Erectile dysfunction in the elderly: epidemiology, etiology and approaches to treatment.

PURPOSE: Erectile dysfunction is experienced at least some of the time by most men who have reached 45 years of age, and it is projected to affect 322 million men worldwide by 2025. The prevalence of erectile dysfunction is high in men of all ages and increases greatly in the elderly. MATERIALS AND METHODS: This paper reviews the epidemiology of erectile dysfunction with an emphasis on the experience of older men, normal age related changes in the structure and function of the penis that may contribute to increased risk with age, how the accumulation of risk factors with age may contribute to the high prevalence of the disease in older men, and established and emerging therapies. The normal aging process and age related risk factor accumulation contribute to the increased prevalence of erectile dysfunction in the elderly. RESULTS: Remarkable progress has been made in the treatment of erectile dysfunction. At present inhibition of phosphodiesterase 5 with oral agents such as sildenafil would appear to be the initial treatment of choice. These drugs have been shown to be safe and effective, and sildenafil has demonstrated efficacy in patients with many of the comorbidities observed in older men with erectile dysfunction. New treatments, in particular transfection with genes for key mediators of erectile function that are known to be down-regulated in elderly men, also hold promise. CONCLUSIONS: Further research into the neural, vascular and molecular mechanisms involved in penile erection will lead to the development of even safer, more effective and more convenient therapies for men with erectile dysfunction.

Erectile dysfunction and symptoms of sleep disorders.

STUDY OBJECTIVES: Sleep apnea often is associated with impotence and/or erectile dysfunction (ED). The purpose of this study was to test whether a presentation for ED confers a pretest probability for obstructive sleep apnea hypopnea syndrome (OSAHS). DESIGN: A self-report survey for sleep complaints was conducted in consecutive male patients (>16 years of age) presenting to a urologic practice site. SETTING: The survey was provided to new and follow-up out-patients over a 2 month period of time. Other information collected included the presenting complaint, the clinical diagnosis for ED, and history of preexisting medical conditions. PARTICIPANTS: N/A. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: 285 males [91% of the sample: 50 years old (range 16-82) and body mass index, 27.3 (range 16.8-52.5)] completed the survey. 181 (63%) had complaints of ED; of those, 76% had a final diagnosis of organic and 8.2%, psychogenic or both psychogenic and organic ED. Of all respondents, 35.4% reported persistent snoring, 14% reported persistent waketime sleepiness or fatigue, and 26.8% were at "high risk" (Netzer et al., 1999) for OSAHS. Some were high risk for insomnia (13.6%) and restless legs syndrome or for narcolepsy (2% each). There was a correlation between those with ED complaints (p<0.014) or those with a final diagnosis of organic ED (p<0.029) and snoring. In a logistic model that included age, snoring, and preexisting conditions, only age, depression, and history of hypercholesterolemia, were found to vary significantly among those with and without ED. CONCLUSIONS: Urology patients will report a variety of sleep problems, but neither persistent snoring nor suspected OSAHS is correlated uniquely to ED.

The accuracy of the increased prostate specific antigen level (greater than or equal to 20 ng./ml.) in predicting prostate cancer: is biopsy always required?

PURPOSE: Urologists are often referred patients who initially present with an extremely high serum prostate specific antigen (PSA) level. Despite a presumptive diagnosis of prostate cancer, many of these men undergo biopsy to obtain a tissue diagnosis before treatment with androgen ablative therapy. We examined a data base of men undergoing prostate biopsy to determine the accuracy of high PSA levels (greater than or equal to 20 ng./ml.) in predicting prostate cancer. MATERIALS AND METHODS: We reviewed the records of 1,250 consecutive patients undergoing transrectal ultrasound guided prostate biopsy at 1 institution. From this data base we identified all patients with PSA greater than or equal to 20 ng./ml. at the time of prostate biopsy. The accuracy of PSA in predicting cancer was determined by calculating positive predictive values for PSA ranges and PSA cutoffs. RESULTS: We identified 187 men (15%) presenting with PSA greater than or equal to 20 ng./ml. Of these 187 men 157 (84.0%) were diagnosed with prostate cancer on initial biopsy. Due to a negative initial biopsy, yet a high suspicion of cancer, 12 (6.4%) patients underwent at least 1 repeat biopsy. Of these 12 men 6 (50%) were diagnosed with cancer on repeat biopsy. Overall, 163 of the 187 men (87.2%) were diagnosed with prostate cancer by biopsy. Stratified by PSA ranges, positive predictive values were 73.6% for 20 to 29.9, 90.3% for 30 to 39.9, 93.8% for 40 to 49.9, 100% for 50 to 99.9, 95% for 100 to 199.9 and 100% for greater than or equal to 200 ng./ml. Using PSA cutoffs positive predictive values were 95.7% for PSA greater than or equal to 30, 97.6% for PSA greater than or equal to 40 and 98.5% for PSA greater than or equal to 50 ng./ml. CONCLUSIONS: Serum PSA, when increased above 50 ng./ml., is 98.5% accurate in predicting the presence of prostate cancer on tissue biopsy. Nonetheless, since transrectal prostate biopsy has a low complication rate and is relatively well tolerated, we recommend continuing to biopsy most patients with high PSA levels. However, carefully selected elderly patients on chronic anticoagulation, with severe co-morbidities or presenting with spinal cord compression may not require biopsy before androgen ablative therapy since PSA is highly accurate in diagnosing prostate cancer at levels greater than 50 ng./ml.

Efficacy and safety of sildenafil citrate (Viagra) in men with erectile dysfunction and spinal cord injury: a review.

Spinal cord injury (SCI) affects a substantial number of men who are young, active, and otherwise healthy. Erectile dysfunction (ED) is a common consequence of SCI. Since its approval, sildenafil citrate (Viagra) has been shown to effectively treat ED of various etiologies. We review the evidence for the efficacy and safety of sildenafil treatment of ED in men with SCI. A literature search identified 2 randomized controlled trials and 4 prospective case series that evaluated sildenafil treatment for ED from SCI. Efficacy was evaluated using an assessment of global efficacy and a more specific assessment of erectile function. For general efficacy, the proportion of patients who reported improved erections and ability to have intercourse was as high as 94%. Up to 72% of intercourse attempts were successful. For measures of erectile function, 5 of the 6 studies showed statistically significant improvements among sildenafil-treated versus placebo-treated patients. Erectile response rates were generally higher in patients with incomplete versus complete SCI and in patients with upper versus lower motor neuron lesions. Nevertheless, a substantial proportion of patients with complete lesions, regardless of level or lower motor neuron lesions, also benefited from sildenafil. Sildenafil was well tolerated. Incidence rates and types of adverse events that occurred in these studies were similar to those published previously. Symptoms of autonomic dysreflexia were not reported in any study. Existing evidence suggests that oral sildenafil is a highly effective and well-tolerated treatment for ED associated with SCI.

Distribution of chronic prostatitis in radical prostatectomy specimens with up-regulation of bcl-2 in areas of inflammation.

PURPOSE: We examined the anatomical relationship of chronic prostatitis with prostate cancer and benign prostatic hyperplasia (BPH) based on the hypothesis that there may be an association of prostatitis with these other entities that may involve up-regulation of bcl-2. MATERIALS AND METHODS: We examined 40 whole mount radical prostatectomy specimens for the presence and distribution of chronic inflammatory infiltrate. Immunostaining for bcl-2 was done in 10 cases. RESULTS: Chronic prostatitis was identified in all 40 cases with peripheral zone inflammation in 95% and transition zone inflammation in 87.5%. In all cases of transition zone inflammation the infiltrate was noted within and/or around BPH. Inflammatory infiltrate was microscopically associated with prostate cancer in 23 of the 40 cases (57.5%). In these 23 cases, there was no association of inflammation with Gleason score, preoperative prostate specific antigen, positive margins, or seminal vesicle invasion. Patients with BPH unassociated with prostatitis had significantly smaller prostate weight (median 32 gm.) and were younger (mean age 54.4 years) than those with BPH associated with prostatitis (median weight 40 gm. and mean age 61.4 years, p <0.05). Bcl-2 staining was intensified in benign glands within areas of prostatitis in all 10 cases examined. CONCLUSIONS: Chronic prostatitis is a common finding in radical prostatectomy specimens. Inflammation was associated with BPH and cancer but had a greater tendency to be associated with BPH. Bcl-2 was prominently expressed in areas of prostatitis. Our findings indirectly support a potential role for prostatitis in the pathogenesis of BPH.

Erectile dysfunction. Diagnosis and treatment in older men.

Erectile dysfunction (ED) affects nearly two-thirds of men age 50 and older and is an increasingly common presentation in the primary care setting. A thorough evaluation for ED involves a complete medical history, including a review of medical risk factors such as hypertension, diabetes, cardiovascular disease, renal failure, and medications, as well as lifestyle risk factors such as obesity and tobacco, alcohol, and illicit drug use; a detailed sexual history, including assessment of duration of ED, loss of libido, and overall sexual satisfaction; a physical examination; a psychosocial assessment--with particular attention to depressive symptoms; and appropriate laboratory tests. Treatments include medical management of multi-drug regimens, oral therapy, intracavernosal injection, testosterone replacement therapy, vacuum erection devices, and penile prostheses.

Restorative increases in serum testosterone levels are significantly correlated to improvements in sexual functioning.

It is recognized that testosterone (T) levels decrease in men with age, as does sexual function. We hypothesize that T supplementation in hypogonadal men with sexual dysfunction will restore certain elements of sexual function. Hypogonadal male subjects (total T < or = 300 ng/dL, n = 406, mean age 58 years) reporting one or more symptoms of low testosterone were randomized to T gel (50 mg/d and 100 mg/d), T patch, or placebo. Twenty-four-hour pharmacokinetic profiles for T were obtained. The 3 primary end points evaluated at 30 and 90 days posttreatment included a significant change in the frequency of intercourse and nighttime erections per 7-day week as well as a change in sexual desire measured on a Likert-type scale and calculated as a mean daily score. At day 30, a significant increase from baseline in sexual desire was noted for those on 100 mg/d T gel compared with those on 50 mg/d T gel, T patch, or placebo (1.2 vs 0.4, 0.7, and 0.4, respectively). A significant increase from baseline in the frequency of nighttime erections was also noted for those on 100 mg/d T gel compared with those on 50 mg/d T gel or placebo (51% of subjects in the 100 mg/d T gel group had an increase in frequency vs 30% for the 50 mg/d T gel group and 26% in the placebo group). Finally, a significant increase from baseline in the frequency of intercourse was evidenced for those on 100 mg/d T gel compared with those on T patch or placebo (39% of subjects in the 100 mg/d T gel group had an increase in frequency vs 21% for the T patch group and 24% in the placebo group). Similar results were seen for 100 mg/d T gel at day 90 for sexual desire and nighttime erections vs placebo. These data demonstrate a clear relationship between restoring serum T concentrations and improvement in certain parameters of sexual function. We propose that threshold T levels are needed in order to significantly affect improvements in sexual functioning.

Prostate-specific antigen changes in hypogonadal men treated with testosterone replacement.

Testosterone supplementation is commonly used as a treatment for hypogonadal men with or without erectile dysfunction. The effect of parenteral testosterone replacement therapy on the development or growth of prostate cancer is unclear. We assessed the effect of this treatment on serum prostate-specific antigen (PSA) levels and risk of prostate cancer in hypogonadal men with erectile dysfunction. Criteria for inclusion were a normal pre-treatment PSA (<4.0 ng/mL) in conjunction with a normal digital rectal examination (DRE) or a negative pretreatment prostate biopsy for men with either an abnormal DRE or an elevated PSA. Patients received intramuscular injections every 2 to 4 weeks, allowing for dose titration. In this retrospective analysis, 54 hypogonadal men with erectile dysfunction were included, with a mean age of 60.4 years (range 42.0-76.0) and a mean follow-up of 30.2 months (range 2.0-82.0) on testosterone therapy. Mean pretreatment total testosterone level was 1.89 ng/mL (range 0.2-2.92), which increased during treatment to a mean of 9.74 ng/mL (range 1.50-26.30, P <.001). Mean pretreatment PSA was 1.86 ng/mL (median 1.01 ng/mL, range 0.0-15.80), which increased to a mean PSA level of 2.82 ng/mL (median 1.56 ng/mL, range 0.0-32.36, P <.01) with testosterone treatment. Of the 54 men included in this study, 6 (11.1%) required prostate biopsy while on testosterone therapy because of a rise in serum PSA above 4.0 ng/mL. One patient (1.9%) was diagnosed with prostate cancer. In conclusion, testosterone replacement therapy in men with erectile dysfunction and hypogonadism is associated with a minor PSA elevation, but there does not appear to be a short-term increase in risk for the development of prostate cancer.
