Long-term consequences of anorexia nervosa

Blazej Meczekalski; Agnieszka Podfigurna-Stopa; Krzysztof Katulski

Anorexia nervosa (AN) is a psychiatric disorder that occurs mainly in female adolescents and young women. The obsessive fear of weight gain, critically limited food intake and neuroendocrine aberrations characteristic of AN have both short- and long-term consequences for the reproductive, cardiovascular, gastrointestinal and skeletal systems. Neuroendocrine changes include impairment of gonadotropin releasing-hormone (GnRH) pulsatile secretion and changes in neuropeptide activity at the hypothalamic level, which cause profound hypoestrogenism. AN is related to a decrease in bone mass density, which can lead to osteopenia and osteoporosis and a significant increase in fracture risk in later life. Rates of birth complications and low birth weight may be higher in women with previous AN. The condition is associated with fertility problems, unplanned pregnancies and generally negative attitudes to pregnancy. During pregnancy, women with the condition have higher rates of hyperemesis gravidarum, anaemia and obstetric complications, as well as impaired weight gain and compromised intrauterine foetal growth. It is reported that 80% of AN patients are affected by a cardiac complications such as sinus bradycardia, a prolonged QT interval on electrocardiography, arrythmias, myocardial mass modification and hypotension. A decrease in bone mineral density (BMD) is one of the most important medical consequences of AN. Reduced BMD may subsequently lead to a three- to seven-fold increased risk of spontaneous fractures. Untreated AN is associated with a significant increase in the risk of death. Better detection and sophisticated therapy should prevent the long-term consequences of this disorder. The aims of treatment are not only recovery but also prophylaxis and relief of the long-term effects of this disorder. Further investigations of the long-term disease risk are needed.

IntroductionFunctional hypothalamic amenorrhea (FHA) is one of the most common causes of secondary amenorrhea. There are three types of FHA: weight loss-related, stress-related, and exercise-related amenorrhea. FHA results from the aberrations in pulsatile gonadotropin-releasing hormone (GnRH) secretion, which in turn causes impairment of the gonadotropins (follicle-stimulating hormone and luteinizing hormone). The final consequences are complex hormonal changes manifested by profound hypoestrogenism. Additionally, these patients present mild hypercortisolemia, low serum insulin levels, low insulin-like growth factor 1 (IGF-1) and low total triiodothyronine.AimThe aim of this work is to review the available data concerning the effects of FHA on different aspects of women’s health.ResultsFunctional hypothalamic amenorrhea is related to profound impairment of reproductive functions including anovulation and infertility. Women’s health in this disorder is disturbed in several aspects including the skeletal system, cardiovascular system, and mental problems. Patients manifest a decrease in bone mass density, which is related to an increase in fracture risk. Therefore, osteopenia and osteoporosis are the main long-term complications of FHA. Cardiovascular complications include endothelial dysfunction and abnormal changes in the lipid profile. FHA patients present significantly higher depression and anxiety and also sexual problems compared to healthy subjects.ConclusionsFHA patients should be carefully diagnosed and properly managed to prevent both short- and long-term medical consequences.

Abstract Infertility is a widely disputed problem affecting patients suffering from polycystic ovary syndrome (PCOS). As a serious dysfunction, it frequently occurs in PCOS patients. It is, therefore, important to devote more attention to pregnancy in PCOS sufferers. According to various data, the risk of miscarriage in PCOS women is three times higher than the risk of miscarriage in healthy women. Unfortunately, the risk of most frequent pregnancy pathologies is also higher for PCOS patients, as gestational diabetes (GD), pregnancy-induced hypertension and pre-eclampsia, and small for gestational age (SGA) children. Impaired glucose tolerance and GD in pregnant PCOS patients occur more frequently than in healthy women. A quadruple increase in the risk of pregnancy-induced hypertension linked to arterial wall stiffness has also been observed in PCOS patients. The risk of pre-eclampsia, the most severe of all complications, is also four times higher in those suffering from PCOS. Pre-eclampsia is also more frequent in patients presenting additional risk factors accompanying PCOS, such as obesity or GD. At that point, it should be mentioned that PCOS patients are under 2.5 higher risk of giving birth to SGA children than healthy women. It appears that SGA can be linked to insulin resistance and insulin-dependent growth dysfunction. Therefore, PCOS pregnant women are patients of special obstetrical care.

Abstract Kallmann syndrome (KS) can be characterized as genetic disorder marked by hypogonadotropic hypogonadism and anosmia. Franz Jozef Kallmann was the first who described this disease in 1944. He suggested, that this disease has hereditary background. At present, six genes are regarded as causal genes of KS. These genes can be listed in chronological order: KAL1, FGFR1, FGF8, CHD7, PROKR2 and PROK2. The sensitivity of molecular testing of KS is only about 30%. Diagnosis based on clinical findings is therefore such important. Cardinal features of patients with KS include hypogonadotropic hypogonadism and anosmia or hyposmia. Some non-reproductive, non-olfactory symptoms can also be present, depending on the genetic form of disease. Some patients with KS present midline cranial anomalies (cleft lip, cleft palate and imperfect fusion). Sometimes patients can also suffer from missing teeth (dental agenesis). Optic problems, such as colour blindness or optic atrophy also can occur in KS patients. Very characteristic symptom in KS patients is mirror movements of the upper limbs (imitation synkinesis for contralateral limbs). The type of treatment in women with KS depends on the goal of therapy. After the diagnosis of syndrome, the main goal of the treatment is to induce and maintain secondary sex characteristic (estrogen-progestin therapy). The further goal in some patients can be related to enable fertility (gonadotropin, gonadotropin-releasing hormone therapy).

Abstract Polycystic ovary syndrome (PCOS) affects 5–10% of the population of women. The exact etiology of PCOS remains unclear, but it is believed to result from complex interactions between genetic, behavioral and environmental factors. The spectrum of its symptoms such as hirsutism, skin problems, obesity and finally infertility has a huge negative impact on the individuals’ psychological and interpersonal functioning. PCOS symptoms can lead to significant deterioration in quality of life and be highly stressful negatively affecting psychological well-being and sexuality. Fear symptoms like palpitation, being out of breath and tension might be caused by many somatic diseases. Moreover, detection and continuous thinking about illness can lead to significant negative impact on individual functioning in society. PCOS may be a factor potentially favoring the occurrence of mood disorders and depression. Biological, social and psychological consequences of PCOS among women of reproductive age are opening a new perspective on management of women’s health in these patients.

Eating disorders (EDs) are disturbances that seriously endanger the physical health and often the lives of sufferers and affect their psychosocial functioning. EDs are usually thought of as problems afflicting teenagers. However, the incidence in older women has increased in recent decades. These cases may represent either late-onset disease or, more likely, a continuation of a lifelong disorder. The DSM-5 classification differentiates 4 categories of eating disorder: anorexia nervosa, bulimia nervosa, binge-eating disorders and other specified feeding and eating disorders. The weight loss and malnutrition resulting from EDs have widespread negative consequences for physical, mental and social health. The main risk factors for developing long-term consequences are the degree of weight loss and the chronicity of the illness. Most of the cardiac, neurological, pulmonary, gastric, haematological and dermatological complications of EDs are reversible with weight restoration. EDs are serious illnesses and they should never be neglected or treated only as a manifestation of the fashion for dieting or a womans wish to achieve an imposed standard feminine figure. Additionally, EDs are associated with high risk of morbidity and mortality. The literature concerning EDs in older, postmenopausal women is very limited. The main aim of this paper is to ascertain the epidemiology and prognosis of EDs in older women, and to review their diagnosis and management.

Health in older women athletes.

Blazej Meczekalski; Krzysztof Katulski; Adam Czyzyk; Agnieszka Podfigurna-Stopa

Physical activity has been identified as a protective factor against a wide spectrum of diseases, but little is known about the link between older womens health and their professional involvement in sport in the past. The aim of this narrative review is to characterize and summarize the available data concerning the influence of physical activity on morbidity and mortality in former female athletes. Concerning bone health, it seems that physical activity in the past can be protective against osteoporosis in postmenopausal women, but these data come from observational studies only. Also the cardiovascular system appears to benefit in older women from regular sport in the past. This refers mainly to better heart efficiency, and improved endothelial function and metabolic profile. The incidence of different types of neoplasms, especially breast cancer, is also decreased in former athletes. Professional sport, on the other hand, acts negatively on the pelvic floor and is a risk factor for urinary incontinence. The overall effect on mortality is difficult to assess, because of many parameters, such as the sports intensity, variety of the sport and exposure to extreme danger in some disciplines. Also, caution should be kept in interpretation of the data because of the shortage of well-designed studies.

Abstract Thecoma is a rare ovarian tumor, presenting usually in postmenopausal women as unilateral, benign, solid lesion. About 15% of affected patients develop endometrial hyperplasia (EH) and 20% are diagnosed with endometrial cancer. In this case report, we present 60-year-old women admitted because of recurrent spotting of 5 years duration, which started 1 year after menopause. In history, the patient underwent three times curettage procedures and once (1 year before admission) had estradiol levels typical for reproductive-age women. At admission, we found elevated serum levels of estradiol (222.5 pg/ml) and a small mass in the right ovary. The markers of germ cell tumors were negative. After the initial diagnosis, the patient was qualified for total abdominal hysterectomy with bilateral salpingo-oophorectomy. The histopathological examination and immunohistochemical staining confirmed the thecoma diagnosis. In follow-up examination after 8 weeks, we found decreased serum estradiol levels and relief of the symptoms. In conclusion, we want to underline that in cases of EH, especially in patients with a history of recurrences, the special attention should be paid for differential diagnosis. In such cases, the estrogen-secreting tumors should be excluded.

Abstract Objective: To evaluate the influence of short-term estriol administration (10 d) on the hypothalamus-pituitary function and gonadotropins secretion in patients affected by functional hypothalamic amenorrhea (FHA). Study design: Controlled clinical study on patients with FHA (n = 12) in a clinical research environment. Intervention(s): Hormonal determinations and gonadotropin (luteinizing hormone [LH] and FSH) response to a gonadotropin-releasing hormone (GnRH) bolus (10 μg) at baseline condition and after 10 d of therapy with 2 mg/d of estriol per os. Main outcome measure(s): Measurements of plasma LH, FSH, prolactin, estradiol, androstenedione, 17α-hydroxyprogesterone, insulin, cortisol, thyroid-stimulating hormone, free triiodothyronine, and free thyroxine. Result(s): After treatment, the FHA patients showed a statistically significant increase of both LH and FSH plasma levels and the significant increase of their responses to the GnRH bolus. Conclusion(s): Estriol short-term therapy modulates within 10 d of administration the neuroendocrine control of the hypothalamus-pituitary unit and induces the recovery of both gonadotropins synthesis and secretion in hypogonadotropic patients with FHA.

Abstract Objective: A case report of a patient diagnosed with Camurati-Engelmann Disease (CED) in association with the functional hypothalamic amenorrhea disturbances. CED is a very rare genetically determined disorder classified as a type of bone dysplasia. Design: Case report. Setting: Department of Gynecological Endocrinology, 3rd grade Medical University Hospital. Patient: Twenty-one years old female patient with CED admitted to the hospital because of primary amenorrhea. Her history revealed skeletal deformities and hearing impairment. Methods: Clinical examination, ultrasound, laboratory evaluations (including serum gonadotropins (FSH, LH) at basal state and after stimulation with gonadotropin-releasing hormone, serum basal estradiol) radiological studies (X-ray of the head, the lumbar spine and lower extremities; a computed tomography of the head), G-banding karyotype, polymerase chain reaction and DNA sequencing. Hormonal serum evaluations were made using an enzyme-linked immunosorbent assay. The exon 4 of the transforming growth factor beta 1 gene was amplified by a polymerase chain reaction and the product was directly sequenced. Results: The hormonal analysis was characteristic for the hypogonadotropic hypogonadism. Radiological and molecular analyses confirmed CED diagnosis. Conclusions: The hypothalamic amenorrhea in a patient with CED may be explained as a consequence of fat hypotrophy and very low body mass index. Therefore, impairment within hypothalamic-pituitary axis in patients with CED should be treated with special attention.
