The relationship between polycystic ovary syndrome and antiepileptic drugs: a review of the evidence

Curcumin protects against lamotrigine-induced chronic ovarian and uterine toxicity in rats by regulating PPAR-γ and ROS production

Lamotrigine (LTG) is an antiepileptic drug with possible adverse effects on the female reproductive system. Curcumin was declared to improve ovarian performance. Therefore, this study aimed to clarify ovulatory dysfunction (OD) associated with LTG and the role of curcumin in ameliorating this dysfunction. Adult female Wister albino rats were assigned into four groups: negative control (received saline), positive control (received curcumin only), LTG, and LTG with curcumin groups. Drugs were administered for 90 days. The hormonal profile, including testosterone, estrogen, progesterone, luteinizing hormone, and follicle-stimulating hormone, in addition to the lipid profile and glycemic analysis, were tested. Oxidative stress biomarkers analysis in the ovaries and uterus and peroxisome proliferator-activated receptor-γ (PPAR-γ) gene expression were also included. Histopathological examination of ovarian and uterine tissues and immunohistochemical studies were also performed. Curcumin could improve the OD related to chronic LTG intake. That was proved by the normalization of the hormonal profile, glycemic control, lipidemic status, oxidative stress markers, and PPAR-γ gene expression. The histopathological and immunohistochemical examination of ovarian and uterine tissues revealed an improvement after curcumin administration. The results describe an obvious deterioration in ovarian performance with LTG through the effect on lipidemic status, PPAR-γ gene, and creating an oxidative stress condition in the ovaries of chronic users, with a prominent improvement with curcumin addition to the treatment protocol.

Serum testosterone levels in bipolar and unipolar depressed female patients and the role of medication status

Objective: to compare testosterone levels between female depressed patients and female bipolar patients.Methods: Sixty-one female patients with major depressive disorder (MDD) (n = 23) or bipolar disorder (BD) (n = 38) between 18 and 45 years old were included in the study. Participants were evaluated during a depressive or manic episode with the Hamilton depression rating scale (HDRS) or Young mania rating scale (YMRS), respectively. No patients in the MDD group were taken valproate while in the BD group 14 (36.84%) were taken valproate. Total testosterone (TT) and free testosterone (FT) levels were quantified during the early follicular phase of the cycle, with radioimmunoassay or solid phase enzyme-linked immunoassay. Data were collected from May 2016 to February 2017.Results: Mean TT serum levels were significantly higher in BD patients in comparison to MDD patients. Although age and diagnosis were related to TT levels, however when we added valproate use in the analysis, only the relation between TT and valproate use remained significant.Conclusions: In this sample, TT levels were related to valproate use in patients with BD. More studies regarding the role of testosterone in affective symptoms should be conducted to clarify the relation between testosterone, affective disorders, and medication.KeypointsWe observed that testosterone levels were significant higher in bipolar women compared to women with MDD.The use of valproate could be associated with the testosterone levels in female patients with BD.Evaluation of women suffering BD should include a testosterone levels determination, particularly when they are taking valproate.

Infertility and mental health

The World Health Organization (WHO) has indicated that 8–12% of couples worldwide experience infertility, and in recent years the number seeking treatment has dramatically increased. The diagnosis and therapy put a heavy psychological and physical burden on most patients, female and male. The incidence of depression in couples presenting for infertility treatment is significantly higher than in comparable fertile couples. Anxiety is significantly higher in infertile couples than in the general population. Professionals have become aware of the importance of providing educational interventions to address patients' fears and concerns, and to better prepare patients for the demands of treatment. Health professionals should follow a patient-centred approach to provide for the specific needs of the couple. Women in general have a positive attitude to seeking psychological help in the form of cognitive-behavioural therapy, couples counselling and infertility counselling.

Bipolar affective disorder and its impact on various aspects of marital relationship

Bipolar disorder (BD) is a severe mental disorder, which not only has negative consequences on the life of the patient, but also affects the immediate family members. As it often starts early in life, patients who get married often suffer from many negative consequences in their marital life due to the illness. This review focuses on studies which have evaluated marital rates, rate of marital failure, divorce, infertility, and procreation among patients with BD. In addition, this review evaluates the existing literature pertaining to marital adjustment, marital satisfaction, sexual dysfunction, and sexual satisfaction among patients with BD and their partners/spouses. Data suggest that very high proportion of patients with BD get married and marital rates are higher for patients with BD, when compared with those suffering from schizophrenia. In terms of divorce rates, studies suggest that patients with BD have higher rates of divorce. In terms of fertility rates, studies suggest that compared to those without the illness, the fertility rates among patients with BD are lower. In terms of marital adjustment, results are mixed with some studies suggesting poorer marital adjustment among patients and their spouses too. In terms of sexual dysfunction, studies suggest the presence of sexual dysfunction among one-third to half of the patients receiving lithium. To conclude, this review suggests that patients with BD experience multiple negative marital and sexual consequences.

Second generation anti-epileptic drugs adversely affect reproductive functions in young non-epileptic female rats

Reproductive endocrine disturbances are a major health concern in women with epilepsy due to their long term use of antiepileptic drugs (AEDs). Second generation AEDs such as topiramate (TPM) and gabapentin are frequently used for the treatment of epilepsy as well as migraine, bipolar disorder etc. Despite the widespread clinical complications, however the definitive mechanism(s) mediating the side effects of TPM and gabapentin remain obscure. The present study was aimed to evaluate the long term effects of TPM and gabapentin on reproductive functions in young female Wistar rats. Estrous cyclicity, ovarian histology as well as estradiol, LH, leptin and insulin hormones level were studied to elucidate the long-term effect of these AEDs monotherapy on reproductive functions in non-epileptic animals. Further to explore the effects on gonadotropin releasing hormone (GnRH) neuroendocrine plasticity, the expression of GnRH, gamma-amino butyric acid (GABA), glutamic acid decarboxylase (GAD), glial fibrilliary acidic protein (GFAP) and polysialylated form of neural cell adhesion molecule (PSA-NCAM) was studied in median eminence (ME) region of these animals by immunohistochemistry, Western blot hybridization and RT-PCR. Our results demonstrate that TPM and gabapentin treatment for 8 weeks cause reproductive dysfunction as ascertained by disturbed hormonal levels and estrous cyclicity as well as alterations in GABAergic system and GnRH neuronal-glial plasticity. Our findings suggest that treatment with TPM and gabapentin disrupts the complete hypothalamo-hypophyseal-gonadal axis (HPG) through GnRH pulse generator in hypothalamus.

Evaluation of reproductive function in women treated for bipolar disorder compared to healthy controls

OBJECTIVES

The purpose of the present study was to investigate the reproductive function of women with bipolar disorder (BD) compared to healthy controls.

METHODS

Women diagnosed with BD and healthy controls with no psychiatric history, aged 18-45 years, were recruited from a university clinic and surrounding community. Participants completed a baseline reproductive health questionnaire, serum hormone assessment, and ovulation tracking for three consecutive cycles using urine luteinizing hormone (LH)-detecting strips with a confirmatory luteal-phase serum progesterone.

RESULTS

Women with BD (n = 103) did not differ from controls (n = 36) in demographics, rates of menstrual abnormalities (MAs), or number of ovulation-positive cycles. Of the women with BD, 17% reported a current MA and 39% reported a past MA. Dehydroepiandrosterone sulfate and 17-hydroxyprogesterone levels were higher in controls (p = 0.052 and 0.004, respectively), but there were no other differences in biochemical levels. Medication type, dose, or duration was not associated with MA or biochemical markers, although those currently taking an atypical antipsychotic agent indicated a greater rate of current or past MA (80% versus 55%, p = 0.013). In women with BD, 22% reported a period of amenorrhea associated with exercising or stress, versus 8% of controls (p = 0.064). Self-reported rates of bulimia and anorexia nervosa were 10% and 5%, respectively.

CONCLUSIONS

Rates of MA and biochemical levels did not significantly differ between women with BD and controls. Current atypical antipsychotic agent use was associated with a higher rate of current or past MA and should be further investigated. The incidence of stress-induced amenorrhea should be further investigated in this population, as should the comorbid incidence of eating disorders.

Neuroendocrine considerations in the treatment of men and women with epilepsy

Complex, multidirectional interactions between hormones, seizures, and the medications used to control them can present a challenge for clinicians treating patients with epilepsy. Many hormones act as neurosteroids, modulating brain excitability via direct binding sites. Thus, changes in endogenous or exogenous hormone levels can affect the occurrence of seizures directly as well as indirectly through pharmacokinetic effects that alter the concentrations of antiepileptic drugs. The underlying structural and physiological brain abnormalities of epilepsy and the metabolic activity of antiepileptic drugs can adversely affect hypothalamic and gonadal functioning. Knowledge of these complex interactions has increased and can now be incorporated in meaningful treatment approaches for men and women with epilepsy.

Undiagnosis: an important new role for psychiatry

OBJECTIVE

This paper discusses an activity, hitherto inadequately identified, which is an increasingly important part of contemporary practice.

CONCLUSION

Iatrogenesis presents today in new guises but can be satisfying and productive to address.

Antiepileptic drugs, sex hormones, and PCOS

Reproductive endocrine dysfunction in women with epilepsy is an important issue, and in recent years there is growing evidence to support the effect on sex hormones of both epilepsy per se and various antiepileptic drugs (AEDs). Focal epileptic discharges from the temporal lobe may have a direct influence on the function of the hypothalamic-pituitary axis, thereby altering the release of sex steroid hormones. The role of laterality and severity of epilepsy is still conflicting. The use of the liver enzyme-inducing AEDs--such as phenobarbital, phenytoin, and carbamazepine--can increase serum sex hormone-binding globulin concentrations, leading to diminished bioactivity of testosterone (T) and estradiol. Valproic acid, an enzyme inhibitor, has been associated with the occurrence of reproductive endocrine disorders characterized by high serum T, free androgen index, androstenedione, dehydroepiandrosterone sulfate concentrations, and with polycystic changes in ovaries and menstrual disorders. A better understanding of the effects of AEDs on sex hormones is key to selecting the appropriate AEDs and is crucial for reproductive health in female patients.

Incidence of polycystic ovaries and androgen serum levels in women with borderline personality disorder

Obesity, increased visceral fat and disturbed glucose metabolism have been found in borderline personality disorder (BPD) patients. These conditions are often associated with disturbed androgen metabolism. Elevated androgens in women are related to polycystic ovaries (PCO) and might have an impact on psychopathology. Thus, higher prevalence of PCO and elevated androgen levels are suspected in BPD. In the study, we examined 31 BPD patients and 30 healthy controls ultrasonographically for PCO and measured their serum levels of androgens and interacting hormones. Furthermore, influence on psychopathology of free testosterone (FT) serum level was assessed. PCO was significantly more prevalent in BPD patients (30.4%) compared to healthy controls (6.9%). Testosterone, FT, androstenedione (A), and 17alpha-hydroxyprogesterone (17-OHP) were significantly elevated in the BPD group independently of BMI. FT serum level significantly correlated with depressive symptoms. In summary, our data suggest a disturbed androgen metabolism in BPD patients.

Polycystic ovaries and polycystic ovary syndrome in epilepsy: evidence for neurogonadal disease

Polycystic ovary syndrome (PCOS) is a mysterious reproductive disorder that results in subfertility. The underlying causes are not known, and even the definition is a moving target. Women with epilepsy have features of PCOS at a higher than expected rate, and polycystic ovaries (PCO) also are present at high rates in this population. Valproate is associated with weight gain and increased androgen levels, two features of PCOS. This review proposes that epilepsy, with its known adverse effects on luteinizing hormone pulsatility, could be a cause of PCOS and that valproate could be an imitator, if not also a cause of the syndrome.

Controversies concerning the diagnosis and treatment of bipolar disorder in children

This commentary grows out of an interdisciplinary workshop focused on controversies surrounding the diagnosis and treatment of bipolar disorder (BP) in children. Although debate about the occurrence and frequency of BP in children is more than 50 years old, it increased in the mid 1990s when researchers adapted the DSM account of bipolar symptoms to diagnose children. We offer a brief history of the debate from the mid 90s through the present, ending with current efforts to distinguish between a small number of children whose behaviors closely fit DSM criteria for BP, and a significantly larger number of children who have been receiving a BP diagnosis but whose behaviors do not closely fit those criteria. We agree with one emerging approach, which gives part or all of that larger number of children a new diagnosis called Severe Mood Dysregulation or Temper Dysregulation Disorder with Dysphoria.Three major concerns arose about interpreting the DSM criteria more loosely in children than in adults. If clinicians offer a treatment for disorder A, but the patient has disorder B, treatment may be compromised. Because DSM's diagnostic labels are meant to facilitate research, when they are applied inconsistently, such research is compromised. And because BP has a strong genetic component, the label can distract attention from the family or social context.Once a BP diagnosis is made, concerns remain regarding the primary, pharmacological mode of treatment: data supporting the efficacy of the often complex regimens are weak and side effects can be significant. However, more than is widely appreciated, data do support the efficacy of the psychosocial treatments that should accompany pharmacotherapy. Physicians, educators, and families should adopt a multimodal approach, which focuses as much on the child's context as on her body. If physicians are to fulfill their ethical obligation to facilitate truly informed consent, they must be forthcoming with families about the relevant uncertainties and complexities.

Epilepsy, sex hormones and antiepileptic drugs in female patients

Women with epilepsy have a higher incidence of reproductive endocrine disorders than the general female population. These alterations include polycystic ovary syndrome, hyperandrogenemia, infertility, hypothalamic amenorrhea and hyperprolactinemia. Reproductive dysfunction is attributed both to epilepsy itself and to antiepileptic drugs (AEDs). Focal epileptic discharges from the temporal lobe may have a direct influence on the function of the hypothalamic-pituitary axis, thus altering the release of sex steroid hormones, including the production of luteinizing hormone, follicle-stimulating hormone, gonadotropin-releasing hormone and prolactin. AEDs may modulate hormone release from the hypothalamic-pituitary-gonadal axis and they may alter the metabolism of sex hormones and their binding proteins. Hepatic enzyme-inducing AEDs, such as carbamazepine and phenytoin, may be most clearly linked to altered metabolism of sex steroid hormones, but valproic acid, an enzyme inhibitor, has also been associated with a frequent occurrence of polycystic ovary syndrome and hyperandrogenism in women with epilepsy. Therefore, treatment of epilepsy and selection of AEDs are important for reproductive health in female patients. The aim of the present review is to critically evaluate the recently published data concerning the interactions between sex hormones, epilepsy and AEDs.

Divalproex extended-release in adolescent migraine prophylaxis: results of a randomized, double-blind, placebo-controlled study

OBJECTIVE

To evaluate the efficacy, tolerability, and safety of 3 different doses of divalproex sodium extended-release vs placebo in the prophylaxis of migraine headaches in adolescents.

BACKGROUND

Divalproex sodium has been approved for migraine prophylaxis in adults, and previous uncontrolled data suggest divalproex sodium may be effective in preventing migraine in children and adolescents with acceptable tolerability.

METHODS

This was a 12-week, phase 3, randomized, placebo-controlled, double-blind, parallel-group, multicenter study in approximately 300 adolescents aged 12 to 17 years with migraine headaches. At the end of the baseline phase, subjects still meeting study criteria were randomized in a 1:1:1:1 ratio to receive divalproex sodium extended-release 250 mg, 500 mg, or 1000 mg once daily, or placebo. The primary efficacy variable was reduction from baseline in 4-week migraine headache rate for each active treatment group vs placebo. Standard safety assessments were conducted and testosterone and sex hormone-binding globulin levels were collected for postmenarchal females.

RESULTS

There was no statistically significant treatment difference between any divalproex sodium extended-release dose group and placebo for the primary efficacy variable, reduction from baseline in 4-week migraine headache rate. There were no statistically significant differences in adverse events between any active treatment group and placebo. A notable dose-related decrease in platelets was observed, and individuals in all 4 treatment groups had increases in ammonia levels; treatment differences in other laboratory variables were generally small. Among postmenarchal female subjects who were not taking hormonal contraceptives or other steroids, there was no statistically significant change in testosterone levels, but a statistically significant dose-related increase in sex hormone-binding globulin was observed.

CONCLUSIONS

In the current study, divalproex sodium extended-release did not differentiate from placebo in the prophylactic treatment of migraine headaches but was generally well-tolerated in adolescents aged 12 to 17 years.

A double-blind, randomized, placebo-controlled trial of divalproex extended-release in the treatment of bipolar disorder in children and adolescents

OBJECTIVE

To compare the efficacy and safety of divalproex extended-release (ER) to placebo in a 28-day double-blind study of bipolar disorder in children and adolescents and evaluate the safety of divalproex ER in a 6-month open-label extension study.

METHOD

In the double-blind study, 150 patients (manic or mixed episode, aged 10-17 years) with baseline Young Mania Rating Scale (YMRS) score of 20 or higher were randomized to once-daily placebo or divalproex ER, which was titrated to clinical response or serum valproate concentration of 80 to 125 microg/mL. Sixty-six patients enrolled in the extension study.

RESULTS

In the double-blind study, a treatment effect was not observed with divalproex ER based on change in mean YMRS score (divalproex ER -8.8 [n = 74]; placebo -7.9 [n = 70]) or secondary measures. Divalproex was similar to placebo based on incidence of adverse events. Four subjects treated with divalproex ER and three treated with placebo discontinued because of adverse events. Mean ammonia levels increased in the divalproex ER group, but only one patient was symptomatic. In the long-term study, YMRS scores decreased modestly (2.2 points from baseline). The most common adverse events were headache and vomiting.

CONCLUSIONS

The results of the study do not provide support for the use of divalproex ER in the treatment of youths with bipolar I disorder, mixed or manic state. Further controlled trials are required to confirm or refute the findings from this study.

Nursing children and adolescents with bipolar disorder: assessment, diagnosis, treatment, and management

TOPIC

The role of the mental health nurse in the assessment, diagnosis, treatment, and management of children and adolescents with bipolar disorder in community and hospital settings.

PURPOSE

In many areas of clinical practice, mental health nurses have more contact with service users than any other professional group. They are therefore well placed to support children and adolescents with bipolar disorder during first contact with primary care services, through engagement with specialist mental health services, and in accessing early intervention and crisis services. This paper summarizes the contribution that child and adolescent mental health nurses make to the care of children and adolescents with bipolar disorder.

SOURCES

This paper is based on evidence from systematic reviews; meta-analyses and best practice evidence from CINAHL; EMBASE; MEDLINE, PsychINFO; Cochrane Collaboration; National Institute for Health and Clinical Excellence; National Collaborating Centre for Mental Health; NHS Centre for Reviews and Dissemination; Oxford Centre for Evidence Based Medicine; United States Agency for Healthcare Research and Quality.

CONCLUSIONS

Child and adolescent mental health nurses work with children and adolescents who have bipolar disorder in a range of settings. These include community mental health services, hospitals, and schools. Due to the multidisciplinary nature of the treatment and management of bipolar disorder during childhood and adolescence, nurses have a major role to play in providing frontline assessment services, monitoring treatment, and delivering psychosocial interventions.

Divalproex sodium extended-release for the prophylaxis of migraine headache in adolescents: results of a stand-alone, long-term open-label safety study

OBJECTIVE

The objective of this long-term open-label study in adolescents was to assess the safety and tolerability of divalproex sodium extended-release in the prophylaxis of migraine headaches.

BACKGROUND

Two formulations of divalproex sodium have demonstrated efficacy in the prevention of migraine headaches in adults. However, no medications are currently approved for this indication in adolescents, and long-term safety data on agents for migraine prevention are lacking for this younger population. Therefore, the current study was conducted to assess the long-term safety and tolerability of divalproex extended-release in adolescents with migraine headaches.

METHODS

This was a 12-month, phase 3, open-label, multicenter study of adolescents aged 12 to 17 years with migraine headaches diagnosed by International Headache Society criteria. Divalproex sodium extended-release was initiated at 500 mg/day for 15 days then increased to 1000 mg daily, with subsequent adjustments permitted within a dosing range of 250-1000 mg daily. Study visits were conducted at days 1 and 15 and months 1, 2, 3, 6, 9, and 12. Safety was evaluated by adverse event collection, laboratory assessments, physical and neurological examinations, vital signs, electrocardiograms, the Udvalg for Kliniske Undersøgelser Side Effect Rating Scale, the Wechsler Abbreviated Scale of Intelligence, and the Behavioral Assessment Scale for Children. Efficacy was evaluated by following the number of migraine headache days reported in subjects' headache diaries over sequential 4-week intervals for the duration of the trial.

RESULTS

A total of 241 subjects were enrolled and treated. The most frequently reported adverse events were nausea (19%), vomiting (18%), weight gain (12%), nasopharyngitis (11%), migraine (10%), and upper respiratory tract infection (10%). Ten (4%) subjects experienced serious adverse events, and 40 (17%) subjects discontinued because of an adverse event. Increases in ammonia levels were observed. No other clinically significant changes were observed in laboratory values, vital signs, rating scales, or electrocardiograms. Median 4-week migraine headache days decreased 75% between the first and the fourth months of the study (from 4.0 to 1.0) and remained at or below this level for the remainder of the study.

CONCLUSIONS

In this long-term open-label study of adolescents with migraine, the safety and tolerability profile of divalproex sodium extended-release was consistent with findings from previous trials in adults, as well as 2 studies recently completed in adolescents. In general, divalproex sodium extended-release was well-tolerated in adolescents with migraine.

Current issues: women and bipolar disorder

While the treatment of bipolar disorder (BD) is typically complex, the treatment of women with bipolar disorder is even more challenging because clinicians must also individualize treatment based on the potential for pregnancy, drug interactions with oral contraceptives, and an increased risk of endocrine diseases that can either impact the course of illness or become manifest with some treatments. Women with BD should be checked for hypothyroidism, and if prescribed antidepressants, carefully watched for rapid cycling or a mood switch to mania, hypomania, or a mixed state. Several medications interact with oral contraceptives or increase the risk of developing polycystic ovary syndrome. Consideration of possible pregnancy is essential, and should be planned in advance whenever possible. Rates of recurrence have been shown to be equal in pregnant and nonpregnant women with BD. Risks of medication to the fetus at various points of development must be balanced against the risks of not treating, which is also detrimental to both fetus and mother. The postpartum period is a time of especially high risk; as many as 40% to 67% of women with BD report experiencing a postpartum mania or depression. The decision to breastfeed must also take into account the adverse impact of sleep deprivation in triggering mood episodes. In order to best address these issues, clinicians must be familiar with the data and collaborate with the patient to assess risks and benefits for the individual women and her family.

Metabolic syndrome in Italian patients with bipolar disorder

OBJECTIVE

This study aimed to evaluate the prevalence of metabolic syndrome (MetS) in Italian patients with bipolar disorder (BD) and to determine the sociodemographic and clinical correlates of MetS in this patient population.

METHOD

Subjects with BD I and II were included. Sociodemographic and clinical characteristics, lifestyle information (alcohol and smoking habits and rate of physical exercise) and comorbidity for cardiovascular diseases and diabetes were collected. Patients were assessed for MetS according to both National Cholesterol Education Program Adult Treatment Panel III and International Diabetes Federation (IDF) criteria.

RESULTS

MetS was evaluated in 99 patients out of 108 who were enrolled. MetS was present in 25.3% of the sample. Abdominal obesity was present in 50%, hypertension in 40%, high triglycerides in 34.7%, low HDL-C levels in 32.3% and fasting hyperglycemia in 11% of the sample. Prevalence of MetS was 30% when IDF criteria were employed. Of the investigated variables, age, duration of illness, rate of obesity and cardiovascular disease were higher in patients with MetS. After the regression analysis, only age and obesity were associated to MetS.

CONCLUSIONS

MetS is highly prevalent in Italian patients with BD. Our 25.3% prevalence rate is consistent with the 21-22% reported in other European studies and lower than that in U.S. studies. Elderly and obese patients with BD are at particularly high risk for MetS.

Weight gain and metabolic issues of medicines used for bipolar disorder

Patients with bipolar disorder are at high risk of gaining weight and developing metabolic illnesses, and pharmacologic treatment for the disorder may significantly increase this risk. This paper reviews the literature on the metabolic consequences of the medications used in bipolar disorder and describes the possible strategies to prevent, monitor, and treat the common metabolic illnesses that patients with bipolar disorder may develop during treatment.

Mood disorders and fertility in women: a critical review of the literature and implications for future research

A medline literature review of fertility and mood disorder articles published since 1980 was performed in order to critically review the literature regarding a relationship between mood disorders, fertility and infertility treatment. Previous studies suggests that mood disorders, both in the bipolar and unipolar spectrum, may be associated with decreased fertility rates. Most studies report that women seeking treatment for infertility have an increased rate of depressive symptoms and possibly major depression (none showed evaluated mood elevations). Many, but not all, studies found that depressive symptoms may decrease the success rate of fertility treatment. Treatments for infertility may independently influence mood through their effects on estrogen and progesterone, which have been shown to influence mood through their actions on serotonin. Studies are limited in scope and confounding variables are many, limiting the strength of the results. In conclusion, a range of existing studies suggests that fertility and mood disorders are related in a complex way. Future studies should use clinical interviews and standardized and validated measures to confirm the diagnosis of mood disorders and control for the variables of medication treatment, desire for children, frequency of sexual intercourse, age, FSH levels, menstrual cycle regularity in assessing an interrelationship between mood disorders and fertility.

Sodium valproate versus lamotrigine: A randomised comparison of efficacy, tolerability and effects on circulating androgenic hormones in newly diagnosed epilepsy

We have performed a randomised, prospective study to compare the efficacy and tolerability of sodium valproate (VPA) and lamotrigine (LTG) monotherapy, and their effects on circulating androgenic hormones, in newly diagnosed epilepsy. A total of 225 patients (116 male; median age 35 years, range 13-80 years) were followed-up at 6-weekly intervals until they reached an end-point (12 months' seizure freedom; withdrawal due to intolerable side-effects; lack of efficacy despite adequate dosing). Twelve month seizure-free rates were identical (47%) in the VPA (n=111) and LTG (n=114) treatment arms. More patients taking VPA withdrew from the study due to adverse events (26 VPA versus 15 LTG; p=0.046). Eight patients, all taking VPA, dropped out during the first 6 months due to weight gain. There were no changes in mean serum concentrations of testosterone, sex-hormone binding globulin and androstenedione or in the free androgen index after 6 or 12 months' treatment with either drug in 112 patients who fulfilled the criteria for hormone analysis. No difference in efficacy was found between VPA and LTG in our patients with newly diagnosed epilepsy. LTG appeared to be better tolerated. Neither drug appeared to alter the circulating levels of androgenic hormones.

Thirty years of clinical experience with carbamazepine in the treatment of bipolar illness: principles and practice

Carbamazepine began to be studied in a systematic fashion in the 1970s and became more widely used in the treatment of bipolar disorder in the 1980s. Interest in carbamazepine has been renewed by (i) the recent US FDA approval of a long-acting preparation for the treatment of acute mania; (ii) studies suggesting some efficacy in bipolar depression; and (iii) evidence of prophylactic efficacy in some difficult-to-treat subtypes of bipolar illness. A series of double-blind controlled studies of the drug were conducted at the US National Institute of Mental Health from the mid-1970s to the mid-1990s. This review summarises our experience in the context of the current literature on the clinical efficacy, adverse effects and pharmacokinetic interactions of carbamazepine. Carbamazepine has an important and still evolving place in the treatment of acute mania and long-term prophylaxis. It may be useful in individuals with symptoms that are not responsive to other treatments and in some subtypes of bipolar disorder that are not typically responsive to a more traditional agent such as lithium. These subtypes might include those patients with bipolar II disorder, dysphoric mania, substance abuse co-morbidity, mood incongruent delusions, and a negative family history of bipolar illness in first-degree relatives. In addition, carbamazepine may be useful in patients who do not adequately tolerate other interventions as a result of adverse effects, such as weight gain, tremor, diabetes insipidus or polycystic ovarian syndrome. We review our clinical and research experience with carbamazepine alone and in combination with lithium, valproic acid and other agents in complex combination treatment of bipolar illness. More precise clinical and biological predictors and correlates of individual clinical responsiveness to carbamazepine and other mood stabilisers are eagerly awaited.

Elevated rates of testosterone-related disorders in women with autism spectrum conditions

The androgen theory of autism proposes that autism spectrum conditions (ASC) are in part due to elevated fetal testosterone (FT) levels, which are positively correlated with a number of autistic traits and inversely correlated with social development and empathy. A medical questionnaire was completed by n=54 women with ASC, n=74 mothers of children with ASC, and n=183 mothers of typically developing children to test whether women with ASC have an increased rate of testosterone-related medical conditions, and to see whether mothers of children with ASC show similar abnormalities, as part of the 'broader autism phenotype'. Compared to controls, significantly more women with ASC reported (a) hirsutism, (b) bisexuality or asexuality, (c) irregular menstrual cycle, (d) dysmenorrhea, (e) polycystic ovary syndrome, (f) severe acne, (g) epilepsy, (h) tomboyism, and (i) family history of ovarian, uterine, and prostate cancers, tumors, or growths. Compared to controls, significantly more mothers of ASC children reported (a) severe acne, (b) breast and uterine cancers, tumors, or growths, and (c) family history of ovarian and uterine cancers, tumors, or growths. These results suggest current hormone abnormalities in women with ASC and their mothers. Direct investigations of serum testosterone levels and genetic susceptibility to high testosterone production or sensitivity in women with ASC would illuminate the origin of these conditions. The relationship between FT and current testosterone levels also needs to be clarified. The present results may be relevant to understanding the increased male risk to developing autism.

Observations on juvenile myoclonic epilepsy amongst ethnic Bengalees in West Bengal—An Eastern Indian State

BACKGROUND

Juvenile myoclonic epilepsy (JME) is not too uncommonly encountered in Indian neurological practice. A number of reports from different parts of India have documented the clinical phenomenology and EEG characteristics of this genetically determined epileptic syndrome. However, no study has yet been reported from the Eastern part of India and none done so far in patients in a specific ethnic group. Furthermore therapy response and follow up data are not available in detail in the Indian studies.

OBJECTIVE

To study disease expression, EEG characteristics and therapy response of JME patients in ethnic Bengalees in West Bengal, an Eastern Indian State, in a clinic based study.

MATERIAL AND METHODS

200 patients with JME attending the Neurology Department of the Institute have been followed up for 5 years and different parameters of disease expression as outlined above have been studied.

RESULTS

Overall clinical disease expression has been found to be similar in this clinic based study in ethnic Bengalees as compared to other reports from India and elsewhere. About 16% of patients showed a relative resistance to Valproate therapy. Hundred percent of patients in whom therapy withdrawal was attempted, relapsed within<1-2 years. Amongst female patients (132), 16 developed features of polycystic ovarian syndrome while on Valproate therapy. In over half of them, the symptoms regressed after successful switch over from Valproate to Clobazam. 12/132 female patients became pregnant during follow up and while on Valproate; teratogenic effect was evident in only one such patient.

CONCLUSIONS

Phenotypic variations in disease expression including therapy response have been noted within a single ethnic group of patients attending the clinic and might account for genetic heterogeneity noted in molecular genetic studies. JME cannot really be called a very 'benign' epileptic syndrome; recurrence after therapy withdrawal almost invariably occurs.

Practice parameter for the assessment and treatment of children and adolescents with bipolar disorder

This practice parameter reviews the literature on the assessment and treatment of children and adolescents with bipolar disorder. The parameter focuses primarily on bipolar 1 disorder because that is the type most often studied in juveniles. The presentation of bipolar disorder in youth, especially children, is often considered atypical compared with that of the classic adult disorder, which is characterized by distinct phases of mania and depression. Children who receive a diagnosis of bipolar disorder in community settings typically present with rapid fluctuations in mood and behavior, often associated with comorbid attention-deficit/hyperactivity disorder and disruptive behavior disorders. Thus, at this time it is not clear whether the atypical forms of juvenile mania and the classic adult form of the disorder represent the same illness. The question of diagnostic continuity has important treatment and prognostic implications. Although more controlled trials are needed, mood stabilizers and atypical antipsychotic agents are generally considered the first line of treatment. Although patients may respond to monotherapy, combination pharmacotherapy is necessary for some youth. Behavioral and psychosocial therapies are also generally indicated for juvenile mania to address disruptive behavior problems and the impact of the illness on family and community functioning.

Antidepressants and sexual dysfunction

OBJECTIVE

Many patients with depression suffer from sexual dysfunction and sexual dysfunction is a recognized side-effect of antidepressants. The aim of this review was to examine the prevalence of psychosexual dysfunction associated with antidepressants, and to review treatment options which are specific to the affected component of sexual functioning and antidepressants.

METHOD

Comprehensive literature review using Medline and Cochrane databases.

RESULTS

Up to 70% of patients with depression may have sexual dysfunction. Tricyclic antidepressants, selective-serotonin reuptake inhibitors and venlafaxine are most and the non-serotonergic antidepressants and duloxetine least likely to produce sexual dysfunction. Pharmacological treatment options include antidepressants less likely associated or 'antidotes' to reverse sexual dysfunction.

CONCLUSION

Sexual dysfunction may be a preventable or treatable side-effect of antidepressants. Patients need routinely to be asked about sexual function to identify problems early. If sexual dysfunction is ignored it may maintain the depression, compromise treatment outcome and lead to non-compliance.

Polycystic Ovary Syndrome and Mental Health: A Review

Although physical symptoms of polycystic ovary syndrome (PCOS) are increasingly recognized by practicing clinicians, little attention has focused on psychological correlates of this frequent endocrine disorder. This review of medical and psychological literature indicates that PCOS is associated with several mental health problems, including depression and anxiety, body dissatisfaction and eating disorders, diminished sexual satisfaction, and lowered health-related quality of life. Although the causal direction of these relationships has not been established, it is clear that effective and comprehensive treatment of women with PCOS must encompass careful attention to psychological symptomatology. Recommendations for the assessment of specific mental health problems, management of related physical concerns, and treatment of obesity among women with PCOS are presented.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians.

LEARNING OBJECTIVES

After completion of this article, the reader should be able to explain that, in addition to physiologic changes, women with polycystic ovary syndrome (PCOS) have various mental health problems and lowered health-related quality of life issues and state that treatment must address these concerns.

Valproate and copper accelerate TRH-like peptide synthesis in male rat pancreas and reproductive tissues

Treatment with valproate (Valp) facilitates the synthesis of TRH-like peptides (pGlu-X-Pro-NH(2)) in rat brain where "X" can be any amino acid residue. Because high levels of TRH-like peptides occur in the pancreas and pGlu-Glu-Pro-NH(2) (Glu-TRH) has been shown to be a fertilization promoting peptide, we hypothesized that these peptides mediate some of the metabolic and reproductive side effects of Valp. Male WKY rats were treated with Valp acutely (AC), chronically (CHR) or chronically followed by a 2 day withdrawal (WD). AC, CHR and WD treatments significantly altered TRH and/or TRH-like peptide levels in pancreas and reproductive tissues. Glu-TRH was the predominant TRH-like peptide in epididymis, consistent with its fertilization promoting activity. Glu-TRH levels in the epididymis increased 3-fold with AC Valp. Phe-TRH, the most abundant TRH-like peptide in the pancreas, increased 4-fold with AC Valp. Phe-TRH inhibits both basal and TRH-stimulated insulin release. Large dense core vesicles (LDCV's) contain a copper-dependent enzyme responsible for the post-translational processing of precursors of TRH and TRH-like peptides. Copper (500 microM) increased the in vitro C-terminal amidation of TRH-like peptides by 8- and 4-fold during 24 degrees C incubation of homogenates of pancreas and testis, respectively. Valp (7 microM) accelerated 3-fold the processing of TRH and TRH-like peptide precursors in pancreatic LDCV's incubated at 24 degrees C. We conclude that copper, an essential cofactor for TRH and TRH-like peptide biosynthesis that is chelated by Valp, mediates some of the metabolic and reproductive effects of Valp treatment via acceleration of intravesicular synthesis and altered release of these peptides.

Pharmacological interventions for bipolar youth: Developmental considerations

Despite the high prevalence rate, there have been relatively few controlled studies to systematically examine pharmacological treatments for children and adolescents with bipolar disorder. We review the differences in clinical characteristics between youth and adults with bipolar disorder and the extant literature of pharmacological treatments for children and adolescents with bipolar disorder, as well as discuss the effectiveness of pharmacological interventions for treating children and adolescents who are at familial risk for developing bipolar disorder. Although the number of controlled studies of youth with manic and mixed episodes is rapidly growing, there are few studies examining treatments for depression and the prevention of recurrent affective episodes in this population. Although children and adolescents with bipolar disorder commonly present with co-occurring psychiatric disorders, such as attention-deficit/hyperactivity disorder, there are limited data to guide the treatment of these patients. Recently, studies have begun to characterize prodromal manifestations of bipolar disorder and identify early intervention strategies for treating children and adolescents with an elevated risk for developing bipolar disorder.

Anticonvulsants in the treatment of bipolar mania

A series of antiepileptic drugs have been investigated in terms of their ability to treat mania (with later applications for the treatment of bipolar depression and prevention of relapses). These include divalproex, carbamazepine, oxcarbazepine, gabapentin, lamotrigine, levetiracetam, tiagabine, topiramate and zonisamide. Although these drugs are all antiepileptic in action, they bring about these effects by different mechanisms; in particular, their impact on GABA differs significantly. Perhaps for this reason, their impact on mania varies greatly, with double-blind significant results evident only for valproate, carbamazepine and oxcarbazepine. Only valproate and carbamazepine are approved by the US FDA for use in mania; oxcarbazepine has never been found significantly effective in large-scale studies. Of the other options, both gabapentin and topiramate failed in large-scale investigations; tiagabine failed in small sample reports. Although lamotrigine has been successful in the prevention of depression relapse in bipolar disorder, it has not been effective in treating mania. Finally, there are no findings of large scale double-blind studies on the use of levetiracetam and zonisamide. A review of the kinetics, side effects and complications of the antiepileptic drugs indicates that carbamazepine is useful, and has adverse event benefit over all other options. The potential of zonisamide awaits further testing.

Separate and concomitant use of lamotrigine, lithium, and divalproex in bipolar disorders

Expert consensus emphasizes the need for better recognition and accurate diagnosis of bipolar disorder. Current research on lithium, divalproex, and lamotrigine provides new insight into the effective management of this illness. Advances in identifying the mechanism of action of mood stabilization has focused on signaling pathways within the cell that are associated with neurotrophic effects. Clinical research has led to confirmatory evidence of the efficacy of lithium in all phases of bipolar disorder, with the greatest effects seen in the treatment and prevention of mania. Compared to divalproex, lithium also has been found to have greater efficacy in the prevention of suicide. Lamotrigine has emerged as a first line treatment for bipolar depression, which is an area of weakness for other mood stabilizers. Oral loading of divalproex leads to rapid stabilization of mania without imposing a greater adverse effect burden than conventional dosing. Because no agent is universally effective in all phases of the illness, combination therapy with two or more agents often is the best option.

New medication treatment options for bipolar disorders

OBJECTIVE

To assess new treatment options for bipolar disorders.

METHOD

Controlled studies of new treatments for bipolar disorders were identified by computerized searches and reviews of scientific meeting proceedings, and were compiled by drug category.

RESULTS

Two main categories of medications, newer anticonvulsants and newer antipsychotics, are yielding emerging new treatment options for bipolar disorders. Newer anticonvulsants have diverse psychotropic profiles, and although not generally effective for acute mania, may have utility for other aspects of bipolar disorders (e.g. lamotrigine for maintenance or acute bipolar depression), or for comorbid conditions (e.g. gabapentin for anxiety or pain, topiramate for obesity, bulimia, alcohol dependence, or migraine, and zonisamide for obesity). In contrast, newer antipsychotics generally appear effective for acute mania, and some may ultimately prove effective in acute depression (e.g. olanzapine combined with fluoxetine, quetiapine) and maintenance (e.g. olanzapine).

CONCLUSION

Emerging research is yielding new treatment options for bipolar disorders and comorbid conditions.

Bipolar disorders: special diagnostic and treatment considerations in women

Bipolar disorder in women presents special diagnostic and treatment challenges to the clinician. The presentation of female bipolar may resemble depressive disorders, comorbid Axis I disorders, Axis II personality disorders, behavioral dysregulation, or general medical disorders; thus, it is critically important for clinicians to assess for a history of hypomania or mania when determining diagnosis in any woman presenting with psychological symptoms. Several gender differences may exist in the epidemiology and symptomatology of bipolar disorder, and each must be kept in mind during assessment. Rapid cycling and mixed states have been associated with female gender and may present diagnostic challenges as each often presents as major depression. Symptoms of postpartum psychosis tend to differ from the symptoms typically seen in bipolar mania; therefore, if postpartum psychosis is actually a manifestation of bipolar disorder, accurate diagnosis depends upon a knowledge of these differences. Special treatment considerations for bipolar disorder in women involve interactions between the illness and the female reproductive cycle. A risk of fetal malformation exists when some mood-stabilizing agents are used during conception and/or during the first trimester of pregnancy. Neurobehavioral teratogenicity and neonatal toxicity is also possible. Careful treatment management is necessary to reduce the risks to the fetus/infant and to effectively manage bipolar disorder in the mother. In treating women with bipolar disorder, clinicians should discuss the issue of pregnancy and associated risks of treatment versus no treatment with every patient of reproductive age. Further studies are needed on gestational timing and exposure to mood-stabilizing agents, especially newer agents recently approved or currently being considered for the treatment of bipolar disorder.
