Cost-effectiveness analysis for SilAtro-5-90 adjuvant treatment in the management of recurrent tonsillitis, compared with usual care only.

PURPOSE: Antibiotics are one possible treatment for patients with recurrent acute throat infections (ATI), but effectiveness can be modest. In view of worries over antibiotic resistance, treatment pathways that reduce recurrence of ATI are essential from a public health perspective. Integrative treatment strategies can be an option but there is still a high demand to provide evidence of their cost effectiveness. METHODS: We constructed a 4-state Markov model to compare the cost-effectiveness of SilAtro-5-90 as adjuvant homeopathic therapy to care as usual with care as usual alone in reducing the recurrence of ATI for children and adults with suspected moderate recurrent tonsillitis. The analysis was performed from a societal perspective in Germany over a 2-year period. Results are reported separately for children < 12 and for individuals aged 12 and over. The model draws on evidence from a multi-centre randomised clinical trial that found this strategy effective in reducing recurrence of ATI. Costs in 2019 € and outcomes after 1 year are discounted at a rate of 3% per annum. RESULTS: For adults and adolescents aged 12 years and over, incremental cost per ATI averted in the adjuvant therapy group was €156.64. If individuals enter the model on average with a history of 3.33 previous ATIs, adjuvant therapy has both lower costs and better outcomes than care as usual. For children (< 12 years) adjuvant therapy had both lower costs and ATI than care as usual. The economic case is stronger if adjuvant treatment reduces surgical referral. At a hypothetical cost per ATI averted threshold of €1000 probabilistic sensitivity analysis suggests Silatro-5-90 has a 65% (adults) and 71% (children) chance of being cost-effective. CONCLUSION: Our results indicate the importance of considering homeopathy as adjuvant therapy in the treatment of ATIs in individuals with recurrent tonsillitis from a socio-economic perspective. Further evaluation should assess how differences in uptake and sustained use of homeopathic adjuvant therapy, as well as changing patterns of antibiotic prescribing, impact on cost effectiveness.

In vitro evaluation of the anti-pathogenic activity of Okoubaka aubrevillei on the human gastrointestinal tract.

BACKGROUND: Okoubaka aubrevillei is used in traditional West African medicine and in homeopathy for treatment and prevention of several gastrointestinal problems. The aim of this in vitro study was to evaluate the effect of repeated doses of two Okoubaka products (10 % ethanolic tincture, mother tincture (MT); 3rd decimal potency, 3X) on the microbial activity of physiological human colon microbiota using a Simulator of the Human Intestinal Microbial Ecosystem (SHIME®) and to investigate any preventive effect against infections with diarrhea-causing pathogens. METHODS: Upon inoculation with fecal microbiota from a healthy donor, 4 parallel proximal colon compartments of the SHIME were treated either with Okoubaka MT, Okoubaka 3X, ethanol control or blank control for 7 days. Using the Okoubaka-adapted microbial community from SHIME, 48 h challenge tests were performed with enterotoxigenic Escherichia coli (ETEC) and Salmonella enteritidis in 4 different doses (103-108 colony forming units as typical in vivo infectious doses). Pathogen concentrations, short-chain fatty acids (SCFAs) and branched SCFA production were measured in triplicate at 0, 24 and 48 h. RESULTS: In the challenge tests, both Okoubaka products were able to restrict the colonization of ETEC and Salmonella at 3 of the 4 pathogen doses (except the highest doses), with a stronger anti-pathogenic effect for MT, which included a reduction of 2.0 log-units of ETEC (p < 0.0001) and 1.1 log-units of Salmonella (p < 0.0001). Total SCFA levels remained unaffected, but butyrate increased during the first 24 h (p < 0.0001 for ETEC), accompanied by decreased acetate production. CONCLUSION: We observed in vitro a systemic activating effect of Okoubaka on intestinal microbiome resistance, which resulted in an anti-pathogenic effect, especially against ETEC. We hypothesize that the mode of action in vivo is also based on systemic regulative effects.

Effectiveness of a homeopathic complex medicine in infantile colic: A randomized multicenter study.

OBJECTIVES: Infantile colic is a common benign disease occurring in early infancy that may have a great impact on family life. In the present study, the effectiveness and safety of the complex homeopathic medicine Enterokind was compared with Simethicone for treating infantile colic. DESIGN AND SETTING: Current data were drawn from a prospective, multicenter, randomized, open-label, controlled clinical trial that was conducted in 2009 in 3 Russian outpatient clinics. Children received either Enterokind (Chamomilla D6, Cina D6, Colocynthis D6, Lac defloratum D6 and Magnesium chloratum D6) or Simethicone. Data from infants ≤ 6 months with infantile colic are presented here. MAIN OUTCOME MEASURES: The main outcomes assessments were the change of total complaints score (maximum 17 points) and total objective symptoms score (maximum 22 points) after 10 days of treatment. RESULTS: Data from 125 infants ≤ 6 months with infantile colic were analyzed. The differences in total complaints and objective symptoms scores between baseline and day 10, estimated from the ANCOVA model, were found to be highly significant (p < 0.0001; ITT) in favor of Enterokind, both for complaints (Δ=-2.38; 95% confidence interval (CI): [-2.87; -1.89]) and for objective symptoms (Δ=-2.07; 95% CI: [-2.65; -1.49]). 1 adverse event (AE), vomiting, occurred under Enterokind and was rated to be unlikely related to it; 4 AEs occurred under Simethicone. All AEs were non-serious. CONCLUSIONS: The current study indicates that Enterokind is an effective and safe homeopathic treatment for functional intestinal colic in infants ≤ 6 months.

Effectiveness of an add-on treatment with the homeopathic medication SilAtro-5-90 in recurrent tonsillitis: An international, pragmatic, randomized, controlled clinical trial.

OBJECTIVE: To investigate the effectiveness and safety of the homeopathic product SilAtro-5-90 in recurrent tonsillitis. METHODS: In this international, pragmatic, controlled clinical trial, 256 patients (6-60 years) with moderate recurrent tonsillitis were randomized to receive either SilAtro-5-90 in addition to standard symptomatic treatment, or to receive standard treatment only. The primary outcome was the mean time period between consecutive acute throat infections (ATI) within 1 year (analyzed via repeated events analysis). RESULTS: During the evaluation year, the risk of getting an ATI was significantly lower (hazard ratio: 0.45, proportional means model, p = 0.0002, ITT) with SilAtro-5-90 compared to control. Tonsillitis-specific symptoms were significantly reduced (p < 0.0001, ITT) and the need of antibiotics to treat acute throat infections (p = 0.0008; ITT) decreased. 3 non-serious adverse drug reactions were reported for SilAtro-5-90. CONCLUSIONS: An integrative treatment approach where SilAtro-5-90 is given alongside mainstream symptomatic treatment may bring therapeutic benefit to patients suffering from recurrent tonsillitis.

The Effectiveness and Safety of a Homeopathic Medicinal Product in Pediatric Upper Respiratory Tract Infections With Fever: A Randomized Controlled Trial.

We investigated the clinical effectiveness of a homeopathic add-on therapy in a pediatric subpopulation with upper respiratory tract infections (URTI) in a randomized, controlled, multinational clinical trial. Patients received either on-demand symptomatic standard treatment (ST-group) or the same ST plus a homeopathic medication (Influcid; IFC-group) for 7 days. Outcome assessment was based on symptom and fever resolution and the Wisconsin Upper Respiratory Symptom Survey-21 (WURSS-21). A total of 261 pediatric (<12 years) patients (130 IFC-group; 131 ST-group) were recruited in Germany and the Ukraine. The IFC-group used less symptomatic medication, symptoms resolved significantly earlier (P = .0001), had higher proportions of fever-free children from day 3 onwards, and the WURSS-assessed global disease severity was significantly less (P < .0001) during the entire URTI episode. One adverse event (vomiting) was possibly related to IFC. IFC as add-on treatment in pediatric URTI reduced global disease severity, shortened symptom resolution, and was safe in use.

A Comparative Randomized Controlled Clinical Trial on the Effectiveness, Safety, and Tolerability of a Homeopathic Medicinal Product in Children with Sleep Disorders and Restlessness.

A prospective, multicenter, randomized, open-label, controlled clinical trial was performed to evaluate the effectiveness and safety of the homeopathic product ZinCyp-3-02 in children with sleep disorders for ≥ one month compared to glycine. Children ≤ six years old received either ZinCyp-3-02 (N = 89) or comparator glycine (N = 90). After treatment for 28 days, total sleep-disorder-associated complaints severity scores decreased in both groups from median 7.0 (out of maximum 11.0) points to 2.0 (ZinCyp-3-02) and 4.0 (glycine) points, respectively, with overall higher odds of showing improvement for ZinCyp-3-02 (odds ratio: 4.45 (95% CI: 2.77-7.14), p < 0.0001, POM overall treatment related effect). Absence of individual complaints (time to sleep onset, difficulties maintaining sleep, sleep duration, troubled sleep (somniloquism), physical inactivity after awakening, restlessness for unknown reason, and sleep disorders frequency) at study end were significantly higher with ZinCyp-3-02 (all p values < 0.05). More children with ZinCyp-3-02 were totally free of complaints (p = 0.0258). Treatment effectiveness (p < 0.0001) and satisfaction assessments (p < 0.0001) were more favorable for ZinCyp-3-02. Few nonserious adverse drug reactions were reported (ZinCyp-3-02: N = 2, glycine: N = 1) and both treatments were well tolerated. Treatment with the homeopathic product ZinCyp-3-02 was found to be safe and superior to the comparator glycine in the treatment of sleep disorders in children.

Effectiveness, safety and tolerability of a complex homeopathic medicinal product in the prevention of recurrent acute upper respiratory tract infections in children: a multicenter, open, comparative, randomized, controlled clinical trial.

BACKGROUND: The present study was initiated to investigate the effectiveness, safety and tolerability of complex homeopathic CalSuli-4-02 tablets on prevention of recurrent acute upper respiratory tract infections (URTIs) in children, in comparison to another complex homeopathic product. METHODS: The study was designed as a prospective, multicenter, randomized, open, clinical trial with two parallel treatment groups at four outpatient pediatric clinics in Russia. Children aged ≤ 6 years with susceptibility to acute URTIs (≥ three occasions during the last 6 months) were randomized to receive either CalSuli-4-02 or a comparator homeopathic product (control group) for 3 weeks. Primary outcome was the frequency of acute URTIs after 3 and 6 months post-treatment follow-up. Secondary endpoints were changes in complaints and symptoms (total and individual scores), treatment satisfaction, antibiotic use, safety and tolerability. RESULTS: The intention-to-treat analysis involved 200 children (CalSuli-4-02: N = 99, CONTROL: N = 101). In both treatment groups, the median number of acute URTIs was one for 3 months and two, respectively, for the full 6 months post-treatment (Relative Risk: 0.86 (95 %-CI: 0.72-1.03), p = 0.1099). Seasons had no influence on the outcome. At the end of study, CalSuli-4-02 had overall higher odds of getting lower complaints severity total score (Odds ratio: 1.99 (95 %-CI: 1.31-3.02), p = 0.0012) and showing symptom improvement (Odds ratio: 1.93 (95 %-CI: 1.25-3.00), p = 0.0033). Specifically, the complaint "appetite disorder" and the symptom "child's activities" significantly improved more in the CalSuli-4-02 group (p = 0.0135 and p = 0.0063, respectively). Antibiotic use was decreased in both treatment groups at the study end. Overall assessment for satisfaction with and tolerability of treatment was higher with CalSuli-4-02. A low number of non-serious adverse drug reactions was reported (CalSuli-4-02: N = 4, CONTROL: N = 1). CONCLUSIONS: Both complex homeopathic products led to a comparable reduction of URTIs. In the CalSuli-4-02 group, significantly less URTI-related complaints and symptoms and higher treatment satisfaction and tolerability were detected. The observation that the use of antibiotics was reduced upon treatment with the complex homeopathic medications, without the occurrence of complications, is interesting and warrants further investigations on the potential of CalSuli-4-02 as an antibiotic sparing option.

A Homeopathic Combination Preparation in the Treatment of Feverish Upper Respiratory Tract Infections: An International Randomized Controlled Trial.

BACKGROUND: Upper respiratory tract infections (URTI) are very common and associated with considerable healthcare costs. We evaluated the clinical benefit of a homeopathic add-on therapy. PATIENTS AND METHODS: In this randomized controlled multinational clinical trial, patients (age range 1-65 years) with feverish URTI received either on-demand symptomatic standard treatment (ST group: paracetamol, ambroxol, and/or oxymetazoline), or homeopathic medication (IFC group: Influcid®) for 7 days plus the same on-demand standard treatment. URTI symptoms were assessed using the Wisconsin Upper Respiratory Symptom Survey-21. Response at day 4, defined as absence of fever and absence or very mild degree of URTI symptoms, was the primary outcome measure. RESULTS: 523 patients (265 IFC group, 258 ST group) were randomized in 12 Ukrainian and 10 German centers. The responder rate on day 4 was 15.4% in the IFC group and 6.7% in the ST group (x0394;IFC-ST = 8.7%, 95% confidence interval 2.9-14.5%). The IFC group used less symptomatic medication, and symptoms were alleviated 1-2 days earlier. 3 and 8 adverse events (AEs) in the IFC and ST group, respectively, were assessed as possibly treatment-related; 2 out of the 3 AEs in the IFC group were possibly related to symptomatic therapy, 1 (vomiting) to IFC treatment. CONCLUSION: The homeopathic treatment shortened URTI duration, reduced the use of symptomatic medication, and was well tolerated.

The sensitivity and specificity of p16(INK4a) cytology vs HPV testing for detecting high-grade cervical disease in the triage of ASC-US and LSIL pap cytology results.

We analyzed the performance of p16(INK4a) immunocytochemistry on a series of 810 retrospectively collected atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL) cases with available biopsy follow-up data, including 94 cases of cervical intraepithelial neoplasia (CIN) 2 and 128 cases of CIN 3. Human papillomavirus (HPV) testing was performed from the same residual liquid-based cytologic specimen, and results for both tests were correlated with histologic follow-up data. Sensitivity values for high-grade CIN (HGCIN) confirmed on biopsy within 6 months were 92.6% (ASC-US) and 92.2% (LSIL) for cytotechnologists' reviews of p16 cytology and 90.1% (ASC-US) and 95.7% (LSIL) for HPV testing. Sensitivity rates of initial pathologists' reviews were slightly lower, 76.4% to 80.1%, with levels comparable to cytotechnologists' results after adjudication. The specificity of p16 cytology for HGCIN detection was significantly higher than for HPV testing for cytotechnologists and pathologists: 63.2% to 71.1% (p16 cytology) vs 37.8% for HPV in ASC-US (P < .001) and 37.3% to 53.3% (p16 cytology) vs 18.5% for HPV in LSIL (P < .001). This evaluation of the diagnostic performance of p16 cytology confirms the potential of this stain for the efficient triage of ASC-US and LSIL cytologic results.
