PREGNANCY-ASSOCIATED OSTEOPOROSIS IS A RA RE CLINICAL ENTITY - 2 NEW CASES

Two women, 31 and 19 years old, developed acute back pain with non-tra umatic vertebral fractures one month after delivery in one case, and d uring the 9th month of gestation in the second case. For the first pat ient, the evolution was favorable with an increase of bone mineral den sity (15.2% over fourteen months under calcium and vitamin D). Ten yea rs later, the osteoporosis of the second patient worsened without any new pregnancy. Our observations suggest the possibility of different p athogenies in pregnancy-associated osteoporosis.
