Abstract Introduction Erectile dysfunction (ED) is a known precursor and sequelae to diagnosed cardiovascular disease (CVD). ED severity predicts CVD severity. AUA guidelines recommend evaluating serum lipids and using an ED diagnosis as an opportunity to discuss and address cardiovascular risk. Serum plasma ceramides are novel predictors of adverse cardiovascular events independent of traditional risk factors such as LDL and hsCRP levels. Ceramide levels improve with lifestyle modification. Objective We aimed to evaluate the utility of ceramide levels in ED patients utilizing self-reported erectile function results (IIEF-6). Methods We initiated ceramide testing in all patients with ED and Peyronie’s disease in late 2019 (in addition to lipids, Hgba1c, etc). We retrospectively analyzed ceramide levels from electronic records with IIEF-6 results. For the statistical analysis we dichotomized our cohort by ED symptom severity (moderate/severe ED: IIEF ≤17 vs. no/mild ED: IIEF ≥18) and ceramide levels by CV risk strata (moderate or higher >6). A Fisher exact test was performed. Results A total of 354 patients were reviewed, of these 253 (71.4%) had moderate ED or higher. A statistically significant difference in abnormal ceramide values was found in patients with mild to moderate symptoms severity or higher, and the odds of getting an abnormal ceramide test was increased based on the IIEF scoring alone (OR 2.3 [1.04– 5.12]; p value = 0.034) [Figure]. Conclusions Patients undergoing management for erectile dysfunction may benefit from serum ceramide testing and subsequent cardiac referral. In our cohort, men with moderate to severe ED were twice as likely to have actionable ceramide levels. Further study is warranted to optimize utility of ceramide in men with ED and potentially drive lifestyle change. Disclosure No.

ABSTRACT Introduction The significant overlap of risk factors for erectile dysfunction and venous thromboembolism (VTE) may disproportionally increase the risk of VTE in men undergoing inflatable penile prosthesis (IPP) surgery. Owing to the absence of available literature, AUA and EAU perioperative VTE guidelines do not address VTE risk with IPP surgery and generally recommend against pharmacologic prophylaxis with outpatient surgery. The Caprini Score is a validated scoring system to estimate VTE risk in the perioperative period. Objective We sought to assess the risk of VTE by calculating Caprini Scores in men undergoing IPP surgery. Methods We retrospectively reviewed and calculated Caprini Scores for patients undergoing IPP surgery at our institution between July 2017 and June 2019. Results 215 patients undergoing IPP surgery were identified with a mean and median Caprini score of 5.96 (SD, 1.63) and 6 (IQR 5,7), respectively. 84% of the cohort was classified as high or highest risk for VTE (Figure 1). This is in part due to our cohort's mean age of 64, mean BMI of 31 and history of prostate cancer treatment as the cause of ED. Prior history of VTE (deep vein thrombosis(DVT) or pulmonary embolism (PE)was identified in 17 (8%) patients with 5 (2%) have a history of both DVT and PE. Conclusions Men undergoing IPP surgery are high risk for VTE based on Caprini score assessment. VTE prophylaxis should be considered in men undergoing penile implant surgery. Before widespread application, long-term data is necessary to assess safety and efficacy of VTE prophylaxis in the IPP surgery population.

ABSTRACT Introduction Erectile dysfunction (ED) is a known precursor and sequelae to diagnosed cardiovascular disease (CVD). ED AUA guidelines recommend evaluating standard CV risk factors including serum lipids and penile doppler to help stratify CV risk, but few patients are referred for further evaluation. Plasma ceramides are metabolic byproducts that are novel predictors of adverse cardiovascular events resulting from unstable atherosclerotic plaque. CVD risk conferred by ceramide levels has been shown to be independent of conventional risk factors such as LDL and hsCRP levels. Thus, Plasma MI-Heart Ceramide is a new test that useful for evaluating shorter term major adverse cardiovascular events (MACE) in the next 1 to 5 years. Objective We sought to evaluate the utility of ceramide levels in ED patients Methods We initiated ceramide testing in all patients with ED in late 2019 (in addition to lipids and Hgba1c). We queried our electronic medical record for ceramide levels and men with a diagnosis of ED. Ceramide levels stratified patients in normal, moderate, high, and very high risk. Twenty eight patients additionally had penile duplex ultrasound (DUS). Left and right peak systolic velocity values were averaged and a value of <25 cm/s was defined as penile arterial insufficiency. Results 245 men with ED and ceramide levels were analyzed. 44% (n=107) were normal, 42% (n=103) were moderate risk, 12% (n=29) were high risk and 2% (n=6) were very high risk. As result of their ceramide and office evaluation, 42% (15/35) of high/very high risk patients were referred for cardiac evaluation. Comparing ceramide scores in men with penile arterial insufficiency (16.7 cm/sec) vs patients without (43.2 cm/sec), we found no significant difference (p=1). Similarly, when comparing DUS results between ceramide risk categories, we found no significant differences (p=1). Conclusions One in 7 men presenting to an ED clinic had a high or very high ceramide risk. DUS results did not correlate with ceramide risk. Patients undergoing DUS (even without arterial insufficiency) may benefit from additional ceramide testing and possible cardiac referral. Further study is warranted to optimize utility of ceramide in men with ED and potentially decrease peri-procedural IPP cardiac morbidity. Disclosure No
