Prevalence and risk factors of erectile dysfunction in patients with hepatitis B virus or hepatitis C virus or chronic liver disease: results from a prospective study

PDE5is-naïve versus non-naïve patients at first investigation for erectile dysfunction-findings from a long-term, real-life cross-sectional study

BACKGROUND

Phosphodiesterase 5 inhibitors (PDE5is) represent a first-line pharmacological therapy for erectile dysfunction (ED). Men could obtain PDE5is for recreational purposes without any proper medical prescription.

OBJECTIVE

We aimed to analyze clinical characteristics of patients who already used any PDE5i for ED without previous formal medical prescription.

MATERIALS AND METHODS

Data from 2012 heterosexual, sexually active men seeking first medical help for ED at our outpatient clinic between 2005 and 2022 were analyzed. All patients were assessed with a comprehensive sexual and medical history and completed the International Index of Erectile Function (IIEF) at baseline. Comorbidities were scored with the Charlson comorbidity index (CCI). Thereof, according to exposure to any PDE5i before their first visit, patients were subdivided into: PDE5i-naïve and non-PDE5i-naïve patients. Descriptive statistics tested the sociodemographic and clinical characteristics of both groups. A logistic regression model predicted the likelihood of being PDE5i-naïve at the baseline. Linear regression analysis (LRA) estimated the likelihood of being PDE5i-naïve versus non-PDE5i-naïve over the analyzed timeframe. Lastly, local polynomial regression models graphically explored the likelihood of being PDE5i-naïve at the first clinical assessment over the analyzed timeframe, and the sensitivity analyses tested the probability of being PDE5i-naïve at baseline.

RESULTS

Overall, 1,491 (70.9%) patients were PDE5i-naïve and 611 (29.1%) were non-PDE5i-naïve at the first assessment. PDE5is-naïve patients were younger, with a lower prevalence of CCI ≥ 1 and of normal erectile function (EF) than non-PDE5i-naïve men (all p < 0.05). Multivariable logistic regression found that patients with lower BMI (OR: 0.99), higher IIEF-EF scores (OR: 1.02), lower rates of severe ED (OR: 0.94), and who had been assessed earlier throughout the study timeframe (OR: 1.27) were less likely to be PDE5i-naïve at baseline. Univariate LRA revealed that younger patients (Coeff: -0.02), with lower CCI (Coeff: -0.29) and higher alcohol intake per week (Coeff: 0.52) were more likely to be PDE5i-naïve over the analyzed timeframe. Moreover, for the same IIEF-EF score, patients with higher CCI had lower probability of being PDE5i-naïve.

CONCLUSIONS

Self-prescription of PDE5is is an attitude presents in the general population, despite this phenomenon has decreased overtime. Current data outline the importance to keep promoting educational campaigns to promote PDE5is as effective and safe medicinal products, while avoiding their improper use.

Prevalence and predictors of unrecognised low sexual desire/interest in men with new onset erectile dysfunction: findings from a cross-sectional, real-life study

The interrelationship between male sexual desire and erectile dysfunction (ED) has been scantly investigated. Thus, we aimed at investigating the prevalence of and the predictors of unrecognised low sexual desire/interest (uLSD/I) in a cohort of men with new onset ED. Complete data from 1587 men seeking for first medical help for ED between 2010 and 2021 were analysed. Comorbidities were scored with the Charlson Comorbidity Index (CCI). At entrance, all patients were asked to self-report low sexual desire/interest and completed the International Index of Erectile Function (IIEF) and the Beck Depression Inventory (BDI) (depressive symptoms scored as BDI ≥ 11). The IIEF-erectile function (IIEF-EF) domain was categorised according to Cappelleri's criteria. The median value of the IIEF-sexual desire domain (IIEF-SD) was used to dichotomise men with uLSD/I along with ED (IIEF-SD < 7) vs. ED-only (IIEF-SD ≥ 7). Circulating hormones were measured in every patient. Hypogonadism was defined as total testosterone (tT) <3.0 ng/mL. Descriptive statistics and logistic regression models tested the association between clinical variables and uLSD/I. Of 1197 patients not self-reporting LSD/I, 369 (30.8%) had IIEF-SD < 7. Patients with ED + uLSD/I were older [median (IQR) 54(41-63) vs. 49(36-59) years], had lower IIEF-EF [10.5(5-22) vs. 22(11-28)] but higher BDI [6(3-12) vs. 4(1-8)] and lower tT [4.3(3.2-5.7) vs. 4.8(3.2-6.3) ng/mL] compared to ED-only men (all p < 0.05). Overall, ED + uLSD/I men had higher rate of severe ED (49.9% vs. 23.9%), and of BDI ≥ 11 (30.6% vs. 18.2%) (all p < 0.05). At multivariable logistic regression analysis, lower tT (OR: 0.82), lower IIEF-EF scores (OR:0.95) and BDI ≥ 11 (OR:2.51) were independently associated with ED + uLSD/I, after accounting for age (all p < 0.05). Almost 30% of men seeking first medical help for ED-only had also uLSD/I. Men with both conditions were older, had higher rates of severe ED and more depressive symptoms. A detailed investigation of sexual desire should be always included in men self-complaining only of ED.

Premature ejaculation among men with erectile dysfunction-findings from a real-life cross-sectional study

Concomitant sexual disorders have progressively shown increased prevalence in men at first outpatient presentation. We sought to i) estimate the prevalence of unreported premature ejaculation (PE) in a homogenous cohort of 1258 men seeking first medical help for erectile dysfunction (ED) as their primary compliant; ii) compare the baseline sociodemographic and clinical characteristics of men with only ED(ED-only) compared to those with ED and PE(ED + PE); and, iii) investigate the likelihood of detecting PE among men self-reporting only ED over a 16-year period at a single tertiary-referral centre. Descriptive statistics compared sociodemographic and clinical characteristics between ED-only patients and those with unreported concomitant primary/secondary PE(ED + PE). Logistic regression models predicted the risk of having ED + PE at baseline. Local polynomial regression models graphically explored the probability of reporting PE among ED men with ≤40 vs. 41-60 vs. >60 years over the analysed timeframe. Of all, 932 (74.1%) were ED-only and 326 (25.9%) ED + PE patients, respectively. ED + PE patients were younger, presented with fewer comorbidities, and lower rates of severe ED (all p ≤ 0.04). At multivariable logistic regression analysis, younger age (OR:0.98) and low sexual desire/interest (OR:1.54) were independently associated with ED + PE at first clinical assessment (all p = 0.03). The likelihood of detecting unreported concomitant primary/secondary PE among patients complaining of only ED at first presentation worrisomely increased among younger and middle-aged men over the last 16 years.

Microbiota and hepatitis C virus in the era of direct-acting antiviral agents

The gut microbiota plays a fundamental role in Hepatitis C Virus (HCV)-related liver disease. Indeed, HCV infection alters the gut microbiota, whereas intestinal dysbiosis induces an underlying inflammatory state. This status may lead to liver disease progression. The advent of direct acting antivirals (DAAs) was a turning point in the history of HCV infection, which enhances the chances of recovery. Beyond the elimination of the virus, DAA therapy can affect the gut microbiota of the HCV patient. The study of the gut microbiota in the patient with HCV-related liver disease could be the first step in understanding the etiopathogenesis of hepatopathy thereby opening the way to new therapeutic opportunities. Herein we evaluate current knowledge regarding the gut microbiota in patients with HCV infection and the impact of DAA therapy.

Chronic liver diseases and erectile dysfunction

Chronic liver diseases (CLDs) are characterized by progressive necrosis of hepatocytes, which leads to liver fibrosis and cirrhosis, and ultimately liver dysfunction. The statistics of 2020 shows that the number of patients with CLDs, including chronic hepatitis, fatty liver, and cirrhosis, may exceed 447 million in China. The liver is a crucial organ for the metabolism of various substances, including sex hormones and lipids. CLDs frequently result in abnormalities in the metabolism of sex hormones, glucose, and lipids, as well as mental and psychological illnesses, all of which are significant risk factors for erectile dysfunction (ED). It has been reported that the prevalence of ED in male patients with CLDs ranges from 24.6 to 85.0%. According to a survey of Caucasians, liver transplantation may improve the erectile function of CLDs patients with ED. This finding supports the link between CLDs and ED. In addition, ED is often a precursor to a variety of chronic diseases. Given this correlation and the significant prevalence of CLDs, it is important to evaluate the epidemiology, risk factors, etiology, and treatment outcomes of ED in male patients with CLDs, expecting to attract widespread attention.

Prevalence of Chronic Infection by Hepatitis C Virus in Asymptomatic Population With Risk Factors in Cartagena, Colombia

Introduction

Infection by the hepatitis C virus (HCV) is an important cause of chronic liver disease, considered a public health problem worldwide with high morbidity and mortality due to limited access to diagnostic tests in developing countries. Only a small percentage know their infection status and receive timely treatment. It is critical to make diagnostic tests for HCV infection accessible and to provide timely treatment, which not only reduces the spread of infection but also stops the progression of HCV disease without symptoms.

Objective

To determine the prevalence of chronic infection by HCV in patients with risk factors by using rapid tests in Cartagena, Colombia, and describe their epidemiological characteristics.

Methodology

A cross-sectional descriptive observational study was carried out on asymptomatic adults with risk factors for HCV infection in the city of Cartagena between December 2017 and November 2019. A rapid immunochromatographic test was performed to detect antibodies, characterizing the population.

Results

In total, 1,023 patients were identified who met the inclusion criteria, 58.5% women and 41.4% men, obtaining nine positive results, confirming chronic infection with viral load for HCV, finding seven cases of genotype 1b and two genotype 1a.

Conclusion

In our study, a prevalence of hepatitis C infection of 0.9% was found in asymptomatic individuals with risk factors, which allows us to deduce that the active search for cases in risk groups constitutes a pillar for the identification of the disease, the initiation of antiviral therapy, and decreased morbidity and mortality.

Male Sexual Dysfunction and Infertility in Spinal Cord Injury Patients: State-of-the-Art and Future Perspectives

Spinal cord injury (SCI) is a relevant medical and social problem. According to the World Health Organization, the commonly estimated worldwide annual incidence of SCI is 40 to 80 cases per million population. After the SCI experience, most men present with sexual dysfunction (erectile dysfunction (ED) and ejaculatory dysfunction), fertility problems (such as impaired spermatogenesis, abnormalities in sperm viability, motility, and morphology), and systemic disorders such as genitourinary infection and endocrine imbalances. The best options available for managing the ejaculatory disorders in patients suffering from SCI are penile vibratory stimulation (PVS) and electroejaculation (EEJ). Furthermore, the treatment of ED in SCI patients consists of medical therapies including phosphodiesterase 5 inhibitors (PDE5i), intracavernosal injections (ICI), vacuum erection devices (VEDs), and surgical as penile prosthesis (PP). This review provides a snapshot of the current evidence for the mechanisms of sexual dysfunction and infertility in SCI patients, discusses the best management strategies for these conditions, and offers our perspective on the direction of future research.

Long-term hepatic function of patients with compensated cirrhosis following successful direct-acting antiviral treatment for hepatitis C virus infection

BACKGROUND AND AIM

Direct-acting antivirals (DAAs) have contributed to the improvement of outcomes for all patients with chronic hepatitis C. The aim of this study was to evaluate the long-term hepatic benefits of hepatitis C virus (HCV) cure by DAAs in patients with compensated cirrhosis.

METHODS

This multicenter cohort study consisted of consecutive patients with compensated cirrhosis who initiated interferon-free DAA treatment before September 2016. The impact of treatment on long-term hepatic function was followed for at least 4 years after the end of treatment, and the progression to decompensation was evaluated.

RESULTS

The data of 394 patients were available for study. The median age was 70, and 41% had modified albumin-bilirubin (ALBI) grade 2b. During a short-term follow-up 1 year after the end of treatment, FIB-4 index and ALBI score significantly improved. The achievement rates of FIB-4 < 3.25 (40%) and ALBI grade 1 (70%) reached their plateau in the first year; however, there were significant further improvements in platelet count and α-fetoprotein level after the first year. The annual incidence of decompensation was 1.30 (95% confidence interval 0.83-2.02) per 100 person-years. In multivariable analysis, male sex and modified ALBI grade 2b at baseline were associated with decompensation.

CONCLUSIONS

In a large real-world cohort of patients with compensated cirrhosis treated with a DAA, remarkable improvement in hepatic function was seen after HCV cure, especially during the first year after the end of treatment. Treatment in the early stage of cirrhosis would be of great benefit for preventing liver deterioration to decompensation.

Prevalence and risk factors of erectile dysfunction in patients with liver cirrhosis: a systematic review and meta-analysis

BACKGROUND AND AIMS

Liver cirrhosis is associated with an increased risk of developing erectile dysfunction (ED). The aim of this systematic review and meta-analysis was to evaluate the prevalence of ED and its risk factors in male patients with liver cirrhosis.

METHODS

A systematic search of PubMed (Medline), EMBASE, OVID Medline, the Cochrane Library, and other databases was performed for this review. Two investigators reviewed the abstracts obtained from the search and selected manuscripts for full-text review. The event rates were calculated with random-effects model and quality effects model.

RESULTS

Fourteen studies evaluating ED with the International Index of Erectile Function (IIEF) scores were selected. A total of 770 patients with liver cirrhosis were analyzed. The prevalence of ED in cirrhotic patients was 79% [decompensated: 88.4%, CI 35.95-70.84%, I² heterogeneity 85%; compensated: 53.6%, CI 77.64-32%, I² heterogeneity 80%]. Through a meta-regression analysis, we discovered that the presence of decompensation, use of beta-blocker and diuretics were related with ED. In addition, risk factors for ED included high body mass index [odds ratio (OR) 1.13, 95% CI 1.01-1.26], advanced Child-Pugh class (OR 2.29, 95% CI 1.12-4.72), MELD score (OR 1.19, 95% CI 1.05-1.35), diabetes (OR 3.44, 95% CI 1.38-8.57), and hypertension (OR 8.24, 95% CI 1.62-41.99).

CONCLUSION

ED is relatively common in male patients with cirrhosis, and presence of risk factors increases the prevalence of ED.

The effect of direct acting antiviral agents on vascular endothelial function in Egyptian patients with chronic hepatitis C virus infection

Chronic hepatitis C virus (HCV) infection is correlated with cerebrovascular and cardiovascular disease (CVD). This study aimed to assess the effect of treatment with DAAs on vascular endothelial function in cirrhotic and non-cirrhotic HCV infected patients without any CVD risk factors. Fifty chronic HCV genotype 4 infected patients, without cardiovascular risks who have been listed to receive sofosbuvir/daclatasvir with ribavirin combination as triple therapy for 3 months were prospectively recruited. Endothelial dysfunction markers as soluble vascular cell adhesion molecule-1 (sVCAM-1) and Von willebrand factor (vWf) and inflammation marker (IL6) were estimated at baseline and 3 months post the end of therapy (SVR). All patients achieved SVR. VCAM1 level was significantly improved after HCV clearance with DAA in cirrhotic HCV patients (P = 0.002) compared to patients with mild liver fibrosis (P = 0.006). Levels of vWF also decreased significantly in cirrhosis and non-cirrhosis groups after SVR (P < 0.001 and P = 0.011, respectively). Systemic inflammatory marker (IL6) showed significant decrease in cirrhotic patients (P = 0.001). While, IL6 level did not change significantly in non-cirrhotic group (P = 0.061). Also at SVR, noninvasive liver fibrosis indices have been reduced significantly in the two groups (P < 0.001). HCV clearance by new DAA treatment improves the vascular endothelial dysfunction in Egyptian HCV infected patients with different levels of liver fibrosis and with no risk factors for endothelial dysfunction or CVD.

Sexual Dysfunction in Patients With Chronic Gastrointestinal and Liver Diseases: A neglected Issue

INTRODUCTION

Normal sexual activity is an important determinant of quality of life. Unfortunately, several chronic health disorders are associated with an impaired sexual function.

OBJECTIVE

To provide coverage of the current literature on prevalence and pathophysiology of sexual dysfunction in patients with gastrointestinal and liver disorders METHODS: A Comprehensive review of the literature on the prevalence of sexual dysfunction in chronic gastrointestinal and liver disorders, assessing the underlying mechanism (s) was performed.

RESULTS

Many gastrointestinal disorders, either functional or organic, are associated with some degree of sexual dysfunction. The main pathogenic mechanisms are: (i) the disease itself causing fatigue, anxiety or depression with a potential alteration of self-esteem; (ii) worry of transmitting a potential infectious agent through sexual activity; (iii) alteration of the endocrine mechanisms which are necessary for normal sexual functioning; (iv) chronic pro- inflammatory conditions which may cause endothelial dysfunction and abnormal vascular responses; (v) iatrogenic.

CONCLUSION

Based on this review, a thorough evaluation of sexual function through validated questionnaires and/or psychological interviews with patients with chronic gastrointestinal disorders should be part of the clinical assessment in order to timely diagnose and possibly treat sexual dysfunction in this clinical setting.

Efficacy and safety of low-intensity shockwave therapy plus tadalafil 5 mg once daily in men with type 2 diabetes mellitus and erectile dysfunction: a matched-pair comparison study

Low-intensity extracorporeal shockwave therapy (LiESWT) represents a promising treatment for patients with erectile dysfunction (ED). We investigated the efficacy of LiESWT combined with tadalafil 5 mg once daily in men with type 2 diabetes mellitus (T2DM) and ED and compared LiESWT protocols administering different number of shockwaves. We performed a retrospective matched-pair comparison using data from a prospectively maintained database. Seventy-eight patients who received tadalafil 5 mg once daily for 12 weeks + LiESWT performed with an electrohydraulic source for 3 weeks (Group A) were matched 1:1 to patients who received tadalafil 5 mg once daily alone for 12 weeks (Group B). A subgroup analysis was performed according to the number of shockwaves delivered during each session (1500, 1800, and 2400 in subgroup A1, A2, and A3, respectively). The mean International Index of Erectile Function-5 (IIEF-5) score variations with respect to baseline recorded at 4, 12, and 24 weeks after the end of the treatment were investigated as treatment outcomes. The mean IIEF-5 scores significantly improved in all groups and subgroups at 4-week follow-up without intergroup differences. At 12- and 24-week follow-up, the mean IIEF-5 improvement was significantly higher among patients in the A3 subgroup (+5.0 ± 2.1 [P < 0.001] and +4.7 ± 2.3 [P < 0.001], respectively). The combined approach with tadalafil 5 mg once daily and LiESWT with a protocol involving 2400 shockwaves provides significant advantages in terms of IIEF-5 improvement and durability compared to tadalafil 5 mg once daily alone in patients with T2DM and ED.

Improvement of sexual dysfunction in patients after treatment of hepatitis C virus using directly acting antivirals

OBJECTIVE

The impact on male and female sexual dysfunction of treating hepatitis C virus (HCV) using direct-acting antiviral agents (DAAs) has not been sufficiently studied. The aim of this study was to assess the impact of HCV clearance with DAAs on sexual dysfunction (SD) in both sexes.

METHODS

In chronic HCV patients who were eligible for DAAs, 100 sexually active men completed the Arabic version of the international index of erectile function questionnaire (IIEF-5), and the same number of sexually active women completed Female Sexual Function Index (FSFI), before, at the end of, and 3 months after, treatment for HCV.

RESULT

The mean of the IIEF-5 scores for male patients was 16.29 ±.07 before treatment, 16.88 ± 3.63 3 months after treatment (p < .01), and was significantly higher, at 19.06 ± 3.31 6 months after treatment cessation (p < .01). In female patients, the mean total FSFI score at baseline was 19.22 ± 2.40 and after 3 months of treatment was 21.61 ± 3.45 (p < .01), with a significant increase (25.09 ± 4.52) after 6 months (p < .01). No difference in the improvement of sexual function was reported either after 3 months or at the end of treatment between males and females (p > .05).

CONCLUSIONS

Significant improvement in SD associated with HCV infection in both sexes was recorded following viral clearance using DAAs treatment.

Relationship between the risk factors of cardiovascular disease by testing biochemical markers and young men with erectile dysfunction: a case-control study

Background

Erectile dysfunction (ED) shares common risk factors with cardiovascular disease (CVD), such as diabetes mellitus (DM) and dyslipidemia, but the relationship between the risk factors of CVD in biochemical markers and young men with ED age 20–40 years is not fully clarified.

Methods

A total of 289 ED outpatients (20–40 years old) were allocated under ED group, based on patients’ complaints and physical examinations. According to the frequency matching ratio of 1:4, 1,155 male individuals (20–40 years old) without ED were set as control group. All participants were tested for lipid profiles including total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), blood glucose (BG), homocysteine (HCY), liver function including alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and renal function including uric acid (UA) and creatinine (CR). The study was designed to compare the two groups using an established binary logistic regression analysis model. The ED group was then subdivided into a younger ED group (20–30 years old) and an older ED group (31–40 years old) for further comparisons.

Results

After comparison, no obvious differences were found in medians of age, TC, TG, HDL, HCY, UA, and ALT in the two groups. Median LDL, BG, and CR were significantly higher and AST was much lower in the ED group (P<0.01). In binary logistic regression analysis, odds ratios (OR) for LDL, BG, CR, and AST were 1.279, 1.237, 1.026, and 0.978, respectively. The sensitivity value and specificity value were 43.25% and 72.56%, respectively. The medians of LDL, TG, and TC were higher and HDL was much lower in the older ED group, as compared with the younger group (P<0.05). No significant differences were displayed in medians of other biochemical markers in the above comparisons.

Conclusions

Elevated LDL, BG, and CR were related factors of ED in young men. Lipid profile was significantly different between young men with ED aged 20–30 and 31–40 years.

Effect of new oral direct acting antiviral therapy on sexual function in male patients with hepatitis C virus

Hepatitis C virus (HCV) infection is a major health problem all over the world including Egypt. Chronic HCV infection is usually accompanied by decrease of libido and erectile dysfunction. This study aimed to evaluate the efficacy of new oral direct acting antiviral (DAA) therapy on sexual function of male patients with HCV. This study was conducted on 200 male participants divided into two groups, first group included 100 male patients with HCV and the second group included 100 healthy age matched males as a control. Patients received DAA for three months and virological free status was confirmed by polymerase chain reaction. All participants were subjected to full history taking, general examination and local genital examination, assessment of sexual function by a validated Arabic version of the international index of erectile function-5. Laboratory investigations included liver functions serum testosterone, free testosterone, sex hormone-binding globulin and bioavailable testosterone. Results of this study showed that patients with HCV suffer from sexual dysfunction than controls that significantly improved after DAA therapy, and this is accompanied by increasing of bioavailable testosterone. It could be concluded that beside its effectiveness in treatment of HCV infection, DAA therapy can improve sexual function in male patients with HCV.

Endocrine disorders associated with hepatitis C virus chronic infection

The term "HCV syndrome" encompasses several organ- and systemic pathophysiological states, which often recognize autoimmunity or neoplastic evolution in their pathophysiology, as well as chronic HCV infection as trigger. The clinical features of HCV patients are heterogenous, and may include endocrine or metabolic disorders, namely autoimmune thyroiditis, type 2 diabetes mellitus, and erectile/sexual dysfunctions. In this review, we summarize current knowledge on the endocrine/metabolic diseases associated with chronic HCV infection, focusing on the main concepts emerged in the recent literature in this field. The application of this knowledge in everyday clinical practice may be relevant, in order to reinforce a holistic vision of the patient with chronic HCV infection, stimulating in turn a multi-disciplinary approach, thus increasing the probability of early diagnosis, more effective treatments, and a better prognostic outcome.
