Query: Using Diet to Treat Asthma and Eczema
Thirty-five patients who had suffered from bronchial asthma for an average of 12 yr, all receiving long-term medication, 20 including cortisone, were subject to therapy with vegan food for 1 yr. In almost all cases, medication was withdrawn or drastically reduced. There was a significant decrease in asthma symptoms. Twenty-four patients (69%) fulfilled the treatment. Of these, 71% reported improvement at 4 months and 92% at 1 yr. There was a significant improvement in a number of clinical variables; for example, vital capacity, forced expiratory volume at one sec and physical working capacity, as well as a significant change in various biochemical indices as haptoglobin, IgM, IgE, cholesterol, and triglycerides in blood. Selected patients, with a fear of side-effects of medication, who are interested in alternative health care, might get well and replace conventional medication with this regimen.
Current treatment modalities for epidermal growth factor (EGFR)-positive cancers have recently included the use of antibodies and small-molecule tyrosine-kinase inhibitors (TKI). A significant limiting step in the use of these agents is dermatological toxicity, frequently in the form of an acneiform eruption. Present management modalities for this toxicity are largely ineffective. Colloidal oatmeal lotion demonstrates multiple anti-inflammatory properties with known effects on arachidonic acid, cytosolic phospholipase A2 and tumour necrosis factor-alpha pathways, along with an excellent side-effect profile. Treatment with colloidal oatmeal was applied to 11 patients with a rash induced by cetuximab, erlotinib, panitumumab and sorafenib. Of the 10 assessable patients, 6 had complete response and 4 partial response, giving a response rate of 100% with no associated toxicities. Treatment with colloidal oatmeal lotion is efficient in controlling the rash associated with EGFR and multiple TKI, and allows continuation of the antineoplastic treatment.
BACKGROUND: Increased prevalence of allergic diseases in western societies has been described as an epidemic. The precise turning point for the epidemic and the antigens responsible for it remain obscure. OBJECTIVE: To evaluate how the prevalence of atopic disease has changed in terms of detectable sensitization to aeroallergens and dietary allergens in a cross-sectional comparison of subjects from birth cohorts more than 60 years apart. METHODS: We studied four groups of 100 subjects each (at ages 7, 27, 47 and 67 years), representing those born in 1990, 1963-66, 1943-46 and in 1923-26, respectively. Serum total and specific IgE concentrations against aeroallergens and dietary allergens were determined. A questionnaire elicited information on symptoms, allergic diseases and medication. RESULTS: The proportion of subjects with detectable IgE antibodies against aeroallergens increased consistently from the oldest to the youngest birth cohorts; chi2 trend=56.809, P<0.0001. Similar progression was not seen in sensitization to dietary allergens. The proportion of those with diagnosed asthma differed significantly (chi2=13.45, P=0.004) across the birth cohorts. The lowest prevalence of asthma and sensitization to dietary allergens was detected in those born in 1943-46, i.e. during or immediately after World War II. CONCLUSION: Prevalence of sensitization to airborne allergens, unlike that to dietary allergens, has increased over a long period of time. Our results support the concept of the immune function being programmed by external factors early in life. They also call for caution when interpretations of the pace and possible causes of the allergy epidemic are made on the basis of short-term studies.
INTRODUCTION: Although epidemiological evidence seems to support a role for lifestyle factors in the pathogenesis of erectile dysfunction (ED), limited data are available suggesting that dietary changes may improve ED. AIM: To provide an update on clinical evidence regarding the role of dietary factors in ED. METHODS: A systematic literature search was performed using MEDLINE and other database (EMBASE, SCOPUS) with MeSH terms and keywords for "erectile dysfunction", "diet", "dietary patterns", "Mediterranean diet", and "lifestyle". MAIN OUTCOME MEASURES: To examine the data relating to erectile dysfunction with dietary factors, its relationship and the impact of dietary treatment. RESULTS: Only few studies assessed the role or the effect of diet on ED. A dietary pattern which is high in fruit, vegetables, nuts, whole grains, and fish but low in red and processed meat and refined grains is more represented in subjects without ED. Mediterranean diet has been proposed as a healthy dietary pattern based on evidence that greater adherence to this diet is associated with lower all-cause and disease-specific survival. In type 2 diabetic men, those with the highest adherence to the Mediterranean diet had the lowest prevalence of ED and were more likely to be sexually active. In clinical trials, Mediterranean diet was more effective than a control diet in ameliorating ED or restoring absent ED in people with obesity or metabolic syndrome. CONCLUSION: The adoption of a Mediterranean diet may be associated with an improvement of erectile dysfunction.
BACKGROUND: The National Electronic Injury Surveillance System (NEISS) captures a nationally representative probability sample from hospital emergency departments (EDs) in the United States. OBJECTIVE: Emergency department data from NEISS were analyzed to assess the magnitude and severity of adverse events attributable to food allergies. METHODS: Emergency department events describing food-related allergic symptomatology were identified from 34 participating EDs from August 1 to September 30, 2003. RESULTS: Extrapolation of NEISS event data predicts a total of 20,821 hospital ED visits, 2333 visits for anaphylaxis, and 520 hospitalizations caused by food allergy in the United States during the 2-month study period. The median age was 26 years; 24% of visits involved children < or =5 years old. Shellfish was the most frequently implicated food in persons > or =6 years old, whereas children < or =5 years old experienced more events from eggs, fruit, peanuts, and tree nuts. There were no reported deaths. Review of medical records found that only 19% of patients received epinephrine, and, using criteria established by a 2005 anaphylaxis symposium, 57% of likely anaphylactic events did not have an ED diagnosis of anaphylaxis. CONCLUSION: Analysis of NEISS data may be a useful tool for assessing the magnitude and severity of food-allergic events. A criteria-based review of medical records suggests underdiagnosis of anaphylactic events in EDs.
Daily diet may have implications for skin ageing. However, data on the relationship between diet and the parameters of skin conditions are scarce. The present study aimed to examine the associations of biophysical properties of the skin of women with intakes of fats and antioxidant micronutrients as well as food groups as sources of these nutrients. In a cross-sectional study, we measured the hydration, surface lipids and elasticity of the skin of 716 Japanese women using non-invasive techniques. The extent of facial wrinkles in the crow's-foot area was determined by observation using the Daniell scale. Each subject's usual diet was determined with the use of a validated FFQ. After controlling for covariates including age, smoking status, BMI and lifetime sun exposure, the results showed that higher intakes of total fat, saturated fat and monounsaturated fat were significantly associated with increased skin elasticity. A higher intake of green and yellow vegetables was significantly associated with a decreased Daniell wrinkling score. Intake of saturated fat was significantly inversely associated with the Daniell wrinkling score after additional adjustment for green and yellow vegetable intake. Further studies with more accurate measurement methods are needed to investigate the role of daily diet in skin ageing.
OBJECTIVE: To demonstrate the effects of a very low-fat, vegan diet on patients with rheumatoid arthritis (RA). DESIGN: Single-blind dietary intervention study. SUBJECTS AND STUDY INTERVENTIONS: This study evaluated the influence of a 4-week, very low-fat (approximately 10%), vegan diet on 24 free-living subjects with RA, average age, 56 +/- 11 years old. OUTCOME MEASUREMENTS: Prestudy and poststudy assessment of RA symptomatology was performed by a rheumatologist blind to the study design. Biochemical measures and 4-day diet data were also collected. Subjects met weekly for diet instruction, compliance monitoring, and progress assessments. RESULTS: There were significant (p < 0.001) decreases in fat (69%), protein (24%), and energy (22%), and a significant increase in carbohydrate (55%) intake. All measures of RA symptomatology decreased significantly (p < 0.05), except for duration of morning stiffness (p > 0.05). Weight also decreased significantly (p < 0.001). At 4 weeks, C-reactive protein decreased 16% (ns, p > 0.05), RA factor decreased 10% (ns, p > 0.05), while erythrocyte sedimentation rate was unchanged (p > 0.05). CONCLUSION: This study showed that patients with moderate-to-severe RA, who switch to a very low-fat, vegan diet can experience significant reductions in RA symptoms.
Observations of increasing allergy prevalence with decreasing distance from the Equator and positive associations with ambient ultraviolet radiation have contributed to a growing interest in the possible role of vitamin D in the etiology of allergy. The aims of this study were to describe any latitudinal variation in the prevalence of childhood allergy in Australia and to evaluate, in parallel, the individual associations between ultraviolet radiation (UVR)- and vitamin D-related measures and hayfever asthma and both conditions. Participants were population-based controls who took part in a multicenter case-control study, aged 18-61 yr and resident in one of four study regions ranging in latitude from 27°S to 43°S. Data were derived from a self-administered questionnaire, interview and examination by a research officer and biologic sampling. Latitude and longitude coordinates were geocoded from participants' residential locations and climatic data were linked to postcodes of current residence. Stored serum was analyzed for 25-hydroxyvitamin D concentrations and silicone rubber casts of the skin were used as an objective measure of cumulative actinic damage. There was an inverse latitude gradient for asthma (a 9% decrease per increasing degree of latitude); however, this pattern did not persist after adjusting for average daily temperature. There was no association between any of the UVR- or vitamin D-related measures and childhood asthma, but greater time in the sun in winter between the ages 6-15 yr was associated with an increase in the odds of having hayfever [adjusted odds ratios (OR) 1.29; 95% CI 1.01-1.63]. Oral supplementation with cod liver oil in childhood increased the odds of a history of having both asthma and hayfever (2.87; 1.00-8.32). Further investigation of the possible role of early vitamin D supplementation in the development of allergy is warranted. Our results also suggest that solar exposure during childhood may be important in allergic sensitization. Plausible explanations, including biologic mechanisms, exist for both observations. © 2010 John Wiley & Sons A/S.
Artificial food colors (AFCs) have not been established as the main cause of attention-deficit hyperactivity disorder (ADHD), but accumulated evidence suggests that a subgroup shows significant symptom improvement when consuming an AFC-free diet and reacts with ADHD-type symptoms on challenge with AFCs. Of children with suspected sensitivities, 65% to 89% reacted when challenged with at least 100 mg of AFC. Oligoantigenic diet studies suggested that some children in addition to being sensitive to AFCs are also sensitive to common nonsalicylate foods (milk, chocolate, soy, eggs, wheat, corn, legumes) as well as salicylate-containing grapes, tomatoes, and orange. Some studies found "cosensitivity" to be more the rule than the exception. Recently, 2 large studies demonstrated behavioral sensitivity to AFCs and benzoate in children both with and without ADHD. A trial elimination diet is appropriate for children who have not responded satisfactorily to conventional treatment or whose parents wish to pursue a dietary investigation.
The aim of this study was to evaluate the antiinflammatory effect of oatmeal extract oligomer on skin fragments stimulated by a neuromediator, vasoactive intestinal peptide (VIP). Skin fragments (from plastic surgery) were maintained in survival conditions for 6 h. To induce inflammation, VIP was placed in contact with dermis by culture medium. Histological analysis was then performed on hematoxylin- and eosin-stained slides. Edema was evaluated with semiquantitative scores. Vasodilation was studied by quantifying the percentage of dilated vessels according to scores and by measuring their surface by morphometrical image analysis. TNF-alpha dosage was made on culture supernatants. Vasodilation was significantly increased after application of VIP. After treatment with oatmeal extract oligomer, the mean surface of dilated vessels and edema were significantly decreased compared with VIP-treated skin. Moreover, treatment with this extract decreased TNF-alpha.
Urticaria, defined by the presence of wheals and/or angio-edema, is a common condition in children, prompting parents to consult physicians. For its successful management, paediatric-specific features must be taken into account, regarding the identification of eliciting triggers and pharmacological therapy. This review systematically discusses the current best-available evidence on spontaneous acute and chronic urticaria as well as physical and other urticaria types in children. Potential underlying causes, namely infections, food and drug hypersensitivity, autoreactivity and autoimmune or other conditions, and eliciting stimuli are considered, with practical recommendations for specific diagnostic approaches. Second-generation antihistamines are the mainstay of pharmacological treatment aimed at relief of symptoms, which require dose adjustment for pae-diatric use. Other therapeutic interventions are also discussed. In addition, unmet needs are highlighted, aiming to promote research into the paediatric population, ultimately aiming at the effective management of childhood urticaria.
Background The risk of indoor exposure to volatile organic compounds (VOCs) on allergic airway diseases in children remains unknown. Objective We examined the residential concentrations of VOCs, emitted from building materials, paints, furniture, and other lifestyle practices and the risks of multiple allergic diseases as well as the IgE-sensitization in pre-school age children in Sweden. Methods In a case-control investigation (198 case children with asthma and allergy and 202 healthy controls), air samples were collected in the room where the child slept. The air samples were analyzed for the levels of eight classes of VOCs. Results A natural-log unit of summed propylene glycol and glycol ethers (PGEs) in bedroom air (equal to interquartile range, or 3.43 – 15.65 µg/m3) was associated with 1.5-fold greater likelihood of being a case (95% CI, 1.1 – 2.1), 1.5-fold greater likelihood of asthma (95% CI, 1.0 – 2.3), 2.8-fold greater likelihood of rhinitis (95% CI, 1.6 – 4.7), and 1.6-fold greater likelihood of eczema (95% CI, 1.1 – 2.3), accounting for gender, secondhand smoke, allergies in both parents, wet cleaning with chemical agents, construction period of the building, limonene, cat and dog allergens, butyl benzyl phthalate (BBzP), and di(2-ethylhexyl)phthalate (DEHP). When the analysis was restricted to the cases, the same unit concentration was associated with 1.8-fold greater likelihood of IgE-sensitization (95% CI, 1.1 – 2.8) compared to the non-IgE sensitized cases. No similar associations were found for the other classes of VOCs. Conclusion We propose a novel hypothesis that PGEs in indoor air exacerbate and/or induce the multiple allergic symptoms, asthma, rhinitis and eczema, as well as IgE sensitization respectively.
Paediatric asthma is a major clinical concern worldwide and represents a huge burden on family and society. It accounts for a large number of lost school days and may deprive the child of both academic achievement and social interaction. Childhood asthma also places strain on healthcare resources as a result of doctor and hospital visits and the cost of treatment. The prevalence of asthma varies worldwide, possibly because of different exposure to respiratory infection, indoor and outdoor pollution, and diet. Certain risk factors appear to predispose children to developing asthma and atopic disease, including incidence and severity of wheezing, atopy, maternal smoking, and number of fever episodes. This paper discusses the burden, prevalence, and risk factors associated with paediatric asthma.
Acne appears to represent a visible indicator disease of over-activated mTORC1 signalling, an unfavour-able metabolic deviation on the road to serious common Western diseases of civilisation associated with increased body mass index and insulin resistance. Exaggerated mTORC1 signalling by Western diet explains the association of acne with increased body mass index, insulin resistance, and early onset of menarche. Both, a high glycaemic load and increased consumption of milk and milk products, staples of Western diet, aggravate mammalian target of rapamycin complex 1 signalling. This review of the literature summarises present evidence for an association between acne, increased body mass index, insulin resistance and Western diet. By dietary intervention with a Palaeolithic-type diet, the dermatologist has the chance to attenuate patients' increased mTORC1 signalling by reducing glycaemic load and milk consumption, which may not only improve acne but may delay the march to more serious mTORC1-driven diseases of civilisation.
The prevalence of allergic diseases has increased in recent decades. Allergic diseases, particularly asthma, are complex diseases with strong gene-environment interactions. Epidemiological studies have identified a variety of risk factors for the development of allergic diseases. Among them, endocrine-disrupting chemicals (EDCs) play an important role in triggering or exacerbating these diseases. 4-Nonylphenol (NP) and 4-octylphenol (OP)--two major alkylphenols--have been recognized as common toxic and xenobiotic endocrine disrupters. Due to their low solubility, high hydrophobicity, and low estrogenic activity, they tend to accumulate in the human body and may be associated with the adverse effects of allergic diseases. Recently, new evidence has supported the importance of alkylphenols in the in vitro allergic response. This review focuses on the effects of alkylphenols on several key cell types in the context of allergic inflammation. Copyright © 2012. Published by Elsevier B.V.
Nineteen people without prior history of documented heart disease were studied for 8 months to determine the effect of treatment based on an immunologic unified theory of vascular disease. Subjects underwent myocardial perfusion imaging to quantify the extent and severity of coronary artery disease, along with assessment of wall motion abnormalities and ejection fraction by both nuclear and echocardiographic methods. These tests were repeated at the end of the study. Treatment consisted of dietary changes, treatment of cholesterol, triglycerides, homocysteine, lipoprotein (a), fibrinogen, C-reactive protein, and infection. Patients who followed the dietary recommendations demonstrated statistically reduced disease in all three major coronary arteries, whereas those individuals who followed high-protein diets demonstrated statistically greater levels of disease.
BACKGROUND/OBJECTIVES: Vegetarian diet has become an increasing trend in western world and in Poland. The frequency of allergies is growing, and the effectiveness of vegetarian diet in allergic diseases is a concern for research. We aimed to study an effect of vegetarian diet on lipid profile in serum in a group of Polish children in Poland and to investigate lipid parameters in healthy vegetarian children and in omnivorous children with diagnosed atopic disease. SUBJECTS/METHODS: Serum lipid profiles (triglycerides, total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, fatty acids) were assessed in groups of children: healthy vegetarians (n=24) and children with diagnosed atopic diseases (n=16), with control group of healthy omnivores (n=18). Diet classification was assessed by a questionnaire. RESULTS: No differences were observed in serum triglycerides, LDL cholesterol and saturated and monounsaturated fatty acids level in all groups. In the group of Polish vegetarian children, we recorded high consumption of vegetable oils rich in monounsaturated fatty acid, and sunflower oil containing linoleic acid. This observation was associated with higher content of linoleic acid in serum in this group. Among polyunsaturated n-6 fatty acids, linoleic acid revealed significantly (P<0.05) lower levels in allergy vs vegetarian groups. In case of eicosapentaenoic acid (n-3 fatty acid), the allergy group showed higher levels of this compound in comparison to vegetarians. CONCLUSIONS: Significantly higher concentration of linoleic acid in vegetarian children in comparison to allergy group indicated possible alternative path of lipid metabolism in studied groups, and in consequence, some elements of vegetarian diet may promote protection against allergy.
In a controlled clinical trial we have recently shown that patients with rheumatoid arthritis (RA) improved after fasting for 7-10 d and that the improvement could be sustained through 3.5 months with a vegan diet and 9 months with a lactovegetarian diet. Other studies have indicated that the inflammatory process in RA can be reduced through manipulation of dietary fatty acids. A switch to a vegetarian diet significantly alters the intake of fatty acids. Therefore, we have analysed the changes in fatty acid profiles of the plasma phospholipid fraction and related these changes to disease activity. The concentrations of the fatty acids 20:3n-6 and 20:4n-6 were significantly reduced after 3.5 months with a vegan diet (P < 0.0001 and P < 0.01 respectively), but the concentration increased to baseline values with a lactovegetarian diet. The concentration of 20:5n-3 was significantly reduced after the vegan diet (P < 0.0001) and the lactovegetarian diet periods (P < 0.01). There was no significant difference in fatty acid concentrations between diet responders and diet non-responders after the vegan or lactovegetarian diet periods. Our results indicate that the changes in the fatty acid profiles cannot explain the clinical improvement.
Chronic inhalation of cigarette smoke (CS) induces emphysema by the damage contributed by oxidative stress during inhalation of CS. Ingestion of açai fruits (Euterpe oleracea) in animals has both antioxidant and anti-inflammatory effects. This study compared lung damage in mice induced by chronic (60-day) inhalation of regular CS and smoke from cigarettes containing 100mg of hydroalcoholic extract of açai berry stone (CS + A). Sham smoke-exposed mice served as the control group. Mice were sacrificed on day 60, bronchoalveolar lavage was performed, and the lungs were removed for histological and biochemical analyses. Histopathological investigation showed enlargement of alveolar space in CS mice compared to CS + A and control mice. The increase in leukocytes in the CS group was higher than the increase observed in the CS + A group. Oxidative stress, as evaluated by antioxidant enzyme activities, mieloperoxidase, glutathione, and 4-hydroxynonenal, was reduced in mice exposed to CS+A versus CS. Macrophage and neutrophil elastase levels were reduced in mice exposed to CS + A versus CS. Thus, the presence of açai extract in cigarettes had a protective effect against emphysema in mice, probably by reducing oxidative and inflammatory reactions. These results raise the possibility that addition of açaí extract to normal cigarettes could reduce their harmful effects. Copyright © 2010 Elsevier Ltd. All rights reserved.
In a controlled, single blind clinical trial we have demonstrated recently a beneficial effect of fasting and vegetarian diet in RA. In the present study we compared 53 patients who participated in this clinical trial with 71 other RA patients with regard to some psychological parameters. The patients who participated in the clinical trial differed significantly from other RA patients. Firstly, they had a higher internal score and a lower chance score on the Multi-dimensional Health Locus of Control Scale (MHLCS). Secondly, their belief in the effect of ordinary medical treatment, evaluated by a 10-cm visual analogue scale, was lower, and their belief in the effect of 'alternative', unconventional forms of treatment was higher. Of the patients who were randomized to a vegetarian diet, there was no significant difference between diet responders and diet non-responders with regard to the MHLCS scores. But, diet responders had a significantly lower belief in the effect of ordinary medical treatment compared with diet non-responders. The psychological distress imposed on the patients by changing from an omnivorous diet to a vegetarian diet was monitored during the clinical trial by means of the General Health Questionnaire. Throughout the clinical trial, this variable favoured the vegetarians compared with the omnivorous and the diet responders vs the diet non-responders. We conclude, firstly, that patients with certain psychological characteristics were selected to the clinical trial; secondly, that the MHLCS scores could not explain the clinical improvement, but it may have been influenced by the patients' beliefs in ordinary and 'alternative' forms of treatment; and thirdly, that dietary treatment decreased psychological distress.
BACKGROUND: The regulatory function of the endothelium is altered in hypercholesterolemia, and the subsequent endothelial dysfunction plays a central role in the development of atherosclerosis. OBJECTIVE: To determine whether endothelial function in hypercholesterolemic patients is affected by replacing a saturated fat-enriched diet with a low-fat, low-saturated fat diet (the U.S. National Cholesterol Education Program stage 1 [NCEP-1] diet) or a diet rich in monounsaturated fat (such as that common in Mediterranean countries). DESIGN: Intervention dietary study with a baseline phase and two randomized crossover dietary periods. SETTING: Hospital Universitario Reina Sofía, Córdoba, Spain. PATIENTS: 22 hypercholesterolemic men. INTERVENTION: Patients followed a diet high in saturated fat, then were assigned in a crossover design to the NCEP-1 diet or a Mediterranean diet. Each dietary period lasted 28 days. MEASUREMENTS: Plasma P-selectin levels, lipid concentrations, and endothelial function. RESULTS: Compared with the saturated fat diet, flow-mediated dilatation increased during the Mediterranean diet but not during the NCEP-1 diet. In addition, levels of plasma cholesterol, low-density lipoprotein cholesterol, apolipoprotein B, and P-selectin decreased during the NCEP-1 and Mediterranean diets. CONCLUSION: In hypercholesterolemic men, diets low in fat (especially saturated fat) and diets rich in monounsaturated fats improve endothelial function.
Background Dietary fat exerts numerous complex effects on proinflammatory and immunologic pathways. Several epidemiological studies have examined the relationships between intake of fatty acids and/or foods high in fat and allergic rhinitis, but have provided conflicting findings. The current cross-sectional study investigated such relationships in Japan. Methods Study subjects were 1745 pregnant women. The definition of rhinoconjunctivitis was based on criteria from the International Study of Asthma and Allergies in Childhood. Information on dietary factors was collected using a validated self-administered diet history questionnaire. Adjustment was made for age; gestation; region of residence; number of older siblings; number of children; smoking; secondhand smoke exposure at home and at work; family history of asthma, atopic eczema, and allergic rhinitis; household income; education; and body mass index. Results The prevalence of rhinoconjunctivitis in the past 12 months was 25.9%. Higher meat intake was significantly associated with an increased prevalence of rhinoconjunctivitis: the adjusted odds ratio between extreme quartiles was 1.71 (95% confidence interval: 1.25-2.35, P for trend = 0.002). No measurable association was found between fish intake and rhinoconjunctivitis. Intake of total fat, saturated fatty acids, monounsaturated fatty acids, n-3 polyunsaturated fatty acids, α-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid, n-6 polyunsaturated fatty acids, linoleic acid, arachidonic acid, and cholesterol and the ratio of n-3 to n-6 polyunsaturated fatty acid intake were not evidently related to the prevalence of rhinoconjunctivitis. Conclusions The current results suggest that meat intake may be positively associated with the prevalence of rhinoconjunctivitis in young adult Japanese women.
Experiences with food intake, diet manipulations and fast were registered in rheumatic patients. The study was a questionnaire-based survey in which 742 patients participated. It comprised 290 patients with rheumatoid arthritis, 51 patients with juvenile rheumatoid arthritis, 87 patients with ankylosing spondylitis, 51 patients with psoriatic arthropathy, 65 patients with primary fibromyalgia and 34 patients with osteoarthritis. One third of the patients with rheumatoid arthritis, ankylosing spondylitis and psoriatic arthropathy reported aggravation of disease symptoms after intake of certain foods while 43% of the patients with juvenile rheumatoid arthritis and 42% of the patients with primary fibromyalgia stated the same. Twenty-six percent of the patients with juvenile rheumatoid arthritis and 23% of the patients with rheumatoid arthritis, ankylosing spondylitis and primary fibromyalgia had previously tried certain diets in the attempt to alleviate disease symptoms, whereas 13% of the patients with psoriatic arthropathy and 10% with osteoarthritis had tried diet therapy. Less pain and stiffness were reported by 46% of the patients and 36% reported reduced joint swelling. Similar beneficial effects of diet were also reported in other rheumatic disease groups. Fifteen percent of the patients with rheumatoid arthritis and ankylosing spondylitis had been through a fasting period. Less pain and stiffness were reported by 2/3 of the patients in both groups and half of the patients in both groups reported a reduced number of swollen joints.
A 5-year-old boy with autism developed dry eye and xerophthalmia. Serum vitamin A was undetectable. Dietary history revealed a markedly altered intake consisting of only fried potatoes and rice balls for 2 years. Fried potatoes contain no vitamin A. Autism is a multifaceted developmental disorder infrequently accompanied by abnormal eating practices. To the authors' knowledge, most children with autism who develop dietary vitamin A deficiency have consumed an excess of fried potatoes. Attention to possible vitamin A deficiency is essential when fried potatoes are consumed exclusively.
Annatto dye is an orange-yellow food coloring extracted from the seeds of the tree Bixa orellana. It is commonly used in cheeses, snack foods, beverages, and cereals. Previously reported adverse reactions associated with annatto dye have included urticaria and angioedema. We present a patient who developed urticaria, angioedema, and severe hypotension within 20 minutes following ingestion of milk and Fiber One cereal, which contained annatto dye. Subsequent skin tests to milk, wheat, and corn were negative. The patient had a strong positive skin test to annatto dye, while controls had no response. The nondialyzable fraction of annatto dye on SDS-PAGE demonstrated two protein staining bands in the range of 50 kD. Immunoblotting demonstrated patient IgE-specific for one of these bands, while controls showed no binding. Annatto dye may contain contaminating or residual seed proteins to which our patient developed IgE hypersensitivity. Annatto dye is a potential rare cause of anaphylaxis.
