Aims: The aim of this study was to compare the risk factors and prevalence of vascular calcification (VC) in pre-dialysis and hemodialysis (HD) patients with Balkan endemic nephropathy (BEN) or other kidney diseases (non-BEN). Materials and Methods: The study involved 115 patients, 32 pre-dialysis and 83 HD patients, separated into groups of BEN and non-BEN patients. In addition to interviews, objective examinations and laboratory analyses, VC was assessed using Adragao score. Results: Patients with BEN were significantly older in both groups, while pre-dialysis BEN patients had significantly lower systolic blood pressure, serum cholesterol and phosphorus levels, but higher urinary excretion of phosphorus than non-BEN patients. These differences were lost in HD groups. In pre-dialysis patients, prevalence of VC was lower in BEN than in non-BEN group and mean VC score differed significantly between them (2.8 (1.7) vs. 4.6 (1.8); p = 0.009). No significant difference in VC score was found between BEN and non-BEN patients on HD. Multivariate analysis showed that in pre-dialysis patients VC score >4 was associated with lower iPTH and higher serum cholesterol level, but in the HD group with higher serum triglyceride level and longer HD vintage. Conclusions: Lower prevalence of risk factors for VC in the BEN than non-BEN patients was found in pre-dialysis but not in HD group and this was reflected in the prevalence and severity of VC in the groups. Prevalence of VC and mean VC score were significantly lower in pre-dialysis BEN than in non-BEN patients but not for those on HD.

Introduction. Vascular calcifications (VC) are common in patients with chronic kidney disease and present one of manifestations of mineral and bone disorders in these patients. Objective. The aim of this pilot study was to examine the prevalence and risk factors of VC in pre-dialysis patients with Balkan endemic nephropathy (BEN) and other kidney diseases. Methods. The study involved 32 pre-dialysis patients, 15 with BEN and 17 with other kidney diseases. All the patients underwent an interview, objective examination, routine laboratory analyses and measurement of serum concentration of intact parathyroid hormone (iPTH), 25-hydroxyvitamin D3 [25(OH)D3] and osteopontin. VCs in iliac, femoral, radial, and digital arteries were evaluated and Adragao VC score was calculated. The samples of radial artery were collected during the first creation of an arteriovenous fistula, and expression of osteocalcin, bone morphogenic protein-2 osteopontin, and matrix Gla-protein in arterial wall were examined. Results. Patients with BEN were significantly older (71.1 ? 6.1 vs. 54.7 ? 11.1 years), but they had significantly lower systolic and mean blood pressure (95.7 ? 13.2 mmHg vs. 104.3 ? 7.4 mmHg) and lower serum concentration of phosphorus (1.32 ? 0.36 mmol/l vs. 1.65 ? 0.35 mmol/l) and cholesterol (4.3 ? 1.1 mmol/l vs. 5.2 ? 0.8 mmol/l) than patients with other kidney diseases. Mean VC score was significantly lower in patients with BEN than in those with other kidney diseases (2.8 ? 1.7 vs. 4.6 ? 1.8; p = 0.009), but expression of four examined proteins in arterial wall differed insignificantly between the two groups. VC score correlated significantly with serum concentrations of cholesterol, triglycerides (positively), and iPTH (negatively). Conclusion. Pre-dialysis BEN patients had a significantly lower mean score of VC than patients with other kidney diseases.

Stroke is one of the foremost causes of morbidity, mortality and is a socioeconomic challenge. This is particularly true for developing countries like Bangladesh, where health support system including the rehabilitation system is not within the reach of common people. Hypertriglycerademia has an effective influence in the pathogenesis of Ischaemic Stroke (IS). So, the focus of this study was to evaluate and assess the association of serum triglyceride level in patients of IS. This case control study was carried out in the Department of Neurology in collaboration with Department of Biochemistry, BSMMU, Dhaka from July 2011 to June 2013. In this study, 60 diagnosed cases of ischaemic stroke patients and 60 age and sex matched healthy controls were enrolled. Risk factors of Ischemic Stroke (IS) patients were assessed ( adjusted Odds Ratio) in comparison with healthy adults. In this study, being married [OR. 1.95, 95% CI (0.40-9.42), p=0.409] , smoker [OR.1.65, 95% CI (0.57 - 4.82),p= 0.357], DM [OR. 1.48, 95% CI (0.36-6.06), p=0.582 ], IHD [OR. 1.51, 95% CI (0.29 – 7.89), p=0.624] , HTN [OR. 3.66, 95% CI (1.11–12.12), p=0.033] , overweight [OR.2.31, 95% CI (0.77 – 6.91), 0.135] and obesity [OR. 16.19, 95% CI (1.31–200.6), p=0.030] , increased level of serum TC [OR.8.24, 95% CI (2.07 – 32.83), p=0.003], TG [OR. 9.40, 95% CI (1.17 -75.86), p=0.035], LDL [OR. 0.45, 95% CI (0.10–2.05), p=0.308],and decreased level of HDL [OR. 3.37, 95% CI (1.03 - 12.25), p=0.045] were found as risk factors in developing IS. Independent t-test was done to find out the statistically significant differences of continuous variables like serum lipid profile between case and control group. The mean (SD) value of TG which is focus of this study, was found 237.67 (61.74) in case group, and 169.97 (26.95) in control group which was highly statistically significant (p < 0.0001). All of the significant variables were entered into stepwise logistic regression analysis model. From the logistic regression model, it can be finally concluded that hypertension, obesity, increased level of TC, increased level of TG and decreased level of HDL were statistically significant risk factors for development of IS.

Introduction: Intravascular calcification is thought to be a marker of atherosclerosis in patients with stenosis and vascular risk factors. Little is known about the utility of quantifying intracranial calcification to help determine mechanism of stenosis. The objective of our study was to compare presence and patterns of intracranial calcification in patients with intracranial stenosis due to atherosclerosis and other etiologies. Methods: Retrospective cohort study of 89 patients < 50 years with diagnosis of intracranial stenosis who had undergone CT angiogram from 2008-2013; 44 had presumed atherosclerosis as etiology ( > 3 vascular risk factors with no other identified cause). CTAs were reviewed for presence and location of intracranial calcification. Results: Of patients with atherosclerotic stenosis, 28 (64%) had intravascular calcification compared to 16 (36%) of those with stenosis of other etiologies (P=0.0039). There was no significant difference in pattern or location of stenosis between groups. One-third had calcification outside the region of stenosis in both groups. Distal internal carotid artery and distal vertebral artery were the most common sites of intracranial calcification (Table). Conclusion: Intracranial calcification is more commonly seen in patients < 50 years old with stenosis secondary to atherosclerosis, but the pattern and location was similar between groups. More research is needed to determine the utility of using the presence of vascular calcification to help determine mechanism of intracranial stenosis in the young.

Introduction Alterations in the lipid metabolism have been reported in the subject of diabetes mellitus. They may be influenced by the presence of hypertension. Aims The present study was undertaken to estimate the serum lipids profiles of diabetics with and without hypertension. Study design The study design is experimental with comparative study method, Methodology The sample size taken is 80 which is divided into four groups as A group of 20 healthy individuals of age 20-70 years, other B group of 20 diabetic patients without Hypertension, other C group of 20 hypertensive patients without diabetes and the rest 20 diabetic patients along with hypertension of age 20-70 years of D group. They were matched with respect to various lipid parameters such as total cholesterol, Triglycerides, lipoprotein ratio etc. with control group A. Place and duration of study: the study took place at Santosh group of institutions between August 2013 to August 2016. Result The serum cholesterol levels were significantly higher in hypertensives without diabetics and in diabetics with hypertension as compared to normal controls. No significant difference in the serum triglyceride level was observed among various groups in this study. The ?: ? lipoprotein ratio was found to be affected in all the groups as compared to controls with maximum ratio in diabetics without hypertension and in hypertension without diabetes. Patients who were suffering from diabetes and hypertension were at a maximum risk of developing atherosclerosisand its complications such as coronary artery disease. Diabetics with hypertension had significant higher levels of cholesterol as compared to that of without hypertension. The diabetics with hypertension had lipid abnormalities because of diabetic element in them rather than the hypertension. All the groups studied except the controls were found to be increasingly susceptible to the risk of atherosclerosis and its complications. This risk was found to be maximum in diabetics with hypertension rather than diabetics or hypertensive’s alone. Conclusion The need for right balanced diet, regular exercise and a stress free life is essential for prevention and management of diabetes and hypertension.

Abstract Background and Aims Calciphylaxis (CUA) is a rare but potentially fatal disease that is commonly occurred in dialysis patients. Since there is no data based on Chinese population, the study is aimed to investigate risk factors of CUA in Chinese hemodialysis patients. Method We retrospectively evaluated medical records of 20 hemodialysis patients who were newly diagnosed with CUA by skin biopsy admitted to Zhongda Hospital Southeast University from Oct.2017 to Dec.2018. Non-CUA dialysis patients with the same age and duration of dialysis were randomly selected as controls (Ratio=1:2). Results Most of CUA patients were male (80%) and elderly (55%), while 50% had a body mass index higher than 24. The mean time interval since start of dialysis to CUA diagnosis was 114.65±81.32 months, and the median time from appearance of skin lesion to diagnosis was 6 (2, 15) months. The incidence of hyperparathyroidism was higher in patients with CUA (80% vs 62.5%), but the differences of duration of elevated serum intact parathyroid hormone (iPTH) and its highest value were not significant compared with the controls. Warfarin therapy had no significant difference between two groups (15% vs 5%). Univariate logistic regression analysis indicated that male (OR 3.619, 95%CI 1.027-12.748), each 1 point increase in score of use of vitamin D and its analogues (OR 1.505, 1.029-2.201), each 1 mmol/L increase in corrected serum calcium level (OR 24.486, 1.570-381.873), each 1 mmol/L increase in serum phosphate level (OR 5.382, 1.767-16.389), each 1 pg/mL increase in iPTH level (OR 1.002, 1.000-1.003), each 1 g/L decline in serum albumin level (OR 1.181, 1.041-1.340), each 1 IU/L increase in serum alkaline phosphatase (ALP) level (OR 1.005, 1.000-1.009) and each 1 mg/L increase in hypersensitive c-reactive protein level (OR 1.029, 1.000-1.059) were significantly associated with CUA. Serum phosphate, albumin and ALP were still significant risk factors after multivariate analysis. Conclusion This is the first report of risk factors of CUA based on Chinese population. The results show that high levels of serum phosphate and ALP, low level of serum albumin are independent risk factors of CUA in Chinese hemodialysis patients. Unlike previous research from western countries, warfarin therapy didn’t show an increased risk in this study, propably because of the low exposure rate of it in China.

Edamame (Glycine max) is a preparation of immature soybeans in the pod, which is high in calcium and dietary fiber, two elements described in previous studies that could alter the level of post-prandial serum triglyceride.The purpose of this research is to analyze the effect of edamame (Glycine max) extract on post-prandial serum triglyceride in rats after intragastric administration of palm oil.The materials used in this study are palm oil, edamame extract, and ether. The design of this study is experimental post-test study design, which is a design to measure the serum triglyceride level after meal with and without Glycine max. Triglyceride is measured on each subject two times on total, first one after consumption of meal without Glycine max and the second one after consumption of meal with Glycine max. There is a washout period of 1 week between two times the samples were taken. Both results are then compared in every subject.The level of 2-hour post-prandial serum triglyceride in rats after palm oil without intragastric edamame (Glycine max) extract administration and with intragastric edamame (Glycine max) extract administration showed no significant difference. In conclusion, edamame (Glycine max) extract had no effect on 2-hour post-prandial serum triglyceride after palm oil administration via intragastric tube.

Abstract Background and Aims Vascular calcification (VC) is common sequelae in chronic and end-stage kidney diseases (CKD/ESKD), and is associated with multiple risk factors, including disturbed bone metabolism and mineral disorders (CKD-BMD), uremia, leading to increased morbidity and mortality. The mechanism involves multiple physiological processes and is not well understood. The study aims to develop a causal pathway-based physiological model describing patient-specific drivers of vascular calcification. Method We develop a causal pathway-based physiological modeling that utilizes clinical data to identify patients with high risks of progression of VC and cardiometabolic diseases to provide multifactorial intervention strategies targeting the risk factors. We investigate the response of pulse pressure (PP, a proxy for pulse wave velocity) to parathyroid hormones (PTH), calcium (Ca), phosphate (PO4), calcium-phosphate product (CaPO4), neutrophil-lymphocyte ratio (NLR), and albumin (Alb). Pulse pressure may account for both cardiac and vascular conditions (e.g., atrial fibrillation, aortic insufficiency, arterial stiffness or arteriovenous malformation, aortic valve stenosis, cardiac insufficiency or cardiac tamponade). Results We demonstrate the causal pathway of PTH, Ca, PO4, NLR, and Alb on PP, and find that there are likely paths from PTH, Ca, PO4, CaPO4, NLR to PP, where the strength of the relationships vary from patient to patient. Figure 1 shows a representative patient. Figure 1(a) shows the longitudinal data for the aforementioned clinical parameters. Using a subset of the data (1 year was used), we extracted causal relationships between the clinical (Fig. 1(b)). As shown in Fig. 1(c), some of the relationships are physiologically consistent with current knowledge of the PTH, Ca, and PO4 disturbances on CKD-BMD, vascular calcification being one of the axes. Also, NLR is a measure of inflammation, which is also known to promote vascular calcification. Further, potential pathways were also detected, namely the direct or mediated effects of Alb and PTH on PP (as shown in Figs. 1(b)-(c)). Using these pathways, a dynamic model describing these interactions can be used to prescriptive investigate the impact of the dynamics on the progression of calcification. Conclusion From the clinical variables, the method was able to extract both known and potential drivers for changes on PP for the representative patients. Additional study is needed to confirm these relationships both prospectively, clinical investigation of potential pathways, and to further observe the long-term clinical manifestation of vascular calcification.

Preeclampsia is one of the most important pregnancy disorder, diagnosed with hypertension and proteinuria. It is the leading cause of fetal and maternal morbidity and mortality. This cross-sectional study was conducted in 100 pregnant women, of them, 50 were diagnosed cases of preeclampsia and 50 were normal pregnant women attended in the Gynaecology and Obstetrics department of Dhaka Medical College Hospital, Dhaka, during July 2016 to June 2017. Five ml fasting blood sample was collected and was analysed for triglyceride using standard enzymatic method. Mean value of triglyceride was compared between two groups by student unpaired t-test and the triglyceride level was correlated with systolic, diastolic blood pressure and urine albumin in preeclamptic patient was correlated by Pearson's correlation coefficient test. A p-value was considered to be statistically significant at 0.05 at 95% confidence interval. Statistically significant difference of serum triglyceride level was found in preeclamptic women and normal pregnant women (p<0.05). The level was 248.90±31.36 mg/dl in preeclampsia and 197.00±27.04 mg/dl in normal pregnant women respectively. Serum triglyceride was positively correlated with systolic, diastolic blood pressure and urine albumin in preeclamptic women. Faridpur Med. Coll. J. Jul 2019;14(2): 82-85

Abstract: In general, obesity is associated with a decrease of blood HDL-cholesterol level and an increase of serum triglyceride level. In obese people, the  triglyceride is deposited in the subcutaneous layer of the skin. This triglyceride plays an important role in the formation of VLDL and LDL-cholesterol in the liver which will be released into the blood. This was an observational study with a cross-sectional design. Samples were 22 obese female students and 22 non-obese female students of Faculty of Medicine, University of Sam Ratulangi Manado aged 18-22 years. The results showed that the mean HDL-cholesterol levels in obese females was 57.64 mg/dL, meanwhile of the non-obese females was 61.77 mg/dL. Albeit, the statistical analysis showed no significant difference between the HDL-cholesterol levels of obese and non-obese females (P-value 0.974). Conclusion: There was no significant difference between the HDL-cholesterol levels of obese females and non obese females. Keywords: HDL-cholesterol levels, females, obese, non obese     Abstrak: Obesitas berhubungan dengan penurunan kadar kolesterol HDL darah dan peningkatan kadar serum trigliserida.3 Pada individu obes, trigliserida disimpan pada jaringan subkutan. Trigliserida itu merupakan bahan utama pembentukan VLDL dan LDL di hati yang akan dilepaskan ke dalam darah. Penelitian ini bersifat observasional dengan menggunakan cross-sectional design. Sampel penelitian terdiri dari 22 mahasiswi Fakultas Kedokteran Universitas Sam Ratulangi yang obes dan 22 mahasiswi yang non-obes. Hasil penelitian memperlihatkan bahwa rerata kadar kolesterol HDL pada sampel yang obes 57,64 mg/dL dan pada yang non-obes 61,77 mg/dL. Uji statistik memperlihatkan tidak terdapat perbedaan bermakna antara kadar kolesterol HDL darah pada wanita yang obes dan yang non-obes (P = 0,974). Simpulan: Tidak terdapat perbedaan bermakna antara kadar kolesterol HDL darah pada wanita obes dan wanita non-obes. Kata kunci: kadar kolestrol HDL, wanita, obes, non-obes.

Background/Aim. It has been proved that a highly sensitive C-reactive protein (hsCRP) can be used as an established marker of chronic inflammation for cardiovascular risk assessment. Since mean values of both low-density cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) decrease during aging, the knowledge that increased hsCRP concentration predicts mortality (Mt) would influence therapy and treatment outcome. The aim of this study was to examine importance of chronic low grade inflammation and its association with lipid risk factors for all-cause Mt in functionally dependent elderly. Methods. The participants of this longitudinal prospective study were 257 functionally dependent elderly aged 65-99 years. Baseline measurements: anthropometric measurements, blood pressure, fasting plasma total cholesterol (TC), triglyceride (TG), HDL-C, LDL-C, non- HDL-C, hemoglobin A1c (HbA1c) were recorded and different lipid ratios were calculated. Inflammation was assessed by the levels of white blood cells, fibrinogen and hsCRP. The participants with hsCRP grater than 10 mg/L were excluded from the study. The residual participants (77.4% women) were divided into three groups according to their hsCRP levels: a low (< 1 mg/L, n = 70), average (1 to 3 mg/L, n = 69), and high (3-10 mg/L, n = 69) hsCRP group. Associations of all-cause Mt with different risk factors were examined using logistic regression analysis. Results. The hsCRP level showed a significant positive correlation with waist (r = 0.199, p = 0.004) and hip (r = 0.187, p = 0.007) circumferences, body mass index (r = 0.143, p = 0.040) and serum triglyceride level (r = 0.139, p = 0.045) and significant negative correlation with HDL-C (r = -0.164, p = 0.018). Ratios TC/HDL-C and TG/HDL-C were significantly smaller in the low hsCRP group compared to the average hsCRP group (p = 0.019, p = 0.045, respectively) and without significant differences compared with the high hsCRP group. Two years after the baseline examination 22.1% participants died from all-cause Mt. After adjustment for other risk factors, a TC was significantly associated with all-cause Mt only in high hsCRP group: Odds ratio (OR) = 3.71 (95% confidence interval-CI : 1.09-12.63). Conclusions. In this study a high hsCRP was an important factor to identify functionally dependent elderly at high risk who may have more benefit from agressive lipid lowering treatment.
