Introducción: La Fracción Exhalada de Óxido Nítrico (FeNO) ha sido propuesta como biomarcador no invasivo de inflamación eosinofílica, pero su utilidad diagnóstica para predecir el control del asma sigue siendo debatida. Objetivo: Evaluar la capacidad predictiva de la FeNO para identificar el control clínico del asma en adultos basado en el Asthma Control Test (ACT). Metodología: Estudio de prueba diagnóstica a partir de una base de datos de pacientes adultos con asma atendidos entre 2021 y 2024. Se incluyeron pacientes ≥18 años con diagnóstico de asma y datos simultáneos de ACT y FeNO. Se evaluó la capacidad diagnóstica de la FeNO para identificar el control del asma (ACT ≥20), mediante estimaciones de sensibilidad, especificidad, razones de verosimilitud y AUC-ROC. Análisis en STATA v14.0 (α = 0,05). Aprobación del comité de ética: CIE-072-2024. Resultados: Se incluyeron 401 pacientes adultos con diagnóstico de asma, de los cuales el 67% presentaba asma no controlada según el ACT. No se observaron diferencias estadísticamente significativas en los niveles de FeNO entre los grupos con y sin control clínico del asma, independientemente del punto de corte utilizado (40 ppb: 32,8% vs. 37,5%, p = 0,363; 50 ppb: 23,9% vs. 29,6%, p = 0,228). La correlación entre FeNO y la puntuación ACT fue muy baja y no significativa (r = 0,01; p = 0,83), con un bajo poder discriminativo (AUC = 0,52). En cambio, se identificó una correlación positiva y significativa entre niveles elevados de FeNO y marcadores de inflamación tipo 2, como eosinofilia periférica (r = 0,19; p = 0,0085) e hiperreactividad bronquial (r = 0,18; p = 0,0003). Conclusión: La FeNO no demostró utilidad como marcador del control clínico del asma medido por el ACT, debido a su bajo rendimiento discriminativo. No obstante, si se evidenció una asociación con la eosinofilia periférica y la hiperreactividad bronquial. |

Objective: To evaluate the predictive capacity of FeNO to identify clinical asthma control in adults, based on the Asthma Control Test (ACT). Methodology: A diagnostic test study was conducted using a database of adult asthma patients seen between 2021 and 2024. Individuals aged ≥18 years with a clinical or functional diagnosis of asthma and simultaneous FeNO and ACT measurements were included. The diagnostic performance of FeNO in detecting asthma control (defined as ACT ≥20) was assessed through sensitivity, specificity, likelihood ratios, and area under the ROC curve (AUC), using STATA v14.0 (α = 0.05). Ethics Committee Approval: CIE-072-2024. Results: A total of 401 adults with asthma were included, of whom 67% were classified as having uncontrolled asthma according to the ACT. No statistically significant differences in FeNO levels were found between patients with and without asthma control, regardless of the cutoff point used (40 ppb: 32.8% vs. 37.5%, p = 0.363; 50 ppb: 23.9% vs. 29.6%, p = 0.228). The correlation between FeNO and ACT scores was negligible and not statistically significant (r = 0.01; p = 0.83), with low discriminatory ability (AUC = 0.52). Nonetheless, a significant positive correlation was observed between elevated FeNO levels and markers of type 2 inflammation, such as peripheral eosinophilia (r = 0.19; p = 0.0085) and bronchial hyperreactivity (r = 0.18; p = 0.0003). Conclusion: FeNO showed limited utility as a marker of clinical asthma control as assessed by the ACT, due to its poor discriminatory capacity. However, it was significantly associated with indicators of type 2 inflammation, such as peripheral eosinophilia and bronchial hyperreactivity.Modalidad Presencialapplication/pdfspahttp://creativecommons.org/licenses/by-nc-nd/2.5/co/Abierto (Texto Completo)Atribución-NoComercial-SinDerivadas 2.5 Colombiahttp://purl.org/coar/access_right/c_abf2Capacidad predictiva de la fracción exhalada de óxido nítrico para el control del asma en adultosPredictive Capacity of Fractional Exhaled Nitric Oxide for Asthma Control in AdultsEspecialista en Medicina InternaUniversidad Autónoma de Bucaramanga UNABFacultad Ciencias de la SaludEspecialización en Medicina InternaEMIN-1050info:eu-repo/semantics/masterThesisTesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/redcol/resource_type/TMInternal medicineMedicineMedical sciencesHealth sciencesAsthmaBiomarkersFractional exhaled nitric oxideValuation studyLungs (Obstructive diseases)DemographyBronchi (Diseases)NeurotransmittersMedicina internaMedicinaCiencias médicasPulmones (Enfermedades obstructivas)DemografíaBronquios (Enfermedades)NeurotransmisoresCiencias de la saludAsmaBiomarcadoresPrueba de óxido nítrico exhalado fraccionadoEstudios de evaluación como asuntoGlobal Initiative for asthma (GINA).
