20.500.12556/RUL-144752 Peripheral blood lymphocyte subtypes in dogs with different stages of myxomatous mitral valve disease Background: Data on alterations in peripheral blood lymphocyte (PBL) subtypes in dogs with myxomatous mitral valve disease (MMVD) is lacking. Objectives: To investigate PBL subtypes and their correlation with parameters of inflammation and MMVD progression markers in dogs with different stages of MMVD. Animals: Seventy-eight client-owned dogs: 65 with MMVD (American College of Veterinary Internal Medicine [ACVIM] classification stages B2, C, and D) and 13 healthy controls. Methods: Prospective cross-sectional study. Complete cardiac assessment, flow cytometry (T lymphocytes [CD3+], their subtypes [CD3+CD4+, CD3+CD8+, CD3+CD4+CD8+, CD3+CD4−CD8−], and B lymphocytes [CD45+CD21+]) and measurement of N-terminal pro B-type natriuretic peptide, cardiac troponin I, and C-reactive protein concentrations were performed. Results: The percentage of CD3+CD4+ lymphocytes was significantly lower in stable ACVIM C patients (P = .01) and unstable ACVIM C and D patients (P = .003), the percentage of CD3+CD8+ lymphocytes was significantly higher in stable ACVIM C patients (P = .01) and unstable ACVIM C and D patients (P = .01), CD3+CD8+ lymphocyte concentration was significantly higher in unstable ACVIM C and D patients (P = .05), and the CD3+CD4+/CD3+CD8+ ratio was significantly lower in stable ACVIM C patients (P = .01) and unstable ACVIM C and D patients (P = .01) compared with healthy controls. Conclusions and Clinical Importance: The percentages of CD3+CD4+ and CD3+CD8+ PBL and CD4+/CD8+ ratio were altered in MMVD dogs with congestive heart failure (ACVIM C, D), but not in ACVIM B2, suggesting involvement of these PBL subtypes in the pathogenesis of congestive heart failure in dogs with MMVD. canine CD21 B lymphocytes CD3 T lymphocytes CD4 T helper lymphocytes CD45 CD8 cytotoxic T lymphocytes congestive heart failure degenerative mitral valve disease flow cytometry heart diseases dogs true false true Angleški jezik Ni določen Članek v reviji 2023-03-10 12:04:27 2023-03-10 12:04:27 2023-03-11 03:36:47 0000-00-00 00:00:00 2021 0 0 Str. 2112-2122 iss. 5 Vol. 35 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 636.7.09:616.1 1939-1676 10.1111/jvim.16207 69808131 Veterinary_Internal_Medicne_-_2021_-_Druzhaeva_-_Peripheral_blood_ly.pdf Veterinary_Internal_Medicne_-_2021_-_Druzhaeva_-_Peripheral_blood_ly.pdf 1 55BD9208E41279DCE53DE6C505E84088 1baa50f42284b866e2fb3eadabf3585779b9da94c9cfbf46ced63781b0a27345 f24edc37-bf55-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167277 https://onlinelibrary.wiley.com/doi/10.1111/jvim.16207 1 4853a6e1-bf33-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167244 Veterinarska fakulteta Medicinska fakulteta 0 0 0
