Serum chromium, glycosylated hemoglobin level and body mass index among control and uncontrol sudanese patients with type II diabetes mellitus: Correlation study

Background: Chromium is an essential micronutrient which is required for the normal functioning of insulin and regulation of blood sugar levels. It acts as a vital antioxidant for maintaining insulin homeostasis. In diabetes mellitus, the free radical production is increased and levels of antioxidants like chromium, vanadium, selenium and manganese are reduced. Aim: To study the level of serum chromium level in patients with type 2 diabetes mellitus and its association with glycemic control. Materials and Methods: One hundred and twenty individuals were enrolled in this study, classified into 60 type II diabetes mellitus (type II DM) patients and 60 apparently health as control group. Serum chromium and Glycosylated Hemoglobin (HbA1c) level were measured using atomic absorption spectrometry and Ichroma. Results: The results showed significant decrease in serum chromium level in type II DM patients (0.0151±0.005) when compared with healthy group (0.122±0.691) with p-value (0.002). In addition to that there was significant decrease in mean concentration of serum chromium level in controlled diabetic patients (0.0206± 0.003) when compared with uncontrolled diabetic patients (0.0120±0.002) with P-value (0.04).Also there was significant positive correlation between chromium level and Body Mass Index (BMI) (R-value 0.450, P-value 0.014), and significant negative correlation between chromium level and age (R-value- 0.660, P-value 0.011) , a significant strong negative correlation between chromium level and HbA1c (R-value -0.843, P-value 0.0260). Conclusion: The study concluded that, serum chromium level is significantly decrease in type II DM.

Assessment of health status in fiber glass workers: Role of chromium with biological antioxidants.

Objectives: The aim of study is to find out the role of chromium with biological antioxidant and how these can relate with the health of fiber glass workers. Study Design: Cross Sectional Study. Setting: Fiber glass industry Lahore. Period: July 2018 to Feb 2019. Material & Methods: Study was included the fifty workers of fiber glass industry with 4-5 years experience or time of exposure. A questionnaire was filled by each participant. Twenty individuals were taken as controls. Their blood sample was drawn to estimate the level of chromium and of biological antioxidants that include serum Catalase, Superoxide Dismutase, Glutathione and Malondialdehye. Results: Mean age of workers was 35 year with BMI 23.80 kg/m2. Their work duration in Fiber glass factory was 6-7 years. Levels of serum chromium and the biological antioxident was significantly high (P<0.001) in fiber glass workers as compared to the levels of these parameters of control. A positive weak correlation was observed between serum chromium and antioxidants MDA, SOD and catalase. On the other hand a moderate inverse correlation was observed between serum chromium and antioxidant GSH. Conclusion: It is concluded that high level of chromium in workers of fiber glass factory is responsible for increased levels of antioxidants in their body, which in long run may develop the diseases especially of respiratory tract.

Lower Circulating Levels of Soluble TNF-Like Weak Inducer of Apoptosis and Chromium in Treated Brucella Infection

Brucellosis is a common infectious disease around the globe. The aim of the present investigation was to evaluate the effect of brucellosis on the serum levels of chromium (Cr), lead (Pb), soluble TNF–like weak inducer of apoptosis (sTWEAK) as well as high-sensitivity C-reactive protein (hs-CRP) and homocysteine in patients suffering from brucellosis. The present case-control study was executed on 40 treated brucellosis patients (case) and 40 healthy individuals (control). Blood samples were obtained from all the participants for the measurement of the desired indices. The serum levels of chromium in the case group (0.109±0.025 μg/L) was significantly lower compared with that in the control group (0.121±0.027 μg/L, P=0.047). The levels of lead in serum were almost unchanged between the two groups (12.58±1.94 vs. 12.28±2.42 μg/dL, P=0.533). The sTWEAK levels were significantly lower in the case group as compared to the control subjects (235.20±48.45 pg/mL vs. 262.00±67.25 pg/mL, P=0.044). The levels of hs-CRP were significantly higher in the case group (2.23±0.34 mg/L) than that in the control group (2.05±0.32 mg/L, P=0.016); similarly, homocysteine levels were higher in the serum of patients in case group as compared to the control ones (16.18±4.47 µmol/L vs. 14.36±3.06 µmol/L, P=0.038). The current investigation underlined that brucellosis causes alterations in serum chromium and sTWEAK levels, the markers that are considered as the predictors of cardiovascular disease.

Serum Chromium Levels are Higher in Peritoneal Dialysis than in Hemodialysis Patients

BackgroundAn elevation in serum chromium levels in individuals treated with renal replacement therapy has been previously described, but chromium levels have not been systematically studied in patients treated with different dialysis modalities. The aim of this study was to compare serum chromium levels in patients treated with chronic peritoneal dialysis (PD) and hemodialysis (HD).MethodsWe studied 169 chronic dialysis patients in a single medical center, of which 148 were treated with HD and 21 with PD. Serum chromium levels were measured by atomic absorption spectrometry. Residual renal function was accessed using a timed urine collection for the measurement of urine output and calculation of glomerular filtration rate (GFR).ResultsThe median (interquartile range) serum chromium level was significantly higher in patients treated with PD than in patients treated with HD: 5.00 (3.24 – 6.15) vs 1.83 (1.29 – 2.45) mcg/L, p < 0.001. In a univariate analysis, serum chromium level was associated with PD modality: Exp (B) 7.46 (95% confidence interval [CI] 2.1 – 26.4), p = 0.002. The association of PD modality with serum chromium level was even more significant using a multivariate logistic regression model: odds ratio (OR) 11.87 (95% CI 2.85 – 49.52), p = 0.001 after adjustment for age, gender, diabetes, smoking, dialysis vintage, use of diuretics, and residual renal function.ConclusionsIn patients treated with chronic dialysis, serum chromium levels are higher in patients treated with PD than in those treated with HD.

Genotoxic Effects Due to Exposure to Chromium and Nickel Among Electroplating Workers

Using chromium and nickel for electroplating is important in many industries. This process induces variable adverse health effects among exposed workers. The aim of this study is to detect the genotoxic effects of combined exposure to chromium and nickel among electroplating workers. This study was conducted on 41 male workers occupationally exposed to chromium and nickel in the electroplating section of a factory compared to 41 male nonexposed individuals, where full history and clinical examination were performed. Laboratory investigations included measurement of serum chromium, nickel, 8-hydroxydeoxyguanosine (8-OHdG), and micronuclei were measured in buccal cells. In exposed workers, serum chromium ranged from 0.09 to 7.20 µg/L, serum nickel ranged from 1.20 to 28.00 µg/L, serum 8-OHdG ranged from 1.09 to12.60 ng/mL, and these results were statistically significantly increased compared to nonexposed group ( P < 0.001). Electroplaters showed higher frequencies of micronuclei in buccal cells when compared to nonexposed (ranged from 20.00 to 130.00 N/1,000 versus 2.00 to 28.00 N/1,000; P < 0.001). Linear regression models were done to detect independent predictors of 8-OHdG and micronucleus test by comparing exposed and nonexposed groups. The model found that exposure to chromium and nickel increases serum 8-OHdG by 4.754 (95% confidence interval [CI]: 3.54-5.96). The model found that exposure to chromium and nickel increases micronucleus by 35.927 (95% CI: 28.517-43.337). Serum 8-OHdG and micronucleus test in buccal cells were increased with combined exposure to chromium and nickel. The current research concluded that workers exposed to nickel and chromium in electroplating industry are at risk of significant cytogenetic damage.
