ABSTRACT

The major causes of both morbidity and mortality in patients with acromegaly are cardiovascular diseases (CVDs). The polymorphisms of the fat mass and obesity-associated gene (FTO) are associated with obesity, as well as with an increased risk of CVDs. The aim of the study was to determine the relationship of risk alleles of four FTO gene polymorphisms with selected parameters of lipid and glucose metabolism as well as with IGF-1 and GH levels in the group of patients with acromegaly compared to the control group. The study group consisted of 104 patients with acromegaly and 64 healthy subjects constituting the control group. In the whole acromegaly group, the data reveal that the homozygous for risk allele carriers (rs1421085, rs9930506, rs9939609) as well as carriers of only one risk allele have lower IGF-1 concentrations. In the well-controlled acromegaly group, the homozygous for three risk allele carriers of FTO gene polymorphisms have lower HDL cholesterol concentration (rs1121980, rs1421085, rs993609). In the cured acromegaly group, homozygous risk allele carriers rs9930506 tend to have higher levels of total cholesterol and LDL cholesterol. These associations are not observed in the control group. Conclusion: there is an association between FTO gene polymorphisms and the metabolism of lipids, suggesting that the FTO gene may be associated with higher CVD risk in patients with acromegaly. In addition, there is an association between FTO gene polymorphisms and IGF-1, implying that FTO gene may influence/modify IGF-1 synthesis. Further investigation on a larger scale is required to provide more precise evidence.

ABSTRACT

Acromegaly is a rare endocrine disorder caused by somatotroph pituitary adenoma. Besides its typical symptoms, it contributes to the development of cardiovascular, metabolic, and bone comorbidities. H19 RNA is a long non-coding RNA and it is suspected to be involved in tumorigenesis, cancer progression, and metastasis. H19 RNA is a novel biomarker for the diagnosis and monitoring of neoplasms. Moreover, there might be an association between H19 and cardiovascular and metabolic diseases. We enrolled 32 acromegaly patients and 25 controls. We investigated whether whole blood H19 RNA expression is associated with the diagnosis of acromegaly. Correlations between H19 and tumour dimension, invasiveness, and biochemical and hormonal parameters were evaluated. We analysed the coincidence of acromegaly comorbidities with H19 RNA expression. In the results, we did not observe a statistically significant difference in H19 RNA expression between acromegaly patients and the controls. There were no correlations between H19 and the adenoma size and infiltration and patients' biochemical and hormonal statuses. In the acromegaly group, hypertension, goitre, and cholelithiasis were observed more frequently. The diagnosis of acromegaly was a factor contributing to the occurrence of dyslipidaemia, goitre, and cholelithiasis. We found an association between H19 and cholelithiasis in acromegaly patients. To conclude, H19 RNA expression is not a relevant marker for diagnosis and monitoring of acromegaly patients. There is a higher risk of hypertension, goitre, and cholelithiasis related to acromegaly. Cholelithiasis is associated with a higher H19 RNA expression.

ABSTRACT

Introduction: In acromegaly, chronic exposure to impaired GH and IGF-I levels leads to the development of typical acromegaly symptoms, and multiple systemic complications as cardiovascular, metabolic, respiratory, endocrine, and bone disorders. Acromegaly comorbidities contribute to decreased life quality and premature mortality. The aim of our study was to assess the frequency of acromegaly complications and to evaluate diagnostic methods performed toward recognition of them. Materials and Methods: It was a retrospective study and we analyzed data of 179 patients hospitalized in the Department of Endocrinology, Diabetes and Isotope Therapy in Wroclaw Medical University (Poland) in 1976 to 2018 to create a database for statistical analysis. Results: The study group comprised of 119 women (66%) and 60 men (34%). The median age of acromegaly diagnosis was 50.5 years old for women (age range 20-78) and 46 for men (range 24-76). Metabolic disorders (hyperlipidemia, diabetes, and prediabetes) were the most frequently diagnosed complications in our study, followed by cardiovascular diseases and endocrine disorders (goiter, pituitary insufficiency, osteoporosis). BP measurement, ECG, lipid profile, fasting glucose or OGTT were performed the most often, while colonoscopy and echocardiogram were the least frequent. Conclusions: In our population we observed female predominance. We revealed a decrease in the number of patients with active acromegaly and an increase in the number of well-controlled patients. More than 50% of patients demonstrated a coexistence of cardiac, metabolic and endocrine disturbances and only 5% of patients did not suffer from any disease from those main groups.

ABSTRACT

Long non-coding RNAs (lncRNAs) are over 200 nucleotides long recently discovered RNA molecules that are not involved in the translation process. Accumulating evidence shows that H19 lncRNA is an important regulator of gene expression and its altered expression contributes to carcinogenesis. The aim of this review was to reveal current knowledge about H19 lncRNA and its impact on tumours of the endocrine system. We present findings about H19 altered regulation and its association with tumorigenesis, cancer progression and differentiation, and its potential use in diagnostics, prognostics and therapy. The mechanism and molecular pathways involved in these processes are discussed.

ABSTRACT

INTRODUCTION: Radiofrequency echographic multi-spectrometry (REMS) is a recently introduced non-ionising technology employed in the evaluation of osteoporosis. The aim of our study was to compare bone mineral density (BMD) in acromegaly patients and healthy controls by performing novel REMS densitometry. The second objective was to analyse the correlation between results of REMS and classical dual-energy X-ray absorptiometry (DXA) in acromegaly patients. MATERIAL AND METHODS: We enrolled 33 patients with acromegaly (AG) and 24 controls (CG). The acromegaly patients were divided into two subgroups: well-controlled acromegaly (WCA) and surgery-cured acromegaly (SCA). REMS was performed in all participants, while DXA was performed only in the acromegaly group. IGF-I and GH levels were measured in acromegaly patients. RESULTS: Bone mineral density of the lumbar spine (LS) and the femoral neck (FN) obtained from REMS did not reveal significant differences between AG, CG, WCA, and SCA. Similarly, there were no significant differences in BMD measured by DXA at the LS and at the FN between WCA and SCA. Significant positive correlations between IGF-I concentrations and BMD obtained from both REMS and DXA were detected in the AG and WCA. In the AG and WCA, there were positive correlations between T-scores and LS BMD obtained from both methods. CONCLUSIONS: Radiofrequency echographic multi-spectrometry is a potential method in assessment of bone status in acromegaly. Further studies with participation of active disease patients are needed.
