Multi-Omics Inflammatory Phenotype for ABPA Recurrence Risk Prediction

May 28, 2026 updated by: Qian Qi, Qianfoshan Hospital

Multi-Omics Data-Derived Inflammatory Phenotype for ABPA Recurrence Risk Prediction: A Multicenter Study

To develop and externally validate a machine learning model for predicting the 1-year risk of relapse in patients with stable ABPA, and to further evaluate its value in risk stratification and clinical decision-making.

Detailed Description

This project aims to develop an inflammatory phenotype-based risk prediction model for recurrence of allergic bronchopulmonary aspergillosis (ABPA) to enable stratified patient management. The study integrates multidimensional data sources, including radiomics, mycobiomics, inflammatory biomarkers, pulmonary function parameters, and routine clinical records. Deep machine learning algorithms are employed to extract and select key features from these multi-omics and clinical datasets, define inflammatory phenotypes, and subsequently construct a recurrence risk prediction model. Based on the risk stratification derived from the model, low-risk individuals will receive regular follow-up, whereas high-risk individuals will undergo intensified intervention and management. This approach is expected to optimize individualized treatment strategies for ABPA patients, reduce recurrence rates, and improve clinical outcomes.

Design Details

Cohorts and Interventions

Group / Cohort
ABPA recurrence group and No ABPA recurrence group
Patients with stable ABPA who visited multicenter hospitals between January 2021 and January 2025 were enrolled and followed up for one year. Based on the definition of ABPA relapse, they were categorized into a relapse group and a non-relapse group. Key features from medical records, inflammatory markers, fungal omics, radiomics, and pulmonary function tests were selected for model development.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recurrent disease occurs in patients during the remission period.
Time Frame: 1 year

Observe whether disease recurrence occurs in ABPA patients who have reached stable phase after treatment.

Stable Phase：

  1. Symptomatic improvement by at least 50% (on a Likert or visual analog scale) after eight weeks; and,
  2. Major radiological improvement (>50% reduction in radiologic opacities) or decline in serum total IgE by at least 20% after eight weeks of treatment.

Exacerbation/Recurrence: In a patient with diagnosed ABPA

  1. Sustained (>14 days) clinical worsening, or
  2. Radiological worsening, and
  3. Increase in serum total IgE by ≥50% from the last recorded IgE value during clinical stability, along with
  4. Exclusion of other causes of worsening.
