Polyarteritis nodosa presenting with severe upper gastrointestinal bleeding: a case report.
Article in Journal of medical case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPolyarteritis nodosa is a relatively uncommon type of systemic necrotizing vasculitis that primarily affects medium-sized arteries. While gastrointestinal involvement is known in polyarteritis nodosa, heavy gastrointestinal bleeding due to gastric ulceration is relatively uncommon. We present the case of an 81-year-old male of Chinese ethnicity who experienced severe gastrointestinal bleeding as a result of polyarteritis nodosa and an innovative treatment approach for a better patient outcomes. CASE PRESENTATION: Upon admission to the medical intensive care unit, the patient underwent a comprehensive diagnostic assessment, including examinations for cardiovascular and dermatological abnormalities, laboratory tests, autoantibody and tumor marker assessments, and imaging studies (such as endoscopies, whole-body computed tomography, and positron emission tomography-computed tomography scans), and a skin biopsy. The patient had tachycardia, hypotension, and extensive skin abnormalities on the lower extremities along with anemia, low platelets, and abnormal renal function. Upper gastrointestinal endoscopy revealed gastric and duodenal ulcers. Additional examinations, including electronic colonoscopy, capsule endoscopy, and whole-body computed tomography, were negative. A positron emission tomography-computed tomography scan showed increased uptake in the arterial walls and skin, which supported the diagnosis of polyarteritis nodosa, later confirmed by a biopsy of the skin on the lower extremities. Methylprednisolone, octreotide, and omeprazole were administered, leading to improvement in gastrointestinal symptoms, ulcer healing, and skin recovery. The patient continued with prednisone for 1 month.
conclusionThis case serves to inform gastroenterologists about the need to consider polyarteritis nodosa in severe upper gastrointestinal bleeding and underscores the importance of prompt, medication-based treatment for successful patient outcome.
