Zhilei Zhao, Seiichiro Jinde, Chihiro Kakiuchi, Kiyoto Kasai
Several recent gene expression studies on schizophrenia, including one using monozygotic twins discordant for the disease, have reported the upregulation of adrenomedullin (ADM), which was initially identified as a vasodilator hormone. It has been hypothesized that upregulation of ADM may be a susceptibility factor for schizophrenia, although the exact role of ADM in the central nervous system remains unclear. In this study, we used a microarray analysis to investigate the changes in global gene expression induced by the administration of exogenous ADM in SK-N-SH cells, which allowed us to evaluate the effects of elevated ADM on the central nervous system...

OBJECTIVES: An herbal preparation called peony-glycyrrhiza decoction (PGD) may have the potential in reducing antipsychotic-related hyperprolactinemia (hyperPRL). This double-blind, randomized placebo-controlled study aimed to reevaluate the efficacy of PGD against antipsychotic-related hyperPRL. METHODS: Ninety-nine schizophrenic women who were under antipsychotic therapy and had symptomatic hyperPRL were randomly assigned to additional treatment with placebo (n = 50) or PGD (n = 49, 45 g/d) for 16 weeks...

Historically endocrinologists and psychiatrists are aware that disturbances in thyroid disease in beginning or even in clinically intensified states of thyrotoxicosis or hypothyroidism exhibit pathological mental manifestations, masking or potentiating the underlying disease. Immune system disorders cause thyroid organ-specific autoimmune process. This autoimmune thyroid disease binds with a number of disorders in both endocrine or non-endocrine organs. This appears in vascular, neurological, skin, connective tissue, gastrointestinal tract and mental pathology...

Social interaction and communication are complex behavioral paradigms involving many components. Many different neurotransmitters, hormones, sensory inputs, and brain regions are involved in the act of social engagement and verbal or nonverbal communication. Autism Spectrum Disorder (ASD) and schizophrenia are two neurodevelopmental disorders that have social and language deficits as hallmark symptoms, but show very different etiologies. The output of social dysfunction is common to both ASD and schizophrenia, but this likely arises from very different pathophysiological means...

BACKGROUND: Gender differences in schizophrenia have been recognized for a long time and it has been widely accepted that sex steroid hormones, especially estradiol, are strongly attributed to this fact. Two hypotheses regarding estradiol action in psychoses gained special research attention - the estrogen protection hypothesis and hypoestrogenism hypothesis. A growing number of studies have shown benefits in augmenting antipsychotic treatment with estrogens or selective estrogen receptor modulators (SERM)...

There is a growing realisation that the gut-brain axis and its regulation by the microbiota may play a key role in the biological and physiological basis of neurodevelopmental, age-related and neurodegenerative disorders. The routes of communication between the microbiota and brain are being unravelled and include the vagus nerve, gut hormone signalling, the immune system, tryptophan metabolism or by way of microbial metabolites such as short chain fatty acids. The importance of early life gut microbiota in shaping future health outcomes is also emerging...

Recently, extensive efforts have been made to understand the rate of energy expenditure and the weight gain associated with atypical antipsychotic treatment, including identification of markers of obesity risk. In recent years, leptin, an adipocyte hormone, has gained significant interest in psychiatric disorders. S100B has been considered as a surrogate marker for astrocyte-specific damage in neurologic disorders. Also, S100B has been detected in adipose with concentration as high as nervous tissue as a second release source...

Sex differences appear to be an important factor in schizophrenia. Women with schizophrenia tend to exhibit less disease impairment than men, typically presenting with a later age-at-onset, lower overall incidence and less severe symptoms. These observations underpin the estrogen hypothesis of schizophrenia, which postulates a protective role of estrogen against the development and severity of the disorder. While there has been significant attention placed on the impact of estrogens in schizophrenia, less consideration has been afforded to the role of progesterone, the other main female gonadal hormone...

OBJECTIVE: Metabolic adverse effects of atypical antipsychotics (AAP) contribute significantly to increased risk of cardiovascular morbidity and mortality in patients suffering from schizophrenia. Extensive preclinical research has addressed this issue over the past years, though mechanisms underlying these adverse effects of AAP are still not understood completely. Recently, attention is drawn towards the role of adipose tissue metabolism and neurohormonal regulations. METHODS: The aim of this study was to evaluate the time-dependent effects of olanzapine depot administration at clinically relevant dosing on the regulation of energy homeostasis, glucose and lipid metabolism, gastrointestinal and adipose tissue-derived hormones involved in energy balance regulations in female Sprague-Dawley rats...

Low bone mineral density (BMD) and osteoporosis are common in patients with schizophrenia and detrimental to illness prognosis and life quality. Although the pathogenesis is not fully clear, series of studies have revealed factors related to low BMD such as life style, psychotic symptoms, medication use and the activity of bone absorption markers. It has been known that antipsychotic-induced hyperprolactinemia plays a critical role on decreased BMD. However, it remains uncertain whether the risk factors differ between men and women...

IMPORTANCE: A substantial proportion of women with schizophrenia experience debilitating treatment-refractory symptoms. The efficacy of estrogen in modulating brain function in schizophrenia has to be balanced against excess exposure of peripheral tissue. Raloxifene hydrochloride is a selective estrogen receptor modulator (mixed estrogen agonist/antagonist) with potential psychoprotective effects and fewer estrogenic adverse effects. OBJECTIVE: To determine whether adjunctive raloxifene therapy reduces illness severity in women with refractory schizophrenia...

BACKGROUND: Increasing evidence shows that schizophrenia patients with long-term exposure to antipsychotic medications have decreased bone mass, which suggests that they are at a high risk of osteoporosis. However, the mechanism underlying this remains unclear. In this study, we selected two bone turnover markers to explore whether atypical antipsychotics can affect bone metabolism and identified possible influencing factors. METHODS: A total of 116 schizophrenia patients (18-40years old) participated in the study...

Astroglial cells have been considered to have passive brain function by helping to maintain neurons. However, recent studies have revealed that the dysfunction of such passive functions may be associated with various neuropathological diseases, such as schizophrenia, Alzheimer's disease, amyotrophic lateral sclerosis and major depression. Corticosterone (CORT), which is often referred to as the stress hormone, is a well-known regulator of peripheral immune responses and also shows anti-inflammatory properties in the brain...

BACKGROUND: Prenatal gonadal hormones may play a major role in pathogenesis of schizophrenia. It has been reported that second to fourth digit ratio (2D:4D) was influenced by the levels of exposure to prenatal testosterone and estrogen. So, 2D:4D may help to predict the disease susceptibility to schizophrenia. AIMS: The aim of this study was to investigate the relationship between the digit ratio (2D:4D) and schizophrenia in Chinese population. METHODS: We recruited 178 schizophrenics (males: 76; females: 102) and 365 controls (males: 218; females: 147) in this study...

Sex differences in neurological disease exist in incidence, severity, progression, and symptoms and may ultimately influence treatment. Cognitive disturbances are frequent in neuropsychiatric disease with men showing greater cognitive impairment in schizophrenia, but women showing more severe dementia and cognitive decline with Alzheimer's disease. Although there are no overall differences in intelligence between the sexes, men, and women demonstrate slight but consistent differences in a number of cognitive domains...

Schizophrenia has a clear sexual dimorphism in age of onset and progression. The underlying mechanisms of this dimorphism are not known, but may be found in the interactions of sex hormones with the tryptophan catabolising kynurenine pathway. Schizophrenia is associated with general inflammation and disruption of glutamatergic and dopaminergic signalling. Metabolites of the kynurenine pathway have been shown to be immunomodulatory and have effects on glutamatergic and dopaminergic signalling. This review discusses the currently available literature on sex hormones and their effect on the kynurenine pathway in the context of the glutamatergic, dopaminergic and immunological features of schizophrenia...
