Multicenter Study
Systemic lupus erythematosus in three ethnic groups. XII. Risk factors for lupus nephritis after diagnosis.
The purpose of this study was to determine the cumulative incidence of lupus nephritis (LN) and the factors predictive of its occurrence in a multiethnic systemic lupus erythematosus (SLE) cohort. We studied 353 SLE patients as defined by the American College of Rheumatology (ACR) criteria (65 Hispanics, 93 African-Americans and 91 Caucasians). First, we determined the cumulative incidence of LN in all patients. ⋯ Repeated analyses excluding the patients with missing HLA data showed that absence of HLA-DQB1*0201 was also a significant predictor for the occurrence of LN (OR = 2.34, CL = 1.13-5.26, P < 0.04). In conclusion, LN occurred significantly more often in Hispanics and African-Americans with SLE. Sociodemographic, clinical and immunologic/immunogenetic factors seem to be predictive of LN occurring after the diagnosis of SLE has been made.

Case Reports
Management of pregnancy in women with pulmonary hypertension secondary to SLE and anti-phospholipid syndrome.
Pulmonary hypertension is found in about 10% of patients with systemic lupus erythematosis (SLE). Pulmonary hypertension may be present at the time of diagnosis or may develop after the diagnosis of SLE or anti-phospholipid syndrome (APS). It often presents in the reproductive years and has a significant impact on pregnancy outcome, being a significant cause of indirect maternal deaths. ⋯ The patient received multidisciplinary care from the first trimester and the management of the pregnancy, delivery and the early puerperium was planned. Careful epidural anaesthesia was used and the patient had invasive monitoring on the intensive therapy unit (ITU) for 72 hours. Women with pulmonary hypertension need to be aware of the high risk of maternal mortality associated with pregnancy but we believe that an improvement in outcome can be achieved by careful assessment and the use of a multidisciplinary approach from early in pregnancy.
