Clinical Scorecard: Sex Does Not Modify Asthma Attack Predictors

At a Glance

Key Highlights

• Female patients had a higher annualized severe asthma attack rate than male patients.
• Prior asthma attack history is the strongest predictor of future attacks, with sex-based differences in prognostic strength.
• Higher levels of type 2 biomarkers correlate with increased attack rates in both sexes.
• Patients with severe obesity have the highest attack rates, regardless of sex.
• Sex-stratified randomization in clinical trials may address baseline risk imbalances.

Guideline-Based Recommendations

Diagnosis

• Utilize blood eosinophil count and fractional exhaled nitric oxide for risk stratification.

Management

• Consider individual risk factors, including obesity and prior attack history, in treatment plans.

Monitoring & Follow-up

• Regularly assess asthma control and symptom scores, particularly in female patients.

Risks

• Female patients without recent attacks may still be at elevated risk for future attacks.

Patient & Prescribing Data

Patients with asthma, particularly those with severe obesity.

Inclusion of patients with severe obesity in clinical trials is essential for accurate risk assessment.

Clinical Best Practices

• Implement biomarker-guided risk stratification in clinical practice.
• Monitor female patients closely, especially those with a history of severe attacks.
