Prevalence of Helicobacter pylori and intestinal parasitic coinfections among patients with gastrointestinal complaints in a Rwandan Teaching Hospital.
Article in BMC infectious diseases, 2025. 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
backgroundIntestinal parasitic infections and Helicobacter pylori (H. pylori) constitute a global health challenge especially in low-income countries. In Rwanda, documentation about their co-infection is scarce. The aim of the present study was to determine the prevalence of co-infection with intestinal parasites and H. pylori and their association with gastrointestinal symptoms among patients attending the University Teaching Hospital of Butare (CHUB) in Rwanda. METHODS AND MATERIAL: A cross-sectional study was carried out on a total number of 356 patients after signing the consent form. A questionnaire was used to collect socio-demographic data, while medical records were consulted for clinicopathological characteristics. An H. pylori stool antigen test was used to determine H. pylori infection while a wet mount microscopic examination was used to determine intestinal parasites infection.
resultsIntestinal parasitic infections were detected in 132 individuals (37.1%), while H. pylori stool antigen tests were positive in 130 cases (36.5%). Coinfection with both intestinal parasites and H. pylori was observed in 43 participants (12.1%). A statistically significant association was found between Entamoeba histolytica/dispar infection and H. pylori status (χ² = 5.287, p = 0.021). Furthermore, participants with co-infections were more likely to suffer epigastric [adjusted odds ratio (aOR) = 2.996, p = 0.004] and abdominal pain (aOR = 2.884, p = 0.006) than those without infection or those with single infection.
conclusionThis study reveals a significant burden of H. pylori and intestinal parasitic infections, with notable rates of coinfection and strong associations with common gastrointestinal symptoms. The observed link between Entamoeba histolytica/dispar and H. pylori highlights potential pathogen interactions that may influence clinical outcomes. Despite certain limitations, these findings underscore the need for integrated diagnostic approaches and context-specific interventions to improve gastrointestinal health in endemic settings.
