From the Guidelines
The treatment for a 13-year-old female with Plasmodium falciparum malaria, severe anemia (hemoglobin 7 gm), and thrombocytopenia (platelets 50 k) should be intravenous artesunate as the first-line treatment, given the severity of the condition and the need for prompt antimalarial therapy. According to the most recent guidelines 1, intravenous artesunate is recommended for all forms of severe malaria, and it has been shown to have a faster parasite clearance time and shorter ICU stay compared to quinine 1.
Treatment Approach
The recommended dosage of intravenous artesunate is not explicitly stated in the provided evidence, but typically, it is administered at 2.4 mg/kg per dose given at 0,12,24, and 48 hours. After the patient shows clinical improvement and can tolerate oral medication, a switch to a complete course of oral artemisinin-based combination therapy (ACT) such as artemether-lumefantrine should be considered.
Supportive Care
- For the severe anemia, blood transfusion should be considered, typically with packed red blood cells.
- The thrombocytopenia usually resolves with effective antimalarial treatment and rarely requires platelet transfusion unless there is active bleeding or platelets drop below 10,000/μL.
- Close monitoring of vital signs, neurological status, blood glucose, fluid balance, and daily complete blood counts is essential.
- Supportive care should include antipyretics for fever, maintenance of hydration, and correction of any electrolyte imbalances.
Monitoring
As indicated by 1, for complicated malaria, continuous monitoring of cardiocirculatory, pulmonary, kidney, and metabolic parameters is essential to recognize and correct complications associated with severe malaria. Monitoring of peripheral blood parasitaemia should be done every 12 hours after starting treatment until a decline to <1% is observed and then every 24 hours till a negative result is observed.
Given the severity of the condition and the potential for rapid progression to life-threatening complications, particularly in children, prompt and aggressive treatment is necessary to improve outcomes in terms of morbidity, mortality, and quality of life.
From the FDA Drug Label
Atovaquone and proguanil hydrochloride tablets are an antimalarial indicated for: prophylaxis of Plasmodium falciparum malaria, including in areas where chloroquine resistance has been reported. (1.1) treatment of acute, uncomplicated P. falciparum malaria. (1.2) Treatment (2.2): Adults: Four adult strength tablets as a single daily dose for 3 days. Pediatric Patients: Dosage based on body weight (see Table 2). The efficacy of atovaquone and proguanil hydrochloride tablets in the treatment of the erythrocytic phase of non-falciparum malaria was assessed in a small number of patients. Of the 23 patients in Thailand infected with P. vivax and treated with atovaquone/proguanil hydrochloride 1,000 mg/400 mg daily for 3 days, parasitemia cleared in 21 (91.
The treatment for a 13-year-old female with Plasmodium falciparum (PF) positive malaria, severe anemia (hemoglobin 7 gm), and thrombocytopenia (platelets 50 k) is atovaquone-proguanil. The dosage is based on body weight, and the patient should be treated for 3 days. However, it is essential to note that the patient's severe anemia and thrombocytopenia may require additional medical attention and supportive care.
- Key considerations:
- Severe anemia and thrombocytopenia may require blood transfusions or other supportive care.
- Atovaquone-proguanil is not recommended for patients with severe renal impairment.
- The patient's condition should be closely monitored, and alternative antimalarial therapy may be required if there are concerns about the patient's response to treatment. 2 2
From the Research
Treatment Overview
- The patient is a 13-year-old female with Plasmodium falciparum (PF) positive malaria, severe anemia (hemoglobin 7 gm), and thrombocytopenia (platelets 50 k).
- The treatment for severe falciparum malaria typically involves the use of antimalarial medications.
Antimalarial Medications
- Artesunate is a commonly used medication for the treatment of severe falciparum malaria, as it has been shown to be more effective than quinine in terms of parasite clearance and safety 3.
- Artesunate is available for use in cases of severe malaria, although it may not be licensed in all countries 4, 5.
- Other antimalarial medications, such as atovaquone-proguanil and artemether-lumefantrine, may also be effective for the treatment of non-severe Plasmodium falciparum infections 6, 7.
Treatment Considerations
- The patient's severe anemia and thrombocytopenia should be taken into consideration when selecting a treatment regimen.
- Blood transfusions may be necessary to manage the patient's anemia.
- The patient's age and weight should also be taken into consideration when selecting a treatment regimen, as some medications may have specific dosing recommendations for pediatric patients 6.
Recommended Treatment
- Based on the available evidence, artesunate may be a suitable treatment option for this patient, given its efficacy and safety profile for the treatment of severe falciparum malaria 3, 4, 5.
- However, the treatment regimen should be individualized based on the patient's specific needs and medical history.
