RESUMO

OBJECTIVES: This nationwide, multicentric, retrospective analysis of 1,126,946 COVID-19 cases (March 2020-June 2022) aims to elucidate the impact of COVID-19 vaccination on mortality in patients with a sole solid malignancy. METHODS: Using data from the national digital medical record repository, outcomes were compared among fully vaccinated and nonvaccinated cohorts, factoring in gender, virus type, age, vaccination status, vaccine type, and cancer type. Logistic regression calculated odds ratios (OR) and their significance. RESULTS: Among 6,050 patients with both cancer and comorbidities, 1,797 had only solid malignancy. Vaccinated individuals in this group had reduced mortality rates, especially those >63 years (OR 0.169 [95% confidence interval [CI] 0.090-0.317]; P < .001). Lower deaths were observed in non-ICU (OR 0.193 [95% CI 0.097-0.382]; P < .001) and ICU cases (OR 0.224 [95% CI 0.077-0.646]; P = .003), with both vaccine types. No statistically significant benefits were observed against delta and omicron variants. Intrathoracic malignancies (OR 0.376 [95% CI 0.146-0.971]; P = .043) and palliative treatment (OR 0.384 [95% CI 0.192-0.766]; P = .006) showed vaccination benefits. Logistic regression revealed a higher fatal risk in nonvaccinated males >63. Propensity score matching supported these outcomes. CONCLUSIONS: Patients with sole solid malignancies face elevated COVID-19 mortality risk, particularly without active cytostatic therapy, with advanced disease on palliative treatment, or intrathoracic malignancies.

RESUMO

BACKGROUND: The beneficial effects of application of a fixed dose beclomethasone dipropionate (BDP) and formoterol fumarate (F) for the treatment of severe chronic obstructive disease (COPD) has been amply proven in well controlled clinical trials. Whether this also holds for real-world conditions and in such a heterogeneous patient population as is encountered in Bulgaria remained to be investigated. METHODS: In an observational, non-interventional study, 441 Bulgarian patients with severe COPD who were enrolled at 36 sites across the country received extrafine BDP/FF-combination therapy using the NEXThaler® DPI or the Foster® pMDI over a period of 16 weeks. At visits at the beginning, after 4 weeks and at the end of the study, alterations in lung function parameters FEV1 and FVC, disease symptoms, changes in CAT score, and patient distribution in GOLD 2017 categories A through D were assessed. RESULTS: A large share of the Bulgarian patients with severe COPD suffered from serious comorbidities, received additional medication, and about 2/3 were former or current smokers. Extrafine BDP/FF caused an increase in mean FEV1, FVC, a decrease of health impact as assessed by the CAT score, and a considerable shift of the share of category C and D patients towards A and B. In addition, the percentage of patients that were free of symptoms impacting everyday life such as fatigue and shortness of breath at rest increased throughout the study. A comparison of both application devices indicated that the NEXThaler® was superior in terms of lung functional aspects, as these parameters displayed a constant improvement over the observation period, whereas they plateaued at week 4 when using the pMDI. CONCLUSIONS: The therapeutic benefits of extrafine BDP/FF known from clinical trials could also be observed in a real-world setting, even in such a heterogenous patient population as the Bulgarian. The NEXThaler® appeared to be highly efficient in this setting, opening a new choice for the lung specialist and the patient to select the one device considered most suitable and practical.

RESUMO

OBJECTIVE: Acromegaly is characterized by high neoplastic morbidity as a side effect of growth hormone (GH) hypersecretion. Increased incidence of goiter, thyroid carcinoma, and thyroid dysfunction is also reported. The aim of the present study was to find the prevalence of thyroid dysfunction and goiter in patients with acromegaly and determine its relationship to disease activity, disease duration, and the presence of secondary hypothyroidism. SUBJECTS AND METHODS: In a cross-sectional study of the period 2008-2012 were included 146 patients with acromegaly (56 men, 90 women) of mean age 50.3 ± 12.4 years. Acromegaly disease activity and thyroid function were evaluated in all patients. Thyroid ultrasonography was performed to calculate thyroid volume and detect the presence of nodular goiter. RESULTS: Ninety-one patients were determined to have an active disease, and 55, a controlled disease. The mean thyroid volume in patients without previous thyroid surgery was 37.6 ± 38.8 mL. According to disease activity, thyroid volume was significantly higher in patients with active disease (38.5 ± 45.4 mL vs. 27.2 ± 18.4 mL, p = 0.036). A weak positive correlation was found between thyroid volume and insulin-like growth factor 1 (IGF-1) in the whole group and in females (R = 0.218; p = 0.013, and R = 0.238; p = 0.037, respectively). There was no significant correlation of thyroid volume with disease duration and GH level in the whole group and in both sexes. The patients with secondary hypothyroidism had twofold smaller thyroid volume, relative to the rest of the group. The prevalence of thyroid dysfunction was 39%, with a female to male percentage ratio of 1.73. Goiter was diagnosed in 87% of patients, including diffuse goiter (17.1%) and nodular (69.9%), with no significant difference between patients with active and controlled disease or the presence of secondary hypothyroidism. CONCLUSIONS: Thyroid volume in patients with acromegaly depends on disease activity and the presence of secondary hypothyroidism as a complication. The increased prevalence of nodular goiter determines the need of regular ultrasound thyroid evaluation in the follow-up of patients with acromegaly. Arch Endocrinol Metab. 2020;64(3):269-75.

RESUMO

Cushing's syndrome (CS) is associated with serious comorbidities and an increased mortality rate that could be reduced only if strict biochemical control is achieved. The aim of this study was to show the 50-year experience of a single tertiary center in the management of CS patients - the different treatment modalities used over the years and the corresponding outcomes. It was a retrospective study of a large cohort of patients from the Bulgarian CS database: 613 patients (374 with ACTH-dependent and 239 with ACTH-independent CS). Pituitary surgery was applied to 242 patients with Cushing's disease (CD) with initial remission rate of 74% of which 10% relapsed. Approximately 36% manifested with active disease during the long-term follow-up (26% with persistent disease, 10% relapses) most of which were subjected to a secondary treatment (13.6% to pituitary resurgery, 14% to pituitary radiotherapy, and 5.4% to bilateral adrenalectomy). A total of 294 CD patients received medical therapy with overall remission rates for the most commonly used drugs: dopamine agonists 20%, pasireotide 30%, and ketoconazole 63%. Significant improvement of results was achieved by combining drugs with different mechanisms of action. Regardless of the progress in the neurosurgery and radiotherapy techniques and new drugs discovery, the management of patients with CS remains a real challenge for physicians. Not only patients with adrenal carcinoma but also significant percentage of subjects with persistent and recurrent Cushing's disease often require a polymodal approach and the efforts of a multidisciplinary highly qualified, experienced, and motivated team in order to achieve a long-term remission.

RESUMO

Apart from being individually associated with cardiometabolic health, 25(OH)D and IGF-1 interplay with a positive correlation between them, which raises questions about the role of vitamin D for the adverse cardiovascular (CV) risk profile in hyposomatotropism. Thus, we aimed to investigate vitamin D status in GH deficiency (GHD) and the association between 25(OH)D and metabolic syndrome (MetS), its components, and other surrogate markers of CV risk. A total of 129 GHD adults (childhood-onset GHD, 41.9%) underwent blood testing (glucose, insulin, lipid profile, uric acid); blood pressure, anthropometric and bioelectrical-impedance measurements. Other CV risk markers were examined in a subsample of the initial population - hsCRP, adiponectin, and asymmetric dimethylarginine (n=88); carotid intima-media thickness (n=44). Total serum 25(OH)D, measured by electro-chemiluminescence binding assay, was used for vitamin D status assessment (adequate,≥30 ng/ml; insufficient, 20-29.9 ng/ml; deficient,<20 ng/ml). Data demonstrated high prevalence of hypovitaminosis D in GHD (deficiency 79.1%; insufficiency 14.7%), with lower 25(OH)D among adult-onset GHD subjects (14.0±7.2 vs. 16.8±8.0 ng/ml, p=0.039) and patients with MetS (11.8±4.5 vs. 16.3±8.1 ng/ml, p<0.0001). 25(OH)D correlated negatively and weakly with BMI, waist circumference, percent body fat, visceral fat area, and systolic BP. Regardless of whether vitamin D is a cause or a consequence of these metabolic abnormalities, 25(OH)D testing in hyposomatotropism is advisable. Normalization of vitamin D status is not proven to improve CV outcomes in general population, but it might have favorable effects in GHD, as its benefits might be restricted to patients with both low 25(OH)D and certain risk factors.

RESUMO

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.

RESUMO

BACKGROUND: Mortality in acromegaly strictly depends on optimal control of GH and IGF1 levels. Modern medical therapy with somatostatin analogs (SSAs) and GH receptor antagonists (GHRAs) is not available in many countries due to funding restrictions. This retrospective, comparative, cohort study investigated the impact of different treatment modalities on disease control (GH and IGF1) and mortality in acromegaly patients. METHODS: Two cohorts of patients with acromegaly from Bulgaria (n=407) and Campania, Italy (n=220), were compared, and mortality rates were evaluated during a 10-year period (1999-2008). RESULTS: The major difference in treatment approach between cohorts was the higher utilization of SSAs and GHRAs in Italy, leading to a decreased requirement for radiotherapy. Significantly more Italian than Bulgarian patients had achieved disease control (50.1 vs 39.1%, P=0.005) at the last follow-up. Compared with the general population, the Bulgarian cohort had a decreased life expectancy with a standardized mortality ratio (SMR) of 2.0 (95% CI 1.54-2.47) that was restored to normal in patients with disease control - SMR 1.25 (95% CI 0.68-1.81). Irradiated patients had a higher cerebrovascular mortality - SMR 7.15 (95% CI 2.92-11.37). Internal analysis revealed an independent role of age at diagnosis and last GH value on all-cause mortality and radiotherapy on cerebrovascular mortality. Normal survival rates were observed in the Italian cohort: SMR 0.66 (95% CI 0.27-1.36). CONCLUSIONS: Suboptimal biochemical control was associated with a higher mortality in the Bulgarian cohort. Modern treatment options that induce a strict biochemical control and reduce the necessity of radiotherapy might influence the life expectancy. Other factors, possibly management of comorbidities, could contribute to survival rates.

RESUMO

UNLABELLED: Glucose metabolism disturbances are relatively common feature in pheochromocytoma patients. Decreased insulin secretion due to the inhibitory effect of supraphysiological plasma catecholamine concentrations was considered to be the main cause for pheochromocytoma-associated diabetes mellitus. However, data from animal and clinical studies have suggested that catecholamines can induce insulin resistance. More recent trials support the hypothesis that catecholamines inhibit adiponectin secretion. OBJECTIVE: The aim of the present study was to evaluate the relationship between adiponectin levels and insulin sensitivity in patients with endocrine hypertension due to pheochromocytoma comparing them to these in patients with essential hypertension and healthy subjects. DESIGN AND METHODS: Three groups of subjects were enrolled in the study: 26 patients with pheochromocytoma, 30 normal-weight patients with essential hypertension and 31 healthy subjects. Adiponectin levels were determined by radioimmunoassay (RIA). RESULTS: Serum adiponectin concentrations were significantly lower in patients with pheochromocytoma compared to these in normal-weight hypertensive patients and healthy controls. Postoperative adiponectin levels were significantly higher then preoperative despite of the increased BMI in pheochromocytoma patients. There was a significant negative correlation between adiponectin serum concentrations and preprandial glucose, insulin levels and HOMA as a marker of insulin sensitivity. In contrast to previous studies, we did not find a significant difference between circulating adiponectin levels in normal-weight patients with EH and healthy subjects. CONCLUSIONS: Hypoadiponectinemia in pheochromocytoma patients may represent a possible pathogenic factor for the development of carbohydrate metabolism disturbances in these patients.
