BACKGROUND: Maternal breast milk (MBM) is enriched in microRNAs, factors that regulate protein translation throughout the human body. MBM from mothers of term and preterm infants differ in nutrient, hormone, and bioactive-factor composition, but the microRNA differences between these groups have not been compared. We hypothesized that gestational age at delivery influences microRNA in MBM, particularly microRNAs involved in immunologic and metabolic regulation. METHODS: MBM from mothers of premature infants (pMBM) obtained 3-4 weeks post-delivery was compared with MBM from mothers of term infants obtained at birth (tColostrum) and 3-4 weeks post-delivery (tMBM)...

BACKGROUND: Delayed diagnosis of childhood Takayasu arteritis (TA) is common due to its atypical symptoms. The objective of the present study was to summarize the clinical features of childhood TA to raise awareness and improve management. METHODS: Eleven children diagnosed with TA at our hospital were enrolled. Clinical information, diagnosis, treatment, and outcome were then examined retrospectively. The Pediatric Vasculitis Activity Score (PVAS) and the Indian Takayasu Clinical Activity Score (ITAS2010) were used to assess disease activity...

BACKGROUND: The occurrence of meningitis in children >5 years old may be associated with specific predisposing factors that can be anatomic, such as cerebrospinal fluid fistula or breach, or related to genetic susceptibility or N inborn or acquired immunologic defect. This study aimed to assess the anatomical and immunologic risk factors in children >5 years old with pneumococcal meningitis and prospectively enrolled in the French national meningitis network. METHODS: We analyzed all data for children who were 5-15 years old with a diagnosis of pneumococcal meningitis between 2001 and 2013...

Eosinophilic esophagitis is an underrecognized chronic condition in which symptoms of gastroesophageal reflux are accompanied by eosinophilia in the esophagus. This disorder affects both children and adults and is associated with a history of other atopic disorders, particularly food allergies. This case study discusses the epidemiology of eosinophilic esophagitis and the proper procedures for diagnosis, referral, and management using the dietary restrictions and pharmacologic treatment included in the clinical recommendations issued by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition; the American Academy of Allergy, Asthma, and Immunology; and the American College of Gastroenterologists...

BACKGROUND: Seqirus 2010 Southern Hemisphere split-virion trivalent inactivated influenza vaccine (IIV3) was associated with increased febrile reactions in children. Studies in vitro concluded that increasing concentrations of splitting agent decreased residual lipids and attenuated proinflammatory cytokine signals associated with fever. We assessed immunogenicity and safety of a quadrivalent inactivated influenza vaccine (IIV4; produced using higher concentration of splitting agent) versus a United States-licensed comparator IIV4 in healthy children aged 5-17years...

Atopic dermatitis (AD) is a chronic pruritic inflammatory disease that commonly presents in the pediatric population. Although definitions and diagnosis of AD have largely been agreed upon, allergists and dermatologists have similar and divergent approaches to the management of AD. This review facilitated integration of the American Academy of Allergy, Asthma & Immunology/American College of Allergy, Asthma & Immunology Joint Task Force 2012 AD Practice Parameter and the 2014 American Academy of Dermatology guidelines to highlight the basic principles of AD management and discuss therapies and management of AD from the distinct perspectives of the allergist and dermatologist...

BACKGROUND: Comparative studies have demonstrated that asthma education to pediatric patients decreases average hospital usage and that allergy specialists provide stronger asthma education and more improved outcomes. OBJECTIVE: To evaluate the real-world benefits of allergy subspecialty involvement outside inpatient consultation and the impediments for patients in establishing allergy subspecialty care. METHODS: The study population was composed mostly of minority children 0 to 18 years old seen at a large university-affiliated stand-alone children's hospital who had a hospital discharge diagnosis of asthma from 2009 to 2013...

This retrospective study examined the clinical significance of FCM-MRD in 36 patients with ALL and 29 patients with AML after their first allogeneic HSCT. Hematological (FCM-MRD ≥5.0%) and molecular relapse (FCM-MRD <5.0%) were first detected in 10 and two patients with ALL and in seven and eight patients with AML, respectively. Eight of 10 patients with molecular relapse eventually progressed to hematological relapse, although most were treated with immunological intervention by aggressive discontinuation of immunosuppressive therapy or donor lymphocyte infusion...

OBJECTIVES: Recent evidence points towards an active immunological role of intra-abdominal adipose tissue in Crohn's disease (CD). We quantified the abdominal adipose tissue compartments using magnetic resonance imaging (MRI) in 27 pediatric CD patients compared with 14 controls undergoing MRI examination for other reasons. METHODS: Total (TAAT), subcutaneous (SCAT) and intra-abdominal (IAAT) adipose tissue areas were measured by semiautomatic segmentation on a transverse slice centered on the umbilicus (mean ± standard deviation in cm) using standard T1 weighted sequences...

PURPOSE: The disease concept of sick building syndrome (SBS) is still unclear. Ocular mucous membrane irritation is one of the major symptoms of SBS. However, the immunological aspects of the ocular complications of SBS are not yet clarified. The clinical and allergological aspects of SBS cases with ocular disorders with special reference to allergic conjunctival diseases (ACD) were analyzed, especially with respect to local immunological features. METHODS: Twelve cases of SBS with ocular findings and 49 cases of ACD (allergic conjunctivitis [AC], atopic keratoconjunctivitis [AKC], and vernal keratoconjunctivitis [VKC]) for comparison were evaluated...

Interstitial processes in the lungs of children can be due to several underlying diseases. Knowledge of the child's age is important as genetic aberrations play a major role in diseases in the first 2 years, whereas immunological diseases are more common starting in kindergarden age. In general lung diseases are rare in children, which makes the diagnostics difficult and results in a delayed diagnosis. In addition, pediatric pulmonologists are often very reluctant to perform lung biopsies due to a lack of a specialized pathologist...

Adverse food reactions are far more often perceived than objectively verified. In our scientific knowledge on non-allergic adverse reactions including the so called histamine intolerance, there are large deficits. Due to the fact that this disorder is increasingly discussed in the media and the internet, more and more people suspect it to be the trigger of their symptoms. The scientific evidence to support the postulated link between ingestion of histamine and adverse reactions is limited, and a reliable laboratory test for objective diagnosis is lacking...

INTRODUCTION: At the present time, the study of mechanisms of recognition of foreign agents, which is realized by means of Toll-like receptors (TLR) of the innate immune system, has become one of the main tasks of clinical immunology. The aim of our study was to investigate the prevalence of polymorphism of Toll-like receptor 4 (Asp299Gly, Gly299Gly) among children with chronic pyelonephritis (CP) and determine the association of this TLR4 polymorphism with phenotypic features of chronic pyelonephritis and level of interleukin-6 (IL-6)...

Tranexamic acid is an anti-fibrinolytic agent frequently used in pediatric surgery. Common side effects include nausea, flushing, and headache, but in rare instances, it may produce anaphylaxis; with only one previously reported case in a 72-year-old man. We report a case of a delayed anaphylactic reaction in a pediatric patient undergoing posterior spine fusion; and discuss the intraoperative management of the acute event, immunologic confirmation, and subsequent anesthetic approach.

Several types of vaccine-delivering tumor-associated antigens (TAAs) have been developed in basic and clinical research. Wilms' tumor 1 (WT1), identified as a gene responsible for pediatric renal neoplasm, is one of the most promising TAA for cancer immunotherapy. Peptide and dendritic cell-based WT1 cancer vaccines showed some therapeutic efficacy in clinical and pre-clinical studies but as yet no oral WT1 vaccine can be administrated in a simple and easy way. In the present study, we constructed a novel oral cancer vaccine using a recombinant Bifidobacterium longum displaying WT1 protein...

Esophageal granular cell tumors (GCTs) are rare. Eosinophilic esophagitis (EoE) is an immune-mediated disease characterized by esophageal eosinophilia despite proton pump inhibitor (PPI) therapy. Given that GCTs occur at sites of scarring and inflammation, we sought to determine the prevalence of EoE in patients with esophageal GCTs. Our center's pathology database was searched for GCT specimens from 1995 to 2014. Slides were blindly rereviewed. GCTs were scored for atypical cytological features. Presence and number of eosinophils in the tumor and the surrounding esophageal epithelium and any EoE features were recorded...

Five years have passed since the Japanese Pediatric Guideline for Food Allergy (JPGFA) was first revised in 2011 from its original version. As many scientific papers related to food allergy have been published during the last 5 years, the second major revision of the JPGFA was carried out in 2016. In this guideline, food allergies are generally classified into four clinical types: (1) neonatal and infantile gastrointestinal allergy, (2) infantile atopic dermatitis associated with food allergy, (3) immediate-type of food allergy (urticaria, anaphylaxis, etc...
