[Taxonomic characteristics and antibiotic susceptibility of microorganisms verified in the expressed prostate secretion in post-COVID-19 patients with recurrent chronic bacterial prostatitis].

INTRODUCTION: Recurrent chronic bacterial prostatitis (rCBP) is a hard-to diagnosis-and-treat disease which there is no consensus. A particularly difficult cohort is represented by patients who had COVID-19. The study aimed to evaluate the taxonomic structure and sensitivity to antibacterial drugs of microorganisms verified in expressed prostate secretion (EPS) in rCBP-patients who had COVID-19. MATERIALS AND METHODS: A multicenter, prospective, randomized study was conducted with the inclusion of 52 rCBP patients who had COVID 19, in which the taxonomic structure and susceptibility were studied to antibacterial drugs of microorganisms that were verified and dominated in the EPS. Bacteriological study was carried out using an extended set of selective nutrient media and special cultivation conditions. Antibiotic susceptibility was determined in the taxa of microbiota dominating in the EPS. RESULTS: The mean age of the patients was 34.8+/-5.2 years, the duration of rCBP was 5.7+/-2.3 years. In all patients, various variants of aerobic-anaerobic compositions of microorganisms were recorded in the life cycle. A total of 27 microbiota taxa were isolated. The aerobic cluster was represented by 16 genera and/or species, the anaerobic cluster by 11. When studying antibiotic susceptibility to antibacterial drugs, an increase in antibiotic resistance of the most microorganisms isolated was revealed. CONCLUSIONS: The taxonomic structure of microorganisms in rCBP-patients who had COVID-19 in all cases was characterized by complex and new variants of aerobic-anaerobic associations of microorganisms. When studying the antibiotic susceptibility, multi-resistant and pan-resistant bacteria were identified that is a real threat to this category of patients.

[Serum testosterone and testicular hemodynamics before and after infection with SARS-COV-2 (pilot study)].

INTRODUCTION: The current epidemiological situation dictates a detailed study of the effect of a new coronavirus infection (SARS-CoV-2) on various anatomical, histological, physiological and biochemical parameters of the human body, which has become an integral part of many medical research, including urology, andrology, endocrinology. OBJECTIVE: To study serum testosterone levels and testicular hemodynamics before and after infection with SARS-CoV-2. MATERIALS AND METHODS: 20 patients were examined, before and after suffering SARS-CoV-2 infection (who fell ill at the beginning of 2020). Average age 37.8 years (min=27, max=50). The level of total testosterone (s) in the blood serum and hemodynamic parameters of the testicles (maximum and minimum blood flow velocity and resistance index) were studied. RESULTS: When studying the level of s 3 months after the transferred SARS-CoV-2, its decrease from the initial value was noted (r=0.47; p=0.35), and after 6 months (r=0.98; p<0.007) there was no recovery of the target level of Ts before infection with SARS-CoV-2. Regarding the hemodynamics of the testicles, there was also a decrease in Vmax and Vmin, and an increase in RI, which indicates a deterioration in the blood flow of the testicles (p<0.001). CONCLUSION: SARS-CoV-2 affects the level of Ts in the blood serum and the parameters of the hemodynamics of the testicles. The extent to which SARS-CoV-2 affects patient performance depends largely on the severity of the disease and to a lesser extent on baseline performance.
