Prevalence of erectile dysfunction in patients with chronic kidney disease: a systematic review and meta-analysis

Associations between organic erectile dysfunction and the risk of herpes zoster and postherpetic neuralgia in men

BACKGROUND

Whether erectile dysfunction (ED) leads to considerable stress for affected men remains unclear? In this study, we investigated whether organic ED (OED) is associated with increased risks of herpes zoster (HZ) and postherpetic neuralgia (PHN).

METHODS

A representative subset of Taiwan's National Health Insurance Research Database was employed for this study. Enrollees with OED from the years 2000 to 2018 were selected. To ensure comparability between the case and control groups, we implemented 1:1 propensity score matching based on age, index year, comorbidities, and medications.

RESULTS

The case group included 20,808 patients with OED, while the control group consisted of 20,808 individuals without OED. The OED group exhibited a significantly elevated risk of HZ (adjusted hazard ratio [aHR] = 1.74) and PHN (aHR = 1.56) compared to the non-OED group.

CONCLUSIONS

Men experiencing OED seem to face elevated risks of HZ and PHN compared to those without OED. ED may serve as a warning sign for individuals at HZ risk.

Relationship between vitamin D receptors gene polymorphism and arteriogenic erectile dysfunction

BACKGROUND

Over the past few decades, a number of studies have linked vitamin-D deficiency with ED (Erectile dysfunction) risk factors. There is a clear correlation between VD (vitamin-D) levels and ED, according to observational and interventional researches that have been reported in the literature. This crucial information encouraged scientists to investigate the impact of VD on erectile function in greater detail. The fact that vitamin D is a component of a healthy penis that begins in early life has just come to light, however there haven't been many research looking at the connection between vitamin D receptor gene polymorphism and erectile dysfunction.

OBJECTIVE

To evaluate the relationship between arteriogenic erectile dysfunction and the vitamin D receptor gene polymorphism.

SUBJECTS AND METHODS

Between October 2022 and October 2023, at Al-Azhar University Hospitals, 40 patients with arteriogenic ED and 40 healthy controls underwent informed consent, a detailed history, a physical examination, a penile duplex ultrasound and the extraction of peripheral blood to determine the type of polymorphism for each of the vitamin D receptors: FokI, BsmI, ApaI and TaqI by polymerase chain reaction (PCR).

RESULTS

There is no statistically significant association between arteriogenic erectile dysfunction and the vitamin D receptors (VDR) gene polymorphisms FokI, BsmI, ApaI and TaqI.

CONCLUSION

Since there is no statistically significant association between the polymorphism of the vitamin D receptor (VDR) gene and arteriogenic erectile dysfunction, it is advised to investigate other VDR gene polymorphisms as well as alternative clinical subtypes of erectile dysfunction.

Nutritional aphrodisiacs: Biochemistry and Pharmacology

In 2022, the global prevalence of erectile dysfunction (ED) was estimated to be at least 150 million cases. This number is greatly suspected to be underestimate as most men withhold information about ED. Also, about 15% of world population have infertility troubles, and male factors are responsible for almost half of these cases. Studies have shown that the quality of semen has decreased in the past several decades owing to various health factors and environmental toxicants. The current medical interventions involve the inhibition of phosphodiesterase 5 which suffer from serious side effects and costly. One of the popular and most sought interventions are the natural and nutritional remedies as they are foods in essence and potentially with no harm to the body. Therefore, the goal of this paper is to provide a review of the most common nutritional aphrodisiacs with increasing libido and fertility highlighting the potential active constituents as well as the underlying mechanisms.

Testosterone deficiency in men with end stage renal disease and kidney transplantation: a narrative review

Testosterone deficiency is a prevalent condition that frequently affects individuals with end-stage renal disease (ESRD) and those who have undergone renal transplantation. While the etiology of this condition is complex, its implications in this population are far-reaching, impacting various domains such as endocrine profile, sexual and erectile function, bone mineral density (BMD), anemia, and graft survival following renal transplantation. Herein, we review the most recent literature exploring the pathophysiology of testosterone deficiency in ESRD and renal transplant patients, examining its diverse effects on this demographic, and assessing the advantages of testosterone replacement therapy (TRT). Existing evidence suggests that TRT is a safe intervention in ESRD and renal transplant patients, demonstrating improvements across multiple domains. Despite valuable insights from numerous studies, a critical need persists for larger, high-quality prospective studies to comprehensively grasp the nuances of TRT, especially in this vulnerable population. Proactive screening and treatment of testosterone deficiency may prove beneficial, emphasizing the urgency for further research in this area.

The problem of calculating the prevalence of sexual dysfunction: a meta-analysis attending gender

INTRODUCTION

Sexuality is an integral part of human health, and sexual dysfunctions are prevalent issues that affect men and women. While reviews on sexual dysfunctions in various diseases have been conducted, overall data are scarce.

OBJECTIVES

To update the overall prevalence of sexual dysfunctions from available prevalence studies on both sexes.

METHODS

We used a 2-phase selection process to include cross-sectional studies that were conducted on the adult population and published between 2017 and 2022. The extracted data were prevalence, methodology, sample size, and location. Sensitivity and subgroup analyses were conducted to assess heterogeneity.

RESULTS

This review analyzed 4407 studies. Twenty-three met the established criteria: 9 on the male population and 14 on the female population. The meta-analysis included 7 articles on males and 13 on females. The prevalence of sexual dysfunction was 31% in men and 41% in women, with significant heterogeneity among the studies. Sociocultural differences and use of varying measurement methods were identified as the main factors contributing to heterogeneity. Subgroup analysis revealed decreased heterogeneity among studies that used the Female Sexual Function Index as a diagnostic tool for females.

CONCLUSIONS

The review highlights the notable variability in results due to methodological and geographic variations. Therefore, enhancing the training of professionals and standardizing the recording of patient data-through the Female Sexual Function Index and Male Sexual Health Questionnaire or by developing new ones for this purpose-could improve the consistency of research on sexual health.

Exploring Symptom Clusters in Chinese Patients with Diabetic Kidney Disease: A Network Analysis

Purpose

The research on symptom management in patients with diabetic kidney disease (DKD) has shifted from separate symptoms to symptom clusters and networks recently. This study aimed to evaluate the unpleasant symptoms of DKD patients, and to investigate how these symptom clusters could affect patients.

Methods

408 DKD patients were recruited in this cross-sectional study. The symptoms of DKD patients were measured using the modified Dialysis Symptom Index. Network analysis was employed to evaluate the symptom network and the characteristics of individual nodes, while factor analysis was utilized to identify symptom clusters.

Results

Blurred vision was the most prevalent symptom among DKD patients. The symptoms identified as the most distressing, severe, and frequent were light headache or dizziness, arteriovenous fistula/catheterization pain, and diarrhea, respectively. Five symptom clusters were obtained from factor analysis, and the most central symptom cluster in the entire symptom network was sexual dysfunction.

Conclusion

This study identified five symptom clusters in Chinese DKD patients, with sexual dysfunction emerging as the most central cluster. These findings carry significant clinical implications, underscoring the necessity of assessing symptom clusters and their associations to enhance symptom management in DKD patients. Further research is essential to elucidate the underlying mechanisms of symptoms and to clarify the associations among symptoms in DKD patients across different disease trajectories or treatment modalities.

The Impact of Nutritional Status on Sexual Function in Male Kidney Transplant Recipients

Background and Objectives: Sexual function and nutritional status assessment are relevant topics in chronic kidney disease patients. This study was designed to investigate whether bioelectrical impedance analysis-derived nutritional parameters, nutritional biomarkers, and handgrip strength influence sexual function and to analyze the changes in sexual function after kidney transplantation in men. Materials and Methods: Fifty-four men with kidney failure who had undergone replacement therapy entered the study. In addition, sexual function and nutritional status were evaluated before kidney transplantation and 12 months after. We used the International Index of Erectile Function, bioelectrical impedance analysis, three different malnutrition screening tools, handgrip strength, and anthropometric measurements. The demographic profiles and biochemical nutritional markers were collected. Results: Sexual inactivity was associated with a lower phase angle (6 (1) vs. 7 (1), p < 0.05) and a higher fat mass index (7 (5) vs. 3 (4), p < 0.05). Normal erectile function before kidney transplantation was significantly related to higher fat-free mass (67 (11) vs. 74 (7), p < 0.05) and lean mass (64 (10) vs. 70 (7), p < 0.05). The improvement in erectile function after kidney transplantation was nonsignificant (44% vs. 33%, p = 0.57). Only a weak association between muscle mass and sexual desire 12 months after kidney transplantation was found (rS = 0.36, p = 0.02). Further, linear regression revealed that higher muscle mass could predict better sexual desire after kidney transplantation following adjustment for age, estimated glomerular filtration rate, and diabetes mellitus. Conclusions: Kidney transplantation did not significantly improve erectile dysfunction in our study population. Sexual desire and intercourse satisfaction are the most affected domains in patients with chronic kidney disease. Higher muscle mass predicts higher sexual desire after kidney transplantation. Higher levels of fat-free and lean mass are associated with normal erectile function before kidney transplantation.

What are the qualitative experiences of people affected by kidney failure receiving haemodialysis?

BACKGROUND

People affected by kidney failure receiving haemodialysis experience complexity within their health condition unlike any other chronic illness or condition. Kidney failure impacts the individual in all areas of their life including relationships and activities of daily living.

OBJECTIVE

To conduct a meta-aggregation of studies about the lived experiences of people with kidney failure receiving haemodialysis.

DESIGN

Using PRISMA Guidelines, six databases (CINAHL, ClinicalTrials.gov, Cochrane Library, MEDLINE, PsycINFO, and Scopus) were comprehensively searched using keywords and subject headings from January 1990 to October 2021. Articles were assessed according to prespecified eligibility criteria. Data extraction and quality appraisal was conducted. A meta-aggregation of qualitative findings was conducted using the Joanna Briggs Institute methodology for meta-aggregation.

RESULTS

Of the 9409 articles screened, 55 studies were included. This represented a total of 188 findings across 45 categories representing a range of unmet supportive care needs. The meta-aggregation identified 11 synthesised findings broadly related to psychological/emotional needs, physical needs, social needs, interpersonal/intimacy needs, patient-clinician communication needs, family related needs, health system/information needs, spiritual needs, daily living needs, practical needs and daily living needs.

CONCLUSIONS

This meta-aggregation has identified that people affected by kidney failure can experience a range of unmet supportive care needs. It was evident that living with kidney failure and receiving haemodialysis impacted a person's sense of self, introduced practical needs and other complex needs which were not being addressed in existing services. This review has highlighted important implications for clinical practice and future research directions.

Sexual function, depressive symptoms and quality of life of people undergoing hemodialysis therapy

Objective to analyze the correlation between sexual function, depressive symptomatology and quality of life of people on hemodialysis treatment. Method a cross-sectional study developed with 54 participants. Data collection occurred between the months of March and May 2020. The data were analyzed with the Mann-Whitney and Spearman Correlation tests, with a 95% confidence interval. Results the correlation between sexual function and depressive symptomatology was only clinically relevant for women (ρ= -0.724). Regarding quality of life, it was observed that the overall sexual function of men is negatively correlated with the pain dimension (ρ= -0.349) and with the social function (ρ= -0.347). For women, overall sexual function is positively correlated with physical function (ρ= 0.501), general health (ρ= 0.737), mental component (ρ= 0.497), sleep (ρ= 0.753), quality of social interaction (ρ= 0.621), and patient satisfaction (ρ= 0.457). Conclusion and implications for the practice increased sexual function was strongly correlated with reduced depressive symptoms and increased quality of life, implying the need to strengthen sexual approaches through protocols that provide referral flows to specialized trans-disciplinary teams.

RESUMO Objetivo analisar a correlação entre função sexual, sintomatologia depressiva e qualidade de vida de pessoas em tratamento hemodialítico. Método estudo transversal desenvolvido com 54 participantes. A coleta de dados ocorreu entre os meses de março a maio de 2020. Os dados foram analisados com os testes de Mann-Whitney e Correlação de Spearman, com intervalo de confiança de 95%. Resultados a correlação entre a função sexual e a sintomatologia depressiva somente foi clinicamente relevante para as mulheres (ρ= -0,724). Já em relação à qualidade de vida, observou-se que a função sexual geral dos homens está negativamente correlacionada com a dimensão dor (ρ= -0,349) e com a função social (ρ= -0,347). Já para as mulheres, a função sexual geral está positivamente correlacionada com a função física (ρ= 0,501), saúde geral (ρ= 0,737), componente mental (ρ= 0,497), sono (ρ= 0,753), qualidade da interação social (ρ= 0,621) e com a satisfação do paciente (ρ= 0,457). Conclusão e implicações para a prática o aumento da função sexual esteve fortemente correlacionado com a redução de sintomatologia depressiva e com o aumento da qualidade de vida, implicando a necessidade de fortalecer as abordagens sexuais por meio de protocolos que ofereçam fluxos de encaminhamento às equipes transdisciplinares especializadas.

Estimate the burden of sexual dysfunction due to non-communicable diseases in Ethiopia: Systematic review and meta-analysis

BACKGROUND

Untreated sexual dysfunction is a serious sexual problem that adversely affects the quality of life. Body of evidence indicates non-communicable diseases are common comorbid conditions associated with sexual dysfunction. Therefore, this review was aimed to synthesize and estimate the burden of sexual dysfunction and its determinant factors among patients with non-communicable diseases in Ethiopia.

METHODS

Cross-sectional studies were systematically searched using PubMed, Google Scholar, African Journals Online, Cochran Library, Scopus database, and gray literature. Data were extracted using a standardized Joanna Briggs Institute form. The I2 statistic was used to check heterogeneity across the included studies. A funnel plot and Egger's regression test were used to check the presence of publication bias. Sensitivity analysis was deployed to check the effect of a single study on the overall estimation. All statistical analyses were done using STATA version 11.0 software.

RESULT

A total of six studies with 2,434 study participants was included. The estimated pooled sexual dysfunction was 68.04% (95% CI: 56.41-79.67). Based on the subgroup analysis, the highest prevalence of sexual dysfunction was reported among patients with mental related illness, 73.02% (95% CI: 54.00-92.03).

CONCLUSION

In this review, nearly seven out of ten patients with chronic illness have sexual dysfunction, which implies sexual dysfunction was highly prevalent among non-communicable patients. Therefore, health care providers should screen and manage sexual dysfunction during follow-up for improving patient quality of life and sexual reproductive health satisfaction.

Sexuality in Kidney Transplant Recipients: A Qualitative Study

End-stage kidney disease has a negative impact on patients’ quality of life. People who receive a kidney transplant experience an improvement in many areas of their daily life. Sexuality is a general component of health, which can be affected by end-stage kidney disease and kidney transplant. The aim of this study was to explore and understand the experiences and perspectives of kidney transplant recipients regarding their sexuality. A qualitative study based on Gadamer’s hermeneutic philosophy was carried out. Two focus groups and nine interviews were conducted with 18 kidney transplant recipients. Data were audio-recorded, transcribed, and analyzed with the help of qualitative analysis software. Two main themes emerged from the data: (1) “The impact of a kidney transplant on sexuality”, with the subthemes “sexuality is relegated to the background”, “physical decline acts as a sexual inhibitor”, and “changes in sexual activity following a kidney transplant”; (2) “Sexual education in kidney transplant recipients” with the subthemes “sexuality: a hidden concern amongst kidney transplant recipients” and “talking about sexuality with healthcare professionals”. Sexuality is a frequent concern among kidney transplant recipients. The physiological and emotional changes experienced after kidney transplant exert a great influence on their sexuality. Healthcare professionals rarely discuss sexuality concerns with kidney transplant recipients. Professional sexual education and assistance are necessary to improve sexual health satisfaction of kidney transplant recipients.

Use of Sertraline in Hemodialysis Patients

Depression and anxiety are the most common psychiatric disorders in end-stage renal disease (ESRD) patients treated with hemodialysis (HD) and may correlate with lower quality of life and increased mortality. Depression treatment in HD patients is still a challenge both for nephrologists and psychiatrists. The possible treatment of depressive disorders can be pharmacological and non-pharmacological. In our article, we focus on the use of sertraline, the medication which seems to be relatively safe and efficient in the abovementioned population, taking under consideration several limitations regarding the use of other selective serotonin reuptake inhibitors (SSRIs). In our paper, we discuss different aspects of sertraline use, taking into consideration possible benefits and side effects of drug administration like impact on QTc (corrected QT interval) prolongation, intradialytic hypotension (IDH), chronic kidney disease-associated pruritus (CKD-aP), bleeding, sexual functions, inflammation, or fracture risk. Before administering the medication, one should consider benefits and possible side effects, which are particularly significant in the treatment of ESRD patients; this could help to optimize clinical outcomes. Sertraline seems to be safe in the HD population when provided in proper doses. However, we still need more studies in this field since the ones performed so far were usually based on small samples and lacked placebo control.

Multifaceted Sexual Dysfunction in Dialyzing Men and Women: Pathophysiology, Diagnostics, and Therapeutics

Patient survival continues to increase with the growing quality of dialysis and management of chronic kidney disease (CKD). As such, chronic therapy must include considerations of quality of life (QOL), and this includes the disproportionate prevalence of sexual dysfunction (SD) in this patient population. This review aims to describe the pathophysiological and the psychosocial causes of SD with regard to renal replacement therapy, particularly hemo- and peritoneal dialysis. The differences in its manifestation in men and women are compared, including hormonal imbalances—and therefore fertility, libido, and sexual satisfaction—the experience of depression and anxiety, and QOL. The impact of comorbidities and the iatrogenic causes of SD are described. This review also presents validated scales for screening and diagnosis of SD in CKD patients and outlines novel therapies and strategies for the effective management of SD. Increased prevalence of CKD invariably increases the number of patients with SD, and it is crucial for health care professional teams to become familiar with the clinical tools used to manage this sensitive and under-quantified field. As a known predictor of QOL, sexual function should become a point of focus in the pursuit of patient-centered care, particularly as we seek to achieve as “normal” a life as possible for individuals who receive dialysis.

Prevalence of Erectile Dysfunction in Patients With End-Stage Renal Disease: A Systematic Review and Meta-Analysis

BACKGROUND

Erectile dysfunction (ED) is an under-recognized clinical entity in men with end-stage renal disease (ESRD), and studies on renal transplant recipients, patients on dialysis, and patients starting dialysis report different prevalence rates and severity of ED among these groups.

AIM

To determine the prevalence and severity of ED in patients with ESRD, assessed with the International Index of Erectile Function-15 and International Index of Erectile Function-5.

METHODS

We performed a systematic review and meta-analysis of observational studies assessing the prevalence of ED in ESRD individuals. (PROSPERO ID: CRD42020182680). Records were identified by search in MEDLINE, Scopus, and CENTRAL databases and sources of gray literature until July 2020. We conducted a random-effects meta-analysis of proportions (double arcsine transformation).

OUTCOMES

We included 94 studies with 110 patient group entries and a total of 10,320 ESRD male individuals with a mean age of 48.8 ± 14.25 years.

RESULTS

Overall, 7,253 patients experienced ED. We estimated an overall pooled ED prevalence of 71% (95% CI: 67-74%, I² = 92%). In the subgroup analyses, the pooled prevalence was 59% (95% CI: 53-64%, I² = 92%) among renal transplant recipients, 79% (95% CI: 75-82%, I² = 86%) in patients on hemodialysis, 71% (95% CI: 58-83%, I² = 86%) in patients on peritoneal dialysis, and 82% (95% CI: 75-88%, I² = 0%) in patients with ESRD starting dialysis. The prevalence of the severity of ED was also estimated. Further assessment of heterogeneity was conducted via sensitivity analysis, cumulative meta-analysis, and meta-regression of significant risk factors.

CLINICAL TRANSLATION

Despite its high prevalence in patients with ESRD, ED constitutes an underestimated and taboo subject in this group. Therefore, arousing clinical concern among healthcare providers involved in ESRD management is more than necessary to screen and treat ED in patients receiving renal replacement therapy.

STRENGTHS & LIMITATIONS

We estimated ED solely for ESRD, included the largest number of patients compared with previous studies and estimated ED prevalence as per severity and renal replacement therapy subgroups. Contrary, because we restricted our eligibility criteria to the International Index of Erectile Function, some studies assessing ED prevalence with other validated tools were not included in this meta-analysis. Moreover, the levels of heterogeneity among studies remained high after sensitivity and meta-regression analyses, and for some moderators, the results of the meta-regression might have been underpowered.

CONCLUSIONS

ED is highly prevalent in patients with ESRD irrespective of the type of renal replacement therapy, thereby warranting clinical attention. Pyrgidis N, Mykoniatis I, Nigdelis MP, et al. Prevalence of Erectile Dysfunction in Patients With End-Stage Renal Disease: A Systematic Review and Meta-Analysis. J Sex Med 2021;18:113-120.
