          Abstract

          Com o objetivo de avaliar os custos e a efetividade das 2 formas de tratamento mais utilizadas em nosso meio para a Doença de Graves, iodo radioativo e tratamento clínico prolongado, analisamos pacientes submetidos a essas terapias na região de Maringá, PR. Foram estudados 23 pacientes, 7 homens e 16 mulheres, com idade média de 35,4 anos, submetidos ao tratamento clínico, e 34 pacientes, 5 homens e 29 mulheres, com idade média de 39,4 anos, submetidos à dose terapêutica com iodeto de sódio (iodo-131). Após 2 anos de tratamento clínico com tiamazol (Tapazol®), 21 pacientes atingiram o eutireoidismo e dois permaneceram hipertireóideos. No grupo da dose terapêutica com iodeto de sódio (iodo-131), 21 pacientes evoluíram para o hipotireoidismo, enquanto que 13 atingiram o eutireoidismo. Para o cálculo do custo de cada modalidade de tratamento, analisamos o número de consultas necessárias durante o seguimento, exames complementares solicitados e medicações utilizadas, como tiamazol e/ou tiroxina. O grupo submetido ao tratamento clínico necessitou de maior número de consultas e exames, sendo que o custo médio foi de R\(1.345,81 neste período de dois anos, enquanto que no grupo com iodeto de sódio (iodo-131) o valor médio foi de R\) 622,94. Assim, os custos da dose terapêutica com iodeto de sódio (iodo-131) foram 53,7% menores do que o tratamento clínico com drogas antitireoidianas. Este trabalho demonstra que o tratamento com dose terapêutica com iodeto de sódio (iodo-131) apresenta um menor custo, sendo bastante efetivo no controle do hipertireoidismo na doença de Graves.

          Translated abstract

          In this study, we set out to evaluate the costs and effectiveness of the 2 most used therapies in our region, ATD or RAI. 23 patients, 6 men and 16 women, with a mean age of 35.4 years, treated with ATD, and 35 patients, 5 men and 30 women, mean age of 39.4 years, treated with RAI, were studied. After 2 years receiving ATD, 21 patients achieved euthyroidism and 2 remained hyperthyroid. In the RAI group, 21 patients presented hypothyroidism and 13 became euthyroid. To calculate the costs of each therapy, we analyzed the number of visits during this period, the laboratory data and the drugs needed, such as tiamazol and/or thyroxine. The group treated only with ATD needed a higher number of visits and laboratory measurements, with the mean total cost of R\(1,345.81, while the RAI group spent a mean amount of R\) 622.94. Therefore, the costs of the RAI treatment were 53.5% lower than clinical therapy with ATD. The present study demonstrates that RAI treatment has a lower cost than ATD, being very effective in controlling the hyperthyroidism of Graves’ disease.

          The management of hyperthyroidism.

          Although effective treatments for hyperthyroidism are available, none is perfect. Particularly with respect to Graves' disease, what is needed is a therapy directed at modulating the disease process itself rather than merely reducing the synthesis and secretion of thyroid hormones in the hope that the underlying Graves' disease will remit. Greater understanding of the pathogenesis of Graves' disease, resulting from cloning of the thyrotropin receptor and better knowledge of the interactions between these receptors or other thyroid antigens and the immune system, may lead to such treatment. Broad-spectrum immunosuppression, with all its side effects, is not the answer; more focused therapies to inhibit the immune response to specific thyroid antigens may represent the treatment of the future. Meanwhile, radioiodine therapy is the most effective and convenient method of achieving long-term control of hyperthyroidism, although at the cost of hypothyroidism in many patients.

            Quality of life aspects and costs in treatment of Graves' hyperthyroidism with antithyroid drugs, surgery, or radioiodine: results from a prospective, randomized study.

            The patients' views and costs of three different forms of treatment for Graves' hyperthyroidism were investigated. The study comprises 174 patients with Graves' hyperthyroidism who were stratified into two age groups: 20 to 34 years and 35 to 55 years. The younger group was randomly assigned to treatment with antithyroid drug plus thyroxine for 18 months or subtotal thyroidectomy, and in the older group iodine-131 was added as a third alternative. The patients' views of their therapy were based on a questionnaire formulated to identify possible differences between the three treatment forms. The costs were assessed by analyzing the official hospital reimbursement system for both outpatient and inpatient costs for a period of 2 years from the day of randomization. The results show that no significant differences in opinion were found between the five treatment groups with regard to any of the questions. Furthermore, only 10% of the patients expressed slight and 3% major hesitation to recommend the treatment form received to a friend with similar disease. Twenty percent of the patients with endocrine ophthalmopathy reported the eye problems to be much more troublesome and 14% somewhat more troublesome than the thyroid problems. The cost proportion between the medical and surgical treatment in the young group was 1:2.5 (1 = 1126 United States dollars [USD]) before and 1:1.3 (1 = 2284 USD) after inclusion of the relapse costs. The proportion between the medical, surgical, and iodine-131 treatment in the older group was 1:2.5:1.6 (1 = 1164 USD) before and 1:1.6:1.4 (1 = 1972 USD) after inclusion of the relapse costs.

              Case selection and restrictions recommended to patients with hyperthyroidism in South America.

              Data from South America related to the use of radioiodine therapy indicate that radioiodine is prescribed only by physicians with special training and a license. A thyroid dose of 131I > 29 mCi requires hospitalization of the patient. Members of the Latin American Thyroid Society (LATS) (235 physicians) were surveyed by a questionnaire on their management of Graves' disease, and the survey procedure was the same used by the other thyroid societies. Thyroid uptake/scintigraphy was carried out by 60% of respondents and 131I was the isotope most used (chosen by 95% of respondents). Serum total T4 and T3 were requested by 97%, of LATS members whereas measurement of free T4 and TSH was employed less frequently (27% and 46.3%, respectively). The therapy of choice for 83% of responding members was antithyroid drugs. Radioiodine was chosen by 15.3% of respondents. For most respondents, the aim of 131I therapy was to restore euthyroidism. It was based on goiter size and thyroid uptake and administered in a single dose. For the radioiodine therapy, 55.5% of the respondents did not add any other medical treatment. The remaining group used antithyroid drugs before 131I (50%), and 77% employed it after the dose. There is a general consensus to provide the 131I treatment only to patients > 18 years of age. 131I was overwhelmingly (64.2% versus 34% of drug therapy) the therapy seen as most appropriate for patients with recurrence or old age. The predominant use of antithyroid drugs for therapy of Graves' disease in South America was similar to that in Europe and Japan but different from the practice in North America.
