Update on Prostatitis and Treatments BAUN Benign Study Day 14/03/2012 Mr Richard Cetti Specialist Registrar Urology, QA Portsmouth Prostatitis an Important Problem! Prevalence 2.2-13.8% Quality of life Economic Costs Prostatitis an Important Problem! ‘Pain management is a necessity in the work of each physician.’ F. Sauerbruch, 1936 Introduction Pain Classification/Terminology Presentation Investigation Treatment- historical, contemporary and the evidence The Future Pain -an unpleasant sensory and emotional experience Hypogastric Nerve Pelvic Nerves Pudendal Nerve Brain Ascending Syst Convergence Projection Theory (Ruch) Dorsal Horn Periphery Skin Viscus Chronic Pain Combination of: Neuroplasticity Central processing altered Trophic changes in subcutaneous tissue and muscle All site normal sensations become painful (allodynia). At site painful stimuli become more painful (hyperalgesia). Zone affected adjacent tissue (secondary hyperalgesia). Aetiology of Chronic Prostatitis - - Poorly understood Multiple factors within and between patients Hypotheses: Presence of antibiotic resistant non-culturable micro-organisms Chemical irritation Intra-ductal reflux and obstruction Dysfunctional high pressure voiding Neuropathic pain Pudendal nerve entrapment Autoimmune Classification Classification- NIH/EAU Cat Cat Cat Cat I II III IV Acute bacterial prostatitis Chronic bacterial prostatitis Prostate Pain Syndrome (CPPS) Asymptomatic inflammatory prostatitis Classification- NIH/EAU Cat I Cat II Acute bacterial prostatitis Chronic bacterial prostatitis Cat III Prostate Pain Syndrome (CPPS) Discomfort or pain in the pelvic region for at least 3 months with variable voiding and sexual symptoms, no demonstrable infection.

Antibiotics Ciprofloxacin, ofloxacin, levofloxacin ~10% patients will have culturable bacteria. J Urol. 2001 May;165(5):1539-44. Predictors of patient response to antibiotic therapy for the chronic prostatitis/chronic pelvic pain syndrome: a prospective multicenter clinical trial. Nickel JC et al. However, 57% of patients on ofloxacin saw improvement Trial 2 weeks and continue for 6 if benefit. Alpha-blockers Alfuzosin, Terazosin, Tamsulosin N Engl J Med. 2008 Dec 18;359(25):2663-73. Alfuzosin and symptoms of chronic prostatitis-chronic pelvic pain syndrome Nickel JC et al. Multicenter, randomized, double-blind, placebo-controlled trial of alfuzosin. 272 men were randomly assigned to treatment for 12 weeks with either 10 mg of alfuzosin/day or placebo. The primary outcome was a reduction of at least 4 points in the CPSI score. CPSI responders Placebo N=134 Alfuzosin N=138 66(49%) 68(49%) Anti-inflammatories Celecoxib, rofecoxib J Urol. 2003 Apr;169(4):1401-5. A randomized, placebo controlled, multicenter study to evaluate the safety and efficacy of rofecoxib in the treatment of chronic nonbacterial prostatitis. Nickel JC et al. Multicenter, randomized, double-blind, placebo-controlled trial of rofecoxib. 161 men were randomly assigned to treatment with either 25-50 mg of rofecoxib/day or placebo. Of the patients, 79% on 50 mg rofecoxib versus 59% on placebo reported no or mild pain. But not statistically significant. Neuropathic Painkillers Amitriptylline, Pregabalin Arch Intern Med. 2010 Sep 27;170(17):1586-93. Pregabalin for the treatment of men with chronic prostatitis/chronic pelvic pain syndrome: a randomized controlled trial. Pontari MA et al. Multicenter, randomized, double-blind, placebo-controlled trial of pregabalin. 218 men were randomly assigned to treatment for 6 weeks with either 150-600 mg of pregabalin/day or placebo. The primary outcome was a reduction of at least 6 points in the CPSI score. CPSI Responders Placebo N=106 Pregabalin N=218 38(36%) 103(47.2%) So are we getting desperate?

A pollen extract (Cernilton) in patients with inflammatory chronic prostatitis-chronic pelvic pain syndrome: a multicentre, randomised, prospective, double-blind, placebo-controlled phase 3 study. Wagenlehner FM et al. Multicentre, prospective, randomised, double-blind, placebocontrolled trial in men with CP/CPPS (NIH IIIA) Primary end-point, defined as a decrease of the CPSI total score by at least 25% or at least 6 points. CPSI Responders Placebo N=69 Cernilton N=70 50% 71% Take Home Points Poorly understood aetiology/pathogenesis. Heterogenous disease. Established treatments perform poorly in RCT’s.
