    Abstract:
    Giardia lamblia, the aetiological agent of human giardiasis, is a frequently identified protozoan infection of the upper small intestine. It mainly affects children and has a wide range of clinical manifestations, from asymptomatic carriage to acute or chronic diarrhoea with dehydration, abdominal pain, nausea, vomiting, excessive flatulence and weight loss. Standard treatment for giardiasis is commonly with 5-nitroimidazole (5-NI) compounds, or nitazoxanide; however, some individuals experience treatment failure. For such patients, a combination of two or more drugs may be a viable approach. We report our experience with 11 paediatric patients with drug-refractory giardiasis, for whom therapy with a combination of secnidazole (SNZ) (30 mg/kg/day, divided into 2 doses, for 3 days) and albendazole (ABZ) (400 mg daily for 5 days) resulted in cure for 9 of the 11 (82%) patients. This combination of drugs was well tolerated; only mild, transient, and self-limited side effects were reported and these did not require discontinuation of treatment. These results support the use of SNZ plus ABZ as an alternative treatment for paediatric patients with giardiasis who have failed conventional treatments. Further research is needed to establish the safety of this combination and how it compares to other combination strategies.
