Item The relationship between body mass index and renal length in obese children(2020) Parmaksiz, Gonul; Kekec, Senay Demir; Cengiz, Nurcan Dinler; Noyan, Aytul; 0000-0003-2373-1837; 31997076; AAD-5713-2021; AAM-2935-2021Background Obesity in the pediatric population is a severe public health problem and is associated with various comorbidities. Renal length is an important clinical parameter for the diagnosis and follow-up of renal diseases. The aim of this study was to determine the relationship between renal length (measured ultrasonographically) and body mass index (BMI) in obese children, and to develop nomograms for renal length according to BMI. Methods Renal ultrasound was performed in 368 children without renal disease. Each child's age, gender, weight, height, and BMI (kg/m(2)) were recorded. The children were divided into three groups according to BMI percentiles: obese group: BMI >= 95th percentile; overweight group: BMI 85th-94th percentile; normal weight group: BMI 5th-84th percentile. Results Weight, height, BMI, and right and left renal length differed significantly between the three groups (p = 0.001). There were significant correlations between renal length with age, weight, height, and BMI. Measurement of renal length was independently associated with BMI, age, and height. BMI was used to create renal length nomograms for obese children, based on multiple regression analysis (R-2 = 0.32 and p = 0.0001). Mean renal length was highest in the obese group (96.9 +/- 13.4 mm) and lowest in the normal weight group (88.3 +/- 12.9 mm). Conclusions Ultrasonographic measurement of the renal length according to BMI in children can be a useful method in evaluating these children. Smaller-than-normal kidneys can easily remain undiagnosed in obese and overweight children and this nomogram offers an additional method to evaluate the renal size in obese children.Item Evaluation of non-infectious complications of peritoneal dialysis in children: a multicenter study(2020) Aksoy, Gulsah Kaya; Ekim, Mesiha; Bakkaloglu, Sevcan A.; Coskun, Seda; Delibas, Ali; Conkar, Secil; Yilmaz, Dilek; Kara, Aslihan; Saygili, Seha K.; Buyukkaragoz, Bahar; Yildirim, Zeynep Y.; Comak, Elif; Gurgoze, Metin K.; Sever, Lale; Noyan, Aytul; Bayazit, Aysun K.; Dusunsel, Ruhan; 32728843; AAD-5713-2021Background Peritoneal dialysis (PD) is the most common kidney replacement therapy in children. Complications associated with PD affect treatment success and sustainability. The aim of this study was to investigate the frequency of PD-related noninfectious complications and the predisposing factors. Methods Retrospective data from 11 centers in Turkey between 1998 and 2018 was collected. Non-infectious complications of peritoneal dialysis (NICPD), except metabolic ones, in pediatric patients with regular follow-up of at least 3 months were evaluated. Results A total of 275 patients were included. The median age at onset of PD and median duration of PD were 9.1 (IQR, 2.5-13.2) and 7.6 (IQR, 2.8-11.9) years, respectively. A total of 159 (57.8%) patients encountered 302 NICPD within the observation period of 862 patient-years. The most common NIPCD was catheter dysfunction (n = 71, 23.5%). At least one catheter revision was performed in 77 patients (28.0%). Longer PD duration and presence of swan neck tunnel were associated with the development of NICPD (OR 1.191; 95% CI 1.079-1.315, p = 0.001 and OR 1.580; 95% CI 0.660-0.883, p = 0.048, respectively). Peritoneal dialysis was discontinued in 145 patients; 46 of whom (16.7%) switched to hemodialysis. The frequency of patients who were transferred to hemodialysis due to NICPD was 15.2%. Conclusions Peritoneal dialysis-related non-infectious complications may lead to discontinuation of therapy. Presence of swan neck tunnel and long duration of PD increased the rate of NICPD. Careful monitoring of patients is necessary to ensure that PD treatment can be maintained safely.
