ObjectiveThe aim of the study was to analyse the health-related quality of life (HRQoL) in Polish children with chronic kidney disease (CKD) dependant on the CKD stage, treatment modality and selected social life elements in families of the patients. Furthermore, potential differences between self-report and parent/proxy reports and the factors influencing them were assessed.MethodsA total of 203 CKD children (on haemodialysis (HD), peritoneal dialysis (PD) and conservative treatment (CT)) and their 388 parent/proxies were enrolled into a cross-sectional national study. The demographic and social data were evaluated. We used the Paediatric Quality of Life Inventory 4.0 Generic Core Scales to assess the HRQoL in children.ResultsHealth-related quality of life scores for all CKD groups were significantly lower in all domains compared with population norms, the lowest one being in the HD group. In CT children, HRQoL did not depend on the CKD stage. Both parents assessed the HRQoL of their children differently depending on their involvement in the care. There are differences between the HRQoL scores of the children and their parents.ConclusionThe HRQoL in children with CKD is lower than in healthy children. This is already observed in the early stages of the disease. The disease itself influences the child’s mental state. Children on HD require special support on account of the lowest demonstrated overall HRQoL. Children’s lower rating of the quality of life observed by their parents may render the patients unmotivated and adversely affect their adjustment to life in later years. It may also create conflicts between the parents and the children.

Little information exists regarding the efficacy, modifiers, and outcomes of anemia management in children with CKD or ESRD. We assessed practices, effectors, and outcomes of anemia management in 1394 pediatric patients undergoing peritoneal dialysis (PD) who were prospectively followed in 30 countries. We noted that 25% of patients had hemoglobin levels below target (,10 g/dl or ,9.5 g/dl in children older or younger than 2 years, respectively), with significant regional variation; levels were highest in North America and Europe and lowest in Asia and Turkey. Low hemoglobin levels were associated with low urine output, low serum albumin, high parathyroid hormone, high ferritin, and the use of bioincompatible PD fluid. Erythropoiesis-stimulating agents (ESAs) were prescribed to 92% of patients, and neither the type of ESA nor the dosing interval appeared to affect efficacy. The weekly ESA dose inversely correlated with age when scaled to weight but did not correlate with age when normalized to body surface area. ESA sensitivity was positively associated with residual diuresis and serum albumin and inversely associated with serum parathyroid hormone and ferritin. The prevalence of hypertension and left ventricular hypertrophy increased with the degree of anemia. Patient survival was positively associated with achieved hemoglobin and serum albumin and was inversely associated with ESA dose. In conclusion, control of anemia in children receiving long-term PD varies by region. ESA requirements are independent of age when dose is scaled to body surface area, and ESA resistance is associated with inflammation, fluid retention, and hyperparathyroidism. Anemia and high ESA dose requirements independently predict mortality.

Previously published studies have indicated that gastroesophageal reflux (GER) disease is common in pediatric patients with cystic fibrosis. The aim of the present study was to get insight into the incidence of GER and to characterize the nature of reflux episodes in children with cystic fibrosis. This was a multicenter, prospective study of children with cystic fibrosis older than 18 months. Forty four consecutive patients (22 boys, mean age 10.4 ± 3.6, range 3.0-17.8 years) were enrolled into the study. All patients underwent 24 h pH-impedance monitoring. GER were classified according to the widely recognized criteria as an acid, weakly acid, weakly alkaline, or proximal. The pH-impedance trace was considered abnormal when acid exposure was >6 %. GER was diagnosed in 24/44 (54.5 %) children. A total of 1585 (median 35, range 7-128) reflux episodes were detected; 1199 (75.6 %) were acidic, 382 (24.1 %) weakly acidic, and 4 (0.3 %) weakly alkaline. Six hundred and ninety-one (43.6 %) reflux episodes reached the proximal esophagus. In 14/44 patients typical GER symptoms were present. We conclude that the incidence of GER in children with cystic fibrosis is very high. In the majority of patients typical GER symptoms are absent. Therefore, diagnostic procedures should be considered, regardless of lacking symptoms. Although acid reflux episodes predominate in children with cystic fibrosis, classical pH-metry may not constitute a sufficient diagnostic method in this population because of a relatively high number of proximal reflux episodes. Such episodes also indicate an increased risk for aspiration. The pH-impedance diagnostic measurement is advocated when suspecting GER in children with cystic fibrosis.

BackgroundThe aim of this study was to analyze psychosocial aspects of chronic kidney disease (CKD) in children treated with automated peritoneal dialysis (APD).MethodsThe study assessed 41 children > 2  (range 2.1–18) years of age and their parents. Data concerning the illness and sociodemographic parameters were collected. Patients completed the Paediatric Quality of Life Inventory (PedsQL) and their parents the PedsQL-proxy version, General Health Questionnaire (GHQ-12), Berlin Social Support Scales (BSSS), and Caregiver’s Burden Scale (CBS).ResultsParents rated their children’s overall health-related quality of life (QoL) as well as their physical and emotional functioning lower than the patients themselves. The majority of primary caregivers had a medium level of the total burden index in the CBS and higher values in the scales need for support and perceived available support than in the received support (BSSS). In the GHQ-12, 51.2 % of primary caregivers had scores >2 points, which indicated the possible occurrence of abnormal mental functioning.ConclusionsFinancial support for patients’ families is necessary. Parents who provide primary care to children on PD require, above all, emotional support and assistance in self-fulfilment. More than half of them may have impaired mental function. There is the strong need to provide continuous psychological care for caregivers. Differences in perception of the children’s activity in varied areas by the patients themselves and their caregivers may contribute to further problems within families.

The assessment of QoL in pediatric patients would allow for the earliest possible identification of their nonsomatic problems and irregularities. This could, consequently, contribute to improving QoL in both children with chronic kidney disease and their families.
