From the Guidelines

Covid-induced eosinophilic pneumonia should be treated with corticosteroids, such as prednisone 40-60mg daily, as the first-line therapy, based on the most recent evidence from 2024 1. The treatment approach for Covid-induced eosinophilic pneumonia involves immunomodulation to reduce inflammation and suppress the abnormal immune response to SARS-CoV-2 infection.

  • The use of glucocorticoids, such as prednisone, has been shown to be effective in reducing inflammation and improving outcomes in patients with Covid-19 pneumonia 1.
  • The dosage of prednisone typically ranges from 40-60mg daily, and the treatment duration is usually 2-4 weeks before gradually tapering over 2-3 months.
  • In severe cases requiring hospitalization, methylprednisolone 60-125mg IV every 6 hours may be initiated, transitioning to oral steroids as the patient improves.
  • Supportive care, including oxygen therapy and treatment of secondary bacterial infections with appropriate antibiotics, is also essential in managing Covid-induced eosinophilic pneumonia.
  • Close monitoring for clinical improvement and follow-up chest imaging after 2-4 weeks of treatment are crucial to assess the response to therapy and identify potential complications or alternative diagnoses.

From the Research

Covid Induced Eosinophilia Pneumonia

  • Covid-19 has been associated with various pulmonary complications, including eosinophilia pneumonia 2.
  • Eosinophilia is characterized by an increased count of eosinophils in the blood or tissue, and it has been observed in some patients with Covid-19 3.
  • Studies have shown that patients with eosinophilia tend to have a milder clinical course and better disease outcomes compared to those without eosinophilia 4, 3.
  • The use of inhaled corticosteroids (ICS) has been associated with improved outcomes in Covid-19 patients with eosinophilia 4.
  • Eosinophils have been shown to have antiviral properties, and their levels may vary dramatically in different clinical settings, including Covid-19 infections 2.

Treatment and Management

  • Remdesivir and corticosteroids are commonly used in the treatment of hospitalized Covid-19 patients 5, 6.
  • The effectiveness of remdesivir with and without corticosteroids has been assessed in several studies, with varying results 6.
  • The use of corticosteroids as adjunctive therapy to remdesivir has not been associated with improvement in mortality of Covid-19 patients 6.
  • Further studies are needed to determine the role of ICS and its interaction with eosinophilia in Covid-19 therapy 4.

Clinical Outcomes

  • Patients with eosinophilia tend to have lower levels of C-reactive protein (CRP) and milder clinical course compared to those without eosinophilia 3.
  • Eosinophilia has been correlated negatively with the duration of ICU admission, mechanical ventilation, and oxygen supplementation, as well as with CRP level 3.
  • The protective role of eosinophils in mitigating the severity of inflammatory diseases needs to be validated by further prospective studies 3.
