Del Pozo MD, Audícana M, Diez JM, Muñoz D, Ansotegui IJ, Fernández E, García M, Etxenagusia M, Moneo I, Fernández de Corres L. Anisakis simplex , a relevant etiologic factor in acute urticaria.
Anisakis simplex , a parasite of fish and cephalopods, can induce IgE-mediated reactions. This study aimed to determine the etiologic role of A. simplex in patients affected by urlicaria/angioedema 'AE' or anaphylaxis. We studied 100 adult subjects suffering acute episodes of urticaria/AE, by anamnesis, prick tests with A. simplex and fish-mix extracts, and total and specific IgE to both A. simplex and cod. The following criteria of A. simplex allergy were considered: 1' urticaria/AE within 6 h after fish ingestion; 2' specific IgE to A. simplex; 3' positive prick test to A. simplex extract; 4' exclusion of other suspected causes. Double-blind, placebo-controlled food challenge was not carried out because ethical considerations forbid challenge with a parasite. Specific IgE to A. simplex '<0.7 kU/1' was found in 22 subjects, but only eight were diagnosed as having A. simplex allergy. Other allergens were involved in 37 patients, and 55 cases were considered idiopathic. Specific IgE to fish '<0.7 kU/1' was found in two patients, but only one was diagnosed as having fish allergy. We concluded that A. simplex is an important etiologic factor in acute urticaria. We suggest that it should be considered in cases of urticaria/AE or anaphylaxis, especially after fish ingestion. 相似文献

OBJECTIVE: This study examined the predictive factors for the physical and mental summary components (PCS and MCS) of quality of life (SF-36) in patients with anorexia nervosa. METHOD: Forty-seven patients with anorexia nervosa were studied. Assessment comprised psychiatric diagnosis by a clinical structured interview for Axis I disorders (SCID-I) and personality disorders (SCID-II), Clinical Global Impression (CGI), and Quality of Life (SF-36). RESULTS: Anorexia nervosa, restrictive type, was diagnosed in 73.9% of the patients and 51% of the patients presented with comorbidity on Axis I or Axis II or both. The predictive variables for the PCS were poor outcome in previous year, comorbidity on Axes I and II, and female gender. The predictive variables for the MCS were the presence of comorbidity in one or the other of the Axis I or II disorders and purging behaviors. DISCUSSION: The current study suggests the importance of comorbidity and purging behaviors in the quality of life of these patients with anorexia nervosa. 相似文献

BACKGROUND: Mercury derivatives are frequent contact allergens and their cross-reactivity is not constant. Thimerosal is an organic mercurial used as an antiseptic and as a preservative in most vaccines. OBJECTIVE: To evaluate cross-reactivity, exposure factors, and tolerance to vaccines containing thimerosal in patients sensitized to mercury derivatives. METHODS: Design: Observational study (cross-sectional); Patients: 125 patients were recruited for the study, 72 women and girls and 53 boys and men, average age 18.7 years old, range 3 to 65, with positive patch tests to mercury derivatives and/or thimerosal; Interventions: All patients were studied by means of enquiry, patch tests, intradermal tests, and intramuscular challenge with thimerosal. RESULTS: A sensitization to thimerosal was observed in 57 patients. Twenty-four of these 125 patients presented a positive intradermal reaction. Ammoniated mercury seems to be a good marker of mercury sensitization eliciting positive reaction in 78% of all patients and merbromin in 66%. In most cases, (100/125) cross-reactivity was found among mercury derivatives. The intramuscular injection of thimerosal induced a mild local reaction in only 5 patients (4% of the total, 9% of thimerosal positive reactions). Childhood vaccinations, merbromin used as an antiseptic, broken thermometers, and the use of drops were the main sources of exposure. CONCLUSIONS: The majority of the patients showed positive tests to both organic and inorganic mercury derivatives. Vaccination with thimerosal is relatively safe, even for individuals with delayed type hypersensitivity to this chemical, since more than 90% of allergic patients tolerated intramuscular challenge tests with thimerosal. A simplified protocol of patch tests to study mercury derivatives is proposed. It would be advisable to restrict the use of mercurial antiseptics and mercury thermometers. 相似文献

Background: In Mexico, breast cancer (BCa) is in first place regarding cancer mortality and has been established as a priority health issue. The incidence of metastasis from BCa is very high and presents as the principal mortality factor among women younger than 40 years of age. OBJECTIVE. To determine any associations between clinicopathological characteristics and metastasis in Mexican women under 40 years of age. Methods: During the 2010–2015 period, a total of 180 female BCa cases seen at the Navy General High Specialty Hospital, SEMAR, in Mexico City; we collected information on 20 patients with BCa younger than 40 years of age. Statistical analyses were conducted using the Kolmogorov–Smirnov, Students t, Fisher, Chi square, and Mantel–Haenszel tests. Results: The prevalence of women with BCa younger than the age of 40 years during the 2010–2015 period was 13.3%. We found a high frequency of obesity in of these cases (>75%); 100% of obese patients with a history of smoking presented with metastasis (p <0.05). In addition, the hormone phenotype was important; HER2-positive cases were 12 times more likely tto exhibit metastasis (p <0.05), while expression of estrogen and progesterone receptors appeared to be protective. Diabetes mellitus in combination with smoking was also a risk factor for development of metastasis (p <0.05). Conclusion: In this study, we obtained essential data regarding risk of metastasis in young breast cancer cases which could be useful for predicting disease evolution and treatment response. 相似文献

28 patients with dermatitis from plants were seen over the last 10 years. This was 1.45% of all patients with contact dermatitis. 7 reacted to Frullania , 4 to Compositae. and 1 to helenin. Patch tests with Frullanaceae, Lauraceae, Magnoliaceae, Compositae and helenin, showed no dominant allergen in the plant families with sesquiterpene lactone sensitivity. The positive reactions with feverfew ( Chrysanthemum parthenium ) in nearly all patients is probably due to the high content of the sesqueterpene lactone parthenolide; it is a better screening allergen for Compositae sensitivity than alantolactone (helenin). 相似文献

Allergic reactions to betalactams: studies in a group of patients allergic to penicillin and evaluation of cross-reactivity with cephalosporin 总被引:1,自引:5,他引:1

A group of 34 penicillin-allergic patients was studied to determine skin test reactivity to the different penicillins involved in inducing the allergic reaction and the cross-reactivity with side-chain-related and side-chain-unrelated cephalosporins. All the subjects selected for the study had to be skin test positive to at least one of the following determinants: benzyl-penicilloyl-polylysine (BPO-PLL), minor-determinant mixture (MDM), amoxicillin (AX), or ampicillin (AMP), or to possess in vitro IgE to the following conjugates: benzyl-penicilloyl-human-serum albumin (BPO-HSA), ampicilloyl-human-serum albumin (AMP-HSA), and amoxicilloyl-human-serum albumin (AX-HSA). Cephalexin (CE) and ceftazidime (CEF) were used to assess cross-reactivity. If skin tests to any of these compounds were positive, the patient was considered to be allergic; if negative, a challenge test was performed. Sixteen patients (47%) were skin test positive to BPO and/or MDM, and nine (26%) exclusively to AX and/or AMP. In three cases (8%), the RAST was positive although the skin test was negative; one to BPO-HSA and two to AX-HSA and AMP-HSA. Six patients (17%) needed to be challenged with the penicillin involved to establish the diagnosis. In five patients (14%), the skin tests were positive to CE and in none to CEF. In all the others, the skin tests were negative to both cephalosporins, and the patients tolerated the drugs when challenged. These results indicate the relevance of side-chain-specific minor determinants in betalactams allergy and provide support for the role of this chemical structure in the evaluation of cross-reactivity between penicillins and cephalosporins. 相似文献

Twenty blood donors developed a dermatitis at the site of venesection within a few hours of giving blood. A local anaesthetic administered with a Dermo-Jet had been used before extracting blood. In only 2 cases was sensitivity to the local anaesthetic found. In the others the reaction was caused by nickel released from the Dermo-Jet. The quantity of nickel released is greater from the anaesthetic solution than from deionised water. It increases with the time that the anaesthetic remains in the Dermo-Jet. The release of nickel is greater from a used Dermo-Jet than from a new one. Histology revealed a lymphohistiocytic infiltrate at the level of the deep dermis. 相似文献
