Objective: To compare the efficacy, safety, and tolerability of azithromycin and amoxicillin in the treatment of patients with infectious exacerbation of chronic obstructive pulmonary disease. Methods: This study was conducted at six medical centers across Brazil and included 109 patients from 33 to 82 years of age. Of those, 102 were randomized to receive either azithromycin (500 mg/day for three days, n = 49) or amoxicillin (500 mg every eight hours for ten days, n = 53). The patients were evaluated at the study outset, on day ten, and at one month. Based on the clinical evaluation of the signs and symptoms present on day ten and at one month, the outcomes were classified as cure, improvement, or treatment failure. The microbiological evaluation was made through the culture of sputum samples that were considered appropriate samples only after leukocyte counts and Gram staining. Secondary efficacy evaluations were made in order to analyze symptoms (cough, dyspnea, and expectoration) and pulmonary function. Results: There were no differences between the groups treated with azithromycin or amoxicillin in terms of the percentages of cases in which the outcomes were classified as cure or improvement: 85% vs. 78% (p = 0.368) on day ten; and 83% vs. 78% (p = 0.571) at one month. Similarly, there were no significant differences between the two groups in the secondary efficacy variables or the incidence of adverse effects. Conclusion: Azithromycin and amoxicillin present similar efficacy and tolerability in the treatment of acute exacerbation of chronic obstructive pulmonary disease.

Objective: To characterize the presence, extent, and patterns of dynamic hyperinflation (DH) during treadmill exercise testing in patients with moderate to severe COPD. Methods: This was a cross-sectional study involving 30 non-hypoxemic patients (FEV1= 43 ± 14% of predicted) who were submitted to a cardiopulmonary exercise test on a treadmill at a constant speed (70-80% of maximum speed) to the tolerance limit (Tlim). Serial inspiratory capacity (IC) maneuvers were used in order to assess DH. Results: Of the 30 patients studied, 19 (63.3%) presented with DH (DH+ group), having greater pulmonary function impairment at rest than did those without DH (DH− group). None of the variables studied correlated with exercise tolerance in the DH− group, whereas Tlim, IC, and perception of dyspnea during exercise did so correlate in the DH+ group (p < 0.05). In the DH+ group, 7 and 12 patients, respectively, presented with a progressive and a stable pattern of DH (ΔICTlim,2min = −0.28 ± 0.11 L vs. 0.04 ± 0.10 L; p < 0.01). Patients with a progressive pattern of DH presented with higher perception of dyspnea/Tlim rate and lower exercise tolerance than did those with a stable pattern (354 ± 118 s and 465 ± 178 s, respectively; p < 0.05). Conclusions: The presence of DH is not a universal phenomenon during walking in COPD patients, even in those with moderate to severe airflow limitation. In the patients who presented DH, a progressive pattern of DH had a greater impact on exercise tolerance than did a stable pattern of DH.

Pleural effusion: an extraintestinal complication of Crohn's disease

Derrame pleural: uma complicação extra-intestinal da doença de Crohn

Elie Fiss, Flavio Steinwaurz, Andrea Barranjard Vannucci, Camila de Menezes Succi

J Bras Pneumol.2002;28(5):285-287

Abstract PDF PT

A 34-year-old patient had had Crohn's disease (CD) for eight years; she was seen for complaints of thoracic pain and fever, without gastrointestinal manifestations. Initial laboratory exams were compatible with the presence of inflammatory activity (VHS = 45 mm for normal value of 20 mm and PCR+). The physical exam revealed signs of pleural effusion in the left hemithorax base, which was confirmed by thoracic RX. The pleural liquid analysis showed that the cells were 100% of lymphocytes, with negative BAAR research. The pleural biopsy evidenced non caseous granuloma. Despite the tuberculosis treatment, the patient only got better when corticotherapy was introduced in high doses, suggesting the activity of CD as the cause of the pleural effusion. This case establishes a connection between activity of CD and manifestations of lung disease.

 



Bronchial hyperresponsiveness in patients with gastroesophageal reflux disease

Estudo da hiper-responsividade brônquica em pacientes portadores de refluxo gastroesofágico

J Bras Pneumol.2005;31(4):286-291

Abstract PDF PT PDF EN Portuguese Text

Objective: To identify this vagal reflex using bronchial provocation tests in patients with gastroesophageal reflux disease. Methods: The study group was composed of 10 patients presenting endoscopic evidence of hiatal hernia or gastroesophageal reflux disease, and the control group consisted of 11 patients presenting no evidence of either condition. All subjects were submitted to bronchial provocation with carbachol. Results: The provocation test was positive in 5 (50%) of the study group patients and 3 (27%) of the control group patients (p = 0.64). Conclusion: The hypothesis that the airways of patients with gastroesophageal reflux disease (and no history of asthma-like respiratory symptoms) might be more responsive than those of individuals without the disease remains unproven.

Can bronchodilators improve exercise tolerance in COPD patients without dynamic hyperinflation?

Os broncodilatadores podem melhorar a tolerância ao exercício na ausência de hiperinsuflação dinâmica em pacientes com DPOC?

Objective: To investigate the modulatory effects that dynamic hyperinflation (DH), defined as a reduction in inspiratory capacity (IC), has on exercise tolerance after bronchodilator in patients with COPD. Methods: An experimental, randomized study involving 30 COPD patients without severe hypoxemia. At baseline, the patients underwent clinical assessment, spirometry, and incremental cardiopulmonary exercise testing (CPET). On two subsequent visits, the patients were randomized to receive a combination of inhaled fenoterol/ipratropium or placebo. All patients then underwent spirometry and submaximal CPET at constant speed up to the limit of tolerance (Tlim). The patients who showed ΔIC(peak-rest) < 0 were considered to present with DH (DH+). Results: In this sample, 21 patients (70%) had DH. The DH+ patients had higher airflow obstruction and lower Tlim than did the patients without DH (DH−). Despite equivalent improvement in FEV1 after bronchodilator, the DH− group showed higher ΔIC(bronchodilator-placebo) at rest in relation to the DH+ group (p < 0.05). However, this was not found in relation to ΔIC at peak exercise between DH+ and DH− groups (0.19 ± 0.17 L vs. 0.17 ± 0.15 L, p > 0.05). In addition, both groups showed similar improvements in Tlim after bronchodilator (median [interquartile range]: 22% [3-60%] vs. 10% [3-53%]; p > 0.05). Conclusions: Improvement in TLim was associated with an increase in IC at rest after bronchodilator in HD− patients with COPD. However, even without that improvement, COPD patients can present with greater exercise tolerance after bronchodilator provided that they develop DH during exercise.

Smoking among physicians in a specific region of the greater metropolitan area of São Paulo

Tabagismo entre médicos da Região do ABC Paulista

Adriano Cesar Guazzelli, Mário Terra Filho, Elie Fiss

J Bras Pneumol.2005;31(6):516-522

Abstract PDF PT PDF EN Portuguese Text

Objective: To evaluate the prevalence of and describe the methods used to control the smoking habit among a geographically-specific population of physicians. Methods: Questionnaires were distributed to physicians practicing in a region of the greater metropolitan area of São Paulo area known as the "ABC Paulista" (comprising the municipalities of Santo Andre, São Bernardo and São Caetano), and completed questionnaires were received from 678 physicians, all registered with the São Paulo State Regional Council of Medicine. Results: Of the 678 responding physicians, 58 (8.6%) were smokers, 183 (27.0%) were former smokers, and 437 (64.5%) were nonsmokers. No gender-based differences were found. Nor were there any significant differences in prevalence based on medical specialty. Most of the smokers had tried to stop smoking. Among the smokers, cessation methods were used by 7%: nicotine replacement therapy by 4.3%; and acupuncture by 2.7%. Most of the former smokers (88.1%) had successfully quit smoking without using any cessation methods. Conclusion: The prevalence of smoking among physicians in the ABC Paulista region was 8.6%. In this region, the majority of physicians who quit smoking did so without the aid of smoking cessation methods. Among those who did use such methods, nicotine replacement therapy was the method of choice.
