Co-existence of Thrombotic Thrombocytopenic Purpura and Megaloblastic Anaemia: A Case-Based Review.

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
Introduction: Thrombotic thrombocytopenic purpura is a rare and fatal thrombotic microangiopathy characterised by a pentad of microangiopathic haemolytic anaemia, thrombocytopenia, renal abnormalities, neurological abnormalities, and fever. Due to ineffective erythropoiesis, vitamin-B12 deficiency may rarely present as haemolytic anaemia. Case report: We report a case of a 42-year-old vegetarian female presenting as vitamin B12 deficiency anaemia found to have concomitant TTP, responding to plasmapheresis, corticosteroids, and rituximab therapy. Discussion: In this case of vitamin B12 deficiency with co-existent TTP, we hypothesise vitamin B12 deficiency as a contributory or precipitating factor for TTP. We reviewed similar cases in the literature to support this hypothesis. Timely detection of TTP and the initiation of treatment is of utmost importance as TTP has a high mortality when left untreated. The possible relationship with Vitamin B12 deficiency needs further exploration.
