Background and objective: In this study the prevalence, lung function and prognosis of IPF combined with emphysema were evaluated. Methods: Consecutive patients with usual interstitial pneumonia (UIP) on high‐resolution computed tomography (HRCT), with or without emphysema, were assessed retrospectively. The area of fibrosis in the base of the lungs was assessed by HRCT as minimal (<2 cm from the subpleura), moderate (≥2 cm from the subpleura, <1/3 of the area of the base of the lungs) or severe (≥1/3 of the area of the base of the lungs). Results: Among 660 patients with UIP on HRCT, 221 showed upper‐lobe emphysema. Pulmonary function results for patients with UIP and UIP/emphysema, respectively, were: FVC, 71.8% and 87.1%; FEV1%, 86.7% and 87.9%; and DLCO, 74.3% and 65.2% of predicted. The relationship between FVC, the extent of fibrosis and survival was investigated in 362 patients with records of pulmonary function tests and no lung cancer at the time of entry into the study. Although the extent of fibrosis was similar between the groups, 71.3% of UIP patients met the lung volume criteria for IPF (FVC <80% of predicted), whereas only 26.5% of UIP/emphysema patients met the lung volume criteria for IPF. Median survival was 7.5 years in the UIP group and 8.5 years in the UIP/emphysema group. Conclusions: Emphysema was a common finding in patients with UIP. Patients with UIP and emphysema had greater lung volumes and better survival compared with those with UIP alone. 相似文献

Background and objective: The effects of tiotropium, a long‐acting anticholinergic drug, were compared with those of the combination of salmeterol, a long‐acting β2‐agonist, and fluticasone, an inhaled corticosteroid, in patients with COPD. Methods: A 4‐month, randomized, open cross‐over study of tiotropium, 18 µg once daily, versus salmeterol, 50 µg, plus fluticasone, 200 µg, twice daily, was conducted in patients with COPD. Efficacy was assessed by spirometry and responses to the St George's Respiratory Questionnaire (SGRQ). After 4 months, patients were asked to select their subsequent therapy and indicate the reasons for their selection. Results: A total of 78 patients completed the study. There were no significant differences in the improvements in FEV1 or SGRQ scores between the therapies. Similar numbers of patients selected tiotropium (42.3%) and salmeterol plus fluticasone (57.7%). However, those who preferred one of the therapies demonstrated greater improvements in SGRQ scores with that therapy. One subgroup of patients (30.8%) showed greater improvements in dyspnoea and FEV1 in response to tiotropium, and the other subgroup of patients (35.9%) showed greater improvements in dyspnoea and FEV1 in response to salmeterol plus fluticasone. Some patients (14.1%) selected salmeterol plus fluticasone because of positive effects on sputum expectoration. Conclusions: The study was unblinded and the results need to be interpreted with caution. However, tiotropium and salmeterol plus fluticasone had similar overall effects on pulmonary function and SGRQ scores in patients with COPD. Responses to the two therapies were heterogeneous, and the patients who showed greater improvements in FEV1 or SGRQ scores with one of the therapies preferred it for their subsequent treatment. 相似文献

Summary: We investigated the influence of glycaemic control and hypertension on the progression of renal structural changes in 18 patients with non-insulin dependent diabetes mellitus (NIDDM) who had undergone sequential renal biopsies. Renal biopsies were performed after median interval of 6.0 years (range 2-11 years). the severity of glomerular diffuse lesions was graded on a 5-point scale according to Gellman's criteria. Subjects were divided into two groups: (i) patients who showed progression of glomerular diffuse lesions ( n = 12); and (ii) patients who showed no change in histological grade ( n = 6). Mean arterial blood pressure was significantly higher in group 1. There was no significant difference in the HbA1c between the two groups. These findings suggest that the mean arterial blood pressure is closely related to the progression of glomerular morphological changes regardless of the status of glycaemic control. 相似文献

Background and objective: In some patients, desquamative interstitial pneumonia may progress to lung fibrosis. The aim of this study was to assess the long‐term radiological follow‐up results in patients with desquamative interstitial pneumonia. Methods: Among 75 patients suspected of having desquamative interstitial pneumonia, 31 who fulfilled the criteria were included in this study. Clinical characteristics at presentation, responses to treatment and long‐term follow‐up were evaluated. Results: The 31 patients were predominantly males (94%), and the mean age was 55 years; 93% (28/30) had a history of smoking. The clinical findings included high serum levels of lactate dehydrogenase and immunoglobulin G. Bronchoalveolar lavage (26 patients, 84% of cases) frequently showed an increased percentage of eosinophils (mean 17%). Computed tomography (CT) or high resolution (HR) CT at presentation showed ground glass opacities and/or consolidation in all patients, with one third of patients also showing thin‐walled cysts within the ground glass opacities. There was no honeycombing on CT or HRCT scans at presentation. Corticosteroid therapy was effective early in the course of the disease; long‐term follow‐up (mean 99 months) of 31 patients showed only one death due to progression of the disease, but long‐term follow‐up of 14 patients (mean 125 months) by HRCT showed the development of new thin‐walled cysts and honeycombing in five and lung cancer in four patients, respectively. Conclusions: In a proportion of patients, desquamative interstitial pneumonia may progress to lung fibrosis with honeycombing on HRCT, despite therapy. 相似文献

Summary Seven out of nine patients (78%). seen over a 13-year period with hypergammaglobulinaemic purpura of Waldenström were found to have antibodies to Ro/SSA. Over this period we saw 175 patients who had antibodies to Ro/SSA. In six of the seven patients. associated diseases were recognized. Five had Sjögren's syndrome, and one had systemic lupus erythematosus with Sjögren's syndrome and thyroiditis (and died 19 years after initial presentation from cerebral infarction). Screening for antibodies to Ro/SSA is important in the diagnosis of patients with hypergammaglobulinaemic purpura. and is helpful in predicting prognosis. 相似文献
