ABSTRACT

Las alteraciones durante la vida prenatal tienen diversos efectos en los organismos. La restricción alimentaria materna ocasiona modificaciones en la conducta alimentaria como hiperfagia y su exacerbación ante la exposición a una dieta hiperlipídica. La evidencia experimental indica que aun cuando existe una preferencia por los alimentos altos en grasa, cuando las ratas realizan actividad física, esta preferencia disminuye o se elimina. Objetivo: evaluar el efecto de la restricción alimentaria materna sobre el consumo de una dieta suplementada con nuez pecana y cómo influye la actividad física. El experimento incluyó 22 ratas, 11 del grupo experimental y 11 del grupo control. De los cuales 6 realizaron actividad y 5 permanecieron sedentarias en cada grupo (machos y hembras). El experimento duró 114 días, de los cuales 42 días tuvieron disponible la rueda de actividad. Los resultados mostraron que la restricción alimentaria materna no modificó el comportamiento alimentario, sin embargo, cuando incrementaron la actividad por la disponibilidad de la rueda de actividad, los sujetos experimentales aumentaron su consumo de nuez pecana. Los resultados se consideran contradictorios con respecto a la literatura, ya que muestran ausencia de hiperfagia e incremento en el consumo a la par del incremento en actividad física.


Alterations during prenatal life have various effects on organisms. Maternal food restriction causes changes in feeding behavior such as hyperphagia and its exacerbation when exposed to a hyperlipidic diet. Experimental evidence indicates that even when there is a preference for high-fat foods, when rats do physical activity, this preference decreases or is eliminated. Objective: to evaluate the effect of maternal dietary restriction on the consumption of a diet supplemented with pecan nuts and how physical activity influences this relationship. The experiment included 22 rats, 11 experimental and 11 controls. Of these, 6 performed physical activity and 5 remained sedentary in each group (males and females). The experiment lasted 114 days; the activity wheel was available on 42 days. The results showed that maternal food restriction did not modify eating behavior, however, when rats increased physical activity, experimental subjects increased their consumption of pecan nuts. The results are contradictory with respect to the literature, as they show an absence of hyperphagia and an increase in consumption along with an increase in physical activity.

ABSTRACT

BACKGROUND: The prevalence of peanut allergy (PA) among children has increased significantly over the past decade. Even though the prevalence of PA in Singapore is considered low, peanut is the top trigger for food-induced anaphylaxis in Singaporean children.OBJECTIVE: To describe the demographic characteristics and clinical features of children with PA.METHODS: This is a 5-year retrospective review of children diagnosed with PA based on clinical history coupled with a positive skin prick test to peanut or positive oral food challenge results.RESULTS: There were 269 patients (53.9% males) with a clinical diagnosis of PA. The median age at first allergic presentation for the PA group was 24 months old, with interquartile range of 13–39 months. The most common form of peanut introduced was roasted peanut. The rate of peanut anaphylaxis was 7.1%. Concomitant tree nut sensitization was found in 32.3% of this cohort, predominantly to cashew nut. Majority of them have a personal history of atopy – 75.8% with eczema, 63.6% with allergic rhinitis, and 19.7% with asthma.CONCLUSION: This is the first large review of peanut-allergic children in Singapore. Prospective population-based studies are needed to establish the true prevalence and risk factors associated with the development of this potentially life-threatening condition.

ABSTRACT

The relationship between areca nut as a primary carcinogen and oral cancer has been widely concerned. Areca can change the levels of reactive oxygen species (ROS) and autophagy in cells, and the levels of ROS and autophagy are closely related to the occurrence and development of tumors. This paper reviewed the relationships among areca nut, intracellular ROS, and autophagy.

ABSTRACT

Cardiovascular diseases (CVD) are the main cause of death globally and most CVD can be prevented by addressing their risk factors, such as an unhealthy diet. Many authors have studied the benefits of nut consumption on CVD. Nuts contain high amounts of vegetable protein, unsaturated fatty acids, dietary fibers, vitamins, minerals and many other bioactive compounds, like phytosterols and phenolic compounds, which are able to reduce cholesterol levels and promote antioxidant and anti-inflammatory effects, thereby reducing cardiovascular risks. This review aims to describe studies involving the consumption of nuts, including Brazil nuts and CVD risk factors with positive results in the improvement of lipid profile, glucose metabolism, vascular function, and inflammatory and oxidative stress biomarkers

ABSTRACT

BACKGROUND: The Pink peppercorn belongs to the same Anacardiaceae family as cashew and pistachio. However, the cross-reactivity of pink peppercorn with cashew and pistachio has yet to be studied. To date, there has been a single case report of anaphylaxis to pink peppercorn in a cashew and pistachio allergic individual. OBJECTIVE: We aim to demonstrate cross-sensitization to pink peppercorn in cashew and/or pistachio allergic children. METHODS: A small descriptive cohort study looking at cross-sensitization of pink peppercorn in cashew and/or pistachio allergic children was conducted. Children with a history of reaction to pistachio and/or cashew nut underwent skin prick tests to the pink peppercorn species Schinus terebinthifolius to determine cross-sensitization. RESULTS: Out of the 21 cashew and/or pistachio allergic subjects, 16 (76.2%) demonstrated cross-sensitization to pink peppercorn. None of the subjects had any knowledge of previous exposure or allergic reactions to pink peppercorn. DISCUSSION: This study demonstrates potential cross-reactivity between pink peppercorn and cashew and pistachio. While an oral food challenge to pink peppercorn would have been important in demonstrating clinical cross-reactivity, this was not performed due to ethical constraints. We hope to increase the awareness of pink peppercorn as a potential and hidden source of allergen and encourage further studies to demonstrate the clinical cross-reactivity and to better delineate the major allergen involved.

ABSTRACT

BACKGROUND: Anaphylaxis is increasing in young children. The aim of the present study was to analyze the clinical characteristics of anaphylaxis in Korean infants, with a focus on food triggers. METHODS: The study analyzed the medical records of infants aged 0 to 2 years old who had been diagnosed with anaphylaxis in 23 secondary or tertiary hospitals in Korea. RESULTS: We identified 363 cases of infantile anaphylaxis (66.9% male). Cutaneous symptoms were most prevalent (98.6%), followed by respiratory (83.2%), gastrointestinal (29.8%), and neurologic (11.6%) symptoms. Cardiovascular symptoms were noted in 7.7% of the cases. Most of the cases of anaphylaxis (338; 93.1%) were induced by foods. The most common trigger food was cow's milk and cow's milk products (43.8%), followed by hen's eggs (21.9%), walnuts (8.3%), wheat (7.7%), peanuts (4.8%), other nuts (3.0%), and fish (2.1%). In cow's milk-induced anaphylaxis cases, more than half the cases had cow's milk specific immunoglobulin E (sIgE) levels that were lower than the diagnostic decision points (DDPs), which is 5 kUA/L for those under the age of 1 and 15 kUA/L for those over the age of 1. In anaphylaxis induced by hen's egg, most of the cases (91.8%) had hen's egg sIgE levels that were higher than the DDP, which is 2 kUA/L for those under the age of 2 and 7 kUA/L for those over the age of 2. Of the infantile anaphylaxis cases, 46.8% had been treated with epinephrine, and 25.1% had been prescribed an epinephrine auto-injector. CONCLUSION: Cow's milk is the most frequent trigger food of anaphylaxis in Korean infants. However, we found no significant correlation between the sIgE level and clinical severity. Education is required regarding the importance of epinephrine as the first line therapy for anaphylaxis and on properly prescribing epinephrine for infants with a history of anaphylaxis.

ABSTRACT

Acute myocardial infraction (AMI) is a highly frequent cause of mortality and disability around the world. The aim of the present study was to evaluate the associations between meat group intake levels and AMI risks in an adult Iranian population. This case-control study was conducted on 200 first AMI cases and 200 healthy individuals matched by age, sex, and body mass index. A Food Frequency Questionnaire validated for Iranian populations was used to assess usual dietary intake levels over the previous year. Data was extracted regarding the meat group—including meat (red and processed), fish, poultry, eggs, nuts, and legumes. The associations between meat group items and AMI were calculated by multivariable logistic regression. Red meat consumption was significantly positively associated with increased risk of AMI. After adjustment for potential confounders, a positive association was found between higher frequency of processed and red meat intake, and increased risk of AMI (processed meat consumption: odds ratio [OR], 1.71; 95% confidence interval [CI], 1.31–2.23 and red meat consumption: OR, 2.51; 95% CI, 1.84–5.11). In addition, the results indicated an inverse association between the frequency of nuts consumption and AMI (OR, 0.52; 95% CI, 0.31–0.92). There were no associations seen between poultry, fish, eggs and beans intake levels, and the odds of AMI. The current study suggested a direct association between the frequency of processed/red meat consumption and increased AMI risks. In addition, an inverse relation was observed between frequency of nuts consumption and the risks of AMI.

ABSTRACT

With increasing need to prevent serious food allergy reactions, Korean food allergen labeling regulation has been revised repeatedly. This paper aims to summarize current statuses of food allergen labeling in Korea and foreign countries and to analyze the issue of food allergen labeling regulation. Korean food labeling regulation currently requires 19 items and 22 foods to be reported on labels (eggs, milk, buckwheat, peanut, soybean, wheat, mackerel, crab, shrimp, pork, peach, tomato, sulfite, walnut, chicken, beef, squid, shellfish, and pine nut). However, some common food triggers (for example, almond, cashew nut, and kiwi fruit) are not included in the current labeling regulation. Another issue is that the Korean labeling regulation has not yet been fully implemented for nonprepacked foods; thus, consumers still have difficulty in correctly identifying allergenic ingredients in food. It should be assessed whether warning statements for cross-contamination are reasonable. To prevent the occurrence of serious reactions from accidental ingestion, efforts must be made to solve recently raised issues including the items required to be listed on food labels, the system of standards for labeling and display methods.

ABSTRACT

PURPOSE: Many studies have reported that pollen-food allergy syndrome (PFAS) can cause anaphylaxis. No comprehensive investigations into anaphylaxis in PFAS have been conducted, however. In this study, we investigated the clinical manifestations and risk factors for anaphylaxis in PFAS in Korean patients with pollinosis. MATERIALS AND METHODS: Data were obtained from a nationwide cross-sectional study that previously reported on PFAS in Korean patients with pollinosis. Data from 273 patients with PFAS were collected, including demographics, list of culprit fruits and vegetables, and clinical manifestations of food allergy. We analyzed 27 anaphylaxis patients and compared them with patients with PFAS with oropharyngeal symptoms only (n=130). RESULTS: The most common cause of anaphylaxis in PFAS was peanut (33.3%), apple (22.2%), walnut (22.2%), pine nut (18.5%), peach (14.8%), and ginseng (14.8%). Anaphylaxis was significantly associated with the strength of sensitization to alder, hazel, willow, poplar, timothy, and ragweed (p<0.05, respectively). Multivariable analysis revealed that the presence of atopic dermatitis [odds ratio (OR), 3.58; 95% confidence interval (CI), 1.25–10.23; p=0.017]; sensitization to hazel (OR, 5.27; 95% CI, 1.79–15.53; p=0.003), timothy (OR, 11.8; 95% CI, 2.70–51.64; p=0.001), or ragweed (OR, 3.18; 95% CI, 1.03–9.87; p=0.045); and the number of culprit foods (OR, 1.25; 95% CI, 1.15–1.37; p<0.001) were related to the development of anaphylaxis in PFAS. CONCLUSION: The most common culprit foods causing anaphylaxis in PFAS were peanut and apple. The presence of atopic dermatitis; sensitization to hazel, timothy, or ragweed; and a greater number of culprit foods were risk factors for anaphylaxis in PFAS.

ABSTRACT

BACKGROUND/OBJECTIVES: Little is known about the dietary patterns (DPs) of women during pregnancy. The present study aimed to identify the DPs of pregnant Malaysian women and their associations with socio-demographic, obstetric, and anthropometric characteristics. SUBJECTS AND METHODS: This prospective cohort study included 737 participants enrolled in Seremban Cohort Study between 2013 and 2015. Food consumption was assessed using a validated 126-food item semi-quantitative food frequency questionnaire (SFFQ) at four time-points, namely, pre-pregnancy and at each trimester (first, second, and third). Principal component analysis (PCA) was used to identify DPs. RESULTS: Three DPs were identified at each time point and designated DP 1–3 (pre-pregnancy), DP 4–6 (first trimester), DP 7–9 (second trimester) and DP 10–12 (third trimester). DP 1, 4, and 7 appeared to be more prudent diets, characterized by higher intakes of nuts, seeds & legumes, green leafy vegetables, other vegetables, eggs, fruits, and milk & dairy products. DP 2, 5, 8, and 11 had greater loadings of condiments & spices, sugar, spreads & creamer, though DP 2 had additional sweet foods, DP 5 and 8 had additional oils & fats, and DP 11 had additional tea & coffee, respectively. DP 3 and 6 were characterized by high protein (poultry, meat, processed, dairy, eggs, and fish), sugars (mainly as beverages and sweet foods), and energy (bread, cereal & cereal products, rice, noodles & pasta) intakes. DP 9 had additional fruits. However, DP 12 had greater loadings of energy foods (bread, cereal & cereal products, rice, noodles & pasta), sugars (mainly as beverages, and sweet foods), and good protein sources (eggs, nuts, seeds & legumes). Malays were more likely to have lower adherence (LA) for DP 1 and 10 than non-Malays. DP 2, 8, and 11 were more prevalent among Malays than non-Malays. Women with a higher education were more likely to have LA for DP 10, and women with a greater waist circumference at first prenatal visit were more likely to show LA for DP 11. CONCLUSIONS: DPs observed in the present study were substantially different from those reported in Western populations. Information concerning associations between ethnicity, waist circumference and education with specific DPs before and throughout pregnancy could facilitate efforts to promote healthy dietary behavior and the overall health and well-being of pregnant women.

ABSTRACT

BACKGROUND: This study aimed to investigate the food intake behavior of cancer survivors based on main sources of energy intake from different food groups in comparison with healthy individuals.METHODS: Baseline survey data from the Health Examinee cohort, which recruited participants from 2014 to 2013 were applied. A total of 5,269 cancer survivors and 5,219 healthy subjects without comorbidities who were matched by age, sex, and enrollment center were included in the analysis. The proportion of energy intake for 17 food groups was devided into lower median and median or upper. OR and 95% CIs were determined to measure the difference of energy intake proportion in cancer survivors, five major types of cancer survivors versus healthy individuals.RESULTS: Generally, the proportion of calories intake from sugars and sweets, meat and poultry, oils and fats, and beverage was lower in cancer survivors than in healthy individuals (OR = 0.83 [95% CI = 0.79–0.88], 0.75 [95% CI = 0.71–0.80], 0.84 [95% CI = 0.80–0.89], and 0.93 [95% CI = 0.88–0.99], respectively) with more prominently shown in breast, colon, and thyroid cancer individuals. In contrast, cancer survivors tended to intake calories from potatoes and starches, legume, seeds and nuts, vegetables, mushrooms, fruits, and seasonings more than healthy individuals (OR = 1.09 [95% CI = 1.03–1.16], 1.13 [95% CI = 1.06–1.19], 1.15 [95% CI = 1.09–1.22], 1.07 [95% CI = 1.01–1.13], 1.07 [95% CI = 1.02–1.14], 1.15 [95% CI = 1.08–1.21], and 1.17 [95% CI = 1.10–1.23], respectively) which were more prominent in gastric and breast cancer survivors.CONCLUSIONS: The dietary behavior measured by main sources of energy intake in cancer survivors was different from healthy individuals in terms of several food groups. Although there are nutrition guidelines for cancer survivors, because of the differences between Western population and Asian people in terms of food culture, the guidelines for balanced nutritious behavior should be established among Asian cancer survivors.

ABSTRACT

Abstract In this study I tested the effect of Syagrus loefgrenii nut size and number on the intensity of removal by rodents across seasons. Trials were performed in which piles of either small or large endocarps (1, 3, 6, 12, and 25) were subjected to removal by rodents in the Cerrado (Brazilian savanna). Despite of variations in the intensity of removal, always this process decrease conform endocarp number. Also, mean proportion of endocarp removal was unrelated to year period, initial number, and size of endocarps. Hence, endocarp removal was consistently negative density-dependent. As, in principle, the observed patterns of nut removal point out similar survival chances for both nut sizes, the pervasive negative density-dependent response emerges as a strategy in S. loefgrenii to swamp rodents all year round irrespective of seed size.


Resumo Avaliei o efeito do tamanho e densidade de endocarpos de Syagrus loefgrenii sobre a intensidade de remoção por roedores conforme a estação do ano. Para tanto, desenvolvi experimentos no Cerrado em que pilhas de endocarpos pequenos ou grandes (1, 3, 6, 12 e 25), foram sujeitos à remoção por roedores. Apesar da intensidade de remoção variar ao longo do ano, sempre esse processo teve relação inversa com o número de endocarpos. Além disso, em qualquer estação do ano, as proporções médias de endocarpos removidos sempre foram menores nas pilhas maiores, independentemente do tamanho dos endocarpos. Portanto, o processo de remoção de endocarpos foi negativamente dependente da densidade. Como, em princípio, os padrões de remoção em S. loefgrenii sugerem chances similares de sobrevivência tanto para endocarpos grandes, quanto pequenos, a preponderância de resposta negativamente dependente da densidade emerge como uma estratégia de S. loefgrenii voltada a saciar roedores em qualquer período do ano independentemente do tamanho de suas sementes.

ABSTRACT

BACKGROUND: There has been an increasing trend of nut allergies in Singapore. OBJECTIVE: The aim of this study was to review the clinical characteristics of children with cashew nut allergy. METHODS: A retrospective analysis was conducted in a tertiary paediatric referral centre in Singapore from 2008 to 2015. A total of 99 subjects with positive specific IgE (≥0.35 IU/L) to cashew nut were identified. Clinical features including demographics, clinical reaction to cashew nut, associations with other nuts and test specific measurements were recorded. RESULTS: The results showed that cutaneous symptoms (71.2%) were the most common allergic manifestations. Anaphylaxis occurred in 3.8% of children. In addition, all cashew nut allergic subjects were cross-reactive (either sensitized or allergic) to pistachio. Cross-reactivity rate with peanuts was 53.8%. There was a strong prevalence of atopy among cashew nut allergic subjects. CONCLUSION: In conclusion, cashew nut allergy is a significant tree nut allergy in Singapore.

ABSTRACT

BACKGROUND: In developing countries, there is a lack of epidemiological information related to food hypersensitivity, including nuts and seafood. OBJECTIVE: The aim was to determine the prevalence of allergic reactions and clinical manifestations associated with the consumption of nuts and seeds or seafood in university students. METHODS: We designed an observational cross-sectional study. A structured questionnaire was applied to Mexican university students to identify allergic reactions associated with the consumption of nuts and seeds, and seafood. RESULTS: A sample of 1,200 students was included; mean age of 19.7 ± 1.7 years. Prevalence of symptoms associated with the consumption of nuts and seeds, and seafood were 2.8% (33 of 1,200) and 3.5% (42 of 1,200) respectively. The main clinical manifestations were abdominal pain (63.6% in nuts and seeds), flushing (50% in seafood), and pharyngeal oppression (19% in seafood). Prevalence of perceived, probable and systemic allergy to nuts and seeds was 2.8% (95% confidence interval [CI], 2.5%–3.0%), 0.8% (95% CI, 0.3%–1.3%) and 0.2% (95% CI, 0%–0.4%) respectively. On the other hand, the prevalence (perceived, probable, and systemic) associated with seafood consumption was 3.5% (95% CI, 2.5%–4.5%), 1.8% (95% CI, 1.0%–2.5%), and 0.5% (95% CI, 0.1%–0.9%). Walnut and shrimp were the most frequently reported foods. CONCLUSION: For every 100 Mexican university students, approximately 3 or 4 perceived to have allergy attributed to the consumption of some nuts and seeds or seafood, while 1 or 2 students would have a probable reaction to this same type of food. Walnut and shrimp would be causing the higher quantity of food allergic reactions.

ABSTRACT

OBJECTIVES: Areca nut is widely consumed in many parts of the world, especially in South and Southeast Asia, where cardiovascular disease (CVD) is also a huge burden. Among the forms of CVD, acute coronary syndrome (ACS) is a major cause of mortality and morbidity. Research has shown areca nut chewing to be associated with diabetes, hypertension, oropharyngeal and esophageal cancers, and CVD, but little is known about mortality and re-hospitalization secondary to ACS among areca nut users and non-users. METHODS: A prospective cohort was studied to quantify the effect of areca nut chewing on patients with newly diagnosed ACS by categorizing the study population into exposed and non-exposed groups according to baseline chewing status. Cox proportional hazards models were used to examine the associations of areca nut chewing with the risk of re-hospitalization and 30-day mortality secondary to ACS. RESULTS: Of the 384 ACS patients, 49.5% (n=190) were areca users. During 1-month of follow-up, 20.3% (n=78) deaths and 25.1% (n=96) re-hospitalizations occurred. A higher risk of re-hospitalization was found (adjusted hazard ratio [aHR], 2.05; 95% confidence interval [CI], 1.29 to 3.27; p=0.002) in areca users than in non-users. Moreover, patients with severe disease were at a significantly higher risk of 30-day mortality (aHR, 2.77; 95% CI, 1.67 to 4.59; p < 0.001) and re-hospitalization (aHR, 2.72; 95% CI, 1.73 to 4.26; p < 0.001). CONCLUSIONS: The 30-day re-hospitalization rate among ACS patients was found to be significantly higher in areca users and individuals with severe disease. These findings suggest that screening for a history of areca nut chewing may help to identify patients at a high risk for re-hospitalization due to secondary events.

ABSTRACT

Oral allergy syndrome (OAS) is an IgE-mediated allergy caused by cross-reacting antigenic determinants in pollens and various fruits, vegetables, and nuts which are known as the most common food allergy in adults. Cross-reactive antigenic proteins include pathogenesis-related-10 protein, profilin, cross-reactive carbohydrate determinant and lipid transfer protein. The prevalence of OAS has been reported at up to 70% of birch pollen allergy. A nationwide multicenter study in our country has recently reported that the prevalence of OAS in Korea is 41.7% of pollen allergy. Typical symptoms of OAS are tingling, itching sense and edema of lips, mouth, and throat immediately after ingestion of raw fruits, vegetables, or nuts. These can progress to systemic symptoms including anaphylaxis. The diagnosis can be made by typical clinical history in patients with pollen allergy. Skin prick test using fresh fruits extracts can be helpful in confirming sensitization to foods, which has better sensitivity than commercial skin prick test or serum specific IgE test. Treatment of OAS is to avoid causative foods. Self-injectable epinephrine should be considered in the case of anaphylaxis. Allergen-specific immunotherapy to pollens has also been tried.

ABSTRACT

Cytologic diagnosis of nuclear protein in testis (NUT) midline carcinoma (NMC) is important due to its aggressive behavior and miserable prognosis. Early diagnosis of NMC can facilitate proper management, and here we report two rare cases of thoracic NMC with cytohistologic correlation. In aspiration cytology, the tumor presented with mixed cohesive clusters and dispersed single cells, diffuse background necrosis and many neutrophils. Most of the tumor cells had scanty cytoplasm and medium-sized irregular nuclei, which had fine to granular nuclear chromatin. Interestingly, a few dyskeratotic cells or squamoid cell clusters were present in each case. Biopsy specimen histology revealed more frequent squamous differentiation, and additional immunohistochemistry tests showed nuclear expression of NUT. Because this tumor has a notorious progression and has been previously underestimated in terms of its prevalence, awareness of characteristic findings and proper ancillary tests should be considered in all suspicious cases.

ABSTRACT

PURPOSE: Foreign body aspiration in children is emergent and can cause serious complications. This study aims to show the clinical characteristics of foreign body aspiration and to analyze the clinical cases of delayed diagnosis to predict and prevent complications. METHODS: We retrospectively reviewed the medical records of 63 children (48 in Inha University Hospital and 15 in Gachon University Gil Medical Center) who were diagnosed with foreign body aspiration through bronchoscopy from 1996 to 2017 in Incheon City, and analyzed clinical characteristics. Patients were divided into 3 groups: those were diagnosed within 24 hours, delayed after 24 hours, or delayed more than 7 days according to time elapse from the time of foreign body aspiration, and clinical characteristics of each group were compared. RESULTS: Aspiration occurred in 58.7% at 1 year and 15.9% at 2 years. Cough (65.1%) and coarse breathing sound (41.3%) were most common, and radiologic findings were commonly presented as emphysema on the affected side (41.3%). Nuts were most common (42.9%), and there was no difference in the frequency between the right and left main bronchi. The documented history of foreign body aspiration was more frequently found in the early diagnosed group; however, sputum, fever, and complications were more frequent in the delayed diagnosed group. CONCLUSION: If a patient with respiratory disease has persistent fever or sputum, foreign body aspiration should be suspected.

ABSTRACT

BACKGROUND: Oral allergy syndrome (OAS) is a type of allergic reaction that mainly occurs on oral contact with raw fruit, vegetables, or nuts. The most common type of OAS is birch pollen-related food allergy. Although OAS is a common food allergy in adults, only few epidemiologic studies have been reported in Korea. Here we investigate the prevalence and triggers of birch pollen-related food allergy. METHODS: We conducted a retrospective chart review of 1,427 patients who underwent a skin prick test for inhalant allergens at the Asthma and Allergy Clinic in Seoul National University Bundang Hospital from January 2011 to December 2016. RESULTS: Of 1,427 patients, 125 (8.7%) were sensitized to birch pollen. Among them, 20.0% developed OAS, which was the most common food allergy (96.2%). The prevalence of OAS was higher in females, and was 18.2% in birch pollen-sensitized allergic rhinoconjunctivitis patients. Further, 72.0% OAS patients had rhinoconjunctivitis, 20.0% had asthma, and 12.0% had chronic urticaria. Apple (68.0%), peach (56.0%), nuts (36.0%), kiwi (20.0%), persimmon (20.0%), plum (16.0%), and cherry (16.0%) were frequent triggers; however, Chinese yam, kudzu vine, bellflower root, codonopsis, and ginseng were also revealed as triggers. Patients (60.0%) showed OAS with ≥ 3 foods at the same time. Only 3 patients showed mono-sensitivity to birch pollen, while others were multi-sensitized to trees, grasses, weed, or house dust mite allergens. CONCLUSION: OAS was the most common food allergy in birch pollen-sensitized patients. This study revealed the unique triggers of OAS in Korea in addition to well-known triggers.
