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"]]

Prompted by various studies across multiple organs demonstrating that preconditioning regimens to induce endogenous regenerative mechanisms protect various organs from later incurring acute injuries, we here aimed to gain insights into the molecular mechanisms underlying successful protection and to explore whether such pathways could be utilized to inhibit progression of chronic organ injury. We identified a protective mechanism controlled by the transcription factor ARNT that effectively inhibits progression of chronic kidney injury by transcriptional induction of ALK3, the principal mediator of antifibrotic and proregenerative bone morphogenetic protein-signaling (BMP-signaling) responses. We further report that ARNT expression itself is controlled by the FKBP12/YY1 transcriptional repressor complex and that disruption of such FKBP12/YY1 complexes by picomolar FK506 at subimmunosuppressive doses increases ARNT expression, subsequently leading to homodimeric ARNT-induced ALK3 transcription. Direct targeting of FKBP12/YY1 with in vivo morpholino approaches or small molecule inhibitors, including GPI-1046, was equally effective for inducing ARNT expression, with subsequent activation of ALK3-dependent canonical BMP-signaling responses and attenuated chronic organ failure in models of chronic kidney disease, and also cardiac and liver injuries. In summary, we report an organ-protective mechanism that can be pharmacologically modulated by immunophilin ligands FK506 and GPI-1046 or therapeutically targeted by in vivo morpholino approaches."],["dc.identifier.doi","10.1172/JCI89632"],["dc.identifier.pmid","29664738"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/77269"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/308"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["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","1558-8238"],["dc.relation.issn","0021-9738"],["dc.relation.workinggroup","RG E.

We here aimed to directly compare levels of C3 and C4 for outcome prediction in ANCA-associated renal vasculitis.\n \n \n Methods\n Serum levels of complement components C3 and C4 were directly compared in association with clinical and outcome data in a retrospective cohort of ANCA-associated renal vasculitis.\n \n \n Results\n \n As compared to poor outcome prediction by low levels of complement C3 (\n p\n  = 0.0093), low levels of complement C4 did not associate with early requirement of kidney replacement therapy (KRT) or death (\n p\n  = 0.2396). In the subgroup that experienced KRT or death, low C3 levels identified 11/14 (78.6%,\n p\n  = 0.0071) and C4 levels 9/14 (64.3%,\n p\n  = 0.1786) cases. Interestingly, 2/14 (14.3%) patients that experienced KRT or death had isolated C4 lowering, and combining low C3 and/or C4 levels identified 13/14 (92.3%,\n p\n  < 0.0001) cases in this subgroup. Non-superiority to predict poor outcome by low C3 and/or C4 as compared to C3 alone in the total cohort was attributed to 4/24 (16.7%) patients with isolated C4 lowering in the subgroup that did not experience KRT or death.\n \n \n \n Conclusion\n While low levels of complement C3 were superior in predicting poor outcome in ANCA-associated renal vasculitis, a minor fraction with poor outcome had isolated C4 lowering not captured by serum C3 measurements.
