Survival rate as a function of gestational age at the inaugural acute phase of TTP in 108 patients
| . | iTTP (n = 50)∗ . | uTTP (n = 27) . | cTTP (n = 29) . | Total (N = 106) . |
|---|---|---|---|---|
| First trimester | 4/8 (50.0%) | 1/1 (100.0%) | 1/2 (50.0%) | 6/11 (54.5%) |
| Second trimester | 3/11 (27.2%) | 0/5 (0.0%) | 3/9 (33.3%) | 6/25 (24.0%) |
| Third trimester | 19/22 (86.4%) | 15/16 (93.8%) | 14/15 (93.3%) | 48/53 (90.6%) |
| Postpartum | 9/9 (100.0%) | 5/5 (100.0%) | 3/3 (100.0%) | 17/17 (100.0%) |

The results are presented as number of live births per number of pregnancies (survival rate). Trimesters and postpartum refer to pregnancies complicated by a TTP episode: first trimester, before 15 WG; second trimester, between 16-28 WG; and third trimester, after 28 WG but before birth.
There was no significant association between the subtype of TTP and the survival rate. The second trimester is significantly associated with lower survival rate (P < .0001).
Two pregnancies were ended (abortion) and are therefore not reported in this table.
