Nailfold videocapillaroscopy can increase diagnostic accuracy of ILD
When used in a multidisciplinary setting, nailfold videocapillaroscopy (NVC) can increase the diagnostic accuracy of interstitial lung diseases (ILD), especially in connective tissue disease-related ILD (CTD-ILD), followed by interstitial pneumonia with autoimmune features (IPAF) and idiopathic pulmonary fibrosis (IPF), according to a study.
Researchers analyzed 21 studies that report the occurrence of nailfold abnormalities (NVC+) in CTD-ILD, IPAF, and IPF cohorts. Prevalence of NVC+ was highest in CTD-ILD (80.4%), followed by IPAF (27.4%), and IPF (13.8%). Quality of evidence was low for these cohorts. In the CTD-ILD cohort, the most prevalent nailfold pattern was a Late Scleroderma pattern accounting for 40.4%. Quality of evidence was moderate in this cohort.
