The effectiveness of tamsulosin hydrochloride with terazosin combination therapy for chronic prostatitis Type-III b

Objectives: To study the therapeutic effects of combined tamsulosin hydrochloride and terazosin treatment for patients with chronic prostatitis Type-III b. Methods: This study involved 180 patients with chronic prostatitis Type-III b treated between January 2018 and December 2020 conducted at Nanhua Hospital Affiliated to Nanhua University. Patients were randomly divided into two equal groups: one receiving oral terazosin hydrochloride tablets only (control group), and one orally receiving both tamsulosin hydrochloride sustained-release tablets and terazosin hydrochloride tablets (observation group). Outcome measurements included symptom scoring, inflammatory cytokine levels, as well as white blood cell and lecithin body counts in the prostatic fluid. Results: After 30 days of treatment, the observation group showed greater treatment effectiveness (86.67% vs. 73.33%, P<0.05). QLS, USS, PS, and NIH-CPSI symptom scores were lower in the observation group than the control group (P<0.05). No differences in adverse event distribution and incidence were noted. EPS IL-2 increased more in the observation group, while PGE-2, MIP-1α, and MIP-2 decreased more in the observation group. WBC levels decreased more in the observation group, while lecithin body levels increased more in the observation group. Conclusion: The combination of tamsulosin hydrochloride and terazosin for the treatment of patients with chronic prostatitis Type-III b has a significant effect. This approach reduced patient symptoms, lowered inflammatory biomarkers, and generally improved quality of life. This approach appears to have clinical value worthy of future investigation. doi: https://doi.org/10.12669/pjms.38.3.4931 How to cite this:Duan B, Wang X.

Direct N-Glycosylation Profiling of Urine and Prostatic Fluid Glycoproteins and Extracellular Vesicles

Expressed prostatic secretions (EPS), also called post digital rectal exam urines, are proximal fluids of the prostate that are widely used for diagnostic and prognostic assays for prostate cancer. These fluids contain an abundant number of glycoproteins and extracellular vesicles secreted by the prostate gland, and the ability to detect changes in their N-glycans composition as a reflection of disease state represents potential new biomarker candidates. Methods to characterize these N-glycan constituents directly from clinical samples in a timely manner and with minimal sample processing requirements are not currently available. In this report, an approach is described to directly profile the N-glycan constituents of EPS urine samples, prostatic fluids and urine using imaging mass spectrometry for detection. An amine reactive slide is used to immobilize glycoproteins from a few microliters of spotted samples, followed by peptide N-glycosidase digestion. Over 100 N-glycan compositions can be detected with this method, and it works with urine, urine EPS, prostatic fluids, and urine EPS-derived extracellular vesicles. A comparison of the N-glycans detected from the fluids with tissue N-glycans from prostate cancer tissues was done, indicating a subset of N-glycans present in fluids derived from the gland lumens. The developed N-glycan profiling is amenable to analysis of larger clinical cohorts and adaptable to other biofluids.

Effect of COVID-19 on Male Reproductive System – A Systematic Review

BackgroundAngiotensin-converting enzyme II (ACE2), a receptor for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) to enter host cells, is widely expressed in testes and prostate tissues. The testis and prostate produce semen. At present, there are contradictory reports about whether SARS-CoV-2 can exist in the semen of infected men.ObjectiveTo provide a comprehensive overview of the topic of whether COVID-19 can impact on male reproductive system.MethodsWe reviewed the relevant publications on the possible impact of Coronavirus Disease 2019 (COVID-19) on male reproductive system and summarized the latest and most important research results so far. Literature published in English from December 2019 to January 31, 2021 regarding the existence of SARS-CoV-2 in semen, testis, and prostatic fluid and the effects of COVID-19 on male reproductive were included.ResultsWe identified 28 related studies, only one of which reported the presence of SARS-CoV-2 in semen. The study found that the semen quality of patients with moderate infection was lower than that of patients with mild infection and healthy controls. The impaired semen quality may be related to fever and inflammation. Pathological analysis of the testis/epididymis showed that SARS-CoV-2 viral particles were positive in 10 testicular samples, and the spermatogenic function of the testis was impaired. All 94 expressed prostatic secretion (EPS) samples were negative for SARS-CoV-2 RNA.ConclusionThe likelihood of SARS-CoV-2 in the semen of COVID-19 patients is very small, and semen should rarely be regarded as a carrier of SARS-CoV-2 genetic material. However, COVID-19 may cause testicular spermatogenic dysfunction via immune or inflammatory reactions. Long-term follow-up is needed for COVID-19 male patients and fetuses conceived during the father’s infection period.

Reproductive and endocrinological effects of Benign Prostatic Hyperplasia and finasteride therapy in dogs

Benign prostatic hyperplasia (BPH) is one of the most important reproductive disorders in aging dogs. Therapeutic measures include orchiectomy and pharmacological treatment, leading to reduction of prostate volume and clinical signs. One of the most common drugs used in BPH treatment is finasteride, but data regarding its possible side effects are scarce. Thus, the aim of this study was to evaluate the effects of BPH and short-term (2 months) finasteride therapy on clinical, endocrinological, and reproductive parameters in dogs. Dogs were allocated into four experimental groups: Non-affected (n = 5), BPH (n = 5), Non-Affected-Finasteride (n = 5) and BPH-Finasteride (n = 5) groups. Dogs were evaluated monthly during 2 months by a complete breeding soundness examination, B-mode ultrasound and Doppler ultrasonography of the testicular artery, hormonal profile (testosterone, estrogen and dihydrotestosterone) and oxidative profile of the prostatic fluid. After 2 months, dogs were gonadectomized and testicles were subjected to histologic analysis. Finasteride treatment reduced dihydrotestosterone concentrations, without negative influence on semen quality and also reverted testicular hemodynamics changes of BPH. On the other hand, BPH was accompanied by significant changes in testosterone and estrogen concentrations and semen quality, mainly related to sperm kinetics alterations. In conclusion, BPH dogs have important hormonal and sperm alterations, however, short-term finasteride treatment (2 months) was able to reduce overall effects of BPH, thus representing a method of therapy for BPH treatment.

The efficacy of Adenoprosin® in combined treatment of patients with chronic bacterial prostatitis

Background. Chronic bacterial prostatitis is a common disease clinically diagnosed based on signs of inflammation and the presence of infection in the prostatic fluid. Standard antibiotic therapy in most cases does not lead to a decrease in the number of recurrences. In this connection, an integrated approach is often used in therapy, and in addition to antibacterial therapy, biostimulators, extracts of various plants and animals are prescribed. One of the main advantages of these prescriptions is that the drugs have minimal side effects.Objective. To assess the effectiveness of the use of Adenoprosin® in the combined treatment of patients with chronic bacterial prostatitis.Material and methods. 60 patients aged from 24 to 50 years old (average age is 31.3 ± 2.8 years) with a diagnosis of chronic bacterial prostatitis were examined and treated, the duration of the disease ranged from 6 months to 15 years (average duration of the disease is 1.5 ± 0.3 years). The patients were divided into two groups: group I included 30 patients who were treated with antibacterial drugs and Adenoprosin®, group II included 30 patients who were treated with antibacterial drugs only. The course of treatment lasted 30 days, the total time of observation of the patients was 3 months. Clinical control was carried out at the first visit to the urologist, on the 14th, 28th, 45th and 90th days from the start of therapy and included filling out the following: The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), The International Prostate Symptom Score (IPSS) and Quality of Life (QoL), as well as the International Index of Erectile Function (IIEF-5) questionnaire in order to identify the possible effect of therapy on sexual function.Results. The analysis revealed that the use of the Adenoprosin® in complex therapy in patients with chronic bacterial prostatitis reduces the overall score of the NIH-CPSI questionnaire by an average of 4 points. When conducting a questionnaire at the end of treatment, 2 (6.6%) patients in the group II noted dissatisfaction with the therapy, on the 90th day of observation, complaints of dissatisfaction with the treatment remained in 1 (3.3%) patient. In 5 (16.6%) patients of the group II, against the background of the therapy, there was no subjective improvement in the treatment; on the 90th day of observation, the number of unsatisfied patients remained the same. Analysis of the results of microscopy of the prostatic fluid and microflora after treatment on day 28 showed the decrease in the content of leukocytes in the group I patients – less than 10 leukocytes in the field of vision in 25 (80%) patients, which was higher in comparison with patients of the group II – 21 (70%). In 5 (16.6%) patients of the group I, the number of leukocytes in the prostatic fluid was in the range of 10–20 in the field of view, all patients had previously had recurrent forms of the disease. The number of leukocytes more than 10, after antibacterial therapy in the group II, was in 7 (23.3%) patients, of them 5 (16.6%) patients had recurrent forms of the disease, and 2 (6.6%) patients were diagnosed with prostatitis for the first time. Thus, the use of combination therapy in the group I, to a greater extent, reduced the inflammatory markers of the disease.Conclusion. The Adenoprosin® in complex therapy has a proven anti-inflammatory effect on the prostate gland, reduces the pain rapidly, decreases the total score of prostatic symptoms when analyzing the NIH-CPSI questionnaires, improves erectile function, reduces markers of inflammation in the pre-fetal gland and can be recommended for patients with chronic bacterial inflammation in the prostate gland.
