Erectile dysfunction (ED) after ischemic stroke: association between prevalence and site of lesion

High prevalence of erectile dysfunction in male patients with acute stroke was associated with age but not to modifiable cardiovascular risk factors

Background

Erectile dysfunction (ED) and stroke share common risk factors, and symptoms of ED often precede the development of clinical cardiovascular disease (CVD). However, little is known about how ED is associated with cardiovascular (CV) risk factors in patients who had a stroke and if concomitant ED is a marker of more severe CVD.

Aims

We aimed to identify the prevalence of ED and CV risk factors in patients admitted with a stroke or transient ischaemic attack (TIA). Further, we wanted to test if self-reported ED associated with presence of CV risk factors, and if patients with ED had increased stroke severity compared with patients without ED.

Methods

This was a post hoc analysis of data retrieved in a cross-sectional survey from two non-comprehensive stroke units in Denmark. Multiple logistic regression adjusted for covariates was performed to investigate the association between CV risk factors and self-reported ED.

Results

We included 287 male patients of which 116 (40.4%) had self-reported ED. Advanced age was significantly associated with self-reported ED (reference ≤60 years: OR 3.93, 95% CI 1.84 to 8.37 for men 71-80 years and OR 4.61, 95% CI 1.92 to 11.08 for men >80 years). Self-reported ED was not significantly associated with CV risk factors or stroke severity.

Discussion

Four in 10 men with acute stroke or TIA reported to have ED prior to their stroke, and this was associated with age rather than CV risk factors. Hence, self-reported ED was not restricted to the CVD load, nor was ED a risk marker for increased stroke severity. However, our population was of high age with well-established CVD, and the presence of ED may be a stroke risk marker in younger patients who had a stroke. Based on the prevalence, potential treatment of ED should be addressed in stroke recovery.

Sexual disorders post-stroke: Description of a cohort of patients followed in rehabilitation

INTRODUCTION

The impairments resulting from a stroke can be multiple, including urinary and/or sexual dysfunctions. This acquired brain injury disrupts neurological control of sexual responses.

MAIN OBJECTIVE

to describe sexual disorders, after a first episode of stroke, in a population followed in a physical medicine and rehabilitation (PMR) center.

SECONDARY OBJECTIVES

to gather patients' expectations and PMR physicians' opinions on this subject.

METHOD

Observational, retrospective study in two PRM centers. Post-stroke sexuality was assessed using two validated questionnaires [for men: International Index of Erectile Function 15 (IIEF15) and for women: Female Sexual function Index (FSFI)]. Patients were asked 3 questions to approximate their expectations, and PRM physicians were asked 2 questions for their opinions.

RESULTS

Twenty-four subjects included (17 men/7 women). Thirteen had no post-stroke sexuality. Erectile function was analysable in 4 subjects, 3 of whom had moderate to severe erectile dysfunction. In women, female sexual dysfunction concerned 6/7 women, including lubrication. Ninety-six percent of subjects had never discussed sexuality with their PRM physician. Only 33% would have liked information on this subject. Our PRM physicians rarely discuss post-stroke sexual disability.

CONCLUSION

Post-stroke sexual disorders occur in both sexes. All areas of sexuality may be affected. A large-scale, prospective, controlled, multicenter study is needed to establish stroke as the direct neurological cause of sexual impairment.

Complex Dysautonomia in a Patient With Cerebral Cavernous Malformations Due to a KRIT1 Pleiotropic Gene Mutation

Dysautonomia is a disruption of the body's autonomic processes. Symptoms vary among patients, depending on the underlying disease pathways. Given that symptoms can affect all organ functions, dysautonomia often significantly impacts quality of life. However, due to its complex and varied presentation, early recognition of dysautonomia remains a challenge, yet it is crucial for improving patient outcomes. We report a case of a patient with a KRIT1 mutation presenting with dysautonomia causing urological, sexual, and bowel dysfunction. We hypothesize that the patient's symptoms are due to a pontine cavernous malformation (CM) caused by the KRIT1 mutation. A literature review was conducted to establish a link between pontine CM and dysautonomia.

Genetically predicted cardiovascular diseases could increase the risk of erectile dysfunction: a bidirectional Mendelian randomization

PURPOSE

Erectile dysfunction (ED) often appears concomitantly with cardiovascular diseases (CVDs). However, the causal relationship between ED and CVDs is still unclear. This study aimed to investigate the causal effects between CVDs and ED using bidirectional Mendelian randomization (MR).

METHODS

ED data (6175 cases and 217,630 controls) were obtained from the IEU OpenGWAS project. Seven types of CVDs were acquired in our study, including stroke (Sample size = 440,328), myocardial infection (Sample size = 184,305), coronary heart disease (Sample size = 86,995), hypertension (Sample size = 36,683), heart failure (Sample size = 208,178), atrial fibrillation (Sample size = 1,030,836), and coronary artery disease (Sample size = 141,217). Inverse variance weighted (IVW) was selected as the primary method for MR analysis.

RESULTS

IVW results indicated that stroke (OR = 1.14, 95% CI = 1.02-1.29, P = 0.025), coronary artery disease (OR = 1.09, 95% CI = 1.02-1.16, P = 0.013), coronary heart disease (OR = 1.07, 95% CI = 1.01-1.13, P = 0.017), myocardial infection (OR = 1.09, 95% CI = 1.02-1.17, P = 0.011), and atrial fibrillation (OR = 1.06, 95% CI = 1.00-1.12, P = 0.04) were causally associated with ED. The reverse MR analysis suggested that ED did not influence the prevalence of CVDs.

CONCLUSION

These findings highlighted CVDs as causal risk factors for ED, but ED did not directly result in the development of CVDs. Regular monitoring of the erectile function of individuals with CVDs, along with implementing appropriate preventive measures, might help reduce the incidence of ED and enhance the sexual well-being of patients with CVDs.

Poststroke Erectile Dysfunction in Cameroon: Prevalence, Associated Factors, and Quality of Life

Background

Stroke is a severe disease due to its morbidity-mortality. It is the first cause of acquired disability including erectile dysfunction (ED). The purpose of this study was to determine the prevalence of ED in stroke patients at the Douala General Hospital, to identify associated factors and to evaluate their quality of life.

Materials and Methods

A cross-sectional study was conducted over a period of seven months from November 2016 to May 2017 on two groups of patients in neurology, cardiology, and endocrinology units of the Douala General Hospital (Cameroon): stroke patients (stroke+) and nonstroke patients (stroke-). We collected sociodemographic and clinical data using a preestablished questionnaire. Erectile function was assessed using International Index of Erectile Function (IIEF-5). Associated and predictive factors were determined using univariate and multivariate analyses. Results were significant for a p value < 0.05.

Results

A total of 269 patients were included, among them 87 stroke+ (32.34%) and 182 stroke- (67.66%) (controlled group). The mean age was 56.37 ± 12.89 years and 57.18 ± 10.24 years of stroke+ and stroke-, respectively (p = 0.608). Prevalence of poststroke ED was 64.4% (OR = 3.41, 95% CI: 1.99-5.82, p < 0.001). The average time of occurrence of the poststroke ED was 5 ± 5.85 months. Diabetes and dyslipidemia were the predictive factors of occurrence of poststroke ED. Depression was found both in stroke+ with ED and stroke+ without ED with no difference (p = 0.131).

Conclusion

About two-thirds of stroke patients developed ED. Diabetes and dyslipidemia were predictive factors of ED in stroke patients.

Significant Increase of Erectile Dysfunction in Men With Post-stroke: A Comprehensive Review

Men with erectile dysfunction (ED) are considered to be at risk from stroke events. Conversely, post-stroke patients are also at high risk of ED, whereas a quantitative result from all the relevant studies has not been previously addressed. Therefore, we have performed a comprehensive review and meta-analysis on this issue. This study was registered on PROSPERO (ID No. CRD42021226618). Twenty studies with a total of 3,382 stroke events were included, of which six studies were included for quantitative analysis, and the remaining 14 studies were calculated for the ratio of ED. Synthetic results from four eligible studies providing the ED cases showed that stroke patients were associated with a significantly higher risk of ED than the general population [pooled relative risk (RR) = 3.32, 95% confidence interval (CI): 1.25–8.82, P = 0.016]. Men with stroke were also found to be associated with a significant decline in International Index of Erectile Function −5 (IIEF-5) score as compared with the healthy controls [three studies, standard mean differences (SMD) = −1.8, 95% CI: −2.94 to −0.67, P = 0.002]. The prevalence of ED in post-stroke patients among 14 studies ranged from 32.1 to 77.8%, which was dramatically higher than that of the general population. The result of the GRADE-pro revealed that the quality of the evidence in this study was moderate. The present study has confirmed the high prevalence of ED in men with stroke. ED in stroke patients is a result of both neurological and psychological factors. Rehabilitative interventions rather than phosphodiesterase-5 (PDE-5) inhibitors are recommended to improve the erectile function for those survivors with ED.

Assessment methods in sexual rehabilitation after stroke: a scoping review for rehabilitation professionals

PURPOSE

The aim was to identify and describe the assessment methods used by rehabilitation professionals to evaluate sexuality for individuals post-stroke, as well as the domains of sexuality addressed.

METHODS

Seven databases were selected for this scoping review. Articles needed to meet these inclusion criteria: published studies with a sample of ≥ 50% stroke clients and describing a quantitative or qualitative assessment method that could be used by rehabilitation professionals. This study was conducted following the PRISMA guidelines and domains of sexuality were categorized using the ICF core set for stroke.

RESULTS

Of the 2447 articles reviewed, the 96 that met the selection criteria identified a total of 116 assessment methods classified as standardized assessment tools (n = 62), original questionnaires (n = 28), semi-structured interviews (n = 16) or structured interviews (n = 10). Sexual functions were predominantly assessed using standardized tools, while intimate relationships and partner's perspective were generally addressed more by original questionnaires and qualitative methods. A stepwise approach combining relevant assessment methods is presented.

CONCLUSIONS

Individually, these diverse assessment methods addressed a limited scope of relevant domains. Future research should combine quantitative and qualitative methods to encompass most domains of sexuality of concern to post-stroke individuals.IMPLICATIONS FOR REHABILITATIONMost of the studies reviewed here used quantitative methods to assess sexuality, rather than qualitative methods, and mostly used standardized assessment tools.Few assessment methods covered all domains related to sexuality.Qualitative methods and standardized assessment tools were shown to be complementary, therefore emphasizing the added value of mixed methods in assessing sexuality after a stroke.Among the methods that were reviewed, certain would be more suitable for the identification of the need to address sexuality (e.g., Life Satisfaction Checklist-11) and others to assess more thoroughly sexuality (e.g., Change in Sexual Functioning Questionnaire (CSFQ-14)).

Neurogenic Erectile Dysfunction. Where Do We Stand?

Erectile Dysfunction (ED) is the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance, causing tremendous effects on both patients and their partners. The pathophysiology of ED remains a labyrinth. The underlying mechanisms of ED may be vasculogenic, neurogenic, anatomical, hormonal, drug-induced and/or psychogenic. Neurogenic ED consists of a large cohort of ED, accounting for about 10% to 19% of all cases. Its diversity does not allow an in-depth clarification of all the underlying mechanisms nor a “one size fits all” therapeutical approach. In this review, we focus on neurogenic causes of ED, trying to elucidate the mechanisms that lie beneath it and how we manage these patients.

Risk Factors, Depression, and Drugs Influencing Sexual Activity in Individuals With and Without Stroke

PURPOSE

The aim of the study was to analyze factors affecting sexual activity in individuals with and without stroke, ages 40-59 years, in a national, cross-sectional, population-based sample derived from the National Health and Nutrition Examination Survey (NHANES).

DESIGN

Descriptive, cross-sectional survey.

METHODS

Data were obtained from the NHANES (2011-2012) data set from individuals (N = 3,649) completing items related to cardiovascular risk factors, drugs, and sexual activity. Data were analyzed using chi-square, t tests, and logistic regression.

FINDINGS

Overall, number of drugs, smoking, and depression significantly predicted sexual activity. When comparing sexually active to not sexually active, those with stroke had significantly less sexual activity (t = 2.822, p = .005) and reduced sexual activity per week or month (χ = 16.275, p = .005, df = 4). Those taking angiotensin-converting enzyme inhibitors and statins had reduced sexual activity.

CONCLUSIONS/CLINICAL RELEVANCE

Findings illustrate the importance of risk factor modification and nurses engaging in sexual assessment, education, and counseling to support sexual quality of life in younger individuals with stroke.

Acupuncture for erectile dysfunction in post-stroke patients: Study Protocol Clinical Trial (SPIRIT Compliant)

INTRODUCTION

Erectile dysfunction refers to the continued inability of the penis to reach and maintain sufficient erections to achieve a satisfactory sex life and last at least 6 months. As part of traditional Chinese medicine, acupuncture has been widely used in clinical practice. In order to evaluate, the exact effect of acupuncture on the clinical efficacy of patients with Post-stroke Erectile dysfunction (PSED), this experiment uses randomized controlled experiments.

METHODS/DESIGN

This pragmatic randomized controlled trial will recruit 103 patients who are diagnosed with PSED. Simple randomization to conventional treatment with a 1:1 allocation ratio will be used. Ten 30-min acupuncture sessions will be provided to patients assigned to the Intervention group. All participants will continue to receive conventional treatment. The selection of outcomes will be evaluated by International Erectile Function Index-5 (IIEF-5) score at week 8.

DISCUSSION

This trial may provide evidence regarding the clinical effectiveness, safety, and cost-effectiveness of acupuncture for patients with PSED.

Determinants of sexual function and dysfunction in men and women with stroke: A systematic review

AIM

The aim of this systematic review was to examine determinants of sexual function and dysfunction in men and women poststroke, and to evaluate effectiveness of interventions.

METHODS

A systematic review was conducted using the databases of PubMed, Medline, CINAHL, Cochrane, and Psychinfo, for studies published between January, 2000 and October, 2016. Included were original research, adult ≥18 years, English language, and experimental and non-experimental designs. Excluded were studies of stroke caused by sexual activity, stroke triggered unusual behaviours, and changes in sexual orientation. Studies were evaluated for quality using The Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Of 19 studies reviewed, 13 were descriptive, three case-controlled and three intervention/randomised controlled trials (RCTs) designs.

RESULTS

Participants across studies were predominantly men (90%), with moderate erectile dysfunction (ED), and mild depression. Changes in sexual activity, sexual dissatisfaction and sexual dysfunction were common, including decreased libido, orgasmic problems and ED, significantly worse from pre to poststroke. Results for side of hemiparesis and sexual dysfunction were inconclusive. Sexual rehabilitation interventions differed, but resulted in improved sexual satisfaction, sexual activity frequency and erectile function in two studies.

CONCLUSIONS

Sexual dysfunction commonly occurred poststroke, continuing for months or as long as 2 years. Intervention studies were limited, with only two RCTs, thus, firm conclusions cannot be made. Few studies included women or younger stroke patients, indicating the need for further RCTs with larger and more diverse samples.
