Maternal Near Miss in Patients with Systemic Lupus Erythematosus
Abstract Introduction: Systemic lupus erythematosus (SLE) may cause irreversible organ damage. Pregnancy with coexisting SLE may have severe life-threatening risks. Severe maternal morbidities (SMM) include maternal death, maternal near miss (MNM), and potentially life-threatening conditions (PLTC). This study aimed to determine the prevalence of SMM in patients with SLE and analyze the parameters that contributed to cases of greater severity. Methods: This is a cross-sectional retrospective study from analysis of data retrieved from medical records of pregnant women with SLE treated at São Paulo Hospital , Brazil, from 2005 to 2015. The pregnant women were divided in control group without complications, group with PLTC, and group with MNM. Results: Out of 149 pregnancies, there were 14 cases of MNM (9.4%), 56 cases of PLTC (37.6%), and no maternal death. The maternal near miss rate was 112.9 per 1,000 live births. The majority of PLTC (83.9%) and MNM (92.9%) cases had preterm deliveries with statistically significant increased risk compared with control group [p=0.0042; OR (95% CI): 12.05 (1.5-96.6) for MNM group and p=0.0001; OR (95% CI): 4.84 (2.2-10.8) for PLTC group]. SMM increases the risk of longer hospitalization [p<0,0001; OR (95% CI): 18.8 (7.0-50.6) and p <0.0001; OR (95% CI): 158.17 (17.6-1424,2) for PLTC and MNM, respectively], newborns with low birth weight [p=0.0006; OR (95% CI): 3.67 (1.7-7.9) and p=0.0009; OR (95% CI): 17.68 (2-153.6) for PLTC and MNM group, respectively] as well as renal diseases [PLTC (58.9%, 33/56; p = 0.0069) and MNM (78.6%, 11/14; p = 0.0026)]. MNM cases presented increased risk for neonatal death [p=0.0128; OR (95% CI): 38.4 (3.3-440.3)], stillbirth and miscarriage [p=0.0011; OR (95% CI): 7.68 (2.2-26.3)]. Conclusion: SLE was significantly associated with severe maternal morbidity, longer hospitalizations, and increased risk of poor obstetric and neonatal outcomes, such as prematurity, neonatal death, miscarriage and fetal loss.
