　概要を見る

Recent epidemiological studies have demonstrated that coffee drinking is associated with reduced mortality of cardiovascular disease. However, its precise mechanisms remain to be clarified. In this study, we examined whether single ingestion of caffeine contained in a cup of coffee improves microvascular function in healthy subjects. A double-blind, placebo-controlled, crossover study was performed in 27 healthy volunteers. A cup of either caffeinated or decaffeinated coffee was drunk by the subjects, and reactive hyperemia of finger blood flow was assessed by laser Doppler flowmetry. In an interval of more than 2 days, the same experimental protocol was repeated with another coffee in a crossover manner. Caffeinated coffee intake slightly but significantly elevated blood pressure and decreased finger blood flow as compared with decaffeinated coffee intake. There was no significant difference in heart rate between caffeinated and decaffeinated coffee intake. Importantly, caffeinated coffee intake significantly enhanced post-occlusive reactive hyperemia of finger blood flow, an index of microvascular endothelial function, compared with decaffeinated coffee intake. These results provide the first evidence that caffeine contained in a cup of coffee enhances microvascular function in healthy individuals. (C) 2015 Japanese Pharmacological Society.

　概要を見る

Visceral fat accumulation contributes to the development of insulin resistance, leading to metabolic syndrome. Adiponectin provides a link between visceral fat accumulation and insulin resistance. In addition to environmental factors, genetic factors play important roles in visceral fat accumulation and circulating adiponectin levels. Genome-wide association studies (GWASs) have identified genetic variations in the adiponectin, C1Q and collagen domain containing (<i>ADIPOQ</i>) gene that are associated with adiponectin levels. In this study, we investigated whether <i>ADIPOQ</i> single nucleotide polymorphisms (SNPs) were associated with visceral fat accumulation and insulin resistance. We measured the visceral fat area (VFA) by computed tomography (CT) and examined the presence of the insulin resistance-related phenotype (fasting plasma glucose, fasting insulin, and homeostasis model assessment-insulin resistance [HOMA-IR]) in a set of Japanese individuals (731 men and 864 women) who were genotyped for seven <i>ADIPOQ</i> SNPs reported by recent GWASs (namely, rs6810075, rs10937273, rs1648707, rs864265, rs182052, rs17366568, and rs6773957). SNPs associated with the phenotype (<i>P</i> < 0.05) were then evaluated by association analysis using a second set of the study participants (383 men and 510 women). None of the SNPs was associated with body mass index (BMI) or VFA in men or women. However, the adiponectin-decreasing alleles of rs10937273 and rs1648707 were significantly associated with HOMA-IR (<i>P</i> = 0.0030 and <i>P</i> = 0.00074, respectively) in women, independently of BMI. These SNPs were significantly associated with decreased adiponectin levels in women. Our results suggested that rs10937273 and rs1648707 may affect insulin sensitivity by regulating adiponectin production by adipose tissue in women.

Adult T-cell leukemia/lymphoma (ATL) sometimes causes opportunistic infections. A 53-year-old woman with systemic lymphadenopathies was diagnosed with ATL by inguinal lymph node biopsies and underwent oral chemotherapy. Two months later, high grade fever, lower abdominal pain and lymphadenopathy recurred. Computed tomography revealed the presence of lymphadenopathy with marked gas formation in the pelvic lesion. Blood cultures were suggestive of septic lymphadenitis by <i>Bacteroides fragilis</i> (<i>BF</i>). This represents the first demonstration of giant lymphadenitis with gas formation caused by <i>BF</i> in a patient with ATL. Notably, septic lymphadenitis is pivotal in the differential diagnosis of systemic lymphadenopathy in ATL.<br>

患者は 24 歳，女性。発熱と体幹，四肢に多発する紅斑や関節痛があり，病初期には自己免疫疾患との鑑別に苦慮していた。経過中に著明な両眼瞼腫脹を生じ，皮膚筋炎や原発性皮膚リンパ腫を疑った。ゴットロン徴候や爪囲紅斑，筋関連酵素の上昇はなく，再検した病理組織で，脂肪細胞を取り囲んで浸潤する異型細胞を認め，いわゆる rimming 像を呈していた。免疫染色で異型細胞は CD3，CD8，T cell restricted intercellular antigen (TIA-1) が 陽 性であり，CD4，CD30，CD56，EBV-encoded small RNA (EBER)は陰性であった。また異型細胞は T 細胞受容体 <i>αβ</i> 鎖が陽性で，<i>γδ</i> 鎖は陰性だった。以上の結果から，皮下脂肪織炎様 T 細胞リンパ腫(subcutaneous panniculitis-like T-cell lymphoma ; SPTCL)と診断した。自験例は血球貪食症候群も合併していたため，治療は多剤併用化学療法を開始した。その結果，病変は消失し，治療終了後2年間再発はない。眼瞼腫脹を生じた SPTCL の報告は少なく，眼瞼腫脹はSPTCL では稀な皮膚症状と思われる。一方，眼窩悪性リンパ腫の半数が眼瞼腫脹を初発症状とし，自験例のように眼瞼腫脹を契機に診断された眼窩悪性リンパ腫の報告もあるため，眼瞼腫脹の鑑別に悪性リンパ腫も念頭におくべきであると考えた。

　概要を見る

Aim: The prevalence of overweight and a change in atherosclerotic lipid profiles may be linked to region-specific differences in atherosclerotic diseases. We evaluated whether the lipid phenotype could be linked to region-and sex-specific differences in the degree of atherosclerosis. Methods: Non-diabetic subjects included Okinawa (n=1674) and Nagano (n=1392) residents aged 30-75 years who underwent carotid ultrasonography for the measurement of maximum intima-media thickness (max IMT). Results: Average max IMT was higher in Okinawa men and women, and the increase in max IMT with age was enhanced in men. Multiple regression analysis showed that in addition to age and systolic blood pressure, low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol were IMT determinants only in men for both Okinawa and Nagano. Meanwhile, HDL-cholesterol was a determinant for Okinawa men and women, but not for Nagano men and women. Conclusions: This is the first report to show region-and sex-specific differences in the determinants for max IMT in a Japanese population. The evaluation of the relationship between lipid profile patterns and region-and sex-specific differences in carotid atherosclerosis burden may be required.

　概要を見る

<b><i>Background:</i></b>Patients with type 2 diabetes mellitus (T2DM) show a greater risk for coronary artery disease (CAD), but the risk stratification in asymptomatic CAD patients has not been established. This study investigated the prevalence and severity for asymptomatic CAD and predictors in T2DM patients.<b><i>Methods and Results:</i></b>In a multiclinic group, diabetic patients (320 men, 186 women) without known symptoms suggestive of CAD were recruited for multidetector computed tomography (MDCT). Patients were categorized according to severity of coronary atherosclerosis: Grade 1 (normal findings), Grade 2 (mild atherosclerosis without significant stenosis), Grade 3 (moderate stenosis/atherosclerosis, 50–74% stenosis), Grade 4 (moderate stenosis/atherosclerosis, 75–89% stenosis), Grade 5 (severe stenosis/atherosclerosis, ≥90% stenosis). The trend for severity grade of CAD was slightly higher in men than women (P=0.054). For critical lesions (combined Grades 3–5), the prevalence was almost equal (men 44% vs. women 37%; P=0.113). Multivariate models showed that in men, HbA_1c≥7.4%, dyslipidemia, duration of diabetes, retinopathy, and other type of cardiovascular diseases were predictors of critical lesions and in women, duration of diabetes and retinopathy were predictors.<b><i>Conclusions:</i></b>The prevalence and severity of asymptomatic CAD are comparably high in men and women with T2DM. Risk stratification by using MDCT might be useful to predict asymptomatic coronary lesions requiring coronary revascularization. (<i>Circ J</i> 2015; <b>79:</b> 2422–2429)
