RÉSUMÉ
PURPOSE: We investigated the effect of antibiotics on PSA in asymptomatic patients with mild PSA elevation. MATERIALS AND METHODS: We prospectively evaluated, in a non-randomized design, 106 asymptomatic patients with PSA of 4-10 ng/mL, with a negative digital rectal examination and with no urinary tract infection evidence for 2 years. Patients were divided into two groups: those treated with antibiotics for 3 weeks (G1) and those who were not treated (G2). PSA was taken six weeks after and prostate biopsy was performed in all patients. RESULTS: PCa was diagnosed in 25 of 106 patients (23.6%): 16 (25.0%) in G1 and 9 (21.4%) in G2 (p>0.05). PSA normalization was experienced in 24.5%. In G1, PSA returned to <4 ng/mL in 15 (23.4%) patients compared to 11 (26%) patients in G2. In the patients with a positive biopsy, no significant variation was noted in PSA, fPSA, %fPSA and DPSA after antibiotic treatment. A significantly lower cancer detection rate was noted with decreased PSA, fPSA, and DPSA after antibiotic use. A PSA reduction rate of ≥ 10% occurred in 58.5%, and this was similar in both G1 and G2 groups. The sensibility, specificity and accuracy of PSA reduction of ≥ 10% were 31%, 23% and 25%, respectively. CONCLUSION: Empirical antibiotic therapy in asymptomatic male patients is not related to PSA reduction. The greater than 10% PSA reduction after antibiotic in this population cannot postpone prostate biopsy.

Many great discoveries have been made by chance but some have been the result of human perseverance and ingenuity. A sterling example of the second case is quinquina that was discovered in Peru and is now produced in Java. Quinquina has gone through centuries without losing its medical efficacy that efficacy allowed the exploration and colonization of Africa and played a key role in the ability to conduct overseas military campaigns. Because of its strategic importance, it was a coveted resource. It led to the discovery of homeopathy and dyes, allowed the development of organic chemistry, and has been used to make alcoholic bitters and soft drinks.
