Homeopathic treatment of elderly patients--a prospective observational study with follow-up over a two year period.

BACKGROUND: Very little is known about the range of diagnoses, course of treatment and long-term outcome in elderly patients who choose to receive homeopathic medical treatment. We investigated homeopathic practice in an industrialised country under everyday conditions.The aim of the study was to determine the spectrum of diagnoses and treatments, as well as to describe the course of illness over time among older patients who chose to receive homeopathic treatment. METHODS: In this subgroup analysis of a prospective, multicentre cohort study totally including 3981 patients treated by homeopathic physicians in primary care practices in Germany and Switzerland, data was analysed from all patients > 70 years consulting the physician for the first time. The main outcome measures were: assessment by patient of the severity of complaints (numeric rating scales) and quality of life (SF-36) and by the physician of the severity of diagnoses (numeric rating scales) at baseline, and after 3, 12, and 24 months. RESULTS: A total of 83 patients were included in the subgroup analysis (41% men, mean age 73.2 +/- (SD) 3.1 years; 59% women, 74.3 +/- 3.8 years).98.6 percent of all diagnoses were chronic with an average duration of 11.5 +/- 11.5 years. 82 percent of the patients were taking medication at baseline.The most frequent diagnoses were hypertension (20.5%, 11.1 +/- 7.5 years) and sleep disturbances (15.7%, 22.1 +/- 25.8 years).The severity of complaints decreased significantly between baseline and 24 months in both patients (from 6.3 (95%CI: 5.7-6.8) to 4.6 (4.0-5.1), p < 0.001) and physicians' assessments (from 6.6 (6.0-7.1) to 3.7 (3.2-4.3), p < 0.001); quality of life (SF 36) and the number of medicines taken did not significantly change. CONCLUSION: The severity of disease showed marked and sustained improvements under homeopathic treatment, but this did not lead to an improvement of quality of life. Our findings might indicate that homeopathic medical therapy may play a beneficial role in the long-term care of older adults with chronic diseases and studies on comparative effectiveness are needed to evaluate this hypothesis.

Homoeopathic versus conventional therapy for atopic eczema in children: medical and economic results.

BACKGROUND: One of five children visiting a homoeopathic physician is suffering from atopic eczema. OBJECTIVE: To examine the effectiveness, safety and costs of homoeopathic versus conventional treatment in usual care. METHODS: In a prospective multicentre comparative observational non-randomised study, 135 children (homoeopathy n = 48 vs. conventional n = 87) with mild to moderate atopic eczema were included. The primary outcome was the SCORAD (Scoring Atopic Dermatitis) at 6 months. Further outcomes at 6 and 12 months also included quality of life of parents and children, use of conventional medicine, treatment safety and disease-related costs. RESULTS: The adjusted SCORAD showed no significant differences between the groups at both 6 months (homoeopathy 22.49 + or - 3.02 [mean + or - SE] vs. conventional 18.20 + or - 2.31, p = 0.290) and 12 months (17.41 + or - 3.01 vs. 17.29 + or - 2.31, p = 0.974). Adjusted costs were higher in the homoeopathic than in the conventional group: for the first 6 months EUR 935.02 vs. EUR 514.44, p = 0.026, and for 12 months EUR 1,524.23 vs. EUR 721.21, p = 0.001. Quality of life was not significantly different between both groups. CONCLUSION: Taking patient preferences into account, homoeopathic treatment was not superior to conventional treatment for children with mild to moderate atopic eczema.

Homeopathic treatment of patients with dysmenorrhea: a prospective observational study with 2 years follow-up.

PURPOSE: Evaluating homeopathic treatment for dysmenorrhea. METHODS: Prospective multicenter observational study in primary care, using standardized questionnaires to record for 2 years diseases, quality of life, medical history, consultations, all treatments, other health services use. RESULTS: Fifty-seven physicians treated 128 women (age 32.4 +/- 7.5 years, mean +/- SD) and 11 girls (13.7 +/- 4.0). Women had dysmenorrhea for 11.6 +/- 9.0 (girls 3.1 +/- 1.5) years. Patients received 7.5 +/- 6.5 (5.9 +/- 3.7) homeopathic prescriptions. Diagnoses and complaints severity improved markedly [at 24 months, dysmenorrhea relieved by > 50% of baseline rating in 46.1% (59) of the women and 45.5% (5) of the girls] with large effect sizes (24 months: Cohen's d from 1.18 to 2.93). In addition, QoL improved (24 months: SF-36 physical component score: 0.25, mental component score 0.25, KINDL sum score 0.27). Conventional medication changed little and use of other health services decreased. CONCLUSIONS: Patients with dysmenorrhea improved under homeopathic treatment. Controlled studies should investigate efficacy and effectiveness.

Homeopathic treatment of patients with chronic sinusitis: A prospective observational study with 8 years follow-up.

BACKGROUND: An evaluation of homeopathic treatment and the outcomes in patients suffering from sinusitis for >or=12 weeks in a usual care situation. METHODS: Subgroup analysis including all patients with chronic sinusitis (ICD-9: 473.9; >or=12 weeks duration) of a large prospective multicentre observational study population. Consecutive patients presenting for homeopathic treatment were followed-up for 2 years, and complaint severity, health-related quality of life (QoL), and medication use were regularly recorded. We also present here patient-reported health status 8 years post initial treatment. RESULTS: The study included 134 adults (mean age 39.8 +/- 10.4 years, 76.1% women), treated by 62 physicians. Patients had suffered from chronic sinusitis for 10.7 +/- 9.8 years. Almost all patients (97.0%) had previously been treated with conventional medicine. For sinusitis, effect size (effect divided by standard deviation at baseline) of complaint severity was 1.58 (95% CI 1.77; 1.40), 2.15 (2.38; 1.92), and 2.43 (2.68; 2.18) at 3, 12, and 24 months respectively. QoL improved accordingly, with SF-36 changes in physical component score 0.27 (0.15; 0.39), 0.35 (0.19; 0.52), 0.44 (0.23; 0.65) and mental component score 0.66 (0.49; 0.84), 0.71 (0.50; 0.92), 0.65 (0.39; 0.92), 0.74 (0.49; 1.00) at these points. The effects were still present after 8 years with SF-36 physical component score 0.38 (0.10; 0.65) and mental component score 0.74 (0.49; 1.00). CONCLUSION: This observational study showed relevant improvements that persisted for 8 years in patients seeking homeopathic treatment because of sinusitis. The extent to which the observed effects are due to the life-style regulation and placebo or context effects associated with the treatment needs clarification in future explanatory studies.

How healthy are chronically ill patients after eight years of homeopathic treatment?--Results from a long term observational study.

BACKGROUND: Homeopathy is a highly debated but often used medical treatment. With this cohort study we aimed to evaluate health status changes under homeopathic treatment in routine care. Here we extend former results, now presenting data of an 8-year follow-up. METHODS: In a prospective, multicentre cohort study with 103 homeopathic primary care practices in Germany and Switzerland, data from all patients (age >1 year) consulting the physician for the first time were observed. The main outcome measures were: The patients' perceived change in complaint severity (numeric rating scales from 0 = no complaint to 10 = maximal severity) and quality of life as measured by the SF-36 at baseline, and after 2 and 8 years. RESULTS: A total of 3,709 patients were studied, 73% (2,722 adults, 72.8% female, age at baseline 41.0 +/- 12.3; 819 children, 48.4% female, age 6.5 +/- 4.0) contributed data to the 8-year follow-up. The most frequent diagnoses were allergic rhinitis and headache in adults, and atopic dermatitis and multiple recurrent infections in children. Disease severity decreased significantly (p < 0.001) between baseline, 2 and 8 years (adults from 6.2 +/- 1.7 to 2.9 +/- 2.2 and 2.7 +/- 2.1; children from 6.1 +/- 1.8 to 2.1 +/- 2.0 and 1.7 +/- 1.9). Physical and mental quality of life sores also increased considerably. Younger age, female gender and more severe disease at baseline were factors predictive of better therapeutic success. CONCLUSION: Patients who seek homeopathic treatment are likely to improve considerably. These effects persist for as long as 8 years.

The in vitro evidence for an effect of high homeopathic potencies--a systematic review of the literature.

OBJECTIVE: Systematic assessment of the in vitro research on high potency effects. METHOD: Publications of experiments were collected through databases, experts, previous reviews, citation tracking. INCLUSION CRITERIA: stepwise agitated dilutions <10(-23); cells or molecules from human or animal. Experiments were assessed with the modified SAPEH score. RESULTS: From 75 publications, 67 experiments (1/3 of them replications) were evaluated. Nearly 3/4 of them found a high potency effect, and 2/3 of those 18 that scored 6 points or more and controlled contamination. Nearly 3/4 of all replications were positive. Design and experimental models of the reviewed experiments were inhomogenous, most were performed on basophiles. CONCLUSIONS: Even experiments with a high methodological standard could demonstrate an effect of high potencies. No positive result was stable enough to be reproduced by all investigators. A general adoption of succussed controls, randomization and blinding would strengthen the evidence of future experiments.

Use of complementary and alternative medicine in Germany - a survey of patients with inflammatory bowel disease.

BACKGROUND: Previous studies have suggested an increasing use of complementary and alternative medicine (CAM) in patients with inflammatory bowel disease (IBD). The aim of our study was to evaluate the use of CAM in German patients with IBD. METHODS: A questionnaire was offered to IBD patients participating in patient workshops which were organized by a self-help association, the German Crohn's and Colitis Association. The self-administered questionnaire included demographic and disease-related data as well as items analysing the extent of CAM use and satisfaction with CAM treatment. Seven commonly used CAM methods were predetermined on the questionnaire. RESULTS: 413 questionnaires were completed and included in the analysis (n = 153 male, n = 260 female; n = 246 Crohn's disease, n = 164 ulcerative colitis). 52 % of the patients reported CAM use in the present or past. In detail, homeopathy (55%), probiotics (43%), classical naturopathy (38%), Boswellia serrata extracts (36%) and acupuncture/Traditional Chinese Medicine (TCM) (33%) were the most frequently used CAM methods. Patients using probiotics, acupuncture and Boswellia serrata extracts (incense) reported more positive therapeutic effects than others. Within the statistical analysis no significant predictors for CAM use were found. 77% of the patients felt insufficiently informed about CAM. CONCLUSION: The use of CAM in IBD patients is very common in Germany, although a large proportion of patients felt that information about CAM is not sufficient. However, to provide an evidence-based approach more research in this field is desperately needed. Therefore, physicians should increasingly inform IBD patients about benefits and limitations of CAM treatment.

Does potentized HgCl2 (Mercurius corrosivus) affect the activity of diastase and alpha-amylase?

BACKGROUND: Homeopathic drugs even with dilutions beyond 10(23) (high potencies) are frequently used, although their working mechanism is still unknown. Curative information preserved in solvent structure is postulated to exert biologic effects. OBJECTIVE: The objective was to test for a stimulating or inhibiting effect of high potencies of the homeopathic remedy HgCl2 (Mercurius corrosivus) on two sugar hydrolases. METHODS: High potencies were produced using stepwise dilution plus shaking. Controls included potentized solvent (aqua bidestillata), equimolar dilutions without shaking, and enzyme-free references. Tested were potencies with dilution factors 1:200 (CC) on diastase extract from winter barley, and 1:100 (C) on alpha-amylase from hog pancreas. Enzyme activity was colorimetrically determined by Lugol's iodine-starch reaction. RESULTS: An inhibiting effect of HgCl2 on enzyme activities was observed only in low potencies and dilutions. Statistically significant differences between potencies and controls were not found in randomized and blinded experiments. CONCLUSIONS: This experimental design provided independent reproducible results of cell-free in vitro assays. However, it did not indicate an effect of potentized HgCl2 on hydrolases. Demonstrating potency effects may require additional experimental features.

Homeopathic medical practice: long-term results of a cohort study with 3981 patients.

BACKGROUND: On the range of diagnoses, course of treatment, and long-term outcome in patients who chose to receive homeopathic medical treatment very little is known. We investigated homeopathic practice in an industrialized country under everyday conditions. METHODS: In a prospective, multicentre cohort study with 103 primary care practices with additional specialisation in homeopathy in Germany and Switzerland, data from all patients (age > 1 year) consulting the physician for the first time were observed. The main outcome measures were: Patient and physician assessments (numeric rating scales from 0 to 10) and quality of life at baseline, and after 3, 12, and 24 months. RESULTS: A total of 3,981 patients were studied including 2,851 adults (29% men, mean age 42.5 +/- 13.1 years; 71% women, 39.9 +/- 12.4 years) and 1,130 children (52% boys, 6.5 +/- 3.9 years; 48% girls, 7.0 +/- 4.3 years). Ninety-seven percent of all diagnoses were chronic with an average duration of 8.8 +/- 8 years. The most frequent diagnoses were allergic rhinitis in men, headache in women, and atopic dermatitis in children. Disease severity decreased significantly (p < 0.001) between baseline and 24 months (adults from 6.2 +/- 1.7 to 3.0 +/- 2.2; children from 6.1 +/- 1.8 to 2.2 +/- 1.9). Physicians' assessments yielded similar results. For adults and young children, major improvements were observed for quality of life, whereas no changes were seen in adolescents. Younger age and more severe disease at baseline were factors predictive of better therapeutic success. CONCLUSION: Disease severity and quality of life demonstrated marked and sustained improvements following homeopathic treatment period. Our findings indicate that homeopathic medical therapy may play a beneficial role in the long-term care of patients with chronic diseases.

Outcome and costs of homoeopathic and conventional treatment strategies: a comparative cohort study in patients with chronic disorders.

OBJECTIVES: To evaluate the effectiveness of homoeopathy versus conventional treatment in routine care. DESIGN: Comparative cohort study. SETTING: Patients with selected chronic diagnoses were enrolled in medical practice. INTERVENTIONS: Conventional treatment or homeopathy. OUTCOME MEASURES: Severity of symptoms assessed by patients and physicians (visual rating scale, 0-10) at baseline, 6 and 12 months and costs. RESULTS: The analyses of 493 patients (315 adults, 178 children) indicated greater improvement in patients' assessments after homoeopathic versus conventional treatment (adults: homeopathy from 5.7 to 3.2; conventional, 5.9-4.4; p=0.002; children from 5.1 to 2.6 and from 4.5 to 3.2). Physician assessments were also more favourable for children who had received homoeopathic treatment (4.6-2.0 and 3.9-2.7; p<0.001). Overall costs showed no significant differences between both treatment groups (adults, 2155 versus 2013, p=0.856; children, 1471 versus 786, p=0.137). CONCLUSION: Patients seeking homoeopathic treatment had a better outcome overall compared with patients on conventional treatment, whereas total costs in both groups were similar.

High homeopathic potencies are different from potentized solvent when investigated with the REDEM technology.

OBJECTIVE: To determine in a series of randomized blinded experiments using the REDEM technology whether differences between high homeopathic potencies and similarly potentized solvent can be detected. DESIGN AND ANALYSIS: A REDEM device was employed as a black box. Samples were measured in a capacitor that was connected to 60 individual oscillator circuits at frequencies between 250 and 930 KHz; their oscillation damping was recorded. In two experiments (3 and 4 replications) stable differences between a potentized 'mother tincture' and potentized solvent were assessed. Statistical analysis was done using ANCOVA. RESULTS: Significant differences (p < 0.01) between remedy and control were found, mostly at the same oscillator frequencies. Those differences found for only one remedy always were at frequencies adjacent to frequencies with differences for other remedies. VISUAL ANALYSIS: Where output curves were not near 0, remedy values were higher than controls. Curves within a replication ran parallel, their distances varied. Between replications, curve shapes and remedy- control differences were similar, however, control curves varied in height. Control and remedy curves between experiments varied in shape. Effects increased with time and sample conductivity. Ethanol 43% as solvent eliminated the observed effects, use of polyethylene containers considerably attenuated them. CONCLUSIONS: A probably physical difference was seen between potentized homeopathic remedies and potentized solvent. The differences are associated with sample age, solvent, and container material. The REDEM technology requires further investigation to determine the nature of the underlying mechanisms of the observed differences.

[Opportunities of conventional evaluation in complementary and alternative medicine]. / Möglichkeiten konventioneller Evaluation in der Komplementärmedizin.

Patients frequently require and utilise complementary and alternative medicine in spite of the present lack of evidence of effectiveness for many methods. However, convincing research based on conventional study types (cross-sectional studies, observational studies, comparative studies, randomised controlled trials, and meta-analyses) allows a scientifically sound assessment, e.g. for homeopathy, acupuncture, and anthroposophic medicine. The established study methodology is, therefore, applicable to complementary and alternative medicine; the available results should be the basis for recommendation of effective clinical strategies as well as for health policy decisions.

Quality assessment of physical research in homeopathy.

OBJECTIVES: To assess the evidence of published experiments on homeopathic preparations (potencies) that target physical properties (i.e., assumed structural changes in solvents). METHOD: A suitable instrument (the Score for Assessment of Physical Experiments on Homeopathy [SAPEH]) was developed through consensus procedure: a scale with 8 items covering 10 criteria, based on the 3 constructs, methodology, presentation, and experiment standardization. REVIEWED PUBLICATIONS: Written reports providing at least minimal details on physical experiments with methods to identify structural changes in solvents were collected. These reports were scored when they concerned agitated preparations in a dilution less than 10(-23), with no other restrictions. We found 44 publications that included 36 experiments (the identity of 2 was unclear). They were classified into 6 types (dielectric strength, 6; galvanic effects, 5; light absorption, 4; nuclear magnetic resonance [NMR], 18; Raman spectroscopy, 7; black boxes of undisclosed design, 4). RESULTS: Most publications were of low quality (SAPEH < 6), only 6 were of high quality (SAPEH > 7, including 2 points for adequate controls). These report 3 experiments (1 NMR, 2 black boxes), of which 2 claim specific features for homeopathic remedies, as does the only medium-quality experiment with sufficient controls. CONCLUSIONS: Most physical experiments of homeopathic preparations were performed with inadequate controls or had other serious flaws that prevented any meaningful conclusion. Except for those of high quality, all experiments should be repeated using stricter methodology and standardization before they are accepted as indications of special features of homeopathic potencies.

How objective are systematic reviews? Differences between reviews on complementary medicine.

Systematic reviews are considered the most reliable tool to summarize existing evidence. To determine whether reviews that address the same questions can produce different answers we examined systematic reviews of herbal medicine, homeopathy, and acupuncture taken from a previously established database. Information on literature searching, inclusion criteria, selection process, quality assessment, data extraction, methods to summarize primary studies, number of included studies, results and conclusions was compared qualitatively. Seventeen topics (eight on acupuncture, six on herbal medicines, three on homeopathy) had been addressed by 2-5 systematic reviews each. The number of primary studies in the reviews varied greatly within most topics. The most obvious reason for discrepancies between the samples was different inclusion criteria (in thirteen topics). Methods of literature searching may have contributed with some topics but the equivalence of the searches was difficult to assess. Differences were frequently observed in other methodological aspects, in results and in conclusions. This analysis shows that, at least in the three areas examined, systematic reviews often differ considerably. Readers should be aware that apparently minor decisions in the review process can have major impact.

Are the effects of homeopathy attributable to a statistical artefact? A reanalysis of an observational study.

Background. Cohort studies have reported that patients improve considerably after individualised homeopathic treatment. However, these results may be biased by regression to the mean (RTM). Objective. To evaluate whether the observed changes in previous cohort studies are due to RTM and to estimate RTM adjusted effects. Methods. SF-36 quality-of-life (QoL) data from a German cohort of 2827 chronically diseased adults treated by a homeopath were reanalysed by Mee and Chua's modified t-test. Results. RTM adjusted effects, standardized by the respective standard deviation at baseline, were 0.12 (95% CI: 0.06-0.19, P < 0.001) in the mental and 0.25 (0.22-0.28, P < 0.001) in the physical summary score. Small-to-moderate effects were confirmed for the most individual diagnoses in physical, but not in mental component scores. Under the assumption that the true population mean equals the mean of all actually diseased patients, RTM adjusted effects were confirmed for both scores in most diagnoses. Conclusions. Changes in QoL after treatment by a homeopath are small but cannot be explained by RTM alone. As all analyses made conservative assumptions, true RTM adjusted effects are probably larger than presented.

Comparative effectiveness of homoeopathic vs. conventional therapy in usual care of atopic eczema in children: long-term medical and economic outcomes.

BACKGROUND: One in five children visiting a homeopathic physician suffers from atopic eczema. OBJECTIVES: We aimed to examine the long-term effectiveness, safety and costs of homoeopathic vs. conventional treatment in usual medical care of children with atopic eczema. METHODS: In this prospective multi-centre comparative observational non-randomized rater-blinded study, 135 children (48 homoeopathy, 87 conventional) with mild to moderate atopic eczema were included by their respective physicians. Depending on the specialisation of the physician, the primary treatment was either standard conventional treatment or individualized homeopathy as delivered in routine medical care. The main outcome was the SCORAD (SCORing Atopic Dermatitis) at 36 months by a blinded rater. Further outcomes included quality of life, conventional medicine consumption, safety and disease related costs at six, 12 and 36 months after baseline. A multilevel ANCOVA was used, with physician as random effect and the following fixed effects: age, gender, baseline value, severity score, social class and parents' expectation. RESULTS: The adjusted mean SCORAD showed no significant differences between the groups at 36 months (13.7 95% CI [7.9-19.5] vs. 14.9 [10.4-19.4], p = 0.741). The SCORAD response rates at 36 months were similar in both groups (33% response: homoeopathic 63.9% vs. conventional 64.5%, p = 0.94; 50% response: 52.0% vs. 52.3%, p = 0.974). Total costs were higher in the homoeopathic versus the conventional group (months 31-36 200.54 Euro [132.33-268.76] vs. 68.86 Euro [9.13-128.58], p = 0.005). CONCLUSIONS: Taking patient preferences into account, while being unable to rule out residual confounding, in this long-term observational study, the effects of homoeopathic treatment were not superior to conventional treatment for children with mild to moderate atopic eczema, but involved higher costs.

Homeopathy for depression: a randomized, partially double-blind, placebo-controlled, four-armed study (DEP-HOM).

BACKGROUND: The specific clinical benefit of the homeopathic consultation and of homeopathic remedies in patients with depression has not yet been investigated. AIMS: To investigate the 1) specific effect of individualized homeopathic Q-potencies compared to placebo and 2) the effect of an extensive homeopathic case taking (case history I) compared to a shorter, rather conventional one (case history II) in the treatment of acute major depression (moderate episode) after six weeks. METHODS: A randomized, partially double-blind, placebo-controlled, four-armed trial using a 2×2 factorial design with a six-week study duration per patient was performed. RESULTS: A total of 44 from 228 planned patients were randomized (2∶1∶2∶1 randomization: 16 homeopathic Q-potencies/case history I, 7 placebo/case history I, 14 homeopathic Q-potencies/case history II, 7 placebo/case history II). Because of recruitment problems, the study was terminated prior to full recruitment, and was underpowered for the preplanned confirmatory hypothesis testing. Exploratory data analyses showed heterogeneous and inconclusive results with large variance in the sample. The mean difference for the Hamilton-D after 6 weeks was 2.0 (95%CI -1.2;5.2) for Q-potencies vs. placebo and -3.1 (-5.9;-0.2) for case history I vs. case history II. Overall, no consistent or clinically relevant results across all outcomes between homeopathic Q-potencies versus placebo and homeopathic versus conventional case taking were observed. The frequency of adverse events was comparable for all groups. CONCLUSIONS: Although our results are inconclusive, given that recruitment into this trial was very difficult and we had to terminate early, we cannot recommend undertaking a further trial addressing this question in a similar setting. Prof. Dr. Claudia Witt had full access to all the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis.

Efficacy of injections with Disci/Rhus toxicodendron compositum for chronic low back pain--a randomized placebo-controlled trial.

BACKGROUND: The effectiveness of injection therapy for low-back pain is still debatable. We compared the efficacy of local injections of the homeopathic preparation Disci/Rhus toxicodendron compositum (verum) with placebo injections and with no treatment in patients with chronic low back pain. METHODOLOGY/PRINCIPAL FINDINGS: In a randomized controlled partly double blind multicenter trial patients with chronic low back pain from 9 German outpatient clinics were enrolled and randomly allocated in a 1∶1∶1 ratio to receive subcutaneous injections (verum or placebo) into painful sites on the lower back over 12 treatment sessions within eight weeks, or no treatment (rescue pain medication with paracetamol or NSAIDs). All trial personnel and participants were masked to treatment allocation. The primary outcome measure was the average pain intensity over the last seven days on a visual analogue scale (0-100 mm, 0 = no pain, 100 = worst imaginable pain) after eight weeks. Follow-up was 26 weeks. Primary analysis was by intention to treat. Between August 2007 and June 2008, 150 patients were randomly allocated to three groups (51 verum, 48 placebo and 51 no treatment). The mean baseline-adjusted low back pain intensity at week eight was: verum group 37.0 mm (97.5% CI 25.3;48.8), no treatment group 53.0 (41.8;64.2), and placebo group 41.8 (30.1;53.6). The verum was significantly superior to no treatment (P = 0.001), but not to placebo (P = 0.350). No significant side effects were reported. CONCLUSIONS/SIGNIFICANCE: The homeopathic preparation was not superior to placebo. Compared to no treatment injections resulted in significant and clinical relevant chronic back pain relief. TRIAL REGISTRATION: ClinicalTrials.gov NCT00567736.

Homeopathy for depression--DEP-HOM: study protocol for a randomized, partially double-blind, placebo controlled, four armed study.

BACKGROUND: Homeopathy is often sought by patients with depression. In classical homeopathy, the treatment consists of two main elements: the case history and the prescription of an individually selected homeopathic remedy. Previous data suggest that individualized homeopathic Q-potencies were not inferior to the antidepressant fluoxetine in a sample of patients with moderate to severe depression. However, the question remains whether individualized homeopathic Q-potencies and/or the type of the homeopathic case history have a specific therapeutical effect in acute depression as this has not yet been investigated. The study aims to assess the two components of individualized homeopathic treatment for acute depression, i.e., to investigate the specific effect of individualized Q-potencies versus placebo and to investigate the effect of different approaches to the homeopathic case history. METHODS/DESIGN: A randomized, partially double-blind, placebo-controlled, four-armed trial using a 2 x 2 factorial design with a six-week study duration per patient will be performed. 228 patients diagnosed with major depression (moderate episode) by a psychiatrist will be included. The primary endpoint is the total score on the 17-item Hamilton Depression Rating Scale after six weeks. Secondary end points are: Hamilton Depression Rating Scale total score after two and four weeks; response and remission rates, Beck Depression inventory total score, quality of life and safety at two, four and six weeks. Statistical analyses will be by intention-to-treat. The main endpoint will be analysed by a two-factorial analysis of covariance. Within this model generalized estimation equations will be used to estimate differences between verum and placebo, and between both types of case history. DISCUSSION: For the first time this study evaluates both the specific effect of homeopathic medicines and of a homeopathic case taking in patients with depression. It is an attempt to deal with the challenges of homeopathic research and the results might be useful information in the current discussion about the evidence on homeopathy TRIAL REGISTRATION: ClinicalTrials.gov: NCT01178255.

Homeopathic treatment of patients with migraine: a prospective observational study with a 2-year follow-up period.

OBJECTIVES AND BACKGROUND: The objective of this study was to evaluate treatment details and possible effects of an individualized homeopathic treatment in patients with migraine in usual care. DESIGN: This was a prospective multicenter observational study. Consecutive patients beginning homeopathic treatment in primary care practices were evaluated over 2 years using standardized questionnaires. The data recorded included diagnoses (International Classification of Diseases, Ninth Revision) and current complaints, including their severity (numeric rating scale = 0-10), health-related quality of life (QoL, 36-item Short-Form Health Survey), medical history, consultations, homeopathic and conventional treatments, as well as other health service use. RESULTS: Two hundred and twelve (212) adults (89.2% women), mean age 39.4 +/- 10.7 years were treated by 67 physicians. Patients had suffered from migraine for a period of 15.2 +/- 10.9 years. Most patients (90.0%) were conventionally pretreated. The physician workload included taking the initial patient history (120 +/- 45 minutes), case analysis (40 +/- 47 minutes), and follow-ups (7.3 +/- 7.0, totaling 165.6 +/- 118.8 minutes). Patients received 6.2 +/- 4.6 homeopathic prescriptions. Migraine severity showed marked improvement with a large effect size (Cohen's d = 1.48 after 3 months and 2.28 after 24 months. QoL improved accordingly (Mental Component Score and Physical Component Score after 24 months: 0.42 and 0.45). The use of conventional treatment and health services decreased markedly. CONCLUSIONS: In this observational study, patients seeking homeopathic treatment for migraine showed relevant improvements that persisted for the observed 24 month period. Due to the design of this study, however, it does not answer the question as to whether the effects are treatment specific or not.
