Aim of the work
To present the clinical and laboratory disease characteristics in Egyptian patients with progressive systemic sclerosis (SSc) and their nail fold capillaroscopy findings.Patients and methods
50 SSc patients were included. For all patients detailed history taking and clinical and rheumatological examination were performed. The modified Rodnan skin score (mRSS) and nail fold capillaroscopy were assessed.Results
The mean age was 41.4?±?12.7?years (range 16–67?years) and median disease duration was 5?years (range 1–40?years). Eight patients (16%) were males and 42 (84%) females (M:F 1:5.25). Skin tightness was present in all patients; mean mRSS was 17.5?±?10.4 (ranges 4–45). 44 (88%) patients had abnormal pulmonary function tests; 42 (84%) restrictive and 2 (4%) obstructive; 25 (50%) presented with interstitial lung disease. Pulmonary artery hypertension was recorded in 9 (18%) patients. Renal manifestations were the least common recorded system involvement (20%). Antinuclear antibodies were positive in 98%, rheumatoid factor in 4%, antitopoisomerase I in 36% and anticentromere in 8% of patients. 96% of patient had abnormal nail fold capillaroscopy. There was a significant negative correlation between mRSS with forced expiratory volume (r?=??0.46, p?=?0.001), forced volume capacity (r?=??0.47, p?=?0.001) and positively with the FEV1/FVC (r?=?0.3, p?=?0.035).Conclusion
Almost all patients have ANA seropositivity, abnormal PFTs and abnormal nailfold capillaroscopy. Antitopoisomerase I antibody seropositivity, ILD, abnormal PFT, worsening skin score, late pattern of nailfold capillaroscopy are more common in dcSSc. Extensive clinical examination and investigations should be considered for early diagnosis and follow up of Egyptian SSc patients. 相似文献3.

AimsThe aim of the present study was to investigate retinal nerve fiber layer (RNFL) thickness in patients with type 2 diabetes mellitus (T2D) using spectral-domain optical coherence tomography and to evaluate the relationship between RNFL thickness and carotid intima media thickness (CIMT).MethodsThis study included 171 patients with T2D (53.2 ± 8.8 years) and age matched 61 healthy controls (51.9 ± 8.1 years). We evaluated anthropometric and metabolic parameters as well as RNFL and CIMT measurements in patients with T2D and controls. The Mann–Whitney U test was used to compare the continuous variables and the Chi-square test was used to compare categorical variables. Spearmanʼs rank correlation test was used for calculation of associations between variables.ResultsThe average RNFL thickness was 84.82 ± 11.22 μm in patients with T2D and 92.35 ± 8.45 μm in healthy controls (p < 0.001). Mean CIMT values were higher in patients with T2D (0.80 ± 0.1 mm) than the healthy subjects (0.72 ± 0.1 mm) (p < 0.001). A significant negative correlation was found between age and all quadrants of RNFL. There was a negative correlation between average RNFL thickness and HbA1c (r = −0.176), uric acid (r = −0.145), CIMT (r = −0.190) and presence of carotid plaque (r = −0.193). The superior RNFL thickness was negatively associated with HbA1c (r = −0.175), CIMT (r = −0.207) and carotid plaque (r = −0.176). There was also an inverse correlation between the inferior RNFL thickness and HbA1c (r = −0.187) and carotid plaque (r = −0.157).ConclusionThinning of RNFL might be associated with atherosclerosis in patients with T2D. 相似文献

AIMS:
Patients with type-2 diabetes mellitus have greater carotid intima media thickness and they are at risk for generalized atherosclerosis. This study aimed to compare the thickness of carotid artery intima media in type-2 diabetes mellitus patients with and without nonblood pressure component metabolic syndrome.SETTINGS AND DESIGN:
This was a comparative observational study conducted in the Departments of Pharmacology and Physiology in the College of Medicine, Al-Mustansiriyia University in cooperation with Baghdad Teaching Hospital.MATERIALS AND METHODS:
Forty-six diabetic patients of both sexes with systolic blood pressure < 130 mm Hg and diastolic blood pressure < 85 mm Hg were subjected to high resolution B-mode ultrasonography of the common and internal carotid arteries. Patients were grouped into those without metabolic syndrome (Group I) and with nonblood pressure component metabolic syndrome (Group II).STATISTICAL ANALYSIS:
The two-tailed unpaired Student''s t-test was used in this study.RESULTS:
Significantly high mean thickness was observed in the common carotid intima media (0.824 ± 0.155 mm) but not in the internal carotid arteries in group II patients compared to group I patients (0.708 ± 0.113 mm). Group II also had a significant number of patients with increased lesion intima media thickness (≥ 1.1 mm).Conclusion:
The greater carotid intima media thickness observed in type 2 diabetes mellitus patients is related to the metabolic syndrome even in the absence of the blood pressure component. 相似文献6.

AimsTo review: 1) the correlation between individual dietary components and carotid intima media thickness (cIMT); 2) the relationship between dietary patterns and cIMT; 3) the effect of dietary interventions on cIMT progression.Data synthesisAn electronic search for epidemiological and intervention trials investigating the association between dietary components or patterns of intake and cIMT was performed in PUBMED, EMBASE and the Cochrane Library. Epidemiological data shows that a higher intake of fruit, wholegrains and soluble fibre and lower consumption of saturated fat in favour of polyunsaturated fat is associated with lower cIMT. In people at high risk of cardiovascular disease >93 g/day of fruit is associated with lower cIMT. Lower cIMT has also been observed when >0.79 serves/day of wholegrains and >25 g/day of fibre, predominately in the soluble form is consumed. Saturated fat is positively associated with cIMT, for every 10 g/day increase in saturated fat cIMT is 0.03 mm greater. Olive oil is inversely associated with cIMT, with a benefit seen when >34 g/day is consumed. While there are many epidemiological studies exploring the association between dietary intake and cIMT there are few intervention studies. Intervention studies show that a Mediterranean diet may reduce cIMT progression, especially in those with a higher cIMT.ConclusionsA Mediterranean style dietary pattern, which is high in fruits, wholegrains, fibre and olive oil and low in saturated fat, may reduce carotid atherosclerosis development and progression. However further research from randomised controlled trials is required to understand the association between diet and cIMT and the underlying mechanisms. 相似文献

Background and aims
Cardiovascular disease (CVD) is one of the leading causes of mortality in obese patients. We aimed to investigate the influence of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on carotid intima media thickness (CIMT) and epicardial fat thickness (EFT) which are the independent predictors of subclinical atherosclerosis.Methods and results
Patients were recruited for standard indications. A total of 105 patients (79 women and 26 men) with the mean age of 43.61 ± 12.42 were prospectively enrolled. On B-mode duplex ultrasound; the mean CIMT at the far wall of both left and right common carotid arteries were measured. EFT was measured on the free wall of the right ventricle at end-diastole from the parasternal long-axis view by standard transthorasic 2D echocardiography. Delta (Δ) values were obtained by subtracting sixth month values from the baseline values. Body mass index (BMI) was significantly reduced from 46.95 ± 7.54 to 33.54 ± 6.41 kg/m2 (p < 0.001) in sixth months after LSG. Both EFT and CIMT were significantly decreased after surgery (8.68 ± 1.95 mm vs. 7.41 ± 1.87 mm; p < 0.001 and 0.74 ± 0.13 mm vs. 0.67 ± 0.11 mm; p < 0.001 respectively). A significant correlation between ΔEFT and ΔBMI (r = 0.431, p < 0.001) was shown. ΔCIMT is significantly correlated with ΔEFT, ΔBMI and Δ systolic blood pressure (r = 0.310, r = 0.285 and r = 0.231 respectively, p < 0.05 for all). In multivariate stepwise linear regression analysis; among variables only ΔBMI was the independent predictor of ΔEFT (β = 153, p = 0.001).Conclusion
Early atherosclerotic structural changes may be reversed or improved by sustained weight loss after LSG in asymptomatic obese patients. 相似文献8.

Aims/hypothesis Intima media thickness (IMT) of the common carotid artery (CCA) is a validated surrogate marker of early atherosclerosis. The aim of our study was to assess the association between IMT in CCA and long-term mean HbA1c in type 1 diabetes. We also elucidated the association between carotid IMT and preclinical coronary atherosclerosis.Methods In 39 individuals with type 1 diabetes, HbA1c was measured prospectively over 18 years. The IMT examinations were performed with high-resolution ultrasound. The association between carotid IMT and preclinical coronary atherosclerosis (assessed by intravascular ultrasound [IVUS]) was tested in 29 of the patients.Results Mean HbA1c over 18 years was 8.2% (range: 6.6–11.3%). Mean age at follow-up after 18 years was 43 years and mean duration of diabetes was 30 years. IMT was significantly higher in diabetic patients than in an age- and sex-matched reference population. The IMT values were at the same level as for controls who were 20 years older. In women, HbA1c was significantly associated with mean average CCA IMT (r2=0.77, p<0.0001 when adjusted for age), whereas there was no significant association for men. Among women, a significant association was also found between carotid IMT and the percentage of coronary vessel area stenosis (r=0.65, p=0.03).Conclusions/interpretation The present findings suggest an important role of long-term hyperglycaemia in the development of atherosclerosis, especially in women with type 1 diabetes.Type 1 diabetes patients have earlier development of, and more advanced, atherosclerosis compared with an age- and sex-matched reference population. In women, carotid IMT reflects preclinical coronary atherosclerosis. 相似文献

Summary We analysed the relationship between fasting plasma glucose, carotid intima media thickness and some atherosclerosis risk
factors in 307 non-diabetic individuals. Male (n = 120) and female subjects (n = 187) with a familial history of Type II diabetes mellitus and/or obesity and hyperlipoproteinaemia were examined in the
age group 40–70 years. Plasma triglycerides, total and high-density-lipoprotein cholesterol, plasminogen activator inhibitor
were measured by conventional methods. Specific insulin, proinsulin and C-peptide were measured by specific enzyme immunoassay.
Intima media thickness increased in quintiles for fasting plasma glucose in men, but not in women. There was a rise of triglycerides,
body mass index, waist to hip ratio, plasminogen activator inhibitor, true insulin, proinsulin, C-peptide and a decrease of
high-density-lipoprotein cholesterol in quintiles for fasting plasma glucose. Fasting plasma glucose was found to be significantly
positively correlated to intima media thickness, body mass index, waist to hip ratio, haemoglobin A1 c, insulin, C-peptide, triglycerides, plasminogen activator inhibitor and significantly negatively correlated to high density
lipoprotein cholesterol. However, the correlation of fasting plasma glucose to intima media thickness was no longer significant
after adjustment for age and sex. After adjustment for age and sex intima media thickness was significantly correlated to
body mass index, total cholesterol, triglycerides, albuminuria and inversely correlated to high-density-lipoprotein cholesterol.
In multivariate analysis age, male sex, high-density-lipoprotein cholesterol and total cholesterol were significant determinants
of intima media thickness. Our data suggest that a weak association exists between fasting plasma glucose and intima media
thickness, which may be mediated by a clustering of risk factors in the upper range of non-diabetic fasting plasma glucose
level with a central role for dyslipidaemia. [Diabetologia (1998) 41: 706–712]

AIMS: The ADIPOQ gene encodes the protein adiponectin, and decreased circulating adiponectin levels have been observed in cardiovascular disease. We investigated the role of the ADIPOQ gene single-nucleotide polymorphisms (SNPs) A-11426G, G-11391A, C-11377G, and T45G with plasma adiponectin levels and common carotid artery intima media thickness (IMT) in a cohort of healthy subjects participating in the RISC (Relationship between Insulin Sensitivity and Cardiovascular disease) study. METHODS AND RESULTS: Anthropometric and metabolic assessment and B-mode ultrasound of the carotid IMT were measured in 1306 subjects [589 men; 717 women, mean +/- SD age 43.8 +/- 8.3 years, BMI 25.5 +/- 4.0 kg/m(2)] recruited from 19 centres in 14 European countries. Carriers of the -11426G allele and homozygous carriers of the -11391G allele had significantly lower plasma adiponectin levels. These relationships remained significant after adjusting for age, sex, recruitment centre, and BMI. Carriers of SNP -11377G allele had significantly greater IMT values compared with C allele homozygotes [geometric mean (interquartile range) 601 (543-665) vs. 590 (537-647) mum, P = 0.021]. This relationship became stronger after correcting for key covariates, including plasma adiponectin levels (P = 0.011). CONCLUSION: Variation within the ADIPOQ gene promoter is directly associated with carotid IMT in healthy subjects and is independent of circulating adiponectin levels. 相似文献

The aim of the present study was to determine whether intima-media thickness (IMT) of the common (CCA) and internal carotid
arteries (ICA) was increased due to chronic inflammation occurring in familial Mediterranean fever (FMF) patients compared
to healthy controls. Erythrocyte sedimentation rate (ESR), serum C-reactive protein (CRP), serum amyloid A protein (SAA),
lipid profile and homocysteine levels were examined in 70 FMF patients [median age 14 years (range 4–24)] in an attack free
period and in 50 healthy controls [median age 14 years (range 4–18)]. All the patients were homozygous or compound heterozygous
for MEFV mutations. IMT of both CCA and ICA was evaluated with a high resolution B-mode ultrasonography. ESR, CRP, fibrinogen
and SAA levels were significantly higher in FMF patients as compared to healthy controls (P < 0.05). Intima media thickness of the common carotid artery was found to be significantly higher in FMF patients when compared
to those in healthy controls [0.37 mm (0.26–0.61) vs. 0.28 mm (0.21–0.35), P < 0.001]. The median ICA-IMT was significantly increased in the patients when compared to those in the controls [0.25 mm
(0.18–0.44) vs. 0.22 mm (0.10–0.26), P < 0.001]. A positive correlation between CCA-IMT and SAA levels (r = 0.24, P = 0.04) was found while ICA-IMT positively correlated with ESR (r = 0.31, P = 0.008) and fibrinogen levels (r = 0.30, P = 0.012). Intima media thickness, an early predictor of atherosclerosis, may be associated with subclinical inflammation
in children with FMF. Further studies will enlighten whether these patients will be predisposed more to coronary artery disease.

BackgroundCardiac involvement in systemic sclerosis (SSc) is often clinically occult. The aim of this study was the evaluation of early subclinical right ventricular (RV) involvement in patients with limited form of systemic sclerosis by tissue Doppler.MethodsTwenty female patients with limited cutaneous SSc and 20 control female subjects, matched for age were studied with transthoracic echocardiography and tissue Doppler imaging (TDI) to assess RV function. Patients with pulmonary hypertension, chronic renal failure, diabetes mellitus, hypertension, heart failure, left ventricular hypertrophy, ischemic or rheumatic heart disease were excluded.ResultsPatients with limited form SSc had significant lower tricuspid annulus peak systolic velocities (ST) (9.95 ± 1.78 vs. 11.05 ± 1.53 cm/s, p < 0.044), early (ET) (9.65 ± 1.30 vs. 12.50 ± 1.23 cm/s, p < 0.0001), late (AT) diastolic velocity (12.60 ± 2.01 vs. 18.15 ± 1.81 cm/s, p < 0.0001), and tricuspid annular plane systolic excursion (TAPSE) (23.05 ± 3.50 vs. 26.50 ± 1.90, p < 0.001) compared to controls. Myocardial performance index (MPI) of the RV was higher in SSc patients compared to controls (0.41 ± 0.05 vs. 0.30 ± 0.02, p < 0.0001). There were significant correlations between disease duration and ST and RV MPI (r = ?0.883, p < 0.0001; r = 0.686, p < 0.001, respectively).ConclusionsPatients with limited form of SSc present with pulsed-tissue Doppler imaging indices indicative of right ventricle dysfunction, which had significant correlations with disease duration. Tissue Doppler is a valuable non-invasive tool for detecting RV myocardial involvement in patients with limited SSc. 相似文献

Objective: Since asthma and atherosclerosis may share similar pathophysiological mechanism, this study is planned to investigate whether epicardial fat thickness (EFT), carotid and femoral intima media thicknesses, which are markers of subclinical atherosclerosis, are increased in patients with asthma. Methods: The study was designed as a cross-sectional study. A total of 154 participants (83 patients with asthma and 71 healthy volunteers) were enrolled into the study. Epicardial fat, carotid, and femoral intima media thicknesses were measured and recorded in both groups. The statistical difference between the two groups was examined. Results: Both carotid and femoral intima media thicknesses were significantly higher in patients with asthma compared to control group (5.52 ± 0.4 mm vs. 5.36 ± 0.4 mm; p = 0.038 and 5.64 ± 0.4 mm vs. 5.46 ± 0.5 mm; p = 0.036, respectively). However, there was not a significant difference in EFT between the groups [5.9 mm (5.3–6.6; IQR = 1.3) vs. 5.6 mm (4.7–6.5; IQR = 1.8); p = 0.1]. On comparison of control group and asthma subgroups (mild, moderate, and severe), there was a statistically significant difference among these four groups in terms of carotid and femoral intima media thicknesses (p = 0.002 and p < 0.001, respectively). Subgroup analyses showed that this difference was mainly due to patients with severe asthma. Conclusions: Carotid and femoral intima media thicknesses in asthmatic patients were found to be increased compared to the normal population. As a result, the risk of subclinical atherosclerosis in asthmatic patients may be high. 相似文献

Background and aims
The relationship between dietary intake and carotid intima media thickness (IMT) and pulse wave velocity (PWV) in individuals with type 1 and type 2 diabetes has not been well studied. We investigated the association between dietary intake and common carotid artery intima media thickness (CCA IMT) and PWV in a cohort with type 1 and type 2 diabetes.Methods and results
A one-year randomised controlled trial was conducted to investigate the effect of improving dietary quality on CCA IMT. These subjects were followed up again approximately 12 months after the completion of the trial (i.e. approximately 24 month since baseline). The study cohort included 87 subjects that had dietary intake and CCA IMT measured at baseline and after a mean of 2.3 years' follow-up. PWV was measured in a subsample of this cohort.Age and baseline mean CCA IMT were strongly associated with mean CCA IMT at 24 months. After adjustment for age and baseline mean CCA IMT, baseline consumption of carbohydrate (r = ?0.28; p = 0.01), sugars (r = ?0.27; p = 0.01), fibre (r = ?0.26; p = 0.02), magnesium (r = ?0.25; p = 0.02) and the Alternate Health Eating Index (AHEI) score (r = ?0.23; p = 0.03) were inversely associated with mean CCA IMT at 24 months. Mixed linear modelling showed an interaction between mean CCA IMT and AHEI at baseline (p = 0.024). Those who were in the highest AHEI tertile at baseline had greater CCA IMT regression at 24 months compared to those in the lowest tertile, after adjustment for baseline age, BMI, smoking pack years, time since diabetes diagnosis, and mean arterial pressure at baseline (mean ?0.043 mm; 95% CI -0.084, ?0.003; p = 0.029).Conclusions
In this prospective analysis greater diet quality at baseline, as measured by the AHEI, was associated with greater CCA IMT regression after approximately two years. This suggests that greater diet quality is associated with better longer term vascular health in individuals with type 1 and type 2 diabetes. 相似文献18.

Introduction: Vascular involvement plays a decisive role in systemic sclerosis (SSc) pathogenesis; it is responsible for some important clinical manifestations of the disease such as Raynaud’s phenomenon and digital ulcers (DU). Bosentan, a dual receptor endothelin antagonist, and iloprost, often in combination therapy, seems to be able to interfere with the scleroderma microangiopathy.Objectives: Aim of the study was to evaluate the effect of bosentan and iloprost on scleroderma microangiopathy, analyzed by means of capillaroscopic skin ulcer risk index (CSURI), in SSc patients treated for the prevention of DU.Methods: Nailfold videocapillaroscopy (NVC) was performed in 95 SSc patients, treated with iloprost alone (group 1) or combination therapy with iloprost and bosentan (group 2), at baseline and after one year. In all patients CSURI was calculated according to the formula “diameter?×?number of megacapillaries/(total number of capillaries)2”: in addition, total number of capillaries, giant capillaries, micro-hemorrhages, disorganization of the vascular array, and ramified capillaries were evaluated by means of a semiquantitative score.Results: After 12 months, we observed a reduction of the number of giant capillaries in both groups, while an increase of ramified capillaries was recorded only in group 2. CSURI improved slightly in group 2 without statistical significance; on the contrary, in group 1 a significant worsening was recorded (p?≤?0.001).Conclusions: Our study confirms the effectiveness of bosentan, in combination with iloprost, in SSc microangiopathy observed to NVC. Moreover, the observed findings further support the role of CSURI in the evaluation and monitoring of SSc microangiopathy. 相似文献

Aim: The objectives of this study were to investigate the frequency of thickened carotid intima media thickness (CIMT) and atherosclerosis among lupus nephritis (LN) patients and to study their associated risk factors. Method: In this cross‐sectional study, carotid ultrasonography was performed on consecutive LN patients to determine CIMT and presence of carotid plaques. CIMT was considered to be abnormally thickened if it was more than the 75th percentile matched for age and sex from the ‘Carotid Atherosclerosis Progression Study’. The association between thickened CIMT with traditional cardiovascular risk factors and lupus characteristics were examined. A total of 83 patients with the mean age of 33.6 ± 10 years were recruited. Results: Fourteen patients (16.9%) had thickened CIMT and three (3.6%) had carotid plaques. On univariate analysis, traditional risk factors significantly associated with thickened CIMT (P < 0.05) were patient’s current age, diabetes mellitus and waist circumference. Meanwhile, a lower serum C4 levels and higher serum C‐reactive protein levels were the lupus‐specific factors associated with thickened CIMT (P < 0.05, P < 0.05 and P < 0.01, respectively). In logistic regression analysis, the independent predictors of thickened CIMT were age of diagnosis, lower serum C4 levels and waist circumference (P < 0.05). Conclusion: More lupus specific factors were independently associated with thickened CIMT, suggesting that a multi‐targeted approach of treatment addressing both the lupus and traditional cardiovascular risks are very important. Larger prospective studies of these special risk factors are indicated. 相似文献
