    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...... reported from other sources, in terms of their type, seriousness and the suspected medicines involved. METHODS: The number of ADRs reported to the Danish ADR database from 2004 to 2006 was analysed in terms of category of reporter, seriousness, category of ADRs by system organ class (SOC) and the suspected...... 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...

    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.

    Aim The aim of the study was to assess patient knowledge on reporting of adverse drug reactions. Materials and methods A prospective study was conducted among 200 patients. The study was based on an original survey composed of 15 single- and multiple-choice questions. The study involved individuals who have experienced adverse reactions as well as individuals who have never experienced any adverse reactions; people over the age of 18; literate; residing in Mazowieckie Voivodeship, who have not been diagnosed with any disease that could compromise their logical thinking skills. Results The respondents who lived in the city had a greater knowledge compared to the respondents who lived in the countryside (Pearson’s χ2=47.70, P=0.0013). The respondents who lived in the city were also more statistically likely to provide a correct answer to the question about the type of adverse reactions to be reported (Pearson’s χ2=50.66, P=0.012). Statistically significant associations were found between the place of residence of the respondents and the correct answer to the question about the data that must be included in the report on adverse reactions (Pearson’s χ2=11.7, P<0.0001).

    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

  9. Canada's Adverse Drug Reaction Reporting System: A Failing Grade.

    2015-01-01

    An article in the National Post on suicidal effects associated with varenicline (Champix) highlights deficiencies in the Canadian spontaneous reporting system (SRS) for adverse drug reactions (ADRs). The issues of under-reporting, poor quality information, duplication of reports and lack of a population denominator of drug use are discussed. Canada's SRS is deficient. There are immediate and medium-term actions that could be instituted that would improve pharmacovigilance in Canada. However, education about appropriate prescribing, the recognition of ADRs, and the duty to report them is a key long-term strategy to improving the pharmacovigilance system and should be included at every opportunity in the training of healthcare professionals so that life-long habits are developed. In addition to changes at Health Canada, greater emphasis needs to be placed on training in therapeutics, understanding drug safety, and the responsibility of healthcare providers in reporting risks in the curricula of medical and nursing schools.

    We received 105 reports of suspected adverse events (SARs) following the use of veterinary drugs for the year 2005. This corresponds to a 35% increase compared to 2004. Practicing veterinarians sent most of these declarations. 73% of these concerned drugs used on companion animals. Antiparasitic drugs approved for topical use were the most frequently represented group with 48%, followed by drugs used to treat gastrointestinal disorders (11%) and drugs used off-label (14%; other target species or other indication). For the first time 2 declarations concerning the application of permethrin containing spot-on preparations used by mistake on cats were received. An overview of 20 declarations about adverse reactions following application of different vaccines is also presented with emphasis on the problem of fibrosarcoma in cats. We are pleased by the growing interest shown by practicing veterinarians for the vigilance system and hope to further develop this collaboration in the future.

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

    2007-02-01

    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.

Improvement in current ADR reporting, including utility of underused or innovative methods, is crucial to improve patient safety and public health.Objectives: To evaluate methods to improve ADR reporting via a systematic literature review.Methods: Data sources were Medline, Embase, Cochrane Library and National Library for health searches on ADR reporting (January 1997 to August 2007 including cross-referenced articles. Twenty-four out of 260 eligible studies were identified and critically assessed. Studies were grouped as follows: i spontaneous reporting (11; ii medical chart/note review (2; iii patient interviews/questionnaires (3; and iv combination methods including computer-assisted methods (8.Results: Using computerized monitoring systems (CMS to generate signals associated with changes in laboratory results with other methods can improve ADR reporting. Educational interventions combined with reminders and/or prescription card reports can improve hospitalbased ADR reporting, and showed short to medium term improvement.Conclusions: The use of electronic health data combined with other methods for ADR reporting can improve efficiency and accuracy for detecting ADRs and can be extended to other health care settings. Although methods with educational intervention appear to be effective, few studies have reviewed long-term effects to assess if the improvements can be sustained.

  13. Bias in spontaneous reporting of adverse drug reactions in Japan.

    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.

    Under the auspices of the Council for International Organizations of Medical Sciences, a working group composed of representatives of seven multinational pharmaceutical manufacturers and six regulatory authorities developed and implemented a standardized method for reporting post-approval adverse drug reactions (ADR). The method is based on a set of uniform definitions and procedures and a single reporting form, and has been demonstrated to be feasible and effective. Regulators and manufacturers, in establishing requirements and systems for reporting of adverse drug reactions, should consider adopting this method.

    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.

    2013-01-01

    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.

    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 Medications used to treat human ailments are known to cause cutaneous reactions which may vary in their severity. Leflunomide, an immunomodulating agent recently introduced to treat rheumatoid arthritis, is reported to cause severe cutaneous reactions. We are reporting five such cases. All our patients were started on leflunomide for rheumatoid arthritis, 4-6 weeks before the onset of cutaneous reaction and were admitted to the hospital with the common complaints of fever, skin rash and generalized weakness. All of them had characteristic pattern of events such as delayed onset of reaction, widespread and long lasting skin rash and internal organ involvement. These features suggest a possibility of drug hypersensitivity syndrome to leflunomide. Careful dosing and periodic monitoring of patients treated with leflunomide for possible adverse drug reaction is recommended.

    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.

    Background Information about medicines safety in children is very limited. Consumer adverse drug reaction (ADR) reports can provide information about serious and unknown ADRs from medicine use in children. Objective To characterize ADRs in children reported by consumers in Europe from 2007 to 2011...... agents for 23 % and sex hormones for 13 %. Conclusion Only few paediatric ADR consumer reports were found in EudraVigilance. Many of these ADRs were serious, and fatal cases were reported, however also nonserious reports were present. The findings indicate that consumer reports may be of value....... Methods We analysed ADRs reported to the European ADR database, EudraVigilance (EV) for individuals from birth to 17 years. Data were characterized with respect to age and sex of the child, type of ADR (system organ class and preferred term), seriousness and suspected medicines (anatomical therapeutic...

    Introduction: Adverse drug reactions can cause increased morbidity and mortality, and therefore information needs to be studied systematically. Little is known about the adverse drug reactions for chronic obstructive pulmonary disease therapy. The goal of this study is to assess the expectedness, seriousness and severity of adverse drug reactions during chronic obstructive pulmonary disease therapy based on their reporting in the national pharmacovigilance system. Methods: This was a prospective, observational, 1-year, real-life study about the pharmacotherapy of a sample of 390 chronic obstructive pulmonary disease patients. Prescribed medicines were systematized and national pharmacovigilance databases were searched for reported adverse drug reactions. The expectedness was evaluated through the review of the summary of product characteristics, the seriousness was evaluated by the clinicians based on the life threatening nature of the adverse drug reactions, and the severity was evaluated through Hartwig’s Severity Assessment Scale. Descriptive statistics of the reported adverse drug reactions was performed and the relative risk of developing an adverse drug reaction with all international non-proprietary names included in the analysis was calculated. Results: Results confirm that the chronic obstructive pulmonary disease is a disease with high appearance of adverse drug reactions, and causes many additional costs to the healthcare system. Unexpected and severe adverse drug reactions are frequent. A total of 4.8% of adverse drug reactions were evaluated as life threatening. Majority of adverse drug reactions are classified in Levels 1 (32.6%), 2 (26.4%) and 3 (19%) according to Hartwig’s Severity Assessment Scale. Approximately 22% of reported adverse drug reactions affect people’s everyday life to a greater extent and require additional therapy which might further increase the risk. The relative risk of developing an adverse drug reaction was highest for

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

    Full Text Available New drugs are regularly introduced for treatment, diagnosis or prevention of diseases. Adverse drug reactions (ADR can be seen in clinical practice with both new as well as marketed medicines. Spontaneous reporting of ADR is commonly practiced method for monitoring of ADR. Healthcare practitioners have an important role in pharmacovigilance and ADR reporting. Many studies have been conducted to understand the knowledge, attitude and practice of ADR reporting among healthcare practitioners in India. The population surveyed in these studied ranged between 90-1200. One large study4 included population of 1200 physicians across India out of which 1000 were contacted for study participation.

    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.

    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.

    Full Text Available Despite comprehensive and stringent phases of clinical trials and surveillance efforts, unexpected and serious adverse drug reactions (ADRs repeatedly occur after the drug is marketed. ADR reporting is an important aspect of an efficient and effective pharmacovigilance program. Although Medwatch, Yellow Card, CDSCO form, etc. are the protocol forms of ADR collection and reports, a number of countries design and use their respective ADR forms. This review compares similarities and dissimilarities of 13 ADR forms of countries representing their geographical location. This study extracted 73 data elements mentioned in 13 different ADR forms. Only 13 elements were common. An ADR form of Malaysia and Canada covers the highest number of data 43, while Brazil falls to the opposite end with a number of 17 data elements in lieu with the Generic ADR Form. The result of this review highlights 58 data elements of the proposed generic ADR form which ensures that requisite reporting information essential for correct causality assessment of ADRs are included. The proposed "Generic ADR form" could be adopted worldwide mandatorily for reporting any/all ADRs associated with marketed drugs.

    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

    Full Text Available To evaluate the clinical manifestations and causative drugs associated with adverse drug reactions (ADRs spontaneously reported by community pharmacists and to compare the ADRs by age.ADRs reported to the Regional Pharmacovigilance Center of the Korean Pharmaceutical Association by community pharmacists from January 2013 to June 2014 were included. Causality was assessed using the WHO-Uppsala Monitoring Centre system. The patient population was classified into three age groups. We analyzed 31,398 (74.9% ADRs from 9,705 patients, identified as having a causal relationship, from a total pool of 41,930 ADRs from 9,873 patients. Median patient age was 58.0 years; 66.9% were female.Gastrointestinal system (34.4%, nervous system (14.4%, and psychiatric (12.1% disorders were the most frequent symptoms. Prevalent causative drugs were those for acid-related disorders (11.4%, anti-inflammatory products (10.5%, analgesics (7.2%, and antibacterials (7.1%. Comparisons by age revealed diarrhea and antibacterials to be most commonly associated with ADRs in children (p < 0.001, whereas dizziness was prevalent in the elderly (p < 0.001. Anaphylactic reaction was the most frequent serious event (19.7%, mainly associated with cephalosporins and non-steroidal anti-inflammatory drugs. Among 612 ADRs caused by nonprescription drugs, the leading symptoms and causative drugs were skin disorders (29.6% and non-steroidal anti-inflammatory drugs (16.2%, respectively.According to the community pharmacist reports, the leading clinical manifestations and causative drugs associated with ADRs in outpatients differed among age groups.

    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.

    The primary aim of spontaneous reporting systems (SRSs) is the timely detection of unknown adverse drug reactions (ADRs), or signal detection. Generally this is carried out by a systematic manual review of every report sent to an SRS. Statistical analysis of the data sets of an SRS, or quantitative signal detection, can provide additional information concerning a possible relationship between a drug and an ADR. We describe the role of quantitative signal detection and the way it is applied at the Netherlands Pharmacovigilance Centre Lareb. Results of the statistical analysis are implemented in the traditional case-by-case analysis. In addition, for data-mining purposes, a list of associations of ADRs and suspected drugs that are disproportionally present in the database is periodically generated. Finally, quantitative signal generation can be used to study more complex relationships, such as drug-drug interactions and syndromes. The results of quantitative signal detection should be considered as an additional source of information, complementary to the traditional analysis. Techniques for the detection of drug interactions and syndromes offer a new challenge for pharmacovigilance in the near future.

    Safety information regarding drug use during pregnancy is insufficient. The present study aimed to establish an optimal signal detection method to identify adverse drug reactions in pregnant women and to evaluate information in the Japanese Adverse Drug Event Report (JADER) database between April 2004 and November 2014. We identified reports on pregnant women using the Standardised MedDRA Queries. We calculated the proportional reporting ratio (PRR) and reporting odds ratio (ROR) of the risk factors for the two known risks of antithyroid drugs and methimazole (MMI) embryopathy, and ritodrine and fetal/infant cardiovascular events. The PRR and ROR values differed between all reports in the JADER database and those on pregnant women, affecting whether signal detection criteria were met. Therefore we considered that reports on pregnant women should be used when risks associated with pregnancy were determined using signal detection. Analyses of MMI embryopathy revealed MMI signals [PRR, 159.7; ROR, 669.9; 95% confidence interval (CI), 282.4-1588.7] but no propylthiouracil signals (PRR, 1.98; ROR, 2.0; 95%CI, 0.3-15.4). These findings were consistent with those of reported risks. Analyses of fetal/infant cardiovascular events revealed ritodrine signals (PRR, 2.1; ROR, 2.1; 95%CI, 1.4-3.3). These findings were also consistent with reported risks. Mining the JADER database was helpful for analyzing adverse drug reactions in pregnant women.

    Hauben, Manfred; Hung, Eric; Hsieh, Wen-Yaw

    2016-01-01

    Background: Severe cutaneous adverse reactions (SCARs) are prominent in pharmacovigilance (PhV). They have some commonalities such as nonimmediate nature and T-cell mediation and rare overlap syndromes have been documented, most commonly involving acute generalized exanthematous pustulosis (AGEP) and drug rash with eosinophilia and systemic symptoms (DRESS), and DRESS and toxic epidermal necrolysis (TEN). However, they display diverse clinical phenotypes and variations in specific T-cell immune response profiles, plus some specific genotype–phenotype associations. A question is whether causation of a given SCAR by a given drug supports causality of the same drug for other SCARs. If so, we might expect significant intercorrelations between SCARs with respect to overall drug-reporting patterns. SCARs with significant intercorrelations may reflect a unified underlying concept. Methods: We used exploratory factor analysis (EFA) on data from the United States Food and Drug Administration Adverse Event Reporting System (FAERS) to assess reporting intercorrelations between six SCARs [AGEP, DRESS, erythema multiforme (EM), Stevens–Johnson syndrome (SJS), TEN, exfoliative dermatitis (ExfolDerm)]. We screened the data using visual inspection of scatterplot matrices for problematic data patterns. We assessed factorability via Bartlett’s test of sphericity, Kaiser-Myer-Olkin (KMO) statistic, initial estimates of communality and the anti-image correlation matrix. We extracted factors via principle axis factoring (PAF). The number of factors was determined by scree plot/Kaiser’s rule. We also examined solutions with an additional factor. We applied various oblique rotations. We assessed the strength of the solution by percentage of variance explained, minimum number of factors loading per major factor, the magnitude of the communalities, loadings and crossloadings, and reproduced- and residual correlations. Results: The data were generally adequate for factor analysis

    Full Text Available Context: Herbal drugs are a mixture of active compounds and the chemical complexity of each formulation increase with the possibility of interactions between them and conventional drugs. Many mechanisms are implicated in the interactions; scientific community has dedicated the attentions to enzymes as P-gp and CYP450. Aims: To investigate in the literature the principal plants with suspicions of adverse reactions in Cuba and their potential interactions with conventional drugs. Methods: PubMed was the database used as source of information until February 2014. Key words: Herb-Drug, Drug-Plant, Herbal–Drug, Interactions with scientific names of plants was used. Information was structured and analysed with EndNote X4. Analysis and integration of the information: Allium sativum L. (garlic was the plant with the high number of studies related with CYP450 and P-gp. Plants with great demand as Morinda citrifolia L. (noni, Psidium guajava L. (guayaba, Zingiber officinale Roscoe (ginger and Eucalyptus spp. (eucalyptus have a very small number of studies. The professionals of the health should keep in mind the possibility of interactions between herbal products and conventional drugs to increase the effectiveness of phytotherapy. Conclusions: It is necessary enhance reports and investigations and to put to disposition of the system of health information on the interactions of plants and to stimulate the investigation that offers information for the rational use of our medicinal plants.

    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.

    Cutaneous adverse reactions to antiepileptic drugs (AEDs) are usually easily recognized in daily clinical practice when they manifest as a morbilliform or maculopapular rash within the first few weeks after introducing an AED. Valproate (VPA)-induced encephalopathy is a rare but serious complication, presenting with impaired consciousness, with or without hyperammonemia, normal liver enzymes, and normal serum level of VPA. A 2-year-old Caucasian boy with severe developmental disability and pharmacoresistant epilepsy presented with fever, generalized erythrodermia, and encephalopathy, which resolved after discontinuation of valproate. Sodium valproate (30 mg/kg/day) was introduced 5 months previously, as the third drug in combination with vigabatrin and levetiracetam, due to frequent daily seizures. The clinical condition of generalized erythrodermia and encephalopathy was recognized by the treating physician as a possible adverse reaction to VPA: with the Naranjo scale it was probably associated with VPA (six points) and possibly associated with vigabatrin and levetiracetam (three and two points, respectively). After valproate withdrawal, the patient recovered completely. This case is of interest because erythrodermia was a clue to the recognition of valproate-related adverse reaction with severe central nervous system involvement without hyperammonemia and with normal liver enzymes--a very rare occurrence.

    Full Text Available Introduction: Pharmacovigilance is an arm of patient care. No one wants to harm patients, but unfortunately any medicine will sometimes do just this. Underreporting of adverse drug reactions by healthcare professionals is a major problem in many countries. In order to determine whether our pharmacovigilance system could be improved, and identify reasons for under-reporting, a study to investigate the role of health care professionals in adverse drug reaction (ADR reporting was performed.Methods: A pretested questionnaire comprising of 20 questions was designed for assessment of knowledge, perceptions, practice and barriers toward ADR reporting on a random sample of 1000 healthcare professionals in Bosnia and Herzegovina.Results: Of the 1000 respondents, 870 (87% completed the questionnaire. The survey showed that 62.9% health care professionals would report ADR to the Agency for Medicinal Products and Medical Device of Bosnia and Herzegovina (ALMBIH. Most of surveyed respondents has a positive perception towards ADR reporting, and believes that this is part of their professional and legal obligation, and they also recognize the importance of reporting adverse drug reactions. Only small percent (15.4% of surveyed health care professionals reported adverse drug reaction.Conclusions: The knowledge of ADRs and how to report them is inadequate among health care professionals. Perception toward ADR reporting was positive, but it is not reflected in the actual practice of ADRs, probably because of little experience and knowledge regarding pharmacovigilance. Interventions such as education and training, focusing on the aims of pharmacovigilance, completing the ADR form and clarifying the reporting criteria are strongly recommended.

    The purpose of this study was to report severe cutaneous reactions in two patients related with leflunomide. A 13-year-old girl was treated with leflunomide for systemic lupus erythematosus. Three months later a progressive generalized blistering formation occurred and epidermolysis appeared on her skin. Methylprednisolone pulse therapy and intravenous immunoglobulin were used to control the severe cutaneous reactions. The patient recovered within 18 days. Another case is a 63-year-old woman who was treated with leflunomide for primary Sjögren's syndrome. Four months later widespread prunosus skin rash appeared on her skin. Methylprednisolone pulse therapy was also used to control the severe cutaneous reactions. The patient was recovered 11 days later. Our report suggests that an association between leflunomide intake and severe cutaneous reactions in rheumatic disease patients should be considered.

    Full Text Available Background. Adverse drug reactions are global problems of major concern. Adverse drug reaction reporting helps the drug monitoring system to detect the unwanted effects of those drugs which are already in the market. Aims. To assess the knowledge, attitude, and practice of health care professionals working in Nekemte town towards adverse drug reaction reporting. Methods and Materials. A cross-sectional study design was conducted on a total of 133 health care professionals by interview to assess their knowledge, attitude, and practice using structured questionnaire. Results. Of the total respondents, only 64 (48.2%, 56 (42.1%, and 13 (9.8% health care professionals have correctly answered the knowledge, attitude, and practice assessment questions, respectively. Lack of awareness and knowledge on what, when, and to whom to report adverse drug reactions and lack of commitments of health care professionals were identified as the major discouraging factors against adverse drug reaction reporting. Conclusion. This study has revealed that the knowledge, attitude, and practice of the health care professionals working in Nekemte town towards spontaneous adverse drug reaction reporting were low that we would like to recommend the concerned bodies to strive on the improvement of the knowledge, attitude, and practice status of health care professionals.

    This research based on the analysis of spontaneous reporting system (SRS) data which the 9 601 case reports of Shuxuening injection adverse drug reactions (ADR) in national adverse drug reaction monitoring center during 2005-2012. Apply to the association rules to analysis of the relationship between Shuxuening injection's ADR and the characteristics of ADR reports were. We found that ADR commonly combination were "nausea + breath + chills + vomiting", "nausea + chills + vomiting + palpitations", and their confidence level were 100%. The ADR and the case reports information commonly combination were "itching, and glucose and sodium chloride Injection, and generally ADR report, and normal dosage", "palpitation, and glucose and sodium chloride injection, and normal dosage, and new report", "chills, and generally ADR report, and normal dosage, and 0.9% sodium chloride injection", and their confidence level were 100% too. The results showed that patients using Shuxuening injection occurred most of ADRs were systemic damage, skin and its accessories damage, digestive system damage, etc. And most of cases were generally and new reports, and patients with normal dosage. The ADR's occurred had little related with solvent. It is showed that the Shuxuening injection occurred of ADR mainly related to drug composition. So Shuxuening injection used in clinical need to closely observation, and focus on the ADR reaction, and to do a good job of drug risk management.

  20. Adverse reactions to drug additives.

    There is a long list of additives used by the pharmaceutical industry. Most of the agents used have not been implicated in hypersensitivity reactions. Among those that have, only reactions to parabens and sulfites have been well established. Parabens have been shown to be responsible for rare immunoglobulin E-mediated reactions that occur after the use of local anesthetics. Sulfites, which are present in many drugs, including agents commonly used to treat asthma, have been shown to provoke severe asthmatic attacks in sensitive individuals. Recent studies indicate that additives do not play a significant role in "hyperactivity." The role of additives in urticaria is not well established and therefore the incidence of adverse reactions in this patient population is simply not known. In double-blind, placebo-controlled studies, reactions to tartrazine or additives other than sulfites, if they occur at all, are indeed quite rare for the asthmatic population, even for the aspirin-sensitive subpopulation.

    Adverse drug reactions (ADR) are underreported by doctors despite numerous efforts. We aimed to determine if establishing an "ADR reporting doctor's network" within a hospital would increase the quantity of ADRs reported by hospital doctors. One hundred hospital doctors joined the network. Email reminders were sent to network members during the 1 year study period, conveying information about ADRs reported, amusingly and pleasantly reminding them to report ADRs in minimal detail, by phone, email, text message or mail to the Clinical Pharmacology Unit, who would further complete the report. A total of 114 ADRs were reported during the study period in comparison to 48, 26, and 17 in the previous 3 years (2008, 2009, 2010, respectively). In the 3 years prior, doctors reported 41.7% of the reported ADRs whereas in the study period, doctors reported 74.3% of ADRs (P reports. Ninety seven percent of doctors' reports were of ADR network members. Thirty-four (34%) network members reported an ADR during the study period and 31 of the 34 reporters had never reported ADRs before becoming network members. Establishing an ADR network of doctors substantially increases ADR reporting amongst its members.

    Full Text Available Objectives: Spontaneous reporting is an important tool in pharmacovigilance. However, its success depends on cooperative and motivated prescribers. Under-reporting of adverse drug reactions (ADRs by prescribers is a common problem. The present study was undertaken to evaluate the knowledge, attitude, and practices (KAP regarding ADR reporting among prescribers at the Civil Hospital, Ahmedabad, to get an insight into the causes of under-reporting of ADRs. Materials and Methods: A pretested KAP questionnaire comprising of 15 questions (knowledge 6, attitude 5, and practice 4 was administered to 436 prescribers. The questionnaires were assessed for their completeness (maximum score 20 and the type of responses regarding ADR reporting. Microsoft Excel worksheet (Microsoft Office 2007 and Chi-Square test were used for statistical analysis. Results: A total of 260 (61% prescribers completed the questionnaire (mean score of completion 18.04. The response rate of resident doctors (70.7% was better than consultants (34.5% (P < 0.001. ADR reporting was considered important by 97.3% of the respondents; primarily for improving patient safety (28.8% and identifying new ADRs (24.6%. A majority of the respondents opined that they would like to report serious ADRs (56%. However, only 15% of the prescribers had reported ADRs previously. The reasons cited for this were lack of information on where (70% and how (68% to report and the lack of access to reporting forms (49.2%. Preferred methods for reporting were e-mail (56% and personal communication (42%. Conclusion: The prescribers are aware of the ADRs and the importance of their reporting. However, under reporting and lack of knowledge about the reporting system are clearly evident. Creating awareness about ADR reporting and devising means to make it easy and convenient may aid in improving spontaneous reporting.

Spontaneous reporting of adverse drug reactions (AD R is an important method in pharmacovigilance, but under-reporting is a major limitation. AIMS: Physicians being frontline caregivers this study was conducted to assess the knowledge, a ttitude and practice (KAP of ADR reporting among physicians in a tertiar y care hospital. SETTING AND DESIGN: This cross sectional, questionnaire based study was carried out amongst all the physicians working at Rajarajeswari Medical College & hospital, Bangalore over a period of 1 month. MATERIALS AND METHODS: A questionnaire was prepared after a initial pilot st udy and was distributed among all the physicians. For every Phys ician 30 minutes was given to fill up the questionnaire. Later on the filled questionnaires w ere collected and analyzed as per the study objectives. RESULTS: A questionnaire was distributed to 189 physicians, but only 122 returned the questionnaire (response rate of 70.9% . This study revealed inadequate knowledge and poor practice of ADR reporting. Though 56.8% physician felt that they encountered ADRs, only 22.1% had actually ever reported an ADR. The most co mmon reasons of under reporting were lack of time(34.5%, followed by lack of knowledge of reporting procedure (30.4%. But the physicians showed positive attitude towards ADR report ing. 95.0% felt that that ADR reporting is necessary and 79.5% supported for establishing ADR monitoring centre in e very hospital. Most of the physicians (95.9% suggested that continuous medical education and training on ADR reporting is necessary for overcoming the problem of underreporting of ADRs. CONCLUSION: The study results revealed the existence of underr eporting of ADRs, but also the willingness of clinicians to be trained in ADR repor ting and contributing to the pharmacovigilance programme. It is desirable to initi ate workshops and

    Adverse drug reactions (ADRs) to antibiotics complicate the management of any infection, particularly opportunistic infections in advanced HIV as some ADRs are potentiated by HIV. Trimethoprim-sulfamethoxazole (TMP-SMX) causes ADRs in 40-80% of HIV infected individuals, compared to 3-5% in the general population. The incidence and severity of ADRs among HIV infected individuals appear to increase as they progress from latent infection to AIDS. We present a single case report of a 55-year-old African American male found to have an otherwise asymptomatic acute HIV infection who developed an ADR to TMP-SMX, despite having previously tolerating the medication. The proposed mechanisms for the increased incidence of sulfa hypersensitivity reactions among HIV infected individuals focus on either (1) HIV-induced changes in the immune function driven by falling levels of CD4 cells or (2) other HIV-specific factors correlated with rising viral load. To our knowledge this is the first reported case of new sulfa hypersensitivity in primary HIV and may provide clinical evidence to support the correlation between viral load and ADRs to TMP-SMX without a severely diminished CD4 count, though further research is necessary. This case also demonstrates a rare and easily overlooked presentation of HIV that may aid in early diagnosis.

  13. A critical evaluation of reports associating ayahuasca with life-threatening adverse reactions.

    2013-01-01

    Ayahuasca is a botanical hallucinogenic preparation traditionally consumed by Northwestern Amazonian indigenous groups. Scientific evidence suggests good tolerability after acute administration of ayahuasca and also after years or even decades of its ritual consumption. Nevertheless, some scientific and media reports associate ayahuasca or some of its alkaloids with severe intoxications. The purpose of the present text is to do a critical evaluation of these reports. The evaluation of the cases highlights the fact that some lack accurate forensic/toxicological information, while others are not directly relevant to traditional ayahuasca preparations. These limitations reduce the possibility of an accurate risk assessment, which could indicate potential contraindications and susceptibilities for ayahuasca consumption. Nevertheless, even with these limitations, the cases suggest that previous cardiac and hepatic pathologies and current use of serotonergic drugs/medications are contraindications to ayahuasca use, and that caution should be taken when using different botanical species and extracted/synthetic alkaloids to prepare ayahuasca analogues.

    Full Text Available AbstractBackground and purpose: Pharmacovigilance is a science that focuses on the detection, assessment, and prevention of adverse drug reactions (ADRs in the post-marketing phase. Its back bone is spontaneous reporting by health care workers via completing the yellow cards. Due to the low reporting of ADRs in the Mazandaran province, this study was designed to evaluate the knowledge, attitude and performance of pharmacists and nurses regarding ADRs reporting.Materials and Methods: This descriptive study was done on 286 health care workers including 67 pharmacists and 219 nurses, selected randomly from different cities of the province. The standard questionnaire of European pharmacovigilance research group was used as the data collection tool. In the field of knowledge, definition of pharmacovigilance, awareness of the national criteria for reporting the ADRs and awareness about the terminology occurrence rates of ADRs were questioned. To evaluate the attitude, reaction of subjects to the some simulated ADRs and reasons of underreporting were assessed. In the field of performance, numbers of reported ADRs and also the sites where reports sent from were asked. Data were analyzed using independent sample t-test for quantitative variables and Chi-square and Kendall’s tau-b for nominal and ordinal variables, respectively using SPSS software. P< 0.05 was considered as significant level.Results: There was no satisfying knowledge in each of the two groups. In spite of exposure of more than 80% of subjects to the ADRs, the mean reported ADRs values for pharmacists and nurses were very low as 0.72 ± 2.8 and 0.17 ± 0.67 respectively (P<0.01. Nurses liked to report most of ADRs to the physicians, nursing stations and pharmacist in spite of the national center. Considering these reports, they were more active than the pharmacists (P<0.001.

    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.

    2009-01-01

    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.

    The aim of the research was to assess the prevalence and pattern of self-reported adverse reactions to food and food allergies among primary schoolchildren in Vilnius. MATERIAL AND METHODS. Vilnius University was a partner in the EuroPrevall project. A total of 4333 schoolchildren from 13 primary schools participated in the study. Of all 4333 questionnaires distributed, 3084 were returned (response rate, 71.2%). This screening phase was followed by the second (clinical) part with an objective confirmative laboratory analysis of blood samples for the diagnosis of food allergy. For the research purposes, 186 blood samples for IgE were analyzed. RESULTS. Almost half of the children had an illness or a disorder caused by eating food. The prevalence of adverse reactions to food was found to be increasing with age from 6 to 10 years. Food allergy was diagnosed in 16.4% of children. Boys had food allergy more frequently than girls. Diarrhea or vomiting and a rash, urticarial rash, or itchy skin were the most commonly mentioned symptoms. Fruits, berries, and milk and dairy were found to be the most common foods to cause adverse reactions. The most relevant foods for children with IgE-mediated food allergy were cow's milk and hazelnuts. CONCLUSIONS. The prevalence of self-reported food hypersensitivity among primary schoolchildren was observed in almost half of the studied population. Fruits, berries, and milk and dairy were the most common foods to cause adverse reactions among primary schoolchildren in Lithuania. The determined differences in the prevalence of food hypersensitivity and IgE-mediated food allergy and associations with gender and age need further scientific analysis for the development of prognostic and diagnostic tools.

    Herbal medicines are perceived to be safe by the general public and medical practitioners, despite abundant evidence from clinical trials and case reports that show herbal preparations can have significant adverse effects. The overall impact of adverse events to herbal medicines in Australia is currently unknown. Post marketing surveillance of medications through spontaneous adverse drug reaction (ADR) reports to the Therapeutic Goods Administration (TGA) is one way to estimate this risk. The patterns of spontaneously reported ADRs provide insight to herbal dangers, especially when compared with patterns of a mechanistically similar conventional drug. The study compared the pattern of spontaneously reported ADRs to St. John's Wort (Hypericum perforatum), a common herbal treatment for depression which contains selective serotonin reuptake inhibitors (SSRI), to fluoxetine, a commonly prescribed synthetic SSRI antidepressant. Spontaneous ADR reports sent to the TGA between 2000-2013 for St. John's Wort (n = 84) and fluoxetine (n = 447) were obtained and analysed. The demographic information, types of interaction, severity of the ADR, and the body systems affected (using the Anatomical Therapeutic Chemical classification system) were recorded for individual ADR cases. The majority of spontaneously reported ADRs for St. John's Wort and fluoxetine were concerning females aged 26-50 years (28.6%, 22.8%). The organ systems affected by ADRs to St John's Wort and fluoxetine have a similar profile, with the majority of cases affecting the central nervous system (45.2%, 61.7%). This result demonstrates that herbal preparations can result in ADRs similar to those of prescription medications.

    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.

    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.

    2011-01-01

    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

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.

    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.

    Adverse drug reactions (ADR} are the downside of active pharmacotherapies and can only partially be avoided. Risk factors have been identified for certain ADR which should be taken into account for the choice and dosing of critical drugs. Medical staff have a legal obligation to report severe ADR and ADR caused by newly licensed drugs. Such reports are important for monitoring the safety of drugs that are on the market.

    Full Text Available Purpose: The goal of this study was to compare the knowledge and attitudes of pharmacy and medical students regarding adverse drug reactions (ADRs, as well as their perceptions of barriers to ADR reporting, in a Higher Education Commission-recognised Pakistani university. Methods: A cross-sectional study was conducted among final-year pharmacy (n=91 and medical (n=108 students in Pakistan from June 1 to July 31, 2014. A self-administered questionnaire was used to collect the data. The responses of pharmacy students were compared to those of medical students. Results: Pharmacy students had a significantly better knowledge of ADRs than medical students (mean±SD, 5.61±1.78 vs. 3.23±1.60; P<0.001. Gender showed a significant relationship to knowledge about ADRs, and male participants were apparently more knowledgeable than their female counterparts (P<0.001. The attitudes of pharmacy students regarding their capability to handle and report ADRs were significantly more positive than those of medical students (P<0.05. In comparison to pharmacy students, a lack of knowledge of where and how to report ADRs was the main barrier that medical students perceived to ADR reporting (P=0.001. Conclusion: Final-year pharmacy students exhibited more knowledge about ADRs and showed more positive attitudes regarding their capacity to handle and report ADRs than final-year medical students.

    Adverse Drug Reaction (ADR) is one of the most important issues in the assessment of drug safety. In fact, many adverse drug reactions are not discovered during limited pre-marketing clinical trials; instead, they are only observed after long term post-marketing surveillance of drug usage. In light of this, the detection of adverse drug reactions, as early as possible, is an important topic of research for the pharmaceutical industry. Recently, large numbers of adverse events and the developm...

    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. Participating physicians were able to incorporate the knowledge they had gained from face-to-face training into their

    Full Text Available Aim: The aim of the present study was to know the profile of adverse drug reactions (ADR, at ambulatory level, suffered by patients using amitrityline. 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 Background: Adverse drug reaction (ADR monitoring is slowly developing as an important aspect of healthcare. The aim of the study was to study the pattern of adverse drug reactions in the Oncology department of a tertiary care hospital. Materials And Methods: This was a prospective study conducted in the Oncology department of a tertiary care hospital in which ADRs were reported spontaneously. The ADRs were noted from 1st January, 2007 to 30th June, 2011. Following were noted: demographics, premedication (if any, diagnosis, chemotherapy (regimen, cycles, medication history, and alteration in the treatment or co morbidities, ADRs (severity and management. Adverse drug reactions were noted by patient interview, collaborating with information on file, recording changes in the prescribing chart and investigations, consulting the doctor on duty. Results: During this study period, there were total of 14,475 visits of patients from which 2500 ADRs were recorded. Maximum number of ADRs were noted with platinum compounds (25.52% followed by pyrimidine antagonists (19.88%. The most common malignancy reported in our hospital was Carcinoma breast (20% followed by leukemia (12% and Ca ovary (12%. Alopecia (27.76% was the most common ADR followed by anemia (7.48%, thrombocytopenia (6.96% and constipation (6.16%. Conclusion: Alopecia is the most common ADR and platinum compounds were responsible for the maximum number of ADRs. The most common carcinoma reported during this period was carcinoma breast.

    Full Text Available Abstract Background In spite of enhanced control efforts, malaria remains a major public health problem causing close to a million deaths annually. With support from several donors, large amounts of artemisinin-based combination therapy (ACT are being deployed in endemic countries raising safety concerns as little is known about the use of ACT in several of the settings where they are deployed. This project was undertaken to profile the provenance of the pharmacovigilance reporting of all anti-malarials, including ACT to the WHO adverse drug reaction (ADR database (Vigibase™ over the past 40 years. Methods The WHO Programme for International Drug Monitoring, the Uppsala Monitoring Centre (UMC provided anonymized extracts of Vigibase™ covering the period 1968-2008. All countries in the programme were clustered according to their malaria control phase and income status. The number of individual case safety reports (ICSRs of anti-malarials was analyzed according to those clusters. Results From 1968 to 2008, 21,312 ICSRs suspecting anti-malarials were received from 64 countries. Low-income countries, that are also malaria-endemic (categorized as priority 1 countries submitted only 1.2% of the ICSRs. Only 60 out of 21,312 ICSRs were related to ACT, 51 of which were coming from four sub-Saharan African countries. Although very few ICSRs involved artemisinin-based compounds, many of the adverse events reported were potentially serious. Conclusions This paper illustrates the low reporting of ADRs to anti-malarials in general and ACT in particular. Most reports were submitted by non-endemic and/or high-income countries. Given the current mix of large donor funding, the insufficient information on safety of these drugs, increasing availability of ACT and artemisinin-based monotherapies in public and private sector channels, associated potential for inappropriate use and finally a pipeline of more than 10 new novel anti-malarials in various stages of

    2011-06-01

    Quinolones are a class of antibacterial agents for the treatment of several infectious diseases (e.g. urinary and respiratory tract infections). They are used worldwide due to their broad spectrum of activity, high bioavailability and good safety profile. The safety profile varies from quinolone to quinolone. The aim of this article was to review the neurological and psychiatric adverse drug reaction (ADR) profile of quinolones, using a literature search strategy designed to identify case reports and case series. A literature search using PubMed/MEDLINE (from inception to 31 October 2010) was performed to identify case reports and case series related to quinolone-associated neurological and psychiatric ADRs. The search was conducted in two phases: the first phase was the literature search and in the second phase relevant articles were identified through review of the references of the selected articles. Relevant articles were defined as articles referring to adverse events/reactions associated with the use of any quinolone. Abstracts referring to animal studies, clinical trials and observational studies were excluded. Identified case reports were analysed by age group, sex, active substances, dosage, concomitant medication, ambulatory or hospital-based event and seriousness, after Medical Dictionary for Regulatory Activities (MedDRA®) coding. From a total of 828 articles, 83 were identified as referring to nervous system and/or psychiatric disorders induced by quinolones. 145 individual case reports were extracted from the 83 articles. 40.7% of the individual case reports belonged to psychiatric disorders only, whereas 46.9% related to neurological disorders only. Eight (5.5%) individual case reports presented both neurological and psychiatric ADRs. Ciprofloxacin, ofloxacin and pefloxacin were the quinolones with more neurological and psychiatric ADRs reported in the literature. Ciprofloxacin has been extensively used worldwide, which may explain the higher number

    2013-02-01

    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.

    Full Text Available Thrombolytic agents are among the medications that are used widely for the treatment of thromboembolic disorders and myocardial infarction (MI. Despite the world-wide availability of newer specific agents, streptokinase (SK is still the most frequently used medication from this class in Iran. Hence we conducted this study to review the adverse reactions to this medication which were reported in the Iranian studies. We preformed this study by searching the English resources such as Pubmed, Google scholar and Scopus. Additionally, we searched Google scholar, Scientific Information Database, Magiran and IranMedex to cover Persian articles.We found 50 articles from the mentioned resources after deleting the duplicated records. Nineteen articles remained after implementing the inclusion and exclusion criteria. In most of the studies the indication for SK treatment was MI. Assessment of streptokinase ADRs was the main focus of 7 studies. The most frequent adverse drug reaction (ADR was related to the cardiovascular system. Among them arrhythmia and hypotension were the most frequent ones. The second most prevalent ADR was bleeding followed by allergic reactions. In two studies only a single system ADR was studied: neurologic adverse effects and elevation in liver enzymes. Only very limited number of studies assessed the causality of the ADRs which made the interpretation of the results difficult. Among the associated factors that were assessed as risk factors of ADRs, age was the focus of 2 studies. The Iranian studies reported frequent ADRs similar to previous reports. However, due to the heterogeneity of the studies we could not describe the frequency and severity of reported ADRs in a more clear and precise conclusion.

    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.

    Using Chinese Materia Medica (CM) as injections is an innovation that is proving effective in extensive clinical use in Mainland China. However, recent reports have focused on adverse reactions, ignoring the considerable successes of these preparations. In order to achieve balance in the media and in the minds of the public, we suggest the first step is to clarify the concepts of and differences between adverse drug reactions (ADR) and adverse events (AE) for all concerned-the public, medical practitioners, government officials, and lawmakers. Second, the State Food and Drug Administration should raise the requirements for Chinese Materia Medica Injection (CMI) registration and license approval and emphasize the importance of evidence-based CMI development and evidence-based CMI license approval. Thirdly, drug companies and institutions should reinforce basic research about the quality control of herbs and CMI-drug interactions. Fourth, the Government should clarify the legal responsibilities for CMI approval agencies, CMI developers, medical doctors, and patients. Fifth, the medical association and Government should enhance training for health care professionals concerning the usage of CMIs. And finally sixth, State Food and Drug Administration should monitor the content and quality of the directions for use of CMI.

    Since the state food and drug administration (SFDA) issued the first edition of adverse drug reaction(ADR) information in November, 2001, it has 32 edition, reported the drug 66 species of adverse reactions, involving the variety of 12 traditional Chinese medicines, it was effectively reminds all social concern of adverse drug reaction. For statistical analysis in recent years reported adverse drug reaction of prepared Chinese medicine, collected 462 literatures from 2005-09 CNKI Chinese journal full-text database of medicine health directory. In all the collections, about 94 literatures are closely related to adverse drug reaction report of prepared Chinese medicine. But there are only 7 references could identify traditional Chinese medicine and western medicine correctly in 72 literatures with the value of statistical analysis. That means only 8.9% of literatures can correctly identify western medicine and Chinese traditional medicine. So it proved that TCM workers' knowledge of ADR remains to be greatly improved.

    Adverse drag reactions (ADRs) are estimated to be one of the leading causes of death. Many national and international agencies have set up databases of ADR reports for the express purpose of determining the relationship between drugs and adverse reactions that they cause. We formulate the drug-reaction relationship problem as a continuous optimization problem and utilize C-GRASP, a new continuous global optimization heuristic, to approximately determine the relationship between drugs and adverse reactions. Our approach is compared against others in the literature and is shown to find better solutions.

    BACKGROUND: Information on ethnic diversity of adverse drug reactions (ADRs) to asthma medications is rare despite evidence suggesting higher risk for African Americans when using β2-adrenergic receptor agonists. The objectives are to investigate how ethnic background was involved in ADR assessment...... and to examine the relationship between ethnic background and ADRs to asthma medications. METHODS: MEDLINE was searched until March 2014. All types of studies reporting ADRs to asthma medications involving more than one ethnic group were included. Extracted information includes study designs, ethnic backgrounds...... statistically insignificant or inconclusive. CONCLUSIONS: Ethnicity was largely overlooked. Most studies neglected to report ADRs by ethnicity. Lack of consistency in defining ethnicities complicated further pooled analyses. Despite the higher prevalence of asthma among specific ethnic minority groups, few...

    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.

    In this report we describe a 53-year-old woman with advanced non-small cell lung cancer, treated with pemetrexed and cisplatin combination therapy, followed by pemetrexed monotherapy. The patient developed severe muscle spasms at least twice, shortly after administration of pemetrexed monotherapy. A possible explanation for this observation is that in combination with cisplatin therapy, the patient was hyperhydrated before administration to promote renal excretion and reduce toxicity. Pemetrexed is also renally excreted, which supports the finding that toxicity did not occur when the patient was hyperhydrated. After discontinuation of pemetrexed the symptoms did not reoccur. All aspects of this case point to a possible relationship between pemetrexed and an adverse drug reaction (ADR). We conclude that muscle spasms are a rare, but possibly dose-related ADR of pemetrexed-based therapy. PMID:28203304

    Drugs administered as therapy for rheumatological disorders are a relatively common cause of adverse events. Important data regarding the effects of drugs on patients with rheumatological conditions is being lost or rendered inaccessible because of deficiencies in classification, measurement, and collection methods for adverse drug reactions. A significant number of adverse reactions to drugs will not be known before marketing, and hence vigilance on the part of clinicians and patients in observing and documenting these reactions is paramount in building our knowledge and modifying our practice accordingly. A variety of systems and methods for detecting adverse drug reactions are described, critically evaluated, and compared for cost, potential bias, ethical concerns, and subject recruitment required for necessary statistical power. Systems need to be developed to give access to the wealth of clinical experimental data available in the individual practices of a broad spectrum of clinicians. To facilitate this, representative organizations need to make adverse drug reactions a high priority as well as contributing expertise and finance to database formulation and accessibility.

    Full Text Available Many hospitalizations in India are due to Adverse Drug Reactions (ADR and resulting in morbidity and mortality in majority cases in addition to the huge economic burden. A survey was conducted to assess the knowledge, attitude and behavior of community pharmacists towards ADR related aspects. One hundred and twenty eight pharmacists from various Community pharmacies in two Districts of South India were consented in this survey. A questionnaire was prepared to investigate the knowledge, attitude and behavior of pharmacists regarding ADR reporting and distributed to the identified pharmacies. The data was collected and analyzed by ANOVA and t- test. Out of 342 community pharmacies approached, 128 (37.4% community pharmacists consented to be part of the survey and the questionnaire given was filled and returned by them. Out of these respondents, only 39 (30.5% pharmacists had knowledge about ADR, 15 (11.7% and 14 (10.9% were aware of National Pharmacovigilance Program (NPP and regional reporting centers respectively. Only 54 (43% agreed that ADR reporting is a professional obligation of pharmacist and none of the respondents reported ADRs. The main reason for not reporting any ADR was ‘they did not know how to report’ and ‘did not feel its beneficial’. This survey revealed that the community pharmacists were having least scores towards knowledge, attitude and behavior on ADRs in Indian Scenario.

    Currently, the incidence of tattooing is on the rise compared to the past, especially among adolescents, and it leads to the urgency of monitoring the security status of tattooing centers, as well as to inform people about the risks of tattoo practice. In our clinical experience, 20% of tattooed patients presented adverse reactions, like allergic contact dermatitis, psoriasis with Koebner's phenomena and granulomatous reactions, with the latter most prevalent and most often related to red pigment. Adverse reactions to tattoo pigments, especially the red one, are well known and described in literature. Great attention has to be focused on the pigments used, especially for the presence of new substances, often not well known. For this reason, we decided to perform a study on 12 samples of red tattoo ink, obtained by patients affected by different cutaneous reactions in the site of tattoo, to analyze their chemical composition.

    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...

    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.

    Adverse Drug Reaction (ADR) is one of the most important issues in the assessment of drug safety. In fact, many adverse drug reactions are not discovered during limited pre-marketing clinical trials; instead, they are only observed after long term post-marketing surveillance of drug usage. In light of this, the detection of adverse drug reactions, as early as possible, is an important topic of research for the pharmaceutical industry. Recently, large numbers of adverse events and the development of data mining technology have motivated the development of statistical and data mining methods for the detection of ADRs. These stand-alone methods, with no integration into knowledge discovery systems, are tedious and inconvenient for users and the processes for exploration are time-consuming. This paper proposes an interactive system platform for the detection of ADRs. By integrating an ADR data warehouse and innovative data mining techniques, the proposed system not only supports OLAP style multidimensional analysis of ADRs, but also allows the interactive discovery of associations between drugs and symptoms, called a drug-ADR association rule, which can be further developed using other factors of interest to the user, such as demographic information. The experiments indicate that interesting and valuable drug-ADR association rules can be efficiently mined.

    Surveillance of adverse events following immunisation (AEFI) is an essential component of vaccine safety monitoring. The most commonly utilized passive surveillance systems rely predominantly on reporting by health care providers (HCP). We reviewed adverse event reports received in Victoria, Australia since surveillance commencement in July 2007, to June 2013 (6 years) to ascertain the contribution of consumer (vaccinee or their parent/guardian) reporting to vaccine safety monitoring and to inform future surveillance system development directions. Categorical data included were: reporter type; serious and non-serious AEFI category; and, vaccinee age group. Chi-square test and 2-sample test of proportions were used to compare categories; trend changes were assessed using linear regression. Consumer reporting increased over the 6 years, reaching 21% of reports received in 2013 (PConsumer reports were 5% more likely to describe serious AEFI than HCP (P=0.018) and 10% more likely to result in specialist clinic attendance (Preporting increased to 32% of all report since its introduction in 2010, 85% of consumers continued to report by phone. Consumer reporting of AEFI is a valuable component of vaccine safety surveillance in addition to HCP reporting. Changes are required to AEFI reporting systems to implement efficient consumer AEFI reporting, but may be justified for their potential impact on signal detection sensitivity.

    @@ 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 The database of the New Zealand Centre for Adverse Reactions Monitoring (CARM is an example of the practice-based evidence discussed in the June issue of the Journal of Primary Health Care. Databases of reported adverse drug reactions (ADRs were established to generate hypotheses to be tested about previously unrecognised adverse reactions and interactions. Occasionally they are sufficient evidence in themselves. They can also identify prescribing practices that might increase the potential for ADRs to occur and provide feedback into guidelines in terms of the consequences of their use or non-use. Well-documented ADR reports can also highlight risk factors, thus providing a valuable contribution to risk benefit assessments in individual patients. Examples are discussed that support the use of ADRs as practice-based evidence in a non-hierarchical system in which case reports and case series, observational studies and randomised clinical trials contribute in a flexible relationship depending on the issue under investigation.

    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 .

    Tumor necrosis factor-α (TNF-α) inhibitors are increasingly being used as treatment for rheumatoid arthritis (RA). However, the administration of these drugs carries the risk of inducing injection site reaction (ISR). ISR gives rise to patient stress, nervousness, and a decrease in quality of life (QoL). In order to alleviate pain and other symptoms, early countermeasures must be taken against this adverse event. In order to improve understanding of the risk factors contributing to the induction of ISR, we evaluated the association between TNF-α inhibitors and ISR by applying a logistic regression model to age-stratified data obtained from the Food and Drug Administration Adverse Event Reporting System (FAERS) database. The FAERS database contains 7,561,254 reports from January 2004 to December 2015. Adjusted reporting odds ratios (RORs) (95% Confidence Intervals) were obtained for interaction terms for age-stratified groups treated with etanercept (ETN) and adalimumab (ADA). The adjusted RORs for ETN* ≥ 70 and ADA* ≥ 70 groups were the lowest among the age-stratified groups undergoing the respective monotherapies. Furthermore, we found that crude RORs for ETN + methotrexate (MTX) combination therapy and ADA + MTX combination therapy were lower than those for the respective monotherapies. This study was the first to evaluate the relationship between aging and ISR using the FAERS database. PMID:28260984

    The Department of Clinical Pharmacology in Jena is a pharmacovigilance center in a study on intensified spontaneous adverse drug reaction reporting. Physicians specialized in clinical pharmacology screen admissions to the Department of Internal Medicine for possible adverse drug reactions. Because of the collaboration between the Pharmacology Department and the nearby Poison Information Center (PIC) in Erfurt the question occurred whether the latter might contribute to adverse drug reaction monitoring. We compared the ADR registered by the intensified spontaneous reporting system in 1999 with those of the PIC during the same period. Each symptom observed was regarded as 1 case. Every suspected drug was also treated separately. The symptoms were classified using adverse reaction terminology. The drugs were classified according to the WHO Anatomical Therapeutic Chemical (ATC) classification index. The causality assessment was based upon bibliographic data and the method of Bégaud et al. [1985]. Only possible, probable or very probable ADR were compared. The PIC registered mainly psychiatric and nervous system disorders sedation and extrapyramidal disorders were the most frequent reactions - unlike the pharmacovigilance study which registered primarily gastrointestinal and heart rate disorders. The PIC registered mainly drugs used in the therapy of disorders of the central nervous system, i.e. mostly psycholeptics and drugs acting on the alimentary tract, mostly anticholinergics. Drugs for the therapy of sensory organs disorders were frequent owing to the systemic and local adverse drug effects of anticholinergic mydriatics. The PIC and pharmacovigilance centers can benefit from co-operation. The PIC provides easy access to qualified drug information and is thus a useful tool in ADR evaluation. Although the number of adverse reactions assessed was small, their evaluation revealed problems in drug usage which would not otherwise be reported. The evaluation has

    A 40-year-old man with no history of neuropsychiatric illness was taking one 250-mg tablet of mefloquine (MFQ) weekly for malaria prophylaxis while in Tanzania. He experienced no adverse reaction in association with his first two doses. Concurrently with both his third and his fourth dose he consumed about half a litre of whisky. On both occasions he experienced hallucinations, paranoid delusions and suicidal ideation. Thereafter he continued taking the MFQ, abstained completely from ethanol ingestion and had no recurrence of psychiatric symptoms. It is hypothesized that the combination of MFQ and ethanol caused the two episodes of severe psychiatric disturbance. PMID:7859199

    Full Text Available Abstract Background We would expect information on adverse drug reactions in randomised clinical trials to be easily retrievable from specific searches of electronic databases. However, complete retrieval of such information may not be straightforward, for two reasons. First, not all clinical drug trials provide data on the frequency of adverse effects. Secondly, not all electronic records of trials include terms in the abstract or indexing fields that enable us to select those with adverse effects data. We have determined how often automated search methods, using indexing terms and/or textwords in the title or abstract, would fail to retrieve trials with adverse effects data. Methods We used a sample set of 107 trials known to report frequencies of adverse drug effects, and measured the proportion that (i were not assigned the appropriate adverse effects indexing terms in the electronic databases, and (ii did not contain identifiable adverse effects textwords in the title or abstract. Results Of the 81 trials with records on both MEDLINE and EMBASE, 25 were not indexed for adverse effects in either database. Twenty-six trials were indexed in one database but not the other. Only 66 of the 107 trials reporting adverse effects data mentioned this in the abstract or title of the paper. Simultaneous use of textword and indexing terms retrieved only 82/107 (77% papers. Conclusions Specific search strategies based on adverse effects textwords and indexing terms will fail to identify nearly a quarter of trials that report on the rate of drug adverse effects.

On a PSG, central sleep apnea (central apnea-hypopnea index of 19/hour and nocturnal hypoventilation (transcutaneous CO2 > 50 mmHg for 53% of the night were found. A positive pressure initiation study was aborted because the patient developed a serious adverse reaction. The differential diagnosis included a skin fragility condition versus an allergic contact dermatitis to the interface; this could be from the povidone-iodine solution used to clean the NiPPV interface or from the plastic of the interface itself. A skin biopsy was performed which was normal. The reaction was likely secondary to an allergic contact dermatitis from the povidone-iodine solution used to clean the NiPPV interface. The patient is currently tolerating NiPPV.

    In various real-world applications, it is very useful mining unanticipated episodes where certain event patterns unexpectedly lead to outcomes, e.g., taking two medicines together sometimes causing an adverse reaction. These unanticipated episodes are usually unexpected and infrequent, which makes existing data mining techniques, mainly designed to find frequent patterns, ineffective. In this paper, we propose unexpected temporal association rules (UTARs) to describe them. To handle the unexpectedness, we introduce a new interestingness measure, residual-leverage, and develop a novel case-based exclusion technique for its calculation. Combining it with an event-oriented data preparation technique to handle the infrequency, we develop a new algorithm MUTARC to find pairwise UTARs. The MUTARC is applied to generate adverse drug reaction (ADR) signals from real-world healthcare administrative databases. It reliably shortlists not only six known ADRs, but also another ADR, flucloxacillin possibly causing hepatitis, which our algorithm designers and experiment runners have not known before the experiments. The MUTARC performs much more effectively than existing techniques. This paper clearly illustrates the great potential along the new direction of ADR signal generation from healthcare administrative databases.

    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.

    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.

    2008-10-01

    Full Text Available Abstract Background In recent years it has been found that the combination of evolutionary game theory with population structures modelled in terms of dynamical graphs, in which individuals are allowed to sever unwanted social ties while keeping the good ones, provides a viable solution to the conundrum of cooperation. It is well known that in reality individuals respond differently to disadvantageous interactions. Yet, the evolutionary mechanism determining the individuals' willingness to sever unfavourable ties remains unclear. Results We introduce a novel way of thinking about the joint evolution of cooperation and social contacts. The struggle for survival between cooperators and defectors leads to an arms race for swiftness in adjusting social ties, based purely on a self-regarding, individual judgement. Since defectors are never able to establish social ties under mutual agreement, they break adverse ties more rapidly than cooperators, who tend to evolve stable and long-term relations. Ironically, defectors' constant search for partners to exploit leads to heterogeneous networks that improve the survivability of cooperators, compared to the traditional homogenous population assumption. Conclusion When communities face the prisoner's dilemma, swift reaction to adverse ties evolves when competition is fierce between cooperators and defectors, providing an evolutionary basis for the necessity of individuals to adjust their social ties. Our results show how our innate resilience to change relates to mutual agreement between cooperators and how "loyalty" or persistent social ties bring along an evolutionary disadvantage, both from an individual and group perspective.

    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.

    Undetected adverse drug reactions (ADRs) pose a major burden on the health system. Data mining methodologies designed to identify signals of novel ADRs are of deep importance for drug safety surveillance. The development and evaluation of these methodologies requires proper reference benchmarks. While progress has recently been made in developing such benchmarks, our understanding of the performance characteristics of the data mining methodologies is limited because existing benchmarks do not support prospective performance evaluations. We address this shortcoming by providing a reference standard to support prospective performance evaluations. The reference standard was systematically curated from drug labeling revisions, such as new warnings, which were issued and communicated by the US Food and Drug Administration in 2013. The reference standard includes 62 positive test cases and 75 negative controls, and covers 44 drugs and 38 events. We provide usage guidance and empirical support for the reference standard by applying it to analyze two data sources commonly mined for drug safety surveillance.

  15. Adverse reactions to food constituents: allergy, intolerance, and autoimmunity.

    Food allergies and intolerance represent important health concerns to consumers who are predisposed to these illnesses. Unlike many current food safety issues, food sensitivities are complicated by both complex and multiple individual adverse reactions, which can vary from emotional to pathophysiological ailments. In some instances, the underlying mechanisms that result in the development of food allergies or intolerance have marked differences but produce common symptoms. The present-day diagnosis of these disorders can be impeded by intrinsic limitations in generating accurate information from patient history and biochemical, physicochemical, and immunochemical tests. Oral challenge tests represent effective methods for confirming and testing food allergens and food intolerance; however, these procedures are often restricted to clinical trials. It is important to be able to distinguish among food allergy, intolerance, and autoimmune disease in the management of these disorders. The role of food in the development of autoimmune disease may be exemplified by celiac disease, a food-induced enteropathy, requiring exposure to prolamins in wheat, rye, and barley. Various wheat and soy protein sources, including the soy protein isolates used to make infant formulas, have been related to juvenile or insulin-dependent diabetes mellitus (IDDM), a common chronic disease of childhood. Employing food process technologies to eliminate food constituents with potential for intolerance in some individuals is a potentially viable approach for reducing risk to food-related disorders. Finally, the development of food labelling regulations that require the identification of potential food allergens or agents for intolerance in the ingredient declaration on prepackaged food is a positive step toward the prevention of severe adverse reactions in hypersensitive individuals.

    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.

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.

    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.

    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.

    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. Moreover, it was irresponsibly promoted for the prevention of cardiovascular events, dementia, and as the source of eternal youth without proven efficacy at that time (no evidence of efficacy exist today.- Non-steroidal anti-inflammatory drugs (NSAIDs - especially celecoxib and diclofenac -increase the

    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.

  3. Feature Engineering for Recognizing Adverse Drug Reactions from Twitter Posts

    Full Text Available Social media platforms are emerging digital communication channels that provide an easy way for common people to share their health and medication experiences online. With more people discussing their health information online publicly, social media platforms present a rich source of information for exploring adverse drug reactions (ADRs. ADRs are major public health problems that result in deaths and hospitalizations of millions of people. Unfortunately, not all ADRs are identified before a drug is made available in the market. In this study, an ADR event monitoring system is developed which can recognize ADR mentions from a tweet and classify its assertion. We explored several entity recognition features, feature conjunctions, and feature selection and analyzed their characteristics and impacts on the recognition of ADRs, which have never been studied previously. The results demonstrate that the entity recognition performance for ADR can achieve an F-score of 0.562 on the PSB Social Media Mining shared task dataset, which outperforms the partial-matching-based method by 0.122. After feature selection, the F-score can be further improved by 0.026. This novel technique of text mining utilizing shared online social media data will open an array of opportunities for researchers to explore various health related issues.

    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.

    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.

    Abstract A systematic review of randomized controlled clinical trials of nonsteroidal antiinflammatory drugs (NSAIDs) in rheumatoid arthritis (RA) patients was conducted to evaluate the risk of NSAID-induced adverse reactions. Double-blind, randomized, controlled trials with 6-week treatments for RA patients were included in the study. The endpoints for the analysis included any adverse reactions, digestive adverse reactions, and upper gastrointestinal (GI) adverse reactions. A fixed-effect model was used for estimation of the risk. Time-to-event analysis of the incidence of adverse reactions was also conducted. A total of 28 trials was included for the analysis, and a total of 30 NSAIDs were used in the trials. The proportion of patients who experienced any adverse reaction was as follows: piroxicam 18.9% (3 trials), diclofenac 18.8% (4 trials), indomethacin 22.1% (14 trials), and aspirin 25.0% (4 trials). The proportion of patients who experienced digestive adverse reactions was as follows: piroxicam 10.2%, diclofenac 10.6%, indomethacin 13.1%, and aspirin 14.1%. Most withdrawals due to adverse reaction occurred during the first 3 weeks after administration of the NSAID. Although the risk of NSAID-induced adverse reaction was different from drug to drug, the risk of adverse reaction was clinically significant.

    To evaluate the incidence, severity, and risk factors of adverse drug reactions (ADR) to intravenous administration of nonionic iodinated contrast media in computed tomography (CT), and to determine the recurrence rate after premedication in patients with a previous history of ADR. We prospectively recorded all ADR to intravenous CT contrast media in 32313 consecutive outpatients (54572 cases) who underwent contrast enhanced CT examinations. Clinical report forms and electronic medical records were reviewed to search for the incidence of ADR, treatment, and clinical outcome of patients. The risk factors of ADR to CT contrast media (age, sex, history of previous ADR, season) were evaluated using statistical analysis. Of the 54572 cases, a total of 191 (0.35%) had adverse reactions. Of the 191 cases, 157 (82%) were categorized as mild reactions, 29 (15%) were moderate, and 5 (3%) were severe. A total of 165 (86.4%) cases had acute adverse reactions (which occurred within 1 hour after administration), while 26 (13.6%) had delayed adverse reactions (occurred 1 hour after the administration). The rate of ADR was significantly higher in females [relative risk (RR) = 2.05, 95% confidence interval (CI) 1.53-2.75], patients under the age of 60 years (RR = 1.45, 95% CI 1.07-1.98), patients with a history of previous ADR (RR = 6.51, 95% CI 3.13-13.57), and in the spring season (RR = 1.44, 95% CI 1.07-1.95). The recurrence rate after premedication in patients with previous ADR to CT contrast media was 3.2% (8/247). No deaths occurred that were attributed to the contrast media. The incidence of ADR to nonionic CT contrast media was 0.35%; most of which were mild reactions. Risk factors for ADR included female gender, an age of under 60 years, a history of previous ADR, and spring season.

    Natural health products are promoted to the public as equally or more effective and less toxic than conventional drugs. However, some 'natural' medicines are known to have adverse effects. From April 2002 to August 2007, 18 suspected adverse reactions associated with propolis-containing products were reported to the national surveillance system of natural health products, coordinated by the Italian National Health Institute. Sixteen reports concerned allergic reactions (with dermatological or respiratory symptoms), while two concerned the digestive tract. Some of the reactions were serious: six patients were admitted to hospital or visited an emergency department and in two of these a life-threatening event was reported. In seven patients (four of whom were children), an allergic predisposition was indicated. Propolis, a resinous substance collected by honeybees from the buds of living plants, has been used for several purposes (dermatitis, laryngitis, oral ulcers) because of its wide range of suggested activities (antibacterial, antiviral, antifungal, anti-inflammatory, antioxidant and chemopreventive actions). However, propolis is also a potent sensitizer and should not be used in patients with an allergic predisposition, in particular an allergy to pollen. In Italy, products containing bee derivatives (bee pollen, royal jelly or propolis) are available to the public as food supplements. No label warning of possible adverse reactions is found on the packaging, although it is well known that atopic and asthmatic individuals may be at an increased risk of allergic reactions after using these products. The public and healthcare practitioners should be aware of the risk of allergic reactions to products derived from bees and a warning should be added to the packaging of these products.

    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

    To determine the vaccination rate and its adverse reactions after influenza vaccination, we administered an anonymous questionnaire survey during the last three influenza seasons from 2005-2006 to 2007-2008. In total, the rate of Influenza vaccination was 82.3% in health-care personnel. Dividing the subjects into four groups by work category, the vaccine coverage rates were as follows: physicians 67.9%; nurses and nursing assistants 91.2%; technicians, pharmacists, therapists, and administrative personnel 80.2%; and other personnel not directly involved in patient care but having the potential of being exposed to infectious agents 89%. The most frequent adverse reaction after vaccination was soreness at the injection site in 33.4%, followed by skin redness in 18.1%, myalgia in 17.7%, fatigue in 17%, and febrile sensation in 15.2%. After vaccination, such adverse reactions began within 24 h in 70.6% of subjects. Eighty-nine percent of those adverse reactions persisted for 1-3 days, but 11% persisted more than 4 days. Serious adverse reactions were not noted; the reported adverse reactions were relatively minor and transient. Surprisingly, among those who were vaccinated, the physicians' participation was the lowest. We believe that influenza vaccination is safe and that physicians should be more concerned with influenza vaccination and its impact on the health-care community.

    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.

    Full Text Available Aim: To monitor and evaluate the pattern of ADRs to oseltamivir in pediatric population suffering from H1N1 influenza at a tertiary care hospital. Materials and Methods: Children offered oseltamivir for treatment and chemoprophylaxis were monitored for adverse events by direct questioning for symptoms and clinical examination on day 5 and day 10. Assessment of neurological events was done by asking the parents or guardians regarding development of specific symptoms. Adverse events obtained were analyzed for severity, causality and age-group wise. Results: Out of 191 children (median age, 3 years, 69 (36.1% developed ADRs. Most common symptoms were vomiting (16.2% followed by diarrhea (12.0%, ear disorders (8.9%, and insomnia (6.8%. The incidence of neuropsychiatric symptoms was 12.6% which were mild-to-moderate on severity scale. There was no significant difference in the incidence of adverse events between children less than 1 year and other age groups. Conclusion: Oseltamivir is well tolerated in Indian children with suspected or confirmed H1N1 influenza. Our study also indicates safety of oseltamivir in infants.

    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.

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.

    2015-06-01

    Full Text Available Recent alarming joint registry data highlighting increased revision rates has prompted further research into the area of metal-on-metal hip replacements and resurfacings. This review article examines the latest literature on the topic of adverse reactions to metal debris and summarises the most up-to-date guidelines on patient management. Adverse reactions to metal debris can cause significant damage to soft tissue and bone if not diagnosed early. Furthermore, not every patient with an adverse reaction to metal debris will be symptomatic. As such, clinicians must remain vigilant when assessing and investigating these patients in order to detect failing implants and initiate appropriate management.

    Conclusions: Cutaneous adverse drug reaction profile in this study is similar in many ways to studies conducted earlier in India. Incidence of life-threatening reactions like SJS-TEN was higher compared with studies conducted abroad. Reaction time and lesion patterns are helpful in identifying an offending drug in the setting of multiple drug therapy.

    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.

      The purpose of this study was to develop and validate estimate equations for preventing adverse drug reactions (ADRs). We conducted five case-control studies to identify individual risk factors and subjective symptoms associated with the following five ADRs: drug-induced ischemic heart disease; renal damage; muscle disorder; interstitial pneumonia; and leucopenia. We performed logistic regression analysis and obtained eight regression equations for each ADR. We converted these to ADR estimate equations for predicting the likelihood of ADRs. We randomly selected 50 cases with non-individual ADRs from the Case Reports of Adverse Drug Reactions and Poisoning Information System (CARPIS) database of over 65000 case reports of ADRs, and assigned these cases to a validation case group. We then calculated the predictive probability for 50 cases using the eight estimate equations for each ADR. The highest probability for each ADR was set as the probability of each ADR. If the probability was over 50%, the case was interpreted as ADR-positive. We calculated and evaluated the sensitivity, specificity, and positive likelihood ratio of this system. Sensitivity of the estimate equations for muscle disorder and interstitial pneumonia were ≥90%. Specificity and positive likelihood ratios of estimate equations for renal damage, interstitial pneumonia and leucopenia were ≥80% and ≥5, respectively. Our estimate equations thus showed high validity, and are therefore helpful for the prevention or early detection of ADRs.

    Background: Adverse drug reaction (ADR) is considered to be the sixth leading cause of death. The incidence rate estimates approximately 2% of hospital admissions are due to ADRs. Objective: To monitor ADRs in Pulmonology department of a tertiary care hospital patient with pulmonary diseases in an inpatient department of pulmonology. Materials and Methods: A prospective, single centered, observational and open labeled study was carried out in Princess Esra Hospital. The patient population was broadly divided into four categories based on diagnosis - chronic obstructive pulmonary disease, Infections, Asthma and Others. Suspected ADRs were reported, analyzed, and causality assessment was carried out using Naranjo's algorithm scale. Results: A total of 302 patients were observed, of which 98 patients experienced ADRs, which accounted for 32.23% of the incidence and totally 160 ADEs were observed. Adult Patients were found to have higher incidence (32.09%) while the incidence rate was slightly greater in geriatric patients (32.39%). The highest incidence of ADEs were found in others group (78.57%). Majority of ADRs were suspected to be due to theophylline (19.39%). Gastrointestinal system (38.75%) was the most common organ system affected due to ADRs. Drug was withdrawn in 12 patients, and specific treatment was administered to 32 patients in view of clinical status. Specific treatment for the management of suspected reaction was administered in 32.65% of ADR reports. Conclusion: A relatively high incidence of adverse drug events (32.2%) have been recorded which shows that not only Geriatric patients, but also adults are more susceptible to adverse drug effects. A number of drugs in combination were used, and ADEs often get multiplied. Careful therapeutic monitoring and dose individualization is necessary. PMID:26229344

    Purpose We investigated the appearance frequency of eyelid pigmentation and eyelash bristles after the use of five types of prostaglandin (PG) analogs. Methods This study included 250 eyes from 250 patients diagnosed with primary open-angle glaucoma or ocular hypertension who were treated with either latanoprost, travoprost, tafluprost, bimatoprost, or isopropyl unoprostone for >3 months in only one eye. Photographs of both eyes were obtained, and the images were assessed by three ophthalmologists who were masked to treatment type. The existence of eyelid pigmentation and eyelash bristles was judged, and images of the left and right eyes were compared. Subjective symptoms regarding the existence of eyelid pigmentation and eyelash bristles were investigated through a questionnaire. Results There was no significant difference between the five types of medications with regard to eyelid pigmentation (P=0.537). Use of isopropyl unoprostone resulted in a significantly lower incidence of eyelash bristles (P<0.0001). The questionnaire investigation showed that eyelid pigmentation and eyelash bristles were significantly more frequent with travoprost (42.0% and 42.0%, respectively) and bimatoprost (58.0% and 60.0%, respectively) than with other three medications (P<0.0001). Conclusion The appearance frequency of eyelid pigmentation was similar among the five types of PG analogs studied, and eyelash bristles appeared less frequently with isopropyl unoprostone use. Patients are conscious of eyelash bristles; therefore, these adverse effects should be sufficiently explained to patients before PG administration. PMID:23037910

    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.

    VIEKIRA PAK (ritonavir-boosted paritaprevir/ombitasvir and dasabuvir) is an approved treatment for compensated patients with genotype 1 (GT1) chronic hepatitis C virus (HCV) infection. This oral regimen has minimal adverse effects and is well tolerated. Cure rates are 97% in patients infected with HCV GT 1a and 99% in those with HCV GT 1b. We report the first case of life-threatening allergic pneumonitis associated with VIEKIRA PAK. This unexpected serious adverse event occurred in a 68-year-old Chinese female with genotype 1b chronic hepatitis C and Child-Pugh A cirrhosis. One week into treatment with VIEKIRA PAK without ribavirin, she was admitted to hospital with respiratory distress and acute kidney injury requiring intensive care input. She was initially diagnosed with community acquired pneumonia and improved promptly with intravenous antibiotics and supported care. No bacterial or viral pathogens were cultured. Following complete recovery, she recommenced VIEKIRA PAK but represented 5 days later with more rapidly progressive respiratory failure, requiring intubation and ventilation, inotropic support, and haemodialysis. The final diagnosis was drug induced pneumonitis.

    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.

  2. Perception of the risk of adverse reactions to analgesics: differences between medical students and residents

    2016-07-01

    Full Text Available Background. Medications are not exempt from adverse drug reactions (ADR and how the physician perceives the risk of prescription drugs could influence their availability to report ADR and their prescription behavior. Methods. We assess the perception of risk and the perception of ADR associated with COX2-Inbitors, paracetamol, NSAIDs, and morphine in medical students and residents of northeast of Mexico. Results. The analgesic with the highest risk perception in both group of students was morphine, while the drug with the least risk perceived was paracetamol. Addiction and gastrointestinal bleeding were the ADR with the highest score for morphine and NSAIDs respectively. Discussion. Our findings show that medical students give higher risk scores than residents toward risk due to analgesics. Continuing training and informing physicians about ADRs is necessary since the lack of training is known to induce inadequate use of drugs.

    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.

Of particular concern are the oldest old, which constitute an increasingly growing population. Having a validated clinical tool to identify those older patients at risk of developing an ADR during hospital stay would enable healthcare staff to put measures in place to reduce the risk of such an event developing. The current study aimed to (1 develop and (2 validate an ADR risk prediction model.We used a combination of univariate analysis and multivariate binary logistic regression to identify clinical risk factors for developing an ADR in a population of older people from a UK teaching hospital. The final ADR risk model was then validated in a European population (European dataset.Six-hundred-ninety patients (median age 85 years were enrolled in the development stage of the study. Ninety-five reports of ADR were confirmed by independent review in these patients.

    Background Older patients are at an increased risk of developing adverse drug reactions (ADR). Of particular concern are the oldest old, which constitute an increasingly growing population. Having a validated clinical tool to identify those older patients at risk of developing an ADR during hospital stay would enable healthcare staff to put measures in place to reduce the risk of such an event developing. The current study aimed to (1) develop and (2) validate an ADR risk prediction model. Methods We used a combination of univariate analysis and multivariate binary logistic regression to identify clinical risk factors for developing an ADR in a population of older people from a UK teaching hospital. The final ADR risk model was then validated in a European population (European dataset). Results Six-hundred-ninety patients (median age 85 years) were enrolled in the development stage of the study. Ninety-five reports of ADR were confirmed by independent review in these patients. Five clinical variables were identified through multivariate analysis and included in our final model; each variable was attributed a score of 1. Internal validation produced an AUROC of 0.74, a sensitivity of 80%, and specificity of 55%. During the external validation stage the AUROC was 0.73, with sensitivity and specificity values of 84% and 43% respectively. Conclusions We have developed and successfully validated a simple model to use ADR risk score in a population of patients with a median age of 85, i.e. the oldest old.

    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.

    Many think of an adverse drug reaction (ADR) as an adverse event caused by a medication intended for a given subject. However, as we learned from the thalidomide debacle 50 years ago, some of the most devastating ADRs affect not the subject who takes the medication but rather, in the case of pregnancy exposures, an innocent bystander--the fetus--and the ADRs include birth defects.

    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.

    2011-01-01

    Adverse drug reactions to trimethoprim-sulphonamide combinations are common in many species, manifesting as gastrointestinal tract disorders, dermatopathies and blood dyscrasias. In this case series, neurological abnormalities in 4 horses being treated with trimethoprim-sulphonamide combinations at normal dosages and in one foal that received an overdose are described. The horses developed hypermetric gait, agitation and erratic behaviour. All signs resolved once medication was withdrawn, and no horse had residual deficits. No other cause for observed neurological deficits could be determined. These clinical signs appear to represent a novel adverse drug reaction to some commonly used antimicrobial combinations.

    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.

  13. Prior adversities predict posttraumatic stress reactions in adolescents following the Oslo Terror events 2011

    Directory of Open Access Journals (Sweden)

    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.

    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.

    2016-11-01

    Full Text Available Purpose: To address the under-reporting of research results, with emphasis on the underreporting/distorted reporting of adverse events in the biomedical research literature. Design/methodology/approach: A four-step approach is used:(1 To identify the characteristics of literature that make it adequate to support policy; (2 to show how each of these characteristics becomes degraded to make inadequate literature; (3 to identify incentives to prevent inadequate literature; and (4 to show policy implications of inadequate literature. Findings: This review has provided reasons for, and examples of, adverse health effects of myriad substances (1 being under-reported in the premiere biomedical literature, or (2 entering this literature in distorted form. Since there is no way to gauge the extent of this under/distorted-reporting, the quality and credibility of the ‘premiere’ biomedical literature is unknown. Therefore, any types of meta-analyses or scientometric analyses of this literature will have unknown quality and credibility. The most sophisticated scientometric analysis cannot compensate for a highly flawed database. Research limitations: The main limitation is in identifying examples of under-reporting. There are many incentives for under-reporting and few dis-incentives. Practical implications: Almost all research publications, addressing causes of disease, treatments for disease, diagnoses for disease, scientometrics of disease and health issues, and other aspects of healthcare, build upon previous healthcare-related research published. Many researchers will not have laboratories or other capabilities to replicate or validate the published research, and depend almost completely on the integrity of this literature. If the literature is distorted, then future research can be misguided, and health policy recommendations can be ineffective or worse. Originality/value: This review has examined a much wider range of technical and nontechnical

    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.

    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.

    This report summarises Australian passive surveillance data for adverse events following immunisation (AEFI) for 2014 reported to the Therapeutic Goods Administration for 2014 and describes reporting trends over the 15-year period 1 January 2000 to 31 December 2014. There were 3,087 AEFI records for vaccines administered in 2014; an annual AEFI reporting rate of 13.2 per 100,000 population. There was a decline of 5% in the overall AEFI reporting rate in 2014 compared with 2013. This decline in reported adverse events in 2014 compared with the previous year was mainly attributable to fewer reports following the human papillomavirus (HPV) vaccine as it was the 2nd year of the extension of the National HPV Vaccination Program to males. AEFI reporting rates for most vaccines were lower in 2014 compared with 2013. The most commonly reported reactions were injection site reaction (27%), pyrexia (18%), rash (16%), vomiting (9%), headache (7%), and syncope (5%). The majority of AEFI reports described non-serious events while 7% (n=211) were classified as serious. There were 5 deaths reported with no clear causal relationship with vaccination found.

    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.

    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.

    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.

Materials and Methods: All serious ADRs reported from January 2010 to May 2015 at ADR Monitoring Centre, Department of Pharmacology, B. J. Medical College and Civil Hospital, Ahmedabad, were selected as per the World health Organization -Uppsala Monitoring Center (WHO-UMC criteria. A retrospective analysis was carried out for clinical presentation, causality (as per the WHO-UMC scale and Naranjo′s algorithm, severity (Hartwig and Siegel scale, and preventability (Schumock and Thornton criteria. Results: Out of 2977 ADRs reported, 375 were serious in nature. The most common clinical presentation involved was skin and appendageal disorders (71, 18.9%. The common causal drug group was antitubercular (129, 34.4% followed by antiretroviral (76, 20.3% agents. The criteria for the majority of serious ADRs were intervention to prevent permanent impairment or damage (164, 43.7% followed by hospitalization (158, 42.1%. Majority of the serious ADRs were continuing (191, 50.9% at the time of reporting, few recovered (101, 26.9%, and two were fatal. The majority of serious ADRs were categorized as possible (182, 48.8% followed by probable (173, 46.1% in nature. Conclusion: Antitubercular, antiretroviral, and antimicrobial drugs were the most common causal drug groups for serious ADRs. This calls for robust ADR monitoring system and education of patients and prescribers for identification and effective management.

    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.

    Passive reporting of adverse events following immunization (AEFI) by consumers or healthcare professionals is the primary mechanism for post-marketing surveillance of vaccine safety. Although recent initiatives have promoted consumer reporting, there is a lack of research concerning consumer reporters. Computer assisted telephone interviews (CATI) were conducted in 2011 of a cross-sectional, random, general population sample of 191 South Australian parents who stated that their children had previously experienced an AEFI. We compared awareness of surveillance, vaccine safety opinions, and demographics of parents reporting an AEFI to either healthcare professionals or surveillance authorities with those who did not report their children's AEFI. Multivariate regression analyses measured: the association between reporting and safety views; and demographic predictors of reporting an AEFI. Reporting an AEFI to a healthcare professional or a surveillance authority was not significantly associated with awareness of a surveillance system. AEFI reporters, when compared with non-reporters, were more likely to be Australian-born (OR = 4.58, [1.64, 12.78], P = 0.004); were associated with the perception that a serious reaction was more likely to occur at their children's last immunization (OR = 2.54 [95%CI 1.22, 5.30], P = 0.013); and were less accepting of the risk of febrile convulsion, (OR = 3.59 [95%CI 1.50, 8.57], P = 0.004). Although reporting an AEFI was not associated with awareness of surveillance or most socio-demographics, the results suggest some difference in safety opinions. Further studies are required to ascertain if these differences pre-date the occurrence of an AEFI or are a consequence of the AEFI and how consumers can contribute further to vaccine safety surveillance.

    The elderly are one of the groups at greatest risk for adverse drugs reactions (ADR). The mean prevalence of these reactions in this population is 30%. Dementia is not an independent risk factor of ADR, but is the main condition that increases all risk factors (polypharmacy, comorbidity, inappropriate prescribing, drug-drug interactions, advanced age, and treatment adherence). The present article discusses revised and consensual recommendations for the prevention of ADR in the elderly, as well as recommendations specifically for dementia patients in relation to the management of comorbidity and cognitive, behavioral and psychological symptoms.

    Full Text Available Thousands of samples for pharmacogenetic tests have been analysed in our laboratory since its establishment. In this article we describe some of the most interesting cases of CYP poor metabolisers associated with adverse reactions to psychotropic drugs. Prevention of disease/illness, including Adverse Drug Reaction (ADR, is an aim of modern medicine. Scientific data supports the fact that evaluation of drug toxicology includes several factors, one of which is genetic variations in pharmacodynamics and pharmacokinetics of drug pathways. These variations are only a part of toxicity evaluation, however, even if it would help to prevent only a small percentage of patients from suffering adverse drug reactions, especially life threatening ADRs, pharmacogenetic testing should play a significant role in any modern psychopharmacologic practice. Medical practitioners should also consider the use of other medications or alternative dosing strategies for drugs in patients identified as altered metabolisers. This will promise not only better and safer treatments for patients, but also potentially lowering overall healthcare costs.

    Background and Purpose. Contrast media (CM) for magnetic resonance imaging (MRI) may determine the development of acute adverse reactions. Objective was to retrospectively assess the frequency and severity of adverse reactions associated with gadolinium-based contrast agents (GBCAs) injection in patients who underwent MRI. Material and Methods. At our center 10608 MRI examinations with CM were performed using five different GBCAs: Gd-BOPTA (MultiHance), Gd-DTPA (Magnevist), Gd-EOBDTPA (Primovist), Gd-DOTA (Dotarem), and Gd-BTDO3A (Gadovist). Results. 32 acute adverse reactions occurred, accounting for 0.3% of all administration. Twelve reactions were associated with Gd-DOTA injection (0.11%), 9 with Gd-BOPTA injection (0.08%), 6 with Gd-BTDO3A (0.056%), 3 with Gd-EOB-DTPA (0.028%), and 2 with Gd-DTPA (0.018%). Twenty-four reactions (75.0%) were mild, four (12.5%) moderate, and four (12.5%) severe. The most severe reactions were seen associated with use of Gd-BOPTA, with 3 severe reactions in 32 total reactions. Conclusion. Acute adverse reactions are generally rare with the overall adverse reaction rate of 0.3%. The most common adverse reactions were not severe, consisting in skin rash and hives. PMID:27652261

    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.

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

    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.

    The difficult task of detecting adverse drug events (ADEs) and the tedious process of building manual reports of ADE occurrences out of patient profiles result in a majority of adverse reactions not being reported to health regulatory authorities. The SALUS individual case safety report (ICSR) reporting tool, a component currently developed within the SALUS project, aims to support semi-automatic reporting of ADEs to regulatory authorities. In this paper, we present an initial design and current state of of our ICSR reporting tool that features: (i) automatic pre-population of reporting forms through extraction of the patient data contained in an Electronic Health Record (EHR); (ii) generation and electronic submission of the completed ICSRs by the physician to regulatory authorities; and (iii) integration of the reporting process into the physician's work-flow to limit the disturbance. The objective is to increase the rates of ADE reporting and the quality of the reported data. The SALUS interoperability platform supports patient data extraction independently of the EHR data model in use and allows generation of reports using the format expected by regulatory authorities.

    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.

    The first remarkable adverse drug reaction (ADR) reported in Japan was anaphylactic shock caused by penicillin. Although intradermal testing for antibiotics had been exercised as prediction method of anaphylactic shock for a long time, it was discontinued in 2004 because of no evidence for prediction. The malformation of limbs, etc. caused by thalidomide was a global problem, and thalidomide was withdrawn from the market. Teratogenicity testing during new drug development has been implemented since 1963. Chinoform (clioquinol)-iron chelate was detected from green tongue and green urine in patients with subacute myelo-optic neuropathy (SMON) and identified as a causal material of SMON in 1970. Chinoform was withdrawn from the market, and a fund for relief the health damage caused by ADR was established in 1979. The co-administration of sorivudine and fluorouracil anticancer agents induced fatal agranulocytosis, and sorivudine was withdrawn from the market after being on sale for one month in 1993. The guidelines for package inserts were corrected with this opportunity, and early phase pharmacovigilance of new drugs was introduced later. Since acquired immune deficiency syndrome, and hepatitis B and C were driven by virus-infected blood products, the Ministry of Health, Labor and Welfare tightened regulations regarding biological products in 2003, and a fund for relief of health damage caused by infections driven from biological products was established in 2004. The other remarkable ADRs were quadriceps contracture induced by the repeated administration of muscular injection products and Creutzfeldt-Jakob disease caused by the transplantation of human dry cranial dura matter, etc. The significance of safety measures for drugs based on experiences related to ADRs is worthy of notice. New drugs are approved based on a benefit-risk assessment, if the expected therapeutic benefits outweigh the possible risks associated with treatment. Since unexpected, rare and serious

    Full Text Available Background: Potentially inappropriate medication (PIM use in the elderly is associated with increased risk of adverse drug reactions (ADRs, but there is limited information regarding PIM use in the intensive care unit (ICU setting. Objective: The aim of the study is to describe the prevalence and factors associated with the use of PIM and the occurrence of PIM-related adverse reactions in the critically ill elderly. Methods: This study enrolled all critically ill older adults (60 years or more admitted to medical or cardiovascular ICUs between January and December 2013, in a large tertiary teaching hospital. For all patients, clinical pharmacists listed the medications given during the ICU stay and data on drugs were analyzed using 2012 Beers Criteria, to identify the prevalence of PIM. For each identified PIM the medical records were analyzed to evaluate factors associated with its use. The frequency of ADRs and, the causal relationship between PIM and the ADRs identified were also evaluated through review of medical records. Results: According to 2012 Beers Criteria, 98.2% of elderly patients used at least one PIM (n=599, of which 24.8% were newly started in the ICUs. In 29.6% of PIMs, there was a clinical circumstance that justified their prescription. The number of PIMs was associated with ICU length of stay and total number of medications. There was at least one ADR identified in 17.8% of patients; more than 40% were attributed to PIM, but there was no statistical association. Conclusions: There is a high prevalence of PIM used in acutely ill older people, but they do not seem to be the major cause of adverse drug reactions in this population. Although many PIMs had a clinical circumstance that led to their prescription during the course of ICU hospitalization, many were still present upon hospital discharge. Therefore, prescription of PIMs should be minimized to improve the safety of elderly patients.

    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.

    Adverse drug reactions associated with the use of anticancer drugs are a worldwide problem and cannot be ignored. Adverse drug reactions can range from nausea, vomiting or any other mild reaction to severe myelosuppression. The study was planned to observe the suspected adverse drug reactions of cancer chemotherapy in patients aged >18 years having cancer attending Postgraduate Institute of Medical Education and Research, Chandigarh. During the study period, 101 patients of breast cancer and 73 patients of lung cancer were screened for occurrence of adverse drug reactions during their treatment with chemotherapy. About 87.36% patients experienced adverse drug reactions, 90.09% and 83.56% of breast and lung cancer patients experienced at least one adverse drug reaction respectively. In breast cancer patients, 41.58% patients were prescribed fluorouracil+doxorubicin+cyclophosphamide while paclitaxel was prescribed to 22.77% patients. Alopecia (54.94%), nail discolouration (43.96%), dysgeusia (38.46%), anorexia (30.77%), nausea (29.67%), and neuropathy (29.67%) were found to be very common in breast cancer patients treated with single/combined regimen. In lung cancer group of patients, cisplatin with docetaxel, cisplatin with pemetrexed and cisplatin with irinotecan were prescribed to 30.14, 24.65 and 17.81% patients, respectively. Dysgeusia (40.98%), diarrhoea (39.34%), anorexia (32.77%) and constipation (31.15%) and alopecia (31.15%) were commonly observed adverse drug reactions having lung cancer patients. Causality assessments using World Health Organization causality assessment scale showed that observed adverse drug reactions were of probable (64.67%) and possible (35.33%) categories.

    Full Text Available An adverse drug reaction (ADR is a serious concern for practicing veterinarians and other health professionals, and refers to an unintended, undesired and unexpected response to a drug that negatively affects the patient's health. It may be iatrogenic or genetically induced, and may result in death of the affected animal. The ADRs are often complicated and unexpected due to myriad clinical symptoms and multiple mechanisms of drug-host interaction. Toxicity due to commonly used drugs is not uncommon when they are used injudiciously or for a prolonged period. Licosamides, exclusively prescribed against anaerobic pyoderma, often ends with diarrhoea and vomiting in canines. Treatment with Penicillin and β-lactam antibiotics induces onset of pemphigious vulgare, drug allergy or hypersensitivity. Chloroamphenicol and aminoglycosides causes Gray's baby syndrome and ototoxicity in puppies, respectively. Aminoglycosides are very often associated with nephrotoxicity, ototoxicity and neuromuscular blockage. Injudicious use of fluroquinones induces the onset of arthropathy in pups at the weight bearing joints. The most effective therapeutic measure in managing ADR is to treat the causative mediators, followed by supportive and symptomatic treatment. So, in this prospective review, we attempt to bring forth the commonly occurring adverse drug reactions, their classification, underlying mechanism, epidemiology, treatment and management as gleaned from the literature available till date and the different clinical cases observed by the authors.

    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.

    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.

    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.

    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.

    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.

    Paolo Pellegrino

    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 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.

    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.

    The aim of the study was to investigate whether adverse drug reactions (ADRs) during immunotherapy with a grass extract (AVANZ® Phleum, ALK-Abelló) are related to the different patterns of sensitization of patients to grass allergens. A total of 192 patients with rhinitis and/or asthma sensitized to grass pollen received a 4-week updosing with five injections. ADRs were evaluated following EAACI guidelines. A total of 432 ADRs in 133 (69%) patients were recorded, 64% local and 31% systemic. There was a significant association between the number of grass allergens that sensitized the patients and the total number of ADRs (P = 0.004) occurred locally (P = 0.003) and systemically (P = 0.01). Sensitization to Phl p1 + Phl p5 or Phl p1 + Phl p5 + Phl p12 was significantly associated with a higher frequency of local or systemic reactions (P = 0.001, both). Different patterns of sensitization to grass allergens may potentially be considered a risk marker to the development of ADRs to immunotherapy.

    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 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

    Full Text Available Nibu Parameswaran Nair, Leanne Chalmers, Gregory M Peterson, Bonnie J Bereznicki, Ronald L Castelino, Luke R Bereznicki Division of Pharmacy, School of Medicine, Faculty of Health, University of Tasmania, Hobart, TAS, Australia Abstract: 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.

    Full Text Available Background: Cutaneous adverse drug reactions (CADRs may either be immunological or non-immunological. The precise mechanisms, however, are largely obscure. Other concomitant mechanisms may amplify and/or contribute to the severity and duration of a reaction. One such mechanism could be oxidative stress, a state of imbalance between reactive oxygen species, and their subsequent detoxification by antioxidants. Aims: (a to assess the oxidative stress status in the blood of cutaneous drug reaction patients by assaying for reduced glutathione (GSH and malondialdehyde (MDA levels, (b to determine the leukocyte migration inhibition (LMI response in these patients in response to the suspected drug (s, and (c to look for the association between oxidative stress parameters and LMI. Methods: Ethical committee approval was obtained for this study. Fresh venous blood samples were obtained from the patients of CADRs (group A during the acute phase of reaction and healthy control subjects (group B. MDA levels, a measure of oxidative lipid damage, and reduced GSH levels, a measure of anti-oxidant capacity, were assayed in the blood samples of both groups using spectrophotometry. LMI response was measured by challenging the patients′ peripheral blood mononuclear cells with the suspected drug to confirm immunological perturbation. Results: Totally 66 participants, 33 cases in group A and equal number of controls in group B, were studied. The mean MDA levels were found to be raised (P < 0.001, but GSH levels were significantly reduced in group A when compared with group B (P = <0.001. LMI response against drug(s was performed in 33 cases (group A, out of which 25 cases showed a positive LMI response as follows: fixed drug eruption (10/25, SJS (5/25, urticaria (3/25, exfoliative dermatitis (2/25, morbilliform rash (2/25, erythroderma (1/25, vasculitis (1/25, and dapsone syndrome (1/25.

    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.

    Adverse drug reactions (ADRs) represent the first cause of change of the first-line highly active antiretroviral therapy (HAART) regimen, therefore, they constitute the main limiting factor in the long-term follow up of HIV patients in treatment. A retrospective study was carried out in a specialized center in Lara State, Venezuela, including 99 patients over 18 years of age who had change of first-line HAART regimen due to ADRs, between 2010 and 2013. The aims of this research were to describe the sociodemographic and clinical variables, frequency of ADRs related to change of HAART, duration of the first-line HAART regimen, to determine the drugs associated with ARVs and to identify the risk factors. The ADRs constituted 47.5% of all causes of change of first-line HAART regimen, the median duration was 1.08±0.28 years. The most frequent ADRs were anemia (34.3%), hypersensitivity reactions (20.2%) and gastrointestinal intolerance (13.1%). The most frequent ARV regimen type was the protease inhibitors-based regimen (59.6%), but zidovudine was the ARV most linked to ADRs (41.4%). The regression analysis showed increased risk of ADRs in singles and students in the univariate analysis and heterosexuals and homosexuals in multivariate analysis; and decreased risk in active workers. The present work shows the high prevalence of ADRs in the studied population and represents the first case-based study that describes the pharmacoepidemiology of a cohort of HIV-positive patients treated in Venezuela.

    Full Text Available ABSTRACT Objective: to identify and summarize studies examining both drug-drug interactions (DDI and adverse drug reactions (ADR in older adults polymedicated. Methods: an integrative review of studies published from January 2008 to December 2013, according to inclusion and exclusion criteria, in MEDLINE and EMBASE electronic databases were performed. Results: forty-seven full-text studies including 14,624,492 older adults (≥ 60 years were analyzed: 24 (51.1% concerning ADR, 14 (29.8% DDI, and 9 studies (19.1% investigating both DDI and ADR. We found a variety of methodological designs. The reviewed studies reinforced that polypharmacy is a multifactorial process, and predictors and inappropriate prescribing are associated with negative health outcomes, as increasing the frequency and types of ADRs and DDIs involving different drug classes, moreover, some studies show the most successful interventions to optimize prescribing. Conclusions: DDI and ADR among older adults continue to be a significant issue in the worldwide. The findings from the studies included in this integrative review, added to the previous reviews, can contribute to the improvement of advanced practices in geriatric nursing, to promote the safety of older patients in polypharmacy. However, more research is needed to elucidate gaps.

    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.

    2011-07-01

    Adverse drug reactions (ADRs) can have severe consequences, and therefore the ability to predict ADRs prior to market introduction of a drug is desirable. Computational approaches applied to preclinical data could be one way to inform drug labeling and marketing with respect to potential ADRs. Based on the premise that some of the molecular actors of ADRs involve interactions that are detectable in large, and increasingly public, compound screening campaigns, we generated logistic regression models that correlate postmarketing ADRs with screening data from the PubChem BioAssay database. These models analyze ADRs at the level of organ systems, using the system organ classes (SOCs). Of the 19 SOCs under consideration, nine were found to be significantly correlated with preclinical screening data. With regard to six of the eight established drugs for which we could retropredict SOC-specific ADRs, prior knowledge was found that supports these predictions. We conclude this paper by predicting that SOC-specific ADRs will be associated with three unapproved or recently introduced drugs.

    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.

    Although MedDRA has obvious advantages over previous terminologies for coding adverse drug reactions and discovering potential signals using data mining techniques, its terminological organization constrains users to search terms according to predefined categories. Adding formal definitions to MedDRA would allow retrieval of terms according to a case definition that may correspond to novel categories that are not currently available in the terminology. To achieve semantic reasoning with MedDRA, we have associated formal definitions to MedDRA terms in an OWL file named OntoADR that is the result of our first step for providing an "ontologized" version of MedDRA. MedDRA five-levels original hierarchy was converted into a subsumption tree and formal definitions of MedDRA terms were designed using several methods: mappings to SNOMED-CT, semi-automatic definition algorithms or a fully manual way. This article presents the main steps of OntoADR conception process, its structure and content, and discusses problems and limits raised by this attempt to "ontologize" MedDRA.

    In this survey, the correlation between adverse drug reactions (ADRs) in human and animal toxicities was investigated for 393 medicines which were approved in Japan from September 1999 to March 2013. ADRs were collected from each Japanese package insert. Comparable animal toxicities with ADRs were collected by thorough investigation of common technical documents. The results of this survey show that hypertension and/or hypotension were mainly observed in medicines affecting the central nervous system. Hypertension was also observed in antipyretics, analgesics, anti-inflammatory agents, vasoconstrictors and agents using antibody. Concordance between human ADRs and animal toxicities was analysed. True-positive rate for hypertension and hypotension is 0.29 and 0.52, respectively. Positive likelihood ratio and inverse negative likelihood ratio are 1.98 and 1.21, respectively, in hypertension and 1.67 and 1.44, respectively, in hypotension. Concordance between human ADRs and animal toxicities is not so high in hypertension and hypotension. Identified mechanisms as on-target for hypertension and hypotension are 29.8% and 30.5%, respectively. More than half of the causative factors of hypertension and hypotension were unable to be elucidated. Our results show that the intake of medicines is often linked to blood pressure variations that are not predicted in animal toxicity studies. Improvement of drug development processes may be necessary to provide safer medicines because current animal toxicity studies are insufficient to predict all ADRs in human beings.

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

    Full Text Available A large proportion of the population all over the world consumes acetylsalicylic acid (ASA: aspirin or other nonsteroidal, antiinflammatory drugs (NSAIDs. This is associated with a considerable morbidity and mortality. Elderly patients, patients with prior history of peptic ulcer disease (PUD or its complications, those who require high doses of NSAIDs and those undergoing concomitant therapy with corticosteroids or anticoagulants, are at particularly high risk of developing gastroduodenal injuries and related adverse reactions. Gastroduodenal mucosal injuries induced by NSAIDs vary from subtle microscopic to gross macroscopic changes including ulcers. These injuries are induced by both topical and systemic actions of NSAIDs. Inhibition of gastroduodenal cyclooxygenase (COX enzyme by NSAIDs is considered to be a major pathogenetic factor. Reactive oxygen species (ROS appear also to play a significant role in the pathogenesis of mucosal injury. Withdrawal of NSAIDs is preferably the first therapeutic option; however, it is not feasible in the majority of patients. Therefore, several drugs including antisecretory drugs (ASDs-proton pump inhibitors and Histamine-2 receptor antagonists and misoprostol, a prostaglandin analog are used for the prevention and treatment of NSAID-induced gastroduodenal injuries. Among ASDs, proton pump inhibitors (PPIs are the most commonly used drugs. The antiulcerogenic effect of PPIs is similar to that of misoprostol and superior to standard doses of histamine-2 receptor antagonists (H2-RAs. The adverse effects of m,isoprostol such as diarrhea, abdominal pain, nausea, flatulence, headache, dyspepsia, vomiting, constipation, abortifacient and teratogenicity limit its general use. Aside from their antisecretory action, PPIs also possess an antioxidative effect. PPI maintenance is recommended in chronic NSAID treatment in those with an increased risk of complications and is more effective than Helicobacter pylori

    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

    It has been reported that the response rate to TS-1 of advanced recurrent gastric cancer was the highest rate (46.5%) of effectiveness among anti-cancer agents, but the incidence of adverse reactions to this drug has been found to be as high as 83.2%, with grade 3 or severer reactions occurring in 20.3% of patients. Taking into consideration the post-marketing survey finding that adverse reactions to the drug first appear 2-3 weeks after the start of oral TS-1 therapy, we attempted a new dosing regimen for this drug, wherein each session of therapy lasted for 2 weeks, with a one-week interval between two consecutive sessions (herein-after called "the 2-week regimen"). This regimen was employed based on the expectation that the adverse reactions to the drug would be minimized and that the consecutive dosing period could be prolonged, while keeping the anti-cancer potency at a level similar to that expected with the 4-week dosing regimen with a 2-week interval between sessions (the 4-week regimen). The subjects were 38 patients with advanced or recurrent stomach cancer who were treated with TS-1 at our center between September 1999 and November 2001. Twenty-four patients treated using the 4-week method until January 2001 were taken as a historical control, and compared with 14 patients treated using the 2-week method from February 2001 and afterwards. The incidence of adverse reactions was 71% in the 2-week regimen group against 92% in the 4-week regimen group. The incidence of grade 3 or severe adverse reactions was 8% in the 2-week group and 21% in the 4-week group. Thus, the incidence of adverse reactions was lower in the 2-week group. The percentage of patients who complied with the dosing instructions completely during a 6-month period, as evaluated by the Kaplan-Meier method, was 86% in the 2-week group and 58% in the 4-week group. The response rate, as calculated in patients whose lesions could be evaluated, was 25% in the 2-week group and 19% in the 4-week

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.

    Full Text Available CONTEXT AND OBJECTIVES: Adverse drug reactions (ADRs may cause prolonged hospital admissions with high treatment costs. The burden of ADRs in children has never been evaluated in Nigeria. The incidence of pediatric ADRs and the estimated cost of treatment over an 18-month period were determined in this study. DESIGN AND SETTING: Prospective observational study on children admitted to the pediatric wards of the Lagos State University Teaching Hospital (LASUTH in Nigeria, between July 2006 and December 2007. METHODS: Each patient was assessed for ADRs throughout admission. Medical and non-medical costs to the hospital and patient were estimated for each ADR by reviewing the medical and pharmacy bills, medical charts and diagnostic request forms and by interviewing the parents. Cost estimates were performed in 2007 naira (Nigeria currency from the perspectives of the hospital (government, service users (patients and society (bearers of the total costs attributable to treating ADRs. The total estimated cost was expressed in 2007 United States dollars (USD. RESULTS: Two thousand and four children were admitted during the study; 12 (0.6% were admitted because of ADRs and 23 (1.2% developed ADR(s during admission. Forty ADRs were suspected in these 35 patients and involved 53 medicines. Antibiotics (50% were the most suspected medicines. Approximately 1.83 million naira (USD 15,466.60 was expended to manage all the patients admitted due to ADRs. CONCLUSIONS: Treating pediatric ADRs was very expensive. Pediatric drug use policies in Nigeria need to be reviewed so as to discourage self-medication, polypharmacy prescription and sales of prescription medicines without prescription.

    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.

    The objective of the present study was to determine the frequency of adverse drug reactions (ADRs) in intensive care units (ICUs) and to evaluate their effect on the length of stay. We performed a prospective study to detect ADRs in 420 patients hospitalised in 10 predetermined beds in the ICU of our hospital between the months of March and December 1996. While the patients were staying in the ICU, data was gathered regarding suspected ADRs and on different variables related to the length of stay. 96 different ADRs were detected in 85 of the 420 patients seen [20.2%, 95% confidence intervals (95% CI) 16.5 to 24.4]. The ADRs were most frequently caused by the following drugs: nitrates (n = 25), opiates (n = 21) and ultrashort-acting benzodiazepines (n = 10). Eight ADRs were severe, the suspected medication had to be discontinued in 51 cases and new drugs were necessary to manage the ADRs in 73 cases. The crude estimation of the effect of the number of ADRs performed with a bivariant regression model indicated that each ADR was related to a 2.38-day increase (95% CI 1.31 to 3.45) in the length of stay. Although this estimation was reduced to 1.76 days (95% CI 0.72 to 2.79), when other confounding variables associated with the length of stay were considered, it was still important.In conclusion, the ADRs were a significant clinical problem in the ICUs and were responsible for a significant increase in the length of stay.

  11. Harvesting candidate genes responsible for serious adverse drug reactions from a chemical-protein interactome.

    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.

    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.

    Golder, Su; Wright, Kath

    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

    2011-03-01

    We report three cases of anaphylaxis during anaesthesia confirmed on intradermal testing to be related to patent blue V dye (Guerbet - Chemical Abstract Service 3536-49-0). All three cases were associated with moderate to severe hypotension. Two cases had delayed onset, and two were associated with a rash. None of the cases were associated with bronchospasm. In all three patients the interference with pulse oximetry readings contributed to difficulties in management. We recommend the use of a test dose of blue dye prior to surgery, as suggested in the manufacturer's product information. We also recommend high vigilance for possible allergic reactions when patent blue dyes are used for sentinel lymph node mapping, because the presentations may be atypical and the reduced pulse oximetry readings may be a distraction.

  1. A potential causal association mining algorithm for screening adverse drug reactions in postmarketing surveillance.

    Early detection of unknown adverse drug reactions (ADRs) in postmarketing surveillance saves lives and prevents harmful consequences. We propose a novel data mining approach to signaling potential ADRs from electronic health databases. More specifically, we introduce potential causal association rules (PCARs) to represent the potential causal relationship between a drug and ICD-9 (CDC. (2010). International Classification of Diseases, Ninth Revision (ICD-9). [Online]. Available: http://www.cdc.gov/nchs/icd/icd9.html) coded signs or symptoms representing potential ADRs. Due to the infrequent nature of ADRs, the existing frequency-based data mining methods cannot effectively discover PCARs. We introduce a new interestingness measure, potential causal leverage, to quantify the degree of association of a PCAR. This measure is based on the computational, experience-based fuzzy recognition-primed decision (RPD) model that we developed previously (Y. Ji, R. M. Massanari, J. Ager, J. Yen, R. E. Miller, and H. Ying, "A fuzzy logic-based computational recognition-primed decision model," Inf. Sci., vol. 177, pp. 4338-4353, 2007) on the basis of the well-known, psychology-originated qualitative RPD model (G. A. Klein, "A recognition-primed decision making model of rapid decision making," in Decision Making in Action: Models and Methods, 1993, pp. 138-147). The potential causal leverage assesses the strength of the association of a drug-symptom pair given a collection of patient cases. To test our data mining approach, we retrieved electronic medical data for 16,206 patients treated by one or more than eight drugs of our interest at the Veterans Affairs Medical Center in Detroit between 2007 and 2009. We selected enalapril as the target drug for this ADR signal generation study. We used our algorithm to preliminarily evaluate the associations between enalapril and all the ICD-9 codes associated with it. The experimental results indicate that our approach has a potential to

    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

    TS-1 is an oral anti-cancer agent for gastric cancer with a high response rate and low toxicity. We report a case of long-term drug retention of TS-1 causing interstitial lung disease (ILD) as a fatal adverse reaction. A 65-year-old woman underwent a total gastrectomy with pathologic confirmation of gastric adenocarcinoma. She received 6 cycles of TS-1 and low-dose cisplatin for post-operative adjuvant chemotherapy followed by single-agent maintenance therapy with TS-1. After 8 months, the patient complained of a productive cough with sputum and mild dyspnea. A pulmonary evaluation revealed diffuse ILD in the lung fields, bilaterally. In spite of discontinuing chemotherapy and the administration of corticosteroids, the pulmonary symptoms did not improve, and the patient died of pulmonary failure. TS-1-induced ILD can be caused by long-term drug retention that alters the lung parenchyma irreversibly, the outcome of which can be life-threatening. Pulmonary evaluation for early detection of disease is recommended.

    It has been 12 years since the Allele Frequency Net Database (AFND; http://www.allelefrequencies.net) was first launched, providing the scientific community with an online repository for the storage of immune gene frequencies in different populations across the world. There have been a significant number of improvements from the first version, making AFND a primary resource for many clinical and scientific areas including histocompatibility, immunogenetics, pharmacogenetics and anthropology studies, among many others. The most widely used part of AFND stores population frequency data (alleles, genes or haplotypes) related to human leukocyte antigens (HLA), killer-cell immunoglobulin-like receptors (KIR), major histocompatibility complex class I chain-related genes (MIC) and a number of cytokine gene polymorphisms. AFND now contains >1400 populations from more than 10 million healthy individuals. Here, we report how the main features of AFND have been updated to include a new section on 'HLA epitope' frequencies in populations, a new section capturing the results of studies identifying HLA associations with adverse drug reactions (ADRs) and one for the examination of infectious and autoimmune diseases associated with KIR polymorphisms-thus extending AFND to serve a new user base in these growing areas of research. New criteria on data quality have also been included.

    Canine non-rabies combined vaccines are widely used to protect animals from infectious agents, and also play an important role in public health. We performed a large-scale survey to investigate vaccine-associated adverse events (VAAEs), including anaphylaxis, in Japan by distributing questionnaires on VAAEs to veterinary hospitals from April 1, 2006 through May 31, 2007. Valid responses were obtained for 57,300 vaccinated dogs at 573 animal hospitals; we obtained VAAEs information for last 100 vaccinated dogs in each veterinary hospital. We found that of the 57,300, 359 dogs showed VAAEs. Of the 359 dogs, death was observed in 1, anaphylaxis in 41, dermatological signs in 244, gastrointestinal signs in 160, and other signs in 106. Onset of VAAEs was mostly observed within 12h after vaccination (n=299, 83.3%). In this study, anaphylaxis events occurred within 60 min after vaccination, and about half of these events occurred within 5 min (n=19, 46.3%). Furthermore, where anaphylaxis was reported, additional information to support the diagnosis was obtained by reinvestigation. Our resurvey of dogs with anaphylaxis yielded responses on 31 dogs; 27 of these demonstrated collapse (87.1%), 24 demonstrated cyanosis (77.4%), and both signs occurred in 22 (71.0%). Higher rates of animal VAAEs, anaphylaxis, and death were found in Japan than in other countries. Further investigations, including survey studies, will be necessary to elucidate the interaction between death and vaccination and the risk factors for VAAEs, and thus develop safer vaccines. Moreover, it may also be necessary to continually update the data of VAAEs.

    2013-01-01

    Multiple cholesterol-reducing therapies have been shown to induce the regression of tendon xanthoma in patients with familial hypercholesterolemia. We present 3 cases of adverse reactions in Achilles tendon xanthomas after the addition of niacin and bile acid sequestrants to ongoing statin therapy. Reduction in tendon dimensions and marked softening of xanthomas were interpreted as cholesterol removal from heavily infiltrated tissue sites. In 2 cases, changes in the xanthomas occurred despite only minor lipoprotein improvements, raising the possibility of direct drug effects in cholesterol-infiltrated tissue. Intriguingly, recent studies have described niacin receptor-mediated effects in macrophages. In summary, although adverse reactions in Achilles tendon xanthomas appear to be infrequent, clinicians should be aware of this phenomenon in their patients after intensifying lipid treatments, especially with the use of niacin in patients with familial hypercholesterolemia. Xanthoma responses may provide clues to new pharmacologic effects in cholesterol-infiltrated tissues.

    1983-06-01

    The mechanisms of anaphylactic reactions to muscle relaxants under general anesthesia are not completely understood. Extending an earlier study, we report 41 cases of anaphylactic shock investigated by intradermal skin tests with muscle relaxants (suxamethonium, pancuronium, gallamine, nortoxiferine), in vitro leukocyte histamine release, and Prausnitz-Kuestner tests. Intradermal tests were significantly positive at concentrations ranging from 10 to 10(5) times less than those in controls. Reproducibility tested for suxamethonium at a 1-year interval in five patients was good. Histamine release induced by muscle relaxants in Tris-albumin-Ca++-Mg++ buffer showed positive results in 8/25 instances and was inhibited by antigen excess in seven cases. Addition of 50% deuterium oxide (D2O) caused significant increase of histamine release in positive cases and induced release in all five negative cases studied. Muscle relaxant-induced histamine release was inhibited by in vitro anti-IgE leukocyte desensitization. The mean maximal histamine release dropped from 58.2% +/- 9.7 to 5.8% +/- 2 (p less than 0.01). Similarly, leukocyte desensitization also inhibited histamine release induced by anti-IgE but not by formyl-L-methionyl-L-leucyl-L-phenylalanine or poly-L-arginine. Prausnitz-Kuestner tests were positive in five out of 21 cases studied and became negative after heat inactivation. These results confirm the usefulness of intradermal skin tests in diagnosis of patients' reaction to muscle relaxants and suggest an IgE-mediated rather than an idiosyncratic mechanism.

  13. The mechanisms of sudden-onset type adverse reactions to oseltamivir.

    Hama, R; Bennett, C L

    2017-02-01

    Oseltamivir is contraindicated for people aged 10-19 in principle in Japan, due to concern about abnormal behaviours. Sudden death is another concern. This review examines growing evidence of their association and discusses underlying mechanisms of these sudden-onset type reactions to oseltamivir. First, the importance of animal models and the concept of human equivalent dose (HED) is summarized. Second, the specific condition for oseltamivir use, influenza infection, is reviewed. Third, findings from toxicity studies conducted prior to and after the marketing of oseltamivir are reported on to provide context on the observation of a possible causal association. Fourth, similarity and consistency of toxicity in humans with that in other animals is described. Finally, coherence of toxicokinetic and molecular level of evidence (channels, receptors and enzymes), including differences from the toxicity of other neuraminidase inhibitors, is reviewed. It is concluded that unchanged oseltamivir has various effects on the central nervous system (CNS) that may be related to clinical findings including hypothermia, abnormal behaviours including with fatal outcome, and sudden death. Among receptors and enzymes related to CNS action, it is known that oseltamivir inhibits nicotinic acetylcholine receptors, which are closely related to hypothermia, as well as human monoamine oxidase-A (MAO-A), which is closely related to abnormal or excitatory behaviours. Receptors such as GABAA , GABAB and NMDA and their related receptors/channels including Na(+) and Ca(2+) channels are thought to be other candidates for investigation related to respiratory suppression followed by sudden death and psychotic reactions (both acute and chronic), respectively.

    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.

    2017-01-01

    Introduction A new method to assess causality of suspected adverse drug reactions, the Liverpool Adverse Drug Reaction Causality Assessment Tool (LCAT), showed high interrater agreement when used by its developers. Our aim was to compare the interrater agreement achieved by LCAT to that achieved by another causality assessment method, the World Health Organization-Uppsala Monitoring Centre system for standardised case causality assessment (WHO-UMC system), in our setting. Methods Four raters independently assessed adverse drug reaction causality of 48 drug-event pairs, identified during a hospital-based survey. A randomised design ensured that no washout period was required between assessments with the two methods. We compared the methods’ interrater agreement by calculating agreement proportions, kappa statistics, and the intraclass correlation coefficient. We identified potentially problematic questions in the LCAT by comparing raters’ responses to individual questions. Results Overall unweighted kappa was 0.61 (95% CI 0.43 to 0.80) on the WHO-UMC system and 0.27 (95% CI 0.074 to 0.46) on the LCAT. Pairwise unweighted Cohen kappa ranged from 0.33 to 1.0 on the WHO-UMC system and from 0.094 to 0.71 on the LCAT. The intraclass correlation coefficient was 0.86 (95% CI 0.74 to 0.92) on the WHO-UMC system and 0.61 (95% CI 0.39 to 0.77) on the LCAT. Two LCAT questions were identified as significant points of disagreement. Discussion We were unable to replicate the high interrater agreement achieved by the LCAT developers and instead found its interrater agreement to be lower than that achieved when using the WHO-UMC system. We identified potential reasons for this and recommend priority areas for improving the LCAT. PMID:28235001

    Adverse drug reactions (ADRs) are one of the leading causes of hospital admissions and morbidity in developed countries and represent a substantial burden on healthcare delivery systems. However, there is little data available from low- and middle-income countries. This review compares the prevalence and characteristics of ADR-related hospitalisations in adults in developed and developing countries, including the mortality, severity and preventability associated with these events, commonly implicated drugs and contributing factors. A literature search was conducted via PubMed, Scopus, Web of Science, Embase, ProQuest and Google Scholar to find articles published in English from 2000 to 2015. Relevant observational studies were included. The median (with interquartile range [IQR]) prevalence of ADR-related hospitalisation in developed and developing countries was 6.3 % (3.3-11.0) and 5.5 % (1.1-16.9), respectively. The median proportions of preventable ADRs in developed and developing countries were 71.7 % (62.3-80.0) and 59.6 % (51.5-79.6), respectively. Similarly, the median proportions of ADRs resulting in mortality in developed and developing countries were 1.7 % (0.7-4.8) and 1.8 % (0.8-8.0), respectively. Commonly implicated drugs in both settings were antithrombotic, non-steroidal anti-inflammatory and cardiovascular drugs. Older age, female gender, number of medications, renal impairment and heart failure were reported to be associated with an increased risk for ADR-related hospitalisation in both settings while HIV/AIDS was implicated in developing countries only. The majority of ADRs were preventable in both settings, highlighting the importance of improving medication use, particularly in vulnerable patient groups such as the elderly, patients with multiple comorbidities and, in developing countries, patients with HIV/AIDS.

  5. Systematic review of antiretroviral-associated lipodystrophy: lipoatrophy, but not central fat gain, is an antiretroviral adverse drug reaction.

    Directory of Open Access Journals (Sweden)

    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.

As clinical trials in patients with rare diseases are limited, prescribers and patients have to rely on spontaneous adverse drug reaction (ADR reports for obtaining major information about the serious, rarely occurring, and unknown ADRs. In this study, we aimed to characterize ADRs reported for HAE medications in Europe from 2007 to 2013. ADR reports submitted for C1-inibitors and bradykinin receptor antagonists to the European ADR database, EudraVigilance (EV, were included in this study. The ADR reports were categorized with respect to age and sex of the patients, category of the reporter, type and seriousness of the reported ADRs, and medications. The unit of analysis was one adverse event (AE. Totally, 187 AEs were located in EV, and of these, 138 AEs were reported for Cinryze® (C1-inhibitor (73% of the total and 49 AEs for Firazyr® (icatibant (26% of the total AEs. Approximately 60% of all AEs were serious, including three fatal cases. Less than 5% of AEs were reported in children. In total, 62% of AEs were reported for women and 38% for men. For both Cinryze® and Firazyr®, the majority of reported AEs were of the type “general disorders and administration site conditions”. For Cinryze®, a large number of AEs of the type “HAE” and “drug ineffective” was reported, but only few of these were serious. For Firazyr®, several nonserious reports on injection site reactions were reported. In conclusion, this study showed that in EV, several ADR reports from use of HAE medications were identified, and a large number of these were

    2010-12-01

    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.

    A 30-year old white male presented with sharply demarcated pruritic lesions in a black and red tattoo on his wrist. The strongly infiltrated and slightly scaly eruptions started four months after tattoo application and were notably restricted to the red-colored areas. Symptoms got worse after UV exposure. Patch testing and photo patch testing with the used azo dye Pigment Red 170 (C.I. 12475) was negative. Histology revealed lichenoid dermatitis without signs of a granulomatous reaction. The verification of allergic sensitization in hypersensitivity reactions to tattoos by patch testing may be difficult due to the poor penetration into the skin of the applied azo pigments. Intradermal testing may be more sensitive but bears the risk of long lasting skin reactions.

  14. Statin-associated muscular and renal adverse events: data mining of the public version of the FDA adverse event reporting system.

    Toshiyuki Sakaeda

    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.

    2013-10-01

    : The majority of cutaneous hypersensitivity reactions to exogenous tattoo pigments can be histologically classified as lichenoid or granulomatous. The etiology is still uncertain but is generally accepted to be a delayed-type hypersensitivity reaction to either the pigment itself or its carrier solution. In this report, we review the literature concerning adverse reactions to tattoos. In addition, we describe the second case of a localized granulomatous dermatitis to the red dye within a tattoo that histologically resembled granuloma annulare. This is the first reported example of a perforating granuloma annulare-like reaction.

    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

    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.

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.

    Full Text Available THIS ARTICLE WAS RETRACTED AFTER A PLAGIARISM INVESTIGATIONObjective: To assess the incidence, severity pattern, causality, predictability and preventability of adverse drug reactions (ADRs and to identify risk factors for adverse drug reactions in highly active antiretroviral therapy.Methods: Enrolled patients were intensively monitored for ADRs to highly active antiretroviral therapy. Predictability was assessed based on history of previous exposure to the drug or literature incidence of ADRs. Preventability was assessed using Schumock and Thornton criteria and severity was assessed using modified Hartwig and Siegel scale. Multivariate logistic regressions were used to identify the risk factors for ADRs.Results: Monitoring of 130 retropositive patients by active pharmacovigilance identified 74 ADRs from 57 patients. Anemia and hepatotoxicity were the most commonly observed ADRs. The organ system commonly affected by ADR was red blood cell (21.4%.The ADRs were moderate in 77% of cases. Type A reactions (77% were more common. A total of 10.8% ADRs were definitely preventable. The incidence rate of ADRs (65.9% was highest with Zidovudine + Lamivudine + Nevirapine combination. A total of 84% interruptions to highly active antiretroviral therapy were due to toxicity. CD4 less than 200 cells/µl, female gender and tuberculosis were observed as risk factors for ADRs.Conclusion: Incidence of ADRs in intensively monitored patients was found to be 43.8%. Anemia in HIV patients is an influential risk factor for occurrence of ADRs. With the increasing access to antiretroviral in India, clinicians must focus on early detection and prevention of ADRs to highly active antiretroviral therapy.

    In this issue of the Journal of Bacteriology, Chonoles Imlay et al. (K. R. Chonoles Imlay, S. Korshunov, and J. A. Imlay, J Bacteriol 197:3629-3644, 2015, http://dx.doi.org/10.1128/JB.00277-15) show that oxidative stress kills sulfur-restricted Escherichia coli grown with sublethal H2O2 when challenged with cystine. Killing requires rapid and seemingly unregulated cystine transport and equally rapid cystine reduction to cysteine. Cysteine export completes an energy-depleting futile cycle. Each reaction of the cycle could be beneficial. Together, a cystine-mediated vulnerability emerges during the transition from a sulfur-restricted to a sulfur-replete environment, perhaps because of complexities of sulfur metabolism.

    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. Furthermore, sufficient support and resources are required for the implementation of RCA recommendations in clinical practice.

    2013-01-01

    Background: In the United States, hip fracture rates have declined by 30% coincident with bisphosphonate use. However, bisphosphonates are associated with sporadic cases of atypical femoral fracture. Atypical femoral fractures are usually atraumatic, may be bilateral, are occasionally preceded by prodromal thigh pain, and may have delayed fracture-healing. This study assessed the occurrence of bisphosphonate-associated nonhealing femoral fractures through a review of data from the U.S. FDA (Food and Drug Administration) Adverse Event Reporting System (FAERS) (1996 to 2011), published case reports, and international safety efforts. Methods: We analyzed the FAERS database with use of the proportional reporting ratio (PRR) and empiric Bayesian geometric mean (EBGM) techniques to assess whether a safety signal existed. Additionally, we conducted a systematic literature review (1990 to February 2012). Results: The analysis of the FAERS database indicated a PRR of 4.51 (95% confidence interval [CI], 3.44 to 5.92) for bisphosphonate use and nonhealing femoral fractures. Most cases (n = 317) were attributed to use of alendronate (PRR = 3.32; 95% CI, 2.71 to 4.17). In 2008, international safety agencies issued warnings and required label changes. In 2010, the FDA issued a safety notification, and the American Society for Bone and Mineral Research (ASBMR) issued recommendations about bisphosphonate-associated atypical femoral fractures. Conclusions: Nonhealing femoral fractures are unusual adverse drug reactions associated with bisphosphonate use, as up to 26% of published cases of atypical femoral fractures exhibited delayed healing or nonhealing.

    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.

    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)

    Drug safety is a very basic and fundamental concept in medical practice. ADRs play an important role in assessing patient safety in any system of medicine. Pharmacovigilance study is thus significant to understand treatment outcomes. Current raised issue with respect to complementary and alternative system medicine (CAM) like Ayurveda is increased in number of safety reports along with report misinterpretation; this generates the negative impact on system. Although, Ayurveda which is holistic system of medicine from India has elaborated the causes and methods of drug-induced consequences along with preventive measures the available data in classical texts is scattered. The compilation and analysis along with modern concept drug safety is need of the hour. Present literature review was conducted from various compendium of Ayurveda and electronic data base with search terms of 'Vyapad', 'Viruddha', 'Ahita', 'herb-herb interaction', 'idiosyncrasy', 'Prakritiviruddha' etc. The reported information was analysed for the possible correlation on concept of ADR and Pharmacovigilance of current science. Overall review demonstrated that drug interaction, iatrogenic, over dose, administration of unsuitable drugs, reprehensive drug administration with respect to disease, complication from five procedural therapies (Panchakarma) and reprehensible preparation of mineral drug are nearer to the modern causes of ADR. Thus, concept of drug safety and ADR is not new to the Ayurveda. The concept "Drug which is not appropriate to be used as medicine"(Abheshaja) of Ayurveda sounds similar as that of modern pharmacovigilance.

    The WHO-ART and MedDRA terminologies used for coding adverse drug reactions (ADR) do not provide formal definitions of terms. In order to improve groupings, we propose to map ADR terms to equivalent Snomed CT concepts through UMLS Metathesaurus. We performed such mappings on WHO-ART terms and can automatically classify them using a description logic definition expressing their synonymies. Our gold standard was a set of 13 MedDRA special search categories restricted to ADR terms available in WHO-ART. The overlapping of the groupings within the new structure of WHO-ART on the manually built MedDRA search categories showed a 71% success rate. We plan to improve our method in order to retrieve associative relations between WHO-ART terms.

    Adverse drug reactions (ADRs) are a common, and often preventable, cause of hospital admission, especially in the elderly, and can occur during hospitalization. In this current opinion article, we present three cases of recurrence of a serious ADR due to re-prescription of a withdrawn medication that highlight the need for a system to prevent the undesirable re-prescription of medications withdrawn because of an ADR. In addition, we describe an electronic system that could help prevent undesirable re-prescription following an ADR. Such a system should document ADRs systematically at the patient level, make this information available to relevant healthcare providers and the patient, and flag re-prescription of the offending drug. The effectiveness and cost effectiveness of such a system would need to be determined.

    The diagnosis of adverse local tissue reaction (ALTR) after metal-on-metal total hip arthroplasty (MoMTHA) presents a significant challenge. No single biomarker is specific for ALTR. The purpose of this study was to determine if the ratio of cobalt to chromium ions is useful for diagnosing ALTR in MoMTHA. In 89 bearing-related revision THAs, preoperative cobalt and chromium ion levels were compared to an intraoperative soft tissue damage grading scale. The average cobalt to chromium ratio was 2.96 (0-20). There was no correlation between the tissue scale and the cobalt to chromium ratio (R=0.095; P=0.41). Many variables affecting ion production/excretion mitigate the use of the ion ratio. The cobalt to chromium ratio is not a predictive biomarker for ALTR in MoMTHA.

    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.

  18. The effect of prophylactic antipyretic administration on post-vaccination adverse reactions and antibody response in children: a systematic review.

    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

    Finasteride has proved to be relatively safe and effective in the therapeutic management of male androgenic alopecia. However, literature data report several endocrine imbalances inducing various adverse effects, which often persist after treatment cessation in the form of post-finasteride syndrome. Here we present the case of a 52-year-old man receiving finasteride (1 mg/day) who developed an uncommon adverse effect represented by generalized vitiligo 2 months after finasteride discontinuation. Associated adverse effects encountered were represented by mild sexual dysfunction (as determined by the International Index of Erectile Function, IIEF) and moderate depressive symptoms (according to DSM-V criteria), all of these manifestations aggregating within/as a possible post-finasteride syndrome. Further studies should develop and compare several therapeutic approaches, taking into account not only compounds that decrease the circulating dihydrotestosterone level but also those that could block the dihydrotestosterone receptors (if possible, compounds with selective tropism towards the skin). In addition, the possibility of predicting adverse effects of finasteride (according to hand preference and sexual orientation) should be taken into account.

    2012-01-01

    Full Text Available Background: The prevalence, clinical patterns, and causative drugs of cutaneous adverse drug reactions (cADR vary among the different populations previously studied. Aim: To determine the prevalence, the clinical patterns of drug eruptions, and the common drugs implicated, particularly in severe cADR such as Stevens-Johnson Syndrome/Toxic epidermal necrolysis (SJS/TEN and drug rash with eosinophilia and systemic symptoms (DRESS in our population. Methods: We analyzed the database established for all cADR seen by the department of Dermatology from January 2001 till December 2010. Results: A total of 362 cADR were seen among 42 170 new clinic attendees, yielding an incidence rate of 0.86%. The most common reaction pattern seen was maculopapular eruption (153 cases followed by SJS/TEN (110 cases and DRESS (34 cases. Antibiotics was the most commonly implicated drug group (146 cases followed by anticonvulsants (81 cases and antigout drugs (50 cases. The most frequently implicated drug was allopurinol (50 cases. Carbamazepine, allopurinol, and cotrimoxazole were the three main causative drugs of SJS/TEN accounting for 21.8%, 20.9%, and 12.7%, respectively, of the 110 cases seen, whereas DRESS was mainly caused by allopurinol (15 cases. Mortality rates for TEN, SJS, and DRESS were 28.6%, 2.2%, and 5.9%, respectively Conclusions: The low rate of cADR with a high proportion of severe reactions observed in this study was probably due to referral bias. Otherwise, the reaction patterns and drugs causing cADR in our population were similar to those seen in other countries. Carbamazepine, allopurinol, and cotrimoxazole were the three main causative drugs of SJS/TEN in our population.

    Selective agents able to locate and identify unique targets represent a crucial aspect of modern pharmacology. The exclusive location of sodium-glucose co-transporter-2 (SGLUT2) on kidneys prompt companies to develop SGLT2 inhibitors that today are the latest class of drugs for diabetes treatment. In particular, canagliflozin blocks the re-absorption of glucose in the kidney lowering blood glucose levels by increasing glucose excretion. We report a 61-year old woman who developed an intense and severe pruritus during the treatment with canagliflozin. Clinical and laboratory findings excluded the presence of systemic or skin diseases able to induce pruritus. The discontinuation of canagliflozin and the treatment with pioglitazone/metformin fixed combination induced a remission of pruritus. This case emphasizes the need to consider pruritus as a differential diagnosis during the treatment with canagliflozin.

    Pain management is important when dealing with pediatric dental patients. The use of local anesthetics can be especially challenging for children taking psychotropic medications. The purpose of this paper was to identify pertinent information regarding drug interactions between vasoconstrictor/local anesthetic combinations and medications for the management of psychiatric or behavior disorders in children. Many of the reported interactions are controversial, largely theoretical with very limited clinical evidence, and not well defined. However, when considering the potential for significant increased blood pressure when local anesthesia containing a vasoconstrictor is used, a thorough under standing of the pharmacological actions of medications used to treat psychiatric or behavioral disorders and vasoconstrictors can help dental professionals minimize the potential risk of drug interactions in their practice.

    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.

    2015-03-01

    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.

    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.

    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

    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.

    Purpose: To determine whether acute kidney injury (AKI) is identified within the US Food and Drug Administration's Adverse Events and Reporting System (FDA AERS) as an adverse event resulting from bisphosphonate (BP) use in cancer therapy. Methods: A search of the FDA AERS records from January 1998 through June 2009 was performed; search terms were “renal problems” and all drug names for BPs. The search resulted in 2,091 reports. We analyzed for signals of disproportional association by calculating the proportional reporting ratio for zoledronic acid (ZOL) and pamidronate. Literature review of BP-associated renal injury within the cancer setting was conducted. Results: Four hundred eighty cases of BP-associated acute kidney injury (AKI) were identified in patients with cancer. Two hundred ninety-eight patients (56%) were female; mean age was 66 ± 10 years. Multiple myeloma (n = 220, 46%), breast cancer (n = 98, 20%), and prostate cancer (n = 24, 5%) were identified. Agents included ZOL (n = 411, 87.5%), pamidronate (n = 8, 17%), and alendronate (n = 36, 2%). Outcomes included hospitalization (n = 304, 63.3%) and death (n = 68, 14%). The proportional reporting ratio for ZOL was 1.22 (95% CI, 1.13 to 1.32) and for pamidronate was 1.55 (95% CI, 1.25 to 1.65), reflecting a nonsignificant safety signal for both drugs. Conclusion: AKI was identified in BP cancer clinical trials, although a safety signal for BPs and AKI within the FDA AERS was not detected. Our findings may be attributed, in part, to clinicians who believe that AKI occurs infrequently; ascribe the AKI to underlying premorbid disease, therapy, or cancer progression; or consider that AKI is a known adverse drug reaction of BPs and thus under-report AKI to the AERS.

    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.

    Assessment of treatment safety is 1 of the primary goals of clinical trials. Organizations and working groups have created reporting guidelines for adverse events (AEs). Previous research examining AE reporting for pharmacologic clinical trials of analgesics in major pain journals found many reporting inadequacies, suggesting that analgesic trials are not adhering to existing AE reporting guidelines. The present systematic review documented AE reporting in 3 main pain journals for nonpharmacologic, noninterventional (NP/NI) trials examining pain treatments. To broaden our pool of nonpharmacologic trials, we also included trials examining acupuncture, leech therapy, and noninvasive stimulation techniques (eg, transcutaneous electrical nerve stimulation). We documented AE reporting at 2 levels of specificity using coding manuals based on the Consolidated Standards of Reporting Trials (CONSORT) harms reporting standards and Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) AE reporting checklist. We identified a number of inadequacies in AE reporting across the 3 journals. For example, using the ACTTION coding manual, we found that less than one-half of the trials reported specific AE assessment methods; approximately one-third of the trials reported withdrawals due to AEs for each study arm; and about one-fourth of the trials reported all specific AEs. We also examined differences in AE reporting across several trial characteristics, finding that AE reporting was generally more detailed in trials with patients versus those using healthy volunteers undergoing experimentally evoked pain. These results suggest that investigators conducting and reporting NP/NI clinical trials are not adequately describing the assessment and occurrence of AEs.

    Neurological adverse events following administration of the 17DD substrain of yellow fever vaccine (YEL-AND) in the Brazilian population are described and analyzed. Based on information obtained from the National Immunization Program through passive surveillance or intensified passive surveillance, from 2007 to 2012, descriptive analysis, national and regional rates of YFV associated neurotropic, neurological autoimmune disease, and reporting rate ratios with their respective 95% confidence intervals were calculated for first time vaccinees stratified on age and year. Sixty-seven neurological cases were found, with the highest rate of neurological adverse events in the age group from 5 to 9 years (2.66 per 100,000 vaccine doses in Rio Grande do Sul state, and 0.83 per 100,000 doses in national analysis). Two cases had a combination of neurotropic and autoimmune features. This is the largest sample of YEL-AND already analyzed. Rates are similar to other recent studies, but on this study the age group from 5 to 9 years of age had the highest risk. As neurological adverse events have in general a good prognosis, they should not contraindicate the use of yellow fever vaccine in face of risk of infection by yellow fever virus.

    The prescription ot fluoroquinolones has been constantly increasing over the past decade. consequently, an increasing number of hyper-sensitivity reactions and adverse events have been reported. The aim of the review is to discuss the incidence of hypersensitivity reactions either IgE (immediate) or T cells mediated (delayed). We will make an overview ofthe diagnostic tools available to detect such hypersensitivity reactions. Finally, the specific adverse events associated with fluoroquinolones, including tendinopathy, chondrotoxicity, peripheral neuropathy or retinal detachment will be discussed.

    The Vaccine Adverse Event Reporting System (VAERS), administered by the FDA and CDC, is the U.S. system for surveillance of vaccine adverse events (AE). Acute encephalopathy age or =18 months (EO > or = 18), encephalitis (EI), and multiple sclerosis (MS) after vaccination have been reported to VAERS, but reports often contain insufficient information to validate diagnoses. Standardized case definitions would enhance the utility of VAERS reports for AE surveillance. We developed practical case definitions for classification of VAERS reports, and three neurologists independently applied the definitions to reports submitted in 1993. Inter-observer agreement was assessed, and non-concordant classifications were reviewed in a follow-up conference call. Reports of EO or = 18 (n = 20), EI (n = 15), and MS (n = 16) were classified as "definite" in 7% to 30% of the cases, while 26% to 51% of reports were thought to have insufficient information to make a classification. Agreement among reviewers was good to excellent, (kappa: 0.65 to 0.85) except for EO Elsevier Science Inc.

    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.

    Full Text Available 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.

    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.

    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.

    2014-01-01

    Adverse events cause suffering and increased costs in health care. The main way of registering adverse event is through dental personnel's reports, but reports from patients can also contribute to the knowledge of such occurrences. This study aimed to analyse the adverse events reported by dental personnel and patients in public dental service (PDS) in a Swedish county. The PDS has an electronic system for reporting and processing adverse events and, in addition, patients can report shortcomings, as regards to reception and treatment, to a patient committee or to an insurance company. The study material consisted of all adverse events reported in 2010 and 2011, including 273 events reported by dental personnel, 53 events reported by patients to the insurance company and 53 events reported by patients to the patient committee. Data concerning patients' age and gender, the nature, severity and cause of the event and the dental personnel's age gender and profession were collected and analysed. Furthermore the records describing the dental personnel's reports from 2011 were studied to investigate if the event had been documented and the patient informed. Age groups 0 to 9 and 20 to 39 years were underrepresented while those between the ages 10 to 19 and 60 to 69 years were overrepresented in dental personnel's reports. Among young patients delayed diagnosis and therapy dominated and among patients over 20 years the most frequent reports dealt with inadequate treatments, especially endodontic treatments. In 29% of the events there was no documentation of the adverse event in the records and 49% of cases had no report about patient information. The majority of the reports from dental personnel were made by dentists (69%). Reporting adverse events can be seen as a reactive way of working with patient safety, but knowledge about frequencies and causes of incidents is the basis of proactive patient safety work.

Methods References in the last decades at home and abroad about Senecio scandens clinical reports of adverse reactions were collated, analyzed and summarized. Results The most serious adverse reaction of Senecio scandens is hepatotoxicity, which is related to the long-term use, dosage, a mixture of varieties, compatibility, preparation technology and the difference of individual, and especially long-term use is the main cause of death of clinical cases. Studies have shown that pyrrolizidine alkaloids (PAs) contained in Senecio scandens are the main material basis of hepatotoxicity. Conclusion For the causes of Senecio scandens clinical adverse reactions, the hepatotoxicity damage regularity and material basis of Senecio scandens and its Chinese traditional patent medicine should be urgently studied, and intracorporal process of toxic substances and "toxicodynamics-toxicokinetics" relevance

    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

    Psychiatric patients report higher levels of victimisation and are at risk for further victimisation in different contexts, such as psychiatric institutions. Studies in this field tend to focus on hospital staff as victims, experiencing classic forms of victimisation (e.g. physical assault, threats, verbal abuse), through qualitative studies. This is a quantitative retrospective study that aims to know the occurrence of psychiatric victimisation and other adverse experiences in Portuguese psychiatric patients. Ninety-five psychiatric patients, between 20 and 79 years old (M - 45.18, SD - 13.06), with a history of psychiatric hospitalisation answered the Experiences in Psychiatric Institution Inventory. Participants were recruited in four psychiatric hospitals. Inpatients were approached during their hospitalisation; outpatients were approached in scheduled appointment days. Only 23 (24.2%) participants reported no victimisation. Total Experiences of Self varied from 0 to 7 (M - 1.75, SD - 1.72), Total Witnessed Experiences varied from 0 to 7 (M - 1.17, SD - 1.64), and Total Global Experiences varied from 0 to 14 (M - 2.92, SD - 3.01). These results show that victimisation and adverse experiences in psychiatric contexts are frequent and go beyond classic forms of victimisation. A deeper knowledge of these experiences and their impact in the mental health of psychiatric patients may promote quality of care provided and lead to more effective treatments, thus reducing the number and length of hospitalisations, and the financial burden for public health services.

    2014-01-01

    We reviewed cranial nerve palsies, other than VII, that have been reported to the US Vaccine Adverse Event Reporting System (VAERS). We examined patterns for differences in vaccine types, seriousness, age, and clinical characteristics. We identified 68 reports of cranial nerve palsies, most commonly involving the oculomotor (III), trochlear (IV), and abducens (VI) nerves. Isolated cranial nerve palsies, as well as palsies occurring as part of a broader clinical entity, were reported. Forty reports (59%) were classified as serious, suggesting that a cranial nerve palsy may sometimes be the harbinger of a broader and more ominous clinical entity, such as a stroke or encephalomyelitis. There was no conspicuous clustering of live vs. inactivated vaccines. The patient age range spanned the spectrum from infants to the elderly. Independent data may help to clarify whether, when, and to what extent the rates of cranial nerve palsies following particular vaccines may exceed background levels.

  20. 'Case reporting of rare adverse events in otolaryngology': can we defend the case report?

    Dias, Andrew

    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.

    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

However, since the circadian rhythms of growth and proliferation of various cancer cells often differ, the question of whether the administration of platinum anticancer drugs at different times of the day exerts significantly different efficacy and adverse effects on oral cancers remains to be elucidated. This study has compared the efficacy and adverse effects of oxaliplatin (L-OHP administration at different times during a day on oral squamous cell carcinoma in mice and has analyzed cellular circadian rhythms. Methods: The mouse model for oral squamous cell carcinoma was established in 75 nude mice, housed in a 12 hour light/12 hour dark cycle environment. The mice were randomly divided into five groups; four experimental groups were intravenously injected with L-OHP at four time points within a 24-hour period (4, 10, 16, and 22 hours after lights on [HALO]. The control group was intravenously injected with the same volume of saline. Treatment efficacy and adverse reactions were compared on the seventh day after the injection, at 22 HALO. The existence of circadian rhythms was determined by cosine analysis. Results: Only injections of L-OHP at 16 and 22 HALO significantly prolonged animal survival time. The adverse reactions in mice injected with L-OHP at 16 and 22 HALO were significantly less than those observed in mice administered L-OHP at 4 and 10 HALO

    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.

    Cyclophosphamide (CPA)-based combination treatment has known to be effective for breast cancer, but often causes adverse drug reactions (ADRs). Hence, the identification of patients at risk for toxicity by CPA is clinically significant. In this study, a stepwise case-control association study was conducted using 403 patients with breast cancer who received the CPA combination therapy. A total of 143 genetic polymorphisms in 13 candidate genes (CYP2B6, CYP2C9, CYP2C19, CYP3A4, CYP3A5, ALDH1A1, ALDH3A1, GSTA1, GSTM1, GSTP1, GSTT1, ABCC2 and ABCC4), possibly involved in the activation, metabolism and transport of CPA, were genotyped using 184 cases who developed either > or =grade 3 leukopenia/neutropenia or > or =grade 2 gastrointestinal toxicity and 219 controls who did not show any ADRs throughout the treatment. The association study revealed that one SNP, rs9561778 in ABCC4, showed a significant association with CPA-induced ADRs (Cochran-Armitage trend's P-value=0.00031; odds ratio (OR)=2.06). Subgroup analysis also indicated that the SNP rs9561778 was significantly associated with two major ADR subgroups; gastrointestinal toxicity and leukopenia/neutropenia (Cochran-Armitage trend's P-value=0.00019 and 0.014; OR=2.31 and 1.83). Furthermore, the SNP rs9561778 showed an association with breast cancer patients who were treated with CA(F) drug regimen-induced ADR (Cochran-Armitage trend's P-value=0.00028; OR=3.13). The SNPs in ABCC4 might be applicable in predicting the risk of ADRs in patients receiving CPA combination chemotherapy.

    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 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.

    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

    Full Text Available The wide-scale roll-out of artemisinin combination therapies (ACTs for the treatment of malaria should be accompanied by continued surveillance of their safety. Post-marketing pharmacovigilance (PV relies on adverse event (AE reporting by clinicians, but as a large proportion of treatments are provided by non-clinicians in low-resource settings, the effectiveness of such PV systems is limited. To facilitate reporting, AE forms should be easily completed; however, most are challenging for lower-level health workers and non-clinicians to complete. Through participatory research, we sought to develop user-friendly AE report forms to capture information on events associated with ACTs.Following situation analysis, we undertook workshops with community medicine distributors and health workers in Jinja, Uganda, to develop a reporting form based on experiences and needs of users, and communication and visual perception principles. Participants gave feedback for revisions of subsequent versions. We then conducted 8 pretesting sessions with 77 potential end users to test and refine passive and active versions of the form.The development process resulted in a form that included a pictorial storyboard to communicate the rationale for the information needed and facilitate rapport between the reporter and the respondent, and a diary format to record the drug administration and event details in chronological relation to each other. Successive rounds of pretesting used qualitative and quantitative feedback to refine the form, with the final round showing over 80% of the form completed correctly by potential end users.We developed novel AE report forms that can be used by non-clinicians to capture pharmacovigilance data for anti-malarial drugs. The participatory approach was effective for developing forms that are intuitive for reporters, and motivating for respondents. The forms, or their key components, could be adapted for use in other low-literacy settings

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.

    Objective To analyze the possible reasons of blood transfusion adverse reactions and consti-tute the counteractions for further reducing or preventing similar blood transfusion adverse reactions.Methods The fifty-nine cases of blood transfusion adverse reactions and all the 44983 person-time of blood transfu-sion were collected between January 2013 and December 2014.And then we analyzed the time-lag,the inci-dence rate of BTAR in different blood products,the harm of the body from BTAR,department and patients’ outcome.Results All the BTAR occurred in the 6 hours in the beginning of blood transfusion, which were called acute transfusion reactions.Skin allergy and fervescence were the major symptoms of acute transfusion reaction.The blood products of blood transfusion adverse reactions included virus inactivated frozen plasma, platelets,cryoprecipitate, and suspended leukocyte reduced red blood cells.Among the blood products of transfusion adverse reactions,the BTAR incidence rate of plasma occupy the multiple.The ICU were the ma-jor department.After treatment, the damage caused by adverse reactions were recovered.Conclusion The occurrence of blood transfusion adverse reactions were mainly patients themselves allergic to immunoglobu-lin within the plasma,or the patients had produced leucocyte antibody.By symptomatic treatment,it was to give antiallergic drug and febrifuge before blood transfusion routinely and the antigen in coordination with each other and leukocyte reduced blood products which could reduce or avoid the occurrence of blood trans-fusion adverse reactions.%目的:分析发生输血不良反应( blood transfusion adverse reactions,BTAR)的可能原因并制订应对措施,进一步减少或避免类似BTAR的发生。方法收集2013年1月至2014年12月期间发生的BTAR 59例及所有输血人次44983人次,分析发生BTAR的时滞、不同血制品的不良反应发生率、不良反应对机体的危害、科室分布及患者预

    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.

    Background: Direct patient-reported information about adverse drug events (ADEs) is important since it adds to healthcare professional-reported information about the safety of drugs. Previously, we developed an instrument to assess patient-reported ADEs in research settings. The aim of this study is
