[Comparative evaluation of clinical effectiveness of treatment of giardiasis].

Giardia is the most common causes of protozoan diarrhea that leads to significant morbidity and mortality worldwide. The purpose of this study was to determine the clinical efficiency of different scheme of therapy giardiasis with new original plant preparation "Sausalin" (Kazakhstan). We conducted open clinical trial with participation of 93 patients with giardiasis. According the method of treatment the patients were divided into three groups.  Group I - Sausalin at the dose 300 mg/day; group II - Metronidazole at 750 mg/ day; group III - combination of Sausalin 300 mg/day and Metronidazole 750 mg/ day. The treatment was conducted during 10 days. The protozoal clearance rate and clinical symptoms were assessed. There were no significant differences in the efficiency of treatments in group I and group II. The protozoal clearance rate was 68% in group I (Sausalin); in group II -  42,1% (metronidazole). In group III - 83,2% (combination therapy) (р=0.001; 95% CI 54,6-89,7). There was no negative effect on clinical and biochemical blood analysis. We detected statistically significant differences in the dynamics of clinical symptoms (defecation disorders, dyspepsia, abdominal pain, asthenia) of giardiasis in a group of patients receiving Sausalin.The scheme with new drug Sausalin can be used as alternative treatment of Giardiasis. Moreover, the use of the Sausalin is improved the clinical symptoms and safety of therapy.
