Recurrent perianal abscess and fistula in a patient with Glucose-6-phosphate dehydrogenase (G6PD) deficiency: a case report.
Article in BMC gastroenterology, 2026. 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
backgroundGlucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common inherited enzymatic disorder, typically associated with hemolytic anemia. However, emerging evidence points to its involvement in a wider range of physiological processes, including the regulation of oxidative stress, immune defense, and epithelial repair which could lead to various manifestations. This is the first report of association between G6PD deficiency and perianal abscess and fistula. CASE PRESENTATION: A 16-year-old male with a five-year history of recurrent perianal abscess and fistula presented with renewed symptoms despite prior surgical management. His mother and brother had also reportedly been diagnosed with perianal abscess and fistula. Laboratory findings showed anemia and elevated inflammatory markers, while imaging revealed an intersphincteric fistula tract. Colonoscopy exhibited focal active ileitis without granulomas. Whole-exome sequencing identified a hemizygous pathogenic/likely pathogenic mutation in the G6PD gene (c.653 C > T), suggesting a genetic contribution to the chronic inflammatory process.
conclusionsThis case highlights a possible association between G6PD deficiency and recurrent perianal abscess and fistula. Impaired immune response and epithelial repair linked to G6PD dysfunction may contribute to chronic perianal disease. Further studies are warranted to clarify this potential relationship.
