Occupational, domestic and environmental mesothelioma risks in the British population: a case–control study

We obtained lifetime occupational and residential histories by telephone interview with 622 mesothelioma patients (512 men, 110 women) and 1420 population controls. Odds ratios (ORs) were converted to lifetime risk (LR) estimates for Britons born in the 1940s. Male ORs (95% confidence interval (CI)) relative to low-risk occupations for >10 years of exposure before the age of 30 years were 50.0 (25.8–96.8) for carpenters (LR 1 in 17), 17.1 (10.3–28.3) for plumbers, electricians and painters, 7.0 (3.2–15.2) for other construction workers, 15.3 (9.0–26.2) for other recognised high-risk occupations and 5.2 (3.1–8.5) in other industries where asbestos may be encountered. The LR was similar in apparently unexposed men and women (∼1 in 1000), and this was approximately doubled in exposed workers' relatives (OR 2.0, 95% CI 1.3–3.2). No other environmental hazards were identified. In all, 14% of male and 62% of female cases were not attributable to occupational or domestic asbestos exposure. Approximately half of the male cases were construction workers, and only four had worked for more than 5 years in asbestos product manufacture

Quality of life and cough on antihypertensive treatment: a randomised trial of eprosartan, enalapril and placebo.

The objective of this study was to compare the quality of life and incidence of dry cough with the angiotensin II antagonist eprosartan, the ACE-inhibitor enalapril, and placebo, in hypertensive patients with a history of ACE-inhibitor cough. The study was a multicentre, randomised, double-blind, parallel group controlled trial. A total of 136 patients judged to have ACE-inhibitor cough during single-blind enalapril treatment which was lost during a subsequent placebo washout phase, were randomised to receive either eprosartan 300 mg twice daily, or enalapril 20 mg once daily, or placebo for 6 weeks. Self-completion questionnaires assessing quality of life and cough were examined at baseline and end of study. At study end point 23% of patients in the enalapril group and 5% in the eprosartan and placebo groups reported cough (which included definite, probable and possible coughs) (P = 0.02). After adjusting for multiple comparisons, the eprosartan group was not significantly different from either placebo or enalapril. There were no significant differences in the Psychological General Wellbeing Index (PGWB). In conclusion the incidence of self-reported cough on eprosartan was similar to that on placebo, and lower than on enalapril but this difference was not significant when adjustments were made for multiple comparisons. There were no differences in quality of life

Comparison of quality of life and cough on eprosartan and enalapril in people with moderate hypertension.

The objective of this study was to compare quality of life and incidence of dry persistent cough among patients treated with eprosartan and enalapril for mild-moderate hypertension. This was a randomised 26-week double-blind controlled trial carried out in clinics in nine countries of North America, Europe and South Africa. A total of 529 patients aged 18 and over with diastolic blood pressure between 95 mm Hg and 114 mm Hg were studied. Treatment comprised of eprosartan or enalapril monotherapy for 12 weeks with the option of hydrochlorothiazide addition for the remaining 14 weeks. The primary outcome measures were cough and the Psychological General Wellbeing Index (PGWB) total and subscales (anxiety, self-control, depression, general health, positive wellbeing and vitality). The results were that 17.8% of enalapril patients and 13.2% of eprosartan patients withdrew from randomised treatment. Those on enalapril were twice as likely to have gained a definite or possible cough by study end point as those on eprosartan (7.6% vs 3.2%) P = 0.099. At monotherapy end point the differences were greater (9.9% vs 2.1%) and of statistical significance, P = 0.001. Patients treated with enalapril, however, had small but significant improvements in measures of self-control and total PGWB compared with those on eprosartan. The effect sizes of 0.2 or less indicated that there were small differences. In conclusion eprosartan was associated with fewer coughs than enalapril but it performed less well on some aspects of quality of life
