A Randomized, Double-Blind, Placebo-Controlled, Pilot Trial of Individualized Homeopathic Medicines for Cutaneous Warts.

BACKGROUND: Though frequently used in practice, research studies have shown inconclusive benefits of homeopathy in the treatment of warts. We aimed to assess the feasibility of a future definitive trial, with preliminary assessment of differences between effects of individualized homeopathic (IH) medicines and placebos in treatment of cutaneous warts. METHODS: A double-blind, randomized, placebo-controlled trial (n = 60) was conducted at the dermatology outpatient department of D.N. De Homoeopathic Medical College and Hospital, West Bengal. Patients were randomized to receive either IH (n = 30) or identical-looking placebo (n = 30). Primary outcome measures were numbers and sizes of the warts; secondary outcome was the Dermatology Life Quality Index (DLQI) questionnaire measured at baseline, and every month up to 3 months. Group differences and effect sizes were calculated on the intention-to-treat sample. RESULTS: Attrition rate was 11.6% (IH, 3; placebo, 4). Intra-group changes were significantly greater (all p < 0.05, Friedman tests) in IH than placebo. Inter-group differences were statistically non-significant (all p > 0.05, Mann-Whitney U tests) with small effect sizes-both in the primary outcomes (number of warts after 3 months: IH median [inter-quartile range; IQR] 1 [1, 3] vs. placebo 1 [1, 2]; p = 0.741; size of warts after 3 months: IH 5.6 mm [2.6, 40.2] vs. placebo 6.3 [0.8, 16.7]; p = 0.515) and in the secondary outcomes (DLQI total after 3 months: IH 4.5 [2, 6.2] vs. placebo 4.5 [2.5, 8]; p = 0.935). Thuja occidentalis (28.3%), Natrum muriaticum (10%) and Sulphur (8.3%) were the most frequently prescribed medicines. No harms, homeopathic aggravations, or serious adverse events were reported. CONCLUSION: As regards efficacy, the preliminary study was inconclusive, with a statistically non-significant direction of effect favoring homeopathy. The trial succeeded in showing that an adequately powered definitive trial is both feasible and warranted. TRIAL REGISTRATION: CTRI/2019/10/021659; UTN: U1111-1241-7340.

Individualized Homeopathic Medicines in Chronic Rhinosinusitis: Randomized, Double-Blind, Placebo-Controlled Trial.

BACKGROUND: Chronic rhinosinusitis (CRS) is a common disorder, with up to an estimated 134 million Indian sufferers, and having significant impact on quality of life (QOL) and health costs. Despite the evidence favoring homeopathy in CRS being inadequate, it is highly popular. This trial attempts to study the efficacy of individualized homeopathy (IH) medicines in comparison with placebo in patients with CRS. METHODS: A double-blind, randomized (1:1), placebo-controlled, preliminary trial (n = 62) was conducted at the National Institute of Homoeopathy, West Bengal, India. Primary outcome measure was the sino-nasal outcome test-20 (SNOT-20) questionnaire; secondary outcomes were the EQ-5D-5L questionnaire and EQ-5D-5L visual analog scale scores, and five numeric rating scales (0-10) assessing intensity of sneezing, rhinorrhea, post-nasal drip, facial pain/pressure, and disturbance in sense of smell, all measured at baseline and after the 2nd and 4th months of intervention. Group differences and effect sizes (Cohen's d) were calculated on the intention-to-treat sample. RESULTS: Groups were comparable at baseline. Attrition rate was 6.5% (IH: 1, Placebo: 3). Although improvements in both primary and secondary outcome measures were higher in the IH group than placebo, with small to medium effect sizes, the group differences were statistically non-significant (all p > 0.05, unpaired t-tests). Calcarea carbonica, Lycopodium clavatum, Sulphur, Natrum muriaticum and Pulsatilla nigricans were the most frequently prescribed medicines. No harmful or unintended effects, homeopathic aggravations or any serious adverse events were reported from either group. CONCLUSION: There was a small but non-significant direction of effect favoring homeopathy, which ultimately renders the trial as inconclusive. Rigorous trials and independent replications are recommended to arrive at a confirmatory conclusion. [Trial registration: CTRI/2018/03/012557; UTN: U1111-1210-7201].

Homeopathic medicinal products for preventing and treating acute respiratory tract infections in children.

BACKGROUND: Acute respiratory tract infections (ARTIs) are common and may lead to complications. Most children experience between three and six ARTIs annually. Although these infections are self-limiting, symptoms can be distressing. Many treatments are used to control symptoms and shorten illness duration. Most have minimal benefit and may lead to adverse effects. Oral homeopathic medicinal products could play a role in childhood ARTI management if evidence for effectiveness is established. OBJECTIVES: To assess the effectiveness and safety of oral homeopathic medicinal products compared with placebo or conventional therapy to prevent and treat acute respiratory tract infections in children. SEARCH METHODS: We searched CENTRAL (2017, Issue 11) including the Cochrane Acute Respiratory Infections Specialised Register, MEDLINE (1946 to 27 November 2017), Embase (2010 to 27 November 2017), CINAHL (1981 to 27 November 2017), AMED (1985 to December 2014), CAMbase (searched 29 March 2018), British Homeopathic Library (searched 26 June 2013 - no longer operating). We also searched the WHO ICTRP and ClinicalTrials.gov trials registers (29 March 2018), checked references, and contacted study authors to identify additional studies. SELECTION CRITERIA: Double-blind, randomised controlled trials (RCTs) or double-blind cluster-RCTs comparing oral homeopathy medicinal products with identical placebo or self-selected conventional treatments to prevent or treat ARTIs in children aged 0 to 16 years. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included eight RCTs of 1562 children receiving oral homeopathic medicinal products or a control treatment (placebo or conventional treatment) for upper respiratory tract infections (URTIs). Four treatment studies examined the effect on URTI recovery, and four studies investigated the effect on preventing URTIs after one to three months of treatment, followed up for the remainder of the year. Two treatment and two prevention studies involved homeopaths individualising treatment. The other studies used predetermined, non-individualised treatments. All studies involved highly diluted homeopathic medicinal products.We found several limitations to the included studies, in particular methodological inconsistencies and high attrition rates, failure to conduct intention-to-treat analysis, selective reporting, and apparent protocol deviations. We assessed three studies as at high risk of bias in at least one domain, and many had additional domains with unclear risk of bias. Three studies received funding from homeopathy manufacturers; one support from a non-government organisation; two government support; one was cosponsored by a university; and one did not report funding support.Methodological inconsistencies and significant clinical and statistical heterogeneity precluded robust quantitative meta-analysis. Only four outcomes were common to more than one study and could be combined for analysis. Odds ratios (OR) were generally small with wide confidence intervals (CI), and the contributing studies found conflicting effects, so there was little certainty that the efficacy of the intervention could be ascertained. All studies assessed as at low risk of bias showed no benefit from oral homeopathic medicinal products; trials at uncertain and high risk of bias reported beneficial effects.We found low-quality evidence that non-individualised homeopathic medicinal products confer little preventive effect on ARTIs (OR 1.14, 95% CI 0.83 to 1.57). We found low-quality evidence from two individualised prevention studies that homeopathy has little impact on the need for antibiotic usage (N = 369) (OR 0.79, 95% CI 0.35 to 1.76). We also assessed adverse events, hospitalisation rates and length of stay, days off school (or work for parents), and quality of life, but were not able to pool data from any of these secondary outcomes.There is insufficient evidence from two pooled individualised treatment studies (N = 155) to determine the effect of homeopathy on short-term cure (OR 1.31 favouring placebo, 95% CI 0.09 to 19.54; very low-quality evidence) and long-term cure rates (OR 0.99, 95% CI 0.10 to 9.67; very low-quality evidence). Adverse events were reported inconsistently; however, serious events were not reported. One study found an increase in the occurrence of non-severe adverse events in the treatment group. AUTHORS' CONCLUSIONS: Pooling of two prevention and two treatment studies did not show any benefit of homeopathic medicinal products compared to placebo on ARTI recurrence or cure rates in children. We found no evidence to support the efficacy of homeopathic medicinal products for ARTIs in children. Adverse events were poorly reported, so conclusions about safety could not be drawn.

Adverse events were reported inconsistently; however, serious events were not reported. One study found an increase in the occurrence of non-severe adverse events in the treatment group.

Quantitative and Qualitative Pathogenetic Indices for Review of Data Derived from Homeopathic Pathogenetic Trials.

INTRODUCTION: Analysis of data derived from homeopathic pathogenetic trials (HPTs, homeopathic drug provings) has been a challenge. Most parts of the homeopathic pharmacopeia were sourced from Hahnemann's Materia Medica Pura (1825-1833), TF Allen's Encyclopedia (1874) and Constantine Hering's Materia Medica (1879-1891), well before randomised controlled trials were in use. As a result, such studies and their outcomes harbour a large risk of inclusion of unreliable symptoms. AIMS AND OBJECTIVE: The main purpose of this article is to introduce Quantitative and Qualitative Pathogenetic Indices to improve the method of analysis of symptoms. MATERIALS AND METHODS: The data from HPTs for human immunodeficiency virus nosode, hepatitis C nosode, capsaicin alkaloids (capsaicin and dihydrocapsaicin) and hydroquinone (HQ) were extracted and analysed in terms of novel Qualitative and Quantitative Pathogenetic Indices. Taken into the consideration were the qualitative aspect of a symptom (i.e. its intensity), and the quantitative aspect by calculating the number of symptoms per volunteer per day. The pathogenetic effects and data evaluation indices were calculated for each HPT. A comparison was made of symptoms of verum versus placebo provers in terms of their quantity and quality. RESULTS: Four HPTs involving 81 volunteers (56 on verum and 25 on placebo) generated 555 symptoms or pathogenetic effects (excluding run-in phase symptoms), of which 448 (81%) were reported by volunteers who were in the verum arm, and 107 (19%) were reported by volunteers on placebo. The overall mean incidence of pathogenetic effects for the four HPTs was thus 8 per verum prover and 4.28 per placebo prover. The corresponding mean Quantitative Pathogenetic Index was 0.23 symptoms per volunteer per day for the verum arm and 0.12 symptoms per volunteer per day for the placebo arm. The overall mean incidence of pathogenetic effects in the run-in phase was less. The overall mean Qualitative Pathogenetic Index (number of symptoms, of a given intensity, per volunteer per day) for the verum arm was 0.09 versus 0.05 for the placebo arm. CONCLUSION: The symptoms exhibited by volunteers in the verum arm were more numerous and more intense than those in the placebo arm. An innovative and logical method of reporting of symptoms and analysis has been introduced by the use of these pathogenetic indices, which can be used in future as measurement tools for analysis of data from HPTs.

Assessment of Likelihood Ratio for Four Contact Dermatitis Symptoms of Vinca Minor.

BACKGROUND: Contact dermatitis (CD) is a frequently occurring medical condition, for which Vinca minor (VM) is one of the recommended homeopathic medicines. However, the symptoms indicating this medicine have not yet been assessed systematically. Likelihood ratio (LR), based on Bayesian statistics, may yield better estimation of a medicine's indication than the existing method of entry of symptoms into materia medica and repertories. METHODS: We investigated LRs of four CD symptoms of VM: (1) great sensitiveness of skin, with redness and soreness from slightest rubbing; (2) weeping eczema with foul, thick crusts; (3) itching amelioration in open air; and (4) CD of scalp. An observational, prospective, patient-outcome study was conducted in five different practice settings on 390 CD patients over 18 months using three outcomes-Glasgow Homeopathic Hospital Outcome Scale (GHHOS), Scoring Atopic Dermatitis (SCORAD), and Dermatology Life Quality Index (DLQI), assessed at baseline, after 3 and 6 months. The LR of each of the four symptoms was estimated as per the patient-rated outcomes on GHHOS. RESULTS: Seventy-four VM and 316 non-VM cases were analyzed. Estimated LRs were as follows: symptom 1, 1.29 (95% confidence interval [CI]: 0.65 to 2.60); symptom 2, 1.48 (95% CI: 0.80 to 2.74); symptom 3, 1.70 (95% CI: 0.94 to 3.07); symptom 4, 1.36 (95% CI: 0.74 to 2.51). There were statistically significant reductions in SCORAD and DLQI scores over 3 and 6 months. CONCLUSION: There was insufficient evidence to attribute any of the four assessed symptoms clearly to VM. Though non-significant, a high LR was observed for "itching amelioration in open air" (symptom 3). Symptoms in the homeopathic materia medica for VM are perhaps over-represented. More research of this nature is warranted.

Homeopathy for Perennial Asthma in Adolescents: Pilot Feasibility Study Testing a Randomised Withdrawal Design.

INTRODUCTION: Previous findings from a pragmatic trial suggest that usual care compared with usual care plus individualised homeopathy is not a feasible design to address homeopathic interventions for asthma. OBJECTIVE: The main purpose of this article was to investigate the feasibility of the randomised withdrawal design as a strategy to assess the effectiveness of a standardised clinical-pharmaceutical homeopathic protocol (Organon.modus) on perennial asthma in adolescents. METHODS: Randomised withdrawal, double-blind, parallel, placebo-controlled, 12-week study. Patients: 12 to 17 years old adolescents, with the diagnosis of perennial asthma, using inhalatory beclomethasone (plus fenoterol for wheezing episodes), who achieved 3 months of well-controlled asthma, after a variable period of individualised homeopathic treatment according to Organon.modus protocol. Setting: a secondary care medical specialist centre. Intervention: continuation with the individualised homeopathic medicine or with indistinguishable placebo during 12 weeks of beclomethasone step-down. Primary outcome: number of days of well-controlled asthma. Secondary measures: number of days of fenoterol use, number of visits to an emergency service (without hospitalisation) and percentage of patients excluded due to an exacerbation characterising a partly controlled asthma. Tolerability was assessed by Adverse Events, registered at every visit. RESULTS: Nineteen patients were randomised to continue treatment with homeopathy and 21 with placebo. Effectiveness measures for the homeopathy and placebo groups respectively were median number of days of good clinical control: 84 versus 30 (p = 0.18); median number of days of fenoterol use per patient: 3 versus 5 (p = 0.41); visits to an emergency room: 1 versus 6 (p = 0.35); percentage of exclusion due to partly controlled asthma: 36.8% versus 71.4% (p = 0.05). Few Adverse Events were reported. CONCLUSIONS: This pilot study supports the feasibility of the double-blind randomised withdrawal design in studies investigating homeopathy on teenage asthma, when performed by specialists following a standardised clinical-pharmaceutical homeopathic protocol. CLINICAL TRIAL REGISTRATION: RBR-6XTS8Z.

Randomized, blinded, controlled clinical trial shows no benefit of homeopathic mastitis treatment in dairy cows.

Mastitis is one of the most common diseases in dairy production, and homeopathic remedies have been used increasingly in recent years to treat it. Clinical trials evaluating homeopathy have often been criticized for their inadequate scientific approach. The objective of this triple-blind, randomized controlled trial was to assess the efficacy of homeopathic treatment in bovine clinical mastitis. The study was conducted on a conventionally managed dairy farm between June 2013 and May 2014. Dairy cows with acute mastitis were randomly allocated to homeopathy (n = 70) or placebo (n = 92), for a total of 162 animals. The homeopathic treatment was selected based on clinical symptoms but most commonly consisted of a combination of nosodes with Streptococcinum, Staphylococcinum, Pyrogenium, and Escherichia coli at a potency of 200c. Treatment was administered to cows in the homeopathy group at least once per day for an average of 5 d. The cows in the placebo group were treated similarly, using a placebo preparation instead (lactose globules without active ingredients). If necessary, we also used allopathic drugs (e.g., antibiotics, udder creams, and anti-inflammatory drugs) in both groups. We recorded data relating to the clinical signs of mastitis, treatment, time to recovery, milk yield, somatic cell count at first milk recording after mastitis, and culling. We observed cows for up to 200 d after clinical recovery. Base-level data did not differ between the homeopathy and placebo groups. Mastitis lasted for an average of 6 d in both groups. We observed no significant differences in time to recovery, somatic cell count, risk of clinical cure within 14 d after disease occurrence, mastitis recurrence risk, or culling risk. The results indicated no additional effect of homeopathic treatment compared with placebo. The advantages or disadvantages of homeopathy should be carefully assessed for individual farms.

Model validity of randomised placebo-controlled trials of individualised homeopathic treatment.

BACKGROUND: Though potentially an important limitation in the literature of randomised controlled trials (RCTs) of homeopathy, the model validity of homeopathic treatment (MVHT) has not previously been systematically investigated. OBJECTIVE: As an integral part of a programme of systematic reviews, to assess MVHT of eligible RCTs of individualised homeopathic treatment. METHODS: From 46 previously identified papers in the category, 31 papers (reporting a total of 32 RCTs) were eligible for systematic review and were thus the subject of the study. For each of six domains of assessment per trial, MVHT was judged independently by three randomly allocated assessors from our group, who reached a final verdict by consensus discussion as necessary. RESULTS: Nineteen trials were judged overall as 'acceptable' MVHT, nine as 'uncertain' MVHT, and four as 'inadequate' MVHT. CONCLUSIONS: These results do not support concern that deficient MVHT has frequently undermined the published findings of RCTs of individualised homeopathy. However, the 13 trials with 'uncertain' or 'inadequate' MVHT will be a focus of attention in supplementary meta-analysis. New RCTs of individualised homeopathy must aim to maximise MVHT and to enable its assessment through clear reporting.

Hahnemann and placebo.

Samuel Hahnemann (1755-1843) known today as the founder of homoeopathy, was - as far as we know - the first physician who administrated placebos to his patient on a systematic and regular basis. This study is based upon unpublished documents (e.g. patients' letters) in the Archives of the Institute for the History of Medicine of the Robert Bosch Foundation in Stuttgart. It also profited from the critical edition of Hahnemann's case journals and the editorial comments which have also been published in this series. Hahnemann differentiated clearly between homeopathic drugs and pharmaceutical substances which he considered as sham medicine (e.g. milk sugar). A close look at Hahnemann's case journals reveals that the percentage of placebo prescriptions was very high (between 54 and 85 percent). In most instances Hahnemann marked placebos with the paragraph symbol (§). The rationale behind this practice was that Hahnemann had encountered the well-known problem that patients were used to taking medicine on a daily basis as it was typical for the age of heroic medicine. The main reason for giving placebo was therefore to please the impatient patient who was used to frequent medications in allopathic medicine, not only every day but sometimes also hourly.

The effect of a homeopathic complex on psychophysiological onset insomnia in males: a randomized pilot study.

CONTEXT: Psychophysiological onset insomnia (PI) is defined as sleeplessness exceeding 30 min due to learned, sleep-preventing behaviors and hyperarousal at bedtime. This common condition significantly impacts sufferers' health, occupational performance, and interpersonal relationships. Conventional treatment with hypnotics has many shortcomings. Homeopathic medication may present an alternative treatment for this condition. OBJECTIVE: The study intended to determine the effect of a homeopathic complex on PI. DESIGN: The research team designed a randomized, double-blind, placebo-controlled, 4-wk pilot study, using matched pairs. SETTING: The study took place at the Homeopathy Health Clinic at the University of Johannesburg in Johannesburg, South Africa. PARTICIPANTS: Forty-six males aged between 18 and 40 y with chronic PI were recruited; 28 completed the study- placebo group (n = 14) and experimental group (n = 14). INTERVENTIONS: The homeopathic complex was made in 20% alcohol. The placebo consisted of the unmedicated vehicle only. OUTCOME MEASURES: The study used the Pre-sleep Arousal Scale (PSAS) and the Sleep Diary (SD), which assessed sleep-onset latency. RESULTS: The experimental group showed a statistically significant improvement in presleep arousal as well as sleep onset latency over the 4 wks of the study. The Wilcoxon signed-rank test revealed that the improvement occurred gradually. Intergroup analysis showed through both the PSAS and the SD that the experimental group had outperformed the placebo group by day 28 of the study. CONCLUSION: Findings suggest that daily use of the homeopathic complex does have an effect over a 4-wk period on physiological and cognitive arousal at bedtime as well as on sleep onset latency in PI sufferers. Further research on the use of this complex for PI is warranted before any definitive conclusions can be drawn.

Use of placebo interventions in primary care in Poland.

OBJECTIVE: The aim of the study was to investigate the behavior, beliefs and attitudes of Polish primary care physicians concerning the use of placebo interventions. SUBJECTS AND METHODS: A total of 220 Polish primary care physicians (internists, specialists in family medicine and pediatricians) were asked to participate in a questionnaire survey and 171 agreed to do so. The questionnaire was a self-report of the behavior, beliefs and attitudes of physicians concerning the use of placebo interventions in clinical practice. The percentages are based on the actual number of respondents to each question. RESULTS: Of 169 respondents, 135 (80%) declared that they used or prescribed placebo interventions, with 20/169 (12%) doing so almost every day, 51/169 (30%) once a week and 44/169 (26%) once a month. The most common placebos used were vitamins (86/135, 66%) and homeopathy (73/135, 56%). Among the participants, 114/129 (84%) reported that the placebos were effective, with only 10/129 (8%) considering them rarely effective; 75/139 (54%) of the physicians considered placebo interventions to be effective only in patients with subjective symptoms, 116/139 (73%) indicated that individual traits of patients were decisive factors in the effectiveness of placebo interventions, and 103/159 (65%) thought that the expectations of patients were of importance. A total of 128/170 (75%) respondents thought that the mechanism of placebo effects was purely psychological. CONCLUSION: The use and prescription of placebo interventions seemed to be very common among Polish primary care physicians studied and they generally had positive attitudes towards their use and effectiveness.

Treating menopausal symptoms with a complex remedy or placebo: a randomized controlled trial.

OBJECTIVE: To evaluate the efficacy and safety of a complex remedy compared with placebo to treat menopausal symptoms. METHODS: A total of 102 peri- and postmenopausal women requiring treatment for menopausal symptoms were randomized to receive a complex anthroposophic remedy prepared in the homeopathic manner (Apis regina tota GL D4, Argentum metallicum D5, Ovaria bovis GL D4), 3 × 10 globuli daily (2 × 12 weeks) and placebo (12 weeks) in different orders of remedy (R) and placebo (P) (1: R/R/P, 2: P/R/R, 3: R/P/R). The primary endpoint was change in climacteric symptoms assessed by the Menopause Rating Scale II (MRS II) after 12 weeks. Secondary endpoints were changes of symptoms and safety throughout the study. RESULTS: Reduction of symptoms after 12 weeks did not differ between remedy and placebo (total score MRS II: -1.4, 95% confidence interval (CI) -2.8 to 0 vs. -2.3, 95% CI -4.4 to -0.3, p = 0.441) and had no clinical relevance (defined as reduction in MRS II ≥ -3.5). Comparison of secondary outcomes at 12 weeks between remedy and placebo or between groups after the 2nd or 3rd period compared to previous periods did not differ. Treatment with remedy for 24 consecutive weeks did not reach clinical relevance either. However, total reduction of symptoms after three periods in Group 1 (R/R/P) (-5.0, 95% CI -7.5 to -2.5) and Group 2 (P/R/R) (-5.9, 95% CI -8.7 to -3.1) reached clinical relevance whereas almost no decrease of symptoms after three periods was seen in Group 3 (R/P/R) (-0.5, 95% CI -2.9 to 1.9). CONCLUSIONS: Treatment with the complex remedy for 12 or 24 weeks did not result in clinically significant improvement of menopausal symptoms.

A randomized, double-blind, parallel trial comparing capsaicin nasal spray with placebo in subjects with a significant component of nonallergic rhinitis.

OBJECTIVE: To investigate the efficacy and safety of ICX72 or Sinus Buster, a proprietary homeopathic preparation of Capsicum annum and Eucalyptol, versus placebo administered continuously over 2 weeks in subjects with a significant component of nonallergic rhinitis (NAR). METHODS: Forty-two consented subjects meeting inclusion/exclusion criteria were randomized to ICX72 (n = 20) or control (n = 22) administered twice daily over 2 weeks. The primary endpoint was change in total nasal symptom scores (TNSS) from baseline to end of study. Secondary endpoints included changes in individual symptom scores (ISS) over 2 weeks and average time to first relief. Mean TNSS and ISS were recorded after single dosing at different intervals over 60 minutes. Rhinitis quality-of-life, rescue medication, and safety endpoints were analyzed. RESULTS: ICX72 versus placebo subjects exhibited significant differences in changes from baseline to end of study for TNSS and each ISS (P < .01), had an average time to first relief of 52.6 seconds (P < .01), and improvement in nasal congestion, sinus pain, sinus pressure, and headache at 5, 10, 15, and 30 minutes, persisting at 60 minutes for nasal congestion and sinus pain (P < .05). No difference between groups in adverse events or rescue medication was observed. ICX72 versus placebo subjects experienced no rebound congestion or impaired olfaction at the end of the study. CONCLUSION: This is the first controlled trial demonstrating intranasal capsaicin, when used continuously over 2 weeks, rapidly and safely improves symptoms in rhinitis subjects with a significant NAR component.

Individualized Homeopathic Medicines in Stage I Essential Hypertension: A Double-Blind, Randomized, Placebo-Controlled Pilot Trial.

Objective: The present study assessed the feasibility of a definitive placebo-controlled trial for evaluating individualized homeopathy (IH) in stage I hypertension (HTN). Design: Double-blind, randomized (IH: 34, placebo: 34), placebo-controlled, parallel arms, pilot trial. Settings/Location: National Institute of Homoeopathy, India. Subjects: Patients suffering from stage I HTN. Interventions: IH and identical-looking placebo. Outcome measures: Feasibility issues, blood pressure (BP) and Measure Yourself Medical Outcome Profile-2 (MYMOP-2) were assessed for 6 months. Results: The recruitment and retention rates were 44.4% and 85.3%, respectively. Group differences were seemingly higher in the IH group than in the placebo group. Conclusions: Despite challenges in recruitment, an adequately powered efficacy trial appears feasible in the future.

Pilot study of the effect of individualised homeopathy on the pruritus associated with atopic dermatitis in dogs.

Twenty dogs with confirmed atopic dermatitis were treated with homeopathy. In the first phase of this pilot study, all of the dogs were treated by a veterinary homeopath with individualised remedies prescribed on the basis of the dog's cutaneous signs and constitutional characteristics. The response to treatment was assessed by scoring the severity of pruritus from 0 to 10 on a validated scale. The dogs were evaluated at monthly intervals for at least two months. In 15 cases, the owners reported no improvement following homeopathic treatment. In the other five cases, the owners believed that the homeopathic treatment was associated with a substantial improvement, and reported reductions in pruritus scores ranging from 64 to 100 per cent. These five dogs were selected for the second phase of the study, in which homeopathic remedies were tested against placebos in a randomised and blinded trial. In one of these dogs, atopic dermatitis resolved completely and so this dog could not participate in phase 2; another dog was euthanased because of status epilepticus before phase 2 could be started. In the remaining three cases, the owners correctly distinguished between the placebo and homeopathic remedies, and reported reductions in the pruritus score of 0, 0.2 and 0.8 following placebo treatment and 4.3, 2.4 and 3.0, respectively, following the remedy.

"Homeopathy is not placebo effect": proof of the scientific evidence for homeopathy [Editorial]

Homeopathy has been a medical practice recognized worldwide for more than two centuries, providing care, teaching, and research activities in several health institutions and medical schools. It employs a clinical approach based on non-conventional and complementary scientific principles (principle of therapeutic similitude, homeopathic pathogenetic experimentation, and use of dynamized doses and individualized medicines), with the aim of awakening a curative response from the body against its own disorders or diseases1. Homeopathy proposes to understand and treat the sick-disease binomial according to a vitalist, globalizing, and humanist anthropological approach, valuing the different aspects of the sick individuality (mental, general, and physical) and contributes to maintain health and organic homeostasis, acting as a therapeutic alternative for various health disorders2,3. However, to achieve this objective, homeopathic therapy must be well conducted and follow the epistemological premises of the homeopathic model1, among which include applying therapeutic similitude/similarity between the set of signs and symptoms of the sick individual (characteristic symptomatic totality of the sick-disease binomial) and the set of pathogenetic signs and symptoms caused by the medicine in the healthy individual (homeopathic pathogenetic experimentation), meaning individualized homeopathic treatment.

A double-blind placebo-controlled study into the efficacy of a homeopathic remedy for fear of firework noises in the dog (Canis familiaris).

Seventy-five dogs that showed a fear response to fireworks participated in a double-blinded, placebo-controlled clinical trial to assess the efficacy of a homeopathic remedy for the alleviation of their behavioural signs. Dogs were randomly assigned to one of two treatments; the homeopathic treatment or the placebo treatment. At the baseline assessments the owners identified the behavioural signs of fear that their dogs normally displayed in response to fireworks, rated their frequency and intensity, and assessed the global severity of their dog's responses. These measures were repeated at the final assessment and owners also completed weekly diaries for the length of the trial. There were significant improvements in the owners' rating of 14/15 behavioural signs of fear in the placebo treatment group and all 15 behavioural signs in the homeopathic treatment group. Both treatment groups also showed significant improvement in the owners' rating of the global severity of their dog's responses. However, there was no significant difference in the response seen between the two treatment groups.

Estrógeno potenciado en el tratamiento homeopático del dolor pélvico asociado a endometriosis: un estudio aleatorizado, doble ciego, controlado con placebo, de 24 semanas / Potentiated estrogen in the homeopathic treatment of pelvic pain associated with endometriosis: a 24-week randomized, double-blind, placebo-controlled study

Evaluar la eficacia y seguridad del estrógeno potenciado en comparación con el placebo en el tratamiento homeopático del dolor pélvico asociado a endometriosis (EAPP, por sus siglas en inglés). Diseño del estudio: El presente fue un estudio clínico aleatorizado, doble ciego, controlado con placebo, de 24 semanas, el cual incluyó a 50 mujeres de entre 18 y 45 años de edad con diagnóstico de endometriosis infiltrante profunda con base en ultrasonido transvaginal o imágenes de resonancia magnética después de preparación intestinal, así como puntaje ≥ 5 en una escala visual analógica (VAS: rango de 0 a 10 puntos) para el dolor pélvico asociado con la endometriosis. Se administró estrógeno potenciado (12cH, 18cH y 24cH) o placebo dos veces al día por vía oral. La medida principal de resultado fue el cambio en la severidad de los puntajes parcial y global de EAPP (VAS) de la línea basal a la semana 24, determinada como la diferencia en el puntaje medio de cinco modalidades de dolor pélvico crónico (dismenorrea, dispareunia profunda, dolor pélvico no cíclico, dolor intestinal cíclico y/o dolor urinario cíclico). Las medidas secundarias de resultado fueron la diferencia media de puntaje para la calidad de vida evaluada con el Cuestionario de Salud SF-36, los síntomas de depresión en el Inventario de la Depresión de Beck (BDI) y los síntomas de ansiedad en el Inventario de Ansiedad de Beck (BAI). Resultados: El puntaje global de EAPP (VAS: rango de 0 a 50 puntos) se redujo en 12.82 (p < 0.001) en el grupo tratado con estrógeno potenciado de la línea basal a la semana 24. El grupo que utilizó estrógeno potenciado también presentó una reducción en el puntaje parcial (VAS: rango de 0 a 10 puntos) en tres modalidades de EAPP: dismenorrea (3.28; p < 0.001), dolor pélvico no cíclico (2.71; p = 0.009) y dolor intestinal cíclico (3.40; p < 0.001). El grupo de placebo no mostró cambio significativo alguno en los puntajes global o parcial de EAPP. Además, el grupo de estrógeno potenciado mostró un mejoramiento significativo en tres de ocho ámbitos de SF-36 (dolor de cuerpo, vitalidad y salud mental) y síntomas de depresión (BDI). El grupo de placebo no mostró un mejoramiento significativo a este respecto. Estos resultados demuestran la superioridad del estrógeno potenciado sobre el placebo. Se asociaron pocos eventos adversos con el estrógeno potenciado. Conclusiones: El estrógeno potenciado (12cH, 18cH y 24cH) en dosis de 3 gotas dos veces al día durante 24 semanas fue significativamente más efectivo que el placebo para reducir el dolor pélvico asociado con la endometriosis.

To evaluate the efficacy and safety of potentized estrogen compared to placebo in homeopathic treatment of endometriosis-associated pelvic pain (EAPP). Study design: The present was a 24-week, randomized, doubleblind, placebocontrolled trial that included 50 women aged 18-45 years old with diagnosis of deeply infiltrating endometriosis based on magnetic resonance imaging or transvaginal ultrasound after bowel preparation, and score ≥ 5 on a visual analogue scale (VAS: range 0 to 10 points) for endometriosis-associated pelvic pain. Potentized estrogen (12cH, 18cH and 24cH) or placebo was administered twice daily per oral route. The primary outcome measure was change in the severity of EAPP global and partial scores (VAS) from baseline to week 24, determined as the difference in the mean score of five modalities of chronic pelvic pain (dysmenorrhea, deep dyspareunia, non-cyclic pelvic pain, cyclic bowel pain and/or cyclic urinary pain). The secondary outcome measures were mean score difference for quality of life assessed with SF-36 Health Survey Questionnaire, depression symptoms on Beck Depression Inventory (BDI), and anxiety symptoms on Beck Anxiety Inventory (BAI). Results: The EAPP global score (VAS: range 0 to 50 points) decreased by 12.82 (p < 0.001) in the group treated with potentized estrogen from baseline to week 24. Group that used potentized estrogen also exhibited partial score (VAS: range 0 to 10 points) reduction in three EAPP modalities: dysmenorrhea (3.28; p < 0.001), non-cyclic pelvic pain (2.71; p = 0.009), and cyclic bowel pain (3.40; p < 0.001). Placebo group did not show any significant changes in EAPP global or partial scores. In addition, the potentized estrogen group showed significant improvement in three of eight SF-36 domains (bodily pain, vitality and mental health) and depression symptoms (BDI). Placebo group showed no significant improvement in this regard. These results demonstrate superiority of potentized estrogen over placebo. Few adverse events were associated with potentized estrogen. Conclusions: Potentized estrogen (12cH, 18cH and 24cH) at a dose of 3 drops twice daily for 24 weeks was significantly more effective than placebo for reducing endometriosis-associated pelvic pain.
