Introduction: The aim of this study was to analyze psychological factors of patients with acromegaly and assessment of their relationship with the quality of life (QoL) in the context of the control of the disease. Materials and methods: A total sample of 50 patients (62% of females; mean age = 51.66 ± 14.5) with acromegaly underwent a comparative, cross-sectional cohort assessment including the QoL (AcroQoL, WHOQoL-BREF), psychiatric morbidity (GHQ-28), the acceptance of illness (AIS) as well as influence of treatment, comorbidities and symptoms in the relation of disease activity. Acromegaly group was divided in two subgroups: patients with uncontrolled acromegaly (UA, n = 28) and patients with controlled acromegaly (CA, n = 22). Results: The acromegaly groups did not differ in health-related QoL measured with AcroQoL and WHOQoL questionnaires. However, obtained results showed QoL impairments in all subscales and the study participants had decreased scores compared to reference values. The interaction of the relationship between the AIS and disease activity as well as the prevalence of all psychopathological symptoms and disease activity were tested and the statistically significantly differences in the context of QoL in AcroQoL questionnaires and its domains were observed in relation to the course of the disease. No difference in acromegaly symptoms as well as in number of comorbidities were found between CA and UA but these two parameters affected the results QoL scores in AcroQol questionnaires and their domains, regardless the disease activity. Similarly, the prevalence of psychopathological symptoms (GHQ-28) contributed the level of acceptance of the disease, regardless the disease activity. The strongest predictors of QoL were related to the level of illness acceptance (p = 0.01) as well as serum growth hormone concentration. Conclusion: Minding people with UA, the control of biochemical factors seemed to be more important for the QoL perception, while among CA, psychological variables such as AIS are observed to play a fundamental role in QoL. Moreover, inclusion of patient's acceptance of the illness into clinical routine would promote holistic, patient-centered care and empower doctor-patient partnership where patients' expectations and perceptions are constantly tracked. Obtaining biochemical control should not be considered as the only measure of treatment success.

Introduction: The vitamin D receptor (VDR) gene is one of the most widely studied tumorigenesis-related genes. The primary objective of this study was assessment of possible roles of VDR gene polymorphisms in acromegaly, with regard to the activity of the disease and compared them with a control group. Furthermore, we have assessed the associations between these polymorphisms with vitamin D status as well as with TBS (trabecular bone score) and risk for osteoporotic fracture in acromegaly patients. Materials and Methods: We studied 69 patients with acromegaly and 51 healthy controls (CG). Acromegaly patients were divided into three subgroups on the basis of disease activity (AA, active acromegaly; CD, controlled disease; CA, cured acromegaly). In all patients, blood samples were obtained to assess the hormonal and metabolic status as well as genetic analysis. VDR polymorphisms were determined by means of two methods, Polymerase Chain Reactions (PCR) and minisequencing (SNaPshot). Results: Genotype frequencies for VDR ApaI, TaqI, BsmI, and FokI polymorphisms did not deviate significantly from Hardy-Weinberg equilibrium (HWE) in the acromegaly group as well as in the control group. There was no statistically significant difference in distributions of these four VDR genotypes between acromegaly patients and the control group. This study revealed statistically significant negative correlation between risk of major osteoporotic fractures and genotypes tt (TaqI), aa (ApaI) and bb (BsmI) in acromegaly groups. Furthermore, the negative correlations were observed between TBS and risk for major osteoporotic fractures and hip fractures. Conclusions: Our study suggests that tt (TaqI), aa (ApaI) and bb (BsmI) of VDR gene may be associated with better bone quality and microarchitecture (higher TBS), which lead to a lower risk of osteoporotic fractures in acromegaly patients. TBS may be a useful tool for predicting risk of fractures in acromegaly patients.
