چکیده

Total plasma lactate dehydrogenase (LDH) activity may be elevated in cryptogenic fibrosing alveolitis (CFA) and extrinsic allergic alveolitis (EAA), and may be a useful monitor of disease progress. In a retrospective, primary referral centre study, we compared LDH at presentation, prior to bronchoalveolar lavage BAL, and after treatment and follow-up with changes in pulmonary function, in patients with CFA, EAA and pulmonary sarcoidosis. Plasma levels of LDH at presentation in CFA (n = 47) and EAA (n = 10) were significantly higher than in patients with sarcoidosis (n = 36). LDH activity decreased in patients with improving lung function (EAA, p = 0.008; CFA, p = 0.02), whereas it increased in CFA patients with deteriorating lung function (p = 0.015). Total plasma LDH is a simple, though nonspecific test, which appears to reflect changes of disease activity in patients with CFA and EAA.

Extrinsic allergic alveolitis: a disease commoner in non-smokers.

The smoking habits of 18 patients with extrinsic allergic alveolitis, 22 with cryptogenic fibrosing alveolitis, and 75 patients with sarcoidosis were compared with the smoking habits of the normal population of the Prairie Region for 1973. The patients were diagnosed at the same two hospitals over the four-year period November 1971--75 and were of comparable age. Non-smoking was significantly a...

Circulating antibodies to lung protein(s) in patients with cryptogenic fibrosing alveolitis.

BACKGROUND It has been hypothesised that cryptogenic fibrosing alveolitis has an immunological pathogenesis mediated by T lymphocytes. It is, however, recognised that patients may show dysregulation of the humoral immune system and that the presence of large numbers of B lymphocytes in open lung biopsies may be associated with a poor prognosis. Evidence of a role for the humoral immune system i...

Treatment of small cell lung carcinoma in association with cryptogenic fibrosing alveolitis.

Two patients with small cell bronchogenic carcinoma associated with cryptogenic fibrosing alveolitis are described. Both patients received radiotherapy and i.v. chemotherapy with moderate dose methotrexate (100 mg/M2) and escalating high dose cyclophosphamide (1-5 g, 2 5 g, 3-5 g/m2). Good symptomatic improvement was obtained with concurrent tumour response. No effect upon the alveolitis was ob...

BACKGROUND The aim of this study was to compare the distribution and configuration of lung opacities in patients with cryptogenic fibrosing alveolitis and asbestosis by high resolution computed tomography. METHODS Eighteen patients with cryptogenic fibrosing alveolitis and 24 with asbestosis were studied. Two independent observers assessed the type and distributions of opacities in the upper,...
