RESUMO

Diabetic retinopathy (DR) and age-related macular degeneration (AMD) comprise a significant socio-medical problem for Russia. The article presents an analysis aimed at identifying the prerequisites for further research on the socio-economic consequences of retinal pathology. Studying the epidemiological aspects of DR and AMD, as well as the conditions for receiving medical aid helped define the main approaches to assessing the economic burden of retinal diseases in Russia. It also revealed the problems associated with completeness of registration and accounting of patients, the disparity between the volume of medical aid required and funding, and between the required and provided assistance for patients with these pathologies in clinical practice. Analysis of the disease cost will allow not only to determine the socio-economic consequences of retinal diseases, but also to find further directions for improving the quality of medical care for patients with DR and AMD in order to reduce its economic cost for the state and society. Evidently, there is a need for comprehensive assessment of the total burden of retinal diseases in Russia that would serve as a basis for subsequent assessment of the economic effectiveness of prevention and treatment measures.

RESUMO

Összefoglaló. Bevezetés: A diabeteses retinopathia minden harmadik cukorbeteget érinti a világban, és a dolgozó korú lakosság körében a vakság vezeto oka. Célkituzés: Tanulmányunk célja a diabeteses retinopathia prevalenciaalapú költségterhének meghatározása 2018-ban a 18 évnél idosebb korú lakosság körében Magyarországon. Módszer: Standardizált 'rapid assessment of avoidable blindness' (RAAB) + diabeteses retinopathia modul alapú metodikán alapuló modellel analizáltuk a diabeteses retinopathia költségterhét. A diabeteses retinopathia okozta gazdasági terhet a Nemzeti Egészségbiztosítási Alapkezelo és a páciensek oldaláról felmerülo költségeket analizálva vizsgáltuk. A prevalenciaalapú diabeteses retinopathia költségmodellt a skót diabeteses retinopathia klasszifikációnak és a diabeteses retinopathia súlyossági stádiumának megfeleloen állítottuk össze. Eredmények: A diabeteses retinopathia költségterhe 43,66 milliárd Ft volt 2018-ban. A két fo költségviselo az anti-VEGF-injekciók (28,91 milliárd Ft) és a vitrectomiák (8,09 milliárd Ft) voltak. Ez a két kezelési mód volt felelos a diabeteses retinopathiával kapcsolatban felmerülo összes költség 84,7%-áért. Az egy páciensre jutó átlagos költségteher 54 691 Ft volt hazánkban. Következtetés: A cukorbetegek szemészeti járó- és fekvobeteg-ellátása alulfinanszírozott hazánkban. A proliferatív diabeteses retinopathia és a diabeteses maculaoedema növekvo társadalmi-gazdasági terhe miatt érdemes volna javítani a megelozés, a szurés és a korai kezelés jelenlegi helyzetén. Orv Hetil. 2021; 162(8): 298-305. INTRODUCTION: Diabetic retinopathy affects every third people with diabetes mellitus in the world and is the leading cause of blindness in adults of working age. OBJECTIVE: The aim of this study was to analyse the economic burden associated with diabetic retinopathy in people aged 18 years and older in Hungary. METHOD: Rapid assessment of avoidable blindness (RAAB) with the diabetic retinopathy module (DRM) based diabetic retinopathy cost model study was conducted in Hungary in 2018. Economic burden of diabetic retinopathy was analysed from the perspective of the National Health Insurance Fund system and the patients. Our prevalence-based diabetic retinopathy cost model was performed according to the Scottish diabetic retinopathy grading scale and based on the diabetic retinopathy severity stadium. RESULTS: The total diabetic retinopathy-associated economic burden was 43.66 billion HUF in 2018. The two major cost drivers were anti-VEGF injections (28.91 billion HUF) and vitrectomies (8.09 billion HUF) in Hungary; they covered to 84.7% of the total cost among people with diabetes mellitus. The diabetic retinopathy-related cost per patient was 54 691 HUF in Hungary. CONCLUSION: Outpatient and inpatient eye care of people with diabetes mellitus are underfinanced in Hungary. Due to the increasing socio-economic burden of proliferative diabetic retinopathy and diabetic macular oedema, it would be important to invest in proliferative diabetic retinopathy and macular oedema prevention, screening and early treatment.

RESUMO

BACKGROUND: Diabetic retinopathy is a common complication of diabetes with a high incidence, and vitamin D deficiency is associated with diabetic retinopathy. Serum 25-hydroxy vitamin D [25-hydroxy-vitamind, 25 (OH) D], a product of vitamin D in the body, is considered the best indicator of a person's vitamin D nutritional status, and can be determined by measuring the concentration of 25 (OH) D. The purpose of this study is to systematically evaluate the correlation between serum 25-hydroxy vitamin D levels and diabetic retinopathy. METHODS: To search English databases (PubMed, Excerpta Medical Database (Embase), Web of Science, the Cochrane Library) and Chinese databases (Chinese National Knowledge Internet, Development, and Evaluation (CNKI), WanFang, Viper, Chinese Biomedical Literature Database) by computer about Clinical study on the correlation between serum 25-hydroxyvitamin D level and diabetic retinopathy from the establishment of the database to November 2020. Two researchers independently conducted data extraction and literature quality evaluation on the quality of the included studies, and meta-analysis is conducted on the included literatures using Stata12.0 and RevMan5.3 software. CONCLUSION: In this study, the correlation between serum 25-hydroxyvitamin D level and diabetic retinopathy was systematically evaluated to provide an evidence-based basis for clinicians. ETHICS AND DISSEMINATION: Private information from individuals will not be published. This systematic review also does not involve endangering participant rights. Ethical approval was not required. The results may be published in a peer-reviewed journal or disseminated at relevant conferences. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/CQY94.

RESUMO

OBJECTIVE: To assess whether vision-threatening retinopathy developed after 4 years in patients with type 2 diabetes with good glycemic control during follow-up. PATIENTS AND METHODS: Using data from the Action to Control Cardiovascular Risk in Diabetes and Action to Control Cardiovascular Risk in Diabetes Follow-on studies (conducted from January 1, 2001, to October 14, 2014), we investigated the incidence of vision-threatening retinopathy after 4 years in patients with type 2 diabetes with good or poor glycemic control. Patients with proliferative diabetic retinopathy at baseline were excluded. Vision-threatening retinopathy was defined as severe nonproliferative diabetic retinopathy, proliferative diabetic retinopathy, laser photocoagulation, or vitrectomy. Good and poor glycemic control was defined as mean glycated hemoglobin level less than 7% and 7% or greater during follow-up, respectively. RESULTS: This study included 2285 patients. Among patients with no retinopathy at baseline, the 4-year incidence of vision-threatening retinopathy was 0% (0 of 386) and 0.8% (6 of 721) in those with good and poor glycemic control, respectively (P=.54). Similarly, severe retinopathy was not observed at 8 years in patients who did not have retinopathy at 4 years. Among patients with mild to moderate nonproliferative diabetic retinopathy at baseline, the 4-year incidence of vision-threatening retinopathy was significantly higher in those with poor glycemic control than in those with good glycemic control (9.7% [77 of 790] vs 4.4% [13 of 297]; P=.004). Additionally, the remission rate of diabetic retinopathy was low in patients with a long duration of diabetes. Four-year incidences of vision-threatening retinopathy were higher in patients with retinopathy at baseline who had poorer glycemic control and longer durations of diabetes. CONCLUSION: It may be safe to extend screening intervals for diabetic retinopathy to 4 years or longer in patients with type 2 diabetes with no retinopathy.

RESUMO

Diabetic retinopathy (DR), caused by small vessel disease, is the main cause of blindness in persons with diabetes. Taiwan is one of the Asian countries with the highest prevalence rate of DR. The purpose was to investigate the related risk factors of DR in elderly patients with type 2 diabetes mellitus (T2DM), in Lee's Endocrinology Clinic. 792 T2DM patients over 60 years old were invited to have an outpatient visit at least every three months, and all of them were asked to undergo a standardized interview and collect their blood samples. Significant factors were being female (adjusted hazard ratio (HR): 1.287; 95% CI, 1.082-1.531), higher glycated hemoglobin (HbA1c) (HR: 1.067; 95% CI: 1.016-1.119), higher mean low density of lipoprotein cholesterol (LDL-c) (HR: 1.004; 95% CI: 1.001-1.006), and chewing betel nut (HR: 1.788; 95% CI: 1.362-2.347). This study showed that gender, the behavior of chewing betel nut, HbA1c, and LDL-c are important factors for the development of DR in elderly patients with T2DM. It is suggested that patients should control their HbA1c and LDL-c and quit chewing betel nut to prevent DR. This suggestion applies especially to female patients.

RESUMO

Background: Vascular endothelial growth factor (VEGF) gene polymorphisms have been shown to be associated with the risk of diabetic retinopathy (DR), but the results were inconsistent. The aim of this study was to systematically assess the associations between VEGF gene polymorphisms and different types of DR (nonproliferative DR and proliferative DR). Methods: Electronic databases PubMed, Embase, Web of Science, CNKI, and WANFANG DATA were searched for articles on the associations between VEGF gene polymorphisms and different types of DR up to November 6, 2019. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated, and subgroup analyses were conducted by ethnicity. Sensitivity analysis was conducted to assess the stability of the results. Publication bias was assessed by using the Egger regression asymmetry test and visualization of funnel plots. A systematic review was conducted for polymorphisms with a high degree of heterogeneity (I 2 > 75%) or studied in only one study. Results: A total of 13 and 18 studies analyzed the associations between VEGF SNPs and nonproliferative DR (NPDR) as well as proliferative DR (PDR), respectively. There were significant associations between rs2010963 and NPDR in Asian (dominant model: OR = 1.29, 95%CI = 1.04 - 1.60); and rs2010963 is associated with PDR in total population (dominant model: OR = 1.20, 95%CI = 1.03 - 1.41), either Asian (recessive model: OR = 1.57, 95%CI = 1.04 - 2.35) or Caucasian (recessive model: OR = 1.83, 95%CI = 1.28 - 2.63). Rs833061 is associated with PDR in Asian (recessive model: OR = 1.58, 95%CI = 1.11 - 2.26). Rs699947 is associated with NPDR in the total population (dominant model: OR = 2.04, 95%CI = 1.30 - 3.21) and associated with PDR in Asian (dominant model: OR = 1.72, 95%CI = 1.05 - 2.84). Conclusions: Rs2010963, rs833061, and rs699947 are associated with NPDR or PDR, which may be involved in the occurrence and development of DR.

RESUMO

One-third of Americans with diabetes will develop diabetic retinopathy (DR), the leading cause of blindness in working-age Americans. Social determinants of health (SDOHs) are conditions in a person's environment that may impact health. The objective of this study was to determine whether there is an association between SDOHs and DR in patients with type II diabetes. This cross-section study used data from the 2018 Behavioral Risk Factor Surveillance System (BRFSS). This study included people with self-reported diabetes in the US in 2018 (n = 60,703). Exposure variables included homeownership, marital status, income, health care coverage, completed level of education, and urban vs. rural environment. The outcome variable was DR. Logistic regression analysis were applied to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Alaskan Native/Native American (OR 2.11; 95% CI: 1.14-3.90), out of work (OR 2.82; 95% CI: 1.62-4.92), unable to work (OR 2.14; 95% CI: 1.57-2.91), did not graduate high school (OR 1.91; 95% CI: 1.30-2.79), only graduated high school (OR 1.43; 95% CI 1.08-1.97), or only attended college or technical school without graduating (OR 1.42; 95% CI: 1.09-1.86) were SDOHs associated with DR in patients with diabetes. Health care providers should identify these possible SDOHs affecting their diabetic patients.

RESUMO

Objective: To analyze and summarize the prevalence of diabetic retinopathy (DR) in China, and provide scientific evidence for its prevention and intervention. Methods: Literature search of PubMed, Web of Science, Embase, Wanfangdata, Vip and CNKI between 1990 and 2020 was performed to retrieve epidemiological studies of DR in China. The total prevalence of DR was analyzed by performing a meta-analysis, and the prevalences of DR in different regions and age groups were also evaluated by subgroup analyses. Results: A total of 40 studies were enrolled. The total sample size of the general population was 282 620, and the total number of diabetic patients was 47 022. The prevalence of DR in the general population and diabetic patients was 1.7% (95%CI: 1.4%-2.0%) and 22.4% (95% CI: 18.8%-26.1%), respectively. The highest prevalence of DR was found in patients aged 50-59 years (22.1%). Among the diabetic population, the prevalence of DR was high in North (27.7%) and Northeast China (23.7%), but the East China had the largest estimated number of DR patients (4 971 000). Moreover, the prevalence of DR in rural areas (34.0%) was higher than that in urban areas (18.7%). Conclusions: The prevalence of DR is high in Chinese diabetic population, and there are differences among regions and age subgroups. The results of the current meta-analysis emphasize the necessity of DR screening for diabetic population, especially in rural areas.

RESUMO

Diabetic retinopathy (DR) is the most frequent microvascular complication of diabetes mellitus (DM). DR remains a leading cause of blindness, currently accounting for 4.8% of the world's 37 million blindness cases. DR is one of the critical preventable causes of blindness. In Bangladesh, the number of studies reporting the prevalence and risk factors of DR in type 2 DM (T2DM) is limited. We conducted this cross-sectional study in a tertiary hospital in Bangladesh from March 2017 to August 2019 among 200 patients with T2DM for the presence and severity of DR by using color fundus photography in a dilated pupil. The diagnosis and grading of DR were made using the Early Treatment of Diabetic Retinopathy Study (ETDRS) Chart. Out of 200 subjects with T2DM, 35.5% had DR; the frequencies of NPDR and PDR were 19.0% and 16.5%, respectively. The mean age, diabetes duration, FPG, HbA1c, TG, TC, LDL-C, and serum creatinine were statistically higher, and eGFR was lower in the study subjects with DR than those without DR; BMI and HDL-C were indifferent in the two groups. The frequencies of males, subjects having monthly income of 10,000 Bangladeshi Taka (BDT) or more, smokers, hypertensives, and subjects having uncontrolled diabetes (HbA1c ≥7%), were higher in the DR group than the no DR group. Higher age (≥50 years), higher monthly income (≥10,000 BDT), urban residence, smoking, uncontrolled diabetes, and high LDL-C (≥100mg/dL) were found to be independent risk factors of DR in the study subjects. A large-scale nationwide study is needed to find out the actual prevalence of DR in Bangladesh.

RESUMO

BACKGROUND: Diabetic retinopathy (DR) is one of the serious complications of diabetes mellitus. Without further treatment, it can evolve into the stage of proliferation, which will lead to the formation of new blood vessels, vitreous hemorrhage, or anterior retinal hemorrhage, which will lead to severe vision loss and increase the risk of blindness. METHODS: The research literature on the risk factors of diabetic retinopathy published as of July 1, 2020 was searched through MEDLINE, Embase, ovid, Web of Science, Wanfang, CNKI, and other databases, The search strategy has been first developed in MEDLINE using MeSH subject headings combined with free-text terms and Stata12.0 software was used for meta-analysis. RESULTS: This study is ongoing and the results will be submitted to a peer-reviewed journal for publication. ETHICS AND DISSEMINATION: Ethical approval is not applicable, since this is an overview based on published articles. PROTOCOL REGISTRATION NUMBER: The registration number is INPLASY202070107, the DOI number is 10.37766/inplasy2020.7.0107.

RESUMO

Recently, telemedicine has become remarkably important, due to increased deployment and development of digital technologies. National and international guidelines should consider its inclusion in their updates. During the COVID-19 pandemic, mandatory social distancing and the lack of effective treatments has made telemedicine the safest interactive system between patients, both infected and uninfected, and clinicians. A few potential evidence-based scenarios for the application of telemedicine have been hypothesized. In particular, its use in diabetes and complication monitoring has been remarkably increasing, due to the high risk of poor prognosis. New evidence and technological improvements in telemedicine application in diabetic retinopathy (DR) have demonstrated efficacy and usefulness in screening. Moreover, despite an initial increase for devices and training costs, teleophthalmology demonstrated a good cost-to-efficacy ratio; however, no national screening program has yet focused on DR prevention and diagnosis. Lack of data during the COVID-19 pandemic strongly limits the possibility of tracing the real management of the disease, which is only conceivable from past evidence in normal conditions. The pandemic further stressed the importance of remote monitoring. However, the deployment of device and digital application used to increase screening of individuals and monitor progression of retinal disease needs to be easily accessible to general practitioners.

RESUMO

Objective: To evaluate the association between diabetic retinopathy (DR) and mean ocular perfusion pressure (MOPP) in patients with type 2 diabetes mellitus (T2DM). Methods: Patients from the Fushun Diabetic Retinopathy Cohort Study (FS-DIRECT), a community-based prospective cohort study conducted in northeast China, were included in this study. The presence and severity of DR were determined by grading fundus photographs according to the Early Treatment Diabetic Retinopathy Study (ETDRS) retinopathy scale. Systolic and diastolic blood pressure (SBP and DBP) were recorded using an electronic sphygmomanometer. Intraocular pressure (IOP) was measured using an iCare rebound tonometer. MOPP was calculated using the formula MOPP = 2/3 [DBP + 1/3 (SBP - DBP)] - IOP. Results: In total, 1,857 patients who had gradable fundus photography and MOPP data were enrolled in this study. Male patients had a higher MOPP than female patients (52.25 ± 8.75 vs. 50.96 ± 8.74 mmHg, P = 0.002). Overall, both male and female patients with any type of DR, non-proliferative DR (NPDR), or non-sight-threatening DR (non-STDR) had significantly higher MOPP relative to patients without DR. Increased MOPP (per 1 mmHg) was in turn associated with the presence of any type of DR [odds ratio ( OR) = 1.03, 95% confidence interval ( CI) : 1.02-1.04], NPDR ( OR= 1.03 95% CI: 1.02-1.04), and non-STDR ( OR= 1.03, 95% CI: 1.01-1.04) after adjusting for confounders. Increased MOPP (per 1 mmHg) was also associated with an increased likelihood of macular edema ( OR= 1.02 , 95% CI: 1.01-1.04). Conclusions: The results suggest that increased MOPP was associated with DR and macular edema in northeastern Chinese patients with T2DM.

RESUMO

PURPOSE: To investigate the knowledge and practices regarding diabetic retinopathy (DR) among diabetic patients included in a community-based primary health system (CBPHS) in China. METHODS: Diabetic patients aged 18 years and above registered in the CBPHS in Yueqing city, Zhejiang province were recruited. Information obtained by questionnaire included: demographic and socioeconomic status, knowledge about DR, and ocular and medical history. The primary outcome was whether the participant knew that DM can affect the eyes, defined according to the question: "Do you know diabetes mellitus (DM) can affect eyes? (yes or no)". A knowledge score was calculated based on the responses to seven questions, with 1 point awarded for a correct response and 0 points for an incorrect or uncertain answer. RESULTS: A total of 1972 diabetic patients were included in the study with an average age of 65.2±10.8 years, 45.7% were male. One thousand two hundred and nineteen patients (61.8%) knew that DM can affect the eyes. Significant differences in age, education, income status, insurance covering eye care, fasting blood glucose, duration of DM, history of hypertension existed between subjects who knew and those who did not know that DM can affect the eyes (P<0.05 for all). The proportion of correct answers to the DR knowledge questions ranged from 33.3% to 61.8%, with an average score of 3.65±2.47. In the multiple regression analysis, the knowledge score was significantly associated with age, education, income, history of hypertension, duration of DM, being told that regular examinations should be performed and concern about vision loss (P <0.01 for all). CONCLUSIONS: The knowledge toward DR among DM patients were still low within the chronic disease management system in eastern China. Routine ophthalmic screening, health care promotions, and educational programs should be emphasized and implemented for better DR prevention and management.

RESUMO

PURPOSE: To study the effect of type 2 diabetes on pupil diameter. PATIENTS AND METHODS: We carried out a case-control study at the Douala Obstetrics, Gynecology and Pediatric Hospital over a 5-month period. The cases were type 2 diabetic patients, and the controls were non-diabetic patients paired for age and gender. We studied the correlation between the duration of diabetes, fasting blood sugar and the horizontal pupil diameter. RESULTS: We included 35 patients in each group. The mean age was 56.6±10.01 years. Both groups included 17 males and 18 females. The mean duration of diabetes was 2.72±4.31 years, and the mean fasting blood sugar was 2.02±0.69g/L. The mean pupil diameter was similar in the two groups. On the right side, it was 4.75±0.73mm for controls and 4.52±0.69mm for cases (P=0.179). On the left side, it was 4.70±0.68mm and 4.42±0.73mm respectively for each group (P=0.101). The duration of diabetes was correlated to pupil diameter in the right eye (r=-0.43; P=0.01) and left eye (r=-0.45; P<0.01). No additional risk was found to be associated with diabetes for right pupil diameters (OR=0.79; P=0.33), or for left ones (OR=0.76; P=0.24). CONCLUSION: Pupil diameter is similar in diabetic and non-diabetic patients. However, the duration of diabetes appears to affect pupil diameter.

RESUMO

PURPOSE: To investigate the association between daily sunlight exposure duration and diabetic retinopathy in Korean adults with diabetes. METHODS: This study used data from the 2008-2011 Korea National Health and Nutrition Examination Survey. Overall, 1,089 patients with diabetes aged >40 years were included. The duration of daily sunlight exposure was assessed via health interviews. Comprehensive ophthalmic evaluations, including standard retinal fundus photography after pupil dilation, were conducted. Diabetic retinopathy was graded using the modified Airlie House Classification. Multivariate logistic regression analysis was performed to analyze the association between daily sunlight exposure duration and the diagnosis of diabetic retinopathy and non-proliferative diabetic retinopathy. RESULTS: The risk of diabetic retinopathy was 2.66 times higher in the group with ≥5 h of daily sunlight exposure than in the group with less exposure after adjusting for risk factors such as duration of diabetes, serum hemoglobin A1c level, hypertension, and dyslipidemia (P = 0.023). Furthermore, the risk of non-proliferative diabetic retinopathy was 3.13 times higher in the group with ≥5 h of daily sunlight exposure than in the group with less exposure (P = 0.009). In patients with diabetes for <10 years, the risks of diabetic retinopathy and non-proliferative diabetic retinopathy were 4.26 and 4.82 times higher in the group with ≥5 h of daily sunlight exposure than the group with less exposure, respectively (P < 0.05). CONCLUSIONS: This study revealed that sunlight exposure for ≥5 h a day was significantly associated with an increased risk of diabetic retinopathy and non-proliferative diabetic retinopathy in Korean patients with diabetes. The risks were significantly higher in patients with diabetes for <10 years. Therefore, reducing daily sunlight exposure could be an early preventive strategy against diabetic retinopathy in people with diabetes.

RESUMO

BACKGROUND: The effect of interarm blood pressure difference on the development of diabetic retinopathy, proteinuria and chronic kidney disease remains unknown. We investigated to determine the impact of interarm blood pressure difference on the prevalence of diabetic retinopathy, proteinuria and chronic kidney disease in patients with type 2 diabetes. METHODS: The study included 563 patients with diabetes, who were evaluated with a simultaneous bilateral blood pressure measurement. The cutoff values for interarm blood pressure difference were 5, 10 and 15 mmHg. Logistic regression analysis was used to explore the relation between interarm blood pressure difference and diabetic retinopathy, proteinuria and chronic kidney disease. RESULTS: Diabetic patients with systolic interarm blood pressure difference ⩾5, ⩾10 and ⩾15 mmHg showed an increased risk of diabetic retinopathy [adjusted odds ratio = 1.48 (95% confidence interval = 1.01-2.18), odds ratio = 1.80 (95% confidence interval = 0.99-3.22), odds ratio = 2.29 (95% confidence interval = 1.00-5.23)] after adjustment. There were significant associations between interarm blood pressure difference ⩾5 and ⩾10 mmHg and proteinuria [odds ratio = 1.68 (95% confidence interval = 1.15-2.44), 1.89 (95% confidence interval = 1.05-3.37)]. CONCLUSION: The association between interarm blood pressure difference and the presence of diabetic retinopathy emerged even for systolic interarm blood pressure difference ⩾5 mmHg without interaction of systolic blood pressure. Systolic interarm blood pressure difference should be considered a surrogate marker for vascular complication in patients with type 2 diabetes.

RESUMO

INTRODUCTION: The prevalence of diabetes mellitus is significantly increasing worldwide. Distal sensorimotor neuropathy (DSPN) is the most common and the earliest detectable microvascular complication. Due to its diverse clinical appearance and atypical symptoms, DSPN is often recognized in an advanced stage. AIM AND METHOD: In our study, the data of 431 patients who were examined using the Neurometer® between 2011 and 2018 at the Diabetic Neuropathy Center of the University of Debrecen were processed and the correlations between cardiovascular and microvascular complications, laboratory parameters and the severity of DSPN were investigated. RESULTS: The average age of patients was 63.4 years, 62% of them were women, and 92% had type 2 diabetes mellitus. The average duration of diabetes was 13.7 years. Cardiovascular disease (CVD) was diagnosed in 42% of the patients. The incidence of retinopathy was 12%, persistent microalbuminuria was 16%. Despite DSNP complaints, neuronal damage could not be detected in 19%; in the examined patients 49% had mild, 19% moderate and 13% severe neuropathy. Diabetes-related neurological damage was more serious in the presence of both diabetic retinopathy (p<0.001) and microalbuminuria (p<0.001). The incidence of these microvascular complications and the severity of DSPN showed a significant positive correlation (p<0.001). There was no correlation between the severity of peripheral neuropathy and the development of CVD, and we did not find any correlations between the severity of DSPN and CVD. CONCLUSION: Based on our investigation, correlation between the progression of diabetic neuropathy and cardiovascular complications was not found, although the progression of diabetic neuropathy indicated the development of other microvascular diseases. Peripheral neurological examination using the Neurometer® is appropriate for controlling the DSPN status and the establishment of the severity of neuropathy determines the quality of life in diabetic patients. Among these patients, the risk of CVD can be assessed by Ewing's test for autonomic nervous system function. Orv Hetil. 2020; 161(30): 1243-1251.

RESUMO

BACKGROUND: To assess the associations of various HbA1c measures, including a single baseline HbA1c value, overall mean, yearly updated means, standard deviation (HbA1c-SD), coefficient of variation (HbA1c-CV), and HbA1c variability score (HVS), with microvascular disease (MVD) risk in patients with type 2 diabetes. METHODS: Linked data between National Cheng Kung University Hospital and Taiwan's National Health Insurance Research Database were utilized to identify the study cohort. The primary outcome was the composite MVD events (retinopathy, nephropathy, or neuropathy) occurring during the study follow-up. Cox model analyses were performed to assess the associations between HbA1c measures and MVD risk, with adjustment for patients' baseline HbA1c, demographics, comorbidities/complications, and treatments. RESULTS: In the models without adjustment for baseline HbA1c, all HbA1c variability and mean measures were significantly associated with MVD risk, except HVS. With adjustment for baseline HbA1c, HbA1c-CV had the strongest association with MVD risk. For every unit of increase in HbA1c-CV, the MVD risk significantly increased by 3.42- and 2.81-fold based on the models without and with adjustment for baseline HbA1c, respectively. The associations of HbA1c variability and mean measures with MVD risk in patients with baseline HbA1c < 7.5% (58 mmol/mol) were stronger compared with those in patients with baseline HbA1c ≥ 7.5% (58 mmol/mol). CONCLUSIONS: HbA1c variability, especially HbA1c-CV, can supplement conventional baseline HbA1c measure for explaining MVD risk. HbA1c variability may play a greater role in MVD outcomes among patients with relatively optimal baseline glycemic control compared to those with relatively poor baseline glycemic control.
