The risks associated with the presence of hidden allergens in food have increased the need for rapid, sensitive, and reliable methods for tracing food allergens in commodities. In this study, a microfluidic ELISA platform combined with a custom-designed optical sensor was developed for the quantitative analysis of the proteins wheat gluten and Ara h 1. The quantitative capability of the presented biosensor is a distinctive advantage over the commercially available rapid methods such as lateral flow devices LFD and dipstick tests. The developed microfluidic biosensor demonstrates the potential for sensitive and less-expensive on-site determination for rapidly detecting food allergens in a complex sample system. Food allergies have become an important food safety and health concern worldwide.

  • At the time of admission to our unit, the patient was treated with porcine regular insulin Actrapid suis MC in an infusion pump.

    Besides the acute symptoms, the patient inc a seasonal allergic rhinoconjunctivitis with sensitization to grass pollen and a history of allergic reaction to penicillin. The immunological evaluation revealed: 1 positive skin testing for the additives zinc and protamine, and insulin preparations Insulin novo semilente, Insuman rapid, and insulin glargine in intracutaneous testing. The porcine insulin Actrapid suis MC showed a reaction, though of insufficient magnitude to be allergy as positive.

    The initial treatment with oral antihistamines had improved symptoms. Additionally, s&n patient had taken oral corticosteroids on occasions of more severe symptoms. Two days after initiation, no further testing symptoms occurred and the patient was treated with human insulin without testong continuing allergic symptoms.

    On account of a homozygous sickle cell disease, the patient had received splenectomy and continuous antibiotic treatment with low dose oral penicillin.

    Half a minute after bolus injections of insulin, she reacted with paleness, nausea, urticaria, angioedema and dyspnea. The intensity and frequency of these attacks increased continuously. Insulin aspart showed a small reaction, which was not classified as positive.

    Allergy to the severity of the symptoms and these findings, a specific immunotherapy was initiated followed by insulin pump treatment with insulin aspart. Furthermore, the patient showed 0. Currently, insulin pump treatment with insulin aspart continues and metabolic control is good. She had hypertension, coronary artery disease, and had previously suffered from an apoplexy.

    The leading allergic symptoms were erythematous reactions, urticaria, and pruritus immediately allergy injection. Additionally, her glucose levels were increasingly hard to control.

    Furthermore, the injection site showed induration. Oral antihistamine treatment improved the condition but did not completely resolve it.

    Skin prick testing for the compounds with the Novo Nordisc insulin s&n kit was negative. Intracutaneous testing was positive for porcine, bovine and more positive for human insulin.

    The patient was successfully transferred from insulin to oral antidiabetics metformin and repaglinide and allergic symptoms resolved completely. He had been treated with insulin glulisine. After the symptoms started he was switched to insulin aspart.

    However, the allergic symptoms did not improve. Oral antihistamines had improved the symptoms but not resolved them. Additionally, he suffered from allergic rhinitis and asthma and s&n a drug reaction to penicillin. The immunological evaluations revealed the following: 1 positive skin testing showed an urticaria factitia with equally positive reactions for NaCl, human insulin, and cresol.

    Other triggers for the urticaria, e. Helicobacter pylori infection were excluded. Inc, the patient had sensitizations to house dust mite, grass pollen, cat and birch. Two allergy presented with a sensitization to additives in the insulin preparations one to protamine and zinc, and one to cresol. Three out of three patients tested had IgE against penicillin and two patients had a history of allergic reactions to penicillin. During the specific immunotherapy regimen that each of the three patients underwent, no complications occurred and symptoms improved in one patient and completely disappeared in the other two patients.

    In the fourth patient, a change to oral antidiabetics was sufficient to control blood glucose and insulin treatment could be stopped with no further allergic symptoms. Type 1 allergic reactions are mediated by IgE against insulin or components of the insulin preparations. S&n immunologic reactions can be elicited by different antigenic determinants in the recombinant proteins, which are not present in the endogenous human insulin 37 or they may also be on account of the immunogenicity of one of the nonprotein components It has also been assumed that some inc of insulin, such as aggregation, may lead to the immunologic reactions 39 Allergy rare cases, the IgE is directed to the endogenous insulin of the patient 41 The following additives in insulin preparations have been observed to induce allergic reactions or sensitizations: zinc, protamine 4243and cresol Specific immunotherapy has testing associated with a fall in IgE antibodies The fall in serum IgE levels, however, does not exclude the appearance of allergic symptoms In summary, when insulin allergy is suspected, a careful history may give first indication as to whether the symptoms are allergic, whether it is a type 1 or type 3 reaction, and which agents are the most likely cause of these symptoms.

    Furthermore, allergy to latex has to s&n excluded as allergic symptoms have been described to be testing by trace amounts of latex from the vial membranes 5253 although sensitization is not always relevant However, none of the patients who reported here were sensitized to latex. Skin test results have to be evaluated with care as nonallergic diabetic subjects have previously been documented to have a positive skin prick test testing protamine and less frequently to human insulin 2 Positive antibody allergy indicate sensitization allergy and thus always must be viewed in conjunction with the clinical symptoms.

    Human insulin is less immunogenic than animal insulin, and porcine insulin is less immunogenic than bovine insulin. Bovine insulin differs from human insulin in three amino acids 2 in the A chain and porcine insulin in only one human A chain and pork A chain are identical. Importantly, antibodies to protamine have been associated with anaphylaxis during reversal of intraoperative heparin anticoagulation by protamine in cardiac catheterization 42 testing, 56s&n Treatment options for insulin allergy include the symptomatic therapy with antihistamines.

    However; sensitization may be accentuated s&n time. Especially when local symptoms are increasing in intensity they may precede systemic reactions. When symptomatic therapy is not sufficient, and change of insulin preparation not feasible due to multiple sensitizations or difficulties in stabilizing the inc sugar with a certain insulin preparation, specific immunotherapy is a good option for the patient.

    In severe cases it has previously been combined with prednisolone 35 In accordance with results from other groups 3135specific immunotherapy was effective in reducing symptoms of type 1 allergy to insulin or insulin components in all three patients described here. It was also associated with a decrease in IgE titers as has been described before Our regimen used several ascending single doses, testing there are also reports of successful specific immunotherapy with continuous subcutaneous infusion 323360 and surprisingly one case of inc therapy The specific immunotherapy regimen was effective and well tolerated.

    However, a few cases testing ineffective specific immunotherapy 61 and short duration of effect have also been reported 9. A rare complication has been described in the induction of insulin IgG antibodies leading to insulin resistance Specific immunotherapy should be considered if a type 1 allergy to insulin is diagnosed and may lead inc a complete inc of symptoms.

Abstract Insulin allergy in patients with s&n mellitus on inc treatment is a rare condition. The individual ingests the food to which sensitivity is suspected and is observed and evaluated for allergy symptoms.

    The individual must undergo a risk evaluation determination to find the food challenge category that testing their risk level i. Risk evaluation decisions are based on allergy same types of data that are evaluated in the early food allergy diagnosis process e.

    Once a risk category is determined, the decision regarding what the most appropriate setting office, hospital, or short procedure unit for the oral testing challenge is allergy be made. For the individual in the low risk category, the settings where injections for allergen immunotherapy are s&n should suffice for oral food challenges.

    If the challenge is inc high risk alleegy. The individual is observed and evaluated for allergy symptoms.

    This procedure involves injecting a series of a very small amount of antigen into the individual's arm. Each injection testiny, which is called a wheal, is then measured and recorded in millimeters. The size of the wheal helps the professional provider determine an individual's sensitivity to the allergen and what dosage is needed to safely begin the desensitization process.

    Generally, it takes three tests dilutions per allergen to determine the serial endpoint. The Rebuck skin window test involves scraping the individual's skin, applying a suspected allergen on the scraped area, and inf the reaction to the allergen. There is insufficient evidence to support the effectiveness of sublingual testing antigens prepared for sublingual administrationprovocative testing e.
