This study sought to investigate the antihyperuricemia efficacy and safety of DKB114 (a mixture of Chrysanthemum indicum Linn flower extract and Cinnamomum cassia extract) to evaluate its potential as a dietary supplement ingredient. This clinical trial was a randomized, 12-week, double-blind, placebo-controlled study. A total of 80 subjects (40 subjects with an intake of DKB114 and 40 subjects with that of placebo) who had asymptomatic hyperuricemia (7.0–9.0 mg/dL with serum uric acid) was randomly assigned. No significant difference between the DKB114 and placebo groups was observed in the amount of uric acid in serum after six weeks of intake. However, after 12 weeks of intake, the uric acid level in serum of subjects in the DKB114 group decreased by 0.58 ± 0.86 mg/dL and was 7.37 ± 0.92 mg/dL, whereas that in the placebo group decreased by 0.02 ± 0.93 mg/dL and was 7.67 ± 0.89 mg/dL, a significant difference (p = 0.0229). In the analysis of C-reactive protein (CRP) change, after 12 weeks of administration, the DKB114 group showed an increase of 0.05 ± 0.27 mg/dL (p = 0.3187), while the placebo group showed an increase of 0.10 ± 0.21 mg/dL (p = 0.0324), a statistically significant difference (p = 0.0443). In the analysis of amount of change in apoprotein B, after 12 weeks of administration, the DKB114 group decreased by 4.75 ± 16.69 mg/dL (p = 0.1175), and the placebo group increased by 3.13 ± 12.64 mg/dL (p = 0.2187), a statistically significant difference between the administration groups (p = 0.0189). In the clinical pathology test, vital signs and weight measurement, and electrocardiogram test conducted for safety evaluation, no clinically significant difference was found between the ingestion groups, confirming the safety of DKB114. Therefore, it may have potential as a treatment for hyperuricemia and gout. We suggest that DKB114 as a beneficial and safe food ingredient for individuals with high serum uric acid.

Homoeopathic potencies of arnica have been used for many years to aid postoperative recovery. The effects of arnica C30 on pain and postoperative recovery after total abdominal hysterectomy were evaluated in a double-blind, randomized, controlled study. Of 93 women entered into the study, 20 did not complete protocol treatment: nine were excluded because they failed to comply with the protocol, nine had their operations cancelled or changed within 24 h and two had to be withdrawn because of the recurrence of previously chronic painful conditions. Those who did not complete protocol treatment were equally divided between the arnica (nine patients) and placebo groups (11 patients). 73 patients completed the study, of whom 35 received placebo and 38 received arnica C30. The placebo group had a greater median age and the arnica group had slightly longer operations; nevertheless, no significant difference between the two groups could be demonstrated. We conclude that arnica in homoeopathic potency had no effect on postoperative recovery in the context of our study.

Objectives. We aimed at evaluating both the efficacy and safety of TJ-54 (Yokukansan) in patients with treatment-resistant schizophrenia. This randomized, multicenter, double-blind, placebo-controlled study was conducted.Methods. One hundred and twenty antipsychotic-treated inpatients were included. Patients were randomized to adjuvant treatment with TJ-54 or placebo. During a 4-week follow-up, psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS).Results. TJ-54 showed a tendency of being superior to placebo in reduction total, positive, and general PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant in both per-protocol set (PPS) and intention-to-treat (ITT). However, in PPS analysis, compared to the placebo group, the TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores for lack of spontaneity and flow of conversation (TJ-54:−0.23±0.08; placebo:−0.03±0.08,P<0.018), tension (TJ-54:−0.42±0.09; placebo:−0.18±0.09,P<0.045), and poor impulse control (TJ-54:−0.39±0.10; placebo:−0.07±0.10,P<0.037).Conclusions. The results of the present study indicate that TJ-54 showed a tendency of being superior to placebo in reduction PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant. However, compared to the placebo group, TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores.

This multicenter, double-blind, placebo-controlled clinical trial was conducted to obtain additional data on the efficacy and safety of Anaferon for the treatment of acute respiratory viral infections (ARVI) during seasonal increase in their incidence (RCT of the Ministry of Health of Russia No 356 dated 24.07.2018; ClinicalTrials.gov Identifier: NCT03707912). Patients and methods. Between October 2018 and March 2019, a total of 204 patients aged 18 to 70 years with ARVI symptoms were included in this study within the first 24 hours of symptom onset. Patients were randomized into 2 groups: 104 individuals received oral Anaferon (should be kept in the mouth until completely dissolved and without food) according to the following scheme: 1 tablet every 30 minutes during the first 2 hours; then 3 more doses at regular intervals during the first day; then 1 tablet 3 times a day on days 2–5; 100 individuals received placebo according to the same scheme. The primary endpoint was time to resolution of symptoms of clinically diagnosed and/or PCR (polymerase chain reaction) – confirmed ARVI. Addithional endpoints included: time to resolution of symptoms of ARVI confirmed by PCR; proportion of patients with resolution of symptoms of clinically diagnosed and/or PCR-confirmed ARVI and separately PCR-confirmed ARVI; severity of clinically diagnosed and/or PCR-confirmed ARVI (assessed by ‘area under the curve’ for the total severity index); the number of antipyretic doses taken according to indications on days 1–3 of treatment (checked in the patient's diary); proportion of patients who required antibiotic treatment on days 4–7 of follow-up. To assess safety, we analyzed the incidence and type of adverse events (AEs), their severity, association with drug use, and treatment outcome. The following statistical methods were used: Fisher's exact test, Cochran–Mantel–Haenszel test, Wilcoxon test, and repeated measures ANOVA, PROC MIXED. Results. A total of 203 patients were included in the intention-to-treat (ITT) and per protocol (РР) analysis: 103 [95] individuals in the Anaferon arm and 100 [93] individuals in the Placebo arm. Patients receiving Anaferon had significantly shorter time to resolution of all ARVI symptoms than patients receiving placebo: 4.1 ± 1.6 days vs 4.5 ± 1.5 days (p = 0.032). The disease was on average 1 day shorter in patients from the experimental group compared to controls: 3.6 ± 1.5 days vs 4.6 ± 1.5 days (p = 0.007). The proportion of patients who had resolution of symptoms of clinically diagnosed and/or PCR-confirmed ARVI was significantly higher in the Anaferon arm compared to Placebo arm (p = 0.0012). Among patients with PCR-verified ARVI, treatment with Anaferon resulted in twice as frequent recovery as in the control group on day 4 (53.7% vs 26.3%) and day 7 (70.7% vs 36.8%). In the Anaferon arm, we observed shorter disease duration and higher proportion of patients recovered compared to the Placebo arm; however, patients in both groups had a similar need for antipyretic drugs on days 1–3 of treatment, as well as for antibiotic therapy. The incidence of AEs in the Anaferon and Placebo groups did not vary significantly. No AEs with a reliable association with Anaferon were registered. Conclusion. Our findings suggest high efficacy and safety of Anaferon in patients with ARVI. The best results were obtained in patients with PCR-verified diagnosis, which can be attributed to the involvement of the interferon system in the action of the drug. The results of this RCT confirm the data obtained in previous studies and long-term clinical experience of using Anaferon.

Background and Aim: Mild cognitive impairment (MCI) is characterized by declined cognitive function greater than that expected for a person’s age. The clinical significance of this condition is its possible progression to dementia. MLC601 is a natural neuroprotective medication that has shown promising effects in Alzheimer disease. Accordingly, we conducted this randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of MLC601 in MCI patients. Methods: Seventy-two patients with a diagnosis of MCI were recruited. The included participants were randomly assigned to groups to receive either MLC601 or placebo. An evaluation of global cognitive function was performed at baseline as well as at 3-month and 6-month follow-up visits. Global cognitive function was assessed by Mini-Mental State Examination (MMSE) and Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-cog) scores. Efficacy was evaluated by comparing global function scores between the 2 groups during the study period. Safety assessment included adverse events (AEs) and abnormal laboratory results. Results: Seventy patients completed the study, 34 in the MLC601 group and 36 in the placebo group. The mean changes (±SD) in cognition scores over 6 months in the MLC601 group were –2.26 (±3.42) for the MMSE and 3.82 (±6.16) for the ADAS-cog; in the placebo group, they were –2.66 (±3.43) for the MMSE and 4.41 (±6.66) for the ADAS-cog. The cognition changes based on both MMSE and ADAS-cog scores were statistically significant between the placebo and the MLC601 group (p < 0.001). Only 5 patients (14.7%) reported minor AEs in the MLC601 group, the most commonly reported of which were gastrointestinal, none of them leading to patient withdrawal. Conclusion: MLC601 has shown promising efficacy and acceptable AEs in MCI patients.

ABSTRACT Background With the frequent use of video display units, eye fatigue is becoming more common globally. An alternative nutritional strategy is needed to prevent the aggravation of eye fatigue symptoms. Objectives The objective was to evaluate the protective effect of a novel botanical combination of lutein ester, zeaxanthin, and extracts of blackcurrant, chrysanthemum, and goji berry on adults with eye fatigue in a randomized, double-blind, placebo-controlled clinical trial. Methods We randomly allocated 360 participants into 4 groups to receive placebo and 3 doses of our formula (chewable tablets, containing 6 mg, 10 mg, or 14 mg of lutein) once daily for 90 d. Each participant had 3 visits at baseline (V1), 45 d (V2), and 90 d (V3) during the study. Results Intervention with the formula improved individual scores of eye fatigue symptoms, including eye soreness, blurred vision, dry eye, foreign body sensation, and tearing. Compared with placebo, the formula at all 3 doses significantly decreased the total score of eye fatigue symptoms and increased the visuognosis persistence time at both V2 and V3. According to the Schirmer test, both 10-mg and 14-mg lutein formula groups had improved tear secretion at V3 compared with the placebo. The keratography results indicated that the first tear break-up time, average tear break-up time, and tear meniscus height were significantly increased after formula intervention. The formula at all 3 doses significantly increased the macular pigment optical density at V2 and V3 compared with the placebo, whereas optical coherence tomography showed no significant difference in retinal thickness and retinal volume across all groups at both visits. Conclusions Our botanical formula improves eye fatigue, dry eye, and macular function without changing the retinal structure, and thus it could serve as an effective nutritional strategy in improving eye fatigue without causing serious side effects.

Background To determine the efficacy of low-dose, immediate-release tacrolimus in patients with myasthenia gravis (MG) with inadequate response to glucocorticoid therapy in a randomized, double-blind, placebo-controlled study. Methods Eligible patients had inadequate response to glucocorticoids (GCs) after ⩾6 weeks of treatment with prednisone ⩾0.75 mg/kg/day or 60–100 mg/day. Patients were randomized to receive 3 mg tacrolimus or placebo daily (orally) for 24 weeks. Concomitant glucocorticoids and pyridostigmine were allowed. Patients continued GC therapy from weeks 1–4; from week 5, the dose was decreased at the discretion of the investigator. The primary efficacy outcome measure was a reduction, relative to baseline, in quantitative myasthenia gravis (QMG) score assessed using a generalized linear model; supportive analyses used alternative models. Results Of 138 patients screened, 83 [tacrolimus ( n = 45); placebo ( n = 38)] were enrolled and treated. The change in adjusted mean QMG score from baseline to week 24 was −4.9 for tacrolimus and −3.3 for placebo (least squares mean difference: –1.7, 95% confidence interval: −3.5, −0.1; p = 0.067). A post-hoc analysis demonstrated a statistically significant difference for QMG score reduction of ⩾4 points in the tacrolimus group (68.2%) versus the placebo group (44.7%; p = 0.044). Adverse event profiles were similar between treatment groups. Conclusions Tacrolimus 3 mg treatment for patients with MG and inadequate response to GCs did not demonstrate a statistically significant improvement in the primary endpoint versus placebo over 24 weeks; however, a post-hoc analysis demonstrated a statistically significant difference for QMG score reduction of ⩾4 points in the tacrolimus group versus the placebo group. This study was limited by the low number of patients, the absence of testing for acetylcholine receptor antibody and the absence of stratification by disease duration (which led to a disparity between the two groups).

Abstract Background Mild cognitive impairment (MCI) is considered an intermediate phase between normal aging and dementia. As the majority of cases of amnestic MCI (aMCI) progress to Alzheimer’s disease (AD), it is considered the prodromal stage of AD, and a treatment target for prevention of further cognitive decline. However, no medications have been shown to have symptomatic or preventive benefits in MCI. Kami-guibi-tang (KGT) is a traditional herbal formula used in Korean medicine to treat amnesia, which is reported to increase acetylcholine levels via activation of choline acetyltransferase. The objective of this study was to evaluate the efficacy and safety of KGT in patients with aMCI. Methods This study was designed as a single-center, randomized, double-blind, placebo-controlled pilot study. Participants diagnosed with aMCI were randomized to receive either KGT or placebo granules for 24 weeks. The efficacy measure was a change in the Seoul Neuropsychological Screening Battery (SNSB) score. The safety measures included the occurrence of adverse events and abnormalities in vital signs and blood chemistry, electrocardiogram (ECG), and brain magnetic resonance imaging (MRI) findings. Results A total of 16 patients in the KGT group and 14 patients in the placebo group were investigated in the study. The mean score of Clinical Dementia Rating-Sum of Boxes (CDR-SB) significantly improved from 1.53 (0.64) points to 1.13 (0.62) points in the KGT group (p = 0.010), whereas it worsened from 1.61 (0.88) points to 1.75 (0.94) points in the placebo group. There was a significant difference in the CDR-SB scores between the two groups after the intervention (p = 0.045). The total SNSB-D scores and the scores in the memory domain after the treatment were significantly higher than the baseline values in the KGT group, but not in the placebo group. The frequency of adverse events was not significantly different between the two groups, and there were no abnormalities in vital signs or blood test, ECG, and brain MRI findings after the intervention. Conclusions KGT may provide a safe and effective treatment option for patients with aMCI. Further studies with a larger sample size are needed to validate the findings.
