Importance of planning ovulation induction therapy in systemic lupus erythematosus and antiphospholipid syndrome: a single center retrospective study of 21 cases and 114 cycles

Antiphospholipid syndrome in systemic lupus erythematosus: is the whole greater than the sum of its parts?

This article compares the manifestations of systemic lupus erythematosus (SLE) in the presence and absence of antiphospholipid antibodies (aPLs), the hallmark autoantibodies of antiphospholipid syndrome (APS). The combination of SLE and APS appears to be of greater concern than either entity alone. APS complicates SLE by adding a vaso-occlusive factor to the inflammatory component that adversely affects the prognosis of those who have lupus and aPLs. The increase in both morbidity and mortality when both are present has significant therapeutic implications. Anticoagulation may be a safer and more appropriate therapeutic option than instituting a regimen of corticosteroids and immunosuppressive agents with all their attendant adverse effects. It falls upon the physician to clearly define the disease entity and fully evaluate the disease process.

Making pregnancy safer for patients with lupus

Systemic lupus erythematosus is a hormone-dependent disorder predominantly affecting young women in whom changes in hormonal activity affect the course of the disease. More specifically, pregnancy is associated in 50 to 60% of cases with a clinical flare manifesting as renal or hematological symptoms, usually during the second or third trimester but occasionally in the postpartal period. Patients should be strongly advised to start a pregnancy only if their disease has been stable for at least 6 months, and they should be informed of the few contraindications. Severe flares are uncommon (10%) and the risk of maternal death is now 2 to 3%. The risk of the fetus remains high, however. Thus, fetal loss is common, particularly in patients with a lupus anticoagulant, renal failure, or arterial hypertension. Preterm birth occurs in 25% to 50% of cases and intrauterine growth retardation in 30%. Neonatal lupus with or without congenital heart block is exceedingly rare, being seen in the 1% of SLE women who have anti-SSA (Ro) and/or SSB (La) antibodies. To ensure a favorable outcome for both the mother and the child, the pregnancy should be planned, started during a period of disease stability, monitored closely (physical examination, laboratory tests, and Doppler ultrasound), and treated as needed (with antimalarial therapy throughout the pregnancy). Even with these precautions, however, preterm birth remains common.

Undiagnosed Systemic Lupus Erythematosus in a Cohort of Infertile Women

PROBLEM

Systemic lupus erythematosous (SLE) is a chronic disease with a broad spectrum of clinical and immunological manifestations, therefore, this condition may be frequently misdiagnosed. The current study was conducted to determine the prevalence of undiagnosed SLE among a cohort of infertile women.

METHOD OF STUDY

Screening was performed using sequential (two stage) testing, which included a self-completed questionnaire followed by an antinuclear antibody (ANA) test. The Liang screening questionnaire was distributed to 143 consecutive infertile patients, aged 24-42 years (mean, 33.6 +/- 4.7 years), who were receiving in-vitro fertilization (IVF) treatment. Patients who completed the questionnaire with three or more positive answers, were sent for ANA testing; those who tested positive (>or=1:40) were referred to the Clinical Immunology Unit for anti-double-stranded DNA (dsDNA) antibody test and clinical assessment.

RESULTS

A total of 136 women (95.1%) completed the questionnaire. Thirteen patients (9.6%) answered yes to three or more questions. Of these, five patients (3.7%) were ANA-positive and two (1.5%) had undiagnosed SLE.

CONCLUSIONS

A 1.5% prevalence of undiagnosed SLE was found in our cohort of infertile women. Additional investigations should be performed as to the role of SLE screening in infertile female population; a high-risk group with regard to ovulation induction treatments.

New insights into pregnancy-related complications in systemic lupus erythematosus

Pregnancy in patients with systemic lupus erythematosus (SLE) presents an additional risk to an already complex clinical situation--overlap in symptoms between changes of pregnancy and SLE, presence of antiphospholipid antibodies, and need for potentially teratogenic medications can all complicate the management of pregnant patients with SLE. Studies demonstrate that, with careful planning, the majority of patients with lupus can complete pregnancy without serious complications. Recent developments are modified instruments to measure disease activity in pregnancy, increasingly common continuation of hydroxychloroquine during pregnancy, more frequent use of in vitro fertilization, and more aggressive fetal monitoring in patients positive for anti-Sjögren's syndrome (SS)-A/Ro or anti- SS-B/La antibody.
