While tachycardia is a known adverse effect of CSA, bradycardia remains a phenomenon rarely described in the literature.<\/jats:p>\n                  <jats:p>We conducted a retrospective evaluation of the incidence of bradycardia in patients after alloHSCT treated with CSA between January 2020 and February 2023 at our center.<\/jats:p>\n                  <jats:p>Out of 206 patients, sinus bradycardia following the administration of CSA was observed in 6 (2.9%), comprising 3 women and 3 men, with the median age of 55 years (range: 20-65). The underlying diseases were myeloid malignancies in 4 and aggressive lymphoma in 2 patients. The patients received grafts from a matched unrelated (n=5) or a haploidentical family donor (n=1) following various conditioning regimens. Coexisting cardiovascular disorders were found in 5 of the 6 patients. All patients experienced symptomatic bradycardia within 1-4 days (median 2 days) after CSA introduction, which persisted until CSA withdrawal. One patient required treatment with atropine. All patients continued their immunosuppressive therapy with tacrolimus, which was well-tolerated Our study indicates CSA as a causative factor of sinus bradycardia in a small percentage of alloHSCT patients receiving CSA as graft-versus host disease (GvHD) prophylaxis. Importantly, these patients did not experience any cardiac complications when switched to tacrolimus. Although further research on the effects of CSA on heart automatation is needed, our single-center experience can help prompt diagnosis and therapeutic intervention in daily clinical practice.<\/jats:p>","DOI":"10.46989\/001c.94362","type":"journal-article","created":{"date-parts":[[2024,3,4]],"date-time":"2024-03-04T00:49:22Z","timestamp":1709513362000},"source":"Crossref","is-referenced-by-count":0,"title":["Sinus bradycardia as a rare adverse event in patients receiving cyclosporine A after allogeneic hematopoietic stem cell transplantation."],"prefix":"10.46989","volume":"6","author":[{"given":"Magdalena","family":"Karasek","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01qpw1b93","id-type":"ROR","asserted-by":"publisher"}],"name":"Wroclaw Medical University","department":["Department of Haematology, Blood Neoplasms and Bone Marrow Transplantation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maciej","family":"Majcherek","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01qpw1b93","id-type":"ROR","asserted-by":"publisher"}],"name":"Wroclaw Medical University","department":["Department of Haematology, Blood Neoplasms and Bone Marrow Transplantation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bart\u0142omiej","family":"Kuszczak","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01qpw1b93","id-type":"ROR","asserted-by":"publisher"}],"name":"Wroclaw Medical University","department":["Department of Haematology, Blood Neoplasms and Bone Marrow Transplantation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agnieszka","family":"Szeremet","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01qpw1b93","id-type":"ROR","asserted-by":"publisher"}],"name":"Wroclaw Medical University","department":["Department of Haematology, Blood Neoplasms and Bone Marrow Transplantation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"Chyrko","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00yae6e25","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Wroc\u0142aw"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Wr\u00f3bel","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01qpw1b93","id-type":"ROR","asserted-by":"publisher"}],"name":"Wroclaw Medical University","department":["Department of Haematology, Blood Neoplasms and Bone Marrow Transplantation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Czy\u017c","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01qpw1b93","id-type":"ROR","asserted-by":"publisher"}],"name":"Wroclaw Medical University","department":["Department of Haematology, Blood Neoplasms and Bone Marrow Transplantation"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"26435","published-online":{"date-parts":[[2024,3,4]]},"reference":[{"issue":"6","key":"ref1","doi-asserted-by":"publisher","first-page":"1258","DOI":"10.1161\/01.hyp.35.6.1258","article-title":"Study of arterial and autonomic effects of cyclosporine in humans","volume":"35","author":"Daniela Lucini","year":"2000","journal-title":"Hypertension","ISSN":"https:\/\/id.crossref.org\/issn\/0194-911X","issn-type":"print"},{"issue":"7","key":"ref2","doi-asserted-by":"publisher","first-page":"732","DOI":"10.1097\/00007611-200107000-00021","article-title":"Gout, Bradycardia, and Hypercholesterolemia After Renal Transplantation","volume":"94","author":"STEPHEN P.
