Prolyl hydroxylase inhibitor desidustat improves stroke outcomes via enhancing efferocytosis in mice with chronic kidney disease.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Patients with chronic kidney disease (CKD) are at a significantly increased risk of stroke and experience worse stroke outcomes and higher mortality. CKD exacerbates stroke risk and severity through a complex interplay of systemic inflammation, oxidative stress, and impaired clearance of uremic toxins, leading to neuroinflammation and microglial activation. Current acute ischemic stroke treatments, while effective in the general population, do not adequately address CKD-specific mechanisms, limiting their efficacy in this high-risk population. Prolyl hydroxylase domain (PHD) inhibitors have shown promise in treating anemia associated with CKD and may offer cerebroprotective benefits. However, the effects of PHD2 inhibition on long-term sensorimotor outcomes and the underlying mechanisms in mice with CKD remain largely unknown. Here, we investigated the impact of CKD on stroke severity and assessed the therapeutic potential of desidustat, a PHD inhibitor, in improving stroke outcomes. Using an adenine-induced CKD mouse model, we demonstrated that CKD exacerbated stroke-induced long-term sensorimotor deficits, increased neuroinflammation, and impaired microglial efferocytosis via dysregulation of the ADAM17-MerTK axis. Desidustat treatment in mice with CKD significantly improved long-term sensorimotor functional outcomes and reduced post-stroke neuroinflammation while enhancing microglial efferocytosis by reducing ADAM17 and enhancing microglial MerTK expression. In vitro studies using human-induced microglia-like cells further confirmed the ability of desidustat to enhance efferocytosis of apoptotic neurons by reducing the cleavage of MerTK. These findings suggest that desidustat may serve as a novel therapeutic strategy for improving stroke outcomes in patients with CKD, a population at high risk for stroke and poor functional recovery.
