This study aimed to investigate secretory immunoglobulin A (SIgA) levels in the nasal fluid of children who were either being treated for their allergic rhinitis (AR) with intranasal mometasone furoate or were not receiving treatment.Publication Metadata only Oxidative Stress in Children with Noninfectious Acute Urticaria(2016-03-01T00:00:00Z) ÖZKAYA, EMİN; YAZICI, MEBRURE; ERENBERK, UFUK; Dilek, Fatih; Dundaroz, Rusen; ÖZKAYA, EMİN; YAZICI, MEBRURE; ERENBERK, UFUK; İŞCAN, AKINPlasma oxidative stress parameters such as as total oxidant status (TOS) and total antioxidant status (TAS) were well studied in some chronic allergies, but their role is not well known in acute allergic disease such as acute urticaria (AU). The aim of this study is to investigate the oxidative and antioxidative status in children with AU. Eighty-seven children with noninfectious AU and 70 healthy controls were enrolled in the study. Blood samples were taken for complete blood count, serum immunoglobulin E (IgE), and C-reactive protein (CRP) levels routinely and for TOS and TAS. The skin prick test was performed and/or specific IgE assays were performed as indicated. Blood samples were also taken for TAS and TOS in the control group. Forty-eight (55%) of the children with AU were male, 39 (45%) of them were female. Mean ages were 6 +/- 2.02 and 7 +/- 1.38 years in the study and control groups, respectively. TOS levels were significantly high and TAS levels were significantly lower in the acute urticarial group (P < 0.001) than controls. There was no significant correlation between age, total IgE levels, or eosinophil count and TAS and TOS levels in children with AU. Plasma TOS levels are elevated in children with AU. The high level of TOS indicates that children with AU were exposed to severe oxidative stress.Publication Open Access Enuresis Nocturna in children with asthma: prevalence and associated risk factors(2016-06-01T00:00:00Z) ÖZKAYA, EMİN; Aydin, Seren Calis; YAZICI, MEBRURE; Dundaroz, Rusen; ÖZKAYA, EMİN; YAZICI, MEBRURE; İŞCAN, AKINBackground: Enuresis Nocturna (EN) is a common disorders in childhood. Although many different underlying pathophysiological mechanisms have been proposed to explain EN, its etiology is multifactorial. Some reports demonstrate that there is an association between EN and allergic diseases. To study (1) the prevalence of EN in children with asthma, (2) to determine the possible risk factors for EN in asthmatic children.Publication Open Access Effect of Montelukast Monotherapy on Oxidative Stress Parameters and DNA Damage in Children with Asthma(2015-01-01) DILEK, Fatih; Ozkaya, EMİN; Kocyigit, ABDÜRRAHİM; Yazici, MEBRURE; KESGIN, Siddika; GEDIK, Ahmet Hakan; Cakir, ERKAN; ÖZKAYA, EMİN; KOÇYİĞİT, ABDÜRRAHİM; YAZICI, MEBRURE; ÇAKIR, ERKANBackground: There is ample knowledge reported in the literature about the role of oxidative stress in asthma pathogenesis. It is also known that the interaction of reactive oxygen species with DNA may result in DNA strand breaks. The aim of this study was to investigate if montelukast monotherapy affects oxidative stress and DNA damage parameters in a population of pediatric asthma patients. Methods: Group I consisted of 31 newly diagnosed asthmatic patients not taking any medication, and group II consisted of 32 patients who had been treated with montelukast for at least 6 months. Forty healthy control subjects were also enrolled in the study. Plasma total oxidant status (TOS) and total antioxidant status (TAS) were measured to assess oxidative stress. DNA damage was assessed by means of alkaline comet assay. Results: The patients in both group I and group II had statistically significant higher plasma TOS (13.1 ± 4 and 11.1 ± 4.1 μmol H2O2 equivalent/liter, respectively) and low TAS levels (1.4 ± 0.5 and 1.5 ± 0.5 mmol Trolox equivalent/liter, respectively) compared with the control group (TOS: 6.3 ± 3.5 μmol H2O2 equivalent/liter and TAS: 2.7 ± 0.6 mmol Trolox equivalent/liter; p < 0.05). DNA damage was 18.2 ± 1.0 arbitrary units (a.u.) in group I, 16.7 ± 8.2 a.u. in group II and 13.7 ± 3.4 a.u. in the control group. There were statistically significant differences only between group I and the control group (p < 0.05). Conclusions: According to the findings, montelukast therapy makes only minimal but not statistically significant improvement in all TOS, TAS and DNA damage parameters.Publication Open Access Renal tubular function and urinary N-acetyl-beta-d-glucosaminidase and kidney injury molecule-1 levels in asthmatic children(2016-12-01) DEMIR, Aysegul Dogan; GOKNAR, Nilufer; OKTEM, Faruk; Ozkaya, EMİN; Yazici, MEBRURE; Torun, EMEL; Vehapoglu, Aysel; KUCUKKOC, Mehmet; ÖZKAYA, EMİN; YAZICI, MEBRURE; TORUN, EMEL; VEHAPOĞLU TÜRKMEN, AYSELBackground: Asthma is a chronic inflammatory disorder of the airways which results in chronic hypoxia. Chronic hypoxia and inflammation can affect renal tubular function. Objectives: The aim of this study was to investigate renal tubular function and early kidney injury molecules such as urinary N-acetyl-betaglucosaminidase (NAG) and kidney injury molecule-1 (KIM-1) excretion in children with asthma. Methods: Enrolled in the study were 73 children diagnosed with asthma and 65 healthy age- and gender-matched control subjects. Urine pH, sodium, phosphorus, potassium, microalbumin, creatinine, NAG, KIM-1, and serum creatinine, sodium, phosphorus were evaluated. The diagnosis of asthma and classification of mild or moderate were done according to the Global Initiative for Asthma guidelines. Results: Serum sodium, phosphorus, creatinine, and urinary microalbumin were within normal levels in the both groups. Urinary pH, sodium, potassium, phosphorus, microalbumin, and KIM-1 excretions were similar between the control and study groups. Tubular phosphorus reabsorption was within normal limits in two groups. Urine NAG was elevated in the study group (P = 0.001). Urinary KIM-1 and NAG levels were positively correlated (r = 0.837; P = 0.001). When children with mild and moderate asthma were compared, all of the parameters were similar (P >0.05). Conclusions: This study showed that chronic asthma can lead to subtle renal impacts. We suggest that in children with asthma, urinary NAG level is a more valuable parameter to show degree of renal tubular injury than markers such as microalbumin and KIM-1. Chronic hypoxy and inflammation probably contributes to these subclinical renal effects.Publication Metadata only The Association Between Paranasal Mucous Retention Cysts and Allergic Sensitization(2021-01-01T00:00:00Z) USTABAŞ KAHRAMAN, Feyza; YAZICI, MEBRURE; BÜYÜKPINARBAŞILI, NUR; Soylu, Nihal; İŞCAN, AKIN; ÖZKAYA, EMİN; USTABAŞ KAHRAMAN, FEYZA; YAZICI, MEBRURE; BÜYÜKPINARBAŞILI, NUR; İŞCAN, AKIN; ÖZKAYA, EMİNObjective: Although there is no consensus regarding the etiology of paranasal mucous retention cysts (MRCs) in the literature, several studies suggest an allergic etiology. This study aimed to investigate a potential association between paranasal MRCs diagnosed with MRI scans and allergic sensitization in the pediatric population.Publication Open Access Oxidative Stress in Children with Chronic Spontaneous Urticaria(2016-01-01) DILEK, Fatih; Ozceker, Deniz; Ozkaya, EMİN; Guler, Nermin; Tamay, Zeynep; KESGIN, Siddika; Yazici, MEBRURE; Kocyigit, ABDÜRRAHİM; ÖZKAYA, EMİN; YAZICI, MEBRURE; KOÇYİĞİT, ABDÜRRAHİMThe pathogenesis of chronic spontaneous urticaria (CSU) has not been fully understood; nevertheless, significant progress has been achieved in recent years. The aim of this study was to investigate the possible role of reactive oxygen species (ROS) in the pathogenesis of CSU. Sixty-two children with CSU and 41 healthy control subjects were enrolled in the study. An extensive evaluation of demographic and clinical features was done, and serum oxidative stress was evaluated by plasma total oxidant status (TOS) and total antioxidant status (TAS) measurements.The median value of plasma TOS was found to be 10.49 𝜇mol H2O2 equiv./L (interquartile range, 7.29–17.65) in CSU patients and 7.68 𝜇mol H2O2 equiv./L (5.95–10.39) in the control group. The difference between the groups was statistically significant (𝑝 = 0.003). Likewise, the median plasma TAS level in the CSU group was decreased significantly compared to that of the control group (2.64 [2.30–2.74] versus 2.76 [2.65–2.86] mmol Trolox equiv./L, resp., 𝑝 = 0,001). Our results indicated that plasma oxidative stress is increased in children with CSU when compared to healthy subjects, and plasma oxidative stress markers are positively correlated with disease activityPublication Metadata only Alerjik Rinitli Çocuklarda Nazal Staphylococcus aureus Taşıyıcılığı(2017-10-01) DILEK, FATIH; CEYLAN, AYŞE NUR; ÖZKAYA, EMİN; GÜLTEPE, BİLGE; YAZICI, MEBRURE; CEYLAN, AYŞE NUR; ÖZKAYA, EMİN; SÜMBÜL, BİLGE; YAZICI, MEBRURE
