In the article titled “Maternal and Perinatal Outcome in Women with Systemic Lupus Erythematosus: A Retrospective Bicenter Cohort Study” [1], the authors identified some discrepancies in the data following its publication.

There are very small changes in incidence of HELLP syndrome (N = 5 instead of N = 7), preeclampsia (N = 22 instead of 24), and mild hypertensive disorder (N = 19 instead of 21), which showed no significant difference in the preeclampsia group. The incidence of preeclampsia <34 weeks, eclampsia, and HELLP syndrome were too low to conduct the generalized estimating equations (GEE) analysis; therefore, a new p value cannot be produced. Due to the very small differences, we believe that our conclusions are not changed. As already described on page 6 of the article: “In our cohort, we only found an association with APS and HELLP. However, considering the low numbers of HELLP in the paper by Moroni et al. (2 out of 71 pregnancies = 2.6%) and our study (7 out of 144 pregnancies = 4.9%), we do not venture to interpret these findings.”

The corrected Table 3 is shown below.

Table 3.

Maternal and perinatal pregnancy complications in all study pregnancies.

Total SLE-aPL SLE + aPL SLE + APS p value
Maternal complications N = 144 N = 117 N = 14 N = 13
Mild HD 19/144 (13.2) 16/117 (13.7) 1/14 (7.1) 2/13 (15.4) ns
Severe HD 24/144 (16.7) 18/117 (15.4) 2/14 (14.3) 4/13 (30.8) ns
 Preeclampsia 22/141 (15.6) 17/114 (14.9) 2/14 (14.3) 3/13 (23.1) ns
 Onset preeclampsia <34 weeks 8/22 (36.4) 7/17 (41.2) 1/3 (33.3) 0 (0)
 Eclampsia 1/140 (0.7) 1/113 (0.9) 0/14 (0) 0/13 (0)
 HELLP syndrome 5/144 (3.5) 3/117 (2.6) 0/14 (0) 2/13 (15.4)
Perinatal complications n = 147 n = 119 n = 15 n = 13
IUFD 6/147 (4.1) 6/119 0/15 0/13 ns
Preterm birth 48/147 (32.7) 40/119 (33.6) 4/15 (26.7) 4/13 (30.8) ns
SGA infant 21/142 (14.8) 18/115 (15.7) 2/15 (13.3) 1/12 (8.3) ns
Neonatal lupus 2/147 (1.4) 2/119 (1.7) 0/15 (0) 0/13 (0) ns

Additionally, in Section 3.3.2, the sentence “Of all preterm births (<37 weeks), 44.2% occurred spontaneously, and in the others, labour was induced. Main indications for preterm induction of labour (<37 weeks) were HD (54.1%) and IUFD (12.5%).” should be corrected to “Of all preterm births (<37 weeks), 61.9% occurred spontaneously. Main indications for preterm induction of labor (<37 weeks) were HD (30.8%) and IUGR (23.1%). IUFD as reason for preterm induction of labor occurred once (7.7%).”

Also, the email address of the corresponding author should be changed to “s.kroese@hagaziekenhuis.nl.”

The authors confirm that this does not affect the results and conclusions of the article, and the editorial board agrees to the publication of a corrigendum.
