Background and aims

Heparin-binding EGF-like growth factor (HB-EGF) is a representative EGF family member that interacts with EGFR under diverse stress environment. Previously, we reported that the HB-EGF-targeting using antisense oligonucleotide (ASO) effectively suppressed an aortic aneurysm in the vessel wall and circulatory lipid levels. In this study, we further examined the effects of the HB-EGF ASO administration on the development of hyperlipidemia-associated atherosclerosis using an atherogenic mouse model.

Methods and results

The male and female LDLR deficient mice under Western diet containing 21% fat and 0.2% cholesterol content were cotreated with control and HB-EGF ASOs for 12 weeks. We observed that the HB-EGF ASO administration effectively downregulated circulatory VLDL- and LDL-associated lipid levels in circulation; concordantly, the HB-EGF targeting effectively suppressed the development of atherosclerosis in the aorta. An EGFR blocker BIBX1382 administration suppressed the hepatic TG secretion rate, suggesting a positive role of the HB-EGF signaling for the hepatic VLDL production. We newly observed that there was a significant improvement of the insulin sensitivity by the HB-EGF ASO administration in a mouse model under the Western diet as demonstrated by the improvement of the glucose and insulin tolerances.

Conclusion

The HB-EGF ASO administration effectively downregulated circulatory lipid levels by suppressing hepatic VLDL production rate, which leads to effective protection against atherosclerosis in the vascular wall.  相似文献

Rapid reversal of coagulopathy is recommended in warfarin-associated intracerebral hemorrhage (WAICH). However, rapid correction of the INR has not yet been proven to improve clinical outcomes, and the rate of correction with fresh-frozen plasma (FFP) can be variable. We sought to determine whether faster INR reversal with FFP is associated with decreased hematoma expansion and improved outcome. We performed a retrospective analysis of a prospectively collected cohort of consecutive patients with WAICH presenting to an urban tertiary care hospital from 2000 to 2013. Patients with baseline INR > 1.4 treated with FFP and vitamin K were included. The primary outcomes are occurrence of hematoma expansion, discharge modified Rankin Scale (mRS), and 30-day mortality. The association between timing of INR reversal, ICH expansion, and outcome was investigated with logistic regression analysis. 120 subjects met inclusion criteria (mean age 76.9, 57.5% males). Median presenting INR was 2.8 (IQR 2.3–3.4). Hematoma expansion is not associated with slower INR reversal [median time to INR reversal 9 (IQR 5–14) h vs. 10 (IQR 7–16) h, p = 0.61]. Patients with ultimately poor outcome received more rapid INR reversal than those with favorable outcome [9 (IQR 6–14) h vs. 12 (8–19) h, p = 0.064). We find no evidence of an association between faster INR reversal and either reduced hematoma expansion or better outcome.  相似文献

Objective Thyrotoxic hypokalaemic periodic paralysis (THPP) is an uncommon condition with intermittent episodes of muscle weakness and occasionally severe paralysis. THPP is a common complication of hyperthyroidism in Asian populations, and has also been reported in other ethnic groups including Caucasians. This study aimed to conduct an analysis of THPP in a Turkish population, and is to our knowledge the first analysis of a homogeneous Caucasian group. Subjects Forty cases with THPP were identified in the Turkish population. Three out of the 40 were new cases and were assigned as index cases. Two cases were not included in the analysis because of lack of data. Results THPP was diagnosed in 10 cases during the first attack and was observed to have a significant shorter complete recovery time statistically in this group (P < 0·01). The majority of cases were hypokalaemic, while there were two normokalaemic cases. Classification of the cases according to their potassium (K) levels revealed that the group with K levels < 2·5 mEq/l had a statistically longer amelioration time than the group with K levels ≥ 2·5 mEq/l. When the cases were classified according to intravenous or oral application of K, the mean amelioration time was 6·8 ± 3·6 h for the intravenous group and 13·1 ± 7·6 for the oral group. Mean complete recovery times of the groups were 29·4 ± 16·2 h and 52·8 ± 18·0 h, respectively. The intravenous group had a shorter amelioration time and complete recovery time, and both were statistically significant (P < 0·05 for each). Conclusions THPP may be seen among Caucasians. Diagnosing THPP during the first attack might decrease the recovery time. The level of hypokalaemia seems to affect the recovery time and initial low K levels may lead to more deterioration in a patient's health compared with mild or near‐normal levels. Intravenous, rather than oral, application of K may be advantageous for shortening both the amelioration and complete recovery times.  相似文献

ObjectiveThe aim of this study was to determine whether there is any association with anti-tumor necrosis factor (TNF) agent administration and development of new-onset inflammatory bowel disease (IBD) in ankylosing spondylitis (AS) patients.MethodsRecords of the patients who met 1984 modified New York criteria for AS between 1998 and 2016 at Rheumatology Department were evaluated retrospectively and data about the patients, IBD properties and medication were obtained.ResultsAmong 420 patients, 310 were male, the average age was 42.9 ± 1.3 years, average disease duration was 16.7 ± 10.4 years. Anti-TNF agents were in use by 154 patients, 52 patients were receiving etanercept (ETN), infliximab (INF), adalimumab (ADA), and golimumab (GO) treatments were ongoing in 50, 41, and 11 patients, respectively. New-onset IBD developed in 10 patients; 3 from the group treated with non-anti-TNF drugs (1.1%) and 7 from the group treated with anti-TNF agents (4.5%) (p = 0.042). No significant difference was detected between three anti-TNF agent forms in relation with the risk of IBD onset. In AS patients, existence of familial AS (OR 4.69 (95%CI 1.28-17.19, p = 0.020) and anti-TNF agent treatment (OR 4.17 (95%CI 1.06-16.38, p = 0.041) were independent risk factors for new-onset IBD development.ConclusionDespite the increased risk of new-onset IBD development during the course of AS, paradoxical response to anti-TNF drugs must also be considered as a source that triggers onset of IBD.  相似文献
