We suggest that available medical information and digital/electronic methods could be used to manage this major healthcare problem for individual patients in real time. Methods: We searched the available digital applications and three literature databases using the medical subject heading terms, adverse drug reaction reporting systems or management, filtered by clinical trial or systemic reviews, to detect publications with data about ADR identification and management approaches. We reviewed the reports that had abstract or summary data or proposed or implemented methods or systems with potential to identify or manage ADRs in clinical settings. Results: The vast majority of the 481 reports used retrospectively collected data for groups of patients or were limited to surveying one population group or class of medication. The reports showed potential and definite associations of ADRs for specific drugs and problems, mostly, but not exclusively, for patients in hospitals and nursing homes. No reports described complete methods to collect comprehensive data on ADRs for individual patients in a healthcare system. The digital applications have ADR information, but all are too cumbersome or incomplete for use in active clinical settings. Several studies suggested that providing information about potential ADRs to clinicians can reduce these problems. Conclusion and Relevance: Although investigators and government agencies agree with the need, there is no comprehensive ADR management program in current use. Informing the patient’s healthcare practitioners of potential ADRs at the point of service has the potential for reduction of these complications, which should improve healthcare and reduce unneeded costs.展开更多

Objective: The personalized ADR early warning method, based on contextual ontology and rule learning, proposed in this study aims to provide a reference method for personalized health and medical information services. Methods: First, the patient data is formalized, and the user contextual ontology is constructed, reflecting the characteristics of the patient population. The concept of ontology rule learning is then proposed, which is to mine the rules contained in the data set through machine learning to improve the efficiency and scientificity of ontology rule generation. Based on the contextual ontology of ADR, the high-level context information is identified and predicted by means of reasoning, so the occurrence of the specific adverse reaction in patients from different populations is extracted. Results: Finally, using diabetes drugs as an example, contextual information is identified and predicted through reasoning, to mine the occurrence of specific adverse reactions in different patient populations, and realize personalized medication decision-making and early warning of ADR.展开更多

EU post-marketing ADR data is open to six categories of stakeholders: EMA, EC, medicines regulatory authorities in EEA member states, healthcare professionals and the public, Marketing Authorization Holders, academia, WHO and medicines regulatory authorities in third countries. The EU has implemented hierarchical opening for ADRs, with different levels containing different data and facing different stakeholders. Openness is divided into active and passive openness. In opening up data, the EU complies with relevant personal data protection laws to protect the privacy of individuals. The EU’s post-marketing adverse drug reaction data openness is characterized by a combination of data openness and privacy protection, active and passive openness, and a hierarchy of data openness. It is hoped that this can provide a reference for the opening up of post-marketing adverse drug reaction data in China.展开更多

Primary outcomes were the reduction in the severity of depression and adverse reactions associated with antidepressants, while secondary outcomes included remission rate, treatment response, social functioning, and change in antidepressant dose.The Grading of Recommendations Assessment, Development and Evaluation(GRADE) framework was used to evaluate the overall quality of evidence in the included studies.Results: This review included 16 studies(with a total of 1958 participants). Most studies were at high risk of performance bias and at low or unclear risk of selection bias, detection bias, attrition bias, reporting bias, and other bias. Analysis of the 16 RCTs showed that, compared with antidepressants alone, acupuncture along with antidepressants reduced the Hamilton Depression Rating Scale-17(HAMD-17) scores(standard mean difference [SMD]-0.44, 95% confidence interval [CI]-0.55 to-0.33, P < 0.01;I^(2)= 14%), Self-rating Depression Scale(SDS) scores(SMD-0.53, 95% CI-0.84 to-0.23, P < 0.01;I^(2)= 79%), and the Side Effect Rating Scale(SERS) scores(SMD-1.11, 95% CI-1.56 to-0.66, P < 0.01;I^(2)= 89%). Compared with antidepressants alone, acupuncture along with antidepressants improved World Health Organization Quality of Life-BREF scores(SMD 0.31, 95% CI 0.18 to 0.44, P < 0.01;I^(2)= 15%), decreased the number of participants who increased their antidepressant dosages(relative risk[RR] 0.32, 95% CI 0.22 to 0.48, P < 0.01;I^(2)= 0%), and resulted in significantly higher remission rates(RR1.52, 95% CI 1.26 to 1.83, P < 0.01;I^(2)= 0%) and treatment responses(RR 1.35, 95% CI 1.24 to 1.47, P < 0.01;I^(2)= 19%) in terms of HAMD-17 scores. The HAMD-17, SDS and SERS scores were assessed as low quality by GRADE and the other indices as being of moderate quality.Conclusion: Acupuncture as an adjunct to antidepressants may enhance the therapeutic effectiveness and reduce the adverse drug reactions in patients receiving antidepressants. These findings must be interpreted with caution, as the evidence was of low or moderate quality and there was a lack of comparative data with a placebo control.Systematic review registration: INPLASY202150008.展开更多

文摘Importance/Objective: Adverse Drug Reactions (ADRs) are unavoidable, but recognizing and addressing ADRs early can improve wellness and prevent permanent injury. We suggest that available medical information and digital/electronic methods could be used to manage this major healthcare problem for individual patients in real time. Methods: We searched the available digital applications and three literature databases using the medical subject heading terms, adverse drug reaction reporting systems or management, filtered by clinical trial or systemic reviews, to detect publications with data about ADR identification and management approaches. We reviewed the reports that had abstract or summary data or proposed or implemented methods or systems with potential to identify or manage ADRs in clinical settings. Results: The vast majority of the 481 reports used retrospectively collected data for groups of patients or were limited to surveying one population group or class of medication. The reports showed potential and definite associations of ADRs for specific drugs and problems, mostly, but not exclusively, for patients in hospitals and nursing homes. No reports described complete methods to collect comprehensive data on ADRs for individual patients in a healthcare system. The digital applications have ADR information, but all are too cumbersome or incomplete for use in active clinical settings. Several studies suggested that providing information about potential ADRs to clinicians can reduce these problems. Conclusion and Relevance: Although investigators and government agencies agree with the need, there is no comprehensive ADR management program in current use. Informing the patient’s healthcare practitioners of potential ADRs at the point of service has the potential for reduction of these complications, which should improve healthcare and reduce unneeded costs.
文摘Background: The fatality of adverse drug reactions (ADR) has become one of the major causes of the non-natural disease deaths globally, with the issue of drug safety emerging as a common topic of concern. Objective: The personalized ADR early warning method, based on contextual ontology and rule learning, proposed in this study aims to provide a reference method for personalized health and medical information services. Methods: First, the patient data is formalized, and the user contextual ontology is constructed, reflecting the characteristics of the patient population. The concept of ontology rule learning is then proposed, which is to mine the rules contained in the data set through machine learning to improve the efficiency and scientificity of ontology rule generation. Based on the contextual ontology of ADR, the high-level context information is identified and predicted by means of reasoning, so the occurrence of the specific adverse reaction in patients from different populations is extracted. Results: Finally, using diabetes drugs as an example, contextual information is identified and predicted through reasoning, to mine the occurrence of specific adverse reactions in different patient populations, and realize personalized medication decision-making and early warning of ADR.
文摘Objective To introduce the relevant big data platforms of FDA regulatory sciences and to provide reference for the construction of big data platform for China’s regulatory science under the“14th five-year plan”to deepen the reform of medical and health system.Methods A comparative analysis was made on China’s big data for regulatory science after studying the development process,operation mode,practical significance and characteristics of the big data platform for FDA regulatory science,which would help China to establish a perfect big database.Results and Conclusion The construction of big data platform for China’s regulatory science is not comprehensive compared with that in the United States.It is necessary to build data platforms in line with China’s national conditions through efforts in law,talents,standards,and other aspects.
文摘Systematically analyze the composition of post-marketing adverse drug reaction data and the open mode in the EU, and summarize its characteristics. EU post-marketing ADR data is open to six categories of stakeholders: EMA, EC, medicines regulatory authorities in EEA member states, healthcare professionals and the public, Marketing Authorization Holders, academia, WHO and medicines regulatory authorities in third countries. The EU has implemented hierarchical opening for ADRs, with different levels containing different data and facing different stakeholders. Openness is divided into active and passive openness. In opening up data, the EU complies with relevant personal data protection laws to protect the privacy of individuals. The EU’s post-marketing adverse drug reaction data openness is characterized by a combination of data openness and privacy protection, active and passive openness, and a hierarchy of data openness. It is hoped that this can provide a reference for the opening up of post-marketing adverse drug reaction data in China.
文摘Objective To explore the rules and characteristics of the adverse drug reactions(ADRs)of three Chinese patent medicines and three herbal formulas for the treatment of COVID-19,and to provide a reference for clinical safe medication.Methods The cases and ADR reports of the three Chinese patent medicines and three herbal formulas in PubMed,Web of Science,Springer Link,CNKI,Wanfang and VIP database were retrieved from December 2019 to May 2021.Then we extracted and analyzed the effective information included in the literature.Results and Conclusion According to the pre-developed retrieval plan,a total of 136 documents were obtained,and a total of 6 documents met the inclusion criteria finally.553 patients used three Chinese patent medicines and three herbal formulas,and there were 133 cases of adverse reactions.The adverse reactions of patients taking the three Chinese patent medicines and three herbal formulas can all be explained under the theory of traditional Chinese medicine,and the adverse reactions can be eliminated by adding or subtracting the flavor of the medicine or stopping the medicine.
文摘Objective:To examine the frequency and profile of spontaneous reports of adverse drug reactions(ADRs)sent to Ethiopia's pharmacovigilance(PV)database system.Methods:The descriptive and retrospective study analysed spontaneous ADR complaints reported to the PV database by healthcare professionals between 2013 and 2018.Spontaneous ADR reports that reached the PV center and met the minimum reporting criteria were identified and assessed in terms of reporting rate,patient characteristics,type of ADRs,suspected drugs,report sources,and reporters’profession.Results:A total of 657 spontaneous ADR reports were filed to the PV center between 2013 and 2018.During the study period,the reporting pattern of ADRs changed dramatically.The number of reports increased from 2013(n=12)and peaked in 2015(n=205),and then declined from 2016 to 2018(n=144,142 and 65 in 2016,2017 and 2018,respectively).Females had a higher percentage of reported cases(56.3%)than males(43.7%).The highest number of ADRs was reported in the age categories of 15-64 years(475,72.3%),followed by 0-14 years(154,23.4%),and 65 years and above(21,3.2%).Pharmacists reported the majority of ADRs(81.7%),followed by health officers(7.2%),nurses(5.8%),and physicians(5.2%).Skin and subcutaneous tissue abnormalities were the most commonly reported ADRs.The anatomical therapeutic chemicals code class"anti-infective for systemic use"was the most usually suspected medication.Trimethoprim with sulfamethoxazole as a combination ADRs was the most commonly reported drug that cause ADRs(14.2%).Conclusions:The number of ADRs reported in Ethiopia was small and unpredictable compared to developed countries,indicating the performance of PV system and level of awareness of health care professionals towards ADR reporting was not satisfactory.In order to increase the frequency of spontaneous reports,more efficient PV methods and public policies must be implemented.

文摘The liver plays a central role in the pharmacokinetics of drugs through drug metabolizing enzymes and transporters.Non-alcoholic steatohepatitis(NASH)causes disease-specific alterations to the absorption,distribution,metabolism,and excretion(ADME)processes,including a decrease in protein expression of basolateral uptake transporters,an increase in efflux transporters,and modifications to enzyme activity.This can result in increased drug exposure and adverse drug reactions(ADRs).Our goal was to predict drugs that pose increased risks for ADRs in NASH patients.Bibliographic research identified 71 drugs with reported ADRs in patients with liver disease,mainly non-alcoholic fatty liver disease(NAFLD),54 of which are known substrates of transporters and/or metabolizing enzymes.Since NASH is the progressive form of NAFLD but is most frequently undiagnosed,we identified other drugs at risk based on NASH-specific alterations to ADME processes.Here,we present another list of 71 drugs at risk of pharmacokinetic disruption in NASH,based on their transport and/or metabolism processes.It encompasses drugs from various pharmacological classes for which ADRs may occur when used in NASH patients,especially when eliminated through multiple pathways altered by the disease.Therefore,these results may inform clinicians regarding the selection of drugs for use in NASH patients.

文摘Background: Some depressed patients receive acupuncture as an adjunct to their conventional medications.Objective: This review aims to provide evidence on whether acupuncture can enhance the therapeutic effectiveness of antidepressants for treating depression, and explore whether acupuncture can reduce the adverse reactions associated with antidepressants.Search strategy: English and Chinese databases were searched for randomized controlled trials(RCTs)published until December 1, 2021.Inclusion criteria: RCTs with a modified Jadad scale score ≥ 4 were included if they compared a group of participants with depression that received acupuncture combined with antidepressants with a control group that received antidepressants alone.Data extraction and analysis: Meta-analysis was performed, and statistical heterogeneity was assessed based on Cochran’s Q statistic and its related P-value. Primary outcomes were the reduction in the severity of depression and adverse reactions associated with antidepressants, while secondary outcomes included remission rate, treatment response, social functioning, and change in antidepressant dose.The Grading of Recommendations Assessment, Development and Evaluation(GRADE) framework was used to evaluate the overall quality of evidence in the included studies.Results: This review included 16 studies(with a total of 1958 participants). Most studies were at high risk of performance bias and at low or unclear risk of selection bias, detection bias, attrition bias, reporting bias, and other bias. Analysis of the 16 RCTs showed that, compared with antidepressants alone, acupuncture along with antidepressants reduced the Hamilton Depression Rating Scale-17(HAMD-17) scores(standard mean difference [SMD]-0.44, 95% confidence interval [CI]-0.55 to-0.33, P < 0.01;I^(2)= 14%), Self-rating Depression Scale(SDS) scores(SMD-0.53, 95% CI-0.84 to-0.23, P < 0.01;I^(2)= 79%), and the Side Effect Rating Scale(SERS) scores(SMD-1.11, 95% CI-1.56 to-0.66, P < 0.01;I^(2)= 89%). Compared with antidepressants alone, acupuncture along with antidepressants improved World Health Organization Quality of Life-BREF scores(SMD 0.31, 95% CI 0.18 to 0.44, P < 0.01;I^(2)= 15%), decreased the number of participants who increased their antidepressant dosages(relative risk[RR] 0.32, 95% CI 0.22 to 0.48, P < 0.01;I^(2)= 0%), and resulted in significantly higher remission rates(RR1.52, 95% CI 1.26 to 1.83, P < 0.01;I^(2)= 0%) and treatment responses(RR 1.35, 95% CI 1.24 to 1.47, P < 0.01;I^(2)= 19%) in terms of HAMD-17 scores. The HAMD-17, SDS and SERS scores were assessed as low quality by GRADE and the other indices as being of moderate quality.Conclusion: Acupuncture as an adjunct to antidepressants may enhance the therapeutic effectiveness and reduce the adverse drug reactions in patients receiving antidepressants. These findings must be interpreted with caution, as the evidence was of low or moderate quality and there was a lack of comparative data with a placebo control.Systematic review registration: INPLASY202150008.
文摘Background Owing to complex treatment,critically ill children may experience alterations in their vital parameters.We investigated whether such hemodynamic alterations were temporally and causally related to drug therapy.Methods In a university pediatric intensive care unit,we retrospectively analyzed hemodynamic alterations defined as values exceeding the limits set for heart rate(HR)and blood pressure(BP).For causality assessment,we used the World Health Organization–Uppsala Monitoring Center(WHO–UMC)system,which categorizes the probability of causality as“certain,”“probable,”“possible,”and“unlikely.”Results Of 315 analyzed patients with 43,200 drug prescriptions,59.7%experienced at least one hemodynamic alteration;39.0%were affected by increased HR,19.0%by decreased HR,18.1%by increased BP,and 16.2%by decreased BP.According to drug information databases,83.9%of administered drugs potentially lead to hemodynamic alterations.Overall,88.3%of the observed hemodynamic alterations had a temporal relation to the administration of drugs;in 80.2%,more than one drug was involved.Based on the WHO–UMC system,a drug was rated as a“probable”causing factor for only 1.4%of hemodynamic alterations.For the remaining alterations,the probability ratings were lower because of multiple potential causes,e.g.,several drugs.Conclusions Critically ill children were frequently affected by hemodynamic alterations.The administration of drugs with potentially adverse effects on hemodynamic parameters is often temporally related to hemodynamic alterations.Hemodynamic alterations are often multifactorial,e.g.,due to administering multiple drugs in rapid succession;thus,the influence of individual drugs cannot easily be captured with the WHO–UMC system.

文摘AIM:To investigate the treatment pattern and safety of tafluprost for glaucoma and ocular hypertension(OH)in clinical practice in China.METHODS:This post-marketing observational study included patients who received tafluprost to lower intraocular pressure(IOP)within 30d between September 2017 and March 2020 in 20 hospitals in China.Adverse drug reactions(ADRs)during tafluprost treatment and within 30d after the treatment were collected.RESULTS:A total of 2544 patients were included in this study,of them 58.5%(1488/2544)had primary open angle glaucoma(POAG),21.9%(556/2544)had OH and 19.7%(500/2544)used tafluprost for other reasons.Of 359 ADRs occurred in 10.1%(258/2544)patients,and no serious adverse event occurred.The most common ADR was conjunctival hyperemia(128 ADRs in 124 patients,4.9%).Totally 1670 participants(65.6%)combined tafluprost with carbonic anhydrase inhibitors(CAIs;37.1%,620/1670),sympathomimetics(33.5%,559/1670),β-blockers(33.2%,555/1670),other prostaglandin analogs(PGAs;15.6%,260/1670)and other eye drops(15.1%,253/1670).The highest incidence of conjunctival hyperemia was noted in patients who received tafluprost in combination with other PGAs(23 ADRs in 23 patients,8.8%,23/260)and the lowest was in combination with CAIs(16 ADRs in 16 patients,2.6%,16/620).Tafluprost was applied in primary angle-closure glaucoma(41.6%,208/500),after glaucoma surgery(17.8%,89/500)and after non-glaucoma surgery(15.8%,79/500).CONCLUSION:Tafluprost is safe for POAG and OH,and tolerable when combined with other eye drops and under various clinical circumstances.
文摘BACKGROUND Pharmacovigilance(PV)is the activities and scientific studies conducted to detect,evaluate,understand or prevent adverse reactions and other drug-related problems.AIM To define the awareness and experiences of the clinicians on PV and adverse drug reactions(ADRs)in Turkey.METHODS The study was cross-sectional and analytical.Data were obtained through a questionnaire.The questionnaire was sent via e-mail.The survey was sent to 2030 physicians and 670 participated.RESULTS The most appropriate definition of PV was correctly defined by 53.9%of the participants.The most important goal of PV was correctly defined by 54.9%of the participants,and 27.3%of the participants were aware of the Turkish Pharmacovigilance Center.Nonsurgical physicians had better PV knowledge than surgical physicians.A total of 80.9%of the physicians who encountered ADRs,filled in the ADR notification form,and 8.8%received training on how to fill in the form.PV knowledge of the clinicians was not sufficient.Although half of the physicians encountered ADRs,the rates of seeing and filling in the ADR form were low.CONCLUSION Few of the physicians followed the current information about PV.The results provide more comprehensive data on PV practices and ADR reporting at a national level.
文摘BACKGROUND Pregabalin is widely used to treat neuropathic pain associated with postherpetic neuralgia.To our knowledge,this is the first report on simultaneously occurring dose-related adverse drug reactions(ADRs)of balance disorder,asthenia,peripheral edema,and constipation in an elderly patient after pregabalin.CASE SUMMARY A 76-year-old female with a history of postherpetic neuralgia was prescribed pregabalin(300 mg daily).After taking pregabalin for 7 d,the patient developed balance disorder,weakness,peripheral pitting edema(2+),and constipation.On days 8-14,the pregabalin dose was reduced to 150 mg/d based on creatinine clearance.The patient’s peripheral edema improved significantly with the disappearance of all other adverse symptoms.On day 15,the pregabalin dose was increased to 225 mg/d to relieve pain.Unfortunately,the symptoms mentioned earlier gradually reappeared after 1 wk of pregabalin treatment.However,the complaints were not as severe as when taking 300 mg/d pregabalin.The patient consulted her pharmacist by telephone and was advised to reduce the dose of pregabalin to 150 mg/d and add acetaminophen(0.5 g,q6h)to relieve pain.The patient’s ADRs gradually improved over the following week.CONCLUSION Older patients should be prescribed a lower initial dose of pregabalin.The dose should be titrated to the maximum tolerable dose to avoid dose-limiting ADR.Dose reduction and the addition of acetaminophen may help limit ADR and improve pain control.
