PEARLS FROM THE CASES - 1 Anthrax during pregnancy can be successfully managed as in nonpregnant women Clinical progression of the anthrax is similar to nonpregnant women Prompt clinical suspicion and rapid administration of effective antimicrobials are essential.

PEARLS FROM THE CASES - 2 Penicillin is still the drug of choice in the theraphy of anthrax during pregnancy High dose prednisolone therapy may be beneficial Preterm delivery could be expected Increased plasma volume of pregnancy should be taken into consideration in the dosing of antibiotics

PEARLS FROM THE CASES - 3 In these cases, the evaluation of preterm delivery would be worthwhile; - It was at the end of the anthrax therapy -Sudden onset of preterm delivery -Unresponsiveness to tocolysis -Occurence without PROM

PEARLS FROM THE CASES - 4 We may also be interest on the effects of high dose prednisolone therapy: -Clinical outcome reducing mortality ??? -Pregnancy outcome delaying pretem delivery ??? -Benefits to newborn Reducing RDS and ventricular hemorrhage
