To assess the frequency of hyperprolactinemia and evaluate its possible clinical significance in patients with systemic lupus erythematosus (SLE). We determined serum prolactin (PRL) levels in 30 patients with SLE by a radioimmunometric assay. For each patient, the clinical disease activity was assessed using the Systemic Lupus Activity Measure. Antinuclear antibodies were determined by standard techniques. Correlation between PRL concentrations and SLE clinical and serological activity were evaluated. Elevated serum concentrations of PRL (>25 ng/ml in female and >16 ng/ml in male) were found in 10 of the 30 (33.3%) patients (7-85 ng/ml, mean 33.8, SD 19.8). A significant correlation was found between the PRL levels and the clinical disease activity of SLE (P < 0.001, r = 0.675). In addition, hyperprolactinemia was associated with serological activity. Hyperprolactinemia was frequently detected in patients with SLE. There is a significant correlation between hyperprolactinemia and lupus activity.

UI	MeSH Term	Description	Entries
D006966	Hyperprolactinemia	Increased levels of PROLACTIN in the BLOOD, which may be associated with AMENORRHEA and GALACTORRHEA. Relatively common etiologies include PROLACTINOMA, medication effect, KIDNEY FAILURE, granulomatous diseases of the PITUITARY GLAND, and disorders which interfere with the hypothalamic inhibition of prolactin release. Ectopic (non-pituitary) production of prolactin may also occur.

D008180	Lupus Erythematosus, Systemic	A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

D011388	Prolactin	A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.

D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
