RATIONALE High-resolution computed tomography (HRCT) is an integral aspect of the evaluation of patients with suspected idiopathic pulmonary fibrosis (IPF). However, few studies have evaluated its use in a large cohort. OBJECTIVES To describe HRCT features in patients with mild to moderate IPF, compare diagnostic evaluations by a radiology core (three(More)
BACKGROUND Prospective data defining the clinical course in idiopathic pulmonary fibrosis (IPF) are sparse. OBJECTIVE To analyze the clinical course of patients with mild to moderate IPF. DESIGN Analysis of data from the placebo group of a randomized, controlled trial evaluating interferon-gamma1b. SETTING Academic and community medical centers. (More)
BACKGROUND Idiopathic pulmonary fibrosis is a progressive, fatal disease with no known efficacious therapy. METHODS In a double-blind, multinational trial, we randomly assigned 330 patients with idiopathic pulmonary fibrosis that was unresponsive to corticosteroid therapy to receive subcutaneous interferon gamma-1b or placebo. RESULTS Over a median of(More)
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a devastating disease, yet validated, reliable criteria for evaluating patient response to therapies in clinical trials are lacking. METHODS To optimize selection of end point criteria for the study of interferon (IFN)-gamma1b in patients with IPF, we retrospectively analyzed the components of the primary(More)
In chronic granulomatous disease (CGD), diminished or absent neutrophil NADPH oxidase function leads to recurrent pyogenic infections and granuloma formation. In a recent randomized, placebo-controlled trail, short-term prophylactic use of recombinant human interferon gamma (rIFN-gamma 1b) reduced the risk of serious infection in CGD patients by 67%, The(More)
In a recent study of IFN-gamma 1b in 330 patients with idiopathic pulmonary fibrosis (IPF), progression-free survival was unchanged; however, a trend toward lower mortality was seen in IFN-gamma 1b-treated patients compared with placebo-treated patients (9.9 vs. 16.7%; p = 0.08). The purpose of this randomized, double-blind, placebo-controlled trial was to(More)
We conducted a 2-year prospective study of diarrheal illness in children ages 0 to 36 months in 22 day care centers in Maricopa County, Arizona. In 7464 child-months of observation, 465 sporadic cases and 170 outbreak-associated cases of diarrhea were identified. Enteric pathogens were identified in 20% of diarrhea episodes. Giardia lamblia, rotavirus, and(More)
During an outbreak of influenza A, seven patients with Reye's syndrome and 16 ill classmate control subjects were evaluated for characteristics of the patients' prodromal illness and the control subjects illness and for medication usage. Patients during the prodrome and control subjects had similar rates of sore throat, coryza, cough, headache, and(More)
Antibiotic usage was assessed in a prospective, randomized trial of recombinant interferon-gamma (rIFN-gamma) versus placebo for 212 severely injured trauma patients in four university hospitals. All patients were observed until death or discharge from the hospital. We found the number of antibiotics used and their associated costs staggering and difficult(More)
Over a 21-month interval, we investigated the effectiveness of immunoglobulin (lg) in preventing hepatitis A spread in day-care centers. Immunoglobulin was given to all center and employees whenever hepatitis occurred in one center child or employee or parents in two families. Immunoglobulin programs were completed in 91 centers during the trial within an(More)
