RESUMO
OBJECTIVES: This study aims to estimate the impact of disease activity, obesity, functional disability, and depression on lipid status, glycoregulation, and risk for coronary heart disease (CHD) in patients with rheumatoid arthritis (RA). PATIENTS AND METHODS: A total of 36 patients with RA (30 women and 6 men, mean age 54.9 years, mean disease duration 7.9 years) were included in this study. We estimated the impact of age, body mass index, disease activity [assessed by DAS28 index and C-reactive protein (CRP) value], functional ability (estimated using the HAQ disability index), and depression [assessed using the Beck Depression Inventory (BDI)] on glycoregulation, lipid status, and risk for CHD in our patients. Glycoregulation was assessed by measuring insulin resistance, insulin, and glucose in blood. Lipids tested in blood included total cholesterol, HDL and LDL cholesterol, and triglycerides (TG). The 10-year risk for CHD was estimated using the Framingham risk score. RESULTS: Of 36 patients, 11 (30.6 %) fulfilled the criteria for metabolic syndrome (MS). Ten of 11 patients (90.1 %) with MS have a 10-year risk for CHD greater than 10 % compared to only 3 of 25 patients (12 %) without MS (p = 0.0001). Patients with high disease activity had lower HDL values than patients with mild or moderate disease activity (1.4 vs. 1.7 mmol/l, p = 0.04). Significant correlations were observed between CRP level and insulinemia (ρ = 0.57, p = 0.003), as well as CRP level and the HOMA index (ρ = 0.59, p = 0.002). The body mass index (BMI) correlated significantly with total cholesterol (r = 0.46, p = 0.02), LDL (ρ = 0.41, p = 0.04), and TG (ρ = 0.65, p < 0.001) in blood. The HAQ-DI did not correlate either with parameters of glycoregulation or lipid status. There was a significant positive correlation between BDI and BMI (ρ = 0.60, p < 0.001). CONCULSION: Active RA is independently associated with decreased HDL cholesterol and increased insulin resistance. Obesity was found to be an independent risk factor for increased total cholesterol, LDL cholesterol, and TG. Depressed patients with RA tend to be overweight or obese and, therefore, have an unfavorable lipid profile.

AIM: We sought to study the effect of tubal ligation on lipid profile, ovarian reserve and hot flashes during perimenopausal years. METHODS: A total of 210 perimenopausal women complaining of abnormal vaginal bleeding were enrolled for the study. Subjects' menstrual, reproductive and medical histories were recorded. Serum FSH, LH and estradiol levels were screened in all women to determine menopausal status. In order to rule out any gynecologic pathology, all subjects underwent transvaginal sonography. Women were divided into two groups according to presence (study group, n = 68) or absence (control group, n = 142) of tubal ligation history. Lipid profiles and ovarian reserve tests were compared between groups. RESULTS: Mean age, parity, serum hemoglobin (Hb), high density lipoprotein (HDL-C), triglyceride, estradiol levels, endometrial thickness and frequency of hot flashes were significantly different between groups (p < 0.05). Mean age was 42.8 ± 1.9 years in women with tubal ligation and 45.9 ± 3.5 years in control group. Mean serum estradiol level was lower in group with tubal ligation (41.4 versus 92.5 pg/ml). Mean endometrial thickness was higher in control group (10.2 versus 7.5 mm). Age-adjusted serum Hb, HDL-C, triglyceride, estradiol, FSH level, endometrial thickness and frequency of hot flashes remained significantly different between groups (p < 0.05). CONCLUSION: Tubal ligation is associated with unfavorable lipid profile and higher frequency of hot flashes during perimenopausal years.

Xanthomas are visibly deformed cholesterol deposits that are commonly associated with lipid disorders, such as familial hypercholesterolemia (FH) or rare sitosterolemia. We present the first report of two cases of carotid sheath xanthomas in patients with lipid disorders. Case 1 involved a 26-year-old woman presenting with two heterogeneous mutations on the ABCG5 gene-as noted on genetic testing-who was finally diagnosed with sitosterolemia. Ultrasonography (US) revealed hypoechoic masses centered in the bilateral carotid sheath, which gradually reduced in size after diet control and the use of ezetimibe. Case 2 involved a 27-year-old man who was diagnosed with possible FH and had recurrent bilateral buttock xanthomas, as well as bilateral carotid sheath masses detected by US. Postoperative pathological examination of the resected right neck mass confirmed a xanthoma with proliferation of multinucleated giant cells and deposition of cholesterol clefts.

BACKGROUND: Lipoedema is an accumulation of fat abnormally distributed in the lower limbs, and lymphoedema is oedema caused by a deficiency of the lymphatic system. High-resolution ultrasound operating at 20 MHz makes it possible to characterize dermal oedema. OBJECTIVES: The purpose of our study was to demonstrate that high-resolution ultrasound imaging of the skin can differentiate lipoedema from lymphoedema. METHODS: Sixteen patients with lymphoedema (22 legs), eight patients with lipoedema (16 legs) and eight controls (16 legs) were included. Patients with lipolymphoedema were excluded. Ultrasound examinations were carried out with a real-time high-resolution ultrasound device on three different sites for each lower limb. The images were then anonymized and examined by an independent dermatologist who was blind to the clinical diagnosis. A new series of images was examined by three dermatologists to check interobserver agreement. RESULTS: A significant difference in dermal thickness was observed between patients with lymphoedema and those with lipoedema and between patients with lymphoedema and controls. No significant difference in dermal thickness was shown between patients with lipoedema and controls at the thigh or ankle. Dermal hypo-echogenicity was found in at least one of the three sites in 100% of patients with lymphoedema, 12.5% of cases with lipoedema and 6.25% of the controls. Hypoechogenicity affected the entire dermis in all cases of lymphoedema except one. In cases of lipoedema and controls, hypoechogenicity was localized at the ankle and prevailed in the upper dermis. The expert correctly diagnosed all lower limbs with lymphoedema. No cases of lipoedema were diagnosed as lymphoedema. Exact interobserver agreement was excellent (0.98). CONCLUSIONS: High-resolution cutaneous ultrasonography makes it possible to differentiate lymphoedema from lipoedema. Obtaining a reliable diagnosis through high-resolution cutaneous ultrasonography might be valuable for improving the treatment of lipoedema and lymphoedema.

CONTEXT: Metabolic disorders, especially dysregulated lipid metabolism, increase the risk of cardiovascular mortality in acromegaly. Previous studies measuring plasma macromolecular lipids have yielded conflicting results. PURPOSE: To explore the plasma lipid metabolite profiles by metabolomics analysis and identify potential metabolites associated with cardiac function in acromegaly. METHODS: Plasma was obtained from 80 newly diagnosed, untreated patients with acromegaly and 80 healthy controls. Echocardiography was performed. Based on the results of an oral glucose tolerance test (OGTT), patients were categorized into 2 groups: normal glucose tolerance (NGT, nâ =â 28) and impaired glucose tolerance or diabetes mellitus (IGT/DM, nâ =â 52). High-performance liquid chromatography-mass spectrometry (HPLC-MS)-based metabolomics analysis was conducted. Data were processed by principal components analysis (PCA), orthogonal partial least square-discriminant analysis (OPLS-DA), and MetaboAnalyst 4.0. Associations between metabolic substances and cardiovascular parameters were also explored. RESULTS: Metabolomics uncovered a distinct metabolic pattern between acromegaly and healthy controls, and perturbed pathways mainly include glycerophospholipid metabolism, sphingolipid metabolism, as well as linoleic acid metabolism. Collective analysis showed that phosphatidylethanolamine (PE) (22:6/16:0) was positively correlated with LV mass, while lysophosphatidylcholine (LysoPC) (16:0) was positively correlated with fractional shortening (FS) and left ventricle ejection fraction (LVEF). CONCLUSION: Patients with acromegaly have distinct lipid metabolite profiling, while PE (22:6/16:0) and LysoPC (16:0) are correlated with cardiac structure and function, which may contribute to the risk of cardiovascular complications.

BACKGROUND: Cardiovascular diseases are one of the most common causes of the prevalence and mortality in the general population. Progressing pollution of the environment, as well as occupational exposure to heavy metals, including lead, may potentially accelerate the development of these disorders. Lead is a well known risk factor of arterial hypertension, and may be involved in atherogenesis. The aim of this study was to assess the influence of occupational lead exposure on the activity of cardiovascular system (CVS). MATERIAL AND METHODS: The study group comprised 153 potentially healthy volunteers, working in a crystal glass foundry. They were examined using ultrasound assessment of carotid arteries, electrocardiograms and ankle-brachial index (ABI). The toxicological assessment of the study group for occupational lead poisoning was performed. Correlations between the degree of intoxication and functional changes in CVS were analyzed. RESULTS: A negative linear correlation between blood lead level or fluorethylenepropylene (FEP) concentration and ABI values was shown, but only in a subgroup with normal lipid pattern. In the persons with higher blood lead levels, the higher values of arterial blood pressure and longer QT-space in electrocardiogram were evidenced. In addition, the right bundle branch block was more frequently observed (in 23% of workers). CONCLUSIONS: Lead may be an independent risk factor of cardiovascular diseases, especially in workers with normal lipid parameters. An increased arterial blood pressure and a decreased ankle-brachial index in the persons with normal cholesterol level can be regarded as a marker of this risk.

BACKGROUND/AIMS: Pancreatic steatosis (PS) is a generally used term to define accumulation of fat in the pancreas. In theory PS may be able to affect the exocrine function of pancreas. In this study we aimed to determine the effect of PS on exocrine pancreas function. MATERIALS AND METHODS: Forty-three patients with PS determined by 3 tesla magnetic resonance imaging (MRI) and 48 patients without PS were included in this study. Patients with PS were classified as group 1 and control patients were classified as group 2. Fecal elastase-1 levels were determined. Fecal elastase-1 levels <200 µg/g were defined as exocrine pancreatic insufficiency (EPI). Patients with PS were further grouped according to severity and anatomic distribution of steatosis based on findings of 3 tesla MRI. RESULTS: Fecal elastase-1 levels was significantly lower in group 1 compared to group 2 (319.76±45.7 vs 549.31±69.4, respectively, p=0.003). Proportion of patients with EPI was significantly higher in group 1 than group 2 (35.5% vs 12% p=0.042). There were no significant differences in terms of severity or the anatomic distribution of PS in patients with PS with EPI based on MRI (p=0.052, p=0.198, p=0.405) Conclusion: Current study demonstrates that PS can cause EPI.

BACKGROUND: The clinical features of lipid infiltration in the parotid glands (LIPG) have not been studied. Monitoring of atomic-bomb survivors for late effects of radiation exposure has provided the opportunity to review the clinical findings of LIPG. METHODS: A total of 992 atomic-bomb survivors in Nagasaki, Japan underwent lachrymal and salivary secretion tests and anthropometric, biochemical, and abdominal ultrasonographic examinations between 2002 and 2004. Among 465 subjects who had reduced tear and/or salivary excretion, 176 subjects took a salivary magnetic resonance imaging (MRI) examination. RESULTS: LIPG was detected in 53 of the 176 subjects who had salivary MRI. LIPG cases showed a preponderance of females and fatty liver compared with the subjects without LIPG. Age-and-sex-adjusted regression analysis revealed that body mass index (BMI), low-density lipoprotein cholesterol, triglycerides, hemoglobin A1c, and C-reactive protein were higher, whereas high-density lipoprotein cholesterol and adiponectin were lower, in the subjects with LIPG. Multivariate logistic regression analysis showed that BMI and fatty liver were mutually associated with LIPG independently from radiation dose. CONCLUSIONS: LIPG associated with BMI, fatty liver, and coronary risk factors was a clinical manifestation of metabolic syndrome.
