Food protein-induced allergic proctocolitis in infants is associated with low serum levels of macrophage inflammatory protein-3a.

Background: Food protein-induced allergic proctocolitis (FPIAP) is a nonimmunoglobulin (IgE)-mediated food hypersensitivity and the exact mechanisms that cause FPIAP are unknown. Chemokines play crucial roles in the development of allergic diseases.

Objective: To examine serum levels of a group of chemokines in infants with FPIAP.

Assessment of Mucosa-Associated Epithelial Chemokine, Thymus-Expressed Chemokine, Periostin and Zonulin Levels in Infants With Atopic Dermatitis.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease. Skin and gut are the organs that first encounter antigens and environmental triggers. The mechanisms behind the relation between skin and gut immune responses in AD have not been identified yet.

May rotavirus vaccine be affect food allergy prevalence?

Incidence of food allergy (FA) during nursing period is 6-8% globally and It is reported %5,7 in Turkey. In our study, the aim is to determine whether the prevalence of food allergy (FA) increases in children vaccinated against rotavirus. The files of 681 infants who are still followed-up were retrospectively evaluated.

A single-center experience of post-transplant lymphoproliferative disorder (PTLD) cases after pediatric liver transplantation: Incidence, outcomes, and association with food allergy.

Background/aims: We evaluated our 16-year single-center experience of pediatric post-transplant lymphoproliferative disorder (PTLD) cases who underwent liver transplantation between 2001 and 2017.

Materials And Methods: Of the 236 pediatric patients who underwent liver transplantation between 2001 and 2017, the clinical and laboratory data of eight patients diagnosed with PTLD were reviewed. The pre-transplant Epstein-Barr virus (EBV) status of 172 patients was also recorded.

Effect of mometasone furoate nasal spray on the DNA of nasal mucosal cells.

Background/aim: Allergic rhinitis (AR) is a respiratory disease caused by inflammation of the nasal mucosa. Intranasal corticosteroids (ICs) are an effective treatment for AR; however, their use has been associated with atrophy in nasal mucosae. Because DNA damage has been linked to several chronic diseases, we hypothesize that use of ICs could cause DNA damage in nasal mucosa cells, leading to mucosal atrophy and septal perforation.

Serum Vitamin D Levels in Children with Recurrent Respiratory Infections and Chronic Cough.

Objectives: To evaluate serum vitamin D levels in cases of recurrent respiratory infections and chronic cough and to investigate the effect of vitamin D therapy on recurrence of the diseases.

Methods: This prospective observational study was performed by comparing serum vitamin D levels in children with recurrent respiratory infections, chronic cough and healthy children. One-hundred-one children with chronic cough, ninety-eight children with recurrent respiratory infections and one-hundred-twenty-four healthy children were enrolled in the study.

Evaluation of angiopoietin 1 and 2, vascular endothelial growth factor, and tumor necrosis factor alpha levels in asthmatic children.

Asthma is characterized by chronic airway inflammation that is associated with structural changes termed airway remodeling. Recently, cytokines/mediators that augment inflammation have been attracting attention in this field. The aim of this study was to evaluate serum angiopoietin (Ang)-1, Ang-2, vascular endothelial growth factor (VEGF), and tumor necrosis factor (TNF) alpha values, which have important roles in inflammation, angiogenesis, and remodeling in asthmatic children.

Food allergy after liver transplantation in children: a prospective study.

Food allergy has been increasingly reported in children who had orthotopic liver transplantation (OLT). We aimed to conduct a prospective study to investigate the prevalence of sensitizations and food allergy in pediatric OLT recipients. We also aimed to identify potential risk factors.

Plasminogen activator inhibitor-1 gene 4G/5G polymorphism in Turkish children with asthma and allergic rhinitis.

Plasminogen activator inhibitor (PAI-1) has an essential role in tissue remodeling after inflammation. Recent literature revealed only one study evaluating PAI-1 4G/5G gene polymorphism in children with asthma and none in children with allergic rhinitis. We aimed to investigate distribution of PAI-1 4G/5G polymorphism in a group of Turkish children with asthma and allergic rhinitis and compare these findings with those obtained in normal peers.

Double invasive fungal infection and typhlitis in children with acute lymphoblastic leukemia.

Invasive fungal infection is one of the major causes of morbidity and mortality in immunocompromised patients. The occurrence of two invasive fungal infections in one patient at the same time is quite rare. Here the authors report on two adolescent patients with acute lymphoblastic leukemia who developed combined invasive pulmonary aspergillosis and hepatosplenic candidiasis during chemotherapy.

Laryngitis and neutropenia from parvovirus-B19.

Parvovirus-B19 has been reported a rare cause of acute laryngitis. Here, we described an 11-month-old girl who had prolonged acute laryngitis and neutropenia associated with parvovirus-B19 infection. Intravenous immunoglobulin therapy resulted in resolution of her symptoms, except neutropenia.

Airway hyperreactivity detected by methacholine challenge in children with sickle cell disease.

Recent studies have emphasized the presence of airway hyperreactivity (AHR) in children with sickle cell disease (SCD). However, various tests for the detection of AHR have yielded distinctly different results in these patients. This study identified AHR via a methacholine challenge test (MCT) in a group of children with SCD (31 patients; age range, 6-16 years).

Evaluation of hypothalamic-pituitary-adrenal axis suppression by low-dose (0.5 microg) and standard-dose (250 microg) adrenocorticotropic hormone (ACTH) tests in asthmatic children treated with inhaled corticosteroid.

The aim of this study was to compare the results of low-dose (LDT) and standard-dose (SDT) ACTH tests in the assessment of adrenal function in 30 asthmatic children (mean age 9.35 +/- 1.9 years, 19 boys) who were treated with budesonide Turbohaler at conventional 400 microg or 600 microg daily doses for 8 weeks by a prospective, randomized, and open parallel study.
