Öğe Effects of Antithymocyte Globulin, Basiliximab, and Induction-Free Treatment in Living Donor Kidney Transplant Recipients on Tacrolimus-Based Immunosuppression(Baskent Univ, 2024) Sonmez, Ozge; Ozcan, Seyda Gul; Karaca, Cebrail; Atli, Zeynep; Dincer, Mevlut Tamer; Trabulus, Sinan; Seyahi, NurhanObjectives: Induction treatment in renal transplant is associated with better graft survival. However, intensified immunosuppression is known to cause unwanted side effects such as infection and malignancy. Furthermore, the effects of the routine use of immunosuppressants in low -risk kidney transplant recipients are still not clear. In this study, we assessed the first -year safety and efficacy of induction treatment. Materials and Methods: We examined first living donor kidney transplant patients who were on tacrolimusbased immunosuppression therapy. We formed 3 groups according to the induction status: antithymocyte globulin induction, basiliximab induction, and no induction. We collected outcome data on delayed graft function, graft loss, creatinine levels, estimated glomerular filtration rates, acute rejection episodes, hospitalization episodes, and infection episodes, including cytomegalovirus infection and bacterial infections. Results: We examined a total of 126 patients (age 35 +/- 12 years; 65% male). Of them, 25 received antithymocyte globulin, 52 received basiliximab, and 49 did not receive any induction treatment. We did not observe any statistically significant difference among the 3 groups in terms of acute rejection episodes, delayed graft function, and first -year graft loss. The estimated glomerular filtration rates were similar among the groups. Overall bacterial infectious complications and cytomegalovirus infection showed similar prevalence among all groups. Hospitalization was less common in the induction -free group. Conclusions: In low -risk patients, induction -free regimens could be associated with a better safety profile without compromising graft survival. Therefore, induction treatment may be disregarded in first living donor transplant patients who receive tacrolimusbased triple immunosuppression treatment.Öğe Sarcopenia, an overlooked diagnosis in kidney transplant recipients(Dustri-Verlag Dr Karl Feistle, 2024) Ozcan, Seyda Gul; Sonmez, Ozge; Atli, Zeynep; Karaca, Cebrail; Alagoz, Selma; Akman, Zafer; Koroglu, Ali EgemenMost studies of sarcopenia in renal transplant recipients (RTRs) have been hampered by a lack of standardization in the definitions of sarcopenia. In this study, we aimed to investigate the prevalence of sarcopenia and the associated factors in RTRs using the recently proposed criteria of the European Working Group on Sarcopenia in Older People 2018 (EWGSOP2), which included a standardized definition of sarcopenia. We examined 93 consecutive adult RTRs, 46 chronic kidney disease patients, and 46 healthy controls. We assessed the muscle strength with a hand grip test using a dynamometer and with a chair stand test. We used bioimpedance analysis to estimate appendicular skeletal mass using the Sergi formula. Finally, we conducted a 2-minute walking test to assess endurance. Sarcopenia and probable sarcopenia were determined according to the revised criteria of the EWGSOP2. Probable sarcopenia was found in 29 RTR patients (31.2%), of them 14 (15.1%) were diagnosed with sarcopenia. Multivariate logistic regression analysis showed that presence of diabetes mellitus, increased uric acid level, and statin use were risk factors for probable sarcopenia. On the other hand, longer dialysis vintage was a risk factor for sarcopenia in RTRs. We found that probable sarcopenia and sarcopenia were highly prevalent in our relatively young RTRs. We recommend active screening for the presence of sarcopenia in RTRs, especially in the cadaveric ones. Furthermore, caution seems warranted regarding the myopathic side effects in RTRs who use statins.Öğe SARCOPENIA: AN OVERLOOKED DIAGNOSIS IN KIDNEY TRANSPLANT RECIPIENTS(Oxford Univ Press, 2022) Ozcan, Seyda Gul; Sonmez, Ozge; Akman, Zafer; Karaca, Cebrail; Atli, Zeynep; Trabulus, Sinan; Seyahi, Nurhan[No abstract available]
