RESUMO
Patients with cystic fibrosis (CF) experience repeated infectious respiratory exacerbations leading to a continuous decline in lung function. The exacerbations are treated in hospital or at home. Our aim was to compare the clinical outcome for patients undergoing intravenous antibiotic treatment either in hospital or at home. A retrospective 10-year study was performed in four regional CF Centers. The outcome measures were percentage changes in forced expiratory volume in 1 sec (FEV(1)), forced vital capacity (FVC) and weight for age z-score (WZS). FEV(1), FVC, and WZS changes were calculated for the entire study period and for each course. A total of 1,164 courses were analyzed. For each course, the mean improvement in FEV(1) and FVC was significantly higher when performed in hospital than when performed at home (P < 0.05). FEV(1) and FVC values were 10.2%, 9.5% respectively in the hospital group and 7.3%, 6.8% in the home group. A total of 153 patients were analyzed (51 inpatients matched to 102 patients treated at home). The two groups had no significant differences in any outcome variable at baseline. The mean variation per year in FEV(1) was greater in the hospital group versus the home group (-0.4% vs. -1.8%; P = 0.03). The mean variation per year in WZS was greater in the hospital group versus the home group (P < 0.01). Clinical outcome, as defined by spirometric parameters and body weight, was better after a course of treatment in hospital than after a home treatment. This benefit was maintained throughout of the study period.

To define the clinical characteristics, prognosis and treatment of myocardial infarction (MI) in the elderly, we retrospectively compared the files of 101 patients aged > or = 75 years (mean: 82 +/- 4 years) and of 120 others aged < or = 65 years (mean: 55 +/- 4.7 years). The figures corresponding to younger patients are presented in brackets. The elderly group included 60.4% women (5%: p < 0.001), 58.9% hypertensive subjects (38.3%: p = 0.005); 30.4% diabetics (11.7%: p = 0.0013) and 12.6% smokers (66.1%: p < 0.001); 20.8% of the elderly had a history of MI (10%: p = 0.002), 15.8% of arteriopathy of the lower limbs (8.3%: p = 0.001) and 6.9% of cerebrovascular accident (1.7%: p = 0.02). Elderly patients were admitted after an average of 26.6 hours (10.4 hours: p < 0.001). Only 56.4% (79.2%) reported typical MI pain, 22.8% (7.5%) had a painless form, 31.8% (4.2%) an initial left ventricular failure, 21.8% (7.5%) a global cardiac dysfunction and 20.8% (4.2%) a cardiogenic shock (p < 0.001 for all comparisons). 63.4% had an anterior MI (40.8%: p < 0.001), 40.6% a Q-form (29.6%: p = NS) and 22.2% an atrial fibrillation (0.8%: p < 0.001). Serum myoglobin and total CK concentrations were significantly lower in elderly subjects. 20.8% of them received beta-blockers (86.7%), 43.6% aspirin (80%), 14.6% oral anticoagulant (56.7%), but 63.4% were given diuretics (25.2%) and 31.7% digitalis alkaloids and positive inotropic drugs (6.7%) (p < 0.001 for all these comparisons). Heparin, nitrates, calcium channel blockers, ACE inhibitors and antiarrhythmics were prescribed as often regardless of age. Only 10 elderly patients (9.9%) were treated with thrombolytics (77: 65%: p < 0.001); 6 (5.9%) underwent coronary angiography (43: 35.8%: p < 0.001), 2 (2%) angioplasty (11: 9.2%) and one (1%) coronary bypass surgery (12: 10%). 35 elderly patients (34.7%) died while in hospital (5: 4.2%), 22 suddenly, 10 in cardiogenic shock and 3 due to arrhythmias. 38 cases (37.8%) of heart failure (21: 17.5%), 21 (20.8%) recurrences of coronary insufficiency (8: 6.7%) and 11 (10.9%) mechanical complications of MI (4: 3.3%) were also observed (p < 0.001 for all these comparisons). Due to lack of sufficient data, we could not define the status of the surviving patients discharged from hospital. The wider use of thrombolytics, angiography and angioplasty (coronary bypass surgery still having a heavy mortality and morbidity) is probably the best way to improve the prognosis of MI in the elderly.
