Take the T out, put the T in: Gender-affirming hormones in youth.

BACKGROUND: An increasing number of adolescents are seeking gender care at clinics and hospital programs, and requesting gender-affirming hormonal treatment. The interventions can either include suppression of testosterone and introduction of estrogen, or suppression of estrogen and introduction of testosterone. AIMS: This review article focuses on the psychosocial experiences of youth who have completed their endogenous puberty and are now requesting one of these two forms of gender-affirming hormonal treatment. We investigate the comparative profiles of these two subgroups of transgender/gender-expansive youth. MATERIALS AND METHODS: Review of research data, established standards of care and practice guidelines, and clinical observations. RESULTS: Differences and similarities are noted and discussed in several realms: gender-related experiences prior to receiving hormonal treatment; the relationship between the physical changes and psychological experiences that accompany the introduction of testosterone or suppression of testosterone with replacement with estrogen; the intrapersonal and interpersonal implications of the treatment; considerations of fertility preservation for future family building; the role of the family in the decision-making process prior to starting a course of hormone therapy; and the capacity of youth to make informed decisions about these partially irreversible medical interventions. DISCUSSION: Medical providers who offer gender-affirming hormonal care to youth should work with the family and allied professionals to assure that the youth's gender health is enhanced, barriers to care are removed, and mental health risks are reduced, whether the T is coming out or going in. CONCLUSION: The cohort of youth who come to medical providers after completing puberty, and request gender-affirming hormones in the form of increases or reductions in T have a great deal in common, and also extensive variation among them.

Growth, growth potential, and influences on adult height in the transgender and gender-diverse population.

The sexually dimorphic trait of height is one aspect of the experience of transgender and gender-diverse (TGD) individuals that may influence their gender dysphoria and satisfaction with their transition. In this article, we have reviewed the current knowledge of the factors that contribute to one's final adult height and how it might be affected in TGD youth who have not experienced their gonadal puberty in the setting of receiving gonadotropin-releasing hormone analog (GnRHa) and gender-affirming hormonal treatment. Additional research is needed to characterize the influence of growth and final adult height on the lived experience of TGD youth and adults and how to best assess their growth, predict their final adult height, and how medical transition can be potentially modified to help them meet their goals.

Menopausal Hormone Therapy and Suicide in a National Sample of Midlife and Older Women Veterans.

BACKGROUND: Among midlife and older women, menopause symptoms and menopausal hormone therapy have been linked to mental health disorders and other comorbidities related to suicide. However, the role of hormone therapy as a prognostic factor of suicide risk is largely unknown. OBJECTIVES: To examine associations between menopausal hormone therapy, suicide attempts, and suicide among midlife and older women Veterans. RESEARCH DESIGN: In this longitudinal analysis of national Veterans Health Administration data from women Veterans aged 50 years and above, we used Fine-Gray proportional hazards models to examine associations between menopausal hormone therapy (prescribed in 2012-2013) and incident suicide attempts and suicide (index date-2016). MEASURES: Menopausal hormone therapy and psychoactive medications from pharmacy records; suicide attempts and suicide from national suicide data repositories; demographic variables, medical and psychiatric diagnoses, and substance use disorders from electronic medical record data and International Classification Diagnoses-9-CM codes. RESULTS: In this national sample of 291,709 women Veterans (mean age 60.47, SD 9.81), 6% were prescribed menopausal hormone therapy at baseline. Over an average of 4.5 years, 2673 had an incident suicide attempt (93%) or death by suicide (7%). Adjusting for age, race, and medical diagnoses, menopausal hormone therapy was associated with increased risk of suicide attempt (hazard ratio 1.41; 95% confidence interval, 1.22-1.64) and over 2-fold increased risk of death by suicide (hazard ratio 2.47; 95% confidence interval, 1.58-3.87). Associations with death by suicide remained significant after accounting for psychiatric comorbidity and psychoactive medications. CONCLUSIONS: Menopausal hormone therapy may be an important indicator of suicide risk among midlife and older women.

Adherence, Attitudes and Beliefs of Growth Hormone Deficient Patients - A Questionnaire-based Cohort Study.

INTRODUCTION: GHD is a chronic and systemic disease requiring daily replacement of growth hormone (GHRT). Adherence and attitudes of adult GHD patients are not well known. We sought to assess patients' knowledge of growth hormone deficiency (GHD) in association with treatment adherence and attitudes regarding available and upcoming treatment options. METHODS: We performed a cross-sectional survey with a custom-made questionnaire at a single centre assessing data on demographics, knowledge of GHD, adherence and attitudes towards GHRT. RESULTS: Of 106 eligible patients actively followed for GHD 70 returned the completed survey (return-rate 66%, 34 m/36 f; age 56±14 years). 46 patients were actively treated, but almost one third (n=24) refused GHRT. 12 patients had participated in clinical trials with LAGH (long-acting growth hormone). Overall, patients with GHRT showed good adherence. Patients refusing GHRT mostly feared side effects and/or had a lack of information/perceived effect. Disease knowledge and level of education were higher in treated than untreated patients (p=0.023/0.017). Only 36% of respondents would initiate treatment with LAGH. Patients with prior LAGH experience and patients with childhood-onset GHD were more likely to adopt LAGH (p=0.048/0.031). DISCUSSION: Most often, misinformation causes patients to refuse GHRT. Possibly the understanding of their condition and consequences of non-treatment is limited. To improve adherence more focused educational and behavioural strategies may be needed. Willingness to begin a therapy with LAGH was lower than expected (36%). The reasons for reluctance against LAGH need to be elucidated.

Long-term effect of gender-affirming hormone treatment on depression and anxiety symptoms in transgender people: A prospective cohort study.

BACKGROUND: Cross-sectional studies show that transgender people are more likely than cisgender people to experience depression and anxiety before gender-affirming hormone treatment (GAHT). However, the effect of GAHT on mental health in transgender people, and the role of other factors that may have a predictive effect, is poorly explored. OBJECTIVES: Using a longitudinal methodology, this study investigated the effect of 18-month GAHT on depression and anxiety symptomatology and the predictors on mental health outcomes in a large population of transgender people. MATERIALS AND METHODS: Participants (n = 178) completed a socio-demographic questionnaire, the Hospital Anxiety and Depression Scale (HADS), the Multidimensional Scale of Perceived Social Support (MSPSS) and the Autism Spectrum Quotient-Short Version (AQ-Short) at pre-assessment (T0) and at 18 months after initiation of GAHT (T1). RESULTS: From T0 to T1, symptomatology was significantly decreased for depression (P < .001) and non-significantly reduced for anxiety (P = .37). Scores on the MSPSS predicted reduction in depression, while scores on the AQ-Short predicted reduction in anxiety. DISCUSSION: GAHT reduces symptoms of depression which are predicted by having higher levels of social support. Although anxiety symptoms also reduce, the changes are not significant and high levels of anxiety still remain post-GAHT. CONCLUSIONS: These results highlight the important mental health benefits of GAHT. Support services (professional, third sector or peer support) aiming at increasing social support for transgender individuals should be made available.

Quality of life in Klinefelter patients on testosterone replacement therapy compared to healthy controls: an observational study on the impact of psychological distress, personality traits, and coping strategies.

PURPOSE: We aimed to verify if 1 year-testosterone-replacement therapy could produce a psychopathological recovery and a satisfactory quality of life in Klinefelter syndrome (KS) patients compared to matched healthy controls. Further, we analyzed personality traits and coping strategies, an issue not yet examined in androgen-treated KS patients. We also enquired whether any of the sociodemographic and psychological variables might predict a patient's general and sexual life satisfaction. METHODS: The Quality of Life Enjoyment and Satisfaction Questionnaire and the Temperament and Character Inventory-Revised were administered to both 23 KS patients and matched healthy subjects. Psychopathology was investigated by the Symptom Checklist-90-Revised (SCL-90-R) and the Mini-mental State Examination. The COPE Inventory was used to identify cognitive and behavioral strategies to manage disease-related distress. RESULTS: In testosterone-treated KS patients, when compared with controls, SCL-90-R subscales analysis evidenced high psychological distress, mainly presented as obsessive thoughts, hanger-hostility, phobias, and psychoticism. Self-directedness and self-transcendence, along with the prevalent use of emotion-focused coping strategies, outlined the personality of our KS patients. Depression and somatization proved to be predictors of general life dissatisfaction. Depression, anger-hostility, and paranoid ideation, instead, emerged as predictors of sexual life dissatisfaction. CONCLUSION: Endocrinologists should cooperate with mental health providers to foster a better outcome of the disease in KS patients.

Motivation for and adherence to growth hormone replacement therapy in adults with hypopituitarism: the patients' perspective.

INTRODUCTION: While reasons for non-adherence in children requiring growth hormone (GH) replacement (GH-Rx) are well researched, few studies have investigated adherence in adult GH deficient patients. Against the background of the adverse medical sequelae of untreated severe GH deficiency (GHD) in adults, we explored adherence to GH-Rx and associated factors in this patient group. METHOD: Cross-sectional analysis including 107 adult patients with severe GHD on GH-Rx, 15 untreated GDH patients and 19 who had discontinued therapy. Patients completed self-developed ad hoc surveys on adherence to medication and GH-Rx, specific beliefs about GH-Rx, side effects and burden of injection, reasons for never receiving or dropping out of therapy, respectively. RESULTS: Adherence to GH-Rx was high (mean 15.8/18 points on the self-developed adherence score) and significantly correlated with general medication adherence. Higher age was significantly associated with better adherence to GH-Rx, while injection side effects, duration of treatment or device used were not. The most frequent reasons for not being on GH-Rx apart from medical reasons included fear of side effects, lack of belief in treatment effects and dislike of injections. In patients not on GH-Rx, the proportion of patients in employment was significantly smaller than in the treatment group, despite similar age and comorbidities. CONCLUSIONS: Adherence to GH-Rx was high for those patients on therapy. Instead of focusing on improving adherence in those adults already on GH-Rx, efforts should be undertaken to ally fear of side effects and provide education on positive treatment effects for those eligible but not receiving therapy.

Hormone therapy decision-making processes: Transgender youth and parents.

INTRODUCTION: This study explored how transgender (trans) youth and parents of trans youth made decisions around hormone therapy initiation as well as trans youth experiences of barriers to care. METHODS: Participants included 21 trans youth (ages 14-18) and 15 parents of trans youth who resided in British Columbia, Canada. Data for this grounded theory research consisted of transcripts and lifeline drawings collected through semi-structured interviews conducted August 2016 through February 2017. RESULTS: The decision-making processes of youth and of parents are illustrated in three-phase temporal models, starting with discovery, leading to (inter)action while seeking care, and reflection after hormone therapy initiation. Youth who sought hormone therapy were clear about their decision to access this care. Throughout these processes, youth experienced numerous parent- and system-related barriers to care. Youth with the lowest levels of parent support experienced more system barriers, with non-binary/genderfluid youth experiencing greater barriers and less support for hormone therapy than youth with binary genders. A new barrier identified in this study was health care provider imposed requirements for parental involvement and/or approval, which rendered some youth unable access to hormone therapy. CONCLUSIONS: Health care providers should be aware of the deliberation and information-seeking in which youth engage prior to seeking care as well as the temporally misaligned decision-making processes of youth and parents. Understanding the challenges trans youth experience due to insufficient parental support and system barriers can provide important context for health care providers striving to provide accessible, gender-affirming care and decision-making support for trans youth.

How sociophenomenology of the body problematises the 'problem-oriented approach' to growth hormone treatment.

This article examines how people who are shorter than average make sense of their lived experience of embodiment. It offers a sociophenomenological analysis of 10 semistructured interviews conducted in the Netherlands, focusing on if, how, and why height matters to them. It draws theoretically on phenomenological discussions of lived and objective space, intercorporeality and norms about bodies. The analysis shows that height as a lived phenomenon (1) is active engagement in space, (2) coshapes habituated ways of behaving and (3) is shaped by gendered norms and beliefs about height. Based on this analysis, the article challenges what we label as the 'problem-oriented approach' to discussions about growth hormone treatment for children with idiopathic short stature. In this approach, possible psychosocial disadvantages or problems of short stature and quantifiable height become central to the ethical evaluation of growth hormone treatment at the expense of first-hand lived experiences of short stature and height as a lived phenomenon. Based on our sociophenomenological analysis, this paper argues that the rationale for giving growth hormone treatment should combine medical and psychological assessments with investigations of lived experiences of the child. Such an approach would allow considerations not only of possible risks or disadvantages of short stature but also of the actual ways in which the child makes sense of her or his height.

Hormone use among Nepali transgender women: a qualitative study.

OBJECTIVES: There is a dearth of information on transgender individuals in Nepal, particularly studies exploring their use of hormone therapies. The objectives of this study therefore were to explore (1) how hormones are used, (2) types of hormones used and (3) side effects experienced by transgender women after hormone use. This is the first study of its kind in Nepal addressing this important public health issue. SETTING: The study was conducted in four districts of Nepal: Kathmandu, Sunsai, Banke and Kaski. DESIGN AND PARTICIPANTS: This qualitative study comprises eight focus group discussions (FGDs) and nine interviews. FGDs and three face-to-face interviews were held with transgender women aged 18 years and older and six interviews with stakeholders working with and advocating on behalf of this population. The study was conducted between September 2016 and March 2017. RESULTS: Our participants were young. The majority of FGD participants had completed school-level education and 40% had been using hormones for 1 to 3 years. Five overlapping themes were identified: (1) reasons and motivations for hormone use; (2) accessibility and use of hormones; (3) side effects; (4) utilisation of healthcare services and (5) discontinuation of hormone use. CONCLUSION: Hormone use was common in our sample. Most received information on hormone therapy online and through their peer networks. A few study participants sought doctors' prescriptions for hormone therapy, but hormones were more likely to be bought from local private pharmacies or abroad through friends. This kind of self-medication is associated with a range of risks to the physical and mental health of transgender individuals. Incorporating information, education and communication about hormone therapy into existing health promotion interventions targeted to this population may help transgender people to make better informed choices.

Making choices at menopause.

BACKGROUND: Menopause is a time of change in women's lives and an opportunity for health promotion. Women can present with a range of symptoms and concerns. OBJECTIVE: The aim of this article is to review the key components of the assessment of women who are perimenopausal or menopausal, and to discuss the benefits and risks of hormonal and non-hormonal treatments, thereby assisting clinicians to appropriately manage these women. DISCUSSION: The majority of women who are symptomatic can be offered menopausal hormone therapy (MHT). To ensure women can make an informed choice about whether to use MHT, it is important for them to receive balanced and accurate information about the benefits and risks. For women with contraindications to MHT, or women who prefer not to use hormones, non-hormonal and complementary options may be considered. New non-hormonal options are likely to be available in the future.

Does having Turner syndrome affect quality of life in Brazilian women compared to common population?

ABSTRACT Objectives We aimed to measure the quality of life (QoL) of patients with Turner syndrome (PTS) and determine the extent to which their clinical or laboratory alterations influence QoL compared to reference women (RW) of the same age range. Subjects and methods From Dec-2013 to Dec-2014, 90 participants were recruited. They were 18 years and older: 48 with Turner syndrome (TS) (PTS) and 42 without (RW). Recruited subjects completed the Portuguese version of Short Form 36 (SF-36) questionnaire, and blood was drawn to measure LH, FSH, oestradiol (E2), progesterone (P4), SHBG, and SDHEA (by ECLIA) and testosterone (by LC MS/MS). Results Age and schooling were similar between groups. The most common occupations for PTS were health worker, administration and education, and health worker or cashier for RW. Most participants were Catholic or Evangelical. Eighty-one percent (39/48) of cases used Hormonal Replacement Therapy (HRT), mostly transdermal (23/39). RW and PTS scored similarly on the SF-36 questionnaire. RW had higher oestradiol (p = 0,01), lower FSH (p = 0,01) and higher testosterone (p = 0,01) than PTS. Concentrations of P4, LH, SHBG or SDHEA were similar. Significant associations were found among QoL and hormones (E2 with Vitality and LH with Physical Role) only in the PTS group. Conclusions PTS do not consider that TS affects their QoL as measured by domains on the SF-36. Oestradiol was related with QoL, emphasising the importance of HRT.

Effect of cross-sex hormones on the quality of life, depression and anxiety of transgender individuals: a quantitative systematic review.

OBJECTIVE: The objective of the review was to evaluate the effectiveness of cross-sex hormone use in improving quality of life and the related measures of depression and anxiety in transgender individuals. INTRODUCTION: Transgender medicine as a specialty is still in its infancy and is beginning to attract more primary care providers. The use of hormones to aid in gender transition is expected to provide benefit with regard to quality of life, but there have been few high-quality studies. Two previous systematic reviews were found. One review included studies where participants had gender-affirming surgery, and the other review considered only prospective studies. Both reviews found a benefit with the use of hormones, despite the lack of high-quality studies. To describe outcomes specifically associated with hormone therapy, this review focused on patients who had not yet had surgical interventions, with an aim to inform primary care providers who are considering providing gender transition related-care in their office or clinic. INCLUSION CRITERIA: Eligible studies included participants who were transgender (trans) women, trans men or who did not identify with the gender binary and were using cross-sex hormones. This review only considered studies where hormone use was under medical supervision. Studies that included participants who already had any form of gender-affirming surgery were excluded, as were studies that did not use a validated tool to measure quality of life, depression or anxiety. METHODS: A comprehensive database search of PubMed, CINAHL, Embase and PsycINFO was conducted in August and September of 2017. The search for unpublished studies and gray literature included Google, the New York Academy of Medicine and the World Professional Association for Transgender Health (WPATH) Conference Proceedings. No date limits were used in any part of the search. Study selection, critical appraisal and data extraction were conducted by two independent reviewers using the JBI protocols, standardized critical appraisal and data extraction tools. RESULTS: Seven observational studies met the inclusion criteria for this review. The total number of transgender participants in all the included studies was 552. Population sizes in the studies ranged from 14 to 163. In general, the certainty of the findings was low to very low due to issues with imprecision and indirectness. The use of cross-sex hormones was associated with improved quality of life, depression and anxiety scores, although no causation can be inferred. CONCLUSIONS: Transgender participants who were prescribed cross-sex hormones had statistically significant scores demonstrating improvement on the validated scales that measured quality of life, anxiety and depression when compared to transgender people who had enrolled in a sex-reassignment clinic but had not yet begun taking cross-sex hormones. However, because the certainty of this evidence was very low to low, recommendations for hormone use to improve quality of life, depression and anxiety could not be made. High-quality research on this issue is needed, as is the development of a quality-of-life tool specific to the transgender population.

Transition memories: experiences of trans adult women with hormone therapy and their beliefs on the usage of hormone blockers to suppress puberty.

PURPOSE: In recent years, an increasing number of specialized gender clinics have been prescribing gonadotropin-releasing hormone (GnRH) analogs to adolescents diagnosed with gender dysphoria (GD) to suppress puberty. This paper presents qualitative research on the hormone therapy (HT) experiences of older trans-people and their views on puberty suppression. The main aim of this research was to explore the psychological aspects of hormonal treatments for gender non-conforming adults, including the controversial use of puberty suppression treatments. METHODS: Using a semi-structured interview format, ten adult trans-women were interviewed (mean age: 37.4) to explore their personal histories regarding GD onset and development, their HT experiences, and their views on the use of GnRH analogs to suppress puberty in trans-children and adolescents. RESULTS: the interview transcripts were analyzed using the consensual qualitative research method from which several themes emerged: the onset of GD, childhood experiences, experiences with puberty and HT, views on the puberty suspension procedure, and the effects of this suspension on gender identity and sexuality. CONCLUSIONS: The interviews showed that overall, the participants valued the new treatment protocol due to the opportunity to prevent the severe body dysphoria and social phobia trans-people experience with puberty. It seems that the risk of social isolation and psychological suffering is increased by the general lack of acceptance and stigma toward trans-identities in the Italian society. However, during gender transitions, they highlight the need to focus more on internal and psychological aspects, rather than over-emphasize physical appearance. This study gives a voice to an under-represented group regarding the use of GnRH analogs to suppress puberty in trans-individuals, and collected firsthand insights on this controversial treatment and its recommendations in professional international guidelines.

Predictors of Initiating Hormone Replacement Therapy in Postmenopausal Women: A Cross-Sectional Study.

OBJECTIVES: Some of the social factors were related to hormone replacement therapy. The purpose of this study is to determine hormone replacement therapy (HRT) rates and to illustrate social factors affecting hormone replacement therapy in postmenopausal women. MATERIAL AND METHODS: This study comprised a total of 1052 postmenopausal women, 926 of whom were reported menopausal symptoms and sought for the treatment. 432 of these 926 participants had treated their symptoms by receiving HRT. The data was collected with a data collection form prepared by the researcher by using face-to-face interview technique. In these analyses, chi-square and Backward Logistic regression analyses were used. RESULTS: The multivariate analyses indicated that the decision to seek treatment was influenced by a multitude of factors. These factors included location of hormone replacement therapy (OR: 12.32 [3.21-44.46] in university hospital and OR: 5.42 [2.43-13.26] in private hospital), information received about HRT (OR: 7.25 [2.14,-30.80]), physicians' counselling and involvement (OR: 5.24 [2.82-9.86]), knowledge of complications associated with HRT (OR: 6.21 [3.28-16.62]), and employment status (OR: 3.42 [1.86-5.58]). The current study identifies these factors affecting the HRT process in postmenopausal women. CONCLUSION: This study suggests that although the results do not demonstrate an exhaustive list of factors affecting the HRT process, they nonetheless provide evidence that the location participants applied for, physicians' counselling and involvement, participant employment status, and knowledge surrounding HRT may affect a woman's intent to receive HRT. Therefore, these results indicate that health professional influence and HRT awareness are important for HRT use. Suggestions for health care include informing women of the advantages and disadvantages of HRT to encourage popularity.

[Menopausal therapy: Modern view of the problem.]

The steady tendency of modernity improve the average life expectancy of a man dictates the necessity of implementing the anti-aging stratege, one of the stratege for women is menopausal therapy. Currently, the protective effect of menopausal therapy for cardiovascular system has been proven up to 60 years after it's implication in treatment. MHT is rarely used in Russia, largely due to the hormonophobia of patients and doctors especially with oncological risk. In contrary, recent studies indicate prolonged use of MHT decrease the risk of breast, ovarian, cervical and endometrial cancer. Morden microdosed medications that include dydrogesteron and progesterone as a progestational agent, also minimize the risk. Currently, there are no restictions on the duration of appucation. Total mortality decrease by 30% based on the result of meta-analysis 23 studies, which involve 39 049 people age until 60 years old with menopausal therapy.

Quality of Life in Hypoparathyroidism.

Patients with hypoparathyroidism have a multitude of physical, emotional, and cognitive complaints consistent with reduced quality of life (QOL). Impaired QOL in patients treated with conventional therapy with calcium and active vitamin D has been documented in epidemiologic (registry) studies, case-controlled studies, and surveys, and at baseline in clinical trials of parathyroid hormone (PTH). Treatment with PTH has been shown to improve QOL in some but not all studies.

Cognitive functioning and quality of life in patients with Hashimoto thyroiditis on long-term levothyroxine replacement.

OBJECTIVE: Intrinsic imperfections of thyroid hormone replacement therapy may affect long-term general well-being. In patients with Hashimoto thyroiditis (HT), cognitive functioning may be affected via altered thyroid hormones action as well as by the autoimmune process. The aim of this study was to evaluate cognitive function and quality of life (QoL) in patients on long-term levothyroxine replacement for HT in relation to thyroid function tests and TPO (thyroid-peroxidase) antibody (TPOAb) status. DESIGN: Retrospective cross-sectional study. PATIENTS AND MEASUREMENTS: One-hundred-and thirty patients with HT on long-term levothyroxine replacement and 111 euthyroid control subjects. Both groups were divided into two age subgroups, 20-49 years (N = 59 vs N = 79) and > 50 years (N = 71 vs N = 32). Evaluation included biochemical and neuropsychological tests, evaluating attention, global cognitive status, verbal and working memory, executive function, depression and anxiety, and quality of life. We used ANOVA and partial correlations to test for significant associations. RESULTS: FT4 (free-thyroxine), FT3 (free-triiodothyronine) levels and FT3/FT4 ratio were not different between patients and controls. Mean TSH (thyroid-stimulating hormone) was normal in all subjects but significantly higher in the patients (20-49 yrs:3.64 ± 2.74 vs 1.93 ± 1.10, >50 yrs:3.93 ± 2.84 vs 1.91 ± 0.90). Antibodies (TgAb,TPOAb) were higher in patients. Global cognitive function (MMSE-Mini mental state examination), conceptual tracking (TMT-Trail Making Test:A/B), verbal divergent thinking (like Phonemic fluency test), and anxiety and depression scores were significantly worse in patients vs controls. QoL was impaired in patients. there was a significant negative correlation between antibodies (TPOAb, TgAb) and quality in life (total SF36 score). CONCLUSION: Patients on long-term levothyroxine replacement show persistent impairments in both cognitive functioning and general well-being.

Effect of low-normal and high-normal IGF-1 levels on memory and wellbeing during growth hormone replacement therapy: a randomized clinical trial in adult growth hormone deficiency.

BACKGROUND: The aim of the present study was to investigate the effect of low-normal and high-normal levels of IGF-1 in growth hormone (GH) deficient adults on cognition and wellbeing during GH treatment. METHODS: A randomized, open-label, clinical trial including 32 subjects receiving GH therapy for at least 1 year. Subjects were randomized to receive either a decrease (IGF-1 target level of - 2 to - 1 SDS) or an increase of their daily GH dose (IGF-1 target level of 1 to 2 SDS) for a period of 24 weeks. Memory was measured by the Cambridge Neuropsychological Test Automated Battery, selecting the Pattern Recognition Memory task and the Spatial Working Memory. Wellbeing was measured as mood by the Profile of Moods States questionnaire, and quality of life by the Nottingham Health Profile and QoL Assessment in GH Deficiency in Adults questionnaires. RESULTS: Data from 30 subjects (65.6% male, mean age 46.6 (9.9 SD) years), who fulfilled the target levels, were analyzed. Females in the low dose treatment arm were found to have a better working memory and a better strategic memory control after 24 weeks as opposed to the females in the high treatment arm. With respect to mood, the decrease in IGF-1 levels in females within the low treatment arm was associated with more fatigue and less vigor. CONCLUSIONS: The adjustment of GH dose in female patients seems to have a narrow window. A dose too high may impair prefrontal cognitive functioning, while a dose too low may result in decreased vigor. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov , number NCT01877512.
