Abstract Background: The specific etiology and mechanism of idiopathic nephrotic syndrome (INS) in children remain unclear, so we investigated the pathogenesis of INS by measuring the effects two specific miRNAs on Th2 cells in children with this disease. Methods: Flow cytometry was used to measure the levels of Th2 cells and a cytometric bead array was used to measure the levels of IgE, interleukin (IL) -4, and IL-13. RT-PCR was used to measure the levels of miR-24 and miR-27 in CD4+TCD25− cells. PBMCs were isolated using Ficoll density gradient centrifugation, and transfected with different mimic or inhibitor miRNAs. RT-PCR was used to measure the expression of different RNAs, and flow cytometry was used to determine the percentages of Th2 cells. Results: Children with active INS had higher percentages of Th2 cells than healthy controls (P<0.05), but there was no significant difference for children in remission. The plasma levels of IgE, IL-4, and IL-13 were significantly increased in children with active INS (P<0.05). miR-24 and miR-27 were at lower levels in children with active non-atopic INS (P<0.05). Transfection experiments indicated that upregulation of each miRNA decreased the percentage of Th2 cells and the level of IL-4 (P<0.05), and down-regulation of each miRNA had the opposite effects (P<0.05). Conclusion: Children with active INS, with or without atopy, had higher levels of IgE, possibly related to their higher levels of IL-13 and IL-4 due to drift toward Th2 cells. miR-24 and miR-27 suppress the expression of Th2 cells and have a critical function in Th2 expression in INS.

Purpose: We investigated the pathogenesis of idiopathic nephrotic syndrome (INS) by measuring the effects two specific miRNAs on Th2 cells in children with this disease.Methods: After informed consent, we enrolled 20 children with active INS before steroid initiation, 20 children with INS in remission after steroid therapy, and 20 age-matched healthy controls. Flow cytometry was used to measure the levels of Th2 cells and a cytometric bead array was used to measure the levels of IgE, interleukin (IL)−4, and IL-13. RT-PCR was used to measure the levels of miR-24 and miR-27 in CD4+TCD25− cells. PBMCs were isolated using Ficoll density gradient centrifugation, and transfected with different mimic or inhibitor miRNAs. RT-PCR was used to measure the expression of different RNAs, and flow cytometry was used to determine the percentage of Th2 cells.Results: Relative to healthy controls, children with active INS had higher percentages of Th2 cells (P &lt; 0.05), but there was no significant difference in controls and children in remission. The plasma levels of IgE, IL-4, and IL-13 were significantly increased in children with active INS (P &lt; 0.05). There were lower levels of miR-24 and miR-27 in children with active non-atopic INS (P &lt; 0.05). Transfection experiments indicated that upregulation of each miRNA decreased the percentage of Th2 cells and the level of IL-4 (P &lt; 0.05), and down-regulation of each miRNA had the opposite effects (P &lt; 0.05).Conclusion: Children with active INS, with or without atopy, had higher levels of IgE, possibly related to their higher levels of IL-13 and IL-4 due to a drift toward Th2 cells. miR-24 and miR-27 suppressed the expression of Th2 cells and have a critical function regulating Th2 cell expression in INS.

A gyermekkori nephrosis 90%-a idiopathiás nephrosis szindróma. Az idetartozó három kórkép, a minimal change betegség, a mesangialis proliferatio és a focalis sclerosis hasonló klinikai képpel jelentkező, eltérő prognózisú és terápiás válaszú betegség. Dolgozatunk célja az idiopathiás nephrosis szindrómába tartozó kórképek kialakulásával, progressziójával összefüggő genetikai ismeretek, génexpressziós változások áttekintése és funkcionális csoportosítása. A génexpressziós változások meghatározásának eszközeként, dolgozatunk röviden összefoglalja a northern blot, a ribonuclease protection assay, az in situ RNS-hibridizáció, a kvantitatív RT-PCR és a microarray módszerek lényegét. Az eddig elvégzett vizsgálatok a DNS-szintézis és repair gének, növekedési faktorok, extracelluláris mátrix, extracelluláris ligandreceptorok, extracelluláris jelátvitel zavarai mellett kiemelik a metabolikus és transzporter gének, illetve az immunszabályozó gének molekuláris eltéréseit, amelyek összefüggésben vannak az idiopathiás nephrosis szindróma eddig megismert molekuláris hátterével. A chiptechnológia fejlődésével és elterjedésével ezek a markerek és a hagyományos vizsgálati módszerek párhuzamos alkalmazása rutindiagnosztikai szempontból is fontossá válhat.

Abstract Introduction Most of the studies reporting the negative impact of idiopathic nephrotic syndrome on health-related quality of life in children and adolescents were conducted with generic quality-of-life instruments rather than disease-specific instruments. The consistency of these studies' findings using these generic instruments is not well established. Aim This systematic review aims to determine the reliability of current generic quality-of-life instruments in assessing health-related quality of life among children and adolescents with idiopathic nephrotic syndrome. Methods We searched the PubMed, MEDLINE, EMBASE, and Google Scholar databases for articles published between 2000 and 2020, using appropriate descriptors. We included primary studies that met the eligibility criteria, independently screened their titles and abstracts, and removed all duplicates during the study-selection process. We resolved disagreements until a consensus was reached on study selection. We independently retrieved relevant data, including the generic quality-of-life instruments and the subjects’ and controls’ aggregate health-related quality of life scores, using a preconceived data-extraction form. Results Ten original articles were selected for qualitative and quantitative analyses. Some of the studies reported the following significant findings. The mean health-related quality of life scores for children with prevalent and incident nephrotic syndrome were 68.6 (range, 52.6–84.6) and 73.7 (range, 55.9–91.5), respectively. Children with idiopathic nephrotic syndrome and their controls with other chronic diseases had median scores of 65 (interquartile range, 59–68.75) and 62.2 (interquartile range, 58.05–65.78). Patients on oral immunosuppressive drug and intravenous rituximab reportedly had median scores of 76.2 and 72.6 and mean scores of 71.4 (range, 55.4–87.4) and 61.6 (range, 42.1–81.1) respectively for quality-of-life assessment on the ‘school functioning domain.’ Conclusions The health-related quality of life scores in patients with idiopathic nephrotic syndrome are consistently low. Lower scores occur in prolonged disease duration and severe clinical phenotypes, whereas the scores are higher than the scores obtained in other chronic diseases. These consistent findings underscore the reliability of the current generic instruments in assessing health-related quality of life in patients with idiopathic nephrotic syndrome.

Disease Signature

Idiopathic nephrotic syndrome (INS) is the most frequent primary glomerular disease in children, displaying high grade proteinuria and oedema. The mainstay of therapy are steroids, and patients are usually classified according to the treatment response (sensitive vs. resistant). The mechanisms involved in INS pathogenesis and treatment responsiveness have not yet been identified. In this context, the analysis of urinary extracellular vesicles (UEv) is interesting, since they represent a molecular snapshot of the parental cells, offering a “fingerprint” for monitoring their status. Therefore, the aim of this study is to verify the feasibility of using UEv of INS patients as indicators of therapy response and its prediction. UEv were isolated from the urine of pediatric patients in remission after therapy; they showed characteristic electrophoresis profiles that matched specific patient subgroups. We then built a statistical model to interpret objectively each patient UEv protein profile: in particular, steroid-resistant patients cluster together with a very distinct pattern from other INS patients and controls. In conclusion, the evaluation of the UEv protein profile looks promising in the investigation of INS, showing a disease signature that might predict clinical evolution.
