Central nervous system lupus and pregnancy: 11-year experience at a single center

OBJECTIVE

To describe the pregnancy outcomes in women with central nervous system (CNS) manifestations of lupus.

METHODS

Between 1991 and 2002, the outcome of five pregnancies in four patients with CNS lupus were retrospectively reviewed. All patients had an established history of systemic lupus erythematosus (SLE), and either a history of CNS lupus or active CNS lupus. Pregnancy outcomes assessed included term and preterm birth, intrauterine growth restriction, abnormal antepartum testing, perinatal mortality, pre-eclampsia and other maternal morbidities.

RESULTS

Evidence of active CNS lupus symptoms developed in three of the five pregnancies. Two pregnancies were complicated by early onset pre-eclampsia, abnormal antepartum testing and extreme prematurity, with one subsequent neonatal death. The remaining three pregnancies had good neonatal outcomes, but were complicated by severe maternal post-pregnancy exacerbations, and the eventual death of one patient.

CONCLUSIONS

CNS lupus in pregnancy represents an especially severe manifestation of SLE, and may involve great maternal and fetal risks.

Psychosocial correlates of morbidity in women with systemic lupus erythematosus

OBJECTIVE

Modifiable psychosocial factors that are associated with health outcomes may provide new opportunities for treatment. We investigated the associations of various psychosocial factors with 3 measures of morbidity in women with systemic lupus erythematosus (SLE).

METHODS

We collected information on 16 social, psychological, behavioral, and medical care factors in a cross sectional survey of 100 women with SLE, and related these to measures of physical disability (assessed by the Health Assessment Questionnaire Disability Index), SLE activity (assessed by the Systemic Lupus Activity Measure), and cumulative organ damage (assessed by the SLICC/ACR Damage Index).

RESULTS

In multivariate analyses, greater physical disability was significantly associated with higher depression scale scores and higher body mass indexes. Greater SLE activity was associated with less adequate social support. Greater cumulative organ damage was associated with lower self-esteem and a time orientation that favored the present over the future. Financial barriers to medical care, knowledge about SLE, health locus of control, marital status, and health behaviors including compliance with medications, smoking, alcohol use, and exercise, were not significantly associated with any measure of morbidity.

CONCLUSION

Selected psychosocial factors are associated with morbidity in SLE, but differ with the measure of morbidity examined.

Socioeconomic status and health in women with systemic lupus erythematosus

OBJECTIVE

Health outcomes of patients with chronic illnesses are commonly worse in people of lower socioeconomic status (SES). We investigated psychosocial factors that may mediate the relationship between SES and measures of morbidity in women with systemic lupus erythematosus (SLE).

METHODS

We collected information on SES, psychosocial factors, and health status in a cross sectional survey of 100 women with SLE. SES was rated using the Hollingshead Two-Factor Index, a weighted average of years of formal education and occupational prestige (higher Hollingshead Index=lower SES). Health status measures included the Health Assessment Questionnaire Disability Index (HAQ), the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR), the Systemic Lupus Activity Measure (SLAM), and the SLE Disease Activity Index (SLEDAI). Potential mediators consisted of 18 environmental, medical care, social, psychological, and behavioral factors.

RESULTS

Patients with higher Hollingshead Indexes (lower SES) had more functional disability as measured by the HAQ (r=0.22: p=0.03) and more cumulative organ damage as measured by the SLICC/ACR Damage Index (r = 0.19; p=0.06). SES was not related to either the SLAM or SLEDAI. Significant univariate associations were present between the Hollingshead Index and 10 potential mediating variables: household crowding, insurance status, organizational barriers to medical care, depression, health locus of control by powerful others, SLE knowledge, social support, marital status, body mass index, and regular alcohol use. However, in multiple linear regression analyses, only 3 of these variables modified the relationship between Hollingshead Index and the HAQ: more severe depression scores, higher body mass index, and more restricted access to medical care. More severe depression and greater locus of control by powerful others tended to mediate the relationship between low SES and greater organ damage.

CONCLUSION

SES is related to morbidity in women with SLE. There are identifiable and potentially modifiable mediators of this relationship.

Pregnancy complicated by primary antiphospholipid antibody syndrome

BACKGROUND

Primary antiphospholipid antibody syndrome is a clinical entity that may threaten the health of both fetus and mother.

CASE

We report a fatal case of primary antiphospholipid antibody syndrome in a woman who developed catastrophic disease due to multisystem thrombosis in the postpartum period following a fetal death. Three years before her admission, primary antiphospholipid antibody syndrome was diagnosed on the basis of high titers of immunoglobulin G anticardiolipin antibody, a positive lupus anticoagulant, a false-positive VDRL, and fibrin deposits in the biopsy of a palmar lesion.

CONCLUSION

The physician must recognize the potentially catastrophic complications of pregnancy and the postpartum period in patients with antiphospholipid antibodies, and appropriate patient counseling should be provided.

Pneumocystis carinii pneumonia complicating low dose methotrexate treatment for rheumatoid arthritis

Low dose methotrexate has been used effectively for various rheumatic and non-rheumatic diseases. Three cases of Pneumocystis carinii pneumonia occurring during treatment of rheumatoid arthritis with low dose methotrexate are presented. Several mechanisms might contribute to impaired immunity and the rare development of opportunist lung infection with methotrexate. A high degree of suspicion may result in earlier diagnosis and treatment.
