Prevalence and Associated Factors of Sexual Dysfunction in Patients With Inflammatory Bowel Disease

Impact of Chronic Medical Disease on Sexual Function and Other Conditions

Chronic diseases are prevalent and impact sexual health and function. Screening for and managing sexual dysfunction in women with chronic diseases is important to optimize well-being and quality of life. Clinicians should consider the biopsychosocial impact of chronic diseases on sexual health, screen for direct and indirect factors, and identify medications that may cause dysfunction. The authors recommend a multidisciplinary approach to treat sexual dysfunction in women with chronic diseases, including sexual medicine specialists, sex therapists, and pelvic floor physical therapists when indicated. This review provides a practical approach to assessing and managing sexual dysfunction in women with chronic diseases.

Association between bowel movement frequency and erectile dysfunction in patients with ulcerative colitis: a cross-sectional study

The association between ulcerative colitis (UC) and erectile dysfunction (ED) has been previously reported. Numerous previous studies have also reported an association between gastrointestinal symptoms and ED. Constipation and diarrhea are common in patients with UC. However, the specific association between bowel movement frequency and ED remains unclear. The aim of this study is to investigate the association between bowel movement frequency and ED in 164 patients with UC. The definition of ED, moderate to severe ED, and severe ED was the Sexual Health Inventory for Men score <22, <12, and <8, respectively. Bowel movement frequency was divided into three categories: (1) high (More than once a day), (2) normal (once a day, reference), and low (less than one time/day). The definition of constipation was based on the Rome I criteria and/or medication for constipation. The prevalence of constipation and ED was 10.4% and 86.0%, respectively. The rate of high, normal, and low bowel movement frequency was 56.1%, 25.0%, and 18.9%, respectively. High bowel movement frequency was independently and positively associated with ED and moderate to severe ED (ED: adjusted odds ratio [OR] 4.42, 95% confidence interval [CI] 1.35-15.98; moderate to severe: adjusted OR 2.98, 95% CI 1.22-7.61). Low bowel movement frequency was independently and positively associated with moderate to severe ED and severe ED (moderate to severe: adjusted OR 3.96, 95% CI 1.27-13.08; severe: adjusted OR 3.20, 95% CI 1.08-9.86). No association between constipation and ED was found. In conclusion, in Japanese patients with UC, both high and low bowel movement frequency were independently and positively associated with ED.

Prospective Evaluation of Sexual Dysfunction in Men With Chronic Pancreatitis: A Pilot Study

OBJECTIVE

Our study aimed to determine the prevalence of sexual dysfunction (SD) and its association with quality of life (QOL) in men with chronic pancreatitis (CP).

MATERIALS AND METHODS

Male patients with CP were prospectively enrolled in our pancreas center and completed the following 4 validated questionnaires: International Index of Erectile Function 5, Erectile Hardness Score, Pancreatitis Quality of Life Instrument, and Short Form Survey. Patients were classified as having mild, moderate, or severe SD based on review of questionnaires.

RESULTS

Thirty patients were enrolled in the study, of which 18 patients had SD (mild in 9, moderate in 1, and severe in 8 patients). No significant differences were seen demographic or clinical characteristics in patients with and without SD. Patients with SD had more abdominal pain compared with those without SD (94.4% vs 83.3%, P = 0.001). No significant differences were noted in QOL metrics between the 2 groups.

CONCLUSIONS

This pilot study shows that SD is present in 60% males with CP. No difference was noted in the QOL of patients with and without SD, albeit limited by our small sample size. Physicians caring for CP patients should routinely inquire for symptoms of SD and offer a urology referral if indicated.

Serum albumin levels as a useful complementary marker for erectile dysfunction in ulcerative colitis: A cross-sectional study

OBJECTIVE

Recently, a close association between ulcerative colitis (UC) and erectile dysfunction (ED) was reported. An inverse relationship between serum albumin and ED is found in patients with chronic disease. However, the association between serum albumin levels and ED in patients with UC is unclear. This study aims to investigate this issue in Japanese patients with UC.

METHODS

One hundred and thirty-six Japanese male UC patients were enrolled in this study. Information on serum albumin levels and medications for UC from medical records, Sexual Health Inventory for Men (SHIM) score information from self-administered questionnaires and information on the severity of UC from physician reports were obtained from medical records, self-administered questionnaires, and reports from physicians. The participants were divided into tertiles based on the total protein, serum globulin, serum albumin, aspartate aminotransferase, and C-reactive protein levels. The definition of ED and severe ED was SHIM score < 22 and SHIM score < 8, respectively. The association between these serum markers and ED was assessed by multivariate logistic regression.

RESULTS

The prevalence of severe ED in the low, moderate, and high albumin groups was 66.0%, 51.0%, and 28.3%, respectively. After adjusting for confounding factors, the low albumin group was independently and positively associated with severe ED (adjusted odds ratio: 2.74, 95% confidence interval: 1.03-7.48, p for trend =0.044). No association between other marker and ED was found.

CONCLUSION

Serum albumin was independently inversely associated with severe ED in Japanese patients with UC. Hypoalbuminemia might be a useful complementary marker for assessing the prevalence and severity of ED in UC patients.

A Mendelian randomization study on causal effects of inflammatory bowel disease on the risk of erectile dysfunction

This study aimed to evaluate the causal effects of inflammatory bowel disease (IBD) and erectile dysfunction (ED) using Mendelian randomization (MR). All datasets were obtained from the public genome-wide association study database. In the exposure group, 12,882 IBD patients and 21,770 controls were included. A total of 1154 ED patients and 94,024 controls were included in the outcome group. Two-sample MR was conducted to estimate the causal effect of IBD on ED. Furthermore, Crohn's disease (CD) and ulcerative colitis (UC) were exposure factors in subgroup analyses. Weighted median, MR-egger, Inverse-variant weighted (IVW), weighted mode, and simple mode methods were used in MR analysis. Horizontal pleiotropy test, heterogeneity test, and leave-one-out method were utilized to evaluate the sensitivity and stability of results. After analysis, 62, 52, and 36 single nucleotide polymorphisms (SNPs) that IBD-ED, CD-ED, and UC-ED were included, respectively. The incidence of ED was increased by IBD (IVW: OR = 1.110, 95% CI = 1.017-1.211, P = 0.019; P-heterogeneity > 0.05) and, in addition, ED was affected by CD (IVW: OR = 1.085, 95% CI = 1.015-1.160, P = 0.016; P-heterogeneity > 0.05). However, there was no causal effect of UC on ED (IVW: OR = 1.018, 95% CI = 0.917-1.129, P = 0.743; P-heterogeneity < 0.05). All SNPs showed no significant horizontal pleiotropy (P > 0.05). These results indicate that IBD and CD can cause ED; However, UC did not cause ED. Additional research was required to determine causality and potential mechanisms further.

Relationship between inflammatory bowel disease and erectile dysfunction: a 2-sample Mendelian randomization study

Background

Observational studies have indicated a high prevalence of erectile dysfunction (ED) among patients with inflammatory bowel disease (IBD), but a definitive causal relationship remains unestablished.

Aim

The primary aim of this study was to assess the potential causal relationship between IBD and ED using Mendelian randomization (MR) analysis.

Methods

We obtained statistical data for 2 subtypes of IBD, ulcerative colitis (UC) and Crohn's disease (CD), as well as for ED, from publicly available genome-wide association studies (GWASs). Subsequently, a 2-sample MR analysis was conducted using these datasets. The primary MR analysis utilized the inverse variance-weighted (IVW) method, complemented by secondary analyses employing MR-Egger and weighted median methods. Furthermore, we assessed heterogeneity using Cochran's Q test and evaluated pleiotropy with the MR-Egger intercept test. To identify potential influential single nucleotide polymorphisms, we employed a leave-one-out analysis. Additionally, outliers were identified using the MR-PRESSO method.

Outcomes

The study outcomes encompassed results from 3 MR analyses, namely IVW, MR-Egger, and weighted median, along with sensitivity analyses involving Cochran's Q test, the MR-Egger intercept test, leave-one-out analysis, and the MR-PRESSO method.

Results

There was no causal effect of UC and CD on ED in the MR analysis (IVW P > .05). Results of complementary methods were consistent with those of the IVW method. The results of sensitivity analyses supported our conclusion, and no directional pleiotropy was found.

Clinical Implications

Genetically, despite the absence of a causal link between IBD and ED according to MR analysis, we must emphasize the elevated ED prevalence among IBD patients in observational studies, with particular consideration for the influence of negative emotions on erectile function.

Strengths & Limitations

This study is the inaugural application of a 2-sample MR analysis using extensive GWAS datasets to evaluate the causal relationship between IBD and ED, effectively mitigating biases stemming from confounding factors and reverse causality often present in observational studies. Nevertheless, it is imperative to exercise caution when drawing conclusions due to inherent limitations in GWAS data, encompassing factors like samples overlap, gender categorization, population ancestry, and the persistent ambiguity surrounding the precise functionality of specific single nucleotide polymorphisms.

Conclusions

MR analysis did not provide genetic-level evidence supporting a direct causal relationship between IBD (UC and CD) and ED.

The prevalence and risk factors of sexual dysfunction among females with inflammatory bowel disease: a systematic review and meta-analysis

In recent years, numerous epidemiological studies have investigated the prevalence of female sexual dysfunction (FSD) in females with inflammatory bowel disease (IBD). However, a comprehensive systematic review with meta-analysis pooling their findings is lacking. This study aimed to determine the pooled prevalence estimates of FSD and its risk factors among females with IBD based on extensive research in electronic databases (PubMed, Embase, and Web of Science) from inception until April 1, 2023. The overall prevalence of FSD among females with IBD, along with its 95% confidence interval (CI), and subgroup-specific prevalence rates, were summarized. Sources of heterogeneity were identified through subgroup analyses and meta-regression. A total of 13 studies were included in this systematic review and meta-analysis. The pooled global prevalence of FSD among females with IBD was 61.4% (95% CI: 52.8-70.1%). Sensitivity analysis, which involved excluding individual studies, indicated no significant variation in the pooled prevalence, confirming the robustness of our results. Additionally, a significant risk factor for FSD among females with IBD was the quality of life (OR = 0.39, 95% CI: 0.19-0.79). In conclusion, our systematic review and meta-analysis revealed a high prevalence of FSD among females with IBD, which warrants attention from health organizations and clinical practitioners. Importantly, the quality of life was identified as a potential risk factor for FSD in this population. Nonetheless, future prospective cohort studies with a large sample size are warranted to confirm these findings.

Depressive and Anxiety Disorders in Patients with Inflammatory Bowel Diseases: Are There Any Gender Differences?

Gender differences were identified in the frequency and clinical presentations of inflammatory bowel disease (IBD) and depressive and anxiety disorders, which are more common in IBD patients than in the general population. The present manuscript provides a critical overview of gender differences in the frequency and clinical course of mood and anxiety disorders in IBD patients, with the aim of helping clinicians provide individualized management for patients. All of the included studies found that IBD patients reported a higher frequency of depressive and anxiety disorders than the general population. These findings should encourage healthcare providers to employ validated tools to monitor the mental health of their IBD patients, such as the Patient Health Questionnaire (PHQ-9). In addition, most studies confirm that women with IBD are more likely than men to develop affective disorders and show that up to 65% of women with IBD have depressive and anxiety disorders. Women with IBD require close mental health monitoring and ultimately a multidisciplinary approach involving mental health professionals. Drug treatment in women should be individualized and medications that may affect mental health (e.g., corticosteroids) should be thoroughly reconsidered. Further data are needed to ensure individualized treatment for IBD patients in a framework of precision medicine.

Disease activity and erectile dysfunction in Japanese patients with ulcerative colitis

Background

The association between disease activity and erectile dysfunction (ED) in patients with inflammatory bowel disease (IBD) is inconsistent, although IBD, including ulcerative colitis (UC), is reported as a risk factor for ED.

Aim

The purpose of this study was to explore this association in Japanese patients with UC.

Methods

In this study, we enrolled 165 Japanese male patients with UC. Information regarding the Sexual Health Inventory for Men (SHIM) score, medication, and severity of UC was obtained from medical records, self-administered questionnaires, and reports from physicians. The definition of ED and severe ED is a SHIM score <17 and <8, respectively.

Outcomes

No association between severity of UC and ED was found in Japanese patients. Aging is independently positively associated with ED in patients with UC.

Results

The prevalence of severe ED and ED was 47.9% and 64.9%, respectively. In this study, mucosal healing, clinical remission, duration of UC, disease extent, and medication were not associated with the prevalence of ED. Older age (≥63 years of age) was independently positively associated with ED (adjusted odds ratio, 12.93; 95% CI: 4.51-43.00) and severe ED (adjusted odds ratio, 9.02; 95% CI: 3.66-23.91).

Clinical Implications

Disease severity of UC might not be associated with the prevalence of ED in patients with UC.

Strengths and Limitations

This is the first study to investigate the association between several factors regarding UC activity and ED. The limitation of this study is the definition of ED based on SHIM scores.

Conclusion

No association between severity of UC and ED was found in Japanese patients. As expected, aging may be independently positively associated with ED in patients with UC.

“Adipose-derived mesenchymal stem cell therapy for the management of female sexual dysfunction: Literature reviews and study design of a clinical trial”

Hormone imbalance and female sexual dysfunction immensely affect perimenopausal female health and quality of life. Hormone therapy can improve female hormone deficiency, but long-term use increases the risk of cardiovascular diseases and cancer. Therefore, it is necessary to develop a novel effective treatment to achieve long-term improvement in female general and sexual health. This study reviewed factors affecting syndromes of female sexual dysfunction and its current therapy options. Next, the authors introduced research data on mesenchymal stromal cell/mesenchymal stem cell (MSC) therapy to treat female reproductive diseases, including Asherman’s syndrome, premature ovarian failure/primary ovarian insufficiency, and vaginal atrophy. Among adult tissue-derived MSCs, adipose tissue-derived stem cells (ASCs) have emerged as the most potent therapeutic cell therapy due to their abundant presence in the stromal vascular fraction of fat, high proliferation capacity, superior immunomodulation, and strong secretion profile of regenerative factors. Potential mechanisms and side effects of ASCs for the treatment of female sexual dysfunction will be discussed. Our phase I clinical trial has demonstrated the safety of autologous ASC therapy for women and men with sexual hormone deficiency. We designed the first randomized controlled crossover phase II trial to investigate the safety and efficacy of autologous ASCs to treat female sexual dysfunction in perimenopausal women. Here, we introduce the rationale, trial design, and methodology of this clinical study. Because aging and metabolic diseases negatively impact the bioactivity of adult-derived MSCs, this study will use ASCs cultured in physiological oxygen tension (5%) to cope with these challenges. A total of 130 perimenopausal women with sexual dysfunction will receive two intravenous infusions of autologous ASCs in a crossover design. The aims of the proposed study are to evaluate 1) the safety of cell infusion based on the frequency and severity of adverse events/serious adverse events during infusion and follow-up and 2) improvements in female sexual function assessed by the Female Sexual Function Index (FSFI), the Utian Quality of Life Scale (UQOL), and the levels of follicle-stimulating hormone (FSH) and estradiol. In addition, cellular aging biomarkers, including plasminogen activator inhibitor-1 (PAI-1), p16 and p21 expression in T cells and the inflammatory cytokine profile, will also be characterized. Overall, this study will provide essential insights into the effects and potential mechanisms of ASC therapy for perimenopausal women with sexual dysfunction. It also suggests direction and design strategies for future research.
