Traditional chinese medicine for the treatment of chronic prostatitis in China: a systematic review and meta-analysis.

Abstract

OBJECTIVE:

To systematically evaluate the effectiveness of Chinese herbal medicine for treating chronic prostatitis (CPT) in China.

DESIGN:

Electronic medical database from China National Knowledge Infrastructure (CNKI) was searched, language is Chinese; date is from January 1, 1994 to December 31, 2003. A total of 108 trials were found, and all studies with words like "randomization" or "quasi-randomization" in their abstracts were included, whether they used blinding or not. Nineteen theses that met the entry criteria were downloaded and fully printed. Four groups were divided: Chinese herbs orally treated group (based on syndrome differentiation), Chinese herbs externally treated group, Chinese herbs orally and externally treated group, and integrated Western with Chinese herbs treated group.

RESULTS:

All 19 articles that met the entry criteria were clinical trial studies with low quality (Jadad Score <3). The results showed that Traditional Chinese Medicine (TCM) may benefit the patients who had CPT. However, from the results of the funnel plots analysis of all four groups of clinical trials that met the inclusion criteria in this systematic review are distant asymmetrical and irregular plots, which indicate that a positive publication bias may exist. There was no obvious evidence indicating that the efficacy of the therapy in the treated groups using TCM was superior to that of the control group (Western medicine treatment group).

CONCLUSIONS:

All of the four groups in the clinical trials have not provided evidence of evidence-based medicine (EBM) A class (including 1a, 1b, 1c level), failed to prove that the TCM may have beneficial effects for patients with CPT, because of low quality in all the trials and a positive publication bias. Therefore, in light of some positive outcomes, a good design of multicentered, randomized, parallel-controlled and blinding trials is needed in order to make further studies, and deserve further examination for the treatment of CPT with TCM.
