Long-term assessment of patients with macroprolactinemia
Fertility and Sterility, 1988Three patients presenting with hyperprolactinemia associated with normal menses, retained fertility, and minimal lactation were followed for a period of 5 to 7 years. All had associated thyroid autoimmune disorders (one with chronic thyroiditis and two with Graves' disease).

[Macroprolactinemia in a child].
Archives francaises de pediatrie, 1991An hyperprolactinemia, with basal serum prolactin levels ranging from 41 to 135 ng/ml was found to be coincidentally associated with psychosocial dwarfism in a 11 year-old boy. Sephadex G 100 exclusion chromatography showed that the predominating form of immunoreactive prolactin levels ranging from 41 to 135 ng/ml was found to be weight, differing from

Macroprolactinemia presenting like a pituitary tumor
The American Journal of Medicine, 1985A serum prolactin level greater than 200 ng/ml is almost pathognomonic of a pituitary tumor in a nonpregnant woman. A patient with a three-year history of documented serum prolactin levels of 350 to 400 ng/ml and no evidence of a pituitary adenoma on computed axial tomographic scanning was recently studied.

Macroprolactinemia in Patients With Prolactinomas: Prevalence and Clinical Significance
Experimental and Clinical Endocrinology and Diabetes, 2013Data on the prevalence of macroprolactinemia in patients with prolactinomas is quite limited as the presence of high-molecular prolactin forms is suspected mainly in subjects with mild hyperprolactinemia and negative pituitary imaging.The main objective of this observational case-control study was to assess the prevalence and clinical significance of ...

Macroprolactinemia. Is treatment necessary?
Hormones (Athens, Greece), 2007A 26-year old symptom-free woman was admitted to our Clinic for evaluation of hyperprolactinemia. The patient, who had normal menstrual cycles, was found accidentally to have a cystic adnexal mass and was placed on oral contraceptives (OC) for 3 months.

Macroprolactinemia as the cause of elevated serum prolactin in men
The American Journal of Medicine, 1989Arecently described cause of hyperprolactinemia is production of a circulating prolactin species with chemical and biologic properties different from native prolactin (macroprolactin) [l-7]. Patients with macroprolactin have been described as females, with regular menstrual periods, preserved fertility, and absence of pituitary abnormalities on ...

[An immunologic etiology for hyperprolactinemia: macroprolactinemia].
Revue medicale de Liege, 1999Besides classical etiologies of hyperprolactinaemia (pregnancy, pharmacological treatments, pituitary or hypothalamic perturbations), another less known cause may explain a spectacular idiopathic elevation of plasma concentrations of prolactin hormone.

[Macroprolactinemia identification in patients with hyperprolactinemia].
Ginecologia y obstetricia de Mexico, 2008Macroprolactinemia is defined as hyperprolactinemia with predominance of the big-big prolactine isoform. Its frequency has not been clearly established due to technical difficulties to identify it. This method used to detect it is gel filtration chromatography, an expensive and complicated procedure that could not be used routinely.To validate the PEG ...

[Macroprolactinemia in the differential diagnosis of hyperprolactinemia].
Orvosi hetilap, 2004Biologically active prolactin and the inactive fraction of macroprolactin can be present in hyperprolactinaemic sera. The reaction of routinely used prolactin assays with macroprolactin is variable.The present study was undertaken to analyse the leading clinical signs of hyperprolactinemia in macroprolactinemia and true hyperprolactinemia and to assess
