Clinical and laboratorial investigation in patients with suspected drug allergy in a tertiary hospital / InvestigaÃÃo clÃnico laboratorial de pacientes com suspeita de reaÃÃes de hipersensibilidade alÃrgica a fÃrmacos em hospital terciÃrioLuciana Mabel Ferreira Vasconcelos 19 January 2012 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Allergic drug reactions account for 6.5% of hospital admissions, prolonged hospitalization 15.1% of patients and are severe in 6.7% of patients. There are difficulties in understanding the immune mechanisms, diagnosis and treatment of patients. Therefore, such reactions are considered a Public Health problem. The objective of this study was to describe the cases of patients with suspected allergic hypersensitivity to drugs and to evaluate the response of individuals to skin tests. A total of 63 patients were included in the study. The experimental design was a cross-sectional observational study from June 2008 to October 2011. We applied a questionnaire to investigate the clinical and laboratory informations. Eight patients received other diagnosis and three died due to other reasons, so that 52 patients completed the study. Most patients were men (56.36%), non atopic, with a median age of 52 year. The drugs most commonly implicated were NSAIDs and the oral administration was the most commonly route used. It was documented 69 suspected reactions; most of them were considered as delayed hipersensitivity. Maculopapular rash and erythema multiforme were the most frequent manifestations. According to the severity of the reactions, most was considered moderate (72.46%). The patch test was performed in 22 patients for investigation of delayed reaction. Seven cases were positive (31.81%), DRESS (rash with eosinophilia and systemic symptoms) caused by captopril (+), contact eczema by rifamycin (+ +), lichenoid eruption by captopril (+), maculopapular rash + ampicillin and cephalexin to angioedema (+), two cases of fotoeczema one by captopril and another by AAS, both with positive results (+) and one case of Stevens-Johnson syndrome caused by phenytoin (++). For immediate hypersensitivity, 3 in 10 patients have shown positive results for prick test with AAS diluted to 1/1000. It was possible to confirm the liability of the drug reactions in 19 (27.53%), which demonstrated the importance of application of skin tests in the clinical investigation of allergic drug reactions. As for causality, 26 reactions were considered possible, 20 defined, 13 probable, 9 and a conditional reaction was considered not related to drugs. Given its importance, the performance of skin tests with these patients has opened perspectives on the possibility to incorporate this service in routine outpatient Dermatology HUWC. / As reaÃÃes alÃrgicas medicamentosas sÃo responsÃveis por 6,5% das admissÃes hospitalares, prolongam a hospitalizaÃÃo de 15,1% dos pacientes e sÃo graves em 6,7% dos pacientes. Hà dificuldades quanto à compreensÃo dos mecanismos imunolÃgicos, diagnÃstico e tratamento dos pacientes. Portanto, tais reaÃÃes sÃo consideradas um problema de saÃde pÃblica. O objetivo deste trabalho foi descrever os casos de pacientes com suspeita de hipersensibilidade alÃrgica a fÃrmacos e avaliar a resposta desses indivÃduos aos testes cutÃneos. Um total de 63 pacientes foram incluÃdos no trabalho, cujo delineamento experimental foi de um estudo observacional descritivo transversal realizado entre junho de 2008 e outubro de 2011. Utilizou-se um questionÃrio para investigaÃÃo das informaÃÃes clÃnico-laboratoriais. Oito pacientes receberam outro diagnÃstico e trÃs foram a Ãbito por outros motivos, de forma que 52 pacientes completaram o estudo. A maioria dos pacientes era homem (56,36%), nÃo atÃpicos, com mediana de idade de 52 anos. Os fÃrmacos mais implicados foram os AINES (anti-inflamatÃrios nÃo esteroidais) e a via oral foi a mais utilizada. Foram documentadas 69 reaÃÃes suspeitas, a maioria do tipo tardia. Exantema maculopapuloso e eritema multiforme foram as manifestaÃÃes mais freqÃentes entre as reaÃÃes tardias. Quanto à gravidade, a maioria foi considerada moderada (72,46%). O teste de contato foi realizado em 22 pacientes para investigaÃÃo de reaÃÃo tardia. Em sete casos, houve resultado positivo (31,81%), ou seja, DRESS (Rash com eosinofilia e sintomas sistÃmicos) causado por captopril (+), eczema de contato por rifamicina (++), erupÃÃo liquenÃide por captopril (+), exantema maculopapuloso + angiodema para cefalexina e ampicilina (+), dois casos de fotoeczema, um por captopril e outro por Ãcido acetilsalicÃlico (AAS), ambos com resultado (+) e um caso de sÃndrome de Steven-Johnson por fenitoÃna (++). Foram realizados dez testes de puntura e em trÃs pacientes houve positividade para AAS diluÃdo a 1/1000. Foi possÃvel confirmar a imputabilidade do fÃrmaco em 19 reaÃÃes (27,53%), o que demonstra a importÃncia da aplicaÃÃo dos testes cutÃneos na investigaÃÃo clÃnica das reaÃÃes alÃrgicas a medicamentos. Quando à causalidade, 26 reaÃÃes foram consideradas possÃveis, 20 definidas, 13 provÃveis, 9 condicionais e uma reaÃÃo foi considerada nÃo relacionada com fÃrmacos. Dada a sua importÃncia, a realizaÃÃo dos testes cutÃneos com esses pacientes abriu perspectivas sobre a possibilidade incorporar esse serviÃo na rotina do ambulatÃrio de Dermatologia do HUWC.

Development of method to assess skin contact to chemicalsReed, Susan, University of Western Sydney, Hawkesbury, College of Science, Technology and Environment January 2001 (has links)
Chemical exposure of the skin has become a route of entry of some chemicals into the body and has come under major review in recent times. This research aims to develop a method of estimating skin exposure that is both reliable and non-prohibitive in cost. This involved the design and testing of skin patches adaptable for monitoring skin exposure to chemicals using several different types of absorbents which could be easily worn against skin. The final design of the patch used either activated charcoal or tenax as the absorbing medium. The patches were then desorbed with a solvent in order to analyse the chemicals. The results of the study showed that many skin exposures do not have a direct relationship with inhalation exposures, which is important because currently there are no estimates of the levels of skin exposures that may have potential long term health effects. The patch has proved successful for detecting the presence and determining the amount of chemicals that come in contact with the skin. Charcoal patches have the widest application, but are not suitable for all situations and tenax should be used on these occasions. / Doctor of Philosophy (PhD)

Sensibilização a alérgenos alimentares na doença do refluxo gastroesofágico refratária ao tratamento convencional / Sensitization to food allergens in patients with gastroesophageal reflux disease refractory to conventional treatmentPomiecinski, Fabiane 08 July 2010 (has links)
Introdução: A doença do refluxo gastroesofágico (DRGE) refratária pode estar relacionada à maior sensibilização a alimentos pelo dano ácido-péptico às junções intercelulares e/ou pelo aumento do pH gástrico pelos inibidores de bomba de prótons (IBPs). A falha na resposta ao tratamento da DRGE tem sido atribuída, entre outras causas, à esofagite eosinofílica (EE). Objetivo: O objetivo principal do estudo foi avaliar a sensibilização a alimentos nos pacientes com DRGE refratária. Como objetivos secundários, comparamos as características dos pacientes sensibilizados com os não sensibilizados e verificamos a resposta clínica da DRGE à dieta de restrição aos alimentos aos quais o paciente estava sensibilizado. Métodos: Os pacientes com DRGE refratária realizaram dieta de restrição baseada no resultado de teste cutâneo de leitura imediata (TCLI) e teste cutâneo de contato (TCC) com alimentos. As características dos pacientes sensibilizados foram comparadas com os não sensibilizados com relação à atopia e número de eosinófilos na mucosa esofágica. Resultados: A prevalência de sensibilização a alimentos nos pacientes com DRGE refratária foi de 27,7%, sendo 15,3% pelo TCLI e 12,3% pelo TCC. Os asmáticos apresentaram maior sensibilização a alimentos (p=0,008). Foi identificada a presença de eosinófilos na mucosa esofágica em 15,8% dos pacientes e esta correlacionou-se com maior sensibilização a alimentos (p=0,011). Foi confirmado um caso de EE. A dieta de exclusão aos alimentos identificados promoveu melhora clínica dos sintomas da DRGE (p=0,004). Conclusão: A presença de eosinófilos na mucosa esofágica associada à maior sensibilização a alimentos e a resposta à dieta de exclusão em pacientes com testes positivos sugere que a DRGE refratária pode representar um estágio inicial da EE. / Abstract: Refractory gastroesophageal reflux disease (GERD) can be related to greater sensitization to foods due to peptic acid damage to intercellular junctions and/or due to the increase in gastric pH by proton pump inhibitors (PPIs). The lack of response to treatment of GERD has been attributed to, among other causes, eosinophilic esophagitis (EE). Objective: The principal objective of the study was to evaluate the sensitization to foods in patients with refractory GERD. As secondary objectives, we compared the characteristics of sensitized patients with those non-sensitized and found a clinical response of GERD to a diet restricting foods to which the patient was sensitized. Methods: Patients with refractory GERD were put on a restriction diet based on the results of skin prick test (SPT) and atopy patch test (APT) with foods. The characteristics of the sensitized patients were compared to those non-sensitized in relation to atopia and number of eosinophils in the esophageal mucosa. Results: The prevalence of sensitization to foods in patients with refractory GERD was 27.7%, where 15.3% were determined by SPT and 12.3% by APT. Asthmatics showed higher sensitization to foods (p=0.008). The presence of eosinophils in the esophageal mucosa was determined in 15.8% of patients, and this correlated with greater sensitization to foods (p=0.011). One case of EE was confirmed. A diet excluding identified sensitizing foods led to clinical improvement with regard to GERD symptoms (p=0,004). Conclusion: The presence of eosinophils in esophageal mucosa associated with greater sensitization to foods and the response to restriction diet in patients with positive tests suggest that refractory GERD can represent an initial stage of EE.
