Chronic liver diseases and erectile dysfunction

Sexual dysfunctions in patients with well-compensated chronic liver disease: role of etiology, Mediterranean diet and quality of life in an observational cross-sectional study

Background

Sexual dysfunctions (SD) are highly prevalent in Chronic Liver Diseases (CLD). Whether Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD) carries a higher risk of SD is unknown as is the role of dietary patterns or quality of Life (QoL).

Aim

to assess (1) prevalence of SD in CLD; (2) whether MASLD is a risk factor for SD; (3) the role of adherence to Mediterranean Diet (MD) or QoL.

Methods

Observational, cross-sectional study, 207 CLD patients (84 females and 123 males), median age 57 years (IQR:46-63); 96 (46.4%) MASLD; and 111 (53.6%) nonMASLD.

Outcomes

SD were assessed through Female Sexual Function Index (FSFI) and International Index of Erectile Function (IIEF) questionnaires. Adherence to MD was evaluated by the MD Score, QoL by SFHS-12 questionnaire evaluating physical [(ie, Physical Component Summary (PCS)] and mental [(ie, Mental Component Summary (MCS)] health. Multivariate analysis identified predictors of SD.

Results

(1) SD prevalence in CLD was 157/207 (75.8%); 80.9% females were at risk for SD, altered sexual desire/arousal and dyspareunia being the most common complaints, whereas 72.3% males had erectile dysfunction (ED); (2) prevalence of SD was higher in MASLD (89%) than in nonMASLD (64%) (P < 0.001); (3) in females, at univariate analysis, a negative correlation was found between FSFI and age, hypertension, or MASLD; (4) in males, at univariate analysis, IIEF-ED negatively correlated with age, DM2, or MASLD, whereas positively correlated with PCS and MCS; (5) in females, at multivariate analysis BMI (OR = 0.779,CI 95% = 0.640-0.948) and MCS (OR = 0.840,CI 95% = 0.741-0.953) were protective against SD, whereas age (OR = 1.115,CI 95% = 1.040-1.263) and DM2 (OR = 120.894,CI 95% = 1.396-10 741) were predictive of SD; (6) in males, at multivariate analysis, age (OR = 1088,CI 95% = 1032-1.148) and MASLD (OR = 4.075,CI 95% = 1.120-14.828) were risk factors for, whereas PCS (OR = 0,928,CI 95% = 0,865-0,995), and disease duration (OR = 0.393,CI 95% = 0.187-0.822) were protective against SD; 7) MD adherence, while higher in nonMASLD vs MASLD (P = 0.004), was not an independent protective factor against SD.

Clinical Implications

SD should not be underestimated in CLD patients, in particular those with MASLD.

Strengths and Limitations

Comprehensive study evaluating SD in a large cohort of CLD patients of both sexes, comparing MASLD vs nonMASLD. Due to its cross-sectional design, no conclusions can be drawn about cause and effect.

Conclusions

(1) CLD, in particular MASLD, have a high prevalence of SD which is not affected by MD adherence, whereas QoL seems to play a role; (2) CLD patients should be evaluated for SD, for early diagnosis and treatment.

Autophagy in erectile dysfunction: focusing on apoptosis and fibrosis

ABSTRACT

In most types of erectile dysfunction, particularly in advanced stages, typical pathological features observed are reduced parenchymal cells coupled with increased tissue fibrosis. However, the current treatment methods have shown limited success in reversing these pathologic changes. Recent research has revealed that changes in autophagy levels, along with alterations in apoptosis and fibrosis-related proteins, are linked to the progression of erectile dysfunction, suggesting a significant association. Autophagy, known to significantly affect cell fate and tissue fibrosis, is currently being explored as a potential treatment modality for erectile dysfunction. However, these present studies are still in their nascent stage, and there are limited experimental data available. This review analyzes erectile dysfunction from a pathological perspective. It provides an in-depth overview of how autophagy is involved in the apoptotic processes of smooth muscle and endothelial cells and its role in the fibrotic processes occurring in the cavernosum. This study aimed to develop a theoretical framework for the potential effectiveness of autophagy in preventing and treating erectile dysfunction, thus encouraging further investigation among researchers in this area.

Association between composite dietary antioxidant index and erectile dysfunction: a cross-sectional study from NHANES

BACKGROUND

Individual antioxidants may not fully capture the comprehensive antioxidant intake from an individual's diet. This study utilizes the Complex Dietary Antioxidant Index (CDAI) to evaluate the combined effects of various dietary antioxidants in the diet. The goal is to investigate the relationship between CDAI and the incidence of erectile dysfunction (ED), offering insights for dietary guidelines and intervention strategies aimed at mitigating the burden of ED.

METHODS

This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) database in the years 2001-2004. We employed a weighted multivariate logistic regression model to validate the relationship between CDAI and ED. Subgroup analyses were conducted to explore the correlation between CDAI and ED across different subgroups. Additionally, we used propensity score matching (PSM) to adjust for several key confounding variables, enhancing the robustness of the results.

RESULTS

In the fully adjusted multivariate logistic regression model for confounding variables, CDAI is negatively correlated with the risk of ED (OR = 0.95, 95% CI: 0.92-0.99, P = 0.005). When CDAI is transformed into a categorical variable based on quartiles, Q3 (OR = 0.73, 95% CI: 0.53-0.99, P = 0.040) and Q4 (OR = 0.70, 95% CI: 0.51-0.96, P = 0.026) show a negative correlation with the risk of ED. Subgroup analysis reveals no significant interaction. After adjusting for major confounding variables through PSM, the association between CDAI and reduced risk of ED remains significant.

CONCLUSION

In our study cohort, there is an association between CDAI and a reduced risk of ED, and further research is needed to validate and refine this conclusion.

Liver transplantation improves erectile function in patients with end-stage liver disease: a systematic review and meta-analysis

Background

Liver transplantation (LT) has been recognized as the most effective therapy for end-stage liver disease (ESLD). However, the question of whether LT can improve erectile function in patients with ESLD remains controversial. Therefore, we conducted this meta-analysis to evaluate the association between LT and erectile dysfunction (ED).

Methods

According to the PRISMA guidelines, studies were included after conducting searches in four databases from March 2024 onwards. These databases included PubMed, Cochrane Library, Web of Science, and Embase. The primary outcome of interest was to compare the International Index of Erectile Function (IIEF) scores between patients after and before LT. Standardized mean differences (SMDs) and their corresponding 95% confidence intervals (CIs) were utilized to assess the relationship between LT and ED.

Results

The results showed that the LT group had higher IIEF-5 domain scores for erectile function compared to the control group (SMD =-0.31, 95% CI: -0.53 to -0.09), P=0.007). No heterogeneity or publication bias was detected in the results. Additionally, the IIEF-15 domain score was also found to be improved after LT. Specifically, the LT group had higher domain scores for erectile function (SMD =-0.77, 95% CI: -1.07 to -0.48, P<0.001), orgasmic function (SMD =-0.82, 95% CI: -1.12 to -0.52, P<0.001), sexual desire (SMD =-0.89, 95% CI: -1.19 to -0.59, P<0.001), intercourse satisfaction (SMD =-0.92, 95% CI: -1.22 to -0.62, P<0.001), and overall satisfaction (SMD =-0.87, 95% CI: -1.17 to -0.57, P<0.001).

Conclusions

It is suggested by our meta-analysis that LT may contribute to improvements in erectile function among men with ESLD. This improvement may be related to the remarkable improvement in endocrine hormone disorders observed after LT. However, future studies with better designs and larger sample sizes are still needed to confirm our conclusions. Additionally, attention to erectile function before and after surgery in patients with liver failure is crucial.

Profound Sexual Dysfunction Among Patients with Hidradenitis Suppurativa: A Cross-sectional Study

INTRODUCTION

Sexual health, a critical aspect of overall well-being, is often compromised in individuals with chronic disorders. Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that mainly affects intertriginous areas, potentially impacting sexual health as a result of its specific symptoms and psychosocial burden.

METHODS

This cross-sectional study utilized data from the EpiCAi project, focusing on 199 patients with HS. Participants completed digital questionnaires assessing sexual health via sex-specific instruments: the Female Sexual Function Index (FSFI) for women and the International Index of Erectile Function (IIEF) for men, alongside different psychosocial scales. The disease severity was assessed using the Hurley stage and the Lesion Identification Scheme for Acne Inversa (LISAI).

RESULTS

The majority of the participants reported impaired sexual health, with significant clinical sexual dysfunctions noted in 71.8% of women (FSFI score < 26) and erectile dysfunction in 63.8% of men. Sexual dysfunction was associated with several factors, including age, and marital status. Psychosocial factors, notably depression and quality of life, showed strong correlations with sexual health outcomes. Notably, women over 40 and those treated with biologics reported more severe dysfunction, while among men, employment status significantly influenced sexual health.

CONCLUSIONS

HS profoundly affects the sexual health of both male and female patients, with significant impacts on their quality of life and psychological well-being. The findings underscore the necessity for healthcare providers to address sexual health proactively in the management of HS, considering both physical symptoms and psychosocial impacts. This holistic approach is essential for improving patient outcomes and overall quality of life.

Association between nonalcoholic fatty liver disease and erectile dysfunction among American Adults from the National Health and Nutrition Examination Survey: a cross-sectional study

Nonalcoholic fatty liver disease (NAFLD) is a pressing public health concern. NAFLD is recognized as a disease with systemic involvement. Erectile dysfunction is a prevalent condition among men. The study examined the relationship between NAFLD, assessed via U.S. Fatty Liver Index (USFLI), and erectile dysfunction. The study used cross-sectional data from the National Health and Nutrition Examination Survey conducted between 2001 and 2004 to examine the health of those over 20 years of age, collecting details on their erectile dysfunction, USFLI, and several other essential variables. A USFLI score equal to or exceeding 30 was chosen to diagnose NAFLD, while a USFLI score below 10 was utilized to exclude the presence of fatty liver. There were 3763 participants, with 29.1% (1095/3763) who experienced erectile dysfunction. After accounting for all potential covariates, USFLI was positively associated with erectile dysfunction (OR, 1.02; 95% CI, 1.02 ~ 1.03; P < 0.001). Compared with individuals with Q1 (USFLI < 10), the adjusted odds ratio values for USFLI and erectile dysfunction in Q2 (10 ≤ USFLI < 30) and Q3 (USFLI ≥ 30, NAFLD) were 1.84 (95% CI: 1.46 ~ 2.32, p < 0.001) and 2.18 (95% CI: 1.66 ~ 2.87, p < 0.001), respectively. The association USFLI and erectile dysfunction exhibited an L-shaped curve (nonlinear, P = 0.014). The odds ratio value of developing erectile dysfunction was 1.03 (95% CI: 1.021 ~ 1.04, P < 0.001) in participants with USFLI < 50.18. This study identified a positive correlation between USFLI and erectile dysfunction within the adult American population. Our findings imply that NAFLD might constitute an independent risk factor for erectile dysfunction.

The chronic alcohol consumption influences the gonadal axis in men: Results from a meta-analysis

BACKGROUND

Low testosterone concentrations affect 2-13% of adult males, with a direct association between reduction in testosterone (T) concentrations and cardiovascular events. Lifestyle habits have been linked to visceral fat accumulation and endocrine disorders like secondary hypogonadism. Alcohol intake has also been a topic of debate, with studies showing a detrimental effect on sperm production and underlying mechanisms. This meta-analysis aims to comprehensively evaluate the effect of alcohol consumption on T serum concentrations in adult men.

METHODS

The literature search included only controlled clinical trials comparing men who drink alcohol to men who do not, or who assumed placebo or nonalcoholic beverages. The primary outcome was the comparison of total testosterone serum concentrations between the study and control groups. The publications were examined for publication bias using Egger's test.

RESULTS

Twenty-one studies were included in the analysis for a total of 30 trials that examined the effects of alcohol consumption on testosterone level in 10,199 subjects. The meta-analysis showed that alcohol consumption overall is related to significant reduction in circulating concentrations of total testosterone (mean difference [MD] = -4.02; 95% CI -6.30, -1.73), free T (MD = -0.17; 95% CI -0.23, -0.12), sex hormone binding globulin (SHBG) (MD = -1.94; 95% CI -3.37, -0.48), an increase in estradiol (E2) (MD = 7.65; 95% CI 1.06, 14.23) and neutral effect on luteinizing hormone (LH) (MD = -0.15; 95% CI -0.36, 0.06), independently by age, body mass index (BMI), E2, and LH serum concentrations and alcohol intake. However, these results are evident only in healthy men exposed to chronic alcohol consumption and not in those with a recognized diagnosis of alcohol use disorder or after acute alcohol intake.

CONCLUSION

This study suggests how chronic alcohol consumption may inhibit the gonadal axis in healthy men, although the exact pathophysiological mechanisms connecting alcohol exposure and steroidogenesis are still not completely clarified.
