Individualized Homeopathic Medicines in the Treatment of Generalized Anxiety Disorder: A Double-Blind, Randomized, Placebo-Controlled, Pilot Trial

INTRODUCTION

Evidence favoring homeopathy in generalized anxiety disorder (GAD) remains scarce. The objective of this pilot trial was to test feasibility of a definitive trial in future. We also experimented whether individualized homeopathic medicines (IH) plus psychological counseling (PC) can produce significantly different effects beyond placebo plus PC in the treatment of GAD.

METHODS

A double-blind, randomized, placebo-controlled, parallel arm, pilot trial was conducted on 62 GAD patients at the National Institute of Homoeopathy, India. GAD-7 questionnaire and Hamilton Anxiety Scale (HAM-A) were used as the primary and secondary outcomes, respectively, measured at baseline and 3 months. Patients received either IH plus PC (n = 31) or identical-looking placebo plus PC (n = 31). Intention-to-treat sample was analyzed to detect group differences using unpaired t tests.

RESULTS

Recruitment and retention rates were 56 and 90%, respectively. Mean age was 31.5 years; 56.5% were male. GAD-7 reductions were non-significantly higher in IH than placebo (p = 0.122). Group differences on HAM-A favored IH significantly (p = 0.018). Effect sizes were small to medium. Calcarea carbonica was the most frequently indicated medicine. No serious adverse events happened.

CONCLUSIONS

A small but positive direction of anxiolytic effect was observed favoring homeopathy over placebo. A definitive trial appeared feasible in future.

Individualized homeopathic medicines and Urtica urens mother tincture in treatment of hyperuricemia: an open, randomized, pragmatic, pilot trial

OBJECTIVES

The quality of management of hyperuricemia has remained sub-optimal owing to unavoidable toxicities, limitations, and dearth of novel advances. Homeopathy has remained under-researched in hyperuricemia. We investigated the clinical effectiveness of three treatment regimens - individualized homeopathy (IH), Urtica urens mother tincture (UUMT), and both (IH + UUMT) along with lifestyle modifications in a sample of 90 patients with hyperuricemia.

METHODS

An open, randomized (1:1:1), 3 parallel arms (IH, UUMT, and IH + UUMT), pragmatic trial was conducted at National Institute of Homoeopathy, Kolkata. Outcome measures were serum uric acid (primary), Gout Assessment Questionnaire version 2 (GAQ2, secondary), and Measure Yourself Medical Outcome Profile version 2 (MYMOP2, secondary); all measured at baseline, and after 3 and 6 months. Intention- to-treat sample was analyzed to detect group differences by unpaired t tests.

RESULTS

Attrition rate was 8.9% (IH: 3, UUMT: 3, IH + UUMT: 2). Groups were comparable at baseline. Reductions in serum uric acid over 3 months were comparatively higher (p=0.057) in the UUMT group than others, however, the differences were narrowed over 6 months (p=0.119). Per protocol analysis of serum uric acid level revealed similar trend of significantly higher reduction in the UUMT group than the other two (3 months: p=0.001; 6 months: p=0.007). No significant differences existed in reductions of GAQ2 scores among the three groups. Few significant differences were detected in MYMOP scores over 3 months favoring IH against others (symptom 2, p=0.001 and wellbeing score, p=0.002), and also over 6 months favoring IH + UUMT against others (symptom 1, p<0.001).

CONCLUSION

Although all three therapies showed similar improvements, the IH + UUMT group had more positive direction of effects than IH or UUMT alone; however, no definite conclusion could be arrived at. Further trials are warranted with larger sample size. Trial registration: CTRI/2018/05/014026.

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].

Clinical trials of homeopathy in urological disorders: a systematic review

OBJECTIVES

Homeopathy remains one of the most sought after therapies for urological disorders. The aim of this paper was to systematically review the available clinical researches of homeopathy in the said conditions.

CONTENT

Relevant trials published between Jan 1, 1981 and Dec 31, 2016 (with further extension up to Dec 31, 2017) was identified through a comprehensive search. Internal validity of the randomized trials and observational studies was assessed by The Cochrane Collaboration's tool and methodological index for non-randomized studies (MINORS) criteria respectively, homeopathic model validity by Mathie's six judgmental domains, and quality of homeopathic individualization by Saha's criteria.

SUMMARY

Four controlled (three randomized and one sequentially allocated controlled trial) trials were reviewed and 14 observational studies alongside - all demonstrated positive effect of homeopathy. Major focus areas were benign prostatic hypertrophy and renal stones. One of the four controlled trials had 'adequate' model validity, but suffered from 'high' risk of bias. None of the non-randomized studies was tagged as 'ideal' as all of those underperformed in the MINORS rating. Nine observational studies had 'adequate' model validity and quality criteria of individualization. Proof supporting individualized homeopathy from the controlled trials remained promising, still inconclusive.

OUTLOOK

Although observational studies appeared to produce encouraging effects, lack of adequate quality data from randomized trials hindered to arrive at any conclusion regarding the efficacy or effectiveness of homeopathy in urological disorders. The findings from the RCTs remained scarce, underpowered and heterogeneous, had low reliability overall due to high or uncertain risk of bias and sub-standard model validity. Well-designed trials are warranted with improved methodological robustness.

An open-label randomized pragmatic non-inferiority pilot trial to compare the effectiveness of Dysentery compound with individualized homeopathic medicines in irritable bowel syndrome

Background Irritable Bowel Syndrome (IBS) is a prevalent gastro-intestinal disorder characterized by recurrent abdominal pain, bloating, altered bowel function and myriad of gastro-intestinal symptoms. Dysentery compound (DC), a 'bowel nosode', is one of the homeopathic medicines to treat IBS, but remained under-researched. We hypothesized that DC would be non-inferior to individualized homeopathy (IH) in treatment of IBS. Method An open, randomized (1:1), parallel arms, pragmatic, non-inferiority, pilot trial was conducted to compare the effectiveness of DC with IH medicines in 60 IBS patients. IBS Quality of Life (IBS-QOL) questionnaire was used as the outcome measure; assessed at baseline and after 3 months. Comparative analysis was carried out on the primary outcome to detect non-inferiority by one-tailed t test at alpha=5% with a prefixed margin (Δ) of 1.0 based on assumption. Results Six subjects dropped out. Groups were comparable at baseline (all p>0.01). Though intra-group changes were higher favoring IH over DC, group differences were statistically non-significant (all p>0.01). Non-inferiority was not demonstrated by DC against IH over 3 months (mean difference= -3.3, SE=5.2, lower 95% confidence limit -11.9, t= -0.453, p=0.674). No adverse events were reported from either group. Conclusion Non-inferiority of DC against IH in treatment of IBS was not demonstrated though it appeared as safe; still, being a pilot trial, no definite conclusion could be drawn. Further exploration of both efficacy and effectiveness of either of the therapies is necessary by adequately powered trials and independent replications.

Importance of Temperament in Individualized Homeopathic Prescription: Evaluation by an Open, Randomized, Pilot Trial

BACKGROUND

The importance of temperament in the selection of an individualized homeopathic medicine has not been evaluated systematically. The current study explored this under-researched area.

MATERIALS AND METHODS

A prospective, open, randomized (1:1), two parallel arms, pilot trial was performed on patients suffering from various chronic diseases. Each patient's temperament was assessed using a newly developed "temperament diagnostic questionnaire". Outcome measures were health status using the EQ-5D-5L questionnaire and a visual analog scale (VAS) of patient's self-rated health, measured at baseline and at 3 months. Homeopathic medicines were prescribed on the basis of individualization, randomly with or without accounting for individual temperament, and patients grouped accordingly (temperament(+) and temperament(-)). Baseline comparability of the two groups was checked, followed by analysis of group differences. A p-value < 0.01 was considered as statistically significant.

RESULTS

Fifty protocol-compliant patients were analyzed. The two groups were comparable at baseline. Over 3 months of intervention, there was significant improvement (p < 0.01) in each group. Though improvement in the EQ-5D-5L score was greater in the temperament(+) group (mean difference, 2.4; 95% confidence interval [CI], 0.2 to 4.5), the change did not achieve the threshold for statistical significance (p = 0.029). Improvement in VAS score was significantly greater in the temperament(+) group than in temperament(-) patients (mean difference, 15.2; 95% CI, 4.9 to 25.4; p = 0.004).

CONCLUSION

Considering temperament as a key element of individualized prescription may enhance health improvement from homeopathic treatment in chronic diseases. Independently replicated rigorous trials with validated scales are warranted.

An Open-Label Observational Trial to Evaluate the Possible Effects of Individualized Homoeopathic Medicines in Symptomatic Nasal Polyp

Introduction: Nasal polyps presenting with chronic rhino-sinusitis (CRS) is a commonly encountered condition characterized by nasal obstruction, loss of sense of smell (anosmia), postnasal drip, headache, and sleep disorders. Possibly 60-65% of the populations suffering from CRS has predisposition to nasal polyps. Homoeopathic literature claims to offer successful treatment of nasal polyps; but scarcely subjected to systematic research. Materials and Methods: A prospective, open, non-randomized, single arm, observational trial of pre-post comparison design was conducted on 44 patients suffering from symptomatic nasal polyps. Sino-nasal outcome test (SNOT-20) and European Quality of Life (EQ-5D-5L) questionnaires were taken as the primary and secondary outcome measures respectively; assessed at baseline and after 3 months. Individualized homoeopathic medicines were prescribed on ‘totality of symptoms’. Intention to treat sample was subjected to statistical analysis. Data distribution was examined. Non-parametric Wilcoxon signed rank test and post hoc parametric paired t test were used accordingly. P values less than 0.05 were considered as statistically significant. Results: Forty four patients were enrolled; 4 dropped out. Skiagrams revealed complete regressions of polyps in 23 (58%) cases. Statistically significant improvements were observed in both the subjective patient-rated outcomes – mean reduction of SNOT-20 scores by 19.9 [sd 15.5; 95% CI 15.5 to 24.2; P < 0.001], EQ-5D-5L questionnaire score by 0.9 [sd 2.6; 95% CI 0.1 to 1.7; P = 0.029]; and EQ-5D-5L VAS by 14.4 [sd 4.7; 95% CI 12.9 to 15.9; P < 0.001]. Conclusion: Homoeopathic medicines showed promising treatment effect in symptomatic nasal polyps. Randomized trials are warranted.

Efficacy of individualized homeopathic treatment of insomnia: Double-blind, randomized, placebo-controlled clinical trial

BACKGROUND

Insomnia is the most common sleep-related complaint associated with impaired day-time functioning, reduced quality of life, increased morbidity and substantial societal cost. We evaluated whether individualized homeopathy (IH) could produce significant effect beyond placebo in treatment of insomnia.

METHODS

In this double-blind, randomized, placebo-controlled, two parallel arms trial, 60 patients were randomized to receive either IH/verum or control/placebo (1:1). Patient-administered sleep diary (6 items; 1: latency to fall asleep, 2: minutes awake in middle of night, 3: minutes awake too early, 4: hours spent in bed, 5: total sleep time in hours, and 6: sleep efficiency) and Insomnia Severity Index (ISI) were taken as the primary and secondary outcomes respectively, measured at baseline, and after 3 months.

RESULTS

Five patients dropped out (verum: 2, control: 3). Intention to treat sample (n = 60) was analyzed. Trial arms were comparable at baseline. In the verum group, except sleep diary item 3 (P =  0.371), rest of the outcomes improved significantly (all P < 0.01). In the control group, there were significant improvements in diary item 6 and ISI score (P < 0.01) and just significant improvement in item 5 (P =  0.018). Group differences were significant for items 4, 5 and 6 (P < 0.01) and just significant (P =  0.014) for ISI score with moderate to large effect sizes; but non-significant (P > 0.01) for rest of the outcomes.

CONCLUSION

IH seemed to produce significantly better effect than placebo. Rigorous trials and independent replications are warranted.

A Systematic Review of Controlled Trials of Homeopathy in Bronchial Asthma

Homeopathy is a controversial form of complementary therapy, but is widely practised to treat asthma. The aim of this systematic review is to evaluate the controlled trials of homeopathy in bronchial asthma. Relevant trials published between Jan 1, 1981, and Dec 31, 2016, were considered. Substantive research articles, conference proceedings, and master and doctoral theses were eligible. Methodology was assessed by Jadad's scoring, internal validity by the Coch-rane tool, model validity by Mathie's criteria, and quality of individualization by Saha's criteria. Sixteen trials were eligible. The majority were positive, especially those testing complex formulations. Methodological quality was diverse; 8 trials had "high" risk of bias. Model validity and individualization quality were compromised. Due to both qualitative and quantitative inadequacies, proofs supporting individualized homeopathy remained inconclusive. The trials were positive (evidence level A), but inconsistent, and suffered from methodological heterogeneity, "high" to "uncertain" risk of bias, incomplete study reporting, inadequacy of independent replications, and small sample sizes.

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.

Efficacy of Arsenicum album 30cH in preventing febrile episodes following DPT-HepB-Polio vaccination - a randomized, double-blind, placebo-controlled clinical trial

BACKGROUND

Among the post-immunization adverse events, especially of Diphtheria-Pertusis-Tetanus (DPT), fever is a common systemic reaction. There is anecdotal support for the use of the homeopathic medicine Arsenicum album in preventing post-vaccination fever. The investigators intended to evaluate its efficacy in preventing febrile episodes following vaccination.

METHODS

In the community medicine out-patient of Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, West Bengal, India, between August 2014 and January 2017, a double-blind, randomized, placebo-controlled trial was conducted on 120 children (verum: 60, placebo: 60) who presented for the 2nd and 3rd dose of DPT-HepB-Polio vaccination and reported febrile episodes following the 1st dose. Intervention used was Arsenicum album 30cH 6 doses or placebo (indistinguishable from verum), thrice daily for two subsequent days. Parents were advised to report any event of febrile attacks within 48h of vaccination, either directly or over telephone.

RESULTS

The groups were comparable at baseline. Children reporting fever after the 2nd dose was 29.8% and 30.4% respectively for the homeopathy group and control group respectively [Relative Risk (RR)=1.008] with no significant difference (P=0.951) between groups. Again after the 3rd dose, children reporting fever were 31.5% and 28.3% respectively for the homeopathy group and control group respectively (RR=0.956) with no significant difference (P=0.719) between groups.

CONCLUSION

Empirically selected Arsenicum album 30cH could not produce differentiable effect from placebo in preventing febrile episodes following DPT-HepB-Polio vaccination. [Trial registration: CTRI/2017/02/007939].

Treatment of hemorrhoids with individualized homeopathy: An open observational pilot study

Aim:

Controversies and disagreement exist on conventional treatment strategies of hemorrhoids due to relapse, inefficacy, and complications. We intend to evaluate the role of individualized homeopathic treatment in hemorrhoids.

Materials and Methods:

In this prospective, open, observational trial, hemorrhoids patients were treated using five standardized scales measuring complaints severity and anoscopic score. It was conducted at two homeopathic hospitals in India, during from mid-July 2014 to mid-July 2015. Patients were intervened as per individualized homeopathic principles and followed up every month up to 6 months.

Results:

Total 73 were screened, 52 enrolled, 38 completed, 14 dropped out. Intention to treat population (n: = 52) was analyzed in the end. Statistically significant reductions of mean bleeding (month 3: −21.8, 95% confidence interval [CI]: −30.3, −13.3, P: < 0.00001, d = 0.787; month 6: −25.5, 95% CI −35.4, −15.6, P: < 0.00001, d = 0.775), pain (month 3: −21.3, 95% CI −28.6, −14.0, P: < 0.00001, d = 0.851; month 6: −27.6, 95% CI −35.6, −19.6, P: < 0.00001, d = 1.003), heaviness visual analog scales (VASs) (month 3: −8.1, 95% CI −13.9, −2.3, P: = 0.008, d = 0.609; month 6: −12.1, 95% CI −19.1, −5.1, P: = 0.001, d = 0.693), and anoscopic score (month 3: −0.4, 95% CI −0.6, −0.2, P: < 0.0001, d = 0.760; month 6: −0.5, 95% CI −0.7, −0.3, P: < 0.0001, d = 0.703) were achieved. Itching VASs reduced significantly only after 6 months (−8.1, 95% CI −14.6, −1.6, P: = 0.017, d = 0.586). No significant lowering of discharge VASs was achieved after 3 and 6 months.

Conclusion:

Under classical homeopathic treatment, hemorrhoids patients improved considerably in symptoms severity and anoscopic scores. However, being observational trial, our study cannot provide efficacy data. Controlled studies are required. Trial Reg. CTRI/2015/07/005958.
