Ultrastructural studies, including stereological analyses of micrographs, have been made of five-worm primary infections of Hymenolepis diminuta from C57 mice to determine whether the immune destrobilation/rejection process was accompanied by significant changes in the fine structure of the scolex tegument. Destrobilation/rejection of worms occurred from Days 9-12 after infection. For the first 5 days after infection, the scolex tegument showed no detectable differences in ultrastructure compared with that of "control" worms from either Wistar rats or immunosuppressed C57 mice. By Day 6, large lipid deposits were observed in the tegument and associated musculature of worms from untreated C57 mice. Further, worms recovered from Days 6-8 after infection also showed increased activity of the Golgi apparatus, GER, and mitochondria of the tegument, resulting in increased numbers of discoidal secretory bodies. Concomitant with destrobilation/rejection from Day 9 was a drop in the number of secretory bodies, an increase in autophagic activity throughout the tegument, and a blistering of the tegument surface plasma membrane. The possible functional significance of the results is discussed in relation to host immunity.

Albendazole (ADZ) and praziquantel (PZQT) have been used as anthelmintics for over 30 years. Worldwide, hundreds of millions tablets are administered to people and livestock every year. ADZ is poorly orally absorbed (<5%), and its uptake is enhanced by high-fat meals, while PZQT is well absorbed (>75%) and uptake is enhanced by carbohydrate-rich meals. Both ADZ and PZQT are safe, but not recommended for children <2 years or for women in the first trimester of pregnancy. Serious adverse events occur following high dose and prolonged administration of these drugs for treatment of echinococcosis or neurocysticercosis, especially in patients with poor liver function. The adverse events may be induced by the drugs, or by the dead worms themselves. The Korea Institute of Drug Safety & Risk Management monitors drug-related adverse events in Korea, and its database included 256 probable or possible ADZ-associated events and 108 PZQT-associated events between 2006 and 2015. Such low incidence rates in Korea are due to the low single dose treatments of ADZ, and the short-term use of PZQT. The number of serious adverse events due to drug interaction induced by ADZ and PZQT were six and two, respectively. We conclude that ADZ and PZQT are generally safe drugs, but they must be used with caution in people with poor liver function or those being comedicated for gastroesophageal reflux disease.
