Erectile dysfunction in chronic renal failure patients undergoing hemodialysis in Egypt

In clinical practice, the attention given to sexual problems in patients with end-stage renal disease is low. In order to evaluate the erectile function in chronic renal failure patients undergoing hemodialysis (HD) as a renal replacement therapy in upper Egypt, we used the abridged version of the International Index of Erectile Function (IIEF-5). In all, 75 HD patients were subjected to clinical and laboratory investigations. The controls were 948 healthy males representing the general Egyptian population. The prevalence of erectile dysfunction (ED) among the HD patients was 82.5% compared to 30% among controls. The prevalence of ED in HD group was significantly higher than in controls. The prevalence of ED in HD patients <50 y was 80% and it was 88% in those > or =50 y, while the prevalence of ED among controls was 28 and 69.8%, respectively. The prevalence of severe degree of ED was significantly higher in both groups compared to controls, while moderate degree of ED showed a statistical significance compared to controls in age groups <50 y and mild degree of ED showed a statistical significance compared to controls in age groups > or =50 y. [corrected] Age (r=-0.3368, P<0.01), serum urea (r=-0.5974, P<0.001), and creatinine level (r=-0.5804, P<0.001) have a significant negative correlation with the presence of ED among HD patients, while serum hemoglobin (r=0.3396, P<0.001) and years of HD age (r=0.3147, P<0.01) have a significant positive correlation with the presence of ED among the HD patients. In view of the observed high prevalence of ED among the HD patients, we believe that a complete health evaluation of male HD patients should include a discussion about erectile function in the standard clinical care program of patients with renal disease.     

Erectile dysfunction among Thai patients with COVID-19 infection

BackgroundErectile dysfunction (ED) is suspected to be the symptom manifestation of COVID-19. However, scarce data was presented this day. Our study was conducted to determine the prevalence of ED and its associated factors among Thai patients with COVID-19.MethodsSexually active males with COVID-19, hospitalized between May and July 2021 at one university hospital in Bangkok, were screened for erectile dysfunction by the International Index of Erectile Function 5 (IIEF-5). Demographic data and COVID-19 treatment history were collected. Mental health status, including depression and anxiety, was evaluated with the Thai Patient Health Questionnaire 9 (PHQ-9) and the Generalized Anxiety Disorder Scale (GAD-7), respectively. The sample size was calculated, and logistic regression was used to analyze the association.ResultsOne hundred fifty-three men with COVID-19 were recruited. ED prevalence was 64.7%, of which severity was mostly mild. Logistic regression, adjusted for age, BMI, and medical comorbidities, portrayed a significant association between ED and mental health status. Higher risk of ED was found in participants with major depression [adjusted OR 8.45, 95% CI: 1.01–70.96, P=0.049] and higher GAD-7 total score [adjusted OR 1.15, 95% CI: 1.01–1.31, P=0.039].ConclusionsThai patients with COVID-19 had high prevalence of ED, which was associated with mental disorders. Thus, screening for mental problems is recommended in individuals with COVID-19 and ED.     

脆性X综合征男性患者的勃起功能障碍导致用非侵入性方法无法采集到精液(英文)

目的:报道脆性 X 综合征男性患者精子样本采集过程中的临床经验。方法:采用基于两种不同 PCR 的方法对患者进行脆性 X 综合征分子诊断。精子采集大部分根据世界卫生组织的实验室手册进行。结果:5位年龄在18—60岁的脆性 X 综合征男性患者均表现出意外的勃起功能障碍,导致我们无法从这些患者中采集到精子样本。这5个患者在不同的时间或者由不同医生进行检查都得到同样的结果。结论:勃起反射是健康男性的本能反应,勃起功能障碍可能与激素、组织器官发育或神经调控回路异常有关。由于文献报导脆性 X 综合征男性患者的激素水平正常,所以可能是后二者的异常或者其中之一的异常而引起该类病人的勃起功能障碍。这一发现可能有助于更好地理解脆性 X 综合征的临床范围和发病机制。     

Erectile dysfunction in heart disease patients

Atherosclerosis is a general health problem that not only affects the coronary arteries but also (in men) the penile arteries, thus contributing to organic causes of erectile dysfunction (ED) in heart disease patients. These organic causes are intertwined with psychological and pharmacological causes because medication prescribed for heart disease patients may also cause ED. The incidence of ED after myocardial infarction ranges from 38 to 78%. As sexual intercourse involves physical exertion, the medical history, ventricular function determined through echocardiography, and stress testing are used to classify patients into various groups where coital activity represents a greater or lesser cardiovascular risk. The energy requirements for intercourse are not high, ranging from 3.7 metabolic equivalents (METs) of energy expenditure at resting state during the preorgasmic phase to 5 METs during orgasm. The Bruce protocol for exercise stress testing is a six-stage protocol with changes in the slope and speed of the treadmill. As a general rule, a patient who completes the first two stages of the Bruce protocol has a functional capacity greater than 7 METs, which is considered sufficient for sexual intercourse. The physician or cardiologist concerned should institute first-line treatment with oral drugs according to the indications listed below. If sexual activity is not contraindicated, the treatment of choice for ED in heart disease patients is oral therapy with sildenafil, except in those cases in which its use is contraindicated. Specific recommendations are discussed.     

Erectile dysfunction

The past several years have witnessed a veritable revolution in our understanding and management of erectile dysfunction. Although surgical implants in the form of penile prostheses continue to be an important part of treatment of end-stage cases, the largest change has been brought about by the introduction of oral medications, such as sildenafil (Viagra). This review addresses the etiology, epidemiology, diagnosis, and treatment of erectile dysfunction in light of the remarkable advances in the field.     

Erectile dysfunction

PURPOSE: Male sexual health has taken on increased importance as the United States population ages, develops coexisting medical conditions and undergoes interventions that can affect sexual function. We characterized the burden and severity of disease, treatment patterns and economic consequences of erectile dysfunction. MATERIALS AND METHODS: The analytical methods used to generate these results were described previously. RESULTS: Erectile dysfunction was self-reported by almost 1 of 5 men and it increased with age. Erectile dysfunction may have been more commonly reported in Hispanic men and in those with a history of diabetes, obesity, smoking and hypertension. In most databases black American men had rates of use for office visits and inpatient hospital care that were twice those of other racial groups, although these rates were not controlled for comorbid conditions or other regional and socioeconomic factors. The use of diagnostic tests markedly decreased, while pharmacological therapy, especially with oral phosphodiesterase-5 inhibitors, markedly increased. Penile implant surgery continued to be performed with most patients electing inflatable devices. Extrapolating from the population based estimates of erectile dysfunction prevalence and current use trends showed that the cost of treatment nationwide could reach $15 billion if all men sought treatment. CONCLUSIONS: The burden of disease due to erectile dysfunction in the United States will increase with the aging of the male population, increasing prevalence of comorbid conditions, expanded treatment seeking behavior and costs of pharmaceutical therapy. Accurate estimates of economic cost will require better understanding of pathogenesis, treatment seeking behavior, patient preference for therapies, success of treatments and relative satisfaction with oral pharmacotherapy and penile implants.     

Erectile dysfunction

In Spain, based on the IIEF, 19% of males between 25 and 70 years old present some degree of erectile dysfunction (ED). Therefore, around 2,000,000 Spanish men present this condition and could require medical attention for it. Here, we present an up-date of the most important aspects of erectile dysfunction (pathophysiology, diagnosis and treatment). We review, in detail, the oral treatments and future drugs that are presently in the premarketing experimental phase. Diagnostic and therapeutic management of the patient with erectile dysfunction should be individualized, taking into account the goals of each patient. It is highly recommendable to carry out a basic assessment (comprehensive clinical history, physical examination, recommended lab testing). If previously undiagnosed diseases are discovered (diabetes, arteriosclerosis, etc.) these should be treated and modifiable risk factors should be corrected. There are numerous therapeutic options for the treatment of erectile dysfunction. Replacement therapy with testosterone should only be used in males with ED and low levels of this hormone, under medical supervision. At present, first line treatment consists of the administration of oral drugs (sildenafil, apomorphine). There are two new PDE 5 inhibitors (tadalafil and vardenafil) that will be released on the market 2003, which will provide better selectivity. Moreover, several drugs for oral administration are in the initial phases of research that will facilitate erection via a direct penile action. When oral drugs are contraindicated, are not effective or when they are unpopular with the patient, the second line of treatment is intracavernous injection. Prostaglandin E1 is the initial drug of choice in patients using intracavernous autoinjection for the first time and has a high efficacy. Implantation of a penis prosthesis and penile revascularisation are appropriate for highly selected patients. Psychotherapy can be an option for men with ED of psychogenic origin, either as a monotherapy or combined with sildenafil or apomorphine.     

Erectile dysfunction in patients with first-episode psychosis

Sexual dysfunction is more prevalent in psychotic patients than in the nonpsychotic population. The objective of this study was to identify correlations between serum prolactin levels, testosterone levels and erectile dysfunction in patients with first-episode psychosis (n = 40) compared to age-matched healthy controls (n = 40). All subjects underwent clinical evaluation, international index of erectile function (IIEF5) score assessment and measurement of serum prolactin and total testosterone levels. In first-episode psychotic patients, the IIEF-5 score and total testosterone levels were significantly lower, while serum prolactin levels were higher. We concluded that men with first-episode psychosis are at an increased risk for development of erectile dysfunction, and increased duration of untreated psychosis leads to a higher incidence of erectile dysfunction and hyperprolactinemia.     

Erectile dysfunction in patients with coronary artery disease

Recent studies suggest that erectile dysfunction (ED) may be an early marker of endothelial dysfunction and coronary artery disease (CAD). Conversely, patients with CAD commonly have ED. The phosphodiesterase 5 (PDE5) inhibitors are very effective for the treatment of ED in patients with CAD. Numerous studies show that this class of drugs is in general safe in patients with stable CAD and these agents do not exacerbate ischemia in men with CAD undergoing exercise stress testing. Analysis of placebo-controlled trials did not show an increase in cardiovascular events among men receiving PDE5 inhibitors, and post-marketing surveillance studies with sildenafil did not observe an increase in cardiovascular events compared to expected age-matched rates. Organic nitrates remain a contraindication for PDE5 inhibitors and alpha blockers have precautions/contraindications depending upon specific drugs. The Princeton Consensus Guidelines (soon to be updated) suggest a logical approach to the patient with CAD seeking therapy for sexual dysfunction.     

Erectile dysfunction in hemodialysis patients with diabetes mellitus: Association with age and hemoglobin A1c levels

Abstract Aim: Erectile dysfunction (ED) is common in patients with diabetes mellitus (DM) as well as those undergoing hemodialysis (HD). The purpose of this study is to investigate the frequency and severity of ED in HD patients with DM and those without DM. In addition, we examined the relationship between erectile function and several risk factors, including presence of DM and hemoglobin A1c levels in HD patients. Methods: This study involved 180 patients on HD, including 66 HD patients with DM (DM‐HD) and 114 patients without DM (non‐DM‐HD). We evaluated erectile function using an abridged five‐item version of the international index of erectile function (IIEF‐5). Logistic regression analysis was used to investigate the relationship between presence of ED and several risk factors. Results: The total score of IIEF‐5 in DM‐HD patients (9.5 ± 4.2) was significantly lower than in non‐DM‐HD patients (13.5 ± 5.7). The prevalence of severe ED was 42.4% and 18.4% in DM‐HD patients and non‐DM‐HD patients, respectively. Age, cardiovascular disease history, and DM were identified as independent risk factors for the presence of ED. Furthermore, age and elevated hemoglobin A1c levels were identified as independent risk factors for the presence of severe ED. Conclusion: DM‐HD patients are more likely to have ED, and particularly severe forms of ED, than non‐DM‐HD patients. DM and elevated hemoglobin A1c levels were associated with the presence of ED or severe ED, respectively. Aging was identified as an independent factor in both ED and severe ED.     

Erectile dysfunction and hypertension

Recent analyses suggest that about 67-68% of men with hypertension have some degree of erectile dysfunction (ED). With about 25 million men in the US with hypertension, substantial numbers of hypertension-related ED exist that tend to be of a more severe nature than the general population. Men with ED are also more likely to have hypertension. Thiazide diuretic and beta-blocker therapy may contribute to ED. Phosphodiesterase-5 (PDE5) inhibitors are effective therapy in men with ED owing to hypertension who are taking antihypertensive medicines including those on multiple antihypertensive medicines. The addition of PDE5 inhibitors to usual common antihypertensive medicines (diuretics, beta blockers, calcium blockers, angiotensin converting enzyme inhibitors and angiotensin receptor blockers) results in either no or small additive reductions in blood pressure (BP) and no increase in serious clinical adverse events. There are however precautions regarding the use of PDE5 inhibitors in patients taking alpha blockers for either hypertension or benign prostatic hypertrophy, as some patients may develop orthostatic hypotension. Organic nitrates remain an absolute contraindication for PDE5 inhibitors because synergistic and symptomatic reductions in BP may occur in some patients with this drug combination.     

Erectile dysfunction in testicular cancer patients treated with chemotherapy

Information on male potency in testicular cancer (TC) patients treated with chemotherapy is insufficient. We aimed to assess the levels of depression and anxiety symptoms, sexual function and gonodotrophins. Participants (n = 27) were identified and recruited from the genitourinary services of two medical centres, one in Inonu University and the other in the Firat University. All patients are TC patients treated with chemotherapy after unilateral orchiectomy. Participants completed follow-up assessments after the completion of the chemotherapy regimen. Serum luteinising hormone, follicle-stimulating hormone and testosterone levels were determined after blood samples had been taken in the morning after an overnight fast. International Index of Erectile Function (IIEF-15) was also used to evaluate erectile dysfunction (ED) score. Beck Depression and Beck Anxiety Scale were used to assess psychological symptoms. The findings indicated that men treated with chemotherapy had significantly different IIEF-15 and Beck Anxiety scores compared with men who did not receive chemotherapy. But no statistically significant difference was determined in the serum gonodotrophin levels and depression score between the two groups. It is concluded that patients with TC undergoing chemotherapy have greater risk than normal men for ED, independently of the gonodotrophin's level.
