What this Trial Is About
Researchers are conducting a combined retrospective and prospective cohort study at Beijing Chest Hospital to identify risk factors linked to mortality in patients with intestinal tuberculosis. The study first analyzes data collected over 15 years (2011 to 2025) from patients diagnosed and followed at the hospital. Using statistical methods, the study aims to find factors like age, disease severity, other illnesses, and treatment adherence that may impact survival. The study includes two groups: a retrospective cohort of patients diagnosed between 2011 and 2025 whose historical medical records and follow-up data are reviewed, and a prospective cohort of newly diagnosed patients enrolled after 2026 who will be followed over time. Data collected include demographics, clinical symptoms, laboratory tests, treatment details, and mortality outcomes to verify and supplement the findings from the first phase. Participants will provide clinical information through medical records or ongoing follow-up visits, allowing researchers to monitor their health status and treatment responses. Outcome measures focus on all-cause mortality, tracked over 15 years for the retrospective group and for 3 years from enrollment for the prospective group. This research helps improve understanding of factors influencing survival and may guide better management strategies for intestinal tuberculosis patients.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Aged 18 years or older at the time of intestinal tuberculosis diagnosis
- Diagnosed with intestinal tuberculosis based on clinical, laboratory, imaging, or pathological evidence
- For the retrospective cohort: diagnosed between January 2011 and December 2025 with complete medical and follow-up records
- For the prospective cohort: newly diagnosed, able to cooperate with regular follow-up, and willing to sign informed consent if applicable
- No severe cognitive impairment or mental illness affecting data collection or follow-up
You will not qualify if you...
- Incomplete diagnosis of intestinal tuberculosis without clear clinical, laboratory, imaging, or pathological confirmation
- Concurrent severe extrapulmonary tuberculosis affecting mortality independently
- For the retrospective cohort: incomplete medical records or missing key follow-up data
- For the prospective cohort: refusal to sign informed consent, inability to cooperate with follow-up, or lost to follow-up
- Severe comorbidities causing rapid death (e.g., advanced cancer, severe heart failure, end-stage liver/kidney disease) interfering with mortality analysis
- Cognitive impairment, mental illness, or other conditions preventing effective clinical information or cooperation
