Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Benzylpenicillin - single dose
Treatment: Drugs - Benzylpenicillin - three days
Treatment: Drugs - Gentamicin - single dose
Treatment: Drugs - Gentamicin - three days
Treatment: Drugs - Cefalexin - post single dose of IV antibiotics for the remaining two days

Experimental: Arm 1, 1 dose - * Single dose IV to cover Gram negative bacteria followed by 2 days of oral antibiotics
* Single dose IV to cover Enterococcus spp

IV antibiotics are as per local institutional guidelines and microbiology eg: IV gentamicin with or without IV benzylpenicillin. Gentamicin is used when Gram Negative coverage is appropriate, benzylpenicillin is also used when Enterococcus coverage is appropriate, depending on local microbiology data. Once the IV component is complete the patient will be given an oral antibiotic (cefalexin) on day 2 and 3 of the study.

Active comparator: Arm 2, 3 doses - * 3 doses IV to cover Gram negative bacteria
* 3 days IV antibiotics to cover Enterococcus spp

IV antibiotics are as per local institutional guidelines and microbiology eg: IV gentamicin with or without IV benzylpenicillin. Gentamicin is used when Gram Negative coverage is appropriate, benzylpenicillin is also used when Enterococcus coverage is appropriate, depending on local microbiology data.


Treatment: Drugs: Benzylpenicillin - single dose
Participants will receive a single dose of IV antibiotic (benzylpenicillin).

Benzylpenicillin dosing: 1 month - 18 years, IV or Intramuscular (IM) 30 mg/kg (maximum 1.2 g) every 6 hours.

Treatment: Drugs: Benzylpenicillin - three days
Participants will receive three days of this IV antibiotic (benzylpenicillin).

Benzylpenicillin dosing: 1 month - 18 years, IV or Intramuscular (IM) 30 mg/kg (maximum 1.2 g) every 6 hours. For severe infections, use up to 60 mg/kg (maximum 2.4 g) every 4-6 hours.

Treatment: Drugs: Gentamicin - single dose
Participants will receive a single dose of IV antibiotic (gentamicin).

Gentamicin dosing: Children =10 years old: 7.5 mg/kg (maximum dose 320 mg) Children \>10 years old: 6-7 mg/kg (maximum dose 560 mg)

Treatment: Drugs: Gentamicin - three days
Participants will receive three days of this IV antibiotic (gentamicin).

Gentamicin dosing: Children =10 years old: 7.5 mg/kg (maximum dose 320 mg) Children \>10 years old: 6-7 mg/kg (maximum dose 560 mg)

Treatment: Drugs: Cefalexin - post single dose of IV antibiotics for the remaining two days
Oral antibiotic will be as per local guidelines. i.e. Cefalexin 25mg/kg (maximum dosage 500mg) 4 times a day or 33mg/kg (maximum dosage 500mg) 3 times a day
