RESUMO
INTRODUCTION: Benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are among the most common urological diseases in men. It has been repeatedly suggested that viral infection plays an important role in prostate carcinogenesis. AIM: To assess the relationship between viral infection and PCa, as well as the clinical and morphological features of BPH and PCa. MATERIALS AND METHODS: A total of 98 patients undergoing treatment for BPH (n=48) or PCa (n=50) between 2019 and 2021 were included in the study. Real-time PCR on the surgical specimens for human papillomaviruses (HPV), herpes simplex viruses types 1 and 2 (HSV-1 and HSV-2), cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes virus type 6 (HSV-6) was performed. RESULTS: In patients with PCa, viruses in prostate tissue were found more often compared to those with BPH (50.0 vs. 31.3%, respectively, p=0.046.) The most common virus in both PCa and BPH was EBV (22.0 vs. 16.7%, respectively). The second most common virus in patients with PCa was HSV-6 (20.0%), which was not detected in any men with BPH (p=0.003). There was a trend toward higher prevalence of CMV among patients with PCa (16.0% vs. 4.2%), but the difference was not significant (p=0.09). There was no association of viral infection with clinical and morphological features. CONCLUSIONS: The resulting trend toward a higher prevalence of HSV-6 and CMV in patients with PCa compared to those with BPH creates the prerequisites for further study of viruses in prostate diseases involving a larger cohort, which will provide an idea of the multi-stage process of malignant transformation and, possibly, open new therapeutic options for prevention and treatment.

PURPOSE: The aim of this study was to assess the mens androgen status influence on the severity and outcomes (transfer of patients to the ICU or death) of COVID-19 required hospital hospitalization. MATERIALS AND METHODS: The study included 151 hospitalized men with a confirmed diagnosis of COVID-19. To measure the severity of disease have been used Symptomatic Hospital and Outpatient Clinical Scale for COVID-19 (SHOCS-COVID). It includes the severity of the clinical condition (hyperthermia, shortness of breath, oxygen saturation, need for ventilation), the degree of inflammation (CRP), markers of thrombosis (D-dimer), the degree of lung damage according to CT. The patients underwent a study of full blood count, some biochemical parameters, lung CT, and a study of testosterone (T) and dihydrotestosterone (DHT) levels. RESULTS: T deficiency was observed in 46.4% of patients (70/151 men). At the same time, DHT deficiency was observed only in 14.4% of patients (18/125 men). In patients with a T level below the median, there was a significant increase in inflammatory factors (CRP, lymphocytes/CRP index), markers of thrombosis (D-dimer and fibrinogen), extensive lung damage at admission according to CT 25.75% vs. 11.95% (p<0.001), the elevated number of points for SHOCKS-COVID 7 (IQR 5-10) versus 5 (IQR 3-7) (p<0.001) and the longer duration of hospital treatment (3 days difference, p<0.001) in comparison with a group of patients with a T level above the median. At the same time, the T level had no correlation with age. The level of DHT had a weak inverse correlation with the age of patients, but not with the main markers of the severity of COVID-19, including the number of SHOCK-COVID scores. During multivariate regression analysis, it was shown that SHOCKS-COVID is the most significant predictor of admission to the ICU while no association of T and DHT levels with outcomes in COVID-19 was found. However, it was found that the concentration of T, even adjusted for age, has a significant inverse association with the severity of the course of the disease and the number of SHOCK-COVID scores (p=0.041). An analysis of the evaluation of directed acyclic graphs suggests the main role of COVID-19 severity in reducing androgenic function and T concentration, at which its anti-inflammatory effects are lost. There were no correlations between the concentration of DHT and the number of SHOCK-COVID scores and the COVID-19 prognosis. CONCLUSION: SHOCK-COVID is the most sensitive predictor of the COVID-19 outcome in hospitalized men, including adjusting to age. T and DHT do not directly affect the outcomes of the disease. The greater severity of the infection and an increase in SHOCK-COVID scores are associated with a decrease in the concentration of T, and a weakening of its anti-inflammatory and anti-cytokine effects, which indirectly worsens the prognosis of male patients with a new coronavirus infection undergoing hospital treatment. There are no such relationships for DHT.

PURPOSE: Assessment of COVID-19 incidence and hospitalization rate of male patients with prostatic hyperplasia depending on the intake of 5-alpha-reductase inhibitors (5-ARI). MATERIALS AND METHODS: In our study, electronic medical records of 1678 patients with prostatic hyperplasia were analyzed. 1490 men aged 71 (64-76) years were selected for final analysis. Vaccination against COVID-19 was carried out in 730 patients (49%). Treatment with 5-ARI inhibitors was carried out in 269 (18.1%) patients. RESULTS: Among 1490 included patients 790 (53%) had COVID- 19 while 360 (45.7%) of them required hospitalization. During the multivariate analysis, only two factors were associated with the risk of COVID-19 in the cohort studied: vaccination (odds ratio (OR) =0.095; 95% confidence interval (CI) 0.074-0.122), i.e. a 90.5% chance reduction, p<0.001) and the fact of taking 5-ARI (OR=0.235; 95%CI=0.165-0.335; p<0.001), i.e. a 76.5% chance reduction. The duration of 5-ARI therapy was not associated with the incidence of new coronavirus infection. The severe course of COVID-19 which required hospitalization was positively associated with age (p=0.025) and the presence of coronary artery disease (p=0.004); and negatively associated with the frequency of vaccination (p<0.001) and treatment of 5-ARI (3.1% vs. 11.6%, p<0.001). In a multivariate analysis of outpatient patients with prostatic hyperplasia who had COVID-19, 5-ARI intake (OR=0.240; 95% CI 0.122-0.473; p<0.001) and vaccination (OR = 0.570; 95% CI 0.401-0.808; p=0.002). The factors associated with increased chances of hospitalization due to the severe course of COVID-19 were coronary heart disease (+43.8%, p=0.019) and older age (+1.7% by one year, p=0.046). CONCLUSION: Taking 5-ARI, along with vaccination in patients with prostatic hyperplasia is a protective factor for morbidity and the severity of COVID-19.

OBJECTIVE: Clinical approbation of previously obtained normative criteria for evaluating erectograms using the Androscan MIT hardware complex, as well as comparing the monitoring indicators of nocturnal penile tumescence (NPT) with the results of the standard questionnaire International Index of Erectile Function-15 (IIEF-15). MATERIALS AND METHODS: The study included 120 patients aged 19 to 72 years. Erectile function was assessed using the IIEF-15 questionnaire and the Androscan MIT hardware complex. To assess erectile function, previously developed normative criteria for the relative increase in the diameter of the penis (OP) and the duration of NTP were used. Statistical data processing was carried out using the STATISTICA 12 software. A systematic literature search on the normative criteria for monitoring NTP was carried out in the Medline database. RESULTS: After performing androscanning, patients were divided according to the degree of ED: there were 12 patients without ED, 58 patients with grade 1 ED, 27 patients with grade 2 ED, and 23 patients with grade 3 ED. According to the results obtained, a positive correlation was found between the OD value and the results of the IIEF-15 questionnaire. CONCLUSION: The obtained data on the correlation between the results of the IIEF -15 questionnaire and the NTP monitoring parameters are consistent with most of the currently available foreign data.

OBJECTIVE: Analysis of androgen status in men hospitalized with a moderate COVID-19 and its relationship with the severity of the disease. MATERIALS AND METHODS: The study included 152 males with a confirmed diagnosis of COVID-19 based on the results of a positive PCR for the SARS-CoV-2 virus and/or computed tomography of the lungs hospitalized at the MSU University Clinic due to the moderate and severe COVID-19. Examination of the level of biochemical blood parameters (CRP, creatinine, urea, glucose, total testosterone (T)); CT of the lungs. To objectify the severity of the clinical symptoms, the NEWS2 distress syndrome severity scales and the original scale for assessing the clinical condition of patients with COVID 19 (SHOCS-COVID) were used. RESULTS: The median T level in 152 examined patients was 2.14 [1.21; 3.40] ng/ml. In patients with a T level below the median, the CRP level was more than two times higher, and the D-dimer value was almost two times higher than in patients with T level above median. The duration of treatment in the hospital was longer in men with COVID 19 and an initial T level below the median than in patients with T about the median (13 days vs 10.5 days, p=0.003). Low T level was correlated with lung damage by lung CT. After improving the clinical condition, there was a linear increase in the level of T independent of its initial level. CONCLUSION: Among men with moderate and severe COVID-19, a decreased testosterone level is detected in 46.7% of cases. Patients with low testosterone levels on admission have more severe COVID-19. A significant increase in testosterone level was observed after successful COVID-19 treatment without any special action regarding testosterone level.

OBJECTIVE: a systematic review of the available literature sources about criteria for nocturnal penile tumescences (NPT) registration, as well as the development our own criteria for evaluating erectograms obtained from Androscan "MIT" software complex. MATERIALS AND METHODS: a systematic search about NPT criteria was conducted in the Medline database. A PRISMA flowchart was used to visually represent the design of the study. The necessary calculations were carried out using the STATISTICA 12 software. RESULTS: Normal erectile function is characterized by a relative increase in penis diameter (RIn) of 30% or more with the duration of such NPTs of more than 60 minutes. For a mild ED in the case of a good RIn (30% or more) with a duration of NPT with such RIn less than 10 minutes (the time of 1 effective erection), it is advisable to determine the duration of the NPT with a RIn of 20% or more. If RIn is less than 30% it is advisable to use the duration of sufficient erections (with a relative increase in diameter of 20% or more) and the border value in this case is 60 minutes or more. Severe ED is characterized by RIn less than 20% or duration of NPT of less than 10 minutes with any RIn. CONCLUSION: at the moment there are no uniform criteria for the diagnosis of ED using the Androscan "MIT" software complex. As part of the unification of ED diagnostics we first introduced the terms of "effective erection", "sufficient erection", "relative increase" and also developed regulatory criteria and an algorithm for evaluating erectograms which will ensure continuity as well as the possibility of comparison of the results from different research groups.

The development and widespread implementation of modern endourological procedures for the treatment of benign prostatic hyperplasia (BPH) has led to a significant reduction in postoperative complications, but these interventions are associated to an increase of bladder neck contracture (BNC) rate. Various data on the frequency, pathogenesis, and risk factors for the development of BNC after endourological interventions are presented in the literature review. The prevalence of BNC after transurethral procedures depending on the type of energy used reaches up to 10%. Risk factors of BNC included the presence of chronic prostatitis and urinary tract infections, as well as small volume BPH. The age, cardiovascular diseases, type 2 diabetes, obesity, and a long-term smoking are considered as additional risk factors. A detailed study of the risk factors for BNC will further minimize BNC rate after transurethral procedures, thus improving the quality of life of patients.
