The c.1460C>T Polymorphism of MAO-A Is Associated with the Risk of Depression in Postmenopausal Women

Objective. The aim of the study was an evaluation of possible relationships between polymorphisms of serotoninergic system genes and the risk of depression in postmenopausal women. Methods. We studied 332 women admitted to our department because of climacteric symptoms. The study group included 113 women with a diagnosis of depressive disorder according to the Hamilton rating scale for depression; the controls consisted of 219 women without depression. Serum 17β-estradiol concentrations were evaluated using radioimmunoassay, while polymorphisms in serotoninergic system genes: serotonin receptors 2A (HTR2A), 1B (HTR1B), and 2C (HTR2C); tryptophan hydroxylase 1 (TPH1) and 2 (TPH2), and monoamine oxidase A (MAO-A) were evaluated using polymerase chain reaction-restriction. Results. We found that the 1460T allele of MAO-A c.1460C>T (SNP 1137070) appeared with a significantly higher frequency in depressed female patients than in the control group (P = 0.011) and the combined c.1460CT + TT genotypes were associated with a higher risk of depression (P = 0.0198). Patients with the 1460TT genotype had a significantly higher 17β-estradiol concentration than patients with the 1460CT genotype (P = 0.0065) and 1460CC genotype (P = 0.0018). Conclusions. We concluded that depression in postmenopausal women is closely related to the genetic contribution of MAO-A

Genetic aspects of premature ovarian failure

Wśród przyczyn zespołu przedwczesnego wygasania czynności jajników (POF) wymienia się dwie grupy czynników: zaburzenia prowadzące do zmniejszenia liczby pęcherzyków jajnikowych oraz stany prowadzące do przyśpieszonej atrezji pęcherzyków. W pierwszej grupie główną rolę odgrywają czynniki genetyczne, podczas gdy w drugiej takie przyczyny jak defekty enzymatyczne, zaburzenia autoimmunologiczne, czynniki jatrogenne, toksyny środowiskowe i zakażenia. W 1986 roku opisano rodzinne występowanie POF spowodowane delecją DNA w obrębie ramienia długiego chromosomu X (Xq). Kolejnymi chromosomami, które są istotne z punktu widzenia prawidłowej funkcji jajnika są: chromosom 21 (zawierający gen AIRE), chromosom 11 (gen podjednostki β FSH, gen ATM), chromosom 3 (gen odpowiedzialny za występowanie zespołu BEPS) oraz chromosom 2 (geny dla receptorów dla FSH i LH). W artykule omówiono rolę poszczególnych genów oraz wyniki odpowiednich badań epidemiologicznych.Among the causes of premature ovarian failure (POF) two groups of factors are reported: factors which lead to decrease of follicular number and factors which stimulate follicular atresia. In the first group genetic factors are the most important whereas in the second: enzymatic autoimmunological, iatrogenic, toxins and infections are reported. In 1986 familiar POF on the background of long arm of chromosome X deletion was reported. Other chromosomes which are important for normal ovarian function are: chromosome 21 (AIRE gene), chromosome 11 (gene of β FSH, ATM gene), chromosome 3 (gene responsible for BEPS syndrome) and chromosome 2 (genes of FSH and LH receptors). In this review the role of these genes and results of several epidemiological studies are reported

Depression in children and adolescents

In recent years, the situation of child and adolescent psychiatry in Poland has dramatically deteriorated. 24-hour psychiatric wards dedicated to minors are overcrowded and it is almost exclusively patients who are a direct threat to their own health or life that are hospitalised. About 20% of children and adolescents have symptoms of various mental disorders, of which 10% (about 400,000) require specialist care. Depression is one of the most common health problems among children and adolescents and its prevalence increases with age and puberty. Depression can be chronic, with constant severity, or recurrent, when symptoms return in the form of mild, moderate or severe episodes. The mood disorders occurring in the developmental period carry many negative consequences in the emotional, social and educational functioning of the patient. They increase the risk of self-destructive behaviours, suicide, abuse of psychoactive substances, as well as later difficulties in many areas of life during adulthood

Aromatase inhibitors in the treatment of endometriosis

Endometriosis is a chronic inflammatory condition in which foci of endometrial tissue grow outside of the uterine cavity. Endometriosis was estimated to affect 176 million women of childbearing potential all over the world in 2010. The presence of extrauterine endometrial tissue is associated with pain and infertility. Typical symptoms of endometriosis include dysmenorrhoea, dyspareunia, heavy menstrual periods (menorrhagia), pelvic pain that is not related to menstrual cycles, dysuria, and chronic fatigue. Medical treatments for endometriosis include combined oral contraceptive pills, danazol, gestrinone, medroxyprogesterone acetate, and gonadotropin-releasing hormone agonists (aGnRHs). A new class of medications called aromatase inhibitors has been identified in recent years as potential therapeutic agents for endometriosis. This article provides general information about aromatase inhibitors, their use in gynaecology, and their adverse effects. In particular, the paper discusses the use of aromatase inhibitors in the treatment of endometriosis in postmenopausal women. Unlike oral contraceptives, gestagens, aGnRHs, and danazol, which suppress ovarian oestrogen synthesis, aromatase inhibitors inhibit mainly extra-ovarian synthesis of oestrogens. Therefore, the use of aromatase inhibitors seems to be particularly relevant in older patients, as most of the body’s oestrogen is produced outside the ovaries after menopause. The paper discusses also the use of aromatase inhibitors in the treatment of pain associated with endometriosis and infertility caused by endometriosis

Anorexia Nervosa—What Has Changed in the State of Knowledge about Nutritional Rehabilitation for Patients over the Past 10 Years? A Review of Literature

Anorexia nervosa (AN) is a psycho-metabolic disorder with a high risk of somatic complications such as refeeding syndrome (RFS) and carries the highest mortality rate of all psychiatric illnesses. To date, the consensus on the care for patients with AN has been based on recommendations for a combination of alimentation and psychotherapy. It is important to establish an initial caloric intake that will provide weight gain and minimize the risk of complications in the treatment of undernourished patients. Research over the past few years suggests that current treatment recommendations may be too stringent and should be updated. The aim of this paper is to systematize the current reports on nutritional rehabilitation in AN, to present the results of studies on the safe supplementation of patients and its potential impact on improving prognosis and the healing process. This review of literature, from 2011–2021, describes the changing trend in the nutritional protocols used and the research on their efficacy, safety, and long-term effects. In addition, it presents previous reports on the potential benefits of introducing vitamin, pro-and prebiotic and fatty acid supplementation

ProBDNF as an Indicator of Improvement among Women with Depressive Episodes

Depression is a chronic psychiatric disorder with a heavy socioeconomic burden. Studies on biomarkers are needed to comprehend the pathophysiology of depression and to improve treatment outcomes. Research points to the importance of imbalance between mature brain-derived neurotrophic factor (BDNF) and its precursor, pro–brain–derived neurotrophic factor (proBDNF), in the pathophysiology of mood disorders and the potential neurodegenerative role of calcium-binding protein B (S100B). Our objective was to compare BDNF, proBDNF, and S100B serum levels before and after the treatment of acute depressive episodes and to assess their correlation with the severity of symptoms and history of stress. We also aimed to investigate the differences in BDNF, proBDNF, and S100B levels between depression in the course of bipolar disorder (BD) and major depressive disorder (MDD). We recruited 31 female patients diagnosed with BD or MDD who were hospitalized due to current depressive episodes. The patients had their serum BDNF, proBDNF, and S100B levels evaluated using the ELISA method upon admission and after the symptoms improved, at discharge. We found that proBDNF levels decreased significantly with the treatment (p = 0.0478), while BDNF and S100B levels were not altered significantly. No differences in biochemical parameters between MDD and BD subjects were observed. Consequently, we concluded that a decrease in serum proBDNF levels could be considered a biomarker of recovery from depressive episodes

Denosumab – a new medication in the treatment of postmenopausal osteoporosis

Osteoporosis is a chronic, systemic skeletal disorder characterised by decreased bone density. It leads to an increased risk of bone fractures – one of the major causes of disability in modern societies. Bisphosphonates are the most commonly used medications in the treatment of postmenopausal osteoporosis. Denosumab, a new approach to fracture prevention, is a fully human monoclonal antibody that targets nuclear factor-B ligand (RANKL), an important cytokine regulating formation and function of osteoclasts. Generally, denosumab is not used as initial therapy; however, in some cases it should be considered. It concerns patients at high risk of fracture, such as older patients who have difficulty with the dosing requirements of oral bisphosphonates or who have markedly impaired renal function. Denosumab can be also considered in patients who present intolerance or unresponsiveness to other therapies. Clinical studies have shown that denosumab is highly effective in increasing bone mineral density (BMD) in postmenopausal women regardless of the site analysed, as well as reducing the risk of bone fractures. The risk of developing antiresorptive, agent-induced osteonecrosis of the jaw related to denosumab therapy is low
