Periodontal disease (PD), a chronic inflammatory condition characterized by destruction of the supporting tissues of the teeth, increases the risk of complications in diabetics. Diabetic retinopathy (DR) is a microvascular complication of prolonged hyperglycaemia. There appears to be a similarity in the pathogenesis of DR and PD. Hence, this study aimed to investigate the association, if any, between DR and PD, correlate the severity of DR with the severity of PD, and investigate the association between glycated haemoglobin (HbA1c), serum creatinine and periodontal variables. The periodontal status of 200 adult diabetic patients in the age group of 30–65 years with varying severity of DR was assessed. Evaluation of the severity of PD was assessed by recording clinical parameters. Haematological investigations including glycated haemoglobin (HbA1c) and serum creatinine were estimated before the initiation of treatment for DR. A statistically significant association between the mean duration of diabetes mellitus (DM) and the severity of DR and PD was found. The severity of PD was directly correlated with the severity of DR. There was a significant association between the levels of HbA1c and serum creatinine and severity of DR and PD. There could be a plausible relationship between DR and PD. Further prospective studies on a larger population with longer follow-ups are required to ascertain whether PD and its severity directly affect the progression and severity of DR.

Objective: This cross-sectional study was designed to give insights into relationship between Insulin-Growth-Factor 1 (IGF-1) levels and diabetic retinopathy (DR) in a sample of  thalassaemia major(TM) patients with insulin dependent diabetes mellitus (IDDM). Τhis relation was not previously evaluated, despite the fact that both diseases co-exist  in the same patient. The  study   also  describes the clinical and biochemical profile of the associated complications in TM patients with and without IDDM.   Design: A population-based cross-sectional study.  Participants:The study  includes 19 consecutive TM patients with IDDM and 31 age- and sex-matched TM patients without  IDDM who visited our out-patient clinics for an endocrine assessment Methods: An extensive medical history, with data on associated complications and current medications, was obtained. Blood samples were drawn in the morning after an overnight fast to measure the serum concentrations of IGF-1, glucose, fructosamine , free thyroxine (FT4), thyrotropin (TSH) and biochemical analysis . Serologic screening assays for hepatitis C virus seropositivity (HCVab and HCV-RNA) were also evaluated,  applying routine laboratory methods.Plasma total IGF-1 was measured by a chemiluminescent immunometric assay (CLIA) method. Ophthalmology evaluation was done by the same researcher using stereoscopic fundus biomicroscopy through dilated pupils. DR was graded using the scale developed by the Global Diabetic Retinopathy Group. Iron stores were assessed by direct and indirect methods. Results:Eighteen TM patients with IDDM (94.7 %) and 10 non-diabetic patients (32.2 %) had IGF-1 levels below the 2.5th percentile of the normal values for the Italian population. The mean serum IGF-1 concentrations were significantly lower in the diabetic versus the non-diabetic TM groups (p < 0.001). DR was present in in 4 (21 %) of 19 TM patients with IDDM and was associated with the main classical risk factors, namely inefficient glycemic control  and duration of disease but not  hypertension. Using the scale developed by the Global Diabetic Retinopathy Group, the DR in our patients was classified as non proliferative diabetic retinopathy (NPDR). Only few numbers of microaneurysms [1-3] were detected. Our data also confirm the strong association of IDDM in TM patients with other endocrine and non-endocrine complications.Conclusions: These results , although on a small number of patients, suggest a possible ‘protective’ role of low IGF-1 in the development of DR in TM patients

Diabetic retinopathy (DR) is one of the main causes of visual loss in individuals aged 20–64 years old. The aim of this study was to investigate, in a multicenter retrospective cross-sectional study, sex-gender difference in DR in a large sample of type 2 diabetic patients (T2DM). 20,611 T2DM regularly attending the units for the last three years were classified as having: (a) No DR (NDR), (b) nonproliferative DR (NPDR), or (c) preproliferative/proliferative DR (PPDR). DR of all grades was present in 4294 T2DM (20.8%), with a significant higher prevalence in men as compared to women (22.0% vs. 19.3% p < 0.0001). Among DR patients, both NPDR and PPDR were significantly more prevalent in men vs. women (p = 0.001 and p = 0.0016, respectively). Women had similar age and BMI, but longer diabetes duration, worse glycemic metabolic control, and more prevalence of hypertension and chronic renal failure (CRF) of any grade vs. men. No significant differences between sexes were evident in term of drug therapy for diabetes and associate pathologies. Conclusions: In this large sample of T2DM, men show higher prevalence of DR vs. women, in spite of less represented risk factors, suggesting that male sex per se might be a risk factor for DR development.

Background: Diabetic retinopathy (DR) is one of the major visual morbidities associated with diabetes. This study determined the levels of serum high-sensitivity C-reactive protein (hs-CRP) in patients with DR and to correlate the estimated levels of serum hs-CRP with the severity of DR and other coexisting factors.Methods: This was a cross-sectional study conducted between March 2009 and August 2010 and included patients with type 2 diabetes mellitus (T2DM) with or without DR. A detailed fundus evaluation was performed using direct and indirect ophthalmoscopy. The retinopathies were observed and documented in accordance with the Kanski's system of classification as background DR (BDR), pre-proliferative DR (PPDR), and proliferative DR (PDR). Laboratory investigations determined the levels of fasting blood glucose (FBG), postprandial blood glucose (PPBG), glycosylated hemoglobin, urine albumin excretion, and serum hs-CRP levels.Results: In total, 80 patients with T2DM were included (DR group, n=40 [BDR, n=22; PDR, n=11; PPDR, n=7]; control group, n=40). Highest serum hs-CRP levels were found in PDR group (6.68 mg/L), followed by PPDR and BDR group (3.2 mg/L and 1.56 mg/L, respectively). The PDR group showed the longest duration of diabetes (16 years), highest FBG (221.8 mg/dL) and HbA1c (6.68 mg/L). The incidence of albuminuria and maculopathy was higher in PDR group (72.7% and 54.54%, respectively). A significant association of hs-CRP levels with DR in patients with T2DM was observed. A significantly (<0.005) positive correlation of hs-CRP was also observed with age, duration of disease, FBG, PPBG, and HbA1c.Conclusions: Patients with severe grades of retinopathy had significantly higher hs-CRP levels than patients with the milder grades.

Abstract Background: Hypomagnesemia has been shown to have a significant impact on both glycemic control and diabetes complications in type 2 Diabetes Mellitus (T2DM) patients. This study aims to assess the prevalence of hypomagnesemia in T2DM patients and find the association between serum magnesium levels and outcomes relevant to glycemic control and diabetic complications.Methods: A cross-sectional study was conducted and included 373 patients (222 males and 151 females). Serum magnesium levels were measured by the Colorimetric Endpoint Method using the Cobas C501system. Hypomagnesemia was determined to be a serum magnesium level <1.6 mg/dL. In addition, the following data were also obtained; patients' characteristics, anthropometric measurements, smoking status, HbA1c, co-morbidities, and therapeutic management. Results: Patients' mean age was 56.2 ±10.8 years, 24.6% were smokers, and most were overweight or obese. About 60% have a history of hypertension, and the majority have had diabetes for more than ten years. Their mean HbA1c level was 8.5±2. The prevalence of hypomagnesemia was 11% (95% CI: 8%-14.6%). It was found to be significantly higher among females (adjusted OR: 2.7, 95%CI: 1.2%-5.8%), patients with HbA1c ≥ 8% (adjusted OR: 2.4, 95%CI: 1.1%-5.5%), and patients with a history of diabetic retinopathy (adjusted OR: 2.7, 95%CI: 1.1%-7.1%). Conclusions: the study showed that hypomagnesemia is more prevalent in females and is associated with diabetic retinopathy and poor glycemic control. Having a sufficient magnesium level may be associated with better glycemic control and a reduced occurrence of complications.

Abstract Objectives To assess the prevalence and risk factors for fundus status among patients with type 2 diabetes mellitus (T2DM) using fundus screening in four towns of Quzhou city, Zhejiang province of China. Methods This cross-sectional study included 230 T2DM patients of four towns in Quzhou city, Zhejiang province of China. Participants were examined for the diabetes related fundus abnormalities and possible risk factors. Results Almost half of the T2DM patients (53.04%) reported with diabetic retinopathy (DR). Patients with diabetic retinopathy had longer duration of diabetes (P < 0.001) and higher HbA1c (P < 0.01). Risk factors for development of diabetic retinopathy included duration of diabetes and HbA1c. The prevalence of DR increased with the prolongation of the disease duration. The prevalence of DR was 28.79% in the group of disease duration < 5 years, 46.25% in the group of disease duration 5–10 years, 72.92% in the group of disease duration 10–15 years and 88.57% in the group of disease duration ≥ 15 years. What’s more, the prevalence of DR also increased with the increment of HbA1c levels. The prevalence of DR was 44.62% in the group of HbA1c < 7%, 53.13% in the group of HbA1c 7%-8%, 62.92% in the group of HbA1c ≥ 8%. Conclusion The prevalence of DR was disturbingly high. Risk factors for DR were similar to other studies and included duration of diabetes and HbA1c. Thus, good glycemic control remains the core foundation of managing DR.
