Glycogen content and expression of CD10 and α-SMA in the microenvironment of viable human hepatic hydatid cysts.
Article in Gut pathogens, 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
backgroundWhile hepatic cystic echinococcosis (CE) has been extensively studied in animal models, its impact on the human liver microenvironment remains unclear. Elucidating its pathogenic mechanisms in humans may reveal novel prognostic biomarkers and potential therapeutic targets. We aimed to investigate the impact of CE on the glycogen content of hepatocytes, CD10 expression in the bile canaliculi, and the profibrotic α-smooth muscle actin (α-SMA) in the adjacent portal areas.
methodsThe study involved 20 cases with hepatic hydatid cysts and 20 controls. Histopathological and viability assessments were done for the surgically obtained samples. Glycogen storage was evaluated using periodic acid-Schiff (PAS) special staining. Expressions of α-SMA and CD10 were investigated using immunohistochemistry.
resultsBiochemical tests and eosin staining confirmed high viability of the metacestodes, and histopathology showed distorted portal tracts. In hydatid cases, 85% (17/20) exhibited mild PAS staining of the hepatocytes, whereas control liver tissues were intensely in 65% (13/20) of the cases (p < 0.001). The laminated layer of the metacestode showed a strong positive PAS staining. In hydatid cases, α-SMA expression in the portal connective tissue exhibited a score of 2 in 45% (9/20) of cases, versus a score of 0 in 85% (17/20) of the control (P < 0.001). Increased α-SMA was also observed in the adventitial layer of the cyst. CD10 expression in pericystic liver tissue was absent in 25% (5/20) of hydatid cases, while mild to moderate canalicular expression was recorded in 65% (13/20) of cases. Nevertheless, marked expression was detected in 80% (16/20) of the controls (P < 0.001).
conclusionAs a preliminary report, hepatic hydatidosis may lead to glycogen depletion and α-SMA induction, suggesting potential therapeutic targets. CD10 may serve as a prognostic and post-treatment monitoring marker. Larger studies with multi-center design are recommended.
