Impact of acupuncture on antihistamine use in patients suffering seasonal allergic rhinitis: secondary analysis of results from a randomised controlled trial.

ABSTRACT: BACKGROUND:Seasonal allergic rhinitis (SAR) is a common disease that has detrimental effects on the quality of life (QoL) of affected individuals. Approximately 18% of patients try to alleviate their symptoms through acupuncture. The ACUSAR (ACUpuncture in Seasonal Allergic Rhinitis) study (ClinicalTrials.gov registration no. NCT00610584) assessed the impact of acupuncture on SAR, showing significant improvements in rhinitis-specific QoL (RQoL) and in rescue medication (RM) use. OBJECTIVE:A secondary analysis of SAR patients' use of antihistamine. METHODS:Patients were randomised into three study groups: acupuncture plus RM, sham acupuncture plus RM, and RM alone. The patients documented their medication use before and during the intervention period (8?weeks). The main outcome was the number of days with antihistamine use. Statistical analyses were conducted using parametric and non-parametric tests. The robustness of the results was tested by sensitivity analyses using non-parametric bootstrapping. RESULTS:The data from 414 patients were analysed. The acupuncture group used antihistamines significantly less often compared with the other groups (acupuncture vs sham acupuncture: mean difference -4.49 days, p=0.01; acupuncture vs RM: mean difference -9.15 days, p<0.001). Approximately 38% of the acupuncture group did not use any antihistamine in contrast to only 16% in the RM group. The pre-post comparison suggested that the acupuncture patients did not need to increase the days of antihistamine use to alleviate their symptoms, unlike the other groups. CONCLUSIONS:Acupuncture appeared to significantly reduce the number of days of antihistamine use while improving RQoL and SAR symptoms; it can therefore be considered a valuable, additional treatment option for patients with SAR.

Project description:In a large randomised trial in patients with seasonal allergic rhinitis (SAR), acupuncture was superior compared to sham acupuncture and rescue medication. The aim of this paper is to describe the characteristics of the trial's participating physicians and to describe the trial intervention in accordance with the STRICTA (Standards for Reporting Interventions in Controlled Trials of Acupuncture) guidelines, to make details of the trial intervention more transparent to researchers and physicians.ACUSAR (ACUpuncture in Seasonal Allergic Rhinitis) was a three-armed, randomised, controlled multicentre trial. 422 SAR patients were randomised to semi-standardised acupuncture plus rescue medication (RM, cetirizine), sham acupuncture plus RM or RM alone. We sent a questionnaire to trial physicians in order to evaluate their characteristics regarding their education about and experience in providing acupuncture. During the trial, acupuncturists were asked to diagnose all of their patients according to Chinese Medicine (CM) as a basis for the semi-standardised, individualized intervention in the acupuncture group. Every acupuncture point used in this trial had to be documented after each sessionAcupuncture was administered in outpatient clinics by 46 (mean age 47?±?10 years; 24 female/ 22 male) conventionally-trained medical doctors (67% with postgraduate specialization such as internal or family medicine) with additional extensive acupuncture training (median 500 hours (1st quartile 350, 3rd quartile 1000 hours with 73% presenting a B-diploma in acupuncture training (350 hours)) and experience (mean 14 years in practice). The most reported traditional CM diagnosis was 'wind-cold invading the lung' (37%) and 'wind-heat invading the lung' (37%), followed by 'lung and spleen qi deficiency' (9%). The total number of needles used was higher in the acupuncture group compared to the sham acupuncture group (15.7 ± 2.5 vs. 10.0 ± 1.6).The trial interventions were provided by well educated and experienced acupuncturists. The different number of needles in both intervention groups could be possibly a reason for the better clinical effect in SAR patients. For future trials it might be more appropriate to ensure that acupuncture and sham acupuncture groups should each be treated by a similar number of needles.ClinicalTrials.gov: NCT00610584.
