Background Anaphylaxis is a serious and potentially lethal systemic reaction affecting more than one organ or system. Objective We aimed to describe the demographic characteristics, clinical features, causes, settings, and administered therapy in Turkish children. Methods This retrospective, case note study included all children referred to the outpatient clinics of the Pediatric Allergy Departments of the participating study centres from 1 July 1999 to 30 June 2009 for investigation of anaphylaxis or who were seen by us at the moment of the reaction during the same period and who met the clinical criteria of anaphylaxis. Results Two hundred and twenty-four cases of anaphylaxis were reported in 137 children (88 boys, P = 0.0001). The mean +/- SD age at the referral was 7.7 +/- 4.2 years (range: 4 months-17 years). Ninety-eight episodes (43.8%) occurred at home. The symptoms were cutaneous in 222 (99.1%) episodes, respiratory in 217 (96.9%), neuro-psychiatric in 118 (52.7%), cardiovascular in 92 (41.1%), and gastrointestinal in 88 (39.3%). Biphasic reaction was reported in seven episodes (3.1%, 95% CI: 1.5-6.3). Death occurred in one case (0.4%, 95% CI: 0.08-2.4). Treatment was available in 158 episodes (70.5%). Of them, 148 (93.7%) received antihistamines, 132 (83.5%) corticosteroids, 51 (32.3%) epinephrine, and 17 (10.8%) beta-2-mimetics. The causative agents were foods in 86 (38.4%) episodes, hymenoptera venom in 84 (37.5%), drugs and medications in 47 (21.0%), and latex in 5 (2.2%). In two episodes (0.9%), the causative agent was unidentified. Allergy to the trigger was known prior to anaphylaxis in 116 (51.8%) episodes. An epinephrine autoinjector had been prescribed for 70 children (51.1%). Conclusions and Clinical Relevance Anaphylaxis was seen significantly more in boys. Most of the reactions occurred at home. Foods were the most frequent cause. Epinephrine, the first-line treatment of anaphylaxis, was administered in only a third of the children.

Background: Childhood atopic dermatitis (AD) is classically accepted as initial finding of atopic march; however, non-atopic cases do not follow this course. The aim of this study was to determine the characteristics and prognosis of AD in childhood in Turkey. Methods: The study included 531 children with AD that presented to pediatric allergy departments in 11 different regions of Turkey. Age at diagnosis, total serum and inhalant-specific immunoglobulin E (IgE) levels and allergen skin prick test results were recorded retrospectively. Clinical characteristics like additional allergic diseases at presentation or during follow-up were recorded as well as duration of follow-up. Results: Mean age at diagnosis was 37.8 +/- 36.2 months. Mean IgE level was 318.3 +/- 677.8 IU/ml (median 100 IU/ml). Skin prick tests yielded positive results in 47% of children. At presentation, 31.6% of children reported additional allergic disease, while 11.7% developed allergic disease during follow-up. Among all, 46.6% had additional allergic disease at any point. IgE levels were significantly higher in children with additional allergic diseases (p = 0.001). Allergen skin prick test positivity and family history of allergic diseases increased the risk of additional allergic diseases significantly (OR = 3.90, 95% CI = 2.3-6.6 and OR = 1.89, 95% CI = 1.3-2.8, respectively). Conclusions: Allergic sensitization is not present in all cases of AD. Coexistence of additional allergic diseases is not as high as expected but more common in children who have been demonstrated to have atopic sensitization with high IgE levels and allergen skin prick test positivity.

Background. The Childhood Asthma Control Test (C-ACT) has been proposed to be a simple, patient-based test that is able to reflect the multidimensional nature of asthma control. In this analysis, the aim was to evaluate the perceptions of physicians and caregivers concerning C-ACT and its predictive value for future asthma-related events. Method. In a multicenter prospective design, 368 children aged 4-11 years with asthma who were either well-or not well-controlled were included in the study. The study participants were evaluated during three visits made at 2-month intervals and the Turkish version of C-ACT was completed each month. Parents completed questionnaires concerning their perception of asthma (before and after the study) and the C-ACT (after the study). Physicians completed a survey about their perception of a control-based approach and the C-ACT. Results. The C-ACT scores increased from visit 1 to visit 3, with improvement seen in all domains of the test. At the end of the study period, the parents more strongly agreed that asthma could be controlled completely and that asthma attacks and nocturnal awakenings due to asthma were preventable (p < .05). Most of the parents reported that the C-ACT helped them to determine asthma treatment goals for their children and also that the C-ACT improved communication with their physicians. The physicians indicated that a control-centered approach was more convenient (95%) and simpler (94.5%) thana severity-centered approach and provided better disease control (93.4%). A higher C-ACT score was associated with a decreased risk of asthma attack and emergency department admittance in the 2 months following the administration of C-ACT. Conclusion. Our findings indicated that the C-ACT improved both parental outlook on asthma control and the communication between the physician and parents. There was a good correlation between the C-ACT score and the level of asthma control achieved, as described by the physician. Additionally the C-ACT score was predictive of future asthma-related events. These findings suggest that the C-ACT may have an important role in asthma management in the future.

Introduction: The reliability and validity of Turkish version of Childhood Asthma Control Test (C-ACT). Purpose: The management of asthma is an important as well as difficult issue of physician's daily practice particularly in busy clinical settings. C-ACT was created to identify asthma control levels in children aged 4-11 years. Our aim was to evaluate the reliability, validity and responsiveness of C-ACT in a Turkish sample of children with asthma. Method: In this multicenter study, 368 children were enrolled. C-ACT was completed every month by parents and patients who were evaluated in 3 visits within 2 month intervals. At each visit, physicians interpret the control level and decided for the treatment step as established in GINA guidelines. Results: The internal consistency reliability of the Turkish version of C-ACT (C-ACT1 to C-ACT5) was found to be 0.82, 0.83, 0.82, 0.82 and 0.80, respectively (reliability statistics, Cronbach's alpha). Test-retest reliability was 0.71. There was significant correlation between C-ACT and physician's assessment of asthma control at visit 1 (r = 0.65, P < 0.001). Conclusions: Turkish version of C-ACT is an accurate and reliable tool to evaluate asthma control in children aged 4-11 years. Its widespread use may facilitate appropriate assessment of asthma control and may lead to decrease the number of uncontrolled patients.
