The effect of low molecular weight heparin (LMWH) on serum lipid profile in hemodialysis remains controversial and its effect on bone metabolism has not been studied. A crossover study was conducted in 40 patients on stable hemodialysis using unfractionated heparin (UFH) for more than 24 months. These patients were then treated with a LMWH (nadroparin-Ca) for 8 months during hemodialysis and subsequently switched back to UFH for 12 months. Serum lipid profile, biochemical markers for bone metabolism, and bone densitometry (BMD) were monitored at four-month intervals while all medications remained unchanged. Cholesterol (TC), triglyceride (TG), low-density lipoprotein-cholesterol (LDL-C), lipoprotein(a) (Lp(a)), apolipoprotein B (Apo B) were raised in 35%, 29%, 12%, 24% and 24% of patients respectively. High-density lipoprotein-cholesterol (HDL-C) and apolipoprotein A1 (Apo A-1) were reduced in 47% and 9% of patients. Bone-specific alkaline phosphatase (BALP) and intact osteocalcin (OSC), both reflecting osteoblastic activity, were raised in 65% and 94% of patients. Tartrate-resistant acid phosphatase (TRACP) reflecting osteoclastic activity and parathyroid hormone (PTH) were elevated in 35% and 88% of patients. Following LMWH treatment, TC, Tg, Lp(a) and Apo B were reduced by 7%, 30%, 21% and 10% respectively (p<0.05 or <0.01) while Apo A-1 were raised by 7% (p<0.01). Simultaneously, TRACP was reduced by 13% (p<0.05). These biochemical changes were detected soon after 4 months of LMWH administration. Although BMD values in our patients were lower than those of age-matched normal subjects, significant changes were not observed with LMWH treatment. After switching back to UFH for hemodialysis, these biochemical indices reverted to previous values during UFH treatment with a significant higher level in TC and Apo B while serum Apo A-1 remained elevated. Our study suggests LMWH may partially alleviate hyperlipidemia and, perhaps, osteoporosis associated with UFH administration in patients on maintenance hemodialysis.

AbstractThe association between dyslipidemia and cognitive performance in Parkinson’s disease (PD) patients still needs to be clarified. Aim of the study was to evaluate the presence of possible associations between serum lipids fractions and executive dysfunction also exploring the sex-specific contribute of lipids level on cognition. Patients from the PACOS cohort, who underwent a complete serum lipid profile measures (total cholesterol-TC, low-density lipoprotein cholesterol-LDL, high-density lipoprotein cholesterol-HDL and triglycerides-TG) were selected. Adult Treatment Panel III guidelines of the National Cholesterol Education Program were used to classify normal/abnormal lipid fractions. Executive functioning was assessed with the Frontal Assessment Battery (FAB). Logistic regression was performed to assess associations between lipids fractions and FAB score. Correlations between lipids fractions and FAB score were explored. Sex-stratified analysis was performed. Three hundred and forty-eight PD patients (148 women; age 66.5 ± 9.5 years; disease duration 3.9 ± 4.9 years) were enrolled. Women presented significantly higher TC, LDL and HDL than men. In the whole sample, any association between lipid profile measures and FAB score was found. Among women, a positive association between hypertriglyceridemia and FAB score under cutoff was found (OR 3.4; 95%CI 1.29–9.03; p value 0.013). A statistically significant negative correlation was found between the FAB score and triglyceride serum levels (r = − 0.226; p value 0.005). Differently, among men, a statistically significant negative association between hypercholesterolemia and FAB score under cutoff (OR 0.4; 95%CI 0.17–0.84; p value 0.018) and between high LDL levels and FAB score under cutoff (OR 0.4; 95%CI 0.18–0.90; p value 0.027) were found. Our data suggest a sex-specific different role of lipids in executive functioning.

Background: Gallbladder disease is one of the most common gastrointestinal diseases. Various studies have shown association between gallstone and alteration in serum lipids. The objective of this study was to evaluate histological patterns of cholecystectomy specimens and compare serum lipid profile of gallstone patients with controls.Methods: This study was conducted over a period of two years (April 2016 to April 2018). Records of 287 specimens who underwent cholecystectomy were analysed in which gallstones were found only in 186 patients. Out of 186 patients with gallstones, records of serum lipid profile were available in 32 patients which were compared with 32 control of similar age. Independent t- test was used to compare the data between cases and control.Results: Out of 287 cases, 68 were male and 219 were female with male to female ratio of 1:3.2. The predominant histopathological lesion was chronic cholecystitis (73.17%). Malignancy was observed in 0.7% cases. Serum total cholesterol, triglycerides and low density lipoprotein cholesterol were found to be higher and statistically significant in patients with gallstone compared to controls (p value 0.024, <0.001and 0.016 respectively). Serum High density lipoprotein cholesterol was lower in gallstone patient than in control but not statistically significant (p value 0.23).Conclusions: Chronic cholecystitis was the most common histopathological lesion. Serum total cholesterol, triglyceride and low density lipoprotein cholesterol level were elevated and statistically significant in patients with gallstone.

Background/Aims: The study aimed to investigate the interactions of genetic variants in the leptin receptor (LEPR) gene with lipid profile changes following a high-carbohydrate/low-fat (HC/LF) diet in a Chinese Han population. Methods: Fifty-six healthy young subjects were given washout diets, followed by HC/LF diets consisting of 15% fat and 70% carbohydrate for 6 days. Serum lipid profiles and insulin levels before and after HC/LF diets were analyzed. Results: Statistically elevated high-density lipoprotein cholesterol (HDL-C), apolipoprotein A-1 (apoA-I), and insulin levels were only observed in the GG genotype of LEPR Lys109Arg but not in the A carriers after HC/LF diet. When gender was taken into account, significantly increased HDL-C, apoA-I, and insulin levels were found in women with the GG genotype. Moreover, lower low-density lipoprotein cholesterol (LDL-C) and higher insulin levels were only observed in subjects with the GG genotype of LEPR Gln223Arg, while higher HDL-C and apoA-I were only found in the A allele carriers. Additionally, the lower LDL-C and body mass index (BMI), and higher HDL-C and insulin levels were only observed in subjects with the GG genotype of LEPR Lys656Asn. Conclusions:LEPR polymorphisms contribute to the heterogeneities in BMI, LDL-C, and HDL-C responsiveness that are induced by a HC/LF diet in healthy young Chinese adults.

Introduction: In haemodialysis patients, mortality from cardiovascular disease is much greater than in the general population. The current study aimed to evaluate the effects of two different types of heparin, low molecular weight heparins (LMWH) and high molecular weight heparin (HMWH), on lipid profile in patients undergoing haemodialysis.Material & Methods: A total of 60 patients on haemodialysis were selected from two main hospitals of Lahore, Pakistan and were divided into two major groups based on the type of heparin used. A 5 ml blood sample was taken from the dialysis machine to get the serum and was kept frozen at -20ºC for analysis of total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein. Comparison of lipoprotein lipase activity between groups were evaluated by using the student t-test. A P-value of ? 0.05 was considered statistically significant.Results: Gender wise distribution of study population (n=60) was 67% (n=40) males and 33% (n=20) females. The age distribution of individuals varied from 39-43 years. Moreover, use of HMWH was high in males (73%) as compared to female (27%) with an average age of 39 ± 12 years where duration of haemodialysis was 4.44 ± 2.83. A significant difference in LPL activity related to different times in all patients was observed. A clearer difference observed in case of LDL where LPL activity was markedly different in both groups. Our data showed that individuals using LMWH had less chances of dyslipidaemia as compared to those using HMWH.Conclusion: LMWH is a useful and safe anticoagulant during haemodialysis as compared to HMWH.

AbstractThis study investigated the antihyperglycemic and antihyperlipidemic effects of low-molecular-weight carrageenan (LC) on rats fed a high-fat diet. Wistar rats were divided into five groups: normal control group (NC), high-fat diet control group (HC), carrageenan-treated control group (CC), 1% LC group (1% LC), and 3% LC-groups (3% LC). Body weight, food intake, fecal weight, blood glucose, and serum lipid levels were measured. After 30 days, body weight significantly decreased in the LC-treated groups than in the HC group. Moreover, in the LC-treated groups, postprandial blood glucose, total cholesterol, triglyceride, and low-density lipoprotein cholesterol (LDL-C) levels decreased, whereas high-density lipoprotein cholesterol (HDL-C) levels increased. From this study, our data suggest that LC has antihyperglycemic and hypolipidemic effects when compared to carrageenan, likely related to its increased absorption due to its lower molecular weight.

Kidney Rupture

For maintenance hemodialysis (MHD) patients, the blood is in low hypercoagulable state due to the use of heparin or low molecular weight heparin during dialysis. It is not rare to see hematoma in the puncture site. In recent years, several cases have been reported of spontaneous kidney rupture, but no hip hematoma, let alone both occurred in succession. There was one MHD patient with spontaneous kidney bleeding and hip hematoma in our hospital in 2014, and we provided effective treatment and follow-up.
