    ABSTRACT: The frequency of metabolic alkalosis among adults with stable severe CF-lung disease is unknown. Retrospective chart review. Fourteen CF and 6 COPD (controls) patients were included. FEV1 was similar between the two groups. PaO2 was significantly higher in the COPD (mean ± 2 SD is 72.0 ± 6.8 mmHg,) than in the CF group (56.1 ± 4.1 mmHg). The frequency of metabolic alkalosis in CF patients (12/14, 86%) was significantly greater (p=0.04) than in the COPD group (2/6, 33%). Mixed respiratory acidosis and metabolic alkalosis was evident in 4 CF and 1 COPD patients. Primary metabolic alkalosis was observed in 8 CF and none of the COPD patients. One COPD patient had respiratory and metabolic alkalosis. Metabolic alkalosis is more frequent in stable patients with CF lung disease than in COPD patients. This might be due to defective CFTR function with abnormal electrolyte transport within the kidney and/ or gastrointestinal tract.

    ABSTRACT: To develop an Arabic version of the Chronic Respiratory Disease Questionnaire (CRQ) to be known as ArabiCRQ. We conducted a linguistic validation of the CRQ in the Arabic language. The validation process involved 4 phases, including forward and backward translations, pilot testing, and revision to produce a final version of the ArabiCRQ. Five native Arabic-speaking patients with chronic obstructive pulmonary disease completed the ArabiCRQ both in initial and follow-up visits. Wording was modified according to feedback the participants provided. Two of the patients' scores changed appreciably, despite ensuring their clinical stability. The ArabiCRQ may be a valuable tool to assess the health-related quality of life in patients with chronic respiratory diseases.

    ABSTRACT: Some patients with chronic obstructive pulmonary disease (COPD) may benefit from oral steroid therapy. These steroid-responsive patients are diagnosed based on laboratory spirometry. We hypothesize that daily, home-based spirometry is a better tool. Thirty patients with COPD underwent a single-blinded study, with a crossover design. They received 2 weeks of placebo followed by 2 weeks of prednisone therapy (40 mg/day). Laboratory spirometry was done at the beginning and end of the study and daily home-based spirometry was done twice a day. Analysis of variance model was used. The variability of the median day-to-day forced expiratory volume in 1 s (FEV₁) was 72.5 mL (25th percentile of 40 mL and 75th percentile of 130 mL). The daily FEV₁ variation was 70 mL (25th percentile of 50 mL and 75th percentile of 100 mL). The overall laboratory FEV₁ variability was larger after the steroid course (P < 0.001), but not clinically significant. The variability was not significant postplacebo treatment compared with the baseline values. For home-based spirometry, steroid treatment was not significantly different. The majority (97%) completed more than 80% of the measurements. Ninety percent of the performed tests were considered acceptable. Only 53% of the tests were considered accurate. Overall both laboratory and home-based measurements did not show significant association between airway responsiveness and dyspnea or exercise capacity. Twice-daily home measurements of FEV₁ might be better than the conventional approach to identify steroid responsive COPD patients. However, this finding was only statistically but not clinically significant. Therefore, we would not recommend this approach to identify COPD patients with steroid responsiveness.

    ABSTRACT: Creatine improves muscle strength in exercising healthy individuals, and in patients with neuromuscular disease and heart failure. The aim of this study was to assess whether creatine supplementation improves pulmonary rehabilitation (PR) outcomes in patients with COPD. A systematic review and meta-analysis was performed of randomized controlled trials published between January 1966 and February 2009 that evaluated the effect of creatine compared with placebo on exercise capacity, muscle strength and health-related quality of life (HR-QoL) in patients undergoing PR for COPD. The pooled estimates were expressed as mean differences (MD) or standardized mean differences (SMD). Four randomized controlled trials that included 151 patients were identified. There was no effect of creatine supplementation on exercise capacity (SMD -0.01, 95% CI: -0.42 to 0.22, n = 151). Creatine supplementation did not improve lower extremity muscle strength (SMD 0.03, 95% CI: -0.55 to 0.61, n = 140) or upper limb muscular strength (SMD 0.02, 95% CI: -0.33 to 0.38, n = 128) compared with placebo. Two studies (n = 48) assessed quality of life using the St. George's Respiratory Disease Questionnaire. There were no differences in HR-QoL according to domain or total scores. Overall, creatine appeared to be safe and was well tolerated. Quality assessment of the studies showed important limitations. Creatine supplementation does not improve exercise capacity, muscle strength or HR-QoL in patients with COPD receiving PR. However, important limitations were identified in the quality of the available evidence, suggesting that further research is required in this area.
