OBJECTIVE: To evaluate the efficacy of mepacrine (quinacrine) in patients with niclosamide resistant Taenia saginata infection. METHODS: Eighty six cases with niclosamide resistant Taenia saginata (unresponsive to 2-8 courses of niclosamide) were treated with quinacrine (1 g) administered orally or via a nasogastric tube, and followed at 2, 4, 8 and 12 weeks for recurrence of passage of proglottids and presence of Taenia eggs in the stool examinations. Pre and post-therapy egg counts were obtained and egg viability was tested by staining with methylene blue. RESULTS: Eighty-one (94.2%) patients responded promptly with passage of the worm within 4-72 hours. The egg counts showed a drastic fall in 79 cases and a fall in viability from a median of 100% to 0% was observed. Only one patient demonstrated a relapse at 4 weeks. Gastrointestinal side effects occurred in 9 cases but were controlled easily by symptomatic therapy. CONCLUSION: We conclude that quinacrine is a safe, inexpensive, effective and generally well tolerated drug for the treatment of niclosamide resistant Taenia saginata infestations.

Toxoplasmosis, a parasitic infection, varies in its prevalence in various countries. Some studies have suggested its role in the causation of abortions. We reviewed the records of Microbiology Department at Sher-i-Kashmir Institute of Medical Sciences, Srinagar (Kashmir) and found that out of 2371 women with recurrent abortions and 310 women with neonatal deaths tested for IgM antibody against toxoplasma, 1260 (53.14%) and 215 (69.35%) tested positive respectively. One hundred and twenty-two women with recurrent abortions and 55 women with neonatal deaths who had tested positive for IgM antibody were followed during subsequent pregnancy and were treated with spiramycin; 115 94.26%) in current abortion group and 35 (63.64%) in neonatal death group delivered normal babies. We discuss the role of seropositivity for toxoplasma in women during reproductive period.

Characterization of T. vaginalis strains isolated from symptomatic and asymptomatic subjects was done by isoenzyme analysis. The pathogenicity of these isolates was checked in mouse model and in vivo drug susceptibility was determined. The isolates from symptomatic and asymptomatic individuals could not be grouped on the basis of isoenzyme analysis alone. All the strains except one, were pathogenic for mice, and metronidazole (50 mg/kg body weight) was effective in protecting the mice from T. vaginalis infection.
