Conditions
Summary
The goal of this clinical trial is to examine the genetic markers of erectile dysfunction degree in patients with diabetes and find new predictive models based on genetic factors, with which we will be able to more accurately address the adequacy of treatment in patients with diabetes, and thus have a long-term impact to reduce side effects of treatment. We will look for a predictive model based on genetic analysis to determine in the future patients with a good response to treatment with phosphodiesterase type 5 inhibitors, in our case tadalafil 5 mg daily. The main questions it aims to answer are: 1. Genetic alterations in the NO signaling pathway affect the degree of erectile dysfunction and the response to tadalafil treatment in patients with diabetes. 2. Genetic alterations in the folate pathway affect the degree of erectile dysfunction and the response to tadalafil treatment in patients with diabetes. 3. Genetic factors of the vascular wall influence the degree of erectile dysfunction and the response to tadalafil treatment in patients with diabetes. 4. Genetic changes in the pathways of tadalafil metabolism and action influence the response to the treatment of erectile dysfunction in patients with diabetes. Participants will take the drug tadalafil 5 mg every day for three months. The level of erectile dysfunction will be assessed with the IIEF-5 questionnaire at the beginning of the study and after three months of taking the drug.
Eligibility
Inclusion Criteria1
- We will include in the study 90 patients with diabetes and erectile dysfunction. We will use the IIEF-5 questionnaire to confirm the diagnosis of erectile dysfunction. Patients between the ages of 40 and 65 who score 21 points or less on the IIEF-5 scale will be included in the study.
Exclusion Criteria1
- patients receiving any form of organic nitrate in regular therapy or as necessary due to ischemic heart disease, patients who have already suffered a cardiovascular event (heart attack, stroke, manifest peripheral arterial disease), users of illegal drugs, alcoholics, demented patients , patients with psychiatric diseases, patients with pancreatogenic form of diabetes, patients with glucocorticoids and immunosuppressants induced form of diabetes and patients with monogenic form of diabetes. Patients with hypogonadism, prostate malignancy, patients with a psychogenic form of erectile dysfunction, patients with premalignant and malignant genital lesions, patients with Peyronie's disease, patients after injury, surgery and radiation in the pelvic area and patients with congenital diseases of the penis will also be excluded from the research. We will also exclude from the research patients who withdraw from participation in the research during the research for personal or any other reasons.
