Plasma interferon predicts pulmonary hypertension severity and outcome

Area of Science:

• Immunology
• Pulmonology
• Biomarker Discovery

Background:

• Pulmonary hypertension (PH) is a progressive disease where inflammation plays a key role.
• Interferons (IFNs) are immune cytokines involved in cellular responses.
• This study investigated the link between IFN levels and PH risk and prognosis.

Purpose of the Study:

• To determine the association between interferon levels and the risk of developing pulmonary hypertension.
• To evaluate the prognostic value of interferon levels in patients with pulmonary hypertension.
• To explore the potential of interferons as biomarkers in PH.

Main Methods:

• A cohort study included 875 PH patients and 182 controls.
• Logistic regression and ROC curves assessed PH risk association with IFN levels.
• Cox regression and Kaplan-Meier curves evaluated prognostic value; a nomogram was constructed.

Main Results:

• Interferon-alpha (IFN-α) and IFN-γ levels were significantly higher in PH patients.
• IFN-α showed stronger predictive value, especially in Group 4 PH and IPAH.
• Elevated IFN-α levels were linked to lower survival rates in PH patients.

Conclusions:

• Plasma IFN-α is a potential biomarker for predicting PH risk.
• IFN-α levels can aid in assessing the prognosis of pulmonary hypertension.
• Combining IFN-α with clinical markers improves PH risk stratification.
