    Effects of Body Mass Index Changes In Pediatric Kidney Transplant Patients
    (Elsevier Inc., 2023) Taner, S.; Goktepe, B.; Zaman, E.I.; Keskinoğlu, A.; Kabasakal, C.; Bulut, I.K.; Sezer, O.
    Background: The negative effects of pretransplant obesity and post-transplant body mass index (BMI) increase on graft survival have been reported in recent years. The aim of this study is to evaluate the effects of BMI changes on post-transplant graft function, lipid profile, and blood pressure. Methods: The study included 133 pediatric patients transplanted between 1994 and 2019 in Ege University. BMI Z-scores (BMIZs) were calculated according to age and sex before and after transplantation using the World Health Organization criteria. Patients with BMIZs >+1 standard deviation (SD) were defined as overweight, and those with BMIZs >+2 SD were defined as obese: Group 1: Obese or overweight before transplantation; Group 2: Thin or normal weight before and 2 years after transplantation; and Group 3: Thin or normal weight before transplantation and obese or overweight 2 years after transplantation. Results: At the time of transplantation 8% of the patients were overweight, and 1% were obese. Overweight and obesity statistically significantly increased (31.6%) 2 years after renal transplantation (P =.001). Obese and overweight patients have lower high-density lipoprotein levels and were younger at the time of transplantation. Graft functions, lipid levels, and blood glucose levels of the groups were similar (P >.05). The only significant difference between the groups was that Group 1 patients were younger than Group 2. Conclusions: Obesity develops at a significant rate in pediatric patients after renal transplantation. In this study, we could not demonstrate negative effects of obesity and being overweight in terms of post-transplant graft function, lipid profile, blood glucose, and blood pressure. © 2022 Elsevier Inc.

    Quality of Life and Psychological Well-Being in Children and Adolescents After Renal Transplantation
    (Elsevier Inc., 2023) Demir, M.H.B.; Taner, S.; Demir, H.B.; Taşdemir, A.I.; Keskinoğlu, A.; Bulut, I.K.; Sezer, T.O.
    Background: Kidney transplantation is the predominant treatment option in patients with end-stage renal disease. The aim of this study was to evaluate the effect of the presence of a psychiatric disorder on the quality of life in children and adolescents after kidney transplantation. Methods: A total of 43 patients aged 6 to 18 years were included in the study. All participants and their parents were asked to complete the Pediatric Quality of Life Inventory (PedsQL), and families only, the Strengths and Challenges Questionnaire. Psychiatric symptoms and disorders of the patients were evaluated according to the Schedule for Mood Disorders and Schizophrenia for School-Age Children/Now and Lifetime Turkish Version. Patients were divided into 2 groups according to psychiatric symptoms and disorders. Results: The most common psychiatric disorder was attention deficit and hyperactivity disorder (26%). The questionnaires filled out by the patients revealed a lower Total PedsQL Score (P =.003), PedsQL Physical Functionality Score (P =.019), and PedsQL Social Functioning Score (P =.016) in patients with psychiatric disorders. When the parents filled out the questionnaires, the Total PedsQL Score was similar in both groups. The PedsQL Emotional Functionality Score (P =.001) and PedsQL School Functionality Score (P =.004) were significantly lower in patients with psychiatric disorders. The Strengths and Difficulties Questionnaire revealed significantly higher total (P =.014) and hyperactivity/inattention subscale scores (P =.001) in those with a psychiatric disorder. Conclusions: Psychiatric disorders in kidney transplant patients adversely affect the quality of life. © 2023 Elsevier Inc.

    Role of Systemic Inflammatory Markers in Pediatric Kidney Transplantation
    (Elsevier Inc., 2023) Taner, S.; Goktepe, B.; Zaman, E.I.; Asci, G.; Bulut, I.K.; Toz, H.; Sarsik, B.
    Background: Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), systemic immune-inflammation index (SII = N × P/L), and neutrophil percentage-albumin ratio (NPAR) have become accepted markers of inflammation in recent years. These indices are used as indicators of disease activity, mortality, and morbidity in many diseases. This study evaluated the relationship between inflammatory indices and graft function in pediatric kidney transplant recipients. Methods: Medical records of pediatric patients who underwent kidney transplantation at Ege University between 1995 and 2020 were reviewed retrospectively. Demographic, clinical, and laboratory data were recorded during the third month, first year, and fifth year of transplantation and at the last visit. Results: The median age of the 119 patients (60 boys/59 girls) at the time of transplantation was 154 months, and the median follow-up period was 101 months. According to Spearman correlation analysis, patients' final creatinine levels were positively correlated with NLR (r = 0.319), PLR (r = 0.219), SII (r = 0.214), and NPAR (r = 0.347) of the last visit; final estimate glomerular filtration rate levels were negatively correlated with NLR (P = .010, r = ?0.250) and NPAR (P = .004, r = ?0.277). The median NPAR of the patients with chronic allograft dysfunction at the last visit was found to be statistically significantly higher than without (P = .032). Conclusion: NLR, PLR, SII, and NPAR values are correlated with creatinine levels after 5 years of kidney transplantation. The NPAR and final creatinine levels had the highest correlation coefficient among these inflammatory markers. These results suggest that inflammatory markers, especially NPAR, may be a candidate to be an indicator of ongoing inflammation in the graft. © 2023 Elsevier Inc.
