What is the best pharmacological treatment for a 4-year-old boy with a positive COVID-19 test, presenting with cough, nasal congestion, and sore throat?

From the Guidelines

For a 4-year-old boy with mild COVID-19 symptoms, the best pharmacological treatment is to take paracetamol if they have fever and other symptoms that antipyretics would help treat, as recommended by the NICE guidelines 1. The treatment should focus on managing symptoms, and paracetamol is preferred to non-steroidal anti-inflammatory drugs (NSAIDs) for patients with COVID-19, according to the BMJ study 1.

• The child should be advised to drink fluids regularly to avoid dehydration, with no more than 2 litres per day.
• Antipyretics should not be used with the sole aim of reducing body temperature, but rather to help treat other symptoms such as discomfort or fever.
• It is essential to continue paracetamol only while the symptoms of fever and the other symptoms are present, as stated in the NICE guidelines 1.
• The child's hydration status should be closely monitored, and they should be encouraged to stay well-hydrated with water, diluted juice, or pediatric electrolyte solutions.
• A cool-mist humidifier may help with congestion, and saline nasal drops followed by gentle suctioning with a bulb syringe can provide relief.
• If the child develops difficulty breathing, persistent high fever, lethargy, or decreased fluid intake, immediate medical attention is necessary.

From the FDA Drug Label

The recommended dosage for pediatric patients weighing 1.5 kg to less than 40 kg is presented in Table 1.

Table 1 Recommended Dosage in Pediatric Patients Including Term* Neonates and Infants Weighing 1.5 kg to Less than 40 kg

Pediatric Patient Population | Loading Dose Via Intravenous Infusion | Maintenance Dose Via Intravenous Infusion

Less than 28 days old and at least 1.5 kg | VEKLURY 2.5 mg/kg on Day 1 | VEKLURY 1.25 mg/kg once daily from Day 2

At least 28 days old and 1.5 kg to less than 3 kg | VEKLURY 5 mg/kg on Day 1 | VEKLURY 2.5 mg/kg once daily from Day 2

At least 28 days old and 3 kg to less than 40 kg | VEKLURY 5 mg/kg on Day 1 | VEKLURY 2.5 mg/kg once daily from Day 2

The best pharmacological treatment for a 4-year-old boy with a positive COVID-19 test, presenting with cough, nasal congestion, and sore throat, is remdesivir (VEKLURY).

• The patient's weight is not provided, so it's essential to determine the weight to choose the correct dosage from Table 1.
• Assuming the patient weighs between 3 kg and less than 40 kg (a reasonable assumption given the age), the recommended dosage would be VEKLURY 5 mg/kg on Day 1 followed by VEKLURY 2.5 mg/kg once daily from Day 2.
• The treatment course should be initiated as soon as possible after diagnosis of symptomatic COVID-19 has been made and within 7 days of symptom onset.
• The recommended total treatment duration for non-hospitalized patients diagnosed with mild-to-moderate COVID-19 who are at high risk for progression to severe COVID-19, including hospitalization or death, is 3 days 2.

From the Research

Pharmacological Treatment for COVID-19 in Pediatric Patients

The patient in question is a 4-year-old boy with a positive COVID-19 test, presenting with cough, nasal congestion, and sore throat. Considering the available evidence, the following pharmacological treatments have been studied for COVID-19:

• Remdesivir: A study published in 2020 3 mentions Remdesivir as a treatment option for the pulmonary phase of COVID-19. Another study from 2020 4 discusses the use of Remdesivir in hospitalized patients with COVID-19, showing improved survival and decreased lung injury. However, a 2021 review 5 suggests that Remdesivir may have little or no effect on all-cause mortality at up to day 28 in hospitalized adults with SARS-CoV-2 infection.
• Monoclonal Antibody and Antiviral Therapy: A 2023 study 6 reviews the use of monoclonal antibody and antiviral therapy for mild-to-moderate COVID-19 in pediatric patients, but the data is limited.
• Other Treatment Options: A 2021 review 7 discusses various pharmacological treatments for mild to moderate COVID-19, including Bamlanivimab, nitazoxanide, ivermectin, Interferon Beta-1, vitamin D, Favirapir, peginterferon, levamisole, fluvoxamine, inhaled budesonide, and colchicine. However, these treatments are not specifically studied in pediatric patients.

Treatment Considerations for Pediatric Patients

When considering treatment options for the 4-year-old boy, it is essential to note that the available evidence is primarily based on adult populations. The 2023 study 6 highlights the limited data on the use of antiviral and monoclonal antibody therapies in children. Therefore, treatment decisions should be made on a case-by-case basis, taking into account the individual patient's needs and the available evidence.

Key Findings

• Remdesivir may be considered as a treatment option for COVID-19, but its effectiveness in pediatric patients is unclear.
• Monoclonal antibody and antiviral therapy may be considered for mild-to-moderate COVID-19 in pediatric patients, but more research is needed to determine their safety and efficacy.
• Other treatment options, such as those mentioned in the 2021 review 7, may be considered, but their use in pediatric patients is not well-studied.
