Giardiasis treatment in Turkish children with a single dose of ornidazole

Area of Science:

• Pediatric Infectious Diseases
• Gastroenterology
• Pharmacology

Background:

• Giardiasis, caused by Giardia lamblia, is a common intestinal infection in children.
• Current treatment guidelines often involve multi-day regimens of metronidazole or other agents.
• Exploring alternative, potentially more convenient, treatment options is crucial for pediatric care.

Purpose of the Study:

• To compare the efficacy of single-dose ornidazole with multi-day treatments of ornidazole and metronidazole in children diagnosed with giardiasis.
• To evaluate the effectiveness of different single-dose ornidazole regimens (20, 25, and 30 mg/kg).
• To assess the comparative efficacy of ornidazole versus metronidazole in a pediatric population.

Main Methods:

• A randomized study involving 175 children aged 2-15 years with confirmed Giardia lamblia infection.
• Treatment groups included single-dose ornidazole (20, 25, 30 mg/kg), 5-day ornidazole (25 mg/kg/day), and 7-day metronidazole (20 mg/kg/day).
• Efficacy was assessed by stool examination and clinical symptom evaluation on days 7, 10, and 14 post-treatment.

Main Results:

• Ornidazole demonstrated high eradication rates: 94-97% for single doses and 100% for the 5-day regimen.
• The 5-day ornidazole regimen achieved 100% eradication, while metronidazole achieved 89% eradication.
• All ornidazole treatment regimens showed significantly higher efficacy compared to metronidazole (p < 0.05).
• No significant side-effects were observed, and all patients experienced symptom resolution.

Conclusions:

• Single-dose ornidazole is a highly effective and well-tolerated treatment for pediatric giardiasis.
• Ornidazole, particularly in a single-dose regimen, offers a superior alternative to metronidazole for treating children with Giardia lamblia.
• The findings support single-dose ornidazole as a convenient and effective option for giardiasis management in children.
