ABSTRACT
ABSTRACT Objective: Fibrous dysplasia (FD) is a rare bone disorder that can involve any part of the skeleton, leading to bone pain, deformities, and fractures. Treatment with intravenous bisphosphonates has been used with variable results. Therefore, we aimed to evaluate the effects of zoledronic acid (ZA) therapy in patients with monostotic or polyostotic FD. Subjects and methods: The medical records of thirteen patients with FD evaluated between 2015 and 2020 were retrospectively analyzed. In the subgroup of patients treated with ZA (n = 7), data on pain relief, changes in bone turnover markers (BTMs), and adverse events following ZA infusions were retrieved. Moreover, radiological changes in response to treatment were recorded in patients who underwent radiological follow-up. Results: Of the patients, 5 (38%) presented with monostotic whereas 8 (62%) had polyostotic FD. Bone pain was a common finding (69%), and most patients (62%) exhibited elevated baseline BTMs. Partial or complete pain relief was reported in 6 of 7 patients treated with ZA. BTMs, especially C-telopeptide of type I collagen (CTX), significantly decreased after therapy (change rate: −61.8% [IQR −71, −60%]), and median CTX levels were significantly lower than at baseline (0.296 ng/mL [0.216, 0.298] vs. 0.742 ng/mL [0.549, 0.907], respectively; P = 0.04). No radiological improvement was observed in cases with radiological follow-up (n = 3). No serious adverse effects of ZA were reported. Conclusion: ZA treatment was well tolerated and provided beneficial effects in relieving bone pain and reducing BTMs, especially CTX. Our data reinforce the role of ZA in the treatment of FD-related bone pain.
ABSTRACT
Os Centros de Medicação de Alto Custo (CEDMAC) da Secretaria de Saúde do Estado de São Paulo foram instituídos por projeto em parceria com Hospital das Clínicas da Faculdade de Medicina da USP, patrocinado pela Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP), visando à formação de rede estadual para atendimento integral dos pacientes indicados ao uso de agentes imunobiológicos nas doenças reumatológicas. O CEDMAC do Hospital de Clínicas da Universidade Estadual de Campinas (HC-Unicamp), implementado pela Disciplina de Reumatologia da Faculdade de Ciências Médicas, identificou a necessidade de padronização das condutas da equipe multidisciplinar, frente à especificidade da assistência, verificando a importância da descrição, em formato de manual, dos seus processos de trabalho e técnicas. O objetivo do estudo foi apresentar a metodologia de construção do manual do CEDMAC/HC-Unicamp como ferramenta institucional, visando à qualidade assistencial e administrativa. A metodologia para elaboração dos manuais no HC-Unicamp, desde 2008, tem como premissas ser participativo, multidisciplinar, focado em processos de trabalho, integrado às normas institucionais, com descrição objetiva e didática, formato padronizado e divulgação eletrônica. O Manual do CEDMAC/HC-Unicamp foi construído em dez meses, com o envolvimento de toda equipe multidisciplinar, tendo 19 capítulos sobre processos de trabalho e técnicas, além dos relativos à estrutura organizacional e anexos. Publicado no portal eletrônico dos Manuais HC, em julho de 2012, como e-book, com registro ISBN 978-85-63274-17-5. O Manual tem sido valioso instrumento na orientação dos profissionais da área nas atividades assistenciais, de ensino e pesquisa.
The Centers for High Cost Medication (Centros de Medicação de Alto Custo, CEDMAC), Health Department, São Paulo were instituted by project in partnership with the Clinical Hospital of the Faculty of Medicine, USP, sponsored by the Foundation for Research Support of the State of São Paulo (Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP) aimed at the formation of a statewide network for comprehensive care of patients referred for use of immunobiological agents in rheumatological diseases. The CEDMAC of Hospital de Clínicas, Universidade Estadual de Campinas (HC-Unicamp), implemented by the Division of Rheumatology, Faculty of Medical Sciences, identified the need for standardization of the multidisciplinary team conducts, in face of the specificity of care conducts, verifying the importance of describing, in manual format, their operational and technical processes. The aim of this study is to present the methodology applied to the elaboration of the CEDMAC/HC-Unicamp Manual as an institutional tool, with the aim of offering the best assistance and administrative quality. In the methodology for preparing the manuals at HC-Unicamp since 2008, the premise was to obtain a document that is participatory, multidisciplinary, focused on work processes integrated with institutional rules, with objective and didactic descriptions, in a standardized format and with electronic dissemination. The CEDMAC/HC-Unicamp Manual was elaborated in 10 months, with involvement of the entire multidisciplinary team, with 19 chapters on work processes and techniques, in addition to those concerning the organizational structure and its annexes. Published in the electronic portal of HC Manuals in July 2012 as an e-Book (ISBN 978-85-63274-17-5), the manual has been a valuable instrument in guiding professionals in healthcare, teaching and research activities.
