Objective: Prolactin is an essential hormone secreted by the pituitary gland of pregnant women. The pituitary gland undergoes growth, due to lactotroph hyperplasia in response to placental estrogen during pregnancy. Research on the postpartum outcomes of prolactinomas is less. This study evaluates the prevalence of Prolactinoma and the occurrence of spontaneous resolution of Prolactinomas after pregnancy.
Materials and Methods: A cross-section study was conducted at the Punjab Institute of Neurosciences, Lahore. 200 pregnant women were recruited; their blood samples were collected to evaluate serum prolactin levels. Women diagnosed with prolactinomas exhibiting positive symptoms were given dopamine agonists. The administration of dopamine agonist was discontinued at the 24th week of gestation. All participants were monitored till birth, at 40 days after delivery, and throughout breastfeeding. Their prolactin levels were evaluated, and magnetic resonance imaging (MRI) was conducted to verify the resolution of prolactinoma.
Results: The mean age of females in the study was 29.03 ± 7.20 years. Out of 200, 40 (20%) females had prolactinoma. Out of 40, 13 (32.5%) were given Bromocriptine while 27 (67.5%) were given Cabergoline. At presentation, the mean serum prolactin level was 138.91 ± 149.02 ng/ml, which reduced to 21.38 ± 9.80 ng/ml. The mean tumor size at presentation was 7.23 ± 2.07 mm, which reduced to 0.79 ± 0.66 mm after delivery. Out of 40, 30 (75.0%) had spontaneous resolution.
Conclusion: The occurrence of prolactinoma is low in symptomatic patients and can resolve spontaneously after delivery in the majority of cases.
