Comparison of a beta-lactam alone versus beta-lactam and an aminoglycoside for pulmonary exacerbation in cystic fibrosis.

Unlabelled: We determined whether a beta-lactam and an aminoglycoside have efficacy greater than a beta-lactam alone in the management of a pulmonary exacerbation in patients with cystic fibrosis.

Study Design: Azlocillin and placebo or azlocillin and tobramycin were administered to 76 patients with a pulmonary exacerbation caused by Pseudomonas aeruginosa in a randomized double-blind, third-party monitored protocol. Improvement was assessed by standardized clinical evaluation, pulmonary function testing, sputum bacterial density, sputum DNA content, and time to the next pulmonary exacerbation requiring hospitalization.

Timing of referral for lung transplantation for cystic fibrosis: overemphasis on FEV1 may adversely affect overall survival.

Study Objectives: (1) Report our experience with referral for lung transplantation. (2) Review survival in cvstic fibrosis (CF) patients without lung transplantation after FEV1 remains < 30% predicted for 1 years.

Design: Retrospective review.

Stenotrophomonas maltophilia in cystic fibrosis: incidence and prevalence.

Stenotrophomonas maltophilia (SM) was recovered from 211 of 773 cystic fibrosis (CF) patients followed for at least one year, and seen between 1982 and 1994. Yearly prevalence (5.6% to 8.

Sodium space and intravascular volume: dietary sodium effects in cystic fibrosis and healthy adolescent subjects.

Objective: To assess the physiologic response to salt depletion in subjects with cystic fibrosis (CF) and control male adolescents for sodium balance, sodium space, and stimulation of the renin-angiotensin-aldosterone axis.

Design: Seven subjects with CF and six controls received a salt-replete (150 or 290 mmol NaCl per day) diet and then a salt-deplete (10 mmol NaCl per day) diet while in a clinical research center.

Results: Space maintenance: CF subjects responded to salt depletion with a greater weight loss than did controls (1.

Pulmonary intralobar sequestration in a patient with cystic fibrosis.

We report a case in which pulmonary Intralobar Sequestration (ILS) was an incidental finding at autopsy in an adult with Cystic Fibrosis. Two aberrant arteries from the descending thoracic aorta supplied a bronchial cystic lesion in the right lower lobe. Termination of the segmental bronchus and scar formation proximal to the cyst suggested prior bronchial obliteration.
