What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests giving an antibiotic called azithromycin to children aged 1-11 months in areas where many children die. The goal is to see if this reduces deaths by preventing infections. Azithromycin has been shown to reduce child mortality in various trials, particularly in sub-Saharan Africa.

Will I have to stop taking my current medications?

The trial information does not specify whether participants need to stop taking their current medications.

Is azithromycin safe for children?

Azithromycin is generally safe for children, with most side effects being mild or moderate, such as stomach issues. In studies, about 8.7% of children experienced side effects, which is similar to other antibiotics. Serious side effects are rare, and it can be safely used to treat bacterial infections in children. ^{1 2 3 4 5}

How is the drug azithromycin unique for treating pediatric conditions?

Azithromycin is unique because it can be given as a single-dose treatment for children with acute otitis media (ear infection), which helps with compliance, especially in areas with low resistance to the drug. It has a long half-life, meaning it stays in the body longer, allowing for less frequent dosing compared to other antibiotics. ^{3 6 7 8 9}

What data supports the effectiveness of the drug Azithromycin for pediatric health?

Azithromycin has been shown to be effective in treating respiratory infections in children, with a high success rate in conditions like pneumonia and bronchitis. In studies, it was found to be 'markedly effective' in 92.9% of cases and had a clinical success rate of 88% for treating ear infections in children. ^{3 6 10 11 12}

Published Research Related to This Trial

Azithromycin is an effective antibiotic for treating respiratory infections in children, but it should be used cautiously due to concerns about antibiotic resistance, particularly with pneumococcal bacteria.

It is generally not recommended for certain conditions like acute pharyngitis, acute otitis media, or pneumococcal community-acquired pneumonia in children, especially in those at high risk for bacteremia.

Azithromycin use in paediatrics: A practical overview. Ovetchkine, P., Rieder, MJ.[2021]

In a study of 15 pediatric patients aged 1 to 10 years, azithromycin (AZM) demonstrated a high efficacy rate of 92.9% in treating various respiratory tract infections, including pneumonia and bronchitis.

The treatment was generally well-tolerated, with only one case of moderate diarrhea reported, indicating that AZM is a safe option for pediatric patients with respiratory infections.

Single-dose azithromycin (30 mg/kg) demonstrated a high clinical success rate of 88% in treating children with otitis media, based on data from four clinical trials involving 619 patients.

The treatment was found to be safe, with mostly mild and temporary side effects, and showed excellent compliance rates of 99-100%, making it a suitable alternative for pediatric patients, especially in areas with low macrolide resistance.

In a study involving 32 pediatric patients, azithromycin (AZM) demonstrated a high efficacy rate of 96.7% in treating various bacterial infections, with 18 patients rated as having 'excellent' outcomes.

While AZM was generally well-tolerated, with only mild side effects reported, it is important to note some patients experienced slight changes in laboratory test results, indicating the need for monitoring during treatment.

In a randomized controlled trial involving 56 children with cystic fibrosis, both low (5mg/kg/day) and high (15mg/kg/day) doses of azithromycin did not show significant differences in improving lung function (FEV1) or reducing pulmonary exacerbations over 12 months.

While children tolerated both doses well without significant side effects, the study found that stopping azithromycin led to an increase in pulmonary exacerbations, indicating that the benefits of the treatment may diminish shortly after discontinuation.

A meta-analysis of nine studies involving 3,597 pediatric patients found that azithromycin has a statistically significant lower risk of adverse events compared to other antibiotics, indicating its relative safety in treating infectious diseases in children.

While azithromycin is generally safe, caution is advised with higher dosages, suggesting that careful monitoring is necessary to avoid potential side effects.

A meta-analysis of 14 studies showed that azithromycin (AZM) has a significantly lower incidence of adverse reactions (24.20%) compared to control treatments (48.05%), indicating a better safety profile for pediatric respiratory disease treatment.

AZM demonstrated fewer adverse reactions across various administration methods, including sequential therapy, intravenous, and oral routes, making it a safer and more appealing option for treating children with respiratory conditions.

In a review of 45 studies involving 4,499 children aged 6 months to 16 years, azithromycin was found to be safe for treating acute bacterial infections, with only 8.7% of children experiencing mild to moderate adverse events, primarily gastrointestinal.

The incidence of adverse events was similar between azithromycin and comparator treatments, with only 1.3% of azithromycin-treated children discontinuing treatment due to side effects, indicating its comparable safety profile to other antibiotics.

Azithromycin significantly reduces the risk of bronchopulmonary dysplasia (BPD) in extremely premature neonates, with a relative risk of 0.83 based on a review of 11 studies involving 473 neonates.

While azithromycin is associated with various adverse events, including respiratory and gastrointestinal issues, there was no significant increase in liver enzyme levels compared to placebo, indicating a relatively safe profile for this medication in neonates.
