RESUMO

OBJECTIVES: The increasing incidence of fluoroquinolones (FQ) resistance may lower its efficacy in preventing UTI following transrectal ultrasound-guided prostate biopsy (TRUS-PB). We assessed the efficacy and safety of FQ and fosfomycin-trometamol (FT) in patients undergoing TRUS-PB. METHODS: A prospective observational study was conducted between April 2017 and June 2019 and enrolled men undergoing TRUS-PB and receiving a single-dose of FQ (FQ-arm) or FT (FT-arm) for UTI prophylaxis per physician's choice. The primary efficacy endpoint was self-reported TRUS-PB UTI. We assessed baseline factors associated with UTI with logistic regression. RESULTS: A total of 222 men were enrolled, 141/222 (64%) received FQ, and 81/222 (36%) FT. The median age was 67.6 years [IQR, 61.4-72.1] and the Charlson score was 3 [IQR, 3-5]. The overall incidence of self-reported TRUS-PB UTI was 12% (24/197, (95%CI, 8%-17%)): 15% (17/116, (95% CI, 10%-17%)) in FQ-arm, versus 9% (7/81, 95% CI (5%-13%)) in FT-arm (RR = 0.55 (95% CI, 0.22-1.40), p-value = 0.209). No baseline characteristic was significantly associated with TRUS-PB UTI. Safety was similar between the arms: the rate of the reported adverse event was 31% (36/116, (95% CI, 25%-37%) in the FQ-arm versus 36% (28/81, (95% CI, 28%-41%)) in the FT-arm (RR = 1.17 (95% CI, 0.64-2.15), p = 0.602). CONCLUSIONS: TRUS-PB UTI prophylaxis with FT and FQ has similar efficacy and safety. A randomized comparison of these two antibiotics is warranted.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Hyperplasia, Tumors and cancers are various forms of proliferative disorders affecting humans. Surgery is the main treatment approach while other options are also associated with adverse effects. There is therefore a need for the development of better alternative therapy that is cost effective and readily available with little or no adverse effect. Some bioactive agents in medicinal plants exhibit their anti-proliferative potential by induction of mitochondrial permeability transition pore (mPT) opening. Gloriosa superba, a medicinal plant, is folklorically used in the treatment of tumors and cancers. AIM OF THE STUDY: This study therefore aimed at investigating the effect of ethanol leaf extract of Gloriosa superba (EEGS) on mPT and monosodium glutamate-induced proliferative disorder in some specific tissues using rat model. MATERIALS AND METHODS: Isolated rat liver mitochondria were exposed to different concentrations (10, 30, 50, 70 and 90 µg/ml) of EEGS. The mPT pore opening, cytochrome c release, mitochondrial ATPase activity and lipid peroxidation were assessed spectrophotometrically. Caspases 9 and 3 activities were carried out using ELISA technique. Histological assessment of the liver, prostate and uterus of normal and monosodium glutamate (MSG)-treated rats were carried out. RESULTS: The results showed significant induction of mPT pore opening, release of cytochrome c, enhancement of mitochondrial ATPase activity, inhibition of lipid peroxidation and activation of caspases 9 and 3 activities by EEGS. The histological assessment revealed the presence of MSG-induced hepato-cellular damage, benign prostate hyperplasia and uterine hyperplasia which were ameliorated by EEGS co-administration. CONCLUSIONS: These findings suggest that EEGS contains putative agents that can induce apoptosis via induction of mPT pore opening and as well protect against MSG-induced hepato-cellular damage and proliferative disorder in prostate and uterus.

RESUMO

BACKGROUND: Obesity has become an increasingly worrisome reality. A very-low-calorie ketogenic diet (VLCKD) represents a promising option by which to achieve significant weight loss. This study sought to evaluate the effectiveness of VLCKD on metabolic parameters and hormonal profiles of obese male patients. METHODS: We enrolled 40 overweight/obese men who consumed VLCKD for at least eight weeks. Body weight, waist circumference, fasting glucose, insulin, total cholesterol, high-density lipoprotein, triglycerides, creatinine, uric acid, aspartate aminotransferase, alanine aminotransferase, vitamin D, luteinizing hormone (LH), total testosterone (TT), and prostate-specific antigen (PSA) were calculated before and after VLCKD consumption. We additionally determined the homeostasis model assessment index and low-density lipoprotein (LDL) values. RESULTS: After VLCKD (13.5 ± 0.83 weeks), the mean body weight loss was 21.05 ± 1.44 kg; the glucose homeostasis and lipid profile were improved significantly; serum vitamin D, LH, and TT levels were increased and the PSA levels were decreased significantly as compared with pretreatment values. These results are of interest since obesity can lead to hypogonadism and in turn, testosterone deficiency is associated with impaired glucose homeostasis, metabolic syndrome, and diabetes mellitus. Moreover, a close relationship between obesity, insulin resistance, and/or hyperinsulinemia and increased prostate volume has been reported, with a consequent greater risk of developing lower urinary tract symptoms. CONCLUSIONS: VLCKD is an effective tool against obesity and could be a noninvasive, rapid, and valid means to treat obese patients with metabolic hypogonadism and lower urinary tract symptoms.

RESUMO

BACKGROUND: There is variable reporting on the benefits of a 200 µg/d selenium supplementation towards reducing prostate cancer impacts. The current analysis is to understand whether stratified groups receive supplementation benefits on prostate health. METHODS: 572 men were supplemented with 200 µg/d selenium as selinized yeast for six months, and 481 completed the protocol. Selenium and prostate-specific antigen (PSA) levels were measured in serum at pre- and post-supplementation. Changes in selenium and PSA levels subsequent to supplementation were assessed with and without demographic, lifestyle, genetic and dietary stratifications. RESULTS: The post-supplementation selenium (p = 0.002) and the gain in selenium (p < 0.0001) by supplementation were significantly dependent on the baseline selenium level. Overall, there was no significant correlation between changes in PSA and changes in selenium levels by supplementation. However, stratified analyses showed a significant inverse correlation between changes in PSA and changes in selenium in men below the median age (p = 0.048), never-smokers (p = 0.031), men carrying the GPX1 rs1050450 T allele (CT, p = 0.022 and TT, p = 0.011), dietary intakes above the recommended daily intake (RDI) for zinc (p < 0.05), and below the RDI for vitamin B12 (p < 0.001). CONCLUSIONS: The current analysis shows the influence of life factors on prostate health benefits of supplemental selenium.

RESUMO

In recent years, the progress of science and medicine greatly has influenced human life span and health. However, lifestyle habits, like physical activity, smoking cessation, moderate alcohol consumption, diet, and maintaining a normal body weight represent measures that greatly reduce the risk of various diseases. The type of diet is very important for disease development. Numerous epidemiological clinical data confirm that longevity is linked to predominantly plant-based diets and it is related to a long life; whereas the western diet, rich in red meat and fats, increases the risk of oxidative stress and thus the risk of developing various diseases and pre-aging. This review is focused on the bioavailability of polyphenols and the use of polyphenols for the prevention of prostate diseases. Special focus in this paper is placed on the isoflavonoids and flavan-3-ols, subgroups of polyphenols, and their protective effects against the development of prostate diseases.

RESUMO

We investigated the clinical effectiveness and safety of tazobactam/piperacillin (TAZ/PIPC) in a 1:8 ratio, a ß-lactamase inhibitor with penicillin antibiotic, for the prevention of febrile infectious complication after prostate biopsy. Each patient received a single dose of TAZ/PIPC 4.5 g, 30 min before the biopsy in Group 1 or TAZ/PIPC 4.5 g twice, once 30 min before and once after the biopsy (just before discharge or 5 h after the biopsy), in Group 2. Estimation of efficacy was performed within 1-month after prostate biopsy. Clinical diagnosis of febrile infectious complication was based on a body temperature elevation greater than 38 °C. Infectious complication after prostate biopsy was detected in 2.5% (4/160 patients) in Group 1 and in 0.45% (2/442 patients) in Group 2. All of the patients with febrile infectious complication had risk factors: 5 patients had voiding disturbance, 2 patients had diabetes mellitus and 1 patient had steroid dosing. In group 1, 88 patients had at least one risk factor and 72 patients had no risk factors. Of the patients with a risk factor, 4 had febrile infectious complication after prostate biopsy, but there was no significant difference between the two groups. In group 2, 87 patients had at least one risk factor and 255 patients had no risk factors. The patients with a risk factor had febrile infectious complication significantly more frequently than did patients without a risk factor (P = 0.038). Therefore, TAZ/PIPC appears to be effective as preoperative prophylaxis against the occurrence of febrile infectious complication after prostate biopsy.

RESUMO

BACKGROUND: To describe a preparatory protocol for prostate biopsy consisting of prophylaxis based on a third-generation cephalosporin and suppository-type povidone-iodine. METHODS: From January 2004 to May 2012 we reviewed infective complications in 1,684 patients who underwent transrectal ultrasound (TRUS)-guided prostate biopsy. All of the patients received prophylactic antibiotics through a single intravenous injection of a third-generation cephalosporin and cefixime at 100 mg PO for 5 d, with this regimen begun before biopsy, and were also given gynobetadine in a dose of 200 mg just before biopsy. Infectious complications were classified as sepsis, fever (>38°C) without sepsis, and other clinical manifestations of infection. To evaluate the bactericidal effects of gynobetadine, we counted bacterial colonies prospectively in cultures of rectal swab specimens from 150 patients who underwent TRUS-guided prostate biopsy. RESULTS: Complications occurred in 46 of the patients (2.73%), including infective complications in 11 (0.65%) patients and non-infective complications in 35 (2.08%) patients. Of the patients with infective complications, two had fever without sepsis, none had clinical urinary tract infections without fever, and none had sepsis. In prospective in vitro investigations, the mean bacterial colony count before rectal preparation with an enema or rectal insertion of povidone-iodine suppository was 2.38×10(6), whereas the colony count after a povidone-iodine rectal enema and subsequent biopsy was 1.81×10(3) and the colony count after rectal preparation with povidone-iodine suppository and subsequent biopsy was 8.1×10(2) (all p<0.001). CONCLUSIONS: The administration of cephalosporin-based prophylactic antibiotics and the simple use of suppository-type povidone-iodine provided an excellent protocol for reducing infective complications of TRUS-guided prostate biopsy. The simplicity of use and cost effectiveness of gynobetadine were noteworthy.

RESUMO

The present study was performed to determine the effects of different antioxidants on testicular histopathology and oxidative damage induced by cadmium (Cd) in rat testis and prostate. Twenty five rats were equally divided into five groups (n = 5/group). The control group was injected subcutaneously with saline while the Cd alone treated group received a subcutaneous injection of 0.2 mg/kg CdCl(2). Other groups were treated with sulphoraphane (25 µg/rat), vitamin E (75 mg/kg), and Ficus Religiosa plant extract (100 mg/kg) orally along with subcutaneous injections of 0.2 mg/kg CdCl(2) for fifteen days. Oxidative damage in the testicular and prostate tissues were assessed by the estimation of catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), and glutathione reductase (GSR) activity. Lipid peroxidation (TBARS), protein estimation, and histomorphology were also assessed. Cadmium exposure caused a significant decrease in antioxidant enzymes like CAT, POD, SOD, GSR, protein concentrations, and a marked increase in TBARS activity in rat testis and prostate. Histological examination of adult male rat testes showed a disruption in the arrangement of seminiferous tubules along with a reduction in the number of germ cells, Leydig cells, tunica albuginea thickness, diameter of seminiferous tubules, and height of germinal epithelium. Co-treatment with vitamin E, sulphoraphane, and Ficus religiosa were found to be effective in reversing Cd induced toxicity, representing potential therapeutic options to protect the reproductive tissues from the detrimental effects of Cd toxicity.

RESUMO

Despite recent advances in understanding the biological basis of prostate cancer (PCa), the management of this disease remains a challenge. Chemoprotective agents have been used to protect against or eradicate prostate malignancies. Here, we investigated the protective effect of γ-tocopherol on N-methyl-N-nitrosourea (MNU)-induced epithelial dysplasia in the rat ventral prostate (VP). Thirty-two male Wistar rats were divided into four groups (n = 8): control (CT): healthy control animals fed a standard diet; control+γ-tocopherol (CT+γT): healthy control animals without intervention fed a γ-tocopherol-enriched diet (20 mg/kg); N-methyl-N-nitrosourea (MNU): rats that received a single dose of MNU (30 mg/kg) plus testosterone propionate (100 mg/kg) and were fed a standard diet; and MNU+γ-tocopherol (MNU+γT): rats that received the same treatment of MNU plus testosterone and were fed with a γ-tocopherol-enriched diet (20 mg/kg). After 4 months, the VPs were excised to evaluate morphology, cell proliferation and apoptosis, as well as cyclooxygenase-2 (Cox-2), glutathione-S-transferase-pi (GST-pi) and androgen receptor (AR) protein expression, and matrix metalloproteinase-9 (MMP-9) activity. An increase in the incidence of epithelial dysplasias, such as stratified epithelial hyperplasia and squamous metaplasia, in the MNU group was accompanied by augmented cell proliferation, GST-pi and Cox-2 immunoexpression and pro-MMP-9 activity. Stromal thickening and inflammatory foci were also observed. The administration of a γ-tocopherol-enriched diet significantly attenuated the adverse effects of MNU in the VP. The incidence of epithelial dysplasia decreased, along with the cell proliferation index, GST-pi and Cox-2 immunoexpression. The gelatinolytic activity of pro-MMP-9 returned to the levels observed for the CT group. These results suggest that γ-tocopherol acts as a protective agent against MNU-induced prostatic disorders in the rat ventral prostate.

RESUMO

OBJECTIVE: To study the causes, clinical manifestations, treatment and prevention of calculus that develops in the prostatic cavity after transurethral resection of the prostate. METHODS: We reported 11 cases of calculus that developed in the prostatic cavity after transurethral resection or transurethral plasmakinetic resection of prostate. The patients complained of repeated symptoms of frequent micturition, urgent micturition and urodynia after operation, accompanied with urinary tract infection and some with urinary obstruction, which failed to respond to anti-infective therapies. Cystoscopy revealed calculi in the prostatic cavity, with eschar, sphacelus, uneven wound surface and small diverticula in some cases. After diagnosis, 1 case was treated by holmium laser lithotripsy and a second transurethral resection of the prostate, while the other 10 had the calculi removed under the cystoscope, followed by 1 -2 weeks of anti-infective therapy. RESULTS: After treatment, all the 11 cases showed normal results of routine urinalysis, and no more symptoms of frequent micturition, urgent micturition and urodynia. Three- to six-month follow-up found no bladder irritation symptoms and urinary tract infection. CONCLUSION: Repeated symptoms of frequent micturition, urgent micturition, urodynia and urinary tract infection after transurethral resection of the prostate should be considered as the indicators of calculus in the prostatic cavity, which can be confirmed by cystoscopy. It can be treated by lithotripsy or removal of the calculus under the cystoscope, or even a second transurethral resection of the prostate. For its prevention, excessive electric coagulation and uneven wound surface should be avoided and anti-infection treatment is needed.

RESUMO

Prostate problems, such as benign prostatic hyperplasia, prostatic intra-epithelial neoplasia, prostatitis, and prostate cancer have been recognized as problems largely related to androgens and genetic factors. They affect a large fraction of the elderly population, contributing significantly to morbidity and mortality. Estrogen has also now been recognized as one of the important regulators of prostate growth. Diet, general health, and obesity were disregarded as the causative or complicating factors until very recently. Increasing episodes of prostate problems, complications in overweight/obese individuals, or both have attracted attention toward these contemporary risk factors. Prostate problems are reportedly less frequent or less severe in areas in which a plant-based diet is predominant. Consumption of certain fatty acids, particularly of animal origin, has been correlated with increased prostate problems. As adipose tissue is increasingly being regarded as hormonally active tissue, high body fat and obesity need in-depth exploration to understand the associated risk of prostate problems. Adipose tissue is now known to affect circulating levels of several bioactive messengers and therefore could affect the risk of developing prostate problems in addition to several other well-recognized health problems. Nevertheless, increased plasma volume, excess tissue growth, and fat deposition could affect resection and number of biopsies required, thus adding further complications because of a delayed diagnosis. In short, evidence is gathering to support the influence of diet and obesity on prostate health. In this review article, we have tried to make this connection more apparent using supporting published data.

RESUMO

Dietary patterns play a role on prostatic diseases in association with genetic, behavioral, occupational and environmental ones. Data from reviewed literature provide evidences of a possible relationship between dietary habits and the incidence of prostate disorders, even if it is not enough to justify a widespread adoption of new dietary habits. In this review the role of dietary patterns, including the use of supplements, in the prevention and treatment of the most frequent and known prostatic diseases, benign prostatic hyperplasia (BPH) and prostate cancer (PC) was analyzed. A limited number of well designed trials were identified in which diet and dietary supplement intervention appeared to slow disease progression. Although conclusive evidences are limited, the current data suggest that a diet low in total calories and fat, high in vegetables and fruits and that body weight control could be possibly effective in preventing prostatic diseases. On the other hand care must be taken to ensure that over-consumption of dietary supplements does not occur because it may be harmful.

RESUMO

AIMS OF STUDY: Retinoid-mediated signal transduction plays a crucial role in the embryogenesis of various organs. We previously reported the successful induction of anorectal malformations in mice using retinoic acid (RA). Retinoic acid controls the expression of essential target genes for cell differentiation, morphogenesis, and apoptosis through a complicated interaction in which RA receptors form heterodimers with retinoid X receptors. In the present study, we investigated whether the retinoid antagonist, LE135, could prevent the induction of anorectal malformations (ARMs) in mice. METHODS: Retinoic acid was intraperitoneally administered as 100 mg/kg of all-trans RA on E9; and then the retinoid antagonist, LE135, was intraperitoneally administered to pregnant ICR strain mice on the eighth gestational day (E8), 1 day before administration of RA (group B) or on E9, simultaneously (group C) with RA administration. All of the embryos were obtained from the uteri on E18. Frozen sections were evaluated for concentric layers around the endodermal epithelium by hematoxylin and eosin staining. RESULTS: In group A, all of the embryos demonstrated ARM with rectoprostatic urethral fistula, or rectocloacal fistula, and all of the embryos showed the absence of a tail. In group B, 36% of the embryos could be rescued from ARM. However, all of the rescued embryos had a short tail that was shorter than their hind limb. The ARM rescue rates in group B were significantly improved compared to those in group A (P < .01). In group C, 45% of the embryos were rescued from ARM, but all of the rescued embryos had short tail. The ARM rescue rate in group C was significantly improved compared to that in group A (P < .01). However, there was no significant difference in the ARM rescue rate between group B and Group C. CONCLUSION: The present study provides evidence that in the hindgut region, RAR selective retinoid antagonist, LE135, could rescue embryos from ARM. However, the disturbance of all-trans RA acid was limited to the caudal region. Further study to establish an appropriate rescue program for ARM in a mouse model might suggest a step toward protection against human ARM in the future.

RESUMO

OBJECTIVE: • To examine the efficacy of adding amikacin to fluoroquinolone-based antimicrobial prophylaxis in preventing transrectal ultrasonography-guided prostate biopsy (TGB) associated infections. PATIENTS AND METHODS: • Infections after TGB were compared before adding amikacin to antimicrobial prophylaxis (2006) with those that occurred after adding amikacin to the prophylaxis (2007 and 2008). • During both periods antimicrobial prophylaxis consisted of ciprofloxacin, co-amoxiclav and metronidazole except after August 2008 when co-amoxiclav was discontinued. • Amikacin was added to the prophylaxis protocol in the period 2007 and 2008. RESULTS: • Before adding amikacin 11 of 281 (3.9%) patients developed infections after TGB (seven urinary tract infections (UTIs) and seven bacteraemias) whereas after adding amikacin six UTIs and two bacteraemias occurred in 590 (1.4%) patients. • In both periods, most of the strains causing the infections were ciprofloxacin resistant (2006: 13 of 14; 2007 and 2008: seven of eight). • Overall, there is strong statistical evidence that the total infection rate was significantly reduced after the inclusion of amikacin into the prostate biopsy prophylaxis regimen. • In 2007 and 2008 when amikacin was included in prophylaxis, the bacteraemia rate was reduced to just over one-tenth of the rate in 2006 before introducing amikacin (P= 0.002). • Although just failing to reach the conventional significance level of 0.05, the evidence suggests a reduction in UTI by an estimated 60% after adding amikacin. CONCLUSION: • We conclude that adding amikacin to fluoroquinolone-based antimicrobial prophylaxis in areas with high fluoroquinolone resistance confers significant benefit in preventing infections after TGB.

RESUMO

INTRODUCTION: Helicobacter pylori (H pylori) infection is a focus of attention nowadays. It has been found to cause gastrointestinal disorders and also extra-intestinal disorders. The aim of this paper is to explore the role of H pylori in urological diseases and to keep urologists up to date in this subject. MATERIALS AND METHODS: Medline and PubMed were searched from 1950 to December 2007 for the following combined terms: Helicobacter pylori together with urology, urological diseases, kidney, kidney cancer, ureter, bladder, bladder cancer, prostate, prostate cancer, benign prostatic hyperplasia, urethra, seminal vesicle, testis, and testicular cancer. RESULTS: Accumulating evidence is appearing in the literature relating H pylori infection to urological diseases. The most obvious is the implication of H pylori in inducing chronic cystitis leading to bladder lymphoma. In addition, some epidemiological studies have shown significant associations between infective chronic prostatitis and prostatic carcinoma. CONCLUSION: A simple hypothetical model relating H pylori infection to prostate and bladder diseases is proposed to stimulate the collaborative work between the urologists and scientists to explore this field which is underinvestigated to date. If H pylori is found to have a significant role in urological diseases, prevention of bladder and prostate cancers by eradication of H pylori infection may become a reality like what happened in the treatment of peptic ulcer disease and gastric cancer.
