Introduction: Diabetic nephropathy is a microvascular complication and is the leading cause of diabetes related morbidity, mortality and important cause of end-stage kidney disease. Both microalbuminuria and macroalbuminuria are associated with increased risk of cardiovascular disease. Evidence has been accumulating from clinical trials that assessing the levels of apolipoprotein B (ApoB), a constituent of atherogenic lipoproteins: ApoA1, a component of anti-atherogenic high density lipoprotein (HDL) cholesterol; and the ApoB/ApoA1 ratio will provide better prediction of future cardiovascular events than measuring serum low-density lipoprotein (LDL)-cholesterol levels. There is paucity of published data linking ApoB/ApoA1 ratio to diabetic nephropathy especially from developing countries, hence this study was carried out. Materials and Methods: The present study was conducted in the Department of Medicine, CSM Medical University, Lucknow between August 2009 and July 2010. Patients with type 2 Diabetes Mellitus (DM) attending the Diabetic and Medical Out-Patient clinics or who were admitted to the medical wards of Gandhi Memorial and Association Hospital CSM University, Lucknow were included. One hundred patients were enrolled; 64 of those were cases (Micro- and Macroalbuminuria groups) and 36 without nephropathy (Normoalbuminuria) were controls. The cut-off value for higher ApoB/ApoA1 ratio for male was 0.97 and for female was 0.86. Results: Older age, durations and control of DM were significantly correlated with degree of albuminuria. Fifty-six patients (56%) had raised ApoB/ApoA1 ratio, 19.4% in the Normoalbuminuria group (n=7/36), 71.4% in the Microalbuminuria group (n=30/42), and 86.4% in the Macroalbuminuria group (n=19/22). There were no statistical differences in the mean total cholesterol, HDL, LDL, triglycerides among the groups. Conclusion: In our study higher ApoB/ApoA1 ratio was significantly correlated with diabetic nephropathy.

BACKGROUND/AIMS: Changes in lipid profiles in patients infected with hepatitis C virus (HCV) during direct-acting antiviral therapy have been reported in recent years. However, the clinical aspects of disturbed lipid metabolism in chronic HCV infection have not been fully elucidated. METHODS: Dynamic changes in serum total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol and apolipoprotein levels in patients infected with HCV genotype 1b were examined during combination therapy with daclatasvir (DCV) and asunaprevir (ASV). RESULTS: Total, LDL−, and HDL-cholesterol levels increased rapidly and persistently after week 4. Apolipoprotein (apo) A-I, apo B, apo C-II, and apo C-III levels were significantly higher at week 4 than at week 0. In contrast, apo A-II and apo E levels were significantly lower. The differences in LDL− and HDL-cholesterol levels were positively correlated with those of apo B and apo A-I, respectively. Interestingly, in patients with non-sustained virological response, these cholesterol levels decreased rapidly after viral breakthrough or viral relapse. Furthermore, similar changes were observed for apo A-I, apo B and apo C-III levels. CONCLUSIONS: Clearance of HCV using combination therapy with DCV and ASV results in rapid changes in serum lipid profiles, suggesting an influence of HCV infection on disturbed lipid metabolism.

OBJECTIVETo explore the gene polymorphisms of ApoAI-75 Msp1, ApoB Msp1, ApoCIII Sst1, LRP5, and ApoE genotypes in two pairs of semi different modes of hepatitis B for HBV markers.

METHODSThe patients are divided into 9 groups. There were a total of 720 cases, 80 patients in each group, The patients was carried out by SnaPshot method (single-base multilocus micro-sequencing), and different genotypes of each locus were conducted by the method of sequencing in order to support the final evidence of the accuracy of test results.

RESULTSThere was association between gene polymorphisms of ApoAI-75Msp1 and ApoE and different modes of two pairs of semi-hepatitis B (P < 0.05), while there wasn't any association between gene polymorphisms of ApoB-Msp1, ApoCIII-Sst1, LRP5 and different modes of two pairs of semi-hepatitis B (P > 0.05).

CONCLUSIONThe gene polymorphism of ApoAI-75Msp1 and ApoE was associated with the different modes of HBV markers.

PURPOSE: Apolipoprotein E (Apo E) plays a major role in lipoprotein metabolism and lipid transport. Many investigators have described that Apo E polymorphisms is one of the most important genetic determinants for cardiovascular disease. The purpose of this study was to evaluate the association between Apo E polymorphisms and serum lipid profiles in obese adolescent. METHODS: We measured the serum concentrations of glucose, apolipoprotein (Apo) A1, Apo B, total cholesterol (TC), triglyceride (TG), HDL and LDL-cholesterol after overnight fasting in obese adolescent. Apo E polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: 86 obese adolescents participated in this study. The body mass index (BMI) of participants were excess of 95 percentile by age and sex. Male to female ratio was 1.7 and mean age of study group was 16.2+/-1.8 years. Mean BMI was 27.4+/-2.5 kg/m2. The frequency of epsilon2, epsilon3 and epsilon4 allele were 8.1%, 87.2% and 4.7% respectively. Study populations were classified into the following three genotypes 1) Apo E2 group (n=13, 15.1%) carrying either the epsilon2/epsilon2 or epsilon2/epsilon3 2) Apo E3 group (n=65, 75.6%) carrying the most frequent epsilon3/epsilon3 3) Apo E4 group (n=8, 9.3%) carrying either the epsilon3/epsilon4 or epsilon4/epsilon4. No differences were found among Apo E genotypes concerning age, sex, weight, height and BMI. Apo B and LDL-cholesterol concentrations were significantly higher in the Apo E4 group (P<0.05). No association were found between Apo E genotypes and glucose, Apo A1, TC, TG and HDL. CONCLUSIONS: We confirmed that serum concentrations Apo B and LDL-cholesterol were influenced by Apo E genotypes. Apo E polymorphisms seems to influence some alteration of lipid metabolism associated with obesity in adolescent.

BACKGROUND: CETP(Cholesteryl ester transfer Protein) is the essential protein for 'reverse cholesterol transport' which transfers cholesteryl ester from HDL particles to other lipoproteins. The subjects with CETP deficiency caused by genetic mutation in the CETP gene have very high HDL levels that CETP deficiency implies anti-atherogenic effect. A missense mutation in the exon 15(D442G) and a splicing defect in the intron 14(Int 14A) in the CETP gene are reported to be popular among Japanese population which overall prevalence of both mutations is up to 10%. METHODS: To identify the CETP mutaion such as D442G or Int 14A among Koreans, seven subjects who have high HDL level above 80mg/dl and 14 first-degree relatives of them were included in this study. RESULTS: Of 21 subjects in 7 familes, 5 subjects in 2 families were confirmed as D442G mutation of CETP gene, but Int 14A mutation is not found. Subjects with D442G mutation have high apo A-I levels as well as HDL levels. CONCLUSION: The D442G mutation of CETP gene is firstly confirmed in Koreans. The CETP deficiency caused by genetic mutation in the CETP gene seems to be prevalent among Korean population.

BACKGROUND AND OBJECTIVES: Apolipoprotein A-I is the major lipoprotein constituent of high density lipoprotein in plasma. In this study, the role of two polymorphisms in the apo A-I gene was investigated on the serum lipid profiles and apo A-I levels in healthy men and women. SUBJECTS AND METHODS: Blood samples were obtained from 417 subjects (M : F=169 : 248, mean age 47.2 years). The apo A-I genotypes were determined by SNP-IT assays using the SNPstream 25KTM system. RESULTS: The frequencies of the A allele at the XmnI restriction site and position -75 bp were 0.25/0.23 and 0.19/0.17 in men and women, respectively. A strong positive linkage disequilibrium (D'=0.990) between two polymorphisms was detected. In men, the A allele at the XmnI restriction site was associated with significantly lower levels of triglyceride (p=0.028) compared to the G/G subjects, but no significant associations were detected between the G-75A polymorphism and any of the lipid traits examined. In women, each A allele for the XmnI restriction site and -75 bp polymorphisms were significantly associated with higher levels of apo A-I (p=0.032 and p=0.012). In the multiple regression analysis, the HDL, being a current drinker and the A allele of the XmnI restriction site polymorphism were major determinants of the serum apo A-I levels in women (R2=0.272, p<0.05). CONCLUSION: Our study showed that the A allele at XmnI restriction site in the apo A-I gene was associated with decreased triglyceride levels in men. Each A allele of two polymorphisms was associated with an elevated apo A-I level in women.
