UNLABELLED Chinese translation BACKGROUND Acupuncture is frequently used to treat seasonal allergic rhinitis (SAR) despite limited scientific evidence. OBJECTIVE To evaluate the effects of acupuncture in patients with SAR. DESIGN Randomized, controlled multicenter trial. (ClinicalTrials.gov: NCT00610584) SETTING 46 specialized physicians in 6 hospital clinics and 32 private outpatient clinics. PATIENTS 422 persons with SAR and IgE sensitization to birch and grass pollen. INTERVENTION Acupuncture plus rescue medication (RM) (cetirizine) (n = 212), sham acupuncture plus RM (n = 102), or RM alone (n = 108). Twelve treatments were provided over 8 weeks in the first year. MEASUREMENTS Changes in the Rhinitis Quality of Life Questionnaire (RQLQ) overall score and the RM score (RMS) from baseline to weeks 7 and 8 and week 16 in the first year and week 8 in the second year after randomization, with predefined noninferiority margins of -0.5 point (RQLQ) and -1.5 points (RMS). RESULTS Compared with sham acupuncture and with RM, acupuncture was associated with improvement in RQLQ score (sham vs. acupuncture mean difference, 0.5 point [97.5% CI, 0.2 to 0.8 point; P < 0.001]; RM vs. acupuncture mean difference, 0.7 point [97.5% CI, 0.4 to 1.0 point; P < 0.001]) and RMS (sham vs. acupuncture mean difference, 1.1 points [97.5% CI, 0.4 to 1.9 points; P < 0.001]; RM vs. acupuncture mean difference, 1.5 points [97.5% CI, 0.8 to 2.2 points; P < 0.001]). There were no differences after 16 weeks in the first year. After the 8-week follow-up phase in the second year, small improvements favoring real acupuncture over the sham procedure were noted (RQLQ mean difference, 0.3 point [95% CI, 0.03 to 0.6 point; P = 0.032]; RMS mean difference, 1.0 point [95% CI, 0.2 to 1.9 points; P = 0.018]). LIMITATION The study was not powered to detect rare adverse events, and the RQLQ and RMS values were low at baseline. CONCLUSION Acupuncture led to statistically significant improvements in disease-specific quality of life and antihistamine use measures after 8 weeks of treatment compared with sham acupuncture and with RM alone, but the improvements may not be clinically significant.

IntroductionCupping is used in various traditional medicine forms to relieve pain in musculoskeletal diseases. The aim of this study was to investigate the effectiveness of cupping in relieving the symptoms of knee osteoarthritis (OA).MethodsIn a two-group, randomized controlled exploratory pilot study patients with a clinically and radiological confirmed knee OA (Kellgren-Lawrence Grading Scale: 2-4) and a pain intensity > 40 mm on a 100 mm visual analogue scale (VAS) were included. 40 Patients were randomized to either 8 sessions of pulsatile dry cupping within 4 weeks or no intervention (control). Paracetamol was allowed on demand for both groups. Outcomes were the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) score, the pain intensity on a VAS (0 mm = no pain to 100 mm = maximum intensity) and Quality of Life (SF-36) 4 and 12 weeks after randomization. Use of Paracetamol was documented within the 4-week treatment period. Analyses were performed by analysis of covariance adjusting for the baseline value for each outcome.Results21 patients were allocated to the cupping group (5 male; mean age 68 ± SD 7.2) and 19 to the control group (8 male; 69 ± 6.8). After 4 weeks the WOMAC global score improved significantly more in the cupping group with a mean of 27.7 (95% confidence interval 22.1; 33.3) compared to 42.2 (36.3; 48.1) in the control group (p = 0.001). After 12 weeks the WOMAC global score were still significantly different in favor for cupping (31.0 (24.9; 37.2) vs. 40.8 (34.4; 47.3) p = 0.032), however the WOMAC subscores for pain and stiffness were not significant anymore. Significantly better outcomes in the cupping group were also observed for pain intensity on VAS and for the SF-36 Physical Component Scale compared to the control group after 4 and 12 weeks. No significant difference was observed for the SF-36 Mental Component Scale and the total number of consumed Paracetamol tablets between both groups (mean 9.1, SD ± 20.0 vs. 11.5 ± 15.9).ConclusionIn this exploratory study dry cupping with a pulsatile cupping device relieved symptoms of knee OA compared to no intervention. Further studies comparing cupping with active treatments are needed.Trial registrationClinicaltrials.gov Identifier: NCT01057043

BACKGROUND Allergic rhinitis (AR) is a frequent allergic disorder with a significant economic effect on health care costs and productivity. OBJECTIVE To assess the cost-effectiveness of acupuncture for patients with seasonal AR (SAR) in Germany. METHODS The present analysis was part of the Acupuncture in Seasonal Allergic Rhinitis (ACUSAR) trial, a 3-arm randomized, controlled, multicenter trial in patients with SAR, comparing acupuncture plus rescue medication (RM), penetrating sham acupuncture plus RM, and a control group receiving RM alone. Measures for health economic analyses were costs and health-related quality of life. Incremental cost-effectiveness ratio was calculated for different scenarios on the duration of acupuncture effects and was expressed as costs per quality-adjusted life-year gained. The study was conducted from societys and from a third-party payers perspective. RESULTS From 422 initially randomized patients, a total of 364 patients with complete data on costs and quality of life were included in the health economic evaluation. Patients receiving acupuncture or sham acupuncture caused higher costs than patients in the RM group. Patients in the acupuncture group gained significantly more quality-adjusted life-years compared with the RM group. Depending on different scenarios, the incremental cost-effectiveness ratio for acupuncture patients was between €31,241 (approximately US

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.

PURPOSE Despite known cholesterol lowering effects the use of psyllium husk (Plantaginis ovatae testa) in Germany for hypercholesterolemia is limited compared to their use as a laxative. To investigate whether use in hypercholesterolemia is limited due to adverse effects on the gastrointestinal system, a prospective observational study was conducted. METHODS Sixty-two outpatients with documented hypercholesterolemia and complaints of constipation were identified from an academic clinical center. Treatment with 3.5g psyllium husk preparation administered three times daily was initiated and patients were monitored at weekly intervals. Gastrointestinal symptoms were quantified using a validated Nepean Dyspepsia Index modified to identify both upper and lower abdominal symptoms. Diaries and study medication records were used to evaluate compliance. RESULTS Fifty-four of 62 patients enrolled in the study completed the study protocol with 4 subjects discontinuing due to adverse reactions associated with psyllium husks. Total cholesterol was significantly decreased from 252+/-39mg/dl before treatment to 239+/-37mg/dl after 3 weeks of treatment. Similarly, low density lipoprotein (LDL)-cholesterol decreased from 174+/-34 to 162+/-31mg/dl during the study. Triglycerides and high density lipoprotein (HDL) were unchanged. Gastrointestinal symptoms were rated lower at the end than at the beginning of the study. In week 1 most of the patients reported gastrointestinal symptoms and also gastrointestinal adverse reactions, which however, showed a decrease from week 1 to weeks 2 and 3 in the diaries. Patient response to study medication was positive for patients completing the study. CONCLUSIONS Psyllium husk preparations may be a therapeutic option for patients with mild to moderately elevated cholesterol levels. Adverse gastrointestinal symptoms associated with the preparation appear to be transient in some of the patients. Compliance may be optimized with adequate patient counseling.

Background. The aim of this randomized, controlled study was to investigate the effectiveness of a mindful walking program in patients with high levels of perceived psychological distress. Methods. Participants aged between 18 and 65 years with moderate to high levels of perceived psychological distress were randomized to 8 sessions of mindful walking in 4 weeks (each 40 minutes walking, 10 minutes mindful walking, 10 minutes discussion) or to no study intervention (waiting group). Primary outcome parameter was the difference to baseline on Cohens Perceived Stress Scale (CPSS) after 4 weeks between intervention and control. Results. Seventy-four participants were randomized in the study; 36 (32 female, 52.3 ± 8.6 years) were allocated to the intervention and 38 (35 female, 49.5 ± 8.8 years) to the control group. Adjusted CPSS differences after 4 weeks were −8.8 [95% CI: −10.8; −6.8] (mean 24.2 [22.2; 26.2]) in the intervention group and −1.0 [−2.9; 0.9] (mean 32.0 [30.1; 33.9]) in the control group, resulting in a highly significant group difference (P < 0.001). Conclusion. Patients participating in a mindful walking program showed reduced psychological stress symptoms and improved quality of life compared to no study intervention. Further studies should include an active treatment group and a long-term follow-up.
