- Objective: To determine the frequency, clinical characteristics, associations, and outcomes of different types of peripheral nervous system (PNS) disease in a multiethnic/multiracial, prospective inception cohort of systemic lupus erythematosus (SLE) patients. Methods: Patients were evaluated annually for 19 neuropsychiatric (NP) events including 7 types of PNS disease. SLE disease activity, organ damage, autoantibodies, and patient and physician assessment of outcome were measured. Time to event and linear regressions were used as appropriate. Results: Of 1,827 SLE patients, 88.8% were female, and 48.8% were white. The mean ± SD age was 35.1 ± 13.3 years, disease duration at enrollment was 5.6 ± 4.2 months, and follow-up was 7.6 ± 4.6 years. There were 161 PNS events in 139 (7.6%) of 1,827 patients. The predominant events were peripheral neuropathy (66 of 161 [41.0%]), mononeuropathy (44 of 161 [27.3%]), and cranial neuropathy (39 of 161 [24.2%]), and the majority were attributed to SLE. Multivariate Cox regressions suggested longer time to resolution in patients with a history of neuropathy, older age at SLE diagnosis, higher SLE Disease Activity Index 2000 scores, and for peripheral neuropathy versus other neuropathies. Neuropathy was associated with significantly lower Short Form 36 (SF-36) physical and mental component summary scores versus no NP events. According to physician assessment, the majority of neuropathies resolved or improved over time, which was associated with improvements in SF-36 summary scores for peripheral neuropathy and mononeuropathy. Conclusion: PNS disease is an important component of total NPSLE and has a significant negative impact on health-related quality of life. The outcome is favorable for most patients, but our findings indicate that several factors are associated with longer time to resolution.

- Objectives Adverse pregnancy outcomes are more common in women with SLE compared with healthy women, but we lack prognostic biomarkers. Plasma IFN-alpha protein levels are elevated in a subgroup of pregnant women with SLE, but whether this is associated with pregnancy outcomes is unknown. We investigated the relationship between IFN-alpha, adverse pregnancy outcomes and the presence of autoantibodies in SLE pregnancy.Methods We followed 76 women with SLE prospectively. Protein levels of IFN-alpha were quantified in plasma collected in the second and third trimester with single-molecule array. Positivity for ANA and aPL antibodies was assessed during late pregnancy with multiplexed bead assay. Clinical outcomes included the adverse pregnancy outcomes small for gestational age (SGA), preterm birth and preeclampsia.Results During SLE pregnancy, women with SGA infants compared with those without had higher levels of plasma IFN-alpha protein, and IFN-alpha positivity was associated with lower birth weight of the infant. Preterm birth was associated with autoantibodies against chromatin. IFN-alpha protein levels associated positively with autoantibodies against chromatin, Smith/RNP (SmRNP) and RNP, but negatively with aPL antibodies.Conclusion Elevated IFN-alpha protein in plasma of women with SLE is a potential risk factor for lower birth weight of their infants. The association between IFN-alpha and lower birth weight warrants further investigation regarding the pathophysiological role of IFN-alpha during SLE pregnancy. Graphical Abstract
