Acupuncture for recurrent urinary tract infection in women: a systematic review and meta-analysis

BACKGROUND

Increasing antibiotic resistance has motivated interest in non-antibiotic prophylaxis of recurrent urinary tract infections (rUTI).

OBJECTIVES

To conduct a systematic review of the current state of evidence of acupuncture for uncomplicated rUTI in women.

SEARCH STRATEGY

Nine databases (PubMed, Embase, CENTRAL, CINAHL, AMED, CBM, CNKI, CQVIP, Wanfang) were searched from inception to February 2019.

SELECTION CRITERIA

Randomised controlled trials (RCTs) evaluating the effects of acupuncture and related therapies for prophylaxis or treatment of uncomplicated rUTI in women were included.

DATA COLLECTION AND ANALYSIS

Risk of bias was assessed, and the quality and strength of evidence evaluated using the GRADE framework. Results were reported as risk ratios (RR) for dichotomous outcomes or mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI).

MAIN RESULTS

Five RCTs involving 341 participants were included. Methodological quality of studies and strength of the evidence were low to moderate. The chance of achieving a composite cure with acupuncture therapies was greater than that with antibiotics (three studies, 170 participants, RR 1.92, 95% CI 1.31-2.81, I²  = 38%). The risk of UTI recurrence was lower with acupuncture than with no treatment (two studies, 135 participants, RR 0.39, 95% CI 0.26-0.58, I²  = 0%) and sham acupuncture (one study, 53 participants, RR 0.45, 95% CI 0.22-0.92).

CONCLUSIONS

Acupuncture appeared to be beneficial for treatment and prophylaxis of rUTIs, noting the limitations of the current evidence. Given the growing challenge of antibiotic resistance, there is a need for high-quality RCTs of non-pharmacological interventions such as acupuncture.

TWEETABLE ABSTRACT

This review found that acupuncture may improve treatment and prevent recurrence of urinary tract infection in women.

Recruitment and implementation strategies in randomised controlled trials of acupuncture and herbal medicine in women's health

INTRODUCTION

Recruitment of subjects to clinical trials is known to be difficult and there is little research describing recruitment and implementation strategies to CAM clinical trials. This paper describes the experiences from recruitment and implementation for five randomised controlled trials in women's health conducted in South Australia.

METHODS

Descriptive study reporting on trial documentation and questionnaires completed by women.

RESULTS

Recruitment rates varied between trials and a variety of recruitment strategies were used between studies. Promotion of the trials to the wider community were facilitated by issuing press releases and subsequent reporting by the media. Women found the trial acceptable suggesting factors motivating and preventing women from participating were well addressed.

CONCLUSION

It is hoped that the experiences described here will give some insight to recruitment and implementation strategies. There is a need for more systematic research and evaluation of these strategies, and dissemination of these findings to assist with successful implementation of trials.

Cephalic version by moxibustion for breech presentation

BACKGROUND

Moxibustion (a type of Chinese medicine which involves burning a herb close to the skin) to the acupuncture point Bladder 67 (BL67) (Chinese name Zhiyin), located at the tip of the fifth toe, has been proposed as a way of correcting breech presentation. As caesarean section is often suggested for breech babies due to the potential difficulties during labour, it is preferable to turn the baby before labour starts.

OBJECTIVES

To examine the effectiveness and safety of moxibustion on changing the presentation of an unborn baby in the breech position, the need for external cephalic version (ECV), mode of birth, and perinatal morbidity and mortality for breech presentation.

SEARCH STRATEGY

We searched the Cochrane Pregnancy and Childbirth Group trials register (30 August 2004), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2004), MEDLINE (1966 to March 2004), EMBASE (1980 to March 2004), CINAHL (1982 to March 2004), MIDIRS (1982 to March 2004), CISCOM (9 March 2004) and bibliographies of relevant papers.

SELECTION CRITERIA

The inclusion criteria were published and unpublished randomised controlled trials comparing moxibustion (either alone or in combination with acupuncture) with a control group (no moxibustion), or other methods (e.g. external cephalic version, acupuncture) in women with a singleton breech presentation.

DATA COLLECTION AND ANALYSIS

Both authors assessed eligibility and quality of trials independently. The outcome measures were baby's presentation at birth, need for external cephalic version, mode of birth, perinatal morbidity and mortality, maternal complications and maternal satisfaction, and adverse events.

MAIN RESULTS

Three trials involving a total of 597 women were included. Due to differences in interventions and sample size it was not appropriate to perform a meta-analysis for the main outcome. Only one trial reported on other outcome measures relevant to this review. Moxibustion reduced the need for ECV (relative risk (RR) 0.47, 95% confidence interval (CI) 0.33 to 0.66) and resulted in decreased use of oxytocin before or during labour for women who had vaginal deliveries (RR 0.28, 95% CI 0.13 to 0.60).

AUTHORS' CONCLUSIONS

There is insufficient evidence to support the use of moxibustion to correct a breech presentation. Moxibustion may be beneficial in reducing the need for ECV, and decreasing the use of ocytocin, however there is a need for well-designed randomised controlled trials to evaluate moxibustion for breech presentation which report on clinically relevant outcomes as well as the safety of the intervention.
