BackgroundLipoprotein-related mechanisms have been associated with damage to the cardiovascular system in diabetic patients. Apolipoprotein E gene which affects the clearance of lipoproteins and consequently the lipid profile in our body is one of the most studied candidate genes and recently has been reported to be associated with T2DM and CAD. In this work, we studied the association of apoE gene polymorphism with T2DM and CVD and its effect on plasma lipids profile.MethodsOur study was conducted on 284 subjects categorized into 100 patients with T2DM, 100 patients with T2DM complicated with CVD and 84 normal control subjects. ApoE gene polymorphism was genotyped by real-time PCR using TaqMan® SNP Genotyping Assay.ResultsApoE E3/E3 genotype was the most common in our subjects. The frequencies of E3/E4 genotype and ε4 allele were increased in both T2DM patients and CVD patients as compared with controls, but were significant only in CVD patients (p = 0.004 and 0.007, respectively). Diabetic patients who carried E3/E4 genotype were at 2.4-fold increased risk to develop CVD (95 % CI 1.14–5.19, P = 0.02) and the ε4 allele associated with 2.23-fold higher CVD risk (95 % CI 1.09–4.59, P = 0.02). After adjustment for other established risk factors, E3/E4 genotype was an independent risk factor for CVD (OR = 2.3, p = 0.009) but not for T2DM (OR = 1.7, p = 0.28), while ε4 allele was an independent risk factor for both T2DM (OR = 2.2, p = 0.04) and CVD (OR = 3.0, p = 0.018) with 5.9-fold increased risk to develop CVD in T2DM patients (p = 0.019). E3/E4 genotype associated with significantly higher levels of TC and non HDL-C in all groups and with significantly higher levels of LDL-C in both T2DM and CVD patients.ConclusionsApoE gene polymorphisms associate with CVD and affect the lipid profile. The ε4 allele is an independent risk factor for both T2DM and CVD. Further genetic studies to add information beyond the traditional cardiovascular risk factors in T2DM and to identify risk genotypes will help in early prediction and identification of at risk patients.

Objectives: This study was conducted to determine the association of insertion/deletion (I/D) polymorphism of the ACE gene in hypertensive and T2DM subjects in Egyptian population. Background: The deletion (D) allele of the angiotensin-converting enzyme (ACE) gene has been studied in relation to hypertension and type 2 diabetes mellitus (T2DM) with contradictory results which might be due to ethnic and geographical variations. Methods: A total of 85 subjects participated in this study; hypertension (Group 1); type 2 diabetes mellitus (Group 2) and controls (Group 3). Written informed consent was obtained. for each subject: age, sex, diabetes duration and the drugs used, blood pressure (systolic and diastolic), and lipid profi le. Genotyping was performed by polymerase chain reaction (PCR). Results: The frequency of DD genotype was signifi cantly higher in hypertensive (60 %) and diabetic patients (68 %) compared to controls (33.3 %) (p=0.04, p=0.01 respectively). The DD genotype (vs DI and II genotype) in the hypertensive and diabetic groups is associated with increased risk of hypertension and/or diabetes. OR=3.00; 95%, Cl = 0.993-9.067; OR=4.250; 95%, Cl = 1.234-14.63 respectively). The D allele was more frequent in hypertensive (77.5 %) and diabetic patients (82 %) compared to controls (52.4 %) (p=0.004 and 0.002 respectively). The D allele (vs the I allele) is associated with increased risk of hypertension and diabetes OR=3.13, 95%Cl=1.405-6.978; OR= 4.14, 95% CI= 1.615-10.622 respectively). Conclusion: The DD genotype and the D allele are associated with hypertension and type 2 diabetes in Egyptian patients (Tab. 5, Fig. 1, Ref. 32). Full Text in free PDF www.bmj.sk.
Plasma miR-126 and miR-210 levels may be biomarkers for diabetes with or without CAD.
Behcet's disease (BD) is a chronic relapsing multisystem disease of unknown etiology. Ethnic origin is one of the factors that may modulate the prevalence and the expression of BD. To study the clinical characteristics of Egyptian patients with BD, and compare the pattern of the disease in Egyptians with studies from other countries. Sixty-three patients with BD were studied over a 4-year period. A rheumatologist, dermatologist, neurologist and other specialists as indicated assessed the patients clinically. Laboratory and radiological examinations were done to confirm the diagnosis to rule out any condition that may mimic BD. Sixty-one patients were men, two were women, the mean age of the patients was: 32.8 +/- 8.3 years, age of onset of the disease varied between 17 and 37.4 years. The initial presenting manifestation was oral ulcers in 39.7% of patients, followed by orogenital ulcers in 23.8%, followed by deep venous thrombosis in 7.9% Throughout the study period, the commonest manifestation was oral ulcers (100%), followed by genital ulcers (96.8%), vascular lesions (57.1%), cutaneous (55.5%), ocular (47.6%), joint (36.5%), neurological (34.9%), gastrointestinal (19%) and cardiac (6.3%). BD in Egyptians shows higher male-to-female ratio and higher incidence of vascular and neurological lesions.
Insulin-like growth factor 1 (IGF-1) levels have been found to correlate with measurements of bone mineral density (BMD) in liver diseases. This study investigated the relationship between IGF-1, insulin-like growth factor binding protein 3 (IGFBP-3) and BMD in patients with chronic hepatitis C virus. This study was conducted for 30 patients with chronic hepatitis C virus infection (16 patients without and 14 patients with cirrhosis) and 11 healthy controls. Serum levels of IGF-1 and IGFBP-3 and BMD of the proximal femur and lumbar spine were measured in all subjects. Osteoporosis of the proximal femur and lumbar spine was found in 42.9% and 21.4%, respectively, of the patients with cirrhosis. Patients with liver cirrhosis and osteoporosis of the proximal femur and lumbar spine had lower IGF-1 (P<0.001, P=0.04, P=0.04 respectively). BMD of the proximal femur was lower in cirrhotic patients compared with controls (P<0.01). Patients with liver cirrhosis had lower IGFBP-3 than patients without cirrhosis and controls (P<0.001). Patients with osteoporosis of the proximal femur had lower IGFBP-3 than those without osteoporosis (P<0.01). IGF-1 and IGFBP-3 levels were lower in patients with liver cirrhosis. IGF-1 and IGFBP-3 may play a role in hepatic osteoporosis.
This study investigated the level of platelet malondialdehyde (MDA) as a marker of oxidative stress and coenzyme Q10 (CoQ10) as an index of antioxidant capacity in patients with type 2 diabetes mellitus and their relation to glycemic control. The study group consisted of 28 patients with type 2 diabetes mellitus (10 men and 18 women) with mean age of 48 +/- 2 years. Ten healthy individuals, age and sex matched with the patients, were used as a control group. Laboratory investigations in the form of lipid profile, glycosylated hemoglobin, plasma MDA, platelet MDA and plasma CoQ10 were assessed for all patients and controls. The study revealed that plasma and platelet MDA, as a marker of oxidative stress, were significantly higher in diabetic patients than in controls. The level of CoQ10, as antioxidant capacity, was significantly lower in diabetic patients than in controls. There was a negative correlation between plasma CoQ10 concentrations and glycosylated hemoglobin. Type 2 diabetic patients are at increased risk of oxidative stress manifested by increased plasma MDA as well as platelet MDA and decreased CoQ10, and this oxidative stress increases with poor glycemic control.
We assessed the dermatological manifestations associated with chronic hepatitis C virus (HCV) infection and their association with liver status. Of 155 patients with chronic HCV infection in Cairo, Egypt, 71 (45.8%) had dermatological manifestations: pruritus without evident skin lesions (21.3%), pigmented purpuric eruption (5.2%), aphthous ulcer and lichen planus (3.9% each), leukocytoclastic vasculitis (2.6%), psoriasis (1.9%), tinea versicolor (1.3%) and other conditions (5.8%). Shrunken liver, splenomegaly and ascites were significantly associated with the presence of skin lesions (relative risk 8.0, 2.7 and 1.8 respectively), and shrunken liver was significantly associated with pruritus (relative risk 2.1). Sex was not associated with any of the skin lesions.
