Anti-inflammatory effects of atorvastatin treatment in chronic obstructive pulmonary disease. A controlled pilot study
Observational studies have suggested that statins may have beneficial effects on outcomes in chronic obstructive pulmonary disease (COPD) patients. These effects may be mediated through an anti-inflammatory effect of statins. The purpose of this pilot-study was to determine whether statins have an anti-inflammatory effect on the lungs of COPD patients. We conducted randomized, controlled, parallel group pilot-study to compare the effects of atorvastatin (n=12) or placebo (n=6) on lung inflammation in patients with mild to moderate COPD. The primary endpoint was change in CD45+ cells expression measured by immunohistochemistry and changes in expression of genes measured using microarrays in lung biopsy (TBB) samples before and after 12 weeks of treatment with atorvastatin 40 mg/day. All subjects had spirometry, lung volumes, diffusing capacity of the lungsfor carbon monoxide (DLCO), St George's Respiratory Questionnaire (SGRQ), 6 minute walk distance (6MWD), serum lipids, hs-CRP, induced sputum (IS), bronchoscopy and TBB carried out at baseline and after treatment. TBB specimens were processed for histology, immunohistochemistry and genome-wide association studies (GWAS) profiling. Seventeen subjects completed the study. There was a significant improvement in SGRQ with mean SGRQ decreased by 12 points after treatment with atorvastatin (P=0.012). Atorvastatin treatment produced a significant 34% reduction in sputum neutrophil count, and a 57% reduction in CD45+ cells in lung biopsies (expressed as integrated optical density -IOD; median IOD 62.51% before, 27.01% after atorvastatin treatment, P=0.008). In patients' lung tissue atorvastatin treatment produced downregulation of key genes involved in inflammatory processes, immune response, and leukocyte activation. These data demonstrate the pulmonary anti-inflammatory effects of atorvastatin in COPD patients with the potential for beneficial clinical effects. Trial Registration: ClinicalTrials.gov: NCT01748279
Effect of on-pump versus off-pump coronary bypass surgery on cardiac function assessed by intraoperative transesophageal echocardiography
Parameters influencing in-hospital mortality in patients hospitalized in intensive cardiac care unit: is there an influence of anemia and iron deficiency?
Prolonged antithrombotic therapy in patients after acute coronary syndrome : A critical appraisal of current European Society of Cardiology guidelines
The increased risk of non-cardiovascular death in patients receiving clopidogrel or prasugrel in comparison with the placebo group in the Dual Antiplatelet Therapy (DAPT) trial in contrast to the decreased risk of cardiovascular death and all-cause death seen in patients treated with low-dose ticagrelor in the EU label population of the PEGASUS-TIMI 54 trial, resulted in inclusion in the 2020 ESC NSTE-ACS guidelines the recommendation for use of clopidogrel or prasugrel only if the patient is not eligible for treatment with ticagrelor. The prevalence of the primary outcome composed of cardiovascular death, stroke, or myocardial infarction was lower in the low-dose rivaroxaban and acetylsalicylic acid (ASA) group than in the ASA-alone group in the COMPASS trial. Moreover, all-cause mortality and cardiovascular mortality rates were lower in the rivaroxaban-plus-ASA group. Comparison of the PEGASUS-TIMI 54 and COMPASS trial patient characteristics clearly shows that each of these treatment strategies should be addressed at different groups of patients. A greater benefit in post-acute coronary syndrome (ACS) patients with a high risk of ischemic events and without high bleeding risk may be expected with ASA and ticagrelor 60 mg b.i.d. when the therapy is continued without interruption or with short interruption only after ACS. On the other hand, ASA and rivaroxaban 2.5 mg b.i.d. seems to be a better option when indications for dual antithrombotic therapy (DATT) appear after a longer time from ACS (more than 2 years) and/or from cessation of DAPT (more than 1 year) and in patients with multiple vascular bed atherosclerosis. Thus, both options of DATTs complement each other rather than compete, as can be presumed from the recommendations. However, a direct comparison between these strategies should be tested in future clinical trials
