RESUMEN.<\/strong><\/p>\n

Introducci\u00f3n:<\/strong> El asma laboral es la enfermedad respiratoria ocupacional m\u00e1s frecuente en Europa y afecta especialmente a trabajadores expuestos a agentes sensibilizantes como las harinas. La identificaci\u00f3n precoz y la evaluaci\u00f3n sistem\u00e1tica desde Salud Laboral son fundamentales para establecer el diagn\u00f3stico, prevenir la progresi\u00f3n de la enfermedad y reducir su impacto funcional y laboral.<\/p>\n

Objetivos:<\/strong> Describir un caso de asma laboral en trabajador expuesto a harinas, destacando la importancia del diagn\u00f3stico precoz en el \u00e1mbito de la salud laboral.<\/p>\n

Material y M\u00e9todos:<\/strong> Se presenta el caso de un trabajador panadero con cl\u00ednica respiratoria compatible con asma, realiz\u00e1ndose estudio funcional respiratorio, registro seriado de pico flujo espiratorio y pruebas de provocaci\u00f3n bronquial.<\/p>\n

Resultados:<\/strong> La espirometr\u00eda mostr\u00f3 un patr\u00f3n obstructivo leve reversible. El registro seriado de pico flujo evidenci\u00f3 variabilidad superior al 20% con empeoramiento durante la jornada laboral. El test de provocaci\u00f3n con metacolina fue positivo y los prick-tests confirmaron sensibilizaci\u00f3n a alfa-amilasa.<\/p>\n

Conclusiones:<\/strong> La integraci\u00f3n de los hallazgos cl\u00ednicos, funcionales y laborales permiti\u00f3 confirmar el diagn\u00f3stico de asma laboral por exposici\u00f3n a harinas. El diagn\u00f3stico precoz resulta fundamental para evitar la progresi\u00f3n de la enfermedad y establecer medidas preventivas adecuadas.<\/p>\n

Title: <\/strong>OCCUPATIONAL ASTHMA DUE TO FLOUR EXPOSURE: DIAGNOSTIC CONFIRMATION BY METHACHOLINE CHALLENGE TESTING A CASE REPORT<\/strong><\/p>\n

Abstract:<\/strong><\/p>\n

Introduction:<\/strong> Occupational asthma is the most common workrelated respiratory disease in Europe, particularly among workers exposed to sensitizing agents such as flour. Early identification and systematic occupational health assessment are essential for establishing the diagnosis, preventing disease progression, and reducing its functional and occupational impact.<\/p>\n

Objectives:<\/strong> To describe a case of occupational asthma in a worker exposed to flour, highlighting the importance of early diagnosis in occupational health.<\/p>\n

Material and Methods:<\/strong> A case of a baker with respiratory symptoms suggestive of asthma is presented. Respiratory function tests, serial peak expiratory flow monitoring, and bronchial provocation testing were performed.<\/p>\n

Results:<\/strong> Spirometry showed a mild reversible obstructive pattern. Serial peak expiratory flow monitoring revealed variability greater than 20% with worsening during working hours. The methacholine challenge test was positive, and prick tests confirmed sensitization to alpha-amylase.<\/p>\n

Conclusions:<\/strong> The integration of clinical, functional, and occupational findings confirmed the diagnosis of occupational asthma due to flour exposure. Early diagnosis is essential to prevent disease progression and to implement appropriate preventive measures.<\/p>\n
