Abstract:
AIMTo assess the efficacy and safety of anal submucosal injection (ASI) of amikacin in chronic bacterial prostatitis (CBP).
METHODSFifty male outpatients with CBP were randomly divided into two groups. Thirty cases of ASI group were given amikacin 400 mg daily by ASI for ten times and the other twenty cases of intramuscular injection (IM) group were given the same drug daily by IM. All patients were evaluated with NIH-Chronic prostatitis symptom index (NIH-CPSI), the bacteria culture of the expressed prostate secretion (EPS), proctoscopic examination, rectal biopsy and the clinical manifestation were checked at pretreatment and on day 7 and 90 after cessation of therapy.
RESULTSThe cure rate, apparent effective rate and effective rate of ASI group and IM group were 33.3% vs 5% (P<0.05), 43.3% vs 10% (P<0.05) and 16.7% vs 20% (P>0.05), respectively. The score of NIH-CPSI in both of ASI group and IM group decreased significantly 7 days after cessation of therapy, both ASI and IM of amikacin could relieve symptoms within a short time. However, 3 months after cessation of therapy the score of NIH-CPSI in ASI group continued down in spite of no significant differences compared with 7 days after cessation of therapy, but the score of IM group was rebound nearly closed to level of pretreatment at 23.8 8.5 and significantly higher than that of ASI group. The amount of white blood cell (WBC) of EPS in ASI group increased slightly at 7 days after cessation of therapy without significant difference with pretreatment (P>0.05), but it significantly decreased at 3 months after cessation of therapy, the amount of WBC of EPS in ASI group was lower than that of IM group at 3 months after cessation of therapy (P<0.05). Proctoscopic examination of anal canal were normal after ASI therapy and the rectum biopsy showed no obvious histopathologic abnormality at the site of injection except mild focal submucosal infiltration of lymphocytes and plasma cells at 7 days after cessation of therapy which disappeared on 3 months after cessation of therapy. All patients had no evident complications.
CONCLUSIONASI could be recommended as a new safe, effective, painless method of antibiotics administration in the treatment of CBP.
