　概要を見る

Immunoglobulin A vasculitis (IgAV), formerly known as Henoch-Schönlein purpura, primarily occurs during childhood between the ages of 3 and 15 years and is the most common form of systemic vasculitis in children ; its occurrence in adults has been rarely reported. Such low incidence could be attributable to either under-diagnosis or misdiagnosis. Thus, not only pediatricians but also physicians should be able to diagnose IgAV accurately to manage the patients appropriately and avoid its associated complications. In addition, treatment of adult onset IgAV with renal involvement has not been fully established yet. We describe here a case of adult onset IgAV complicated by proteinuria and pharyngitis, which was cured by no specific treatment. J. Med. Invest. 66 : 344-346, August, 2019.

Primary non-Hodgkin bone lymphoma (PBL) can involve solitary or multiple destructive bone lesions such as those of the femur or pelvis humerus, and some cases have osteolytic lesions. PBL is a rare disease in adults. Thus, PBL is rarely considered a differential diagnosis of the osteolytic tumor. In addition, PBL can be underdiagnosed because patients do not experience symptoms or show objective abnormalities in the early stage. Here, we reported an elderly patient with PBL in multiple bones, including the cranial and femoral bones that were fractured due to falling. J. Med. Invest. 66 : 347-350, August, 2019.

The culprit lesion of acute myocardial infarction could be predicted by electrocardiogram findings. However, we experienced some cases with coronary angiographic finding in the area of ST-T elevation that was different from that predicted. The lambda-like J wave could be caused by ischemia although the mechanism has not been fully elucidated. We report a case of acute myocardial infarction that showed discrepancy between ST-T elevation with lambda-like ischemic J wave in a broad area and coronary angiographical finding of diagonal branch occlusion.

　概要を見る

Middle-aged marathon runners have an increased risk of developing atrial fibrillation (AF). A previous study described that repetitive marathon running was associated with left atrial (LA) dysfunction. However, whether this change is common in marathon runners and which runners are at risk of LA dysfunction remain unknown. The purpose of this study was to determine which factors could predict LA dysfunction. We prospectively examined 12 healthy amateur volunteers (9 males, 31 ± 8 years old) who participated in a full marathon. All echocardiographic measurements and speckle-tracking echocardiography were performed before and after the marathon. The endpoint was defined as reduced LA reservoir strain 1 day after the marathon (non-responder group). Seven participants were in the non-responder group. Age (35 ± 9 vs. 26 ± 2 years, p = 0.020), augmentation index (76 ± 12 vs. 55 ± 8, p = 0.002), and diastolic blood pressures (83 ± 11 vs. 70 ± 7 mmHg, p = 0.021) in the non-responder group were significantly higher compared with the responder group. In multivariate linear regression analysis, only the augmentation index was an independent predictor of reduced LA reservoir function after the marathon (β = - 0.646, p = 0.023). The augmentation index was a predictive marker for reduction in LA reservoir function after a marathon in healthy amateur volunteers.

Background: Peripheral artery disease causes significant functional disability and results in impaired quality of life. Ischemic tissue injury releases various endogenous ligands for Toll-like receptors (TLRs), suggesting the involvement of TLRs in blood flow recovery. However, the role of TLR9, which was originally known as a sensor for bacterial DNA, remains unknown. This study investigated the role of TLR9 in blood flow recovery in the ischemic limb using a mouse hind-limb ischemia model. Methods and Results: Unilateral femoral artery ligation was performed in TLR9-deficient (Tlr9 -/-) mice and wild-type mice. In wild-type mice, femoral artery ligation significantly increased mRNA expression of TLR9 in the ischemic limb (P < 0.001) and plasma levels of cell-free DNA (cfDNA) as determined by single-stranded DNA (ssDNA) (P < 0.05) and double-stranded DNA (dsDNA) (P < 0.01), which are endogenous ligands for TLR9, compared with the sham-operated group. Laser Doppler perfusion imaging demonstrated significantly improved ratio of blood flow in the ischemic to non-ischemic limb in Tlr9 -/- mice compared with wild-type mice at 2 weeks after ligation (P < 0.05). Tlr9 -/- mice showed increased capillary density and reduced macrophage infiltration in ischemic limb. Genetic deletion of TLR9 reduced the expression of TNF-α, and attenuated NF-κB activation in ischemic muscle compared with wild-type mice (P < 0.05, respectively) at 3 days after the surgery. ODN1826, a synthetic agonistic oligonucleotide for TLR9, or plasma obtained from mice with ischemic muscle promoted the expression of TNF-α in wild-type macrophages (P < 0.05), but not in Tlr9 -/- macrophages. ODN1826 also activated NF-κB signaling as determined by the degradation of IκBα in wild-type macrophages (P < 0.05), but not in Tlr9 -/- macrophages. In vitro experiments using human umbilical vein endothelial cells demonstrated that TNF-α, or conditioned medium obtained from wild-type macrophages treated with ODN1826 accelerated cell death as determined by MTS assay (P < 0.05 and P < 0.01, respectively). Conclusion: Our results suggest that ischemic muscle releases cfDNA, which activates TLR9 and enhances inflammation, leading to impairment of blood flow recovery in the ischemic limb. cfDNA-TLR9 signaling may serve as a potential therapeutic target in ischemic limb disease.

BACKGROUND: The coagulation system is closely linked with vascular inflammation, although the underlying mechanisms are still obscure. Recent studies show that protease-activated receptor (PAR)-2, a major receptor of activated factor X, is expressed in both vascular cells and leukocytes, suggesting that PAR-2 may contribute to the pathogenesis of inflammatory diseases. Here we investigated the role of PAR-2 in vascular inflammation and atherogenesis. METHODS: We generated apolipoprotein E-deficient ( ApoE-/-) mice lacking systemic PAR-2 expression ( PAR-2-/- ApoE-/-). ApoE-/- mice, which lack or express PAR-2 only in bone marrow (BM) cells, were also generated by BM transplantation. Atherosclerotic lesions were investigated after 20 weeks on a Western-type diet by histological analyses, quantitative reverse transcription polymerase chain reaction, and Western blotting. In vitro experiments using BM-derived macrophages were performed to confirm the proinflammatory roles of PAR-2. The association between plasma activated factor X level and the severity of coronary atherosclerosis was also examined in humans who underwent coronary intervention. RESULTS: PAR-2-/- ApoE-/- mice showed reduced atherosclerotic lesions in the aortic arch ( P<0.05) along with features of stabilized atherosclerotic plaques, such as less lipid deposition ( P<0.05), collagen loss ( P<0.01), macrophage accumulation ( P<0.05), and inflammatory molecule expression ( P<0.05) compared with ApoE-/- mice. Systemic PAR2 deletion in ApoE-/-mice significantly decreased the expression of inflammatory molecules in the aorta. The results of BM transplantation experiments demonstrated that PAR-2 in hematopoietic cells contributed to atherogenesis in ApoE-/- mice. PAR-2 deletion did not alter metabolic parameters. In vitro experiments demonstrated that activated factor X or a specific peptide agonist of PAR-2 significantly increased the expression of inflammatory molecules and lipid uptake in BM-derived macrophages from wild-type mice compared with those from PAR-2-deficient mice. Activation of nuclear factor-κB signaling was involved in PAR-2-associated vascular inflammation and macrophage activation. In humans who underwent coronary intervention, plasma activated factor X level independently correlated with the severity of coronary atherosclerosis as determined by Gensini score ( P<0.05) and plaque volume ( P<0.01). CONCLUSIONS: PAR-2 signaling activates macrophages and promotes vascular inflammation, increasing atherosclerosis in ApoE-/- mice. This signaling pathway may also participate in atherogenesis in humans.

BACKGROUND: It has been recognized that a comprehensive cardiac rehabilitation (CR) program improves mortality in patients with chronic heart failure. On the other hand, the magnitude of the improvement in exercise capacity after CR differs among individuals. The aim of this study was to assess the echocardiographic determinants of responders to CR using preload stress echocardiography. METHODS: We prospectively enrolled 58 chronic heart failure patients with reduced left ventricular ejection fraction (aged 62 ± 11 years; 69% male; left ventricular ejection fraction 43% ± 7%) who had received optimized medical treatment in a CR program for 5 months. We performed preload echocardiographic studies using leg positive pressure (LPP) to assess the echocardiographic parameters during preload augmentation. We defined 41 patients as a development cohort to assess the predictive value of echocardiographic variables. Next, we validated results in the remaining 17 patients as a validation cohort. RESULTS: In the development cohort, significant improvement in peak oxygen uptake (VO2) (>10%) after CR was observed in 58% patients. In a multivariable logistic regression model, the significant predictor of improvement in exercise capacity was right ventricular (RV) strain during LPP (odds ratio: 3.96 per 1 standard deviation; P = 0.01). An RV strain value of -16% during LPP had a good sensitivity of 0.79 and a specificity of 0.71 to identify patients with improvement in peak VO2. In the validation cohort, an optimal cutoff value of RV strain value was the same (area under the curve: 0.77, sensitivity: 0.78, specificity: 0.65). CONCLUSIONS: RV strain during LPP may be an echocardiographic parameter for assessing beneficial effects of CR.
