When evaluating the clinical efficacy of agents used against Giardia, it is difficult to compare studies.?

When evaluating the clinical efficacy of agents used against Giardia, it is difficult to compare studies. They vary as to entry methodology (whether randomization was done and if treatment was blinded or open), population studied (children, adults, symptomatic and/or asymptomatic patients), outcome measures (clin ical efficacy and /or stool negativity), and duration of follow-up. Nevertheless, conclusions may be drawn from the studies when viewed as a whole, and statements can be made about the relative efficacy of the agents.

How many people are hospitalized with giardiasis?

Despite the recognition of G. lambliaclinical illness for the last 40 years, the nearly 5,000 people hospitalized with giardiasis annually in the United States 149, and the millions infected worldwide, there have been few reviews of therapy for this infection and no definitive treatment protocols have been published 58, 113, 150, 165, 261. In addition, only a handful of agents have been used in therapy, and the agents which are available may have adverse effects or be contraindicated in certain clinical situations. Also, resistance may play a role in some infections. This paper will review the agents currently used for the treatment of giardiasis. The history, mechanism of action, in vitro and clinical studies, and adverse effects are detailed for each drug class. In addition, special clinical situations are discussed and recommendations for therapy are made.

The nitroimidazoles class of agents used to treat G. lambliainfection includes metronidazole, tinidazole, ornidazole, and secnidazole. This class was discovered in 1955 and was found to be highly effective against several protozoan infections 240. Metronidazole [1-(β-hydroxyethyl)-2-methyl-5-nitroimidazole; Flagyl] was determined to be therapeutic against Trichomonas vaginalisand Entamoeba histolyticafollowing its discovery in the late 1950s 67, and in 1962 Darbon et al. reported that it could be used to treat giardiasis 57. Since this discovery, metronidazole and other nitroimidazoles have been used by clinicians as the mainstay of therapy of giardiasis.
