From the Guidelines
The treatment plan for a patient with anaplasmosis presenting with confusion and severe fatigue should begin immediately with doxycycline 100 mg twice daily for 10 days, as recommended by the CDC 1. This antibiotic is highly effective against Anaplasma phagocytophilum, the causative bacterium. For patients who are severely ill, hospitalization may be necessary for intravenous doxycycline administration, monitoring, and supportive care including IV fluids for dehydration. Some key points to consider in the treatment plan include:
- Patients with allergies to tetracyclines might receive rifampin as an alternative, with a dose of 300 mg orally twice daily for adults or 10 mg/kg of body weight for children 1.
- Neurological symptoms like confusion require close monitoring, as they indicate more severe disease.
- Treatment should not be delayed while awaiting test results, as early intervention significantly reduces morbidity and mortality.
- Supportive measures should address symptoms such as fever and fatigue.
- Clinical improvement typically occurs within 24-48 hours after starting appropriate antibiotics, as noted in the CDC guidelines 1.
- The bacterium infects neutrophils and causes systemic inflammation, which explains the confusion and fatigue symptoms.
- Follow-up evaluation is important to ensure complete resolution of symptoms and to address any potential complications. It's also important to note that other classes of broad-spectrum antibacterial agents, such as beta-lactams, macrolides, aminoglycosides, and sulfonamides, are not effective against tickborne rickettsial diseases and may even be associated with increased severity of the disease 1. Therefore, doxycycline remains the preferred treatment option for anaplasmosis, and alternative treatments should only be considered in specific circumstances, such as allergies or pregnancy.

Treatment Plan for Anaplasmosis
The patient's diagnosis of anaplasmosis, presenting with confusion and severe fatigue, requires prompt treatment.
- The treatment plan typically involves the use of antibiotics, specifically doxycycline, as seen in the case reports 2, 3, 4, 5.
- Doxycycline is the recommended antibiotic for the treatment of anaplasmosis, with a typical course lasting 10-14 days 5.
- In some cases, patients may experience severe complications, such as secondary hemophagocytic lymphohistiocytosis (HLH), which may require additional treatment with steroids and anakinra (an IL-1 receptor antagonist) 2.
- It is essential to initiate treatment promptly, as early treatment improves mortality and reduces the risk of complications 2, 3.
- The patient's symptoms, including confusion, severe fatigue, vomiting, headache, and body aches, should be closely monitored, and the treatment plan adjusted as needed.
- Hydration and supportive care may also be necessary to manage the patient's symptoms and prevent further complications 3.
