Patient records
Name: James (pseudonym)
Age: 35
Nationality: British
Diagnosis: Adult-onset Still's disease (AOSD), characterized by a triad of high fever, rash, and arthritis, accompanied by severe ferritinemia.
Treatment Hospital: Department of Rheumatology and Immunology, Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine
For a pilot, any undiagnosed illness means the end of his career. James' nightmare began with what seemed like a common cold, but turned into a 120-day ordeal of unexplained high fever.
1. 120 days of "fever of unknown cause"
Four months ago, James began experiencing daily high fevers, peaking at 39-40°C, accompanied by brief orange-red rashes and severe joint pain. He was hospitalized in Vietnam's best hospital, undergoing a full suite of infection, tumor, and immune screenings, including multiple blood cultures, PET-CT scans, and bone marrow aspirations, all of which came back negative. The only abnormality was in his serum ferritin, which was more than 100 times the normal level. He barely managed to stay afloat with high doses of nonsteroidal anti-inflammatory drugs and antipyretics, resulting in a 15-kilogram weight loss. His attending physician eventually diagnosed him with "fever of unknown origin (FUO)" and recommended trying empirical hormone therapy, but could not provide a definitive diagnosis.
2.Our value: To illuminate the path for experts amidst the fog of "FUO" (Full-Times of Innovation).
James's airline medical officer contacted us with a stringent requirement: "We need a definitive diagnosis to assess whether he can return to flying. 'Unexplained fever' is not an acceptable answer."
Faced with this challenge, we are keenly aware that our role is not that of a "question answerer," but rather a "problem-solving path planner." Our job is to provide top experts with the most efficient "problem-solving tools."
Step 1: Transforming fragmented information into a high-value "Diagnostic Reasoning Summary." Our case manager conducted an in-depth, structured review of James's scattered and inconsistently formatted medical records, lab reports, and imaging reports from his months-long stay in Vietnam. We extracted three core characteristics of his symptoms—"daily high fever, transient rash, and severe joint pain"—and tabulated all key test results, highlighting the abnormal indicator of "serum ferritin levels exceeding 100 times the normal value." This "FUO Diagnostic Reasoning Summary" itself does not contain any diagnostic conclusions; its value lies in presenting the complete clinical picture of a complex FUO patient in the clearest and most logically consistent way, allowing experts to grasp key clues in the shortest possible time.
Step Two: Precisely Matching Subspecialty Experts Based on Clinical Clues. During the abstract preparation process, we identified the symptom combination of "high fever + rash + joint pain + extremely high ferritin levels," which has specific diagnostic significance in the field of rheumatology and immunology. Based on this, we determined that the patient urgently needed not a general infectious disease or general practitioner consultation, but a specialized evaluation by one of the top rheumatology and immunology experts in China. We precisely matched James with the rheumatology and immunology expert team at Ruijin Hospital affiliated with Shanghai Jiao Tong University School of Medicine. In the remote pre-communication, we submitted the prepared abstract to the experts and posed a question purely based on service procedures: "Given the patient's current condition, are there indications for diagnostic treatment so that the treatment process can be initiated as soon as possible after his arrival in China?"
Step 3: Comprehensive care and monitoring to provide high-quality diagnostic evidence for experts. After James arrived in China, we assisted him with his hospital admission. Under the guidance of the expert team at Ruijin Hospital, he began a short-term, low-dose diagnostic treatment with glucocorticoids. Our coordinator assisted in daily observation and recording of changes in his temperature, rash, and joint pain, and synchronized this data with the medical team. Within 48 hours of starting medication, James's temperature returned to normal, his rash subsided, and his joint pain significantly improved. This dramatic treatment response provided crucial clinical evidence for the experts at Ruijin Hospital to ultimately confirm the diagnosis of "adult-onset Still's disease (AOSD)."
3.Post-diagnosis services and follow-up: Safeguarding your career
Once the diagnosis was confirmed, James' long-term management goal was to control his condition with the lowest effective dose of medication, prevent relapse, and meet the stringent medical examination requirements of aviation medicine.
Individualized tapering plan: We assisted experts in developing a detailed hormone and immunosuppressant tapering plan for him and established an "AOSD Pilot Health Management File." Monthly, we collected his symptom diary, blood routine tests, ferritin levels, and liver and kidney function data via remote follow-up, and generated trend charts.
Occupational health assessment support: We assisted him in compiling his medical records and follow-up data from China into an "Aviation Medicine Assessment Report" that met the requirements of the Civil Aviation Authority of Vietnam (CAAV), providing crucial medical evidence for his eventual passing of the medical examination and return to the skies.
Long-term early warning: We taught him to recognize early signs of AOSD relapse (such as characteristic rash and sore throat) and established an "emergency contact channel" so that he could contact Chinese experts for remote guidance within 24 hours once signs of relapse appeared.
4. Therapeutic Effects and Insights
Six months later, James successfully passed the CAAV medical examination and returned to the cockpit. In his thank-you letter to us, he said, "What you helped me regain was not just a diagnosis, but my entire career. The words 'fever of unknown origin' almost ruined my life. Thank you for helping me turn it into a manageable 'adult Still'."
