Show summary
This paper presents the results of a pilot study of difficult-to-treat patients (exhibiting several previous treatment failures or detection of extended-spectrum beta-lactamase [ESBL] strains) with chronic bacterial prostatitis (CBP) who underwent treatment with fosfomycin trometamol (FT) and N-acetyl-L-cysteine (NAC). Twenty-eight patients with clinically- and microbiologically-confirmed CBP who attended a single urological institution between January 2018 and March 2019 were treated with oral administration of 3 g FT once a day for 2 days, followed by a dose of 3 g every 48 h for 2 weeks, in combination with oral administration of NAC 600 mg once a day for 2 weeks. Clinical and microbiological analyses were carried out at the time of admission (T0) and during follow-up at 1 month (T1) and 6 months (T2) after the end of treatment. Symptoms were assessed by the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and International Prostatic Symptom Score (IPSS), and quality of life was assessed by Quality of Well-Being (QoL) questionnaires. Isolated strains were Escherichia coli (23 patients), Enterococcus spp. (3 patients), and Klebsiella oxytoca (2 patients). ESBL strain was found in 19 (67.8%) patients. Microbiological eradication was documented in 21 (75%) patients at the second follow-up visit and clinical cure was achieved in 20 (71.4%) patients. Significant changes on questionnaires were recorded between baseline and follow-up visits. Fifteen of 19 patients (78.9%) with ESBL strains were cured. No significant side effects were reported. FT in combination with NAC is a promising alternative therapy in difficult-to-treat CBP patients.

Introduction The genomic revolution has transformed our understanding of urinary tract infection. There has been a paradigm
shift from the dogmatic statement that urine is sterile in healthy people, as we are becoming forever more familiar with the
knowledge that bacterial communities exist within the urinary tracts of healthy people. Metagenomics can investigate the
broad populations of microbial communities, analysing all the DNA present within a sample, providing comprehensive data
regarding the state of the microenvironment of a patient’s urinary tract. This permits medical practitioners to more accurately
target organisms that may be responsible for disease—a form of ‘precision medicine’.
Methods and Results This paper is derived from an extensive review and analysis of the available literature on the topic of
metagenomic sequencing in urological science, using the PubMed search engine. The search yielded a total of 406 results,
and manual selection of appropriate papers was subsequently performed. Only one randomised clinical trial comparing
metagenomic sequencing to standard culture and sensitivity in the arena of urinary tract infection was found.
Conclusion Out of this process, this paper explores the limitations of traditional methods of culture and sensitivity and
delves into the recent studies involving new high-throughput genomic technologies in urological basic and clinical research,
demonstrating the advances made in the urinary microbiome in its entire spectrum of pathogens and the first attempts of
clinical implementation in several areas of urology. Finally, this paper discusses the challenges that must be overcome for
such technology to become widely used in clinical practice.
