Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The category IIIB CP/CPPS(chronic prostatitis/chronic pelvic pain syndrome) patients with normal leukocyte levels in EPS(expressed prostatic solution, expressed following a digital rectal prostate massage performed by the clinician and collected, once only) were treated with kangLaiTe capsules (KLTc), 1800 mg soft capsule three times a day for 12 weeks. The category IIIA CP/CPPS patients with abnormal leukocyte levels in EPS were treated with KLTc plus antibiotic levofloxacin (KLTc, 1800 mg soft capsule three times a day; levofloxacin oral tablet, 500mg once daily) 12 weeks. To monitor the adherence to the intervention, the tablet returned was recorded.

Treatment: Drugs
Comparator / control treatment
As the control, the category IIIB patients with normal leukocyte levels in EPS were treated with terazosin (oral tablet 2 mg once daily) for 12 weeks; While the category IIIA CP/CPPS patients were treated with terazosin plus levofloxacin (terazosin oral table 2mg once daily; levofloxacin oral tablet 500mg once daily) for 12 weeks. To monitor the adherence to the intervention, the tablet returned was recorded.

Statistical methods / analysis
Descriptive data were presented as numbers (%) while continuous data were presented as mean ± standard deviation. Statistical analysis included two tailed paired/unpaired test to compare domains scores within each group or between both groups. Chi-square test was carried out to compare categorical variables in both groups. Pearson studies applied to define the correlation between differential IIEF-5 score and differential CPSI domains (both presented as percentage). A p < 0.05 was considered to be statistically significant.

Summary
Brief summary
Coix seed oil (KangLaiTe capsules, KLTc) is a kind of neutral oil soft capsule extracted from coix seed, which can significantly improve the body's immunity. We aim to evaluate the efficacy of KLTc monotherapy or combined with antibiotics on patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) by the hypothesis of KLTc treament of CP by adjusting the patient's immune condition. We conducted a prospective, randomized, double-blind, positive-controlled trial with 143 men with CP/CPPS were screened. Finally 60 Patients with category IIIB CP/CPPS were enrolled in monotherapy group, randomly treated with KLTc or terzosin for 12weeks. A total of 60 patients with category IIIA CP/CPPS were enrolled in combined treatment group, treated with KLTc plus levofloxacin, or terzosin plus levofloxacin as positive control. The primary outcome was the changes of NIH-CPSI total score, and the secondary outcomes mainly focused on the immune parameters.

Public notes
KLTc is used in tumor patients for immune improvement. We firstly used KLTc in chronic prostatis just based on its function as immune adjustment. So when we apply for ethics approval, the ethics committee let us try some patients before application. So we finally get the approval on 25/3/2018.
