(HealthDay News) — For men with moderate-to-severe chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), 20 sessions of acupuncture results in greater improvement of symptoms than sham acupuncture, according to a study published online in the Annals of Internal Medicine.
Yuanjie Sun, MD, from Guang’anmen Hospital at the China Academy of Chinese Medical Sciences in Beijing, and colleagues examined the long-term efficacy of acupuncture for CP/CPPS in a multicenter, randomized, sham-controlled trial conducted at 10 tertiary hospitals in China. A total of 440 men with moderate-to-severe CP/CPPS were randomly assigned to 20 sessions of either acupuncture or sham acupuncture over 8 weeks, and followed up for 24 weeks.
The researchers found that the proportion of responders was 60.6 and 36.8% at week 8 in the acupuncture and sham acupuncture groups, respectively (adjusted odds ratio, 2.6). The corresponding proportions were 61.5 and 38.3%, respectively, at 32 weeks (adjusted odds ratio, 2.6). There were 20 and 14 adverse events (9.1 and 6.4%) reported in the acupuncture and sham acupuncture groups, respectively, but no reports of serious adverse events.
“Eight weeks of acupuncture may result in clinically important improvements in symptoms of moderate-to-severe CP/CPPS, with durable efficacy for at least 24 weeks after treatment,” the authors write. “This trial showed long-term efficacy of acupuncture and provides high-quality evidence for clinical practice and guideline recommendations.”
