[A possible therapeutic improvement of the antibacterial effect by monitoring the production of leukocyte free oxygen radicals during antibiotic treatment of infertile patients with chronic bacterial prostatitis].

Abstract

In the male chronic accessory gland bacterial infections (AGBI), antibiotic treatment (AT) efficacy usually evaluates the antimicrobial outcome through one or more spermiocolture (SC) become negative. Recently, bacterial olipeptide fMPL has been used to detect a specific Radical Oxygen Species production by leukocytes (L-RLO), even when they are present at low concentrations in sperm fractions specimens. In the male AGBI could be present endogenous fMLP at sufficient levels to produce L chemiotaxis in the semen, and secondly active their specific L-RLO production, till when bacteriospermia remained positive. In the Percoll 50% (Pc50%) fraction, at higher L concentrations, from 22 infertile patients affected by chronic bacterial prostatitis (BP) and enrolled to a randomly AT treatment with a Quinolone (n = 12) or a Macrolide (n = 10), through two secondary milestones (possible elevated basal L-RLO in the pre-treatment, T0; significant changes in the basal and fMLP-stimulated L-RLO production within each treatment group and between groups), we would verify if a normalized L-RLO production could be taken as break-point for the AT withdrawal before checking SC for control. Indeed, in T0 all patients had positive SC and exhibited both basal and fMLP-stimulated L-RLO levels higher than those observed in 2 control groups (group cA = 10 fertile men, without chronic BP; group cB = 10 patients affected by chronic abacterial prostatitis (AP). On the 3rd AT cycle for 14 days, together in 20/22 AT-treated patients, basal and fMLP-stimulated L-RLO levels become low or normal, as well as their SCs become negative (CFU/ml = 0), whilst in a third control group (group cC) of 10 not-AT-treated BP patients, through matched-follow-up observations, these L-RLO values were always elevated and their SC remained positive (CFU/ml > or = 10(5)). In chronic BP patients, AT seems to demonstrate both antimicrobial effectiveness and reduction of L-RLO production with values similar to those of control group cA. The monitored L-RLO values during AT could be useful in order to ottimize antimicrobial effect: this tool being able to previse SC outcome, could be assumed to define clearly AT break-point and/or cycle numbers.
