However, residual therapeutic antibodies such as elotuzumab (IgG-κ), can compromise IFE evaluation when the affected immunoglobulins belong to the same IgG-κ subclass. We thus sought to develop a simple and rapid method to treat patient serum before IFE to distinguish the residual elotuzumab. Serum samples from patients receiving elotuzumab were treated with a predetermined amount of soluble signaling lymphocyte activation molecule F7 (SLAMF7) protein and then subjected to conventional IFE testing. We tested our method in samples from 12 patients. The IgG-κ band in IFE disappeared or shifted after elotuzumab treatment in four patients with no bone marrow minimal residual disease and normalized free light chain, whereas seven patients with any sign of residual MM showed a remaining IgG-κ band after treatment. One-hour incubation of samples with 6–9 molar excess soluble SLAMF7 before IFE was sufficient to distinguish residual elotuzumab in 11 of 12 samples. This simple method does not require special reagents, can be performed in most clinical laboratories, and enables differentiation between patients with a CR and those requiring further treatment.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer","subitem_publisher_language":"en"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s12185-021-03088-9","subitem_relation_type_select":"DOI"}}]},"item_9_source_id_7":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"0925-5710","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Chen, Shurui","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kiguchi, Toru","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Nagata, Yasuyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Tamai, Yotaro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Ikeda, Takeshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kajiya, Ryoko","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Ono, Takaaki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Sugiyama, Daisuke","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Nishikawa, Hiroyoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Akatsuka, Yoshiki","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-04-01"}],"displaytype":"detail","filename":"IJH_R1.pdf","filesize":[{"value":"554 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/2001637/files/IJH_R1.pdf"},"version_id":"cfe85530-516f-47e1-ac6e-489d9adf23c2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Elotuzumab","subitem_subject_scheme":"Other"},{"subitem_subject":"Immunofixation electrophoresis","subitem_subject_scheme":"Other"},{"subitem_subject":"Monoclonal antibody","subitem_subject_scheme":"Other"},{"subitem_subject":"Multiple myeloma","subitem_subject_scheme":"Other"},{"subitem_subject":"Therapeutic","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A simple method to distinguish residual elotuzumab from monoclonal paraprotein in immunofixation assays for multiple myeloma patients","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A simple method to distinguish residual elotuzumab from monoclonal paraprotein in immunofixation assays for multiple myeloma patients","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"17","path":["501"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-11-22"},"publish_date":"2021-11-22","publish_status":"0","recid":"2001637","relation_version_is_last":true,"title":["A simple method to distinguish residual elotuzumab from monoclonal paraprotein in immunofixation assays for multiple myeloma patients"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-01-16T05:14:12.810276+00:00"}
