Understanding the impact of COVID-19 on lung health

The UK Interstitial Lung Disease Long-COVID19 Study (UKILD-Long COVID): Understanding the Burden of Interstitial Lung Disease in Long COVID.

Imperial College London · NCT05514522

This study is testing how COVID-19 affects lung health in people with ongoing breathing problems to better understand their condition and improve future treatments.

What this trial studies

This observational study aims to recruit 2000 individuals who have experienced COVID-19 and are experiencing persistent respiratory symptoms. Participants will undergo cross-sectional imaging to assess the extent of interstitial lung disease (PC-ILD) and its natural history. The study will explore risk factors, biomarkers, and the long-term implications of SARS-CoV-2 infection, with the goal of informing treatment strategies and clinical trial stratification. It will run for 18 months and is managed by the Imperial College National Heart and Lung Institute.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 who have had confirmed SARS-CoV-2 infection and are experiencing persistent respiratory symptoms.

Not a fit: Patients with significant pre-existing lung disease or life-limiting illnesses may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of lung complications following COVID-19.

How similar studies have performed: Other studies have shown success in understanding post-COVID conditions, but this specific focus on PC-ILD is relatively novel.

Eligibility criteria

Inclusion Criteria:

1. Age \>18 years old -99 years old
2. Evidence of SARS-CoV-2 infection confirmed by PCR or serology 3 months (+/- 6 weeks) earlier
3. Clinical indication for a chest CT scan as per clinician judgment

Exclusion Criteria:

1. Life-limiting illness within 12 months
2. Significant pre-existing lung disease prior to March 2020, which in the investigator's judgement could make the chest CT scans difficult to interpret
