β-Lactam antibiotics allergy is recognized as a public health concern. By covalently binding to serum proteins, penicillins are known to form immunogenic complexes. The latter are recognized and digested by antigen-presenting cells into drug-hapten peptides leading to the immunization of treated persons and IgE-mediated hypersensitivity reactions encompassing anaphylaxis. If type I allergic reactions to drugs are often unpredictable, they are known to be dependent on CD4+ T-cells. This fundamental study revisits the chemical basis of the benzylpenicillin (BP) allergy with the aim of identifying immunologically relevant biomimetic benzylpenicilloylated peptides through the analysis of BP-conjugated human serum albumin (BP-HSA) profile and the evaluation of the naïve CD4+ T-cell responses to candidate BP-HSA-derived peptides...

Although there are many reported cases of immediate allergy after ingestion of foods containing cochineal, there are few reports of allergic contact dermatitis from carmine. We present a rare case of allergic contact dermatitis due to carmine. A 52-year-old female presented with an itchy erythema on her cheeks at the site where blush had been applied. Patch-tested with her cosmetics, she showed a positive reaction to the blush (30% in petrolatum) and to 0.2% (but not 0.1%) carmine in petrolatum. In this case, the optimum patch-test concentration of carmine was 0...

BACKGROUND: Asthma and allergy are common chronic diseases caused by genetic and environmental factors. OBJECTIVE: To study the effect of different environments on the prevalence of both diseases in an isolated founder population that resettled in different geographic and environmental areas (namely, the genetically homogeneous population that immigrated to Israel from Cochin, India, 50 years ago). METHODS: Respiratory and allergy symptoms were recorded by a questionnaire...

Macrolide hypersensitivity is a rarely reported event. However, carmine dye has become increasingly important as a provocative agent. We present a case of a woman with documented carmine hypersensitivity, who reported anaphylaxis 90 minutes after ingestion of a generic azithromycin. Our investigations revealed that this was an allergy to the carmine dye in the tablet's coating rather than to the antibiotic. Seven extracts were prepared including carmine dye, crushed dried female cochineal insects, crushed tablets of Zithromax (Pfizer Inc...

BACKGROUND: Carmine is a natural red pigment obtained from dried gravid female cochineal insects (Dactylopius coccus or Coccus cacti). There have been several reports of allergies to carmine, but the major allergens responsible have not been identified. OBJECTIVE: To identify the major allergenic proteins in cochineal. METHODS: Immunoblots of purified cochineal extract were probed with sera from 3 patients with allergy. Partial amino acid sequences were determined for the proteins bound by IgE, and the corresponding cDNA, containing a complete coding region, was cloned by 5' and 3' rapid cDNA extension and PCR...

In the last ten years research in vaccinology has been developed in the world to conceive new vaccine approaches against infections like HIV/AIDS. Jean-Gérard Guillet is a pioneer in the development of new vaccine strategies. From the first results he obtained in the late 80's on the presentation of antigenic peptides to T cells, he axed his work on the study of induction mechanisms of T cell mediated immune responses. The selection of antigenic peptides and the search to enhance antigen immunogenicity led him to elaborate lipopeptides as new vaccine formulae...

We herein describe a 33-year-old female who recurrently exhibited urticaria accompanied by vomiting, diarrhea and dyspnea after taking red-colored food. From her history, we suspected the cochineal dye, the commonly used natural red dye in red-colored food and beverage, to be the cause of her symptoms. Oral provocation test using cochineal dye-stained red-colored boiled-fish-paste induced urticaria and respiratory symptoms. Furthermore the prick tests and the scratch tests with cochineal dye and carminic acid, the major ingredient of cochineal dye, were also positive...

In order to know more about allergy to food colouring, we conducted a prospective open study over 8 months in a group of 10 atopic children with repeated urticaria. The mean age was 6.5 years (4.2 - 13.5 years). The diagnosis was based on oral challenge tests along with hisory taking there were 3 cases of allergy to food colourings. Clinical features were mainly skin symptoms, sometimes associated with GI manifestations which were not only rare (1 case in our series) but also non specific. Colourings-free diet was recommended in consequence...

Cochineal carmine, or simply carmine (E120), is a red colouring that is obtained from the dried bodies of the female insect Dactylopius coccus Costa (the cochineal insect). We have evaluated the prevalence of sensitization and asthma caused by carmine in a factory using natural colouring, following the diagnosis of two workers with occupational asthma. The accumulated incidence of sensitization and occupational asthma due to carmine in this factory are 48.1% and 18.5% respectively, figures that make the introduction of preventive measures obligatory...

Foods contain a wide range of food ingredients that serve numerous technical functions. Per capita consumer exposure to most of these food ingredients is rather low with a few notable exceptions such as sugar and starch. Some food ingredients including edible oils, hydrolyzed proteins, lecithin, starch, lactose, flavors and gelatin may, at least in some products, be derived from sources commonly involved in IgE-mediated food allergies. These ingredients should be avoided by consumers with allergies to the source material if the ingredient contains detectable protein residues...

BACKGROUND: There have been several reports of carmine allergy; however, identification of the responsible carmine allergens has not been widely documented. METHODS: Three female patients presented with a history of anaphylaxis and/or urticaria/angioedema after ingestion of carmine-containing foods. All three patients had 4+ skin prick tests to carmine. Among them, two patients were confirmed to have carmine allergy by blinded, placebo-controlled food challenges to carmine...

Carmine (E120), a natural red dye extracted from the dried females of the insect Dactylopius coccus var. Costa (cochineal), has been reported to cause hypersensitivity reactions. We report a case of occupational asthma and food allergy due to carmine in a worker not engaged in dye manufacturing. A 35-year-old nonatopic man, who had worked for 4 years in a spice warehouse, reported asthma and rhinoconjunctivitis for 5 months, related to carmine handling in his work. Two weeks before the visit, he reported one similar episode after the ingestion of a red-colored sweet containing carmine...

The prevalence of food allergies (FA) has increased over the past fifteen years. The reasons suggested are changes in dietary behaviour and the evolution of food technologies. New cases of FA have been described with chayote, rambutan, arguta, pumpkin seeds, custard apple, and with mycoproteins from Fusarium.... Additives using food proteins are at high risk: caseinates, lysozyme, cochineal red, papaïn, alpha-amylase, lactase etc. Heating can reduce allergenicity or create neo-allergens, as well as storage, inducing the synthesis of allergenic stress or PR proteins...

We report five cases of anaphylactic reaction to carmine (cochineal, E120) after patients drank an alcoholic beverage. By means of positive skin prick tests (SPT) and positive RAST to carmine. IgE-mediated sensitization could be established. One nonatopic patient showed also a great amount of serum IgE antibodies to the carmine acid-albumin conjugate. Due to its widespread use in the food and cosmetic industry, carmine should be tested in the allergy work-up in case of allergic reactions after a drink or a meal...
