A case report of progressive multifocal leukoencephalopathy during steroid treatment for ANCA-associated renal vasculitis.
Article in CEN case reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
case reportan 80-year-old woman presented with rapidly progressive glomerulonephritis and was admitted to our hospital. Myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA) was positive. We diagnosed ANCA-associated renal vasculitis (ANCA-RV). Treatment was initiated with intravenous methylprednisolone pulse therapy, followed by prednisolone (PSL) at 30 mg/day. We gradually reduced the PSL dose to 7.5 mg/day over 6 months. At that time, the patient developed disturbances of consciousness which progressed subacutely. MRI revealed regions of patchy white matter with an increased signal on T2-weighted, fluid attenuated inversion recovery (FLAIR) sequences and diffusion-weighted sequences. JC virus DNA was detected in the cerebrospinal fluid (CSF) by polymerase chain reaction (PCR), leading to a diagnosis of progressive multifocal leukoencephalopathy (PML). PML is a rare infectious demyelinating disease of the central nervous system caused by JC virus infection, occurring in highly immunosuppressed individuals such as HIV-infected patients and patients using some biological agents, and having a very poor prognosis. In the present case, PML may have been associated with steroid use, although there are very few case reports of PML in patients taking only steroids. We report progressive multifocal leukoencephalopathy during steroid treatment of ANCA-RV. When patients show progressive disturbance of consciousness during treatment for ANCA-RV, we need to take PML into consideration for differential diagnosis.
