GARCIA LIZASO, Humberto y GARCIA GARCIA, Yudith. Clinical characteristics and management of macroprolactinemia as cause of hyperprolactinemia. Rev Cubana Obstet Ginecol [online]. 2018, vol.44, n.1, pp. 1-11. ISSN 1561-3062.
Macroprolactinemia is defined as the presence of high quantities of this prolactin isoform in serum, together with normal concentrations of monomeric prolactin. It is a common entity, considered among the three first causes of hyperprolactinaemia. The origin seems to respond to autoimmune mechanisms and the affected patients follow-up during ten years periods has shown that it is a chronic condition. The standard gold test to the diagnostic is gel-filtration chromatography, but it is an expensive method that is generally supplied by the polyethylene glycol precipitation test. During a long time, the concept that these patients are essentially asymptomatic has prevailed, but recent reports stamps the presence of hyperprolactinemia symptoms as a significant part of the entity, although current literature shows divergent criteria. In these patients, performing pituitary magnetic resonance seems to be an unnecessary procedure, based on the rare frequency of positive results. Pharmacological treatment with dopamine agonists shows contradictory responses with regard to symptoms disappearance and prolactin levels normalization. Therefore, the lack of consensus in the scientific literature with regard to the clinical manifestations and the management, requires a convenient individual assessment of each case.
