Background: Clinical studies have shown that sevelamer hydrochloride improves lipid profiles and attenuates the progression of the cardiovascular calcifications in haemodialysis patients. It is known that both of these properties are associated with increased magnesium levels. The effect of sevelamer on serum magnesium level is not well documented. The aim of this study was to determine the effects of sevelamer treatment on serum magnesium in haemodialysis patients and to assess the association of magnesium levels with lipid profiles and intact parathyroid hormone (iPTH). Methods: Phosphate binders were discontinued during a two week washout period. Forty-seven patients, whose serum phosphate was greater than 6.0 mg/dl at the end of washout, received sevelamer hydrochloride for eight weeks. The patients were then washed off sevelamer for another two weeks. Results: Mean serum phosphorus concentration declined from 7.5 ± 1.3 to 6.4 ± 1.2 mg/dl (P < 0.001), mean serum magnesium levels increased from 2.75 ± 0.35 to 2.90 ± 0.41 mg/dl (P < 0.001) and median serum iPTH levels decreased from 297 to 213 pg/ml (P=0.001) during the eight weeks of sevelamer treatment. After the two week post-treatment washout phosphorus levels increased to 7.3 ± 1.3 mg/dl (P < 0.001), magnesium levels were reduced to 2.77 ± 0.39 mg/dl (P < 0.001) and iPTH levels increased to 240 pg/ml (P=0.012). No change was observed in serum calcium levels during the sevelamer treatment period and the subsequent washout period. The mean decline in total and low density lipoprotein (LDL) cholesterol during sevelamer treatment was 16.3 and 28.3 (P < 0.001), respectively. The mean increase in high density lipoprotein (HDL) cholesterol and in apolipoprotein A1 was 2.9 ± 5.8 mg/dl (P=0.004) and 6.8 ± 11.1 mg/dl (P=0.001), respectively. Multivariate analysis showed that the rise in serum magnesium concentration significantly correlated with reductions in iPTH levels (r=−0.40, P=0.016), but did not have any significant correlation with the changes in lipid profiles. Conclusions: Our findings indicate that patients on haemodialysis receiving sevelamer have a significant increase in serum magnesium concentrations. This increase in serum magnesium is associated with reduction in iPTH levels. The changes in lipid profiles of these patients however are not related to changes in serum magnesium levels. 相似文献

Does the Presence of Anti-CCP Autoantibodies and Their Serum Levels Influence the Severity and Activity in Rheumatoid Arthritis Patients? 总被引:1,自引:0,他引:1

This study aims to investigate the association of the presence and of the titer of autoantibodies against cyclic citrullinated
peptides (aCCP), with clinical manifestations and disease activity in a cohort of patients with rheumatoid arthritis (RA).
From January 2000 through December 2005, 135 patients were diagnosed with RA at the Rheumatology Unit of our hospital. Demographic,
clinical, laboratory, and therapeutic parameters were evaluated in all patients at study entry and at every follow-up visit.
Positivity in aCCP and also their levels were determined for all patients. At the end of the study, we reevaluated the above
parameters, dividing patients into aCCP positive and aCCP negative. From 135 patients, 53.3% were aCCP positive. The majority
of aCCP-positive patients were males (p < 0.001), positive to rheumatoid factor (p < 0.001) and current smokers (p < 0.05). At diagnosis, aCCP-positive patients presented with higher tender joint counts (p < 0.001) and swollen joint counts (p < 0.001), and exhibited more active disease, expressed by higher disease activity scores for 28 joints (DAS-28) (p < 0.001). At the end of the study, aCCP-positive patients also displayed more active disease, with higher DAS-28 (p < 0.001), and more severe disease, as this was indicated by the higher radiological Larsen score (p < 0.001). The serum levels of aCCP were not found to be associated with disease activity and severity. In early RA, the presence
of aCCP is associated with increased disease activity and severity. This was found to be independent of circulating levels
of aCCP. 相似文献

The study aims to explore the lifestyle profile of adult individuals with cardiovascular and endocrine diseases in Cyprus. Age and sex-specific analyses were applied. A representative sample of the general adult population was recruited during 2018–2019 using stratified sampling among the five government-controlled municipalities of the Republic of Cyprus. Data on Mediterranean diet adherence, quality of sleep, smoking status, physical activity, Body Mass Index, and the presence of cardiovascular and endocrine diseases were collected using a validated questionnaire. Diseases were classified according to the International Classification of Diseases, Tenth Revision (ICD-10). A total of 1140 men and women over 18 years old (range: 18–94) participated in the study. The prevalence of cardiovascular and endocrine diseases among the adult general population of Cyprus was 24.8% and 17.2%, respectively, with a higher prevalence of cardiovascular diseases in men, and a higher prevalence of endocrine diseases in women. Among individuals with cardiovascular disease, 23.3% were aged between 18–44 years old, while the corresponding percentage among endocrine disease individuals was 48%. The prevalence of smoking, physical activity, a low adherence to the Mediterranean diet, poor quality of sleep and obesity among the study population was 35.5%, 48.0%, 32.9%, 39.0% and 13.6%, respectively. Individuals with cardiovascular and endocrine diseases were characterized by poor quality of sleep, inadequate physical activity, and a higher BMI. This is the first study in Cyprus exploring the profile of individuals with cardiovascular and endocrine diseases in Cyprus. Health promotion and educational programs focusing on the importance of sleep quality, healthier dietary habits, physical activity, and lower BMIs among people with cardiovascular and endocrine diseases should be developed. 相似文献

Groove pancreatitis is a distinct form of chronic pancreatitis characterized by inflammation and fibrous tissue formation,
affecting the groove area between the head of the pancreas, the duodenum and the common bile duct. It is manifested on imaging
by a sheet-like mass in the groove area near the minor papilla. Thickening of the duodenal wall and cystic transformation
in the duodenal wall also represent common imaging features. Pathogenesis is still unclear, and clinical presentation is not
specific. Endoscopic ultrasonography (EUS), computed tomography (CT) and magnetic resonance imaging (MRI) demonstrate imaging
findings consistent with the disease in typical cases, but specific diagnosis is challenging in a number of patients where
biopsy is required. The disease may mimic pancreatic, common bile duct or duodenal wall cancer that requires prompt and excessive
surgical intervention, as opposed to groove pancreatitis where initial conservative treatment is suggested. The clinical,
histopathological and radiological features on cross-sectional imaging of this entity are discussed in this review, and differential
diagnostic clues are given. 相似文献

Haemophilus influenzae (Hi), Moraxella catarrhalis (MorCa) and Pseudomonas aeruginosa (Psa) are three of the most common gram-negative bacteria responsible for human respiratory diseases. In this study, we aimed to identify, using the functional enrichment analysis (FEA), the human gene interaction network with the aforementioned bacteria in order to elucidate the full spectrum of induced pathogenicity. The Human Pathogen Interaction Database (HPIDB 3.0) was used to identify the human proteins that interact with the three pathogens. FEA was performed via the ToppFun tool of the ToppGene Suite and the GeneCodis database so as to identify enriched gene ontologies (GO) of biological processes (BP), cellular components (CC) and diseases. In total, 11 human proteins were found to interact with the bacterial pathogens. FEA of BP GOs revealed associations with mitochondrial membrane permeability relative to apoptotic pathways. FEA of CC GOs revealed associations with focal adhesion, cell junctions and exosomes. The most significantly enriched annotations in diseases and pathways were lung adenocarcinoma and cell cycle, respectively. Our results suggest that the Hi, MorCa and Psa pathogens could be related to the pathogenesis and/or progression of lung adenocarcinoma via the targeting of the epithelial cellular junctions and the subsequent deregulation of the cell adhesion and apoptotic pathways. These hypotheses should be experimentally validated. 相似文献

In vitro evaluation of nimodipine permeation through human epidermis using response surface methodology 总被引:4,自引:0,他引:4

An optimization technique (response surface method) was used in order to investigate the effect of the combination of two enhancers, namely caprylic acid and cineol on nimodipine's permeation through human cadaver epidermis. Using this quadratic model it was found that at 24 h the increase of the permeation of nimodipine it was mainly due to the effect of caprylic acid. On the contrary, it was shown that at 48 and 72 h the combination of the two enhancers contributed to the increase of the permeation. The greater Q(gel)/Q(control) values, at all time intervals (24, 48 and 72 h), were obtained when the concentration of cineol and caprylic acid range from 3.0 to 5.0% (v/v) and 8.0 to 9.5% (v/v), respectively. 相似文献
