OBJECTIVES To evaluate changes in respiratory function in patients with ALS after using high-frequency chest wall oscillation (HFCWO). METHODS This was a 12-week randomized, controlled trial of HFCWO in patients with probable or definite ALS, an Amyotrophic Lateral Sclerosis Functional Rating Scale respiratory subscale score < or = 11 and > or = 5, and(More)
Non-invasive positive pressure ventilation (NPPV) can improve survival in ALS patients with advanced respiratory impairment, but it is not known if it is beneficial earlier in the disease course. A retrospective cohort study of patients with ALS was performed comparing survival from time of diagnosis in subjects who started NPPV use when their FVC was(More)
The rapidity of progression of amyotrophic lateral sclerosis (ALS) to death or respiratory failure impacts patients, clinicians, and clinical investigators. This study compared the abilities of various pulmonary function tests to predict tracheostomy-free survival. We evaluated 95 ALS patients by determining upright and supine forced vital capacity (FVC),(More)
INTRODUCTION Noninvasive positive pressure ventilation (NIPPV) is associated with improved survival in amyotrophic lateral sclerosis (ALS) and has been widely recommended. The extent of NIPPV use in ALS patients and the factors associated with its use have not been studied. METHODS A cross-sectional study using the ALS Patient Care Database. Analyses were(More)
RATIONALE Arikace is a liposomal amikacin preparation for aerosol delivery with potent Pseudomonas aeruginosa killing and prolonged lung deposition. OBJECTIVES To examine the safety and efficacy of 28 days of once-daily Arikace in cystic fibrosis (CF) patients chronically infected with P aeruginosa. METHODS 105 subjects were evaluated in double-blind,(More)
Patients with amyotrophic lateral sclerosis (ALS) invariably develop respiratory muscle weakness and most die from pulmonary complications. There are numerous tests available to evaluate respiratory status in ALS and it is important to understand their various advantages and limitations. Forced vital capacity (FVC) is commonly used but can remain normal(More)
INTRODUCTION Lung involvement is a common extra-articular manifestation of rheumatoid arthritis (RA) that confers significant morbidity and mortality. The objective of the present study is to assess which respiratory symptoms and patient and disease characteristics are most highly associated with pulmonary function test (PFT) abnormalities in an RA patient(More)
OBJECTIVE As ALS progresses, extensive supportive care is required, including multidisciplinary outpatient care and hospitalization. The authors studied the causes, health care utilization, and outcomes for hospitalized patients with ALS. METHODS With use of the 1996 Nationwide Inpatient Sample, an administrative database representing 20% of U.S.(More)
Respiratory complications are a common cause of morbidity and mortality in amyotrophic lateral sclerosis (ALS). Treatment of respiratory insufficiency with noninvasive ventilation (NIV) improves ALS patients' quality of life and survival. Evidence-based practice guidelines for the management of ALS patients recommend treatment of respiratory insufficiency(More)
