DM-related dyslipidemia are associated with complications resulting from progressive damage of various organs. CD36 is 88-kD, class B scavenger receptor, expressed on different types of cells. In diabetic patients, LDL particles are glycated with strong level;this increases CD36 expression, initiates foam cell formation and accelerates atherosclerosis. Objective: This study aimed to determine the correlation between serum CD36 level and lipid profile among patients with type 2 diabetes mellitus in Zeenam Specialized center, Khartoum State, Sudan, in a period between 2019 and 2022. Methodology: Hundred participants at different ages were included in this study;70 were type 2 diabetic patients (cases) and 30 apparently healthy individual (control). 3 ml of venous blood were collected from the participants by using a sterile needle and syringe into a labeled plain container. Each sample was stood until complete clot occurs. Clotted blood sample was then centrifuged to obtain the serum. Then they were used for measurement of total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride and soluble CD36 levels. Total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were measured using Biosystem chemistry analyzer BTS-302. Serum CD36 was measured using Microplate Reader (URIT-660). Results: The results revealed that serum total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels were significantly higher in patients with type 2 diabetes mellitus compared with control (P = 0.03, P = 0.031, P = 0.000, P = 0.000) respectively, while there is no statistically significant differences in serum CD36 level between cases and control (P = 0.129). Also this study showed that there is no statistically significant correlation between serum CD36 level and total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, age and body mass index. Conclusion: This study concluded that there is no statistically significant difference in serum CD36 level between cases and control. And sCD36 level was not correlated with total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, body mass index, and age.展开更多

Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) and apolipoprotein(Apo) AI were lower in Bai Ku Yao than in Han(P【0.01 for all).The frequency of A and G alleles was 98.00%and 2.00%in Bai Ku Yao,and 95.20%and 4.80%in Han(P【0.01);respectively. The frequency of AA,AG and GG genotypes was 95.99%,4.01%and 0%in Bai Ku Yao,and 91.02%, 8.36%and 0.62%in Han(P【0.01);respectively.There were also significant differences in the genotypic and allelic frequencies between n and the ratio of ApoAI to ApoB in Han Chinese but not in Bai Ku Yao were different between the AA and AG/GG genotypes(P【0.05 for all).The G allele carriers had higher serum HDL-C and higher ApoAI to ApoB ratio than the G allele noncarriers.When serum lipid parameters in Han were analyzed according to sex,the G allele carriers had higher serum HDL and ApoAI levels in males (P【0.05),and lower ApoB level and higher ApoAI to ApoB ratio in females(P【0.05 for all).Multiple linear regression analysis showed that serum HDL-C levels were correlated with genotypes in both ethnic groups(P【0.05 each).Serum lipid parameters were also correlated with sex,age,body massindex,alcohol consumption,cigarette smoking,and blood pressure in both ethnic groups(P【0.05-0.001).Conclusions These results suggest that the PCSK9 E670G polymorphism is mainly associated with some serum lipid parameters in the Han population,both gender show different relations to different serum lipid parameters.The G allele carriers might have higher serum lipid profiles than the G allele noncarriers. ormal LDL-C(≤3.20 mmol/L) and high LDL-C subgroups (】 3.20 mmol/L,P【0.01;respectively) in Bai Ku Yao, and between normal ApoB(≤1.14 g/L) and high ApoB subgroups(】 1.14 g/L,P 【 0.01;respectively) in Han.展开更多
