AbstractAbstract
[en] Highlights: • Erp44 expression is induced in the glomeruli of type 2 diabetes mice. • Erp44 depletion aggravates the features of diabetic nephropathy in type 2 diabetes mice. • Erp44 depletion exacerbates ER stress in type 2 diabetes mice. • Attenuation of ER stress via diminishes Erp44-depletion aggravated features of diabetic nephropathy. Diabetic nephropathy (DN) is a major complication of diabetes, and the dysfunction of endoplasmic reticulum (ER) plays an important role in its pathogenesis. ERp44, an ER resident chaperone protein, has been implicated in the modulation of ER stress, however, its role and mechanism in DN are not determined. Here, we show that ERp44 expression is upregulated in the glomeruli of db/db mice, a rodent model of type 2 diabetes. When ERp44 is depleted by in vivo shRNA-mediated knockdown, the features associated with DN including albuminuria level and glomerular basement membrane (GBM) thickness are aggravated, therefore suggesting a detrimental role of ERp44 depletion in DN progression. We further show that ERp44 depletion exacerbates ER stress in DN in db/db mice, and that attenuating ER stress with the chemical chaperone TUDCA remarkably diminishes the aggravated DN features caused by ERp44 depletion. These results suggest that the exacerbated ER stress is a critical factor for the detrimental effect of ERp44 depletion on DN progression in db/db mice. Thus, our study links the role of ERp44 in DN with ER stress regulation and may offer a potential therapeutic strategy to interfere DN progression.

AbstractAbstract
[en] The purpose of this study was to assess the association of measured glomerular filtration rate (mGFR) using camera-based method with early transplant outcomes. Diethylenetriamine pentaacetate renograms of all voluntary kidney donors between January 2016 and December 2022 at Kasturba Hospital, Manipal, India, were retrieved for the study. Recipient's post transplant biochemical parameters were collected and compared against donors with scaled mGFR >80 ml/min/1.73 m2 (Group 1) and with mGFR between 60 and 80 ml/min/1.73 m2 (Group 2). Donor-recipient pair age, anthropometric parameters, and their differences were also assessed against the immediate transplant outcome. Post transplant immediate graft function was assessed by post transplant nadir serum creatinine, day to achieve nadir serum creatinine, the incidence of slow graft or delayed graft function, and serum creatinine at 1-month post transplantation. Recipients with serum creatinine of >2.5 mg/dl on post transplant day 7 were taken as slow graft function. A total of 161 donor-recipient pairs were analyzed in the study. In recipients who showed persistently high serum creatinine post transplant, older donor age(p < 0.001), higher difference in body mass index among the donor-recipient pair (p= 0.03), and mGFR <80ml/min (p < 0.001) were significantly associated. Slow graft function was significantly more in Group II recipients, with donors having mGFR <80ml/min as compared to Group I with mGFR >80 ml/ min (37.3% vs. 10.6%) (P < 0.001). Camera-based mGFR using Gate's formula is a reliable tool to predict inferior graft outcomes in the immediate post transplant period. Kidneys from donors with mGFR of 60-80 mL/min/1.73 m2 are likely to experience slow graft function in the immediate post transplant period. (author)

AbstractAbstract
[en] Highlights: • IL-7R is upregulated in the glomeruli of mice with adriamycin nephropathy. • IL-7R is upregulated in adriamycin-treated podocytes in vitro. • IL-7R activation through IL-7 stimulation induces podocyte injury and impairs filtration barrier function. The glomerular podocytes control filtration barrier permeability in the kidney, and their disturbance underlies the pathogenesis of idiopathic nephrotic syndrome (INS), a kidney disease that predominantly occurs in children. In this study, we found that the interleukin-7 receptor (IL-7R) was induced in the glomeruli of adriamycin (ADR)-induced mouse nephropathy, a rodent model of nephrotic syndrome. In addition, IL-7R was also induced by ADR in mouse podocytes cultured in vitro. Functionally, we discovered that IL-7R activation through the stimulation of recombinant IL-7 induced apoptosis of podocytes, and moreover, IL-7 stimulation inhibited nephrin activation and caused actin cytoskeleton disorganization, indicating that IL-7 stimulation induces podocyte injury. Furthermore, IL-7 stimulation impaired the filtration barrier function of podocyte monolayer. Together, these results identify IL-7 and its receptor IL-7R as potential regulators of podocyte function, which might offer a novel therapeutic target in the treatment of INS.

Purpose
Cortical biopsy is the cornerstone to reveal a cause of unexplained dysfunction of the kidney transplant. Nevertheless, only a few studies have reported the biopsy technique with its performance. We described a novel technique of ultrasound (US)-guided kidney transplant biopsy using cortex-only view and analyzed its diagnostic efficacy and safety.Materials and methods
Between January 2014 and December 2016, a consecutive series of 188 patients who underwent US-guided kidney transplant biopsy using cortex-only view by an experienced radiologist were evaluated (mean age, 46.1 ± 12.5 years; range, 21–79 years). Biopsy time, biopsy distance, biopsy core number, and glomerular number per patient were recorded. Successful biopsy (e.g., adequate, 10 or more glomeruli; marginal, 7–9 glomeruli) and complication rates were investigated, using Banff criteria and Clavien-Dindo classification, respectively.Results
Mean biopsy time, distance, and core number were 20.6 ± 6.7 min (range, 10–44 min), 3.2 ± 0.7 cm (range, 2.1–5.4 cm), and 1.9 ± 0.3 (range, 1.0–3.0), respectively. Mean glomerular number per patient was 20.4 ± 10.0 (range, 0–54). Adequate and marginal biopsy rates were 87.2% (164/188) and 95.2% (179/188), respectively. There was no major complication requiring treatment (no patient with Clavien-Dindo grade 2 or greater complication), while there were self-limiting minor complications in 5 patients (overall complication rate, 2.7%).Conclusion
US-guided biopsy using cortex-only view is feasible and safe in sampling cortical tissues of kidney transplant.Key Points
• Ultrasound (US)-guided kidney transplant biopsy using cortex-only view is feasible and safe.• Adequate and marginal biopsy rates were 87.2% and 95.2%, respectively.• No major complication requiring treatment occurred after biopsy.Primary Subject

AbstractAbstract
[en] Glomerular filtration rate (GFR) is a useful parameter for assessing overall kidney function. Many methods are used to measure GFR namely: the double plasma sample method (DPSM), the Gates method and the Equation-based method. Among them, DPSM is the gold standard in clinical research, but it is time-consuming and requires timed blood sampling. On the other hand, Equation-based method and the Gates method using the camera based technique are both simple and reliable. So, in this present study, we compared the Gates method with the Equation-based method such as Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) in patients with obstructive uropathy. A total of 248 patients referred to our Nuclear Medicine Department for the Diethylenetriamine Penta-Acetic acid (DTPA) dynamic renal scan during the study period of February 2021 to September 2022. 100/248 patients with obstructive uropathy were included in this present study. After adequate hydration, in-house Serum Creatinine evaluation was done to estimate GFR (eGFR) using the CKD-EPI equation as recommended by National Kidney Foundation (NKF) guidelines of 2014. Subsequently on the same day, the patient underwent a renal scan and GFR was calculated by applying Gates method (mGFR). The patients were divided into three groups based on their eGFR (ml/min/1.73m2) values, according to NKF guidelines: Group A: > 90, Group B: 60-89, and Group C: 60. Pearson correlation coefficient was calculated to find any correlation between mGFR and eGFR as per age distribution and eGFR range group according to NKF guidelines. Out of 100 patients (age range: 18-83 years; mean age: 42.32 years), 50% were males (age range: 18-80 years; mean age: 36.96 years) and 50% were females (age range: 20-83 years; mean age: 47.68 years). The mean serum creatinine was 0.89 mg/dl for the overall population; 0.93 for males and 0.83 for females. The mean mGFR in ml/min/1.732m2 for the entire population was 78.81, for males were 80.83, and for females were 76.60. On the other hand, the mean eGFR in ml/min/1.732m2 for the entire population was 98.95, and for males and females were 104.488 and 93.48. The Pearson correlation coefficient (R) for 18–40 years was 0.5016, 0.26 for 41–60 years, and 0.3311 for 61–90 years. Similarly, the R value was 0.3985 for Group A, 0.4774 for B, and 0.0303 for C. From the results, it is evident that there is a positive but weak correlation between mGFR and eGFR values. To conclude, CKD-EPI gives information about global renal function only, where as Gates method apart from giving global renal function also provides information about split renal function and drainage pattern. Moreover, it does not require timed blood sample collection. Thus, camera based method using Gates protocol should be the preferred choice for GFR measurement in clinical practice. (author)

AbstractAbstract
[en] Highlights: • A method for in vivo nephron progenitor cell replacement was developed. • Cell replacement via diphtheria toxin receptor was achieved in fetal mice. • Intra-amniotic diphtheria toxin injection reduces glomeruli and eliminates NPCs. • Intra-peritoneal is insufficient for NPC elimination in fetal mouse kidneys. To address the lack of organs for transplantation, we previously developed a method for organ regeneration in which nephron progenitor cell (NPC) replacement is performed via the diphtheria toxin receptor (DTR) system. In transgenic mice with NPC-specific expression of DTR, NPCs were eliminated by DT and replaced with NPCs lacking the DTR with the ability to differentiate into nephrons. However, this method has only been verified in vitro. For applications to natural models, such as animal fetuses, it is necessary to determine the optimal administration route and dose of DT. In this study, two DT administration routes (intra-peritoneal and intra-amniotic injection) were evaluated in fetal mice. The fetus was delivered by caesarean section at E18.5, and the fetal mouse kidney and RNA expression were evaluated. Additionally, the effect of the DT dose (25, 5, 0.5, and 0.05 ng/fetus-body) was studied. Intra-amniotic injection of DT led to a reduction in kidney volume, loss of glomeruli, and decreased differentiation marker expression. The intra-peritoneal route was not sufficient for NPC elimination. By establishing that intra-amniotic injection is the optimal administration route for DT, these results will facilitate studies of kidney regeneration in vivo. In addition, this method might be useful for analysis of kidney development at various time points by deleting NPCs during development.
