UNLABELLED Aspirin-induced asthma (AIA) is a clinical syndrome characterized by acute airway reaction to aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDS). The most recent etiological hypothesises is that an overexpression of the enzyme LTC(4) synthase occurs in AIA, with the consequent production of sulfidopeptide leukotrienes (LTs). AIM(More)
This study tested the hypothesis that cimetidine and ranitidine, the new H2-antagonist, may influence the pharmacokinetics of theophylline administered i.v. at two different doses (3.4 and 6.5 mg/kg body wt.). Twenty hospitalized patients with chronic obstructive lung disease (COLD) and peptic ulcer were administered cimetidine or ranitidine orally for 8(More)
BACKGROUND Gastro-oesophageal reflux is regarded as an asthma trigger, its prevalence, in asthma, still being uncertain. AIM Purpose of the study was to assess the prevalence of gastro-oesophageal reflux in adult asthma patients. PATIENTS A series of 37 asthmatics were recruited consecutively over 6 months. Subjects were: 19 atopic (5 males; 38.0 years(More)
The effects resulting from the administration of therapeutic doses (1,200 mg/day for 8 days) of miocamycin, a novel macrolid derived from midecamycin, on theophylline elimination kinetic were investigated on 25 patients affected with chronic obstructive pathology on the respiratory tract. The curves of theophylline clearance, recorded before and after the(More)
The study, which was of a double-blind, crossover type vs placebo in 12 subjects suffering from postmenopausal osteoporosis and chronic asthma, evaluates the effects of acute, prolonged administration of salmon calcitonin (sCT) nasal spray on respiratory function (FEV1, MMEF, V25). No significant changes in bronchomotor tone were observed as a result of(More)
Bicycle ergometer exercise tests were used to study two groups of 10 subjects suffering from type A chronic respiratory insufficiency before and after a 4-week course of L-carnitine or placebo. Analysis of the ventilatory and metabolic response to physical exercise (60 watts) revealed an improved utilization of the bio-energetic substrates obtained with(More)
Inhaled nonisotonic solutions (e.g., ultrasonically nebulized distilled water, UNDW) are sensitive bronchoconstrictive agents in asthmatics, their suggested mechanism of action being the release of mediators from some inflammatory cells. Studies assessing the relationship between degree of bronchial hyperresponsiveness to UNDW and plasma levels of(More)
Over the last 2 years we have applied a therapeutic regimen with simultaneous use of cephalexin and bromhexine in therapy for infective exacerbations of COLD patients. The results obtained are positive. Bacteriologic features, the modification of sputum and, where possible, behavior of hematologic parameters and blood gases were checked. This pharmacologic(More)
Theophylline plasma levels and FEV1 were measured in patients affected by chronic obstructive pulmonary disease and a concomitant disease state (congestive heart failure, chronic cor pulmonale, obesity, peptic disease, hepatic cirrhosis, chronic renal failure) and treated with a sustained release theophylline preparation. Our results indicate that, only in(More)
