This thesis reviews the current literature on idiopathic pulmonary fibrosis (IPF), a progressive, scarring lung condition largely affecting older adults that is experiencing an increasing incidence in the U.S. and abroad. Two troubling clinical aspects of IPF are the difficulty of timely diagnosis and uncertain progression once diagnosed. The need for early detection is driven by the condition’s median survival rate post-diagnosis of about 3 years. Environmental and familial risk factors are important predictors of IPF, but cannot alone determine who is at risk for the condition. High-resolution computed tomography is currently the best non-invasive diagnostic tool, but many efforts are now underway to identify biological markers, which may aid not only in diagnosis, but illuminate both susceptibility and progression of the disease. Although the pathogenesis of IPF remains unclear, a compelling correlation has surfaced between the mechanics of IPF and herpes virus infection, which also may lead to a biological marker for the condition. Likewise, some genetic factors have shown promise in revealing pathogenesis and possible diagnosis. The only treatment currently available to ameliorate IPF is lung transplantation, but it is a last resort effort. In terms of pharmaceutical treatment, the most significant development has been the recent approval and use of two anti-fibrotic drugs, pirfenidone and nintedanib, that appear to slow the progression of the disease, but do not eliminate the fibrotic condition that impairs patients’ breathing. As efforts progress in addressing affirmative treatments for IPF, there is consensus that not enough is being done to address palliative and psychological needs of IPF. In sum, a review of the current literature suggests tremendous accomplishments have made in treating what remains a fatal condition, but much work remains to truly understand how and why IPF occurs, and whether, short of lung transplantation, there are treatments that can improve, not just maintain, patients’ health.
