They have a significant cost both financially and in terms of quality of life. Few studies of ADRs have been carried out in the community so the effect on primary care is harder to assess, but studies in the hospital environment have shown the following. ...

Drug Hypersensitivity Reactions

Adverse drug reactions (ADRs) are an important public health problem. An ADR is defined by the World Health Organization as an unintended, noxious response to a drug that occurs at a dose usually tolerated by normal subjects. The classification of ADRs by Rawlins and Thompson divides ADRs into two major subtypes: (1) type A reactions, which are dose dependent and predictable, and (2) type B reactions, which are uncommon and unpredictable. The majority of ADRs are type A reactions, which include four subtypes: overdosage or toxicity, side effects, secondary effects, and interactions. Type B reactions constitute approximately 10 to 15% of all ADRs and include four subtypes: drug intolerance, idiosyncratic reactions, pseudoallergic reactions, and drug hypersensitivity reactions. This chapter reviews the epidemiology of ADRs, risk factors for drug hypersensitivity reactions, the classification of drug reactions, diagnostic tests, reactions to specific drugs, and management of the patient with drug allergy. Figures illustrate drugs as haptens and prohaptens, the Gell and Coombs system, the four basic immunologic mechanisms for drug reactions, the chemical structure of different β-lactam antibiotics, penicillin skin testing, sulfonamide metabolism and haptenation, nonsteroidal antiinflammatory drug effects, and patient management. Tables outline the classification of ADRs, drugs frequently implicated in allergic drug reactions, and reagents and concentrations recommended for prick and intradermal skin testing. This review contains 8 figures, 7 tables, and 60 references.

The article outlines the benefits and risks of vaccines. Vaccine safety and myths and misinformation, the general review of the importance of the vaccines. Steps involved in the Development of Vaccines and also illustrates the immunization importance and its disadvantages. Administration of vaccines in different age groups. Classification of different available vaccines in the health market. Also stating the possible adverse drug reactions / potential side effects of the vaccines and their monitoring and management of adrs. We concluded that Vaccine acceptance must be widespread in order to provide herd immunity so that individuals who cannot be directly protected by vaccination are protected by communal immunity. The danger is quite low, and the advantages of vaccinations usually outweigh it.

The Cost

The aim of the review article was to highlight the methodologies for assessing the financial costs of adverse drug reactions exemplified by the Russian Federation and Brazil.Materials and methods: for a comparative analysis, materials from open sources were used. The study of the experience of methods used for assessing the burden of adverse drug reactions, was carried out using the system for calculating payments for medical care by clinical-statistical and clinical-profile groups, the methodology for assessing the severity of adverse events of the US National Cancer Institute, drug-associated problems, and “the decision tree” model.Results. When comparing the costs of ADR management in the Russian Federation and Brazil, the following results have been obtained: in the Russian Federation, the “cost” of reaction can be estimated only for a limited number of nosological groups that are regulated by the classification of diseases by clinical and statistical groups; in Brazil, when predicting the costs of adverse reactions management, the combination of “the decision tree” method and the Delphi method is used. In the Russian Federation, the cost of the 3rd and above severity adverse event (according to CTCAE v. 4.03), varies from 26,849.22 up to 26,196.37 RUB in the North-West region (St. Petersburg). In Brazil, the cost of ADR ranges from 13 USD (the best scenario for the patient) to 574 USD (the worst scenario for the patient), which is about 975 and 43,000 RUB, respectively. The introduction of methods that make it possible to predict the development and potential outcomes of adverse drug reactions, as well as taking into account the experiences of foreign colleagues in their modeling, will reduce economic costs in the Russian Federation at the federal level.Conclusion: for the economic value analysis and further forecasting, an improvement of existing methodologies is required. The models used in the Russian Federation (“the decision tree”, classification of diseases by clinical groups, Markov model) do not take into account the time factor, therefore, when planning the analysis of potential costs for adverse reactions, it is necessary to reinforce the methods with such tools as QALY, YLL, and YLD.
