Background 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.
HPSE2 Mutations in Urofacial Syndrome, Non-Neurogenic Neurogenic Bladder and Lower Urinary Tract Dysfunction
(2015) Bulum, Burcu; Ozcakar, Z. Birsin; Duman, Duygu; Cengiz, Filiz Basak; Kavaz, Asli; Burgu, Berk; Baskin, Esra; Cakar, Nilgun; Soygur, Tarkan; Ekim, Mesiha; Tekin, Mustafa; Yalcinkaya, Fatos; 0000-0003-4361-8508; 25924634; B-5785-2018
Background: Urofacial syndrome (UFS) is characterised by congenital bladder dysfunction accompanied by a characteristic abnormal grimace upon smiling and crying. In recent years, biallelic mutations of HPSE2 and LRIG2 have been reported in UFS patients. Non-neurogenic neurogenic bladder (NNNB) has a bladder identical to UFS without typical facial features. The aim of this study was to analyse HPSE2 mutations in patients with UFS and NNNB or severe lower urinary tract dysfunction (LUTD) without abnormal facial expression. Methods: Patients with UFS, NNNB and severe LUTD were enrolled in the study. We examined a total of 35 patients from 33 families. There were seven UFS patients from five different families, 21 patients with NNNB and seven with LUTD. HPSE2 gene mutation analysis was performed using the polymerase chain reaction protocol followed by Sanger sequencing in these patients. Results: A twin pair with UFS was found to be homozygous for c.457C>T (p.Arg153*) mutation. No other pathogenetic variant was detected. Conclusion: HPSE2 mutations were found in one UFS family but not detected in patients with NNNB and severe LUTD. Considering the increasingly recognised cases of NNNB that were diagnosed in early childhood period, genetic factors appear to be responsible. Thus, further genetic studies are needed to discover novel associated gene variants in these bladder anomalies. (C) 2015 S. Karger AG, Basel
Utility Of Continuous Performance Test (MOXO-CPT) In Children With Pre-Dialysis Chronic Kidney Disease, Dialysis And Kidney Transplantation
(2022) Buyukkaragoz, Bahar; Soysal Acar, A. Sebnem; Ekim, Mesiha; Bayrakci, Umut Selda; Bulbul, Mehmet; Caltik Yilmaz, Aysun; Bakkaloglu, Sevcan A.; 000829126000001
Background Children with chronic kidney disease and on kidney replacement therapy may have neurocognitive and psychosocial disorders. Although kidney transplantation improves quality of life, psychological problems may exist in children who undergo kidney transplantation. Herein, we aimed to investigate attention-deficit hyperactivity disorder-like symptoms with MOXO-continuous performance test in children with pre-dialysis chronic kidney disease, dialysis and kidney transplantation. Methods The MOXO-continuous performance test measures four domains of attention-deficit hyperactivity disorder-like symptoms, including attention, timeliness, hyperactivity and impulsivity. Patients with at least three scores < - 1.5 standard deviations were considered as positive to MOXO-continuous performance test. Test scores of the pre-dialysis chronic kidney disease, dialysis (divided into peritoneal dialysis and hemodialysis subgroups) and kidney transplantation groups were compared. Correlations of test scores with the patient's clinical and laboratory characteristics and effects of hospitalizations and schooling were assessed. Results Seventy-two patients aged 13.3 +/- 3.4 years (23 with kidney transplantation, 23 on dialysis and 26 with pre-dialysis chronic kidney disease) were evaluated. Overall MOXO-continuous performance test positivity was 29%. No differences were detected between the three groups concerning total or z scores. Attention and timeliness z scores were significantly higher in females (p = 0.004 and p = 0 .008 , respectively). Age was positively correlated to attention and timeliness total scores (p = 0.000, r = 0.445 and p = 0.004, r = 0.243, respectively), and inversely correlated to hyperactivity total scores (p = 0.000, r = - 0.415). Conclusions Prevalence of attention-deficit hyperactivity disorder-like symptoms in the study population was much higher than that of pediatric attention-deficit hyperactivity disorder. We believe that the MOXO-continuous performance test is a valid supportive measure for evaluation of attention-deficit hyperactivity disorder diagnosis in children with various stages of chronic kidney disease or on kidney replacement therapy.
