To highlight the importance of laboratory findings and early molecular testing in diagnosing tick-borne anaplasmosis, particularly in a patient with acute myocarditis.
Approach:
Case Presentation: A 79-year-old man presented with fatigue, chills, weakness, and a fall, leading to initial laboratory testing.
Clinical Progression: The patient developed hypoxia and acute myocarditis, confirmed by elevated troponin and imaging studies.
Treatment and Outcome: Doxycycline treatment led to rapid improvement in clinical condition and normalization of cardiac function at follow-up.
Key Findings:
Anaplasma phagocytophilum infection should be considered in patients with unexplained febrile illness and laboratory abnormalities.
Characteristic laboratory findings include thrombocytopenia, lymphopenia, elevated liver enzymes, and acute kidney injury.
Peripheral blood smear can provide a rapid presumptive diagnosis when neutrophil morulae are identified.
Interpretation:
Limitations:
The case report is based on a single patient, limiting generalizability.
The report does not address the long-term outcomes of anaplasmosis in other populations.
Conclusion:
Anaplasmosis should remain in the differential diagnosis for unexplained febrile illness in endemic areas, with early laboratory recognition and treatment being vital.
