Data for patients with specifically ANCA-associated renal vasculitis requiring intensive care unit (ICU) supportive care are limited and have mainly focused on long-term renal and overall outcome. Particularly, data on critical illness during the initial course of disease are scarce and remain poorly determined. Therefore, the purpose of this retrospective study was to identify predictors of critical illness in a cohort of patients with ANCA-associated renal vasculitis. We retrospectively included a total number of 53 cases with confirmed ANCA-associated renal vasculitis between 2015 till 2020 in a single-center cohort study. We here identified an association between low hemoglobin levels and requirement of ICU supportive care in patients with ANCA-associated renal vasculitis. Furthermore, levels of hemoglobin below 9.8 g/dL at admission independently predicted prolonged requirement of ICU supportive care in critically ill patients with ANCA-associated renal vasculitis. These findings confirm that low levels of hemoglobin negatively affect short-term outcome and could further improve our current understanding for the role of anemia in ANCA-associated renal vasculitis."],["dc.description.sponsorship","Else-Kröner research program"],["dc.description.sponsorship","Research program, University Medical Center, University of Göttingen"],["dc.description.sponsorship"," Georg-August-Universität Göttingen 501100003385"],["dc.identifier.doi","10.1038/s41598-022-23313-7"],["dc.identifier.pii","23313"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/118027"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-621"],["dc.relation.eissn","2045-2322"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Low levels of hemoglobin associate with critical illness and predict disease course in patients with ANCA-associated renal vasculitis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Decline of excretory renal function was significantly delayed in the absence of TSP1. Although Col4a3;Tsp1 DK0 mice did progress toward end-stage renal failure, their kidneys exhibited distinct histopathological lesions, compared with creatinine level- matched Col4a3 K0 mice. Although kidneys of both Col4a3 K0 and Col4a3;Tsp1 DK0 mice exhibited a widened tubulointerstitium, predominant lesions in Col4a3 K0 kidneys were collagen deposition and fibroblast accumulation, whereas in Col4a3;Tsp1 DK0 kidney inflammation was predominant, with less collagen deposition. Altered disease progression correlated with impaired activation of transforming growth factor-beta 1 (TGF-beta 1) in vivo and in vitro in the absence of TSP1. In summary, our findings suggest that TSP1 contributes to progression of chronic kidney disease by catalyzing activation of latent TGF-beta 1, resulting in promotion of a fibroproliferative response over an inflammatory response.

Kidney involvement is a common and severe complication of ANCA AAV which is observed in a considerable subset of patients, mainly affecting glomeruli. However, tubulointerstitial lesions have also been described in ANCA glomerulonephritis (GN). Therefore, we aim to describe active and chronic tubulointerstitial lesions in ANCA GN subtypes by systematic scoring analogous to the Banff scoring system while also utilizing clinical and laboratory findings. Methods: A total of 49 kidney biopsies with ANCA GN were retrospectively included in a single-center cohort study between 2015–2020. Results: We report that MPO-ANCA GN is associated with more severe deterioration of kidney function independent of systemic markers of AAV disease activity, and is also associated with increased proteinuria in MPO-ANCA GN and a decreased fraction of normal glomeruli. Finally, MPO-ANCA GN showed distinct, active, and chronic tubulointerstitial lesions. Conclusion: New insights into the pathophysiology of both entities, as well as differences in the clinical presentation of MPO- versus PR3-ANCA GN, could potentially pave the way for more precise treatment regimens.

Because epigenetic modifications play a role in maintaining tissue fibrosis, we used a murine model of ischemia-reperfusion injury to determine whether aberrant promoter methylation of RASAL1 contributes causally to the switch between physiological regeneration and tubulointerstitial fibrogenesis, a hallmark of AKI-to-CKD progression. It is known that the antihypertensive drug hydralazine has demethylating activity, and that its optimum demethylating activity occurs at concentrations below blood pressure-lowering doses. Administration of low-dose hydralazine effectively induced expression of hydroxylase TET3, which catalyzed RASAL1 hydroxymethylation and subsequent RASAL1 promoter demethylation. Hydralazine-induced CpG promoter demethylation subsequently attenuated renal fibrosis and preserved excretory renal function independent of its blood pressure-lowering effects. In comparison, RASAL1 demethylation and inhibition of tubulointerstitial fibrosis was not detected upon administration of the angiotensin-converting enzyme inhibitor Ramipril in this model. Thus, RASAL1 promoter methylation and subsequent transcriptional RASAL1 suppression plays a causal role in AKI-to-CKD progression."],["dc.identifier.doi","10.1016/j.kint.2016.07.042"],["dc.identifier.pmid","27692563"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/64543"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/307"],["dc.language.iso","en"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | C01: Epigenetische Kontrolle der Herzfibrose"],["dc.relation","SFB 1002 | D03: ENPP3-vermittelter Phosphat-Metabolismus bei der Herzfibrose"],["dc.relation.eissn","1523-1755"],["dc.relation.issn","0085-2538"],["dc.relation.workinggroup","RG E.

However, application of RASS for placement of antegrade HDCs has not been investigated yet. Therefore, we here report our first experience of applying RASS for US-guided tip positioning of antegrade-tunneled HDCs. Methods: We performed a cross-sectional study to assess the feasibility of applying the RASS for US-guided tip positioning of antegrade-tunneled HDCs. We included a total number of 15 antegrade-tunneled HDC insertions in 13 patients requiring placement of a HDC for the temporary or permanent treatment of ESKD in a single-center, cross-sectional pilot study. Results: The overall success rate of applying the RASS for US-guided tip positioning of antegrade-tunneled HDCs was 15/15 (100%) confirmed by portable anterior-posterior chest radiography, with no major adverse events after HDC insertions. In addition, this insertion technique demonstrated optimal HDC flow without any observed malfunction. Conclusion: This study investigated the efficacy of the RASS for US-guided tip positioning of antegrade-tunneled HDCs in patients with ESKD. Application of the RASS for US-guided tip positioning is an accurate and safe procedure for proper placement of antegrade-tunneled HDCs."],["dc.identifier.doi","10.1177/11297298221088763"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/107369"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-561"],["dc.relation.eissn","1724-6032"],["dc.relation.issn","1129-7298"],["dc.relation.orgunit","Universitätsmedizin Göttingen"],["dc.relation.orgunit","Klinik für Nephrologie und Rheumatologie"],["dc.rights","CC BY-NC 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc/4.0/"],["dc.title","The rapid atrial swirl sign for ultrasound-guided tip positioning of antegrade-tunneled hemodialysis catheters: A cross-sectional pilot study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
