Nagasawa M. Pathophysiology of acute graft-versus-host disease from the perspective of hemodynamics determined by dielectric analysis. World J Transplant 2023; 13:379-390. [PMID: 38174146 PMCID: PMC10758686 DOI: 10.5500/wjt.v13.i6.379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 11/01/2023] [Accepted: 12/01/2023] [Indexed: 12/15/2023] Open
Abstract
BACKGROUND Numerous reports have demonstrated that the pathophysiology of graft-versus-host disease (GVHD) during hematopoietic stem cell transplantation (HSCT) is closely related to vascular endothelial disorders and coagulation abnormalities. We previously presented the discovery of a principle and the development of a novel instrument for measuring whole blood coagulation. This was achieved by assessing the variations in the dielectric properties of whole blood. AIM To investigate how GVHD affects the changes of dielectric properties of whole blood in patients with HSCT. METHODS We examined the changes of dielectric properties of whole blood and erythrocyte proteins by sodium dodecyl sulfate-polyacrylamide gel electrophoresis sequentially in patients with HSCT and compared it with clinical symptoms and inflammatory parameters of GVHD. RESULTS During severe GVHD, the dielectric relaxation strength markedly increased and expression of band3 decreased. The dielectric relaxation strength normalized with the improvement of GVHD. In vitro analysis confirmed that the increase of relaxation strength was associated with severe erythrocyte aggregates, but not with decreased expression of band3. CONCLUSION Severe erythrocyte aggregates observed in GVHD may cause coagulation abnor malities and circulatory failure, which, together with the irreversible erythrocyte dysfunction we recently reported, could lead to organ failure.

Cardiovasc Diabetol 2021; 20:207. [PMID: 34656122 PMCID: PMC8520235 DOI: 10.1186/s12933-021-01397-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 10/06/2021] [Indexed: 01/11/2023] Open
Abstract
Aims Previous studies suggested an adverse association between higher fasting blood glucose (FBG) variability and cardiovascular disease (CVD). Lifetime risk provides an absolute risk assessment during the remainder of an individual’s life. However, the association between FBG variability and the lifetime risk of CVD is uncertain. Objective We aimed to investigate the effect of the visit-to-visit FBG variability on the lifetime risk of CVD. Methods This study included participants from the Kailuan Study who did not have CVD at index ages 35, 45, and 55 years. The FBG variability was defined as the coefficient of variation (CV) of three FBG values that were measured during the examination periods of 2006–2007, 2008–2009, and 2010–2011. We used a modified Kaplan-Merrier method to estimate lifetime risk of CVD according to tertiles of FBG variability. Results At index age 35 years, the study sample comprised 46,018 participants. During a median follow-up of 7.0 years, 1889 participants developed CVD events. For index age 35 years, participants with high FBG variability had higher lifetime risk of CVD (32.5%; 95% confidence interval [CI]: 28.9–36.1%), compared with intermediate (28.3%; 95% CI: 25.5 –31.1%) and low (26.3%; 95% CI: 23.0–29.5%) FBG variability. We found that higher FBG variability was associated with increased lifetime risk of CVD in men but not women. Similar patterns were observed at index ages 45 and 55 years. Conclusions Higher FBG variability was associated with increased lifetime risk of CVD at each index age. Focusing on the FBG variability may provide an insight to the clinical utility for reducing the lifetime risk of CVD.

Nutrients 2020; 12:nu12040918.

Abstract
We have recently reported that patients with fibromyalgia (FM) may be at increased risk for cardiovascular disease. Olive oil reportedly has cardioprotective effects. We examined the influence of olive oil consumption on cardiovascular risk factors in FM. This preliminary study was performed on blood samples of women with FM who consumed 50 mL of organic olive oil daily for 3 weeks. Patients were randomized into two groups: 15 women ingested extra virgin olive oil (EVOO) and 15 refined olive oil (ROO). Cardiovascular risk markers were measured at baseline (pre measure) and after consumption of olive oil (post measure). Red blood cell count and erythrocyte sedimentation rate (ESR; both p < 0.05) declined significantly post-treatment in the EVOO group. Consumption of ROO increased mean platelet volume and reduced platelet distribution width (PDW), neutrophil-to-lymphocyte ratio, ESR and fibrinogen (all p < 0.05). Significant differences were found in pre–post change between the EVOO and ROO groups for cortisol and PDW (both p < 0.05). Our results have shown that consumption of olive oil may have antithrombotic and antiinflammatory properties in patients with FM, thereby improving a number of cardiovascular risk markers. Both EVOO and ROO may be useful as adjuvants for the prevention and/or treatment of cardiovascular disorders in these patients.

Abstract
Objectives: The aim of this study was to investigate thrombosis-related parameters (blood coagulation parameters, platelet indices, red blood cell [RBC] count, and inflammatory markers) in patients with fibromyalgia (FM). Method: We carried out a case–control study with 35 women with FM and 12 age-matched healthy volunteers to analyze fibrinogen levels, prothrombin time, cephaline time, platelet count, platelet distribution width (PDW), mean platelet volume (MPV), RBC count, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (PLR). Results: The results showed significantly increased fibrinogen levels ( p < .05), platelet count ( p < .05), PDW ( p = .059), RBC count ( p < .05), and PLR ( p < .05) in women with FM versus the healthy volunteers. Prothrombin time ( p < .05) and MPV ( p < .05) were significantly lower in patients with FM than in the controls. Conclusions: Elevated platelet and RBC counts, PDW values, and fibrinogen levels as well as decreased prothrombin time are all indicative of a prothrombotic state in FM patients, which may be enhanced by an increased inflammatory tone. This prothrombotic state may increase the risk of thrombosis-related cardiovascular disease in patients with FM.

Abstract
BACKGROUND Currently available therapeutic options for thromboembolic disorders are often very expensive and are associated with unfavorable side effects. AIM To establish the anticoagulant effect and safety profile of an extract made from of the root bark of Pseudocedrela kotschyi (Schweinf.) Harms and the aerial part of Adenia cissampeloides (Planch. ex Hook.) Harms (PAE). MATERIALS AND METHODS PAE (0.5-2.0 g/L) effect on prothrombin time (PT) and activated partial thromboplastin time (aPTT) were evaluated on whole blood drawn from the marginal ear vein of New Zealand White rabbits. Effect of PAE (250-2000 mg/kg) on bleeding time (BT) and clotting time (CT) in Sprague-Dawley rats were also assessed. Histopathological, hematological, and liver function studies were also carried out to assess the safety for use of PAE (250-2000 mg/kg). RESULTS PAE had no significant effect (P > 0.05) on PT, but resulted in a significant increase (P ≤ 0.05-0.0001) in aPTT. The PAE treatment resulted in a significant increase (P ≤ 0.05-0.0001) in BT and CT in vivo compared with control. Safety studies indicated no deaths with PAE treatment with hematological and liver function tests being normal. Histological studies revealed pathological changes in the liver at a PAE treatment dose of 2000 mg/kg but all doses had no detrimental effect on kidney and stomach tissue. The no-observed-adverse-effect-level was <2000 mg/kg when given orally. CONCLUSION PAE has anticoagulant effect in vitro and is safe to use at oral doses <2000 mg/kg.

Abstract
OBJECTIVE Thrombus and spontaneous echo contrast (SEC) develops in the left atrial appendage (LAA) when LAA function is disturbed. Decrease of left atrial appendage emptying velocity shows LAA dysfunction. The purpose of this study is to examine the incidence of SEC and/or thrombus in LAA in patients with acute myocardial infarction and to assess the LAA function using color Doppler tissue imaging (CDTI) of the patients with detected SEC and/or thrombus. METHOD AND RESULTS Eighty-four patients with acute myocardial infarction were included in the study. Spontaneous echo contrast and/or thrombus were observed in 24 (29%) of the 84 patients who were categorized as group 1 (mean age 59 +/- 12 years). Sixty patients (71%) without thrombus and/or SEC in LAA were categorized as group 2 (mean age 58 +/- 8 years). Left atrial diameters and left ventricular ejection fraction were measured by using transthoracic echocardiography. Left atrial appendage emptying and LAA filling velocity were measured by transesophageal Doppler echocardiography. Systolic appendage tissue velocities (SaV cm/s) were measured at the basal, mid, and tip of medial wall of LAA by transesophageal CDTI. Group 1 had significantly decreased LAA emptying velocities, mid SaVs, and left ventricular ejection fractions compared to group 2 (37 +/- 9 cm/s vs 55 +/- 22 cm/s, 3.1 +/- 1.6 cm/s vs 3.7 +/- 1.2 cm/s, and 47 +/- 13% vs 58 +/- 10%, respectively, P = 0.002, P = 0.04, P = 0.03). Group 1 had significantly increased left atrial diameters compared to group 2 (40 +/- 5 mm vs 36 +/- 6 mm P = 0.001). Left atrial appendage-filling velocities, basal SaVs and tip SaVs in group 1 were lower than those in group 2 but not significantly. CONCLUSIONS Mid-SaV of LAA medial wall and LAA emptying velocity decrease in patients with thrombus and/or SEC were an indication of functional disorder of LAA. Color Doppler tissue imaging appears to be a clinically applicable and reliable imaging technique that allows quantitative assessment of regional LAA systolic function.

Abstract
Mitral stenotic patients with left atrial spontaneous echo contrast (LA SEC) are associated with high risk of thromboembolism. The aim of this study was to predict thromboembolic risk in mitral stenotic patients. Femoral artery signal intensity alteration (%) was compared among the groups. Group 1 had severe mitral stenosis with LA SEC and group 2 slight mitral stenosis without LA SEC. Group 3 patients had normal transthoracic echocardiography. Femoral artery longitudinal view was studied with a linear USG probe (7.5 MHz, HP 2500). The femoral cuff was inflated to 300 mmHg, 7-12 cm below the inguinal ligament. Cuff inflation resulted in femoral arterial blood stasis. Intraluminal signal intensity increased in seconds. The femoral signal intensity alteration (%) at 180 seconds was compared to baseline. After femoral cuff inflation, femoral signal intensity alteration (%) was significantly higher in group 1 than groups 2 and 3 (P < 0.001). Group 1 patients had higher thromboembolic risk on the basis of their echocardiographic, clinical, and laboratory parameters. Increased signal intensity alteration (%) can be detected in the femoral artery in mitral stenotic patients with LA SEC.

Abstract
OBJECTIVES To review the available information on the action of hormones on the mechanisms involved in thrombotic risk. RESULTS AND CONCLUSIONS Thrombosis plays a crucial role in the genesis and progression of both coronary heart disease (CHD) and venous thromboembolic disease (VTED), the two main forms of cardiovascular disease. Two main determinants of the thromboembolic phenotype, hypercoagulable state and altered endothelium, accumulate much of the work performed on the influence of hormones on thrombosis. Information has accumulated mainly for oestrogens, but increasing evidences support a role for progestogens. The sensitivity of each of the three components of the hemostatic balance, the coagulation cascade, the anticoagulant system and fibrinolysis, to oestrogens has been widely examined in the literature. Functional tests suggest that HRT is accompanied by a procoagulant state. Much of the work has concentrated on changes induced on reputable indicators of risk for either CHD or VTED. Distinct indicators of increased coagulability, such as resistance to activated C protein, antithrombin or tissue factor pathway inhibitor have been selected for VTED, whereas factor VII, fibrinogen, and defective fibrinolysis, for CHD. Different states of genetic susceptibility have been involved in both forms of the disease. The status of health of endothelium, defines another scenario for attention in CHD. A long-term anti-atherogenic action of oestrogens, which may be associated with short-term risk in cases of atherosclerosis-induced endothelial dysfunction, may most adequately explain much of the clinical observation. In both CHD and VTED, the procoagulant changes initiate soon after HRT administration.
