Type 2 diabetes mellitus (DM) is a chronic disease which deteriorates the quality of life with time. Type 2 DM accounts for more than 90% cases of diabetes mellitus as compared to other types of this disease. There is significant oxidative stress in type 2 DM which plays an important role in the pathogenesis of disease. In order to combat this oxidative stress antioxidant supplements have to be added as add on therapy along with treatment of type 2 DM. Vitamin C is the safest antioxidant which plays significant role in diminishing the oxidative stress. The vitamin C supplementation have good control of FBS and HbA1c and therefore helps in achieving better glycemic control along with prevention of lipid abnormalities.

Vitamin C Supplementation

Background Vitamin C is an essential element required for normal metabolic function. We investigated the effect of vitamin C supplementation on circulating miRNA (miR) expression in subjects with poorly controlled type 2 diabetes mellitus (T2DM). Changes in miR expression were also correlated with clinical measures of disease. Methods Pre- and post-vitamin C supplementation samples from five participants who had increased vitamin C levels, improved oxidative status and polymorphonuclear (PMN) function after receiving 1,000 mg of vitamin C daily for six weeks were screened for miRNA expression using the NanoString miRNA assay. Differences in miRNA expression identified from the miRNA screen were validated by qRT-PCR. Results Four miRNAs showed significantly different expression post-vitamin C supplementation relative to baseline, including the down-regulation of miR-451a (−1.72 fold change (FC), p = 0.036) and up-regulation of miR-1253 (0.62 FC, p = 0.027), miR-1290 (0.53 FC, p = 0.036) and miR-644a (0.5 FC, p = 0.042). The validation study showed only miR-451a expression was significantly different from baseline with vitamin C supplementation. MiR-451a expression was negatively correlated with vitamin C levels (r =  − 0.497, p = 0.049) but positively correlated with levels of malondialdehyde (MDA) (r = 0.584, p = 0.017), cholesterol (r = 0.564, p = 0.022) and low-density lipoproteins (LDL) (r = 0.522, p = 0.037). Bioinformatics analysis of the putative target genes of miR-451a indicated gene functions related to signaling pathways involved in cellular processes, such as the mammalian target of rapamycin (mTOR) signaling pathway. Conclusions Vitamin C supplementation altered circulating miR-451a expression. The results from this pilot study suggest that miRNAs could be used as biomarkers to indicate oxidative status in subjects with T2DM and with poor glycemic control and could lead to a novel molecular strategy to reduce oxidative stress in T2DM.

No study has ever examined the effect of vitamin C with metformin on fasting (FBS) and postmeal blood glucose (PMBG) as well as glycosylated hemoglobin (HbA1c) in the treatment of type 2 diabetes mellitus (DM). The goal was to examine the effect of oral vitamin C with metformin on FBS, PMBG, HbA1c, and plasma ascorbic acid level (PAA) with type 2 DM. Seventy patients with type 2 DM participated in a prospective, double-blind, placebo-controlled, 12-week study. The patients with type 2 DM were divided randomly into placebo and vitamin C group of 35 each. Both groups received the treatment for twelve weeks. Decreased PAA levels were found in patients with type 2 diabetes mellitus. This level was reversed significantly after treatment with vitamin C along with metformin compared to placebo with metformin. FBS, PMBG, and HbA1c levels showed significant improvement after 12 weeks of treatment with vitamin C. In conclusion, oral supplementation of vitamin C with metformin reverses ascorbic acid levels, reduces FBS, PMBG, and improves HbA1c. Hence, both the drugs in combination may be used in the treatment of type 2 DM to maintain good glycemic control.

Vitamin C Supplementation

Background: Diabetes mellitus (DM) is the most common non-communicable diseases in the present millennium which has become a global public health problem. The treatment of type 2 Diabetes mellitus (T2 DM) often is initiated with monotherapy of oral antidiabetic drugs (OADs), which often do not decrease the plasma sugar levels effectively and consistently that will reduce short term and long-term complications associated with T2 DM. Hence the current study is aimed to determine the effectiveness of vitamin C supplementation with standard OADs on glycemic control.Methods: This study consisted of 120 T2 DM patients with 80 males and 40 females with a mean age of 50.88 yrs were divided into four groups with equal number of males and females in each group depending upon the OADs they received in solo or with vitamin C for 12 weeks. After the written consent, a detail clinical history, clinical examination, biochemical investigations including fasting plasma sugar (FPS), post prandial plasma sugar (PPS), glycosylated hemoglobin (HBA1c), serum creatinine, serum electrolytes, chest X-ray PA view and standard ECG were done. Repeat FPS, PPS and HBA1c were done after 4, 8 and 12 weeks of study.Results: After 12 weeks of study FBS, PPS and HBA1c decreased significantly (p<0.01) in study groups (Metformin and teneligliptin with vitamin C) as compared to control groups (OADs without vitamin C). Vitamin C supplementation with OADs found to be effective, well tolerated and devoid of any side effects.Conclusions: OADs are effective and affordable hypoglycemic agents with vitamin C supplementation.

Objectives: To assess oxidative damage and lipid profile levels in Type 2 diabetes mellitus patients with or without tobacco chewing habit. Methods: Total of 141 newly diagnosed Type 2 diabetes mellitus patients with tobacco chewing habit from past >18 years were included, 136 Type 2diabetes mellitus without any tobacco chewing habit, 140 normal healthy subjects without any tobacco chewing habit were included in the study. Blood sample was collected after 8-12 hours fasting from each subject to estimate glucose and cholesterol. The plasma was used for estimation of total antioxidant (TAA) activity, Vitamin C and thiobarbituric acid reacting substances (TBARS) by standard methods. Statistical analysis was done with SPSS version 16. Results: The glucose, cholesterol and TBARS levels were found to be increased significantly (p<0.001) in diabetic patients with tobacco chewing habit, as well as TAA, Vitamin C levels decreased significantly (p<0.001) when compared with healthy individuals. Conclusion: We observed increased oxidative stress and declined levels of antioxidants in newly diagnosed type 2 diabetes patients with tobacco chewing habit. It is known that hyperglycemia induces oxidative stress and further facilitate the progression of diabetic complications. Bangladesh Journal of Medical Science Vol.18(1) 2019 p.78-82

Background: Diabetes is a chronic disease and sustained hyperglycemia attacks both micro vessels and macro vessels throughout the body. It is the leading cause of retinopathy, nephropathy, end-stage renal disease, non traumatic lower extremity amputations.Subjects and Methods:Twenty five (25) Patients with newly diagnosed type 2 diabetes mellitus without any signs of retinopathy were identified from outpatient services of department of Medicine and Twenty five (25) Patients with newly diagnosed type 2 diabetes mellitus with retinopathy were identified from outpatient services of department of Ophthalmology along with 25 healthy subjects were taken as controls. Diabetic retinopathy was diagnosed after doing detailed dilated fundoscopic examination as per the standard criteria.Results:The levels of FBS, HbA1c, total cholesterol, triglycerides and MDA were significantly higher in the diabetics without retinopathy, while the HDL and Vitamin C levels were lower as compared to those of the control group. The levels of FBS HbA1c, cholesterol, triglycerides and MDA were significantly higher in the diabetics with retinopathy, while the HDL and Vitamin C levels were lower as compared to those in the diabetes without retinopathy.Conclusion: The increased oxidative stress and a decreased antioxidant status can predict the micro-vascular complications in diabetes mellitus. The raised MDA levels indicate the oxidative stress and the decreased Vitamin C levels indicate the reduced antioxidant status in diabetic retinopathy.

Background: The aim of the study was to compare the hemoglobin levels among normal controls (patients) and patients of TypeII diabetes with HbA1c levels below 7 % & above 7 %.and secondly to identify the undetected cases of anemia in TypeII diabetes. Materials & Methods - 50 patients of type 2 diabetes mellitus with their glycosylated hemoglobin levels less than 7 %, 50 patients of type 2 diabetes mellitus with their glycosylated hemoglobin levels more than 7 % attending the Medicine outpatient department of Subharti Medical College and Hospital will be the subjects for the study.50 age and sex matched controls will be selected randomly from Subharti Medical College and Hospital. Informed written consent will be taken from all the subjects. The study will be conducted from January 2016 to January. Result - We studied 50 cases with HbA1C>7(poor control),50 cases with HbA1C 5.6 to7 (good control) and 50 controls with HbA1C ≤5.6, we observed in cases with HbA1C>7 (poorly control) ,the mean HbA1C is 9.9±2 and mean Hb is 9.8±1.3 as compared to cases with HbA1C 5.6 to 7(good control) where mean HbA1C is 6±0.4 and Hb is 13±0.5,this clearly indicates that in cases HbA1C is more Hb levels are low and when HbA1C is less Hb levels are higher. Conclusion - In the present study we found negative correlation between HbA1c & Hb levels. As the value of HbA1c increases, as in cases of HbA1c >7(poor diabetic control), we found low Hb levels as compared to the cases with HbA1c <7(5.6-7) (good control).
