Idiopathic pulmonary fibrosis in East Asian.

Idiopathic pulmonary fibrosis (IPF) is a rare lung disease with a prognosis that can be worse than that of many cancers. Recent studies have improved our understanding of IPF and new treatment options have become available. However, most studies are conducted predominantly in Western countries while few are conducted in East Asian countries. The distribution, effectiveness of treatment, and prognosis for IPF differ among Westerners and East Asians, but whether the heterogeneity of IPF in East Asians is the result of ethnic differences and geographic variability is unclear. This study highlights the current prevalence of IPF and its characteristics in the East Asian population and it provides valuable information to understand the current clinical status of patients with IPF in light of recent advances in its diagnosis and treatment.
