Male Sexual Function in Patients Receiving Different Types of Renal Replacement Therapy

Significant Increase of Sexual Dysfunction in Patients With Renal Failure Receiving Renal Replacement Therapy: A Systematic Review and Meta-Analysis

BACKGROUND

It has been shown that sexual dysfunction (SD) is highly prevalent among patients with chronic renal failure (CRF), and starting renal replacement therapy may even increase it. However, SD is an infrequently reported problem in these treated patients.

AIM

To investigate the prevalence of SD among patients with CRF undergoing renal replacement therapy, by a meta-analysis method.

METHODS

PubMed, Embase, and the Cochrane Library were systematically searched for all studies assessing sexual function in patients with CRF receiving renal replacement therapy from January 2000 to April 2020. Relative risk (RR) with 95% CIs was used for analysis to assess the risk of SD in patients with CRF receiving renal replacement therapy. The cross-sectional study quality methodology checklist was used for the cross-sectional study. The methodologic quality of the case-control and cohort studies was assessed with the Newcastle-Ottawa Scale. Data were pooled for the random-effect model. Sensitivity analyses were conducted to assess potential bias. The Begg and Egger tests were used for publication bias analysis.

OUTCOMES

The prevalence of SD among patients with CRF receiving renal replacement therapy was summarized using pooled RR and 95% CI.

RESULTS

This meta-analysis included 3,725 participants from 10 studies. Of these, 737 were patients with CRF receiving renal replacement therapy. The mean age of participants ranged from 32.75 to 56.1 years. Based on the random-effect model, synthesis of results demonstrated that the prevalence of SD was significantly increased among patients with CRF receiving renal replacement therapy in women (RR = 2.07, 95% CI: 1.47-2.91, P = .000; heterogeneity: I² = 78.7%, P = .000) and in men (RR = 2.95, 95% CI: 2.16-4.02, P = .000; heterogeneity: I² = 86.1%, P = .000). Estimates of the total effects were generally consistent in the sensitivity analysis. No evidence of publication bias was observed.

CLINICAL IMPLICATIONS

Patients with CRF receiving renal replacement therapy had a significantly increased risk of SD, which suggests that clinicians should evaluate sexual function, when managing patients with CRF receiving renal replacement therapy.

STRENGTHS AND LIMITATIONS

This is the first study to explore the prevalence of SD among patients with CRF undergoing renal replacement therapy based on all available epidemiologic studies. However, all included studies were an observational design, which may downgrade this evidence.

CONCLUSION

The prevalence of SD is significantly increased among patients with CRF receiving renal replacement therapy. More research studies are warranted to clarify the relationship.

Erectile function after kidney transplantation: a meta-analysis

Background

Erectile dysfunction (ED) is common in patients with end-stage renal disease (ESRD). Whether kidney transplantation can improve erectile function in patients with ESRD is still controversial. We conducted a meta-analysis on the relationship between kidney transplantation and erectile function.

Methods

A literature search was conducted on PubMed, Embase, Cochrane Library, and Web of Science until May 31, 2019. Primary outcomes were ED prevalence and each domain score of the International Index of Erectile Function (IIEF) questionnaire. We used age-matched dialysis patients or patients before kidney transplantation as a control group and compared them to kidney transplant recipients.

Results

A total of 9 articles were finally enrolled in the study. Compared with the control group, the kidney transplantation group had a lower prevalence of ED (OR 0.49, 95% CI: 0.28–0.86) and higher domain scores for erectile function (SMD 0.53, 95% CI: 0.12–0.94) and sexual desire (SMD 1.19, 95% CI: 0.11–2.27). While there were no significant variations in domain scores for orgasmic function (SMD 0.27, 95% CI: −0.10–0.63), intercourse satisfaction (SMD 0.26, 95% CI: −0.10–0.61), and overall satisfaction (SMD 0.17, 95% CI: −0.21–0.56). Patients in the kidney transplantation group had higher serum testosterone (SMD 1.20, 95% CI: 0.86–1.54) and lower prolactin (SMD −1.46, 95% CI: −2.22 to −0.69) and luteinizing hormone (SMD −0.97, 95% CI: −1.39 to −0.55).

Conclusions

Kidney transplantation may be associated with improved erectile function in patients with ESRD. This may be attributable to the correction of endocrine hormone disorders in patients after kidney transplantation.

Adaptation Process of Male Kidney Transplant Recipients During the Difficult Postoperative Recovery Stage at Home

BACKGROUND

Kidney transplantation is the main treatment for irreversible organ failure. It helps patients regain hope, prolongs their lives, and improves their quality of life. Because of cultural barriers, male kidney-transplant recipients in Taiwan may face a difficult adaptation process during postoperative care at home.

METHODS

In this qualitative exploratory study, we employed purposive sampling of male kidney-transplant recipients that was obtained from a leading medical center in Taiwan. Semi-structured, face-to-face interviews were used to collect data, which were further content analyzed.

RESULTS

All 30 qualified patients were approached and agreed to participate (age range = 29-67 years). Participants' post-kidney transplant time frame ranged from 2 to 22 years. We revealed several difficulties that participants experienced during their postoperative recovery: (1) physical and mental exhaustion and treatment side effects; (2) worry and uncertainty about rejection, graft failure, and the future; (3) fear of losing one's job and putting the family in financial trouble; and (4) impaired self-image and social barriers. Corresponding adaptation processes included (1) experiencing shock during the early post-transplantation stage, (2) re-identification of the transition period of self-value, (3) seeking support and thinking positively, (4) accepting one's new self-image, and (5) regaining autonomy.

CONCLUSION

The current results can be used to improve the quality of care at home for male kidney-transplant recipients. Health care providers should assist patients in the adaptation process to reduce discomfort and relieve stress. This study can also serve as a reference for future research.

Male Sexual Function After Pediatric Kidney Transplantation-A Cross-sectional Nationwide Study

BACKGROUND

Data on adult sexual functioning after kidney transplantation (KTx) during childhood or adolescence are scarce.

AIM

To assess the long-term sexual and psychosocial quality of life after pediatric KTx.

METHODS

29 young men (median age 27.1 years) were examined 18.7 years (median) after KTx. 56 age-matched healthy men (median age 30.0 years) served as controls.

OUTCOME

We studied the influence of sociodemographics, previous renal replacement therapy, current reproductive hormonal serum levels, testicular size, and data on several validated mental and physical questionnaires on participants' Derogatis Interview for Sexual Functioning self-report scores.

RESULTS

The KTx recipients had significantly poorer sexual functioning than their healthy peers. KTx men had less frequent sexual activity with a partner (P = .03) and poorer orgasms (P = .002) than the controls but no erectile dysfunction (P = .5).

CLINICAL IMPLICATIONS

Depressive symptoms, relationship status, and longer dialysis duration predicted poor adult sexual functioning in KTx recipients, whereas age at transplantation or at the time of the study did not.

STRENGTHS & LIMITATIONS

This study contributes extended follow-up data to the very scarce literature on adult sexual functioning in pediatric KTx recipients. Relatively small population and low participation rate limit the comprehensive data interpretation in a population-based cohort of male KTx recipients.

CONCLUSION

Sexual functioning is often impaired in young men after pediatric KTx, emphasizing the need for long-term monitoring of sexual health and sexuality as important dimensions of quality of life.

Is dialysis adequacy a useful predictor for sexual function in males and females with end-stage renal disease?

INTRODUCTION

The development of sexual dysfunction (SD) in dialysis patients is multifactorial. We aimed to evaluate whether adequate dialysis had an effect on the development of SD in male and female patients undergoing dialysis due to end stage renal disease. Anxiety, depression, health-related quality of life and the other risk factors related to dialysis were also evaluated in terms of SD.

METHODS

Seventy men and 57 women undergoing haemodialysis (HD) or peritoneal dialysis (PD) and 65 healthy male volunteers and 48 healthy female volunteers, age-matched, were included in the study. The International Index of Erectile Function, Female Sexual Function Index, Beck Depression Inventory, Beck Anxiety Inventory and The Short Form-36 Health Survey were applied to all participants. The cut off value of Kt/V was determined as 1.3 for HD and 1.7 for PD to assess dialysis adequacy. Per gender, all the participants were divided into three groups as control, adequate dialysis and non-adequate dialysis.

RESULTS

Dialysis adequacy [OR: 3.225, 95%CI (1.213-8.620), p=.019] was found as a more decisive factor for male SD, while dialysis adequacy [OR: 3.015, 95%CI (.991-7.250), p=.041] and depression [OR: 4.280, 95%CI (1.705-10.747), p=.002] were more significant for female SD. In addition, a strong relationship was found between male SD and physical functioning (r: .524, p=.032), social functioning (r: .565, p=.042), general health (r: .693, p=.037) perception, while female SD was found to be strongly associated with anxiety (r: -.697, p=.002) and depression (r: -.738, p=.001).

DISCUSSION

Dialysis adequacy was found to be the most important factor in reducing SD. Non-adequate dialysis resulted in worse sexual function, higher levels of depression and anxiety. Its negative effect on health-related quality of life was only seen in men.

[Sexual disorders in the renal patient]

Quality of Life Related to Health is currently considered one of the primary therapeutic objectives in renal failure patients who need substitution treatment as life prolonging therapy. Sexual health is a basic right that positively affects the quality of life. Although a significant percentage of chronic patients have some type of sexual dysfunction, this is not openly discussed, making it important for doctors to address these issues in the clinic. A review is presented on the pathophysiology of sexual dysfunctions in both male and female chronic renal patients. The effects of dialysis and transplantation on sexual function will be addressed, as well as presenting the main sexual dysfunctions and their treatment.

Sexual dysfunctions and related variables with sexual function in patients who undergo dialysis for chronic renal failure

AIMS AND OBJECTIVES

To evaluate personality characteristics and psychological symptoms believed to have an effect on the sexual functions and performances of patients undergoing dialysis treatment.

BACKGROUND

Chronic renal failure is a life-threatening condition which can often have a poor prognosis. The loss of vital kidney function and other complications can affect almost all age groups.

DESIGN

A quantitative descriptive study.

METHODS

The study sample included 225 patients selected randomly from patients who have undergone dialysis treatment for at least 3 months at a dialysis centre in a university hospital. In this study, the Golombok Rust Inventory of Sexual Satisfaction (GRISS), the Eysenck Personality Inventory (EPI) and the Brief Symptom Inventory (BSI) were used.

RESULTS

In the correlation test, made to investigate the relation between the patients' sexual satisfaction and their personalities, a significant positive relation was found between the communication subscale of the GRISS and the Lie dimension of the EPI, and a significant negative relation was found between the Communication subscale of the GRISS and the Lie dimension of the EPI, and between the Vaginismus and Orgasm subscales of the GRISS and the Extroversion dimension of the EPI.

CONCLUSION

Results showed that sexual problems, in the areas of nonsensuality, anorgasmia, avoidance and communication, are associated with extroversion and psychological symptoms.

RELEVANCE TO CLINICAL PRACTICE

Sexual health and the psychological well-being of patients with renal failure is an important issue that should be considered in nursing practice. Nurses should take the psychological problems of patients and their relations with partners into account and consider these problems in a holistic manner within the framework of nursing practice. They would then be able to play an effective role in intervening at an early stage and would be better equipped to help and control the psychological and sexual problems that some patients may experience.

Erectile Dysfunction and Depression: A Systematic Review and Meta-Analysis

BACKGROUND

Some studies have reported that exposure to depression increases the risk of erectile dysfunction (ED), whereas others have observed no association. Moreover, additional studies have reported that exposure to ED increases the risk of depression.

AIM

To identify and quantitatively synthesize all studies evaluating the association between ED and depression and to explore factors that may explain differences in the observed association.

METHODS

We conducted a systematic review and meta-analysis. We searched Medline, Ovid Embase, and the Cochrane Library through October 2017 for studies that had evaluated the association between ED and depression. Studies were included in accordance with Patient Population or Problem, Intervention, Comparison, Outcomes, and Setting (PICOS) inclusion criteria.

OUTCOMES

The odds ratio (OR) was regarded as the effect size, and the heterogeneity across studies was assessed using the I² statistic.

RESULTS

We identified 49 eligible publications. The pooled OR for studies evaluating depression exposure and risk of ED was 1.39 (95% CI: 1.35-1.42; n = 46 publications with 48 studies). Although we observed large heterogeneity (I² = 93.6%), subgroup analysis indicated that it may have been as a result of variations in study design, comorbidities, ED assessment, depression assessment, the source of the original effect size, etc. No significant publication bias was observed (P = .315), and the overall effect size did not change by excluding any single study. The pooled OR for studies evaluating ED exposure and risk of depression was 2.92 (95% CI: 2.37-3.60; n = 5 publications with 6 studies). No significant heterogeneity (P < .257, I² = 23.5%) or publication bias (P = .260) was observed.

CLINICAL IMPLICATIONS

Patients reporting ED should be routinely screened for depression, whereas patients presenting with symptoms of depression should be routinely assessed for ED.

STRENGTHS AND LIMITATIONS

There are several strengths to this study. First, evaluations of the association between ED and depression are timely and relevant for clinicians, policymakers, and patients. Second, we intentionally conducted 2 meta-analyses on the association, allowing us to include all potentially relevant studies. However, our study also possesses some limitations. First, the OR is a measure of association that only reveals whether an association is present. Thus, this study was unable to determine the direction of causality between ED and depression. Second, the high heterogeneity among studies makes it difficult to generalize the conclusions.

CONCLUSION

This study demonstrates an association between depression and ED. Policymakers, clinicians and patients should attend to the association between depression and ED. Liu Q, Zhang Y, Wang J, et al.

Development and Psychometric Testing of a Sexual Concerns Questionnaire for Kidney Transplant Recipients

BACKGROUND AND PURPOSE

This study describes the development and psychometric testing of the Sexual Concerns Questionnaire (SCQ) in kidney transplant (KTx) recipients.

METHODS

Construct validity was assessed using the Kroonenberg and Lewis exploratory/confirmatory procedure and testing hypothesized relationships with established questionnaires. Configural and weak invariance were examined across gender, dialysis history, relationship status, and transplant type. Reliability was assessed with Cronbach's alpha, composite reliability, and test-retest reliability.

RESULTS

Factor analysis resulted in a 7-factor solution and suggests good model fit. Construct validity was also supported by the tests of hypothesized relationships. Configural and weak invariance were supported for all subgroups. Reliability of the SCQ was also supported.

CONCLUSIONS

Findings indicate the SCQ is a valid and reliable measure of KTx recipients' sexual concerns.

Prevalence of subnormal testosterone concentrations in men with type 2 diabetes and chronic kidney disease

BACKGROUND

One-third of men with type 2 diabetes have subnormal testosterone concentrations along with inappropriately normal LH and FSH concentrations. It is not known if the presence of renal insufficiency affects free testosterone concentrations in men with type 2 diabetes.

HYPOTHESIS

We hypothesized that type 2 diabetic men with chronic renal disease (CKD; estimated glomerular filtration rate (eGFR) < 60 ml/min per 1.73 m(2)) have lower free testosterone concentrations than men with normal renal function (eGFR ≥ 60 ml/min per 1.73 m(2)).

STUDY DESIGN AND SETTING

This is a retrospective chart review of patients attending diabetes and nephrology clinics. Men with type 2 diabetes who had the following information available were included in the study: testosterone (total and free) done by LC/MS-MS followed by equilibrium dialysis, sex hormone binding globulin, LH, FSH and prolactin concentrations.

PARTICIPANTS

We present data on T and gonadotropin concentrations in 111 men with type 2 diabetes and CKD (stages 3-5) and 182 type 2 diabetic men without CKD.

RESULTS

The prevalence of subnormal free testosterone concentrations was higher in men with type 2 diabetes and CKD as compared to those without CKD (66% vs 37%, P < 0.001). Men with CKD had a higher prevalence of hypergonadotropic hypogonadism (26% vs 5%, P < 0.001) but not of hypogonadotropic hypogonadism (HH; 40% vs 32%, P = 0.22). There was an increase in the prevalence of hypergonadotropic hypogonadism with decreasing eGFR. Fifty-two percent of men with renal failure (CKD stage 5) had hypergonadotropic hypogonadism and 25% had HH. In men with CKD, the hemoglobin concentrations were lower in those with subnormal free T concentrations as compared to men with normal free T concentrations (119 ± 19 vs 128 ± 19 g/l, P = 0.04).

CONCLUSIONS

Two-thirds of men with type 2 diabetes and CKD have subnormal free T concentrations. The hypogonadism associated with CKD is predominantly hypergonadotropic.

Sexual function in patients supported with left ventricular assist device and with heart transplant

AIMS

Sexual dysfunction is common among patients with heart failure (HF) and considered an important hamper to quality of life. While implantation of left ventricular assist device (LVAD) may prolong and improve life in advanced HF, limited data are available on its impact on sexual function. The aim of this study is to evaluate sexual function in LVAD patients and compare this with patients after heart transplantation (HTx).

METHODS AND RESULTS

Sexual activity and satisfaction of stable patients with durable LVAD or after HTx were evaluated using a validated questionnaire and visual analogue scale from 0 to 10. Data were collected from 31 patients (mean age 59 ± 12 years, 87% male), 17 after HTx and 14 with LVAD. Pleasure or satisfaction with sex was significantly higher in HTx patients (P = 0.0005). In total, 29% LVAD patients and 71% HTx patients reported content with sexual activity. Recalled satisfaction with sex life pre-operation was comparable between the groups. During support, satisfaction with sex life using visual analogue scale was 7.6 ± 3.1 for HTx versus 3.9 ± 4.0 for LVAD patients (P = 0.017). In total, 11 LVAD patients (79%) reported specific problems in sexual function including erectile dysfunction or vaginal dryness (8, 57%); problems with the LVAD, cable, or batteries (5, 36%); problems with orgasm (4,29%); and other problems such as fear of injury, feeling depressed, partner issues, self-image, and pain (1, 7% each).

CONCLUSION

Sexual dysfunction occurs in patients with LVAD support and may be more prominent than after HTx. Problems limiting sexual function related to physiological, psychological, and equipment merit consideration during follow-up.
