Psychological profile and quality of life in patients with acromegaly in Greece. Is there any difference with other chronic diseases?

Quality of life in patients with acromegaly: a scoping review

PURPOSE

To evaluate the available evidence regarding the quality of life (QoL) in patients with acromegaly, by synthesizing the psychosocial factors of QoL, QoL measures, and complementary interventions targeting QoL.

METHODS

A scoping review was conducted using the PRISMA-ScR guideline. We searched six English databases (PubMed, Embase, CINAHL, Scopus, Web of Science, and the Cochrane Library) from the inception to August 21, 2023. We included observational studies involving psychosocial factors and complementary interventions targeting QoL (concept) in patients with acromegaly (population) in any setting (context). The design characteristics, psychosocial factors, measures, details of interventions, and outcomes of included studies were described in detail.

RESULTS

Twenty-one studies were identified, including sixteen cross-sectional studies and five interventional studies. Ten categories of psychosocial factors that are associated with QoL in acromegaly. Depression and anxiety were the most frequent psychosocial factors. Seven different validated QoL measures were used. AcroQoL was the most common measure. Two categories of complementary interventions targeting QoL were identified including psychological and exercise interventions.

CONCLUSIONS

Our scoping review provides a reasonably clear picture of the current research status of QoL in acromegaly. However, this review also highlights the need to deepen understanding of QoL and psychosocial factors in the future, as well as conduct longitudinal research and qualitative research to clarify the changing trends of psychosocial factors and specific experiences of patients. Further, more potential clinical complementary interventions are needed to improve QoL for patients with acromegaly.

The effect of coping strategies on health-related quality of life in acromegaly patients

PURPOSE

Patients with acromegaly oftentimes exhibit a reduced physical and psychological health-related quality of life (HRQoL). Maladaptive coping styles are associated with poor HRQoL in a number of diseases and patients with pituitary adenomas in general exhibit less effective coping styles than healthy controls. This study aimed to assess coping strategies in acromegaly patients in order to explore leverage points for the improvement of HRQoL.

METHODS

In this cross-sectional study, we administered self-report surveys for coping strategies and HRQoL (Short Form SF-36, Freiburg questionnaire on coping with illness, FKV-LIS) in patients with acromegaly. These were set into relation with a variety of health variables.

RESULTS

About half of the 106 patients (44.3% female) with a mean age of 56.4 ± 1.3 years showed impaired physical and psychological HRQoL on average 11.2 years after the initial diagnosis. Body mass index, age at survey date and concomitant radiotherapy explained 27.8% of the variance of physical HRQoL, while depressive coping added an additional 9.2%. Depressive coping style and trivialization and wishful thinking were pivotal predictors of an impaired psychological HRQoL with a total explained variance of 51.6%, whereas patient health variables did not affect psychological HRQoL.

CONCLUSION

Our results show that maladaptive coping styles have a substantial negative impact on psychological HRQoL in patients with acromegaly, whereas physical HRQoL is influenced to a lesser extent. Specialized training programs aimed at improving coping strategies could reduce long-term disease burden and increase HRQoL in the affected patients.

Risk of depression in patients with acromegaly in Korea (2006-2016): a nationwide population-based study

BACKGROUND

An increased prevalence of depression has been reported in patients with acromegaly. However, most studies included a relatively small sample size owing to the rarity of acromegaly. We aimed to investigate the risk of depression in patients with acromegaly using the Korean National Health Information Database (NHID).

METHODS

The data of patients with acromegaly in 2006-2016 were collected from the rare incurable disease registry of the NHID. Patients with acromegaly were matched with control participants without acromegaly for age and sex in a 1:5 ratio.

RESULTS

Patients who did not receive treatment for acromegaly had a significantly increased risk of depression (hazard ratio [HR]: 1.43, 95% confidence interval [CI]: 1.12-1.82). However, the risk of depression did not increase in patients who received treatment for acromegaly. The multiple Cox regression analysis showed that the risk of depression was significantly higher in the untreated group than in the control group during the first 3 years of observation (HR: 1.829, 95% CI: 1.305-2.563). However, after a time lag of over 3 years, the risk of depression decreased in the untreated group, which is similar to that in the control group.

CONCLUSION

Our nationwide study suggests that patients who did not receive treatment for acromegaly have a higher risk of depression compared with controls. The untreated acromegaly patients should be monitored for the development of depression, especially in the early years after diagnosis. These results could serve as a basis for developing screening strategies to mitigate depression in acromegaly patients.

The socioeconomic burden of acromegaly

Acromegaly is a rare and insidious disease characterized by chronic excess growth hormone, leading to various morphological changes and systemic complications. Despite its low prevalence, acromegaly poses a significant socioeconomic burden on patients and healthcare systems. This review synthesizes the current state of knowledge on the psychosocial burden, disability, impact on daily life, and cost of acromegaly disease, focusing on the quality of life, partnership, medical care and treatment afflictions, participation in daily activities, professional and leisure impairment, and cost of treatment for acromegaly and its comorbidities. It also examines management strategies, coping mechanisms, and interventions aimed at alleviating this burden. A comprehensive understanding of the extent of the socioeconomic burden in acromegaly is crucial to develop effective strategies to improve treatment and care. Further research is warranted to explore the myriad factors contributing to this burden, as well as the efficacy of interventions to alleviate it, ultimately enhancing the quality of life for patients with acromegaly.

Questionnaire and tools: clinical powerful instrument in acromegaly diagnosis and management

PURPOSE

Acromegaly is a rare chronic disease characterized by systemic comorbidity and reduced quality of life. Although achieving biochemical control has always been the primary goal of acromegaly therapy, recent evidence has shown that the traditional assessment does not adequately capture the complexity of symptoms and patients' perception. These findings result in the need to improve a fast decision-making process of the clinician, who should not only take into account biochemical-instrumental criteria, but also patients' symptoms. With the aim of supporting the clinician in the diagnostic and therapeutic decision-making process several disease-specific tools have been developed. The aim of this review is to provide a description of the acromegaly-specific tools, presenting their main features, their application in daily practice, and their efficacy and utility.

METHODS

A systematic search of Medline/PubMed, ISI-Web of Knowledge, and Google Scholar databases was done.

RESULTS

Specific instruments and questionnaires have recently been developed to assist clinicians in the assessment of acromegaly. These are either Patient-Reported Outcome tools, such as Acromegaly Quality of Life Questionnaire (AcroQoL) and Pain Assessment Acromegaly Symptom Questionnaire (PASQ), or Clinician-Reported Outcome tools, such as ACROSCORE, SAGIT^® and Acromegaly Disease Activity Tool (ACRODAT^®). Such tools are extremely flexible and, therefore, have been widely adopted by endocrinologists and other professionals, so much so that they have also been included as recommendations in the 2018 international guidelines.

CONCLUSION

Questionnaires and tools are useful in the management of acromegaly patients. They help clinicians evaluate patients' symptoms and could assist in the evaluation of disease activity.

Psychological complications in patients with acromegaly: relationships with sex, arthropathy, and quality of life

PURPOSE

Current treatment of acromegaly restores a normal life expectancy in most cases. So, the study of persistent complications affecting patients' quality of life (QoL) is of paramount importance, especially motor disability and depression. In a large cohort of acromegalic patients we aimed at establishing the prevalence of depression, to look for clinical and sociodemographic factors associated with it, and to investigate the respective roles (and interactions) of depression and arthropathy in influencing QoL.

METHODS

One hundred and seventy-one acromegalic patients (95 women and 76 men, aged 20-85 years) among those recruited in a cross-sectional Italian multicentric study were investigated. Each patient filled in three validated questionnaires: AcroQoL, WOMAC (measuring articular pain, stiffness and functionality), and AIMS (evaluating articular symptoms and depression).

RESULTS

A very high (up to 28%) depression rate was detected in acromegalic subjects. Two patients showing pathological AIMS depression scores, committed suicide during the three years observational period. In our population poor psychological status was significantly associated with female sex. Furthermore, a significant strong correlation was found between AIMS depression score and WOMAC score. Both depression and arthropathy-related motor disability turned out to independently contribute with similar strength to the impairment of QoL.

CONCLUSIONS

We report a high prevalence of depression in acromegaly, which is associated with female sex and arthropathy. Both depression and arthropathy strongly and independently contribute to the impaired QoL of patients. Our study shows that assessment and monitoring of psychological status is mandatory in acromegaly, also suggesting an inexpensive tool for this assessment.

The clinical complexity of patients with acromegaly

OBJECTIVES

The main aim of the study was to investigate the factors related to the biopsychosocial complexity in the group of patients with acromegaly with different disease activity.

METHODS

A cross-sectional observational study was performed. First, a linguistic adaptation of the INTERMED - self-assessment questionnaire (IMSA) and after that the assessment of the biopsychosocial complexity among patients with acromegaly and the factors which relate to the complexity was made. The following tools were used to assess: biopsychosocial complexity: The INTERMED -self-assessment (IMSA); quality of life: The World Health Organization Quality of Life - BREF (WHOQoL) and Acromegaly Quality of Life questionnaire (AcroQol); mental state: The General Health Questionnaire - 28 (GHQ-28).

RESULTS

The final analysis included 71 patients. According to the principal component analysis the mental state (GHQ-28) and the quality of life (AcroQol) are the most important factors related to the clinical complexity among patients with acromegaly. In the model created by a stepwise regression analysis for the total IMSA score higher growth hormone (GH) concentration, longer illness duration, and better general quality of life were included as the protective factors of the clinical complexity. By contrast, a high score in the severe depression subscale of GHQ-28 was a factor of higher clinical complexity.

CONCLUSION

The mental state and quality of life are the most important determinants of the clinical complexity in the group of patients with acromegaly whereas the biochemical normalization is of lesser importance.

Patterns of Quality of Life and Perceived Satisfaction in Adults and Elderly in Spain: Daily Practices, Life Experiences and Psychological Profiles

A study was carried out with the purpose of determining the day-to-day practices, positive and stressful life experiences, and psychological profiles that underpin different perceptions of quality of life and perceived satisfaction. A total of 1095 adults and elderly people from Spain participated in the study. An online instrument designed using the tool Google Forms was administered to them. Descriptive and multivariate analysis was performed using the general linear model (GLM). Three types of finding were obtained. First, we identified everyday practices that promote perceived quality of life and perceived satisfaction. Second, we established the relationship between certain positive and stressful life experiences, their consequences, and different perceptions of quality of life and perceived satisfaction. Finally, we identified the distinguishing psychological profiles associated with these constructs. The results obtained here can contribute to the development of more successful psychological and social interventions. They reveal a set of indicators that, based on empirical evidence, should be part of any intervention design.

Stigma and unhealthy psychological characteristics in patients with acromegaly: A cross-sectional study and identification of the associated factors

BACKGROUND

Stigma, besides aggravating the damage caused by the disease, may also lead to unhealthy characteristics in patients and unhealthy situations in society. Individuals with acromegaly disease may suffer from stigma concerns, and the associated factors remain largely unknown. Therefore, the present cross-sectional study aimed to investigate the levels of perceived stigma in patients with acromegaly and explore the associated factors.

METHODS

A total of 138 patients with acromegaly were evaluated for having stigma using five previously validated scales: (i) the Stigma Scale for Chronic Illness, (ii) the Hamilton Anxiety Scale, (iii) the Rosenberg Self-Esteem Scale, (iv) the Body Image Concern scale, and (v) the Acromegaly Quality of Life scale. The potential determinants of stigma were evaluated using the univariate statistical analysis. A multivariate linear regression model was adopted to assess the predictors of stigma in patients with acromegaly. Pearson's correlation analysis was performed to analyze the relationship between stigma and the quality of life of the patients.

RESULTS

Among the 138 respondents, 102 provided consent for participation.The evaluated patients exhibited critically high levels of perceived stigma. The multiple regression analysis revealed high BMI, serious body image concerns, inferiority complex personality, and critical levels of anxiety as the potential predictors of stigma in patients with acromegaly. The overall stigma and internalized stigma were significantly correlated with QoL in these patients.

CONCLUSION

The patients with acromegaly exhibited critically high levels of perceived stigma, which led to psychological distress and disruptions in their daily lives. This finding highlights the importance of addressing the stigma concerns and the necessity for providing additional support to these patients in this regard during follow-up sessions. Further research should focus on developing intervention strategies to decrease the levels of perceived stigma in patients with acromegaly to promote their quality of life and for the psychosocial rehabilitation of these patients.

Surgically treated acromegaly patients have a similar quality of life whether controlled by surgery or requiring additional medical therapy (QuaLAT Study)

PURPOSE

There is no consensus on quality of life (QOL) in patients with acromegaly requiring medical treatment after surgery compared with those achieving remission by surgery alone.

METHODS

QuaLAT is a cross-sectional study comparing QOL in surgery-only treated acromegaly patients versus those requiring medical treatment post-surgery. Patients attending clinics were identified and divided into-Group 1: patients who had surgery only and were in biochemical remission, Group 2: all patients on medical treatment post-surgery, Group 3: patients from Group 2 with biochemical control. Participants were asked to fill three questionnaires; Acromegaly Quality of Life Questionnaire (ACROQOL), 36-Item Short Form Survey (SF36), and Fatigue Severity Scale (FSS).

RESULTS

There were 32 patients in Group 1 and 25 in Group 2. There was no difference in QOL scores between groups 1 and 2, as measured by ACROQOL (mean difference [MD] = - 2.5, 95% CI - 16.6 to 11.6; p = 0.72), SF36v2 [Physical component score (PCS) MD = - 4.9, 95% CI - 10.9 to 1.2; p = 0.12; mental component score MD = - 3.0, 95% CI - 10.5 to 4.4; p = 0.44], or FSS (MD = - 0.004, 95% CI - 1.14 to 1.33; p = 0.1). Comparison between groups 1 and 3 however showed that PCS (and 3 subdomains) was significantly better in group 3 (MD = - 8.3, 95% CI - 14.8 to -1.8; p = 0.01). All three QOL scores were lower when compared with healthy controls.

CONCLUSIONS

Medical treatment not only achieves a QOL comparable to surgery, it may also be associated with better QOL in physical subdomains. When compared with healthy controls, QOL remains worse in treated acromegaly patients compared to controls.

Quality of Life in Patients with Acromegaly - A Romanian Single Center Cross-Sectional Study

CONTEXT

Acromegaly, a severe condition characterized by excessive and unmodulated secretion of growth hormone, leads to morphologic disturbances and multisystem complications.

OBJECTIVE

The purpose of this study was to evaluate the quality of life (QOL) in patients with acromegaly compared to matched obese patients.

DESIGN

This was an observational cross-sectional study.

SUBJECTS AND METHODS

We enrolled 49 patients with acromegaly and 49 obese patients. AcroQoL (acromegaly QoL questionnaire) was applied to all patients and IGF-1 (type 1 insulin-like growth factor 1) was measured.

RESULTS

Patients with acromegaly had a worse QoL compared to patients with obesity (score= 77(53-86) vs. 96(90-102), p<0.001). In the group of patients with acromegaly, there was no difference in the QoL regarding the activity of the disease (active, controlled, or cured). Men had a higher AcroQoL score than women (score= 88(55-95) vs. 74(52.75-82), p=0.02), but there was no difference between patients with microadenomas and the ones with macroadenomas (score= 82(66-88.5) vs. 73(55-83), p=0.136). The most frequent complications were cardiovascular complications (81.63%), articular complications (73.46%), dyslipidemia (65.30%) and digestive complications (63.26%).

CONCLUSIONS

Despite complex treatment and hormonal control, the presence of complications reduces the quality of life in patients with acromegaly, even when compared with obese patients.

Differences in quality of life between genders in acromegaly

Objective

To study the impact of secondary mental disorders in patients affected with acromegaly and correlate them with quality of life (QoL) and disease status.

Design

An observational transversal descriptive and comparative study that evaluates QoL's impact due to secondary mental disorders in affected Mexicans with acromegaly using AcroQoL and SF‐36 instruments. Correlation of the results with the disease's biochemical status was performed. According to Beck's scales, anxiety and depression analyses evaluate QoL's impact, and its gender variability is described.

Results

Eighty‐five patients with diagnoses of acromegaly were included. The mean age was 43.18 years, 47 being women (55.29%). The mean age at diagnosis was 37.95 years, with no difference between men and women. AcroQoL and SF‐36 global and sub‐domain scores differed significantly between men and women, the latter having lower global and individual sub‐domain scores. The mean score of QoL, according to AcroQoL, is 59.40. In women, the mean values are less (55.13) than men (64.68), p = 0.021. The sub‐domain analyses’ scores in physical, appearance and social relationships were less in women (53.21; 47.34; 62.32) than men (62.68; 56.76; 73.87) p = 0.044, 0.069 and 0.013, respectively. Higher Beck's Depression Inventory (BDI) and Beck's Anxiety Inventory (BAI) scores correlated with lower QoL as assessed by global and individual sub‐domain scores. Women presented significantly higher BDI and BAI mean scores when compared to men regardless of their biochemical status. Anxiety (p = 0.027) and depression (p < 0.001) severity were higher in women compared to men.

Conclusion

Correlations between female gender, depression/anxiety scores and QoL require further validation. There is much to be routinely done to improve secondary psychopathology in patients affected by this disease. The need for mental status screening at diagnosis should be emphasized to identify secondary mental illnesses to improve QoL with its treatment.

Pereira-Lima JF, da C. Oliveira M. Health-related Quality of Life in Acromegaly Patients: Results from Generic and Disease-specific Questionnaires

INTRODUCTION

Acromegaly is associated with high morbidity, but still controversial impact on the overall quality of life (QoL).

MATERIAL AND METHODS

We evaluated QoL using a generic (SF-36) and a disease-specific questionnaire (AcroQoL) in an acromegalic cohort.

RESULTS

Sixty-nine patients answered the questionnaires and had their records reviewed. In the SF-36 questionnaire, except for the Social Aspects domain, all others revealed a reduction in scores from 9.7 to 38.9%, when compared to the non-acromegalics. The cure was positively correlated with mental health (P = 0.023) and drug control was correlated with mental health (P = 0.023) and functional capacity (P = 0.013). In the AcroQoL questionnaire, the mean scores ranged from 54.7% to 72.8%. The use of antidepressants correlated with lower scores on the total AcroQoL (P = 0.039) and physical complaints (P = 0.003). The growth hormone value at diagnosis showed an inverse correlation with the total AcroQoL score (P = 0.014), Appearance Issues subscale (P = 0.081), and Personal Relations (P = 0.002). IGF-1 values at diagnosis and at the last visit showed no statistical correlation with any of the questionnaires.

CONCLUSION

The finding of a reduction in QoL scores with both SF-36 and AcroQoL allows us to suggest this evaluation as part of the initial assessment and follow-up in acromegaly, to act globally on the individual's health condition.

Systemic Complications of Acromegaly and the Impact of the Current Treatment Landscape: An Update

Acromegaly is a chronic systemic disease with many complications and is associated with increased mortality when not adequately treated. Substantial advances in acromegaly treatment, as well as in the treatment of many of its complications, mainly diabetes mellitus, heart failure, and arterial hypertension, were achieved in the last decades. These developments allowed change in both prevalence and severity of some acromegaly complications and furthermore resulted in a reduction of mortality. Currently, mortality seems to be similar to the general population in adequately treated patients with acromegaly. In this review, we update the knowledge in complications of acromegaly and detail the effects of different acromegaly treatment options on these complications. Incidence of mortality, its correlation with GH (cumulative exposure vs last value), and IGF-I levels and the shift in the main cause of mortality in patients with acromegaly are also addressed.

Cognitive-behavioral therapy improves the quality of life of patients with acromegaly

BACKGROUND

The delayed diagnosis, altered body image, and clinical complications associated with acromegaly impair quality of life.

PURPOSE

To assess the efficacy of the cognitive-behavioral therapy (CBT) technique "Think Healthy" to increase the quality of life of patients with acromegaly.

METHODS

This non-randomized clinical trial examined ten patients with acromegaly (nine women and one man; mean age, 55.5 ± 8.4 years) from a convenience sample who received CBT. The intervention included nine weekly group therapy sessions. The quality of life questionnaire the 36-Item Short Form Survey (SF-36) and the Beck Depression Inventory (BDI) were administered during the pre- and post-intervention phases. The Wilcoxon signed-rank test was performed to assess the occurrence of significant differences.

RESULTS

According to the SF-36, the general health domain significantly improved (d'  = - 0.264; p = 0.031). The mental health domain improved considerably (d'  = - 1.123; p = 0.012). Physical functioning showed a non-significant trend toward improvement (d'  = - 0.802; p = 0.078), although four of the five patients who showed floor effects improved and remained at this level. Regarding emotional well-being, five patients showed floor effects and four improved, and the condition did not change among any of the four patients who showed ceiling effects. No significant changes were found with regard to the other domains. No significant differences in the BDI were found before or after the intervention.

CONCLUSION

The technique presented herein effectively improved the quality of life of patients with acromegaly with different levels of disease activity, type, and treatment time.

Higher Income and Integration into the Workforce Are the Main Factors Associated with Quality of Life in Acromegalic Patients in Northeastern Brazil

OBJECTIVE

To identify the factors associated with quality of life in patients with acromegaly with follow-up at the referral service in neuroendocrinology of the state of Maranhão, northeast Brazil.

METHODS

The Acromegaly Quality of Life Questionnaire (Acro-QoL) was used. Factors independently associated with quality of life were identified using multivariate linear regression, with p values < 0.05 considered significant.

RESULTS

The multivariate linear regression analysis indicated a positive association between being integrated into the job market and quality of life scores in the overall domain (β = 0.288, p = 0.003), psychological domain (β = 0.291, p = 0.032), and personal relationship domain (β = 0.314, p = 0.019). We also observed a positive association with income and the quality of life scores in all domains as follows: overall domain (β = 0.037, p = 0.003), physical domain (β = 0.988, p = 0.001), psychological domain (β = 0.342, p = 0.008), physical appearance domain (β = 0.270, p = 0.049), and personal relationship domain (β = 0.315, p = 0.012).

CONCLUSION

For patients with acromegaly living in one of the least developed regions of Brazil, integration into the job market and a higher income were associated with a better quality of life.

Growth hormone deficiency in treated acromegaly and active Cushing's syndrome

Growth hormone deficiency (GHD) in adults is characterized by reduced quality of life and physical fitness, skeletal fragility, increased weight and cardiovascular risk. It may be found in (over-) treated acromegaly as well as in active Cushing's syndrome. Hypopituitarism may develop in patients after definitive treatment of acromegaly, although the exact prevalence of GHD in this population is still uncertain because of limited awareness, and scarce and conflicting data so far available. Because GHD associated with acromegaly and Cushing's syndrome may yield adverse consequences on similar target systems, the final outcomes of some complications of both acromegaly and Cushing's syndrome may be further affected by the occurrence of GHD. It is still largely unknown, however, whether GHD in patients with post-acromegaly or active Cushing's syndrome (e.g. pharmacologic glucocorticoid treatment) may benefit from GH replacement. We review the diagnostic, clinical and therapeutic aspects of GHD in adults treated for acromegaly and in those with active Cushing's syndrome.

Predictors of Quality of Life in Acromegaly: No Consensus on Biochemical Parameters

BACKGROUND

Quality of life (QoL) in patients with acromegaly is reduced irrespective of disease state. The contributions of multifactorial determinants of QoL in several disease stages are presently not well known.

OBJECTIVE

To systematically review predictors of QoL in acromegalic patients.

METHODS

Main databases were systematically searched using predefined search terms for potentially relevant articles up to January 2017. Inclusion criteria included separate acromegaly cohort, non-hereditary acromegaly, QoL as study parameter with clearly described method of measurement and quantitative results, N ≥ 10 patients, article in English and adult patients only. Data extraction was performed by two independent reviewers; studies were included using the PRISMA flow diagram.

RESULTS

We identified 1,162 studies; 51 studies met the inclusion criteria: 31 cross-sectional observational studies [mean AcroQoL score 62.7 (range 46.6-87.0, n = 1,597)], 9 had a longitudinal component [mean baseline AcroQoL score 61.4 (range 54.3-69.0, n = 386)], and 15 were intervention studies [mean baseline AcroQoL score 58.6 (range 52.2-75.3, n = 521)]. Disease-activity reflected by biochemical control measures yielded mixed, and therefore inconclusive results with respect to their effect on QoL. Addition of pegvisomant to somatostatin analogs and start of lanreotide autogel resulted in improvement in QoL. Data from intervention studies on other treatment modalities were too limited to draw conclusions on the effects of these modalities on QoL. Interestingly, higher BMI and greater degree of depression showed consistently negative associations with QoL. Hypopituitarism was not significantly correlated with QoL in acromegaly.

CONCLUSION

At present, there is insufficient published data to support that biochemical control, or treatment of acromegaly in general, is associated with improved QoL. Studies with somatostatin receptor ligand treatment, i.e., particularly lanreotide autogel and pegvisomant have shown improved QoL, but consensus on the correlation with biochemical control is missing. Longitudinal studies investigating predictors in treatment-naive patients and their follow-up after therapeutic interventions are lacking but are urgently needed. Other factors, i.e., depression and obesity were identified from cross-sectional cohort studies as consistent factors associated with poor QoL. Perhaps treatment strategies of acromegaly patients should not only focus on normalizing biochemical markers but emphasize improvement of QoL by alternative interventions such as psychosocial or weight lowering interventions.

The quality of life in acromegalic patients with biochemical remission by surgery alone is superior to that in those with pharmaceutical therapy without radiotherapy, using the newly developed Japanese version of the AcroQoL

PURPOSE

To develop a Japanese version of the acromegaly quality of life (QoL) questionnaire (AcroQoL) and investigate the factors associated with impaired QoL in patients with acromegaly.

METHODS

We developed a Japanese version of the AcroQoL by a forward-backward method and evaluated QoL in 38 patients with acromegaly who had been followed up at an outpatient clinic at Kobe University Hospital. Its reliability was examined with Cronbach's alpha and item-total correlations. Second examination was performed for concurrent validity by assessment of correlations with the Short Form-36 (SF-36) and longitudinal analysis of the AcroQoL in 25 patients.

RESULTS

Cronbach's alpha and item-total correlations showed a range of 0.76-0.93 and 0.20-0.84, respectively, and significant correlations were found between the AcroQoL and the SF-36. Younger age and a history of radiotherapy were associated with worse total score by the multivariate linear regression analysis (p = 0.020 and p = 0.042, respectively). Intriguingly, in the biochemically-controlled group after the exclusion of patients who received radiotherapy, patients who underwent surgery alone exhibited a higher psychological (75.0 vs. 65.7 %, p = 0.036) and appearance (64.3 vs. 53.6 %, p = 0.036) score than those who are treating with pharmaceutical therapy.

CONCLUSIONS

The reliability of the Japanese version of the AcroQoL was satisfactory. Younger age and a history of radiotherapy were associated with lower QoL in patients with acromegaly. In biochemically-controlled acromegaly, patients who underwent surgery alone exhibited better QoL than those under pharmaceutical therapy.

Disease control and treatment modalities have impact on quality of life in acromegaly evaluated by Acromegaly Quality of Life (AcroQoL) Questionnaire

Various factors influence quality of life (QoL) in acromegaly. Whether disease control and treatment approach are related to QoL is still a matter of debate. The aim of the present study was to evaluate QoL in patients with acromegaly using the disease-specific Acromegaly Quality of Life Questionnaire in respect to disease activity, treatment modalities, and other factors. We studied 212 patients with acromegaly in a cross-sectional manner over a 6-year period in a single tertiary center. As a second step, seventy of the patients who were with active disease at baseline were followed up prospectively and 45 of them were in remission at re-evaluation. In regard to the cross-sectional group, active acromegaly independently predicted worse appearance scores. Prior radiotherapy and older age were independent negative predictors of all scales. Female gender negatively predicted all scales except the appearance domain. Longer duration of remission predicted worse personal relations scores in biochemically controlled patients. The use of somatostatin analog (SSA) was associated with worse personal relations scores, while higher IGF-1 index predicted worse appearance scores in patients with active acromegaly. In the prospective group, achievement of remission independently predicted improvement of the total scale. Lower corresponding baseline scores predicted improvement of the total, physical, and appearance scales, while the absence of hypopituitarism independently predicted improvement of the appearance scale. The use of SSA was associated with improvement of the total and appearance scores. In conclusion, QoL is a multifactorial issue that needs an individualized approach for detection and management.

Acromegaly and aging: a comparative cross-sectional study

OBJECTIVE

Cognitive and functional geriatric assessment may change in acromegaly. Herein we aimed to determine at which points geriatric assessment of the cases with acromegaly differs from that of general elderly population.

DESIGN

In this comparative cross-sectional study, a total of 30 cases with acromegaly (controlled n = 14, uncontrolled n = 16) and 30 gender and body-mass index-matched cases without acromegaly (control group, CG) above 60 years old were included. Cognitive functions were evaluated on the basis of the mini-mental state exam (MMSE). Affective status was determined using the geriatric depression scale. Activities of daily living (ADL) were ranked according to the Barthel index while instrumental activities of daily living (IADL) were graded on the basis of the Lawton scale. Nutritional status was evaluated using the mini-nutritional assessment (MNA). Body composition was measured through bioimpedance analysis. Functional mobility was determined using the Timed Up and Go test (TUG) and muscle strength with the handgrip strength test.

RESULTS

Scores on the MMSE were significantly lower in the elderly cases with acromegaly than in the cases without acromegaly (p < 0.001). Dementia was more frequent in the acromegaly group than in the CG (p = 0.04). Total MNA scores were significantly lower in cases with acromegaly than in the CG (p = 0.006). More subjects in the acromegaly group (33%) were at greater risk of malnutrition than in the CG (3%) (p = 0.003). There was greater moderate functional impairment based on Barthel ADL in the acromegaly group than in the CG (p = 0.04).

CONCLUSION

Acromegaly may impair cognitive functions, functional mobility and instrumental daily living activities in the geriatric population. With acromegaly, the risk of malnutrition may also increase.

Growth hormone deficiency in treated acromegaly

Growth hormone deficiency (GHD) of the adult is characterized by reduced quality of life (QoL) and physical fitness, skeletal fragility, and increased weight and cardiovascular risk. Hypopituitarism may develop in patients after definitive treatment of acromegaly, but an exact prevalence of GHD in this population is still uncertain owing to limited awareness and the scarce and conflicting data available on this topic. Because acromegaly and GHD may yield adverse consequences on similar target systems, the final outcomes of some complications of acromegaly may be further affected by the occurrence of GHD. However, it is still largely unknown whether patients with post-acromegaly GHD may benefit from GH replacement. We review the diagnostic, clinical, and therapeutic aspects of GHD in adult patients treated for acromegaly.

Health Outcomes in Acromegaly: Depression and Anxiety are Promising Targets for Improving Reduced Quality of Life

INTRODUCTION

Remission criteria of acromegaly are based on biochemical variables, i.e., normalization of increased hormone levels. However, the established reduction in Quality of Life (QoL) is suggested to be independent of biochemical control. The aim of this study was to test which aspects predict QoL best in acromegaly.

METHODS/DESIGN

This is a prospective cohort study in 80 acromegalic patients, with a cross-sectional and longitudinal part. The main outcome measure was health-related QoL, measured by a generic and a disease-specific questionnaire (the SF-36 and AcroQoL). Main predictors were age, gender, biochemical control, disease characteristics, treatment modalities, and psychopathology.

RESULTS

Our cohort of 80 acromegalics had a mean age 54.7 ± 12.3 years with an average disease duration of 10.8 ± 10.0 years. Ratio macro-/microadenoma was 54/26. In adjusted mixed method models, we found that psychopathology significantly predicts QoL in acromegaly (in models including the variables age, gender, disease duration, tumor size, basal hormone levels, relevant treatment modalities, and relevant comorbidities), with a higher degree of psychopathology indicating a lower QoL (depression vs. AcroQoL: B = -1.175, p < 0.001, depression vs. SF-36: B = -1.648, p < 0.001, anxiety vs. AcroQoL: B = -0.399, p < 0.001, anxiety vs. SF-36: B = -0.661, p < 0.001). The explained variances demonstrate superiority of psychopathology over biochemical control and other variables in predicting QoL in our models.

DISCUSSION

Superiority of psychopathology over biochemical control calls for a more extensive approach regarding diagnosing depression and anxiety in pituitary adenomas to improve QoL. Depressive symptoms and anxiety are modifiable factors that might provide valuable targets for possible future treatment interventions.
