Aggregation activity of blood formed elements in patients with type 1 and type 2 diabetes mellitus

Aims. To assess differences in blood formed elements aggregation activity in patients with type 1 (T1) and type 2 (T2) diabetes mellitus(DM). Materials and methods. We studied blood samples from 88 patients with T1 and T2 DM. Platelet aggregation activity was assessed bymeans of ?Biola? aggregometer; we also determined platelet-lymphocyte and leucocyte-erythrocyte adhesion intensity. Results. We show that spontaneous platelet aggregation is markedly increased in patients with T1DM but remains normal or slightlyelevated in case of T2DM. In blood from patients with T2DM platelet aggregation in response to ADP, epinephrine, ristomycineand contact with collagen was generally increased, whereas in T1DM we often observed its secondary reduction. Data on plateletlymphocyteadhesion in T1DM is controversial, but in T2DM this process seems to be significantly suppressed. Quantity of leucocyteerythrocyteaggregates was sharply increased in both T1DM and T2DM. Conclusion. We've determined significant difference in blood formed elements aggregation activity between patients with T1 and T2 DM.

Background. It is well known that intramammary arterial calcifications diagnosed by mammography as a part of generalized diabetic macroangiopathy may be an indirect sign of diabetes mellitus. Hence, the aim of this study was to determine the incidence of intramammary arterial calcifications, the patient?s age when the calcifications occur, as well as to observe the influence of diabetic polineuropathy, type, and the duration of diabetes on the onset of calcifications, in comparison with nondiabetic women. Methods. Mammographic findings of 113 diabetic female patients (21 with type 1 diabetes and 92 with type 2), as well as of 208 nondiabetic women (the control group) were analyzed in the prospective study. The data about the type of diabetes, its duration, and polineuropathy were obtained using the questionnaire. Statistical differences were determined by Mann-Whitney test. Results. Intramammary arterial calcifications were identified in 33.3% of the women with type 1 diabetes, in 40.2% with type 2, and in 8.2% of the women from the control group, respectively. The differences comparing the women with type 1, as well as type 2 diabetes and the controls were statistically significant (p=0.0001). Women with intramammary arterial calcifications and type 1 diabetes were younger comparing to the control group (median age 52 years, comparing to 67 years of age, p=0.001), while there was no statistically significant difference in age between the women with calcifications and type 2 diabetes (61 years of age) in relation to the control group (p=0.176). The incidence of polineuropathy in diabetic women was higher in the group with intramammary arterial calcifications (52.3%) in comparison to the group without calcifications (26.1%), (p=0.005). The association between intramammary arterial calcifications and the duration of diabetes was not found. Conclusion. The obtained results supported the theory that intramammary arterial calcifications, detected by mammography could serve as markers of co-existing diabetes mellitus and therefore should be specified in radiologic report in case of their early development.

Background The origin of autoimmune disease type 1 diabetes is still unknown. Aim This study assessed the activation of CD4+ and CD8+ T-lymphocytes by human insulin and human glutamate decarboxylase (GAD) in patients with type 1 or type 2 diabetes mellitus (DM) and healthy volunteers. Materials and methods The expression of CD69, a marker of T-lymphocyte activity, was determined in whole blood samples by flow cytometry after 12 h of incubation with or without insulin or GAD. The analysis included samples from 12 type 1 DM patients, 14 type 2 DM patients and 12 healthy volunteers. Results Significant increases in the number of activated CD4+ and CD8+ T-lymphocytes following pre-incubation of whole blood samples with human insulin or GAD were observed in samples from patients with type 1 DM, whereas no activation of these cells was detected in samples from either type 2 DM patients or healthy subjects. Discussion These results indicated that latent pre-activation of CD4+ and CD8+ T-lymphocytes in response to insulin or GAD epitopes occurred in type 1 DM patients. Conclusion These findings suggest that pre-immunization against insulin and/or GAD might be associated with the development of type 1 DM. Alternatively, these results might reflect a non-specific, bystander autoimmune response.

Introduction/Objective. Hand functions have an enormous impact on activities of daily living in patients with diabetes mellitus (DM), such as self-care, administering insulin injections, and preparing and eating meals. The aim of the study was to evaluate hand functions and grip strength in patients with type 1 and type 2 DM. Methods. This was an observational case-control study investigating the hand functions and grip strength in patients with type 1 and type 2 DM. The study comprised 41 patients with type 1 DM aged 25?50 years sex- and age-matched, 40 non-diabetic controls, and 91 patients with type 2 DM aged 40?65 years sex- and age-matched 60 non-diabetic controls. Patients with documented history of diabetic sensorimotor neuropathy and adhesive capsulitis were excluded. The Duruoz Hand Index was used to assess the functional hand disability. Grip strength was tested with a calibrated Jamar dynamometer. Results. The Duruoz Hand Index scores in patients with type 2 DM were significantly higher than in persons in the control group (p < 0.01), but there was no significant difference between the type 1 DM and the control group (p > 0.05). Grip strength values of patients with type 1 DM were significantly lower compared to those in the control group (p < 0.05), whereas there was no significant difference between patients with type 2 DM and their control group. There was a negatively significant correlation between grip strength and the Duruoz Hand Index scores in patients with both type 1 and type 2 DM (p < 0.05). Conclusion. Patients with type 1 DM and type 2 DM have different degrees of hand disability as compared to healthy control groups.

Diabetes mellitus patients often have hypercoagulable blood, as evidenced by the increased coagulation, impaired fibrinolysis,endothelial dysfunction and platelet hyperactivity. Hyperactive platelet is the major determinant of pro thrombotic state in DM. Byassessing the MPV and platelet aggregation, which is a marker of platelet activity, in patients with type 2 DM, it is expected to help theprediction of acute events. This research is aimed to know the differences of MPV and the aggregation of platelet between poor glycemiccontrol as well as good the control group in type 2 DM patients. This study was conducted in cross sectional method using 22 people withgood glycemic control and 28 people with poor one (glycemic control) from June to August 2013. Fasting blood samples were analyzedfor CBC, HbA1c, TG and platelet aggregation. MPV and platelet aggregation value were compared between groups using independentt-test. Based on this study, there is no significant difference in MPV and platelet aggregation between groups (p=0.598, p=0.464 (1 μM),p=0.868 (2 μM), p=0.984 (5 μM), p=0.401 (10 μM)). Mean Platelet Volume (MPV) correlate significantly with platelet aggregationat 1 μM and 5μM ADP concentration in good glycemic control group (r=0.591; p=0.004 at 1 μM ADP and r=0.521; p=0.013 at 5 μMADP). Mean platelet volume correlate significantly with the platelet aggregation at 2 μM ADP and the concentration in poor glycemiccontrol group (r=0.405; p=0.033). There are no significant differences in MPV and platelet aggregation between groups, but there is asignificant correlation between them (MPV and platelet aggregation) in the good glycemic control of the type 2 DM group.

Background: Diabetes mellitus (DM) is one of the most common metabolic disorders with millions of cases world-wide. Its effect on functioning of the central nervous system (CNS) and the peripheral nerves is a matter of current neurological research. Our study aimed to find out changes in auditory brainstem responses if any, in patients with type 1 and type 2 DM patients with apparently normal hearing.Methods: 50 cases each of type 1 and type 2 diabetic patients with normal hearing were chosen along with 50 healthy controls. Pure tone audiometry and brainstem evoked response audiometry (BERA) was performed in all cases. The BERA results were interpreted for the latencies of waves I, II, III, IV and V and inter-peak latencies I-III, I-V and III-V. Results: Significant delay in absolute latency of wave I, III, IV, V and inter-peak latencies I-V and III-V was seen in Type 1 diabetic patients. In Type 2 diabetic patients, latencies of waves I, II, III, IV and V and inter-peak latencies I-III, I-V and III-V were significantly delayed. There was no statistically significant difference in latency delay between type 1 and type 2 DM. No relation was found with the duration of DM.Conclusions: BERA is a non-invasive and easy to perform test that can detect minor CNS changes and can be used to detect peripheral (auditory nerve) and central neuropathy in diabetics even in absence of clinical signs and symptoms of deafness.

Aims: Since endothelial dysfunction precedes clinically significant diabetic vascular complications, circulating endothelial progenitor cells (EPCs) have generated interest as a biomarker of endothelial function and are considered a mirror for endogenous vasculo-regenerative capacity. So we aimed to assess EPCs count in adolescents with type 1 diabetes mellitus (T1DM) in comparison to those with type 2 diabetes mellitus (T2DM) and extend these findings to assess their relationship to other clinical and biochemical risks of endothelial dysfunction. Patients and Methods: Fifty Egyptian adolescents were included in this study, 20 with T1DM, 20 T2DM and 10 healthy control subjects. Patients are recruited from Diabetes and Endocrinology Unit, outpatient clinic of internal medicine department Tanta University Hospital, in the period from 2017 to 2019. EPCs count was determined by Flowcytometry, anthropometric measurements and laboratory investigations were done for fasting and 2-hours post-prandial blood glucose, serum lipid profile, HbA1c, urinary albumin creatinine ratio, fasting C peptide, and homoeostasis model assessment of insulin resistance (HOMA- IR). Results: In T1DM, EPCs count was significantly higher compared to T2DM(0.032) and control group(p0.001) and it was negatively correlated with age of patients and duration of diabetes but was positively correlated with HbA1c. While, the count was higher in T2DM compared to control with no statistically significant difference(p0.063) and negatively correlated with body mass index, waist circumference, blood pressure and HOMA-IR. Conclusion: Adolescents with T2DM have distressing clinical and biochemical findings and significantly lower count of (EPCs) than adolescents with T1DM. This puts them at potential higher risk for early development of endothelial dysfunction and less power of vascular repair that may potentiate early harboring of vascular complications.

Diabetes mellitus (DM) is a chronic and potentially life-threatening condition, incidence of which is increasing rapidly in the present era. Various studies showed conflicting relationship between DM and Hearing Loss (HL). The current study was carried out to find the effect of Type 1 and Type 2 DM on hearing. The study group consisted of 90 adults in the age range of 20 to 40 years from various hospitals in and around Calicut, Kerala. These participants were divided into three groups: Group1 (Experimental group 1), included 30 individuals with Type 1 DM; Group 2 (Experimental group 2), included 30 individuals with Type 2 DM and Group 3 (Control group) included 30 age-matched non-diabetic individuals with normal hearing sensitivity. Results of the study revealed that there was significant difference in the DPOAE amplitude between Type 1 and Type 2 DM with control group and there was no significant difference in the DPOAE amplitude between Type 1 and Type 2 DM group. From the results it can be concluded that DPOAE amplitude were reduced in both Type 1 and Type 2 DM when compared to control group. This could be attributed to damage of the cochlear Outer Hair Cells (OHCs). Further, it could be assumed that damage to the OHCs due to DM in both Type 1 and Type 2 groups are relatively equal.

Abstract: Diabetes melitus is a main medical problem around the world. WHO estimated that in 2000 there were 171 milion people with diabetes around the world and in 2030 there will be 366 million people. In diabetic patients, there are dysfunctions of platelet function caused microangiopati, macroangiopati, and platelet reactivity. Dysfunction of platelet function are associated with vascular complications of diabetes melitus. This study used an observational analytic method using comparative hypothesis test. This study was conducted to 30 diabetic patients, 15 patients have vascular complications while the other 15 have no vascular complications. Those patients are registered in Poliklinik Endokrin Metabolik RSUP Prof. Dr. R. D. Kandou Manado. The samples were processed in Prokita Laboratorium in Malalayang, Manado. Data analysis showed that there are significant difference between platelet aggregation value examined using ADP 5 µm agonist in diabetic patient with vascular complications and diabetic patients without vascular compications (p = 0.004). The same result were obtained from comparing the platelet agggregation value examined using ADP 10 µm agonist (p = 0.000). There are significant difference between platelet aggregation value in type 2 diabetes melitus patients with vascular complications and without complications. Keywords: Platelet aggregation, type 2 diabetes melitus, vascular complications. Abstrak: : Diabetes Melitus menjadi masalah kesehatan di dunia.
