Background: Kidney transplantation is the preferred treatment modality for children with end-stage renal disease. In the adult population, migration-related modifiable factors were associated with low living donation rates; no such data are available on the pediatric population. This pilot study therefore compares donation modality, communication, knowledge, and attitudes/beliefs between families of immigrant and non-immigrant descent. Methods: Demographic and clinical characteristics of a cohort of children from 77 families of immigrant (32; 42%) and non-immigrant (45; 58%) descent who had undergone renal transplantation were assessed and related to donation modality at the Medical University of Vienna. In a representative subset, modifiable migration-related factors were assessed in a questionnaire-based study. Results: In immigrant families, information delay, limited communication, low knowledge levels, and self-reported conflicting beliefs were significantly more prevalent than in non-immigrants. The living kidney donation rate to children was high in both populations (immigrants: 63%, non-immigrants: 44%; p = 0.12). Living donation to children on dialysis was even significantly higher in immigrant families (immigrants: 13 out of 20; 57%, non-immigrants: 9 out of 33; 27%; p = 0.03). Conclusion: Contrary to expectations, migration-related disparities did not translate into decreased living donation rates in immigrant families, in particular to children on dialysis. Certain factors might therefore be less important for the living donation process in pediatric care structures and/or might be overcome by yet undefined protective factors. Larger pediatric studies including qualitative and quantitative methods are required to validate and refine current conceptual frameworks integrating the perspective of affected families.

Although brucellosis is a multi-systemic illness, terminal ileitis or colitis due to brucellosis is reported anecdotal in literature. Genitourinary manifestations of Brucella, namely epididymo-orchitis is very rare in childhood brucellosis. Herein, we present a case of brucellosis in a child with a rare combination of terminal ileitis and epididymo-orchitis not reported previously in the literature.

Background: There is a growing body of evidence showing that there is an association between oxidative damage and kidney injury in patients with nephrotic syndrome (NS). Dynamic thiol/disulphide homeostasis (DTDH) is an important antioxidant system. The aim of this study was to determine if DTDH could be used as a biomarker of antioxidant status in pediatric NS patients using a novel automated method. Methods: The study included 39 patients with NS and 40 healthy controls. The DTDH level was measured using a calorimetric and automated method developed by Erel and Neselioglu. In the NS group, DTDH was measured during first-attack episode, relapse, and remission. Results: The native thiol, total thiol, and disulphide levels were significantly lower, the native thiol/total thiol ratio was significantly lower, and the disulphide/native thiol and disulphide/total thiol ratios were significantly higher in the NS patients during relapse and first-attack episode than during remission and in the controls. In addition, the native thiol and total thiol levels, and the native thiol/total thiol ratio were significantly lower, and the disulphide/native thiol and disulphide/total thiol ratios were significantly higher in the NS group during remission than those in the control group. Conclusions: The present findings show that DTDH shifted toward disulphide formation in the NS patients, even during remission. A clearer understanding of the mechanism of this disruption to homeostasis in NS patients might lead to the development of novel therapeutic strategies.

AKI is an important condition in all hospitalized patients. More studies and interventions are needed on this topic to identify, treat and prevent AKI.
