Hydrocortisone treatment of BCG-infected mice impairs the activation and enhancement of antimicrobial activity of peritoneal macrophages.

The present study concerns the effect of hydrocortisone (HC) on the effector functions of Bacillus Calmette Guerin-purified protein derivative (BCG-PPD)-activated macrophages. Such activated macrophages release greater amounts of H2O2 and NO2-, inhibit the intracellular proliferation of T. gondii and kill L. monocytogenes more efficiently than resident macrophages. This activation was not fully expressed by macrophages from BCG-activated mice that had received a subcutaneous injection of HC 2 days before intraperitoneal injection of PPD, since the inhibition of the intracellular proliferation of T. gondii, the release of NO2- and the rate of intracellular killing of L. monocytogenes were lower than in macrophages from BCG-PPD-activated mice. However, treatment with HC did not impair the release of H2O2 by BCG-PPD-activated macrophages. The results show that the treatment of infected mice with HC inhibits their ability to develop adequate intracellular microbicidal mechanisms.

Seizures associated with oxamniquine therapy.

Three patients who were treated for schistosomiasis mansoni with oxamniquine suffered generalized seizures. We suggest that this side effect may be more common than previously reported. Specific ethnic groups may be particularly at risk.
