Skin prick tests and in vitro immunoassays with native spices and spice extracts.

BACKGROUND: Skin prick tests of native spices (commercial powdered spices) are common in patients with allergy to birch or mugwort pollen. Clinical symptoms from spices are infrequent but occasionally severe. OBJECTIVE: To compare the skin prick test results with native spices and spice extracts and to determine the clinical relevance of test material. METHODS: Skin prick tests with the native spices coriander, caraway, paprika, cayenne, mustard, and white pepper were made twice at 2-month to 2.9-year intervals in 49 patients. During the latter time, tests were also made with spice extracts and spice-specific serum IgE was measured. RESULTS: The reproducibility of skin test results with native spices was 67% to 100%. Spice extracts, except white pepper, elicited positive skin test reactions in half those with positive reactions to native spices. Higher specific IgE concentrations (> or = 3.5 PRU/mL) were seen in cases where the skin tests were positive to the corresponding spices with 5% extracts of > 8 kD Mw. Three-fourths of the patients with positive skin tests to native spices were positive to birch pollen and one-half to a vegetable. Mild clinical symptoms from spices were reported by one-third. CONCLUSIONS: Spice allergens partly crossreact with those of pollens and vegetables. A minority of spice allergens may give clinical symptoms. The > 8-kD 5% extracts may be relevant skin prick test materials for identifying patients at risk of developing severe symptoms from ingested spices.

Spice allergy: results of skin prick tests and RAST with spice extracts.

Skin prick tests (SPT) with freeze-dried spices and 5% (w/v) spice extracts were performed on 50 patients with 2+ or stronger SPT reactions to spices per se, and RAST were performed on 10 of them. Freeze-dried extracts produced mostly equal or stronger SPT reactions than corresponding whole spices, but 5% (w/v) extracts produced weaker reactions and also remained totally negative in some patients. Positive RAST results were seen in all 10 patients tested. The correlation between the RAST and SPT results was good for mustard and paprika, but poor for cayenne, coriander, caraway and white pepper. Five patients with positive SPT and RAST for spices contracted rhinitis from powdered spices in their working environments, and one patient suffered from gastrointestinal pains caused by spiced food. The others had noticed no clinical symptoms caused by spices. The present results thus indicate that both SPT and RAST should include purified spice extracts.

Influence of spices and spice principles on hepatic mixed function oxygenase system in rats.

The status of hepatic mixed function oxygenase system (MFOS) was investigated in rats fed spice principles: capsaicin, piperine and curcumin, as well as spices: cumin, ginger, fenugreek, cinnamon, asafoetida, mustard and tamarind at two dietary levels each. Liver microsomal cytochrome P450-dependent aryl hydroxylase was generally stimulated by these spice principles and spices. Cumin, ginger and fenugreek also stimulated the levels of cytochrome P450 and cytochrome b5 and cumin and tamarind stimulated N-demethylase activity. NADPH-cytochrome c reductase and glucuronyl transferase activities, however, remained unaffected by the spices tested.

Characterization of allergens in plant-derived spices: Apiaceae spices, pepper (Piperaceae), and paprika (bell peppers, Solanaceae).

Allergens in spices from the botanic families Apiaceae, Piperaceae, and Solanaceae were characterized. IgE-immunoblotting and IgE-inhibition experiments revealed broad cross-reactivity among spices and to pollen-derived proteins. Moreover, monoclonal antibodies raised against cross-reactive pollen allergens (profilin, Bet v 1) detected homologous proteins in almost every spice source analyzed. It can be concluded that allergy to spices rarely represents an autonomous sensitization, but is rather a consequence of pollen allergy on the basis of immunologic cross-reactivity.

[So-called "celery-carrot-mugwort-spice syndrome." RAST results with new spice discs].

RAST investigations on the sera of 27 patients suffering from celery allergy showed specific IgE to mugwort and birch in 15 cases; sensitization to mugwort or birch alone only occurred in 5 and 7 cases, respectively. Positive RAST results were also obtained with several spices. We found a relationship between spice and celery allergy.

Antimicrobial functions of spices: why some like it hot.

Although spices have been important for centuries in food preparation throughout the world, patterns of spice use differ considerably among cultures and countries. What factors underlie these differences? Why are spices used at all? To investigate these questions, we quantified the frequency of use of 43 spices in the meat-based cuisines of the 36 countries for which we could locate traditional cookbooks. A total of 4578 recipes from 93 cookbooks was analysed. We also complied information on the temperature and precipitation in each country, the ranges of spice plants, and the antibacterial properties of each spice. These data were used to investigate the hypothesis that spices inhibit or kill food-spoilage microorganisms. In support of this is the fact that spice plant secondary compounds are powerful antimicrobial (i.e., antibacterial and antifungal) agents. As mean annual temperatures (an indicator of relative spoilage rates of unrefrigerated foods) increased, the proportion of recipes containing spices, number of spices per recipe, total number of spices used, and use of the most potent antibacterial spices all increased, both within and among countries. Likewise, the estimated fraction of bacterial species inhibited per recipe in each country was positively correlated with annual temperature. Several alternative hypotheses were considered--that spices provide macronutrients, disguise the taste and smell of spoiled foods, or increase perspiration and thus evaporative cooling; it also is conceivable that spice use provides no benefits. However, none of these four alternatives was well supported by our data. The proximate reason spices are used obviously is to enhance food palatability. But the ultimate reason is most likely that spices help cleanse foods of pathogens and thereby contribute to the health, longevity and reproductive success of people who find their flavors enjoyable.

Characterization of allergens in Apiaceae spices: anise, fennel, coriander and cumin.

BACKGROUND: Symptoms elicited by IgE-mediated food allergy range from mild local to severe systemic reactions. Allergens in spices are particularly dangerous due to their hidden presence in many dishes. OBJECTIVES AND METHODS: According to clinical observations, mugwort and birch pollen allergy, and hypersensitivity to spices are frequently associated, but the crossreacting compounds were not defined so far. We tested sera of 15 patients who experienced adverse reactions to spiced food and characterized their IgE-binding patterns on anise, fennel, coriander and cumin extracts through immunoblot and inhibition experiments. RESULTS: The use of anti-Bet v 1 (MoAb) and anti-profilin (rabbit) antibodies revealed the presence of crossreacting allergens in the tested spice extracts. Inhibition experiments showed that IgE-binding to allergens in Apiaceae spices could be blocked by preincubation of sera with rBet v 1 or rBet v 2 (birch profilin). Moreover, we detected crossreacting allergenic molecules in the molecular weight range of 60 kDa. IgE-binding to spice allergens occurred only with sera of 10/15 (66%) patients with allergy to pollen (birch, mugwort) and/or celeriac. In five out of 15 (33%) patients with a history of adverse reaction to spices, but without pollen and celeriac allergy, no IgE-binding to any spice protein could be demonstrated. It is possible that these clinical reactions could be elicited by other types of hypersensitivity (Type II, III, IV), however, as spices contain highly reactive substances, the symptoms may most likely be classified as food-intolerant. CONCLUSIONS: Bet v 1- and profilin-related allergens may, besides higher molecular weight allergenic molecules, be responsible for Type I allergy to anise, fennel, coriander or cumin, members of the Apiaceae.

Insulin potentiating factor and chromium content of selected foods and spices.

An unidentified factor that potentiates the action of insulin in glucose metabolism was investigated in selected foods and spices. Chromium content of these foods and spices was also determined. Foods and spices were extracted with 0.1N NH4OH (1:20, w/v) and the supernatants assayed for insulin potentiation activity in the rat epididymal fat cell assay. Among the selected foods, tuna fish, peanut butter, and vanilla ice cream had some insulin potentiating activity. Among the spices, apple pie spice, cinnamon, cloves, bay leaves, and turmeric potentiated insulin activity more than three-fold. Chromium concentration of foods ranged from 1 to 145 ng/g, and spices ranged from 4 to 1818 ng/g. Insulin potentiating activity of foods and spices did not correlate with total chromium. Spices are generally used for flavor and taste in food preparations, but cinnamon, cloves, bay leaves, and turmeric may have an additional role in glucose metabolism.

Common Indian spices: nutrient composition, consumption and contribution to dietary value.

Nutrient composition of eight commonly consumed spices of South India was analysed. Spices analysed were red chillies (Capsicum annum), black pepper (Piper nigrum), coriander seeds (Coriandrum sativum), cumin seeds (Cuminum cyminum), garlic (Allium sativum), asafoetida (Ferula foetida), dry ginger (Zingiber officinale) and ajowan (Carum copticum). The nutrients analysed were proximate principles, minerals, starch, sugars, dietary fibre components, tannins, phytic acid, enzyme inhibitors and amino acids. Dry ginger, ajowan and asafoetida had high calcium (1.0-1.5%) and iron (54-62 mg/100 g) levels. The tannin content of spices was also high (0.9-1.3% DM). Dietary fibre ranged from 14-53%. Spices had appreciable amounts of essential amino acids like lysine and threonine. A survey revealed the average per capita consumption of spices to be 9.54 g and at that level, the nutrient contribution from spices ranged from 1.2 to 7.9% of an average adult Indian male's requirement for different nutrients.

Effect of irradiation on the microbiological status and flavouring materials of selected spices.

Spices from Egyptian local markets were irradiated with different recommended doses (0, 5, 10, 20 and 30 kGy). The spices tested included dried leaves of marjoram (Majorana hortensis Moench), rhizomes of ginger (Zingiber officinale Roscoe) and powdered hot pepper (Capsicum annum L.). The study included the isolation and identification of micro-organisms in spices following their irradiation, as well as gas chromatographic (GLC) chemical analysis for the presence and structure of volatile oils, pungent and pigment materials. The results showed that hot pepper was contaminated more (9.2 x 10(5)/g) than marjoram (4.2 x 10(3)/g) and ginger (14.3 x 10(3)/g) with respect to total aerobic bacterial content. The total contents of moulds were 4.8 x 10(3)/g, 5.7 x 10(3)/g and 19 x 10(3)/g in the same spices, respectively, but the pathogenic moulds and bacterial strains differed according to the type of spice. Irradiation at 10, 20 and 30 kGy caused complete elimination of micro-organisms, whereas 5 kGy was less effective. With the GLC method chosen 18 and 50 compounds could be detected in the extracts of marjoram and ginger, respectively; gamma-terpinen and zingiberen being the major compounds in marjoram and ginger, respectively. A noticeable reduction was observed in the amount of terpenes present in irradiated marjoram; they were converted to monoterpenesalcohols. Ginger was more sensitive to irradiation, especially at high doses, but moderate changes were detected at low doses (5 and 10 kGy). A slight, but significant effect on the capsaicin (pungent compound) in hot-pepper was observed following irradiation, whereas no changes in total pigments resulted at any dose. These results prove that 10 kGy is a sufficiently high dose to eliminate the micro-organisms in spices, causing only slight changes in the flavouring materials.

Occupational allergic contact dermatitis from spices.

About 1000 patients were investigated at our clinic during 1991-1995 for occupational skin disease, and 5 had occupational allergic contact dermatitis from spices. The patients were chefs, or kitchen, coffee room, and restaurant workers. All patients had hand (or finger) dermatitis. The causative spices were: garlic, cinnamon, ginger, allspice and clove. The same patients also had allergic patch test reactions to foods: tomato, lettuce and carrot. Paprika elicited a weak allergic patch test reaction in 2 patients. Occupational allergic contact dermatitis from spices is relatively rare, but needs to be taken into consideration in patients who have hand dermatitis, and work with spices and foods. Patch testing with spices as is is useful, but testing with dilutions in pet, may be needed to confirm that the patch test reactions are allergic. Patients also need to be prick tested with spices and foods.

Immunological and respiratory findings in spice-factory workers.

Immunological and respiratory findings were studied in a group of 45 female spice-factory workers (mean age: 39 years; mean exposure: 17 years). In addition a group of 45 female control workers matched by sex, age, and smoking habit were also studied. Intradermal skin testing with mixed spice dust allergen demonstrated positive skin reactions in 73.3% of exposed and in 33.3% of control workers (P less than 0.001). Increased IgE serum levels were found in 36.8% of exposed and in 9.7% of the control workers (P less than 0.01). The prevalence of chronic respiratory symptoms was significantly higher in the exposed workers than in the control workers (P less than 0.01). There was, however, no consistent correlation between skin reactivity and chronic respiratory symptoms. There was a high prevalence of acute symptoms during the work shift. These complaints were more frequent in workers with positive skin tests for the symptoms of cough, chest tightness, and irritated and dry throat. Ventilatory capacity was measured by recording maximum expiratory flow-volume (MEFV) curves. There were statistically significant mean reductions during the work shift for all measured lung function parameters in workers with positive skin reactions. In those workers with negative skin reactions only FEF50 and FEF25 reached statistical significance. Aqueous extracts of different spices (chilli pepper, paprika, caraway, coriander leaves, coriander seeds, cinnamon, ginger, onion, curry, and parsley) caused a dose-related contractile response of isolated guinea pig tracheal smooth muscle. These data suggest that immunologic reactions to spices are frequent in spice workers and may be related to acute symptoms and lung function changes, but not to chronic changes. The data further suggest that, in addition to any immunologic response these spices may produce in vivo, they probably also provoke direct irritant reactions in the airways as suggested by in vitro data.

Delayed-type allergy to spices.

9 common spices were tested epicutaneously in 338 dermatological patients, 118 of whom were allergic to balsam of Peru. Positive reactions to one or more spices were seen in 50 patients all of whom except 2 were allergic to balsam of Peru. The spices giving positive reactions most often were clove, Jamaica pepper and cinnamon (cassia). 2/3 of the patients allergic to balsam of Peru or spices were women, usually suffering from hand eczema. Peroral challenge with spices was carried out in 71 patients allergic to balsam of Peru. Pompholyx on the palms and other objective symptoms were encountered in 7 cases, 3 of whom showed no reactions to spices in epicutaneous tests.
