Status Active, not recruiting

Clinical Trial Summary

Erectile dysfunction patients who are non responder to sildenafil will be treated with hyperbaric oxygen therapy with 100% concentration and at 2 ATM for 30 consecutive sessions each one 90 minutes and then will be reassessed.

Clinical Trial Description

This study is double blinded randomized controlled clinical trial that includes organic ED patients who attend to the Andrology out patient clinics, Department of Dermatology, Venerology and Andrology, Sohag University hospital, Sohag, Egypt. Informed consent was obtained from all patients. The study was submitted for approval by Ethical and Research committees at Sohag Faculty of Medicine, Sohag University, Sohag, Egypt. Study design: Patients were divided into two groups (randomly assigned and comparably cross matched for age). Both patients and the investigators were blinded as regard the treatment until the end of the study. Group 1: Patients assigned to the HBOT group were treated with (30) sessions in consecutive days (90 minutes of 100% oxygen at 2.2 ATM). Group 1: Patients assigned to control group were exposed to (30) sessions of air oxygen tension at 2.2 ATM. All patients were subjected to the following: 1. Medical history: - Personal history: Age, residence, marital status, occupation and special habits of medical importance. - ED history: Onset, course and duration. - Sexual History: duration of marriage, wife age, frequency of intercourse, morning erection, orgasm, libido, percent of weakness, type and dose of PDE5I and its response after proper instructions and ejaculation. - Medical history : History of medical diseases (Hypertension, Diabetes mellitus, Liver disease and any chronic disease). - Therapeutic history: previous ED treatment modalities and response to them in addition to other current drug intake. - Past history of operations. 2. General examination: It included height, weight, BMI, Blood Pressure, hair distribution, fat distribution and breast examination. Blood pressure and pulse. 3. Local examination: Penis: (stretched flaccid length, urethral meatus, deformities and fibrosis). Testes: (site, size, consistency). Spermatic cord. Any scar of previous operations. 4. Erectile function evaluation: 4-1- Arabic version of the sexual health inventory for men (SHIM): The SHIM is a five-item scale in which each item is scored from 0 to 5 on four items and 1 to 5 on one item. It includes four of the six items from the original erectile function domain of the IIEF and includes items in maintenance ability, erection confidence, maintenance frequency and erection firmness in addition to a single item on intercourse satisfaction. Among men in a relationship with a partner, including those men who have opportunity but no desire to attempt sexual activity or intercourse. Disease grades of ED on SHIM scores were categorized as follows: severe ED (SHIM score:1-7), moderate ED (8-11), mild-to-moderate ED(12-16), mild (17-21), and no ED (22-25). A cut off value of 21 was chosen, so that patients with scores of 21 or less were classified as having had ED while patients with scores above 21were classified as having no ED. 4-2- Arabic version of Erection Hardness Score (EHS): The EHS is a single-item instrument that asks men to rate erection hardness on a scale that ranges from 0 (penis does not enlarge) to 4 (penis is completely hard and fully rigid). 4-3- The sexual health encounter profile (SEP- Questions 2 and 3): The treatment efficacy evaluated through asking the patients to answer the SEP-Q2 and SEP-Q3 with yes or no. SEP-Q2: Were you able to insert your penis into your partner's vagina? SEP-Q3: Did your erection last long enough for you to have successful intercourse? 4-4- Penile color Doppler: Patients evaluated by penile color Doppler after intra-cavernosal injection of 1 ml of Prostaglandin E1 (10 µg/ml). Key parameters included PSV, (cavernosal artery blood flow rate at start of systole) and EDV, (cavernosal artery blood flow rate at the end of diastole. PSV <30 cm/s is considered evidence of arterial insufficiency (arteriogenic ED) and EDV >5 cm/s is consistent with venoocclusive ED. RI (defined as PSV-EDV/PSV) is an indicator for venoocclusive function assessment. RI >0.80 have been cited as indicative of normal veno-occlusive function. 5. Laboratory investigations: Patients evaluated with random blood sugar, lipid profile after 12 hours fasting, and serum uric acid. A morning 8:00- 10:00 a.m. blood sample collected for measurement of total and free testosterone. 6. Safety evaluation: Safety and tolerability evaluated throughout the course of the study by assessing adverse events reported by either the patient or the physician. 7. Follow up evaluation: Patients evaluated at 3 points as follow: The first initial evaluation, The second evaluation at the end of sessions and The third evaluation 3months after stoppage of sessions. The evaluation tools were as follow: Erectile function evaluation: SHIM- EHS- SEP- Penile color Doppler, Laboratory evaluation: Total and free testosterone and Safety evaluation. Outcome measures: The outcome measures were: SHIM- EHS- SEP- penile Doppler parameters - response to PDE5i- reported side effects by physician and /or patients. Statistical analysis: Data analyzed using Statistical Package for Social Sciences SPSS) software program (version 16). All variables checked for normality. Quantitative variables with normal distribution presented as means ± standard deviation (SD). While quantitative variables with no normal distribution presented as median (25th-75th percentile). Qualitative variables recorded as frequencies and percentages . Comparison between continuous variables with normal distribution done by student t- test, while continuous variables with no normal distribution done by Mann-Whitney test. Qualitative variables compared by chi-square test. Correlations between different variable performed when indicated with appropriate tests. Regression analysis done if indicated. P value < 0.05 considered significant. ;
