UNASSIGNED: To evaluate serum prolactin and macroprolactin levels in patients on long-term proton pump inhibitors therapy.
METHODS: The cross-sectional study was conducted from January 2018 to November 2019 after approval from the ethics review committee of the Commission on Science and Technology for Sustainable Development in the South University, Abbottabad, Pakistan. The study included patients from two gastroenterology outpatient clinics in the Khyber Pakhtunkhwa province using proton pump inhibitors for ≥3 months either alone or in combination with either histamine receptor antagonists or prokinetics. Blood samples were collected from each patient for hormonal screening. Data was analysed using SPSS 25.
RESULTS: Of the 166 patients, 101(60.8%) were females and 65(39.2%) were males. The overall mean age was 42.5±14.2 years, and the median serum prolactin level was 23.2ng/ml (interquartile range: 14.0-38.0ng/ml). There were 96(58%) patients with normoprolactinaemia and 70(42%) with hypreprolactinaemia. There were 19(11.4%) patients using combination therapy, while the rest were on proton pump inhibitors monotherapy. There was a significant increase in serum prolactin level with combination therapy compared to monotherapy (p=0.001). Patients having treatment duration 11-20 months (p=0.006) and >40 months (p=0.001) were at high risk of developing hyperprolactinaemia.
CONCLUSIONS: Long-term use of proton pump inhibitors could increase serum prolactin levels, and appropriate evaluation is essential for clinical management.

BACKGROUND: Pulmonary embolism (PE) is a severe and life-threatening complication of venous thromboembolism. However, there is a lack of systematic studies on differences between female and male PE patients. This paper aimed to compare the sex-specific differences in clinical characteristics and laboratory indicators in psychotic patients with PE.
METHODS: This retrospective study enrolled psychiatric patients with PE from June 2018 to June 2022 at Shenzhen Kangning Hospital (Shenzhen Mental Health Center). Demographic characteristics, factors associated with PE, and laboratory indices were collected to assess sex-specific differences.
RESULTS: Of the 168 patients, 87 (51.8%) were female and 81 (48.2%) were male, with a mean age of 58 years for females and 46 years for male patients. The male group had higher ratio of hyperprolactinemia, more patients using antipsychotic medications, higher D-dimer levels at PE onset, greater D-dimer difference, and a higher rate of D-dimer elevation than the female group (p < 0.05). Female patients were significantly older, exhibited a higher prevalence of diabetes, and had a greater number of patients taking antidepressants and hypnotics/sedatives than male patients (p < 0.05). Schizophrenia spectrum disorders were more prevalent in male patients, while female patients had a higher incidence of mood disorders (p < 0.05). Among patients aged < 45 years, the male group had higher D-dimer levels at PE onset and greater D-dimer difference (p < 0.05). Among all 112 patients aged ≥ 45 years, male patients were more likely than female patients to have respiratory tract infections, higher D-dimer levels at PE onset, greater D-dimer difference, and a higher rate of D-dimer elevation (p < 0.05). The multiple linear regression analysis indicated that hyperprolactinemia and the use of first-generation antipsychotics (FGAs) were associated with D-dimer levels at PE onset in male patients, while the time of PE onset and protective restraints were associated with D-dimer levels at PE onset in female patients (p < 0.05).
CONCLUSIONS: PE-associated clinical features differ between male and female patients. These differences may imply that the processes and mechanisms of PE onset are sex specific. Male patients are more likely to have respiratory tract infections and higher D-dimer levels at PE onset than female patients. The use of FGAs may be associated with increased D-dimer in male psychiatric patients, while protective restraints may be associated with increased D-dimer in female psychiatric patients.

Background and Objectives: Hyperprolactinemia, as a potential side-effect of some antipsychotic medications, is associated with decreased bone density and an increased risk of fractures. This study investigates whether calcium and vitamin D supplementation affects prolactin receptor (Prlr) gene expression in the duodenum, vertebrae, and kidneys of female rats with sulpiride-induced hyperprolactinemia. Materials and Methods: Twenty-one-week-old female Wistar rats were assigned to three groups: Group S consisted of ten rats who received sulpiride injections (10 mg/kg) twice daily for 6 weeks; Group D (10 rats) received daily supplementation of 50 mg calcium and 500 IU vitamin D along with sulpiride for the last 3 weeks; and Group C consisting of seven age-matched nulliparous rats serving as a control group. Real-time PCR was used to assess Prlr gene expression in the duodenum, vertebrae, and kidneys. Results: In Group S, Prlr gene expression was notably decreased in the duodenum (p < 0.01) but elevated in the vertebrae and kidneys compared to Group C. Conversely, Group D exhibited significantly increased Prlr expression in the duodenum (p < 0.01) alongside elevated expression in the vertebrae and kidneys. Conclusions: In sulpiride-induced hyperprolactinemia, decreased Prlr gene expression in the duodenum may lead to reduced intestinal calcium absorption. Consequently, prolactin may draw calcium from the skeletal system to maintain calcium balance, facilitated by increased Prlr gene expression in the vertebrae. However, vitamin D supplementation in sulpiride-induced hyperprolactinemia notably enhances Prlr gene expression in the duodenum, potentially ameliorating intestinal calcium absorption and mitigating adverse effects on bone health.

The objective of this study is to conduct a bibliometric analysis of research trends in hyperprolactinemia from 2011 to 2023. This analysis aims to provide researchers with insights into the current hotspots and frontiers related to hyperprolactinemia. It is worth noting that there are currently no existing reports on bibliometric analyses of hyperprolactinemia. The Social Science Citation Index (SSCI) and Science Citation Index Expanded (SCIE) databases of the Web of Science Core Collection were systematically searched for \"articles\" and \"review articles\" related to the topic of hyperprolactinemia from 2011 to 2023. VOSviewer was employed to conduct bibliometric analysis, aiming to analyze the research trends in hyperprolactinemia over the past 13 years. A total of 1865 eligible articles were retrieved, with contributions from 9544 scholars representing 83 countries in the field of research. The United States had the highest number of publications, followed by China. The keywords were categorized into six clusters: (1) etiology of hyperprolactinemia and other related endocrine and metabolic diseases. (2) Hyperprolactinemia and mental illness. (3) Diagnosis and management of hyperprolactinemia. (4) Treatment of hyperprolactinemia and prolactinoma. (5) Detection of macroprolactin and macroprolactinemia. (6) Symptoms of male hyperprolactinemia. Over the past 13 years, there has been a consistent and slightly increasing trend in the number of research papers focusing on hyperprolactinemia. The primary areas of research focus are centered around the diagnosis and treatment of hyperprolactinemia caused by antipsychotic drugs or prolactinoma.

UNASSIGNED: The risk of venous thromboembolism in patients with mental illness has been insufficiently addressed. This study aimed to assess the correlation between hyperhomocysteinemia and venous thromboembolism prevalence among this population.
UNASSIGNED: Patients with a diagnosis of mental illness and concurrent venous thromboembolism, admitted to Sir Run Run Shaw Hospital at Zhejiang University School of Medicine between January 2014 and December 2021, were included in the venous thromboembolism group. The control group, approximately twice the size, comprised individuals with mental illness but without venous thromboembolism. Basic clinical data were gathered for both cohorts.
UNASSIGNED: In psychiatric patients, elevated D-dimer levels(OR=5.60,95% CI 3.28-10.00), hyperhomocysteinemia (OR=2.37,95% CI 1.10-5.14), and hyperprolactinemia(OR= 2.68,95% CI 1.12-6.42)were significant risk factors for venous thromboembolism. According to further subgroup analyses, hyperhomocysteinemia is a significant risk factor associated with pulmonary embolism, with an OR of 5.08 (95% CI 1.20-21.48). An interaction effect between gender and homocysteine level was found, with a p-interaction of 0.022. A subsequent analysis confirmed the association between hyperhomocysteinemia and venous thromboembolism in female psychiatric patients, with an OR of 3.34 (95% CI 1.68-6.65), indicating that hyperhomocysteinemia is a significant risk factor for venous thromboembolism in women.
UNASSIGNED: Patients with psychiatric disorders were found to have an elevated risk of venous thromboembolism, which was associated with increased levels of D-dimer, hyperprolactinemia, and hyperhomocysteinemia. A strong correlation between hyperhomocysteinemia and pulmonary embolism was identified in patients with mental illnesses. Furthermore, the study revealed that female psychiatric patients with hyperhomocysteinemia constituted a high-risk group for venous thromboembolism. This finding holds significant clinical implications, suggesting that early preventative measures could be implemented for this high-risk population to reduce the incidence of thromboembolic events during hospitalization for psychiatric patients.

Hyperprolactinemia is an endocrinological disorder that might arise from various physiologic or pathologic conditions, as well as from pharmacologic sources. These pharmacologic sources include antidepressants, antipsychotics, and dopamine receptor-blocking agents. Amitriptyline is classified as a tricyclic antidepressant. While it is FDA-approved primarily for the treatment of depression, amitriptyline also demonstrates efficacy in managing various other conditions, such as anxiety, post-traumatic stress disorder, insomnia, chronic and neuropathic pain, and migraine prevention. We present a case of a 10-year-old patient with a history of autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and migraine headaches who was incidentally found to have elevated prolactin levels while taking amitriptyline for migraine prophylaxis. While risperidone, an antipsychotic that can be used for ASD management, is commonly known to induce hyperprolactinemia, the association between amitriptyline and elevated prolactin is less frequently described in the literature. This case underscores the necessity for healthcare providers across various specialties to be aware of amitriptyline-induced hyperprolactinemia.

This paper aims to study the therapeutic effect and safety of Bushen Culuan Formula in the treatment of patients with infertility caused by hyperprolactinemia. Sixty patients with infertility caused by hyperprolactinemia of kidney deficiency and blood stasis were divided into the treatment group(Bushen Culuan Formula + Bromocriptine Mesylate Tablets placebo) and the control group(Bromocriptine Mesylate Tablets + Bushen Culuan Formula placebo), and ovulation rate, pregnancy rate, serum sex hormones, basal body temperature(BBT), and traditional Chinese medicine(TCM) symptom scores were observed. The results showed the clinical effective rate was 90.00% in the treatment group and 80.00% in the control group. The treatment group was able to significantly reduce the PRL level and increase the pregnancy rate, and it was superior to the control group in increasing the BBT biphasic ratio, improving the TCM symptom scores, and enhancing the ovulation rate. The results show that Bushen Culuan Formula is safe and reliable in treating ovulatory disorder infertility caused by hyperprolactinemia, with remarkable effects.

Transcriptomics was used to investigate the mechanism of action of Bushen Culuan Formula in the treatment of infertility caused by hyperprolactinemia(HPRL), and animal experiments were carried out to verify the results. After establishing an animal model of HPRL-induced infertility, the mice were divided into normal group, model group, Bushen Culuan Formula groups with high-, medium-, and low-doses, and bromocriptine group, and they were observed in terms of the estrous cycle, gonadal index, serum sex hormones, morphology of ovary and mammary gland, follicle count, and fertility. The results showed that the Bushen Culuan Formula could effectively restore the estrous cycle, down-regulate the levels of prolactin(PRL), follicle-stimulating hormone(FSH), and luteinizing hormone(LH), up-regulate the level of estradiol(E_2), increase the number of primordial follicles and sinus follicles, and improve the ovulation rate and fertility of mice. Through RNA sequencing combined with biosignature analysis, Bushen Culuan Formula may regulate the metabolism of lipids, antioxidant enzymes, and other substances in the cells of the ovary and pituitary gland through the signaling pathways of cAMP-PKA, Kiss-1/GPR54, and Hippo and exert therapeutic effects. The results of animal experiments showed that Bushen Culuan Formula could up-regulate serum dopamine(DA) level and pituitary DRD2 expression, down-regulate hypothalamus and ovary cAMP levels, as well as protein expressions of the pituitary gland and ovary PKA, CREB, and p-CREB, and treat HPRL-induced infertility by regulating the cAMP-PKA signaling pathway.

BACKGROUND: Hyperprolactinemia accompanies growth hormone hypersecretion in approximately 25-39% of cases. There is a recommendation to determine the level of prolactin in clinical guidelines for diagnosis and treatment of acromegaly. However, there is no understanding of the necessity to investigate the IGF-1 level in patients with hyperprolactinemia and a pituitary adenoma.
OBJECTIVE: Determining the proportion of patients with hyperprolactinemia and pituitary adenoma, who were examined for IGF-1 levels, and identifying the proportion of patients with acromegaly among this cohort.
METHODS: Between December 2019 and December 2022 a single-center observational single-stage single-sample uncontrolled study was conducted. At the first stage of the study, the proportion of patients with pituitary adenoma and hyperprolactinemia with studied IGF-1 levels was determined, according to medical records. At the second stage of the study, patients without known indicators of IGF-1 were determined. The concentration of growth hormone was studied during the oral glucose load in the case of increased IGF-1 levels.
RESULTS: At the first stage, 105 patients were included in the study. The level of IGF-1 was determined in 41/105 (39%) cases. There were 22/41 (53.7%) cases in the subgroup with pituitary incidentalomas and 19/64 (29.7%) cases in the subgroup with hyperprolactinemia among them. At the second stage, the IGF-1 level was additionally determined in 53 patients with hyperprolactinemia and pituitary adenoma (total 94 patients). The level of IGF-1 was elevated in 11/94 patients, further acromegaly was confirmed in 3/94 patients (3.2%).
CONCLUSIONS: In real clinical practice the level of IGF-1 is studied only in 39% of cases in patients with pituitary adenoma and hyperprolactinemia. The disease was detected in 3 cases (3.2%) out of 94 people with hyperprolactinemia and pituitary adenoma without clinical manifestations of acromegaly. We consider the study of IGF-1 levels justified as a screening for acromegaly in patients with hyperprolactinemia and pituitary adenoma.
