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.
