Clinical, laboratory, and echocardiographic data were retrospectively analyzed in 112 patients with acute Kawasaki disease who received high-dose (2 g/kg) intravenous gamma-globulin (IVIG) treatment within 2 days and were compared for those who were responsive and non-responsive to initial IVIG treatment. Coronary arteries adjusted for body surface area (BSA) were evaluated quantitatively by comparison with the mean dimensions for 85 normal control subjects. The incidence of coronary abnormalities was higher in IVIG-non-responsive patients as compared to IVIG-responsive patients (71% versus 5%, p<0.0001). Univariate analysis of pre-IVIG data showed that the neutrophil count and serum levels of C-reactive protein (CRP), total bilirubin (TB), aspartate aminotransferase (AST), alanine aminotransferase, and lactate dehydrogenase (LDH) were significantly higher in IVIG-non-responsive versus responsive patients. Multivariate analysis selected CRP (p=0.009), TB (p<0.001), and AST (p=0.002) as independent predictors of non-responsiveness to initial IVIG treatment. By defining predictive values, patients with at least two of three predictors (CRP>or=7.0 mg, TB>or=0.9 mg, or AST>or=200 IU/L) are considered to be non-responsive to IVIG for acute Kawasaki disease. Alternatively, more intense initial therapy may be a promising therapeutic strategy for patients who are predicted to be IVIG-non-responsive.

The increased consumption of fruits and vegetables is associated with reduced cardiovascular disease. The molecular basis of this health effect is not fully understood, yet dietary flavonoids are thought to play an important role. Genetic engineering has enabled us to overexpress specific flavonoids (flavones and flavonols) in tomato fruit. Human C-reactive protein transgenic (CRPtg) mice express markers of cardiovascular risk that allow us to study of the putative health effects of wild-type tomato (wtTom) and flavonoid-enriched tomato (flTom). In this study, we analyzed whether consumption of wtTom, at a dose achievable with a human diet, has beneficial effects on cardiovascular risk markers and whether flTom may enhance such effects. CRPtg mice were fed a diet containing 4 g/kg wtTom, flTom peel, vehicle, or 1 g/kg fenofibrate, which reportedly reduces cardiovascular risk, for 7 wk. Markers of general health (bodyweight, food intake, and plasma alanine aminotransferase activities) and of cardiovascular risk (plasma CRP, fibrinogen, E-selectin, and cholesterol levels) were analyzed. All groups had comparable food intakes and body-weight gains. Plasma alanine aminotransferase activities increased significantly in vehicle and fenofibrate-treated mice. Compared with baseline, wtTom and flTom significantly reduced basal human CRP concentrations by 43 and 56%, respectively. The CRP-lowering effect of flTom significantly exceeded that of wtTom. The effects of flTom on CRP were reversed within a 2-wk washout period. WtTom and flTom did not affect fibrinogen, but comparably repressed E-selectin expression and upregulated HDL cholesterol. Tomato peel consumption improved cardiovascular risk factors in CRPtg mice, a beneficial effect that was further enhanced by enrichment of the flavonoid content.

Clinical characteristics to predict the development of coronary artery abnormalities (CAA) in Kawasaki disease (KD) were assessed by reviewing medical records of patients diagnosed with KD at Korea University Medical Center from March 2001 to February 2005. Of the 285 patients diagnosed with KD, 19 developed CAA (6.7%). Compared with the CAA(-) group, the CAA(+) group had a longer duration of fever after intravenous gamma-globulin (IVGG) injection (2.4+/-2.9 vs. 1.5+/-1.2 days, p=0.008) and higher C-reactive protein (CRP)(12.3+/-7.8 vs. 8.7+/-7.1 mg/dL, p=0.038). In particular, the CAA(+) group tended to have more than 7 days of fever before IVGG and more than 3 days of fever after IVGG (26.3 vs. 5.3%, p<0.001; 26.3 vs. 6.4%, p=0.002). When the IVGG responsiveness was defined by the presence of defervescence within 3 days after IVGG, IVGG-non-responders showed a higher incidence of CAA (22.7 vs. 5.3%, p=0.002). Non-responders had a longer duration of fever after IVGG (5.5+/-1.9 vs. 1.2+/-0.6 days, p<0.001) and a significantly increased CRP, AST, ALT and total bilirubin. Multivariate regression analysis for CAA showed that the only factor significantly associated with the development of CAA was total fever that lasted for longer than 8 days (OR=4.052, 95% CI=1.151-14.263, p=0.0293). Conclusively, the most important predictor of CAA in KD is total duration of fever longer than 8 days. Early identification of IVGG non-responders and active therapeutic intervention for fever in KD cases might decrease the incidence of CAA.

In a randomized, placebo-controlled study, we studied the effects of 4 months' treatment with rosiglitazone on low-grade inflammation, liver function, lipid levels, and blood pressure in 30 overweight women with polycystic ovary syndrome. Rosiglitazone significantly decreased serum C-reactive protein levels, white blood cell count, and alanine aminotransferase enzyme activity but did not affect lipid or blood pressure levels. Placebo had no effect on any parameters.

The present study investigated the expression pattern of apolipoprotein M (apoM) mRNA in a rat model of hepatic ischemia-reperfusion injury (IRI). Animals were ischemic for 1 hour followed by various reperfusion times. As expected, serum alanine aminotransferase levels were significantly increased under IRI, which indicated the severity of liver injury. Hepatic mRNA levels of HSP70, which is the most common characterized protein within the family of heat-shock proteins (HSP), were significantly increased after 0.5 to 3 hours of IRI. Plasma C-reactive protein, high-density lipoprotein-cholesterol, and lipoprotein (a) levels were significantly increased after 1-hour ischemia followed by 0.5 to 3 hours of reperfusion. Interestingly, similar to HSP70, apoM mRNA levels in the liver were gradually increased after 0.5 to 3 hours of IRI, whereas it returned to a lower level after 6 or 24 hours of IRI, which indicated that hepatic apoM expression was significantly influenced by the acute phase of IRI. However, plasma apoM levels were not increased in parallel, even slightly decreasing after 0.5 or 1 hour of IRI. We concluded that apoM mRNA expression pattern, like HSP70, in the liver showed rapid, significant changes during hepatic local IRI.

Nonalcoholic fatty liver disease (NAFLD) has been associated with metabolic disorders, including central obesity, dyslipidema, hypertension, and hyperglycemia. Metabolic syndrome, obesity, and insulin resistance are major risk factors in the pathogenesis of NAFLD. The aim of this study was to identify the relative contribution of the metabolic syndrome, obesity, and insulin resistance to alanine aminotransferase (ALT) activity in NAFLD. A total of 3091 subjects diagnosed with fatty liver by ultrasonography were enrolled. All components of metabolic syndrome criteria, anthropometric parameters, fasting insulin levels, high-sensitivity C-reactive protein (hs-CRP) as an inflammation marker, and ALT were measured in each subject. Homeostasis model assessment--insulin resistance (HOMA-IR) as a measure of insulin resistance and body mass index (BMI) as a measure of obesity were calculated. The prevalence of increased ALT levels (>40 IU/L) was 26.7%. Increased ALT activity was significantly associated with the following characteristics: male sex, young age, increased triglycerides, fasting glucose, fasting insulin, HOMA-IR, hs-CRP, waist circumference, BMI and diastolic blood pressure, and decreased high-density lipoprotein cholesterol (HDL-C). According to the increase in the number of metabolic syndrome components, BMI, HOMA-IR, and hs-CRP, the prevalence and odds ratio for having increased ALT activity were significantly increased. Central obesity, raised triglycerides, reduced HDL-C, and raised fasting glucose were strongly associated with increased ALT activity. In conclusion, a number of metabolic syndrome components, obesity, insulin resistance, and hs-CRP, are strong predictors of increased ALT activity in NAFLD. Central obesity, raised triglycerides, reduced HDL-C, and raised fasting glucose are metabolic syndrome components that contributed to increased ALT activity.

Ultra-marathon running is frequently associated with muscle fibre damage. However, ultra-marathon related information is scarce. The present study evaluated muscle and cartilage biomarkers, and cytokine secretion during a 200 km running event. Venous blood samples from 54 trained male ultra-marathon runners (mean +/- SD, 45.7 +/- 5.1 years). Plasma creatine phosphokinase (CPK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate, glucose, high-sensitivity C-reactive protein (Hs-CRP), interleukin-6 (IL-6), TNF- proportional, variant and serum cartilage oligomeric matrix protein (COMP) content were determined before, midway and immediately after the race. CPK increased 90-fold (19-fold at 100 km) from pre-race value and LDH increased 3.7-fold (2.2-fold at 100 km). AST increased 15-fold (5-fold at 100 km) and ALT increased 3.9-fold (2-fold at 100 km). Blood lactate and glucose levels did not change significantly. Hs-CRP increased 23-fold (3-fold at 100 km) and IL-6 increased 121-fold at 100 km, and then remained stable up to 200 km, whereas TNF- proportional, variant did not change significantly. Serum COMP increased 3-fold (1.3-fold at 100 km). Post-run CPK was correlated with LDH (r = 0.62, P < 0.001), Hs-CRP (r = 0.45, P < 0.001), ALT (r = 0.89, P < 0.001), AST (r = 0.97, P < 0.001), and IL-6 (r = 0.61, P < 0.001). The present study demonstrated that blood biomarkers related to muscle and cartilage damage and inflammation were increased during a 200 km run and that this was particularly marked during the second half of the event. Ultra-marathon running clearly has a major impact on muscle and cartilage structures.

We present a case of a cat-scratch disease (CSD) presenting with typical (primary lesion and regional lymphadenitis) and rare (purulent lymphadenitis and maculopapular rash) symptoms and positive epidemiological data. Laboratory blood test showed normal values for routine parameters, except for mild leukocytosis (L 12.4 x 10(9)), elevated erythrocyte sedimentation rate (SE 65/h) and moderately elevated asparta e-aminotransferase and alanine-aminotransferase values (AST/ALT 48/90), fibrinogen (5.3 g/L) and C-reactive protein (CRP 85 mg/L). Cytological analysis of lymph node content revealed granulomatous inflammation in the first sample, and purulent inflammation in the second sample. In paired serum samples, collected on the 15th and 29th day from the onset of disease, antibodies IgG (titre 4096/8192) and IgM (titre 80/40) to Bartonella henselae were detected by using an indirect immunofluorescence assay (IFA). Antibiotic therapy with azithromycin (1 x 500 mg per os/5 days) was administered. Purulent lymphadenitis and rash, although a rare clinical manifestation in CSD, are significant clinical findings in differentiating CSD from other febrile illnesses accompanied with rash and lymphadenitis.

To evaluate the potential dose effect of rosuvastatin on triglyceride (TG) levels in Japanese hypertriglyceridemic patients, we randomized 154 patients with TG levels of >or=200 and <800 mg/dL to 8 weeks of treatment with rosuvastatin 5, 10 or 20mg once daily; bezafibrate 200mg twice daily; or placebo. Compared with placebo, TG was reduced by 30.1% with rosuvastatin 5mg, 30.1% with 10mg and 32.3% with 20mg (all p<or=0.0001), with no evidence of a dose effect. Changes in TG were evident after 2 weeks of treatment and maintained thereafter. In a benchmark comparison, rosuvastatin across its dose range reduced TG by 29.1-31.1% from baseline versus 45.4% for bezafibrate. Compared with bezafibrate, rosuvastatin was superior with respect to changes in non-high-density lipoprotein cholesterol (non-HDL-C, -36.8 to -44.3% for rosuvastatin versus -2.0% for bezafibrate), low-density lipoprotein cholesterol (-31.9 to -41.0% versus +29.3%), total cholesterol (-27.1 to -33.3% versus +2.1%), although smaller improvements in HDL-C (12.4-16.7% versus 19.6%) were observed. Rosuvastatin also produced superior dose-related decreases in median high-sensitivity C-reactive protein (22.9-38.5%). Treatment was well tolerated in both rosuvastatin and bezafibrate patients, with clinically important increases in alanine aminotransferase being rare, no adverse effect on renal function being observed and no cases of myopathy or rhabdomyolysis being reported. The current study does not suggest a dose-related effect of rosuvastatin in lowering TG in hypertriglyceridemic Japanese patients, although dose-related improvements in other elements of the atherogenic lipid profile were observed.

Ischemia -modified albumin was regarded as an early marker of cardiac ischemia. On the other hand, it has been reported that increased ischemia-modified albumin levels are associated with unstable plaque processes like percutaneous coronary intervention, acute coronary syndrome or myocardial infarction. This prospective study aimed to investigate the role of ischemia-modified albumin in patients with peripheral vascular disease undergoing peripheral vascular intervention, a plaque-altering procedure without evidence of tissue ischemia. Peripheral vascular intervention was performed in 21 consecutive patients (68.2+/-13.3 years) with typical leg claudication and documented peripheral vascular disease. Additionally, 96 consecutive patients (66+/-12.0 years) undergoing routine exercise stress test for the exclusion of functionally relevant coronary artery disease were defined as controls. It was assumed that in the latter patients no unstable plaque-altering processes were present. Blood samples were drawn before, and 30 min and 3 h after, revascularization in the peripheral vascular intervention group, as well as before, and 30 min and 3 h after, maximum stress testing in the control group, respectively. Ischemia-modified albumin levels were analyzed using the albumin cobalt-binding test. In patients undergoing peripheral vascular intervention, ischemia-modified albumin increased from 116.6+/-19.1 U/ml at baseline to 132.0+/-19.3 U/ml 30 min after intervention (+14.4+/-15.7%, P<0.001) and decreased to 123.5+/-17.8 U/ml 3 h later (-5.7+/-10.5%, P<0.001 compared with postintervention, P<0.001 compared with baseline). The control group showed a slight but significant decrease in ischemia-modified albumin from 103.0+/-11.0 to 100.2+/-11.6 U/ml poststress (-2.2+/-11.5%, P<0.05) and returned close to baseline 3 h later (101.8+/-10.3 U/ml, +2.4+/-10.9%, P=NS, compared with poststress and with baseline). For both groups, ischemia-modified albumin showed no correlation with albumin (at baseline P=0.62) and total protein (P=0.67), but significant correlation with creatinine (P=0.04) and C-reactive protein (P=0.02). In addition, ischemia-modified albumin was independent of age, sex, alanine aminotransferase, aspartate aminotransferase, creatine kinase, creatine kinase-MB, cholesterol, and triglycerides. This study showed an increased basal ischemia-modified albumin level in patients with peripheral vascular disease undergoing peripheral vascular intervention. Ischemia-modified albumin levels transiently increased shortly after peripheral vascular intervention, indicating a strong correlation between serum concentration of ischemia-modified albumin and processes associated with acute plaque disruption/rupture.
