Detailed Description

Erectile dysfunction (ED) is an inability to provide adequate erection to initiate or maintain any sexual activity. The ED prevalence in adult males is approximately 20%. Cardiovascular diseases, diabetes mellitus(DM), chronic systemic diseases, smoking and obesity are among the aetiology of ED .In recent years, publications indicating that active inflammatory processes cause ED are increasing. In these studies where neutrophil- lymphocyte (NLR) and platelet-lymphocyte ratios (PLR) were used as signs of inflammation, a significant relationship was found between diseases with these proportions .Neutrophil-to-lymphocyte ratio (NLR) is a simple parameter to assess easily the inflammatory status of a subject. It has proven its usefulness in the stratification of mortality in major cardiac events , as a strong prognostic factor in several types of cancers , or as a predictor and a marker of inflammatory or infectious pathologies (such is pediatric appendicitis) and postoperative complications. Through enhanced production of cytokines and expression of cellular adhesion molecules, the dysfunctional endothelium promotes inflammation within the vascular wall and sets the stage for initiation and progression of atherosclerotic lesions in both penile vasculature and in peripheral and coronary blood vessels. It has been shown that patients with vasculogenic ED have increased inflammatory activation compared to subjects without ED.There are numerous studies suggesting that phosphodiesterase-5(PDE-5) inhibitors, which are the first-line therapy of ED, might be effective in reversing generalized endothelial dysfunction. Chronic treatment restores endothelium-dependent relaxations at various sites of the vascular tree, even up to one week after cessation of the treatment . Previous studies reported a chronic effect of sildenafil and tadalafil on endothelial function and pro-inflammatory markers/mediators including intercellular and vascular cell adhesion molecules-1 (ICAM-1 and VCAM-1, respectively), high sensitivity C-reactive protein (hsCRP), and interleukin-6

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
