Blood Cell Count Derived Inflammatory Indexes in Acute Exacerbation of Idiopathic Pulmonary Fibrosis

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease characterized by progressive scarring. Sometimes, patients experience a sudden and severe worsening of their symptoms, known as an acute exacerbation (AE-IPF), which carries a high risk of mortality. Currently, doctors lack reliable bedside tools at the time of hospital admission to predict which patients will improve with standard care and which will require early escalation of treatment. This prospective observational study aims to determine if simple, widely available blood tests can be used as biomarkers to predict patient outcomes during an acute exacerbation. Researchers will focus on complete blood count (CBC)-derived inflammatory indexes, which are calculated ratios of different types of blood cells (such as the neutrophil-to-lymphocyte ratio). Participants hospitalized with AE-IPF will have their blood cell counts and oxygen levels (PaO2/FiO2 ratio) monitored on days 0 (admission), 3, 7, and 14. The study will evaluate the correlation between the change in these inflammatory indexes and the change in oxygen levels over the first week of hospitalization. Additionally, it will assess how accurately the admission blood test values, compared to the changes seen by day 3, can predict in-hospital clinical deterioration (such as the need for a ventilator, transfer to the intensive care unit, or death). The aim is to find out if tracking changes in these simple blood test indexes can provide clinicians with a cost-effective, early-warning tool to guide treatment decisions for patients suffering from AE-IPF.

Intravenous Immunoglobulin for the Treatment of Acute Exacerbations of Idiopathic Pulmonary Fibrosis

Acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF) are sudden and severe worsening episodes that can be life-threatening. Currently, no treatment has been proven to clearly improve outcomes during these events. Inflammation and immune system imbalance are thought to play an important role in causing AE-IPF. Early clinical experience suggests that intravenous immunoglobulin (IVIG) can be beneficial for patients suffering from AE-IPF. This clinical trial aims to determine whether adding IVIG to usual treatment can improve outcomes for patients hospitalized with AE-IPF.

Glucocorticoids Versus Placebo for the Treatment of Acute Exacerbation of Idiopathic Pulmonary Fibrosis

Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is associated with a poor prognosis, with a 3-month mortality rate of over 50%. To date, no treatment has been proven to be effective in AI-FPI. The interest of glucocorticoids is controversial and needs to be confirmed. This confirmation is mandatory to validate the improvement of the prognosis of EA-IPF under this treatment but also to search for unsuspected deleterious effects as it has been shown with immunosuppressants in stable idiopathic pulmonary fibrosis.
