Alpha-1-protease inhibitor in bronchial asthma: phenotypes and biochemical characteristics.

The prevalence of the different phenotypes of alpha 1-protease inhibitor (alpha 1PI) was investigated in a group of 90 asthmatic patients and compared with that of a control group of 240 individuals representing the general population. The M2M2 phenotype occurred more frequently in the asthmatic group (p = 0.015). Plasma samples of 51 of the asthmatic patients randomly selected from the different phenotype groups identified were studied for the absolute plasma values of alpha 1-PI and the inhibitory capacity of plasma for porcine pancreatic elastase, and compared with those from 21 nonasthmatic individuals of the M1M1 phenotype. Although the asthmatic patients had higher absolute alpha 1PI values (p = 0.04), the plasma elastase inhibitory capacity was markedly reduced compared with the nonasthmatic subjects (p = 0.01). The functional efficiency of alpha 1PI from asthmatic patients of the M1M1, M1M2, and M2M2 phenotypes was significantly decreased compared with that of the nonasthmatic M1M1 individuals. Functional deficiency of alpha 1PI may be important in the pathogenesis of the inflammatory process that characterizes bronchial asthma.

Bilateral pleural effusions associated with generalized primary lymphoedema and erysipelas. A case report and the probable pathogenesis.

A case of bilateral pleural effusion in association with generalized primary lymphoedema and erysipelas, but without yellow dystrophic nails, is reported and the probable pathogenesis of the condition discussed. It is known that the primary defect lies in decreased lymphatic drainage. However, the consequent intravascular hypovolaemia and secondary hyperaldosteronism have not previously been demonstrated.

Aspergillus pneumonia--a cluster of four cases in an intensive care unit.

Four cases of Aspergillus pneumonia occurred in an intensive care unit within a short period. Clusters of cases of invasive aspergillosis are rare and have usually been attributed to excessive contamination of the environment. Extensive environmental studies were, however, negative. Three of the cases were diagnosed ante mortem. One patient survived after early initiation of treatment with amphotericin B.

Progressive systemic sclerosis complicated by diffuse pulmonary haemorrhage.

A case is reported of progressive systemic sclerosis with pulmonary fibrosis which was complicated by recurrent haemoptyses due to diffuse pulmonary haemorrhage. We have found no other report of this association. The haemorrhage finally remitted after treatment was started with 40 mg prednisone daily, though previously spontaneous remissions had occurred.
