Treatment duration, age, and JC virus (JCV) antibody titer could be associated with the occurrence of fingolimod-induced PML.45,46 Cases of PML have been reported with anti-CD20 monoclonal antibodies (15 cases with rituximab and 5 cases with ocrelizumab); however, most of these cases could be attributed to previous natalizumab or fingolimod therapy. PML, progressive multifocal leukoencephalopathy; TNF, tumor necrosis factor; TB, tuberculosis; VZV, varicella-zoster virus. The European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group for Infections in Compromised Hosts Consensus have reviewed articles and made recommendations to instruct Phthalylsulfacetamide clinicians on the strategies to prevent and manage infections associated with biologic and targeted immunomodulators.8C13 In this review, we aim to focus on evidence-based strategies according to the latest guidelines to provide practitioners guidance regarding screening, chemoprophylaxis, vaccination, and management of infections in patients on biologic and targeted immunomodulators. Methods We conducted a literature search in databases including Scopus, Medline, Embase, Cochrane Database Systematic Reviews and Google Scholar from January 2007 to August 2019 using the search terms related to each of the agents along with infection, vaccination, screening, prophylaxis, monitoring, immunization, immune response, treatment, and management. Polyclonal antibodies (e.g., anti-thymocyte globulin, rozrolimupab), and monoclonal antibodies that lack prominent immunosuppressive effects (e.g., trastuzumab) were beyond the scope of our review and are not considered here. We included articles and guidelines from the latest updates of ESCMID, The Infectious Diseases Society of America (IDSA), The European League Against Rheumatism (EULAR), Phthalylsulfacetamide National Comprehensive Cancer Network (NCCN), American College of Rheumatology (ACR), American College of Gastroenterology (ACG), The American Association for the Study of Liver Diseases (AASLD), The Canadian Dermatology Association (CDA), European Conference on Infections in Leukaemia (ECIL), The Advisory Committee on Immunization Practices (ACIP), The American Society of Transplantation (AST), European Conference on Infections in Leukaemia (ECIL), The German Society of Hematology and Medical Oncology and the International Consensus Guidelines on the Management of Cytomegalovirus. 8C29 We also included recommendations from Uptodate online, the relevant review articles, Phthalylsulfacetamide expert opinions, and European Medicines Agency (EMA) drug labels, especially on subjects that the guidelines do not offer an opinion. The recommendations Rabbit Polyclonal to VEGFR1 regarding screening for infections, immunization, prevention, and monitoring of infections in patients candidates for biologic and targeted immunomodulators were finally categorized by the class of immunosuppressive agents. Results Of the relevant articles we found, data were obtained from 31 guidelines as well as consensus recommendations and 17 review papers. Comprehensive recommendations were not found on subjects such as prophylactic measures for prevention of pneumocystis pneumonia in biologic therapy of rheumatologic diseases, screening of infections for patients undergoing basiliximab induction, preventive measures to prevent infections associated with abatacept, immunization in patients undergoing treatment with new generations of anti-CD20 monoclonal antibodies and late onset neutropenia associated with anti-CD20 monoclonal antibodies. Such data were obtained from expert opinions, review articles, the EMA drug labels and clinical trials. The recommendations regarding screening, prophylaxis, monitoring, and immunization of infections associated with biologic and targeted immunomodulators are summarized in Tables 2C5.
