Knowledge and understanding risk factors and preventive measures for osteoporosis in women: results of a survey in 502 women with and without a migration background.

BACKGROUND: Osteoporosis is a disease of the skeletal system associated with loss of bone mass and an increased risk of fractures affecting women more often than men. Identification of the knowledge about osteoporosis and its preventive methods is the backbone of any awareness program. This study investigates the knowledge with a special focus on women with and without a migration background. METHODS: Data from systematic patient interviews based on a questionnaire were collected at three different sites in Berlin between February and June 2021. The survey included questions assessing migrant background, demographic characteristics, lifestyle habits including physical exercise and smoking, prevention by vitamin D intake and bone densitometry, and information on personal and family medical history. According to the responses, a scale was created to assess the level of knowledge of preventive osteoporosis measures. The ethic committee of the Charité, Medical faculty has approved this study. SPSS (version 24.0) was used for the statistical analyses. RESULTS: The survey of 502 female patients revealed that 25% had low and 34% no previous knowledge of osteoporosis. Older age and a better education level correlate with a higher knowledge. Patients with gynecologic cancer are less well informed. There is a significant difference in vitamin D intake between migrant and non-migrant women (57% vs. 49%). There were no significant differences regarding the use of bone densitometry. CONCLUSION: Knowledge of osteoporosis and the possibility of a bone densitometry as well as the implementation of preventive measures is low among women. Therefore, informing patients better should be a priority, with particular attention on the risks and needs of women with a migration background. Specific programs for women with and without migration background should be developed to increase the awareness of osteoporosis.

Outcome of revascularization therapy in traumatized immature incisors.

BACKGROUND: The aim of this retrospective analysis was to evaluate the clinical and radiological outcome of revascularization therapy in traumatized permanent incisors to determine whether this approach could be implemented into clinical routine. METHODS: A total of 16 traumatized incisors (either avulsion or severe luxation/intrusion) with open apices (> 1 mm) that underwent revascularization following a standardized protocol were analyzed with a mean follow-up of 22 months. Radiographs and clinical parameters (such as root length, pulp space, dentin wall width, apical foramen, alveolar bone loss, ankylosis/mobility, supra-/infraposition, discoloration, probing depth) were compared pre- and postoperatively and statistically analyzed. RESULTS: Over the follow-up period, 81.3% of the teeth survived revascularization and regained sensitivity, while 18.7% failed, as they had to be extracted due to serious root resorption. Regarding radiographic outcomes a significant difference could only be found in the decrease of apical foramina (p = 0.04). The other parameters showed no significant difference between pre- and postoperative measurements. More than half of the teeth (56.3%) developed root resorptions and 31.3% displayed signs of ankylosis and 92.9% developed discolorations during follow-up. However, 85.7% of the teeth maintained the bone level and outcomes of mobility showed a significant solidification. CONCLUSIONS: Revascularization is a promising approach for the treatment of immature incisors to regain sensitivity and to enhance apical closure and at least to maintain alveolar bone in terms of a socket preservation. Further studies have to be performed to determine ideal conditions (type of trauma, age, width of apical foramen) for a revascularization.

The association of profilin-1 levels with survival in chronic kidney disease.

BACKGROUND: Profilin-1 is a ubiquitous, actin-binding protein that plays an important role in the regulation of actin polymerization and cytoskeleton remodelling and contributes to vascular dysfunction. We conducted this study to investigate the association of serum profilin-1 levels with fatal and nonfatal CVE in a cohort of patients with stage 1-5 CKD. MATERIALS AND METHODS: Serum concentrations of profilin-1 levels were determined by enzyme-linked immunosorbent assay. Endothelium-dependent vasodilatation (flow-mediated dilatation [FMD]) and endothelium-independent vasodilatation (nitroglycerine-mediated dilatation [NMD]) of the brachial artery were assessed noninvasively, using high-resolution ultrasound. RESULTS: Both fatal and nonfatal CVE were significantly higher in patients with high profilin-1 levels. Kaplan-Meier survival curves showed that patients with profilin-1 below the median value (114 pg/mL) had higher cumulative survival compared with patients who had profilin-1 levels above the median value (log-rank test, P < .001). CONCLUSIONS: This is the first study that demonstrates the serum profilin-1 is independently associated with endothelial dysfunction, cardiovascular events and survival in patients with CKD.

Comparison of fiber delivered CO2 laser and electrocautery in transoral robot assisted tongue base surgery.

To compare intra-operative and post-operative effectiveness of fiber delivered CO2 laser to monopolar electrocautery in robot assisted tongue base surgery. Prospective non-randomized clinical study. Twenty moderate to severe obstructive sleep apnea (OSA) patients, non-compliant with Continuous Positive Airway Pressure (CPAP), underwent Transoral Robotic Surgery (TORS) using the Da Vinci surgical robot in our University Hospital. OSA was treated with monopolar electrocautery in 10 patients, and with flexible CO2 laser fiber in another 10 patients. The following parameters in the two sets are analyzed: Intraoperative bleeding that required cauterization, robot operating time, need for tracheotomy, postoperative self-limiting bleeding, length of hospitalization, duration until start of oral intake, pre-operative and post-operative minimum arterial oxygen saturation, pre-operative and post-operative Epworth Sleepiness Scale score, postoperative airway complication and postoperative pain. Mean follow-up was 12 months. None of the patients required tracheotomy and there were no intraoperative complications related to the use of the robot or the CO2 laser. The use of CO2 laser in TORS-assisted tongue base surgery resulted in less intraoperative bleeding that required cauterization, shorter robot operating time, shorter length of hospitalization, shorter duration until start of oral intake and less postoperative pain, when compared to electrocautery. Postoperative apnea-hypopnea index scores showed better efficacy of CO2 laser than electrocautery. Comparison of postoperative airway complication rates and Epworth sleepiness scale scores were found to be statistically insignificant between the two groups. The use of CO2 laser in robot assisted tongue base surgery has various intraoperative and post-operative advantages when compared to monopolar electrocautery.

Osteoprotegerin in Chronic Kidney Disease: Associations with Vascular Damage and Cardiovascular Events.

Vascular injury and dysfunction contribute to cardiovascular disease, the leading cause of death in patients with chronic kidney disease (CKD). Osteoprotegerin (OPG) is a soluble member of the tumor necrosis factor receptor superfamily that has been linked to atherogenesis and endothelial dysfunction. Elevated circulating OPG levels predict future cardiovascular events (CVE). Our aim was to evaluate the determinants of circulating OPG levels, to investigate the relationship between OPG and markers of vascular damage and to test whether OPG improves risk stratification for future CVE beyond traditional and renal-specific risk factors in a CKD population. 291 patients with CKD stage 1-5 not on dialysis were included in the study. In the multivariate analysis, OPG was a significant predictor for flow-mediated dilatation, but not for carotid intima media thickness levels. During follow-up (median 36 months, IQR = 32-42 months), 87 patients had CVE. In the Cox survival analysis, OPG levels were independently associated with CVE even after adjustment for traditional and renal-specific cardiovascular risk factors. The addition of OPG to a model based on commonly used cardiovascular factors significantly improved the reclassification abilities of the model for predicting CVE. We show for the first time that OPG improves risk stratification for CVE in a non-dialysis CKD population, above and beyond a model with established traditional and renal-specific cardiovascular risk factors, including estimated glomerular filtration rate and fibroblast growth factor 23.

The Prevalence of Fabry Disease in Patients with Chronic Kidney Disease in Turkey: The TURKFAB Study.

BACKGROUND/AIMS: Fabry disease is a treatable cause of chronic kidney disease (CKD) characterized by a genetic deficiency of α-galactosidase A. European Renal Best Practice (ERBP) recommends screening for Fabry disease in CKD patients. However, this is based on expert opinion and there are no reports of the prevalence of Fabry disease in stage 1-5 CKD. Hence, we investigated the prevalence of Fabry disease in CKD patients not receiving renal replacement therapy. METHODS: This prospective study assessed α-galactosidase activity in dried blood spots in 313 stage 1-5 CKD patients, 167 males, between ages of 18-70 years whose etiology of CKD was unknown and were not receiving renal replacement therapy. The diagnosis was confirmed by GLA gene mutation analysis. RESULTS: Three (all males) of 313 CKD patients (0.95%) were diagnosed of Fabry disease, for a prevalence in males of 1.80%. Family screening identified 8 aditional Fabry patients with CKD. Of a total of 11 Fabry patients, 7 were male and started enzyme replacement therapy and 4 were female. The most frequent manifestations in male patients were fatigue (100%), tinnitus, vertigo, acroparesthesia, hypohidrosis, cornea verticillata and angiokeratoma (all 85%), heat intolerance (71%), and abdominal pain (57%). The most frequent manifestations in female patients were fatigue and cornea verticillata (50%), and tinnitus, vertigo and angiokeratoma (25%). Three patients had severe episodic abdominal pain attacks and proteinuria, and were misdiagnosed as familial Mediterranean fever. CONCLUSIONS: The prevalence of Fabry disease in selected CKD patients is in the range found among renal replacement therapy patients, but the disease is diagnosed at an earlier, treatable stage. These data support the ERBP recommendation to screen for Fabry disease in patients with CKD of unknown origin.

The role of plasma triglyceride/high-density lipoprotein cholesterol ratio to predict cardiovascular outcomes in chronic kidney disease.

BACKGROUND: Cardiovascular disease (CVD) risk is substantially increased in subjects with chronic kidney disease (CKD). The Triglycerides (TG) to High-Density Lipoprotein Cholesterol (HDL-C) ratio is an indirect measure of insulin resistance and an independent predictor of cardiovascular risk. No study to date has been performed to evaluate whether the TG/HDL-C ratio predicts CVD risk in patients with CKD. METHODS: A total of 197 patients (age 53±12 years) with CKD Stages 1 to 5, were enrolled in this longitudinal, observational, retrospective study. TG/HDL-C ratio, HOMA-IR indexes, serum asymmetric dimethyl arginine (ADMA), high sensitivity C-reactive protein (CRP), parathyroid hormone (PTH), calcium, phosphorous, estimated glomerular filtration rate (eGFR), and albumin levels were measured. Flow mediated vasodilatation (FMD) of the brachial artery was assessed by using high-resolution ultrasonography. RESULTS: A total of 11 cardiovascular (CV) deaths and 43 nonfatal CV events were registered in a mean follow-up period of 30 (range 9 to 35) months. Subjects with TG/HDL-C ratios above the median values (>3.29) had significantly higher plasma ADMA, PTH, and phosphorous levels (p=0.04, p=0.02, p=0.01 respectively) and lower eGFR and FMD values (p=0.03, p<0.001 respectively). The TG/HDL-C ratio was an independent determinant of FMD (ß=-0.25 p=0.02) along with TG, HDL-C, hsCRP, serum albumin, phosphate levels, systolic blood pressure, PTH, eGFR and the presence of diabetes mellitus. The TG/HDL-C ratio was also a significant independent determinant of cardiovascular outcomes [HR: 1.36 (1.11-1.67) (p=0.003)] along with plasma ADMA levels [HR: 1.31 (1.13-1.52) (p<0.001)] and a history of diabetes mellitus [HR: 4.82 (2.80-8.37) (p<0.001)]. CONCLUSION: This study demonstrates that the elevated TG/HDL-C ratio predicts poor CVD outcome in subjects with CKD. Being a simple, inexpensive, and reproducible marker of CVD risk, the TG/HDL-C ratio may emerge as a novel and reliable indicator among the many well-established markers of CVD risk in CKD. SYSTEMATIC REVIEW REGISTRATION: Clinical trial registration number and date: NCT02113462 / 10-04-2014.

Endocan, a novel marker of endothelial dysfunction in patients with essential hypertension: comparative effects of amlodipine and valsartan.

Vascular inflammation plays an important role in the pathophysiology of hypertension and high levels of endocan may reflect ongoing vascular inflammation in hypertensive patients. In the present hypothesis-generating study, we aimed at investigating the comparative effects of amlodipine and valsartan on endocan levels in newly diagnosed hypertensive patients. The study population consisted of 37 untreated hypertensive patients who were randomized to the two treatment arms. After baseline assessment, each patient was randomly allocated to either 10 mg daily of amlodipine (n = 18, 7 males) or 160 mg daily of valsartan (n = 19, 3 males) and treated for a 3-month period. Sphygmomanometric blood pressure (BP) and serum endocan were measured before and every 2 weeks during drug treatment. There was no statistically significant difference between the two treatment arms as far as baseline socio-demographic and clinical characteristics are concerned. After a 3-month treatment period, systolic and diastolic BP values significantly reduced by antihypertensive treatment (p < 0.001). Furthermore, endocan levels were significantly decreased in both treatment arms (p < 0.05). However, amlodipine caused a greater percent decrease in circulating endocan levels compared with valsartan at the end of the treatment period. Both drugs reduced high sensitivity C-reactive protein values. However, the statistical significant difference vs baseline was achieved only in the group treated with amlodipine. No correlation was found between endocan plasma levels and BP reduction. The results of this hypothesis-generating study suggest that amlodipine and valsartan decrease endocan levels in newly diagnosed hypertensive patients. The effects, which are more evident with amlodipine, may contribute to the anti-inflammatory effects exerted by the two drugs on the vascular target.

Ramipril lowers plasma FGF-23 in patients with diabetic nephropathy.

BACKGROUND/AIMS: Ramipril attenuates renal Fibroblast growth factor-23 (FGF-23) expression, ameliorates proteinuria and normalizes serum phosphate in the diabetic Zucker rat with progressive renal disease suggesting that the renoprotective effect by this drug may be in part due to a FGF-23-lowering effect of angiotensin-converting enzyme (ACE) inhibition. METHODS: In this nonrandomized study, we tested whether ACE-inhibition reduces circulating FGF-23 in type-2 diabetics with stage-1 chronic kidney disease (CKD) and proteinuria. Intact FGF-23, the eGFR, proteinuria and the endothelium-dependent flow-mediated (FMD) response to ischemia and other parameters were measured at baseline and after 12-weeks of treatment with ramipril (n = 68) or amlodipine (n = 32). RESULTS: Blood Pressure (BP) fell to a similar extent (p < 0.001) in the two groups. However, 24 h proteinuria and the FMD improved more (both p < 0.01) in ramipril-treated patients than in amlodipine-treated patients. Changes in proteinuria (r = 0.47) and in FMD (r = -0.49) by ramipril were closely associated (p < 0.001) with simultaneous changes in FGF-23 and this link was confirmed in multiple regression analyses. In these analyses, the relationship between FMD and proteinuria changes attained statistical significance (p < 0.01) only in a model excluding FGF-23 suggesting that endothelial dysfunction and FGF-23 share a common pathway conducive to renal damage. CONCLUSION: Findings in this study contribute to generate the hypothesis that FGF-23 may be implicated in proteinuria and in endothelial dysfunction in diabetic nephropathy (clinicaltrials.gov (NCT01738945)).

Mitral annular calcification and the serum osteocalcin level in patients with chronic kidney disease.

OBJECTIVE: To determine the relationships between inflammatory mediators, mitral annular calcification (MAC), and osteocalcin in patients with chronic kidney disease (CKD). MATERIALS AND METHODS: Echocardiographic data for 60 patients diagnosed as CKD were retrospectively evaluated. The patients were divided into 2 groups; patients with MAC (MAC+ group) and patients without MAC (MAC- group). The relationships between biochemical markers-including osteocalcin-and MAC were evaluated. RESULTS: The study included 19 female and 41 male patients. In all, 29 patients were MAC+ and 31 were MAC-. High-sensitive C-reactive protein (hsCRP) and osteocalcin levels were significantly higher in the MAC+ group (p < 0.05). The eGFR was lower, serum calcitonin (we could not obtain calcitonin data for 15 patients), Ca, PO4, CaxPO4, the erythrocyte sedimentation rate, red cell distribution width, the neutrophil/Lymphocyte rate, and PTH were higher in the MAC+ group; however, the differences between the groups were not significant (p > 0.05). The mitral E/A ratio, mitral peak Ea velocity, tricuspid E/A ratio, hsCRP, and the osteocalcin level were strongly correlated with MAC. Multivariate logistic regression analysis showed that only the osteocalcin level and mitral E/A ratio were independent variables, each with an independent effect on MAC. CONCLUSION: CKD patients in the MAC+ group had higher osteocalcin levels than those in the MAC- group, and left ventricular diastolic dysfunction was more common in the MAC+ group.

Neutrophil to lymphocyte ratio independently predicts cardiovascular events in patients with chronic kidney disease.

BACKGROUND: Increased inflammation is common in patients with chronic kidney disease (CKD) and is associated with increased adverse cardiovascular events (CVE). Neutrophil-to-lymphocyte ratio (NLR) was used to predict survival in patients with acute coronary syndrome. We aimed to evaluate predictive ability of NLR in CKD patients. METHODS: 225 subjects with stage 3-5 CKD were followed for a mean of 39 months. Fatal and nonfatal CVE were recorded during this period. NLR at baseline was determined from complete blood count differential. Endothelial dysfunction (flow-mediated dilation, FMD), hsCRP and insulin resistance were determined. We investigated if NLR could predict development of fatal and nonfatal CVE. We also looked at how NLR and its individual components change across CKD stages and whether NLR is related to CRP, insulin resistance and endothelial dysfunction. RESULTS: There were 70, 74 and 81 patients in groups of CKD stage-3, stage-4 and stage-5, respectively. Median NLR was 2.81. NLR showed a significant increase from stage 3 to stage 5. NLR was inversely associated with FMD independent of hsCRP. 14 fatal and 52 nonfatal CVE occurred during follow-up period. NLR could predict composite CVE independent of insulin resistance and hsCRP. Increased NLR over 2.81 was related to a significantly decreased survival time (log-rank Chi-square = 14.833, P < 0.0001). A cutoff value for NLR ≥3.76 could predict development of composite CVE with 80.3 % sensitivity and 91.8 % specificity. CONCLUSIONS: NLR is independently related to endothelial dysfunction and could predict composite cardiovascular endpoints independent of traditional confounding factors in patients with moderate to severe CKD.

Systemic involvements and preferred treatments in a large cohort of Behçet's disease.

The immunosuppressive drugs are widely used in systemic involvements of Behçet's disease. This study is aimed to investigate the extent of clinical involvement and preferred treatment approaches for type of involvements in Behçet's patients from the whole country. All patients with the diagnosis of Behçet's disease were enrolled to the study. These patients analyzed whether they fulfill the International Study Group Criteria, and only those were further evaluated. Demographic and clinical characteristics, laboratory results and treatments ever used were recorded. Further analysis is done regarding clinical manifestations and preferred therapeutic approaches. A total of 863 patients with the diagnosis of Behçet's disease were detected, but 682 of them (female/male: 113/569) found to be appropriate for analysis. The remaining patients were included to the analysis. The frequencies of articular, ophthalmic and vascular involvement were 49, 43 and 21 %, respectively. Colchicine and corticosteroids were the most preferred agents. The immunosuppressive agents frequently used for organ involvements were azathioprine, cyclosporine A, interferon-α, sulphasalazine and cyclophosphamide with decreasing order of frequency. In this relatively young population composed from all over the country, the frequency of ophthalmologic, venous and neurological involvement is less frequent than previous reported cohorts. Azathioprine and cyclosporine were the drugs of choice as a chronic immunosuppressive agent in patients with organ involvement. The previously reported increased frequencies in other cohorts could be a result of the reference of severe patients to dedicated centers.

The relationship between some of the cardiovascular risk factors and arterial stiffness parameters in essentially hypertensive patients.

Hypertensive patients have strong evidence of endothelial dysfunction. We aimed to explore the relationships between cardiovascular risk factors and arterial stiffness parameters in hypertensive patients. The study population included 109 hypertensive patients (63 females, 46 males). Arterial stiffness measures including pulse wave velocity, augmentation index, and central aortic pressure were applied. Augmentation index and central aortic pressure were found to be significantly higher (P < .001 and P = .03, respectively) in women. The higher augmentation index and central aortic pressure values were observed in women than in men. These data offer new evidences for the role of sex hormones in the pathogenesis of atherosclerosis in women.

Skinfold thickness as a predictor of arterial stiffness: obesity and fatness linked to higher stiffness measurements in hypertensive patients.

Hypertensive patients have strong evidence of endothelial dysfunction. Some novel endothelial dysfunction parameters such as pulse wave velocity (PWV), augmentation index (AIx), and central aortic pressure (CAP) have been investigated as predictive markers of atherosclerosis. It is well known that obesity has relationships with endothelial dysfunction and atherosclerosis. We aimed to investigate relationships between anthropometric measurements and arterial stiffness parameters in essentially hypertensive patients. The study population included 100 patients (56 females, 44 males) newly or formerly diagnosed as essentially hypertensive in an outpatient clinic. Arterial stiffness measurements, including PWV, AIx, CAP, and body mass index (BMI); waist circumference, hip circumference; waist/hip ratio; and triceps, biceps, subscapular, and suprailiac skinfold thicknesses were also applied to all the study patients. Then, the relationships between BMI, anthropometric measurements, and arterial stiffness parameters were investigated. The mean systolic arterial blood pressure of the study population was 135.85 ± 15.27 mm Hg and the mean diastolic arterial blood pressure of the study population was 84.17 ± 9.58 mm Hg. The parameters such as PWV, AIx, and CAP measured for arterial stiffness had correlations between BMI and different anthropometric measurements. The statistically significant correlations were present between PWV and triceps skinfold thickness (TST) (r = 0.377, P < .001) and it was also seen when regression analysis was performed (PWV = 6.41 + [0.072 × TST]; R(2) = 0.142, F[1-98] = 16.23, P < .001). Triceps skinfold thickness among these correlations may be used to estimate the carotid-femoral PWV, which is an indicator of subclinical organ damage due to hypertension.

The relationship between microalbuminuria, left ventricular hypertrophy, retinopathy, and sex hormone status in newly diagnosed hypertensive women.

An increased incidence of hypertension (HT) in postmenopausal female population has been shown in previous studies and this has been ascribed to an association with altered status of estrogen (E2) and other female sex hormones. Hypertension is associated with certain target organ damage (TOD) and related clinical conditions. The aim of this study was to determine the relationship between microalbuminuria, left ventricular hypertrophy (LVH), retinopathy, and sex hormone status in newly diagnosed hypertensive women. A total of 66 hypertensive women (39 postmenopausal and 27 premenopausal) were included in the study. Along with the tests recommended in the HT guidelines, LVH, hypertensive retinopathy, and microalbuminuria were investigated in all the patients. Sex hormones (follicle stimulating hormone, luteinizing hormone, progesterone, and E2) of the patients were also measured. The results show that there was no statistically significant difference between the two groups in regard to TOD except microalbuminuria. The frequency of microalbuminuria in premenopausal group patients was higher than that of the postmenopausal group patients (P = .038). This study suggests that TOD caused by HT is a very important health problem, seeming to be related with female sex hormones.

Investigation of the aortic pulse wave velocity in patients with Gilbert's syndrome.

Arterial stiffness is currently the "gold standard" measure of aortic (carotid-femoral) pulse wave velocity (PWV), which is an important independent predictor of risk of developing a cardiovascular event. Gilbert's syndrome is a congenital disorder characterized by intermittent and non-hemolytic elevation of indirect bilirubin levels due to the deficiency of the enzyme UDP-glucuronyl transferase in the liver and many prospective studies found an inverse relationship between bilirubin levels and cardiovascular events in these patients. We aimed to investigate serum bilirubin levels and arterial stiffness parameters in patients with Gilbert's syndrome in this study. A total of 53 cases, consisting of 26 patients with a diagnosis of Gilbert's syndrome and 27 healthy control subjects, were included in the study. Serum bilirubin levels, other routine blood chemistry, and arterial stiffness measurements were recorded. The mean ages of Gilbert's syndrome and the control group were 31.5 ± 9.7 and 36.8 ± 11.1 years, respectively. PWV measurements were significantly lower in Gilbert syndrome patients (6.68 and 7.3 m/s in patients and controls; respectively) (P < .05). In correlation analysis in Gilbert's syndrome patients, PWV had a significant correlation with total and indirect bilirubin levels (r = -0.370, P = .009/r = -0.495, P = .003, respectively). Gilbert's syndrome patients have lower PWV measurements compared to healthy subjects, and the total and indirect bilirubin levels are also associated with PWV measurements. These findings may indicate the decreased atherosclerotic disease incidence in Gilbert's syndrome patients.

The comparative effects of valsartan and amlodipine on vascular microinflammation in newly diagnosed hypertensive patients.

Pentraxin 3 (PTX3) is a new candidate immunoinflammatory marker that has been reported to be associated with cardiometabolic risk factors. We aimed to investigate the effects of valsartan and amlodipine on the PTX3 and C-reactive protein (CRP) levels in patients with essential hypertension. Patients with a newly diagnosed essential hypertension were admitted to our internal medicine outpatient clinic. Patients were randomized to one of the following intervention protocols: calcium channel blocker (amlodipine, 5-10 mg/day) as group A (n = 22; mean age ± standard deviation [SD]: 52 ± 11 year) and angiotensine II receptor blocker (valsartan, 80-320 mg/day) as group B (n = 28; mean age ± SD: 50 ± 14 year). Endothelial dysfunction and systemic inflammation were evaluated with PTX3 and CRP. There was a significant decrease in the level of PTX3 after treatment in two groups (P < .05). Although there was a significant decrease in the level of CRP after treatment in amlodipine group, there was no significant decrease in the levels of PTX3 and CRP after treatment in two groups. There were no significant differences in the systolic and diastolic blood pressure reduction between the two treatment groups. In the treatment of hypertension, prior knowledge of the level of plasma PTX3 could be important in antihypertensive drug choice. C-reactive protein and PTX3 are the markers that have role in vascular inflammation and are found associated with the prognosis of cardiovascular outcomes in many trials. In our study, PTX and CRP levels were decreased when compared to baseline levels.

The comparative effects of valsartan and amlodipine on vWf levels and N/L ratio in patients with newly diagnosed hypertension.

High levels of circulating Von Willebrand factor (vWf) and increased neutrophil to lymphocyte (N/L) ratio may reflect vascular inflammation in hypertensive patients. In present study, we aimed to investigate the effects of valsartan as an angiotensin II receptor antagonist and amlodipine as a calcium channel blocker on the vWf levels and N/L ratio in patients with essential hypertension. Patients were randomized to one of the following intervention protocols: calcium channel blocker (amlodipine, 5-10 mg/day) as group A (n = 20 mean age = 51.85 ± 11.32 y) and angiotensine II receptor blocker (valsartan, 80-320 mg/day) as group B (n = 26 mean age = 49.12 ± 14.12 y). Endothelial dysfunction and vascular inflammation were evaluated with vWf levels and N/L ratio in hypertensive patients before treatment and after treatment in the 12th week. No statistically significant differences were found among the groups in terms of age, sex, and body mass index (BMI). There was a significant decrease in vWf levels (P < .001) and N/L ratio after treatment (P = .04, P < .001, respectively) in both the groups. Von Willebrand factor levels and N/L ratio are very important markers having a role in vascular inflammation and antihypertensive treatment with amlodipine and valsartan may improve cardiovascular outcomes by decreasing these biomarkers.

An additional LDL-lowering effect of amlodipine; not only an antihypertensive?

Hypertension is a modifiable risk factor for cardiovascular diseases and is associated with several metabolic disorders like dyslipidemia. Higher levels of triglyceride and low-density lipoprotein (LDL) are quite strong factors for the development of cardiovascular diseases. In this study, we investigated the effects of valsartan and amlodipine on the lipid profile in patients with newly diagnosed essential hypertension. We observed a beneficial effect of amlodipine on the lipid profile with a significant reduction of LDL compared to valsartan. In the treatment of hypertension, prior knowledge of the plasma cholesterol levels can be important in antihypertensive drug choice.

Amlodipine seems to be superior to valsartan in decreasing microalbuminuria in newly diagnosed hypertensive patients: a novel effect to be explained with hyperfiltration?

BACKGROUND: Microalbuminuria (MA) is common in hypertensive population and is a marker for endothelial dysfunction and a predictor of increased cardiovascular risk. A great body of data shows the importance of MA as a strong predictor of renal and cardiovascular disease (CVD) risk in hypertensive population. AIM: In this study, we aimed to compare the anti-albuminuric effects of an angiotensin II receptor antagonist, valsartan, with a calcium channel blocker, amlodipine, in newly diagnosed hypertensive patients. MATERIAL AND METHODS: Totally, 20 patients were recruited into the study. Patients were randomized to one of the following intervention protocols: An (a) angiotensin II receptor blocker (valsartan, 80-320 mg/day) or (b) calcium channel blocker (amlodipine, 5-10 mg/day), for 12 weeks immediately after baseline measurements. Ten patients were randomized into valsartan group and 10 patients into the amlodipine group. Twenty-four-hour urinary albumin excretion (UAE) levels of the patient groups were measured before treatment and on the 12th week. RESULTS: Patients of the two groups were matched for age and body mass index. In the amlodipine group, baseline urine microalbumin levels were higher compared to valsartan group, although the difference was not statistically significant (p = 0.082). At the 12th week, there was a significant decrease in urine microalbumin levels in the amlodipine group, but no significant change was observed in the valsartan group. CONCLUSION: Amlodipine seems to be superior to valsartan in decreasing UAE. To reduce cardiovascular risks, endothelial dysfunction, and microinflammation, these factors are taken into consideration while prescribing antihypertensive drugs in hypertensive patients.
