Acupuncture in Seasonal Allergic Rhinitis (ACUSAR) - Design and Protocol of a Randomised Controlled Multi-Centre Trial

Background: We report on the study design and protocol of a randomised controlled trial (Acupuncture in Seasonal Allergic Rhinitis, ACUSAR) that investigates the efficacy of acupuncture in the treatment of seasonal allergic rhinitis (SAR). Objective: To investigate whether acupuncture is non-inferior or superior to (a) penetrating sham acupuncture and (b) rescue medication in the treatment of SAR. Design: 3-armed, randomised controlled multi-centre trial with a total follow-up time of 16 weeks in the 1st year and 8 weeks in the 2nd year. Setting: 41 physicians in 37 out-patient units in Germany specialised in acupuncture treatment. Patients: 400 seasonal allergic rhinitis patients with clinical symptoms and test-positive (skin-prick test and/or specific IgE) to both birch and grass pollen. Interventions: Patients will be randomised in a 2:1:1 ratio to one of three groups: (a) semi-standardised acupuncture plus rescue medication (cetirizine); (b) penetrating sham acupuncture at non-acupuncture points plus rescue medication; or (c) rescue medication alone for 8 weeks (standard treatment group). Acupuncture and sham acupuncture will consist of 12 treatments per patient over 8 weeks. Main Outcome Measures: Average means of the Rhinitis Quality of Life Questionnaire (RQLQ) overall score and the Rescue Medication Score (RMS) between weeks 6 and 8 in the first year, adjusted for baseline values. Outlook: The results of this trial available in 2011 will have a major impact on the decision of whether acupuncture should be considered as a therapeutic option in the treatment of SAR

Acupressure in patients with seasonal allergic rhinitis: a randomized controlled exploratory trial

Background: Acupuncture has shown beneficial effects for seasonal allergic rhinitis (SAR); however, it is time and cost intensive. We investigated feasibility and effects of self-administered body acupressure as a self-care technique that stimulates acupuncture points with manual pressure in SAR patients. Methods: We conducted a two-armed randomized controlled exploratory trial to compare effects of self-administered acupressure over 4 weeks at five acupuncture points plus rescue medication (RM) with cetirizine compared to RM alone in SAR patients. Among other outcome parameters, we assessed disease-related quality of life (Rhinitis Quality of Life Questionnaire [RQLQ]), overall SAR symptoms by a visual analogue scale (VAS) and a rescue medication score (RMS) after 4 and 8 weeks. Results: Forty-one SAR patients (mean age 38.5 +/- 10.0 years, n = 21, 51.2% women) were randomized. Compared to RM alone (n = 21), acupressure plus RM (n = 20) was associated with relevant improvements after 4 weeks, shown by the difference between groups in adjusted means of RQLQ: - 0.9 points (95% CI - 1.6 to - 0.2; p = 0.011) and VAS overall SAR symptoms: - 21.6 mm (95% CI - 36.3 to - 6.8; p = 0.005). The RMS was lower in the acupressure group than in the control group: 1.9 points (95% CI - 3.8 to - 0.1; p = 0.120). Group differences decreased slightly until week 8. The acupressure was feasible and safe. Conclusion: Results of this exploratory study indicate that self-applied acupressure is feasible, may improve disease-specific quality of life and reduce disease-related symptoms as well as anti-allergic medication intake in SAR patients. High-quality confirmatory studies including a sham-control group are needed in the future

Traditionelle chinesische Arzneitherapie bei Patienten mit chronischer Rhinosinusitis - eine Therapiebeobachtung mit Berücksichtigung der Arzneimittelherkunft

BACKGROUND The use of Chinese medicinal drugs is becoming more common in Germany. However, the import from China results in aggravated quality controls and potentially jeopardized therapeutic safety. Therefore, in 1999 the Bavarian Department for Agriculture has initiated an interdisciplinary research project to cultivate and analyze important Chinese herbal plants. Currently 16 Bavarian-produced Chinese drugs are in use and distributed to patients by pharmacies. Despite a comparable quality of Bavarian pharmaceutical products, there are concerns remaining as the Bavarian medical drugs have been used for treatment purposes on patients since 2006, without their effect having been compared to the Chinese products. Therefore we performed an observational trial using a parallel group design on patients with chronic rhinosinusitis. METHODS The duration of the trial was 4 weeks. After a 4-week follow-up, the patients were interviewed via telephone. During the trial the patients were given 2 × 50 ml of a decoction of Chinese medicinal herbs, either (a) from Bavarian controlled cultivation (Bavaria group) or (b) from Chinese production (China group). The therapeutic success was evaluated using numerical rating scales. RESULTS In total, 64 patients completed the observational trial (31 Bavaria group, 33 China group). Both groups showed significant improvements in the main symptom scores of chronic rhinosinusitis as well as in secondary symptoms, such as the overall state of health or the tendency to catch a cold. There were no significant differences between the groups concerning the main symptoms scores. Overall the herbal decoctions had no severe side effects. CONCLUSION This observational trial shows that Chinese herbal drugs from Bavarian cultivation are as effective as medicinal herbs imported from China, but the effects of concomitant therapies must be considered as well. The symptom score improvements during the treatment period were obvious and should stimulate further investigation on the efficacy of this herbal formula in the treatment of chronic rhinosinusitis

Traditionelle Chinesische Medizin (TCM) – vom Mythos zur Evidenz

Traditional Chinese medicine (TCM) is the most comprehensive and widely practiced system of medicine in the world.Originally, TCM appeared in our Western context as an unfathomable mythological doctrine. Once the linguistic barriers had been overcome, it became possible to understand and apply the terminological and physiological concepts, the method of diagnosis, and the clinical findings.Since the NIH consensus conference in 1998, our understanding of TCM has been the subject of methodologically robust studies. We now have evidence of the efficacy and effectiveness of acupuncture beyond its use in pain therapy and allergy treatment. Thanks to fMRI studies, among others, we also have a better understanding of the mechanisms underlying acupuncture.Meta-analyses and studies also confirm the efficacy of Chinese medicinal drugs and remedies in some fields, yet there is still extensive need for further research. But opportunities are also emerging for new medicines and prescriptions for (accompanying) treatments of infections, autoimmune diseases, cancer, metabolic illnesses, dermatological disorders, and gastrointestinal diseases.To enable further evaluation of TCM, but also to ensure an integrative, critical application in the practice of TCM, it is vital for doctors to have thorough training. Further institutionalisation is necessary to provide orientation and patient safety.The days of regarding TCM as some kind of mysticism are indeed long over and it can offer real opportunities for better patient care. In many fields, there is increasing evidence of TCM's effectiveness, yet further comprehensive research is essential. This should be encouraged unconditionally

A randomised multicentre trial of acupuncture in patients with seasonal allergic rhinitis – trial intervention including physician and treatment characteristics

Background 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. Methods 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 session Results Acupuncture 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). Conclusions 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

Corrigendum to “The Contribution of Complementary and Alternative Medicine to Reduce Antibiotic Use: A Narrative Review of Health Concepts, Prevention, and Treatment Strategies”

Aim. The aim of this narrative review was to explore the potential contributions of CAM to reduce antibiotic use. Methods. We searched PubMed, Embase, and Cochrane Database of Systematic Reviews with a specific, limited set of search terms and collected input from a group of expert CAM researchers to answer the question: What is known about the contribution of CAM health and health promotion concepts, infection prevention, and infection treatment strategies to reduce antibiotic use? Results. The worldview-related CAM health concepts enable health promotion oriented infection prevention and treatment aimed at strengthening or supporting the self-regulating ability of the human organism to cope with diseases. There is some evidence that the CAM concepts of health (promotion) are in agreement with current conceptualization of health and that doctors who practice both CAM and conventional medicine prescribe less antibiotics, although selection bias of the presented studies cannot be ruled out. There is some evidence that prevention and some treatment strategies are effective and safe. Many CAM treatment strategies are promising but overall lack high quality evidence. Conclusions. CAM prevention and treatment strategies may contribute to reducing antibiotic use, but more rigorous research is necessary to provide high quality evidence of (cost-)effectiveness
