Long-acting insulin allergy in a diabetic child

Insulin allergy has been uncommon since the introduction of human recombinant insulin preparations; the prevalence is 2.4%. Insulin injection could elicit immediate reactions, which are usually induced by an IgE-mediated mechanism, within the first hour after drug administration. In the present study, we describe the case of a child who experienced immediate urticaria after long-acting insulin injection. A 9-year-old girl affected by type I diabetes mellitus referred a history of three episodes of urticaria 30 min after insulin subcutaneous injection. During the first week of insulin therapy, she developed generalized immediate urticaria twice after long-acting insulin glargine first and then once after insulin degludec administration. Symptoms resolved within a few hours after treatment with oral antihistamine. She tolerated rapid insulin lispro. Her personal allergological history was negative. Skin prick tests with degludec, glargine and detemir were performed, showing negative results. Intradermal 1:100000-diluted tests were immediately positive for both degludec and glargine but not for detemir. In light of these findings, detemir was administered without any reaction. Our results show that detemir is tolerated by patients with clinical hypersensitivity reactions to degludec and glargine. Although reactions could be attributable to additives allergy, such as zinc or metacresol, this was excluded since all three preparations contain the same components. So, insulin itself acted as offending allergen. Detemir differs from degludec and glargine in a few aminoacids. Therefore, it is possible that the conformational rather than the linear epitope may be responsible for the reaction. This result suggests integrating intradermal tests in the diagnostic flowchart for insulin allergy. Insulin allergy should always be suspected in patients with immediate symptoms after drug injection. As allergologic work-up, prick by prick test and intradermal test to insulin preparations should be performed. In case of negative results of cutaneous tests, insulin analogs may be administered

Knowledge, attitudes and misconceptions of Italian healthcare professionals regarding fever management in children

Abstract Background Fever phobia is still a major issue in paediatrics. We report knowledge of a sample of Italian paediatricians performed six years after the release of the Italian guidelines for the management of fever in children (IFG). Methods A questionnaire, developed following the IFG recommendations and previously administered to 300 paediatricians in 2012, was proposed to all the paediatricians attending the 2015 National Congress of Practice Paediatrics, held in Florence, Italy. Changes in answers over time were analyzed. Results 70.2% (562/800) paediatricians returned the questionnaire. The recommended site and device for body temperature measurement in children > 1 year was correctly chosen by 89.3% of participants (vs. 80.7% of 2012 participants; P < 0.001), but with children aged less than 1 year the correct answer was selected only by the 50.3% (vs. 39.3% of 2012 participants: P < 0.001). Use of physical methods was still incorrectly recommended by 51.6% of paediatricians (vs. 63.6% in 2012; P < 0.001). Use of antipyretics according to discomfort was adopted only by 38.2% of participants, while 12.2% of them recommended alternate use of antipyretics. These proportions were substantially stable since 2012 (45 and 11% respectively), rectal administration of antipyretics only in case of vomiting was correctly recommended by 86.8% of paediatricians vs. 74.7% in 2012 (P < 0.001). Conclusion Improvements in some pediatricians’ misconceptions were observed over time. However, some incorrect habits persist. Further studies are needed to better understand the “weak points” of the communication between Scientific Societies and paediatricians in order to impact everyday clinical practice

Effectiveness of a tailored medical support to overcome the barriers to education, treatment and good metabolic control in children with type-1 diabetes from ethnic minorities

To analyze the effectiveness of a tailored medical support to help children from ethnic minorities to achieve the same good metabolic control of autochthonous peers with type-1 diabetes (T1D)

Sulfonylurea-responsive neonatal diabetes mellitus diagnosed through molecular genetics in two children and in one adult after a long period of insulin treatment

A permanent neonatal diabetes mellitus has finally been diagnosed through molecular genetics in two children and one adult after 9 to 35 years of uninterrupted insulin treatment. These patients developed diabetes before 6 months of age and were autoantibody negative. In one boy, a mutation in the KCNJ11 gene was identified at 9 years of age. In the other two patients (daughter and father, 12.6 and 25 years old respectively) the new gene variant (ABCC8/L213P) was found. Switching from insulin to sulfonylurea treatment leads to the definitive discontinuance of insulin therapy, improving metabolic control as well as the amelioration of the associated neurodevelopmental disabilities in the young girl in which an intermediate Development Delay, Epilepsy, Neonatal Diabetes syndrome was diagnosed
