Introduction: Normal bacterial flora may be altered by a variety of factors. Objective: To study the aerobic bacterial conjunctival flora in patients with diabetes mellitus and to find its clinical significance by comparing the results to the conjunctival flora of non-diabetic subjects. Materials and methods: A total of 75 diabetic patients were included as cases and 25 nondiabetics as controls to compare the results. Specimens for the study of conjunctival flora were taken by rubbing sterile cotton-tipped swabs to the inferior palbebral conjunctiva. The conjunctival culture report of the patients with diabetic mellitus was compared to that of nondiabetic subjects. Results: Positive conjunctival cultures were seen in a higher percentage of patients with diabetes (unilateral and bilateral positive conjunctival cultures 34.66 % and 58.66 % respectively) compared to that in non-diabetic controls (unilateral and bilateral positive conjunctival cultures 24 % and 16 % respectively). Diabetics showed a higher proportion of coagulase negative staphylococci (45.33 %), compared to the non-diabetic group (16 %). Among the diabetic patients, positive conjunctival cultures were detected more frequently in those with diabetic retinopathy compared to those without retinopathy. A higher proportions of bilateral positive conjunctival cultures were seen in cases with proliferative diabetic retinopathy (38.63 %) in comparison to patients with no retinopathy and different stages of non-proliferative diabetic retinopathy. Conclusion: The conjunctival floral pattern with increased bacteria in diabetics is a predominant cause of many diabetes-related ocular infections. The presence of diabetic retinopathy is an indicator for increased colonization of conjunctiva, and its severity correlates with the severity of diabetic retinopathy.

Abstract Summary: Background: Erythropoietin (Epo) is one of systemic angiogenic factors, and its role in ocular angiogenesis and in diabetic retinopathy (DR) is not yet fully understood. Latest research data reveal possible correlation of higher EPO concentrations of erythropoietin in blood and in the eye, with more severe of stages of DR. The main aim of this work was to examine the possible influence of serum concentrations of erythropoietin on the development and stages of diabetic retinopathy in patients with diabetes mellitus type 2. Methods: The research involved 90 patients examined at University Eye Clinic in Clinical Center of Vojvodina in Novi Sad, Serbia. First group comprised of 60 patients with diabetes mellitus lasting 10 years or more, with diabetic retinopathy. Second, control group, consisted of 30 healthy individuals. In the first group of 60 diabetic patients, 30 of them had non-proliferative diabetic retinopathy (NPDR), and 30 had proliferative diabetic retinopathy (PDR). Laboratory EPO serum levels were determined, and they were correlated to the stage of DR. Concentration of EPO was assessed by ELISA method at the end of the study. Results: The highest average concentration of EPO in serum (9.95 mIU/ml) was determined in group of diabetics with PDR. The lowest average concentration of EPO in serum (6.90 mIU/ml) was found in control group. The average concentration of Epo in serum in group of diabetics with NPDR was 7.00 mIU/ml. EPO concentration in serum was elevated in group of PDR, and it was directly proportional to the level of clinical stadium of PDR, being significantly higher in moderate and severe subgroup of PDR comparing to control healthy subjects, NPDR and mild PDR (h=9.858, p=0.007). Conclusions: Significantly elevated serum concentration of EPO in advanced stages of DR, and positive correlation between EPO serum concentration and clinical stadium of PDR, suggest that erythropoietin presents one of the important growth factors from blood, which plays role in retinal ischemia and angiogenesis in diabetic retinopathy, especially in the proliferative stage of this disease. Keywords: diabetic retinopathy; erythropoietin; glycated hemoglobin; non-proliferative diabetic retinopathy; proliferative diabetic retinopathy.

Abstract Background: Routine eye examination plays a vital role in detecting diabetic retinopathy in its earliest stage before the onset of blindness. Patients’ knowledge about the nature and the consequences of diabetic retinopathy and routine eye checkup helps for timely identification and early treatment. However, there is limited evidence on knowledge of patients with diabetes mellitus on diabetic retinopathy and their eye check-up practices in Ethiopia. The aim of this study was to assess knowledge about diabetic retinopathy, eye check-up practice and associated factors of diabetic retinopathy among adult diabetic patients at Debark hospital, Northwest Ethiopia. Methods: Institution based cross-sectional study was conducted at Debark hospital, Northwest Ethiopia, from April 20/2018- May 20/2018. A pretested interviewer administered structured questionnaire was used to collect data among 230 diabetic patients aged 18 years and above. Data were entered in to Epi Info version 7 and exported to SPSS version 20 for analysis. Bivariable and multivariable binary logistic regression analyses were done. Odds ratio with 95% confidence level was determined and variables with p–value of < 0.05 were considered as statistically significant. Result: Out of 238 sample 230 were participated, among this, 119 (51.7%) were males. The mean age of the respondents was 49 (SD ±17.6) years. One hundred nine (47.4%) participants had good knowledge and 91 (39.6%) had good eye check-up practice. Urban residence [AOR= 2.65;95% CI: 1.16-6.07)]), monthly income of 3501-8000 birr [AOR=4.54;(1.31-15.7)], type II diabetes mellitus [AOR=3.9;(1.6-9.6)], duration of diabetes (6-12 years[AOR=4.4;(1.4-13.5)]), history of eye disease [AOR=5.5;(2.3-13.0)] were associated with good knowledge. Similarly, longer duration of diabetes (13-25 years [AOR=3.77; (1.05-13.5)]) and history of eye disease [AOR=2.47; (1.09-5.62)] were associated with good eye check-up practice. Conclusion: The proportion of good knowledge about diabetic retinopathy among diabetic patients at Debark hospital was fair (47.4%) and good eye check-up practice (eye examination at least once in the past year) was low (39.6%). Longer duration of diabetes and history of eye disease were identified as positive factors for good knowledge and eye check-up practice. Knowledge and regular eye check-up practice needs to be enhanced through provision of appropriate health education.

Aim: To study the relationship between severity of diabetic retinopathy (PDR or NPDR) and systemic complications of diabetes mellitus such as Neuropathy, Nephropathy or Cardiovascular manifestation as hypertension. Methods and Materials: This prospective observational study of 100 patients suffering from diabetic retinopathy. Such patients were recruited as a part of the study and further examined for any other systemic abnormality as neuropathy, nephropathy or hypertension. Statistical Analysis: Chi square test, univariate and multivariate logistic regression analysis was performed. P value < 0.05 was taken as significant. Results: Male: Female ratio of presence of diabetic retinopathy was 2.13: 1. The rate of proliferative diabetic retinopathy (PDR) was 1.47 % in persons who had diabetes for less than 5 years to 7.35 % in persons who had diabetes more than 15 years. In our study, it was seen that nephropathy was present in 35.71 % cases with PDR as compared to 8.93% of cases with Non proliferative diabetic retinopathy (NPDR). Conclusion: Our study showed that there is a significant correlation between severity of retinopathy and duration in type 2 Diabetes mellitus patients. Maximum number of patients with Diabetes mellitus having cardiovascular involvement, had hypertension (68%).In patients suffering from neuropathy as a complication of DM, maximum number of patients had diabetic foot (56%).It was seen that the severity of diabetic retinopathy had some association with presence of nephropathy. Also it can be postulated that patients with severe NPDR and PDR have high risk of developing nephropathy than patients suffering with mild and moderate NPDR. Hence it can be recommended that all patients of diabetes mellitus suffering from clinically significant neuropathy, nephropathy or hypertension as a complication of diabetes should always be screened for presence of retinopathy. Further studies with larger sample size are to be conducted to further look into this association. Keywords: Diabetic retinopathy, Diabetic nephropathy, diabetic neuropathy, complications

Objective Adropin, a newly identified regulatory protein encoded by Enho gene, is correlated with insulin sensitivity and diabetes. The aim of this study is to determine whether serum and vitreous adropin concentrations are correlated with the presence of diabetic retinopathy. Methods A population of 165 patients with type 2 diabetes mellitus (52 without diabetic retinopathy, 69 with non-proliferative diabetic retinopathy and 44 patients with proliferative diabetic retinopathy) was enrolled in this study. The control group enrolled 68 healthy subjects who had underwent vitrectomy for retinal detachment. Serum and vitreous adropin concentrations were examined using enzyme-linked immunosorbent assay method. Results Control subjects had significantly higher serum and vitreous adropin concentrations compared with diabetic patients. Serum and vitreous adropin concentrations in proliferative diabetic retinopathy patients were significantly reduced compared with those in non-proliferative diabetic retinopathy patients and type 2 diabetes mellitus patients without diabetic retinopathy. In addition, there were lower serum and vitreous adropin concentrations in non-proliferative diabetic retinopathy patients compared with type 2 diabetes mellitus patients without diabetic retinopathy. Logistic regression analysis revealed that serum and vitreous adropin were associated with a decreased risk of type 2 diabetes mellitus and diabetic retinopathy. Conclusion Serum and vitreous adropin concentrations are negatively associated with the presence of diabetic retinopathy.

Aim/hypothesis The aim of our study was to characterize the human salivary proteome and determine the changes in protein expression in 2 different stages of diabetic retinopathy with type-2 diabetes mellitus: (1) with non-proliferative diabetic retinopathy (NPDR) and (2) with proliferative diabetic retinopathy (PDR). Type-2 diabetes without diabetic retinopathy (XDR) was designated as control. Method In this study, 45 saliva samples were collected (15 samples from XDR control group, 15 samples from NPDR disease group and 15 samples from PDR disease group). Salivary proteins were extracted, reduced, alkylated, trypsin digested and labeled with iTRAQ before analyzing by Orbitrap fusion tribrid mass spectrometer. Proteins annotation, fold change calculation and statistical analysis were interrogated by Proteome Discoverer. Biological pathway analysis was performed by Ingenuity Pathway Analysis. Data are available via ProteomeXchange with identifiers PXD003723-PX003725. Results A total of 315 proteins were identified from the salivary proteome and 119 proteins were found to be differentially expressed. The differentially expressed proteins from the NPDR disease group and the PDR disease group were assigned to respective canonical pathways indicating increased LXR/RXR activation, FXR/RXR activation, acute phase response signaling, sucrose degradation V and regulation of actin-based motility by Rho in the PDR disease group compared to the NPDR disease group Conclusions/Interpretation Progression from non-proliferative to proliferative retinopathy in type-2 diabetic patients is a complex multi-mechanism and systemic process. Furthermore, saliva was shown to be a feasible alternative sample source for diabetic retinopathy biomarkers.

Objective: To find a relationship between serum level of vitamin D with diabetic retinopathy and hearing loss in patients with diabetes mellitus type2. Study design and setting: This cross-sectional study was carried out at Ophthalmology, ENT and family physician Outpatient clinic of Mohsin Consultant Clinic Federal B Area, Karachi from study was April 2019 to December 2019. Methodology: Total 181 eligible type 2 diabetes mellitus patients. Complete ophthalmological, ENT and physical evaluation was carried out. Retinopathy and hearing status were recorded and were compared to serum 25-OH Vitamin D levels to find any association. SPSS version 23.0 was used to analyze the data. Results: Mean age of participants were found to be 60.56±7.3 (SD). When diabetic retinopathy status and hearing status was compared, non-proliferative diabetic retinopathy patients with normal hearing were 24(42.1%), with mild hearing 32(56.1%) and only 1(1.8%) with moderate-severe hearing loss was observed with P-value of <0.0001. Retinopathy status was compared with vitamin D levels. Insufficiency was seen in 14(38.9%) non-proliferative diabetic retinopathy, 2(5.6%) proliferative diabetic retinopathy patients and deficiency level was found in 33(32.7%) non-proliferative diabetic retinopathy and 15(14.9%) proliferative diabetic retinopathy patients. Level of vitamin D was compared to DR and HL status. Significantly low level of vitamin D was found with increasing severity of DR and HL with P-value <0.0001. Conclusions: Low level of vitamin D was associated with the severity of diabetic retinopathy and hearing loss in patients suffering from diabetes mellitus type2
