El síndrome neuroléptico maligno es una condición clínica rara y potencialmente letal que frecuentemente se asocia con el uso de antipsicóticos. En la literatura especializada se encontró únicamente un reporte de caso relacionado con la ingestión de organofosforados. Se presenta un paciente con un cuadro clínico correspondiente al síndrome neuroléptico maligno posterior a la ingestión de clorpirifós. Como resultado de un intento de suicidio con el mencionado organofosforado, el hombre de 57 años presentó deterioro agudo del estado de consciencia, evolución neurológica tórpida e inestabilidad autonómica asociada a rigidez e hipertermia persistentes, así como incremento de la creatina-fosfocinasa (creatine phosphokinase, CPK). Se le administró tratamiento con bromocriptina, con lo cual el cuadro clínico remitió, y fue dado de alta sin secuelas. El diagnóstico del síndrome neuroléptico maligno es clínico y debe contemplarse en cualquier caso de exposición a sustancias que puedan resultar en una desregulación de la neurotransmisión dopaminérgica, con el fin de iniciar el tratamiento oportuno y contrarrestar efectivamente los efectos.
Neuroleptic malignant syndrome is a rare and potentially fatal clinical condition frequently associated with the use of antipsychotics. In the literature, there is only one case report associated with the intake of organophosphates. We present the case of a patient who presented with a clinical picture compatible with neuroleptic malignant syndrome, after the ingestion of an organophosphate (chlorpyrifos). A 57-year-old man who consulted for attempted suicide, acute deterioration of consciousness, torpid neurological evolution, and associated autonomic instability associated with rigidity, persistent hyperthermia, and elevated CPK. Bromocriptine treatment was offered, which resolved the clinical picture. The association with the ingestion of an organophosphate was established, and he was discharged without sequelae. The diagnosis of neuroleptic malignant syndrome is clinical and should be considered in any case of exposure to substances that may lead to dysregulation of dopaminergic neurotransmission in order to initiate timely therapy and impact outcomes.

ABSTRACT Prolactinomas are the most common pituitary adenomas (approximately 40% of cases), and they represent an important cause of hypogonadism and infertility in both sexes. The magnitude of prolactin (PRL) elevation can be useful in determining the etiology of hyperprolactinemia. Indeed, PRL levels > 250 ng/mL are highly suggestive of the presence of a prolactinoma. In contrast, most patients with stalk dysfunction, drug-induced hyperprolactinemia or systemic diseases present with PRL levels < 100 ng/mL. However, exceptions to these rules are not rare. On the other hand, among patients with macroprolactinomas (MACs), artificially low PRL levels may result from the so-called "hook effect". Patients harboring cystic MACs may also present with a mild PRL elevation. The screening for macroprolactin is mostly indicated for asymptomatic patients and those with apparent idiopathic hyperprolactinemia. Dopamine agonists (DAs) are the treatment of choice for prolactinomas, particularly cabergoline, which is more effective and better tolerated than bromocriptine. After 2 years of successful treatment, DA withdrawal should be considered in all cases of microprolactinomas and in selected cases of MACs. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) is to provide a review of the diagnosis and treatment of hyperprolactinemia and prolactinomas, emphasizing controversial issues regarding these topics. This review is based on data published in the literature and the authors' experience.

Surgery, anticoagulation therapy, pregnancy, and hormone treatments, such as bromocriptine, are well-characterized precipitating factors for pituitary apoplexy. However, whether cytotoxic chemotherapy for systemic cancer could cause pituitary apoplexy has not been investigated. Here, we present a case of a 41-year-old woman who developed a severe headache with decreased visual acuity after intravenous cytotoxic chemotherapy to treat metastatic breast cancer. Preoperative neuroimaging revealed pituitary adenoma with necrosis. Operative findings and pathologic examination concluded extensive necrosis with a small intratumoral hemorrhage in a pre-existing pituitary adenoma. We reviewed two additional previously published cases of pituitary apoplexy after systemic chemotherapy and suggest that cytotoxic chemotherapy may induce pituitary apoplexy.

A cabergolina e a bromocriptina são drogas dopaminérgicas derivadas do ergot e utilizadas para tratamento de distúrbios hiperprolactinêmicos idiopáticos ou adenomas hipofisários, cujo mecanismo de ação é decorrente da redução da secreção de prolactina. Alguns relatos na literatura demonstram que a cabergolina pode causar valvopatia após sua administração a longo prazo. Relatamos o caso de um paciente com diagnóstico de macroprolactinoma que fez uso intercalado de cabergolina e bromocriptina e desenvolveu alterações valvares antes inexistentes

PURPOSE: Prolactinoma (prolactin-secreting pituitary adenoma) is one of the most common estrogen-related functional pituitary tumors. As an agonist of the dopamine D2 receptor, bromocriptine is used widely to inhibit prolactinoma progression. On the other hand, it is not always effective in clinical application. Although a dopamine D2 receptor deficiency contributes to the impaired efficiency of bromocriptine therapy to some extent, it is unknown whether there some other underlying mechanisms leading to bromocriptine resistance in prolactinoma treatment. That is the main point addressed in this project. MATERIALS AND METHODS: Human prolactinoma samples were used to analyze the S-phase kinase associated protein 2 (SKP2) expression level. Nutlin-3/adriamycin/cisplatin-treated GH3 and MMQ cells were used to analyze apoptosis in SKP2 overexpression or knockdown cells. SKP2 expression and the interaction partners of SKP2 were also detected after a bromocriptine treatment in 293T. Apoptosis was analyzed in C25 and bromocriptine-treated GH3 cells. RESULTS: Compared to normal pituitary samples, most prolactinoma samples exhibit higher levels of SKP2 expression, which could inhibit apoptosis in a p53-dependent manner. In addition, the bromocriptine treatment prolonged the half-life of SKP2 and resulted in SKP2 overexpression to a greater extent, which in turn compromised its pro-apoptotic effect. As a result, the bromocriptine treatment combined with C25 (a SKP2 inhibitor) led to the maximal apoptosis of human prolactinoma cells. CONCLUSION: These findings indicated that SKP2 inhibition sensitized the prolactinoma cells to bromocriptine and helped promote apoptosis. Moreover, a combined treatment of bromocriptine and C25 may contribute to the maximal apoptosis of human prolactinoma cells.

<p><b>PURPOSE</b>Despite the prevalence and cost of traumatic brain injury related disabilities, there is paucity in the literature on modern approaches to pharmacotherapy. Medications may promote recovery by enhancing some neurological functions without impacting others. Herein we discussed the role of bromocriptine in neurorehabilitation for patients with traumatic brain injury.</p><p><b>METHODS</b>A cohort comprising of 36 selective nonsurgical cases of traumatic brain injury in minimally conscious state were enrolled in the study. After hemodynamic stability, bromocriptine was given at paediatric dose of 3.75 mg/d and adult dose of 7.5 mg/d. It was administered through a naso-gastric (NG) feeding tube in the patients with minimally conscious state, then changed to oral route after proper swallowing and good gag reflex were ensured in the patient. The drug was slowly reduced over three weeks after neurological improvement in the patients. Positive result was determined by improved GCS score of 2 and motor power by at least 1 British Medical Council (BMC) motor score. Improvement of deficits was evaluated in terms of fluency of speech for aphasia, task switching, digit span double tasking and trail-making test for cognition and attention, and functional independence measure score for motor functioning and self-independence.</p><p><b>RESULTS</b>Accelerated arousal was seen in 47.0% of cases (8/17) in 4-40 days. In 41.2% of cases (7/17), Glasgow outcome score (GOS) was improved to 4/5 in 90 days. Improvement in hemiparesis by at least 1 BMC score was seen in 55.6% of cases (5/9) in 40 days. Aphasia was improved in 80% of cases (4/5) in 7-30 days. Moderate improvement in cognitive impairment was seen in 66.7% of cases (2/3) in 14-20 days. Improvement in memory was observed in 50% of cases (1/2) in over 30 days. No cases were withdrawn from the study because of adverse reactions of the drug. There was no mortality in the study group.</p><p><b>CONCLUSION</b>Bromocriptine improves neurological sequelae of traumatic brain injury as well as the overall outcome in the patients. If medication is given to promote recovery and treat its associated disabilities, clinicians should thoroughly outline the goals and closely monitor adverse effects.</p>

ABSTRACT Objetive The aim was to assess the evolution of tumor size and prolactin (PRL) levels in patients with micro and macroprolactinomas diagnosed and treated with dopamine agonists during fertile age, and the effects of suspension of drugs after menopause. Retrospective study, 29 patients with prolactinomas, 22 microadenomas and 7 macroadenomas, diagnosed during their fertile age were studied in their menopause; treatment was stopped in this period. Age at menopause was 49 ± 3.6 years. The average time of treatment was 135 ± 79 months. The time of follow-up after treatment suspension was 4 to 192 months. Results Pre-treatment PRL levels in micro and macroadenomas were 119 ± 57 ng/mL and 258 ± 225 ng/mL, respectively. During menopause after treatment suspension, and at the latest follow-up: in microadenomas PRL levels were 23 ± 13 ng/mL and 16 ± 5.7 ng/mL, respectively; in macroadenomas, PRL levels were 20 ± 6.6 ng/mL 5t5and 25 ± 18 ng/mL, respectively. In menopause after treatment suspension, the microadenomas had disappeared in 9/22 and had decreased in 13/22. In the group of patients whose tumor had decreased, in the latest follow-up, tumors disappeared in 7/13 and remained unchanged in 6/13. In macroadenomas, after treatment suspension 3/7 had disappeared, 3/7 decreased and 1/7 remained unchanged. In the latest control in the 3 patients whose tumor decreased, disappeared in 1/3, decreased in 1/3 and there was no change in the remaining. Conclusions Normal PRL levels and sustained reduction or disappearance of adenomas were achieved in most of patients, probably due to the decrease of estrogen levels. Dopamine agonists might be stopped after menopause in patients with prolactinomas.

Antipsychotics are the drug of choice for patients with schizophrenia, but they can induce hyperprolactinemia and growth of pituitary adenomas by blocking dopamine 2 receptors in the pituitary gland. In contrast, the medical treatment for a prolactinoma is a dopamine agonist. Therefore, managing a patient concurrently diagnosed with a prolactinoma and psychosis is challenging. We describe a patient with schizophrenia who was diagnosed with a prolactinoma. We changed his neuroleptic to quetiapine and prescribed bromocriptine for the prolactinoma. As a result, the patient was successfully treated with a dopamine agonist and antipsychotic without psychotic exacerbation. Our case suggests that dopamine agonists can be administrated to patients with schizophrenia and a prolactinoma without adversely affecting their psychopathological status.

Physiologic pituitary enlargement is common during normal pregnancy. However, symptoms such as diplopia, blurred vision and headache resulting from physiologic pituitary enlargement are very rare during pregnancy. A 39-year-old woman complained of sudden diplopia and left eye ptosis at 33th weeks of gestation. An magnetic resonance imaging (MRI) demonstrated the pituitary enlargement compressing the optic chiasm. Notwithstanding the medication of bromocriptine, her symptoms did not regress during pregnancy. At 5 months after delivery, her symptoms dramatically resolved without any surgery, and her visual acuity was normalized. Her MRI scan also revealed more decreased size of pituitary gland compared to antenatal MRI. We report a case of visual loss due to the physiologic pituitary enlargement of nonfunctioning adenoma during pregnancy, which regressed spontaneously after delivery without any surgery.

Background: Dopamine agonists (DA) effectively reduce tumor size of macroprolactinomas, with the consequent improvement of eventual visual impairment. Aim: To study the visual outcomes in patients with macroprolactinoma treated with DA. Material and Methods: Retrospective cohort study which included patients with macroprolactinoma controlled at a Neuro-endocrinology and Neuro-ophthalmology Department between 1997'and2011, and treated exclusively with DA (bromocriptine or cabergoline). Patients who were operated or had previous radiotherapy and those with an incomplete follow up, were excluded. We analyzed and compared the visual status before and after the beginning of DA treatment. Results: Thirty one patients aged 8 to 59years, were included. Eighteen patients (58%) had visual impairment at the moment of diagnosis (group 1) and 13 had no alterations (group 2). Mean follow up was 36.5 months. Fifteen patients from group 1 (83%) had visual improvement, two remained stable (11 %) and one had a visual deterioration (6%). In group 2, only one non-compliant patient had a visual deterioration. Conclusions: DAs are effective in the management of neuro-ophthalmic complications associated to macroprolactinomas and should be considered asfirst choice therapy in these tumors.

Bromocriptine is a potent agonist at the D2 receptor. The aim of this study is to investigate the bromocriptine effect in spontaneous motor activity, using variable doses with acute and subacute administration and variable onset of measurement using albino mice. Acute intraperitoneal administration of bromocriptine using doses of 0.625, 2.5, 5, and 10mg/kg and the control group administration of 1% tween 80[n=7] were used. Spontaneous motor activity was scored after 30 and 60min of administration. Subacute administration is as follows: group1was administered 1% tween 80asa control and group2 was administered 10mg/kg bromocriptine. Spontaneous motor activity was scored using an open field test. Acute administration of bromocriptine after 30 min [0.625 and 2.5mg/kg] did not show any significant changes in spontaneous motor activity while 5 and 10mg/kg produced a significant decrease. Acute administration of bromocriptine after 60min produced a significant decrease in spontaneous motor activity, with 0.625, 2.5, 5, and 10mg/kgdoses. Subacute administration of bromocriptine significantly increased spontaneous motor activity, compared to control. It is concluded that acute administration of bromocriptine at 30 min decreased spontaneous motor activity, only with higher doses while its acute administration after 60 min decreased spontaneous motor activity, with all doses [0.625, 2.5, 5, and 10mg/kg]. As subacute administration increased spontaneous motor activity, these findings conclude that bromocriptine which produced its effect in spontaneous motor activity is time and dose dependence.

Psoriasis is a T-cell mediated hyperproliferative cutaneous disease of multifactorial etiology. Prolactin [PRL] has been implicated in the pathogenesis of psoriasis and several studies have pointed to a potential therapeutic role of bromocriptine in psoriasis. To assess the clinical efficacy of bromocriptine and the influence of serum prolactin levels on disease severity in patients with chronic plaque-type psoriasis. Forty-five patients with chronic plaque-type psoriasis and 45 healthy control subjects were included in the study. The patients were divided into three equal groups; a group treated with narrow-band ultraviolet B [NB-UVB], a group treated with bromocriptine, and a group treated with both NB-UVB and bromocriptine. Serum PRL levels and psoriasis area severity index [PASI] scores were measured before and after a 12-week treatment period. There was no significant difference in the serum PRL levels between the patients prior to treatment and the controls. Correlations between PASI scores and serum PRL levels before and after treatment were insignificant. Post-treatment PASI scores were significantly lower than pretreatment values in each of the treated groups. Post-treatment serum PRL levels were significantly lower in both groups receiving bromocriptine than the group receiving NB-UVB alone, they were also significantly lower in the group treated with NB-UVB and bromocriptine than the group treated with bromocriptine alone. Bromocriptine may be of value in the treatment of chronic plaque-type psoriasis in the absence of hyperprolactinemia. NB-UVB may have an additive effect to bromocriptine on serum PRL levels

Neuroleptic malignant syndrome (NMS) is a severe iatrogenic complication of treatment with antipsychotic medication. The aim of this review is to provide the clinical characteristics and treatments of children and adolescents with NMS. Searches were conducted in Medline, Korean studies Information Service System (KISS), and Research Information Service System (RISS). Sixteen case reports and two review articles were selected in Medline, and two Korean cases reported in department of emergency medicine and pediatrics were selected from RISS. Heterogeneous and atypical presentations of NMS were observed in children and adolescents. Some noticeable differences were observed between adult patients and child patients with NMS. In addition, symptom presentations related to atypical antipsychotic agents differed from those of typical ones. In treatment, bromocriptine and benzodiazepine were recommended for management of symptoms. In particular, electroconvulsive therapy (ECT) was a useful treatment option. For prevention and early detection of NMS in children and adolescents, evaluation of risk factors and understanding of diagnostic features of NMS are very important.

Bruxism is a diurnal or nocturnal parafunctional activity that includes tooth clenching, bracing, gnashing, and grinding. The dopaminergic system seems to be the key pathophysiology of bruxism and diminution of dopaminergic transmission at the prefrontal cortex seems to induce it. We report two patients with diurnal bruxism in whom a bilateral frontal lobe injury resulted from hemorrhagic stroke or traumatic brain injury. These patients' bruxism was refractory to bromocriptine but responded to low-dose metoclopramide therapy. We propose that administering low doses of metoclopramide is possibly a sound method for treating bruxism in a brain injury patient with frontal lobe hypoperfusion on positron emission tomography imaging.

Lactating adenoma is a benign breast disease that occurs during pregnancy or lactational periods. Here we report on a case of rapidly enlarging lactating adenoma in a 28-year-old postpartum woman, which was mistaken for a malignant breast tumor. Treatment with bromocriptine resulted in a rapid reduction of the mass, suggesting that bromocriptine could be used for shrinking lactating adenoma and to facilitate surgical removal. We describe its imaging findings, including ultrasonographic findings with correlative histologic features, confirmed by surgical excision.

OBJECTIVE: The objective of this study was to describe and characterize the clinical course of treatment for invasive prolactinoma patients using bromocriptine. METHODS: The study group included 23 patients who were treated with bromocriptine for their invasive prolactinomas. Clinical histories, serum prolactin level and pituitary hormone assessments, tumor diameter and signal intensity on sella magnetic resonance imaging (MRI), visual field exams and the dosage of medications were reviewed for each patient. RESULTS: During 30 months (median, range 6-99) of follow-up period, 19 patients treated with bromocriptine alone achieved biochemical remission. Four patients changed the medication to cabergoline due to the adverse effects or observed resistance of bromocriptine treatment. All of five patients who had visual symptoms improved after the course of medication. Four surgically treated patients were not able to discontinue medication because they could not maintain biochemical remission state without medication. Multivariate analysis showed that decreased enhancement on the initial followed MRI after medication and longer follow-up periods were associated with higher radiologic response. CONCLUSION: We reassure that the dopamine agonist is safe and effective for the treatment of invasive pituitary adenomas. Meanwhile, surgery has a limited role on biochemical remission. Decreased enhancement on the initial follow-up MRI after medication may reflect the treatment response. Further study is required to validate the role of MRI or other factors on the actual prognosis.
