Sex differences in associations between creatinine and cystatin C-based kidney function measures with stroke and major bleeding. Eur Stroke J 2023; 8:756-768. [PMID: 37641551 PMCID: PMC10465308 DOI: 10.1177/23969873231173282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 04/14/2023] [Indexed: 08/31/2023] Open
Abstract
PURPOSE We sought to explore whether adding kidney function biomarkers based on creatinine (eGFRCr), cystatin C (eGFRCys) or a combination of the two (eGFRCr-Cys) could improve risk stratification for stroke and major bleeding, and whether there were sex differences in any additive value of kidney function biomarkers. METHOD We included participants from the UK Biobank who had not had a previous ischaemic or haemorrhagic stroke or major bleeding episode, and who had kidney function measures available at baseline. Cause-specific Cox proportional hazards models tested associations between eGFRCr, eGFRCys and eGFRCr-Cys (mL/min/1.73 m2) with ischaemic and haemorrhagic stroke, major bleeding (gastrointestinal or intracranial, including haemorrhagic stroke) and all-cause mortality. FINDINGS Among 452,879 eligible participants, 246,244 (54.4%) were women. Over 11.5 (IQR 10.8-12.2) years, there were 3706 ischaemic strokes, 795 haemorrhagic strokes, 26,025 major bleeding events and 28,851 deaths. eGFRCys was more strongly associated with ischaemic stroke than eGFRCr: an effect that was more pronounced in women (men - HR: 1.16, 95% CI: 1.12-1.19; female to male comparison - HR: 1.11, 95% CI: 1.05-1.16, per 10 mL/min/1.73 m2 decline in eGFRCys). This interaction effect was also demonstrated for eGFRCr-Cys, but not eGFRCr. eGFRCys and eGFRCr-Cys were more strongly associated with major bleeding and all-cause mortality than eGFRCr in both men and women. Event numbers were small for haemorrhagic stroke. DISCUSSION To a greater degree than is seen in men, eGFRCr underestimates risk of ischaemic stroke and major bleeding in women compared to eGFRCys. The difference between measures is likely explained by non-GFR biology of creatinine and cystatin C. CONCLUSION Enhanced measurement of cystatin C may improve risk stratification for ischaemic stroke and major bleeding and clinical treatment decisions in a general population setting, particularly for women.

A study of the relationship between brachial artery vasodilation and platelet/lymphocyte ratio in diabetic patients with coronary atherosclerosis. J Clin Lab Anal 2023; 37:e24935. [PMID: 37352165 PMCID: PMC10388224 DOI: 10.1002/jcla.24935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 04/11/2023] [Accepted: 06/11/2023] [Indexed: 06/25/2023] Open
Abstract
BACKGROUND To investigate the correlation between brachial artery flow-mediated endothelium-dependent dilation (FMD) and platelet-lymphocyte ratio (PLR) in peripheral blood and coronary atherosclerosis in diabetic patients. METHODS Seventy-five diabetic patients aged 62 ± 9 years, 68% male and 32% female, who underwent brachial artery endothelial function test and coronary CT scan were collected. Coronary artery calcification (CAC) was observed to assess the presence of coronary atherosclerosis, and high-resolution extravascular ultrasound was used to detect FMD. Platelet count and lymphocyte count were recorded by routine blood tests, and PLR was calculated for each study subject. Statistical methods were used to verify the association of FMD and PLR with CAC assessed by CT, respectively. RESULTS Patients with coronary atherosclerosis had decreased FMD and increased PLR compared with patients with normal coronary arteries. Univariate logistic regression analysis showed that CAC score was significantly associated with both FMD (odds ratio: 0.167; 95% confidence interval: 0.049-0.565; p = 0.002) and PLR (odds ratio: 0.127; 95% confidence interval: 0.033-0.484; p = 0.001) at FMD < 5.1% or PLR > 130. The area under the ROC curve of FMD and PLR alone was 0.760 and 0.763, respectively. In addition, combined diagnosis of FMD and PLR showed the highest area under the ROC curve (0.830). CONCLUSION FMD combined with PLR is expected to be a precise diagnostic modality for coronary artery calcification in diabetic patients.

Abstract
AIMS Cardiovascular disease and cancer share common pathogenesis and risk factors. Coronary microvascular dysfunction (CMD), reflecting impaired coronary microvascular dilation in response to stress, is related to a higher risk of major cardiovascular events; however, its association with cancer has not been explored. METHODS AND RESULTS A retrospective study on 1042 patients with non-obstructive coronary artery diseases (NOCADs) was performed. Data regarding demographic, clinical history, diagnostic coronary reactivity test, and cancer occurrence were collected. Coronary microvascular dysfunction was defined as coronary flow reserve (the ratio of hyperaemic blood flow to resting blood flow) ≤2.5. Thirty-four per cent had CMD (67.4% female and the average age was 52.4 ± 12.2 years). Of 917 patients with no history of cancer, 15.5% developed cancer during follow-up [median of 9 (4, 16) years]. Kaplan-Meier analysis showed that CMD patients had lower cancer-free survival compared with those without CMD (log-rank P = 0.005). Cox proportional hazard analyses showed that after adjusting for age, sex, hypertension, diabetes, smoking, and glomerular filtration rate, CMD is independently associated with cancer [hazard ratio, 1.4; 95% confidence interval (CI), 1.09-2.04; P = 0.04]. The rate of major adverse cardiovascular events (MACE) was significantly higher in CMD patients compared with that in non-CMD patients who had a previous history of cancer [odds ratio (OR), 2.5; 95% CI, 1-6.2; P = 0.04] and those with no history of cancer (OR, 1.4; 95% CI, 1.01-1.9; P = 0.044). CONCLUSION Coronary microvascular dysfunction is associated with cancer incidence in patients presenting with NOCADs. This study emphasizes follow-up in patients with CMD to evaluate the risk of MACE as well as potential malignant diseases.

Abstract
Chronic liver diseases (CLDs) are characterized by progressive necrosis of hepatocytes, which leads to liver fibrosis and cirrhosis, and ultimately liver dysfunction. The statistics of 2020 shows that the number of patients with CLDs, including chronic hepatitis, fatty liver, and cirrhosis, may exceed 447 million in China. The liver is a crucial organ for the metabolism of various substances, including sex hormones and lipids. CLDs frequently result in abnormalities in the metabolism of sex hormones, glucose, and lipids, as well as mental and psychological illnesses, all of which are significant risk factors for erectile dysfunction (ED). It has been reported that the prevalence of ED in male patients with CLDs ranges from 24.6 to 85.0%. According to a survey of Caucasians, liver transplantation may improve the erectile function of CLDs patients with ED. This finding supports the link between CLDs and ED. In addition, ED is often a precursor to a variety of chronic diseases. Given this correlation and the significant prevalence of CLDs, it is important to evaluate the epidemiology, risk factors, etiology, and treatment outcomes of ED in male patients with CLDs, expecting to attract widespread attention.

Abstract
The coronary microvasculature is responsible for providing oxygen and nutrients to myocardial tissue. A healthy microvasculature with an intact and properly functioning endothelium accomplishes this by seemless changes in vascular tone to match supply and demand. Perturbations in the normal physiology of the microvasculature, including endothelial and/or vascular smooth muscle dysfunction, result in impaired function (vasoconstriction, antithrombotic, etc.) and structural (hypertrophic, fibrotic) abnormalities that lead to microvascular ischemia and potential organ damage. While coronary microvascular dysfunction (CMD) is the primary pathologic driving force in ischemia with non-obstructive coronary artery disease (INOCA), angina with no obstructive coronary arteries (ANOCA), and myocardial infarction with non-obstructed coronary arteries (MINOCA), it may be a bystander in many cardiac disorders which later become pathologically associated with signs and/or symptoms of myocardial ischemia. Importantly, regardless of the primary or secondary basis of CMD in the heart, it is associated with important increases in morbidity and mortality. In this review we discuss salient features pertaining to known pathophysiologic mechanisms driving CMD, the spectrum of heart diseases where it places a critical role, invasive and non-invasive diagnostic testing, management strategies, and the gaps in knowledge where future research efforts are needed.

Abstract
BACKGROUND Erectile dysfunction (ED) is an early form of atherosclerosis and subclinical myocardial dysfunction. Epicardial fat tissue (EFT) is associated with impaired left ventricular (LV) function, even in the absence of cardiovascular disease. The aim of this study was to investigate the association between EFT and LV systolic function in patients with erectile ED by speckle tracking echocardiography (2D-STE) method. METHODS A total of 129 consecutive patients with ED were compared with 145 age- and sex-matched control subjects. ED was evaluated using the International Index of Erectile Function questionnaire. Thickness of EFT was measured by TTE. Global LV longitudinal strain (LV-GLS) and global LV circumferential strain (LV-GCS) were measured by 2D-STE method. RESULTS The EFT thickness was significantly higher in the patients with ED (p <.01). LV-GLS and LV-GCS were revealed to be more deterioration in the ED group compared to controls (-18.2 ± 2.7 vs. (-21.1 ± 3.9, p<.001; -19.5 ± 4.1 vs. -21.9 ± 3.9, p<.001, respectively). It has been shown that EFT thickness is an independent predictor of LV dysfunction. CONCLUSIONS These results indicate that EFT thickness is associated with subclinical LV systolic dysfunction in patients with ED.

Abstract
Background Women with non‐obstructive coronary artery disease have increased cardiovascular morbidity. The role of risk factors in this population has yet to be established. We aimed to study the predictive effect of triglycerides and the triglyceride/high‐density lipoprotein ratio on major adverse cardiovascular events (MACE) in patients with non‐obstructive coronary artery disease, and to explore the role of lipid lowering therapy in modifying this risk. Methods and Results This is a prospective cohort study enrolling patients with anginal symptoms referred to the cardiac catheterization laboratory for suspected ischemia, who were subsequently diagnosed with non‐obstructive coronary artery disease, defined as no stenosis >20% on angiography. All patients had baseline laboratory testing and were followed for 7.8±4.3 years for the development of major adverse cardiovascular events. We performed Cox proportional hazard testing to determine the effect of triglycerides on risk of major adverse cardiovascular events among men and women by baseline statin use. A total of 462 patients were included. Median age was 53 (Q1, Q3: 45, 62) years. In a Cox proportional hazard model stratified by statin use adjusting for confounders, among those not on baseline statins, triglycerides were independently predictive of major adverse cardiovascular events in women (per 50 mg/dL risk ratio: hazard ratio 1.25 [95% CI: 1.06, 1.47]; P=0.01). This was not true among men. The interaction between triglycerides and sex, and triglycerides and statin was statistically significant. Conclusions Triglyceride levels may play a key role in predicting cardiovascular‐specific risk in women, and statin use may be protective. Further investigation is necessary to better delineate the role of statin use in preventing cardiovascular risk.

Relationship between the Severity of Coronary Artery Disease and Catheter-Associated Urethral Stricture in Patients with Acute Coronary Syndrome. J Tehran Heart Cent 2020; 15:113-118. [PMID: 33552206 PMCID: PMC7827122 DOI: 10.18502/jthc.v15i3.4221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2019] [Accepted: 04/25/2020] [Indexed: 12/03/2022] Open
Abstract
Background: Different arterial segments throughout the vascular system develop similar grades of atherosclerosis concomitantly. Urethral ischemia has been proposed as a cause of urethral stricture. Therefore, we aimed to investigate the relationship between coronary artery disease severity using a SYNTAX score and urethral stricture occurrence after urethral catheterization in patients with non-ST-segment-elevation acute coronary syndrome (ACS). Methods: This retrospective study consisted of 306 men with urethral catheters that were diagnosed with ACS and underwent coronary angiography between January 2016 and January 2018 in Kars Kafkas University and Osmaniye Government Hospital, Turkey. Hospital records were reviewed to collect the follow-up data of the patients regarding the occurrence of urethral stricture after urethral catheterization. The study population was divided into 2 groups according to urethral stricture development, and both groups were compared statistically. Results: SYNTAX scores were significantly higher in patients with urethral stricture than in those without urethral stricture (14.86±7.11 vs. 29.25±9.79; P<0.001). The SYNTAX score (OR=1.27; 95% CI: 1.16-1.39; P<0.001), diabetes, and serum albumin were found to be the independent predictors of urethral stricture. The receiver operating characteristic curve analysis showed that the cutoff value of the SYNTAX score for urethral stricture prediction was greater than 22.5, with 76.7% sensitivity and 85.1% specificity (AUC=0.88, 95% CI: 0.84-0.91; P<0.001). Conclusion: Coronary artery disease severity graded according to the SYNTAX score is an independent predictor of urethral stricture occurrence in ACS patients with a urethral catheter inserted.

Abstract
This study aimed to gain insight into the underlying pathogenesis of erectile dysfunction in young men under the age of 40 years without widely-known risk factors. Compared with normal controls, patients with erectile dysfunction had increased carotid intima–media thickness, fasting levels of blood glucose and insulin, and homeostatic model assessment index, as well as lower flow-mediated vasodilation and testosterone levels (P < 0.05), though all of these values were within their respective normal range. Multivariate logistic regression analysis identified carotid intima–media thickness, flow-mediated vasodilation, insulin level, and homeostatic model assessment index as significant predictors of erectile dysfunction. Young men with flow-mediated vasodilation <10.65% were 11.645 times more likely to have erectile dysfunction, young men with carotid intima–media thickness >0.623 mm had a 4.16-fold, and young men with homeostatic model assessment index >1.614 had a 5.993-fold greater risk of having erectile dysfunction. In conclusions, in young men with normal results from general clinical screening, an increased carotid intima–media thickness and homeostatic model assessment index and reduced flow-mediated vasodilation were associated with a higher incidence of erectile dysfunction. Erectile dysfunction may appear before the detection of traditional cardiovascular risk factors and may be the earliest clinical sign of subclinical cardiovascular disease.

Abstract
BACKGROUND Coronary artery disease (CAD) is a leading cause of morbidity and death. Early diagnosis of patients with left main and/or three-vessel disease (LM/3VD) among acute coronary syndrome (ACS) patients is beneficial. The relation between erectile dysfunction (ED) and cardiovascular diseases was previously noticed. The aim of our work was to find out if the severity of ED could predict the presence of LM/3VD in ACS patients. PATIENTS AND METHODS Eighty-five male patients with ACS were included in the study. Clinical assessment, estimation of international index of erectile function (IIEF) score, and coronary angiography were performed in all patients. Gensini score was calculated to assess the severity of CAD. Based on IIEF score, the patients were divided into two groups: Group 1: patients with mild or no ED (IIEF score ≥17), Group 2: patients with moderate or severe ED (IIEF score <17). RESULTS Patients with IIEF score <17 had significantly higher prevalence of LM CAD (4.3% versus 18.4%, p=0.035), 3VD (17% versus 39.5%, p=0.021) and LM/3VD (21.3% versus 55.3%, p=0.0012), as well as higher mean Gensini score (23.5±10.8 versus 34.1±12.7, p=0.0001). The independent predictors of LM/3VD in order of significance were: age, heart rate, IIEF <17, Killip class >1, and ST-depression or ST-elevation in lead aVR ≥1mV. There was a significant negative correlation between IIEF score and Gensini score (r=-0.383, p=0.0003). CONCLUSION The presence of moderate or severe ED in men with ACS is associated with higher Gensini score and more incidence of LM/3VD. IIEF score <17 was an independent predictor of LM/3VD.

Abstract
PURPOSE The aim of this study was to investigate the association between fragmented QRS and left ventricular (LV) systolic function in patients with erectile dysfunction (ED). METHODS A total of 106 patients with ED and without a history of coronary artery disease (CAD) were compared with 54 age- and gender-matched healthy controls. LV systolic function was evaluated using speckle tracking echocardiography via global longitudinal strain (GLS) and global circumferential strain (GCS). The patients with ED were compared with healthy controls. The study group was further subdivided into fQRS (+) and fQRS (-) groups and compared with each other. RESULTS The frequency of fQRS was significantly higher in the patients with ED (p = 0.01). The frequency of fQRS was higher in the patients with mild and moderate ED, and significantly higher in those with severe ED (p < 0.001). LV-GLS (%) was 17.46 ± 1.37 and 20.05 ± 1.42 in the fQRS (+) and fQRS (-) groups, respectively (p ≤ 0.001). LV-GCS (%) was 17.33 ± 0.81 and 18.55 ± 0.92 in the fQRS (+) and fQRS (-) groups, respectively (p ≤ 0.001). fQRS and age were independent predictors of LV-GLS. CONCLUSIONS The frequency of fQRS was higher in the patients with ED even in the absence of overt CAD. In the patients with ED, the fQRS (+) group had significantly lower values of LV-GLS and LV-GCS. These results indicate that presence of fQRS is associated with subclinical LV dysfunction in patients with ED.

Chronic inhibition of lipoprotein-associated phospholipase A 2 does not improve coronary endothelial function: A prospective, randomized-controlled trial. Int J Cardiol 2018; 253:7-13. [PMID: 29306475 DOI: 10.1016/j.ijcard.2017.09.171] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2017] [Revised: 09/07/2017] [Accepted: 09/18/2017] [Indexed: 12/14/2022]
Abstract
AIMS Lipoprotein-associated phospholipase A2 (Lp-PLA2), a novel biomarker for vascular inflammation, is associated with coronary endothelial dysfunction (CED) and independently predicts cardiovascular events. The current study aimed to determine whether darapladib, an orally administered Lp-PLA2 inhibitor, improved CED. METHODS AND RESULTS Fifty-four patients with CED were enrolled in a double-blinded randomized placebo-controlled trial, and were randomized to receive oral darapladib, 160mg daily, or placebo. Coronary angiography and invasive coronary endothelial function assessment were performed at baseline and post-6months of treatment. Primary endpoints were change in coronary artery diameter and coronary blood flow in response to acetylcholine. Additionally, Lp-PLA2 activity was measured at baseline and on follow-up to evaluate for adherence and drug effect. Fifty-four patients were randomized to placebo (n=29) and darapladib (n=25). Mean age in darapladib group was 55.2.±11.7years vs. 54.0±10.5years (p=0.11). On follow-up, there was no significant difference in the percent response to acetylcholine of coronary artery diameter in treatment vs. placebo group (+3 (IQR -9, 15) vs. +3 (-12, 19); p=0.87) or coronary blood flow (-5 (IQR -24, 54) vs. 39 (IQR -26, 67); p=0.41). There was significant reduction in Lp-PLA2 activity in the treatment arm vs. placebo (-76 (IQR -113, -52) vs. -7(-21, -7); p<0.001). DISCUSSION Lp-PLA2 inhibition with darapladib did not improve coronary endothelial function, despite significantly reduced Lp-PLA2 activity with darapladib. This study suggests endogenous Lp-PLA2 may not play a primary role in coronary endothelial function in humans. CLINICALTRIALS. GOV IDENTIFIER NCT01067339.

Abstract
Objective To investigate the association between the severity of erectile dysfunction (ED) and coronary artery disease (CAD) in men undergoing coronary angiography for angina or acute myocardial infarct (AMI). Material and Methods We studied 132 males who underwent coronary angiography for first time between January and November 2010. ED severity was assessed by the international index of erectile function (IIEF-5) and CAD severity was assessed by the Syntax score. Patients with CAD (cases) and without CAD (controls) had their IIEF-5 compared. In the group with CAD, their IIEF-5 scores were compared to their Syntax score results. Results We identified 86 patients with and 46 without CAD. The IIEF-5 score of the group without CAD (22.6±0.8) was significantly higher than the group with CAD (12.5±0.5; p<0.0001). In patients without ED, the Syntax score average was 6.3±3.5, while those with moderate or severe ED had a mean Syntax score of 39.0±11.1. After adjustment, ED was independently associated to CAD, with an odds ratio of 40.6 (CI 95%, 14.3-115.3, p<0.0001). The accuracy of the logistic model to correctly identify presence or absence of CAD was 87%, with 92% sensitivity and 78% specificity. The average time that ED was present in patients with CAD was 38.8±2.3 months before coronary symptoms, about twice as high as patients without CAD (18.0±5.1 months). Conclusions ED severity is strongly and independently correlated with CAD complexity, as assessed by the Syntax score in patients undergoing coronariography for evaluation of new onset coronary symptoms.

Uric Acid Is Associated With Inflammation, Coronary Microvascular Dysfunction, and Adverse Outcomes in Postmenopausal Women. Hypertension 2016; 69:236-242. [PMID: 27993955 DOI: 10.1161/hypertensionaha.116.08436] [Citation(s) in RCA: 70] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2016] [Revised: 09/21/2016] [Accepted: 11/07/2016] [Indexed: 12/22/2022]
Abstract
Uric acid is a risk factor for coronary artery disease in postmenopausal women, but the association with inflammation and coronary endothelial dysfunction (CED) is not well defined. The aim of this study was to determine the relationship of serum uric acid (SUA), inflammatory markers, and CED. In this prospective cohort study, SUA, high-sensitivity C-reactive protein levels, and neutrophil count were measured in 229 postmenopausal women who underwent diagnostic catheterization, were found to have no obstructive coronary artery disease, and underwent coronary microvascular function testing, to measure coronary blood flow response to intracoronary acetylcholine. The average age was 58 years (interquartile range, 52-66 years). Hypertension was present in 48%, type 2 diabetes mellitus in 5.6%, and hyperlipidemia in 61.8%. CED was diagnosed in 59% of postmenopausal women. Mean uric acid level was 4.7±1.3 mg/dL. Postmenopausal women with CED had significantly higher SUA compared with patients without CED (4.9±1.3 versus 4.4±1.3 mg/dL; P=0.02). There was a significant correlation between SUA and percent change in coronary blood flow to acetylcholine (P=0.009), and this correlation persisted in multivariable analysis. SUA levels were significantly associated with increased neutrophil count (P=0.02) and high-sensitivity C-reactive protein levels (P=0.006) among patients with CED, but not among those without CED. SUA is associated with CED in postmenopausal women and may be related to inflammation. These findings link SUA levels to early coronary atherosclerosis in postmenopausal women.

Abstract
Cardiovascular disease is the leading cause of death worldwide. In the presence of signs and symptoms of myocardial ischaemia, women are more likely than men to have no obstructive coronary artery disease (CAD). Women have a greater burden of symptoms than men, and are often falsely reassured despite the presence of ischaemic heart disease because of a lack of obstructive CAD. Coronary microvascular dysfunction should be considered as an aetiology for ischaemic heart disease with signs and symptoms of myocardial ischaemia, but no obstructive CAD. Coronary microvascular dysfunction is defined as impaired coronary flow reserve owing to functional and/or structural abnormalities of the microcirculation, and is associated with an adverse cardiovascular prognosis. Therapeutic lifestyle changes as well as antiatherosclerotic and antianginal medications might be beneficial, but clinical outcome trials are needed to guide treatment. In this Review, we discuss the prevalence, presentation, diagnosis, and treatment of coronary microvascular dysfunction, with a particular emphasis on ischaemic heart disease in women.

Abstract
AIM: To investigate the prevalence of erectile dysfunction (ED) and its association with depression in patients with chronic viral hepatitis.
METHODS: This single center cross-sectional study was conducted from August 2013 through January 2014. All outpatients with chronic viral hepatitis in our liver clinic between 18 and 80 years of age were considered eligible for this study. The exclusion criteria included well-established causes of ED, such as diabetes, hypertension, hyperlipidemia, alcohol abuse, liver cirrhosis, ischemic heart disease, renal disease, neurologic disease, and malignancy. We also excluded the patients who had incompletely answered the questionnaires. ED was assessed using the validated Korean version of the International Index of Erectile Function (IIEF-5) scale. The Korean version of the self-administered Beck Depression Inventory (BDI) scale was used to assess depression in the patients. Demographic and medical data were obtained from the patients’ medical records. Current or past history of psychiatric diagnosis and drug history including the use of an antiviral agent and an antidepressant were also recorded.
RESULTS: A total of 727 patients met the initial eligibility criteria. Six hundred seventeen patients were excluded because their medical records contained one or more of the previously determined exclusion criteria. The remaining 110 patients were assessed based on the BDI and IIEF-5 questionnaires. Based on the IIEF-5 scale, the prevalence of ED among patients with chronic viral hepatitis was 40%. Compared with the non-ED group, patients in the ED group were older. The proportion of patients in the ED group who had a job or who were naïve peg-interferon users was lower than that in patients in the non-ED group. Patients with ED had significantly lower scores on the IIEF-5 scale than patients without ED (11.75 ± 4.88 vs 21.33 ± 1.86, P = 0.000). Patients with ED rated significantly higher scores on the BDI scale compared with patients without ED (12.59 ± 7.08 vs 5.30 ± 4.00, P = 0.000). Also, the IIEF-5 scores were negatively correlated with age, employment, and BDI scores. In the multiple logistic regression analysis, age and depression were independently associated with erectile dysfunction (P = 0.019 and 0.000, respectively).
CONCLUSION: Patients with chronic viral hepatitis have a high prevalence of ED. Age and depression are independent factors for ED in male patients with chronic viral hepatitis.

Abstract
Based on the mechanism of pathophysiology, thalassemia major or transfusion-dependent thalassemia patients may have an increased risk of developing organic erectile dysfunction resulting from hypogonadism. However, there have been few studies investigating the association between erectile dysfunction and transfusion-naive thalassemia populations. We constructed a population-based cohort study to elucidate the association between transfusion-naive thalassemia populations and organic erectile dysfunction. This nationwide population-based cohort study involved analyzing data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database, with a follow-up period extending to the end of 2011. We identified men with transfusion-naive thalassemia and selected a comparison cohort that was frequency-matched with these according to age, and year of diagnosis thalassemia at a ratio of 1 thalassemia man to 4 control men. We analyzed the risks for transfusion-naive thalassemia men and organic erectile dysfunction by using Cox proportional hazards regression models. In this study, 588 transfusion-naive thalassemia men and 2337 controls were included. Total 12 patients were identified within the thalassaemia group and 10 within the control group. The overall risks for developing organic erectile dysfunction were 4.56-fold in patients with transfusion-naive thalassemia men compared with the comparison cohort after we adjusted for age and comorbidities. Our long-term cohort study results showed that in transfusion-naive thalassemia men, there was a higher risk for the development of organic erectile dysfunction, particularly in those patients with comorbidities.
