Plasma exchange with albumin replacement for Alzheimer's disease treatment induced changes in serum and cerebrospinal fluid inflammatory mediator levels.

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
objectiveThere is extensive literature indicating that inflammatory pathways are affected in Alzheimer's disease (AD). We examined whether plasma exchange with albumin replacement (PE-Alb) can impact the inflammatory status of AD patients and alter the relationship between inflammatory mediators and cognitive measures.
methodsSerum and cerebrospinal fluid (CSF) samples from 142 AD patients participating in the AMBAR trial (14-month schedule of PE-Alb treatment vs. placebo [sham PE-Alb]) were analyzed for changes from baseline for 19 inflammatory mediators (6 inflammatory cytokines, 9 chemokines, and 4 vascular injury indicators) at representative time points across the AMBAR study (lasting effects) as well as in pre- versus post-PE-Alb procedure (acute effects). Association between mediator changes and clinical outcomes reported in the AMBAR study (cognitive, functional, behavioral function, and global change tests) was assessed.
resultsPE-Alb significantly reduced IFN-γ, eotaxin, MIP-1α and ICAM-1 levels in serum, and eotaxin-3 and MIP-1β levels in CSF, at various time points during treatment (p < 0.05; false discovery rate-corrected). Vascular injury indicators were the mediators mostly affected by post- versus pre-PE-Alb level reduction. Increased serum MIP-1α levels were associated with worsening in ADAS-Cog, CDR-sb, and ADCS-CGIC scores in the placebo group, but not in the PE-Alb-treated group.
interpretationPeripheral intervention could affect AD by reducing inflammatory mediators in both peripheral and central compartments. Changes in MIP-1α due to PE-Alb were associated with changes in clinical outcomes.
