About this trial

Clostridioides difficile infection (CDI) poses an increasing threat to infant and young child health, with detection rates rising annually. This retrospective study aims to explore the epidemiological characteristics, clinical manifestations, and potential biomarkers of CDI in children aged 0-2 years by examining three cohorts: (1) infants diagnosed with CDI, (2) asymptomatic carriers of C. difficile, and (3) healthy controls. Fecal samples from each group will undergo metagenomic sequencing and metabolomic profiling, coupled with questionnaire-based surveys for risk factor assessment. The findings are anticipated to identify key high-risk factors, elucidate the pathogenic mechanisms underlying infant CDI, and support the development of early diagnostic tools and preventive strategies.

Eligibility criteria

Qualifiers

Age Range: Infants aged 0 to 2 years (inclusive) at the time of sample collection or medical record documentation.

Data Availability: Complete medical records or available stool samples within the study's retrospective time frame.

Consent/Authorization:Retrospective data (e.g., existing medical records or stored biosamples) may be included under a waiver of consent if approved by the institutional review board (IRB). However, any new information obtained directly from participants or their guardians (e.g., via questionnaires) requires explicit informed consent.

Disqualifiers

Incomplete Data: Infants whose medical records lack sufficient information to confirm their CDI status or those without adequate stool sample results.

Ambiguous Diagnosis: Patients presenting with other infectious diseases or conditions that could not rule out alternative diagnoses for diarrhea (e.g., confirmed concurrent viral or parasitic infections) without conclusive C. difficile testing.

Severe Comorbidities: Infants with life-threatening congenital conditions (e.g., severe immunodeficiency syndromes) if these conditions significantly alter the gut microbiota or confound CDI diagnosis.
