatment courses were described. A total of 16 patients were included in the study, with 10 females. Anti NMDA encephalitis was most common followed by anti HU and anti mGLuR1. Psychiatric symptoms, abnormal movements, seizures and behavioral changes were the most common presentation. Pathological MRI and EEG findings were described in 37% and 56% of children, respectively. Treatment with corticosteroids, Intravenous immunoglobulins (IVIG) was first line in most children. Following inadequate response children were treated with plasmapheresis and/or rituximab. Two patients relapsed following both first and second line protocols. In terms of long term prognosis, 9 children (56%) had one or more residual behavioral, psychiatric or neurologic findings. Three children required hospitalization for rehabilitation. AE remains a rare diagnosis with variable presenting symptoms, requiring a high index of suspicion. Consensus recommended treatment is generally effective in the pediatric population. Female gender was associated with a higher chance of severe disease. Larger cohorts would be needed to identify prognostic factors in the pediatric population.

RESUMEN

Foreign Body Aspiration (FBA) is a common medical emergency among young children, but the evaluation and management of a suspected FBA case can vary across physicians and centers. We aimed to identify which clinical, laboratory, and radiological findings can predict FBA in children and to evaluate a clinical score to improve FBA prediction. This is a retrospective cohort study of patients aged 0-18 years admitted to Soroka University Medical Center between 2010 and 2020 with suspected FBA. All patients underwent flexible bronchoscopy and were divided into positive and negative FBA groups. A newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, was evaluated for its predictability. The study included 412 children (median age 21 months, 56.8% females), of whom 154 (37.4%) had FBA and 258 (62.6%) did not. Multivariate regression analysis showed exposure to nuts/seeds, unilateral wheezing or decreased breath sounds, stridor, and suggestive findings on chest X-ray were significant risk factors for FBA (OR [95%CI] -1.994[1.290-3.082], 1.487[1.206-1.832], 1.883 [1.011-3.509] and 2.386[1.917-2.970], respectively). However, a choking episode, acute cough, and absence of fever and rhinorrhea did not predict FBA. FOBAS showed an increased risk of FBA for each additional point of the score, with an odds ratio of 1.572 (95% CI-1.389-1.799).  Conclusion: FOBAS is a good predictor for the presence of FBA in children. Once prospectively validated, FOBAS could aid in decision-making at the emergency department, enabling more standardized care, reducing unnecessary procedures, and leading to better clinical outcomes. What is Known: • The evaluation and management of a child with suspected foreign body aspiration (FBA) vary across physicians and centers, without a consensus regarding the indications and criteria for performing bronchoscopy. • Flexible bronchoscopy is the standard procedure for the diagnosis and sometimes treatment of FBA in children, but it may hold potential complications. What is New: • We propose a newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, for the prediction of FBA in children at the emergency department. • The FOBAS is a good predictor of FBA in children. The score enables more standardized care and may reduce unnecessary procedures.

RESUMEN

Chest X-ray (CXR) is an important tool in the assessment of children with suspected foreign body aspiration (FBA), although it can falsely be interpreted as normal in one-third of the cases. The aim of this study is to evaluate the positive predictive value of CXR in children hospitalized with suspected FBA, when interpreted by three disciplines: pediatric pulmonology, pediatric radiology, and pediatric residents. This is a retrospective study that included children aged 0-18 years, admitted with suspected FBA, between 2009 and 2020 in one tertiary center. All patients underwent CXR and a flexible/rigid bronchoscopy for the definitive diagnosis of FBA, up to 1 week apart. Two physicians from each discipline interpreted the CXR, independently. Intra-raters' and inter-raters' agreements were assessed. Sensitivity, specificity, and area under the curve (AUC) were calculated for each discipline. Four hundred seventy-three children were included in the study, 175 (37%) with FBA and 298 (63%) without FBA on flexible/rigid bronchoscopy. The most common radiological findings, as interpreted by a pediatric pulmonologist, were unilateral hyperinflation (47%), radiopaque FB (37.6%), lobar atelectasis (10.3%), unilateral hyperinflation with atelectasis (3.4%), and lobar consolidation (1.7%). Intra-raters' agreement ranged from 0.744 (p < 0.001) among pediatric pulmonologists to 0.326 (p < 0.001) among pediatric radiologists. AUC for predicting FBA based on a CXR was 0.81, 0.77, and 0.7 when interpreted by pediatric pulmonologists, pediatric residents, and radiologists, respectively (p < 0.001). CONCLUSIONS: CXR has a high positive predictive value and independently predicts FBA in children; however, normal CXR should not rule out FBA. Predictability is variable among different disciplines. WHAT IS KNOWN: • Chest X-ray is an important tool in the assessment of children with suspected foreign body aspiration (FBA). • Chest X-ray can be interpreted as normal in one-third of the cases. WHAT IS NEW: • Chest X-ray independently predicts FBA in children, with a high positive predictive value. • The ability of chest x-ray to predict FBA in children differs between pediatric residents, pediatric radiologists, and pediatric pulmonologists.

RESUMEN

BACKGROUND: During coronavirus disease 2019 (COVID-19) pandemic, less isolation of common winter viruses was reported in the southern hemisphere. OBJECTIVES: To evaluate annual trends in respiratory disease-related admissions in a large Israeli hospital during and before the pandemic. METHODS: A retrospective analysis of medical records from November 2020 to January 2021 (winter season) was conducted and compared to the same period in two previous years. Data included number of admissions, epidemiological and clinical presentation, and isolation of respiratory pathogens. RESULTS: There were 1488 respiratory hospitalizations (58% males): 632 in 2018-2019, 701 in 2019-2020, and 155 in 2020-2021. Daily admissions decreased significantly from a median value of 6 (interquartile range [IQR] 4-9) and 7 per day (IQR 6-10) for 2018-2019 and 2019-2020, respectively, to only 1 per day (IQR 1-3) in 2020-2021 (P-value < 0.001). The incidence of all respiratory viruses decreased significantly during the COVID-19 pandemic, with no hospitalizations due to influenza and only one with respiratory syncytial virus. There was also a significant decline in respiratory viral and bacterial co-infections during the pandemic (P-value < 0.001). CONCLUSIONS: There was a significant decline in pediatric respiratory admission rates during the COVID-19 pandemic. Possible etiologies include epidemiological factors such as mask wearing and social distancing, in addition to biological factors such as viral interference. A herd protection effect of adults and older children wearing masks may also have had an impact.

RESUMEN

BACKGROUND: Children with Down syndrome (DS) often undergo flexible bronchoscopies (FB) due to common respiratory symptoms. OBJECTIVE: To examine the indications, findings, and complications of FB in pediatric DS patients. METHODS: A retrospective case-control study on FB performed in DS pediatric patients between 2004 and 2021 in a tertiary center. DS patients were matched to controls (1:3) based on age, gender, and ethnicity. Data collected included demographics, comorbidities, indications, findings, and complications. RESULTS: Fifty DS patients (median age 1.36 years, 56% males) and 150 controls (median age 1.27 years, 56% males), were included. Evaluation for obstructive sleep apnea and oxygen dependence were more common indications among DS (38% vs. 8%, 22% vs. 4%, p < 0.01, respectively). Normal bronchoscopy was less frequent in DS compared with controls (8% vs. 28%, p = 0.01). Soft palate incompetence and tracheal bronchus were more frequent in DS (12% vs. 3.3%, p = 0.024, 8% vs. 0.7%, p = 0.02, respectively). Complications were more frequent in DS (22% vs. 9.3%, incidence rate ratio [IRR] 2.36, p = 0.028). In DS, cardiac anomalies (IRR 3.96, p < 0.01), pulmonary hypertension (IRR 3.76, p = 0.006), and pediatric intensive care unit (PICU) hospitalization before the procedure (IRR 4.2, p < 0.001) were associated with higher complication rates. In a multivariate regression model, history of cardiac disease and PICU hospitalization before the procedure, but not DS, were independent risk factors for complications with an IRR of 4 and 3.1, respectively (p = 0.006, p = 0.05). CONCLUSION: DS pediatric patients undergoing FB are a unique population with specific indications and findings. DS pediatric patients with cardiac anomalies and pulmonary hypertension are at the highest risk for complications.

RESUMEN

OBJECTIVES: To identify predictors of a severe clinical course of multisystem inflammatory syndrome in children (MIS-C), as defined by the need for inotropic support. METHODS: This retrospective study included patients diagnosed with MIS-C (according to the CDC definition) in nine Israeli and one US medical centre between July 2020 and March 2021. Univariate and multivariate regression models assessed odds ratio (OR) of demographic, clinical, laboratory and imaging variables during admission and hospitalization for severe disease. RESULTS: Of 100 patients, 61 (61%) were male; mean age 9.65 (4.48) years. Sixty-five patients were hypotensive, 44 required inotropic support. Eleven patients with MIS-C fulfilled Kawasaki disease diagnostic criteria; 87 had gastrointestinal symptoms on admission. Echocardiographic evaluation showed 10 patients with acute coronary ectasia or aneurysm, and 37 with left ventricular dysfunction. In a univariate model, left ventricular dysfunction was associated with severe disease [OR 4.178 (95% CI 1.760, 9.917)], while conjunctivitis [OR 0.403 (95% CI 0.173, 0.938)] and mucosal changes [OR 0.333 (95% CI 0.119, 0.931)] at admission were protective. Laboratory markers for a severe disease course were low values of haemoglobin, platelets, albumin and potassium; and high leukocytes, neutrophils, troponin and brain natriuretic peptide. In multivariate analysis, central nervous system involvement and fever >39.5°C were associated with severe disease. Mucosal involvement showed 6.2-fold lower risk for severe disease. Low haemoglobin and platelet count, and elevated C-reactive protein and troponin levels were identified as risk factors for severe disease. CONCLUSION: Key clinical and laboratory parameters of MIS-C were identified as risk factors for severe disease, predominantly during the disease course and not at the time of admission; and may prompt close monitoring, and earlier, more aggressive treatment decisions. Patients presenting with a Kawasaki-like phenotype were less likely to require inotropic support.

RESUMEN

Introduction: We aimed to assess the clinical significance of M1-MCA occlusion with visualization of both MCA-M2 segments ["Tilted-V sign" (TVS)] on initial CT angiography (CTA) in patients with acute ischemic stroke (AIS) undergoing endovascular thrombectomy (EVT). Methods: Data for patients with consecutive AIS undergoing EVT for large vessel occlusion (LVO) in two academic centers are recorded in ongoing databases. Patients who underwent EVT for M1-MCA occlusions ≤ 6 h from symptom onset were included in this retrospective analysis. Results: A total of 346 patients met the inclusion criteria; 189 (55%) had positive TVS. Patients with positive TVS were younger (68 ± 14 vs. 71 ± 14 years, P = 0.028), with similar rates of vascular risk factors and baseline modified Rankin scores (mRS) 0-2. The rates of achieving thrombolysis in cerebral ischemia (TICI) 2b-3 were similar to the two groups (79%), although successful first-pass recanalization was more common with TVS (64 vs. 36%, p = 0.01). On multivariate analysis, higher collateral score [odds ratio (OR) 1.38 per unit increase, p = 0.008] and lower age (OR 0.98 per year increase, p = 0.046) were significant predictors of TVS. Patients with positive TVS had higher post-procedural Alberta Stroke Program Early CT Score (ASPECTS; 6.9 ± 2.2 vs. 5.2 ± 2.3, p = 0.001), were discharged with lower National Institutes of Health Stroke Score (NIHSS; 6±6 vs. 9±7, p = 0.003) and higher rates of mRS 0-2 (29.5 vs. 12%, p = 0.001), and had lower rates of 90-day mortality (13.2 vs. 21.6%, p = 0.038). However, TVS was not an independent predictor of functional independence (OR 2.51; 95% CI 0.7-8.3). Conclusion: Tilted-V Sign, an easily identifiable radiological marker, is associated with fewer recanalization attempts, better functional outcomes, and reduced mortality.

RESUMEN

BACKGROUND: Inhaled bronchodilators are frequently used among patients with primary ciliary dyskinesia (PCD), although neither the effectiveness nor the prevalence of their use is known, due to the paucity of relevant studies. METHODS: This is a retrospective analysis of pre- and post-bronchodilator spirometry results, of patients with PCD from two centers. Correlations were examined of bronchodilator response, with asthma and atopy markers. RESULTS: Of 115 patients, 46 (40%) completed spirometry pre- and post-bronchodilation. Of these, 26 (56.5%) demonstrated reversible airway obstruction (increase in %FEV1 predicted ≥ 10%). Obstruction reversibility was not found to be associated with a family history of asthma, blood eosinophil level, elevated IgE, or atopy symptoms. Of the 46 patients who completed bronchodilator spirometry, 29 (63%) were regularly using bronchodilators and inhaled corticosteroids. CONCLUSIONS: More than half of patients with PCD presented with reversible airway obstruction, without any correlation to markers of personal or familial atopy. Inhaled bronchodilators and corticosteroid therapies are commonly used for treating PCD. Evaluating bronchodilator response should be considered, and its effectiveness should be further studied.

RESUMEN

INTRODUCTION: Since the development of COVID-19 vaccines, more than 4.8 billion people have been immunized worldwide. Soon after vaccinations were initiated, reports on cases of myocarditis following the second vaccine dose emerged. This study aimed to report our experience with adolescent and young adults who developed post-COVID-19 vaccine myocarditis and to compare these patients to a cohort of patients who acquired pediatric inflammatory multisystem syndrome (PIMS/PIMS-TS) post-COVID-19 infection. METHODS: We collected reported cases of patients who developed myocarditis following COVID-19 vaccination (Pfizer mRNA BNT162b2) from all pediatric rheumatology centers in Israel and compared them to a cohort of patients with PIMS. RESULTS: Nine patients with post-vaccination myocarditis were identified and compared to 78 patients diagnosed with PIMS. All patients with post-vaccination myocarditis were males who developed symptoms following their second dose of the vaccine. Patients with post-vaccination myocarditis had a shorter duration of stay in the hospital (mean 4.4 ± 1.9 vs. 8.7 ± 4.7 days) and less myocardial dysfunction (11.1% vs. 61.5%), and all had excellent outcomes as compared to the chronic changes among 9.2% of the patients with PIMS. CONCLUSION: The clinical course of vaccine-associated myocarditis appears favorable, with resolution of the symptoms in all the patients in our cohort.

RESUMEN

BACKGROUND: 25(OH) vitamin D levels are inversely associated with respiratory infections and childhood wheezing. OBJECTIVE: To evaluate serum 25(OH) vitamin D levels in infants and toddlers with acute bronchiolitis, compared to subjects with non-respiratory febrile illness. METHODS: A prospective cross-sectional case-control study which compared serum 25(OH) vitamin D levels between infants and toddlers diagnosed with acute bronchiolitis to subjects with non-respiratory febrile illness. Multivariate logistic regression, adjusted for age, sex, ethnicity and nutrition was performed. Correlation between serum vitamin D levels and bronchiolitis severity was assessed via Modified Tal Score and length of hospital stay (LOS). RESULTS: One hundred twenty-seven patients aged < 24 months were recruited; 80 diagnosed with acute bronchiolitis and 47 patients with non- respiratory febrile illnesses. Both groups had similar demographics aside from age (median [IQR] 5 [3-9] vs. 9 [5-16] months in the bronchiolitis group compared to control group (p = 0.002)). Serum 25(OH) vitamin D levels were significantly lower in the bronchiolitis group; median [IQR] 28[18-52] vs. 50[25-79] nmol/L, respectively, (p = 0.005). Deficient vitamin D levels (< 50 nmol/L) was found more frequently in the bronchiolitis group than controls; 73% vs. 51% (p = 0.028). Multivariate logistic regression showed vitamin D deficiency was more probable in bronchiolitis patients; OR [95% CI] 3.139[1.369-7.195]. No correlation was found between serum vitamin D levels and bronchiolitis severity, which was assessed via Modified Tal Score and by length of hospital stay. CONCLUSION: Children with acute bronchiolitis displayed significantly lower vitamin D levels than children with non-respiratory acute febrile illnesses.

RESUMEN

BACKGROUND: Prescription drug monitoring programs (PDMPs) exist in 49 states to guide opioid prescribing. In 40 states, clinicians must check the PDMP prior to prescribing an opioid. Data on mandated PDMP checks show mixed results on opioid prescribing. OBJECTIVES: This study sought to examine the impact of the Massachusetts mandatory PDMP check on opioid prescribing for discharges from an urban tertiary emergency department (ED). METHODS: This was a retrospective cohort study of discharges from one ED from 7/1/2010-10/15/2018. The primary outcome was the monthly percentage of patients discharged from the ED with an opioid prescription. The intervention was Massachusetts mandating a PDMP check for all opioid prescriptions. Prescribing was compared pre- and post-mandate. Interrupted time series (ITS) analysis accounted for known declining trends in opioid prescribing. RESULTS: Of 273,512 ED discharges, 35,050 (12.8%) received opioid prescriptions. Mean monthly opioid prescribing decreased post-intervention from 15.1% (SD ± 3.5%) to 5.1% (SD ± 0.9%; p < 0.001). ITS showed equal pre and post-intervention slopes (-0.002, p = 0.819). A small immediate decrease occurred in prescribing around the mandated check: a 3-month level effect decrease of 0.018 (p = 0.039), 6-month level effect 0.019 (p = 0.023), and a 12-month level effect of 0.020 (p = 0.019). The 24-month level effect was not decreased. CONCLUSION: Prior to the mandated PDMP check, ED opioid prescribing was declining. The mandate did not change the rate of decline but was associated with a non-sustained drop in opioid prescribing immediately following enactment.

RESUMEN

AIM: We examined the impact of the COVID-19 pandemic on how many children were admitted to Israel's largest tertiary paediatric hospital and why they were admitted. METHODS: Israel declared COVID-19 a national emergency on 19 March 2020. This study examined daily hospital admissions to our three general paediatric wards during the COVID-19 lockdown period from 20 March to 18 April 2020. These 258 admissions were compared with the 4217 admissions from the period immediately before this, 1 February to 19 March 2020, plus 1 February to 18 April in 2018 and 2019. We also compared why patients were admitted during the study period, and any pre-existing conditions, with 638 children hospitalised during the same period in 2019. RESULTS: The mean number of daily hospitalisations during the COVID-19 lockdown period was 8.6, which was 59% lower than the 20.9 recorded during the other three periods before COVID-19. There was a significant decrease in the number of patients admitted with infectious (74%) and non-infectious (44%) aetiologies from 2019 to 2020, and these occurred among patients with (58%), and without (55%), pre-existing medical conditions. CONCLUSION: The Israeli COVID-19 lockdown had a dramatic effect on admissions to the paediatric wards of a tertiary hospital.

RESUMEN

BACKGROUND: Symptomatic carotid stenosis is responsible for 10% of all strokes. Currently, CT angiography (CTA) is the main diagnostic tool for carotid stenosis. It is frequently the only diagnostic test preceding recommendations for carotid angioplasty and stenting (CAS) or carotid endarterectomy (CEA). However, the specificity of CTA, especially in patients with 50-70% stenosis, was previously reported to be relatively low. Most studies testing the diagnostic accuracy of CTA were published more than a decade ago. Therefore, we aimed to test the diagnostic accuracy of CTA, performed with current available technology, compared with digital subtraction angiography (DSA) in patients with carotid stenosis. This study aims to characterize patients who were candidates for CAS/CEA based on CTA, but may not require it based on DSA. METHODS: Consecutive candidates for carotid interventions (CAS or CEA) following CTA were identified from prospectively maintained stroke center registries at two large academic centers. As part of our institutional practice all patients had a routine pre-procedural diagnostic DSA. In each patient, degree of carotid stenosis was compared between CTA and DSA. Patients with concordant degree of stenosis on DSA and CTA (true positive group) were compared to patients with a discordant degree of stenosis with less than 50% on DSA (false positive group). RESULTS: Out of 90 patients with significant stenosis on CTA, only 70 (78%) were found to have a significant stenosis on DSA. Severe plaque calcification was significantly more common in the false-positive group. In those patients whose CTA reported stenosis of ≥90%, we found a strong agreement between CTA and DSA (positive predictive value [PPV] - 0.9) for a significant stenosis (≥50%). Conversely, the correlation between CTA and DSA in patients with CTA reported 50-70% stenosis was poor (PPV - 0.29) (p < 0.001). CONCLUSIONS: Our results suggest that despite ongoing radiological progress, the specificity of CTA in accurately assessing carotid stenosis remains relatively low in patients with both moderate stenosis and heavily calcified plaques. Consequently, patients could possibly be referred for unnecessary CEA surgery and may become exposed to associated potential complications.

RESUMEN

Rigid bronchoscopy is the procedure of choice for removal of inhaled foreign bodies. In this retrospective study, we assessed the safety and efficacy of flexible bronchoscopy use in the removal of inhaled foreign bodies in children. One hundred eighty-two patients (median age of 24 months, 58% males) underwent an interventional bronchoscopy for the removal of inhaled foreign body between 2009 and 2019, 40 (22%) by flexible, and 142 (78%) by rigid bronchoscopy. 88.73% of rigid and 95% of flexible bronchoscopies were successful in foreign bodies removal (p value = 0.24). Complication rate was higher among rigid bronchoscopy (9.2% vs. 0%, p = 0.047). From 2017 onwards, following the implementation of flexible bronchoscopy for foreign bodies removal, 64 procedures were performed, 33 (51.6%) flexible, and 31 (48.4%) rigid. Procedure length was shorter via flexible bronchoscopy (42 vs 58 min, p = 0.016). Length of hospital stay was similar.Conclusion: In our hands, flexible bronchoscopy is an efficient and safe method for removal of inhaled foreign bodies in children, with shorter procedure time and minimal complication rate. Flexible bronchoscopy could be considered as the procedure of choice for removal of inhaled foreign bodies in children, by an experienced multidisciplinary team. What is Known: • Rigid bronchoscopy is currently the gold standard for removal of inhaled foreign bodies in children. • Rigid bronchoscopy has a relatively high complication rate compared to flexible bronchoscopy. What is New: • Flexible bronchoscopy is a short, safe, and efficient procedure to remove inhaled foreign bodies in children, compared to rigid bronchoscopy. • Flexible bronchoscopy could be proposed as the procedure of choice for removal of inhaled foreign bodies in children, if an experienced operator is available.

RESUMEN

ABSRACTObjective: Poor adherence to asthma therapy is a major problem in the management of asthma. We aimed to assess if a designed coaching program in children with asthma, coming from low socioeconomic background, will reduce respiratory morbidity and health care utilization.Methods: A prospective interventional pilot study enrolling children aged 3-18 years, admitted to Soroka University Medical Center (SUMC) between October 2015 and May 2016 due to asthma exacerbation. The intervention group was part of a coaching program, which was conducted by medical and paramedical personnel and included a diagnostic and personal educational office visit and a house visit by a nurse educator for asthma. The control group comprised of demographically matched children with asthma, who were admitted to the SUMC, but did not go through any intervention. Medications purchase and health care utilization were extracted from the participants' HMO databases, during 1-year of follow-up.Results: 41 children were enrolled to the intervention group, with 63 children as a control group. No differences were found in asthma-related drugs purchase, number of clinic visits, ER admissions and hospitalizations during the follow-up year, although the intervention group showed a trend towards having a shorter length of stay (2.3 vs. 4.5 days, Cohen's D = 0.44, p = 0.06). The intervention group demonstrated subjective improvement in asthma control, as reflected in Asthma Control Test questionnaires.Conclusions: In this pilot study of coaching program for children with asthma coming from low income families, no decrease in health care utilization was shown. Larger and longer intervention programs are needed.

RESUMEN

OBJECTIVE: To assess whether increment of vitamin D daily intake results in improved serum25(OH) vitamin D levels and reduced respiratory morbidity in premature infants. METHODS: A randomized double-blind clinical pilot trial, including preterm infants born at 32 + 6 to 36 + 6 weeks of gestation. The control group received 400 international units (IU) of cholecalciferol daily compared to 800 IU daily in the intervention group. Levels of 25(OH) vitamin D were measured at birth and 6 and 12 months of age. Respiratory morbidity was followed until 1 year of age. RESULTS: Fifty subjects were recruited during the study period; the median measured 25(OH) vitamin D levels in the control vs intervention groups were: 26.5 vs 34 nmol/L (P = .271) at birth, 99 vs 75.5 nmol/L (P = .008) at 6 months and 72.5 vs 75 nmol/L (P = .95) at 12 months of age. Infants with insufficient vitamin D (<75 nmol/L) levels had higher respiratory morbidity. Serum vitamin 25(OH) D is a fair predictor for respiratory symptoms (area under the curve [AUC], 0.697; 95% confidence interval [CI], 0.509-0.885; P = .047) and for recorded acute respiratory illnesses (AUC, 0.745; 95% CI, 0.569-0.922; P = .012). CONCLUSION: Doubling the daily intake of vitamin D in premature infants did not increase serum 25(OH) vitamin D level, due to poor compliance in the intervention group. We found an inverse association between serum 25(OH) vitamin D and respiratory symptoms, indicating vitamin D deficiency is a fair predictor for respiratory morbidity.

RESUMEN

AIMS: Children with autism spectrum disorder (ASD) tend to suffer from various medical comorbidities. We studied the comorbidity burden and health services' utilisation of children with ASD to highlight potential aetiologies and to better understand the medical needs of these children. METHODS: In this nested case-control study, ASD cases and controls - matched by age, sex and ethnicity in a 1:5 ratio - were sampled from all children born between 2009 and 2016 at a tertiary medical centre. Data were obtained from the hospital's electronic database. Comorbid diagnoses were classified according to pathophysiological aetiology and anatomical/systemic classification of disease. Standard univariate and multivariate statistics were used to demonstrate comorbidities and health services' utilisation patterns that are significantly associated with ASD. RESULTS: ASD children had higher rates of comorbidities according to both pathophysiological and anatomical/systemic classifications (p < 0.001). The most marked significant differences were observed for: hearing impairments (OR = 4.728; 95% CI 2.207-10.127) and other auricular conditions (OR = 5.040; 95% CI 1.759-14.438); neurological (OR = 8.198; 95% CI 5.690-11.813) and ophthalmological (OR = 3.381; 95% CI 1.617-7.068) conditions; and ADD/ADHD (OR = 3.246; 95% CI 1.811-5.818). A subgroup analysis revealed a more profound case-control difference in anaemia rates among girls than in boys (OR = 3.25; 95% CI 1.04-10.19 v. OR = 0.74; 95% CI 0.33-1.64 respectively) and an opposite trend (larger differences in males than in females in cardiovascular diseases (OR = 1.99; 95% CI 1.23-3.23 v. OR = 0.76; 95% CI 0.17-3.45, respectively)). In addition, larger case-control differences were seen among Bedouin children than in Jewish children in a number of medical comorbidities (Breslow-Day test for homogeneity of odds ratio p-value <0.05). Finally, we found that children with ASD tended to be referred to the emergency department and to be admitted to the hospital more frequently than children without ASD, even after adjusting for their comorbidity burden (aOR = 1.28; 95% CI 1.08-1.50 and aOR = 1.28; 95% CI 1.11-1.47 for >1 referrals and admissions per year, respectively). CONCLUSIONS: The findings of this study contribute to the overall understanding of comorbid conditions and health services' utilisation for children with ASD. The higher prevalences of comorbidities and healthcare services' utilisation for children with ASD highlight the additional medical burden associated with this condition.
