Though known to be endemic to Latin America, prevalence in the United States is also increasing with improved recognition of locally acquired cases, especially in Texas. Autochthonous cases occur throughout the Southern United States, but the geographic range is anticipated to shift northwards as a result of climate change. Chagas disease is referred to as a \"silent and silenced disease\" by the World Health Organization as most people show no signs or symptoms for years following acute infection, and it primarily affects individuals who are socioeconomically disadvantaged. Historically, Chagas disease has been underrecognized. In the absence of treatment, infected individuals progress to a clinically silent or \"indeterminate form\" of infection that persists for life. While most patients with indeterminate Chagas disease do not have long-term sequelae, ∼30%-40% will develop end-organ cardiac or gastrointestinal disease decades after infection. Due to its protean clinical presentations, diagnosis requires a high clinical index of suspicion and knowledge of the epidemiology. Traditionally, the diagnosis is based on serology, visualization of the parasite in blood, and polymerase chain reaction (PCR), all of which require suspecting the infection.

We used frontier large language models (LLMs) on patient and caregiver narratives at scale to describe how burden shifts with disease course.</p><p><strong>Methods: </strong>We analyzed 189 testimonials from the Peggy Lillis Foundation corpus, sorted into 4 cohorts with recurrence (<i>r</i>) and fulminant (<i>f</i>) severity as axes (rfCDI, fCDI, rCDI, non-rfCDI). Two independent LLMs coded 8 thematic domains, 4 fulminant flags, 13 emerging semantic fields, the dominant dimension, and narrative arcs. Two physicians independently coded a subset for inter-rater reliability (PABAK, Gwet's AC1).</p><p><strong>Results: </strong>Treatment trajectory was the dominant theme in recurrent disease, whereas death and near-death dominated nonrecurrent fulminant narratives. Psychological burden was near-universal in fulminant disease (98.0% in rfCDI, 97.2% in fCDI). Caregiver and bereavement content concentrated in fCDI (66.7%). Diagnostic failure was frequent across recurrent cohorts (47.6-56.1%). Mentions of bacteriotherapy (fecal microbiota transplantation) concentrated in recurrent cohorts (60.2% rfCDI versus 5.6% fCDI). Financial, mental-health, and caregiver burdens were prominent and remain largely unaddressed by guidelines. Human-human reliability was substantial (PABAK 0.79 for semantic fields, 0.76 for domains); arc coding was least reliable.</p><p><strong>Conclusions: </strong>Patient narratives reveal a course-dependent, multidimensional burden in CDI. Concrete gaps exist between what patients prioritize, what guidelines recommend, and what therapy access provides. Frontier-LLM coding, validated against clinicians, offers a reproducible route to translate these priorities into research, care, and policy.</p>","PeriodicalId":19517,"journal":{"name":"Open Forum Infectious Diseases","volume":"13 10","pages":"ofag650"},"PeriodicalIF":3.8,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13660696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149182733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
