Date:
Patient:
主诉 (zhǔ訴) (Chief Complaint):
Document the patient’s main reason for presentation, which can vary depending on the stage of the disease:
Early Stage (Hemolymphatic):
Fever (often intermittent)
Headache
Fatigue
Malaise
Joint pain and swelling
Lymphadenopathy (swollen lymph nodes)
Late Stage (Meningoencephalitic):
Altered mental status (confusion, personality changes)
Seizures
Sleep disturbances
Tremor
Poor coordination
Speech difficulties
History of Present Illness:
Onset, duration, and severity of symptoms
Travel history to endemic areas of sub-Saharan Africa
Potential exposure to tsetse flies (bites, hunting, etc.)
Past medical history (relevant illnesses, surgeries)
Physical Examination:
Vital signs (temperature, heart rate, blood pressure, respiratory rate) – May be normal in the early stage, fever common in later stages.
General examination: Assess for signs of malnutrition, lymphadenopathy, and neurological abnormalities.
Neurological examination (later stage): May reveal confusion, tremors, speech difficulties, and abnormal reflexes.
Laboratory Findings:
Microscopy:
Early Stage: Examination of blood smears or lymph node aspirate for trypanosomes (parasites).
Late Stage: Examination of cerebrospinal fluid (CSF) for trypanosomes.
Serological tests: Antibody detection tests (ELISA, IFAT) to confirm exposure to trypanosomes.
Other tests (may be ordered): CBC (complete blood count), electrolytes, liver function tests
Imaging Studies (may be helpful in some cases):
CT scan or MRI of the brain: May be used to assess brain involvement in the late stage.
Assessment:
Diagnose African trypanosomiasis based on clinical presentation, travel history, and positive laboratory findings (microscopy or serological tests).
Differentiate between the early (hemolymphatic) and late (meningoencephalitic) stages based on symptoms and potential CSF findings.
Consider the specific trypanosome species involved (impacts treatment choices).
Plan:
Treatment depends on the stage of the disease and the trypanosome species.
Early Stage:
Medications effective against bloodstream trypanosomes (e.g., pentamidine, suramin).
Late Stage:
Treatment to eliminate parasites from the bloodstream followed by medications that can cross the blood-brain barrier to target parasites in the CNS (central nervous system) – often requiring hospitalization and specialist care. (e.g., melarsomine, nifurtimox, eflornithine).
Supportive care: Fluid resuscitation, electrolyte management, and nutritional support are crucial.
Monitoring: Repeat blood smears or CSF examination to assess treatment response.
Preventative measures: Education on avoiding tsetse fly bites (protective clothing, insect repellent) for future travel to endemic areas.
Consultations (may be needed depending on the case):
Infectious disease specialist (specialist in parasitic infections)
Neurologist (if neurological complications are present)
Progress Notes:
Document the response to treatment, including changes in symptoms, parasite clearance from blood or CSF, and any side effects of medications.
Monitor for potential long-term neurological complications.
Address any ongoing concerns or challenges faced by the patient.

Early diagnosis and prompt treatment with appropriate medication are crucial for a good prognosis in African trypanosomiasis. Consultation with an infectious disease specialist is essential for optimal management.
