    BACKGROUND: Reporting adverse drug reactions (ADRs) has traditionally been the sole province of healthcare professionals. Since 2003 in Denmark, consumers have been able to report ADRs directly to the authorities. The objective of this study was to compare ADRs reported by consumers with ADRs...... medicines on level 1 of the anatomical therapeutic chemical (ATC) classification system. ADR reports from consumers were compared with reports from other sources (physicians, pharmacists, lawyers, pharmaceutical companies and other healthcare professionals). Chi-square and odds ratios (ORs) were calculated...... to investigate the dependence between type of reporter and reported ADRs (classified by ATC or SOC). FINDINGS: We analysed 6319 ADR reports corresponding to 15 531 ADRs. Consumers reported 11% of the ADRs. Consumers' share of 'serious' ADRs was comparable to that of physicians (approximately 45%) but lower than...

    Full Text Available ABSTRACT OBJECTIVE To describe different approaches to promote adverse drug reaction reporting among health care professionals, determining their cost-effectiveness. METHODS We analyzed and compared several approaches taken by the Northern Pharmacovigilance Centre (Portugal to promote adverse drug reaction reporting. Approaches were compared regarding the number and relevance of adverse drug reaction reports obtained and costs involved. Costs by report were estimated by adding the initial costs and the running costs of each intervention. These costs were divided by the number of reports obtained with each intervention, to assess its cost-effectiveness. RESULTS All the approaches seem to have increased the number of adverse drug reaction reports. We noted the biggest increase with protocols (321 reports, costing 1.96 € each, followed by first educational approach (265 reports, 20.31 €/report and by the hyperlink approach (136 reports, 15.59 €/report. Regarding the severity of adverse drug reactions, protocols were the most efficient approach, costing 2.29 €/report, followed by hyperlinks (30.28 €/report, having no running costs. Concerning unexpected adverse drug reactions, the best result was obtained with protocols (5.12 €/report, followed by first educational approach (38.79 €/report. CONCLUSIONS We recommend implementing protocols in other pharmacovigilance centers. They seem to be the most efficient intervention, allowing receiving adverse drug reactions reports at lower costs. The increase applied not only to the total number of reports, but also to the severity, unexpectedness and high degree of causality attributed to the adverse drug reactions. Still, hyperlinks have the advantage of not involving running costs, showing the second best performance in cost per adverse drug reactions report.

    Full Text Available We analyzed differences between spontaneously reported drug-induced (not including contrast media and contrast media-induced adverse reactions.Adverse drug reactions reported by an in-hospital pharmacovigilance center (St. Mary's teaching hospital, Daejeon, Korea from 2010-2012 were classified as drug-induced or contrast media-induced. Clinical patterns, frequency, causality, severity, Schumock and Thornton's preventability, and type A/B reactions were recorded. The trends among causality tools measuring drug and contrast-induced adverse reactions were analyzed.Of 1,335 reports, 636 drug-induced and contrast media-induced adverse reactions were identified. The prevalence of spontaneously reported adverse drug reaction-related admissions revealed a suspected adverse drug reaction-reporting rate of 20.9/100,000 (inpatient, 0.021% and 3.9/100,000 (outpatients, 0.004%. The most common adverse drug reaction-associated drug classes included nervous system agents and anti-infectives. Dermatological and gastrointestinal adverse drug reactions were most frequently and similarly reported between drug and contrast media-induced adverse reactions. Compared to contrast media-induced adverse reactions, drug-induced adverse reactions were milder, more likely to be preventable (9.8% vs. 1.1%, p < 0.001, and more likely to be type A reactions (73.5% vs. 18.8%, p < 0.001. Females were over-represented among drug-induced adverse reactions (68.1%, p < 0.001 but not among contrast media-induced adverse reactions (56.6%, p = 0.066. Causality patterns differed between the two adverse reaction classes. The World Health Organization-Uppsala Monitoring Centre causality evaluation and Naranjo algorithm results significantly differed from those of the Korean algorithm version II (p < 0.001.We found differences in sex, preventability, severity, and type A/B reactions between spontaneously reported drug and contrast media-induced adverse reactions.

    Full Text Available Ibuprofen is a commonly used drug available by prescription and over the counter for treatment of fever, joint pain, headache, migraine, inflammatory states. It is available in combination with paracetamol and various other drugs. Side effects associated with aspirin and non-steroidal anti-inflammatory drugs (NSAIDs are rash, gastrointestinal ulcers, hepatic toxicity, Steven Johnson syndrome, respiratory skin rashes, acute exacerbation of asthma and anaphylaxis. We have reported here severe distress hypersensitive reaction with ibuprofen induced hypersensitivity syndrome. Within two hours of consumption of ibuprofen patient developed severe bronchospasm, throat and laryngeal oedema leading to respiratory distress. He was treated with salbutamol, hydrocortisone, deriphylline and supportive oxygen, but did not respond and went into coma. Unlike acetaminophen, ibuprofen does not have any antidote hence managing adverse drug reactions (ADR due to ibuprofen is big challenge. Therefore understanding pathophysiology of ADR to Ibuprofen is necessary to manage the patient. Literature in the field of allergic drug reaction shows that epinephrine, a physiological antagonist of histamine is the first drug of choice for the treatment of allergic or drug induced angioedema, laryngeal oedema and bronchospasm due to its direct action on target organs. Such reactions should therefore be managed by epinephrine without loss of time. ADR due to ibuprofen could be prevented by (a avoiding unnecessary intake of drug, (b educating patients / families and public about adverse drug reactions (c surveillance and monitoring of drug reactions (d record keeping (e drug audit and (f reporting of ADR to state/central pharmacovigilance agency. We do observe doctors having misconception about adrenaline, its actions, usage and side effects especially cardio-vascular, hence are reluctant to use. But in severe violent adverse drug reaction we have to use our wisdom and judgement

  5. FDI report on adverse reactions to resin-based materials.

    Resin-based restorative materials are considered safe for the vast majority of dental patients. Although constituent chemicals such as monomers, accelerators and initiators can potentially leach out of cured resin-based materials after placement, adverse reactions to these chemicals are rare and reaction symptoms commonly subside after removal of the materials. Dentists should be aware of the rare possibility that patients could have adverse reactions to constituents of resin-based materials and be vigilant in observing any adverse reactions after restoration placement. Dentists should also be cognisant of patient complaints about adverse reactions that may result from components of resin-based materials. To minimise monomer leaching and any potential risk of dermatological reactions, resin-based materials should be adequately cured. Dental health care workers should avoid direct skin contact with uncured resin-based materials. Latex and vinyl gloves do not provide adequate barrier protection to the monomers in resin-based materials.

    Shinichi Matsuda

    Full Text Available Attitudes of healthcare professionals regarding spontaneous reporting of adverse drug reactions (ADRs in Japan are not well known, and Japan's unique system of surveillance, called early post-marketing phase vigilance (EPPV, may affect these reporting attitudes. Our objectives were to describe potential effects of EPPV and to test whether ADR seriousness, prominence, and frequency are related to changes in reporting over time.A manufacturer's database of spontaneous ADR reports was used to extract data from individual case safety reports for 5 drugs subject to EPPV. The trend of reporting and the time lag between ADR onset and reporting to the manufacturer were examined. The following indices for ADRs occurring with each drug were calculated and analyzed to assess reporting trends: Serious:Non-serious ratio, High prominence:Low prominence ratio, and High frequency:Low frequency ratio.For all 5 drugs, the time lag between ADR onset and reporting to the manufacturer was shorter in the EPPV period than in the post-EPPV period. All drugs showed higher Serious:Non-serious ratios in the post-EPPV period. No specific patterns were observed for the High prominence:Low prominence ratio. The High frequency:Low frequency ratio for peginterferon alpha-2a and sevelamer hydrochloride decreased steadily throughout the study period.Healthcare professionals may be more likely to report serious ADRs than to report non-serious ADRs, but the effect of event prominence on reporting trends is still unclear. Factors associated with ADR reporting attitude in Japan might be different from those in other countries because of EPPV and the involvement of medical representatives in the spontaneous reporting process. Pharmacovigilance specialists should therefore be cautious when comparing data between different time periods or different countries. Further studies are needed to elucidate the underlying mechanism of spontaneous ADR reporting in Japan.

    Full Text Available Spontaneous reporting (SPR and intensive monitoring are the conventional systems used for detecting, recording, and reporting adverse drug reactions (ADRs. Using spontaneous reporting a lot of successes has been made as existing ADRs were identified and new ones prevented through this methods. The aim of this appraisal was to evaluate the knowledge, attitude, and the practice of medical students with regards to ADRs reporting and to see if differences exist between the level of study and genders. The questionnaire was adopted, modified, and validated from previous studies. It comprised of 25 questions. It was administered year-IV and V medical students of Bayero University Kano, Nigeria. The data collected were coded and analyzed using the Statistical Package for the Social Sciences (SPSS version 20, currently known as IBM SPSS Statistics. The response rate was 74%. Among the 108 participants, 80% got the definition of ADRs correct; 63% of them knew the precise functions of pharmacovigilance (PV. In addition, 82% strongly agreed that ADR reporting is health care workers responsibility; 82% also said PV should be taught in detail. Meanwhile, 99% have noticed patient experiencing ADRs; 67% said even mild ADRs should be reported. The outcome of this study showed good knowledge and attitude with respect to ADRs and PV among the medical students surveyed. Unfortunately, the practice of medical students was found to be unsatisfactory. There is a need to upgrade the students teaching the curriculum with respect to ADRs monitoring.

    Adverse drug reactions (ADRs) are considered as one of the leading causes of death among hospitalized patients. Thus reporting of adverse drug reactions become an important phenomenon. Spontaneous adverse drug reaction reporting form is an essential component and a major tool of the pharmacovigilance system of any country. This form is a tool to collect information of ADRs which helps in establishing the causal relationship between the suspected drug and the reaction. As different countries have different forms, our aim was to study, analyze the suspected adverse drug reaction reporting form of different countries, and assess if these forms can capture all the data regarding the adverse drug reaction. For this analysis we identified 18 points which are essential to make a good adverse drug reaction report, enabling proper causality assessment of adverse reaction to generate a safety signal. Adverse drug reaction reporting forms of 10 different countries were collected from the internet and compared for 18 points like patient information, information about dechallenge-rechallenge, adequacy of space and columns to capture necessary information required for its causality assessment, etc. Of the ADR forms that we analyzed, Malaysia was the highest scorer with 16 out of 18 points. This study reveals that there is a need to harmonize the ADR reporting forms of all the countries because there is a lot of discrepancy in data captured by the existing ADR reporting forms as the design of these forms is different for different countries. These incomplete data obtained result in inappropriate causality assessment.

    We conducted pharmacovigilance data mining for a β-lactam antibiotics, amoxicillin, and compare the adverse events (AEs) with the drug labels of 9 countries including Korea, USA, UK, Japan, Germany, Swiss, Italy, France, and Laos. We used the Korea Adverse Event Reporting System (KAERS) database, a nationwide database of AE reports, between December 1988 and June 2014. Frequentist and Bayesian methods were used to calculate disproportionality distribution of drug-AE pairs. The AE which was detected by all the three indices of proportional reporting ratio (PRR), reporting odds ratio (ROR), and information component (IC) was defined as a signal. The KAERS database contained a total of 807,582 AE reports, among which 1,722 reports were attributed to amoxicillin. Among the 192,510 antibiotics-AE pairs, the number of amoxicillin-AE pairs was 2,913. Among 241 AEs, 52 adverse events were detected as amoxicillin signals. Comparing the drug labels of 9 countries, 12 adverse events including ineffective medicine, bronchitis, rhinitis, sinusitis, dry mouth, gastroesophageal reflux, hypercholesterolemia, gastric carcinoma, abnormal crying, induration, pulmonary carcinoma, and influenza-like symptoms were not listed on any of the labels of nine countries. In conclusion, we detected 12 new signals of amoxicillin which were not listed on the labels of 9 countries. Therefore, it should be followed by signal evaluation including causal association, clinical significance, and preventability. PMID:27510377

  12. Limitations and obstacles of the spontaneous adverse drugs reactions reporting: Two "challenging" case reports

    Full Text Available Introduction: Nowadays, based on several epidemiological data, iatrogenic disease is an emerging public health problem, especially in industrialized countries. Adverse drugs reactions (ADRs are extremely common and, therefore, clinically, socially, and economically worthy of attention. Spontaneous reporting system for suspected ADRs represents the cornerstone of the pharmacovigilance, because it allows rapid detection of potential alarm signals related to drugs use. However, spontaneous reporting system shows several limitations, which are mainly related to under-reporting. In this paper, we describe two particular case reports, which emphasize some reasons of under-reporting and other common criticisms of spontaneous reporting systems. Materials and Methods: We performed a computer-aided search of Medline, PubMed, Embase, Cochrane library databases, national and international databases of suspected ADRs reports in order to identify previous published case reports and spontaneous reports about the ADRs reviewed in this paper, and to examine the role of suspected drugs in the pathogenesis of the described adverse reactions. Results: First, we reported a case of tizanidine-induced hemorrhagic cystitis. In the second case report, we presented an episode of asthma exacerbation after taking bimatoprost. Through the review of these two cases, we highlighted some common criticisms of spontaneous reporting systems: under-reporting and false causality attribution. Discussion and Conclusion: Healthcare workers sometimes do not report ADRs because it is challenging to establish with certainty the causal relationship between drug and adverse reaction; however, according to a key principle of pharmacovigilance, it is always better to report even a suspicion to generate an alarm in the interest of protecting public health.

An overview of reports of suspected adverse drug reactions received by the centre during the period March 2004 to February 2006 is presented. A total of 21 reports was received in the 2-year period, continuing the decline in the number of reports to a lower figure than in any previous year. This is surprising considering the legal obligation of the veterinary professionals to report all adverse drug reactions. Once again the majority of reports involved suspected adverse reactions that occurred in dogs and cats. Most of the products implicated were stock remedies. Veterinarians predominantly administered these products.

    Full Text Available Adverse drug reaction (ADR is poorly reported globally but more in developing countries with poor participation by health professionals. Currently, there is no known literature on the Nigerian pharmacy students’ knowledge on ADR reporting. Hence the purpose of this study was to find out the level of knowledge of pharmacy students on the concept of pharmacovigilance and adverse drug reaction reporting and also to evaluate their opinions on the National Pharmacovigilance Centre guidelines on adverse drug reaction reporting. A pretested 34-item semi-structured questionnaire was administered among 69 pharmacy undergraduate students in their penultimate and final years that consented to take part in the study, in one of the universities in Nigeria. The study was carried out strictly adhering to the principles outlined in the Helsinki declaration of 1964, which was revised in 1975. The questionnaire used had four sections which included a section on biographical data, a section which evaluated the students knowledge on the concept of pharmacovigilance and adverse drug reaction reporting, a section on students personal experiences of adverse drug reactions and modes of reporting them and the final section of the questionnaire evaluated the students’ opinions on the National Pharmacovigilance Centre guidelines for reporting adverse drug reactions. Descriptive statistics, Mann-Whitney U and Kruskal Wallis statistical tests were used to analyze the data obtained. None of the participants knew the sequence of reporting ADR. More than half, 40(58.0% had heard about pharmacovigilance at symposiums, 7(10.1% during clinical clerkship program and 18(26.1% from media jingles. Twenty nine (42.0% agreed that pharmacovigilance was in their curriculum, however only 16(23.2% could define the term correctly. None of the participants had seen or used an ADR form prior to the study, but the students could easily identify and describe the type of ADR they had

    Full Text Available Adverse reaction to cosmetics constitute a small but significant number of cases of contact dermatitis with varied appearances. These can present as contact allergic dermatitis, photodermatitis, contact irritant dermatitis, contact urticaria, hypopigmentation, hyperpigmentotion or depigmentation, hair and nail breakage. Fifty patients were included for the study to assess the role of commonly used cosmetics in causing adverse reactions. It was found that hair dyes, lipsticks and surprisingly shaving creams caused more reaction as compared to other cosmetics. Overall incidence of contact allergic dermatitis seen was 3.3% with patients own cosmetics. Patch testing was also done with the basic ingredients and showed positive results in few cases where casual link could be established. It is recommended that labeling of the cosmetics should be done to help the dermatologists and the patients to identify the causative allergen in cosmetic preparation.

The present study was designed to assess first-year residents’ knowledge of ADR reporting.Methods: First-year postgraduate doctors at a private medical college completed a structured questionnaire. The responses were analyzed by nonparametric methods.Results: All doctors were aware of the term “adverse drug reactions.” Fifty percent of the doctors reported being taught about ADR reporting during their undergraduate teaching, and 50% had witnessed ADRs in their internship training. Ten percent of patients suffering an ADR observed and reported by doctors required prolonged hospitalization for treatment as a result. Only 40% of interns reported the ADRs that they observed, while 60% did not report them. Twenty-eight percent reported ADRs to the head of the department, 8% to an ADR monitoring committee, and 4% to the pharmacovigilance center. Eighty-six percent of the doctors surveyed felt that a good knowledge of undergraduate clinical pharmacology therapeutics would have improved the level of ADR reporting.Conclusion: The knowledge of first-year doctors regarding ADR reporting is quite poor. There is a dire need to incorporate ADR reporting into undergraduate teaching, and to reinforce this during internships and periodically thereafter.Keywords: ADR reporting, pharmacovigilance, first-year postgraduate doctors

    The musculoskeletal system can be a target organ for adverse drug reactions (ADRs). Drug-induced muscle, bone or connective tissue injuries may be due to, i), primary direct drug action, or, ii), undirected consequence of generalized drug-induced disease. Musculoskeletal ADRs may be only temporarily disabling, such as muscle cramps, as well as in other cases may be serious and life-threatening, such as rhabdomyolysis. In the last few years there has been an increasing awareness of musculoskeletal ADRs. Some recent drug safety issues dealt with serious or uncommon musculoskeletal reactions like rhabdomyolysis associated to statins and tendon rupture associated to fluoroquinolones. In this review, we firstly selected those drug classes having a significantly high percentage of musculoskeletal disorder reports in the WHO adverse drug reaction database, maintained by the Uppsala Monitoring Centre. Secondly, the different musculoskeletal ADRs were closely analyzed through the data obtained from an Italian interregional ADRs spontaneous reporting database. The findings on drugs associated to different musculoskeletal disorders, have been integrated with a review of the epidemiological data available in the literature. For the most involved drugs (HMG-CoA reductase inhibitors, fluoroquinolones, corticosteroids, bisphosphonates, retinoids) the underlying musculoskeletal ADR mechanisms were also reviewed and discussed.

    Suspected adverse reactions (SARs) reported for Cartrophen Vet (100 mg sodium pentosan polysulphate/ml) to the Veterinary Medicines Directorate in the UK for the period January 1991 to October 1999 were reviewed. Of the 161 reports, 28 were probably product related, 54 were possibly product related, 71 were unlikely to be related and eight were unclassified. An estimated real incidence of adverse reactions probably and possibly associated with Cartrophen Vet of 0.074 per cent on an individual dose basis was calculated (assuming only 10 per cent were documented due to underreporting). Sixty-two SARs (38.5 per cent) documented emesis, 22 (35.5 per cent) of which were product related (onset five to 15 minutes after administration). Sixty-eight SARs (42.2 per cent) documented general changes to demeanour, 10 (14.7 per cent) were product related (lethargy and/or mild depression and/or mild inappetence lasting up to two days after administration). Six SARs were considered likely to be associated with concurrently administered carprofen. Cartrophen Vet had a low incidence of side effects that were mild and transitory. PMID:12779171

    Full Text Available Spontaneous reporting on adverse drug reactions (ADR has been established in Malaysia since 1987, and although these reports are monitored by the Malaysia drug monitoring authority, the National Pharmaceutical Control Bureau, information about ADRs in the paediatric patient population still remains unexplored. The aims of this study, therefore, were to characterize the ADRs reported in respect to the Malaysian paediatric population and to relate the data to specific paediatric age groups.Data on all ADRs reported to the National Pharmaceutical Control Bureau between 2000 and 2013 for individuals aged from birth to 17 years old were analysed with respect to age and gender, type of reporter, suspected medicines (using the Anatomical Therapeutic Chemical classification, category of ADR (according to system organ class as well as the severity of the ADR.In total, 11,523 ADR reports corresponding to 22,237 ADRs were analysed, with half of these reporting one ADR per report. Vaccines comprised 55.7% of the 11,523 ADR reports with the remaining being drug related ADRs. Overall, 63.9% of ADRs were reported for paediatric patients between 12 and 17 years of age, with the majority of ADRs reported in females (70.7%. The most common ADRs reported were from the following system organ classes: application site disorders (32.2%, skin and appendages disorders (20.6%, body as a whole general disorders (12.8% and central and peripheral nervous system disorders (11.2%. Meanwhile, ADRs in respect to anti-infectives for systemic use (2194/5106; 43.0% were the most frequently reported across all age groups, followed by drugs from the nervous system (1095/5106; 21.4%. Only 0.28% of the ADR cases were reported as fatal. A large proportion of the reports were received from healthcare providers in government health facilities.ADR reports concerning vaccines and anti-infectives were the most commonly reported in children, and are mainly seen in adolescents, with most of

    Full Text Available Introduction: Adverse drug reactions (ADRs are threat to the patient’s safety and the quality of life, and they increase the cost of health care. Spontaneous ADR reporting system mainly relies on physicians, but also pharmacists, nurses, and even patients. The aim of this study was to explore attitudes, barriers, and possible improvements to ADR reporting practices in Bosnia and Herzegovina.Methods: A self-reported questionnaire was developed to collect data on the perception of pharmacovigilance practice and ADR reporting. The survey was conducted in the period between September, 2014 and October, 2014.Results: The response rate was 73% (44 of 60 and 93% (148 of 160 among the pharmacist and family medicine physician groups, respectively. Regarding the attitudes to pharmacovigilance practice and reporting, both the pharmacists and physicians found the practices important. The majority of pharmacists and physicians in year 2014 did not report any ADR, while 18% of the pharmacists and 12% of the physicians, who participated in this study, reported one ADR. Reporting procedure, uncertainty, and their exposure were the main barriers to reporting ADRs for the pharmacists. The physicians claimed lack of knowledge to whom to report an ADR as the main barrier. A significant number of the respondents thought that additional education in ADR reporting would have a positive impact, and would increase the ADR reporting rate.Conclusions: Despite the overall positive attitude towards ADR reporting, the reporting rate in Bosnia and Herzegovina is still low. Different barriers to the ADR reporting have been identified, and there is also the need for improvements in the traditional education in this field.

    Full Text Available Abstract Background Previously, adverse event reports (AERs submitted to the US Food and Drug Administration (FDA database were reviewed to confirm platinum agent-associated hypersensitivity reactions. The present study was performed to confirm whether the database could suggest the hypersensitivity reactions caused by anticancer agents, paclitaxel, docetaxel, procarbazine, asparaginase, teniposide, and etoposide. Methods After a revision of arbitrary drug names and the deletion of duplicated submissions, AERs involving candidate agents were analyzed. The National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 was applied to evaluate the susceptibility to hypersensitivity reactions, and standardized official pharmacovigilance tools were used for quantitative detection of signals, i.e., drug-associated adverse events, including the proportional reporting ratio, the reporting odds ratio, the information component given by a Bayesian confidence propagation neural network, and the empirical Bayes geometric mean. Results Based on 1,644,220 AERs from 2004 to 2009, the signals were detected for paclitaxel-associated mild, severe, and lethal hypersensitivity reactions, and docetaxel-associated lethal reactions. However, the total number of adverse events occurring with procarbazine, asparaginase, teniposide, or etoposide was not large enough to detect signals. Conclusions The FDA's adverse event reporting system, AERS, and the data mining methods used herein are useful for confirming drug-associated adverse events, but the number of co-occurrences is an important factor in signal detection.

    The Maltese Medicines Authority was tasked with developing a reporting form that captures high-quality case information on adverse drug reactions (ADRs) and medication errors in order to fulfil its public-health obligations set by the European Union (EU) legislation on pharmacovigilance. This paper describes the process of introducing the first combined ADR/medication error reporting form in the EU for health-care professionals, the analysis of reports generated by it and the promotion of the system. A review of existing ADR forms was carried out and recommendations from the European Medicines Agency and World Health Organization audits integrated. A new, combined ADR/medication error reporting form was developed and pilot tested based on case studies. The Authority's quality system (ISO 9001 certified) was redesigned and a promotion strategy was deployed. The process used in Malta can be useful for countries that need to develop systems relative to ADR/medication error reporting and to improve the quality of data capture within their systems.

    Background A voluntary procedure for reporting adverse drug reactions (ADRs) was formally put in place in 1989. However, only a small proportion of ADR reports are actually forwarded to the national monitoring center. To identify the reasons for underreporting, the authors investigated the awareness and attitudes of healthcare professionals (doctors, nurses, and administrators) toward the ADR system in China. In addition, the authors sought to formulate approaches to improve the current ADR reporting system.Methods Structured interviews were carried out in 16 hospitals selected from 27 municipal hospitals in Wuhan, Hubei Province, China. A questionnaire survey of a stratified random sample of approximately 15% of healthcare professionals in each selected hospital was conducted during February to March 2003.Results The response rate of this survey was 85%. One thousand six hundred and fifty-three questionnaires were used in the final analysis. Only 2.7% of the healthcare professionals had a correct understanding to the definition of ADR. Eighty-nine point two percent of the healthcare professionals had encountered ADRs. Ninety-four percent of them were aware of the need to report these to the ADR monitoring center. However, only 28.5% of doctors, 22.8% of nurses, and 29.7% of administrators actually submitted a report. For the most part, they reported ADRs to the hospital pharmacy (66.0%), to other departments in the hospital (72.5%), and to the pharmaceutical industry (23.0%), rather than to the national monitoring center (2.9%) or regional monitoring center (9.5%). Severe or rare ADRs and ADRs to new products were generally perceived to be significant enough to report. Sixty-two point one percent of the healthcare professionals had encountered ADRs, yet not reported them to anybody. The major reasons for not reporting included no knowledge of the reporting procedure (71.4%), unavailability of the reporting center mailing address (67.9%), unavailability of the ADR

    The operating theatre exposes patients to myriad potential agents which could result in a life-threatening anaphylactic reaction. Anaesthetic drugs, blood products, and latex are only some of the possible allergens. Reactions are deemed to be anaphylactic when immediate sensitivity is combined with cardiovascular collapse. A patient who had a known allergy to shellfish presented for first time cardiopulmonary bypass. The perfusion team were concerned that there was a realistic possibility that an adverse reaction to protamine could occur. Anaphylactic reactions to protamine in patients allergic to fish have been reported. The anaesthetic team were informed and the necessary precautions taken. We report on the outcome for our patient and also discuss other risk factors and the types of reactions that can result when an adverse reaction to protamine occurs.

    Generic formulations represent a way to reduce the costs of brand compounds when their patent is expired. While, the bio-equivalence in generic drugs is guaranteed, some excipients as well as dyes could be different and this could reduce the drug safety. Herein, we report the development of Adverse Drug Reactions (ADRs) in two patients after the switch from brand to generic formulations. We have tested cytochrome P450 enzymes expression as well as drug serum levels. None of these markers were altered. Checking deeply into both patient's medical history, they harbored poly-sensitivity or allergy to pollen and graminacea and used different active ingredients for different health problems coming from the same generic company Almus(®). This company used different dyes and excipients compared to the branded drugs made by distinguished companies. In conclusion, we strongly suggest to both pharmacists and physicians to be careful in giving the advice to change the drug, thinking to reduce health sanitary costs without considering the personal clinical history of each one. Paradoxically this behavior is causing other health issues, bringing to an increase of the overall costs for patients as well as for National Health System.

    Treatment with desmopressin diacetate arginine vasopressin (DDAVP) and its withdrawal are associated with side effects. We present a rare case of severe biphasic adverse reactions induced by DDAVP and its withdrawal in a 63-year-old female patient. A lump in the left axillary region was biopsied, and she received DDAVP after surgery. The following day, she lost consciousness, with foaming at the mouth and seizures. Hypotonic encephalopathy was considered. DDAVP was ceased, and she received electrolytes. On day 1, she displayed low blood pressure and increased urine output. She received DDAVP and dopamine as well as electrolytes. The patient was ambulatory on day 7 and was discharged without brain abnormalities on MRI. In conclusion, severe hyponatremia induced by DDAVP and massive polyuria and hypovolemic shock induced by DDAVP withdrawal are life-threatening conditions. This case underlines the need to be vigilant when administering DDAVP and to monitor for any side effects. PMID:27142268

    This article focused on early warning signals regarding the safety of parenterally administered Xiyanping. The study data was obtained from reports made between 2005-2012 from the national spontaneous reporting system (SRS). Proportion reporting ratio (PRR) and Bayesian confidence propagation neural network (BCPNN) algorithms were used to analyse: erythra, pruritus, anaphylactoid reactions and shiver with cold, these 4 adverse drug reactions had a total count of more than 500 events. The article found that Xiyanping's incidence rate of erythra was higher than for background-drugs in every year and in every season. Pruritus was an early warning signal in the second season of 2009, and anaphylactoid reaction was an early warning signal in the fourth season of 2011 and in the second season of 2012. There was however no early warning signal indicated by shiver with cold. This data indicates that erythra maybe an adverse drug reactions to parenterally administered Xiyanping, and if the incidence rate of pruritus and anaphylactoid reaction rises attention should be paid to its safety.

    Objectives To assess community pharmacists'/pharmacy technicians' knowledge and perceptions about adverse drug reactions (ADRs) and barriers towards the reporting of such reactions in Dhaka, Bangladesh. Method A cross-sectional study was planned to approach potential respondents for the study. A self-administered questionnaire was delivered to community pharmacists/pharmacy technicians (N=292) practising in Dhaka, Bangladesh. Results The overall response to the survey was 69.5% (n=203). The majority of the sample was comprised of pharmacy technicians (152, 74.9%) who possessed a diploma in pharmacy, followed by pharmacists (37, 18.2%) and others (12, 5.9%). Overall, 72 (35.5%) of the respondents disclosed that they had experienced an ADR at their pharmacy, yet more than half (105, 51.7%) were not familiar with the existence of an ADR reporting body in Bangladesh. Exploring the barriers to the reporting of ADRs, it was revealed that the top four barriers to ADR reporting were ‘I do not know how to report (Relative Importance Index (RII)=0.998)’, ‘reporting forms are not available (0.996)’, ‘I am not motivated to report (0.997)’ and ‘Unavailability of professional environment to discuss about ADR (RII=0.939)’. In addition to these, a majority (141, 69.46%) were not confident about the classification of ADRs (RII=0.889) and were afraid of legal liabilities associated with reporting ADRs (RII=0.806). Moreover, a lack of knowledge about pharmacotherapy and the detection of ADRs was another major factor hindering their reporting (RII=0.731). Conclusions The Directorate of Drug Administration in Bangladesh needs to consider the results of this study to help it improve and simplify ADR reporting in Bangladeshi community pharmacy settings.

    Objective: Objective of this study was to assess the attitude of nurses and pharmacists towards adverse drug reactions (ADRs) reporting. Methods: The questionnaire was designed based on extended “Inman seven deadly sins.” Two hundred and seventy-two respondents were selected by stratified sampling technique. The questionnaires were delivered to the respondents at their places of practice. The data generated were analyzed by Sigma XL Software Inc. Findings: There was no statistically significant relationship between demographic profiles and reporting attitude except for qualification. On extended “Inman seven deadly sins” awareness of reporting protocol and nearby center for ADRs reporting were low 27.3 and 7.5%, respectively. However, respondents’ score on components of attitude of ADRs reporting is generally encouraging. On comparative basis, no statistical significance exists between pharmacists and nurses. Conclusion: The study showed that attitude of respondents towards ADRs reporting is good. However, there is a need for targeted health education intervention among these cadres of health-care professionals, especially on aspects of awareness of reporting protocol and reporting center.

    Early studies suggested that the centrally acting non-opioid and non-steroidal analgesic flupirtine (FLP) has no potential for abuse. However, FLP's agonistic effects at the GABAA receptor might prime addictive behaviors, and literature provides some anecdotal reports on FLP abuse/dependence. To shed more light on this topic we acquired and evaluated data obtained from a national German pharmacovigilance database. We analyzed all reports of FLP abuse/dependence that were recorded in the database of the German Federal Institute for Drugs and Medical Devices (BfArM). A total of n = 48 reports of FLP abuse/dependence could be identified (mean age 45 years, 62.5% female). First reports were submitted to BfArM in 1991 with increasing numbers of annual reports from the year 2006 on. Mean daily FLP dosage was 805 mg (range 200-3,000 mg). Current or previous substance abuse/dependence was reported in 21% and 17%, respectively. Mean duration of FLP abuse/dependence until report to BfArM was 23 months (range 1-84 months). Withdrawal syndromes after discontinuation of FLP were reported in n = 9 (19%). Our findings strengthen the hypothesis that FLP features a potential to cause addictive behaviors. Female sex, age >40 years, and long-term FLP-treatment may be possible risk factors for the development of FLP abuse/dependence. PMID:24037995

    Full Text Available Background: Pharmacovigilance is a useful to assure the safety of medicines and protect consumers from their harmful effects. Healthcare professionals should consider Adverse Drug Reaction (ADR reporting as part of their professional obligation and participate in the existent pharmacovigilance programs in their countries. In India, the National PV Program was re-launched in July 2010. Objectives: This survey was conducted in order to assess the knowledge, attitude and practice of Indian pharmacists with the aim of exploring the pharmacists′ participation in ADR reporting system, identifying the reasons of under reporting and determining the steps that could be adopted to increase reporting rates. Materials and Methods: A cross-sectional survey was carried out among the pharmacists in India using a pretested questionnaire with 33 questions (10 questions on knowledge, 6 on attitude, 7 on practice, 7 on future of ADR reporting in India and 3 on benefits of reporting ADRs.. The study was conducted, over a period of 3 months from May 2012 to July 2012. Results: Out of the 600 participants to whom the survey was administered, a total of 400 were filled. The response rate of the survey was 67%. 95% responders were knowledgeable about ADRs. 90% participants had a positive attitude towards making ADRs reporting mandatory for practicing pharmacists. 87.5% participants were interested in participating in the National Pharmacovigilance program, in India. 47.5% respondents had observed ADRs in their practice, and 37% had reported it to the national pharmacovigilance center. 92% pharmacists believed reporting ADRs immensely helped in providing quality care to patients. Conclusion : The Indian pharmacists have poor knowledge, attitude, and practice (KAP towards ADR reporting and pharmacovigilance. Pharmacists with higher qualifications such as the pharmacists with a PharmD have better KAP. With additional training on Pharmacovigilance, the Indian Pharmacists

    Full Text Available Aim: Spontaneous voluntary adverse drug reaction (ADR reporting is paramount to the success of the Pharmacovigilance Programme of India. There has however been minimal and sporadic voluntary reporting of ADR's at the ADR Monitoring Centre (AMC Gangtok, Sikkim. Knowledge, perception, attitude, and awareness of health professionals are determinants of reporting practices. This questionnaire study aims at evaluating these indicators in the teaching hospital attached to the Medical Institute and find out methods to improve existing reporting practices. Materials and Methods: This is a cross-sectional questionnaire-based observational study carried out in the Medical, Surgical and Pathology Departments of the Teaching Hospital, Gangtok, Sikkim over a period of 2 months. The questionnaires were filled by the respondents and returned back to us within the next 24 h. Data obtained from filled questionnaires were thereby analyzed. Results: The overall correct response rate to the knowledge-based questions was 56.3%. While 97% of respondents were of the view that ADR reporting was necessary, 35% of the respondents felt that the difficulty in deciding the causality of an ADR discouraged them from reporting. 79% of the respondents were not aware of the presence of an AMC affiliated to the hospital, and 87% of the respondents admitted that they were not sending filled ADR forms to the AMC. Conclusions: The study indicates that the respondents have an average knowledge and positive attitude toward ADR reporting and pharmacovigilance. There is however a lack of awareness and poor ADR reporting practices. Efforts are required to enhance awareness and attitude toward pharmacovigilance and ADR reporting.

    2015-11-01

    Full Text Available Introduction: Psychotropic drugs are often implicated in cutaneous adverse drug reactions. While most of these reactions have a benign character, it is still important, however, to consider its role in the increasing stigma and treatment adherence. A small number of the cutaneous adverse drug reactions can develop into serious and potentially fatal conditions. Objectives: This article aims to review the most common cutaneous adverse drug reactions in patients taking psychotropic drugs. Methods: In this study, a search was carried out in the MEDLINE database for English language articles published , from 1999 to 2014, using as keywords: psychiatric, psychotropic, cutaneous, adverse reaction, antidepressive agents, antipsychotics, benzodiazepines, mood stabilizers, anticonvulsant, dementia. Information available from the Portuguese regulatory and supervising agency (Infarmed was also included.Results: 121 articles were found with reference to cutaneous adverse drug reactions associated with psychotropic drugs. The drugs most frequently reported as associated with such adverse effects were anticonvulsants used as mood stabilizers, followed by the antipsychotics . The antidementia drugs were rarely associated with serious cutaneous adverse reactions. Discussion and Conclusion: Cutaneous drug adverse reactions are common in psychiatric clinical practice and typically are minor in severity. The most severe reactions are most often associated with the use of mood stabilizing medications. Some of these side effects can be solved with reduction or drug discontinuation. More severe cases should be referred to a specialist in dermatology.

The System Organ Classes most frequently associated with ADRs were: skin and subcutaneous tissue, gastrointestinal, respiratory thoracic and mediastinal, and nervous system disorders. The most common Anatomical Therapeutic Chemical classes involved in admissions were J (anti-infectives and immunomodulating agents), B (blood and blood-forming organs), and N (nervous system). Older age, yellow and red triage, higher number of concomitantly taken drugs, and previous attendance in ED for the same ADR were significantly associated with an increased risk of hospitalization. The total cost associated with ADR management was €5,184,270, with a mean cost per patient of €585. Fifty-eight percent of the economic burden was defined as probably/definitely preventable. Conclusion ADRs are a serious health/economic issue in EDs. This assessment provides a thorough estimation of their seriousness, preventability, and burden impact in a large population from a representative European region. PMID

    A lack of systematic pharmacoepidemiological studies investigating adverse drug reactions (ADRs) to anticonvulsants makes it difficult to assess accurately the incidence of anticonvulsant-related ADRs. Most of the available information in this regard stems from clinical trial experience, case reports and postmarketing surveillance, sources that are not, by any means, structured to provide precise data on adverse event epidemiology. For various ethical, statistical and logistical reasons, the organisation of structured clinical trials that are likely to provide substantial data on ADRs is extremely difficult. This review concentrates on current literature concerning serious and life-threatening ADRs. As with the older anticonvulsants, the majority of ADRs to newer anticonvulsants are CNS-related, although there are several that are apparently unique to some of these new drugs. Gabapentin has been reported to cause aggravation of seizures, movement disorders and psychiatric disturbances. Felbamate should only be prescribed under close medical supervision because of aplastic anaemia and hepatotoxicity. Lamotrigine causes hypersensitivity reactions that range from simple morbilliform rashes to multi-organ failure. Psychiatric ADRs and deterioration of seizure control have also been reported with lamotrigine treatment. Oxcarbazepine has a safety profile similar to that of carbamazepine. Hyponatraemia associated with oxcarbazepine is also a problem; however, it is less likely to cause rash than carbamazepine. Nonconvulsive status epilepticus has been reported frequently with tiagabine, although there are insufficient data at present to identify risk factors for this ADR. Topiramate frequently causes cognitive ADRs and, in addition, also appears to cause word-finding difficulties, renal calculi and bodyweight loss. Vigabatrin has been reported to cause seizure aggravation, especially in myoclonic seizures. There have been rare reports of other neurological ADRs to

    Full Text Available The prevalence of symptomatic adverse reactions to gluten and adherence to gluten-free diet in Latin American countries is unknown. These measurements are strongly linked to gluten-related disorders. This work aimed to estimate the prevalence of adverse reactions to oral gluten and the adherence to gluten-free diet in the adult Mexican population. To reach this aim, a self-administered questionnaire was designed and tested for clarity/comprehension and reproducibility. Then, a self-administered questionnaire-based cross-sectional study was conducted in the Mexican population. The estimated prevalence rates were (95% CI: 11.9% (9.9–13.5 and 7.8 (6.4–9.4 for adverse and recurrent adverse reactions to gluten respectively; adherence to gluten-free diet 3.7% (2.7–4.8, wheat allergy 0.72% (0.38–1.37; celiac disease 0.08% (0.01–0.45, and NCGS 0.97% (0.55–1.68. Estimated pooled prevalence of self-reported physician-diagnosis of gluten-related disorders was 0.88% (0.49–1.5, and 93.3% respondents reported adherence to gluten-free diet without a physician-diagnosis of gluten-related disorders. Symptom comparisons between those who reported recurrent adverse reactions to gluten and other foods showed statistically significant differences for bloating, constipation, and tiredness (p < 0.05. Gluten-related disorders may be underdiagnosed in the Mexican population and most people adhering to a gluten-free diet are doing it without proper diagnostic work-up of these disorders, and probably without medical/dietician advice.

    Full Text Available Antivenoms have been widely used for more than a century for treating snakebites and other accidents with poisonous animals. Despite their efficacy, the use of heterologous antivenoms involves the possibility of adverse reactions due to activation of the immune system. In this paper, alternatives for antivenom production already in use were evaluated in light of their ability to minimize the occurrence of adverse reactions. These effects were classified according to their molecular mechanism as: anaphylactic reactions mediated by IgE, anaphylactoid reactions caused by complement system activation, and pyrogenic reactions produced mainly by the presence of endotoxins in the final product. In the future, antivenoms may be replaced by humanized antibodies, specific neutralizing compounds or vaccination. Meanwhile, improvements in antivenom quality will be focused on the obtainment of a more purified and specific product in compliance with good manufacturing practices and at an affordable cost.

  10. Pharmacogenetics of idiosyncratic adverse drug reactions.

    Pirmohamed, Munir

    2010-01-01

    Idiosyncratic adverse drug reactions are unpredictable and thought to have an underlying genetic etiology. With the completion of the human genome and HapMap projects, together with the rapid advances in genotyping technologies, we have unprecedented capabilities in identifying genetic predisposing factors for these relatively rare, but serious, reactions. The main roadblock to this is the lack of sufficient numbers of well-characterized samples from patients with such reactions. This is now beginning to be solved through the formation of international consortia, including developing novel ways of identifying and recruiting patients affected by these reactions, both prospectively and retrospectively. This has been led by the research on abacavir hypersensitivity - its association with HLA-B*5701 forms the gold standard of how we need to identify associations and implement them in clinical practice. Strong genetic predisposing factors have also been identified for hypersensitivity reactions such as are associated with carbamazepine, allopurinol, flucloxacillin, and statin-induced myopathy. However, for most other idiosyncratic adverse drug reactions, the genetic effect sizes have been low to moderate, although this may partly be due to the fact that only small numbers have been investigated and limited genotyping strategies have been utilized. It may also indicate that genetic predisposition will be dependent on multiple genes, with complex interactions with environmental factors. Irrespective of the strength of the genetic associations identified with individual idiosyncratic adverse drug reactions, it is important to undertake functional investigations to provide insights into the mechanism(s) of how the drug interacts with the gene variant to lead to a phenotype, which can take a multitude of clinical forms with variable severity. Such investigations will be essential in preventing the burden caused by idiosyncratic reactions, both in healthcare and in industry

    Full Text Available Abstract Many medicines are prescribed to the paediatric population on an unlicensed or 'off-label' basis because they have not been adequately tested and/or formulated and authorized for use in appropriate paediatric age groups. Regulatory authorities also need to remind health professionals about the importance of their contribution towards the process of paediatric pharmacovigilance thanks to their reporting of adverse drug reactions. The lack of reliable data in the paediatric population is associated with specific problems including: limited availability of safety data due to the lack of clinical trials in the paediatric population; under- or over-dosing in some age groups due to the lack of pharmacokinetics data or dose-finding studies; maturation, growth and development of the paediatric population susceptible to drug-induced growth and development disorders as well as to delayed ADRs not findable in adults. Pre-marketing trials are able to provide information about the benefits of drugs but do not manage to establish a safety profile. Spontaneous reporting of suspected ADRs become an important means to promote reasonable warning signs. Therefore some ADRs may be known in their qualitative aspect and quantitative aspect only after successful marketing and use in the population during a "normal" use. When the drug is used in clinical practice in large unselected populations, epidemiological post-marketing studies are useful as they find their major confirmation in recalling all the events that occur during monitoring, with estimates of incidence of ADRs that can not be obtained by spontaneous reports. In these studies a significant role can be played by the Family Pediatricians with the participation to active pharmacovigilance projects.

    All the anomalous reactions secondary to food ingestion are defined as 'adverse reactions to food'. In 1995 the European Academy of Allergology and Clinical Immunology suggested a classification on the basis of the responsible pathogenetic mechanism; according to this classification, non-toxic reactions can be divided into 'food allergies' when they recognize immunological mechanisms, and 'food intolerances' when there are no immunological implications. The diagnostic approach to adverse reactions to food is based on accurate clinical history and objective examination, and further execution of specific tests when allergy or intolerance is suspected. The therapy for food allergies is the elimination of the food to which hypersensibility has been found; this strategy can lead, especially in pediatric age, to tolerance. If elimination diets cannot be completely performed, or if it is not possible to identify the food to eliminate, some drugs (e.g. antihistaminics, steroids, etc.) can be administered. Specific allergen immunotherapy has been recently introduced. Fundamental is food allergy prevention, especially in high-risk subjects. The therapeutic approach to secondary food intolerances is based principally on primitive disease resolution; on the other hand, some specific treatments (e.g. beta-galactosidases in lactose malabsorption) are available in case of primary intolerance.

    Late adverse reactions to intravascular iodinated contrast media are defined as reactions occurring 1 h to 1 week after contrast medium injection. They have received increasing interest over the past decade, but their prevalence remains uncertain and their pathophysiology is not fully understood. The Contrast Media Safety Committee of the European Society of Urogenital Radiology decided to review the literature and to issue guidelines. An extensive literature search was carried out and summarized in a report. Based on the available information, simple guidelines have been drawn up. The report and guidelines were discussed at the 8th European Symposium on Urogenital Radiology in Genoa. Late adverse reactions after intravascular iodinated contrast medium include symptoms such as nausea, vomiting, headache, itching, skin rash, musculoskeletal pain, and fever. A significant proportion of these reactions is unrelated to the contrast medium; however, allergy-like skin reactions are well-documented side effects of contrast media with an incidence of approximately 2%. Late reactions appear to be commoner after non-ionic dimers. The majority of late skin reactions after contrast medium exposure are probably T-cell-mediated allergic reactions. Patients at increased risk of late skin reactions are those with a history of previous contrast medium reaction and those on interleukin-2 treatment. Most skin reactions are self-limiting and resolve within a week. Management is symptomatic and similar to the management of other drug-induced skin reactions. (orig.)

    Full Text Available Medications probably are the single most important health care technology in preventing illness, disability, and death in the geriatric population. Age-related changes in drug disposition and pharmacodynamic responses have significant clinical implications; increased use of a number of medications raises the risk that medicine-related problems may occur. The relationship between increased use of drugs including the prescription medication and elderly is well established. Majority of ADRs (80% causing admission or occurring in hospital are type A reactions. Although less common occurring in elderly, type B ADRs may sometimes cause serious toxicity. Studies have correlated the integral association between old age and increased rate of adverse drug reactions arising out of confounding association between age and polypharmacy contributed by age-related changes in pharmacodynamics and pharmacokinetics at least for some medical conditions. A drug combination may sometimes cause synergistic toxicity which is greater than the sum of the risks of toxicity of either agent used alone. But, strategies to increase opportunities for identifying ADRs and related problems have not been emphasised in current international policy responses especially in India to the increase in elderly population and chronic conditions. Careful epidemiological studies that encompass large numbers of elderly drug users are required to obtain this information as increased knowledge of the frequency and cost of adverse drug reactions is important in enabling both more rational therapeutic decisions by individual clinicians and more optimal social policy.

    Adverse drug reactions (ADRs) cause considerable mortality and morbidity but no recent reviews are currently available for the European region. Therefore, we performed a review of all epidemiological studies quantifying ADRs in a European setting that were published between 1 January 2000 and 3....... These results indicate that the occurrence of ADRs in the European hospital setting-both ADRs that result in hospitalization and ADRs that occur during the hospital stay-is significant. Furthermore, the limited number of studies that were performed in the outpatient setting identify a lack of information...

    We evaluated the usefulness of individual tryptase levels and variations after adverse drug reactions in 64 patients. Our aim was to find a tool for the diagnosis of drug allergy. Thirty-seven subjects were confirmed to have drug allergy, 12 had nonsteroidal anti-inflammatory drug (NSAID) reactions, five had negative controlled drug challenges (NAAR), and 10 had symptoms after placebo intake (PLA). Serum tryptase levels greatly increased after anaphylactic shocks (2242%) and anaphylaxis (710.5%). Patients with allergic urticaria and those with idiosyncratic responses to acetylsalicylic acid (ASA) exhibited a small increase in serum tryptase (49.5% and 38.2%, respectively). In the other two groups (NAAR and PLA), no variation in this serum protease was observed. The time of appearance of the serum tryptase peak differed considerably among patients with similar clinical reactions (from 30 min to 6 h) and was independent of the latent period, severity of symptoms, or the amount of tryptase released. We conclude that serum tryptase determinations are helpful in the diagnosis of anaphylactic shock and anaphylaxis, but serial measurements may be needed to confirm mast-cell participation in milder reactions.

    Full Text Available Introduction. The surveillance on adverse reaction following immunization was aimed at recording all adverse events possibly related with vaccines. During the implementation of immunization strategy against pandemic influenza A(H1N1 in 2009, the post-marketing comprehensive surveillance was suggested to be conducted due to limited clinical experience in applying this particular vaccine and because of the fact that some vaccines had been licensed only on the basis of the data regarding their quality. Material and Methods. The passive surveillance on adverse events following immunization was conducted simultaneously with immunization campaign against pandemic influenza in the Autonomous Province of Vojvodina. Reporting of adverse events was conducted by health care service through a specially designed questionnaire Results. In the period from December 17th 2009 to February 7th 2010, of the total number of 55720 people who were vaccinated, 50433 received one dose and 5287 received two doses of vaccine. The total number of doses administered was 61007. During the observed period, some adverse reactions were recorded in 37 people, the rate of occurrence of adverse reactions being 6.6 per 10.000 vaccinated. Since the majority of patients had several symptoms and signs, the number of recorded clinical manifestations was much higher (140 than the number of patients with reactions. The dominant symptoms and signs were fever (51.4%, weakness/fatigue (48.6%, headache (40.5% and myalgia (31.5%. The reactions in the majority of patients were mild and transient. Only two patients sought medical care and one was hospitalized. Since the immunization coverage was very small, it was not possible to record rare adverse events, whose expected incidence is, anyway, very low. Conclusion. Surveillance on adverse reaction following immunization represents an important component of immunization program, especially when new vaccines are introduced. Therefore, this form

  7. Ranking Adverse Drug Reactions With Crowdsourcing

    Background: There is no publicly available resource that provides the relative severity of adverse drug reactions (ADRs). Such a resource would be useful for several applications, including assessment of the risks and benefits of drugs and improvement of patient-centered care. It could also be used to triage predictions of drug adverse events. Objective: The intent of the study was to rank ADRs according to severity. Methods: We used Internet-based crowdsourcing to rank ADRs according to severity. We assigned 126,512 pairwise comparisons of ADRs to 2589 Amazon Mechanical Turk workers and used these comparisons to rank order 2929 ADRs. Results: There is good correlation (rho=.53) between the mortality rates associated with ADRs and their rank. Our ranking highlights severe drug-ADR predictions, such as cardiovascular ADRs for raloxifene and celecoxib. It also triages genes associated with severe ADRs such as epidermal growth-factor receptor (EGFR), associated with glioblastoma multiforme, and SCN1A, associated with epilepsy. Conclusions: ADR ranking lays a first stepping stone in personalized drug risk assessment. Ranking of ADRs using crowdsourcing may have useful clinical and financial implications, and should be further investigated in the context of health care decision making.

Studies reporting ADRs from amphetamine derivates, atomoxetine, methylphenidate, and modafinil in children from birth to age 17 were included. Information about ADR reporting rates, age and gender of the child, type, and seriousness of ADRs, setting, study design, ADR assessors, authors, and funding sources were extracted.Results: The review identified 43 studies reporting ADRs associated with medicines for treatment of ADHD in clinical studies covering approximately 7000 children, the majority of 6- to 12-year-old boys, and particularly in the United States of America (USA. The most frequently reported ADRs were decrease in appetite, gastrointestinal pain, and headache. There were wide variations in reported ADR occurrence between studies of similar design, setting, included population, and type of medication. Reported ADRs were primarily assessed by the children/their parents, and very few ADRs were rated as being serious. A large number of children dropped out of studies due to serious ADRs, and therefore, the actual number of serious ADRs from use of psychostimulants is probably higher. A large number of studies were conducted by the same groups of authors and sponsored by the pharmaceutical companies manufacturing the respective medications.Conclusion: Reported ADRs from use of

    Observational study is necessary for the evaluation of drug effectiveness in clinical practice. In recent years, the use of spontaneous reporting systems (SRS) for adverse drug reactions has increased and they have become an important resource for regulatory science. SRS, being the largest and most well-known databases worldwide, are one of the primary tools used for postmarketing surveillance and pharmacovigilance. To analyze SRS, the US Food and Drug Administration Adverse Event Reporting System (FAERS) and the Japanese Adverse Drug Event Report Database (JADER) are reviewed. Authorized pharmacovigilance algorithms were used for signal detection, including the reporting odds ratio. An SRS is a passive reporting database and is therefore subject to numerous sources of selection bias, including overreporting, underreporting, and a lack of a denominator. Despite the inherent limitations of spontaneous reporting, SRS databases are a rich resource and data mining index that provide powerful means of identifying potential associations between drugs and their adverse effects. Our results, which are based on the evaluation of SRS databases, provide essential knowledge that could improve our understanding of clinical issues. PMID:27040337

    This study compared symptom reports and cardiovascular reactivity of a group of 24 individuals recruited from the community who reported a cognitive or emotional symptom caused by at least one food (food-sensitivity reporters, FSR) vs those of 15 controls (C) without a history of food, chemical, drug, or inhalant sensitivities. The main findings were: 1) FSR indicated sensitivities not only to foods, but also to environmental chemicals, drugs, and natural inhalants, as well as significantly more symptoms than C in multiple systems; 2) more FSR than C noted recent state depression and anxiety, as well as higher trait anxiety on the Bendig form of the Taylor Manifest Anxiety Scale; 3) however, on multiple regression analysis, not only depression, but also the number of sensitivities (foods, chemicals, drugs, inhalants), accounted for part of the variance in total number of symptoms (38 and 17%, respectively), whereas none of the affective measures accounted for any of the variance in total number of sensitivities over all subjects; 4) after controlling for depression and anxiety, FSR still showed a trend toward poorer performance on a timed mental arithmetic task (p = 0.16); and 5) FSR and C showed opposite patterns of heart rate change to two different stressful tasks (mental arithmetic and isometric exercise) (group by task interaction, p foods, chemicals, drugs, and inhalants) and for salient psychological stress in the expression of psychophysiological dysfunctions of FSR. As in other chronically ill populations, negative affect in food-sensitive individuals may explain greater symptom reporting, but not necessarily account for the illness itself. For either a food or a psychological stimulus to begin to elicit sensitized responses, e.g., marked physiological differences from C, FSR may require multiple, intermittent exposures spaced over 5-28 days rather than on only 1 day.

    Full Text Available Abstract Background Recent studies have shown that adverse drug reactions (ADRs are underreported. This may be particularly true of ADRs associated with complementary and alternative medicine (CAM. Data on CAM-related ADRs, however, are sparse. Objective was to evaluate the impact of an educational intervention and monitoring programme designed to improve physician reporting of ADRs in a primary care setting. Methods A prospective multicentre study with 38 primary care practitioners specialized in CAM was conducted from January 2004 through June 2007. After 21 month all physicians received an educational intervention in terms of face-to-face training to assist them in classifying and reporting ADRs. The study centre monitored the quantity and quality of ADR reports and analysed the results. To measure changes in the ADR reporting rate, the median number of ADR reports and interquartile range (IQR were calculated before and after the educational intervention. The pre-intervention and post-intervention quality of the reports was assessed in terms of changes in the completeness of data provided for obligatory items. Interrater reliability between the physicians and the study centre was calculated using Cohen's kappa with a 95% confidence interval (CI. We used Mann Whitney U-test for testing continuous data and chi-square test was used for categorical data. The level of statistical significance was set at P Results A total of 404 ADRs were reported during the complete study period. An initial 148% increase (P = 0.001 in the number of ADR reports was observed after the educational intervention. Compared to baseline the postinterventional number of ADR reportings was statistically significant higher (P P Conclusion The results of the present study demonstrate that an educational intervention can increase physician awareness of ADRs.

Method: After an informed consent, 130 randomly chosen patients using pharmacy services from eight different health units in Riberão Preto - São Paulo (Brazil were interviewed. To gather socioeconomic, clinical data and ADR, an structured questionnaire was used. The latter were analyzed regarding their seriousness, frequency, causality and preventability. Results: All surveyed patients reported at least one ADR to amitriptyline, being doubtful (4%, possible (44% and probable (52%. From probable/possible, 29% were reported as moderate/serious, and among them, 67% were frequent. 79% of total ADR were considered as preventable. 5 more cited symptoms (29.5% were: dry mouth or taste disturbances, drowsiness, orthostatic hypotension and weakness. Conclusions: Reported amitriptylin ADRs could have been prevented or reduced their seriousness, or, at least, advised when occurring, because they may produce other drug-related problems, non-compliance or discomfort. Patients should be taken into account as ADR information sources, improving physician-patient relationship and their quality of life by improving medical care.

    Full Text Available Various adverse cutaneous reactions may occur as a result of exposure to wood dust or solid woods. These include allergic contact dermatitis, irritant contact dermatitis and, more rarely, contact urticaria, photoallergic and phototoxic reactions. Also cases of erythema multiforme-like reactions have been reported. Contact dermatitis, both allergic and irritant, is most frequently provoked by exotic woods, e.g. wood of the Dalbergia spp., Machaerium scleroxylon or Tectona grandis. Cutaneous reactions are usually associated with manual or machine woodworking, in occupational setting or as a hobby. As a result of exposure to wood dust, airborne contact dermatitis is often diagnosed. Cases of allergic contact dermatitis due to solid woods of finished articles as jewelry or musical instruments have also been reported. The aim of the paper is to present various adverse skin reactions related to exposure to woods, their causal factors and sources of exposure, based on the review of literature.

    Full Text Available Abstract Introduction Parkinsonism puts a high direct cost burden on both patient and caregiver. Several reports of drug-induced parkinsonism have been published, but to the best of our knowledge, there has not been any report of quinine or halothane inducing parkinsonism. Case presentation We describe two cases of parkinsonism possibly caused by adverse drug reaction to quinine in a 29-year-old black Nigerian woman and to halothane in a 36-year-old black Hausa (Nigerian man who received it as general anaesthesia for appendicectomy in our teaching hospital. Conclusion These are two unusual cases of parkinsonism caused by adverse drug reactions to high-dose quinine and to halothane as general anaesthesia. We consider that these two cases are important in bringing this potential side-effect to the attention of both pharmacologists and primary care physicians as these are two of the most commonly used medications in our clinics. We conclude that parkinsonism should be included among the adverse drug reactions to high-dose quinine and halothane general anaesthetic.

    Licorice is a traditional Chinese medicine commonly used in clinic. The products,what contain licorice or licorice extract, has early been involved in the field of cosmetics except for the field of pharmaceuticals and food. Consequently, the reporting on adverse reactions induced by licorice preparations are more frequent. Based on the clinical data of licorice preparations adverse reactions, we described the characteristics of the licorice-related adverse reactions, and proposed specific measures to reduce the incidence of adverse reactions, provided a reference for the rational use of licorice preparations.

    The objective of this study was to evaluate the clinical safety of intravenous gadolinium-based contrast media used in patients who underwent MRI at a single institution. Acute adverse reactions to intravenous gadolinium-based contrast media used for MRI at the Princess Margaret Hospital, Hong Kong, SAR, from January 1999 to November 2004 were recorded in an incidence log book. The medical records of patients' demographics were retrospectively reviewed and the nature, frequency and severity of the adverse reactions were investigated and documented. The incidence of acute adverse reactions to intravenous gadolinium-based contrast media was 0.48% (45 patients with 46 adverse reactions). The severity of these adverse reactions were 96% mild, 2% moderate (one patient developed shortness of breath that required oxygen supplementation and intravenous steroidal management) and 2% severe (one patient developed an anaphylactoid reaction, but successfully recovered through timely resuscitation). No patients were recorded as having contrast extravasation and none died as a result of any adverse reaction. Among the 45 patients who developed adverse reactions, three patients (6.7%) had prior adverse reactions to iodinated contrast media, three (6.7%) had prior reactions to a different gadolinium-based contrast agent, one (2%) had asthma and nine (20%) had a history of drug/food allergy. Overall, 41% of the adverse reactions were not documented in the final MRI report or the clinical medical records. Gadolinium-based contrast media are safe and well tolerated by the vast majority of patients. In our study, the adverse reaction rate (0.48%) and the incidence of severe anaphylactoid reaction (0.01%) concur with those reported in the literature. Although most of the symptoms are mild and transient, these adverse reactions must be accurately documented and managed. PMID:16632615

    2015-07-01

    Isotretinoin is the strongest, most effective oral treatment for patients with severe acne vulgaris, with remission rates of 89% and higher. Because of its potency, isotretinoin causes many adverse reactions. This article reviews common and severe adverse reactions to isotretinoin and how providers can best manage these reactions. Because of inconclusive research on the correlation between isotretinoin and depression and irritable bowel syndrome, providers should ask patients about symptoms monthly. Prescribing micronized isotretinoin and starting at the lowest dose with gradual upward titration also can help reduce the incidence of adverse reactions.

    Full Text Available Background: Adverse Drug Reactions (ADRs are one of the leading causes of morbidity and mortality and contribute to excessive health care costs. Detection and reporting of ADRs could decrease these consequences. The present study was designed to assess the Knowledge, Attitude and Practice (KAP of pharmacy students towards ADRs monitoring and reporting.Methods: A questionnaire was prepared to investigate the Knowledge, Attitude and Practice (KAP of pharmacy students regarding ADR reporting. The questionnaire consisting of 17 questions (7 questions on knowledge, 5 on attitudes and 5 on practice were given to pharmacy students randomly.Results: A total of 71 respondents participated in the study. 70% of participants had favorable general knowledge about ADRs but more than 60% of their professional knowledge was not satisfying. 60% of respondent believed that educational intervention will improve participating of health care professional in ADRs reporting. 63% of respondent observed ADRs cases but about 95% of them had never reported an ADR.Conclusion: In overall, pharmacy students have poor knowledge, attitude and practice towards ADRs reporting and pharmacovigilance. This suggests the need of suitable changes in the undergraduate teaching curriculum and additional training among the students regarding ADRs.

  16. Epidemiology and prevention of adverse drug reactions in the elderly

    Institute of Scientific and Technical Information of China (English)

    Lexin WANG

    2005-01-01

    Many studies have demonstrated a correlation between increasing age and adverse drug reactions. This increased risk is related to aged-related changes in pharmacokinetics and pharmacodynamics. In addition, chronic illnesses such as congestive heart failure, coronary artery disease and hypertension are more prevalent in the elderly who also have an increased risk of diabetes, arthritis and cancer. Consequently elderly patients are often treated with multiple medications, which may cause drug interactions and adverse drug reactions. Adequate undergraduate training in clinical pharmacology and continued professional development in evidence-based therapeutics will undoubtedly reduce inappropriate prescribing and improve the quality of medications. Good communications between physicians and patients are also critically important in avoidance or prevention of adverse drug reactions in the elderly.

    Full Text Available The use of cardiovascular drugs is related to the development of adverse drug reactions (ADRs in about 24% of the patients in the Cardiovascular Care Unit. Here, we evaluated the ADRs in patients treated with antihypertensive drugs. The study was conducted in two phases: In the first phase, we performed a retrospective study on clinical records of Clinical Divisions (i.e., Internal Medicine Operative Unit and Geriatric Operative Unit from January 1, 2012 to December 31, 2012. Moreover from January 1, 2013 to March 30, 2013 we performed a prospective study on the outpatients attending the Emergency Department (ED of the Pugliese-Ciaccio Hospital of Catanzaro, by conducting patient interviews after their informed consent was obtained. The association between a drug and ADR was evaluated using the Naranjo scale. We recorded 72 ADRs in the Clinical Divisions and six in the ED, and these were more frequent in women. Using the Naranjo score, we showed a probable association in 92% of these reactions and a possible association in 8%. The most vulnerable age group involved in ADRs was that of the elderly patients. In conclusion, our results indicate that antihypertensive drugs may be able to induce the development of ADRs, particularly in elderly women receiving multiple drug treatment. Therefore, it is important to motivate the healthcare providers to understand their role and responsibility in the detection, management, documentation, and reporting of ADRs, as also all the essential activities for optimizing patient safety.

    Full Text Available Epilepsy is one of the most common neurologic disorders in dogs and life-long treatment with antiepileptic drugs (AED is frequently required. Adverse events of antiepileptic drugs targeting the skin are only rarely reported in veterinary medicine and the true incidence and spectrum of cutaneous reactions in epileptic dogs remains unknown. In this study we hypothesized that cutaneous reactions commonly occur in epileptic dogs and are related to AED treatment. A retrospective case review of 185 dogs treated for epilepsy identified 20.0% with simultaneous appearance of dermatologic signs. In a subsequent prospective case investigation (n=137 we identified newly appearing or distinct worsening of skin lesions following initiation of antiepileptic drug therapy in 10.9% of dogs treated for epilepsy (95% CI 6.8- 17.7%. Cutaneous lesions were classified as probably drug-induced in 40.0% of these cases. Patch-testing and intradermal testing was further investigated as potential diagnostic methods to confirm antiepileptic drug hypersensitivity. They were of high specificity but sensitivity and positive predictive value appeared inappropriate to recommend their routine use in clinical practice.

    In social dilemmas, cooperation among randomly interacting individuals is often difficult to achieve. The situation changes if interactions take place in a network where the network structure jointly evolves with the behavioral strategies of the interacting individuals. In particular, cooperation can be stabilized if individuals tend to cut interaction links when facing adverse neighborhoods. Here we consider two different types of reaction to adverse neighborhoods, and all possible mixtures between these reactions. When faced with a gloomy outlook, players can either choose to cut and rewire some of their links to other individuals, or they can migrate to another location and establish new links in the new local neighborhood. We find that in general local rewiring is more favorable for the evolution of cooperation than emigration from adverse neighborhoods. Rewiring helps to maintain the diversity in the degree distribution of players and favors the spontaneous emergence of cooperative clusters. Both propert...

    2014-01-01

    Multidrug antituberculosis regimen is associated with diverse clinical patterns of cutaneous adverse drug reactions (CADR), ranging from mild and moderate such as pruritus, maculopapular exanthems, lichenoid eruptions, fixed drug eruptions and urticaria to severe and even life threatening ones like acute generalized exanthematous pustulosis (AGEP), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). These adverse reactions to antituberculosis drugs are commonly observed adverse events. This is of particular importance for high HIV prevalence settings and developing countries where tuberculosis is common infection resulting in higher occurrence rate of these reactions. There is still significant heterogenity in definition and classification of CADR, as well as diversity in treatment modalities following adverse reactions and rechallenge management. The aim of this review is to discuss clinical presentation, occurrence of CADR caused by antituberculosis drugs, to identify risk factors for intolerance of the standard therapy as well as to draw attention to importance of multi-disciplinary approach, early detection, prompt diagnosis and in time management of antituberculosis drugs associated CADR. CADR can cause significant treatment interruption and alteration, resulting in increased risk of treatment failure, drug resistance, relapses and increased risk of complications including even lethal outcome. Finally, it can be concluded that it is of great importance to identify the best possible treatment and preventive regimens in order to enable continuity of the antituberculosis therapy to the full extent.

    Full Text Available Latex allergy has become an occupational hazard among healthcare workers. Atopy, intensity and duration of exposure have been recognized as predisposing factors for latex sensitization. Frequency of sensitization varies among countries. So we decided to investigate the prevalence of latex sensitization and potential risk factors among healthcare workers in a general hospital. In a cross sectional study by distributing a questionnaire among 876 employees of a general hospital, we investigated the prevalence of latex allergy and the potential risk factors for latex sensitization. We collected information about occupational history, including specific tasks performed, time of first exposure to latex, number of pairs of gloves used, and duration of weekly exposure. We also investigated the interval between first exposure and onset of symptoms. We asked about pre-existing rhinoconjuctivitis, asthma, atopic and contact dermatitis, hay fever, autoimmune diseases, and food allergies. This survey documented a high prevalence of adverse reaction to all latex containing materials (52.5%. 37.7% of responder had adverse reaction to latex gloves. The highest prevalence of adverse reaction to all latex containing materials was found in the surgical operating room, followed by emergency unit and internal medicine wards. According to this study, frequency of adverse reaction to latex was high among health care workers. This may be due to relatively low response rate, low quality of latex products in Iran, and the method of measurement. Whenever, the need for implementing prevention program, using latex-free methods and training of employees to reduce adverse reaction to latex is apparent.

  6. An overview on adverse drug reactions to traditional Chinese medicines.

    Chan, Kelvin; Zhang, Hongwei; Lin, Zhi-Xiu

    2015-10-01

    The safe use of Chinese materia medica (CMM) and products in traditional Chinese medicine (TCM) practice conventionally relies on correct pharmacognostic identification, good agricultural and manufacturing practices based on pharmacopoeia standards and rational/correct CMM combinations with TCM-guided clinical prescribing. These experience-based principles may not absolutely ensure safety without careful toxicological investigations when compared with development of new pharmaceutical drugs. Clinically observed toxicity reports remain as guidance for gathering toxicological evidence, though essential as pharmacovigilance, but are considered as late events for ensuring safety. The overview focuses on the following factors: global development of TCM that has affected conventional healthcare; examples of key toxic substances in CMM; reported adverse drug reactions (ADRs) consequential to taking CMM and TCM products; and proposals on rational approaches to integrate the knowledge of biomedical science and the principles of TCM practice for detecting early ADRs if both TCM products and orthodox drugs are involved. It is envisaged that good control of the quality and standards of CMM and proprietary Chinese medicines can certainly reduce the incidence of ADRs in TCM practice when these medications are used.

    @@ 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, although it is used in patentpreparations, 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 one and a half to two hours, symptoms similar to digitalis toxicity appear, such as nausea, which is often the first indicator of toxicity, anorexia, vomiting, visual disturbances relating to colour vision, headache, weakness, psychosis, arrythmias, slowing of heart rate, AV block, and asystole.Severe cardiac damage is the major cause of death. It has al so been known to promote contraction of the uterus; therefore it should not be used in pregnant women(40,41). One paper has reported 27 cases intoxicated by Liushenwan, inclu ding one fatal(13).

    Full Text Available Objectives: Fragmented blood transfusion services along with an unmotivated blood donation culture often leads to blood shortage. Donor retention is crucial to meet the increasing blood demand, and adverse donor reactions have a negative impact on donor return. The aim of this study was to estimate adverse donor reactions and identify any demographic association.   Methods: We conducted a prospective study between January 2011 and December 2013. A total of 41,759 healthy donors were enrolled. Professionally trained donor attendants drew blood and all donors were observed during and following donation for possible adverse events for 20 minutes. Blood donors were asked to report if they suffered from any delayed adverse consequences.   Results: Out of 41,759 blood donors, 537 (1.3% experienced adverse reactions. The incidence was one in every 78 donations. The mean age of donors who experienced adverse events was 26.0±6.8 years, and all were male. Out of 537 donors, 429 (80% developed vasovagal reaction (VVR, 133 (25% had nausea, 63 (12% fainted, 35 (6% developed hyperventilation, 9 (2% had delayed syncope, and 9 (2% developed hematoma. Arterial prick, nerve injury, cardiac arrest, and seizures were not observed. Donors aged less than < 30 years and weighing < 70 kg were significantly associated with VVR, hyperventilation, and nausea (p < 0.005. Undergraduates and Urdu speaking donors also had a significant association with fainting and nausea, respectively (p < 0.05.   Conclusion: The prevalence of adverse events was low at our tertiary center. A VVR was the predominant adverse reaction and was associated with age and weight. Our study highlights the importance of these parameters in the donation process. A well-trained and experienced phlebotomist and pre-evaluation counseling of blood donors could further minimize the adverse reactions.

    The purpose of the study is to examine the incidence of adverse reactions caused by non-ionic contrast media in selected patients after desensitization treatment and to evaluate the safety profile of organ iodine contrast media (i.c.m.) in a multistep prevention protocol. In a population of 2000 patients that had received a CT scan, 100 patients with moderate/high risk for adverse reactions against iodinated contrast agents followed a premedication protocol and all adverse reactions are reported and classified as mild, moderate or severe. 1.7 percent of the pre-treated patients reported a mild, immediate type reaction to iodine contrast; of these five patients with allergy 0.71 percent had received iomeprol, 0.35 percent received ioversol and 0.71 percent received iopromide. The incidence of adverse reactions was reported to be higher (4 out of 5 patients) among those that referred a history of hypersensitivity against iodinated i.c.m. Although intravenous contrast materials have greatly improved, especially in terms of their safety profile, they should not be administered if there isn't a clear or justified indication. In conclusion, even if we know that the majority of these reactions are idiosyncratic and unpredictable we propose, with the aim of improving our knowledge on this subject, a multicenter study, based on skin allergy tests (prick test, patch test, intradermal reaction) in selected patients that have had previous experiences of hypersensitivity against parenteral organ iodine contrast media.

    Adverse reactions and toxicity: Amygdalin is the main toxic constituent, which can be decomposed to hydrocyanic acid. Toxicity is dose related; 55--60 pieces of Xing ren, containing approximately 1.8 g of amygdalin, is often the fatal dose in adults. Two hours after administration, the first symptoms often appear, such as a bitter taste in mouth accompanied with oversalivation, nausea, vomiting, abdominal pain, diarrhea, headache, dizziness, palpitations, dyspnea, cyanosis, which may lead to coma and death due to respiratory arrest .

    Adverse drug reactions (ADRs) are common in older adults, with falls, orthostatic hypotension, delirium, renal failure, gastrointestinal and intracranial bleeding being amongst the most common clinical manifestations. ADR risk increases with age-related changes in pharmacokinetics and pharmacodynamics, increasing burden of comorbidity, polypharmacy, inappropriate prescribing and suboptimal monitoring of drugs. ADRs are a preventable cause of harm to patients and an unnecessary waste of health...

    Adverse reactions after intravascular administration of iodine contrast media are common and prophylactic regiments consisting of the use of steroids and low osmolality contrast media are highly effective in significantly decreasing the adverse reactions rate. The same type of contrast media are also used for opacification of the biliary tree and the pancreatic duct at the time of endoscopic retrograde cholangiopancreatography (ERCP). Systemic absorption of contrast media after ERCP routinely occurs. Although the adverse reaction rate appears to be very low the exact incidence remains unknown due to the retrospective nature of all reports. Despite the lack of formal recommendations, numerous prophylactic regiments are routinely used prior to ERCP in patients with history of prior reaction to intravascular contrast media. Moreover, the use of prophylaxis has even expanded to patients with no prior reaction to intravascular contrast media who are somehow perceived to be at increase risk (e.g. shellfish allergy). Recently, the first large scale prospective study reported exceedingly low incidence of adverse reaction to high oslmolality iodine-containing contrast media administered at the time of ERCP done without prophylactic premedication even in patients considered to be at the highest risk (prior severe reaction to intravascular contrast media administration). These data suggest that the use of prophylactic regiments prior to ERCP appears to be unnecessary. PMID:19275689

    A big challenge in pharmacology is the understanding of the underlying mechanisms that cause drug-induced adverse reactions (ADRs), which are in some cases similar to each other regardless of different drug indications, and are in other cases different regardless of same drug indications. The FDA Adverse Event Reporting System (FAERS) provides a valuable resource for pharmacoepidemiology, the study of the uses and the effects of drugs in large human population. However, FAERS is a spontaneous reporting system that inevitably contains noise that deviates the application of conventional clustering approaches. By performing a biclustering analysis on the FAERS data we identified 163 biclusters of drug-induced adverse reactions, counting for 691 ADRs and 240 drugs in total, where the number of ADR occurrences are consistently high across the associated drugs. Medically similar ADRs are derived from several distinct indications for use in the majority (145/163=88%) of the biclusters, which enabled us to interpret the underlying mechanisms that lead to similar ADRs. Furthermore, we compared the biclusters that contain same drugs but different ADRs, finding the cases where the populations of the patients were different in terms of age, sex, and body weight. We applied a biclustering approach to catalogue the relationship between drugs and adverse reactions from a large FAERS data set, and demonstrated a systematic way to uncover the cases different drug administrations resulted in similar adverse reactions, and the same drug can cause different reactions dependent on the patients' conditions.

    2009-10-14

    The incidence of acute iodine contrast media reactions, appearing within the first hour after the procedure, is low but clinically important due to their daily use. Previous adverse reactions to iodinated contrast media, asthma and a history of allergic reaction are the most recognized risk factors, but the identification of patients at risk remains difficult. The efficacy of preventive measures such as corticosteroid and/or antihistaminic administration rests on low-level evidence. Practical recommendations are presented in this article. Rather than relying on the sole administration of a premedication, the importance of other measures must be stressed: assessing the relevance of the indication to the radiologic exam, use of low osmolarity contrast media, and ensuring a proper monitoring of the patient during and after the procedure.

    Full Text Available BACKGROUND: There is little research on parents' experiences of suspected adverse drug reactions in their children and hence little evidence to guide clinicians when communicating with families about problems associated with medicines. OBJECTIVE: To identify any unmet information and communication needs described by parents whose child had a suspected adverse drug reaction. METHODS: Semi-structured qualitative interviews with parents of 44 children who had a suspected adverse drug reaction identified on hospital admission, during in-patient treatment or reported by parents using the Yellow Card Scheme (the UK system for collecting spontaneous reports of adverse drug reactions. Interviews were conducted face-to-face or by telephone; most interviews were audiorecorded and transcribed. Analysis was informed by the principles of the constant comparative method. RESULTS: Many parents described being dissatisfied with how clinicians communicated about adverse drug reactions and unclear about the implications for their child's future use of medicines. A few parents felt that clinicians had abandoned their child and reported refusing the use of further medicines because they feared a repeated adverse drug reaction. The accounts of parents of children with cancer were different. They emphasised their confidence in clinicians' management of adverse drug reactions and described how clinicians prospectively explained the risks associated with medicines. Parents linked symptoms to medicines in ways that resembled the established reasoning that clinicians use to evaluate the possibility that a medicine has caused an adverse drug reaction. CONCLUSION: Clinicians' communication about adverse drug reactions was poor from the perspective of parents, indicating that improvements are needed. The accounts of parents of children with cancer indicate that prospective explanation about adverse drug reactions at the time of prescription can be effective. Convergence

    Objective: To discuss the modes for smooth progress of ADR monitoring under the new Measures for the Administration of Adverse Drug Reaction Report and Monitoring. Method: Work modes for ADR monitoring in drug manufacturers were explored by explaining the new Measures and analyzing current state and constrains. Result and Conclusion: As there is a larger gap between the requirements of new Measures and current status, it is difficult for drug manufacturers to meet all the requirements in short term. Therefore, drug manufacturers are suggested to gradually complete ADR monitoring under the mode of one platform and four expansions, and thereby finally meeting the requirements of new Measures and fulfilling their duties and missions.%目的:探讨药品生产企业在《药品不良反应报告和监测管理办法》(新《办法》)下顺利开展ADR监测工作的模式.方法:通过对新《办法》解读、现状及制约因素分析,探索生产企业ADR监测工作开展模式.结果与结论:生产企业在短期内一步到位完全按照新《办法》要求开展ADR监测工作与现状跨度较大,可以通过一“平台”四“拓展”的模式,分块逐步突破,开展ADR监测工作,最终完全达到新《办法》的要求,履行主体地位的责任和使命.

    Full Text Available Possibly still are health professionals that when hearing about adverse drug reactions only think in cutaneous rash, blood dyscrasias, anaphylactic shock and congenital malformations. The mentioned adverse effects are real, but relatively infrequent. Furthermore, are unexpected, not related with the pharmacological mechanism of action, unpredictable and dose independent. These adverse drug reactions are like a therapeutic lottery, depending on «luck».However, when the pharmacological pathology resulting in medical care is analyzed, the perspective is very different. For instance, the predominant adverse drug reactions in emergency wards are those related with the pharmacological mechanism of action: severe hemorrhage due to anticoagulant and antiplatelet drugs; renal insufficiency and hyperkalemia by inhibitors of the renin-angiotensin axis; hyponatremia, fells and fractures by SSRI antidepressants, digitalis intoxication… These are relatively common pathologies, expectable, dose-related, and favored by patient comorbidity, preventable in many cases if the dose would have carefully individualized, if the patient complied better with the instructions (in case the patient understood the information or if a more carefully clinical surveillance were performed.A review of the literature reminds us other pathologies attended in other assistance levels, for example:- Breast cancer attributable to the hormone replacement therapy (HRT: three to four additional cases per 1.000 women treated during 5 years, this is translated in thousands of additional cases of breast cancer according to the sales data of these products between the years 1993 to 2003.

    Full Text Available Background. Antituberculosis multidrug regimens have been associated with increased incidence of adverse drug reactions (ADRs. This study aimed to determine the incidence and associated factors of ADRs due to antituberculosis therapy. Methods. This is a retrospective cross-sectional study on tuberculosis patients who were treated in tuberculosis clinics in Markazi province in Iran. The information contained in the medical files was extracted and entered into the questionnaire. Data was descriptively analyzed by using statistical package for social sciences (SPSS 18. Results. A total of 940 TB patients of 1240 patients’ medical records available in 10 medical offices were included in this study. Of the 563 ADRs found in this study, 82.4% were considered minor reactions and 17.6% were major reactions. No death from antituberculosis ADR was observed. We found that the risk of major ADRs was higher in females (P  value=0.0241, age >50 y (P  value=0.0223, coinfection with HIV (P  value=0.0323, smoking (P  value=0.002, retreatment TB (P  value=0.0203, and comorbidities (P  value=0.0005. Conclusions. This study showed that severe side effects of anti-TB drugs are common in patients who have risk factors of ADRs and they should be followed up by close monitoring.

    Full Text Available In this study, we assessed the adverse reactions to influenza vaccination in HIV- infected individuals. From November 2006 to January 2007, a total of 203 HIV-infected persons were recruited. Demographic data were collected. Subjects were evaluated 48 h and 15 days after vaccination for symptoms and significant health events as possible side effects. Participants were instructed to measure their temperature in the morning and evening for 2 days post-immunization and to assess injection site and systemic adverse reactions. 80.3% of the subjects were male. The mean age of the subjects was 36.9±7.9 years. Local and systemic reactions were reported by 61 (30% and 62 (30.5% persons, respectively. The most common adverse reactions to the influenza vaccine included skin redness (37 cases, induration (32 cases, and pain (55 cases as local reac-tions, and fever (22 cases, myalgia (46 cases, headache (12 cases and weakness (35 cases as general reactions. 1.4 % of the subjects had fever over 38.5 ºC. There were significant associations between myalgia and flushing with CD4 counts (P<0.05. We found no relationship between ad-verse reactions and sex, history of smoking, allergy, alcohol, and drug usage, stage of HIV infec-tion, anti-retroviral therapies, anti-TB medication and previous vaccination. We concluded that inactivated influenza vaccine administered in HIV-infected adults did not result in potential ad-verse events in this study population.

    2016-01-01

    Predicting novel drug side-effects, or Adverse Drug Reactions (ADRs), plays an important role in the drug discovery process. Existing methods consider mainly the chemical and biological characteristics of each drug individually, thereby neglecting information hidden in the relationships among drugs. Complementary to the existing individual methods, in this paper, we propose a novel network approach for ADR prediction that is called Augmented Random-WAlk with Restarts (ARWAR). ARWAR, first, applies an existing method to build a network of highly related drugs. Then, it augments the original drug network by adding new nodes and new edges to the network and finally, it applies Random Walks with Restarts to predict novel ADRs. Empirical results show that the ARWAR method presented here outperforms the existing network approach by 20% with respect to average Fmeasure. Furthermore, ARWAR is capable of generating novel hypotheses about drugs with respect to novel and biologically meaningful ADR.

    Full Text Available Introduction. An adverse event after immunization is a medical incident following the administration of vaccine, which can be connected with vaccine usage. This event could be a reaction to a vaccine component or lapse in vaccine handling, transport and storage or coincidental event. The assessment of severity of this reaction and the decision about prospective permanent contraindications for futher immunization are to be made by the regional expert team for permanent contraindications. This is regulated by low. Case report. A series of adverse events after immunization in three children of a single family is reported. As regulated by law, all three children were vaccinated with different vaccines, from 2007. to 2010. Although the recorded events were diverse by their nature, way of clinical manifestation and severity they all required hospitalization. In addition to being siblings, the three children had the same atopic diseases in their personal and family anamnesis. All adverse events were explored including allergological/immunological tests. Thanks to the good cooperation of involved general practicioners, pediatricians, members of expert team for permanent contraindications and clinicians, two of three children received the full series of vaccines in optimal time. Discussion. Decision making about futher immunization of children with adverse event after vaccine administration depends on the nature and severity of developed medical condition, results of medical exploration, existing immunity and personal risk of getting disease and subsequent complications. Conclusion. Bearing in mind the significance of immunization for personal and collective immunity, good cooperation of all physicians and experts involved in each single case of adverse event is required.

    Purpose Brentuxiumab vedotin (BV) is an anti-CD30 monoclonal antibody-drug conjugate approved in 2011 for treating anaplastic large cell and Hodgkin lymphomas. The product label indicates that three BV-treated patients developed progressive multifocal leukoencephalopathy (PML), a frequently fatal JC-virus induced central nervous system infection. Prior immunosuppressive therapy and compromised immune systems were postulated risk factors. We report 5 patients who developed BV-associated PML, including two immunocompetent patients. Patients Case information was obtained from clinicians (four patients) or a Food and Drug Administration database (one patient). Results All five patients had lymphoid malignancies. Two patients with cutaneous T-cell lymphomas had not previously received chemotherapy. PML developed after a median of three BV doses (range, 2 to 6) and within a median of 7 weeks following BV initiation (range, 3 to 34 weeks). Presenting findings included aphasia, dysarthria, confusion, hemiparesis, and gait dysfunction; JC virus in cerebrospinal fluid (two patients), or CNS biopsy (three patients); and brain MRI scans with white matter abnormalities (five patients). Four patients died a median of 8 weeks (range, 6 to 16 weeks) after PML diagnosis. The sole survivor developed immune reconstitution inflammatory syndrome. Conclusion PML can develop after a few BV doses and within weeks of BV initiation. Clinicians should be aware of this syndrome, particularly when neurologic changes develop following BV initiation. The decision to administer BV to patients with indolent cutaneous lymphomas should be based on consideration of risk-benefit profiles and of alternative options. PMID:24771533

    Full Text Available Untoward reactions to cosmetics, toiletries, and topical applications are the commonest single reason for hospital referrals with allergic contact dermatitis. In most cases, these are only mild or transient and most reactions being irritant rather than allergic in nature. Various adverse effects may occur in the form of acute toxicity, percutaneous absorption, skin irritation, eye irritation, skin sensitization and photosensitization, subchronic toxicity, mutagenicity/genotoxicity, and phototoxicity/photoirritation. The safety assessment of a cosmetic product clearly depends upon how it is used, since it determines the amount of substance which may be ingested, inhaled, or absorbed through the skin or mucous membranes. Concentration of ingredients used in the different products is also important. Various test procedures include in vivo animal models and in vitro models, such as open or closed patch test, in vivo skin irritation test, skin corrosivity potential tests (rat skin transcutaneous electrical resistance test, Episkin test, eye irritation tests (in vivo eye irritancy test and Draize eye irritancy test, mutagenicity/genotoxicity tests (in vitro bacterial reverse mutation test and in vitro mammalian cell chromosome aberration test, and phototoxicity/photoirritation test (3T3 neutral red uptake phototoxicity test. Finished cosmetic products are usually tested in small populations to confirm the skin and mucous membrane compatibility, and to assess their cosmetic acceptability.

    Full Text Available Toxic epidermal necrolysis (TEN is a rare but serious is a rare but potentially life-threatening condition. It is primarily a cutaneous reaction to various precipitating agents, characterized by wide spread erythema and detachment of the epidermis from the dermis. Among the various cutaneous adverse drug reactions, TEN occupy a primary place in terms of mortality. In TEN large sheets of skin are lost from the body surface, thereby decreasing the protecting function of the skin, which results in complications. Usually, TEN is self-limited in absence of complications. If complicated by sepsis, there will be increased chances of mortality. The main treatment would be cessation of the causative drug and early admission of the patient for supportive care and minimizing the occurrence of complications. The present articles reviews the etiology, pathophysiology, differential diagnosis and treatment protocol, with a case of TEN occurrence in a child of 4 years age after consuming phenytoin syrup for febrile convulsions.

    Searching the internet for an explaination of recurring symptoms, many people come across the so-called histamine intolerance disorder. Also many practitioners like to diagnose this disorder without making sure that reproducibility, a prerequisite for an adverse reaction, is present. Consequently, presumably affected persons are often advised to follow a low-histamine diet. Depending on the source of information, these diets often avoid a huge variety of foods containing more or less histamine, which has a considerable impact on patient quality of life. While most persons benefit from such a diet in the beginning - this might be due to the change in dietary habits or the expectation of symptom improvement by dieting - in the long run the expected loss of symptoms will not happen. Underlying a diminished capacity for histamine degradation, the lack of partial or complete symptom improvement might be due to the fact that endogenous histamine release is responsible for reactions. The role of ingested histamine is discussed controversially. However, it is more than obvious that the histamine content of a certain food alone is not enough to predict its tolerance.If histamine intolerance is suspected, an individual diagnostic and therapeutic procedure is mandatory in order to minimize avoidance and to preserve a high quality of life. Ideally this is done in a close cooperation between allergologists and nutritionists/dieticians. PMID:27177895

    Full Text Available OBJECTIVE: CYP2C9 is a major enzyme in human drug metabolism and the polymorphism observed in the corresponding gene may affect therapeutic outcome during treatment. The distribution of variant CYP2C9 alleles and prevalence of phenytoin adverse reactions were hereby investigated in a population of patients diagnosed with epilepsy. METHOD: Allele-specific PCR analysis was carried out in order to determine frequencies of the two most common variant alleles, CYP2C9*2 and CYP2C9*3 in genomic DNA isolated from 100 epileptic patients. We also analyzed the frequency of phenytoin adverse reactions among those different genotypes groups. The data was presented as mean±standard deviation. RESULTS: The mean age at enrollment was 39.6±10.3 years (range, 17-72 years and duration of epilepsy was 26.5±11.9 years (range 3-48 years. The mean age at epilepsy onset was 13.1±12.4 years (range, 1 month-62 years. Frequencies of CYP2C9*1 (84%, CYP2C9*2 (9% and CYP2C9*3 (7% were similar to other published reports. Phenytoin adverse reactions were usually mild and occurred in 15% patients, without correlation with the CYP2C9 polymorphism (p=0.34. CONCLUSION: Our findings indicate an overall similar distribution of the CYP2C9 alleles in a population of patients diagnosed with epilepsy in the South of Brazil, compared to other samples. This sample of phenytoin users showed no drug related adverse reactions and CYP2C9 allele type correlation. The role of CYP2C9 polymorphism influence on phenytoin adverse reaction remains to be determined since some literature evidence and our data found negative results.

  1. Consideration of Adverse Reaction to MDCT Contrast Media

    International Nuclear Information System (INIS)

    In this experiment, we investigated 82 patients who suffered adverse reactions due to contrast medium. We selected the subjects out of 21,178 people who had an intravenous injection of contrast medium to undergo MDCT examination at one university hospital in Busan in 2007. As a result, the largest groups of the patients were as follows. 52.4% of the patients were male when classify by gender; 28.0% of the patients were 50's by age; 45% of the patients got when it was spring(April and March); 75.6% of the patients had a side effects when the speed of injection is 2.5 mL/sec; 58.5% of the patients were suffered when the volume of injected contrast medium is over 130 mL. Urticaria was the main symptom of side effect as 26.8%. And the main treatment for the effect was alleviating the symptoms before making patients to return home. Thus, practical preventive measures are needed as follows: use the OCS system to observe warning signs at risky patients, secure warming spaces for patients to cope with season changing, prepare enough emergency kits for the patients in danger, and establish CPR call systems, explain the risk of contrast medium and get agree about using contrast medium.

  2. Predicting risk of adverse drug reactions in older adults.

    Lavan, Amanda Hanora; Gallagher, Paul

    2016-02-01

    Adverse drug reactions (ADRs) are common in older adults, with falls, orthostatic hypotension, delirium, renal failure, gastrointestinal and intracranial bleeding being amongst the most common clinical manifestations. ADR risk increases with age-related changes in pharmacokinetics and pharmacodynamics, increasing burden of comorbidity, polypharmacy, inappropriate prescribing and suboptimal monitoring of drugs. ADRs are a preventable cause of harm to patients and an unnecessary waste of healthcare resources. Several ADR risk tools exist but none has sufficient predictive value for clinical practice. Good clinical practice for detecting and predicting ADRs in vulnerable patients includes detailed documentation and regular review of prescribed and over-the-counter medications through standardized medication reconciliation. New medications should be prescribed cautiously with clear therapeutic goals and recognition of the impact a drug can have on multiple organ systems. Prescribers should regularly review medication efficacy and be vigilant for ADRs and their contributory risk factors. Deprescribing should occur at an individual level when drugs are no longer efficacious or beneficial or when safer alternatives exist. Inappropriate prescribing and unnecessary polypharmacy should be minimized. Comprehensive geriatric assessment and the use of explicit prescribing criteria can be useful in this regard.

    Adverse drug reactions (ADRs) are a major source of preventable morbidity and mortality, especially among the elderly, who use more drugs and are more sensitive to them. The insurance industry has recently addressed this problem through the implementation of drug interaction alerts to pharmacists in conjunction with immediate online claims adjudication for almost 60% of prescriptions (expected to reach 90% within 5 years). These alerts are based on stored patient drug profiles maintained by pharmacy benefit managers (PBMs) which are updated whenever prescriptions are filled. While these alerts are very helpful, the pharmacist does not prescribe, resulting in time-consuming and costly delays to contact the physician and remedy potential interactions. We have developed and demonstrated the feasibility of the PINPOINT (Pharmaceutical Information Network for prevention of interactions) system for making the drug profile and interaction information easily available to the physician before the prescription is written. We plan to test the cost-effectiveness of the system in a prospective controlled clinical trial.

    1995-01-01

    Our knowledge relating to adverse drug reactions (ADRs) of phytomedicines is highly fragmentary. The aim of this study was to define the prevalence of ADRs following medication with herbal or synthetic expectorants. In a multicentre, comparative post-marketing surveillance study of more than 3000 patients with acute bronchitis, about half were treated with a herbal remedy (SinupretR) and the other half with various other expectorants. In ascending order of incidence, ADRs were noted during mono-medication of SinupretR (0.8%), Ambroxol (1.0%) and acetylcysteine (4.3%). When concomitant drugs were used, this rank order was unchanged but incidence rates were markedly increased (3.4, 6.5 and 8.2%, respectively). The most frequent ADRs were gastrointestinal symptoms. It is concluded that expectorants are associated with ADRs in roughly 1-5% of cases undergoing single drug treatment and in 3-10% when more than one medication is being used. Amongst the expectorants used in this study, the herbal preparation SinupretR is associated with the lowest incidence of ADRs.

    The severe adverse reaction to vitamin K1 injection is always remarkable and is thought to result from anaphylaxis. Paradoxically, however, some patients administered vitamin K1 injection for the first time have adverse reactions. Using beagle dogs, the present study tested the hypothesis that the response to vitamin K1 is an anaphylactoid reaction. The results showed that serious anaphylaxis-like symptoms appeared in beagle dogs after the administration of vitamin K1 injection for the first time. The plasma histamine concentration increased, and blood pressure decreased sharply. After sensitization, dogs were challenged with vitamin K1 injection and displayed the same degree of symptoms as prior to sensitization. However, when the vitamin K1 injection-sensitized dogs were challenged with a vitamin K1-fat emulsion without solubilizers such asTween-80, the abnormal reactions did not occur. Furthermore, there was no significant change in the plasma immunoglobulin E concentration after vitamin K1 challenge. Following treatment with vitamin K1 injection, the release of histamine and β-hexosaminidase by rat basophilic leukemia-2H3 cells as well as the rate of apoptosis increased. The Tween-80 group displayed results similar to those observed following vitamin K1 injection in vivo. However, the dogs in the vitamin K1-fat emulsion group did not display any abnormal behavior or significant change in plasma histamine. Additionally, degranulation and apoptosis did not occur in rat basophilic leukemia-2H3 cells. Our results indicate that the adverse reaction induced by vitamin K1 injection is an anaphylactoid reaction, not anaphylaxis. Vitamin K1 injection induces the release of inflammatory factors via a non-IgE-mediated immune pathway, for which the trigger may be the solubilizer. PMID:24594861

    Aim: To report the authors' experience with the administration of four gadolinium-based contrast agents (GBCA; gadopentetate dimeglumine, gadofosveset trisodium, gadoxetate disodium and gadobenate dimeglumine) in a large study population at a single, large academic medical centre. Materials and methods: The institutional review board approved this retrospective study in which data in the electronic incident reporting system were searched. A total of 194, 400 intravenous administrations of linear ionic GBCAs were assessed for the incidence of adverse reactions and risk factors from 1 January 2007 to 14 January 2014. The severity of reactions (mild, moderate, and severe), patient type (outpatients, inpatients, and emergency), examination type, and treatment options were also investigated. Results: In total, 204/194400 (0.1%) patients (mean age 45.7 ± 14.9) showed adverse reactions, consisting of 6/746 (0.80%), 10/3200 (0.31%), 14/6236 (0.22%) and 174/184218 (0.09%), for gadofosveset trisodium, gadoxetate disodium, gadobenate dimeglumine, and gadopentetate dimeglumine, respectively. An overall significant difference was found between different GBCAs regarding the total number of reactions (p < 0.0001). When comparing the GBCAs together, significant differences were found between gadofosveset trisodium versus gadopentetate dimeglumine (p < 0.0001), gadofosveset trisodium versus gadobenate dimeglumine (p = 0.0051), gadoxetate disodium versus gadopentetate dimeglumine (p < 0.0001) and gadopentetate dimeglumine versus gadobenate dimeglumine (p = 0.0013). Rate of reaction was higher in females (F: 146/113187, 0.13%/M: 58/81213, 0.07%; p < 0.0001). Rate of reactions was higher in outpatient (180/158885, 0.11%), emergency (10/10413, 0.10%), and inpatients (14/25102, 0.05%), respectively (p < 0.0001). Most of the patients had mild symptoms 171/204 (83.8%). Abdomen–pelvis, liver, and thoracic examinations had highest rates of reactions (0.17 versus 0

    2013-06-01

    Full Text Available Yousef W Nielsen, Henrik S Thomsen Department of Radiology, Copenhagen University Hospital Herlev, Copenhagen, Denmark Abstract: Acute adverse reactions to iodine-based contrast media occur within 60 minutes of administration. The reactions range from mild (flushing, arm pain, nausea/vomiting, headache to moderate (bronchospasm, hypotension, and severe (cardiovascular collapse, laryngeal edema, convulsions, arrhythmias. Most acute adverse reactions occur in an unpredictable manner. Use of the older group of ionic iodine-based contrast agents increases the risk of acute adverse reactions. Other risk factors include previous reactions to contrast media, asthma, and allergic conditions. The exact pathophysiology of the acute adverse reactions is unknown, but some of the reactions are pseudoallergic mimicking type 1 allergic reactions. As antibodies against contrast media have not been consistently demonstrated, the reactions are, in most cases, not truly allergic in nature. Most of the severe and fatal adverse reactions occur within the first 20 minutes after injection. Thus, it is important that patients are observed in the radiology department during this period. The radiologist should be near the room where contrast media is administered, and be ready to treat any acute nonrenal adverse reaction. Appropriate drugs and resuscitation equipment should be in/near the room where the contrast media is administered. The important first-line management of acute adverse reactions includes the establishment of an adequate airway, oxygen supplementation by mask, intravenous fluid administration, and measurement of blood pressure and heart rate. When severe anaphylactoid reactions occur, adrenaline should be given intramuscularly. Only one concentration of adrenaline (1:1000–1 mg/mL should be available in the radiology department to avoid dosing errors in stressful acute settings. Resuscitation team specialists should be the only ones giving intravenous

    Lumpy skin disease (LSD) is an emerging disease in the Middle East region and has been recently reported in Jordan. The aim of this study was to investigate the adverse reactions that were reported after vaccine administration. Geographical areas enrolled in the study were free of the disease and away from the outbreak governorate. Sixty-three dairy cattle farms, with a total of 19,539 animals, were included in the study. Of those, 56 farms reported adverse clinical signs after vaccine administration. The duration between vaccine administration and appearance of adverse clinical signs ranged from 1 to 20 days (Mean = 10.3, SD ± 3.9). Clinical signs were similar to those observed with natural cases of lumpy skin disease. These were mainly fever, decreased feed intake, decreased milk production and variable sized cutaneous nodules (a few millimetres to around 2 cm in diameter) that could be seen anywhere on the body (head, neck, trunk, perineum), udder, and/or teats. Nodules were raised and firm initially and then formed dry scabs that could be peeled off the skin. The characteristic deep 'sit fast' appearance was rarely seen and most lesions were superficial. Some cattle had swollen lymph nodes, while a few pregnant animals aborted. The percentage of affected cattle ranged from 0.3 to 25% (Mean = 8, SD ± 5.1). Fever, decreased feed intake, and decreased milk production were seen in 83.9, 85.7, and 94.6% in cattle on the affected farms, respectively. All affected cattle displayed skin nodules over their entire bodies, while 33.9 and 7.1% of the affected farms reported nodular lesions present on the udders and teats, respectively. No mortalities were reported due to vaccine adverse reactions. Duration (course) of clinical signs ranged from 3 to 20 days (Mean = 13.7, SD ± 4.1). Two types of LSD vaccines were used by the farmers in this study. The first one was a sheep pox virus (SPPV) vaccine derived from the RM65 isolate [Jovivac, manufactured by Jordan

    Transplantation of hematopoietic stem cells (HSCs) has been successfully developed as a part of treatment protocols for a large number of clinical indications, and cryopreservation of both autologous and allogeneic sources of HSC grafts is increasingly being used to facilitate logistical challenges in coordinating the collection, processing, preparation, quality control testing and release of the final HSC product with delivery to the patient. Direct infusion of cryopreserved cell products into patients has been associated with the development of adverse reactions, ranging from relatively mild symptoms to much more serious, life-threatening complications, including allergic/gastrointestinal/cardiovascular/neurological complications, renal/hepatic dysfunctions, and so on. In many cases, the cryoprotective agent (CPA) used-which is typically dimethyl sulfoxide (DMSO)-is believed to be the main causal agent of these adverse reactions and thus many studies recommend depletion of DMSO before cell infusion. In this paper, we will briefly review the history of HSC cryopreservation, the side effects reported after transplantation, along with advances in strategies for reducing the adverse reactions, including methods and devices for removal of DMSO. Strategies to minimize adverse effects include medication before and after transplantation, optimizing the infusion procedure, reducing the DMSO concentration or using alternative CPAs for cryopreservation and removing DMSO before infusion. For DMSO removal, besides the traditional and widely applied method of centrifugation, new approaches have been explored in the past decade, such as filtration by spinning membrane, stepwise dilution-centrifugation using rotating syringe, diffusion-based DMSO extraction in microfluidic channels, dialysis and dilution-filtration through hollow-fiber dialyzers and some instruments (CytoMate, Sepax S-100, Cobe 2991, microfluidic channels, dilution-filtration system, etc.) as well.

    Dear Editor, Inhibition of the epidermal growth factor receptor (EGFR) is a new strategy in treatment of a variety of solid tumors, such as colorectal carcinoma, non-small cell lung cancer, squamous cell carcinoma of the head and neck, and pancreatic cancer (1). Cetuximab is a chimeric human-murine monoclonal antibody against EGFR. Cutaneous side effects are the most common adverse reactions occurring during epidermal growth factor receptor inhibitors (EGFRI) therapy. Papulopustular rash (acne like rash) develop with 80-86% patients receiving cetuximab, while xerosis, eczema, fissures, teleangiectasiae, hyperpigmentations, and nail and hair changes occur less frequently (2). The mechanism underlying these skin changes has not been established and understood. It seems EGFRI alter cell growth and differentiation, leading to impaired stratum corneum and cell apoptosis (3-5). An abdominoperineal resection of the rectal adenocarcinoma (Dukes C) was performed on a 43-year-old female patient. Following surgery, adjuvant chemo-radiotherapy was applied. After two years, the patient suffered a metastatic relapse. Abdominal lymphadenopathy was detected on multi-slice computer tomography (MSCT) images, with an increased value of the carcinoembryonic antigen (CEA) tumor marker (maximal value 57 ng/mL). Hematological and biochemical tests were within normal limits, so first-line chemotherapy with oxaliplatin and a 5-fluorouracil (FOLFOX4) protocol was introduced. A wild type of the KRAS gene was confirmed in tumor tissue (diagnostic prerequisite for the introduction of EGFRI) and cetuximab (250 mg per m2 of body surface) was added to the treatment protocol. The patient responded well to the treatment with confirmed partial regression of the tumor formations. Three months after the patient started using cetuximab, an anti-EGFR monoclonal antibody, the patient presented with a papulopustular eruption in the seborrhoeic areas (Figure 1) and eczematoid reactions on the extremities

    Nalmefene (Selincro®) is a selective opioid receptor antagonist, licensed in April 2014 in Switzerland for the reduction of alcohol consumption in adults with a high drinking risk level. 200 reports of adverse drug reactions of nalmefene have been documented worldwide in the WHO global pharmacovigilance database between 7th March 1997 to 1st March 2015. In 21 cases (10,5%) nalmefene and an opioid were administered concomitantly, causing withdrawal symptoms. Until now, the regional pharmacovigilance center in Zurich received four cases of nalmefene combined with opioids. This combination should be avoided.

    1991-01-01

    During 1988, the Gruppo Italiano Studi Epidemiologici in Dermatologia (GISED) coordinated a pilot study aimed at evaluating the feasibility of a system for spontaneous monitoring of adverse drug reactions in dermatological practice in Italy. Approximately 400 dermatologists were asked to collaborate, and 141 agreed to the study. Procedures similar to those well established in other surveillance programs (including the use of standard forms and standardized assessment procedure) were adopted. In a 2-month period 775 reports were collected, of which 711 were maintained after careful evaluation. The general profile of the adverse reactions reported was in accordance with the experience derived by other spontaneous surveillance programs. The main purpose of spontaneous reporting systems is the identification of new reactions, and a model analysis was proposed, in our study, with reference to skin reactions to bamifylline. The demonstration of the feasibility of a drug-monitoring program in Italy, where little tradition exists in the area, is the most important result of our study.

  4. The mechanisms of delayed onset type adverse reactions to oseltamivir.

    Oseltamivir is recommended for the treatment and prophylaxis of influenza in persons at higher risk for influenza complications such as individuals with diabetes, neuropsychiatric illnesses, and respiratory, cardiac, renal, hepatic or haematological diseases. However, a recent Cochrane review reported that reduction of antibody production, renal disorders, hyperglycaemia, psychiatric disorders, and QT prolongation may be related to oseltamivir use. The underlying mechanisms are reviewed. There is decisive evidence that administration of a clinically compatible dose of oseltamivir in mice challenged by a respiratory syncytial virus (RSV) that lacks a neuraminidase gene showed symptom-relieving effects and inhibition of viral clearance. These effects were accompanied by decreased level of T cell surface sialoglycosphingolipid (ganglioside) GM1 that is regulated by the endogenous neuraminidase in response to viral challenge. Clinical and non-clinical evidence supports the view that the usual dose of oseltamivir suppresses pro-inflammatory cytokines such as interferon-gamma, interleukin-6, and tumour necrosis factor-alpha almost completely with partial suppression of viral shedding in human influenza virus infection experiment. Animal toxicity tests support the clinical evidence with regard to renal and cardiac disorders (bradycardia and QT prolongation) and do not disprove the metabolic effect. Reduction of antibody production and cytokine induction and renal, metabolic, cardiac, and prolonged psychiatric disorders after oseltamivir use may be related to inhibition of the host's endogenous neuraminidase. While the usual clinical dose of zanamivir may not have this effect, a higher dose or prolonged administration of zanamivir and other neuraminidase inhibitors may induce similar delayed reactions, including reduction of the antibody and/or cytokine production.

    Herbal products are readily available over the counter in health food stores and are often perceived to be without risk. The current Canadian adverse event reporting system suffers from severe underreporting, resulting in a scarcity of safety data on herbal products. Twelve health food store personnel in the Greater Toronto Area were interviewed about their responses to herbal product-related adverse reactions. They generally fostered customer loyalty by offering generous return policies, which included collecting contact information to be sent to the manufacturers with the returned product. Thus, despite the public's lack of knowledge about the formal reporting system, adverse reaction information was directed to manufacturers whenever it resulted in a product return. The relationship between health food stores, industry and Health Canada provides a new opportunity to facilitate adverse event reporting. Additional information could be collected during the return process, and educational initiatives could be implemented to augment current post-market surveillance procedures for herbal products.

    Full Text Available Hyperbaric oxygen therapy (HBOT is a safe treatment, provided fulfilling certain rules of patient qualifications to treatment, as well as supervision over the course of therapy by qualified medical staff. Side effects reported in the literature are rare, and are usually mild and transient. Professional medical staff allows minimising the adverse events occurrence. The scale of complications is unknown, especially in Polish hyperbaric center. Careful analysis could be used to develop prevention procedures for patients of hyperbaric oxygen therapy. Hyperbaric Oxygen Centre and Wound Treatment in Bydgoszcz during 28 months performed hyperbaric oxygen therapy (HBOT in case of 423 patients. During this period, adverse events occurred occasionally. 17 cases have been reported. Authors described study case 77 year-old patient who was admitted due to non-healing wound-left lower abdomen (state after radiotherapy. During the fourth session, on decompression phase patient have had a generalized seizure (tonic-clonic. The decompression was stopped, the oxygen supply was disconnected but only after the drug administration seizures terminated. The most likely causative agent of the adverse reactions of the patient treated with HBOT was the oxygen toxic effect on the brain tissue. However, analyzing the circumstances of the seizure termination: phase of decompression at the pressure 2ATA and lack of oxygen disconnection response, it cannot be excluded other causes of this complication.

    Thalidomide and lenalidomide are structural analogs and immunomodulatory drugs. Lenalidomide appears to have a different safety profile than thalidomide and could be less toxic, and as far as we know, we did not found any study comparing their safety profile. The objective of our study was to review and compare serious adverse drug reactions (SADRs) of thalidomide and lenalidomide spontaneously reported to the French Pharmacovigilance database. We extracted all medically confirmed spontaneous reports of SADR for lenalidomide-based regimens and thalidomide-based regimens from the French Pharmacovigilance database. A "serious" adverse drug reaction (ADR) was defined as an ADR that is fatal or life threatening, which causes hospitalization or prolongation of hospitalization, or permanent or significant disability. The study period was between marketing of 2 drugs and January 15, 2012. A total of 392 SADRs related to thalidomide-based regimens were identified in 244 patients and 377 SADRs related to lenalidomide-based regimens in 220 patients. In spite of their structural analogy, this study highlights interesting differences between lenalidomide and thalidomide's safety profile: nervous system and vascular disorders are more frequent with thalidomide-based regimens while hematologic, skin, infectious disorders and secondary primary cancers are more frequent with lenalidomide-based regimens.

    Iodinated contrast media are widely used in computed tomography and angiography. Adverse reactions such as contrast-medium induced nephropathy (CIN), anaphylactoid reactions and iodine-induced thyrotoxicosis are associated with intravasal administration of contrast agents. Iodinated contrast agents are generally considered to be safe, but in rare cases they can cause severe life threatening situations. In this review we present an overview about the incidence, pathways, and risk factors of adverse reactions. Simple schemes including hydration protocols for prevention of CIN, medication for prophylaxis of iodine-induced thyrotoxicosis with thyreostatics and anaphylactoid reactions with histamine antagonists and corticosteroids are suggested.

    2014-10-01

    Severe skin reactions occur less frequently with eslicarbazepine (ESL) than with the other aromatic anticonvulsants. We report the first case of cutaneous adverse drug reaction (CADR) to ESL and co-sensitization between ESL and betalactams. A 41-year-old white woman developed focal epilepsy due to a meningioma that was removed. As post-operatory complication, she suffered meningitis as well as a maculo-papular erythema caused by the treatment with meropenem. Subsequently, ESL was started and gradually increased until 800 mg/day. Twenty-five days later, the patient developed an Erythema Multiforme Major (EMM). Strong positive immediate reaction was induced by prick test with carbamazepine (CBZ) and ESL at 0.01 and 0.1% within 15 and 30 minutes; however the delayed reading at 48 hours was negative. The patient was not carrier of the HLA alleles A3101 and B1502 associated with CBZ induced EMM. The hypersensitivity pathogenic mechanism of EMM is unclear and a delayed hypersensitivity process is speculated. However, the patch and intradermal tests in our patient did not show a delayed reaction but an immediate cutaneous one. A first allergic episode may elicit a massive nonspecific activation of the immune system, providing an enhanced expression of co-stimulatory molecules that decreases the level of tolerance to other drugs. When prescribing ESL, we suggest ruling out previous CADR, especially to CBZ and oxcarbazepine but also other chemically unrelated drugs such as beta-lactams. PMID:25422574

    2013-01-01

    Purpose Adverse symptom event reporting is vital as part of clinical trials and drug labeling to ensure patient safety and inform risk–benefit decision making. The purpose of this study was to assess the reliability of adverse event reporting of different clinicians for the same patient for the same visit. Methods A retrospective reliability analysis was completed for a sample of 393 cancer patients (42.8% men; age 26–91, M = 62.39) from lung (n = 134), prostate (n = 113), and Ob/Gyn (n = 146) clinics. These patients were each seen by two clinicians who independently rated seven Common Terminology Criteria for Adverse Events (CTCAE) symptoms. Twenty-three percent of patients were enrolled in therapeutic clinical trials. Results The average time between rater evaluations was 68 min. Intraclass correlation coefficients were moderate for constipation (0.50), diarrhea (0.58), dyspnea (0.69), fatigue (0.50), nausea (0.52), neuropathy (0.71), and vomiting (0.46). These values demonstrated stability over follow-up visits. Two-point differences, which would likely affect treatment decisions, were most frequently seen among symptomatic patients for constipation (18%), vomiting (15%), and nausea (8%). Conclusion Agreement between different clinicians when reporting adverse symptom events is moderate at best. Modification of approaches to adverse symptom reporting, such as patient self-reporting, should be considered. PMID:21984468

    Patients with suspected cutaneous adverse drug reactions are often referred to allergy clinics or departments of dermatology for evaluation. These patients are selected compared with patients identified in prospective and cross-sectional studies of hospital populations. This explains the observed...... variation in prevalence of specific reactions and of eliciting drugs. This study investigated the prevalence of cutaneous adverse drug reactions in a university hospital department of dermatology that is specially focused on allergy. An 8-month survey was carried out during the period April-December 2003...

    Quinine is a common cause of drug-induced thrombocytopenia and the most common cause of drug-induced thrombotic microangiopathy. Other quinine-induced systemic disorders have been described. To understand the complete clinical spectrum of adverse reactions to quinine we searched 11 databases for articles that provided sufficient data to allow evaluation of levels of evidence supporting a causal association with quinine. Three reviewers independently determined the levels of evidence, including both immune-mediated and toxic adverse reactions. The principal focus of this review was on acute, immune-mediated reactions. The source of quinine exposure, the involved organ systems, the severity of the adverse reactions, and patient outcomes were documented. One hundred-fourteen articles described 142 patients with definite or probable evidence for a causal association of quinine with acute, immune-mediated reactions. These reactions included chills, fever, hypotension, painful acral cyanosis, disseminated intravascular coagulation, hemolytic anemia, thrombocytopenia, neutropenia, acute kidney injury, rhabdomyolysis, liver toxicity, cardiac ischemia, respiratory failure, hypoglycemia, blindness, and toxic epidermal necrolysis. One hundred-two (72%) reactions were caused by quinine pills; 28 (20%) by quinine-containing beverages; 12 (8%) by five other types of exposures. Excluding 41 patients who had only dermatologic reactions, 92 (91%) of 101 patients had required hospitalization for severe illness; 30 required renal replacement therapy; three died. Quinine, even with only minute exposure from common beverages, can cause severe adverse reactions involving multiple organ systems. In patients with acute, multi-system disorders of unknown origin, an adverse reaction to quinine should be considered.

    Nephrogenic systemic fibrosis is a fibrosing disorder that affects patients with impaired renal function and is associated with the administration of gadolinium-based contrast media used in MRI. Despite being in a group of drugs that were considered safe, report about this potentially serious adverse reaction was a turning point in the administration guidelines of these contrast media. There has been an attempt to establish safety parameters to identify patients with risk factors of renal failure. The close pharmacovigilance and strict observation of current regulations, with special attention being paid to the value of glomerular filtration, have reduced the published cases involving the use of gadolinium-based contrast media. In a meeting between radiologists and nephrologists we reviewed the most relevant aspects currently and recommendations for its prevention.

    Drug-induced liver injury (DILI) is among the most challenging acute or chronic liver conditions to be handled by physicians. Despite its low incidence in the general population, DILI is a frequent cause of acute liver failure. As such, the possibility of DILI should be considered in all patients who present with acute liver damage, independent of any known pre-existing liver disease. DILI can be classified as intrinsic/dose-dependent (e.g., acetaminophen toxicity) or idiosyncratic/dose-independent, with the latter form being relatively uncommon. Amoxicillin-clavulanate is the antimicrobial that is most frequently associated with idiosyncratic DILI. Large, ongoing, prospective studies in western countries have reported other drugs associated with DILI, including nonsteroidal anti-inflammatory drugs, statins, and herbal and dietary supplements. An important safety issue, DILI is one of the most frequently cited reasons for cessation of drug development during or after preclinical studies and for withdrawal of a drug from the market. This review summarizes the epidemiology, risk factors, commonly implicated drugs, clinical features, and diagnosis of DILI, with the aim of aiding physicians in the management of this debated problem. Old and new biomarkers for DILI and pharmacogenetic studies are also described. PMID:26827101

  11. The logic of surveillance guidelines: an analysis of vaccine adverse event reports from an ontological perspective.

    Directory of Open Access Journals (Sweden)

    Mélanie Courtot

    Full Text Available BACKGROUND: When increased rates of adverse events following immunization are detected, regulatory action can be taken by public health agencies. However to be interpreted reports of adverse events must be encoded in a consistent way. Regulatory agencies rely on guidelines to help determine the diagnosis of the adverse events. Manual application of these guidelines is expensive, time consuming, and open to logical errors. Representing these guidelines in a format amenable to automated processing can make this process more efficient. METHODS AND FINDINGS: Using the Brighton anaphylaxis case definition, we show that existing clinical guidelines used as standards in pharmacovigilance can be logically encoded using a formal representation such as the Adverse Event Reporting Ontology we developed. We validated the classification of vaccine adverse event reports using the ontology against existing rule-based systems and a manually curated subset of the Vaccine Adverse Event Reporting System. However, we encountered a number of critical issues in the formulation and application of the clinical guidelines. We report these issues and the steps being taken to address them in current surveillance systems, and in the terminological standards in use. CONCLUSIONS: By standardizing and improving the reporting process, we were able to automate diagnosis confirmation. By allowing medical experts to prioritize reports such a system can accelerate the identification of adverse reactions to vaccines and the response of regulatory agencies. This approach of combining ontology and semantic technologies can be used to improve other areas of vaccine adverse event reports analysis and should inform both the design of clinical guidelines and how they are used in the future. AVAILABILITY: Sufficient material to reproduce our results is available, including documentation, ontology, code and datasets, at http://purl.obolibrary.org/obo/aero.

    2012-05-01

    Increased, often inappropriate, drug exposure, pharmacokinetic and pharmacodynamic changes, reduced homeostatic reserve and frailty increase the risk of adverse drug reactions (ADRs) in the older population, thereby imposing a significant public health burden. Predicting and diagnosing ADRs in old age presents significant challenges for the clinician, even when specific risk scoring systems are available. The picture is further compounded by the potential adverse impact of several drugs on more 'global' health indicators, for example, physical function and independence, and the fragmentation of care (e.g., increased number of treating doctors and care transitions) experienced by older patients during their clinical journey. The current knowledge of drug safety in old age is also curtailed by the lack of efficacy and safety data from pre-marketing studies. Moreover, little consideration is given to individual patients' experiences and reporting of specific ADRs, particularly in the presence of cognitive impairment. Pending additional data on these issues, the close review and monitoring of individual patients' drug prescribing, clinical status and biochemical parameters remain essential to predict and detect ADRs in old age. Recently developed strategies, for example, medication reconciliation and trigger tool methodology, have the potential for ADRs risk mitigation in this population. However, more information is required on their efficacy and applicability in different healthcare settings. PMID:22512705

    Full Text Available Background: Chemotherapy, a multimodal approach to oncological treatment, involves highly complex regimens and hence accounts to high susceptibility toward adverse drug reactions (ADRs. The present study aims to determine the prevalence of adverse events in patients treated with chemotherapy. Materials and Methods: Spontaneous ADR report of patients on antineoplastic drugs received in the past 2 years (January 2011-January 2013 were studied. These reports were analyzed for various carcinomas under treatment, medications used, types of ADRs, organ system involvement, severity, causality assessment, and preventability. Results: Over a period of 2 years, a total 591 cases were received with an incidence of 58.6%. The prevalence of ADRs was more in female patients (73.6% as compared to men. ADRs mostly occurred in the age group of 41-50 years (27.4%. Patients treated for breast carcinoma (39.1% reported the highest incidence of ADRs. Cisplatin (19.6% was found to be the most common offending drug. The most common ADR reported was nausea and vomiting (23%. Gastroenterology (40.1% was the most affected system. About 50.2% of the ADRs required treatment and 12.9% ADRs were considered serious. Causality assessment revealed that 80% of the ADRs were possible. About 86.97% cases were found to be mild, and 51% were not preventable. Conclusion: The success of chemotherapy comes with the word of caution regarding toxicities of antineoplastic drugs. Pharmacovigilance of these drugs needs to be explored, and use of preventative measures needs to be enhanced in order to reduce the incidence and severity of ADRs.

    The aim of this study was to evaluate two commercially available selected-protein-source diets as maintenance diets in cats with dermatological manifestations of adverse food reactions. Twenty cats with a confirmed adverse food reaction were tested in a double-blind manner. An adverse food reaction was diagnosed when, after recovery with a home-cooked elimination diet, the signs relapsed after a challenge with their previous dietary components, and re-disappeared on a second elimination diet period. Hereafter the cats were blind and randomly challenged with two commercial hypoallergenic diets. Relapse of the clinical signs was seen in eight cats (40%) on a lamb and rice diet and in 13 cats (65%) on a chicken and rice diet (P>0.05). Neither one of the commercial diets was as effective in controlling the skin problems as the home-cooked elimination diet. The study confirms that commercial hypoallergenic diets are adequate for maintenance.

    Adverse reaction to metal debris (ARMD) in total hip arthroplasty surgery is a well-known problem. We present the case of a unipolar hemiarthroplasty requiring revision within 18 months of insertion secondary to an adverse reaction to metal debris. This case demonstrates a rare cause for failure of a hemiarthroplasty following a fragility fracture. We feel that ARMD should be considered in all cases where pain and dysfunction in the presence of any hip prosthesis cannot be explained by routine investigations. PMID:27656196

    In the second of a two-part article on adverse drug reactions Agnes Kanneh describes the six 'rights' of the recipient of a drug. These are: that the right person should receive the right drug, in the right dose, at the right time within the right intervals, via the right route, followed by the right (correct) documentation. The author argues that the observance of these 'rights' by children's nurses ensures the best pharmacotherapeutic practice, thus a robust practical safeguard in adverse drug reactions and threats to the good reputation of the nursing profession.

    Full Text Available Nicholas Moore,1 Charles Pollack,2 Paul Butkerait2 1Department of Pharmacology, Université de Bordeaux, Bordeaux, France; 2Pfizer Consumer Healthcare, Madison, NJ, USA Abstract: Nonsteroidal anti-inflammatory drugs (NSAIDs such as ibuprofen have a long history of safe and effective use as both prescription and over-the-counter (OTC analgesics/antipyretics. The mechanism of action of all NSAIDs is through reversible inhibition of cyclooxygenase enzymes. Adverse drug reactions (ADRs including gastrointestinal bleeding as well as cardiovascular and renal effects have been reported with NSAID use. In many cases, ADRs may occur because of drug–drug interactions (DDIs between the NSAID and a concomitant medication. For example, DDIs have been reported when NSAIDs are coadministered with aspirin, alcohol, some antihypertensives, antidepressants, and other commonly used medications. Because of the pharmacologic nature of these interactions, there is a continuum of risk in that the potential for an ADR is dependent on total drug exposure. Therefore, consideration of dose and duration of NSAID use, as well as the type or class of comedication administered, is important when assessing potential risk for ADRs. Safety findings from clinical studies evaluating prescription-strength NSAIDs may not be directly applicable to OTC dosing. Health care providers can be instrumental in educating patients that using OTC NSAIDs at the lowest effective dose for the shortest required duration is vital to balancing efficacy and safety. This review discusses some of the most clinically relevant DDIs reported with NSAIDs based on major sites of ADRs and classes of medication, with a focus on OTC ibuprofen, for which the most data are available.

    Dag Ø. Nordanger

    2014-05-01

    Full Text Available Background: Former studies suggest that prior exposure to adverse experiences such as violence or sexual abuse increases vulnerability to posttraumatic stress reactions in victims of subsequent trauma. However, little is known about how such a history affects responses to terror in the general adolescent population. Objective: To explore the role of prior exposure to adverse experiences as risk factors for posttraumatic stress reactions to the Oslo Terror events. Method: We used data from 10,220 high school students in a large cross-sectional survey of adolescents in Norway that took place seven months after the Oslo Terror events. Prior exposure assessed was: direct exposure to violence, witnessing of violence, and unwanted sexual acts. We explored how these prior adversities interact with well-established risk factors such as proximity to the events, perceived life threat during the terror events, and gender. Results: All types of prior exposure as well as the other risk factors were associated with terror-related posttraumatic stress reactions. The effects of prior adversities were, although small, independent of adolescents’ proximity to the terror events. Among prior adversities, only the effect of direct exposure to violence was moderated by perceived life threat. Exposure to prior adversities increased the risk of posttraumatic stress reactions equally for both genders, but proximity to the terror events and perceived life threat increased the risk more in females. Conclusions: Terror events can have a more destabilizing impact on victims of prior adversities, independent of their level of exposure. The findings may be relevant to mental health workers and others providing post-trauma health care.

    Background Sublingual allergen immunotherapy is an effective treatment against allergic respiratory disease. Many studies have shown the safety of this type of therapy, although the factors that might affect the tolerability of high-dose sublingual immunotherapy have not been well established. The aim of this study was to determine the factors that affect the tolerability of sublingual allergen immunotherapy. Patients and methods A total of 183 subjects aged ≥5 years, diagnosed with allergic rhinitis with/without mild to moderate asthma due to sensitization to grass, olive pollen, or mites, were included in this open, retrospective, multicentric, noninterventional study. Sublingual immunotherapy was administered for at least 3 months. Results The most frequent adverse reaction was oral pruritus (13.7% of the patients). Most of the reactions were local (84.7%) and immediate (93.5%) and occurred during the initiation phase (60.6%). All reactions were mild to moderate in severity. No serious adverse reactions were registered. When comparing factors with potential influence on the occurrence of adverse reactions, the results between the groups of subjects with and without adverse reactions showed no statistically significant differences in sex (P=0.6417), age (P=0.1801), years since the disease was first diagnosed (P=0.3800), treatment composition (P=0.6946), polysensitization (P=0.1730), or clinical diagnosis (P=0.3354). However, it was found that treatment duration had a statistically significant influence (3 months, >3 months: P=0.0442) and the presence of asthma was close to statistical significance (P=0.0847). Conclusion In our study, treatment duration is significantly associated with the occurrence of adverse reactions after the administration of high doses of sublingual allergen immunotherapy.

    2011-01-01

    Full Text Available We report a case of a 34-year-old woman presenting with an erythema multiforme (EM-like eruption. Lesions developed after a 12-day treatment with a slimming drug preparation (food integrator with thermogenic activity and a herbal remedy (pilosella tincture. Serological investigations excluded viral or bacterial infections. Patch testing with galenic preparations of both drugs demonstrated sensitization to the slimming drug preparation. According to literature reports and immune-chemical properties, those components that are likely to have triggered the skin eruption are clorazepate dipotassium and theobromine. Their interaction with other two constituents such as pseudoephedrine hydrochloride and dehydrocholic acid may have caused the adverse reaction by means of a summation effect. There are no reports specifically about EM caused by a slimming drug preparation and no studies have identified thermogenic pills as cause of EM/EM-like eruption. Weight-loss compounds in slimming preparations should be kept in mind as a possible cause of drug-induced EM-like eruption.

This study will also help in understanding the problems faced by blood banks/Transfusion Medicine departments in implementing an effective hemovigilance program. Materials and Methods: All the adverse reactions related to transfusion of whole blood and its components in various clinical specialties were studied for a period of 1 year. Any transfusion-related adverse event was worked up in accordance with guidelines laid down by the Directorate General of Health Services (DGHS and departmental standard operating procedures. Results: During the study period from November 1, 2011 to October 31, 2012, 45812 components were issued [30939 WB/PRBC; 12704 fresh frozen plasma (FFP; 2169 platelets]. Risk estimation per 1000 units of red cells (WB/PRBC transfused was estimated to be: 0.8 for febrile nonhemolytic transfusion reaction (FNHTR, 0.7 for allergic reaction, 0.19 for acute hemolytic transfusion reaction (AcHTR, 0.002 for anaphylactoid reactions, 0.1 for bacterial sepsis, and 0.06 for hypervolemia and hypocalcemia. 0.09 is the risk for delayed transfusion reaction and 0.03 is the risk for transfusion-related acute lung injury (TRALI. Risk estimate per 1,000 units of platelets transfused was estimated to be 1.38 for FNHTR, 1.18 for allergic reaction, and 1 in case of bacterial sepsis. Risk estimation per 1,000 units of FFP was estimated to be 0.15 for FNHTR and 0.2 for allergic reactions. Conclusions: Factors such as clerical checks at various levels, improvement in blood storage conditions outside blood banks, leukodepletion, better inventory management, careful donor screening, bedside monitoring of transfusion, and documentation of adverse events may decrease transfusion-related adverse events. Better coordination between transfusion specialists and various clinical

    Reasons for resident underutilization of adverse event (AE) reporting systems are unclear, particularly given frequent resident exposure to AEs and near misses (NMs). Residents at an academic medical center were surveyed about AEs/NMs, barriers to reporting, patient safety climate, and educational interventions. A total of 350 of 527 eligible residents (66%) completed the survey; 77% of respondents reported involvement in an AE/NM, though only 43% had used the reporting system. Top barriers to reporting were not knowing what or how to report. Surgeons reported more than other residents (surgery, 61%; medical, 38%; hospital-based, 15%; P systems were unlikely to change after reporting (surgery, 49%; medical, 28%; hospital-based. 18%; P system effectiveness, and educational preferences.

    Full Text Available Background: The goal of hemovigilance is to increase the safety and quality of blood transfusion. Identification of the adverse reactions will help in taking appropriate steps to reduce their incidence and make blood transfusion process as safe as possible. Aims : To determine the frequency and type of transfusion reactions (TRs occurring in patients, reported to the blood bank at our institute. Materials and Methods : A retrospective review of all TRs reported to the blood bank at the All India Institute of Medical Sciences, between December 2007 and April 2012 was done. All the TRs were evaluated in the blood bank and classified using standard definitions. Results: During the study period a total of 380,658 bloods and blood components were issued by our blood bank. Out of the total 196 adverse reactions reported under the hemovigilance system, the most common type of reaction observed was allergic 55.1% (n = 108, followed by febrile non-hemolytic transfusion reaction (FNHTR 35.7% (n = 70. Other less frequently observed reactions were Anaphylactoid reactions 5.1% (n = 10, Acute non-immune HTRs 2.6% (n = 5, Circulatory overload 0.5% (n = 1, Transfusion related acute lung injury 0.5% (n = 1, Delayed HTRs 0.5% (n = 1. Not a single case of bacterial contamination was observed. Conclusion: The frequency of TRs in our patients was found to be 0.05% (196 out of 380,658. This can be an underestimation of the true incidence because of under reporting. It should be the responsibility of the blood transfusion consultant to create awareness amongst their clinical counterpart about safe transfusion practices so that proper hemovigilance system can be achieved to provide better patient care.

    Full Text Available Background: Novel atypical antipsychotics are superior to conventional antipsychotics as they significantly reduce both positive and negative symptoms of schizophrenia and have lower risk of extrapyramidal symptoms (EPS. However, these drugs have separate set of adverse drug reactions (ADRs. Therefore, this study was carried out to assess these ADRs, which can have impact on long-term compliance and achieving successful treatment. Materials and Methods: A prospective study of analysis of ADR of atypical antipsychotic drugs was carried out in the psychiatry outpatient department. Patients of psychotic disorder (any age, either sex, who were prescribed atypical antipsychotic drugs, were included. Those who were prescribed conventional antipsychotics or combinations of antipsychotics were excluded from the study. Apart from spontaneously reported ADRs, a questionnaire related to the likely ADR was used and patients′ responses were recorded in the case record form. Results: Totally 93 ADRs were recorded from 84 prescriptions. Majority of the ADRs (82 out of 93 were seen with risperidone and olanzepine, as they were the commonly prescribed drugs. Weight gain, dizziness, sleep disturbance and appetite disturbance accounted for nearly 78% of the total events. With risperidone (at 4-6 mg/day and olanzepine (at 10-15 mg/day, gastrointestinal and sleep disturbance were observed in the initial (within 7 days to 2-3 months after treatment course of treatment, while EPS, fatigue, seizure, increased frequency of micturition and dizziness were observed after long-term (3-9 months use. Conclusion: The present study adds to the existing information on the prevalence of adverse effects of atypical antipsychotic drugs. Role of active surveillance in post-marketing phase is also emphasized.

    Adverse drug reaction (ADR) risk-prediction models for use in older adults have been developed, but it is not clear if they are suitable for use in clinical practice. This systematic review aimed to identify and investigate the quality of validated ADR risk-prediction models for use in older adults. Standard computerized databases, the gray literature, bibliographies, and citations were searched (2012) to identify relevant peer-reviewed studies. Studies that developed and validated an ADR prediction model for use in patients over 65 years old, using a multivariable approach in the design and analysis, were included. Data were extracted and their quality assessed by independent reviewers using a standard approach. Of the 13,423 titles identified, only 549 were associated with adverse outcomes of medicines use. Four met the inclusion criteria. All were conducted in inpatient cohorts in Western Europe. None of the models satisfied the four key stages in the creation of a quality risk prediction model; development and validation were completed, but impact and implementation were not assessed. Model performance was modest; area under the receiver operator curve ranged from 0.623 to 0.73. Study quality was difficult to assess due to poor reporting, but inappropriate methods were apparent. Further work needs to be conducted concerning the existing models to enable the development of a robust ADR risk-prediction model that is externally validated, with practical design and good performance. Only then can implementation and impact be assessed with the aim of generating a model of high enough quality to be considered for use in clinical care to prioritize older people at high risk of suffering an ADR.

    Full Text Available Snakebites can present local or systemic envenomation, while neurotoxicity and respiratory paralysis are the main cause of death. The mainstay of management is anti-snake venom (ASV, which is highly effective, but liable to cause severe adverse reactions including anaphylaxis. The types of adverse reaction to polyvalent anti-snake venom have not been previously studied in Bangladesh. In this prospective observational study carried out between 1999 and 2001, in the Snake Bite Study Clinic of Chittagong Medical College Hospital, 35 neurotoxic-snake-bite patients who had received polyvalent anti-snake venom were included while the ones sensitized to different antitoxins and suffering from atopy were excluded. The common neurotoxic features were ptosis (100%, external ophthalmoplegia (94.2%, dysphagia (77.1%, dysphonia (68.5% and broken neck sign (80%. The percentage of anti-snake venom reaction cases was 88.57%; pyrogenic reaction was 80.64%; and anaphylaxis was 64.51%. The common features of anaphylaxis were urticaria (80%; vomiting and wheezing (40%; and angioedema (10%. The anti-snake venom reaction was treated mainly with adrenaline for anaphylaxis and paracetamol suppository in pyrogenic reactions. The average recovery time was 4.5 hours. Due to the danger of reactions the anti-snake venom should not be withheld from a snakebite victim when indicated and appropriate guidelines should be followed for its administration.

    The adverse event (AE) profiles of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor (statin) agents are of great interest, in particular the most recently approved statin, rosuvastatin. The forwarding of reports of AEs has been shown to be influenced by several reporting biases, including secular trend, the new drug reporting effect, product withdrawals, and publicity. Comparative assessments that use AE reporting rates are difficult to interpret under these circumstances, because such effects can themselves lead to marked increases in AE reporting. Consequently, many comparative reporting rate analyses are best carried out in conjunction with other metrics that put reporting burden into context, such as report proportion. All-AE reporting rates showed a temporal profile that resembled those of other statins when marketing cycle and secular trend were taken into account. A before-and-after cerivastatin withdrawal comparison showed a substantial increase in the reporting of AEs of interest for the statin class overall. Report proportion analyses indicated that the burden of rosuvastatin-associated AEs was similar to that for other statin agents. Analyses of monthly reporting rates showed that the reporting of rosuvastatin-associated rhabdomyolysis and renal failure have increased following AE-specific mass media publicity. Postrosuvastatin AE reporting patterns were comparable to those seen with other statins and did not resemble cerivastatin. PMID:16581327

    In the current study we explored the occurrence of adverse drug reactions (ADRs) to antiretroviral therapy among human immune-deficiency virus (HIV)/AIDS patients. We concluded an observational retrospective study in all patients who were diagnosed with HIV infection and were receiving highly active antiviral therapy from Jan. 2007 to Dec. 2012 at Hospital Pulau Pinang, Malaysia. Patient socio-demographic details along with clinical features and susceptible ADRs were observed during the study period. Out of 743 patients, 571 (76.9%) were men, and 172 (23.1%) were women. Overall 314 (42.2%) patients experienced ADRs. A total of 425 ADRs were reported, with 311 (73.1%) occurring in men and 114 (26.8%) in women, with a significant statistical relationship (P value (P) = 0.02, OR = 1.21). Overall 239 (56.2%) ADRs were recorded among Chinese, 94 (22.1%) in Malay, and 71 (16.7%) in Indian patients, which had a statistically significant association with ADRs (P = 0.05, OR = 1.50). Out of a total 425 among ADRs, lipodystrophy was recorded in 151 (35.5%) followed by skin rashes in 80 (18.8%), anemia in 74 (17.4%), and peripheral neuropathy in 27 (6.3%) patients. These findings suggest a need of intensive monitoring of ADRs in HIV treatment centres across Malaysia.

    Bloating, abdominal discomfort or pain, disturbed bowel habits are very common symptoms, frequently reported by the patients soon after food ingestion. These symptoms may occur in different clinical conditions, such as functional bowel disorders, food adverse reactions, gluten-related syndromes, which frequently are interrelated. Consequently, in clinical practice, it is necessary to perform a correct diagnosis in order to identify, for the single patient, the most appropriate therapeutic strategy, which may include not only specific drugs, but also, and mainly, life style changes (healthy nutritional behavior and constant physical activity). The aim of this review is to provide to the general physician, according to the available evidence, the most appropriate diagnostic work-ups for recognizing the different clinical scenarios (i.e. food allergy and intolerance, functional bowel diseases, gluten-related syndromes), to identify their clinical interrelationships and to suggest the most appropriate management. In fact, as far as food intolerances are concerned, it is well known that the number of patients who believe that their symptoms are related to food intolerance is increasing and consequently they restrict their diet, possibly causing nutritional deficiencies. Furthermore, there is an increasing use of unconventional diagnostic tests for food intolerance which lack accurate scientific evidence; the application of their results may induce misdiagnosis and unhealthy therapeutic choices. Consequently the recognition of food intolerance has to be performed on the basis of reliable tests within an agreed diagnostic workup.

    Adverse drug reactions (ADRs) represent a major burden on society, resulting in significant morbidity, mortality, and health care costs. Older patients living in the community are particularly susceptible to ADRs, and are at an increased risk of ADR-related hospitalization. This review summarizes the available evidence on ADR-related hospital admission in older patients living in the community, with a particular focus on risk factors for ADRs leading to hospital admission and the need for a prediction tool for risk of ADR-related hospitalization in these individuals. The reported proportion of hospital admissions due to ADRs has ranged from 6% to 12% of all admissions in older patients. The main risk factors or predictors for ADR-related admissions were advanced age, polypharmacy, comorbidity, and potentially inappropriate medications. There is a clear need to design intervention strategies to prevent ADR-related hospitalization in older patients. To ensure the cost-effectiveness of such strategies, it would be necessary to target them to those older individuals who are at highest risk of ADR-related hospitalization. Currently, there are no validated tools to assess the risk of ADRs in primary care. There is a clear need to investigate the utility of tools to identify high-risk patients to target appropriate interventions toward prevention of ADR-related hospital admissions. PMID:27194906

    Disease-modifying antirheumatic drugs (DMARDs) and biological agents are critical in preventing the severe complications of rheumatoid arthritis (RA). However, the outcome of treatment with these drugs in RA patients is quite variable and unpredictable. Drug-metabolizing enzymes (dihydrofolate reductase, cytochrome P450 enzymes, N-acetyltransferases, etc.), drug transporters (ATP-binding cassette transporters), and drug targets (tumor necrosis factor-α receptors) are coded for by variant alleles. These gene polymorphisms may influence the pharmacokinetics, pharmacodynamics, and side effects of medicines. The cause for differences in efficacy and adverse drug reactions may be genetic variation in drug metabolism among individuals. Polymorphisms in drug transporter genes may change the distribution and excretion of medicines, and the sensitivity of the targets to drugs is strongly influenced by genetic variations. In this article, we review the genetic polymorphisms that affect the efficacy of DMARDs or the occurrence of adverse drug reactions associated with DMARDs in RA.

    With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

    Heparin is a natural agent with antithrombotic action, commercially available for therapeutic use as unfractionated heparin and low molecular weight heparin. Heparin-induced thrombocytopenia (HIT) is a serious adverse reaction to heparin that promotes antibody-mediated platelet activation. HIT is defined as a relative reduction in platelet count of 50% (even when the platelet count at its lowest level is above>150 x 10(9)/L) occurring within five to 14 days after initiation of the therapy. Thrombocytopenia is the main feature that directs the clinical suspicion of the reaction and the increased risk of thromboembolic complications is the most important and paradoxical consequence. The diagnosis is a delicate issue, and requires a combination of clinical probability and laboratory tests for the detection of platelet activation induced by HIT antibodies. The absolute risk of HIT has been estimated between 1% and 5% under treatment with unfractionated heparin, and less than 1% with low molecular weight heparin. However, high-quality evidence about the risk of HIT from randomized clinical trials is scarce. In addition, information on the frequency of HIT in developing countries is not widely available. This review aims to provide a better understanding of the key features of this reaction and updated information on its frequency to health professionals and other interested parties. Knowledge, familiarity, and access to therapeutic options for the treatment of this adverse reaction are mandatory to minimize the associated risks, improving patient safety.

    Intravenous N-acetylcysteine is usually regarded as a safe antidote. However, during the infusion of the loading dose, different types of adverse drug reactions (ADR) may occur. The objective of this study was to investigate the relation between the incidence of different types of ADR and serum acetaminophen concentration in patients presenting to the hospital with acetaminophen overdose. This is a retrospective study of patients admitted to the hospital for acute acetaminophen overdose over a period of 5 years (1 January 2004 to 31 December 2008). Parametric and non-parametric tests were used to test differences between groups depending on the normality of the data. SPSS 15 was used for data analysis. Of 305 patients with acetaminophen overdose, 146 (47.9%) were treated with intravenous N-acetylcysteine and 139 (45.6%) were included in this study. Different types of ADR were observed in 94 (67.6%) patients. Low serum acetaminophen concentrations were significantly associated with cutaneous anaphylactoid reactions but not other types of ADR. Low serum acetaminophen concentration was significantly associated with flushing (p acetaminophen concentrations between patients with and without the following ADR: gastrointestinal reactions (p = 0.77), respiratory reactions (p = 0.96), central nervous reactions (p = 0.82) and cardiovascular reactions (p = 0.37). In conclusion, low serum acetaminophen concentrations were associated with higher cutaneous anaphylactoid reactions. Such high serum acetaminophen concentrations may be protective against N-acetylcysteine-induced cutaneous ADR. PMID:20374238

    Administration of antivenoms to treat snakebite envenomings has the potential risk of inducing early adverse reactions. The mechanisms involved in these reactions are unclear. In this study, polyspecific antivenom consisting of whole IgG purified from equine plasma by caprylic acid precipitation was administered intravenously to non-envenomed horses (n = 47) and cows (n = 20) at a dose of 0.4 mL/kg. It has been reported that, in humans, this formulation (administered at a dose of 0.4 mL/kg) induces mild noticeable early adverse reactions, such as fever, vomiting, diarrhea, urticaria, generalized rash, tachypnea or tachycardia, in about 15-20% of the patients. Unexpectedly, none of the animals receiving antivenom in our study showed any evidence of early adverse reaction. Moreover, no late adverse reactions, i.e. serum sickness, were observed during 40 days after antivenom administration. Unlike studies performed in envenomed humans, our present results were obtained in a group of non-envenomed individuals. It is concluded that, in addition to the physicochemical characteristics of the formulation, other unknown factors must determine the occurrence of adverse reactions in snakebite envenomed humans treated with equine-derived antivenoms.

    2014-03-01

    Full Text Available The use of metal-on-metal (MoM total hip implants has decreased recently due to reports of high failure rates and adverse local tissue reaction (ALTR. It has been hypothesized that wear metal debris released from CoCr bearing surfaces may provoke delayed hypersensitivity reactions. The goal of this study is to evaluate the microscopic bearing surface characteristics of implants revised due to evidence of ALTR. The bearing surface of each head and cup was analyzed using multiple microscopy techniques for characterization of the surface features. The presence of severe mechanical scratching was a common characteristic found in all of the implants evaluated. Mechanical factors seemed to be the prevalent failure mode related to the appearance of ALTR with this particular set of retrieved implants.

    Full Text Available Purpose: Adverse drug reactions (ADRs are adverse consequences of drug therapy. ADRs are representing a major concern of health systems in terms of early recognition, proper management and prevention. Under reporting of Adverse Drug Reactions (ADRs is a common problem in Pharmacovigilance programs. Poor perceptions of doctors about ADRs and risk management have contributed to high rate of ADR under-reporting in India. Underreporting has also been attributed to lack of time to doctor, misconceptions about spontaneous reporting and lack of information on how to report, where to report and a lack of availability of report forms, and also physicians' attitudes to ADRs. The objective of our study was to evaluate the knowledge, attitude and practices (KAP of health care professional towards Pharmacovigilance and adverse drug reactions in a tertiary care hospital, Bhavnagar, Gujarat, India. Methods: A cross-sectional questionnaires based study was carried out in Post graduate students and faculties of tertiary care hospital attached with Govt. Medical College, Bhavnagar, Gujarat. Post graduate students and faculties of different clinical subjects working in the tertiary care teaching hospital, Bhavnagar, Gujarat (India were enrolled and present throughout in study. 22 questionnaires about knowledge, attitude and practices towards ADRs and Pharmacovigilance were developed and peer viewed of all questionnaires by expert faculties from Pharmacology department.

    2015-02-01

    Full Text Available Adverse drug reaction (ADR is widely concerned for public health issue. ADRs are one of most common causes to withdraw some drugs from market. Prescription event monitoring (PEM is an important approach to detect the adverse drug reactions. The main problem to deal with this method is how to automatically extract the medical events or side effects from high-throughput medical events, which are collected from day to day clinical practice. In this study we propose a novel concept of feature matrix to detect the ADRs. Feature matrix, which is extracted from big medical data from The Health Improvement Network (THIN database, is created to characterize the medical events for the patients who take drugs. Feature matrix builds the foundation for the irregular and big medical data. Then feature selection methods are performed on feature matrix to detect the significant features. Finally the ADRs can be located based on the significant features. The experiments are carried out on three drugs: Atorvastatin, Alendronate, and Metoclopramide. Major side effects for each drug are detected and better performance is achieved compared to other computerized methods. The detected ADRs are based on computerized methods, further investigation is needed.

    Iodinated radiocontrast media (IRCM) is widely used in current clinical practice. Although IRCM is generally safe, serious adverse drug reactions (ADRs) may still occur. IRCM-induced ADRs may be subdivided into chemotoxic and hypersensitivity reactions. Several factors have been shown to be associated with an increased risk of ADRs, including previous contrast media reactions, history of asthma and allergic disease, etc. Contrast media with lower osmolality is generally recommended for at-risk patients to prevent ADRs. Current premedication prophylaxis in at-risk patients may reduce the risk of ADRs. However, there is still a lack of consensus on the prophylactic role of premedication. Contrast-induced nephropathy (CIN) is another component of IRCM-related ADRs. Hydration remains the mainstay of CIN prophylaxis in at-risk patients. Despite several preventive measures, ADRs may still occur. Treatment strategies for potential contrast reactions are also summarised in this article. This article summarises the pathophysiology, epidemiology and risk factors of ADRs with emphasis on prevention and treatment strategies. This will allow readers to understand the rationale behind appropriate patient preparation for diagnostic imaging involving IRCM. PMID:27292007

    This study describes the adverse drug reactions (ADRs) and their incidence in patients with rheumatoid arthritis who were treated in the Colombian health system. A retrospective cohort study was conducted using information from all patients who were diagnosed with rheumatoid arthritis and attended specialized health care centers in the cities of Bogotá, Cali, Manizales, Medellin, and Pereira between 1 December 2009 and 30 August 2013. The ADRs were obtained from medical records and the pharmacovigilance system registry and sorted by frequency and affected tissue according to World Health Organization Adverse Reaction Terminology (WHO-ART). A total of 949 reports of ADRs were obtained from 419 patients (32.8 ADRs per 100 patient-years); these patients were from a cohort of 1,364 patients being treated for rheumatoid arthritis and followed up for an average of 23.8 months (± 12.9). The cohort was mostly female (366, 87.4%) and had a mean age of 52.7 years (± 13.1). The highest numbers of ADRs were reported following the use of tocilizumab, rituximab, and infliximab (28.8, 23.1, and 13.3 reports per 100 patient-years respectively). The most frequently reported ADRs were elevated transaminase levels and dyspepsia. Overall, 87.7% of ADRs were classified as type A, 36.6% as mild, 40.7% as moderate, and 22.7% as severe. As a result, 73.2% of patients who experienced an ADR stopped taking their drugs. The occurrence of ADRs in patients treated for rheumatoid arthritis is common, especially in those associated with the use of biotechnologically produced anti-rheumatic drugs. This outcome should be studied in future research and monitoring is needed to reduce the risks in these patients.

Aim: The study was conducted to evaluate the incidence of ADRs due to angiotensin-converting enzyme Inhibitors in cardiology department. Materials and Methods: A cross-sectional observational study was carried out for a period of 6 months. The data were assessed for the pattern of the ADRs with respect to patient demographics, nature of the reaction, outcome of the reactions, causality, severity, and preventability. Results: Among 692 patients, 51 (7.36% had developed 60 ADRs, and majority of cases (56.66% were in the age group of >61 years and most of them were developed in female (80%. The common ADRs observed were cough, hypotension, hyperkalemia, and acute renal failure. In 21.66% cases the dose of the suspected drug was altered and in 78.33% cases the drug was withdrawn. Considering the outcome, 93.33% of cases recovered from ADRs, whereas in 6.66% cases were continuing. Causality assessment showed that majority of ADRs was probable and were found to be moderately severe. Conclusion: Our study concludes geriatrics and female patients have higher incidence of ADRs. So early identification and management of ADRs are essential for this population.

    Evaluation and validation have become a crucial problem for the development of semantic resources. We developed Ci4SeR, a Graphical User Interface to optimize the curation work (not taking into account structural aspects), suitable for any type of resource with lightweight description logic. We tested it on OntoADR, an ontology of adverse drug reactions. A single curator has reviewed 326 terms (1020 axioms) in an estimated time of 120 hours (2.71 concepts and 8.5 axioms reviewed per hour) and added 1874 new axioms (15.6 axioms per hour). Compared with previous manual endeavours, the interface allows increasing the speed-rate of reviewed concepts by 68% and axiom addition by 486%. A wider use of Ci4SeR would help semantic resources curation and improve completeness of knowledge modelling.

    Full Text Available Adverse drug reactions (ADRs are a major clinical problem. In addition to their clinical impact on human health, there is an enormous cost associated with ADRs in health care and pharmaceutical industry. Increasing studies revealed that genetic variants can determine the susceptibility of individuals to ADRs. The development of modern genomic technologies has led to a tremendous advancement of improving the drug safety and efficacy and minimizing the ADRs. This review will discuss the pharmacogenomic techniques used to unveil the determinants of ADRs and summarize the current progresses concerning the identification of biomarkers for ADRs, with a focus on genetic variants for genes encoding drug-metabolizing enzymes, drug-transporter proteins, and human leukocyte antigen (HLA. The knowledge gained from these cutting-edge findings will form the basis for better prediction and management for ADRs, ultimately making the medicine personalized.

    Full Text Available Being key health care professional, physicians, pharmacist and nurses have immense responsibility in reporting adverse drug reaction (ADR. Therefore, the study objective was to evaluate the knowledge, attitude and practices (KAP toward pharmacovigilance and ADRs of postgraduate students of our institute. A cross-sectional questionnaires based study was carried out in postgraduate students of the clinical department at tertiary care hospital attached with Govt. Medical College, Vadodara, Gujarat (India. A total of 22 questionnaires about KAP toward ADRs and pharmacovigilance were developed and peer viewed of all questionnaires by expert faculties from our institute. We were contacted directly to postgraduate students of respective clinical department; questionnaires were distributed and taken back after 30 min. The filled KAP questionnaires were analyzed in question wise and their percentage value was calculated by using Microsoft Excel spreadsheet. Postgraduate residents (n = 101 from different clinical departments were enrolled in the study. Average 34.83% correct and 64.08% incorrect knowledge about ADRs and pharmacovigilance and an average 90.76% students were agreed to reporting ADRs is necessary, mandatory and increased patient′s safety. Only 7.92% of postgraduate doctors were reported ADR at institute or ADR reporting center. We concluded that postgraduate students have a better attitude toward reporting ADRs, but have lack of knowledge and poor practices of ADRs. The majority of postgraduate students were felt ADR reporting and monitoring is very important, but few had ever reported ADRs because of lack of sensitization and knowledge of pharmacovigilance and ADR.

    Full Text Available Purpose: Studies regarding pattern of adverse drug reactions (ADRs in cancer chemotherapy patients are scarce in India. This study was conducted to evaluate the pattern of occurrence of ADRs due to cancer chemotherapy in hospitalized patients and to assess the causality, severity, predictability, and preventability of these reactions. Materials and Methods: This was a retrospective, descriptive study and the occurrence and nature of ADR, suspected drug, duration of hospital stay and outcome were noted from case records. These ADRs were assessed for causality using both World Health Organization (WHO causality assessment scale and Naranjo′s algorithm. The severity and preventability of the reported reactions were assessed using modified Hartwig and Siegel scale and modified Schumock and Thornton scale respectively. Results: Five hundred ADRs were recorded from 195 patients. Most common ADRs were infections (22.4%, nausea/vomiting (21.6% and febrile neutropenia (13%. Platinum compounds, nitrogen mustards, taxanes, antibiotics and 5-fluorouracil were the most common drugs causing ADRs. WHO causality assessment scale showed 65% of the reactions to be "probable" and 35% to be "possible," while Naranjo′s algorithm indicated that 65.6% of ADRs were "probable" and 34.4% were "possible". Modified Hartwig and Siegel scale showed most reactions (41.4% to be of "moderate level 4(a" severity, while 30.6% of reactions were of "mild level 1" severity. About 30.8% of the ADRs were "definitely preventable" according to the modified Schumock and Thornton scale. Conclusion: ADRs are most important causes of morbidity and mortality and increase the economic burden on patient and society. By careful ADR monitoring, their incidence can be decreased.

    Objective The aim of this study was to analyze whether Jinlong capsule could decrease adverse reac-tions after transcatheter arterial chemoembolization (TACE) in patients with hepatocel ular carcinoma. Methods Eighty-two patients with hepatocel ular 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 oral y 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 dif erences in serum levels of amino-transferase, 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, respec-tively). However, there were no significant dif erences 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 hepatocel ular carcinoma patients treated with Jinlong capsule compared to untreated patients, suggesting possible beneficial ef ects exerted by Jinlong capsule on the reduction of TACE-induced liver damage, thereby improving liver function and, consequently, the quality of life.

    Purpose: To test whether mono- or dimeric X-ray contrast media (CM) may induce the de novo production of cysteinyl-leukotriens (cys-LT), that could contribute to allergic/allergy-like side effects. Materials and methods: Leukocytes from 39 patients receiving iopromide or iotrolan for routine CT-examination were analyzed for the production of cys-LT. Histamine levels were analyzed in plasma specimens. One patient with a positive history of a previous CM-reaction did not receive CM-injection. Results: Three patients of the iopromide and five of the iotrolan group showed adverse reactions. Reactors had increased cys-LT values in samples obtained before CM-injection induced by the positive control (anti-Fc{epsilon}RI antibodies) (6763.7 pg/ml {+-} 1367.3 versus 2299.8 pg/ml {+-} 399.2; p < 0.007). Patients with versus without CM-reaction did not differ significantly with respect to their histamine values before CM-administeration. In vitro iopromide (p < 0.0002) and iotrolan (p < 0.0008) induced significant cys-LT production as compared to IL-3 stimulation. In vivo both CM induced a significant increase 6 h after CM administration (p < 0.05). Conclusion: Our findings suggest that both CM seem to induce cys-LT production. As to whether the observed increased values in pre-dose samples of patients with as compared to those without reactions could contribute to identify high risk patients should be investigated in larger patient groups in future.

    Use of HMG-CoA reductase inhibitors in treating hypercholesterolemia is a well-established therapy.Presently,atorvastatin,fluvastatin,lovastatin,simvastatin and pravastatin are used clinically.Cerivastatin was pulled from the market in 2001 due to its higher risk of inducing rhabdomyolysis than all other drugs.Hepatotoxicity and rhabdomyolysis are the known adverse reactions by these drugs.However,the hepatotoxicity has been regarded to be mild,and is now referred to as transaminitis.Rhadomyolysis occurs in rare instances but is sometimes life threatening as a result of renal failure caused by myoglobinemia.The mechanism leading to rhabdomyolysis is unknown but in many of the reported cases,increased plasma concentratinos of thes drugs have been observed,most likely as a consequence of drug interaction.Inhibition of CYP 3A4 and UGT is believed to be the reason for this interaction.

    Full Text Available OBJECTIVE: To evaluate epidemiological features of post vaccine acute disseminated encephalomyelitis (ADEM by considering data from different pharmacovigilance surveillance systems. METHODS: The Vaccine Adverse Event Reporting System (VAERS database and the EudraVigilance post-authorisation module (EVPM were searched to identify post vaccine ADEM cases. Epidemiological features including sex and related vaccines were analysed. RESULTS: We retrieved 205 and 236 ADEM cases from the EVPM and VAERS databases, respectively, of which 404 were considered for epidemiological analysis following verification and causality assessment. Half of the patients had less than 18 years and with a slight male predominance. The time interval from vaccination to ADEM onset was 2-30 days in 61% of the cases. Vaccine against seasonal flu and human papilloma virus vaccine were those most frequently associated with ADEM, accounting for almost 30% of the total cases. Mean number of reports per year between 2005 and 2012 in VAERS database was 40±21.7, decreasing after 2010 mainly because of a reduction of reports associated with human papilloma virus and Diphtheria, Pertussis, Tetanus, Polio and Haemophilus Influentiae type B vaccines. CONCLUSIONS: This study has a high epidemiological power as it is based on information on adverse events having occurred in over one billion people. It suffers from lack of rigorous case verification due to the weakness intrinsic to the surveillance databases used. At variance with previous reports on a prevalence of ADEM in childhood we demonstrate that it may occur at any age when post vaccination. This study also shows that the diminishing trend in post vaccine ADEM reporting related to Diphtheria, Pertussis, Tetanus, Polio and Haemophilus Influentiae type B and human papilloma virus vaccine groups is most likely not [corrected] due to a decline in vaccine coverage indicative of a reduced attention to this adverse drug reaction.

    Purpose To review the current progress in epidemiology, etiology, clinical manifestation, and pathophysiology of severe cutaneous adverse drug reactions(SCADRs). Data sources Data were acquired by using Blackwell-Synergy, PubMed, original articles published in the main Chinese journals and related medical textbooks materials. Study-selection and date extraction Throughout the literature review 49 articles were selected. Results SCADRs cases are rare, however, the implication is life threatening with significant mortatity rates. Epidemiology studies have shown various incidences from different regions, gender, age, race and concurrent illness. There are typical signs and symptoms for each type of SCADRs, but this is not always so. Drugs associated with inducing SCADRs are anticonvulsants, antibiotics, NSAIDs and antirheumatic drugs. In some countries, especially in Asia, traditional drugs are offen the cause of SCADRs. Genetic polymorphisms and viral infections are predisposition factors of SCADRs. Patients with certain genetic alleles and underlying diseases are vulnerable to SCADRs. The exact pathogenesis of SCADRs is not well defined. Nonetheless, recent study showed that reactive metabolites and immunological processes have a significant role in SCADRs. Conclusions The different SCADRs reactions are attributed by different intrinsic factors, such as genetic polymorphisms, gender, age and race as well as extrinsic factors, such as underlying diseases. Different regions and culprit drugs also play a role in the various types of SCADRs.

    Full Text Available Treating cancer pain continues to possess a major challenge. Here, we report that a traditional Chinese medicine Xiao-Ai-Tong (XAT can effectively suppress pain and adverse reactions following morphine treatment in patients with bone cancer pain. Visual Analogue Scale (VAS and Quality of Life Questionnaire (EORTC QLQ-C30 were used for patient’s self-evaluation of pain intensity and evaluating changes of adverse reactions including constipation, nausea, fatigue, and anorexia, respectively, before and after treatment prescriptions. The clinical trials showed that repetitive oral administration of XAT (200 mL, bid, for 7 consecutive days alone greatly reduced cancer pain. Repetitive treatment with a combination of XAT and morphine (20 mg and 30 mg, resp. produced significant synergistic analgesic effects. Meanwhile, XAT greatly reduced the adverse reactions associated with cancer and/or morphine treatment. In addition, XAT treatment significantly reduced the proinflammatory cytokines interleukin-1β and tumor necrosis factor-α and increased the endogenous anti-inflammatory cytokine interleukin-10 in blood. These findings demonstrate that XAT can effectively reduce bone cancer pain probably mediated by the cytokine mechanisms, facilitate analgesic effect of morphine, and prevent or reduce the associated adverse reactions, supporting a use of XAT, alone or with morphine, in treating bone cancer pain in clinic.

    Full Text Available Background: N-acetylcysteine (NAC is the choice treatment for acetaminophen overdose. The main side effect of intravenous NAC therapy is anaphylaxis or anaphylactoid reactions. We investigated the prevalence of anaphylactoid or anaphylaxis reactions to IV-NAC therapy in acetaminophen poisoned patients with atopic disease. Methods: A case series antrograde and descriptive–analytic study was done on acetaminophen poisoned patients who treated with IV-NAC from September 2003 to September 2004 in Isfahan, Iran. Results: Of 173 infused IV-NAC patients, 77 patients (44.5% developed an anaphylactoid reaction. Its side effects was nausea and vomiting (n=49, 63.15%, flashing (n=23, 30.26%, bronchospasm (n=20, 26.31%, vertigo (n=18, 23.68%, skin rash (n=25, 32.36% and hypotension (n=12, 15.75%. Also, 71 patients (41% had history of atopic disease. Atopic diseases were asthma (n=12, 6.9%, atopic dermatitis (n=7, 4%, allergic rhinitis (n=5, 2.8% and allergic conjunctivitis (n=1, 0.5%. Among 71 atopic patients, 59 patients (83.13 % developed side effects to NAC. There was a relation between previous history of atopic disease and anaphylactoid reaction to NAC. Conclusions: We report substantially higher incidence of anaphylactoid reactions to IV-NAC than previous studies. Different atopic diseases must be considered as a risk factor in the development of side effects to IV-NAC-therapy.

    Full Text Available Abstract Objective: 1 To assess the adverse drug reactions of second line anti-tubercular drugs used to treat Multi-drug resistant Tuberculosis (MDR TB in central India on the basis of causality, severity and avoidability scales. 2 To study the relationship of type of MDR TB (primary or secondary and presence of diabetes mellitus (DM with mean smear conversion time. Material and Methods: A prospective, observational study was carried out on diagnosed multidrug resistant tuberculosis patients enrolled for DOTS‑Plus regimen at TB and Chest Disease Department from January to December 2012. They were followed for 9 months thereafter and encountered adverse drug reactions (ADRs were noted along with the time of sputum conversion. The data were analysed by Chi-square or Fisher’s exact test and unpaired student’s‘t’ test. Results: Total 64 ADRs were reported in 55 patients out of total 110 patients (n = 110. As per the Naranjo causality assessment of ADRs, 7 patients had “definite” causal relation, 45 had “probable” causal relation and 3 had “possible” causal relation with drugs of DOTS Plus regime. As per the Hartwig’s severity assessment scale, there were total 7 ADRs in Level 1, 6 in Level 2, 33 in Level 3 and 9 in Level 4. Hallas avoidability assessment scale divided the ADRs as 3 being “Definitely avoidable”, 26 “Possibly avoidable”, 23 “Not avoidable” and 3 “unevaluable”. . Mean sputum smear conversion time is significantly higher in patients with secondary type than that of primary type of MDR TB (p = 0.0001 and in patients with DM than those without DM (p <0.0001. Conclusion: ADRs were common in patients of MDR TB on DOTs-Plus drug regime. It was due to lack of availability of safer and equally potent drugs in DOTs-Plus drug regime compared to DOTS regime in non-resistant TB. The frequency and severity of ADRs can be reduced by strict vigilance about known and unknown ADRs, monitoring their laboratory and

    Drug reactions are a group of reactionary lesions generally show their manifestations in the oral cavity. The drug reactions may vary from local rashes to well-developed swellings in the oral cavity especially involving the gingiva. Most of the drug reactions are asymptomatic and commonly triggered from the active metabolite of a drug used for a long time. Nager syndrome is a group of acrofacial dysostosis that usually results in craniofacial and limb malformations. The craniofacial defects are very similar to the mandibulofacial dysostosis. A very early intervention is needed for the habilitation of the patient especially when it is concerned with speech and language development. This paper reports a case of a 32-year-old female with craniofacial, limb, and skeletal abnormalities along with a drug-induced gingival hyperplasia.

Older patients living in the community are particularly susceptible to ADRs, and are at an increased risk of ADR-related hospitalization. This review summarizes the available evidence on ADR-related hospital admission in older patients living in the community, with a particular focus on risk factors for ADRs leading to hospital admission and the need for a prediction tool for risk of ADR-related hospitalization in these individuals. The reported proportion of hospital admissions due to ADRs has ranged from 6% to 12% of all admissions in older patients. The main risk factors or predictors for ADR-related admissions were advanced age, polypharmacy, comorbidity, and potentially inappropriate medications. There is a clear need to design intervention strategies to prevent ADR-related hospitalization in older patients. To ensure the cost-effectiveness of such strategies, it would be necessary to target them to those older individuals who are at highest risk of ADR-related hospitalization. Currently, there are no validated tools to assess the risk of ADRs in primary care. There is a clear need to investigate the utility of tools to identify high-risk patients to target appropriate interventions toward prevention of ADR-related hospital admissions.

    Full Text Available Abstract Background Adverse drug reactions (ADR are a substantial cause of hospital admissions. We conducted a nationwide study to estimate the burden of hospital admissions for ADRs in Spain during a six-year period (2001-2006 along with the associated total health cost. Methods Data were obtained from the national surveillance system for hospital data (Minimum Basic Data Set maintained by the Ministry of Health and Consumer Affairs, and covering more than 95% of Spanish hospitals. From these admissions we selected all hospitalization that were code as drug-related (ICD-9-CM codes E, but intended forms of overdoses, errors in administration and therapeutics failure were excluded. The average number of hospitalizations per year, annual incidence of hospital admissions, average length of stay in the hospital, and case-fatality rate, were calculated. Results During the 2001-2006 periods, the total number of hospitalized patients with ADR diagnosis was 350,835 subjects, 1.69% of all acute hospital admissions in Spain. The estimated incidence of admissions due to ADR decreased during the period 2001-2006 (p Conclusions Approximately 1.69% of all acute hospital admissions were associated with ADRs. The rates were much higher for elderly patients. The total cost of ADR-related hospitalization to the Spanish health system is high and has increased between 2001 and 2006. ADRs are an important cause of admission, resulting in considerable use of national health system beds and a significant number of deaths.

    Results: A total of thirty-three cases (19 male and 14 females with complications to tattoos were registered over the period of one year. Thirty patients had their tattoo from an amateur while only three had from a professional tattooist. Twenty one (63.6% had acute complications and twelve (36.3% had chronic complications. Histpathological examination (HPE was done in ten of these cases and two refused biopsy. The findings were suggestive of lupus vulgaris (LV and foreign body granuloma (FBG in three each; chronic granulomatous changes in two, and spongiotic dermatitis (SD, and lichen planus hypertrophicus (LPH in one case each. Conclusions: Tattooing being largely unregulated has led to variability in contents of tattoo solution and inadequate sterilization during the procedure. This combined with lack of awareness, increases the chances of various adverse reactions. So it is extremely important to strictly regularize the tattoo practice and to increase awareness about tattoo complications among consumers, tattoo artists and dermatologists.

    Full Text Available Vaccines are administered to large population of healthy individuals, particularly to millions of infants every year, through national immunization programs. Although vaccines represent a good defense against some infectious diseases, their administration may be related with the development of adverse vaccine events (AVEs; therefore their use is continually monitored to detect these side effects. In the presents work, we reported the suspected AVEs recorded in 2012 in Calabria, Italy. We performed a retrospective study on report forms of patients that developed AVEs in Calabria from January 1, 2012 to December 31, 2012. Naranjo score was used to evaluate the association between AVEs and vaccines and only suspected AVEs definable as certain, probable, or possible were included in this analysis. During the study period, we evaluated 461 records of adverse drug reactions (ADRs and 18 (3.9% were probably induced by vaccination. AVEs were common in females (almost 77.7% and in children aged 0-3 years. The largest number of non-serious AVEs involved "skin and subcutaneous tissue disorders" and "general disorders and administration site conditions." In conclusion, we documented that in Calabria the total number of AVEs is very low and it may be useful to increase the pharmacovigilance culture in order to evaluate the safety of these products in large populations.

    Full Text Available OBJECTIVE: To report pediatric cases of paradoxical respiratory adverse drug reactions (ADRs after exposure to oral mucolytic drugs (carbocysteine, acetylcysteine that led to the withdrawal of licenses for these drugs for infants in France and then Italy. DESIGN: The study followed the recommendations of the European guidelines of pharmacovigilance for medicines used in the paediatric population. SETTING: Cases voluntarily reported by physicians from 1989 to 2008 were identified in the national French pharmacovigilance public database and in drug company databases. PATIENTS: The definition of paradoxical respiratory ADRs was based on the literature. Exposure to mucolytic drugs was arbitrarily defined as having received mucolytic drugs for at least 2 days (>200 mg and at least until the day before the first signs of the suspected ADR. RESULTS: The non-exclusive paradoxical respiratory ADRs reported in 59 paediatric patients (median age 5 months, range 3 weeks to 34 months, 98% younger than 2 years old were increased bronchorrhea or mucus vomiting (n = 27, worsening of respiratory distress during respiratory tract infection (n = 35, dyspnoea (n = 18, cough aggravation or prolongation (n = 11, and bronchospasm (n = 1. Fifty-one (86% children required hospitalization or extended hospitalization because of the ADR; one patient died of pulmonary oedema after mucus vomiting. CONCLUSION: Parents, physicians, pharmacists, and drug regulatory agencies should know that the benefit risk ratio of mucolytic drugs is at least null and most probably negative in infants according to available evidence.

    Full Text Available Rapid dissemination of information regarding adverse drug reactions is a key aspect for improving pharmacovigilance. There is a possibility that unknown adverse drug reactions will become apparent through post-marketing administration. Currently, although there have been studies evaluating the relationships between a drug and adverse drug reactions using the JADER database which collects reported spontaneous adverse drug reactions, an efficient approach to assess the association between adverse drug reactions of drugs with the same indications as well as the influence of demographics (e.g. gender has not been proposed.We utilized the REAC and DEMO tables from the May 2015 version of JADER for patients taking antidepressant drugs (SSRI, SNRI, and NaSSA. We evaluated the associations using association analyses with an apriori algorithm. Support, confidence, lift, and conviction were used as indicators for associations. The highest score in adverse drug reactions for SSRI was obtained for "aspartate aminotransferase increased", "alanine aminotransferase increased", with values of 0.0059, 0.93, 135.5, and 13.9 for support, confidence, lift and conviction, respectively. For SNRI, "international normalized ratio increased", "drug interaction" were observed with 0.0064, 1.00, 71.9, and NA. For NaSSA, "anxiety", "irritability" were observed with 0.0058, 0.80, 49.9, and 4.9. For female taking SSRI, the highest support scores were observed in "twenties", "suicide attempt", whereas "thirties", "neuroleptic malignant syndrome" were observed for male. Second, for SNRI, "eighties", "inappropriate antidiuretic hormone secretion" were observed for female, whereas "interstitial lung disease" and "hepatitis fulminant" were for male. Finally, for NaSSA, "suicidal ideation" was for female, and "rhabdomyolysis" was for male.Different combinations of adverse drug reactions were noted between the antidepressants. In addition, the reported adverse drug reactions

  7. [Diagnostic and therapeutic procedure for two popular but quite distinct adverse reactions to food - fructose malabsorption and histamine intolerance].

    Science.gov (United States)

    Reese, I

    2012-04-01

    Claiming to suffer from adverse food reactions is popular. In contrast to the classical food allergy, there are some pathomechanisms which are evidently dose-dependent. Thus the procedure in diagnosis and therapy must undoubtedly differ from the practice when food allergy is suspected or proven. Nevertheless many patients suffering from dose-dependent adverse reactions to food are given strict elimination diets, which is neither necessary nor helpful and decreases their quality of life broadly. This holds especially true for fructose malabsorption and histamine intolerance. For the latter, the term adverse reaction to ingested histamine is preferred, because histamine intolerance implies that symptoms are caused entirely by an enzyme defect. Why this is not very likely to be the only reason is discussed in this article. Both adverse reactions require an individual approach especially with regard to nutrition therapy. Therefore the task of diagnosis should be to establish an individual profile of tolerated and not tolerated foods taking into account that tolerance can greatly vary by meal composition, frequency and individual triggering factors. In view of this, therapeutic recommendations should not be based on the absolute quantities of the eliciting substance to be eliminated but on a feasible transfer into daily life. Thereby food restriction can be minimized and a high quality of life will be maintained.

    Adverse reactions to capecitabine-based chemotherapy limit full administration of cytotoxic agents. Likewise, genetic variations associated with capecitabine-related adverse reactions are associated with controversial results and a low predictive value. Thus, more evidence on the role of these variations is needed. We evaluated the association between nine polymorphisms in MTHFR, CDA, TYMS, ABCB1, and ENOSF1 and adverse reactions, dose reductions, treatment delays, and overall toxicity in 239 colorectal cancer patients treated with capecitabine-based regimens. The ABCB1*1 haplotype was associated with a high risk of delay in administration or reduction in the dose of capecitabine, diarrhea, and overall toxicity. CDA rs2072671 A was associated with a high risk of overall toxicity. TYMS rs45445694 was associated with a high risk of delay in administration or reduction in the dose of capecitabine, HFS >1 and HFS >2. Finally, ENOSF1 rs2612091 was associated with HFS >1, but was a poorer predictor than TYMS rs45445694. A score based on ABCB1-CDA polymorphisms efficiently predicts patients at high risk of severe overall toxicity (PPV, 54%; sensitivity, 43%) in colorectal cancer patients treated with regimens containing capecitabine. Polymorphisms in ABCB1, CDA, ENOSF1,and TYMS could help to predict specific and overall severe adverse reactions to capecitabine. PMID:25691056

    Full Text Available Identifying genetic factors responsible for serious adverse drug reaction (SADR is of critical importance to personalized medicine. However, genome-wide association studies are hampered due to the lack of case-control samples, and the selection of candidate genes is limited by the lack of understanding of the underlying mechanisms of SADRs. We hypothesize that drugs causing the same type of SADR might share a common mechanism by targeting unexpectedly the same SADR-mediating protein. Hence we propose an approach of identifying the common SADR-targets through constructing and mining an in silico chemical-protein interactome (CPI, a matrix of binding strengths among 162 drug molecules known to cause at least one type of SADR and 845 proteins. Drugs sharing the same SADR outcome were also found to possess similarities in their CPI profiles towards this 845 protein set. This methodology identified the candidate gene of sulfonamide-induced toxic epidermal necrolysis (TEN: all nine sulfonamides that cause TEN were found to bind strongly to MHC I (Cw*4, whereas none of the 17 control drugs that do not cause TEN were found to bind to it. Through an insight into the CPI, we found the Y116S substitution of MHC I (B*5703 enhances the unexpected binding of abacavir to its antigen presentation groove, which explains why B*5701, not B*5703, is the risk allele of abacavir-induced hypersensitivity. In conclusion, SADR targets and the patient-specific off-targets could be identified through a systematic investigation of the CPI, generating important hypotheses for prospective experimental validation of the candidate genes.

  14. Development of an adverse drug reaction risk assessment score among hospitalized patients with chronic kidney disease.

    Directory of Open Access Journals (Sweden)

    Fatemeh Saheb Sharif-Askari

    Full Text Available BACKGROUND: Adverse drug reactions (ADRs represent a major burden on the healthcare system. Chronic kidney disease (CKD patients are particularly vulnerable to ADRs because they are usually on multiple drug regimens, have multiple comorbidities, and because of alteration in their pharmacokinetics and pharmacodynamic parameters. Therefore, one step towards reducing this burden is to identify patients who are at increased risk of an ADR. OBJECTIVE: To develop a method of identifying CKD patients who are at increased risk for experiencing ADRs during hospitalisation. MATERIALS AND METHODS: Factors associated with ADRs were identified by using demographic, clinical and laboratory variables of patients with CKD stages 3 to 5 (estimated glomerular filtration rate, 10-59 ml/min/1.73 m2 who were admitted between January 1, 2012, and December 31, 2012, to the renal unit of Dubai Hospital. An ADR risk score was developed by constructing a series of logistic regression models. The overall model performance for sequential models was evaluated using Akaike Information Criterion for goodness of fit. Odd ratios of the variables retained in the best model were used to compute the risk scores. RESULTS: Of 512 patients (mean [SD] age, 60 [16] years, 62 (12.1% experienced an ADR during their hospitalisation. An ADR risk score included age 65 years or more, female sex, conservatively managed end-stage renal disease, vascular disease, serum level of C-reactive protein more than 10 mg/L, serum level of albumin less than 3.5 g/dL, and the use of 8 medications or more during hospitalization. The C statistic, which assesses the ability of the risk score to predict ADRs, was 0.838; 95% CI, 0.784-0.892. CONCLUSION: A score using routinely available patient data can be used to identify CKD patients who are at increased risk of ADRs.

    Dogs with cutaneous adverse food reactions (CAFR) often have specific IgE to food allergens. Egg white, which is majorly composed of ovomucoid, ovalbumin, ovotransferrin, and lysozyme, is a food allergen in dogs. Information of the IgE reactivity to purified egg white allergens supports accurate diagnosis and efficiency treatment in humans. However, to the best of our knowledge, there have been no studies on the IgE reactivity to purified egg white allergens in dogs. Here, we investigated the IgE reactivity to crude and purified allergens of hen egg white in dogs with CAFR. First, when we examined serum samples from 82 dogs with CAFR for specific IgE to crude egg white by ELISA, 9.8% (8/82) of the dogs with CAFR showed the IgE reactivity to crude egg white. We then used sera from the eight dogs with positive IgE reactivity to crude egg white to examine the IgE reactivity to four purified allergens, ovomucoid, ovalbumin, ovotransferrin, and lysozyme, by ELISA. We found that 75% (6/8) of the dogs showed IgE reactivity to both ovomucoid and ovalbumin, and that 37.5% (3/8) of the dogs showed IgE reactivity to ovotransferrin. None (0/8) showed IgE reactivity to lysozyme. Moreover, validating these results, the immunoblot analyses were performed using the sera of the three dogs showing the highest IgE reactivity to crude egg white. Both anti-ovomucoid and anti-ovalbumin IgE were detected in the sera of these dogs, while anti-ovotransferrin IgE was not detected. Considering these, ovomucoid and ovalbumin appears to be the major egg white allergens in dogs with CAFR. PMID:27436445

    Full Text Available Objectives: Adverse drug reactions (ADRs are an important cause of morbidity and mortality worldwide and generate high health costs. Therefore, the aims of this study were to determine the treatments which produce more ADRs in general population and the main symptoms they generate. Methods: An observational, cross-sectional study consisting in performing a self-rated questionnaire was carried out. 510 patients were asked about the treatments, illnesses and ADRs, they had suffered from. Results: 26.7% of patients had suffered from some ADR. Classifying patients according to the type of prescribed treatment and studying the number of ADR that they had, we obtained significant differences (p ≤ 0.05 for treatments against arthrosis, anemia and nervous disorders (anxiety, depression, insomnia. Moreover, determining absolute frequencies of these ADRs appearance in each treatment, higher frequencies were again for drugs against arthrosis (22.6% of patients treated for arthrosis suffered some ADR, anemia (14.28%, nerve disorders (13.44% and also asthma (16%. Regarding the symptoms produced by ADRs, the most frequent were gastrointestinal (60% of patients who suffered an ADR, had gastrointestinal symptoms and nervous alterations (dizziness, headache, sleep disturbances etc (24.6%. Conclusion: Therapeutic groups which produce more commonly ADRs are those for arthrosis, anemia, nervous disorders and asthma. In addition, symptoms which are generated more frequently are gastrointestinal and nervous problems. This is in accordance with the usual side effects of mentioned treatments. Health professionals should be informed about it, so that they would be more alert about a possible emergence of an ADR in these treatments. They also could provide enough information to empower patients and thus, they probably could detect ADR events. This would facilitate ADR detection and would avoid serious consequences generated to both patients' health and health economics.

    Non-interventional study in outpatient, contrast-enhanced CT: 1. to determine the extent of preventive measures for risk reduction of adverse drug reactions after contrast-enhanced CT examinations. 2. to prospectively determine the incidence and severity of adverse drug reactions occurring after administration of the iso-osmolar contrast medium iodixanol. 3. to determine a possible influence of preventive measures on the incidence/severity of adverse drug reactions. Evaluable documentation was provided for 9953 patients from 66 radiology centers across Germany. Patient characteristics, aspects of iodixanol administration, and adverse events with an at least 'possible' relationship were documented on a standardized case report form (CRF) and were evaluated up to seven days after contrast medium administration. About 55.5% of patients showed one or more risk factors (e.g. impaired renal function 4.4%, diabetes mellitus 8.5%, hypertension 20.6%). One third of the sites did not implement any preventive measures. Patients with a known risk for an allergy-like reaction were more likely to receive pharmacologic preventive treatment (0.5-50.5%). Oral hydration was the main preventive measure in patients with renal risk factors (<8%) followed by intravenous hydration (1%). Adverse drug reactions, mainly hypersensitivity reactions, occurred in 77 patients (0.74%), but were classified as serious in only 3 patients (0.03%). No statistically significant correlation between risk factors, preventive measures, and adverse reactions could be found. The use of preventive measures for CT examinations in this outpatient setting was generally low with risk patients being pre-medicated more often, depending on their history. In the routine outpatient setting, iso-osmolar iodixanol was very well tolerated in almost 10 000 patients undergoing diagnostic CT. The rate of acute and delayed adverse reactions was low. No correlation could be found between risk factors, preventive

    Full Text Available Ting Zhou, Saihua Lu, Xiufeng Liu, Ye Zhang, Feng XuDepartment of Clinical Pharmacology, Fengxian Hospital, Shanghai Jiao Tong University, Shanghai, People’s Republic of ChinaAbstract: Human serum albumin (HSA is an ideal natural colloid that has been widely used in clinical practice for supplemental albumin or as a plasma substitute during therapeutic plasma exchanges to redress hypoproteinemia. However, a paucity of well-designed clinical trials, a lack of a clear cut survival benefit, and frequent case reports of adverse drug reaction (ADR make the use of HSA controversial. This study aims to review and to comment on the reported ADRs of HSA in People's Republic of China, so as to provide the basis for rational HSA use in clinical settings. Data on the ADR case reports from HSA administration between January 1990 and December 2012 available from the China National Knowledge Infrastructure (CNKI database, Wanfang data (WF, and Chinese Biomedical Literature (CBM were reviewed. The reasons for using HSA, the types of ADRs, the causality of ADRs and the rationality for HSA administration were extracted and analyzed. In total, 61 cases of ADR reports were identified of which the primary disease of patients using HSA was malignant tumor (34.42%. The primary ADR was anaphylaxis (59.02%. Of the 61 cases, 30 were caused by irrational use of HSA. The most common irrational use was off-label use (56.67%, followed by inappropriate infusion rate. Therefore, we conclude that to avoid the occurrence of ADRs, guidelines for using HSA are needed to guarantee its rational use and HSA should be used strictly according to these guidelines. In addition, medical staff, including clinical pharmacists and nurses, should pay more attention to the patients who inject HSA to ensure its safe use in the clinic.Keywords: HSA, off-label use, ADR, plasma substitute, albumin, hypoproteinemia

    Full Text Available Background: Participation in social networking is commonplace and social media is transforming both health and health related research. Of the various social media platforms, Twitter must be considered a platform for rapid and immediate communication. There has been considerable national and international media coverage reporting a number of adverse incidents in the Irish maternity services. The media coverage of these adverse incidents, most recently about a cluster of perinatal deaths, stimulated much public debate including debate online. Aim: Our study aimed to explore the Twitter status updates, and subsequent responses, relating to a number of perinatal deaths which occurred in a maternity unit with approximately 2,000 births per year. Method: As this study examined Twitter status updates in relation to reported perinatal death a mixed methods approach was adopted. Firstly, status updates in English were searched utilising the Twitter search function on its website. A search was undertaken on all public status updates from January 29th 2014 to March 31st 2014 relating to the perinatal deaths. Data were quantitatively analysed in order to assess the frequency of status updates, the demographic profiles of users and to ascertain the potential reach of the status updates. Secondly qualitative analysis was employed to generate themes from the content that twitter users shared publically. Results: From January 29th 2014 to March 31st 2014, 3,577 Twitter status updates from 1,276 profiles relating to the perinatal deaths were identified. Of these, 54.1% (n=1615 were tweets, 38.9% (n=1392 were retweets and 15.9% (n=570 were replies. Over one third of all updates (36.8%; n=1317 were from profiles which identified the user as either a media outlet or media personnel. One in 10 (11.8%; 424 status updates were by those who self-identified as a parent. Twitter was not utilised as a platform by any healthcare authority to release a statement in

    Adverse event (AE) reporting in oncology has evolved from informal descriptions to a highly systematized process. The Common Terminology Criteria for Adverse Events (CTCAE) is the predominant system for describing the severity of AEs commonly encountered in oncology clinical trials. CTCAE clinical descriptors have been developed empirically during more than 30 years of use. The method of data collection is clinician based. Limitations of the CTC system include potential for incomplete reporting and limited guidance on data analysis and presentation methods. The Medical Dictionary for Regulatory Activities (MedDRA) is a comprehensive medical terminology system used for regulatory reporting and drug labeling. MedDRA does not provide for severity ranking of AEs. CTC-based data presentations are the primary method of AE data reporting used in scientific journals and oncology meetings. Patient-reported outcome instruments (PROs) cover the subjective domain of AEs. Exploratory work suggests PROs can be used with a high degree of patient engagement and compliance. Additional studies are needed to determine how PROs can be used to complement current AE reporting systems. Potential models for integrating PROs into AE reporting are described in this review. AE reporting methods will continue to evolve in response to changing therapies and growing interest in measuring the impact of cancer treatment on health status. Although integration of PROs into AE reporting may ultimately improve the comprehensiveness and quality of collected data, it may also increase the administrative burden and cost of conducting trials. Therefore, care must be used when developing health outcomes and safety data collection plans. PMID:17991931

These toxicities are manifested as damage to normal tissues and organs in the radiation field. In recognition of the substantial variation in the intrinsic response of individuals to radiation, an effort began approximately 10 years ago to discover the genetic markers, primarily SNPs, which are associated with susceptibility for the development of these adverse responses to ra...

    2013-01-01

    Background The concomitant use of multiple medications by elderly patients with hypertension is a relatively common and growing phenomenon in Japan. This has been attributed to several factors, including treatment guidelines recommending prescription of multiple medications and a continuing increase in the elderly population with multiple comorbidities. Objective This study was aimed at investigating the association between polypharmacy, defined as the concomitant use of five or more medications, and risk of adverse drug reaction (ADR) in elderly Japanese hypertensive patients to examine the hypothesis that risk of ADR increases with the administration of an increasing number of co-medications. Methods Using a retrospective cohort design, the data regarding all hypertensive patients aged 65 years or older were extracted from the Risk/Benefit Assessment of Drugs – Analysis and Response Council antihypertensive medication database. The data were reviewed for classification of patients into one of three groups according to drug use at the initiation of therapy – a monotherapy group composed of patients who had taken the investigated drug only, a co-medication group composed of patients who had taken the investigated drug and a maximum of three other medications, and a polypharmacy group composed of patients who had taken the investigated drug and four or more other medications – and determination of the number of ADR events experienced. Estimated rate ratios (RRs) and 95% confidence intervals (CIs) were calculated using a Poisson regression model adjusted for drug category and patient age and sex. Various sensitivity analyses were performed to confirm the robustness of the study findings. Results Of 61,661 elderly Japanese patients (men, 41.8%; 75 years or older, 35.1%) registered in the database, 2491 patients (4.0%) experienced a total of 3144 ADR events during the study period. The rate of ADR per 10,000 person-days was 2.0 for the monotherapy group, 5.1 for

    2016-01-01

    Background We performed a systematic review to assess whether we can quantify the underreporting of adverse events (AEs) in the published medical literature documenting the results of clinical trials as compared with other nonpublished sources, and whether we can measure the impact this underreporting has on systematic reviews of adverse events. Methods and Findings Studies were identified from 15 databases (including MEDLINE and Embase) and by handsearching, reference checking, internet searches, and contacting experts. The last database searches were conducted in July 2016. There were 28 methodological evaluations that met the inclusion criteria. Of these, 9 studies compared the proportion of trials reporting adverse events by publication status. The median percentage of published documents with adverse events information was 46% compared to 95% in the corresponding unpublished documents. There was a similar pattern with unmatched studies, for which 43% of published studies contained adverse events information compared to 83% of unpublished studies. A total of 11 studies compared the numbers of adverse events in matched published and unpublished documents. The percentage of adverse events that would have been missed had each analysis relied only on the published versions varied between 43% and 100%, with a median of 64%. Within these 11 studies, 24 comparisons of named adverse events such as death, suicide, or respiratory adverse events were undertaken. In 18 of the 24 comparisons, the number of named adverse events was higher in unpublished than published documents. Additionally, 2 other studies demonstrated that there are substantially more types of adverse events reported in matched unpublished than published documents. There were 20 meta-analyses that reported the odds ratios (ORs) and/or risk ratios (RRs) for adverse events with and without unpublished data. Inclusion of unpublished data increased the precision of the pooled estimates (narrower 95

    Full Text Available Background/Aim. The provision of safe healthcare is considered a priority in European Union (EU member states. Along with other preventative measures in healthcare, the EU also strives to eliminate the “causes of harm to human health”. The aim of this survey was to determine whether safety culture, supervisors and communication between co-workers influence the number of adverse event reports submitted to the heads of clinical departments and to the management of an institution. Methods. This survey is based on cross-sectional analysis. It was carried out in the largest Slovenian university hospital. We received 235 completed questionnaires. Respondents included professionals in the fields of nursingcare, physiotherapy, occupational therapy and radiological technology. Results. Safety culture influences the number of adverse event reports submitted to the head of a clinical department from the organizational point of view. Supervisors and communication between co-workers do not influence the number of adverse event reports. Conclusion. It can be concluded that neither supervisors nor the level of communication between co-workers influence the frequency of adverse event reporting, while safety culture does influence it from an organizational point of view. The presumed factors only partly influence the number of submitted adverse event reports, thus other causes of under-reporting must be sought elsewhere.

    Although cancer treatment with radiation can produce high cure rates, adverse effects often result from radiotherapy. These toxicities are manifested as damage to normal tissues and organs in the radiation field. In recognition of the substantial variation in the intrinsic response of individuals to radiation, an effort began approximately 10 years ago to discover the genetic markers, primarily SNPs, which are associated with susceptibility for the development of these adverse responses to radiation therapy. The goal of this research is to identify the SNPs that could serve as the basis of an assay to predict which cancer patients are most likely to develop complications resulting from radiotherapy. This would permit personalization and optimization of the treatment plan for each cancer patient. PMID:21332318

    Reneé de Waal

    Full Text Available BACKGROUND: Lipoatrophy and/or central fat gain are observed frequently in patients on antiretroviral therapy (ART. Both are assumed to be antiretroviral adverse drug reactions. METHODS: We conducted a systematic review to determine whether fat loss or gain was more common in HIV-infected patients on ART than in uninfected controls; was associated with specific antiretrovirals; and would reverse after switching antiretrovirals. RESULTS: Twenty-seven studies met our inclusion criteria. One cohort study reported more lipoatrophy, less subcutaneous fat gain, but no difference in central fat gain in HIV-infected patients on ART than in controls. Randomised controlled trials (RCTs showed more limb fat loss (or less fat gain with the following regimens: stavudine (versus other nucleoside reverse transcriptase inhibitors (NRTIs; efavirenz (versus protease inhibitors (PIs; and NRTI-containing (versus NRTI-sparing. RCTs showed increased subcutaneous fat after switching to NRTI-sparing regimens or from stavudine/zidovudine to abacavir/tenofovir. There were no significant between-group differences in trunk and/or visceral fat gain in RCTs of various regimens, but results from efavirenz versus PI regimens were inconsistent. There was no significant between-group differences in central fat gain in RCTs switched to NRTI-sparing regimens, or from PI-containing regimens. CONCLUSIONS: There is clear evidence of a causal relationship between NRTIs (especially thymidine analogues and lipoatrophy, with concomitant PIs possibly having an ameliorating effect or efavirenz causing additive toxicity. By contrast, central fat gain appears to be a consequence of treating HIV infection, because it is not different from controls, is not linked to any antiretroviral class, and doesn't improve on switching.

Oral reactions to these agents are not specific and might present with various clinical oral findings. Detailed medical history is a key to the proper diagnosis of these lesions and fortunately other diagnostic procedures are rarely needed. Lesions are usually managed with elimination of the offending agent and with topical steroids. In more severe cases systemic steroids should be applied.

    2008-11-01

    The presence of human heterophilic antibodies against horse immunoglobulins (HHA-HI) was determined by ELISA in sera from healthy volunteers and from patients who received equine antivenom for therapy of snake bite envenoming. These patients were selected from two independent clinical studies: one in Colombia in which patients received antivenom constituted by whole IgG (n=25); and the other in Brazil where an antivenom constituted by F(ab')(2) fragments was administered (n=31). Results show that healthy volunteers have antibodies, mainly of the IgG class, able to react with whole equine IgG. Additionally, patients have IgG antibodies that react both with whole equine IgG and F(ab')(2) fragments. In both clinical studies, no significant differences were observed in the HHA-HI titres between the patients who presented early adverse (anaphylactoid) reactions and those who did not develop them. In addition, no variation in titre was observed in samples collected before and after antivenom administration. These results do not support the hypothesis that the incidence of early adverse reactions to antivenom administration correlates with the titre of HHA-HI in the serum of patients. Nevertheless, participation of these antibodies as part of a multifactorial pathogenic mechanism associated with these reactions cannot be ruled out. PMID:18561967

    Full Text Available Background: Epilepsy is a chronic neurological disorder requiring long-term treatment. Seizure control requires adequate blood levels of anti-seizure drugs. Carbarmazepine is one of the most prescribed antiepileptic drugs in Nigeria. This study was carried out to investigate the correlation between serum levels of carbamazepine and seizure control and adverse drug reactions among epileptics in Ibadan, Nigeria. Methods: In a cross-sectional study, sixty-nine patients with confirmed diagnosis of epilepsy who had been on treatment with carbamazepine alone or in combination with phenytoin for at least one month were enrolled into the study and divided into two groups based on seizure control. Drug level in pre-dose (steady state venous blood was analyzed using high performance liquid chromatography. Result: The mean serum concentration of carbamazepine (CBZ and carbamazepine-epoxide (CBZ-EP was 13.5±9.3ìg/mL and 6.34±12.61ìg/mL respectively. Patients with good seizure control had mean serum CBZ concentration of 12.7 ± 9.2ìg/mL versus 15.02 ± 9.7ìg/mL among patients with poor seizure control (P=0.33. The serum concentration of CBZ-EP in patients with good seizure control was 8.05 ± 15.2ìg/mL while it was 3.11 ± 3.5ìg/mL in the second group (P=0.122. Drowsiness was the commonest adverse drug reaction (26.1% and it did not necessitate withdrawal of the drug. Conclusion The study showed that serum level of carbamazepine does not correlate with seizure control and adverse drug reactions.

    Full Text Available INTRODUCTION: The Global Programme to Eliminate Lymphatic Filariasis was launched with the goal of eliminating this disease via the annual mass drug administration (MDA of a single dose of antifilarial drugs. Adverse drug reactions following MDA are a major factor of poor treatment adherence in several countries. This study assessed the occurrence of adverse drug reactions (ADRs following the first round of mass treatment in two communities treated with different dosages of diethylcarbamazine (DEC in the City of Recife, Brazil. METHODS: Population-based cross-sectional surveys were conducted in a random sample of the population living in both communities (Areas I and II. The dose of DEC recommended by the WHO (6mg/kg was calculated based on the individual's weight-for-age. In Area II, weight differences between the genders were also considered when determining dosage. Data were obtained through interviews conducted in the first 12 to 48h and on the 5th day after MDA during household visits. RESULTS: A total of 487 and 365 individuals were interviewed in Areas I and II, respectively. The prevalence of ADRs in Area I (23.6; 95%CI: 19.1-29.5 was higher than in Area II (16.2; 95%CI:11.9-21.5(p=0.0078. The prevalence of ADRs among females was higher than in males in Area I (p=0.0021. In Area II, no significant difference between the genders was observed (p=0.1840. Age was not associated with ADRs in either area. CONCLUSIONS: Adjusting MDA dosage schedules according to weight-for-age and sex may be may contribute to reduce the occurrence of adverse drug reactions in the population.

    As a new dosage form, TCM injection is commonly used in clinical practice. But the increasing events of adverse drug reactions (ADRs) could even seriously endanger patients' lives. The causes of TCM injection inducing ADRs might be the unstable quality of preparation; the irrational clinical use and operation; the sensitive physique of patient and the change of patients' primary illness, etc. For preventing the occurrence of ADRs, based on guaranteeing the stable quality of product, putting stress on accurate usages and normalized operations in clinical practice, enhancing the monitor on ADRs and the precautionary awareness in medical units are very important.

    Full Text Available OBJECTIVE: Adverse event reports (AERs submitted to the US Food and Drug Administration (FDA were reviewed to assess the muscular and renal adverse events induced by the administration of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA reductase inhibitors (statins and to attempt to determine the rank-order of the association. METHODS: After a revision of arbitrary drug names and the deletion of duplicated submissions, AERs involving pravastatin, simvastatin, atorvastatin, or rosuvastatin were analyzed. Authorized pharmacovigilance tools were used for quantitative detection of signals, i.e., drug-associated adverse events, including the proportional reporting ratio, the reporting odds ratio, the information component given by a Bayesian confidence propagation neural network, and the empirical Bayes geometric mean. Myalgia, rhabdomyolysis and an increase in creatine phosphokinase level were focused on as the muscular adverse events, and acute renal failure, non-acute renal failure, and an increase in blood creatinine level as the renal adverse events. RESULTS: Based on 1,644,220 AERs from 2004 to 2009, signals were detected for 4 statins with respect to myalgia, rhabdomyolysis, and an increase in creatine phosphokinase level, but these signals were stronger for rosuvastatin than pravastatin and atorvastatin. Signals were also detected for acute renal failure, though in the case of atorvastatin, the association was marginal, and furthermore, a signal was not detected for non-acute renal failure or for an increase in blood creatinine level. CONCLUSIONS: Data mining of the FDA's adverse event reporting system, AERS, is useful for examining statin-associated muscular and renal adverse events. The data strongly suggest the necessity of well-organized clinical studies with respect to statin-associated adverse events.

    Edward Chia-Cheng Lai

    Full Text Available PURPOSE: Previous studies have demonstrated sulpiride to be significantly more effective than haloperidol, risperidone and olanzapine in schizophrenic treatment; however, only limited information is available on the potential risks associated with sulpiride treatment. This study attempts to provide information on the potential risks of sulpiride treatment of schizophrenia, especially with regard to unexpected adverse effects. MATERIALS AND METHODS: Patients with schizophrenia aged 18 and older, newly prescribed with a single antipsychotic medication from the National Health Insurance Research Database of Taiwan in the period from 2003 to 2010 were included. A within-subject comparison method, prescription sequence symmetry analysis (PSSA was employed to efficiently identify potential causal relationships while controlling for potential selection bias. RESULTS: A total of 5,750 patients, with a mean age of 39, approximately half of whom were male, constituted the study cohort. The PSSA found that sulpiride was associated with EPS (adjusted SR, 1.73; 95% CI, 1.46-2.06 and hyperprolactinemia (12.04; 1.59-91.2. In comparison, EPS caused by haloperidol has a magnitude of 1.99 when analyzed with PSSA, and hyperprolactinemia caused by amisulpride has a magnitude of 8.05, respectively. Another finding was the unexpected increase in the use of stomatological corticosteroids, emollient laxatives, dermatological preparations of corticosteroids, quinolone antibacterials, and topical products for joint and muscular pain, after initiation of sulpiride treatment. CONCLUSIONS: We found sulpiride to be associated with an increased risk of EPS and hyperprolactinemia, and the potential risk could be as high as that induced by haloperidol and amisulpride, respectively. Additionally, our study provides grounds for future investigations into the associations between sulpiride and the increased use of additional drugs for managing adverse effects, including

    This study examined different indicators of each stage of Maillard reaction under adverse storage conditions in a system with whey proteins and lactose or glucose. The analysis of lysine loss by the o-phthaldialdehyde method can be considered a good indicator of the early stage, showing considerable differences in reactivity when systems with mono and disaccharides were analyzed. Capillary electrophoresis proved to be a sensitive method for evaluating the extent of glycosylation of the native proteins, providing valuable information when the loss of lysine was not significant. The estimation of the Amadori compound from the determination of total 5-hydroxymethyl-2-furfuraldehyde would have correlate well with reactive lysine content if the advanced stages of the reaction had not been reached. For assessing the occurrence of the intermediate and final stages, the measurement of free 5-hydroxymethyl-2-furfuraldehyde and color, proved not to be suitable for storage conditions. PMID:27542493

    Full Text Available Background: Adverse cutaneous drug reactions (ACDRs are caused by a wide variety of agents. Aims: Our objective was to ascertain the clinical spectrum of ACDRs and the causative drugs in this part of India and to find any risk factors. Methods: Ninety patients with adverse cutaneous drug reactions were recruited for this study during 2001-2003. Hematological and biochemical investigations were done in all of them. The VDRL and HIV (ELISA tests were performed where the underlying risk factors were present. Patch testing, intradermal testing and oral provocation tests were done wherever feasible. Results: The mean age of the patients with cutaneous drug eruptions was 37.06 years. Most of them (52.2% were in the age group of 20-39 years. The male to female ratio was 0.87: 1. The most common eruptions observed were fixed drug eruption (31.1% and maculopapular rash (12.2%, and the most common causes were co-trimoxazole (22.2% and dapsone (17.7%. Conclusion: The pattern of ACDRs and the drugs causing them is remarkably different in our population. Knowledge of these drug eruptions, the causative drugs and the prognostic indicators is essential for the clinician.

    We analyzed the cases of side effects due to antipsychotics reported to Japan's Pharmaceuticals and Medical Devices Agency (PMDA) from Jan. 2004 to Dec. 2012. We used the Japanese Adverse Drug Event Report Database (JADER) and analyzed 136 of 216,945 cases using the defined terms. We also checked the cardiac adverse effects listed in the package inserts of the antipsychotics involved. We found cases of Ikr blockade resulting in sudden death (49 cases), electrocardiogram QT prolonged (29 cases), torsade de pointes (TdP, 19 cases), ventricular fibrillation (VF, 10 cases). M2 receptor blockade was observed in tachycardia (8 cases) and sinus tachycardia (3 cases). Calmodulin blockade was involved in reported cardiomyopathy (3 cases) and myocarditis (1 case). Multiple adverse events were reported simultaneously in 14 cases. Our search of package inserts revealed warnings regarding electrocardiogram QT prolongation (24 drugs), tachycardia (23), sudden death (18), TdP (14), VF (3), myocarditis (1) and cardiomyopathy (1). We suggest that when an antipsychotic is prescribed, the patient should be monitored regularly with ECG, blood tests, and/or biochemical tests to avoid adverse cardiac effects. PMID:25069255

    Aspirin-exacerbated respiratory disease (AERD) is an adult-onset condition that manifests as asthma, rhinosinusitis/nasal polyps, and sensitivity to aspirin and other cyclooxygenase-1 (COX-1)-inhibitor nonsteroidal anti-inflammatory drugs (NSAIDs). There is no cross-sensitivity to highly selective COX-2 inhibitors. AERD is chronic and does not improve with avoidance of COX-1 inhibitors. The diagnosis of AERD is made through provocative challenge testing. Following a positive aspirin challenge, patients can be desensitized to aspirin and NSAIDs. The desensitized state can be maintained indefinitely with continued daily administration. After desensitization, there is an approximately 48-hour refractory period to adverse effects from aspirin. The pathogenesis of AERD remains unknown, but these patients have been shown to have multiple abnormalities in arachidonic acid metabolism and in cysteinyl leukotriene 1 receptors. AERD patients can take up to 650 mg of acetaminophen for analgesic or antipyretic relief. Patients can also use weak COX-1 inhibitors, such as sodium salicylate or choline magnesium trisalicylate. Treatment of AERD patients with antileukotriene medications has been helpful but not preferential when compared with non-AERD patients. An alternative treatment for many AERD patients is aspirin desensitization. This is particularly effective in reducing upper-airway mucosal congestion, nasal polyp formation, and systemic steroids.

    AIM: To compare the findings of a survey undertaken by us in 2002 regarding steroid premedication given in radiology departments to reduce the risk of adverse reactions in patients at increased risk of intravascular contrast media reactions with a similar survey published in 1994 by R. Seymour et al. The high risk patients considered in our survey were patients with history of asthma, drug allergies, hay fever and eczema. MATERIALS AND METHODS: A total of 225 questionnaires were sent to the consultant in charge for audit for radiology departments from the list given by the Royal College of Radiologists. 175 of the 225 questionnaires were returned (response rate 77.8%) and of these 172 were analysed with respect to the type, dose and duration of steroids. RESULTS: Compared to the survey in 1994, it was found that the number of departments who use steroid cover for all category of risk factors had increased compared to previous survey (73.8% in 2002 versus 55.3% in 1994 (p=0.001). There is now almost universal use of non-ionic contrast 98.8% versus 82.4% in 1994 (p=0.001). There is no agreed policy among radiology departments for the need or the dose or duration of steroid cover. CONCLUSION: Despite the more widespread use of non-ionic contrast media, the use of steroid premedication has increased which is contrary to what is expected as the incidence of adverse reaction to non ionic media is less than ionic contrast media.

    A new statistical methodology is developed for the analysis of spontaneous adverse event (AE) reports from post-marketing drug surveillance data. The method involves both empirical Bayes (EB) and fully Bayes estimation of rate multipliers for each drug within a class of drugs, for a particular AE, based on a mixed-effects Poisson regression model. Both parametric and semiparametric models for the random-effect distribution are examined. The method is applied to data from Food and Drug Administration (FDA)'s Adverse Event Reporting System (AERS) on the relationship between antidepressants and suicide. We obtain point estimates and 95 per cent confidence (posterior) intervals for the rate multiplier for each drug (e.g. antidepressants), which can be used to determine whether a particular drug has an increased risk of association with a particular AE (e.g. suicide). Confidence (posterior) intervals that do not include 1.0 provide evidence for either significant protective or harmful associations of the drug and the adverse effect. We also examine EB, parametric Bayes, and semiparametric Bayes estimators of the rate multipliers and associated confidence (posterior) intervals. Results of our analysis of the FDA AERS data revealed that newer antidepressants are associated with lower rates of suicide adverse event reports compared with older antidepressants. We recommend improvements to the existing AERS system, which are likely to improve its public health value as an early warning system. PMID:18404622

    Purpose Serious adverse drug event (sADE) reporting to Institutional Review Boards (IRB) is essential to ensure pharmaceutical safety. However, the quality of these reports has not been studied. Safety reports are especially important for cancer drugs that receive accelerated Food and Drug Administration approval, like imatinib, as preapproval experience with these drugs is limited. We evaluated the quality, accuracy, and completeness of sADE reports submitted to an IRB. Experimental Design sADE reports submitted to an IRB from 14 clinical trials with imatinib were reviewed. Structured case report forms, containing detailed clinical data fields and a validated causality assessment instrument, were developed. Two forms were generated for each ADE, the first populated with data abstracted from the IRB reports, and the second populated with data from the corresponding clinical record. Completeness and causality assessments were evaluated for each of the two sources, and then compared. Accuracy (concordance between sources) was also assessed. Results Of 115 sADEs reported for 177 cancer patients to the IRB, overall completeness of adverse event descriptions was 2.4-fold greater for structured case report forms populated with information from the clinical record versus the corresponding forms from IRB reports (95.0% versus 40.3%, P < 0.05). Information supporting causality assessments was recorded 3.5-fold more often in primary data sources versus IRB adverse event descriptions (93% versus 26%, P < 0.05). Some key clinical information was discrepant between the two sources. Conclusions The use of structured syndrome-specific case report forms could enhance the quality of reporting to IRBs, thereby improving the safety of pharmaceuticals administered to cancer patients.

    2011-01-01

    Full Text Available An adverse drug reaction (ADR is defined by the World Health Organization as a noxious, unintended, and undesired drug effect, when used for therapeutic purposes in humans. ADRs to anti-epileptic drugs (AEDs significantly impact the quality of life of people with epilepsy and account for a little less than half of all recorded treatment failures with AEDs. Hence prevention and early recognition of ADRs constitute an important aspect of management of epilepsy. Recent developments have improved our ability to predict and hence potentially prevent the occurrence of some of the serious ADRs to AEDs. One example is the potential prediction of the risk of severe cutaneous hypersensitivity reactions including Stevens Johnson syndrome and toxic epidermal necrolysis by testing for expression of HLA BFNx011502 allele in people of Asian origin who are prescribed carbamazepine. The association between HLA BFNx011502 expression and carbamazepine skin reactions has been documented in India but the role of HLA testing in Indian populations needs to be clarified in larger studies across different ethnic groups within the country.

    Full Text Available Abstract Background A significant proportion of surgical patients are unintentionally harmed during their hospital stay. Root Cause Analysis (RCA aims to determine the aetiology of adverse incidents that lead to patient harm and produce a series of recommendations, which would minimise the risk of recurrence of similar events, if appropriately applied to clinical practice. A review of the quality of the adverse incident reporting system and the RCA of serious adverse incidents at the Department of Surgery of Ninewells hospital, in Dundee, United Kingdom was performed. Methods The Adverse Incident Management (AIM database of the Department of Surgery of Ninewells Hospital was retrospectively reviewed. Details of all serious (red, sentinel incidents recorded between May 2004 and December 2009, including the RCA reports and outcomes, where applicable, were reviewed. Additional related information was gathered by interviewing the involved members of staff. Results The total number of reported surgical incidents was 3142, of which 81 (2.58% cases had been reported as red or sentinel. 19 of the 81 incidents (23.4% had been inappropriately reported as red. In 31 reports (38.2% vital information with regards to the details of the adverse incidents had not been recorded. In 12 cases (14.8% the description of incidents was of poor quality. RCA was performed for 47 cases (58% and only 12 cases (15% received recommendations aiming to improve clinical practice. Conclusion The results of our study demonstrate the need for improvement in the quality of incident reporting. There are enormous benefits to be gained by this time and resource consuming process, however appropriate staff training on the use of this system is a pre-requisite.

    We have applied intracavitary hyperthermo-radiotherapy to the treatment of various cancers. In this study, early response and acute reaction were analyzed. Eighteen patients treated with intracavitary hyperthermo-radiotherapy were as follows; 4 of esophageal cancer, 6 of uterine cervical cancer, 3 of rectal cancer, and 5 of others. Intracavitary hyperthermia was performed with Endoradiotherm 100A (OLYMPUS) once or twice a week with a total number of heating sessions ranging from 2 to 12 times. The heating was started just after the irradiation, and the temperature measured at the surface of applicator was kept at 42-44 deg C during the treatment for 30-40 min. External irradiation was performed in the majority of these 18 patients. Nine cases achieved complete response (CR), 6 cases did partial response (PR) and 3 cases were no change (NC). Of CR 9 cases, 6 cases showed 2-year local control. There were 2 esophageal tumors, 2 cervical tumors, 1 rectal tumor, and 1 vaginal stump tumor among 2-year local control cases. The treatment was interrupted in 2 patients from severe local pain during the heating. Severe vaginal mucositis occurred in 4 stump tumors. Intracavitary hyperthermoradiotherapy showed good early response for esophageal cancer and stump tumor. The advantages of intracavitary hyperthermia might be the reliability of heating for the treatment of localized tumors. (author)

    Idiosyncratic drug reactions (IDRs) represent a major health problem, as they are unpredictable, often severe and can be life threatening. The low incidence of IDRs makes their detection during drug development stages very difficult causing many post-marketing drug withdrawals and black box warnings. The fact that IDRs are always not predictable based on the drug's known pharmacology and have no clear dose-effect relationship with the culprit drug renders diagnosis of IDRs very challenging, if not impossible, without the aid of a reliable diagnostic test. The drug provocation test (DPT) is considered the gold standard for diagnosis of IDRs but it is not always safe to perform on patients. In vitro tests have the advantage of bearing no potential harm to patients. However, available in vitro tests are not commonly used clinically because of lack of validation and their complex and expensive procedures. This review discusses the current role of in vitro diagnostic testing for diagnosis of IDRs and gives a brief account of their technical and mechanistic aspects. Advantages, disadvantages and major challenges that prevent these tests from becoming mainstream diagnostic tools are also discussed here. PMID:25199801

    Adverse drug reaction (ADR) is of great importance to both regulatory agencies and the pharmaceutical industry. Various techniques, such as quantitative structure-activity relationship (QSAR) and animal toxicology, are widely used to identify potential risks during the preclinical stage of drug development. Despite these efforts, drugs with safety liabilities can still pass through safety checkpoints and enter the market. This situation raises the concern that conventional chemical structure analysis and phenotypic screening are not sufficient to avoid all clinical adverse events. Genomic expression data following in vitro drug treatments characterize drug actions and thus have become widely used in drug repositioning. In the present study, we explored prediction of ADRs based on the drug-induced gene-expression profiles from cultured human cells in the Connectivity Map (CMap) database. The results showed that drugs inducing comparable ADRs generally lead to similar CMap expression profiles. Based on such ADR-gene expression association, we established prediction models for various ADRs, including severe myocardial and infectious events. Drugs with FDA boxed warnings of safety liability were effectively identified. We therefore suggest that drug-induced gene expression change, in combination with effective computational methods, may provide a new dimension of information to facilitate systematic drug safety evaluation.

    Full Text Available Prophylactic antipyretic administration decreases the post-vaccination adverse reactions. Recent study finds that they may also decrease the antibody responses to several vaccine antigens. This systematic review aimed to assess the evidence for a relationship between prophylactic antipyretic administration, post-vaccination adverse events, and antibody response in children.A systematic search of major databases including MEDLINE and EMBASE was carried out till March 2014. Randomized controlled trials (RCTs comparing prophylactic antipyretic treatment versus placebo post-vaccination in children ≤ 6 years of age were included. Two reviewers independently applied eligibility criteria, assessed the studies for methodological quality, and extracted data [PROSPERO registration: CRD42014009717].Of 2579 citations retrieved, a total of 13 RCTs including 5077 children were included in the review. Prophylactic antipyretic administration significantly reduced the febrile reactions (≥ 38.0 °C after primary and booster vaccinations. Though there were statistically significant differences in the antibody responses between the two groups, the prophylactic PCM group had what would be considered protective levels of antibodies to all of the antigens given after the primary and booster vaccinations. No significant difference in the nasopharyngeal carriage rates (short-term and long-term of H. influenzae or S. pneumoniae serotypes was found between the prophylactic and no prophylactic PCM group. There was a significant reduction in the local and systemic symptoms after primary, but not booster vaccinations.Though prophylactic antipyretic administration leads to relief of the local and systemic symptoms after primary vaccinations, there is a reduction in antibody responses to some vaccine antigens without any effect on the nasopharyngeal carriage rates of S. pneumoniae & H. influenza serotypes. Future trials and surveillance programs should also aim at

    Drugs may induce adverse drug reactions (ADRs) when they unexpectedly bind to proteins other than their therapeutic targets. Identification of these undesired protein binding partners, called off-targets, can facilitate toxicity assessment in the early stages of drug development. In this study, a computational framework was introduced for the exploration of idiosyncratic mechanisms underlying analgesic-induced severe adverse drug reactions (SADRs). The putative analgesic-target interactions were predicted by performing reverse docking of analgesics or their active metabolites against human/mammal protein structures in a high-throughput manner. Subsequently, bioinformatics analyses were undertaken to identify ADR-associated proteins (ADRAPs) and pathways. Using the pathways and ADRAPs that this analysis identified, the mechanisms of SADRs such as cardiac disorders were explored. For instance, 53 putative ADRAPs and 24 pathways were linked with cardiac disorders, of which 10 ADRAPs were confirmed by previous experiments. Moreover, it was inferred that pathways such as base excision repair, glycolysis/glyconeogenesis, ErbB signaling, calcium signaling, and phosphatidyl inositol signaling likely play pivotal roles in drug-induced cardiac disorders. In conclusion, our framework offers an opportunity to globally understand SADRs at the molecular level, which has been difficult to realize through experiments. It also provides some valuable clues for drug repurposing. - Highlights: • A novel computational framework was developed for mechanistic study of SADRs. • Off-targets of drugs were identified in large scale and in a high-throughput manner. • SADRs like cardiac disorders were systematically explored in molecular networks. • A number of ADR-associated proteins were identified.

    Complications related to the neck-stem junction of modular stems used for total hip arthroplasty (THA) are generating increasing concern. A 74-year-old male had increasing pain and a cutaneous reaction around the scar 1 year after THA with a modular neck-stem. Imaging revealed osteolysis of the calcar and a pseudo-tumour adjacent to the neck-stem junction. Serum cobalt levels were elevated. Revision surgery to exchange the stem and liner and to resect the pseudo-tumour was performed. Analysis of the stem by scanning electron microscopy and by energy dispersive X-ray and white light interferometry showed fretting corrosion at the neck-stem junction contrasting with minimal changes at the head-neck junction. Thus, despite dry assembly of the neck and stem on the back table at primary THA, full neck-stem contact was not achieved, and the resulting micromotion at the interface led to fretting corrosion. This case highlights the mechanism of fretting corrosion at the neck-stem interface responsible for adverse local tissue reactions. Clinical and radiological follow-up is mandatory in patients with dual-modular stems.

    Full Text Available AIM: To study the different clinical spectrum of cutaneous adverse drug reactions (ADR and to determine the causative drugs. MATERIALS & METHODS: A prospective, hospital based study was carried out over a period of 6 years recording various cutaneous ADR. RESULTS: A total of 500 patients with cutaneous ADR were enrolled in the study. The most common types of cutaneous ADR patterns were maculopapular rash (34.6%, fixed drug eruption (FDE (30% and urticaria (14%. The drugs most often incriminated for the various cutaneous ADR were antimicrobials (42.6%, anticonvulsants (22.2% and NSAIDs (18%. Anticonvulsants were implicated in 41.6% of maculopapular rashes. Sulfonamides accounted for 43.3% and NSAIDs for 30.7% of FDE. Urticaria was caused mainly by NSAIDs(24.3% and penicillins(20%. Anticonvulsants were responsible for 43.8% of life-threatening toxic epidermal necrolysis and Stevens Johnson syndrome. CONCLUSIONS: The clinical pattern and drugs causing cutaneous ADR are similar to those observed in other countries except for minor variations. Cutaneous ADR patterns and the drugs causing various reactions are changing every year, which may be due to the emergence of newer molecules and changing trends in the use of drugs.

    Toxic epidermal necrolysis (TEN) is an adverse reaction that can be induced by various drugs; the associated mortality rate is 20-25%. A previous report showed a weak association between TEN and acetaminophen. Recently, the US Food and Drug Administration declared that acetaminophen is associated with a risk of serious skin reactions, including TEN. Here, we describe the case of a 43-year-old Japanese woman with TEN caused by acetaminophen. She had poorly controlled ulcerative colitis and was treated with high doses of prednisolone, infliximab, acetaminophen and lansoprazole. Nine days after administrating acetaminophen, targetoid erythematous and bullous lesions appeared on the patient's trunk, palms and the soles of her feet. The skin lesions expanded rapidly; within 3 weeks, skin detachment was detected across nearly 100% of the patient's body. However, no mucosal involvement of the eyes, oral cavity or genitalia was found. We performed lymphocyte transformation tests using various drugs; however, a high stimulation index was obtained only with acetaminophen. The patient recovered following treatment with plasmapheresis, i.v. immunoglobulin therapy, topical medication and supportive therapy. Acetaminophen is included in many prescription and over-the-counter products; thus, clinicians should monitor their patients for severe drug reactions, including TEN. PMID:26362011

    Full Text Available In the era of personalized medical practice, understanding the genetic basis of patient-specific adverse drug reaction (ADR is a major challenge. Clozapine provides effective treatments for schizophrenia but its usage is limited because of life-threatening agranulocytosis. A recent high impact study showed the necessity of moving clozapine to a first line drug, thus identifying the biomarkers for drug-induced agranulocytosis has become important. Here we report a methodology termed as antithesis chemical-protein interactome (CPI, which utilizes the docking method to mimic the differences in the drug-protein interactions across a panel of human proteins. Using this method, we identified HSPA1A, a known susceptibility gene for CIA, to be the off-target of clozapine. Furthermore, the mRNA expression of HSPA1A-related genes (off-target associated systems was also found to be differentially expressed in clozapine treated leukemia cell line. Apart from identifying the CIA causal genes we identified several novel candidate genes which could be responsible for agranulocytosis. Proteins related to reactive oxygen clearance system, such as oxidoreductases and glutathione metabolite enzymes, were significantly enriched in the antithesis CPI. This methodology conducted a multi-dimensional analysis of drugs' perturbation to the biological system, investigating both the off-targets and the associated off-systems to explore the molecular basis of an adverse event or the new uses for old drugs.

Marketed Diclofenac Sodium topical formulations (A, B & C were applied on the pre-marked forearms of the subjects as per the dosing schedule. Treatment sample C was used as a reference sample. Subjects received treatment A, treatment B & treatment C on both the arms simultaneously, following open label three way parallel design. Skin Stratum Corneum samples were collected in sterile glass test tubes during the study period. The samples were collected pre-dose and at 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, & 6.0 hours post-dose application. Diclofenac Sodium was estimated in Stratum Corneum using a validated Spectroscopic method and the treatments were claimed to be bio-equivalent.The aim of this article was to report the occurrence of adverse events during this study. It was observed that only a single incidence of mild adverse event was reported in two volunteers, and it involved mild laceration on the right forearm. But, the event was found to be self resolving & with the relationship of the adverse event to study medication was “unlikely” but it could be due to the ‘tape stripping method’ employed for DPK analysis.

    The article presents a Web-based platform for collecting and storing toxicological structural alerts from literature and for virtual screening of chemical libraries to flag potentially toxic chemicals and compounds that can cause adverse side effects. An alert is uniquely identified by a SMARTS template, a toxicological endpoint, and a publication where the alert was described. Additionally, the system allows storing complementary information such as name, comments, and mechanism of action, as well as other data. Most importantly, the platform can be easily used for fast virtual screening of large chemical datasets, focused libraries, or newly designed compounds against the toxicological alerts, providing a detailed profile of the chemicals grouped by structural alerts and endpoints. Such a facility can be used for decision making regarding whether a compound should be tested experimentally, validated with available QSAR models, or eliminated from consideration altogether. The alert-based screening can also be helpful for an easier interpretation of more complex QSAR models. The system is publicly accessible and tightly integrated with the Online Chemical Modeling Environment (OCHEM, http://ochem.eu). The system is open and expandable: any registered OCHEM user can introduce new alerts, browse, edit alerts introduced by other users, and virtually screen his/her data sets against all or selected alerts. The user sets being passed through the structural alerts can be used at OCHEM for other typical tasks: exporting in a wide variety of formats, development of QSAR models, additional filtering by other criteria, etc. The database already contains almost 600 structural alerts for such endpoints as mutagenicity, carcinogenicity, skin sensitization, compounds that undergo metabolic activation, and compounds that form reactive metabolites and, thus, can cause adverse reactions. The ToxAlerts platform is accessible on the Web at http://ochem.eu/alerts, and it is constantly

  18. Systematic drug safety evaluation based on public genomic expression (Connectivity Map) data: Myocardial and infectious adverse reactions as application cases

    International Nuclear Information System (INIS)

    Adverse drug reaction (ADR) is of great importance to both regulatory agencies and the pharmaceutical industry. Various techniques, such as quantitative structure–activity relationship (QSAR) and animal toxicology, are widely used to identify potential risks during the preclinical stage of drug development. Despite these efforts, drugs with safety liabilities can still pass through safety checkpoints and enter the market. This situation raises the concern that conventional chemical structure analysis and phenotypic screening are not sufficient to avoid all clinical adverse events. Genomic expression data following in vitro drug treatments characterize drug actions and thus have become widely used in drug repositioning. In the present study, we explored prediction of ADRs based on the drug-induced gene-expression profiles from cultured human cells in the Connectivity Map (CMap) database. The results showed that drugs inducing comparable ADRs generally lead to similar CMap expression profiles. Based on such ADR-gene expression association, we established prediction models for various ADRs, including severe myocardial and infectious events. Drugs with FDA boxed warnings of safety liability were effectively identified. We therefore suggest that drug-induced gene expression change, in combination with effective computational methods, may provide a new dimension of information to facilitate systematic drug safety evaluation. - Highlights: • Drugs causing common toxicity lead to similar in vitro gene expression changes. • We built a model to predict drug toxicity with drug-specific expression profiles. • Drugs with FDA black box warnings were effectively identified by our model. • In vitro assay can detect severe toxicity in the early stage of drug development

    Currently, adverse drug reaction (ADR) causality and severity are assessed using different systems but there is no standard method to combine the results. In this work, a combined ADR causality and severity assessment system, including an online version, was developed. Logical rules were defined to translate the score obtained from the system into three alert zones: green, amber, and red. The alert zones are useful for triaging ADR cases as they help define the seriousness of the ADR and the urgency of the responses required. This new scoring system may be useful for clinicians, investigators, and regulators seeking information on the likelihood of a drug causing an adverse reaction, and whether an adverse reaction is sufficiently dangerous for the drug to be withheld or undergo further investigation.

Previous studies have been vulnerable to possible selection bias. In the study reported here, we examined the association between self-rated health and adverse events in terms of cardiac events, cardiac readmissions, and all-cause mortality in a complete cohort of patients treated with percutaneous coronary intervention (PCI.Study design and setting: A cohort of patients with coronary heart disease treated with PCI was followed up with questionnaires 4 weeks after PCI to measure self-rated health and in registers to identify adverse events. Of 1,752 eligible patients under 67 years, 26 died during the first 4 weeks. A total of 224 patients were excluded from the analysis because they were readmitted with a cardiac diagnosis before answering the first questionnaire. We received complete SF-12 Health Survey component summaries from 984 of the remaining 1,502 patients. We used multiple imputation to establish a complete cohort, including nonrespondents.Results: During follow-up, 83 patients died, 220 patients experienced a new cardiac event, and 526 patients experienced a hospital readmission related to coronary heart disease. Poor self-rated health was related to cardiac events, cardiac readmission, and all-cause mortality. The associations were stronger for all-cause mortality than for events and readmissions. Physical health was more important than mental health, but both revealed an exposure–response pattern

Suicidal ideation and preparatory behaviour were obscured in some tables owing to the lack of specificity of the medical coding dictionary......, especially COSTART. Furthermore, we found one event of suicidal ideation described in narrative text that was absent from tables and adverse event listings of individual patients. The reason for this is unclear, but may be due to the coding conventions used.

    Background In 1980, human diploid cell vaccine (HDCV, Imovax Rabies, Sanofi Pasteur), was licensed for use in the United States. Objective To assess adverse events (AEs) after HDCV reported to the US Vaccine Adverse Event Reporting System (VAERS), a spontaneous reporting surveillance system. Methods We searched VAERS for US reports after HDCV among persons vaccinated from January 1, 1990–July 31, 2015. Medical records were requested for reports classified as serious (death, hospitalization, prolonged hospitalization, disability, life-threatening-illness), and those suggesting anaphylaxis and Guillain-Barré syndrome (GBS). Physicians reviewed available information and assigned a primary clinical category to each report using MedDRA system organ classes. Empirical Bayesian (EB) data mining was used to identify disproportional AE reporting after HDCV. Results VAERS received 1,611 reports after HDCV; 93 (5.8%) were serious. Among all reports, the three most common AEs included pyrexia (18.2%), headache (17.9%), and nausea (16.5%). Among serious reports, four deaths appeared to be unrelated to vaccination. Conclusions This 25-year review of VAERS did not identify new or unexpected AEs after HDCV. The vast majority of AEs were non-serious. Injection site reactions, hypersensitivity reactions, and non-specific constitutional symptoms were most frequently reported, similar to findings in pre-licensure studies. PMID:27410239

    Full Text Available Hyaluronic acid (HA fillers in cosmetic medicine have been considered relatively safe, though fillers used in European countries and throughout the world are not necessarily approved by the Food and Drug Administration. As their use continues to expand worldwide, physicians in a wide range of medical specialties are authorized to perform HA injections, including general medicine practitioners and even dentists. An increasing number of reports have appeared regarding side effects to these products. It is now known that reactions to Hyaluronic acid are related not only to technical faults of the injections, but also to immune responses, including delayed hypersensitivity and granulomatous reactions. Herein, we describe five cases treated by a variety of treatment modalities, all with delayed reactions to different brands of hyaluronic acid fillers. As there is currently no standardization of treatment options of adverse effects, these cases accentuate the debate regarding the approach to the individual patient and the possible need for pre-testing in patients with an atopic tendency.

    Febuxostat is a new type of selective xanthine oxidase inhibitor,which mainly be used for the treatment of hyperuricemia patients with gout symptoms. The recommended initial dose of febuxostat is 40 mg once daily. In the present,there is no sufficient evidence to demonstrate that the clinical effects of febuxostat in reducing the uric acid are better than that of allopurinol. However,it is reported that febuxostat in 80 mg has better treatment effects in gout patients with diabetes or≥65 years old. The common adverse reactions of febuxostat are liver dysfunction,diarrhea,headache,nausea,rash,and so on. The differences of adverse reactions in cardiovascular system between febuxostat and allopurinol are not statistically significant.%非布司他是一种新型选择性黄嘌呤氧化酶抑制剂,主要用于具有痛风症状的高尿酸血症患者的治疗。非布司他的推荐起始剂量为40 mg,1次/d。目前尚无充分依据证实非布司他降尿酸的临床疗效优于别嘌醇,但有研究提示在合并糖尿病或年龄≥65岁的痛风患者中,非布司他80 mg/d组的治疗效果更佳。非布司他常见的不良反应包括肝功能异常、腹泻、头痛、恶心及皮疹等,心血管系统不良反应与别嘌醇比较尚未发现差异有统计学意义。

    The adverse reactions to contrast media have been investigated by several authors but the exact mechanisms have not yet been established. To study whether kinin-releasing systems are involved in these adverse reactions, we determined total plasma kininogen levels at intervals up to 30 minutes after the intravenous injections of contrast media in dogs. Injections of iohexol, iopamidol, and iothalamate decreased total plasma kininogen levels. This effect increased with increasing dose of the media and suggests that they activated the kinin-releasing systems in the plasma.

    Pharmaceutical product information (PI) supplied by the regulatory authorities serves as a source of information on safe and effective use of drugs. The objectives of this study were to qualitatively and quantitatively compare PIs for selected drugs marketed in both Denmark and the USA with respect to consistency and discrepancy of listed adverse drug reaction (ADR) information. We compared individual ADRs listed in PIs from Denmark and the USA with respect to type and frequency. Consistency was defined as match of ADRs and of ADR frequency or match could not be ruled out. Discrepancies were defined as ADRs listed only in one country or listed with different frequencies. We analyzed PIs for 40 separate drugs from ten therapeutic groups and assigned the 4003 identified ADRs to System Organ Classes (Medical Dictionary for Regulatory Activities [MedDRA] terminology). Less than half of listed ADRs (n = 1874; 47%) showed consistency. Discrepancies (n = 2129; 53%) were split into ADRs listed only in the USA (n = 1558; 39%), ADRs listed only in Denmark (n = 325; 8%) and ADRs listed with different frequencies (n = 246; 6%). The majority of listed ADRs were of the type "gastrointestinal disorders" and "nervous system disorders". Our results show great differences in PIs for drugs approved in both Denmark and the USA illuminating concerns about the credibility of the publicly available PIs. The results also represent an argument for further harmonization across borders to improve consistency between authority-supplied information. PMID:25505588

    The aim of the present study was to undertake a study on the prevalence of cytochrome P450 2D6 (CYP2D6) poor metabolizer alleles (*3, *4, *5, and *6) on a Montenegrin population and its impact on developing adverse drug reactions (ADRs) of β-blockers in a hospitalized cardiac patient population. A prospective study was conducted in the Cardiology Center of the Clinical Center of Montenegro and included 138 patients who had received any β-blocker in their therapy. ADRs were collected using a specially designed questionnaire, based on the symptom list and any signs that could point to eventual ADRs. Data from patients’ medical charts, laboratory tests, and other available parameters were observed and combined with the data from the questionnaire. ADRs to β-blockers were observed in 15 (10.9%) patients. There was a statistically significant difference in the frequency of ADRs in relation to genetically determined enzymatic activity (Phospitalization, CYP2D6 poor metabolizer phenotype, and the concomitant use of other CYP2D6-metabolizing drugs. Therefore, in hospitalized patients with polypharmacy CYP2D6 genotyping might be useful in detecting those at risk of ADRs.

    2006-04-01

    Full Text Available Abstract Background Computed Tomography Cholangiography (CTC is a fast and widely available alternative technique to visualise hepatobiliary disease in patients with an inconclusive ultrasound when MRI cannot be performed. The method has previously been relatively unknown and sparsely used, due to concerns about adverse reactions and about image quality in patients with impaired hepatic function and thus reduced contrast excretion. In this retrospective study, the feasibility and the frequency of adverse reactions of CTC when using a drip infusion scheme based on bilirubin levels were evaluated. Methods The medical records of patients who had undergone upper abdominal spiral CT with subsequent three-dimensional rendering of the biliary tract by means of CTC during seven years were retrospectively reviewed regarding serum bilirubin concentration, adverse reaction and presence of visible contrast media in the bile ducts at CT examination. In total, 153 consecutive examinations in 142 patients were reviewed. Results Contrast media was observed in the bile ducts at 144 examinations. In 110 examinations, the infusion time had been recorded in the medical records. Among these, 42 examinations had an elevated bilirubin value (>19 umol/L. There were nine patients without contrast excretion; 3 of which had a normal bilirubin value and 6 had an elevated value (25–133 umol/L. Two of the 153 examinations were inconclusive. One subject (0.7% experienced a minor adverse reaction – a pricking sensation in the face. No other adverse effects were noted. Conclusion We conclude that drip infusion CTC with an infusion rate of the biliary contrast agent iotroxate governed by the serum bilirubin value is a feasible and safe alternative to MRC in patients with and without impaired biliary excretion. In this retrospective study the feasibility and the frequency of adverse reactions when using a drip infusion scheme based on bilirubin levels has been evaluated.

The World Health Organization, through its Patient Safety Programme, adopted as a priority the objective to facilitate and stimulate global learning through enhanced reporting of patient safety incidents. Landmark developments were the WHO Draft Guidelines for Adverse Event Reporting and Learning Systems, and the Conceptual Framework for the International Classification for Patient Safety, as well as the Global Community of Practice for Reporting and Learning Systems. WHO is currently working with a range of scientists, medical informatics specialists and healthcare officials from various countries around the world, to arrive at a Minimal Information Model that could serve as a basis to structure the core of reporting systems in a comparable manner across the world. Undoubtedly, there is much need for additional scientific developments in this challenging and innovative area. For effective reporting systems and enhanced global learning, other key contextual factors are essential for reporting to serve to the needs of clinicians, patients and the healthcare system at large. Moreover, the new data challenges and needs of organizations must be assessed as the era of big data comes to heath care. These considerations delineate a broad agenda for action, which offer an ambitious challenge for WHO and their partners interested in strengthening learning for improving through reporting and communicating about patient safety incidents.

    Background Little is known about how adverse events are summarised and reported in trials, as detailed information is usually considered confidential. We have acquired clinical study reports (CSRs) from the European Medicines Agency through the Freedom of Information Act. The CSRs describe the results of studies conducted as part of the application for marketing authorisation for the slimming pill orlistat. The purpose of this study was to study how adverse events were summarised and reported in study protocols, CSRs, and published papers of orlistat trials. Methods and Findings We received the CSRs from seven randomised placebo controlled orlistat trials (4,225 participants) submitted by Roche. The CSRs consisted of 8,716 pages and included protocols. Two researchers independently extracted data on adverse events from protocols and CSRs. Corresponding published papers were identified on PubMed and adverse event data were extracted from this source as well. All three sources were compared. Individual adverse events from one trial were summed and compared to the totals in the summary report. None of the protocols or CSRs contained instructions for investigators on how to question participants about adverse events. In CSRs, gastrointestinal adverse events were only coded if the participant reported that they were “bothersome,” a condition that was not specified in the protocol for two of the trials. Serious adverse events were assessed for relationship to the drug by the sponsor, and all adverse events were coded by the sponsor using a glossary that could be updated by the sponsor. The criteria for withdrawal due to adverse events were in one case related to efficacy (high fasting glucose led to withdrawal), which meant that one trial had more withdrawals due to adverse events in the placebo group. Finally, only between 3% and 33% of the total number of investigator-reported adverse events from the trials were reported in the publications because of post hoc

    Full Text Available While yoga is gaining increased popularity in North America and Europe, its safety has been questioned in the lay press. The aim of this systematic review was to assess published case reports and case series on adverse events associated with yoga. Medline/Pubmed, Scopus, CAMBase, IndMed and the Cases Database were screened through February 2013; and 35 case reports and 2 case series reporting a total of 76 cases were included. Ten cases had medical preconditions, mainly glaucoma and osteopenia. Pranayama, hatha yoga, and Bikram yoga were the most common yoga practices; headstand, shoulder stand, lotus position, and forceful breathing were the most common yoga postures and breathing techniques cited. Twenty-seven adverse events (35.5% affected the musculoskeletal system; 14 (18.4% the nervous system; and 9 (11.8% the eyes. Fifteen cases (19.7% reached full recovery; 9 cases (11.3% partial recovery; 1 case (1.3% no recovery; and 1 case (1.3% died. As any other physical or mental practice, yoga should be practiced carefully under the guidance of a qualified instructor. Beginners should avoid extreme practices such as headstand, lotus position and forceful breathing. Individuals with medical preconditions should work with their physician and yoga teacher to appropriately adapt postures; patients with glaucoma should avoid inversions and patients with compromised bone should avoid forceful yoga practices.

    Full Text Available PURPOSE: Adverse drug events (ADEs are common and often preventable among inpatients, but self-reported ADEs have not been investigated in a representative sample of the general public. The objectives of this study were to estimate the 1-month prevalence of self-reported ADEs among the adult general public, and the perceived preventability of 2 ADE categories: adverse drug reactions (ADRs and sub-therapeutic effects (STEs. METHODS: In this cross-sectional study, a postal survey was sent in October 2010 to a random sample of 13 931 Swedish residents aged ≥ 18 years. Self-reported ADEs experienced during the past month included ADRs, STEs, drug dependence, drug intoxications and morbidity due to drug-related untreated indication. ADEs could be associated with prescription, non-prescription or herbal drugs. The respondents estimated whether ADRs and STEs could have been prevented. ADE prevalences in age groups (18-44, 45-64, or ≥65 years were compared. RESULTS: Of 7099 respondents (response rate 51.0%, ADEs were reported by 19.4% (95% confidence interval, 18.5-20.3%, and the prevalence did not differ by age group (p>0.05. The prevalences of self-reported ADRs, STEs, and morbidities due to drug-related untreated indications were 7.8% (7.2-8.4%, 7.6% (7.0-8.2% and 8.1% (7.5-8.7%, respectively. The prevalence of self-reported drug dependence was 2.2% (1.9-2.6%, and drug intoxications 0.2% (0.1-0.3%. The respondents considered 19.2% (14.8-23.6% of ADRs and STEs preventable. Although reported drugs varied between ADE categories, most ADEs were attributable to commonly dispensed drugs. Drugs reported for all and preventable events were similar. CONCLUSIONS: One-fifth of the adult general public across age groups reported ADEs during the past month, indicating a need for prevention strategies beyond hospitalised patients. For this, the underlying causes of ADEs should increasingly be investigated. The high burden of ADEs and preventable ADEs from

    In April 2010, President Obama declared a space pioneering goal for the United States in general and NASA in particular. "Fifty years after the creation of NASA, our goal is no longer just a destination to reach. Our goal is the capacity for people to work and learn and operate and live safely beyond the Earth for extended periods of time, ultimately in ways that are more sustainable and even indefinite." Thus NASA's Strategic Objective 1.1 emerged as "expand human presence into the solar system and to the surface of Mars to advance exploration, science, innovation, benefits to humanity, and international collaboration" (NASA 2015b). Any space flight, be it of long or short duration, occurs in an extreme environment that has unique stressors. Even with excellent selection methods, the potential for behavioral problems among space flight crews remain a threat to mission success. Assessment of factors that are related to behavioral health can help minimize the chances of distress and, thus, reduce the likelihood of adverse cognitive or behavioral conditions and psychiatric disorders arising within a crew. Similarly, countermeasures that focus on prevention and treatment can mitigate the cognitive or behavioral conditions that, should they arise, would impact mission success. Given the general consensus that longer duration, isolation, and confined missions have a greater risk for behavioral health ensuring crew behavioral health over the long term is essential. Risk, which within the context of this report is assessed with respect to behavioral health and performance, is addressed to deter development of cognitive and behavioral degradations or psychiatric conditions in space flight and analog populations, and to monitor, detect, and treat early risk factors, predictors and other contributing factors. Based on space flight and analog evidence, the average incidence rate of an adverse behavioral health event occurring during a space mission is relatively low for the

    AIMS: Physical activity is protective against cardiovascular (CV) events, both in general population and in high-risk CV cohorts. However, the relationship between physical activity with major adverse outcomes in atrial fibrillation (AF) is not well-established. Our aim was to analyse...... this relationship in a 'real-world' AF population. Second, we investigated the influence of physical activity on arrhythmia progression. METHODS AND RESULTS: We studied all patients enrolled in the EURObservational Research Programme on AF (EORP-AF) Pilot Survey. Physical activity was defined as 'none', 'occasional......', 'regular', and 'intense', based on patient self-reporting. Data on physical activity were available for 2442 patients: 38.9% reported none, 34.7% occasional, 21.7% regular, and 4.7% intense physical activity. Prevalence of the principal CV risk factors progressively decreased from none to intense physical...

  7. Haplotype-Based Analysis of Genes Associated With Risk of Adverse Skin Reactions After Radiotherapy in Breast Cancer Patients

    International Nuclear Information System (INIS)

    Purpose: To identify haplotypes of single nucleotide polymorphism markers associated with the risk of early adverse skin reactions (EASRs) after radiotherapy in breast cancer patients. Methods and Materials: DNA was sampled from 399 Japanese breast cancer patients who qualified for breast-conserving radiotherapy. Using the National Cancer Institute-Common Toxicity Criteria scoring system, version 2, the patients were grouped according to EASRs, defined as those occurring within 3 months of starting radiotherapy (Grade 1 or less, n = 290; Grade 2 or greater, n = 109). A total of 999 single nucleotide polymorphisms from 137 candidate genes for radiation susceptibility were genotyped, and the haplotype associations between groups were assessed. Results: The global haplotype association analysis (p < 0.05 and false discovery rate < 0.05) indicated that estimated haplotypes in six loci were associated with EASR risk. A comparison of the risk haplotype with the most frequent haplotype in each locus showed haplotype GGTT in CD44 (odds ratio [OR] = 2.17; 95% confidence interval [CI], 1.07-4.43) resulted in a significantly greater EASR risk. Five haplotypes, CG in MAD2L2 (OR = 0.55; 95% CI, 0.35-0.87), GTTG in PTTG1 (OR = 0.48; 95% CI, 0.24-0.96), TCC (OR = 0.48; 95% CI, 0.26-0.89) and CCG (OR = 0.50; 95% CI, 0.27-0.92) in RAD9A, and GCT in LIG3 (OR = 0.46; 95% CI, 0.22-0.93) were associated with a reduced EASR risk. No significant risk haplotype was observed in REV3L. Conclusion: Individual radiosensitivity can be partly determined by these haplotypes in multiple loci. Our findings may lead to a better understanding of the mechanisms underlying the genetic variation in radiation sensitivity and resistance among breast cancer patients

    AIM: The study was to screen the possible risk factors of adverse drug reaction (ADR) induced by non-steroidal anti-inflammatory drugs (NSAIDs) in Shanghai patients with arthropathy. METHODS: The subjects were randomly selected from a database of outpatients with arthropathy from 9 main hospitals in Shanghai. A door to door retrospective epidemiological survey was used to collect demographic information about the patients, both individual and familial. This included data on their medical histories, lifestyle and dietary habits, history of smoking and alcohol consumption, history of drug therapy, quality of life (QOL) prior to NSAIDs intake, history of NSAIDs therapy and its ADR events, etc. Descriptive statistical methods and univariate analysis were also used to identify possible risk factors for ADRs induced by NSAIDs. RESULTS: Of the 1002 patients surveyed, the average length of NSAIDs intake was 2 years. ADR incidence from different NSAIDs was high, in a range from 46.7 %-66.2 %.In general, the candidate risk factors for ADRs were different for each NSAID. Each of the candidate risk factors were defined and studied in order to evaluate its role in the determination of ADRs from NSAIDs. "Family history of ADRs caused by NSAIDs" was found to be a significant risk factor for the four commonly used NSAIDs:meloxicam, diclofenac, nimesulide, and nabumetone. CONCLUSION: A retrospective epidemiological survey was useful in detecting the risk factors for ADRs caused by NSAIDs. The study found that different NSAIDs might have different risk factors and that there is no single risk factor universally applicable to all NSAIDs.

    Full Text Available User-generated medical messages on Internet contain extensive information related to adverse drug reactions (ADRs and are known as valuable resources for post-marketing drug surveillance. The aim of this study was to find an effective method to identify messages related to ADRs automatically from online user reviews.We conducted experiments on online user reviews using different feature set and different classification technique. Firstly, the messages from three communities, allergy community, schizophrenia community and pain management community, were collected, the 3000 messages were annotated. Secondly, the N-gram-based features set and medical domain-specific features set were generated. Thirdly, three classification techniques, SVM, C4.5 and Naïve Bayes, were used to perform classification tasks separately. Finally, we evaluated the performance of different method using different feature set and different classification technique by comparing the metrics including accuracy and F-measure.In terms of accuracy, the accuracy of SVM classifier was higher than 0.8, the accuracy of C4.5 classifier or Naïve Bayes classifier was lower than 0.8; meanwhile, the combination feature sets including n-gram-based feature set and domain-specific feature set consistently outperformed single feature set. In terms of F-measure, the highest F-measure is 0.895 which was achieved by using combination feature sets and a SVM classifier. In all, we can get the best classification performance by using combination feature sets and SVM classifier.By using combination feature sets and SVM classifier, we can get an effective method to identify messages related to ADRs automatically from online user reviews.

    Although drug therapy is inherently associated with the risk of adverse drug reactions (ADRs), some of these events are preventable. The estimated proportion of preventable ADRs varies from one study or clinical context to another. Bleeding caused by antithrombotic agents (and particularly vitamin K antagonists, VKAs) constitutes one of the most frequent causes of ADR-related hospitalization.Hence, the objective of the present study was to adapt and validate an ADR preventability score for bleeding due to VKAs and evaluate the preventability of bleeding in 906 consecutive hospitalized, VKA-treated adult patients with a risk of major bleeding (defined as an international normalized ratio ≥5) over a 2-year period. A specific preventability scale for VKA-associated bleeding was developed by adapting a published tool.Overall, 241 of the 906 patients in the study experienced at least 1 VKA-associated bleeding event. The scale's reliability was tested by 2 different evaluators. The inter-rater reliability (evaluated by calculation of Cohen's kappa) ranged from "good" to "excellent." Lastly, the validated scale was used to assess the preventability of the VKA-associated bleeding. We estimated that bleeding was preventable or potentially preventable in 109 of the 241 affected patients (45.2%).We have developed a useful, reliable tool for evaluating the preventability of VKA-associated bleeding. Application of the scale in a prospective study revealed that a high proportion of VKA-associated bleeding events in hospitalized, at-risk adult patients were preventable or potentially preventable.

    2012-01-31

    The study of errors in medicine has proliferated since the publication of The Institute of Medicine Report \\'TO ERR IS HUMAN\\' in 2000. Case nuances and process of care issues are valuable areas to explore if the goal is to provide the health care worker with the knowledge to avoid future errors. Meta-analysis and randomized controlled trials provide a large data base of evidence towards improvement and opportunities, but it is suggested that case reports can still provide valuable clinical information. The aim is to use the published literature to produce a series of rare harm case reports in E.N.T. The methods include systematic literature review. Journals searched in PUBMED were 60. Rare harm case obtained from the search were 5,322. Rare harm case reports not reported in any other form of evidence-based medicine were 40. Yes, the case report can be defended as it is an important pillar of evidence-based medicine.

    Objective To clarify the definition and scope of "adverse drug reaction surveillance". Methods The etymology, usages, and previous definitions of 'surveillance' were examined. The history and practice of adverse drug reaction surveillance was reviewed and a distinction among the concept framework of "adverse drug reaction surveillance","pharmacovigilance" and"pharmacoepidemiology" was made. Results The targets of surveillance are harmful potentially; "ongoing","systematic", "collection", "analysis", "interpretation", and "dissemination" have been seen in any surveillance program. Surveillance starts as soon as the drug is first approved or at any time thereafter. The collected data involves not only the safety problems caused by the nature of the drug, but also related to drug standards, pharmaceutical production, drug storage and drug usages. Information technology has greatly promoted the surveillance. Conclusion Definition of adverse drug reaction surveillance is proposed: A public health program aimed to adverse drug reactions, consisting of a set of processes for the ongoing systematic collection, compilation, analysis, interpretation of drug safety data(including relevant spontaneous reports, electronic health records, and experimental data), closely integrated with the timely and coherent dissemination of the results and assessment to those (including regulators, healthcare professionals and public) who have the right to know so that action can be taken. The purpose is to learn the distribution and trend of drug safety, to identify, evaluate, understand, and communicate the unexpected adverse drug effects, to perfect the drug benefit -risk profile, in order to prevent or mitigate the harmful effects of drugs.%目的:明确“药品不良反应监测”的定义及范畴,厘清药品不良反应监测的概念。方法回顾“监测”的语源学,以及作为术语在疾病监测或公共卫生监测中的定义和范畴;回顾药品不良反应

Japan Chiebukuro”. Our aim was to clarify the characteristics related to people’s descriptions of suspected ADRs and determine the reasons for submitting a spontaneous inquiry. Methods: Fifty brand names of medicines used for inquiry extraction were chosen by selecting 35 pharmaceutical products, based on the generic names that had the highest sales in Japan. Questions containing both the brand name of one of these medicines and the term “Fukusayō” (ADR in Japanese that were posted from July 2004 to June 2009 were extracted from the site. Results: Among 1,419 questions extracted, 614 questions had at least one identifiable brand name of a suspected medicine, an ADR description, and the extent to which the ADR appeared to be caused by the suspected medicine(s. Among these 614 questions, 589 described in detail the symptoms/signs that the inquirers themselves or their families had experienced as ADRs. The highest number of questions was found for Paxil (525. Posts asking whether the symptoms being experienced were due to an ADR accounted for the highest number of questions. In most cases, the inquirer suspected that a single medicine led to an ADR and was seeking advice from others taking the same medicine. Conclusion: Our examination of spontaneous inquiries showed that people have sufficient knowledge to adequately report potential ADRs in terms of their symptoms

    Full Text Available Objectives: Toxicity of cancer chemotherapy may be affected by nutritional status of patients which is reflected in the body mass index (BMI. We sought to assess whether the adverse drug reaction (ADR profile of platinum-based chemotherapy varies with BMI status. Materials and Methods: Adult patients of either sex, suffering from a solid tumor (lung, head and neck, ovary, gall bladder, stomach, colon and started on platinum-based chemotherapy as initial treatment were included. BMI at chemotherapy commencement was obtained from medical records. Events were recorded and graded as per Eastern Co-operative Oncology Group Common Toxicity Criteria-patients′ complaints; clinically evident signs and laboratory reports were considered. Frequencies of individual adverse events were compared between low BMI (<18.5 kg/m 2 and satisfactory BMI groups. Similar comparisons were done for events with grades 2 or 3 severities. Results: A total of 50 patients were observed over a 3-month period of whom 17 (34% belonged to the low BMI group. Nausea, vomiting, diarrhea, stomatitis, anemia, alopecia, tinnitus and paresthesia were the commonly observed ADRs. The frequencies of anemia (P = 0.152 and vomiting (P = 0.140 and severity of grades of nausea (P = 0.066, anemia (P = 0.120 and paresthesia (P = 0.128 showed a higher trend in the low BMI group though differences were not statistically significant. The frequencies of tinnitus (P = 0.021 and paresthesia overall (P = 0.036 were significantly higher in the low BMI group. Conclusion: ADR profile of primary platinum-based chemotherapy appears to be partly influenced by BMI. This suggests the importance of maintaining adequate nutrition in patients and the need for greater vigilance in those with low BMI.

    Full Text Available Although voriconazole, a triazole antifungal, is a safe drug, treatment with this agent is associated with certain adverse events such as hepatic, neurologic, and visual disturbances. The current report presents two cases, one a 9-year-old boy and the other a 17-year-old girl, who experienced neurologic side effects associated with voriconazole therapy. Our aim is to remind readers of the side effects of voriconazole therapy in order to prevent unnecessary investigations especially for psychological and ophthalmologic problems. The first case was a 9-year-old boy with cystic fibrosis and invasive aspergillosis that developed photophobia, altered color sensation, and fearful visual hallucination. The second case was a 17-year-old girl with cystic fibrosis and allergic bronchopulmonary aspergillosis, and she experienced photophobia, fatigue, impaired concentration, and insomnia, when the dose of voriconazole therapy was increased from 12 mg/kg/day to 16 mg/kg/day. The complaints of the two patients disappeared after discontinuation of voriconazole therapy. Our experience in these patients reminded us of the importance of being aware of the neurologic adverse events associated with voriconazole therapy in establishing early diagnosis and initiating prompt treatment. In addition, although serum voriconazole concentration was not measured in the present cases, therapeutic drug monitoring for voriconazole seems to be critically important in preventing neurologic side effects in pediatric patients.

    Full Text Available Consistent with cognitive views of depression, we aimed to investigate the mediating role of personal goals in the relationship between stressful events and distinct patterns of depressive symptoms in a nonclinical sample. Participants identified a dysphoric episode that occurred in the previous year by reporting the severity of 12 depressive symptoms and their plausible cause. A goal taxonomy was used to determine how much the event interfered with the achievement of a series of personal goals. After controlling for age and current level of depression, the patterns of symptoms differed based on the triggering events. The relationship between sadness and affective losses was partially mediated by the personal goal of lovableness, and success was a partial mediator in the association between an event of failure and symptoms of worthlessness and anhedonia. Although the cross-sectional design of the study does not allow for conclusions on the direction of effects, findings suggest the importance of motivational factors in the development of specific patterns of depressive symptoms to adverse events. Assuming a continuum from low mood to clinical depression, treatment models could benefit from a precise identification of the specific stressors that initiate depressive behaviour and the personal meaning assigned to those events.

    Full Text Available Background. Ewing sarcoma family of tumors (ESFT are rare but deadly cancers of unknown etiology. Few risk factors have been identified. This study was undertaken to ascertain any possible association between exposure to therapeutic drugs and ESFT. Methods. This is a retrospective, descriptive study. A query of the FDA Adverse Event Reporting System (FAERS was conducted for all reports of ESFT, January 1, 1998, through December 31, 2013. Report narratives were individually reviewed for patient characteristics, underlying conditions and drug exposures. Results. Over 16 years, 134 ESFT reports were identified, including 25 cases of ESFT following therapeutic drugs and biologics including immunosuppressive agents and hormones. Many cases were confounded by concomitant medications and other therapies. Conclusions. This study provides a closer look at medication use and underlying disorders in patients who later developed ESFT. While this study was not designed to demonstrate any clear causative association between ESFT and prior use of a single product or drug class, many drugs were used to treat immune-related disease and growth or hormonal disturbances. Further studies may be warranted to better understand possible immune or neuroendocrine abnormalities or exposure to specific classes of drugs that may predispose to the later development of ESFT.

    This final rule revises existing regulations under sections 401 through 432 of the Health Care Quality Improvement Act of 1986, governing the National Practitioner Data Bank for Adverse Information on Physicians and Other Health Care Practitioners, to incorporate statutory requirements under section 1921 of the Social Security Act, as amended by section 5(b) of the Medicare and Medicaid Patient and Program Protection Act of 1987 (MMPPPA), and as amended by the Omnibus Budget Reconciliation Act of 1990 (OBRA). The MMPPPA, along with certain additional provisions in the OBRA, was designed to protect program beneficiaries from unfit health care practitioners, and otherwise improve the anti-fraud provisions of Medicare and State health care programs. Section 1921, the statutory authority upon which this regulatory action is based, requires each State to adopt a system of reporting to the Secretary of Health and Human Services (the Secretary) certain adverse licensure actions taken against health care practitioners and health care entities licensed or otherwise authorized by a State (or a political subdivision thereof) to provide health care services. It also requires each State to report any negative actions or findings that a State licensing authority, peer review organization, or private accreditation entity has concluded against a health care practitioner or health care entity.

  11. Low-dose adrenaline, promethazine, and hydrocortisone in the prevention of acute adverse reactions to antivenom following snakebite: a randomised, double-blind, placebo-controlled trial.

    H Asita de Silva

    2011-05-01

    Full Text Available BACKGROUND: Envenoming from snakebites is most effectively treated by antivenom. However, the antivenom available in South Asian countries commonly causes acute allergic reactions, anaphylactic reactions being particularly serious. We investigated whether adrenaline, promethazine, and hydrocortisone prevent such reactions in secondary referral hospitals in Sri Lanka by conducting a randomised, double-blind placebo-controlled trial. METHODS AND FINDINGS: In total, 1,007 patients were randomized, using a 2 × 2 × 2 factorial design, in a double-blind, placebo-controlled trial of adrenaline (0.25 ml of a 1∶1,000 solution subcutaneously, promethazine (25 mg intravenously, and hydrocortisone (200 mg intravenously, each alone and in all possible combinations. The interventions, or matching placebo, were given immediately before infusion of antivenom. Patients were monitored for mild, moderate, or severe adverse reactions for at least 96 h. The prespecified primary end point was the effect of the interventions on the incidence of severe reactions up to and including 48 h after antivenom administration. In total, 752 (75% patients had acute reactions to antivenom: 9% mild, 48% moderate, and 43% severe; 89% of the reactions occurred within 1 h; and 40% of all patients were given rescue medication (adrenaline, promethazine, and hydrocortisone during the first hour. Compared with placebo, adrenaline significantly reduced severe reactions to antivenom by 43% (95% CI 25-67 at 1 h and by 38% (95% CI 26-49 up to and including 48 h after antivenom administration; hydrocortisone and promethazine did not. Adding hydrocortisone negated the benefit of adrenaline. CONCLUSIONS: Pretreatment with low-dose adrenaline was safe and reduced the risk of acute severe reactions to snake antivenom. This may be of particular importance in countries where adverse reactions to antivenom are common, although the need to improve the quality of available antivenom cannot be

    Full Text Available BACKGROUND: In recent years, efforts have been made to improve paediatric drug therapy. The aim of this research was to investigate any changes regarding the frequency and nature of adverse drug reactions (ADRs in hospitalized children in one paediatric general medical ward over a 9-year period. METHODOLOGY: Two prospective observational cohort studies were conducted at a large University hospital in Germany in 1999 and 2008, respectively. Children aged 0-18 years admitted to the study ward during the study periods were included. ADRs were identified using intensive chart review. Uni- and multivariable regression has been used for data analysis. RESULTS: A total of 520 patients (574 admissions were included [1999: n = 144 (167; 2008: n = 376 (407]. Patients received a total of 2053 drugs [median 3, interquartile range (IQR 2-5]. 19% of patients did not receive any medication. Median length of stay was 4 days (IQR 3-7; range 1-190 days with a significantly longer length of stay in 1999. The overall ADR incidence was 13.1% (95% CI, 9.8-16.3 varying significantly between the two study cohorts [1999: 21.9%, 95% CI, 14.7-29.0; 2008: 9.2%, 95% CI, 5.9-12.5 (p<0.001]. Antibacterials and corticosteroids for systemic use caused most of the ADRs in both cohorts (1999; 2008. Exposure to systemic antibacterials decreased from 62.9% to 43.5% whereas exposure to analgesics and anti-inflammatory drugs increased from 17.4% to 45.2%, respectively. The use of high risk drugs decreased from 75% to 62.2%. In 1999, 45.7% and in 2008 96.2% of ADRs were identified by treating clinicians (p<0.001. CONCLUSIONS: Between 1999 and 2008, the incidence of ADRs decreased significantly. Improved treatment strategies and an increased awareness of ADRs by physicians are most likely to be the cause for this positive development. Nevertheless further research on ADRs particularly in primary care and the establishment of prospective pharmacovigilance systems are still

    Limited data exist on the burden of serious adverse drug reactions (ADRs) in sub-Saharan Africa, which has high HIV and tuberculosis prevalence. We determined the proportion of adult admissions attributable to ADRs at 4 hospitals in South Africa. We characterized drugs implicated in, risk factors for, and the preventability of ADR-related admissions.We prospectively followed patients admitted to 4 hospitals' medical wards over sequential 30-day periods in 2013 and identified suspected ADRs with the aid of a trigger tool. A multidisciplinary team performed causality, preventability, and severity assessment using published criteria. We categorized an admission as ADR-related if the ADR was the primary reason for admission.There were 1951 admissions involving 1904 patients: median age was 50 years (interquartile range 34-65), 1057 of 1904 (56%) were female, 559 of 1904 (29%) were HIV-infected, and 183 of 1904 (10%) were on antituberculosis therapy (ATT). There were 164 of 1951 (8.4%) ADR-related admissions. After adjustment for age and ATT, ADR-related admission was independently associated (P ≤ 0.02) with female sex (adjusted odds ratio [aOR] 1.51, 95% confidence interval [95% CI] 1.06-2.14), increasing drug count (aOR 1.14 per additional drug, 95% CI 1.09-1.20), increasing comorbidity score (aOR 1.23 per additional point, 95% CI 1.07-1.41), and use of antiretroviral therapy (ART) if HIV-infected (aOR 1.92 compared with HIV-negative/unknown, 95% CI 1.17-3.14). The most common ADRs were renal impairment, hypoglycemia, liver injury, and hemorrhage. Tenofovir disoproxil fumarate, insulin, rifampicin, and warfarin were most commonly implicated, respectively, in these 4 ADRs. ART, ATT, and/or co-trimoxazole were implicated in 56 of 164 (34%) ADR-related admissions. Seventy-three of 164 (45%) ADRs were assessed as preventable.In our survey, approximately 1 in 12 admissions was because of an ADR. The range of ADRs and implicated drugs reflect South Africa's high HIV

    Full Text Available Background: Polypharmacy, advancing age and longer duration of hospital stay are the factors responsible for adverse drug reactions (ADRs. This study has attempted to analyze the pattern of antimicrobial prescription in OPD & IPD of the Otolaryngology department and to detect, document, assess and report the suspected ADRs due to antibiotic use and preparation of guidelines to minimize the incidence of ADRs. Methods: A prospective study conducted at the TMMC&RC on patients aged >40 years, who visited the Otolaryngology department over a period of 5 months. Suspected ADRs were assessed for causality and severity using Naranjo’s probability scale and modified Hartwig’s criteria, respectively. Results: Out of 1200, 925 prescriptions were analyzed. Most patients were from 41-60 age (59.45% followed by 61-80 age (37.29% and least from >80 yr (3.24%. But the incidence of ADRs were found to be higher in patients of >80 yr age group n=8 (26.66%. The most commonly prescribed antibacterials were β-Lactams (64.61%. Out of 925 prescriptions studied, only 94 were found to have 154 ADRs. The most commonly identified ADRs were Gastrointestinal 47.40%, followed by Neurotoxicity 24.67%, cutaneous reactions 20.12%, Hepatic 4.54% and Kidney 3.24%. 74.67% of the ADRs were probable and 20.77% were possible type and only 4.54% were definite. 74.67% ADRs were found to be type A, and 25.32% type B. Conclusions: Our study showed that prevalence of ADRs was highest in elder age group and diarrhea was the most common ADR found. Therefore elderly patients should be given special attention when prescribing medications to avoid clinically significant harmful consequences. Minimizing unnecessary antibiotic use by even a small percentage could significantly reduce the immediate and direct risks of drug-related adverse events in individual patients.

    2011-02-01

    Full Text Available Abstract Background Patient record review is believed to be the most useful method for estimating the rate of adverse events among hospitalised patients. However, the method has some practical and financial disadvantages. Some of these disadvantages might be overcome by using existing reporting systems in which patient safety issues are already reported, such as incidents reported by healthcare professionals and complaints and medico-legal claims filled by patients or their relatives. The aim of the study is to examine to what extent the hospital reporting systems cover the adverse events identified by patient record review. Methods We conducted a retrospective study using a database from a record review study of 5375 patient records in 14 hospitals in the Netherlands. Trained nurses and physicians using a method based on the protocol of The Harvard Medical Practice Study previously reviewed the records. Four reporting systems were linked with the database of reviewed records: 1 informal and 2 formal complaints by patients/relatives, 3 medico-legal claims by patients/relatives and 4 incident reports by healthcare professionals. For each adverse event identified in patient records the equivalent was sought in these reporting systems by comparing dates and descriptions of the events. The study focussed on the number of adverse event matches, overlap of adverse events detected by different sources, preventability and severity of consequences of reported and non-reported events and sensitivity and specificity of reports. Results In the sample of 5375 patient records, 498 adverse events were identified. Only 18 of the 498 (3.6% adverse events identified by record review were found in one or more of the four reporting systems. There was some overlap: one adverse event had an equivalent in both a complaint and incident report and in three cases a patient/relative used two or three systems to complain about an adverse event.

    Despite the importance of reporting systems to learn about the casual chain and consequences of patient safety incidents, this is an area that requires of further conceptual and technical developments to conduce reporting to effective learning. The World Health Organization, through its Patient Safety Programme, adopted as a priority the objective to facilitate and stimulate global learning through enhanced reporting of patient safety incidents. Landmark developments were the WHO Draft Guidelines for Adverse Event Reporting and Learning Systems, and the Conceptual Framework for the International Classification for Patient Safety, as well as the Global Community of Practice for Reporting and Learning Systems. WHO is currently working with a range of scientists, medical informatics specialists and healthcare officials from various countries around the world, to arrive at a Minimal Information Model that could serve as a basis to structure the core of reporting systems in a comparable manner across the world. Undoubtedly, there is much need for additional scientific developments in this challenging and innovative area. For effective reporting systems and enhanced global learning, other key contextual factors are essential for reporting to serve to the needs of clinicians, patients and the healthcare system at large. Moreover, the new data challenges and needs of organizations must be assessed as the era of big data comes to heath care. These considerations delineate a broad agenda for action, which offer an ambitious challenge for WHO and their partners interested in strengthening learning for improving through reporting and communicating about patient safety incidents. Significance for public healthUnderstanding the causes and consequences of incidents is cornerstone for patient safety improvement. Likewise, setting up systems to facilitate such understanding and communicate the learning across all healthcare actors is crucial. Over the past decade, the World Health

    Itoh, Kenji; Andersen, Henning Boje; Madsen, Marlene Dyrløv; Østergaard, Doris; Ikeno, Masaaki

    2006-07-01

    In the present paper, we report results of surveys in 2003 in Japan and Denmark about patients' views about adverse events, focusing on the actions of healthcare staff involved in a medical accident. Results show that patients were more likely to indicate negative expectations to a doctor's reactions after a medical accident when asked in general terms than when asked in relation to concrete case stories. When asked in general terms, 66% (47%) of Japanese (Danish) respondents expected that doctors sometimes hold back on providing information to patients about a medical accident, while 37% (7%) did so when asked about a concrete, mild-outcome case. We examine some possible reasons for the relatively high level of distrust of Japanese patients, and we discuss whether the seemingly lower level of disclosure in Japan than in Denmark and the negative stories in the Japanese press may have an impact. We also suggest some implications for introducing a patient-centred or customer-centred approach to risk management in healthcare and other domains. PMID:16759631

    Full Text Available Abstract Background Consumption of alcohol is associated with acute and chronic adverse health outcomes. There is a paucity of studies that explore the determinants of alcohol use among adolescents in sub-Saharan Africa and, in particular, that examine the effects of adverse childhood experiences on alcohol use. Methods The paper draws on nationally-representative data from 9,819 adolescents aged 12-19 years from Burkina Faso, Ghana, Malawi, and Uganda. Logistic regression models were employed to identify correlates of self-reported past-year drunkenness. Exposure to four adverse childhood experiences comprised the primary independent variables: living in a food-insecure household, living with a problem drinker, having been physically abused, and having been coerced into having sex. We controlled for age, religiosity, current schooling status, the household head's sex, living arrangements, place of residence, marital status, and country of survey. All analyses were conducted separately for males and females. Results At the bivariate level, all independent variables (except for coerced sex among males were associated with the outcome variable. Overall, 9% of adolescents reported that they had been drunk in the 12 months preceding the survey. In general, respondents who had experienced an adverse event during childhood were more likely to report drunkenness. In the multivariate analysis, only two adverse childhood events emerged as significant predictors of self-reported past-year drunkenness among males: living in a household with a problem drinker before age 10, and being physically abused before age 10. For females, exposure to family-alcoholism, experience of physical abuse, and coerced sex increased the likelihood of reporting drunkenness in the last 12 months. The association between adverse events and reported drunkenness was more pronounced for females. For both males and females there was a graded relationship between the number of

    Medical product information contains information about efficacy and safety for marketed pharmaceuticals. Three studies have compared safety labelling for different therapeutic categories in different countries and detected large variations in a number of reported adverse drug reactions (ADRs). The rapid increase in use of medications for treatment of ADHD symptoms has created concern due to lack of information about effects from long-term use. The aim of this study was to compare ADR information in product information (PI)/summary of product characteristics (SPC) for oral formulations of atomoxetine, methylphenidate and modafinil marketed by the same pharmaceutical companies in Australia, Denmark and the United States. Discrepancies in listed ADRs were defined as types of ADRs (system organ class) not listed in all countries. For ADRs where discrepancies were detected, we extracted information about study design (clinical trials, spontaneous report). Discrepancies in ADR labelling for the medications were found across the three countries. A total of 75 ADR categories were listed for atomoxetine and 80% of these were listed in all three countries. For methylphenidate, totally 101 ADR categories and for modafinil 115 ADR categories were listed. For both substances approximately 60% of listed ADRs were found in all three countries. Discrepancies were primarily detected for ADRs information based on clinical trials. For methylphenidate, many ADRs labelled in Australia and Denmark were not mentioned in PIs issued in the United States. In conclusion, information about possible ADRs associated with the use of a specific product should be made available worldwide, as the prescriber information about medicines' safety profile should not depend on the country in which the medication is licensed.
