The global coronavirus disease 2019 (COVID-19) pandemic was associated with multiple organ failure and comorbidities, such as type 2 diabetes mellitus (T2DM). Risk factors, such as age, gender, and obesity, were associated with COVID-19 infection. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is known to use several host receptors for viral entry, such as angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2 (TMPRSS2) in the lung and other organs. However, ACE2 could be shed from the surface to be soluble ACE2 (sACE2) in the circulation. The epigenetic factors affecting ACE2 expression include a type of small non-coding RNAs called microRNAs (miRNAs). In this study, we aimed at exploring the status of the sACE2 as well as serum levels of several upstream novel miRNAs as non-invasive biomarkers that might have a potential role in T2DM patients. Serum samples were collected from 50 T2DM patients and 50 healthy controls, and sACE2 levels were quantified using enzyme-linked immunosorbent assay (ELISA). Also, RNA was extracted, and TaqMan miRNA reverse transcription quantitative PCR (RT-qPCR) was performed to measure serum miRNA levels. Our results revealed that sACE2 is decreased in the T2DM patients and is affected by age, gender, and obesity level. Additionally, 4 miRNAs, which are revealed by in silico analysis to be potentially upstream of ACE2 were detectable in the serum. Among them, miR-421 level was found to be decreased in the serum of diabetic patients, regardless of the presence or absence of diabetic complications, as well as being differential in various body mass index (BMI) groups. The other 3 miRNAs (miR-3909, miR-212-5p, and miR-4677-3p) showed associations with multiple factors including age, gender, BMI, and serum markers, in addition to being correlated to each other. In conclusion, our study reveals a decline in the circulating serum levels of sACE2 in T2DM patients and identified 4 novel miRNAs that were associated with T2DM, which are influenced by different clinical and demographic factors.

Aims. To evaluate the levels of angiopoietin-1 (Ang-1), Ang-2, and vascular endothelial growth factor (VEGF) in serum and urine, and their association with albuminuria in patients with type 2 diabetes mellitus.Methods. In 113 type 2 diabetic patients with normoalbuminuria, microalbuminuria, and macroalbuminuria and 30 healthy controls, the levels of Ang-1, Ang-2, and VEGF in serum and urine were measured by enzyme-linked immunosorbent assay (ELISA).Results. Urinary and serum levels of Ang-2 were significantly higher in diabetic patients with normoalbuminuria than in healthy controls. Increased urinary Ang-2 level was positively associated with the degree of albuminuria. Urinary Ang-1 levels were significantly higher in normoalbuminuria patients and lower in macroalbuminuria patients than in controls. The levels of urinary VEGF increased in the albuminuria subgroup, though serum levels of Ang-1 and VEGF did not change. Urinary Ang-2 levels were correlated positively with albuminuria and negatively with glomerular filtration rate (GFR). Stepwise multiple regression analysis identified albuminuria (P<0.001) and GFR (P=0.001) as significant predictors of urinary Ang-2.Conclusions. Our data suggest that urinary Ang-2 is stepwise increased with renal damage in patients with type 2 diabetes mellitus and is associated with albuminuria.

Abstract Background Serum wnt1-induced signaling pathway protein 1 (WISP1) levels are increased with obesity, which is a common complication associated with lower extremity atherosclerotic disease (LEAD). However, to date, the relationship between elevated WISP1 levels and the incidence of lower extremity atherosclerotic disease (LEAD) in type 2 diabetes mellitus (T2DM) remains unclear. Methods 174 newly diagnosed type 2 diabetic patients were enrolled in our study. Patients were divided into two groups, LEAD group (n=100) and control group (n=74). Anthropometric parameters, blood pressure and some biochemical parameters were obtained. Body composition was detected by bioelectrical impedance analysis (BIA). Levels of serum insulin were determined by radioimmunoassay. Serum WISP1 and interleukin 6 (IL-6) levels were determined using an enzyme-linked immunosorbent assay. Results It was shown that serum WISP1 levels in diabetic patients with LEAD were higher than those without LEAD (P<0.001). Serum WISP1 levels were positively related with waist circumference (r=0.237, P=0.003), waist-hip ratio (r=0.22, P=0.006), visceral fat area (r=0.354, P<0.001), serum creatinine (r=0.192, P=0.012), interleukin 6 (r=0.182, P=0.032), c-reactive protein (r=0.681, P<0.001), triglycerides (r=0.119, P<0.001), fasting glucose (r=0.196, P=0.011), glycated hemoglobin (r=0.284, P<0.001), and HOMA-IR (r=0.285, P<0.026). Compared with the lowest tertile, the odds ratio of the middle tertile for LEAD incidence was 3.27 (95% CI, 1.24–8.64) and 4.46 (95% CI, 1.62–12.29) for the highest tertile after adjusting confounding factors. Conclusion The results suggest that increased serum WISP1 levels independently contribute to the incidence of LEAD in patients with newly diagnosed T2DM.

Abstract Objective Myonectin is one of the myokines and has gained interest as a potential new strategy to combat obesity and its associated disorders, such as type 2 diabetes mellitus (T2DM).The objective of this study was to investigate circulating serum myonectin levels in nondiabetes and T2DM and elucidate possible relationships between serum myonectin levels and metabolic parameters in patients with T2DM. Design A total of 362 Chinese patients with T2DM and 100 age- and sex-matched healthy controls were recruited in this study. Clinical characteristics, blood biochemistry, and circulating myonectin levels were measured by enzyme-linked immunosorbent assay. Results Circulating myonectin levels were significantly decreased in T2DM compared with controls. Obese nondiabetic controls had significantly lower serum myonectin levels compared with lean nondiabetic controls. In diabetic patients, serum myonectin concentrations were significantly negatively correlated with body mass index (BMI), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP), hemoglobin A1c (HbA1c), fasting insulin (Fins), the homeostatic model assessment of insulin resistance (HOMA-IR), visceral fat area, and subcutaneous fat area. After adjusting for covariates, multivariate stepwise regression analysis demonstrated that BMI, LDL-C, TG, HOMA-IR, and visceral fat were the main independent predictors of low serum myonectin concentrations. Conclusions Circulating myonectin levels were decreased in T2DM patients and in obese subjects. Moreover, serum myonectin levels were correlated with metabolic markers of T2DM. These data suggest that myonectin may be a useful marker in predicting the development of obesity and T2DM.

Depression is a comorbid condition in patients with Type 2 Diabetes mellitus (T2DM). S100B, a glia derived protein, is linked to depression and has been suggested as a biomarker for depression outcomes in several populations. However, to date there is no data about S100B levels and depression in patients with T2DM. Objective. We hypothesized that S100B serum levels are increased in patients with T2DM and recently diagnosed, drug-free depressive symptoms, and could be used for the diagnosis of depression in T2DM. Methods. Overall 52 patients (62 ± 12 years, female 66, 7%) with no history of depression deriving from the Diabetes out-patient clinic of our University Hospital underwent a one-to-one interview with a psychiatrist and filled a self-assessment (Zung) questionnaire. Serum S00B levels were compared between 30 (63±12 years, female 66, 7%) diabetic patients without depressive symptoms vs 22 patients (62 ±12 years, female 68, 2%) with T2DM and depressive symptoms. Results. There was no difference in serum levels of S100B between patients with T2DM without depressive symptoms vs diabetic patients suffering from depressive symptoms (2.1 (1.9-10.9) pg/ml vs 2.4 (1.9-14.8) pg/ml, p=0. 637+). Moreover, linear regression analysis did not show any association between lnS100B levels and depressive symptoms (β = 0.084, 95% CI 0.470-0.871, and p=0.552), Zung self-assessment score (β = 0.048, 95% CI -0.024-0.033, and p=0.738), and other patients’ characteristics. Conclusions. In patients with T2DM there is no correlation between S100B serum levels and newly detected mild depressive symptoms. The brain biochemistry pathways of depression in T2DM warrant further investigation in a larger scale population.

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.

Metallothionein (MT) as a potent antioxidant can affect energy metabolism. The present study was undertaken to investigate the association between MT gene polymorphism and type 2 diabetes mellitus. Using the PCR-based restriction fragment length polymorphism method, seven single nucleotide polymorphisms (SNPs) in MT genes (rs8052394 and rs11076161 in MT1A gene, rs8052334, rs964372 , and rs7191779 in MT1B gene, rs708274 in MT1E gene, and rs10636 in MT2A gene) were detected in 851 Chinese people of Han descent (397 diabetes and 454 controls). Several serum measurements were also examined randomly for 43 diabetic patients and 41 controls. The frequency distributions of the G allele in SNP rs8052394 of MT1A gene were significantly associated with the incidence of type 2 diabetes. There was no difference between patients and controls for the rest of six SNPs. Serum levels of interleukin-6 and tumor necrosis factor-α were higher, and serum superoxide dismutase activity was significantly lower in the diabetic group than those in the control group. For diabetic patients, serum superoxide dismutase activity was significantly lower in GG or GA carriers than those of AA carriers of rs8052394 SNP. Increased serum levels in diabetic patients were positively associated with rs964372 SNP, and type 2 diabetes with neuropathy was positively associated with rs10636 and rs11076161. These results suggest that multiple SNPs in MT genes are associated with diabetes and its clinical symptoms. Furthermore, MT1A gene in rs8052394 SNP is most likely the predisposition gene locus for diabetes or changes of serum superoxide dismutase activity.

Abstract Background:Hepatitis C virus (HCV) infection and type 2 diabetes mellitus (T2DM) are two major public health problems associated with increasing complications and mortality rates worldwide. The objective of this study to evaluate the prevalence of hepatitis C virus (HCV) infection in diabetic patients and to investigate the influence of several epidemiological and clinical factors on HCV infection. Method: A total number of one hundred and eighty diabetic patients were recruited for this study. Consented subjects made up of 71(39.4%) males and 109(60.56%) females were recruited for the study. While one-Hundred (100) Non-Diabetics (Controls) were recruited for this study. Structured questionnaires were administered to the consented participants to obtain relevant data. Sera samples were assayed for antibodies to HCV using an enzyme linked immunosorbent assay [Inteco Diagnostic Limited]. ELISA technique.Result: Overall prevalence of HCV infection among diabetes patients assayed was 13.3%. Out of which 8(11.3%) was obtained from the male subjects compared to 16 (14.7%) seropositivity recorded for the female subjects (P = 0.511; P > 0.05). Considering age distribution, Subjects aged 41-50 years recorded, 9 (22.5%) positivity (P= 0.238; P>0.05).Considering educational status of subjects screened, 22 (14.9%) positivity was rescored among subjects who have attained tertiary status of education.( P = 0.574;P>0.05).Risk factors considered showed that, 7 (18.9%) seropositive subject were alcoholic consumers(P value = 0.2621;P>0.05) while 5 (8.9%) recorded history of sharing sharp objects P= 0.2427;P>0.05).Conclusion: Our study shows a slightly higher prevalence of hepatitis C infection in type 2 diabetics. This call for urgent routine screening exercise among diabetic patients for HCV infection. This study also emphasizes the need for public enlightenment of the association between HCV infection and T2DM, to avert possible complications among diabetic patients.

Objective. Lipoprotein-associated phospholipase A2(Lp-PLA2) is extensively expressed by advanced atherosclerotic lesions and may play a role in plaque instability. We selected a group of elderly subjects that underwent transcatheter aortic valve implantation (TAVI) or balloon angioplasty (BA) and separated them into two groups, diabetic and nondiabetic, to compare the level of Lp-PLA2mass between them.Methods. 44 patients aged79.6±5.6years with symptomatic severe aortic valve stenosis underwent TAVI (n=35) or BA (n=9). 21 subjects had confirmed type 2 diabetes mellitus. Lp-PLA2mass was measured using an enzyme-linked immunosorbent assay kit (USCN Life Science, China) before and 3 days after the procedure.Results. Lp-PLA2mass was significantly elevated in this population (1296±358 ng/mL before TAVI;1413±268 ng/mL before BA) and further increased after TAVI (1604±437 ng/mL,P<0.01) or BA (1808±303 ng/mL,P<0.01). Lp-PLA2mass was significantly increased on the diabetic group before these interventions.Conclusion.Lp-PLA2may be a novel biomarker for the presence of rupture-prone atherosclerotic lesions in elderly patients. Levels of Lp-PLA2in diabetic patients may accompany the higher amount of small dense LDL particles seen in these subjects.

Clinical relevance To determine whether Vasohibin-1 which is a potential clinical biomarker is an independent risk factor in patients with diabetic retinopathy. Background Diabetic retinopathy (DR) is a common chronic microangiopathy in type 2 diabetes mellitus (T2DM). Vasohibin-1 (VASH-1) is an angiogenesis regulator that is closely related to pathological vascularization in DM. This study aimed to determine whether the serum levels of VASH-1 were related to the occurrence of DR in T2DM patients. Methods T2DM patients were divided into three groups: the nondiabetic retinopathy (NDR) group (n = 41), the nonproliferative diabetic retinopathy (NPRD) group (n = 40), and the proliferative diabetic retinopathy (PDR) group (n = 41). A control (CON) group consisting of 40 healthy subjects was also recruited. The serum levels of VASH-1 were measured by enzyme-linked immunosorbent assay kits. Results The concentration of VASH-1 in the CON groups was less significantly than that of the NDR, NPDR and PDR groups. ( P < 0.05). Body mass index, fasting plasma glucose (FPG), hemoglobina1c (HbA1C), blood urea nitrogen (BUN) and diabetic durations were positively correlated with the serum concentration of VASH-1 (all P < 0.05). In univariate logistic regression analyses, the HbA1C, diabetic durations, HDL-c, eGFR and VASH1 were associated with the presence of diabetic retinopathy. Multivariate logistic regression analysis showed that duration of diabetes were significantly associated with diabetic retinopathy. Conclusion We have shown that VASH-1 is associated with an increased risk of developing diabetic retinopathy. But the serum levels of VASH-1 are not independent risk factors for DR in T2DM.

Background: Adiponectin gene (ADIPOQ) variability may affect the risk for type 2 diabetes mellitus (T2DM) but it remains unclear whether it is involved in microvascular complications. </P><P> Objective: To explore the impact of ADIPOQ variability on markers of inflammation and angiogenesis in T2DM. </P><P> Methods: Overall, 220 consecutive T2DM patients from our outpatient diabetic clinic were genotyped for G276T (rs1501299) and T45G (rs2241766) single nucleotide polymorphisms of ADIPOQ gene. Serum levels of interleukin-6 (IL-6), intercellular adhesion molecule-1 (ICAM-1), vascular endothelial growth factor (VEGF) were measured by enzyme-linked immunosorbent assay and high sensitivity Creactive protein (hsCRP) by immunonephelometry. </P><P> Results: Homozygosity for the G allele on rs2241766 was associated with significantly lower serum VEGF and ICAM-1 levels compared with other genotype groups, but had no effect on IL-6. Genetic variability on rs1501299 was not associated with either VEGF or ICAM-1 levels, but T homozygotes for rs1501299 had significantly lower IL-6 concentrations compared with G carriers. Furthermore, the presence of the G allele on rs2241766 was associated with significantly lower HbA1c, whereas no associations were observed for both body mass index and hsCRP with either rs2241766 or rs1501299. </P><P> Conclusion: Genetic variability on adiponectin gene was associated with serum levels of inflammatory and angiogenetic markers. Further research is required to elucidate the role of adiponectin in the development and/or progression of microvascular disease in T2DM patients.
