Trace elements are micronutrients that are present in small amounts in the body and are essential for normal functioning of the immune and antioxidant systems. Inflammation and oxidative stress are major pathogenic mechanisms in the development of atopic dermatitis (AD). The role of micronutrients in AD has been investigated in a limited number of studies, although the results are contradictory.In this study, we examined the levels of iron, copper, and magnesium in serum and the level of zinc in erythrocytes in children with AD. We compared our findings with those of a healthy control group.The study population comprised 92 AD patients and 70 controls. We performed a complete blood count and measured levels of iron, copper, and magnesium in serum and levels of zinc in erythrocytes.We found that serum magnesium and erythrocyte zinc levels were lower in children with AD than in the control group; levels of copper and iron did not differ between the groups. The levels of micronutrients studied were not correlated with disease severity.Evaluation of zinc and magnesium levels in children with AD could prove useful. The role of micronutrients in the pathogenesis and course of AD warrants further study.

- Abstract
Background: Cat allergen is among the most common household allergens and can cause respiratory allergies and anaphylaxis in children. Objective: The aim of this study was to evaluate the characteristics of cat allergies in children and the impact of the coronavirus disease 2019 (COVID-19) pandemic on these characteristics. Methods: The study included pediatric patients with cat allergen sensitization demonstrated by skin-prick test (SPT) over a period of 2 years: 1 year before and 1 year during the pandemic. Demographic data, clinical features, and laboratory findings were evaluated from the patients' records. Results: Of 7428 SPTs performed, 566 patients (7.6%) were sensitized to cat allergen (56% boys; median age, 11 years). Fifty-eight percent of the patients (n = 329) presented during the pandemic period, 44.5% (n = 252) had symptoms with cat exposure, and 9% (n = 51/566) had anaphylaxis. Allergic rhinitis and asthma were present in 76% (n = 431) and 46.6% (n = 264) of the patients, respectively. When compared to prepandemic period, patients who presented during the pandemic had higher rates of cat sensitization (15% in pandemic group versus 4.4% in prepandemic group of all SPTs performed; p < 0.05), cat ownership (29.1% versus 13.9%; p < 0.001), and symptoms on cat exposure (51% versus 34%; p < 0.001). Factors that predicted symptom development in the patients who were cat sensitized were induration > 5 mm on SPT (odds ratio [OR] 1.9 [95% confidence interval {95% CI}], 1.1-3.2), cat ownership (OR 9.2 [95% CI, 4.9-17.3]), close contact with a cat owner (OR 7.1 [95% CI, 4-12]), allergic rhinitis (OR 3.1 [95% CI, 1.6-5.8]), conjunctivitis (OR 4.7 [95% CI, 2-10]), and atopic dermatitis (OR 2.2 [95% CI, 1-4.7]). Conclusion: We observed an increase in the prevalence of cat allergy among children during the COVID-19 pandemic. Care must be taken in terms of anaphylaxis in patients who were cat sensitized.

- Abstract
Background/aim: Ig level assessment is frequently used in the diagnosis and follow-up of immunodeficiency, as well as in studies investigating the prevalence of low serum Ig level in specific diseases., Materials and Methods: Patients who underwent Ig testing in the inpatient and outpatient clinics of our hospital in the years 2010–2016 were included. The Ig levels of the patients were assessed separately according to two reference systems commonly used in Turkey and another reference system used in the USA., Results: A total of 20,138 patients (57.6% male) were included in the study. The median age of the patients was 55.7 months (interquartile range: 23.1–96.7). According to the reference intervals determined by Tezcan et al., 30.6% of the patients were deficient in one or more Ig values. This rate was 4 times higher than those based on the reference intervals determined by Aksu et al. (7.7%) and those in the Nelson Textbook of Pediatrics (6.8%). We also determined that the frequency of low Ig levels with three reference systems, Conclusion: In this study, we found that the rates of low Ig level in a group of pediatric patients differed significantly when evaluated using three different reference systems for age-related serum Ig levels

- Abstract
Background: Despite the increasing frequency of anaphylaxis, there is inadequate information on the etiology and clinical features in various countries, regions and age groups, especially in developing countries., Objective: Our aim is to assess the etiology and clinical findings of anaphylaxis in Turkey. Gathering reliable data about the etiology and clinical findings of anaphylaxis in the general population will decrease the related morbidity and mortality., Method: We obtained the names and phone numbers of individuals who had been prescribed an epinephrine auto-injector with a diagnosis of anaphylaxis from ministry of health. Demographic data, clinical history of the first episode of anaphylaxis including the triggering agent, clinical findings, course of hospitalization, and the management of anaphylaxis were obtained by phone survey., Results: A total of 843 patients with a mean age of 21.4±17.3 years were evaluated. There was a significant male predominance among children younger than 10 years of age but a female predominance in older subjects. The most common causes of anaphylaxis were foods(40.1%) in children and bee venom(60.8%) in adults. The biphasic reaction rate was 4.3% and the median length of stay at an emergency department was 4.0 hours. Almost 60% of the patients had recurrent anaphylaxis episodes. Only 10.7% of the cases were prescribed an epinephrine auto-injector at their first anaphylaxis episode and only 59.2% of the patients were referred to an allergist during discharge from the emergency department., Conclusions: In Turkey, bee venom was the most common cause of anaphylaxis, followed by food and drug. While more than a half of patients reported recurrent attacks; only 10% had been prescribed epinephrine auto-injector kit after their first episode. Strategies to improve the anaphyalxis management are therefore urgently required.

- Abstract
Background/aim: IgA deficiency is the most common human primary immunodeficiency. The prevalence of allergic disorders and autoimmunity is thought to be increased in selective IgA deficiency (sIgAD). However, it is currently unclear if these disorders coincide within these families. We aimed to evaluate the frequency of allergic and autoimmune disorders in children with sIgAD and their first-degree relatives (FDRs)., Materials and Methods: The study included 81 children diagnosed with sIgAD and 274 of their FDRs. The presence of allergic and autoimmune disorders was evaluated and serum antithyroglobulin and antithyroid peroxidase levels were measured in both patients and their first-degree relatives., Results: The mean age of the patients was 9.9 ± 3.9 years. Among the patients with sIgAD, 45.7% of them had at least one allergic disorder and 17.3% of them had at least one autoimmune disorder. The frequencies of asthma, allergic rhinitis, and eczema in the FDRs of sIgAD patients were 10.9%, 9.1%, and 7.7%, respectively. Among their FDRs, 14.6% had autoimmunity, compared to an estimate of 5% in the general population., Conclusion: Increased frequency of allergic and autoimmune disorders in patients with sIgAD and their FDRs suggests a possible common predisposing genetic component for sIgAD and autoimmunity in these families.

- Abstract
Background: Chronic urticaria (CU) is a skin disorder defined as daily or almost daily exhibition of pruritic and transient wheals that last for 6 weeks. CU is divided into two subtypes: chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU)., Objectives: To evaluate the clinical features, possible causes, associated findings, and laboratory results of different subtypes of CU in children according to a new classification., Methods: In this study, we evaluated the clinical features, laboratory investigations, and provocation tests of children with different subtypes of CU according to a new classification., Results: Two hundred and twenty-two children (59.9% girls) were enrolled in the study. Of the study patients, 59.9% and 40.1% were diagnosed as having CSU and CIndU, respectively. Antithyroid antibody levels were positive in 7.1% of the patients with CSU, 32.8% of the children had positive 14C-urea breath test results, and 6.5% of the patients had positive stool examination results for parasites. Autologous serum skin test results were positive in 53.5% of the patients with CSU. Of the patients with CIndU, 77.5% had symptomatic dermographism, 16.8% had cold urticaria, 2.2% had cholinergic urticaria, 2.2% had solar urticaria, and 1.1% had aquagenic urticaria., Conclusion: Children with CSU represent the majority of patients with CU, and more than a half of these patients might have autoimmune urticaria. Symptomatic dermographism was the most common type of CIndU.

- Abstract
Background: In this study, our goal is to evaluate the consistency between TRACK and the asthma control levels assessed according to the GINA and NAEPP guidelines in children younger than 5 years of age., Methods: Patients under 5 years old, who were followed up for recurrent wheezing for at least 1 year have been included. Parents were given the TRACK questionnaire and the control level of asthma according to GINA and NAEPP guidelines were determined by a pediatric allergist blinded to TRACK scores. Patients were classified into two groups regarding the compatibility of the control level between TRACK and both GINA and NAEPP guidelines., Results: A total of 365 questionnaires were evaluated. The TRACK cut-off point of 80 provided the most consistent balance between sensitivity and specificity for the compatibility with both GINA and NAEPP (for GINA 0.763 and 0.663, kappa = 0.487, p < 0.001 and for NAEPP 0.761 and 0.769, kappa = 0.524, p < 0.001, respectively). When 80 was taken as the cut-off value for TRACK, the compatibility rate of asthma control levels between TRACK and GINA and TRACK and NAEPP was 71.0 and 76.4%, respectively. About 70.1% of the patients who had TRACK scores over 80 and had mild asthma were grouped as controlled according to GINA and 50.0% of patients who had TRACK scores over 80 and had moderate to severe asthma was grouped as uncontrolled according to GINA (p = 0.019)., Conclusion: TRACK is compatible with NAEPP and GINA in majority of asthmatic children under 5 years of age. Nevertheless, there is a discrepancy between guidelines and TRACK scores; therefore, it should be used in conjunction with a detailed clinical examination in order to make a better decision for assessing the control levels and management plan.

- Abstract
Objective: The aim of this study was to investigate the kidney growth and renal functions in children receiving recombinant human growth hormone (rhGH) treatment., Materials and Methods: A total of 37 children who received rhGH for 1.5 years before the study was started and 48 healthy controls were included at first evaluation. Hormone levels were determined and kidney sizes were measured by ultrasound. Kidney functions were assessed by serum creatinine and estimated glomerular filtration rate (eGFR). After 3 years of first evaluation, 23 patients were re-assessed., Results: Kidney sizes were found to be lower in rhGH received children compared with controls at first evaluation (p<0.05). Significant positive correlations were found between anthropometric measurements and kidney length and kidney volume (p<0.05). Height was the most significant predictor of kidney volume in rhGH received children (p<0.001). After 3-years of follow-up significantly increases were found in kidney length and volume compared with the first measurements (p<0.05). Increase percentage of body height was similar to increasing percent of kidney length and liver long axis (14.2%, 11.7.1% and 7.7%, respectively, p>0.05). Although no abnormal renal function test results were found at first and second evaluations; rhGH received children had significantly lower eGFR, at first evaluation, compared with controls; however, renal functions significantly increased after 3 years of follow-up (p<0.05)., Conclusions: In conclusion, effect rhGH treatment on kidney growth is parallel to growth in body height and other visceral organs. A 3-years rhGH treatment resulted in significant increases in renal functions.

- Abstract
Anaphylaxis is a potentially life-threatening condition. There are limited data about the etiology and the clinical characteristics in developing countries. This study aimed to investigate the clinical characteristics of anaphylaxis patients attending our pediatric allergy clinic. We conducted a prospective analysis of patients who were admitted to our allergy clinic for anaphylaxis from 2010 to 2012. Ninety-six patients were evaluated during the study period. The mean age was 7.4 ± 5.2 years. Venom, food, and drugs were the most common causative agents responsible for 31 (32.3%), 30 (31.3%), and 26 (27.1%) of the cases, respectively. Foods implicated most frequently were peanuts and nuts (n = 9; 30.0%), cow's milk (n = 7; 23.3%), and egg white (n = 6; 20.0%). The clinical manifestations during anaphylaxis in order of frequency were cutaneous (97.9%), respiratory (86.5%), gastrointestinal (42.7%), neurological (37.5%), and cardiovascular symptoms (30.2%). A biphasic course was noticed in five cases (5.2%). Of the 91 patients, 79 (86.8%) received H1-antihistamines, 73 (80.2%) received corticosteroids, 40 (44.4%) received adrenaline, 38 (41.8%) received fluid replacement therapy, 18 (19.8%) received β2-mimetics, and 8 (8.8%) received H2-antihistamines. According to severity, 7.3% of patients had mild, 59.4% had moderate, and 33.3% had severe anaphylaxis. Food and bee venom allergy were the most common etiologies. Adrenaline, the first-line treatment of anaphylaxis, was administered in only 44.4% of our cases.

- Abstract
The effect of hypothyroidism on kidney size has not been studied in children. The aim of this study was to examine the role of congenital hypothyroidism and levothyroxine (L-thyroxine) treatment on renal growth. Forty children with congenital hypothyroidism and 37 healthy controls were prospectively included. The mean age of patients was 8.2+/-4.7 years. Patients had lower height and weight standard deviation scores compared with controls. The mean L-thyroxine initial age and treatment duration were 37.0 and 60.5 months, respectively. In 62.5% of patients, L-thyroxine was initiated after 6 months of age, and 60.0% of patients had severe hypothyroidism. Patients had lower kidney length and total kidney volume compared with controls (P < 0.05). No significant differences were found in kidney volume/body weight and kidney volume/ body height ratios between patients and controls (P > 0.05). Multiple regression analysis showed significant relationship between relative kidney volume and average free thyroxine level (P < 0.05). No significant differences in kidney sizes were found between patients who had L-thyroxine initiated before and after 6 months of age or between mild/moderate and severe hypothyroidism at diagnosis (P > 0.05). In conclusion, normal renal growth can be accomplished with L-thyroxine replacement despite considerable delay in treatment initiation and/or severe hypothyroidism.
