The NIH Pediatric Allergy Clinic has provided residents in the NIAID Allergy and Immunology Clinical Fellowship Program with medical training and continuity clinic experience in pediatric allergic diseases including asthma, allergic rhinitis, food allergy, atopic dermatitis and urticaria. During the past fiscal year, patient care visits exceeded 350, with a total accrual of 260 new patients. The NIH Pediatric Allergy Clinic also provides clinical resources for the study of children with allergic inflammatory disorders. In addition to standard diagnostic testing for allergic diseases, which includes skin prick testing, radioallergosorbent (RAST) testing, patch testing and pulmonary function testing, the clinic has integrated other modalities in the evaluation of children with allergic diseases. To evaluate lung function we have emplotyed impulse oscillometry, a non-invasive, non-effort dependant technique that measures lung resistance and elasticity. This is being used in conjunction with standard pulmonary function testing in older children and by itself in infants as young as two years old. A manuscript reviewing the clinical application of impulse oscillometry in pediatric patients with asthma is being prepared for publication. Through consultation with the NHLBI pulmonology service, exercise challenge pulmonary function testing has been performed. In conjunction with other investigators in the LAD, expired breath condensate and exhaled nitric oxide measurements have been obtained for diagnostic and research purposes. Research blood has been collected for laboratory studies to measure markers of allergic diseases, develop approaches to culture mast cells from blood, and determine cytokine and signaling profiles. In particular, serum tryptase levels were measured in 44 non-atopic and 153 atopic clinic patients. Median and 95% prediction intervals of tryptase levels for non-atopics were 3.44, 0.64-6.77 and 3.56, 0.98-10.80 for atopics. This study, recently published in the Journal of Allergy and Clinical Immunology (9 August 2009 on-line) establishes normative serum reference tryptase values in atopic and non-atopic children. Among atopics, a statistically significant association with tryptase was found for gender and race but not for ethnicity, total IgE levels, weight/weight percentile or eczema status. Patient documentation for communication with referring physicians and for longitudinal analysis is entered into CRIMSON, the NIAID database system.

美国国立卫生研究院儿科过敏诊所为NIAID过敏和免疫学临床奖学金项目的住院医师提供儿科过敏疾病的医学培训和持续的临床经验，包括哮喘，过敏性鼻炎，食物过敏，特应性皮炎和荨麻疹。在过去的财政年度，病人的护理次数超过350次，总共增加了260名新病人。美国国立卫生研究院儿童过敏诊所还为过敏性炎症疾病儿童的研究提供临床资源。
