Sputum eosinophilia: an early marker of bronchial response to occupational agents

Abstract: An increase in sputum eosinophils is an early marker of specific bronchial reactivity to occupational agents, which may help to identify subjects who will develop an asthmatic reaction only after repeated exposure.

“…Recent prospective data indicate that an increase in sputum eosinophils is an early marker of specific bronchial reactivity to occupational agents and may help to identify subjects who will develop an asthmatic reaction after repeated challenge exposure [81]. A .3% absolute increase in sputum eosinophils as compared to baseline after a 2-h challenge yielded a sensitivity of 67% and a specificity of 97% in predicting the development of an asthmatic response on subsequent challenge(s) [81]. A post-challenge increase in sputum neutrophil count has also been documented [81,82], especially after exposure to LMW agents [83,84].…”

A post-challenge increase in sputum neutrophil count has also been documented [81,82], especially after exposure to LMW agents [83,84]. However, the interpretation of changes in sputum neutrophil counts has not yet been further validated.…”

“…В недавнем проспективном исследо вании показано, что увеличение числа эозинофилов в мокроте является ранним маркером специфичес кой бронхиальной реактивности на производствен ные вещества, что помогает выделить лиц, у которых после повторных провокационных тестов может раз виться астматическая реакция [81]. Увеличение аб солютного числа эозинофилов в мокроте ≥ 3 % по сравнению с исходным уровнем через 2 ч после тес тирования обладает чувствительностью 67 % и спе цифичностью 97 % для прогнозирования астмати ческой реакции при последующих провокационных тестах [81]. Также описано повышение числа нейт рофилов в мокроте после провокационных тестов [81,82], особенно после воздействия низкомолекуляр ных веществ [83,84].…”

Однако значение этого явления пока не определено.…”
