Acromegaly is a rare disorder caused by chronic growth hormone (GH) hypersecretion. While diagnostic and therapeutic methods have advanced, little information exists on trends in acromegaly ...characteristics over time. The
, a relational database, is designed to assess the profile of acromegaly patients at diagnosis and during long-term follow-up at multiple treatment centers. The following results were obtained at diagnosis. The study population consisted of 3173 acromegaly patients from ten countries; 54.5% were female. Males were significantly younger at diagnosis than females (43.5 vs 46.4 years;
< 0.001). The median delay from first symptoms to diagnosis was 2 years longer in females (
= 0.015). Ages at diagnosis and first symptoms increased significantly over time (
< 0.001). Tumors were larger in males than females (
< 0.001); tumor size and invasion were inversely related to patient age (
< 0.001). Random GH at diagnosis correlated with nadir GH levels during OGTT (
< 0.001). GH was inversely related to age in both sexes (
< 0.001). Diabetes mellitus was present in 27.5%, hypertension in 28.8%, sleep apnea syndrome in 25.5% and cardiac hypertrophy in 15.5%. Serious cardiovascular outcomes like stroke, heart failure and myocardial infarction were present in <5% at diagnosis. Erythrocyte levels were increased and correlated with IGF-1 values. Thyroid nodules were frequent (34.0%); 820 patients had colonoscopy at diagnosis and 13% had polyps. Osteoporosis was present at diagnosis in 12.3% and 0.6-4.4% had experienced a fracture. In conclusion, this study of >3100 patients is the largest international acromegaly database and shows clinically relevant trends in the characteristics of acromegaly at diagnosis.
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.
There is evidence in the literature that hypofunction of the thyroid gland (hypothyroidism) affects color vision in rodents by influencing the production of the visual pigment opsin. The effect of ...hypothyroidism on color vision in humans has not been examined in any great detail. In this cross-sectional study we evaluated color discrimination using the Farnsworth-Munsell 100 hue test (FM-100 test) in 25 individuals with pre-treatment hypothyroidism (mean age ${38}\;{\pm }\;{9}.{2}\;\text{yr}$38±9.2yr), and a control euthyroid group, ${ n} ={26}$n=26 (mean age ${39.6}\;{\pm }\;{8}.{4}\;\text{yr}$39.6±8.4yr). There was no statistically significant difference in the total error score ($\surd{\text{TES}}$√TES) between the groups, but the hypothyroid group had a significantly greater partial error score ($\surd{\text{PES}}$√PES) along the blue-yellow (B-Y) axis compared to the red-green (R-G) axis. No statistically significant differences in B-Y and R-G PES were observed in the control group. This study shows that hypothyroidism affects color vision in humans, causing significant impairment in the B-Y color subsystem.
Our previous study has shown that individuals with untreated hypothyroidism display significantly higher partial error scores (
) along the blue-yellow axis compared to the red-green axis than normal ...individuals using the Farnsworth-Munsell 100 hue test J. Opt. Soc. Am. A37, A18 (2020)JOAOD60740-323210.1364/JOSAA.382390. We wished to determine how color discrimination may change when hypothyroidism has been treated to the point of euthyroidism. Color discrimination was reassessed for 17 female individuals who had undergone treatment for hypothyroidism, and the results were compared with 22 female individuals without thyroid dysfunction. No statistically significant difference was found in the total error score (
) for the first and second measurements for both groups (
>0.45). The
for the hypothyroid group improved significantly in the previously impaired color regions after the treatment. Color discrimination defects found in untreated hypothyroidism can be negated with treatment of the condition over an appropriate time period.
Background
The potent immunomodulatory action of prolactin has been demonstrated in many experimental in vitro studies. In accordance with these data, our retrospective analyses revealed higher ...prevalence of autoimmune thyroid diseases in prolactinoma patients compared to general population.
Purpose
A cross-sectional case-control study was carried out in a single tertiary referral centre. The main aim was to assess the frequency of newly diagnosed autoimmune thyroid diseases in female patients with prolactinomas.
Methods
The study population consisted of 260 females (154 patients and 106 sex-matched, ethnicity-matched, and age-matched healthy controls) enroled in a prospective manner. Physical exam, thyroid ultrasound, and laboratory testing (measurement of antibodies to thyroglobulin, thyroid peroxidase, TSH-receptor, serum TSH and FT4 levels) were performed in all study participants.
Results
Autoimmune thyroid diseases were diagnosed in 29.9% of the patients and 10.4% of the healthy subjects (
p
= 0.0002). Subclinical hypothyroidism was found in 9.7% of the patients versus 2.8% of the controls (
p
= 0.044). Autoimmune hyperthyroidism was observed in 1.3% of all patients.
Conclusions
The prevalence of newly diagnosed autoimmune thyroid diseases, and especially the subclinical hypothyroidism, was significantly higher in our female prolactinoma patients in comparison to age-matched healthy women. Based on our results, we suggest routine screening for autoimmune thyroid diseases (thyroid function, immunology and ultrasound examination) in all female patients with prolactinoma at the time of diagnosis. We also recommend a close follow-up of thyroid function in these women in case of pregnancy and after delivery.
Cardiomyopathy is the most frequent cardiovascular complication in acromegaly.
We aimed to compare some echocardiographic markers in acromegaly patients with controls and find a correlation with ...disease duration, disease activity, levels of growth hormone (GH) and insulin-like growth factor 1 (IGF-1).
We conducted a cross-sectional case-control study for the period of 2008-2012.
Acromegaly patients altogether 146 (56 men and 90 women), were divided into four groups according to disease activity and the presence of arterial hypertension (AH). The control group included 83 subjects, matching the patient groups by age, gender and presence of AH. GH was measured by an immunofluorometric method, while IGF-1 by IRMA method. All patients and controls were subjected to one- and two-dimensional transthoracic echocardiography, color and pulse Doppler.
We found a thickening of the left ventricular walls and an increase in the left ventricular mass. However, these changes were not statistically significant in all groups and no correlation with disease duration could be demonstrated. As markers of diastolic dysfunction, increased deceleration time and isovolumetric relaxation were registered, which were dependent mainly on age in a binary logistic regression analysis, but not GH or IGF-1. Using absolute values, ejection and shortening fractions were increased in some groups. Using cut-off values, a higher percentage of systolic dysfunction was demonstrated in patients compared to their corresponding controls. Engagement of the right heart ventricle was also found - increased deceleration time and decreased e/a tric ratio.
In conclusion, functional impairments of both ventricles were present, with a predominance of left ventricular diastolic dysfunction.
Adult growth hormone deficiency (AGHD) is a rare disease characterised by abnormal body composition, reduced strength and exercise capacity and impaired psychological wellbeing. An advisory board of ...leading Central and Eastern European (CEE) endocrinologists was assembled to gain insights into the status of AGHD care in the CEE region. Topics of discussion included the position of adult hypopituitarism/AGHD in health system priorities, availability and affordability of treatments, awareness of AGHD, practice guidelines used in CEE countries and provisions for long-term care of patients.
Prior to the meeting, the advisors were asked to summarise, using an itemised survey questionnaire, the usual standards of care for patients with AGHD in their country. At the meeting, the panel of experts discussed the findings and thereby elucidated similarities and differences among CEE countries; these were compared with international guideline-recommended practices for AGHD.
All CEE countries involved reported having some type of infrastructure in place for care of patients with GHD transitioning from adolescence to adulthood. Most countries reported having at least one specialist centre for patients with AGHD. The main variations across the region included initial entry into healthcare systems, tests required to confirm AGHD diagnosis and medication reimbursement by health authorities. Most CEE countries relied on international society-led guidelines, while some countries have developed national guidelines.
The CEE Adult Endocrinology Advisory Board meeting recognised considerable diversity in the care and patient pathways for AGHD across CEE countries. Additional work is needed to optimise care of patients with AGHD in the CEE region.
•Management of adult growth hormone deficiency varies across Central & Eastern Europe.•Variations in local treatment practices, diagnostic assessments and reimbursement.•Recommendations for patient referral, evaluation and management are provided.•Education on AGHD for healthcare providers and patients would be beneficial.
