A randomized controlled clinical trial of prazosin for alcohol use disorder in active duty soldiers: Predictive effects of elevated cardiovascular parameters. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2023; 47:348-360. [PMID: 36809662 DOI: 10.1111/acer.14989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 10/23/2022] [Accepted: 11/23/2022] [Indexed: 02/24/2023]
Abstract
BACKGROUND Excessive noradrenergic signaling contributes to aversive symptoms of alcohol withdrawal that interfere with abstinence or reductions in harmful use. METHODS To address this aspect of alcohol use disorder, 102 active-duty soldiers participating in command-mandated Army outpatient alcohol treatment were randomized to also receive the brain-penetrant alpha-1 adrenergic receptor antagonist prazosin or placebo for 13 weeks. Primary outcomes were scores on the Penn Alcohol Craving Scale (PACS), standard drink units (SDUs) per day averaged over each week, % days of any drinking per week, and % days of heavy drinking per week. RESULTS PACS declines did not differ significantly between the prazosin and placebo groups in the overall sample. In the subgroup with comorbid PTSD (n = 48), PACS declines were significantly greater in the prazosin than in the placebo condition (p < 0.05). Baseline alcohol consumption was markedly reduced by the pre-randomization outpatient alcohol treatment program, but the addition of prazosin treatment produced a greater slope of decline in SDUs per day compared to placebo (p = 0.01). Preplanned subgroup analyses were performed in soldiers with elevated baseline cardiovascular measures consistent with increased noradrenergic signaling. In soldiers with elevated standing heart rate (n = 15), prazosin reduced SDUs per day (p = 0.01), % days drinking (p = 0.03), and % days heavy drinking (p = 0.001) relative to placebo. In soldiers with elevated standing systolic blood pressure (n = 27), prazosin reduced SDUs per day (p = 0.04) and tended to reduce % days drinking (p = 0.056). Prazosin also reduced depressive symptoms and the incidence of emergent depressed mood more than placebo (p = 0.05 and p = 0.01, respectively). During the final 4 weeks of prazosin vs. placebo treatment that followed completion of Army outpatient AUD treatment, alcohol consumption in soldiers with elevated baseline cardiovascular measures increased in those receiving placebo but remained suppressed in those receiving prazosin. CONCLUSIONS These results extend reports that higher pretreatment cardiovascular measures predict beneficial effects of prazosin, which may be useful for relapse prevention in patients with AUD.

Abstract
BACKGROUND Ectopic ACTH-dependent Cushing syndrome is rarely caused by pheochromocytoma (PCC). Glucocorticoid-regulated positive feedback loops in ACTH and catecholamines were proposed in some similar cases. CASE PRESENTATION We present here an 80-year-old man who had previously undergone surgery for a left adrenal PCC and newly developed severe hypertension, hypokalemia, and typical Cushingoid manifestations. Investigations revealed hyperglycemia, hypokalemia, and extremely high catecholamines and their metabolites, ACTH and cortisol. Imaging modalities showed a recurrent large left adrenal mass positively visualized with 123I-metaiodobenzylguanidine as well as somatostatin receptor scintigraphy. Surgical interventions were not indicated; thus, metyrapone, phentolamine, and doxazocin were initiated, which successfully controlled his symptoms and biochemical conditions. With the evidence that metyrapone administration decreased ACTH and catecholamine levels, the existence of positive feedback loops was speculated. During the terminal stages of the disease, additional metyrosine treatment successfully stabilized his physiological and biochemical conditions. Upon the patient's death, pathological autopsy was performed. Immunohistochemical analysis indicated that the tumor appeared to be co-positive with tyrosine hydroxylase (TH) as well as ACTH in most tumor cells in both PCC and liver metastasis. Most cells were clearly positive for somatostatin receptor 2 staining in the membrane compartment. The dense immunostaining of ACTH, TH, dopamine-β-hydroxylase and the large tumor size with positive feedback loops may be correlated with high levels of ACTH and catecholamines in the circulation. CONCLUSIONS We experienced a case of severe ectopic ACTH producing the largest reported recurrent malignant left PCC with liver metastases that presented positive feedback loops in the ACTH/cortisol and catecholamine/cortisol axes. Clinicians should be aware of the paradoxical response of ACTH on metyrapone treatment and possible steroid-induced catecholamine crisis.

Abstract
Air pollution is consistently linked with elevations in cardiovascular disease (CVD) and CVD-related mortality. Particulate matter (PM) is a critical factor in air pollution-associated CVD. PM forms in the air during the combustion of fuels as solid particles and liquid droplets and the sources of airborne PM range from dust and dirt to soot and smoke. The health impacts of PM inhalation are well documented. In the US, where CVD is already the leading cause of death, it is estimated that PM2.5 (PM < 2.5 μm in size) is responsible for nearly 200,000 premature deaths annually. Despite the public health data, definitive mechanisms underlying PM-associated CVD are elusive. However, evidence to-date implicates mechanisms involving oxidative stress, inflammation, metabolic dysfunction and dyslipidemia, contributing to vascular dysfunction and atherosclerosis, along with autonomic dysfunction and hypertension. For the benefit of susceptible individuals and individuals who live in areas where PM levels exceed the National Ambient Air Quality Standard, interventional strategies for mitigating PM-associated CVD are necessary. This review will highlight current state of knowledge with respect to mechanisms for PM-dependent CVD. Based upon these mechanisms, strategies for intervention will be outlined. Citing data from animal models and human subjects, these highlighted strategies include: 1) antioxidants, such as vitamins E and C, carnosine, sulforaphane and resveratrol, to reduce oxidative stress and systemic inflammation; 2) omega-3 fatty acids, to inhibit inflammation and autonomic dysfunction; 3) statins, to decrease cholesterol accumulation and inflammation; 4) melatonin, to regulate the immune-pineal axis and 5) metformin, to address PM-associated metabolic dysfunction. Each of these will be discussed with respect to its potential role in limiting PM-associated CVD.

Abstract
Background:
Exposure to ambient particulate matter (PM) is associated with a number of adverse health outcomes, but potential mechanisms are largely unknown. Metabolomics represents a powerful approach to study global metabolic changes in response to environmental exposures. We therefore conducted this study to investigate changes in serum metabolites in response to the reduction of PM exposure among healthy college students.
Methods:
We conducted a randomized, double-blind crossover trial in 55 healthy college students in Shanghai, China. Real and sham air purifiers were placed in participants’ dormitories in random order for 9 days with a 12-day washout period. Serum metabolites were quantified by using gas chromatography-mass spectrometry and ultrahigh performance liquid chromatography-mass spectrometry. Between-treatment differences in metabolites were examined using orthogonal partial least square-discriminant analysis and mixed-effect models. Secondary outcomes include blood pressure, corticotropin-releasing hormone, adrenocorticotropic hormone, insulin resistance, and biomarkers of oxidative stress and inflammation.
Results:
The average personal exposure to PMs with aerodynamic diameters ≤2.5 μm was 24.3 μg/m
3
during the real purification and 53.1 μg/m
3
during the sham purification. Metabolomics analysis showed that higher exposure to PMs with aerodynamic diameters ≤2.5 μm led to significant increases in cortisol, cortisone, epinephrine, and norepinephrine. Between-treatment differences were also observed for glucose, amino acids, fatty acids, and lipids. We found significantly higher blood pressure, hormones, insulin resistance, and biomarkers of oxidative stress and inflammation among individuals exposed to higher PMs with aerodynamic diameters ≤2.5 μm.
Conclusions:
This study suggests that higher PM may induce metabolic alterations that are consistent with activations of the hypothalamus-pituitary-adrenal and sympathetic-adrenal-medullary axes, adding potential mechanistic insights into the adverse health outcomes associated with PM. Furthermore, our study demonstrated short-term reductions in stress hormone following indoor air purification.

Abstract
The only indication for carbidopa and benserazide is the management of L-3,4-dihydroxyphenylalanine (L-dopa)-induced nausea. Both drugs irreversibly bind to and permanently deactivate pyridoxal 5'-phosphate (PLP), the active form of vitamin B6, and PLP-dependent enzymes. PLP is required for the function of over 300 enzymes and proteins. Virtually every major system in the body is impacted directly or indirectly by PLP. The administration of carbidopa and benserazide potentially induces a nutritional catastrophe. During the first 15 years of prescribing L-dopa, a decreasing Parkinson's disease death rate was observed. Then, in 1976, 1 year after US Food and Drug Administration approved the original L-dopa/carbidopa combination drug, the Parkinson's disease death rate started increasing. This trend has continued to the present, for 38 years and counting. The previous literature documents this increasing death rate, but no hypothesis has been offered concerning this trend. Carbidopa is postulated to contribute to the increasing Parkinson's disease death rate and to the classification of Parkinson's as a progressive neurodegenerative disease. It may contribute to L-dopa tachyphylaxis.

Abstract
During stress, the relationship between the central nervous system and the immune system is essential to maintain homeostasis. The main neuroendocrine system involved in this interaction is the hypothalamic-pituitary-adrenal axis (HPA), which via the synthesis of glucocorticoids will modulate the intensity of the inflammatory response. Anaesthetic agents could be interacting with the HPA axis during surgery. Although etomidate currently remains in the center of the discussions, it seems, at least experimentally, that most hypnotics have the capacity to modulate the synthesis of adrenal steroids. Nevertheless, with the large literature on this subject, etomidate seems to be the most deleterious hypnotic agent on the HPA axis function. Its use should be limited when HPA axis is already altered.

Abstract
Spot baseline urinary monoamine assays have been used in medicine for over 50 years as a screening test for monoamine-secreting tumors, such as pheochromocytoma and carcinoid syndrome. In these disease states, when the result of a spot baseline monoamine assay is above the specific value set by the laboratory, it is an indication to obtain a 24-hour urine sample to make a definitive diagnosis. There are no defined applications where spot baseline urinary monoamine assays can be used to diagnose disease or other states directly. No peer-reviewed published original research exists which demonstrates that these assays are valid in the treatment of individual patients in the clinical setting. Since 2001, urinary monoamine assay sales have been promoted for numerous applications under the "spot baseline urinary neurotransmitter testing marketing model". There is no published peer-reviewed original research that defines the scientific foundation upon which the claims for these assays are made. On the contrary, several articles have been published that discredit various aspects of the model. To fill the void, this manuscript is a comprehensive review of the scientific foundation and claims put forth by laboratories selling urinary monoamine assays under the spot baseline urinary neurotransmitter testing marketing model.

Abstract
Excessive and prolonged stress-induced cortisol changes may contribute to or be a marker of essential hypertension. Cortisol is a central component of the stress response, and it interacts with sympathetic and renal mechanisms contributing to increased blood pressure (BP). Although research in individuals with already established hypertension failed to show consistent abnormalities in adrenocortical output, cortisol responses to psychological stress are greater and more persistent in persons at high risk for hypertension relative to low-risk normotensives. Considering the heterogeneous and multifactorial polygenic nature of hypertension and the fact that cortisol affects several BP related processes, and regulates expression of genes involved in BP, it is possible that this hormone is involved in at least a sub-type of hypertension. Recent studies evaluating cortisol tissue sensitivity, cortisol production and cortisol metabolic rate in hypertension-prone persons support the possibility that cortisol may serve as an intermediate phenotype of hypertension. In this review, we discuss components of the stress responses, factors influencing the adrenocortical response, adrenocortical activity in hypertension, and we propose pathways that mediate effects of stress-induced cortisol on BP.

Abstract
BACKGROUND Abdominal obesity is associated with hyper-responsiveness of the hypothalamic-pituitary-adrenocortical (HPA) axis to stimulatory neuropeptides and to stress. Catecholamines are involved in the regulation of the HPA axis, particularly during stress, via alpha-adrenoceptor modulation. DESIGN In this study, we investigated the effects of pre-treatment with an alpha2-adrenoceptor agonist, clonidine (2 microg/kg over 10 minutes) and antagonist, yohimbine (0.125 mg/kg bolus, followed by 0. 001 mg/kg/minutes per 90 minutes infusion) on the HPA axis, measured by ACTH and cortisol response to combined CRH (human, 100 microg) plus AVP (0.3 IU) administration, and on noradrenalin (NA) and adrenalin (A) blood levels, in a group of obese women with abdominal (A-BFD) or peripheral (P-BFD) body fat distribution and in nonobese controls. RESULTS During the control CRH + AVP test the ACTH but not the cortisol response was higher (P < 0.05) in obese A-BFD women than in controls, with minor and transient variations of NA levels. Neither the control test nor clonidine or yohimbine influenced basal or post CRH + AVP A concentrations. Clonidine pretreatment similarly and significantly decreased NA levels in all women and, compared to the control test, marginally influenced the ACTH response to CRH + AVP. Conversely, during yohimbine infusion NA levels steadily and similarly increased to values more or less double baseline values in all groups. Compared to the control test, however, the ACTH response to the CRH + AVP test performed during yohimbine infusion significantly decreased in the control subjects whereas a tendency to a further increase occurred in the obese groups and, specifically, in the A-BFD group significantly (P < 0.05) more than in the P-BFD group. CONCLUSIONS This study shows that alpha2-adrenoceptor regulation of the HPA axis is different in obese and nonobese women, particularly in stressed conditions. We suggest that the abnormal ACTH response to CRH + AVP challenge with increased noradrenergic tone may represent a specific pathophysiological aspect of the abnormal response to stress or to other specific stimulatory factors in obese women, particularly those with abdominal body fat distribution.

Abstract
OBJECTIVE To summarize the available data on anterior pituitary function in critical illness and to focus on the endocrine effects of dopamine infusion. The analogy with anterior pituitary function in the elderly is highlighted, and the potential importance of these observations for recovery from critical illness is discussed. DATA SOURCES Computerized search of published research and reference list review. STUDY SELECTION Review of 178 citations. Included are seven original studies on the effect of dopamine on pituitary function in adult and pediatric critical illness performed by the authors. DATA EXTRACTION Studies on the endocrinology of illness, chronic stress, aging, and dopamine, or on the clinical importance of endocrine changes. DATA SYNTHESIS The different pituitary axes are important determinants of normal anabolism and immune function. Continuously increased serum cortisol concentrations, insulin resistance, blunted prolactin release, and attenuated pulsatility of growth hormone and luteinizing hormone secretory patterns, as well as multiple anomalies in the thyroid axis, characterize the endocrine profile of prolonged critical illness. Dopamine, a natural catecholamine with hypophysiotropic properties, which has been used for more than two decades as an inotropic and vasoactive drug in intensive care, suppresses the circulating concentrations of all anterior pituitary-dependent hormones, except for cortisol. Available evidence suggests that the major effect of dopamine administration on the endocrine system is unlikely to be beneficial for the threatened metabolic and immunologic homeostasis of the severely ill patient. This pattern of hypopituitarism induced by chronic, severe illness and exogenous dopamine administration is reminiscent of the hormonal profiles obtained in experimental models of chronic stress, suggesting that endogenous dopamine may play a role in the endocrine and metabolic response to critical illness. CONCLUSIONS The dopamine-induced or aggravated pituitary dysfunction in critical illness warrants caution with prolonged infusion of this catecholamine as a so-called supportive agent, particularly in early life. The potential of combined hormonal therapy to improve the metabolic and immune status of the critically ill patient deserves thorough investigation.

Abstract
The hypothalamic hypophysiotrophic neurones are densely innervated by adrenergic and noradrenergic nerve terminals. Activation of alpha 1-adrenoceptors located in the brain stimulates the secretion of ACTH, prolactin and TSH. The effects of the alpha 1-adrenoceptors seem to be exerted on hypothalamic neurones that secrete vasopressin, CRH-41 and TRH. These mechanisms are important in the physiological control of the secretion of ACTH and TSH in humans. alpha 2-Adrenoceptors are not involved in the control of secretion of these hormones under basal conditions in humans. However, alpha 2-adrenoceptors exert an inhibitory effect that acts as a negative feedback mechanism, limiting excessive secretion of these hormones. There is no convincing evidence for the involvement of beta-adrenoceptors in the control of the secretion of these three hormones in humans. Studies on cultured anterior pituitary cells suggested that adrenaline and noradrenaline may influence the secretion of ACTH, prolactin and TSH directly at the level of the pituitary. However, these effects are not demonstrable in humans, and are likely to be due to alterations in the pituitary adrenoceptors during culture. In the case of growth hormone, activation of alpha 2-adrenoceptors located in the brain stimulates secretion of this hormone both by increasing the secretion of GHRH and by inhibiting the secretion of somatostatin. Activation of beta-adrenoceptors inhibits the secretion of growth hormone via an increase in the secretion of somatostatin. The effects of the central alpha 2- and beta-adrenoceptors are important in the physiological control of growth hormone secretion in humans. A considerable amount of evidence implicates brain alpha 1-adrenoceptors in the control of secretion of the gonadotrophins in experimental animals, but, despite intensive study, no convincing evidence has been found in humans of reproductive age.

Abstract
Activation of hypothalamic α(1) -adrenoceptors stimulates the secretion of corticotrophin-releasing factors which in turn stimulate pituitary adrenocorticotrophin (ACTH). This mechanism is important in the physiological control of ACTH secretion. This study assesses the feasibility of using the ACTH response to release of endogenous catecholamines as a means of detecting a hypothalamic noradrenergic lesion in vivo. Intracerebroventricular infusion of the catecholamine neurotoxin, 6-hydroxydopamine, was used to destroy noradrenergic nerve endings in rats, with the purpose of producing a model that could be used to study alterations in ACTH responses that may result from a lesion involving central noradrenergic neurons. 6-Hydroxydopamine (250 μg icv) significantly reduced hypothalamic noradrenaline content, indicating damage to noradrenergic nerve endings, without affecting postsynaptic receptor function, as judged by preservation of the effect of a selective α(1) -adrenergic agonist. Pharmacological release of endogenous catecholamines, effected by combined administration of a catecholamine precursor and an α(2) -adrenergic antagonist, stimulated the secretion of ACTH in control, but not in 6-hydroxydopamine-treated rats. Degeneration of hypothalamic noradrenergic nerve endings is not followed by denervation hypersensitivity, and is therefore accompanied by impairment of the ACTH response to release of endogenous catecholamines.

Abstract
We have investigated neurotransmitter-related markers of the cerebrospinal fluid (CSF) in a carefully screened series of normally aging subjects in standardized conditions in order to find out the influence of age and other confounding factors on CSF measures. The levels of 3-methoxy-4-hydroxyglycol (MHPG) and the activity of acetylcholinesterase (AChE) also increased with age, while homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5 HIAA) and immunoreactivities of somatostatin (SLI), beta-endorphin (BLI) and adrenocorticotropic hormone (ACTH) were unrelated to age. The gender of subjects had no significant effect on the levels of neurotransmitter markers, while seasonal changes, as well as height and weight of the subjects seemed to cause some variations in the levels of HVA, dopamine-beta-hydroxylase (DBH) and ACTH. The study underscores the importance of standardized conditions and matched patient groups in the CSF studies.

Abstract
The role of alpha-adrenoceptors in the mediation of autonomic function, particularly in the control of the cardiovascular system, is widely known. However, alpha-adrenoceptors are also important in the regulation of a variety of metabolic processes that occur in the body either through direct action or by stimulation of the release of other mediators that control metabolic function. Thus, alpha 2-adrenoceptor activation by circulating or neuronally released catecholamines inhibits the release of insulin from pancreatic islet beta-cells and, by inhibiting this response, alpha 2-adrenoceptor antagonists have been shown to have an antihyperglycemic effect. The alpha-adrenoceptor-mediated regulation of the release of pituitary hormones is indirect, with alpha-adrenoceptors being located on peptidergic neurons in the hypothalamus that secrete releasing hormones into the hypophysial portal system to regulate the secretion of hormones from the anterior pituitary gland. Thus, the increase in cortisol secretion from the adrenal glands following a meal is produced, at least in part, by an alpha 1-adrenoceptor-mediated increase in vasopressin and CRF-41 secretion from neurons on the hypothalamus that stimulate the release of adrenocorticotrophic hormone secretion from the pituitary gland, which subsequently stimulates the synthesis and release of cortisol from the adrenal medulla. In addition to metabolic regulation by alpha 1- and alpha 2-adrenoceptors within the endocrine system, alpha-adrenoceptors are also a component of the system that regulates certain aspects of metabolism within autonomic effector cells, such as the control of smooth muscle cell division and growth during periods of continued alpha-adrenoceptor activation as a result of activation of second messenger systems.
