RESUMEN
To reveal which disease activity parameters affect low Apgar scores of newborns, which is considered as a predictive parameter for neurological development.We examined retrospectively the data from 42 newborns who were delivered from systemic lupus erythematosus (SLE) mothers from 2006 to 2019. We evaluated whether the disease activity parameters, such as the achievement ratio of lupus low disease activity state (LLDAS), SLE disease activities index (SLEDAI), complement level, titer of anti-double stranded DNA (anti-dsDNA) antibody, therapeutic agents were related with low Apgar scores of newborns.In 42 newborns, adverse pregnancy outcomes, especially preterm birth (16.7%), low birth weight (31.0%) light-for-date (11.9%) were associated with disease activity parameters or prednisolone dose. Apgar scores at 1 minute were related with unachieved LLDAS and the titer of anti-dsDNA antibody at first and third trimester, SLEDAI score and complement level at third trimester, mean prednisolone dose. Apgar scores at 5 minutes were also associated with the titer of anti-dsDNA antibodies at first and third trimester and mean prednisolone dose. Multivariate analysis showed only high titer of anti-dsDNA antibody was significantly associated with low Apgar score at both one minute and 5 minutes.In our retrospective study, high titer of anti-dsDNA antibodies at first and third trimester was a risk factor for low Apgar scores of newborns born to SLE mothers. We considered that high titer of anti-dsDNA antibody influenced on childrens neurological development, therefore, there is a need for long-term follow-up study of SLE offsprings.
