Monitoring and management of ILD progression in CTD-ILDs

Regular monitoring for progression of connective tissue disease-associated interstitial lung diseases (CTD-ILDs) is vital to inform appropriate care1

Julie

EARLY AND REGULAR MONITORING OF PULMONARY FIBROSIS IN PATIENTS IS IMPORTANT TO DETECT THE PROGRESSIVE FIBROSING PHENOTYPE1,2

Up to 4 in 10 patients with CTD-ILDs can develop a progressive fibrosing phenotype.3–7

The progressive fibrosing phenotype is defined by the presence of:2,8-10

There is currently no uniformly endorsed definition of the progressive fibrosing phenotype,11 and, in clinical practice, no threshold or rate of decline has been formally accepted12

Once alternative explanations, such as respiratory tract infection, have been excluded and treated, patients with ILDs meeting the following criteria at any point within 24 months despite treatment in clinical practice can be considered to have progressive fibrosis:13

  • Relative decline of ≥10% in FVC 

  • Relative decline of ≥5–<10% in FVC and relative decline of ≥15% in DLCO

  • Relative decline of ≥5–<10% in FVC and worsening of respiratory symptoms

  • Relative decline of ≥5–<10% in FVC and increased extent of fibrosis on HRCT

  • Worsening of respiratory symptoms and increased extent of fibrosis on HRCT

TIME IS OF THE ESSENCE WHEN PROGRESSIVE FIBROSING ILD IS SUSPECTED9

Delayed detection of progressive pulmonary fibrosis in ILDs can be deadly. Patients have an estimated survival time of 2.5–4 years after detection of progressive fibrosis4,9* Early detection of patients with progressive fibrosing ILD could inform management decisions and patient counselling4

HOW COULD THE TIME BETWEEN ILD DIAGNOSIS AND DETECTION OF THE PROGRESSIVE FIBROSING PHENOTYPE IN YOUR PATIENTS BE SHORTENED?

A patient with CTD-ILD could wait an average of 2.5–3 years from initial ILD symptoms to the diagnosis of progressive fibrosing ILD4*

IN CTD-ILDs, ILD MONITORING CAN BE OPTIMIZED BY CROSS-SPECIALTY COLLABORATION1

Multidisciplinary evaluation is the gold standard in the diagnosis of ILD and evaluation of its severity14

In instances when an MDT is challenging to convene for a patient with ILD, multidisciplinary discussion can be conducted virtually or by telephone to enable each specialty group to contribute15

PFTs at regular 3–4-month intervals† can help identify progression of CTD-ILDs1

Measurements taken during PFTs should include FVC, DLCO and TLC1

Despite its limitations in identifying ILD in patients with CTD, the 6MWD can be used to monitor ILD progression and provide prognostic information for established CTD-ILD – therefore, a regular assessment of the 6MWD is suggested1

Awareness of patient language can help identify the symptoms of ILD in CTDs16

ssc

All patients with SSc-ILD need to be followed up every 3–6 months with PFTs, and repeated HRCT as guided by clinical decision, given the highly variable progression of the disease17,18

ra

Monitoring for RA-ILD progression with PFTs is recommended at 3–6-monthly intervals, then every 6–12 months if stable19

Monitoring for progression of primary Sjögren's syndrome-ILD using PFTs is recommended every 3–6 months in the first 1–2 years20

TREATMENT OF PROGRESSIVE CTD-ILD SHOULD NOT WAIT1,14

A multidisciplinary discussion should be initiated upon diagnosis of ILD in patients with CTD, and during their monitoring, to determine the optimal approach to slow ILD progression12,13

The decision to treat CTD-ILD can be based on whether the patient is clinically impaired by the ILD, whether the ILD is progressive by symptoms, physiology and/or imaging, and what extrathoracic features require therapy1
