Scrub typhus association with autoimmune biomarkers and clinical implications.
Article in PLoS neglected tropical diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundScrub typhus, a disease caused by Orientia tsutsugamushi, triggers systemic vasculitis and is prevalent in Eastern and Southern Asia. This study aimed to uncover the relationship between scrub typhus and autoimmune responses, focusing on antinuclear antibodies (ANAs) and the implications of elevated ANA titers during infection.
methodData from a total of 139 patients diagnosed with scrub typhus and 30 healthy controls were retrospectively analyzed through serum samples to assess the levels of ANAs and related autoantibodies. The study further examined the temporal variation of these antibody titers in relation to post-symptom progression and evaluated their association with clinical and laboratory parameters.
resultsThe study results detail significant differences in autoimmune responses between scrub typhus patients and healthy controls. ANA titers above 1:80 were detected in 71.2% of patients; these titers were elevated in only 13.3% of the healthy controls. High-titer positivity (1:640 or higher) was observed exclusively in the scrub typhus group. The distribution of ANA titers revealed a progressive increase in mean ANA and double-stranded deoxyribonucleic acid Immunoglobulin M (anti-dsDNA IgM) titers as the duration after symptom onset increased, indicating an augmented immune response over time. This trend was observed along with a systematic elevation in median anti-dsDNA IgM titers, highlighting the dynamic nature of immune responses in scrub typhus infection.
conclusionOur findings conclude a substantial autoimmunological reaction in scrub typhus patients, suggesting potential mimicry of autoimmune conditions like Systemic Lupus Erythematosus. These results underline the complex interplay between infectious diseases and autoimmunity, emphasizing the necessity for further research into these mechanisms and their clinical implications.
