Chinese herbal medicine for acute upper respiratory tract infections and reproductive safety: A systematic review

Shufeng Jiedu capsule for acute exacerbation of chronic obstructive pulmonary disease: a protocol of multicentre, randomised, double-blind, placebo-controlled trial

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) represents one of the leading causes of death worldwide. Published clinical trials suggest that the Chinese patent herbal medicine Shufeng Jiedu capsule (SFJD) is safe and may be effective for treating acute exacerbations of COPD (AECOPD). However, these effects have been reported with low or very low certainty evidence. This trial aims to evaluate the effectiveness and safety of SFJD for AECOPD.

METHODS AND ANALYSIS

This study is designed as a multicentre, randomised, double-blind, placebo-controlled trial. Three hundred patients with moderate or severe hospitalised AECOPD will be recruited in Beijing, Shanghai and Hefei. Participants will be randomly assigned to SFJD and usual care or placebo and usual care at a ratio of 1:1. SFJD and placebo will be administered orally four capsules three times daily for 7 consecutive days followed by an 8-week follow-up period. The primary outcome will be COPD symptom severity as measured by the EXAcerbation of Chronic Pulmonary Disease Tool score. Secondary outcomes include clinical symptoms, quality of life, length of hospital stay, a total dose of antibiotics, the frequency of recurrence of AECOPD, haematological biomarkers, death and adverse events. This study will answer the question of whether SFJD was safe to use and will improve symptoms in people with AECOPD, and will therefore reduce the necessity for antibiotics, the risk and duration of admission to hospital, and the risk of recurrence.

ETHICS AND DISSEMINATION

The ethics committee of the first affiliated hospital of Anhui Medical University, Beijing University of Chinese Medicine affiliated Dongzhimen hospital and fifth people's hospital of Shanghai Fudan University approved the study protocol. Informed written consent will be obtained from all the participants. The results of this trial will be disseminated at academic conferences and in peer-reviewed publications.

Chinese patent herbal medicine (Shufeng Jiedu capsule) for acute upper respiratory tract infections: A systematic review and meta-analysis

BACKGROUND

Shufeng Jiedu capsule has been widely used in China for acute upper respiratory tract infections (AURTIs). The aim of this study was to evaluate its effectiveness and safety for AURTIs.

METHODS

Randomized controlled trials comparing SFJD with conventional drug for patients with AURTIs were included. Eight databases were searched from their inceptions to February 2021. Data was synthesized using risk ration (RR) or mean difference (MD) with their 95% confidence interval (CI). The primary outcome was resolution time of typical symptoms.

RESULTS

Twenty-five RCTs involving 3410 patients were included. SFJD in combination with conventional drug was associated with; in common cold shortening the duration of fever (MD -1.54 days, 95% CI [-2.15,-0.92], I 2 = 80%, n = 385, 3 trials) and cough (MD -1.22 days, 95% CI [-1.52, -0.93]); in herpangina, shortening the duration of fever (MD -0.68 days, 95% CI [-1.15, -0.21], I2  = 68%, n = 140, 2 trials) and blistering (MD -0.99 days, 95% CI [-1.23, -0.76], n = 386, 3 trials); in acute tonsillitis and acute pharyngitis shortening the duration of fever (MD -1.13 days, 95% CI [-1.36, -0.90], I 2 = 33%, n = 688, 7 trials) and sore throat (MD -1.13 days, 95% CI [-1.40, -0.86], I 2 = 84.1%, n = 1194, 10 trials). SFJD also improving their cure rate with a range (1-5 days). No serious adverse events were reported.

CONCLUSION

Low certainty evidence suggests that SFJD appears to shorten the duration of symptoms in AURTIs, improve cure rate and seems safe for application. However, high quality placebo controlled trials are warranted to confirm its benefit.

Baicalein, Baicalin, and Wogonin: Protective Effects against Ischemia-Induced Neurodegeneration in the Brain and Retina

Ischemia is a common pathological condition present in many neurodegenerative diseases, including ischemic stroke, retinal vascular occlusion, diabetic retinopathy, and glaucoma, threatening the sight and lives of millions of people globally. Ischemia can trigger excessive oxidative stress, inflammation, and vascular dysfunction, leading to the disruption of tissue homeostasis and, ultimately, cell death. Current therapies are very limited and have a narrow time window for effective treatment. Thus, there is an urgent need to develop more effective therapeutic options for ischemia-induced neural injuries. With emerging reports on the pharmacological properties of natural flavonoids, these compounds present potent antioxidative, anti-inflammatory, and antiapoptotic agents for the treatment of ischemic insults. Three major active flavonoids, baicalein, baicalin, and wogonin, have been extracted from Scutellaria baicalensis Georgi (S. baicalensis); all of which are reported to have low cytotoxicity. They have been demonstrated to exert promising pharmacological capabilities in preventing cell and tissue damage. This review focuses on the therapeutic potentials of these flavonoids against ischemia-induced neurotoxicity and damage in the brain and retina. The bioactivity and bioavailability of baicalein, baicalin, and wogonin are also discussed. It is with hope that the therapeutic potential of these flavonoids can be utilized and developed as natural treatments for ischemia-induced injuries of the central nervous system (CNS).

Fever and Antipyretic Supported by Traditional Chinese Medicine: A Multi-Pathway Regulation

The coronavirus disease, 2019 (COVID-19), has spread rapidly around the world and become a major public health problem facing the world. Traditional Chinese medicine (TCM) has been fully committed to treat COVID-19 in China. It improved the clinical symptoms of patients and reduced the mortality rate. In light of the fever was identified as one of leading clinical features of COVID-19, this paper will first analyze the material basis of fever, including pyrogenic cytokines and a variety of the mediators of fever. Then the humoral and neural pathways of fever signal transmission will be described. The scattered evidences about fever recorded in recent years are connected in series. On this basis, the understanding of fever is further deepened from the aspects of pathology and physiology. Finally, combining with the chemical composition and pharmacological action of available TCM, we analyzed the mechanisms of TCMs to play the antipyretic effect through multiple ways. So as to further provide the basis for the research of antipyretic compound preparations of TCMs and explore the potential medicines for the prevention and treatment of COVID-19.

Herbal Medications Used to Treat Fever

Fever is a natural body defense and a common symptom of disease. Herbs have been used for thousands of years to treat fever. Many herbs have anti-inflammatory properties. Some are useful in reducing the release of cytokines and mediators of inflammation, whereas others work as natural aspirins to inhibit cyclooxygenase. In addition, herbs have known antipathogenic properties and can be effective in the treatment of infection from numerous microorganisms. Last, in traditional Chinese medicine, herbs are used to restore imbalances between the nonpathogenic and the pathogenic clearing interior heat and treating heat patterns in a variety of ways.

The usage of over-the-counter products by private insured patients in Germany - a claims data analysis with focus on complementary medicine

Background

An important contribution to well-being of human beings can be observed by the use of self-medication products that is reflected in the constantly growing volume of over-the-counter (OTC) drugs. The aim of the current study was to extend the measurement concept for OTCs by exploring the relevance of the peripheral assortment provided by the widely accepted framework of the Anatomical Therapeutical and Chemical (ATC) classification of the WHO.

Methods

The focus was on the prescriptions and drug-related receipts submitted by privately insured persons to 18 private health insurers (PHIs) in Germany from the year 2016. The age- and gender-specific average claims amount per risks of outpatient drug expenditure were used as weights to scale up the relative distributions of the item amounts. The ATC-classification defines the commodity groups and discriminates between the main and the peripheral assortment. A descriptive analysis assessed the OTC frequencies and sum scores of the product groups within the main and peripheral assortment whereby the study group explored and assessed the relevance of each category independently according to the OTCs and integrative medicines.

Results

The analysis included 22.1 Mio. packages from the main assortment and examined 10.1 Mio. packages from the peripheral assortment. The latter was examined thoroughly and the commodity groups “Pharmaceutical food products”, “Medicinal products for special therapy options” and particular “Hygiene and body care products” meet the defined requirements for OTCs relevant for integrative medicines. A high proportion of OTC products from the peripheral assortment was associated with the categories “medicinal products for special therapy options”. Homeopathy and anthroposophy present two special therapy options, which are relevant for the extended OTC measurement.

Conclusions

The analysis of OTC drugs is feasible when the main and the peripheral assortment is available and enable to integrate about 18% of all OTCs, which are neglected by the common ATC-based approach. The presented extended approach may help to identify potential users of OTCs or people in need of OTC use. In case of the highly disputed homeopathy and anthroposophy products, more research among interactions with prescriptions drugs (Rx), nutrition’s and other potentially harmful exposures is recommended.

Use of Mustard Seed Footbaths for Respiratory Tract Infections: A Pilot Study

Objective

Respiratory tract infections (RTIs) are the most commonly treated acute problems in general practice. Instead of treatment with antibiotics, therapies from the field of integrative medicine play an increasingly important role within the society. The aim of the study was to evaluate whether mustard footbaths improve the symptoms of patients with RTIs.

Methods

The study was designed as a pilot study and was carried out as an interventional trial with two points of measurement. Between November and December 2017, six practices were invited to participate. Two of them participated in the study. Patients were included who presented with an RTI at one of the involved primary care practices during February and April 2018. Participants in the intervention group used self-administered mustard seed powder footbaths at home once a day, to be repeated for six consecutive days. The improvement of symptoms was measured using the “Herdecke Warmth Perception Questionnaire” (HeWEF). A variance analysis for repeated measurements was performed to analyse differences between the intervention and control groups.

Results

In this pilot study, 103 patients were included in the intervention group and 36 patients were included in the control group. A comparison of the intervention and control group before the intervention started showed nearly no difference in their subjective perception of warmth measured by the HeWEF questionnaire. Participants of the intervention group who used mustard seed footbaths for six consecutive days showed an improvement in four of the five subscales of the HeWEF questionnaire.

Conclusions

This study could provide a first insight into a possible strategy to improve symptoms regarding RTI by using mustard seed footbaths.
