Sjögren's syndrome and pregnancy

Area of Science:

• Rheumatology
• Obstetrics
• Immunology

Background:

• Sjögren's syndrome (SS) is a chronic autoimmune disease.
• Pregnancy outcomes in women with SS require further investigation.
• Understanding the impact of SS on pregnancy is crucial for patient care.

Purpose of the Study:

• To investigate pregnancy outcomes in patients with Sjögren's syndrome.
• To identify factors associated with adverse pregnancy outcomes in SS patients.
• To compare pregnancy outcomes in SS patients with and without systemic lupus erythematosus (SLE).

Main Methods:

• Analysis of 117 pregnancy histories from 40 female patients with SS.
• Comparison of SS patient outcomes with a control group of 129 healthy women.
• Assessment of the association between antibodies (anti-SS-A, anti-SS-B) and pregnancy complications.

Main Results:

• No significant difference in spontaneous abortion rates for overall SS or primary SS compared to controls.
• Significantly higher rates of spontaneous abortions and premature deliveries in SS patients with co-existing SLE.
• No association found between anti-SS-A/anti-SS-B antibodies and pregnancy outcomes.
• Increased spontaneous abortions in secondary SS patients with specific serological/hematological abnormalities (e.g., lupus anticoagulants).
• No congenital anomalies or connective tissue disease observed in neonates.

Conclusions:

• Sjögren's syndrome alone does not generally impact pregnancy outcomes.
• Pregnancy outcomes are adversely affected in SS patients with co-existing SLE.
• Specific serological and hematological abnormalities in SS patients may indicate increased risk for spontaneous abortions.
