ABSTRACT
AIM: Primary immunodeficiencies (PIDs) are a heterogeneous disorder group characterized by an impaired immune system, leading to an increased susceptibility to infections and a wide range of clinical manifestations, including gastrointestinal (GI) complications. This study aimed to assess the GI manifestations of PID patients and highlight the significance of atypical gastrointestinal symptoms in the early diagnosis of these patients. METHODS: A retrospective analysis was conducted on pediatric patients diagnosed with PIDs at Selcuk University Medical Faculty from 2011 to 2021. The study focused on demographic data, clinical presentation, genetic mutations, and GI manifestations, including endoscopic evaluation. Patients were categorized according to the International Union of Immunological Societies (IUIS) PID classifications. Statistical analyses were performed to identify significant associations between PID types and GI manifestations. RESULTS: The cohort comprised 101 patients, with 46% presenting with GI symptoms, including malnutrition and chronic diarrhea, as the most common findings. Primary antibody deficiency (PAD) emerged as the most prevalent PID with GI involvement, followed by combined immunodeficiencies (CID) with associated or syndromic features. Endoscopic evaluations revealed inflammatory bowel disease (IBD)-like colitis in a significant subgroup of patients. The analysis showed that some GI symptoms were more common in specific PID categories, highlighting the importance of early gastroenterological assessment in PID patients. CONCLUSION: Recognition of common GI symptoms in pediatric patients with PIDs may facilitate early diagnosis and prompt multidisciplinary management, potentially improving patient outcomes. The study highlights the necessity of considering PIDs in diagnosing persistent or severe GI symptoms in children.

Background/aim: Data on the prevalence of allergic diseases in children with proven drug allergies are limited. We aim to evaluate the frequency of allergic comorbidity in children with proven common drug allergies. Materials and methods: Children with drug hypersensitivity confirmed by diagnostic allergy tests at our center between January 2010 and December 2020 were screened retrospectively. Patients with the most common drug allergies (due to antibiotics, nonsteroidal antiinflammatory drugs [NSAIDs], and antiepileptic drugs) were selected for analysis. Age, sex, the culprit drug, initial reaction characteristics, diagnostic test results, and the study physician who diagnosed concomitant allergic diseases were noted. Results: A total of 168 patients (boys, 51.2%) with a median age of 12 years (IQR = 8-16.3) were included in the study. The culprit drug was an antibiotic in 63% (n = 106), NSAID in 25% (n = 42) and anticonvulsant in 11.9 % (n = 20) of the patients. Drug hypersensitivity reactions were immediate in 74.4 % (n = 125) and delayed in 25.6 % (n = 43) of the patients. Seventy-five patients (44.6 %) had at least one allergic disease, most commonly rhinitis (27.3 %, n = 46) or asthma (25 %, n = 42). Fifty-five patients underwent skin prick tests with aeroallergens, producing a positive result in 60% (n = 31). The prevalence of allergic disease was not differing according to the culprit drug. The frequency of developing at least one concomitant allergic disease was 47.2% (n = 50/106) for antibiotic hypersensitivity, 52.4% (n = 22/42) for NSAID hypersensitivity, and 15% (n = 3/20) for anticonvulsant hypersensitivity (p < 0.00).Immediate drug hypersensitivity reactions were more frequent in children who had allergic diseases (80 % vs. 64.5 %; p = 0.027). Conclusion: Nearly half (44.6%) of the children with proven drug hypersensitivity had concomitant allergic diseases and immediate reactions were more common in this group. Children evaluated for drug hypersensitivity should be assessed for other allergic diseases.

Introduction: There are limited data regarding the characteristics and management of drug hypersensitivity reactions (DHR) in hospitalized children. This study aims to determine the prevalence, clinical features, and management of DHRs in pediatric inpatients. Methods: Children who had pediatric allergy consultation for suspected DHR during hospitalization in Ankara Bilkent City Hospital between August 1, 2020, and July 30, 2021, were included. Patient and reaction characteristics, culprit drugs, and management strategies were recorded. When possible, diagnostic tests (skin or provocation tests) were performed after discharge. Results: Among the 14,090 hospitalized children, 165 (72% male, median age: 106 months) underwent consultation for 192 suspected DHRs with 246 drugs. Cutaneous eruptions were the most common (94.3%). There was anaphylaxis in 40 patients and severe cutaneous adverse drug reaction in 4 patients (drug rash with eosinophilia and systemic symptoms in 3, acute generalized exanthematous pustulosis in 1). Antimicrobials were the leading cause (78.4%, n = 193/246). In 48 reactions, 60 (24%) culprit drugs could be readministered with close follow-up or desensitization (n = 12). In total, 186 suspected drugs were discontinued, and 115 were replaced with alternative drugs. After discharge, 38 provocation tests (2 positives) and 36 skin tests (1 positive prick test, 1 positive intradermal test, and 1 positive patch test) were performed. Discussion/conclusions: The incidence of suspected DHR among pediatric inpatients was approximately 1.1%. Skin symptoms were the most common manifestation. Twenty-four percent of suspected drugs could be continued during hospitalization. Patients with DHR during hospitalization should be evaluated with a drug allergy work-up unless there are contraindications to testing.
ABSTRACT
BACKGROUND: Diet may contribute to better asthma control in children by impacting the immune and inflammatory pathophysiology. Therefore, this study aimed to investigate differences in nutrient intake, Children's Dietary Inflammatory Index (C-DII), and dietary quality according to asthma severity. MATERIALS AND METHODS: Asthma severity, dietary inflammatory status, and diet quality were assessed in a sample of 202 children with asthma (55.6% males, aged 5-18 years) attending a pediatric allergy outpatient clinic. Asthma severity was evaluated according to the Global Initiative for Asthma criteria and categorized as mild, moderate, or severe. The Children's Dietary Inflammatory Index (C-DII) and Healthy Eating Index (HEI-2010) were calculated based on information collected by the 24-h dietary recall method. Dietary quality was categorized as poor, moderate, or good diet according to HEI-2010. RESULTS: The mean age of the participants was 9.6 ± 3.2 years. Children with severe asthma were younger on average (p < 0.05). Children with mild asthma had significantly higher fiber and iron intake than those with moderate asthma (p < 0.05). C-DII values did not differ significantly according to asthma severity (p > 0.05). Dietary quality was evaluated as moderate in 89.1% of the participants and also showed no difference based on asthma severity. CONCLUSIONS: These findings suggest that inflammatory status and diet quality may not affect asthma severity in children, highlighting the influence of various genetic and environmental factors on the association between diet and asthma severity. More comprehensive and longitudinal studies are needed to investigate the mechanisms linking diet and asthma.

Background: Seeds are widely consumed as a traditional snack and have rich contents beneficial to health. With an increase in consumption rates, allergic reactions occur more frequently. We focus on multiple seed consumption related to recurrent anaphylaxis in this case. Case Presentation: We evaluated an 11-year-old boy with recurrent anaphylaxis. According to his medical records, he had been hospitalized several times, diagnosed with anaphylaxis, and treated. The family noticed direct (eating) or indirect contact with pumpkin seeds. In addition, the family mentioned another anaphylactic episode after watermelon seed and poppy seed bread consumption. We conducted skin prick-to-prick tests, examined total immunoglobulin E levels, and prescribed the treatment with an adrenalin autoinjector and preventive dietary recommendations. Conclusion: Anaphylaxis, particularly recurrent ones, should be evaluated with detailed anamnesis and supported with laboratory tests. Although seeds are beneficial and highly nutritious, it is necessary to consider them a source of allergens.

Background: The drug provocation test (DPT) and the oral food challenge (OFC) are considered as the criterion standard for the diagnosis of drug hypersensitivity reactions and food allergy. Severe allergic reactions may develop during these tests. Objective: To evaluate the frequency and features of anaphylaxis in pediatric patients undergoing OFCs and DPTs. Method: OFCs and DPTs performed in an open method in the pediatric allergy clinic of our institution between January 2014 and January 2021 were reviewed retrospectively. The characteristics of anaphylaxis that developed during these tests were evaluated. Results: A total of 3631 OFCs and/or DPTs were performed on 2588 pediatric patients. Reactions were recorded in 317 challenges (8.7%), including 42 (1.2%) in the form of anaphylaxis. Of the patients with anaphylaxis, 31 developed anaphylaxis during OFC and 11 during DPT. Anaphylaxis during OFCs was mostly triggered by yogurt (n = 8), hen's egg (n = 6), baked milk (n = 5), and baked egg (n = 4). Cases with anaphylaxis during DPT were recorded mostly with ibuprofen (54.5% [n = 6]). All patients who developed anaphylaxis during OFC had cutaneous manifestations, and 90.3% had respiratory symptoms. Gastrointestinal involvement was present in 32.3% of the patients. During DPT, cutaneous manifestations were observed in 90.9% in the patients who developed anaphylaxis and the respiratory tract was involved in 81.8%. In terms of concomitant allergic diseases, 51.6% of the patients who developed anaphylaxis during OFC had atopic dermatitis and 38.7% had asthma. All the patients with anaphylaxis triggered by nonsteroidal anti-inflammatory drug DPT had asthma. Of the anaphylaxis, 54.8% were mild, 35.7% were moderate, and 9.5% were severe. Severe anaphylaxis was recorded with baked milk (n = 2), baked egg and trimethoprim-sulfamethoxazole (n = 1, each). The patients did not require intensive care, and no death occurred. Conclusion: Anaphylaxis may develop during OFCs and DPTs. These tests should be carried out by experienced allergists in an appropriate setting where emergency equipment and medications, including epinephrine, are readily available.

Background: Drug provocation tests (DPTs) are the gold standard for the diagnosis of drug hypersensitivity reaction (DHR). To the best of our knowledge, there is no previous study reporting DPT-related anxiety levels in children and their parents. This study aimed to determine the difference in pre- and post-DPT anxiety levels of parents and children who were informed of the possibility of another DHR during the DPT, and to evaluate the relationship between parental psychological distress and anxiety levels. Methods: The study included children who underwent DPT in our clinic between July 1, 2019, and February 29, 2020, and accompanying parents who consented to participate. Age-appropriate State-Trait Anxiety Inventory scales were used to assess levels of state and trait anxiety in the patients and parents. The Symptom Checklist-90-Revised (SCL-90-R) was used to screen for psychological symptoms in parents. Results: Data were collected from the parents of 69 children who underwent DPTs. The patients' median age was 7.28 (interquartile range: 4.52-10.06) and their parents' mean age was 35.28 ± 5.38 years. Anxiety-related data were collected from 21 pediatric patients. The children and parents had higher state anxiety scores before DPT compared to after DPT. There was a positive correlation between the parents' trait anxiety and pre-DPT state anxiety scores. In addition, parental pre-DPT state anxiety scores were positively correlated with SCL-90-R general severity index, somatization, anxiety, obsessive-compulsive, and depression subscale scores. Conclusion: The risk of allergic reaction in DPT may cause anxiety. A high level of parental anxiety before DPT, which gradually decreased after negative test results, was associated with history of drug-induced anaphylaxis in their children and high trait anxiety. Appropriate evaluation of patients and parents before DPT and providing detailed information may be important to reduce this anxiety.

Background: Food allergies are known to resolve over time, but there is little information on the natural history of food-induced anaphylaxis (FIA). Objective: This study aimed to evaluate the natural history of FIA in children and determine the factors that affect prognosis. Methods: Children with FIA who were followed up for at least 3 years, between 2010 and 2020, were included. Patients' families were contacted by telephone to question their child's tolerance status and invite them for reevaluation if uncertain. The patients were grouped as tolerant or persistent according to parent reports or reevaluation results. Logistic regression analysis was performed to determine the factors that affected persistence. Results: The study included 185 patients (62.2% boys) with 243 anaphylactic reactions to various foods. Fifty-eight patients (31%) gained tolerance within a 3-year follow-up period. Tolerance rates were higher in patients with FIA to milk (40%) and egg (43.9%) compared with to tree nuts (18.8%), legumes (5.6%), and/or seafood (11.1%) (p < 0.001). In a multivariate analysis, risk factors for persistent FIA were multiple food anaphylaxis (odds ratio [OR] 3.755 [95% confidence interval {CI}, 1.134-12.431]; p = 0.030), total IgE > 100 kU/L (OR 5.786 [95% CI, 2.065-16.207]; p = 0.001), and skin-prick test wheal size > 10 mm (OR 4.569 [95% CI, 1.395-14.964]; p = 0 .012) at presentation. Conclusion: Approximately a third of the patients with FIA developed tolerance within 3 years. Clinicians should remember that children with food allergies, even anaphylaxis, may develop tolerance over time. Regular follow up and reevaluation of tolerance status are necessary to avoid unnecessary elimination.

INTRODUCTION: Anaphylaxis is a severe, potentially fatal systemic hypersensitivity reaction with an acute onset. Etiology, clinical presentation, risk factors, comorbidities of pediatric anaphylaxis may vary depending on the age of the child. OBJECTIVE: The aim of this study was to investigate the etiology, clinical features, management of anaphylaxis in infants, preschoolers, school-age children, and adolescents. METHODS: The patients presenting with anaphylaxis between January 2015 and December 2018 in a single pediatric tertiary hospital were evaluated retrospectively. Demographic data, the triggers, sign-symptoms, severity, and the management of anaphylaxis were recorded. RESULTS: 239 patients were included in the study, 62.3% of whom were boys. The median age was 6.7 (IQR 2.33-12.83) years. 23.8% of the patients were infants, 15.5% were preschoolers, 33.5% were school-age children, and 27.2% were adolescents. Anaphylaxis mostly occurred at home. The most common causative agents were foods (39.3%), drugs (30.1%), and venoms (15.9%) of all cases. Main food allergens were cow's milk and hen's eggs in infants, cow's milk and tree nuts in preschoolers, and tree nuts and legumes in school-age children. Cases of drug-induced anaphylaxis (DIA) were recorded mostly with antibiotics (40.3%), followed by NSAIDs (23.6%). The primary trigger of anaphylaxis was foods in infants and preschoolers and drugs in school-age children and adolescents. There was no difference between age groups in terms of the system involved and severity. Severe anaphylaxis was more common with DIA. Adrenaline was used in 69.8% of all cases with no significant difference between age groups. CONCLUSION: Etiology and symptoms of anaphylaxis may differ between age groups. Raising awareness, educating patients and their parents on anaphylaxis and its management is essential.

INTRODUCTION: There are a limited number of studies about the clinical findings of coronavirus infection in pediatric patients with asthma. We aimed to evaluate the clinical and laboratory characteristics of pediatric patients with asthma and healthy children without chronic disease who infected with SARS-CoV-2. METHODS: This is a retrospective, case-control study comparing the asthma diagnosed and healthy children who were diagnosed as COVID-19 in our hospital between March 11 and November 10, 2020. RESULTS: During the study period, 6,205 children were diagnosed with CO-VID-19 in our hospital. Only 54 (0.87%) patients had a diagnosis of asthma. The mean of the age was 10.5 years and 53.7% (n:29) of the patients with asthma were male. Cough, shortness of breath, emesis, and diarrhea were found to be significantly higher in asthma group than in the control group (respectively p = 0.002, 0.000, 0.002, 0.019, 0.015). Patients who were given SABA was significantly higher in asthma diagnosed patients (p = 0.000). Hospitalization was significantly higher in asthma group (p = 0.025), and the duration of hospitalization was significantly higher in control group (p = 0.034). There was no significant difference between the 2 groups in terms of requiring oxygen treatment and in laboratory findings between groups. CONCLUSION: This study revealed that pediatric patients diagnosed with asthma were in a mild clinic. According to these findings, asthma may not affect the course of the COVID-19 in children.

Allergic transfusion reactions (ATRs)are a common form of acute transfusion reaction. It was aimed to determine the clinical characteristics and frequency of ATRs in children. This study included children who were transfused with red cell concentrate (RCC), fresh-frozen plasma (FFP), platelet concentrates(PC), apheresis granulocyte, and cryoprecipitate.The patients' sociodemographic characteristics, the blood product that caused the reaction, the type and timing of the reaction, the patient's age at time of reaction and their diagnosis, follow-up period, and clinical data were recorded. A total of 89703 bags of blood products were transfused to 4193 children.Two hundred eleven acute transfusion-related reactions occurred in 157 (3.74%) patients.Of these, 125 reactions (59%) were allergic. ATR occurred in 125 of 89703 infusions (0.14%).The median age of patients was 9.99 years (IQR:4.67-14.38) and ATRs occurred at a median of 30 minutes into the transfusion. Eighteen (18%) of the patients also had a history of drug reaction.When the blood products that caused ATRs were examined, 43(34.5%) occurred with apheresis and single-donor PC, 37(29.6%) with FFP, 32 (25.6%) with RCC, 10(8%) with pooled PC, 2(1.6%) with cryoprecipitate, 1(0.8%) with apheresis granulocyte.Ninety-nine(79%) of the reactions were minor allergic reactions and 26(21%) were anaphylaxis.Compared to minor allergic reactions, the proportion of PCs was statistically higher in anaphylaxis(p=0.02). Patients receiving PC should be monitored more carefully during the first half hour of transfusion. In addition, approximately one-fifth of the patients who developed ATR also had a history of drug reaction. Patients with previous reactions to drugs may be more likely to have ATR.

Introduction: Limited data are available on recurrent anaphylaxis in childhood. Delayed adrenaline administration is the major cause of deaths due to anaphylaxis. As well as prescribing the adrenaline autoinjector (AAI), it is important to make sure that the patient carries the device at all times and uses it correctly for the appropriate indication. Objective: The aim of our study was to evaluate the recurrence of anaphylaxis and AAI use in childhood. Methods: Pediatric patients who were evaluated for anaphylaxis and prescribed AAI between January 2015 and December 2018, in the pediatric allergy and immunology clinic of our hospital were screened retrospectively. A telephone-based survey was conducted with the parents of the patients to investigate the recurrence of anaphylaxis in patients and the use of AAI by their parents for the management of anaphylaxis. Results: A total of 148 patients (64.9% boys) were prescribed an AAI for anaphylaxis. The telephone survey could be conducted with 111 parents (75%) with an AAI prescription. Of these patients, 23.4% (n = 26) of the parents reported that their children experienced recurrent episodes of anaphylaxis. In the recurrent anaphylaxis cases, the triggers were foods in 77%, venoms in 11.5%, drugs in 3.8%, and idiopathic anaphylaxis in 7.7% of the patients. AAI use at the time of anaphylaxis was reported by 42.3% of the parents. The reasons cited by the parents for not using AAI during an episode of anaphylaxis included the preference to have adrenaline administered at a health care facility because of its proximity (60%), fear of using the device (13.3%), hesitation (6.7%), not having the device with them (13.3%), and unavailability of the device (6.7%). Conclusion: Educating the patients and families about the importance of using AAI is crucial, and training on how to use the device should be repeated at each clinic visit and every opportunity.

BACKGROUND/OBJECTIVES: Adverse reactions to local anesthetics are relatively common, but proven IgE-mediated allergy is extremely rare. We aimed to determine the frequency of local anesthetic allergy in pediatric patients. PATIENTS AND METHODS: The medical records of 73 patients who presented to our clinic with a history of suspected allergic reaction to local anesthetics and underwent diagnostic testing between 2012 and 2020 were retrospectively analyzed. Diagnoses were based on case histories, skin tests, and subcutaneous challenge tests. RESULTS: A total of 75 test series were carried out on the 73 patients (43 boys; median [IQR] age 9.25 [7.26-14.25] years, range 3-17.8 years). The most commonly tested drugs were lidocaine (n = 38; 50.6%) and prilocaine (n = 15; 20%). Local anesthetic allergy was confirmed in one (1.3%) of the 73 patients by positive subcutaneous challenge test with mepivacaine. CONCLUSION: There are limited data in the current literature regarding local anesthetic allergies and diagnosis test results in pediatric patients. Proven local anesthetic allergy is less common than expected by society and physicians, and therefore diagnostic tests are needed for patients with no contra-indications such as severe or life-threatening reactions.

Background: Patch tests are used to diagnose nonimmediate T-cell-mediated drug hypersensitivity reactions. The aim of this study was to evaluate the results of patch tests performed with suspect drugs in children. Methods: Patients < 18 years of age who had a drug patch test at the pediatric allergy outpatient clinic of our hospital between January 2014 and January 2020 were included in the study. Age, sex, culprit drug(s), reaction characteristics, and patch test results were recorded from the patients' files. Results: A total of 105 drug patch tests were performed on 71 patients during the study period. The patients' median age was 7 years (interquartile range, 4-11 years), and 57.7% (n = 41) were boys. Twenty-three patients (32.3%) had severe cutaneous adverse reaction (Stevens-Johnson syndrome in 11, drug reaction with eosinophilia and systemic symptoms in 9, and acute generalized exanthematous pustulosis in 3 patients), 45 (63.3%) had maculopapular rashes, and 3 (4.2%) had fixed drug eruption. A total of 20 patch test results (28%) were positive: 18 of 44 patch tests (40.9%) with antiepileptic drugs and 2 of 48 patch tests (4.1%) with antibiotics. Positive results were obtained in 23% of the patch tests (6/26) in 20 patients with severe cutaneous adverse reactions and in 17.7% of the patch tests (14/79) in 51 patients with mild cutaneous reactions. No adverse reactions occurred during or after the patch tests. Conclusion: In our study, patch test positivity was more common with antiepileptic drugs and in patients with severe cutaneous drug reaction.

INTRODUCTION: Beta-lactams (BLs) are one of the most frequent causes of drug hypersensitivity reactions (HRs), and cephalosporins are a widely used subclass of BLs, especially in children. The aim of this study was to evaluate the clinical features and diagnostic test results of pediatric patients evaluated for suspected cephalosporin allergy. METHODS: This study included patients who presented to our pediatric allergy clinic with a history of reactions attributed to cephalosporins between January 1, 2011, and December 31, 2019, and whose diagnostic tests were completed for the diagnosis. RESULTS: This study included 120 pediatric patients and 69 (57.5%) of them were girls. The median age was 38.63 (interquartile range 10.5-85.7) months. Reactions occurring within 1 h of drug intake were reported in 33 patients (27.5%). Reactions were maculopapular rash in 55 (45.8%) patients, urticaria and/or angioedema in 49 (40.8%), anaphylaxis in 11 (9.2%), severe cutaneous drug reaction in 4 (3.3%), and fixed drug reaction in 1 patient (0.83%). The most frequently suspected agent was cefixime in 41 patients (34.2%). In total, 30 (25%) patients were diagnosed as having cephalosporin hypersensitivity. Confirmation of HRs was also significantly more frequent among patients who were older (p: 0.000), who had taken the drug parenterally (p: 0.000) and with immediate reactions (p: 0.000). CONCLUSION: Cephalosporin allergy has been confirmed in approximately one-fourth of the patients evaluated for suspected cephalosporin allergy. Confirmation of HRs was significantly more common among patients who were older, had immediate reactions, and had taken the drug parenterally.

BACKGROUND: Currently, there are no reliable clinical tools available for predicting asthma in pre-school-aged children with recurrent wheezing. The aim of this study was to evaluate the usefulness of serum periostin, YKL-40, and osteopontin biomarkers in wheezy pre-school-aged children for predicting the development of asthma in school ages. METHODS: The study was prospectively conducted between 2011 and 2017. The clinical features of the pre-school-aged children with recurrent wheezing and the levels of serum periostin, YKL-40, and osteopontin were measured. The same participants were reevaluated in school-age period, and participants with asthma were identified. Relative risk (RR) for the development of asthma was analyzed. RESULTS: Of the 197 pre-school-aged children with recurrent wheezing who were reevaluated in school-age years, 32% of them had asthma. Serum periostin, YKL-40, and osteopontin levels at admission could not predict participants who would have asthma symptoms in school-age years. The RR for continuing of asthma symptoms was higher in participants who had their first wheezing episode before 1 year of age, preterm birth, cesarean section delivery, prenatal smoking exposure, multi-trigger wheezing, parental asthma, modified asthma predictive index positivity, prophylactic vitamin D intake ≤ 12 months, breastfeeding time ≤ 12 month, and aeroallergen sensitivity [RR (95% CI) and P value: 2.813 (1.299-6.091), 0.002; 1.972 (1.274-3.052), 0.009; 1.929 (1.195-3.114), 0.004; 2.232 (1.463-3.406), <0.001; 3.152 (1.949-5.097), <0.001; 1.730 (1.144-2.615), 0.016; 2.427 (1.559-3.777), <0.001; 2.955 (1.558-5.604), <0.001; 1.767 (1.084-2.881), 0.016; 0.765 (0.556-1.053), 0.016; respectively]. CONCLUSION: Results have shown that clinical features were more valuable than biomarkers in predicting having asthma in school-age years in participants who had recurrent wheezing in pre-school-age period.
