Assessment of lipid profile with HbA1c in type 2 diabetic Iraqi patients

Abstract

Insulin-induced hyperglycemia is the hallmark of diabetes mellitus (DM), including various metabolic disorders. Diabetic people are more likely to develop dyslipidemia, hypertension, and obesity. Type 2 diabetes ‎(T2DM), the most common illness, is generally asymptomatic in its early stages and can go misdiagnosed for years. Diabetes screening may be beneficial in some cases since early identification and treatment can lessen the burden of diabetes and its consequences.‎ This study aimed to find the relationship between Glycated hemoglobin (HbA1c) ‎and lipid profile components in T2DM‎ patients. This descriptive-analytical and cross-sectional study was performed on the control group and T2DM patients in ‎Medical City in Baghdad between March and June 2021‎. A total of 90 patients with T2DM and ‎‎45 healthy control were included in this study. In the control group, healthy volunteer individuals participated. For all subjects, HbA1c, fasting blood sugar/FBS, and lipid profile (Total Cholesterol/TC, Triglyceride/TG, High-density Lipoprotein/HDL, Low-density Lipoprotein/LDL, and Very Low-density Lipoprotein/VLDL) were assessed. Among T2DM patients 62.22% (n= 56) were male and 37.78% (n= ‎‎34) were female. Mean ± SD levels of HbA1c, TC, TG, LDL, VLDL, HDL, and FBS were 7.33±0.56 ‎‎% (168.21±9.23, 146.10±9.64, 137.23±8.32, 41.05±5.86, 43.85±6.17, and ‎‎208.81±52.1) mg/dl respectively in the T2DM group. In the control group, ‎the Mean ± SD results of the same parameters were 4.91±0.27%, ‎‎(171.20±3.57, 116.60±8.25, 105.05±2.11, 41.83±4.92, 44.04±5.54, ‎‎96.20±7.8) mg/dl respectively. Results demonstrated statistically significant ‎‎differences between T2DM patients and control groups in HbA1c ‎‎(p equal to 0.0025), TG ‎(p equal to 0.015), LDL ‎ ‎(p=0.0029),‎ and FBS ‎(p=0.02‎). Pearson correlation analysis of HbA1c with other variables showed a significant ‎positive correlation with serum TC, TG, LDL, and ‎FBS ‎(r=0.573, P<0.01; ‎r=0.655, P <0.001; r=0.498, P<0.05‎; r=0.691, ‎P<‎0.001‎; ‎‏respectively). While the data showed a negative connection between HbA1c and HDL (r= - 0.562, P<0.01) The findings of this study reveal that diabetic people do not have a satisfactory HbA1c level. Furthermore, HbA1c shows a significant correlation with TC, TG, LDL, and VLDL, whereas it has a significant negative correlation with HDL. The study showed that HbA1c might be useful for predicting dyslipidemia in T2DM patients. Keywords: T2DM, Lipid profile, HbA1c.

Tumor necrosis factor (TNF)-α-308 gene polymorphism in children of Haemophilia A

“…Regarding sex, the majority of both groups were males. Our results are supported by the study of Nesheli et al 6,7 as they reported that the mean age of cases with inhibitors was 10.22 years. Their results revealed that the production of inhibitors in young populations was more significant than in older ones.…”

“…Also, A allele distribution was increased in positive inhibitors at 11.1%, then in negative inhibitors at 2.8%. Table (6) Following logistic regression analysis and adjusting for confounding factors, the only independent predictor of positive inhibitors was the number of factors 8 exposure days > 20 days (OR = 3.8) with a 95% CI (1.05-13.7).Table (7).…”

Immunological profile of diabetic foot ulcers: update review

“…The lifetime risk of getting a diabetic foot ulcer has been estimated to be as high as25%, and the reported annual incidence of diabetic foot ulceration ranges from 2.1% to 7.4% (10). It has been estimated that up to 15% of persons with T2DM have DFUs [11]. Globally, the incidence is estimated to be 6.3% (95%) with a reported 13.0% prevalence in North America.…”
