Levodopa‐refractory hyperprolactinemia and pituitary findings in inherited disorders of biogenic amine metabolism

Journal of Inherited Metabolic Disease, Volume 47, Issue 3, Page 431-446, May 2024.
Abstract Elevated serum prolactin concentrations occur in inherited disorders of biogenic amine metabolism because dopamine deficiency leads to insufficient inhibition of prolactin secretion. This work from the International Working Group on Neurotransmitter Related Disorders (iNTD) presents the results of the first standardized study on levodopa ...

Macroprolactin over time: Is there any point in rechecking it in people with a persistently elevated serum prolactin?

Clinical Endocrinology, Volume 100, Issue 5, Page 450-458, May 2024.
Abstract Objective and Design Macroprolactinemia may influence the interpretation of serum prolactin levels—a recognised phenomenon since 1981. The degree of macroprolactinaemia over time is less well described. We determined how macroprolactin status (based on polyethylene glycol (PEG) precipitation) varied by analysing serial measurements in ...

Detection of macroprolactinemia and molecular characterization of prolactin isoforms in blood samples of hyperprolactinemic women [PDF]

Journal of Medical Biochemistry, 2012
Prolactin (PRL) circulates in the blood in the form of monomeric prolactin, dimeric prolactin and macroprolactin. Macroprolactin is a common cause of hyperprolactinemia.

Macroprolactinemia Associated with Anti-Prolactin Antibodies: A Case Report

Endocrinology Research and Practice, 2022
Macromolecular form of prolactin is generally associated with asymptomatic hyperprolactinemia. Increases in molecular size may result from self-aggregation or binding with antiprolactin antibodies.

Contemporary approaches to the diagnosis of hyperprolactinemia

Репродуктивная эндокринология, 2019
Hyperprolactinemia (HP) is a persistent prolactin increase in serum. HP is a common endocrinopathy that impairs reproductive function, long term HP may lead to the metabolic disorders and a decrease in bone mineral density.
