الوصف: Abstract Background Microscopic polyangiitis (MPA), a kind of antineutrophil cytoplasmic autoantibody associated vasculitis (AAV), predominantly affects small-sized vessels. MPA is a significant cause of the pulmonary-renal syndrome. Pauci-immune necrotizing and crescentic glomerulonephritis is the typical renal histological feature of AAV. Tubulointerstitial lesions may occur and mostly form with inflammatory cell infiltration in the interstitium. However, a few cases reported only tubulointerstitial involvement without glomerular lesions in patients with MPA. Case presentation We present an MPA case, a 70-year-old male patient diagnosed with acute kidney injury accompanying the dialysis requirement. Only acute tubulointerstitial nephritis was revealed in kidney biopsy without evidence of glomerular injury. Also, interstitial pulmonary fibrosis was determined on computerized tomography, and myeloperoxidase antineutrophil cytoplasmic autoantibody was positive. Consequently, we have considered the main diagnosis as MPA. We did not prefer a standard tubulointerstitial nephritis treatment regimen due to the presence of life-threatening systemic vasculitis. Treatment was established like crescentic glomerulonephritis. Induction therapy consisted of pulse steroid, cyclophosphamide, and plasmapheresis. Unfortunately, severe SARS-CoV-2 infection caused death during induction therapy in this case. Conclusions The lack of glomerular injury and solely interstitial inflammation is atypical regarding AAV involvement in the kidney. This diversity might be initially considered as only a simple histological elaboration. However, it is a significant entity for guiding the treatment of AAV.

الوصف: Abstract Background Autosomal dominant polycystic kidney disease (ADPKD) is a common hereditary disorder with unclear disease mechanism. Currently, overt hypertension and increased renal volume are the best predictors of renal function. In this study, we assessed the usefulness of selected circulating microRNAs (miRs) to predict disease progress in a cohort with ADPKD. Methods Eighty ADPKD patients (44.6 ± 12.7 years, 40% female, 65% hypertensive) and 50 healthy subjects (HS; 45.4 ± 12.7, 44% female) were enrolled in the study. Serum levels of 384 miRs were determined by Biomark Real Time PCR.

الوصف: Ethylene glycol (EG) may be consumed accidentally or intentionally, usually in the form of antifreeze products or as an ethanol substitute. EG is metabolized to toxic metabolites. These metabolites cause metabolic acidosis with increased anion gap, renal failure, oxaluria, damage to the central nervous system and cranial nerves, and cardiovascular instability. Early initiation of treatment can reduce the mortality and morbidity but different clinical presentations can cause delayed diagnosis and poor prognosis. Herein, we report a case with the atypical presentation of facial paralysis, hematuria, and kidney failure due to EG poisoning which progressed to end stage renal failure and permanent right peripheral facial nerve palsy.

الوصف: Objective(s): This study aimed to show the effects of thymoquinone, which is known for its antioxidant, anti-inflammatory, and renal protective effects in contrast-induced nephropathy. Materials and Methods: This is an experimental study in rats. 7 groups were included within the scope of our study: sham-vehicle (n=3), premedication-control (n=6), model (n=6), isolated thymoquinone (n=3+3), low-dose thymoquinone (n=6), and high-dose thymoquinone (n=7). In addition to 48 hr of water deprivation, we pre-medicated the rats with intra-peritoneal indomethacin and L-NAME administration. After premedication, 12.5 ml/kg dose of a high osmolar contrast agent-diatrizoat (Urografin ) was administrated. Thymoquinone was administrated in two different doses of 1 mg/kg and 1.75 mg/kg for four days intraperitoneally. Renal functions, histopathological differences, oxidative stress parameters, and inflammatory indicators of rats were evaluated at the end of the study. Results: Significant decreases were observed in levels of serum creatinine and serum BUN with low-dose thymoquinone (1 mg/kg) administration. In light microscopy, significantly less histopathological damage was observed in the low-dose thymoquinone group compared to the contrast agent group. While high-dose thymoquinone is accepted as ineffective biochemically, toxic evidence was identified histopathologically. There were no significant differences between M and TA groups for serum MDA and SOD levels, which were compared to evaluate oxidative stress (P:0.99, P:0.98; respectively). TNF-α, iNOS, and NF-кB gene expressions were not significantly different between all groups (P:0.748, P:0.531, P:0.910; respectively). Conclusion: This experimental study has demonstrated for the first time the protective effect of the TQ substance for CIN in 1 mg/kg dose, in the accompaniment of biochemical and histopathological data in rats.

الوصف: Background: Peritoneal dialysis is a frequently used renal replacement treatment option in patients with end-stage renalfailure, and it is emphasized several times that it should be started as the first treatment in the literature. However, for manydifferent reasons, sometimes the treatment is stopped and switched to hemodialysis. In this study, we aimed to examinethe reasons and factors affecting the transition to hemodialysis in our unit.Methods: Fifty-five patients who were – transferred to hemodialysis – regularly attending the Peritoneal Dialysis Unit ofErciyes University Nephrology Department were included in our study. Biochemical analysis, peritoneal equalization test(PET), dialysis adequacy (kt/V), and creatinine clearance of these patients were recorded regularly. Regular cardiac exami-nations and ambulatory blood pressure measurements were also performed. The reasons for the transition from perito-neal dialysis to hemodialysis were also noted in detail.Results: The mean age of the patients was 54.02 ± 11.41 years, and 27 (62.8%) of the patients were male. While the shortestperiod spent on peritoneal dialysis was 13 months, the longest was 191 months. The most common type of permeabilityin PET analysis of the patients was observed as high-average. The most common reason for the transition to hemodialysiswas inadequate dialysis. Using univariate and multiple regression models, factors that predict the duration of stay in peri-toneal dialysis were examined. We found that the urine volume, total kt/V, and the number of peritonitis could be effectivein predicting this period.Conclusion: Peritoneal dialysis is a renal replacement option that has advantages such as patient comfort, preservation ofthe kidney’s remaining work, and social life. The reasons for the transition should be examined in detail, and the necessaryinterventions to prolong the time in peritoneal dialysis should be evaluated.
