Severe thrombocytopenia in a patient with hepatitis C treated with eltrombopag from off-label drug use to on-label drug use: a case report.
Article in Journal of medical case reports, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionOff-label drug use refers to drug use beyond the specifications authorized for marketing. Eltrombopag is a new thrombopoietin receptor agonist which was used successfully in this critical case of thrombocytopenia associated with hepatitis C infection before it became an approved drug for such cases. CASE PRESENTATION: A 56-year-old Kuwaiti woman with hepatitis C virus infection was treated with pegylated interferon α-2a and ribavirin, laboratory test results prior to therapy were within normal values. After 4 weeks of that treatment, she developed neutropenia and severe thrombocytopenia. Her hepatitis C virus treatment was stopped for many years until eltrombopag was used as an off-label drug with an episode of severe thrombocytopenia. Her platelets count returned to normal level when triple therapy for hepatitis C virus was used successfully.
conclusionsAn off-label drug should be used only when it is the best available drug, based on evidence from on-going multicenter trials. It could be life saving for some patients in critical situations. However, clinical use of eltrombopag later confirmed that it is a safe and effective drug for immune thrombocytopenic purpura or thrombocytopenia associated with hepatitis C virus infection.
