Ultra-short celiac disease in children: histological and autoimmune features.

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
Ultra-short celiac disease (USCD) represents a histopathological variant with selective involvement of the duodenal bulb. The mechanisms underlying the sparing of the second duodenal portion remain unclear. The histopathological progression of USCD under continued gluten exposure is not yet defined and represents a significant gap in current understanding. This retrospective study assessed histological changes in the duodenal bulb and second portion of the duodenum in pediatric patients who maintained gluten consumption until a definitive USCD diagnosis. Inclusion criteria required persistent dietary gluten intake, initial diagnosis confirmed by Marsh-Oberhuber classification, and elevated tissue transglutaminase (tTG) antibody levels. Fifteen out of 35 patients with USCD underwent repeat endoscopies. Villous atrophy was consistently confined to the first portion of the duodenum, with preservation of the second portion despite gluten exposure. Extensive celiac disease (ECD), characterized by involvement of the second portion of the duodenum, was associated with a significantly increased prevalence of short stature (p < 0.001) and iron deficiency anemia (p = 0.010), as well as substantially higher titers of tTG antibodies (p < 0.001). Both the USCD and ECD groups had similar rates of additional autoimmune diseases. Conclusion: In children, USCD presents with a distinct and localized duodenal response to gluten. Although USCD presents with a milder clinical and serological profile, the comparable autoimmune burden underscores the necessity for accurate diagnosis and timely treatment. What is Known: • Patients with USCD typically demonstrate milder clinical symptoms and lower serological markers compared to those with more extensive small-intestinal involvement. • The histopathological response to ongoing gluten exposure in USCD has not been characterized to date. What is New: • USCD remains histologically confined to the duodenal bulb, with no progression to the second portion of the duodenum observed over time, even with continued gluten intake. • Isolated duodenal bulb involvement may be sufficient to initiate systemic autoimmunity in celiac disease, despite mild clinical and serological features.
