Neuroleptic malignant syndrome (NMS), a potentially fatal consequence due to typical neuroleptics, has been described so far. In the past few years, there has been increased use of atypical antipsychotic drugs. Cases of NMS related to atypical neuroleptics, such as olanzapine, are less common in spite of increasing cases reported in literatures. Here, we report a case of NMS in a patient with bipolar affective disorder on maintenance treatment with 5 mg olanzapine for the last 7 year. He was successfully treated with bromocriptine and discharged in stable condition in 10 days...

Despite the androgenic dependence, other hormones, growth factors, and cytokines are necessary to support prostatic growth and maintain the glandular structure; among them, prolactin is a non-steroidal hormone secreted mainly by the pituitary gland. However, extra-pituitary expression of prolactin, such as in the prostate, has also been demonstrated, highlighting the paracrine and autocrine actions of prolactin within the prostate. Here, we investigated whether prolactin modulation alters ventral prostate (VP) morphophysiology in adult castrated rats...

Using a spontaneous mouse model of obsessive-compulsive disorder (OCD), the current study evaluated the influence of postpartum lactation on the expression of compulsive-like behaviors, SSRI effectiveness, and the putative role of oxytocin and dopamine in mediating these lactation specific behavioral outcomes. Compulsive-like lactating mice were less compulsive-like in nest building and marble burying and showed enhanced responsiveness to fluoxetine (50 mg/kg) in comparison to compulsive-like nonlactating and nulliparous females...

Prolactin (PRL) and oxytocin (OT) are pituitary hormones essential for lactation, but also promote sexual behavior. OT stimulates social behaviors, such as recognition, approach, and learning, but less is known about PRL in these behaviors. Since PRL and OT have complementary functions in reproduction, we hypothesized that PRL increases social recognition, approach, and learning. Male Long-Evans rats received ovine PRL (oPRL; 0.5, 2.0 or 5.0mg/kg), the PRL antagonist bromocriptine (0.1, 3.0 or 5.0mg/kg) or saline 20 mins before testing for recognition of familiar vs...

Aims: An anti-angiogenic cleaved prolactin fragment is considered causal for peripartum cardiomyopathy (PPCM). Experimental and first clinical observations suggested beneficial effects of the prolactin release inhibitor bromocriptine in PPCM. Methods and results: In this multicentre trial, 63 PPCM patients with left ventricular ejection fraction (LVEF) ≤35% were randomly assigned to short-term (1W: bromocriptine, 2.5 mg, 7 days) or long-term bromocriptine treatment (8W: 5 mg for 2 weeks followed by 2...

Although somatostatin analogues (SSAs) are recommended as the first-line medical therapy for acromegaly, dopamine agonists (DAs) are also a therapeutic option for treatment. We aimed to assess and compare the efficacies of DAs and SSAs in treating acromegaly in clinical practice. We included 89 patients with acromegaly who took DAs (bromocriptine [BCT], n = 63; cabergoline [CAB], n = 11) or SSAs (n = 15) as a primary medical therapy for more than 3 months in the Seoul National University Hospital. The CAB (45...

Spontaneous eye blink rate (EBR) has been proposed as a noninvasive, inexpensive marker of dopamine functioning. Support for a relation between EBR and dopamine function comes from observations that EBR is altered in populations with dopamine dysfunction and EBR changes under a dopaminergic manipulation. However, the evidence across the literature is inconsistent and incomplete. A direct correlation between EBR and dopamine function has so far been observed only in nonhuman animals. Given significant interest in using EBR as a proxy for dopamine function, this study aimed to verify a direct association in healthy, human adults...

Prolactin-producing uterine leiomyomas are very rare. Although hyperprolactinemia rapidly improves after removal of such leiomyomas, no preoperative diagnostic test has been established for prolactin-producing uterine leiomyomas. A 45-year-old Japanese woman, gravida 3 para 3, was referred to our hospital for further examination of hyperprolactinemia resistant to a dopamine agonist. A pituitary prolactinoma was undetectable by brain magnetic resonance imaging. A bromocriptine loading test revealed an increased serum prolactin concentration after loading...

The discovery of neuropeptides provides insights into the regulation of physiological processes. The precursor for the neuropeptide neuromedin U contains multiple consensus sequences for proteolytic processing, suggesting that this precursor might generate additional peptides. We performed immunoaffinity chromatography of rat brain extracts and consequently identified such a product, which we designated neuromedin U precursor-related peptide (NURP). In rat brain, NURP was present as two mature peptides of 33 and 36 residues...

There is increasing evidence associating idiopathic granulomatous mastitis (IGM) with hyperprolactinemia. All documented cases have involved the patient having at least one operative procedure before the association has been made. We present a 55 year old female with IGM associated with risperidone induced hyperprolactinemia. She was successfully treated with a dopamine agonist, bromocriptine. We demonstrated that complete resolution can be achieved without surgical intervention, by targeting serum prolactin levels...

Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy presenting with heart failure due to left ventricular systolic dysfunction towards the end of pregnancy or in the months following delivery, where no other cause of heart failure is found. We report a case of a woman with PPCM who developed a critical cardiogenic shock with repeated cardiopulmonary resuscitation. We show for the first time that mechanical circulatory support combined with high-dose bromocriptine therapy to suppress systemic prolactin levels may serve as an effective therapeutic option in patients with fulminant PPCM and cardiogenic shock...

Maternal stress is associated with negative health consequences for both the mother and her offspring. To prevent these adverse outcomes, activity of the hypothalamic-pituitary-adrenal (HPA) axis is attenuated during pregnancy and lactation. While the mechanisms generating this adaptive change have not been fully defined, the anterior pituitary hormone prolactin may play a significant role. This study investigated the role of prolactin in regulating the basal activity of the HPA axis during pregnancy and lactation in the mouse, focussing upon the corticotropin-releasing hormone (CRH) neurons...

Rheumatoid arthritis (RA) is a chronic autoimmune disease that affects females three times more frequently than males. A potential role for hormones, such as prolactin (PRL), may in part explain this phenomenon. The risk of developing RA is increased in women who are lactating after the first pregnancy, which might be related to breastfeeding and the release of PRL. Other studies found a protective effect of PRL on RA development. Some studies have reported that hyperprolactinemia is more common in RA and serum PRL levels are correlated with several disease parameters, although others could not confirm these findings...
