The non-specific bronchial reactivity and cough threshold of hypertensive patients on an ACE-I monotherapy regimen (either captopril or enalapril), a beta 1-antagonist monotherapy regimen (either atenolol or metoprolol) or a combination of an ACE-I with a beta 1-antagonist were determined in the present study. Forty-six hypertensives who were on these medications performed a histamine inhalation test (to assess bronchial reactivity) and a further 36 of these individuals participated in the citric acid test (to assess cough threshold). A control cohort consisting of 25 age-matched, drug-free subjects also performed the citric acid test. The incidence of bronchial hyperreactivity was not significantly different between the ACE-I monotherapy regimen and the beta 1-antagonist monotherapy regimen (Chi-squared = 0.248). However, when the monotherapy regimens were pooled and compared with the ACE-I and beta 1-antagonist combination regimen, the combination regimen was found to be associated with a significantly higher incidence of bronchial hyperreactivity (Chi-squared = 6.69). No difference was observed between the age-matched controls and the hypertensive patients in terms of their cough threshold.

The effect of sulindac on ACE inhibitor-induced cough was studied in eight hypertensive subjects in a randomised placebo-controlled double blind cross-over trial. There was no significant improvement in cough or sense of well-being. Blood pressure, renal function, plasma renin and ACE activity were unchanged. Sulindac however, appears to be effective in some individuals in reducing ACE inhibitor-induced cough with acceptable tolerance and few side effects. Further work is needed to elucidate the mechanism of sulindac's interaction with ACE inhibitors.

In view of the pharmacological and chemical reasons for using ACE-inhibitors to treat diabetic hypertension, a group of 40 outpatients were treated with Enalapril. The sample consisted of 20 outpatients, 6 males, 14 females aged 48-76 (mean age 63.75), 18 of whom had type II and 2 type I diabetes and 11 under treatment by diet and hypoglycaemic drugs or insulin. All these patients presented slight or moderate essential arterial hypertension (diastolic pressure less than 115 mmHg). For about one year 17 of the patients were given 20 mg/die Enalapril and the remaining three 10 mg/die in a single morning dose. In 16 cases no other treatment was given. In 4 a non-potassium conserving diuretic was also given. Check-ups before six months into and at the end of treatment showed: a statistically significant reduction in systolic (p less than 0.05) and diastolic (p less than 0.01) pressure. In contrast no significant change was noted in heart beat, glycaemia before or after meals, body weight, glycosylated haemoglobin or any other blood chemical parameter considered. In one case only there was a slight increase in proteinuria that was however present at the start of treatment. As far as side effects are concerned there was one case of cardiac palmus during treatment and one case of coughing that regressed totally when treatment was suspended but nothing else of significance. It should be noted that the antidiabetic treatment remained unchanged throughout the period considered in most cases and at most was subjected to minimal qualitative and quantitative adjustments.

The relationship between angiotensin converting enzyme inhibitors (ACE inhibitors) and the development of cough was studied in 80 patients. Cough developed in 25 (31%). Seventeen patients had detailed respiratory investigations of whom 12 developed a new cough. Five of the 12 patients had a remission on placebo and recurrence on rechallenge. Cough does occur with ACE inhibitors but there are other possible causes of cough such as asthma, bronchitis, smoking and heart failure. The true incidence of new cough with ACE inhibitors is uncertain at present.

A traditional Chinese remedy, Qing-Fei-Tang (Seihai-to, T90), has been used for treatment of chronic respiratory diseases with long-lasting cough and sputum, e.g. chronic bronchitis. We examined the effect of T90 and its main component flavonoid, baicalein, on the lucigenin-dependent chemiluminescence (CL) and leukotriene B4 (LTB4) synthesis of human alveolar macrophages (AM). AM were obtained by bronchoalveolar lavage from patients with various respiratory diseases, including sarcoidosis, idiopathic pulmonary fibrosis, bronchial asthma, chronic bronchitis and lung cancer. CL were observed by stimulating 1 x 10(5) AM with phorbol myristate acetate in the presence of lucigenin. LTB4 were generated by incubating 1 x 10(6)/ml AM with Ca ionophore A23187 for 30 min and determined by reverse phase high performance liquid chromatography and radioimmunoassay. T90 (0.2-2.0 mg/ml) and baicalein (0.1-100 microM) inhibited both CL and LTB4 production of AM in a dose-dependent fashion. These inhibitory effects were not due to cytotoxic effects of the procedure because neither 2 mg/ml T90 nor 100 M baicalein affected the viability of AM nor lactate dehydrogenase release from AM. These results suggest that T90 exerts its effect on inflammatory lung diseases through the anti-inflammatory action, i.e. inhibiting the oxidative and arachidonate metabolism of local inflammatory lung cells.

Chronic obstructive pulmonary disease (COPD) is equated with chronic bronchitis and emphysema as one disease entity. In COPD airflow limitation is relatively persistent--unlike asthma. Tests for "small-airways disease" form no part of routine practice, for their accuracy in detecting pathological change is debatable. The proteolytic theory of the pathogenesis of emphysema highlights the role of neutrophil elastase, antielastases, oxidants, antioxidants, and thus of potential new treatments. Clinical features of COPD include breathlessness, cough, and sputum, with airflow obstruction and lung hyperinflation. The differential diagnosis includes bronchiectasis, cystic fibrosis, and pulmonary hypertension, but pulmonary fibrosis, etc., is distinguished by radiological infiltrates. Plain chest radiography cannot reliably diagnose emphysema in life, but a new method measuring lung density from the computed tomographic (CT) scan allows location, quantitation, and diagnosis of emphysema (defined by enlargement of distal air spaces) in humans in life. "Pink puffers" with breathlessness, hyperinflation, mild hypoxemia, and a low PCO2 are contrasted with "blue bloaters" with hypoxemia, secondary polycythemia, CO2 retention, and pulmonary hypertension and cor pulmonale. Antismoking measures are a major aim in management. A bronchodilator regimen combining a slow-release oral theophylline with an inhaled beta 2-agonist, ipratropium, and high-dose inhaled steroids is proposed because even modest improvement in obstruction can help these patients. In acute exacerbations with purulent sputum, antimicrobials against Streptococcus pneumoniae and Hemophilus influenzae are used with controlled oxygen therapy aiming to keep the arterial PO2 over 50 mm Hg without the pH falling below 7.25. Influenza prophylaxis is recommended, but pneumococcal vaccination remains debatable. Chronic under-nutrition in "emphysema" implies controlled trials of feeding regimens--but these remain to be assessed. Long-term oxygen therapy is the only treatment known to prolong life in blue bloaters, and oxygen concentrators and transtracheal oxygen delivery are discussed. Pulmonary vasodilators (e.g., beta 2-agonists, hydralazine, nifedipine, angiotensin-converting enzyme [ACE] inhibitors, etc.) have not yet been proved to provide long-term reduction in pulmonary arterial pressure. Blue bloaters have severe nocturnal hypoxemia in rapid eye movement (REM) sleep that is corrected by oxygen or the investigational drug almitrine.(ABSTRACT TRUNCATED AT 400 WORDS)

Since their introduction in clinical practice in 1980, ACE inhibitors have been found useful in the treatment of hypertension and CHF. In hypertension, they are effective as monotherapy in 40% to 50% of the patients, and in combination with diuretics or calcium antagonists, they are effective in up to 85% of the patients. They are well tolerated, are not associated with depression, impotence, bronchospasm or metabolic derangements such as hypokalemia, hyperuricemia or hyperglycemia, and do not have adverse effects on the quality of life. As a result, they are preferred in hypertensive patients with CHF, left ventricular dysfunction, mental depression, older age, coronary artery disease, metabolic disorders, chronic destructive pulmonary disease, and peripheral vascular disease. In CHF they cause long-lasting hemodynamic and symptomatic improvement, improve exercise tolerance, and may lower mortality in certain patient subsets. Evolving new indications for ACE inhibitors include the diagnosis of renovascular hypertension, the prediction of surgical success, the treatment of scleroderma renal crisis, the reduction of proteinuria, renal protection, cardioprotection, the improvement of arterial compliance, in Bartter's syndrome and idiopathic edema, etc. ACE inhibitors are usually well tolerated but in some instances they may cause class-specific side effects such as hypotension; usually reversible azotemia or renal failure, especially in patients with renal artery stenosis or with CHF with low blood pressure; cough; angioedema; and hyperkalemia. Differences among ACE inhibitors are emerging and include chemical class (e.g., zinc ligand), biotransformation, potency, pharmacokinetics, prodrugs, tissue effects, additional pharmacologic properties, and drug interactions.

A 32-year-old primigravida presented with cough and dyspnea at 16 weeks' gestation. Chest roentgenogram revealed a large pleural effusion and diffuse interstitial infiltrates. Moderate arterial hypoxemia and a significant reduction in vital capacity were present. Thoracentesis revealed sterile chyle with no evidence of malignancy. Spontaneous delivery of a healthy infant occurred at 38 weeks, but no change was seen in either the pulmonary infiltrates or chylothorax. Open lung biopsy confirmed the clinical impression of pulmonary lymphangiomyomatosis, and a pleurodesis was performed. Progesterone and estrogen receptor assays on the lung biopsy material revealed only minimal binding. Following two years of therapy with tamoxifen citrate and megestrol acetate, the chylothorax has not recurred, and there has been no other appreciable change in pulmonary function.

A double-blind, crossover, randomized, placebo-controlled chronotherapeutic study was designed in which eight patients (two men, 20 and 48 yr old, and six women, 22 to 58 yr old) suffering from corticosteroid-dependent allergic asthma were socially synchronized, with a diurnal activity from about 7:30 A.M. to about 11 P.M. and a nocturnal rest. During an 8 day span they were treated on a Dutimelan 8-15 regimen, labeled DTM 8-15: at 8 A.M. a pill containing 7 mg of prednisolone acetate and 4 mg of prednisolone alcohol, at 3 P.M. a pill with 15 mg of cortisone acetate and 3 mg of prednisolone alcohol, and a placebo at 8 P.M. During another 8 day span they were given a placebo at 8 A.M. and at 3 P.M. a pill with 15 mg of cortisone acetate and 3 mg of prednisolone alcohol and at 8 P.M. another pill with 7 mg of prednisolone acetate and 4 mg of prednisolone alcohol, a regimen labeled Rx 15-20. During wakefulness (between 7 A.M. and 11 P.M.), every 2 hr at eight fixed clock hours, peak expiratory flow (PEF), grip strength, and oral temperature were self-measured and dyspnea, cough, and fatigue were self-rated. The PEF 24 hr mean as well as the nocturnal dip were lower (p less than 0.05 to p less than 0.0005) with Rx 15-20 than with DTM 8-15, while the nocturnal increase of dyspnea was greater with Rx 15-20 than with DTM 8-15. Long-term administration of corticosteroids at 8 A.M. and 3 P.M. was more effective to control asthma and enhance PEF values than the same agents and dose given at 3 and 8 P.M.

Cough productive of sputum, exertional dyspnea, and hypoxemia developed in two patients with Graves' disease after six months (patient 1) or three weeks (patient 2) of treatment with propylthiouracil, 300 mg/day. Chest roentgenograms and transbronchial lung biopsy specimens revealed diffuse interstitial pneumonitis. Lymphocyte transformation by phytohemagglutinin was highly stimulated by propylthiouracil. Symptoms and signs improved after cessation of the drug therapy and administration of prednisolone acetate. These cases represent the first report of a complication of diffuse interstitial pneumonitis induced by propylthiouracil.
