A case of pneumonia caused by infection with Tropheryma whipplei complicated by cryptococcus during treatment with a Janus kinase inhibitor: a case report.
Article in BMC pulmonary medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
This report describes the case of a 41-year-old male patient complaining of a hacking cough. The patient was treated with a Janus kinase (JAK) inhibitor for psoriasis. Blood tests revealed mild lymphopenia and high levels of serum cryptococcal antigen. Chest computed tomography revealed infection in the lower lobe of the left lung. Metagenomic next-generation sequencing of bronchoalveolar lavage fluid revealed Tropheryma whipplei. Tropheryma whipplei and Cryptococcus antimicrobial therapies were sequentially administered. During follow-up, the patient showed clinical and radiographic improvement. Tropheryma whipplei is an opportunistic Gram-positive rod-shaped bacterium belonging to the family Actinomycetes. Lung involvement is an unusual but classic manifestation of Whipple's disease. This is the first report of pneumonia caused by infection with Tropheryma whipplei complicated by Cryptococcus. To our knowledge, this is the first case report of Tropheryma whipplei infection following the use of JAK inhibitors. Clinicians should be aware of opportunistic infections that can occur during treatment with JAK inhibitors.
