1 · What the graph read from it

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.

2 · The registry

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

Antibody-mediated rejection (AMR) continues to have a deleterious impact on kidney allograft survival. Recent evidence supports use of tocilizumab for treatment of chronic active AMR, but it has not been assessed for treatment of acute active AMR.

methodsWe performed a single-center, observational study of kidney transplant recipients who received at least 1 dose of tocilizumab in addition to conventional therapies for acute active AMR between October 2016 and October 2018 with follow-up through August 2019.

resultsSeven patients were included. All 7 patients received tocilizumab 8 mg/kg (max dose, 800 mg) monthly. We noted a 50% or greater reduction in immunodominant donor-specific antibodies in 4 of 6 patients. Renal function improved or stabilized in all patients throughout the duration of therapy. One patient developed cytomegalovirus esophagitis and 1 had a potential hypersensitivity reaction. In the extended follow-up, 1 patient had mixed rejection and 2 patients had T-cell-mediated rejection, which occurred 6 to 24 mo after completion of therapy.

conclusionsTocilizumab may be considered as an addition to conventional therapies for treatment of acute active AMR. More studies are needed to determine which patients may benefit from therapy and to examine the appropriate duration of treatment.
