BACKGROUND Although the etiology of idiopathic pulmonary fibrosis (IPF) remains perplexing, adaptive immune activation is evident among many afflicted patients. Repeated cycles of antigen-induced proliferation cause T-cells to lose surface expression of CD28, and we hypothesized this process might also occur in IPF. METHODOLOGY/PRINCIPAL FINDINGS(More)
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a progressive and medically refractory lung disease with a grim prognosis. Although the etiology of IPF remains perplexing, abnormal adaptive immune responses are evident in many afflicted patients. We hypothesized that perturbations of human leukocyte antigen (HLA) allele frequencies, which are often seen(More)
We hypothesized B cells are involved in the pathogenesis of idiopathic pulmonary fibrosis (IPF), a progressive, restrictive lung disease that is refractory to glucocorticoids and other nonspecific therapies, and almost invariably lethal. Accordingly, we sought to identify clinically associated B cell-related abnormalities in these patients. Phenotypes of(More)
BACKGROUND Severe acute exacerbations (AE) of idiopathic pulmonary fibrosis (IPF) are medically untreatable and often fatal within days. Recent evidence suggests autoantibodies may be involved in IPF progression. Autoantibody-mediated lung diseases are typically refractory to glucocorticoids and nonspecific medications, but frequently respond to focused(More)
In the penultimate sentence of the Results section of the Abstract, the plus sign should be a plus-or-minus sign. The correct sentence is: One-year survival of trial subjects was 46±15% vs. 0% among historical controls. In Table 2, spaces are missing before the acronym " PEEP " in the " Pre-Rx O 2 " and " Post-Rx O 2 " columns. Please see the correct Table(More)
RATIONALE Emphysema and osteoporosis are epidemiologically associated diseases of cigarette smokers. The causal mechanism(s) linking these illnesses is unknown. We hypothesized autoimmune responses may be involved in both disorders. OBJECTIVES To discover an antigen-specific autoimmune response associated with both emphysema and osteoporosis among(More)
