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

Complement-mediated thrombotic microangiopathy (CM-TMA) is a clinical disorder driven by the generation of excess complement. It is characterized by thrombocytopenia and microangiopathic hemolytic anemia (MAHA) with microvascular thrombosis resulting in systemic organ damage (TMA). One form of CM-TMA, atypical hemolytic uremic syndrome (aHUS), is characterized by pathologic complement activation due to the loss of the natural regulators of the complement system, which results in systemic endothelial and organ damage. Lupus erythematosus is a multisystem immune complex disorder associated with activation of complement, as well as renal failure termed lupus nephritis (LN). A subset of these patients also develop TMA, with progressive life-threatening thrombocytopenia, MAHA, and progressive renal failure similar to aHUS. This subset of patients is poorly responsive to corticosteroids, cyclophosphamide, immunomodulation, and plasma exchange. In this article, we report 11 cases of LN associated with TMA progressing through these therapies, 10 of which were successfully treated with complement inhibition. Complement-regulatory protein mutations, including complement factor H (CFH), factor I, factor B, membrane cofactor/(CD46) and thrombomodulin, and CFH-related 1-3, were identified in 6 of 10 patients tested. One patient had a loss of a renal allograft. Three patients had concurrent antiphospholipid syndrome. Two of the 3 patients had normal D-dimers at this presentation. We believe that this subset of lupus patients, with clinical and pathologic manifestations of aHUS, define a separate entity that we believe should be termed CM-TMA associated with LN.
