Metabolic effects of salbutamol: comparison of aerosol and intravenous administration.

The effects of intravenous salbutamol (4 mug/kg) were compared with those of aerosol salbutamol (200 mug) in 10 asthmatic patients in a double-blind placebo-controlled study. Both methods of administration produced equal bronchodilatation. Intravenous salbutamol caused significant increases in plasma insulin and glucose levels and a fall in serum potassium concentration in addition to tachycardia and tremor, whereas aerosol salbutamol produced only a small transient increase in the plasma glucose level. The initially raised non-esterified fatty acid levels decreased significantly after aerosol and placebo but not after intravenous salbutamol.

Extrinsic allergic alveolitis and contaminated cooling-water in a factory machine.

Symptoms and signs typical of extrinsic allergic alveolitis occurred in 24 workers in a stationery factory. The illness was caused by inhalation of a water aerosol contaminated by microorganisms, and although no specific organism has been incriminated, affected workers had serum precipitins to the contaminated water, and the illness could be reproduced by inhalation challenge tests.

Hyposensitisation with house dust mite vaccine in bronchial asthma.

In a double-blind placebo-controlled trial of tyrosine-absorbed Dermatophagoides pteronyssinus vaccine no improvement was seen in 45 patients with asthma sensitive to house dust mite. In particular there was no significant improvement in symptom scores, spirometry, and skin and nasal challenge test results. Some patients in other studies have benefited from doses of vaccine much stronger than those now commercially available, but the incidence of side effects has also been high.

Comparison of intravenous AH 5158 (ibidomide) and propranolol in asthma.

The cardiac and bronchial effects of AH 5158 and propranolol were compared in a double-blind, placebocontrolled intravenous study on 10 asthmatics. AH 5158, like propranolol, is a non-cardioselective beta-adrenoceptor-blocking drug, but unlike propranolol it also has an alpha-adrenoceptor-blocking action. Both drugs produced equivalent cardiac(beta1) blockade, but propranolol produced bronchoconstriction, whereas AH 5158 did not. Hence the alpha-blocking action of AH 5158 seems to prevent the bronchoconstrictor effects of propranolol in these patients.

Pulmonary function in asthmatic patients in remission.

Thirty-five asthmatic patients (average age 28 years) who attended a pulmonary function laboratory when their mean ratio of forced expiratory volume in one second: forced vital capacity was 81 per cent (within the normal range for their age group) had arterial hypoxaemia and hypocapnia. These were probably secondary to lung hyperinflation and pulmonary ventilation/perfusion imbalance. The pulmonary abnormalities of bronchial asthma are not always detected by simple spirometric tests and the results of such tests should be interpreted cautiously.
