Analysis of Renal Artery Stenosis in Patients with Heart Failure: A RASHEF Study

Background:

Previous data are controversial about the association of renal artery stenosis (RAS) with clinical outcome in patients with heart failure. Definition of RAS in previous studies might not be appropriate. By definition of RAS with renal duplex sonography, we investigated the association of RAS with clinical outcome in patients with heart failure.

Methods:

In this retrospective study, we identified 164 patients with heart failure (New York Heart Association classification ≥II; left ventricular ejection fraction <50%) who had received renal duplex sonography during hospital stay. RAS was defined as renal-aortic ratio ≥3.5 or a peak systolic velocity ≥200 cm/s (or both), or occlusion of the renal artery. Categorical data of patients were compared using the Chi-square test or Fisher''s exact test. Cox proportional hazards regression modeling technique was used to investigate the prognostic significance of possible predictors.

Results:

Finally, 143 patients were enrolled. Median follow-up time was 32 months (1–53 months). Twenty-two patients were diagnosed as RAS by renal duplex sonography, including 13 unilateral RAS (3 left RAS, 10 right RAS) and 9 bilateral RAS. There were more all-cause mortality and cardiovascular death in patients with RAS than patients without RAS. By multivariate analysis, RAS was a significant predictor for all-cause death and cardiovascular death (hazard ratio [HR] = 4.155, 95% confidence interval [CI]: 1.546–11.164, P = 0.005; and HR = 3.483, 95% CI: 1.200–10.104, P = 0.022, respectively). As for composite endpoint events, including death, nonfatal myocardial infarction, ischemic stroke or intracranial hemorrhage, rehospitalization for cardiac failure, and renal replacement therapy, only angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker was significant predictor. RAS was not a significant predictor for composite endpoint events.

Conclusions:

Our data suggested that RAS is associated with a poorer clinical outcome in patients with heart failure.

Erectile dysfunction in patients with liver disease related to chronic hepatitis B

Background/Aims

Despite sexual function making an important contribution to the quality of life, data on erectile function are relatively scant in patients with chronic liver disease. We evaluated the prevalence of and risk factors for erectile dysfunction (ED) in patients with liver disease related to hepatitis B, especially among those with chronic hepatitis B (CHB) or early-stage cirrhosis.

Methods

In total, 69 patients (35 with CHB and 34 with hepatitis-B-related liver cirrhosis [HBV-LC]) aged 40-59 years were analyzed. Child-Pugh classes of A and B were present in 30 (88.2%) and 4 (11.8%) of the patients with HBV-LC, respectively. The erectile function of the patients was evaluated using the Korean version of IIEF-5.

Results

The prevalence of any ED was 24.6% for all patients, and 8.6% and 41.2% for those with CHB and HBV-LC, respectively (P=0.002). While there was only one (2.9%) CHB patient for each stage of ED, mild, moderate, and severe ED stages were seen in three (8.8%), one (2.9%), and ten (29.4%) of the HBV-LC patients, respectively. Multiple regression analysis identified the type of liver disease (P=0.010), hypertension (P=0.022), score on the Beck Depression Inventory (P =0.044), and the serum albumin level (P=0.014) as significant independent factors for the presence of ED.

Conclusions

The prevalence of ED was significantly higher in patients with early-stage HBV-LC than in those with CHB. Therefore, screening male patients with early viral cirrhosis for ED and providing appropriate support are needed, especially when the cirrhosis is accompanied by hypertension, depression, or a depressed level of serum albumin.     

彩色多普勒超声测量背深静脉在诊断阴茎静脉性勃起功能障碍中的作用

目的 评估彩色多普勒超声测量阴茎背深静脉在对静脉性勃起功能障碍(ED)诊断中的价值.方法 回顾应用彩色多普勒超声及阴茎海绵体造影检查70例临床疑似静脉性ED患者注射药物后的阴茎勃起情况,按不同的CDUS检查方法将本组患者分为两组:未测背深静脉诊断静脉性ED组和测量背深静脉诊断静脉性ED组,并与CG结果进行比较.结果 CDUS未测量背深静脉诊断为静脉性ED灵敏度为45.46％,特异度为100％,与CG之间一致性较差(Kappa=0.382),测量背深静脉后诊断为静脉性ED灵敏度为100％,特异度为76.92％,与CG之间一致性较好(Kappa=0.807).结论 CDUS测量背深静脉在诊断静脉性ED中起到重要的作用.     

子痫前期发病机制的研究进展

子痫前期是妊娠特有的疾病,由于该病对母儿的危害极大,其发病机制一直是产科研究的焦点。随着研究的不断深入,目前认为该病主要与遗传、血管内皮受损、免疫失衡及炎症反应等因素相关,其中遗传因素是内因,血管内皮损伤因子水平异常升高、血管内皮保护因子水平降低是该病发生、发展的关键环节,而免疫失衡及炎症反应进一步加重血管内皮的损伤,多种机制相互作用导致子痫前期的发生。

Does the etiology affect the outcome and satisfaction rates of penile prosthesis implantation surgery?

Our aim was to compare the outcomes and satisfaction rates of men undergoing penile prostheses implantation (PPI) secondary to radical prostatectomy (RP) and other causes of vasculogenic erectile dysfunction (ED). A total of 142 patients, of whom 60 underwent PPI due to ED following RP (Group 1) and 82 underwent PPI due to ED with other vasculogenic causes (Group 2) were included in this study. The preoperative erectile status was evaluated with the International Index of Erectile Function (IIEF). The satisfaction of patients and partners were evaluated by a telephone interview using Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire and Erectile Dysfunction Inventory of Treatment Satisfaction Partner Survey. Preoperative mean IIEF scores were significantly lower in Group 1 (17.5 ± 6.4 vs. 24.2 ± 5.1, p = 0.01). For Groups 1 and 2, the mean EDITS scores of the patients were 58 ± 10 and 71 ± 8, respectively, and that for the partners were 46 ± 8 and 65 ± 7, respectively. Group 1 had significantly lower scores both for the EDITS and the EDITS Partner Survey (p = 0.03, p = 0.01, respectively). Patients who had undergone RP and their partners were found to have lower satisfaction rates compared to patients with other causes of vasculogenic ED who had penile implant surgery. From this point of view, it is important to know the patient's expectations about the treatment outcomes and a preoperative psychological and sexual counseling should be managed for possible treatment alternatives after RP.
