This post hoc analysis reports long-term follow-up results from AGILE after a median follow-up of 28.6 months. Overall, 148 patients were randomized to receive ivosidenib-azacitidine (N=73) or placebo-azacitidine (N=75). Median OS was significantly longer with ivosidenib (29.3 months; 95% CI 13.2, not reached) than with placebo (7.9 months; 95% CI 4.1, 11.3; hazard ratio 0.42 [0.27, 0.65]; p<.0001). Hematologic recovery was faster, more durable, and conversion to transfusion independence (53.8% vs 17.1%; p=.0004) was more common with ivosidenib than with placebo. Of 33 ivosidenib-treated patients evaluable for molecular measurable residual disease (MRD), 10 converted to MRD negativity. Although OS did not differ significantly between MRD-negative and MRD-positive responders at the 0.1% variant allele frequency (VAF) threshold, MRD-negative patients had numerically longer survival. MRD status appeared more predictive of long-term OS when an exploratory 1% VAF threshold was applied. MRD response was not associated with IDH1 variant, VAF, inferred clonality, or number of baseline comutations. The previously reported safety profile was maintained. These long-term efficacy and safety results confirm the benefit of ivosidenib-azacitidine in this challenging-to-treat population and support its use as a standard of care with the longest reported survival benefit for intensive chemotherapy-ineligible patients with IDH1-mutated AML.

In contrast, long-term stored PCs exhibited elevated transsulfuration and taurine metabolism, along with higher levels of CD62P and CD63.

Here, we found that platelets from patients with APS exhibited lower CD73 activity and cAMP content than healthy controls. Platelet activation, as measured by the surface expression of CD62P and activated αIIbβ3, was negatively correlated with CD73 activity and cAMP content.

We identified critical roles for FcγRIIa, phospholipase C, and the Akt signaling pathway in platelet activation by APS IgG. We also tested whether various agents that boost intracellular cAMP could blunt APS IgG-induced platelet activation. Agonism of the adenosine 2A receptor (A2AR) and inhibition of phosphodiesterase 3 (PDE3) were both highly effective in this regard.

Red blood cells (RBCs) occupy approximately half of the clot volume, but their possible active contribution to contraction is unknown. The work was aimed at elucidating the ability of RBCs to promote clot shrinkage. To distinguish the effects of platelets and RBCs, we formed thrombin-induced clots from reconstituted human samples containing platelet-free plasma and platelet-depleted RBCs, followed by tracking the clot size. The clots before and after RBC-induced shrinkage were analyzed using histology and scanning electron microscopy. Tension developed in the RBC-containing plasma clots was measured with rheometry, and theoretical modeling was used to elucidate the clot shrinkage mechanisms. Platelet-depleted clots formed in the presence of RBCs exhibited >20% volume shrinkage within one hour. This process was insensitive to blebbistatin, latrunculin A, and abciximab. At a higher RBC count, clot shrinkage increased, whereas in the absence of RBCs no plasma clot shrinkage was observed. At low platelet counts, RBCs stimulated clot contraction proportionately to the platelet level. Inside the shrunken clots, RBCs formed aggregates. The average tensile force per 1 RBC was ∼120 ± 100 pN. Clots from purified fibrinogen formed in the presence of RBCs did not change in size, but underwent shrinkage in the presence of osmotically active dextran. Blood clot shrinkage can be caused by RBCs alone, and this effect is because of the RBC aggregation driven mainly by osmotic depletion. The RBC-induced clot shrinkage may reinforce platelet-driven blood clot contraction and promote clot compaction when there are few and/or dysfunctional platelets.</p>","PeriodicalId":9228,"journal":{"name":"Blood advances","volume":" ","pages":"3418-3428"},"PeriodicalIF":7.4,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12274830/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143973561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to determine the pooled statistics of the association between SCT and CKD. Studies published up to May 2024 that were available on PubMed, Embase, Global Health Library, and Web of Science were screened. We included studies that reported odds ratios or hazard ratios (HRs) of CKD and/or end-stage renal disease (ESRD) and that compared adults with SCT to those without SCT. The risk of bias was evaluated using the Risk Of Bias In Nonrandomized Studies-of Exposures tool. The pooled SCT prevalence was calculated among patients with CKD/ESRD. A random-effects analysis was performed. Only studies with low or some concerns of bias were included, corresponding to 18 847 participants with SCT and 1 060 818 without SCT. Participants with SCT had higher odds of having an estimated glomerular filtration rate (eGFR) of ≤60 mL/min per 1.73 m2, proteinuria, and eGFR ≤60 mL/min per 1.73 m2 and/or proteinuria. The pooled prevalence of SCT among African American individuals with ESRD was 10%; however, the heterogeneity was very high (I2, 85.6%). There was a higher HR for ESRD in the studies that included both males and females than in the study that included only females, suggesting that males have a higher risk of ESRD. Controversial results were observed for the association of CKD with hypertension and diabetes. SCT increases the risk of developing CKD and ESRD.
