A systematic review and network meta-analysis of the comparative efficacy of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in hypertension. J Hum Hypertens 2018; 33:188-201. [PMID: 30518809 DOI: 10.1038/s41371-018-0138-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2018] [Revised: 11/06/2018] [Accepted: 11/15/2018] [Indexed: 01/13/2023]
Abstract
Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are drugs commonly used for the treatment of hypertension. However, studies on their comparative efficacy have not been extensively investigated. The current systematic review and network meta-analysis studied the comparative efficacy of the two antihypertensive treatment categories in reducing blood pressure, mortality, and morbidity in essential hypertension patients. A literature search was carried out in Medline and Cochrane Central Register of Controlled Trials for placebo- and active-controlled, double-blind randomized clinical trials, which had reported blood pressure effects, mortality, and/or morbidity. Blood pressure results were found in 30 studies with 7370 participants and 8 studies with 25,158 participants with mortality/morbidity results included in the analysis. The two drug classes had similar effectiveness in lowering systolic (weighted mean difference (WMD): 0.59, 95% CI: -0.21 to 1.38) and diastolic blood pressure (WMD: 0.62, 95% CI: -0.06 to 1.30), all-cause mortality (risk ratio (RR)): 0.96, 95% CI 0.80 to 1.14), cardiovascular mortality (RR: 0.87, 95% CI 0.67 to 1.14), fatal and non-fatal myocardial infarction (RR: 1.02, 95% CI 0.75 to 1.37) and stroke (RR: 1.13, 95% CI 0.87 to 1.46). Angiotensin-converting enzyme inhibitors were more helpful in the prevention and/or the hospitalization for heart failure than angiotensin receptor blockers (RR: 0.71, 95% CI 0.54 to 0.93). Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers were similarly effective in decreasing blood pressure, mortality, and morbidity in essential hypertension. Angiotensin-converting enzyme inhibitors were more protective in the advancement and/or hospitalization of the hypertensive patient for heart failure than angiotensin receptor blockers.

High molecular weight fibroblast growth factor-2 in the human heart is a potential target for prevention of cardiac remodeling. PLoS One 2014; 9:e97281. [PMID: 24827991 PMCID: PMC4020823 DOI: 10.1371/journal.pone.0097281] [Citation(s) in RCA: 50] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2013] [Accepted: 04/18/2014] [Indexed: 11/18/2022] Open
Abstract
Fibroblast growth factor 2 (FGF-2) is a multifunctional protein synthesized as high (Hi-) and low (Lo-) molecular weight isoforms. Studies using rodent models showed that Hi- and Lo-FGF-2 exert distinct biological activities: after myocardial infarction, rat Lo-FGF-2, but not Hi-FGF-2, promoted sustained cardioprotection and angiogenesis, while Hi-FGF-2, but not Lo-FGF-2, promoted myocardial hypertrophy and reduced contractile function. Because there is no information regarding Hi-FGF-2 in human myocardium, we undertook to investigate expression, regulation, secretion and potential tissue remodeling-associated activities of human cardiac (atrial) Hi-FGF-2. Human patient-derived atrial tissue extracts, as well as pericardial fluid, contained Hi-FGF-2 isoforms, comprising, respectively, 53%(±20 SD) and 68% (±25 SD) of total FGF-2, assessed by western blotting. Human atrial tissue-derived primary myofibroblasts (hMFs) expressed and secreted predominantly Hi-FGF-2, at about 80% of total. Angiotensin II (Ang II) up-regulated Hi-FGF-2 in hMFs, via activation of both type 1 and type 2 Ang II receptors; the ERK pathway; and matrix metalloprotease-2. Treatment of hMFs with neutralizing antibodies selective for human Hi-FGF-2 (neu-AbHi-FGF-2) reduced accumulation of proteins associated with fibroblast-to-myofibroblast conversion and fibrosis, including α-smooth muscle actin, extra-domain A fibronectin, and procollagen. Stimulation of hMFs with recombinant human Hi-FGF-2 was significantly more potent than Lo-FGF-2 in upregulating inflammation-associated proteins such as pro-interleukin-1β and plasminogen-activator-inhibitor-1. Culture media conditioned by hMFs promoted cardiomyocyte hypertrophy, an effect that was prevented by neu-AbHi-FGF-2 in vitro. In conclusion, we have documented that Hi-FGF-2 represents a substantial fraction of FGF-2 in human cardiac (atrial) tissue and in pericardial fluid, and have shown that human Hi-FGF-2, unlike Lo-FGF-2, promotes deleterious (pro-fibrotic, pro-inflammatory, and pro-hypertrophic) responses in vitro. Selective targeting of Hi-FGF-2 production may, therefore, reduce pathological remodelling in the human heart.

Multidisciplinary pharmacotherapeutic options for nonalcoholic Fatty liver disease. Int J Hepatol 2012; 2012:950693. [PMID: 23304532 PMCID: PMC3523542 DOI: 10.1155/2012/950693] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2012] [Accepted: 11/13/2012] [Indexed: 12/22/2022] Open
Abstract
Nonalcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are multidisciplinary liver diseases that often accompany type 2 diabetes or metabolic syndrome, which are characterized by insulin resistance. Therefore, effective treatment of type 2 diabetes and metabolic syndrome should target not only the cardiometabolic abnormalities, but also the associated liver disorders. In the last decade, it has been shown that metformin, thiazolidinediones, vitamin E, ezetimibe, n-3 polyunsaturated fatty acids, renin-angiotensin system (RAS) blockers, and antiobesity drugs may improve hepatic pathophysiological disorders as well as clinical parameters. Accordingly, insulin sensitizers, antioxidative agents, Niemann-Pick C1-like 1 (NPC1L1) inhibitors, RAS blockers, and drugs that target the central nervous system may represent candidate pharmacotherapies for NAFLD and possibly NASH. However, the efficacy, safety, and tolerability of long-term treatment (potentially for many years) with these drugs have not been fully established. Furthermore, clinical trials have not comprehensively examined the efficacy of lipid-lowering drugs (i.e., statins, fibrates, and NPC1L1 inhibitors) for the treatment of NAFLD. Although clinical evidence for RAS blockers and incretin-based agents (GLP-1 analogs and dipeptidyl peptidase-4 inhibitors) is also lacking, these agents are promising in terms of their insulin-sensitizing and anti-inflammatory effects without causing weight gain.

Timing of captopril administration determines radiation protection or radiation sensitization in a murine model of total body irradiation. Exp Hematol 2010; 38:270-81. [PMID: 20116413 DOI: 10.1016/j.exphem.2010.01.004] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2010] [Revised: 01/05/2010] [Accepted: 01/20/2010] [Indexed: 02/07/2023]
Abstract
OBJECTIVE Angiotensin II (Ang II), a potent vasoconstrictor, affects the growth and development of hematopoietic cells. Mixed findings have been reported for the effects of angiotensin-converting enzyme (ACE) inhibitors on radiation-induced injury to the hematopoietic system. We investigated the consequences of different regimens of the ACE inhibitor captopril on radiation-induced hematopoietic injury. MATERIALS AND METHODS C57BL/6 mice were either sham-irradiated or exposed to (60)Co total body irradiation (0.6 Gy/min). Captopril was provided in the water for different time periods relative to irradiation. RESULTS In untreated mice, the survival rate from 7.5 Gy was 50% at 30 days postirradiation. Captopril treatment for 7 days prior to irradiation resulted in radiosensitization with 100% lethality and a rapid decline in mature blood cells. In contrast, captopril treatment beginning 1 hour postirradiation and continuing for 30 days resulted in 100% survival, with improved recovery of mature blood cells and multilineage hematopoietic progenitors. In nonirradiated control mice, captopril biphasically modulated Lin(-) marrow progenitor cell cycling. After 2 days, captopril suppressed G(0)-G(1) transition and a greater number of cells entered a quiescent state. However, after 7 days of captopril treatment Lin(-) progenitor cell cycling increased compared to untreated control mice. CONCLUSION These findings suggest that ACE inhibition affects hematopoietic recovery following radiation by modulating the hematopoietic progenitor cell cycle. The timing of captopril treatment relative to radiation exposure differentially affects the viability and repopulation capacity of spared hematopoietic stem cells and, therefore, can result in either radiation protection or radiation sensitization.
