Hyperprolactinemia has been reported in some patients with active systemic lupus erythe matosus (SLE). To determine if there was an association between selected autoantibodies and hyperprolactinemia, we assayed prolactin concentrations in sera from women sub mitted to a reference antinuclear antibody laboratory. Autoantibody-positive samples were separated into groups that contained antibodies to double-stranded DNA (anti-DNA), anti bodies to SSA/Ro (anti-SSA/Ro), or antibodies to both SSA/Ro and SSB/La (anti-SSA/Ro- SSB/La). Results were compared with autoantibody-negative sera from age-matched women, submitted to the same laboratory. We also compared the study groups with a separate cohort of 84 healthy women who were not referred for autoantibody testing. Elevated prolactin levels were clustered in 20% of sera from anti-DNA-positive women This study confirmed the reported associations of hyperprolactinemia with SLE and Sjögren's syndrome. Multiple factors appeared to contribute to elevated serum prolactin levels in women with connective tissue diseases, and the presence of hyperprolactinemia was related to unique findings on immunoblot analysis.

50 years of age. Twenty-one percent of anti-SSA/Ro-SSB/La-positive women < 50 years of age were hyperprolactinemic. Four of the 15 hyperprolactinemic women identified in this survey had no known cause of elevated prolactin. In the other 11 individuals, secondary causes such as hypothyroidism, pregnancy, chronic renal failure, and medications may have accounted for high serum prolactin values. We also examined sera by Western blot, to determine if immunoblot patterns were associated with elevated serum prolactin concentra tions. The hyperprolactinemic sera yielded novel bands migrating at 70 kd, 32 kd, and 16.5 kd.
