TRENDS IN THE CLINICALPRESENTATION OF CELIAC DISEASE IN BRAZILIAN ADULTS SEEN IN THE LAST 50 YEARS IN A PRIVATE OFFICE.
Article in Arquivos de gastroenterologia, 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
backgroundSince the mid-20th century, celiac disease (CD) has evolved from being regarded as a predominantly pediatric disorder to one increasingly recognized across all ages. In Brazil, CD was initially underdiagnosed, but diagnostic advances and greater awareness have led to a broader understanding of its epidemiology and clinical spectrum.
objectiveTo describe the evolving clinical, laboratory, and histological profile of Brazilian adults diagnosed with CD over the past five decades.
methodsA retrospective descriptive study was conducted including 181 adults with biopsy-confirmed CD managed at a referral private practice in in Curitiba, Brazil, from 1975 to 2025. Patients were stratified into three diagnostic phases: phase 1 (1975-2000), phase 2 (2001-2010), and phase 3 (2011-2025). Clinical manifestations, nutritional status, comorbidities, histological findings, and laboratory parameters were analyzed comparatively.
resultsThe cohort was predominantly female (84.8%), with a median age of 36 years at diagnosis. Marsh III lesions were observed in 98.0% of phase 1 cases, remaining the most frequent finding across phases. Underweight was prevalent in phase 1 (63.2%) but declined significantly in phase 2 (26.4%) and phase 3 (16.5%), reflecting, probably, earlier detection. Diarrhea predominated in phases 1 and 2, whereas constipation became more frequent in phase 3. Extraintestinal manifestations such as anemia, fatigue, and weight loss decreased over time, while reports of comorbid immune-mediated diseases and family history of gluten-related disorders increased.
conclusionOver the last 50 years, the clinical presentation of CD in Southern Brazil has shifted from advanced malnourished states with diarrhea to more heterogeneous profiles including constipation and overweight. Despite advances in serology, duodenal biopsy remains the gold standard for diagnosis. These findings underscore the importance of continuous clinical vigilance and reflect a sustained contribution to CD management in Brazil.
