Objective. Diabetic kidney disease is one of the most common microvascular complications of diabetes mellitus. We aimed to analyze the association of thyroid parameters with kidney disorders, especially in euthyroid participants. Methods. The data were obtained from a cross-sectional study, the METAL study. Thyroid parameters, including thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (T3), thyroxin (T4), thyroid peroxidase antibody (TPOAb), and thyroglobulin antibody (TgAb), of 4136 participants with type 2 diabetes were measured. Two structure parameters of thyroid homeostasis, including the sum activity of step-up deiodinases (SPINA-GD) and thyroid secretory capacity (SPINA-GT), and two pituitary thyrotropic function indices, including Jostel’s TSH index (TSHI) and the thyrotroph thyroid hormone resistance index (TTSI), were also calculated. Kidney disorders were described according to the presence of reduced estimated glomerular filtration rate (eGFR) and/or higher urinary albumin to creatinine ratio (UACR). Results. The prevalence of kidney disorders increased with decreasing FT3 or T3 and increasing FT4 or T4 quartile levels (all P<0.05). After full adjustment, linear regression showed that UACR levels were negatively associated with FT3 and T3 (P<0.001). In addition, eGFR was positively associated with FT3 and T3 and was negatively associated with TSH and FT4 levels and TgAb positivity (all P<0.05). By using binary logistic regression, higher TSH and FT4 and lower FT3 and T3 were associated with kidney disorders (all P<0.05). Similar results were seen in sensitivity analyses, which were performed in 3035 euthyroid diabetic participants; however, TSH was no longer related to them. The area under the receiver operating characteristic curve (AUROC) of lower FT3 for existing kidney disorder was greater than that for any other thyroid hormones (all P<0.001). The cutoff value of FT3 for reduced eGFR was 4.39 pmol/L. Regarding thyroid homeostasis parameters, SPINA-GD was negatively associated with three statuses of kidney disorders, and TSHI and TTSI were positively associated with reduced eGFR (all P<0.05). Conclusions. Among patients with type 2 diabetes, elevated TSH and FT4 (or T4), lower FT3 (or T3), TgAb positivity, lower SPINA-GD, and higher TSHI and TTSI were associated with kidney disorders. The lower FT3, even within the normal range (<4.38 pmol/L), may be the factor most related to reduced eGFR compared with other thyroid hormones in diabetic patients.

Objective: To examine potential associations between neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, mean platelet volume (MPV), HbA1c and microvascular complications in diabetic patients from a cost-effectiveness perspective. Methods: One hundred patients with type 2 diabetes attending our outpatient unit between May 2018 and October 2018 were included, and 100 healthy individuals served as the control group. A retrospective file search was performed to collect information on hemoglobin, mean platelet volume (MPV), glycosylated haemoglobin (HbA1c), hematocrit (Hct), neutrophil and lymphocyte count, neutrophil/lymphocyte ratio (NLR), platelets (Plt), platelet/lymphocyte ratio (PLR), and microvascular complications (neuropathy, retinopathy, nephropathy). Results: Demographic and laboratory data were retrospectively controlled between diabetes (n=100) and healthy control (n=100) groups. The mean age in diabetic patients and healthy controls was 56.34 and 36.68 years, respectively. The mean NLR in diabetics and healthy controls was 2.48 and 2.11, the difference in NLR being significant (p=0.002). MPV in diabetics and controls was 8.54 and 8.53, respectively, and the difference was not significant (p=0.93). PLR was also similar, i.e. 149.7 and 145.3 in diabetics and healthy controls (p=0.067). With respect to microvascular complications, retinopathy was found to be significantly associated with MPV and NLR (p=0.015, and p=0.051), and nephropathy showed a significant association with NLR (p=0.027) among diabetics. In contrast with the two other microvascular complications, no significant association between neuropathy and NLR could be detected, while PLR and neuropathy was significantly associated (p=0.003). Conclusion: Microvascular complications may be associated with certain hematologic parameters, as suggested by comparisons both between diabetics and healthy individuals and within the group of diabetic individuals. We believe that hematologic parameters such as hematocrit, MPV, NLR, and PLR, which can be obtained through a simple complete blood count, may be utilized as cost-effective predictors of diabetic microvascular complications. Further prospective studies with larger sample size are required to better delineate these associations. doi: https://doi.org/10.12669/pjms.35.6.1150 How to cite this:Onalan E, Gozel N, Donder E.

BACKGROUND: Diabetic autonomic neuropathy is the reason for early morbidity and mortality on diabetic patients. The pathology not only cardiac innervation but microvascular is presented.AIMS: We estimated the parameters of skin microvascular blood flow in accordance with cardiovascular autonomic neuropathy (CAN) staging in diabetic patients. We also assessed other risk factors of CAN in patients with diabetes.MATERIALS AND METHODS: We included 76 patients with type 2 diabetes in the study (24 patients with resent-onset diabetes and/or diabetes without microvascular complications, 26 with diabetic sensorimotor neuropathy (SMN) and 26 with SMN and previous history of diabetic foot amputation). The SMN was diagnosed on the basis of patients complaints, anamnesis and data of clinical neurological examinations. CAN was detected using several cardiovascular autonomic reflex tests (CART) as a gold standard of diagnosis: the tilt-table test, a deepbreathing and Valsalva Maneuver, handgrip test, cold-stress vasoconstriction. According to the Toronto Diabetic Neuropathy Expert Group Recommendation all patients was separated on the groups: CAN 0 (all CARTs were normal), CAN 1 (possible/early CAN — one abnormal CART was presented), CAN 2 (definite/confirmed CAN –at least two abnormal CARTs were found), CAN 3 (severe/advanced CAN — in the cases of orthostatic hypotension in addition to CARTs abnormalities). Microvascular blood flow of skin at the nail roller of fingers skin was valuated at rest as well as in functional cold test by the method of High-frequency Ultrasonic Dopplerography using the “Minimax Doppler K” device (LLC JV “Minimax”, St. Petersburg, Russia).RESULTS: CAN 1 was found in 8% diabetic patients without microvascular complications, 42 and 21% patients with SMN and diabetic foot amputations respectively. CAN 2 was diagnosed in 27% patients with SMN and 58% patients history of diabetic foot amputations. CAN 3 in 8% and 19% cases in patients with SMN and history of diabetic foot amputations respectively. The parameters of microvascular blood flow at rest were significantly decreased in patients with confirmed/severe CAN in comparison with early staging of CAN and patients without CAN (Vm=2.5±0.66 sm/sec vs. 4.4±0.54 sm/sec and 5.1±1.01 sm/sec respectively; p=0.0033). The abnormal result of cold test was detected in 94% patients with confirmed/ severe CAN and 26% patients with CAN 1.CONCLUSIONS: This investigation has demonstrated in a cohort with type 2 diabetes patients with/without SMN and with/ without history of previously foot amputations that decrease the Vm (the variable of microvascular blood flow assessed by High-frequency Ultrasonic Dopplerography) lower than 2.4 sm/sec is associated with 6.4 times increased likelihood of confirmed/severe CAN as well as positive cold test result. That the patients with positive cold test results were 28.6 times more likely have confirmed/severe CAN.

Microvascular complications of Type 2 Diabetes Mellitus (T2DM), (retinopathy and nephropathy) have a similar etiopathogenetic mechanism besides genetic predisposition. Even though these two complications frequently co-exist, their frequency varies. The association of these two signicant complications and their coexistence needs a relook. To study prevalence of retinopathy and nephropathy in Type 2 diabetes mel Aim: litus. Comparison of diabetic retinopathy and nephropathy in Type 2 diabetes mellitus and its correlation of diabetic retinopathy and nephropathy with duration of illness and various risk factors that affects development, progression and severity of diabetic retinopathy and nephropathy. 100 diabetic patients were taken up for study for a period of one year meeti Methodology: ng the criteria for the present study. Detailed history was taken from patient and meticulous examination was done of all patients with special emphasis on renal and ophthalmic symptoms. Clinical data and investigation prole was tabulated. Statistical analysis was done. Among 100 patients, 22 had diabetic retinopathy. Among patients with diab Results & Conclusion: etic retinopathy, 68.18% patients had positive family history. Among 100 patients, 32 had diabetic nephropathy, mean FBS was 207 mg%, PPBS was 317.8 mg% and mean HbA was 9.2%. Among patients with diabetic retinopathy, mean FBS was 211 mg%, PPBS was 324.9 1c mg%, HbA was 9.5%. From this study it is found that diabetic nephropathy starts earlier than retinopathy. In this study 1c hypertension was found to accelerate progression into nephropathy and retinopathy.

Objective. Progranulin (PGRN) was recently introduced as a novel marker of chronic inflammatory response in obesity and type 2 diabetes capable of directly affecting the insulin signaling pathway. This study aimed to investigate the correlation between PGRN and type 2 diabetics with microvascular complications.Methods. PGRN serum levels and glucose metabolism related substance were measured in 84 type 2 diabetic patients with or without microangiopathies and 12 health persons. Further analyses of serum PGRN in different stages of diabetic microangiopathies were conducted.Results. Serum levels of PGRN were markedly higher in type 2 diabetic patients with microangiopathies. PGRN serum levels increased with the progress of diabetic microangiopathies with significantly highest values detectable in clinical diabetic nephropathy (CDN) and proliferative diabetic retinopathy (PDR) groups. Serum PGRN concentrations in all individuals positively and markedly correlated with systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), triglyceride (TG), urinary albumin excretion rate (UAER), blood urea nitrogen (BUN), creatinine (CRE), white blood cell (WBC), disease duration, IL-6, and TNF-α, while correlating negatively and significantly with eGFR. Multiple linear regression analysis showed that only UAER and CRE were independently associated with serum PGRN.Conclusion. PGRN might be considered as a marker for diabetic microangiopathy and its severity.

Abstract Background: Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic condition with various genetics and environmental influences that affects the capacity of the body to produce or use insulin resulting in hyperglycemia, which may lead to variable complications. It is one of the world’s rising health problems. There is emerging evidence that some genetic polymorphisms can impact the risk of evolving T2DM. We try to determine the relationship of (rs7903146) variant of the Transcription factor 7-like 2 (TCF7L2) gene with T2DM and its microvascular complications.Methods and Results: This case-control study included 180 subjects: 60 diabetic patients without complications, 60 diabetic patients with microvascular complications and 60 matched healthy controls. Genotypes of rs7903146 (C/T) SNP in the TCF7L2 gene were evaluated by real-time polymerase chain reaction via TaqMan allelic discrimination. Logistic regression was used to detect the most independent factor for development of diabetes and diabetic microvascular complications. Variant homozygous TT and heterozygous TC genotypes were significantly increased in diabetic without complications and diabetic with complications groups than controls (p=0.003, 0.001) respectively. The T allele was more represented in both patient groups than controls with no significant difference between patient groups. TT genotype as well as T allele was significantly associated with increased T2DM risk.Conclusion: The T allele of rs7903146 polymorphism of TCF7L2 confers susceptibility to development of T2DM. However, no significant association was found for diabetic complications.

Objective: To study the association between ankle brachial index (ABI) and microvascular complications in Type 2 diabetes (T2DM) patients with the coronary arterial disease (CAD). Methodology: A retrospective study was carried out on 3,458 T2DM patients reportedly with CAD, G1 (n=33), and without CAD, G2 (n=3125), who had given the ABI test. ABI was defined as normal (1.0 - 1.4) and abnormal (<1.0 and >1.4). The logistic regression analysis was used to identify the determinants of CAD positive outcomes in T2DM patients. Results: Overall, patient percentage-wise CAD 10% (333), abnormal ABI 26% (913), neuropathy 37% (1278), nephropathy, 8% (293), and retinopathy <1% (24). The ABI abnormality and CAD positives were higher in patients with nephropathy (32 and 20%) than in neuropathy (28 and 13%). Age-wise, 52 and 62% of neuropathy and nephropathy patients, respectively, were >60 years and had shown increased ABI abnormality from age 50 years onwards. The logistic model had shown nephropathy patients, [OR-1.8 [1.26-2.58], - p-0.001] in association with abnormal ABI, [OR-1.27 [95% CI, 0.99–1.63], p- 0.057] predicted to have CAD positive outcomes. While neuropathy, OR-0.69, [0.54 - 0.90], and hypertension, OR-0.43 [0.33 - 0.57] were not contributing towards CAD in our study population. Conclusion: Type 2 diabetes patients with abnormal ABI were predicted to have a 27% increased odds ratio of CAD outcome and 80% in the presence of nephropathy. Thus, as part of comprehensive diabetes care, albuminuria screening along with ABI measurement is being suggested.

A particular allele of the carnosinase gene (CNDP1) is associated with reduced plasma carnosinase activity and reduced risk for nephropathy in diabetic patients. On the one hand, animal and human data suggest that hyperglycemia increases plasma carnosinase activity. On the other hand, we recently reported lower carnosinase activity levels in elite athletes involved in high-intensity exercise compared with untrained controls. Therefore, this study investigates whether exercise training and the consequent reduction in hyperglycemia can suppress carnosinase activity and content in adults with type 2 diabetes. Plasma samples were taken from 243 males and females with type 2 diabetes (mean age = 54.3 yr, SD = 7.1) without major microvascular complications before and after a 6-mo exercise training program [4 groups: sedentary control ( n = 61), aerobic exercise ( n = 59), resistance exercise ( n = 63), and combined exercise training ( n = 60)]. Plasma carnosinase content and activity, hemoglobin (Hb) A1c, lipid profile, and blood pressure were measured. A 6-mo exercise training intervention, irrespective of training modality, did not decrease plasma carnosinase content or activity in type 2 diabetic patients. Plasma carnosinase content and activity showed a high interindividual but very low intraindividual variability over the 6-mo period. Age and sex, but not Hb A1c, were significantly related to the activity or content of this enzyme. It can be concluded that the beneficial effects of exercise training on the incidence of diabetic complications are probably not related to a lowering effect on plasma carnosinase content or activity.

AbstractData concerning the long-term effects of n-3 and n-6 PUFA on disease control and development of complications in diabetic patients are inconsistent. The relationship between plasma phospholipid PUFA and total mortality in type 2 diabetes is unknown. The present study aims to investigate the association between plasma phospholipid fatty acid relative concentrations expressed as weight percentage and total mortality in patients with type 2 diabetes. Mortality rates were evaluated at 5, 10, 15 and 20 years in patients with newly diagnosed diabetes (n 323) and matched non-diabetic controls (n 200) recruited from the Nord-Trøndelag Health (HUNT) Study, Norway. Kaplan–Meier survival curves were constructed and Cox regression analysis was used to calculate hazard ratios (HR) adjusted for biochemical and clinical covariates. After 10 years of follow-up, EPA in the diabetic population was negatively associated with total mortality, with an HR at the fifth quintile of 0·47 (95 % CI 0·25, 0·90) compared with the first quintile. In contrast, DHA was positively associated with total mortality, with an HR at the fifth quintile of 2·87 (95 % CI 1·45, 5·66). Neither EPA nor DHA was associated with total mortality in matched non-diabetic controls. In conclusion, plasma phospholipid relative concentrations of EPA were negatively associated, while those of DHA were positively associated with total mortality in diabetics. This difference in associations suggests a differential effect of EPA and DHA in patients with type 2 diabetes.

Background: Anemia is the most common blood disorder in patients with Type 2 diabetes. The hematological profile of diabetic patients is often missed clinically until to start the manifestation of clinical features of anemia. Anemia increases the hindrances and financial burden on the patient by frequent hospitalization. It increases the risk of microvascular complications, heart diseases, morbidity and death in diabetes mellitus. Therefore, it is imperative to recognize and treat anemia for the sake of patient care. Objectives: To evaluate the frequency of anemia in Type 2 Diabetic patients attending diabetic outpatients clinics of Mirpurkhas, Sindh. Methodology: A case-control study has been done to compare the hemoglobin level of Type 2 diabetics and non-diabetics. The data was collected over a period of three months from the patients who were visiting the diabetes clinic for their regular checkup. Data for controls were collected from the patient’s attendants. Diabetics and non-diabetics were under observations throughout the period. There were 206 subjects’ including 106 diabetics (52 females and 54 males) and 100 non-diabetics (50 females and 50 males). Research concerns included the duration of the disease, family history & presence of hypertension. Methods such as cyan methemoglobin were used to estimate hemoglobin & random blood glucose by glucose oxidase as recommended by the World Health Organization (WHO) and then read through Micro-lab 300 chemistry analyzer. Results: The frequency of occurrence of anemia in diabetics was 33.3% in males and 48.1% in females. Whereas in controls, 16.0% males and 32.0% females were anemic. The family history of diabetes and hypertension was also found higher among diabetic individuals as compare to healthy counterparts. Conclusion: The study has shown that anemia is twice as common in diabetics as compared with non-diabetics. Early diagnosis of anemia in a diabetic patient, and to treat so, will improve the quality of life and delay the complications to be developed in these patients.
