Coughing is a frequent side-effect of angiotensin converting enzyme (ACE) inhibitors. Its pathogenesis is thought to be related to the local accumulation of tachykinins although the role of extrinsic cholinergic pathways is unclear. The development of an ACE inhibitor induced cough in two patients who have undergone heart–lung transplantation and in whom cholinergic pathways remain denervated supports the hypothesis of a 'local' mechanism. 相似文献

Abstract. Papadopoulos KI, Melander O, Orho‐Melander M, Groop LC, Carlsson M, Hallengren B (University of Lund, Malmö University Hospital, Malmö, Sweden). Angiotensin converting enzyme (ACE) gene polymorphism in sarcoidosis in relation to associated autoimmune diseases. J Intern Med 2000; 247: 71–77. Objectives. To investigate the significance of ACE gene insertion/deletion (I/D) polymorphism in the frequency of autoimmune manifestations in sarcoidosis. Design. In patients with sarcoidosis the ACE gene I/D polymorphism was detected with PCR on genomic DNA. The patients with sarcoidosis were divided according to the presence (n = 30) or absence (n = 32) of autoimmune manifestations. The former group was subdivided into thyroid autoimmunity (n = 10), gluten immune reactivity (n = 10) and gastric autoimmunity (n = 17). Settings. The patients were recruited at the Department of Pulmonary Medicine, and the study was conducted at the Department of Endocrinology, University of Lund, Malmö University Hospital, Malmö, Sweden. Subjects. Sixty‐two patients with documented sarcoidosis (30 females, 32 males, median age/range at diagnosis of sarcoidosis 31.5/19–75 years, median age/range at study 47.5/22–81 years) were examined. A total of 107 healthy unrelated subjects without sarcoidosis (60 females, 47 males, median age/range at study 58/40–82 years) served as controls. Results. S‐ACE values were significantly increased in patients compared to controls (P = 0.00001). The same was true in the subgroup of sarcoidosis patients with associated autoimmunity compared with those with isolated sarcoidosis (P = 0.0328). A significant association was seen between ACE gene polymorphism (II, ID, DD genotypes) and S‐ACE levels in both patients and controls according to the order II < ID < DD. The observed genotype frequency distributions in the different study groups agreed the Hardy–Weinberg equilibrium without significant differences between the patients and the controls. Within the group with autoimmune manifestations the DD genotype was significantly over‐represented in X‐ray stage III compared to the other X‐ray stages (P = 0.0181) and a significant increase in the DD genotype in X‐ray stage III (P = 0.035) in the group with autoimmune manifestations compared to isolated sarcoidosis was detected. Conclusion. We confirmed that the S‐ACE levels corresponded to the order II < ID < DD in patients with sarcoidosis as well as in healthy controls. S‐ACE levels were significantly higher in sarcoidosis patients with autoimmune manifestations. The frequency of the DD genotype was significantly increased in patients with autoimmune manifestations and major granuloma mass (X‐ray stage III). The ACE D allele in its homozygous form may confer susceptibility for autoimmune manifestations in sarcoidosis, possibly via the high levels of S‐ACE it encodes. 相似文献

Background:We performed a meta-analysis to determine whether a consistent relationship exists between the use of angiotensin converting enzyme inhibitors (ACEIs) and the risk of lung cancer. Accordingly, we summarized and reviewed previously published quantitative studies.Methods:Eligible studies with reference lists published before June 1st, 2019 were obtained from searching several databases. Random effects’ models were used to summarize the overall estimate of the multivariate adjusted odds ratios (ORs) with 95% confidence intervals (CIs)Results:Thirteen observational studies involving 458,686 ACEI users were included in the analysis, Overall, pooled risk ratios indicate that ACEIs use was not a risk factor for lung cancer (RR 0.982, 95% C.I. 0.873 – 1.104; P = .76). There was significant heterogeneity between the studies (Q = 52.54; P < .001; I2 = 86.07). There was no significant association between ACEIs use and lung cancer in studies with over five years of ACEIs exposure (RR 0.95, 95% C.I. 0.75 – 1.20; P = .70); and ≤ 5years of exposure to ACEIs (RR 0.98, 95% C.I. 0.83 – 1.15; P = .77). There were no statistically significant differences in the pooled risk ratio obtained according to the study design (Q = 0.65; P = .723) and the comparator regimen (Q = 3.37; P = .19).Conclusions:The use of ACEIs was not associated with an increased risk of lung cancer. Nevertheless, well-designed observational studies with different ethnic populations are still needed to evaluate the long-term (over 10 years) association between ACEIs use and lung cancer. 相似文献

OBJECTIVE—To determine whether inhibition of angiotensin converting enzyme (ACE) can prevent angiotensin II production in the coronary circulation induced by percutaneous transluminal coronary angioplasty (PTCA) in patients with myocardial ischaemia.
DESIGN, PATIENTS—41 patients who underwent elective PTCA and six control subjects who received diagnostic coronary angiography were studied. Patients were divided into two groups according to the chronic administration of ACE inhibitors (group A, 15 patients treated with ACE inhibitors; group B, 26 patients without ACE inhibitors). Blood samples were drawn through catheters placed in the aorta and coronary sinus before and 24 hours after PTCA.
RESULTS—Mean levels of ACE activity in the aorta were significantly lower in patients in group A than in group B. However, mean angiotensin II concentrations in the aorta were not significantly different between the two groups. Differences in basal angiotensin II concentrations between the coronary sinus and aorta, which reflected basal angiotensin II production in the coronary circulation, were not significant among group A, group B, and control subjects. The production of angiotensin II in the coronary circulation was significantly increased 24 hours after PTCA in both group A and group B to the same extent. No significant changes were observed in control subjects 24 hours after diagnostic coronary angiography.
CONCLUSIONS—This study revealed that inhibition of ACE activity by ACE inhibitors could not prevent increases in angiotensin II production in the coronary circulation induced by PTCA.

OBJECTIVES: The aim of this study was to test for genetic linkage and association between polymorphisms of the angiotensin-converting enzyme (ACE) gene and familial occurrence of sarcoidosis. DESIGN, SETTING AND SUBJECTS: German families with more than one member suffering from sarcoidosis were contacted and a DNA bank was established. Sixty-two families (140 patients, 77 females and 63 males, and 104 unaffected relatives) were genotyped for the ACE gene insertion/deletion (I/D) polymorphism and for two flanking variable sites (ACE A-5466C and ACE 4656(CT)2/3). As controls, 100 DNAs from unrelated resident Caucasians (50 females, 50 males) were analysed. ACE allele and genotype frequencies were determined, and parametric linkage and affected sib pair analyses and transmission disequilibrium tests were performed. RESULTS: There was a striking over-representation of the ACE I/D genotype DD in patients with sarcoidosis and their families as compared with controls of the study and well founded genotype frequencies from the literature. The same was evident for the accompanying genotypes CC and 2,2 of the flanking polymorphisms. Linkage between the segregation of ACE alleles and the disorder within families was clearly excluded for simple models of inheritance. However, there was a suggestive but not significant (P = 0.06) excess of allele sharing amongst affected siblings. There was no transmission disequilibrium for any ACE allele or haplotype. CONCLUSIONS: ACE is involved in the pathogenesis of sarcoidosis, but the ACE polymorphisms are not an inherited main cause of the disease. They are more likely to modify the development of the disorder, and the ACE I/D genotype DD might be a promoter to clinical manifestation. 相似文献

Purpose The renin-angiotensin system plays a crucial role in maintaining vascular homeostasis. Stimulation of angiotensin II type
1 receptors (AT1R) acts proangiogenically by increasing levels of vascular endothelial growth factor (VEGF). Consequently,
cell culture experiments and animal studies have shown antiproliferative effects of AT1R blockers (ARB) and angiotensin I
converting enzyme inhibitors (ACEI) in several malignancies. Until now, very limited clinical data for this antiangiogenic
effect exists for combinations with antineoplastic chemotherapy.
Methods A total of 287 patients with advanced non-small-cell lung cancer undergoing first-line platinum-based chemotherapy were retrospectively
analysed regarding long-term medication with ACEI and ARB as well as histological type, stage, performance status, gender,
age, dose-intensity of chemotherapy and survival.
Results Patients receiving either ACEI or ARB had a 3.1 months longer median survival than non-recipients (11.7 vs. 8.6 months, HR
0.56, P = 0.03). This survival advantage could not be attributed to other established risk-factors or dose intensity of chemotherapy.
Conclusions Addition of ACEI or ARB to platinum-based first-line chemotherapy may contribute to prolonged survival in patients with advanced
lung cancer. 相似文献

Objective There is little population-based data on the prevalence and the environmental or genetic determinants of left ventricular hypertrophy (LVH) in China. The purpose of this paper is to study LVH in relation to systolic blood pressure and the angiotensin converting enzyme (ACE) insertion/deletion(I/D) polymorphism in Chinese. Methods We recorded 12- lead ECG (CardioSoft, v4.2) in 1365 residents in the Jingning County, Zhejiang Province, China. LVH was defined according to the gender-specific Sokolow-Lyon and Cornell product ECG criteria. Results Regardless of whether the Sokolow-Lyon or Cornell product ECG criteria was used, the prevalence of LVH (20.7% and 4.8%, respectively) significantly (P〈0.0001) increased with male gender (odds ratio [OR] 2.33 and 7.15) and systolic blood pressure (per 10 mm Hg increase, OR 1.46 and 1.33). If the Sokolow-Lyon criteria was used, the prevalence of LVH was also influenced by alcohol intake (OR 1.44, P=-0.03) and body mass index (OR 0.83, P=0.0005). The association between the Sokolow-Lyon voltage amplitude and the ACE I/D polymorphism was dependent on antihypertensive therapy (P=0.01). In 1262 untreated subjects, but not 103 patients on antihypertensive medication, the ACE DD compared with II subjects had significantly higher Sokolow-Lyon voltage amplitudes (29.8:-0.6 vs. 28.0-3:0.5 mV, P=-0.02) and higher risk of LVH (OR 1.74, 95% CI: 1.12-2.69, P=-0.01). Conclusion LVH is prevalent in Chinese, and is associated with systolic blood pressure and the ACE D allele. The genetic association might be modulated by antihypertensive therapy(J Geriatr Cardio12009; 6:131-136). 相似文献
