Type 2 Diabetic

Type 1 diabetes is recognized as an autoimmune inflammatory disease and low grade inflammation is also observed in type 2 diabetic patients. Interleukin 17 (IL-17) is a new player in inflammation. Th17 cells, as the main source of IL-17, require transforming growth factorβ(TGF-β) and interleukin 23 (IL-23). The aim of this study was to investigate serum IL-17, IL-23 and TGF-βlevels in diabetic patients and controls. In this case-control study, serum levels of IL-17, IL-23, and TGF-βwere measured in 24 type 1 diabetic patients and 30 healthy controls using the ELISA method. Simultaneously, the same methodology was used to compare serum concentration of these three cytokines in 38 type 2 diabetic patients and 40 healthy controls. There was no significant difference between serum levels of IL-17 and IL-23 cytokines between cases and controls. However, TGF-βwas significantly lower in type 1 diabetic patients (P<0.001). Serum IL-17 and IL-23 levels demonstrate no association with type 1 and type 2 diabetes, but, in line with previous studies, TGF-βlevels were lower in type 1 diabetic patients.

Background: High levels of homocysteine and oxidative stress are known to be associated with premature vascular disease in type 2 diabetes mellitus (DM). The aim of this study was to estimate homocysteine levels and oxidant-antioxidant status and to determine the relationship between them in type 2 diabetic patients with and without microalbuminuria. Methods: Fasting blood samples were obtained from 48 diabetic patients (17 with and 31 without microalbuminuria) and 20 healthy subjects. Serum total homocysteine (tHcy), plasma malondialdehyde (MDA) erythrocyte glutathione (GSH) and glutathione peroxidase (GPx) activity were measured in these patients and the results were compared with those of controls who were chosen among healthy subjects. Results: MDA levels were found to be significantly lower and GSH levels and GPx activities were found to be significantly higher in control subjects when compared with patients with and without microalbuminuria (MDA: P<0.0001, P<0.0001; GSH: P<0.0001, P<0.0001; GPx: P<0.0001, P<0.001, respectively). MDA levels were found to be significantly higher in patients with microalbuminuria compared with patients without microalbuminuria ( P<0.0001), while similarly GSH levels were found to be significantly lower in patients with microalbuminuria ( P<0.0001). Although there were no significant differences with respect to tHcy levels and GPx activities between the microalbuminuric and normoalbuminuric patients ( P>0.05), there was a significant difference with respect to tHcy levels between healthy controls and patients with microalbuminuria ( P<0.05). The serum levels of tHcy correlated best with plasma MDA and erythrocyte GSH concentrations in all diabetic patients ( r=0.549, P<0.0001; r=0.385, P<0.01). Conclusion: Decreased antioxidant levels, increased lipid peroxidation and increased tHcy levels were observed in patients with microalbuminuria. These changes may contribute to vascular disease, which is particularly prevalent in type 2 DM patients with microalbuminuria.

Abstract Background Insulin-like growth factor-I (IGF-I) is homologous to proinsulin and possesses glucose reducing activity. The association between the level of IGF-I and diabetes has been highlighted. However, this association is controversial due to the influence of different factors including obesity. The aim of the study was to evaluate serum level of IGF-I in type 2 diabetic patients compared to control subjects. Materials and methods A cross-sectional study involving 100 participants was conducted. Serum levels of IGF-I were measured using enzyme-linked immunosorbent assay (ELISA) and the fasting plasma glucose (FPG) levels were measured using the glucose oxidase method. Results IGF-I levels in the diabetic patients were significantly lower than in non-diabetic control subjects (105.13 ± 6.34 vs. 159.96 ± 9.62 ng/mL, p < 0.0001). Among the diabetic group, there was no significant difference in IGF-I levels between obese diabetic patients and non-obese diabetic patients, p = 0.18. Similarly, among the non-diabetic group, a non-significant difference was found in IGF-I levels between obese non-diabetic and non-obese non-diabetic subjects, p = 0.156. However, among the obese group, obese diabetic patients had significantly lower IGF-I serum levels compared to obese non-diabetic subjects (112.07 ± 7.97 vs. 147.07 ± 13.05 ng/mL, p = 0.02). Furthermore, among the non-obese group, the non-obese diabetic patients had significantly lower IGF-I serum levels compared to the non-obese non-diabetic subjects (91.66 ± 9.93 vs. 171.86 ± 13.86 ng/mL, p < 0.0001). No significant associations were observed between IGF-I level and any of the age, gender, body mass index (BMI), FPG levels, or the duration of diabetes. Conclusions Type 2 diabetes mellitus is associated with lower levels of IGF-I regardless to the presence or absence of obesity.

Aims. This study investigated the association of autoantibodies binding to oxidized low-density lipoproteins (oxLDL) in diabetic retinopathy (DR). Methods. Plasma from 229 types 1 and 2 patients with DR including diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR) was analysed with ELISA-based assay to determine IgA, IgG, and IgM autoantibody levels binding to oxLDL. The controls were 106 diabetic patients without retinopathy (NoDR) and 139 nondiabetic controls (C). Results. PDR group had significantly higher IgA autoantibody levels than DME or NoDR: mean 94.9 (SD 54.7) for PDR, 75.5 (41.8) for DME (p=0.001), and 76.1 (48.2) for NoDR (p=0.008). There were no differences in IgG, IgM, or IgA that would be specific for DR or for DME. Type 2 diabetic patients had higher levels of IgA autoantibodies than type 1 diabetic patients (86.0 and 65.5, resp., p=0.004) and the highest levels in IgA were found in type 2 diabetic patients with PDR (119.1, p>0.001). Conclusions. IgA autoantibodies were increased in PDR, especially in type 2 diabetes. The high levels of IgA in PDR, and especially in type 2 PDR patients, reflect the inflammatory process and enlighten the role of oxLDL and its autoantibodies in PDR.

Abstract Background: We assessed the ability of LDL from 30 type 1 diabetic patients (18 men, 12 women), 65 type 2 diabetic patients (35 men, 30 women), and 35 controls (19 men, 16 women) to generate peroxides. The men and women in the diabetic groups were studied separately and matched for age, body mass index, duration of diabetes, glycohemoglobin, and conventional lipid characteristics according to the presence or absence of hyperlipidemia. Methods: The ability of LDL to form peroxides was assessed by measuring the thiobarbituric acid-reactive substances corrected for LDL-cholesterol [ratio of malondialdehyde (MDA) to LDL-cholesterol]. LDL particle size was expressed as the ratio of LDL-cholesterol to apolipoprotein B (LDL-cholesterol/apoB). Results: The MDA/LDL-cholesterol ratio was higher in type 1 and type 2 diabetic patients with hyperlipidemia than in controls. The MDA/LDL-cholesterol ratio was also higher in type 2 normolipidemic women than in controls (P &lt;0.01). The LDL-cholesterol/apoB ratio was lower in type 2 diabetic women than in type 2 diabetic men (P &lt;0.05). The MDA/LDL-cholesterol ratio was negatively correlated with the LDL-cholesterol/apoB ratio (r = −0.78, P &lt;0.001) in hyperlipidemic type 1 (not type 2) diabetic patients. In normolipidemic type 2 diabetic patients, the MDA/LDL-cholesterol ratio was also negatively correlated with the LDL-cholesterol/apoB ratio (r = −0.75, P &lt;0.001) because of the highly significant negative correlation in type 2 diabetic women (r = −0.89, P &lt;0.01). Conclusions: LDL from well-controlled type 2 diabetic women is smaller and more prone to form peroxides. This could explain why diabetic women are at greater risk of cardiovascular disease.

Introduction: Patient counseling can be helpful in improving the outcome of disease management, particularly chronic diseases such as diabetes mellitus, which is common in Saudi Arabia. The present study looks to investigate the levels of counseling and satisfaction among patients attending diabetic clinics in outpatient hospital pharmacy in Al Ahsa, Saudi Arabia. Method: This is a cross-sectional investigation, carried out by using interview-structured questionnaire, targeting diabetes mellitus patients with or without comorbid states. The questionnaire was divided into 3 parts comprising of demographics, counseling types given while collecting prescription, and satisfaction rating of services provided. Result: More males than females participated; most of whom were college graduates older than 51 years. Sixty-three percent of the entire participants are type 1 diabetic patients, while 37% are type 2 diabetes mellitus patients. Coexistence of hypercholesterolemia was higher among type 1 diabetes patients with 51.9%, while hypertension was more common among type 2 diabetic patients representing 68.2%. Findings also showed that counseling was provided for medication use among type 1 diabetic patients but was deficient in the case of type 2 diabetic patients. Patients received low level of counseling on side effects and healthy lifestyle living. Satisfaction level was only 11.1%, indicating that counseling services might be deficient. Conclusion: This study has revealed poor counseling practices and low satisfaction levels in services provided by outpatient hospital pharmacies to diabetic patients. In the face of increasing prevalence of diabetes and comorbidity, counseling of diabetic patients is critical.

Related Mortality

Diabetes is one of the most chronic diseases in Western populations. Mortality rates in diabetic patients are higher than in the general population and their prognosis following any cardiovascular event is generally worse. Type 1 diabetic patients’ acute complications-related mortality decreases with time and the interval free from the diagnosis of diabetes until the development of chronic complications is larger although global mortality is still higher than that of sex- and age-matched healthy individuals. As a consequence of better primary and secondary preventions, recent data in the general population show that there is a trend towards decreased cardiovascular events and increased life expectancy. The same thing applies for type 2 diabetic patients. However, increased survival in the general population associated to epidemic bursts of obesity and sedentarily all over the globe, leads to a higher incidence of type 2 diabetes worldwide. This counteracts the diminution of diabetes-related mortality that would move forward on an ascending slope in the next decades.
