Safely Using TCM Herbs： Adverse Reactions and Precautions

Although most people believe that herbal remedies are relatively safe to use, some are toxic or possess adverse reactions, especially when used incorrectly.Commonly used TCM herbs with known adverse reactions, as well as the most toxic herbs in the Pharmacopoeia of People’s Republic of China are listed as follows:

Clinical observation of Shenmai injection in the treatment for adverse reactions of chemotherapy on advanced non-small cell lung cancer

Objective: To observe the efficacy of Shenmai injection in the treatment for adverse reactions of chemotherapy on advanced non-small cell lung cancer (NSCLC). Methods: 45 NSCLC patients with stages IIIb-IV were randomly divided into two groups: the treatment group (treated by chemotherapy combined with Shenmai injection) and the control group (treated by chemotherapy only). The efficacy of the two groups was evaluated after 3 cycles of treatment. Results: There was no significant difference between the two groups in the recent curative effects (P > 0.05), while there were significant differences between them in Karnofsky score and weight (P < 0.05). The treatment group was better than the control group in preventing leucopenia and decreased hemoglobin, and significant differences were found between them (P < 0.05). The incidence of thrombocytopenia, nausea and vomiting, hepatic and renal dysfunction in the treatment group was lower than that in the control group, but no significant differences were found between them (P > 0.05). Conclusion: Shenmai injection would not influence the efficacy of chemotherapy on advanced NSCLC patients, while it could improve the quality of life, increase the body weight of patients, alleviate adverse reactions of chemotherapy as myelosuppression so as to improve the tolerance of organism to chemotherapy.

Protective Effect of Oral Steroid Premedication: Adverse Reactions to Nonionic Iodine Contrast Media for Computed Tomography

This study aimed to investigate the protective effect of oral steroid premedication in terms of adverse reactions to non-ionic contrast media. We investigated the incidence of adverse reactions among patients who underwent contrast-enhanced computed tomography. Patients in the premedication group took 30 mg of prednisolone orally the night before and on the morning of the scheduled computed tomography. Sixty-five patients received the same contrast media. Among them, 56 took prednisolone orally prior to the procedure (premedication without change of contrast media group) and nine without premedication (no premedication and no change of contrast media group). In total, 379 patients received different contrast media. Among them, 340 took prednisolone orally (premedication with change of contrast media group), while 39 did not take the premedication (no premedication with change of contrast media group). The adverse reaction rates in the premedication with change of contrast media and no premedication with change of contrast media groups were 1.8% (6/340 cases) and 2.6% (1/39 cases) (P = 0.54), respectively. The incidence of adverse reaction after the administration of non-ionic iodinated contrast media did not differ significantly based on whether an oral steroid was administered prior to compute tomography. Our evaluation is limited due to the small sample size of the contrast media-changed group. However, even if premedication with steroids is effective, it may only result in an adverse reaction reduction rate of ≤3%.

Attention and Intervention of Oncologists on Oxaliplatin-induced Adverse Reactions in China' Mainland:A Cross-sectional Internet-based Survey

Objective This cross-sectional study aimed to investigate the current attention and intervention of oncologists on oxaliplatin(OXA)-induced adverse reactions(ADRs).Methods In 31 provinces or administrative regions across China,401 oncologists were surveyed through a self-designed questionnaire.The survey queried the basic information of respondents,clinical use of OXA,OXA-induced ADRs,and relative interventions.Chi-square tests and multiple logistic regression were used to explore the sociodemographic factors influencing the safety perception of OXA and the relevant interventions.Results The survey showed that the age of respondents was mainly distributed between 30 and 40 years and the working period for most oncologists was no more than 5 years.Oncologists with long working years were more willing to conduct patient education and inquire about ADRs than those with short working years.The rate of ADRs reported by oncologists with intermediate professional titles was significantly higher than that reported by oncologists with junior and senior professional titles.Conclusion Our findings indicate that oncologists in China's Mainland are concerned about OXA-induced ADRs,but the reporting of ADRs still needs to be strengthened.Therefore,training and educational programs are urgently needed to improve the risk management of OXA-induced ADRs among oncologists.

Incidence of adverse reactions to COVID-19 vaccination:A meta-analysis of randomized controlled trials

Objective:To systematically evaluate the incidence of adverse reactions to coronavirus disease 2019(COVID-19)vaccination.Methods:We systematically searched PubMed,Embase,The Cochrane Library,Web of Science,CNKI,WanFang Data,and VIP Database from the inception of each database to August 31,2021.Randomized controlled clinical trials(RCTs)on the safety of different types of COVID-19 vaccines were retrieved and analyzed.A random or fixed-effects model was used with an odds ratio as the effect size.The quality of each reference was evaluated.The incidence of the adverse reactions of the placebo group and the vaccination group was compared.Heterogeneity and publication bias were taken care of by meta-regression and sub-group analyses.Results:A total of 13 articles were included,with 81287 subjects.Compared with the placebo group,the vaccination group showed a higher combined risk ratio(RR)of total adverse reactions(RR=1.67,95%CI:1.46-1.91,P<0.01),local adverse reactions(RR=2.86,95%CI:2.11-3.87,P<0.01),systemic adverse reactions(RR=1.25,95%CI:0.92-1.72,P=0.16),pain(RR=2.55,95%CI:1.75-3.70,P<0.01),swelling(RR=4.16,95%CI:1.71-10.17,P=0.002),fever(RR=2.34,95%CI:1.84-2.97,P<0.01),fatigue(RR=1.36,95%CI:1.32-1.41,P<0.01)and headache(RR=1.22,95%CI:1.18-1.26,P<0.01).The subgroup analysis showed the incidence of adverse reactions of the vaccination group after injection of the three COVID-19 vaccines(inactivated viral vaccines,mRNA vaccines and adenovirus vector vaccines)was higher than that of the placebo group,and the difference between the placebo group and the vaccination group in the mRNA vaccine subgroup and the adenovirus vector vaccine subgroup was statistically significant(P<0.01).The incidence of adverse reactions after injection of COVID-19 vaccine in subgroups of different ages was significantly higher than that in the placebo group(P<0.01).Conclusions:COVID-19 vaccines have a good safety,among which adenovirus vector vaccine has the highest incidence of adverse reactions.Both adolescents and adults vaccinated with novel coronavirus vaccine have a certain proportion of adverse reactions,but the symptoms are mild and can be relieved by themselves.Our meta-analysis can help boost global awareness of vaccine safety,promote mass vaccination,help build regional and global immune barriers and effectively curb the recurrency of COVID-19.

Safely Using TCM Herbs: Adverse Reaction and Precautions (Continued)

Chan su (Venenum Bufonis,蟾酥)Its main active and toxic constituent is bufotoxin, which has a function similar to digitalis glycosides.Adverse reactions and toxicity: Chan su, althoughit is used in patent preparations, is traditionally known for its toxicity and is seldom used in decoctions. Toxicity is often due to over dosage of the patents, such as Liushenwan (六神丸) and Houzhengwan (喉症丸). After administration

Jinlong capsule decreases adverse reactions after transcatheter arterial chemoembolization(TACE) in patients with hepatocellular carcinoma

Objective The aim of this study was to analyze whether Jinlong capsule could decrease adverse reactions after transcatheter arterial chemoembolization(TACE) in patients with hepatocellular carcinoma. Methods Eighty-two patients with hepatocellular carcinoma were randomly divided into the control group and experimental group. On the first day after TACE, the experimental group started receiving four Jinlong capsules orally three times daily, whereas the control group did not receive the treatment.Results The incidences of erythropenia and thrombocytopenia in the experimental group was lower than those in the control group(P = 0.040 and 0.033, respectively). The differences in serum levels of aminotransferase, albumin, potassium, and sodium between the two groups were significant(P = 0.034, 0.034, 0.013, and 0.044, respectively). The mean durations of stomachache and abdominal distension in the experimental group was significantly shorter than those in the control group(P = 0.004 and 0.021, respectively). However, there were no significant differences in the incidences of nausea, fever, and vomiting between the two groups(P = 0.490, 0.495, and 0.585, respectively). Conclusion The reduction in the incidence rate and duration of partial adverse reactions after TACE was observed in hepatocellular carcinoma patients treated with Jinlong capsule compared to untreated patients, suggesting possible beneficial effects exerted by Jinlong capsule on the reduction of TACE-induced liver damage, thereby improving liver function and, consequently, the quality of life.

A Case of Adverse Reaction to Booster Dose of COVID-19 Vaccination: Could D-Dimer Elevation Suggest Increased Clotting Risk?

We report the clinical case of a 40-year-old Italian woman, who soon after her booster vaccination with mRNA-1273 after the two previous vaccinations with BNT162b2, developed severe headache, high fever, and Musculo-skeletal pain. She went to the emergency department, where computerized tomography (CT) scans of chest and brain were performed, resulting in both negative for pathologic findings. On the contrary, white blood count was strongly lowered and D-dimer severely elevated. She improved after treatment with enoxaparin and the blood analyses returned in the normal range after ten days. This case supports the hypothesis that COVID-19 vaccines could increase blood clotting in some predisposed subjects. Therefore, we believe that robust and well-designed clinical trials, considering the evaluation of D-dimer levels, should be performed to eliminate any doubts on this issue.

Analysis of the adverse reactions of atezolizumab: A real-world study based on FAERS database

Objective In this study,we aimed to determine the incidence of adverse drug reactions(ADRs)of atezolizumab,identify ADR signals that are significantly related to atezolizumab,and provide a reference for the rational use of atezolizumab in the clinic through the statistical analysis of its adverse drug events(ADEs)reported in the American Food and Drug Administration(FDA)Adverse Event Reporting System(FAERS)database.Methods In total,4796 cases of atezolizumab ADEs reported in the American FAERS database from 2017 to 2019 were retrospectively analyzed.Results The top three ADEs were febrile neutropenia(3.7%),anemia(2.9%),and acute renal failure(2.3%).In addition,the incidence rates of some ADEs were significantly different according to sex and age.The systematic organ classification of atezolizumab ADEs involved 32 systems,among which the top three were blood and lymphatic system disorders(585 cases,12.2%),gastrointestinal disorders(433 cases,9.0%),and infections and infestations(401 cases,8.4%).The reporting odds ratio(ROR)method was used to detect the ADR signals of atezolizumab.The ROR(95%confidence interval)of the top ADE,febrile neutropenia,was 39.236(33.757–45.604).In addition,we found 121 cases of complications associated with immune-related ADEs.Conclusion The ADRs of atezolizumab reported in the FAERS database were consistent with those mentioned in the instructions for atezolizumab use,suggesting that atezolizumab has an acceptable and controllable drug effect.

Clinical Efficacy and Adverse Reactions of Photodynamic Therapy in the Treatment of Malignant Skin Tumors and Precancerous Skin Diseases

The purpose of the study was to investigate the efficacy and safety of photodynamic therapy in the treatment of malignant skin tumors and precancerous skin diseases.First of all,100 patients with malignant skin tumor and pre-cancer skin disease admitted to our hospital from January 20,2018 to September 18,2018 were selected,and all of them adopted photodynamic therapy.The 100 patients included 40 cases of basal cell carcinoma,14 cases of squamous cell carcinoma,7 cases of proliferative erythema,9 cases of Bowen’s disease and 39 cases of solar keratosis.Among the 100 patients,77 cases had excellent curative effect,18 cases had good effect and 5 cases had poor effect,and the overall effective rate was 95%(95/100).After 6 months of follow-up,5 cases of basal cell carcinoma,2 cases of squamous cell carcinoma,0 cases of proliferative erythra,1 case of Bowen’s disease and 3 cases of solar keratosis recurred,with an overall recurrence rate of 14%(14/100).The adverse reactions of pruritus were 90%(90/100),81%(81/100),90%(90/100)and 3%(3/100).Therefore,the application of photodynamic therapy in the treatment of malignant skin tumors and precancerous skin diseases is not only effective,but also safe and not easy to relapse.

The effects of Chinese herbal medicines on Madopar dose and adverse reaction during the maintenance phase of Parkinson's disease:a systematic review with meta-analysis

Background:Parkinson’s disease is a progressive neurodegenerative disease,and is usually treated with levodopa combined with dopa decarboxylase inhibitor like Madopar.In order to improve the efficacy and reduce adverse reactions,Chinese herbal medicines are usually applied with Madopar to treat Parkinson’s disease in clinic.According to the results of certain randomized controlled trials,levodopa drugs combined with Chinese herbal medicines could achieve better effects like the improvement of clinical symptoms,the reduced incidence of adverse reactions,and the reduced dose of levodopa drugs(especially in the maintenance phase).However,not all the randomized controlled trials showed favorable effect on Parkinson’s disease.Therefore,it is necessary to find out how to effectively combine Chinese herbal medicines with Madopar.In order to evaluate the effects of Chinese herbal medicines on Madopar dose and adverse reaction during the maintenance phase of Parkinson’s disease,a meta-analysis was conducted.Methods:A systematic research was carried out for randomized controlled trials of combined Chinese herbal medicines and Madopar treatment for Parkinson’s disease during the maintenance phase published till August 2019.The primary outcome was the Madopar dose and secondary outcome was the incidence of adverse reaction.Data were pooled and analyzed with RevMan 5.3.Results:A total of 18 studies were included with 1,169 cases.However,study quality evaluation showed low methodological quality.Meta-analyses showed that the dose of Madopar in the treatment group was significantly lower than that in the control group,and the incidence of adverse reactions in the treatment group was also significantly lower than that in the control group.However,the correlation analysis showed that the reduction of Madopar dose was not related to the reduction of incidence of adverse reactions(P>0.05).There existed publication bias on the primary outcome and secondary outcome.Conclusions:Chinese herbal medicines could reduce the Madopar dose and adverse reaction during the maintenance phase of Parkinson’s disease treatment.This conclusion must be considered cautiously,for lack of studies of high quality.

Research progress on pharmacology and adverse reactions of gastrodin

Gastrodin(4-hydroxymethylphenyl-β-d-glucopyranoside)is an active ingredient with high content,which is isolated from the rhizome of Gastrodia elata.Gastrodin injections,tablets and capsules are currently the main gastrodin-related preparations in clinical practice,and gastrodin injections are the most widely used.This article will summarize pharmacology and adverse reactions of gastrodin to evaluate its safety,effectiveness and quality control.Gastrodin has pharmacological effects on central nervous system(vertigo,headache,insomnia,neurasthenia,convulsions and epilepsy,etc.),cardiovascular system and other diseases(osteoporosis,osteoarthritis and bone injury,etc.),but we still need to pay attention to its clinical adverse reactions(some patients may have dry mouth and nose,dizziness and stomach discomfort).In addition,further research is needed in other fields,such as health products,food,cosmetics,etc.We also need to further develop and explore the new pharmacological effects of gastrodin and expand its medicinal value.

Clinical features of adverse reactions associated with telbivudine

AIM: To analyze the clinical features and risk factors of adverse reactions associated with telbivudine. METHODS: Clinical data were collected from cases that presented with serious adverse reactions to telbivudine. We analyzed general information and medicine status, clinical features, results of examination, and misdiagnosis. RESULTS: Out of 105 patients who were treated with telbivudine for hepatitis B in an outpatient department from January, 2007 to January, 2008, five presented with serious adverse drug reactions. Most of these five patients had used other nucleoside analogues in the past. Four were treated with a combination of telbivudine and interferon or another nucleoside analogue, while the other received an increased dose of telbivudine. The main adverse reactions were myalgia and general weakness. This was accompanied by cardiac arrhythmia in one patient, and nervous symptoms in three. Serum creatine kinase was elevated. The rate of misdiagnosis was high. CONCLUSION: The adverse reactions were related to telbivudine, but the biological mechanism of the reactions is not yet clear. Combination therapy with interferon or another nucleoside analogue and a high dose may increase the risk of adverse reactions.
