Association between serum tumor necrosis factor-alpha level and the efficacy of infliximab for refractory pouchitis after restorative proctocolectomy in patients with ulcerative colitis.

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
objectivesAlthough the aetiology of pouchitis after restorative proctocolectomy in ulcerative colitis (UC) remains unknown, infliximab (IFX) is often effective for this condition. However, indicators and predictors of treatment efficacy remain unclear. In this study, the association between serum tumor necrosis factor-alpha (TNF-α) levels and refractory pouchitis was evaluated.
methodsWe conducted a prospective study between January 2014 and April 2016. Patients with antibiotic-refractory pouchitis were treated with IFX. Serum TNF-α levels were measured before IFX induction. Diagnoses were confirmed using the modified Pouchitis Disease Activity Index (m-PDAI). Responders were defined as patients with an m-PDAI score lower than 5. Recurrence was defined as an m-PDAI score exceeding 5 during maintenance treatment or a need for additional treatments. Associations between serum TNF-α level and efficacy of IFX during 52 weeks of maintenance therapy were evaluated.
resultsThirteen patients were eligible for this study. The short-term efficacy was 8/13 (61.5%). Four patients could not be maintained with IFX alone. The cumulative maintenance ratio was 30.8%/52 weeks, and the cut-off value for serum TNF-α was 1.93 pg/mL for short-term response. Although there was no significant association between serum TNF-α and treatment response, IFX treatment was unsuccessful for all five patients with TNF-α levels below 1.93 pg/mL, including four short-term non-responders and one long-term non-responder.
conclusionSerum TNF-α level was not an independent predictor of IFX efficacy for refractory pouchitis. However, IFX may be effective for patients with elevated serum TNF-α. Future studies should assess this possibility.
